THE  1^^/  LINEAR  STANDARD' 
20-WATT  PRE-FAB  AMPLIFIER 

Qmndlo  l^om  in  Qualiiy 
ar^ Petfoiwsnce 


Yes,  just  tighten  17  screws,  in  17  minutes,  connect  your  completed 
UTC  Pre-Fab  Amplifier  into  your  Hi-Fi  system,  then  sit  back  and  enjoy 
the  most  spine-tingling  tones  you  ever  heard  through  your  music 
system.  And  all  you  have  used  is  a  screwdriver. 

The  UTC  'Linear  Standard'  is  the  first  pre-engineered,  pre-fabri- 
cated,  pre-assembled  amplifier  kit  ever  offered  to  the  home  building 
audio  fan,  that  employs  the  latest  and  most  advanced  techniques 
including  the  printed  circuit.  You  needn't  knov/  a  tube  from  a  con- 
denser, just  how  to  use  a  screv/driver. 

More  than  a  year  of  top  level  UTC  engineering  has  gone  into  this 
amplifier  to  produce  the  cleanest,  purest,  response  you  have  ever 
heard.  It's  absolutely  linear:  no  positive  feedback,  hence  no  re- 
sponse peaks  at  either  end  of  the  spectrum.  Excellent  damping  and 
transient  response  ...  no  hangover  on  low  frequencies  to  cause 
boominess  ...  no  high  frequency  ringing.  In  short,  just  pure,  clean, 
true-to-life  response  that  sounds  as  good  as  it  tests  on  the  meter. 

And  it's  the  only  amplifier  with  a  feedback  circuit  so  stable  that  any 
one  of  the  tubes  can  be  replaced  and  still  be  perfectly  matched  to 
its  twin,  with  no  critical  circuit  readjustments  necessary. 

It  is  the  finest  amplifier  you  can  own,  and  you  can  proudly  say, 
"I  built  It  myself."

THIS  MAN  IS  DESTROYING  TUBES 
THAT  WON'T  MEET  STIFF  G-E  TESTS 


They're  being  ground  to  powder, 
in  a  G-E  factory  machine  that 
awaits  tube  rejects.  All  General  Elec- 
tric tubes  must  demonstrate  satisfac- 
tory performance  before  they're 
cartoned  and  shipped  .  .  .  any  tubes 
that  fail  in  final  tests  are  destroyed 
as  completely  unusable. 
No  "seconds",  so-called,  can  leave 
a  General  Electric  tube  plant!  The 
new  G-E  tube  you  buy  is  a  first-grade 
product  in  every  case. 


Observing  this  single  standard  of 
quality  are  seven  G-E  plants  with  the 
largest  tube  manufacturing  area  in 
the  industry  .  .  .  staffed  with  many 
thousand  trained  employees  using 
the  most  modern  precision  tube- 
building  equipment,  much  of  it  de- 
signed throughout  by  G.E. 

See  your  General  Elearic  tube 
distributor  today  for  tubes  that  are 
manufaaured  to  one  standard  of 
quality  only  . . . the  highest!

Popularity  of  Collins  Mechanical  Filters  and  Me- 
chanical Filter  Adapters  in  the  75A  Amateur  Re- 
cei\ers  has  resulted  in  many  requests  for  Mechan- 
ical Filter  Adapters  designed  for  use  in  other  pop- 
ular recei\ers. 

The  advantages  of  the  mechanical  filter  approach 
to  receiver  selectivity  may  be  immediately  rec- 
ognized. For  instance,  Filter  Adapters  eliminate 
problems  normally  associated  with  improving  re- 
ceiver selectivity.  Installation  requires  only  that 
an  IF  tube  be  removed  and  the  Filter  Adapter 
plugged  into  its  socket.  No  modification  or  dis- 
figuration is  necessary.  The  Collins  Mechanical 
Filter  Adapter  is  self-contained,  permanently  tuned, 
and  power  and  signal  circuits  are  obtained  from 
the  tube  socket.  Gain  of  the  Filter  Adapter  matches 
that  of  the  IF  tube  replaced. 

The  convenient  plug-in  feature  of  the  Filter  Adap- 
ter provides  a  means  for  selecting  a  choice  of  band- 
width for  reception  of  CW,  AM,  SSB  or  FSK.  For 
example,  the  800  cycle  bandpass  Adapter  may  be 
plugged  in  for  CW  reception;  the  1.2  kc  Adapter 
for  either  CW  or  FSK;  the  3.1  kc  Adapter  for  AM 
or  SSB;  and  the  6.0  kc  Adapter  for  AM. 

MECHANICAL  FILTERS 
ALSO  AVAILABLE 

Amateurs  desiring  Filters  for 
application  to  other  equip- 
ments now  have  a  choice  of  center  frequencies  at 
500  kc,  453  kc,  and  250  kc  —  and  bandwidth  char- 
acteristics to  fulfill  most  operating  needs.  In  the 
F455-series  (455  kc),  bandwidths  are  established 
at  0.8  kc,  1.2  kc,  3.1  kc,  and  6.0  kc.  The  F500-series 
(300  kc)  provides  a  bandwidth  choice  of  1.4  kc, 
3.1  kc,  and  6.0  kc.  For  SSB  reception  with  a  250  kc 
IF,  the  250Z-series  provides  3-2  kc  bandwidths.  A 
6.7  kc  bandwidth  is  available  in  the  F250A-67  for 
receivers  with  a  250  kc  IF.

Now  you  can  enjoy  commercial 
crystal  stability  on  SSB  at  ama- 
teur prices.  Because  of  increased 


$295 

5.0   MC.   to   5.5    MC.    Range 


demand,  PR  is  now  making  available 
Type  Z-2  Crystals  in  the  5  to  5.5  MC. 
range  at  $2.95  .  .  .  for  use  with  SSB 
exciters,  such  as  the  lOB  and  20 A  for 
operation  in  the  75  meter  and  20  meter 
phone  bands.  Pick  your  frequencies 
(integral  kilocycle)  and  order  from 
your  dealer  at  this  new,  low  price. 
Formerly  PR  crystals  in  this  range 
were  available  only  in  commercial 
types  selling  for  several  times  this 
amount. 

On  SSB,  where  stability  becomes  of 
utmost  importance,  there's  nothing 
like  crystal  control  with  PRs  .  .  .  neg- 
ligible drift  (limited  to  less  than  2 
cycles  per  MC.  per  degree  C).  You 
can  avoid  the  continuous  annoyance 
of  drift  by  depending  on  PRs  .  .  .  then 
you  KNOW  where  you  are,  and  you 
know  you  will  stay  there!

^^^  AMERICAN 
RADIO  RELAY 
LEAGUE 


INC., 


is  a  noncommerdat  associotion  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
advancement  of  the  radio  art  and  of  the  pubtic  welfare,  for  the 
representah'on  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  incorporated  association  without  capital  stock,  chartered 
under  the  laws  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu- 
facture, sale  or  rental  of  rodio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amateur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited.  A  bona  fide 
interest  in  amateur  radio  is  the  only  essential  qualification;  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  granted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us..." 


THE  YEAR  IN  REVIEW 

In  1954  the  American  Radio  Relay  League 
marked  the  40th  year  of  its  founding  as  a  non- 
profit membership  association  "of,  by  and  for 
the  radio  amateur."  It  was  a  banner  year  in 
most  respects.  Full  membership  reached  the 
highest  figure  in  our  history,  and  the  propor- 
tion voting  in  the  autumn  director  elections 
showed  this  to  be  an  active,  participating 
interest  on  the  part  of  members  in  their  na- 
tional association.  QST  continued  to  grow  in 
size  and  scope,  perhaps  soon  to  present  another 
problem  of  enlarging  the  yearly  binders  so 
that  twelve  issues  can  be  fitted  into  them! 

At  yearend  a  new  publication,  Single  Side- 
band for  the  Radio  Amateur,  appeared  in  order 
to  cater  to  and  encourage  amateur  use  of  this 
growing  field.  Considerable  publicity  on  the 
attractiveness  of  amateur  radio  as  a  hobby 
appeared  in  various  magazines,  resulting  in 
thousands  of  inquiries  to  Headquarters  on  how 
to  get  into  the  hobby,  and  also  resulting  in 
a  heavy  demand  this  year  for  "beginner" 
publications.  The  1954  financial  statement  will 
again  show  new  highs  in  gross  income  and 
outgo. 

While  it  is  only  late  November  as  we  write, 
it  appears  unquestioned  that  amateur  radio 
itself  is  reaching  a  peak  of  growth,  totaling 
perhaps  125,000  licensees.  During  the  eariy 
part  of  the  year  a  license  fee  seemed  imminent, 
but  it  has  since  been  pigeonholed.  A  major 
change  occurred  in  June  with  the  placing  of 
Novice  and  Technician  Class  examinations  on 
a  mail-only  basis,  so  that  with  the  reduced  dis- 
tance for  Conditional  Class  eligibility,  ama- 
teurs themselves  are  conducting  more  than 
half  of  FCC  exams  for  newcomers.  New 
questions  were  added  to  the  General  Class 
exam  to  expand  its  scope  and  bring  it  up  to 
date.  The  requests  to  increase  the  size  of  the 
voice  allocation  at  14  and  28  Mc.  were  turned 
down  by  FCC.  Duplex  operation  on  50  Mc. 
was  authorized,  as  was  maritime  mobile  use 
of  21  Mc.  General  approval  was  given  to  the 
security  control  program,  "Conelrad,"  _  for 
amateurs,  with  specific  proposed  regulations 
to  follow.  The  League  was  signally  honored 
with  the  visit,  in  January,  of  five  members  of 
the  Federal  Communications  Commission  and 
two  staff  Bureau  heads. 


Despite  generally  poor  conditions  for  DX, 
more  than  2600  amateurs  have  now  qualified 
for  the  DX  Century  Club  roster.  They,  with 
DXCC  aspirants,  are  encouraged  by  the 
knowledge  that  as  the  sunspot  cycle  swirigs  to 
a  more  favorable  point,  propagation  conditions 
are  rapidly  improving  and  the  now-occasional 
openings  of  21  Mc,  for  example,  will  soon 
become  everyday  occurrences.  With  more 
than  8000  individual  participants  reported, 
manning  more  than  2000  transmitter-receiver 
installations,  the  ARRL  Field  Day  was  again 
the  biggest  ever.  From  the  roars  of  "CQ  SS" 
that  covered  the  bands  those  November  week 
ends,  we'll  predict  the  same  for  that  popular 
activity.  "Above  50  Mc."  activity  has  a 
banner  year  also:  more  than  600  amateurs 
took  part  in  the  January  V.H.F.  Sweepstakes; 
a  coast-to-coast  relay  on  144-Mc.  was  com- 
pleted in  June;  and  the  10,000-Mc.  DX  record 
was  set  and  broken  three  times  during  the 
year  — it  now  stands  at  109  miles!  "Burst" 
reception  from  meteor  reflections  was  the  means 
of  several  long-distance  QSOs,  and  experimen- 
tation with  this  form  of  communication  at- 
tracted considerable  attention,  not  only  among 
amateurs  but  also  in  professional  fields. 

At  midyear  a  nationwide  test  of  civil  defense 
organization  and  facilities  showed  amateurs 
fully  ready  to  perform  their  auxiliary  commu- 
nications functions.  The  Simulated  Emer- 
gency Test  in  October  continued  to  be  another 
means  of  keeping  amateur  emergency  skills  at 
peak  efficiency.  RACES  licensing  continued 
to  grow,  with  one-half  of  the  States  already 
having  approved  plans.  Both  civil  defense  and 
normal  amateur  emergency-preparedness  or- 
ganizations performed  admirably  in  the  East 
Coast  hurricanes.  The  TVI  specter  was  re-'' 
duced  to  a  skeleton,  as  more  and  more  ama- 
teurs find  the  best  way  to  lick  the  problem  is 
to  tackle  it.  The  League's  demonstration  was 
given  at  a  number  of  western  cities,  completing 
coverage  of  the  country  where  low-band  chan- 
nels are  in  use. 

Once  again  as  we  come  to  the  close  of  a 
year  we  find  that  amateur  radio  can  take  pride 
in  an  outstanding  performance,  through  the 
organized  activities  of  its  national  association, 
and  a  meritorious  record  of  performance  "in 
the  public  interest,  convenience  and  necessity." 


OUR  COVER 

This  month's  cover  shows  the  interior  of 
W3SMQ,  Lansdowne,  Pa.  Equipment  is  com- 
pletely homebuilt,  following  designs  presented  in 
The  Radio  Amateur's  Handbook.  In  the  rack  at 
the  left  are  the  modulator  and  power  supplies.  On 
the  desk  is  a  push-pull  807  rig  running  150  watts. 
To  the  right  are  the  VFO  and  an  8-tube  superhet. 
A  Monitone  is  to  the  right  of  the  receiver,  and  a 
Handbook-design  antenna  tuner  on  the  window- 
sill,  upper  left.  Operator  and  constructor  of 
W3SMQ  is  W.  P.  Hampton. 


A.R.R.L.  QSL  BUREAU 

The  function  of  the  ARRL  QSL  Bureau  system 
is  to  facilitate  delivery  to  amateurs  in  the  United 
States,  its  possessions,  and  Canada  of  those  QSL 
cards  which  arrive  from  amateur  stations  in 
other  parts  of  the  world.  Its  operation  is  made 
possible  by  volunteer  managers  in  each  W,  K 
and  VE  call  area.  All  you  have  to  do  is  send  your 
QSL  manager  (see  list  below)  a  stamped  self- 
addressed  envelope  about  434  by  ^M,  inches  in 
size,  with  your  name  and  address  in  the  usual 
place  on  the  front  of  the  envelope  and  your  call 
printed  in  capital  letters  in  the  upper  left-hand 
corner.  (Bold-face  type  indicates  change  since 
last  QST  hsting.)

25  Years  Ago     ( 

this  month  I 

_JJLU-^        • 


January,  1930 

The  editorial  discusses  the  new  14,000-kc. 
'phone  band,  pointing  out  its  advantages  as  well 
as  potential  difficulties  which  can  result  from  bad 
judgment  and  poor  equipment. 

A  poor  man's  power  transformer  using  hand- 
wound  primary  and  filament  coils  and  junk-box 
honeycomb  coils  for  secondaries  is  described  by 
E.  H.  Harrington,  jr.,  W9CRR.  Almost  900  volts 
each  side  of  center  tap  can  be  furnished  by  the 
unit,  which  costs  about  four  dollars. 

Station  of  the  month  is  W9BAG,  owned  by 
Frank  Smolek  of  Chicago.  The  transmitter  is  a 
50-watt  crystal  rig  using  Heising  modulation  on 
'phone  and  buffer-filament  keying  on  c.w.  The 
receiver  is  a  superhet,  with  a  regenerative  first 
detector,  two  i.f.  stages,  regenerative  second  de- 
tector, and  audio.  A  two-inch  cage  suspended  45 
feet  in  the  air  between  two  steel  towers,  with  70- 
foot  aerial  and  counterpoise,  serves  as  the  radia-

More  About  V.H.F.  Auroral  Propagation 

Recent  Findings  and  Suggestions  for  Improved  Results 
BY  ROLF  DYCE,*  W2TTU 


THE  characteristics  of  propagation  associated 
with  the  northern  hghts  have  been  described 
in  the  pages  of  QST  by  Moore. ^  As  v.h.f. 
communication  equipment  has  improved,  ama- 
teur use  of  auroral  propagation  has  multipUed 
over  the  past  few  years,  especially  above  144  Mc. 
A  program  of  amateur  auroral  reporting  was 
initiated  in  1951,  some  of  the  information 
gathered  thereby  appearing  in  "The  World 
Above  50  Mc."  These  reports  were  then  sent  on 
to  Cornell,  where  a  statistical  study  has  been 
attempted.  Some  results  are  presented  here. 
Research  in  England,^  Scandanavia,^-''  Canada,* 
and  Alaska®'''  has  progressed  rapidly  since  1950, 
yielding  new  ideas  about  auroral  v.h.f.  reflections 
which  may  be  useful  to  the  amateur  for  under- 
standing the  behavior  of  such  propagation. 

Description  of  Auroral  Signals 

An  aurorally-propagated  signal  has  a  character- 
istic growl  or  hiss  due  to  a  fast  QSB  that  is  at 
an  audio  rate  up  to  several  hundred  cycles  per 


The  b.f.o.  will  usuallj^  not  give  a  clean  note,  so 
this  is  a  sensitive  test  for  signals  propagated  by 
aurora. 

Unlike  E-  or  F-layer  propagation,  strongest 
signals  are  usually  obtained  when  both  stations 
point  their  antennas  northward,  regardless  of 
the  actual  great^circle  bearing  between  stations. 
Often  all  stations  will  appear  to  come  from  the 
same  direction  in  the  north,  as  if  a  small  portion 
of  the  aurora  is  responsible  for  all  the  propagation. 
During  especially  strong  aurora,  often  accom- 
panied by  active  overhead  displays,  the  signals 
may  appear  to  come  from  a  variety  of  directions 
spread  about  north.  However,  in  general,  stations 
located  to  the  east  of  the  receiving  station  will 
have  preferable  directions  eastward  of  magnetic 
north  and  likewise  for  westerly  stations. 

Amateur  Reports 

Amateur  reports  of  auroral  propagation,  col- 
lected with  the  help  of  ARRL  and  dating  back 
to    1951,   have  been   assembled  at  the   Cornell

Ionosphere  Project.  The  individual  stations  were 
located  on  a  map,  and  the  direct  airline  distance 
was  measured  between  pairs  of  stations  reporting 
communication.  This  does  not  imply  that  the 
radio  path  was  along  this  measuring  line,  but 
merely  tells  one  at  what  distance  communication 
was  possible.  Histograms  showing  the  likelihood 
of  occurrence  of  certain  distances  are  given  in 
Fig.  1.  A  similar  graph  for  sporadic-.^  signals 
on  50  Mc.  shows  a  prominent  maximum  at  about 
800  miles,  with  a  "skip"  region  for  shorter 
distances.  However,  notice  in  Fig.  1  how  the 
probabihty  of  communication  by  auroral  prop- 
agation falls  off  with  distance.  The  graph  below 
100  miles  is  too  low  due  to  (1)  blanketing  strength 
of  direct  or  tropospheric  signal,  (2)  failure  of 
amateurs  to  log  familiar  and  nearby  stations, 
(3)  fewer  amateurs  because  the  inner  ring  con- 
tains less  land  area  and  hence  fewer  amateurs.

The  50-Mc.  data  suffer  from  the  same  errors, 
in  addition  to  the  fact  that  only  one-tenth  as 
many  reports  were  sent  in. 

The  information  contained  in  Fig.  1  gives 
a  measure  of  the  distance  over  which  auroral 
communication  is  to  be  e.xpected.  Such  informa- 
tion would  be  difficult  to  obtain  without  the  use 
of  amateur  reports.  Tliis  graph  also  supports  the 
view  that  auroral  propagation  is  not  a  skip  phe- 
nomenon, as  was  recently  suggested  in  Norway.^ 

The  144-Mc.  data  were  reexamined  and  the 
distance  between  each  pair  of  stations  expressed 
in  two  components  — a  north-south  and  an 
east-west  distance.  The  results  appear  in  Fig.  2. 
A  difference  in  the  two  components  is  clearly 
seen,  showing  that  east-west  paths  are  generally 
longer  than  north-south  paths.  This  effect  may 
be  due  to  the  oblong  shape  of  the  population 
distribution,  since  most  reports  came  from  a 
narrow  region  extending  from  Ohio  to  Massa- 
chusetts. However,  the  preference  for  east-west 
station-to-station  direction  is  also  explained  by  a 
theory  later  to  be  discussed. 

An  Auroral  Signal  Recorder 

A  scheme  for  automatically  recording  auroral 
signals  has  been  assembled  at  the  Cornell  Iono- 
sphere Project  and  has  been  operating  almost 
continuously  now  for  two  years.  Many  amateurs 
are  already  familiar  with  the  high-power  trans- 
missions continuously,  day  and  night,  from 
Cedar    Rapids,    Iowa,    on    49.6    and    49.8    Mc 


Cornell    University    at    Ithaca,    New    York,    is 
located    so    that    these    transmissions    come    in 
strongly    by    auroral    propagation,    when    it    is 
present.   It  is  possible  to  obtain  a  continuous 
record  of  auroral  openings  merely  by  attaching 
a  recording  milliammeter  to  the  d.c.  output  from 
the  detector.  The  QSB  on  an  auroral  signal  is 
too  fast  for  the  recording  pen  to  follow,  so  an 
average  value  is  painted  on  the  recording  chart 
when  auroral  signals  are  present  —  see  Fig.  3. 
Strong   and   frequent   bursts   of   signal    due    to 
meteors  can  be  obtained  over  the  Cedar  Rapids- 
to-Ithaca  path.  They  provide  an  easy  means  of 
verifying  that  the  transmitter  is  operating  and 
for  setting  the  receiver  tuning.  The  occurrence 
of  auroral  signals  as  recorded  in   this  manner 
correlates  very  well  with  such  openings  as  re- 
ported by  amateurs.  Amateurs  in  general,  and 
Michigan  amateurs  in  particular,  seem  to  have 
sharp   ears    because    even    brief   occurrences   of 
auroral  propagation  are  caught  at  least  by  some. 
Of  course,  there  are  short  periods  when  amateurs 
report  auroral  signals  when  Cedar  Rapids  has 
faded  out.  The  reverse  is  also  true.  The  recorder 
scheme    provides    a    continuous    check    on    the 
auroral  signals  throughout  the  entire  night  and 
is  therefore  useful  for  studying  daily  and  seasonal 
variation  in  the  frequency  of  occurrence  of  the 
auroral  propagation.  Records  of  auroral  signals 
are  a  help  in  early  warning  of  openings  and  in 
predicting  subsequent  openings.

gation  at  any  time  of  day  appears  in  Fig.  4. 
Isolated  cases  of  auroral  signals  have  been  ob- 
served at  almost  every  hour,  but  the  phenomenon 
is  chiefly  a  nighttime  one.  This  curve  emphasizes 
the  importance  of  observation  just  before  supper- 
time.  An  interesting  dip  near  midnight  shows 
up,  for  which  no  explanation  is  here  offered.  It 
shows  that  openings  frequently  continue  into 
the  early  morning  hours,  although  they  may  die 
out  temporarily  around  midnight.  There  are 
also  cases  of  auroral  openings  after  midnight  not 
accompanied  by  auroral  signals  earUer.  _ 

The  seasonal  variation  was  plotted  in  Fig.  5 
by  determining  for  each  month  the  percentage 
of  time  that  auroral  propagation  was  present. 
Maxima  of  auroral  propagation  can  be  seen  to 
occur  in  March  and  October,  vnth  important 
minima  in  December  and  June.  A  decrease  can 
be  seen  from  1952  to  195-t  that  is  believed  to  be 
authentic.  This  is  attributed  to  the  decrease  in 
the  sunspot  activity  over  the  past  few  years, 
expected  to  reach  a  minimum  some  time  in 
1954.  With  this  information,  one  can  better 
predict  when  auroral  signals  can  be  expected, 
or  putting  it  another  way  —  when  no  auroral 
propagation  should  be  observed. 


Position  in  Space  of  the 
Ionization  Involved 

Most  of  the  organized  research  concerning 
auroral  propagation  has  been  done  using  radar. 
That  is,  by  transmitting  only  for  a  brief  instant 
(about  1/10,000  of  a  second)  and  measuring  the 
time  for  this  pulse  to  return  to  the  receiver,  one 
can  determine  the  distance  to  the  auroral  ioniza- 
tion. Accompanied  by  a  sharply  directional 
antenna,  the  range  and  azimuth  of  auroral 
echoes  can  therefore  be  determined  by  a  single 
station. 

Some  radar  experiments  were  done  at  Cornell 
on  103  Mc,  using  a  high-powered  war-surplus 
search  radar.®  This  used  a  large  antenna  8 
dipoles  vertically  and  4  dipoles  in  width,  the 
whole  affair  being  rotatable.  Echoes  were  ob- 
tained about  400  to  600  miles  to  the  north. 
There  was  fairly  good  correspondence  between 
the  echoes  obtained  and  ray  activity  (vertical 
streaks)  seen  by  eye.  There  never  had  been 
enough  auroral  activity  to  determine  whether 
one  could  obtain  echoes  when  aurora  was  over- 
head.

RANGE     IN     KILOMETERS 

During  the  summer  of  1953,  Ken  Bowles 
(W2MTU,  ex-ZGP)  and  the  author  had  an 
opportunity  to  work  at  the  Geophysical  Institute 
at  the  University  of  Alaska.  The  Institute  is 
located  at  College,  Alaska,  a  few  miles  from 
Fairbanks.  It  is,  therefore,  only  100  miles  to 
the  south  of  the  maximum  auroral-activity 
zone  which  forms  a  ring  around  the  earth's 
magnetic  pole.  Some  observations  will  now  be 
described  that  were  performed  by  the  author 
during  1953,  and  which  are  illustrative  of  recent 
research  now  under  way  at  several  locations. 
Aurora  is  seen  frequently,  is  strong  and  occurs 
frequently  over  the  entire  sky  including  south  of 
overhead.  Hence,  this  northern  latitude  affords 
an  excellent  place  to  observe  the  effects  of  visible 
aurora  on  v.h.f.  propagation. 

Arrangements  were  made  to  operate  a  c.w. 
beacon  transmitter  on  51.9  Mc.  about  100  miles 
to  the  east.  The  signal  could  usually  l)e  heard

edge  of  the  51.7-Mc.  transmitter  pulse  is  seen  at  the  far 
left.  Two  auroral  echoes  can  be  seen  delayed  in  time 
corresponding  to  600-km.  and  720-km.  range. 


weakly  by  troposphere  propagation,  but  was 
heard  when  aurora  was  present  coming  from 
the  north  with  the  characteristic  growling  auroral 
QSB.  On  a  different  frequency  assignment  of 
51.7  Mc,  permission  was  obtained  to  install  a 
transmitter  five  miles  away  sending  pulses  150 
times  per  second,  each  being  about  100  micro- 
seconds in  duration.  The  transmitting  antenna 
was  originally  a  horizontal  dipole  to  send  radia- 
tion in  all  directions  in  the  meridian  plane.  A 
rotary  4-element  Yagi  was  then  used  for  receiving, 
using  a  low-noise  crystal-controlled  converter  and 
a  Super-Pro  receiver.  The  d.c.  detector  output 
was  fed  into  an  oscilloscope,  the  strong  direct 
signal  coming  from  the  transmitter  being  used 
to  initiate  each  sweep.  With  the  antenna  pointing 
north  during  aurora  and  with  the  51.9-Mc. 
station  coming  in  by  auroral  propagation,  weak 
echo  pulses  could  be  obtained,  and  the  range 
easily  estimated.  (See  Fig.  6.)

Ronge    (km)    From     College,  Alosko 


It  has  been  shown  by  parallactic  photograph}^ 
that  most  visible  auroral  light  comes  from  about 
the  E  region  at  a  height  of  about  60  miles,  or  100 
kilometers.  1°  One  would,  therefore,  expect  to 
encounter  echoes  as  close  —  but  no  closer  — 
than  about  100  km.,  and  also  to  find  echoes 
from  the  south  when  visible  auroral  forms  could 
be  seen  there.  This  was  quickly  seen  to  be  not 
the  true  state  of  affairs.  Echoes  were  obtained 
mainly  from  distances  greater  than  about  400 
kilometers  and  were  never  obtained  from  the 
south.  Contrary  to  expectations,  most  echoes 
came  from  places  far  to  the  north  of  the  auroral 
zone  as  shown  in  Figs.  7  and  8.  The  echoes 
clearly  came  mainly  from  the  northern  quad- 
rant. Some  continuous  film  records  of  echo  range 
were  made  at  51.7  Mc.  They  gave  the  statistical 
result  shown  in  Fig.  9,  showing  a  pronounced 
tendency  for  the  echoes  to  have  ranges  of  500  km. 
or  greater. 

To  rule  out  the  possibility  that  these  echoes 
might  be  coming  from  overhead  ionization  at 
a  height  of  500  km.,  an  antenna  with  a  vertical 
main  lobe  was  constructed  for  comparison  pur- 
poses. Six  half-wave  elements  in  a  broadside 
array  were  suspended  above  the  flat  metallic 
roof   of  the   Geophysical   building.    A   separate 


converter,  receiver,  and  oscilloscope  were  con- 
nected, so  that  the  observer  could  watch  both 
antenna  presentations  simultaneously.  Echoes 
from  meteors  were  seen  with  both  antennas, 
indicating  that  both  sets  of  receivers  were 
working  properly.  Ne.xt,  observations  of  auroral 
echo  range  were  made  when  overhead  arcs, 
bands,  rays,  and  corona  were  present.  These 
occur  frequently  at  College.  All  auroral  echoes 
were  definitely  much  stronger  on  the  rotary 
Yagi  antenna  which  was  looking  at  low  angles. 
Similar  results  were  found  with  the  106-Mc. 
radar  equipment  by  tilting  the  regular  antenna 
to  point  overhead  during  overhead  aurora. 
These  experiments  show  that  auroral  echoes 
are  (1)  from  targets  at  great  distances,  probably 
at  a  height  of  about  100  kilometers,  and  (2) 
from  low  angles  of  elevation,  no  matter  where 
in  the  sky  the  visible  auroral  forms  occur. 

At  College,  one  frequentlj-  sees  streaks  of 
auroral  Ught  rising  from  the  western  horizon, 
extending  overhead  and  down  to  the  eastern 
horizon.  It  has  already  been  shown  that  the  v.h.f. 
echoes    were    not    coming    from    the    overhead

Bands  witching  a  Crystal- Controlled 
Mobile  Converter 

Using  the  B.C.  Receiver  as  a  Tunable  I.F.  for  3.5-30-Mc.  Reception 

BY  C.  VERNON  CHAMBERS,  WIJEQ 


ALTHOUGH  the  converter  shown  in  the  photo- 
[\  graphs  was  designed  primarily  for  mobile 
-^  •*-  use,  this  relatively  simple  unit  will  add  gain 
and  stability  to  almost  any  of  the  less-expensive 
communications  receivers  that  include  the  broad- 
cast range.  While  one  might  conclude  from  its 
compactness  that  it  is  rather  difficult  to  con- 
struct, carefully  planned  subassembhes  make  the 
job  comparatively  easy.  In  a  mobile  installation, 
the  unit  can  be  suspended  directly  under  the  car 
broadcast  receiver,  where  it  is  hardly  noticeable 
and  detracts  nothing  from  the  appearance  of  the 
instrument  panel,  nor  from  the  comfort  of  front- 
seat  passengers. 

The  high-frequency  oscillator  in  a  crystal-con- 
trolled converter  is  fixed  in  frequency,  of  course. 
Therefore,  this  sj'stem  departs  from  the  more 
conventional  in  that  the  b.c.  receiver,  rather  than 
the  converter,  is  used  to  tune  over  the  ham  bands. 
The  frequency  stability  gained  by  the  use  of 
crystal  control  is  hard  to  appreciate  until  you 
have  tried  it.  Over  rough  roads,  at  any  speed, 
even  10-meter  signals  stay  put.  Only  a  jolt  hard 
enough  to  detune  the  broadcast  receiver  will 
change  the  frequency. 

Another  advantage  that  is  sometimes  over- 
looked is  the  fact  that  most  car  receivers  (and  all 
communications  receivers)  have  good  dials  that 
are  easy  to  handle  and  conveniently  located. 
This  is  in   contrast  to  the  miniature  controls 


found  on  most  tunable  mobile  converters  as  a 
result  of  the  effort  to  keep  within  minimum  di- 
mensions. Even  the  smallest  tunable  unit  requires 
space  that  is  difficult  to  find  in  a  convenient  spot 
without  interfering  with  panel  instruments  or 
leg  room. 

While  the  converter  draws  20  ma.  at  150  volts, 
tests  have  shown  that  the  performance  is  essen- 
tially unchanged  with  the  plate  input  reduced  to 
5  ma.  at  45  volts.  This  means,  of  course,  that  the 
unit  can  be  supplied  from  the  car-receiver  power 
pack  with  no  danger  whatever  of  overloading  it. 
Or,  if  you  are  reluctant  to  dig  into  the  receiver 
to  bring  a  B  -j-  lead  out,  you  can  operate  the 
converter  from  a  small  B  battery. 

The  Circuit 

The  circuit  diagram  is  shown  in  Fig.  1.  A 
6AK5  is  used  as  an  r.f.  amplifier,  and  a  6J6  dual 
triode  as  the  frequency  converter.  Since  the 
tuning  of  the  converter  is  fixed,  the  circuits  of 
the  r.f.  amplifier  must  be  broadbanded  to  pass 
all  frequencies  in  any  ham  band.  These  circuits 
consist  of  slug-cored  coils  tuned  by  the  tube 
capacitances.  However,  a  trimmer  capacitor,  C3 
in  Fig.  1,  is  included  so  that  the  amplifier  grid 
circuit  can  be  peaked  up  for  the  particular  an- 
tenna in  use,  or  in  going  from  one  end  of  the  band 
to  the  other. 

A  common  trouble  experienced  when  a  broad- 


The  input  tuning  capacitor 
(C3),  the  bandswitch,  and  Si 
are  in  line  from  left  to  right  on 
the  front  wall  of  the  chassis. 
The  tuning  slugs  for  the  coils 
may  be  adjusted  through 
holes  drilled  in  the  sides  of 
the  chassis.  Inside  the  unit, 
switch  sections  S2A  through 
S'2F  are  in  line  in  that  order 
from  front  to  rear.  Crystals  for 
the  oscillator  are  grouped  be- 
tween switch  sections  S2D  and 

S2E.

cast  receiver  is  used  as  a  tunable  i.f.  is  that 
strong  local  broadcast  signals  may  feed  in  through 
the  converter  to  reach  the  b.c.  receiver  input 
and  cause  interference.  This  effect  has  been  mini- 
mized in  this  design  by  providing  a  pair  of  wave- 
traps,  CiLi  and  C2Z/2,  at  the  input.  With  CiLi 
tuned  to  the  strongest  signal  at  the  low-frequency 
end  of  the  b.c.  band,  and  C2L2  tuned  to  the 
strongest  local  signal  at  the  high  end  of  the  band, 
the  feed-through  of  b.c.  signals  will  seldom  be 
bothersome. 

For  frequencies  above  7  Mc,  the  oscillator 
section  of  the  converter  works  at  harmonics  of 
the  crystal  frequency.  At  these  frequencies  a  cir- 
cuit is  used  which  limits  the  oscillator  output 
essentially  to  the  desired  harmonic  frequency. 
On  3.5  and  7  Mc,  the  crystals  work  at  the 
fundamental,  and  the  circuit  is  a  simple  Pierce, 
Le  being  eliminated  on  these  bands. 

For  the  sake  of  simplicity  in  the  diagram,  only 
a  single  set  of  coils  (the  14-Mc.  set)  is  shown. 
Other  coils  and  crystals  are  wired  similarly  to 
their  respective  switch  points.  Switch  section 
»S2E  is  not  used  as  an  active  switch,  its  point  ter- 
minals merely  serving  as  a  most  convenient  tie- 
point  strip  for  supporting  the  junction  of  the 
crystals  and  Le  coils.  In  the  case  of  the  7-  and 
3.5-Mc.  positions,  where  no  L%  coils  are  used,  the 
corresponding  switch  points  are  simply  wired 
together,  as  indicated. 

*Si  performs  the  switching  necessary  in  shifting 
from  ham-band  to  broadcast  input.  »Sia  and  Sib 
shift  the  antenna  from  the  converter  to  the  b.c. 
receiver,  while  Sic  turns  off  the  converter  fila- 
ments. 

As  with  a  conventional  superhet,  the  frequency 
of  the  crystal-controlled  oscillator  must  differ 
from  the  frequency  of  the  incoming  signal  by  the 
frequency  of  the  i.f.  amplifier.  In  this  case,  the 
i.f.  will  vary  from  about  550  to  1550  kc.  —  the 
usual  tuning  range  of  the  b.c.  receiver.  An  ac- 


•  Here  is  a  mobile  converter  that  in- 
cludes bandswitching  and  crystal  control 
—  features  that  add  much  to  the  oper- 
ating convenience  and  received-signal 
stability.  The  standard  car  b.c.  receiver 
is  used  as  a  tunable  i.f.,  eliminating  the 
problem  of  providing  suitable  controls 
and  space  often  involved  with  tunable 
converters.  Form  factor  has  also  received 
careful  consideration.  Plate  power  re- 
quirements are  easily  handled  by  the  car- 
receiver  supply,  or  even  a  small  B  battery, 
if  the  operator  wants  to  avoid  tampering 
with  the  b.c.  receiver. 


companying  table  shows  the  crystal  frequency, 
the  h.f.  oscillator  frequency,  and  the  range  over 
which  the  b.c.  receiver  must  be  tuned  to  cover 
each  of  the  ham  bands.  The  oscillator  works  on 
the  low-frequency  side  of  the  signal  frequency  in 
this  instance. 

Since  the  range  of  the  b.c.  receiver  is  approxi- 
mately 1000  kc.  (1550-550  kc),  the  tuning  range 
with  any  single  crystal  is  limited  to  1  Mc.  How- 
ever, this  is  more  than  adequate  for  all  except  the 
10-meter  band.  For  full  coverage  of  this  band, 
two  crystals  are  used,  as  indicated  in  the  table. 
The  two  frequency  ranges  are  from  28  to  28.9 
Mc,  and  from  28.75  to  29.7  Mc.  The  11-meter 
band  is  not  normally  included,  but  values  are 
given  so  that  this  band  may  be  substituted  for 
one  of  the  10-meter  ranges  if  desired 

Con  struc  Hon 

The  converter  is  built  into  a  2  X  7  X  7-inch 
aluminum  chassis.  The  top  cover  (actually  a 
bottom  plate  for  the  chassis,  and  not  shown  in 
the  photographs)  is  a  flat  piece  of  aluminum 
measuring  7  by  9  inches.  The  extra  inch  of  over- 
lap on  each  side  provides  lips  for  fastening  the 


Connectors  J\,J3  and  J2  are 
mounted  in  that  order,  from 
right  to  left,  on  the  rear  wall 
of  the  converter.  One-inch 
holes  in  the  side  wall  permit 
the  removal  of  tubes.  The  Yx  6- 
inch  holes  are  for  adjustment 
of  the  28-Mc.  coils.

converter  to  the  bottom  cover  of  the  b.c.  receiver 
by  means  of  machine  screws  and  metal  spacers. 

The  aluminum  bracket  for  the  large  subassem- 
bly should  be  made  first.  This  subassembly  is 
shown  to  the  left  of  the  bandswitch  in  the  front 
view  of  the  converter,  and  in  the  two  detail  pho- 
tographs. The  bracket  is  53^  inches  long  and  IJ/g 
inches  high,  with  ^-inch  Ups  bent  along  the 
bottom  and  the  rear  end.  The  detail  photographs 
identify  the  components  in  this  subassembly, 
indicating  the  holes  that  must  be  drilled  for  the 
tubes,  coils  and  r.f.  chokes. 

When  the  bracket  has  been  drilled,  place  it 
against  the  rear  wall  of  the  chassis,  and  %  inch 
in  from  the  left  side,  and  mark  the  mounting 
holes  in  the  chassis.  Then  slide  the  bracket 
against  the  left-hand  side  of  the  chassis  and  spot 
the  slug-adjusting  holes,  and  the  1-inch  holes 
that  permit  removal  of  the  tubes.  The  latter  are 
the  ones  covered  with  snap-in  buttons  in  the  rear 
view. 

The  tube  sockets  are  mounted  on  a  piece  of 
aluminum    3M   inches    long    overall,    and    IJ^

not  project  and  make  contact  with  the  band- 
switch  terminals  later.  At  the  conclusion  of  the 
wiring  of  the  subassembly,  connect  power  leads 
that  will  run  to  »Sic  and  J3,  and  attach  a  2-inch 
length  of  wire  to  Pin  5  of  the  6J6.  The  free  end 
of  the  latter  will  later  be  connected  to  /S2D. 

The  remaining  slug-tuned  coils  are  mounted  as 
a  second  subassembly  on  a  bracket  the  same  in 
size  as  the  first,  although  the  mounting  lips  must 
be  bent  in  the  opposite  direction.  The  coils  are 
arranged  in  three  groups  of  four  coils.  The  coils 
are  centered  at  the  corners  of  a  %-inch  square. 
The  first  square  is  centered  on  the  strip  and  at 
^  inch  from  the  front  edge  of  the  strip.  The 
second  square  is  centered  23/^  inches  from  the 
front  edge,  and  the  last  square  is  centered  35^ 
inches  back.  At  the  center  of  each  of  the  two 
squares  toward  the  front  a  hole  is  drilled  for  a 
1-inch  6-32  screw.  A  soldering  lug  and  a  %-inch 
metal  spacer  are  slid  over  the  screw  before  it  is 
fastened  to  the  bracket.  The  lugs  are  convenient 
grounding  terminals. 

Before   the   coils   are   mounted,    this   bracket

from  the  bracket  and  is  supported  from  it  at  the 
four  corners  by  long  6-32  screws  with  metal  spac- 
ers. It  has  %-inch  holes  opposite  the  two  inside 
coil  forms,  and  5^-inch  holes  to  clear  the  two 
r.f.  chokes. 

Before  assembling  the  unit,  the  antenna  coils 
(L3)  should  be  wound  on  each  of  the  two  L4 
forms.  Each  of  the  North  Hills  coil  forms  has  an 
extra  set  of  terminals  that  may  be  used  as  tie 
points  for  the  switch  ends  of  the  L3  windings. 
(By  judicial  use  of  these  extra  terminals,  it  is 
possible  to  complete  the  wiring  of  the  converter 
without  employing  any  additional  tie  points.)

as  before,  it  should  be  shd  against  the  right-hand 
side  of  the  chassis  while  the  slug- adjusting  holes 
are  spotted  in  the  wall  of  the  chassis. 

The  first  group  of  coils  toward  the  front  are 
the  r.f.  grid  coils,  L3L4,  and  the  plate  coils,  L5, 
are  in  the  second  group.  With  the  slug  screws 
facing  you,  the  80-meter  coils  are  at  the  upper 
left,  the  40-meter  coils  are  at  the  upper  right,  the 
20-meter  coils  at  the  lower  left,  and  the  15-meter 
coils  at  the  lower  right.  The  third  group  of  coils 
at  the  rear  include  the  trap  coils,  L2  at  the  upper 
left,  and  Li  at  the  upper  right.  Below  are  the  20-

meter  oscillator  coil  to  the  right.  The  antenna 
coils,  Ls,  should  be  wound  on  their  corresponding 
grid-coil  forms  (L4)  before  assembling. 

Only  a  single  by-pass  condenser  is  shown  in 
the  diagram  at  Ce.  Actually,  there  are  three  of 
them.  One  is  at  the  junction  of  the  cold  ends  of 
the  two  10-meter  coils,  one  for  the  3.5-  and  7-Mc. 
coils,  and  one  for  the  14-  and  21-Mc.  coils. 

The  Bandswritch 

The  bandswitch  is  made  up  from  Centralab 
Switchkit  parts  as  indicated  under  Fig.  1.  The 
wafers  are  spaced  as  follows:  index  head  to 
wafer  >S2a  —  He  inch,  »S2a  to  *S2b  — •  ^ 3'! 6 
inch,  S2B  to  <S2C  —  iKe  inches,  »S2c  to  »S2d  — 
i^-fe  inch,  *S2d  to  *S2e —  1  inch,  S2K  to  S2F 
—  1^16  inch.  The  tail  of  the  bandswitch  shaft 
should  be  cut  off  close  to  the  last  wafer,  to  leave 
space  for  J3,  but  the  two  assembly  screws  should 
be  allowed  to  extend  through  the  rear  wall  of  the 
chassis  to  strengthen  the  support.  In  assembling 
the  switch,  be  sure  to  use  the  small  fiber  washers 
between  each  ceramic  spacer  and  between  the 
wafers  and  the  spacers  to  prevent  cracking  of  the 
ceramic.  All  wafers  should  be  placed  on  the  as- 
sembly rods  so  that  the  rotor  or  "arm"  terminal 
is  the  second  terminal  to  the  left  of  the  upper 
assembly  rod,  as  viewed  from  the  front. 

The  crystals  can  be  soldered  to  the  switch  con- 
tacts after  the  switch  is  mounted  in  the  chassis. 
They  are  placed  between  <S2d  and  >S2e.  In  the 
rear-view  photograph,  the  crystals,  left  to  right, 
are  for  3.5  Mc,  7  Mc,  21  Mc,  and  the  high  end 
of  the  28-Mc.  band.  The  crystals  for  the  14-Mc. 
band  and  the  low  end  of  the  10-meter  band  are 
placed  horizontally,  one  above  the  other,  against 
the  bottom  of  the  chassis.  They  are  hidden  by 
the  group  of  three  lower-frequency  crystals. 
Prongs  taken  from  an  octal  socket  and  slid  over 
the  crystal-holder  pins  are  a  good  means  of  con- 
necting the  crystals  to  the  switch  wafers. 

The  three  controls  are  lined  up  along  the  center 
line  of  the  front  edge  of  the  chassis,  with  the  an- 
tenna trimmer,  C3,  to  the  left,  the  bandswitch  at 
the  center,  and  »Si  at  the  right.  The  two  outer 
controls  are  centered  2  inches  from  the  band- 


switch  shaft.  In  the  final  assembly  these  should 
be  mounted  first. 

Shielded  phono  jacks  (RCA  type)  are  used  for 
J I  and  J2,  and  are  placed  near  the  two  rear  cor- 
ners of  the  chassis.  In  the  rear  view,  the  antenna 
jack  is  at  the  right  and  the  output  jack  at  the 
left.  The  fiber  mountings  of  these  jacks  will  need 
to  be  clipped  off  so  that  they  will  fit  between  the 
chassis  and  the  subassembly  brackets.  These 
should  be  mounted  next,  and  the  coax  leads  run 
to  Six  and  »Sib,  keeping  the  leads  along  the  bot- 
tom corners  of  the  chassis. 

Next  the  two  subassemblies  can  be  mounted 
and  connections  made  to  the  bandswitch.  Most  of 
these  connections  can  be  made  most  easily  with 
bare  No.  16  wire.  In  addition  to  the  connections 
shown  in  the  diagram,  the  bandswitch  terminals 
immediately  to  the  left  of  the  upper  tie  rod  (as 
viewed  from  the  front)  on  <S2a  and  Szb  should  be 
connected  together,  and  then  to  the  ground 
terminal  at  the  socket  of  the  6AK5.  This  grounds 
the  inactive  L3  and  L4  coils. 

As  a  last  operation,  the  power  leads  are 
brought  to  the  power  supply  connector,  Jz,  and 
soldered  to  the  terminals. 

Power  Supply 

The  converter  requires  0.625  ampere  at  6  volts 
for  the  heaters,  and  anything  between  5  ma.  at 
45  volts  to  20  ma.  at  150  volts  for  the  plate  supply. 
This  can  be  taken  most  conveniently  from  the 
car  b.c.  receiver  by  connecting  two  leads  to  an 
audio-output-stage  socket.  It  is  preferable  to 
take  the  filament  voltage  from  this  point,  rather 
than  from  the  car  wiring,  so  that  advantage  may 
be  taken  of  any  battery-fine  filtering  that  may 
be  built  into  the  b.c.  receiver.  Plate  voltage  should 
be  taken  from  the  screen  terminal.  This  voltage 
will  usually  be  about  200,  and  can  be  dropped 
down  to  the  desired  value  with  a  series  resistor. 
A  12,000-ohm  2-watt  resistor  will  usually  be 
about  right.  This  resistor  should  drop  the  voltage 
from  200  to  approximately  75  at  about  10  ma.

ground  lead,  can  be  brought  to  a  connector 
mounted  on  the  b.c.  receiver,  or  run  in  the  form 
of  a  cable  terminated  with  a  female  plug  that 
fits  the  connector  at  the  rear  of  the  converter. 
Shielded  wire  should  be  used  for  the  cable. 

Antenna  Coupling 

With  a  small  antenna,  such  as  a  mobile  whip, 
tight  coupling  to  the  antenna  is  essential  for  best 
signal  response.  It  is  also  important  in  avoiding 
regeneration  in  the  r.f.-amplifier  stage.  There- 
fore, especially  when  the  antenna  is  a  small  one, 
it  should  be  resonant.  This  is  usually  the  case  in  a 
mobile  installation  where  the  antenna  must  be 
made  resonant  for  transmitting.  If  a  signal  gener- 
ator is  used  for  preliminary  adjustment,  it  should 
be  one  having  low-impedance  (about  50-ohm) 
output.  Here  at  the  ARRL  lab,  initial  tests  were 
made  with  a  signal  generator.  Final  tests  were 
made  with  a  standard  10-meter  whip  loaded  with 
a  Johnson  "Whipload-6,"  pread justed  to  each 


band.  The  bandswitching  feature  of  this  loading 
unit  was  most  convenient  in  changing  back  and 
forth  between  bands  along  with  the  converter. 

Adjustment 

The  high-frequency  oscillator  should  be  checked 
first,  listening  on  a  communications  receiver  at 
the  oscillator  frequencies  fisted  in  the  table.  No 
adjustment  of  the  oscillator  is  necessary  at  3.5 
and  7  Mc,  but  at  the  higher  frequencies  the  slugs 
of  the  Le  coils  must  be  adjusted  for  most  stable 
output  at  the  proper  harmonic  frequencies.  Set 
the  receiver  to  the  desired  frequency  and  adjust 
the  slug  until  the  oscillator  signal  is  heard.  To 
make  sure  that  the  oscillator  is  crystal-controlled, 
jar  the  converter.  If  the  signal  is  crystal-con- 
trolled, no  amount  of  jarring  should  change  the 
frequency.  If  it  is  not  crystal-controlled,  the  slug 
should  be  adjusted  carefully  until  the  oscillator 
locks  in  with  the  crystal.

A  Cubical  Quad  for  20  Meters 

Reviving  a  Neglected  Type  of  Beam 
BY  S.  B.  LESLIE.  JR.,*  W5DQV 


•  The  cubical  quad  enjoyed  brief  popu- 
larity when  "10"  was  in  its  glory,  but 
has  practically  disappeared  along  with 
sunspots  and  tcn-nieter  activity.  The 
author  finds  it  highly  satisfactory  on 
14  Mc.  and  offers  reasons  M-hy  it  is  worth 
serious  consideration  if  you're  thinking 
of  putting  up  a  beam. 


IN  pursuit  of  our  hobby  we  occasionally  run 
across  a  piece  of  equipment  that  performs  in  a 
satisfactory  manner,  is  easy  to  build,  simple 
to  adjust  and  low  in  cost,  j^et  for  some  unknown 
reason  is  neglected  and  forgotten  by  the  majority 
of  amateurs.  Such  is  the  case  of  the  cubical  quad 
antenna.  A  few  years  ago,  when  10  meters  was 
open,  the  quad  enjoyed  considerable  popularity. 
Many  amateurs  reported  that  it  gave  them  re- 
sults equal  to,  and  in  many  cases  superior  to,  the 
conventional  3-element  Yagi,  some  claiming  gains 
as  high  as  10  to  11  db.^-  ^  Measurements  at  ARRL 
headquarters  gave  the  quad  a  gain  of  7  to  8  db. 
over  a  reference  dipole  antenna,  a  gain  equal  to 
that  of  a  good  three-element  beam.^ 

As  10  meters  faded  out  so  did  the  quad;  the 
fellows  who  had  been  so  enthusiastic  about  it 
failed  to  carry  through  and  use  it  on  the  lower 
frequencies.  Comments  received  over  the  air 
now  indicate  that  manj'  hams  do  not  know  what 
the  quad  is  or  what  it  is  capable  of  doing.  Those 
who  are  familiar  with  it  seem  surprised  that  a 
practical  one  for  20  meters  could  be  built  and  all 
assume  it  would  be  a  monstrous  affair.  Actually, 
the  quad  occupies  less  space  and  appears  smaller 
than  a  three-element  beam. 

The  cubical  quad  consists  of  a  radiating  ele- 
ment and  a  parasitic  reflector,  usually  spaced 
0.15  or  0.20  wavelength,  both  radiator  and  re- 
flector consisting  of  square  loops  one  quarter 
wavelength  on  a  side,  making  a  total  of  one 
wavelength  around  the  loop.  This  configuration 
can  be  arranged  either  as  shown  in  Fig.  lA  or 
Fig.  IB,  that  shown  at  IB  giving  slightly  higher 
gain.^  In  some  installations  the  reflector  is  made

a  Uttle  longer  than  the  radiator  as  in  Yagi  beam 
construction,  in  others  it  is  made  the  same  length 
as  the  radiator.  In  either  case,  provision  is  made 
for  tuning  the  reflector  by  means  of  a  shorted 
stub  or  variable  condenser  in  order  to  obtain 
optimum  phasing.  These  square  loops  may  be 
thought  of  as  two  half-wave  elements  stacked 
one  quarter  wavelength  apart  with,  their  ends 
bent  to  connect  them  together,  hence  a  lower  an- 
gle of  radiation  is  obtained  than  would  be  ex- 
pected from  a  simple  two-element  beam.  Many 
of  the  early  versions  used  two-turn  loops  for 
radiator  and  reflector  but  this  served  no  purpose 
except  to  raise  the  feed-point  impedance.' 

Performance  Data 

The  amateur  literature  has  very  Uttle  to  say 
regarding  the  mode  of  action  of  the  quad  and 
anyone  interested  is  urged  to  read  the  articles 
mentioned  above.  Since  this  antenna  seemed  to 
have  several  advantages  over  the  Yagi  and  as 
very  little  e.xperimental  work  had  been  reported 
on  it,  a  scale  model  for  the  50-Mc.  band  was  built 
to  try  to  determine  some  of  its  characteristics. 
All  measurements  were  made  with  the  center  of 
the  array  one  wavelength  above  ground  and  the 
instruments  used  were  a  Heathkit  AM-1  antenna 
impedance  meter,  a  Millen  grid-dip  oscillator  and 
a  homemade  field-strength  meter.  The  test  signal 
was  furnished  bj^  a  transmitter  feeding  into  a 
dipole  elevated  one  wavelength  above  the 
ground  and  located  three  wavelengths  from  the 
antenna  being  tested.   All  measurements  were 


Jcmucuy  1955 


double-checked  on  two  different  occasions  to 
make  them  as  accurate  as  the  instruments  would 
permit.^  The  results  are  tabulated  below:

The  gain  figures  seem  high  but  they  are  the 
actual  readings  obtained.  The  radiating  element 
alone,  without  reflector  or  director,  gave  a  con- 
sistent gain  of  2  db.  over  a  well-matched  and 


and  reflector.  Such  a  beam  might  prove  consider- 
ably better  than  a  three-  or  four-element  Yagi. 
Time  limitations  prevented  investigating  these 
possibilities,  but  it  is  hoped  that  the  above  exper- 
imental work  will  stimulate  more  work  on  the 
quad  by  other  amateurs.  This  beam  is  worth 
much  more  attention  than  it  has  received  in  the 
past. 

The  20-meter  quad  here  at  W5DQV  has  created 
considerable  interest,  nearly  half  the  stations 
contacted  asking  for  more  information  about 
its  operation  and  construction.  After  fourteen 
months'  operation  on  20  c.w.,  this  antenna  has 
proven  its  worth  as  it  has  given  results  equal  to 
and  often  superior  to  the  three-element  wide- 
spaced  beam  it  replaced.  It  is  definitely  smaller 
than  the  usual  three-element  beam,   having  a

trimmed  dipole.  This  does  not  agree  with  the 
published  figures  for  a  square  loop;  nevertheless, 
this  2-db.  gain  was  obtained  on  two  different 
occasions,  using  different  loops  and  different 
dipoles,  all  grid-dipped  to  the  correct  length.  Dis- 
regarding this  2-db.  gain  of  the  square  loop,  the 
0.20  spaced  quad  still  gives  a  gain  of  8  db.,  a  very 
respectable  gain  indeed. 

A  field  pattern  taken  with  the  reflector  at  0.15 
is  shown  in  Fig.  2.  A  pattern  taken  at  0.20 
showed  a  similar  outline  but  with  somewhat 
greater  attenuation  of  the  back  lobe. 

The  radiation  from  the  sides  of  these  test  beams 
and  the  one  used  on  20  meters  was  remarkably 
low,  the  field-strength  meter  indicating  almost 
zero  off  the  sides.  On-the-air  tests  with  the  20- 
meter  quad  showed  a  45-db.  front-to-side  ratio 
and  25-db.  front-to-back  ratio.  A  square  element 
tuned  as  a  director  and  spaced  0.20  wavelength 
gave  a  gain  of  5  db.  over  the  dipole,  which  brings 
up  the  interesting  possibility  of  a  three-element 
quad  using  0.15  or  0.20  spacing  for  both  director 

^  Antenna  measurements  of  any  type  tend  to  be  tricky, 
even  with  elaborate  and  accurately-calibrated  equipment, 
because  of  the  difficulty  of  detecting  and  eliminating  stray 
effects  which  sometimes  are  of  the  same  order  of  magnitude 
as  the  quantities  under  investigation.  Results  such  as  those 
tabulated  here  (and  other  similar  tabulations  of  antenna 
performance  figures)  are  of  considerable  value,  practically, 
if  it  is  kept  in  mind  that  they  are  necessarily  approximations, 
useful  as  a  guide  but  not  to  be  taken  as  literally  as,  say, 
the  reading  of  a  good  quality  d.c.  voltmeter.  —  Ed.

Construction 

Most  of  the  details  of  construction  can  be  seen 
in  the  photo  and  drawings.  It  was  built  to  be  as 
light  as  possible  and  while  it  does  whip  some  in 
the  wind,  this  does  not  seem  to  cause  any  notice-

There  is  nothing  critical  in  the  construction  ex- 
cept the  length  of  the  wire  elements,  and  no 
doubt  many  will  devise  better  ways  to  build  and 
support  this  antenna.  One  of  the  quads  built  by  a 
local  ham  used  1  X  2-inch  pine  for  the  support 
arms  but  this  beam  was  much  too  heavy  and 
blew  down  in  the  first  light  wind.  The  support 
arms  shown  in  the  drawing  are  ordinary  bamboo 
fishing  poles  about  16  feet  long,  with  the  butt 
ends  wrapped  with  friction  tape  to  prevent  the 
metal  mounting  bracket  and  wire  from  biting 
into  the  bamboo.  These  arms  are  fastened  to  the 
mounting  brackets  as  shown  in  Fig.  3  with  several 
turns  of  No.  14  galvanized  wire,  and  the  far  ends 
are  not  trimmed  until  the  antenna  wire  has  been 
fastened  in  place.  Two  mounting  brackets  and 
eight  bamboo  support  arms  are  required.  The 
mounting  brackets  serve  to  hold  the  arms  in 
place  and  to  fasten  them  to  the  end  of  the  boom. 
These  brackets  are  made  by  welding  two  24-inch 
lengths  of  1-inch  angle  iron  together  back  to  back 
to  form  a  large  "X"  90  degrees  between  legs,  and 
welding  a  5-inch  length  of  IJ^-inch  strap  iron 
between  two  of  the  legs  to  fasten  the  "X"  to  the 
boom  end.  The  arms  are  assembled  and  the  an- 
tenna wire  is  fastened  in  place  before  attaching 
the  brackets  to  the  boom. 

Many  amateurs  wiU  raise  their  eyebrows  at 
the  idea  of  using  fishing  poles  in  construction  of 
an  antenna,  but  if  the  poles  are  well  treated  with 
a  weatherproofing  compound  they  wiU  last  sev- 
eral years.  Weatherproofing  compounds  are  avail- 
able at  all  lumber  dealers.  This  antenna  has  been 
up  for  over  a  year  in  all  sorts  of  weather  and  as 
yet  shows  no  signs  of  wear.  Be  sure  to  get  straight 
poles  with  no  splits  in  them.  No  insulators  are 


necessary,  the  poles  themselves  acting  as  long 
insulators.  The  antenna  shown  in  the  photo  uses 
plastic  insulators  but  subsequent  beams  have 
shown  these  to  be  unnecessary.  The  easiest  way 
to  mount  the  antenna  wire  on  the  arms  is  to  lay  a 
long  length  of  wire  on  the  ground  and  mark  it  at 
quarter-wave  intervals,  in  this  case  16  feet  9 
inches,  and  use  these  marks  to  indicate  where  the 
wire  fastens  to  the  pole.  Fasten  loosely  at  first 
as  it  will  be  necessary  to  slide  these  joints  up  and 
down  the  poles  a  little  until  all  four  sides  of  the

A  Discussion  of  Receiver  Performance 

Some  Fine  Points  and  Unsolved  Problems  of  Receiver  Design 
BY  E.  W.  PAPPENFUS.*  W0SYF 


•  Here  is  an  article  on  receivers  that  any- 
one with  the  slightest  interest  in  "why" 
should  not  pass  up.  It  won't  tell  you 
how  to  build  anything,  unless  you  read 
carefully  between  the  lines,  but  it  will 
certainly  help  you  to  understand  some 
eflfects  that  may  have  been  a  mystery  up 
to  now. 


SINCE  good  communication  superheterodyne 
I  receivers  have  been  available  for  about 
twenty  years,  it  is  surprising  that  there  is 
anything  left  to  discuss  about  this  line  of  equip- 
ment. However,  the  large  number  of  letters  that 
are  written  to  the  manufacturers  questioning 
receiver  performance  points  to  the  need  for  a 
discussion  of  the  action  of  a  receiver  under  certain 
conditions.  These  include  weak-signal  reception 
as  well  as  performance  in  the  presence  of  a  very 
good  signal.  Many  hams  feel  that  there  is  no 
need  to  miss  a  QSO  because  a  signal  is  weak. 
They  feel  that  if  a  signal  can't  be  read,  it  is 
strictly  the  fault  of  the  set  design.  At  the  same 
time,  it  is  hard  for  many  radio  operators  to  un- 
derstand why  a  receiver  cross-modulates  and 
blocks  when  the  kilowatt  station  next  door  comes 
on  the  air.  As  you  may  guess,  this  is  a  discussion 
of  the  reasons  why  a  receiver  is  not  all  the  ama- 
teur expects  and  perhaps  also  a  defense  of  receiver 
design. 

The  subjects  to  be  discussed  include  receiver 
sensitivity,  signal-to-noise  ratio,  noise  figure, 
cross-modulation  and  blocking.  It  is  self-evident 
that  a  receiver  for  amateur  use,  and  particularly 
for  DX,  must  have  a  great  deal  of  inherent  ampli- 
fication. The  ability  of  a  receiver  to  make  a  lot 
of  sound  in  the  loudspeaker  with  a  very  weak 
signal  is  called  "sensitivity."  High  sensitivity  in 
a  receiver  is  a  necessary,  but  not  sufficient, 
definition  of  weak-signal  receiver  performance. 
"Signal-to-noise  ratio"  is  also  very  important. 

It  is  not  quite  as  apparent  that  a  good  com- 
munications receiver  must  be  free  from  over- 
loading or  cross-modulation  when  strong  signals 
are  present.  These  undesirable  effects  are  gener- 
ally overlooked  in  the  general  confusion  and 
congestion  of  the  present-day  amateur  bands. 
It  must  be  admitted  that  the  modulation  splatter 
blamed  on  the  local  amateur  at  the  other  end  of 
the  band  is  sometimes  generated  in  the  receiver. 
It  is  unfortunate  that  a  receiver  designed  for 
very  good  weak-signal  performance  should  have 
difficulty  with  extremely  strong  signals.  This, 
however,  is  the  case,  and  it  is  an  area  in  which

an  engineering  compromise  must  be  reached.  Like 
most  compromises,  it  is  open  to  argument,  and 
there  is  no  completely  clinching  evidence  to 
prove  that  the  receiver  design  was  right.  The 
compromise  involves  r.f.  stage  gain,  a.v.c.  charac- 
teristics, r.f.  selectivity,  type  of  r.f.  tubes,  type 
of  mixer  tube,  and  mixer  noise.  With  all  of  these 
balancing  factors  it  may  be  seen  that  it  is  not 
an  easy  decision  for  the  set  designer. 

The  signal-level  chart  for  a  75A-3,  shown  in 
Fig.  1,  will  help  to  explain  some  of  the  items  dis- 
cussed previously.  In  developing  this  chart,  a 
signal  generator  was  set  for  a  convenient  level 
at  the  antenna  and  then  moved  back,  stage  by 
stage,  toward  the  diode  detector.  The  signal 
generator  output  was  adjusted  to  hold  constant 
diode-load  voltage  at  each  point  in  the  circuit 
and,  of  course,  the  frequency  was  changed 
appropriately  at  the  i.f.  amplifier.  The  signal 
generator  was  then  returned  to  the  antenna 
terminals  and  increased  to  simulate  a  stronger 
signal.  Again  the  signal  generator  was  moved 
toward  the  second  detector  holding  diode-load 
voltage  constant.  Moving  the  signal  generator 
along,  stage  bj^  stage,  is  equivalent  to  a  voltage 
measurement  at  that  point.  A  family  of  curves 
was  generated,  as  shown,  that  gives  a  complete 
picture  of  receiver  performance  with  various 
r.f.  input  levels.  A  change  in  gain  is  represented 
by  a  change  in  slope  of  the  curve.  Note  the  con- 
stant gain  of  antenna  link  to  first  r.f.  grid,  and 
the  reduction  in  gain  due  to  a.v.c.  in  the  first  r.f. 
stage  and  the  i.f.  amplifiers.  It  is  clear  how  the 
gain  of  the  five  controlled  stages  changes  to  hold 
the  diode-load  voltage  almost  constant. 

A.V.C. 

The  basic  function  of  automatic  volume  con- 
trol in  a  receiver  is  to  keep  the  diode-load  voltage 
constant  and  thus  hold  constant  audio  output  for 
changing  signal  levels.  This  is  apparent  from 
Fig.  1,  because  the  diode-load  voltage  does  not 
rise  appreciably  above  8  volts  as  the  signal 
level  is  changed  from  1.5  to  100,000  microvolts. 
This  constancy  of  receiver  output  voltage  does 
not  tell  the  whole  story,  however.  It  is  important 
to  "delay"  the  application  of  a.v.c.  voltage  until 
a  suitable  signal-to-noise  ratio  is  reached.  This 
allows  the  receiver  output  to  increase  in  a  linear 
manner  with  input  signal  level  so  that  receiver 
noise  is  rapidly  overcome.  In  the  75A-3  the  a.v.c. 
does  not  become  effective  until  the  input  signal 
is  about  1.5  microvolts.  In  addition,  some  sets 
delay  the  application  of  a.v.c.  voltage  to  the  r.f. 
stage  until  even  higher  signal  levels  are  reached. 
This  also  contributes  to  a  linear  improvement 
in   signal-to-noise  ratio  as   the  input  signal  is

QST  for 


increased  above  the  a.v.c.  threshold.  As  an 
example  of  delayed  a.v.c.  action,  if  a  2-microvolt 
signal  gives  a  10-db.  signal-to-noise  ratio,  then 
a  20-db.  increase  to  20  microvolts  will  give  a  30- 
db.  signal-to-noise  ratio.  A  10-db.  signal-to-noise 
ratio  provides  a  good  readable  signal,  but  a  signal 
with  less  noise  is  more  enjoyable  and  less  tiring 
to  the  operator. 

By  dividing  the  a.v.c.  voltage  applied  to  the 
r.f.  stage  in  the  75A-3,  suitable  action  is  obtained 
without  separately  delaying  the  r.f.  stage  a.v.c. 
voltage.  Since  a  sharp-cut-off  tube  is  used  in  the 
75A-3  r.f.  stage,  there  is  a  secondary  reason  to 
limit  a.v.c.  voltage  to  this  tube.  A  6BA6  is  a  better 
tube  for  a.v.c.  action,  but  unfortunately  it  is  a 
very  noisy  tube  compared  with  the  6CB6  that 
is  used. 

Manual  gain  control  in  the  75A-3  operates  on 
the  a.v.c.  line,  just  as  the  automatic  volume  con- 
trol does.  This  means  that  the  gain  distribution 
is  proper  for  any  reasonable  setting  of  the  manual 
gain  control.  It  is  possible  to  degrade  the  signal- 
to-noise  ratio  with  manual  gain  control  if  too 
much  gain-adjusting  action  is  applied  to  the  r.f. 
stage,  so  that  mixer  noise  is  proportionally  larger. 
Noise  tests  on  a  receiver  should  be  made  at 
various  signal  levels  to  insure  that  manual  gain 
control  is  applied  to  the  proper  stages. 

Weak  Signals 

It  is  possible  to  put  a  large  amount  of  over-all 
amplification  in  a  receiver  because  the  amplifica- 
tion at  a  given  frequency  can  be  held  to  a  manage- 
able level  through  the  use  of  the  superheterodyne 
principle  in  single-  or  multiple-conversion  (75A) 
schemes.  The  gain  from  antenna  to  loudspeaker 
in  a  typical  communications  receiver  may  be 
as  great  as  10  million,  but  all  this  gain  does  not 
permit  the  amateur  to  copy  a  weak  DX  station 
unless  the  noise  contributed  by  the 
antenna-coupling  circuit,  the  first 
r.f.  tube  shot  noise,  mixer  noise,  etc., 
is  held  to  a  low  value.  That  is  the 
reason  receiver  performance  is  speci- 
fied by  signal-plus-noise-to-noise  ratio. 
A  signal  generator  modulated  30  per 
cent  at  400  c.p.s.  (to  simulate  a 
speech  signal)  is  fed  into  the  receiver 
antenna  terminal.  The  proper  resistor 
is  placed  in  series  to  match  the  re- 
ceiver input  impedance.  The  signal 
generator  output  is  increased  until 
there  is  a  10-db.  increase  in  the 
reading  of  an  output  meter  con- 
nected  to    the   receiver   audio    over 


Fig.  1  ■ — ^  A  signal -level  chart 
of  the  75A-3  receiver,  showing 
the  signal  levels  that  exist  through

signals  and  bias  voltages. 


the  level  present  when  the  modulation  is  switched 
off.  This  means  that  the  signal  (modulated 
portion)  plus  noise  is  10  db.  stronger  than  the 
noise.  A  signal  10  db.  stronger  than  the  noise 
level  is  acceptable  for  voice  communications, 
hence  the  justification  for  this  value.  A  good  c.w. 
operator  can  copy  signals  with  a  lower  signal-to- 
noise  ratio,  but  the  lower  the  signal-to-noise 
ratio,  the  more  expert  the  operator  must  be. 

It  is  dangerous  to  generalize,  but  it  is  possibly 
safe  to  say  that  any  amateur  receiver  with  a 
10-db.  signal-to-noise  ratio  at  from  1  to  3  juv. 
is  in  the  high  quality  class.  Noise-figure  tests  ^  of 
receiver  performance  make  use  of  a  noise  diode 
and  are  the  only  real  means  of  comparison  be- 
tween receivers  of  different  bandwidth,  because 
receiver  noise  voltage  varies  proportionally  to 
the  square  root  of  the  bandwidth.  A  narrow-band 
receiver  should  not  be  compared  directly  with 
a  wide-band  set.  Noise  figure  expresses  the  ratio 
in  db.  between  the  noise  level  of  the  receiver  under 
test  to  a  so-called  perfect  receiver  in  which  all 
noise  is  assumed  to  be  generated  in  the  dummy 
antenna  due  to  its  thermal  noise.  (See  Appendix.) 

It  can  be  shown  that  a  perfect  receiver  with 
6-kc.  bandwidth  and  100-ohm  input  would  re- 
quire 1.4  /iv.  to  have  a  10-db.  signal-plus-noise- 
to-noise  ratio.  This  receiver  when  operated  with 
a  dummy  antenna  matching  the  receiver  input 
impedance  has  a  3-db.  noise  figure.  It  is  the- 
oretically possible  to  improve  the  noise  figure 
by  mismatching  the  antenna,  but  this  is  not 
important  from  a  practical  standpoint  in  the 
ham  bands  from  10  to  160  meters,  because  the 
antenna  impedance  cannot  be  predicted  ac- 
curately. Again  a  compromise  in  design  results, 
and  a  100-ohm  input  impedance  was  selected  for

the  75A-3.  Since  signal  generators  are  generally 
available  and  noise  diodes  are  not,  it  is  customary 
to  use  the  signal  generator  method  with  10-db. 
signal-plus-noise-to-noise  as  the  standard  of 
comparison  between  receivers.  Incidental  fre- 
quency modulation  in  the  signal  generator  can 
cause  errors  particularly  at  high  frequencies 
and  should  be  guarded  against. 

Noise  in  a  receiver  results  from  so-called 
thermal-agitation  noise  in  the  input  circuit, 
shot  noise,  mixer  noise  and  amplifier  noise. 
Pentagrid  mixers  are  particularly  noisy  tubes, 
but  they  are  advantageous  because  of  the  ease 
with  which  the  oscillator  can  be  fed  into  the 
mixer  and  the  freedom  from  coupling  of  oscillator 
voltage  to  the  signal  grid. 

If  enough  gain-producing  elements  precede 
the  mixers,  then  the  mixer  noise  can  be  neglected. 
Since  the  greatest  gain  exists  from  the  grid 
circuit  of  the  first  r.f.  amplifier  to  the  receiver 
output,  it  is  logical  to  expect  this  noise  to  be 
louder  than  any  other  receiver  noise.  This  is 
not  always  true,  but  in  a  properly  designed  re- 
ceiver the  input  noise  makes  the  greatest  contri- 
bution to  over-all  receiver  noise.  This  can  be 
demonstrated  by  peaking  the  grid  circuit,  with

a  resistor  of  proper  value  across  the  antenna 
terminals.  A  rise  in  receiver  noise  output  when 
the  first  r.f.  tank  circuit  is  tuned  compared  with 
the  completely  detuned  condition  indicates  the 
proper  gain  distribution.  A  drop  in  noise  level  as 
the  first  r.f.  tube  is  removed  also  shows  that  the 
mixer  noise  is  not  an  important  factor  in  over-all 
receiver  signal-to-noise  ratio.  Two  r.f.  stages  are 
generally  not  required  to  approach  the  ideal 
weak-signal  receiver  performance,  because  a  sin- 
gle stage  using  a  high-transconductance  tube  will 
amplify  the  signal  sufficiently  to  override  the 
mixer  noise.  The  chart  of  Fig.  1  shows  the  equiva- 
lent noise  present  at  the  mixers.  The  gain  here 
appears  sufficient  to  override  completely  the 
mixer  noise  with  1.5-/oiv.  input. 

If  this  peaking  effect  of  noise  with  antenna 
terminals  properly  loaded  with  a  resistor  is  not 
found,  then  the  antenna  coil  gain,  antenna 
circuit  Q  or  r.f.  amplifier  gain  should  be  adjusted 
until  the  receiver  noise  is  dominated  by  the 
receiver  input  noise.  Only  then  can  the  operator 
say  that  his  receiver  is  able  to  hear  the  weakest 
stations.  This  actually  is  a  rather  theoretical 
consideration  because  of  the  large  amount  of 
static  and  interference  prevalent,  except  perhaps 


on  the  10-meter  band.  When  the  weakest  reading 
on  the  S- meter  across  the  entire  20- meter  'phone 
band  is  S6  to  S9,  because  of  a  solid  array  of  strong 
signals,  obviously  receiver  noise  is  not  then  the 
limiting  factor.  Receiver  bandwidth  is  much  more 
important.  Atmospheric  and  manmade  static 
on  the  antenna  also  limit  the  signals  that  can 
be  copied.  Only  rarely  can  the  full  signal-to- 
noise  capabilities  of  a  receiver  be  used.  This  can 
be  checked  by  tuning  to  an  unused  portion  of 
the  band  (that's  a  joke,  son)  and  then  removing 
the  antenna  from  the  receiver  and  replacing  it 
with  the  equivalent  resistance.  If  the  receiver 
noise  output  drops,  then  the  antenna  noise  is  the 
limiting  factor  and  not  the  noise  developed  within 
the  receiver. 

Strong  Signals 

For  the  reception  of  strong  signals,  an  addi- 
tional receiver  requirement  is  added.  Radio- 
frequency  voltages  applied  to  any  stage  of  the 
receiver  must  not  exceed  the  bias  for  that  stage 
with  any  signal  ordinarily  encountered.  Fortu- 
nately, the  receiver  a.v.c.  voltage  increases  the 
bias  applied  to  each  stage  and  at  the  same  time 
reduces  the  gains  through  the  receiver  when 
strong  signals  are  tuned  in. 

Five  controlled  stages  are  used  in  the  75A-3 
a.v.c.  circuit.  By  removing  one  controlled  stage 
or  by  reducing  the  proportion  of  a.v.c.  voltage 
fed  to  a  stage,  it  is  possible  to  change  the  re- 
ceiver gain  distribution.  The  set  designer  has 
this  "handle"  by  which  he  can  set  the  gain 
curve  to  the  desired  shape.  The  curves  of  Fig. 
1  show  sufficient  r.f.  gain  adjustment  so  that  the 
mixers  are  protected  from  large  signal  volt- 
ages for  any  signal  within  the  range  of  the 
S-meter.  Because  mixers  are  somewhat  critical 
in  the  application  of  bias,  the  first  and  second 
mixers  are  omitted  from  the  controlled  circuit 
and  set  at  a  suitable  bias  by  voltage  drop  across 
a  cathode  resistor.  The  exact  gain  distribution 
within  a  receiver  is  not  critical  within  the  limita- 
tion that  all  stages  must  be  held  below  the  over- 
load region  with  the  highest  signal  level  ordinarily 
encountered. 

Strong  signals  outside  the  passband  can  reduce 
the  set  gain  if  rectified  grid  current  flows  in 
any  stage  which  can  charge  up  the  a.v.c.  line. 
A  decoupfing  resistor  and  a  low-resistance  a.v.c. 
fine  minimize  this  effect. 

Representative  voltages  for  0.5-volt  input  are 
1.5  volts  on  the  r.f.  grid  and  1.1  volts  on  the 
second  mixer  grid.  At  these  voltage  levels  the 
mixer  draws  grid  current  and  its  conversion  gain 
is  reduced.  The  overload  point  for  a  receiver 
is  defined  as  that  input  level  at  which  a  6-db. 
drop  in  audio  output  occurs  compared  with  the 
maximum  audio  output  as  the  input  signal  is 
increased.  Overload  point  for  the  75A-3  is  at 
1.4  volts.  A  small  amount  of  grid  current  in  the 
mixer  is  not  serious,  as  indicated  by  the  fact  that 
the  overload  point  is  well  above  the  input  at  which 
the  peak  r.f.  grid  voltage  appfied  to  the  second 
mixer  exceeds  its  bias. 


26 


QST  for 


All  s.s.b.  operators  will  cry  out  loudly  at  the 
above  statement.  It  is  possible  to  tolerate  grid 
current  in  a  receiver  mixer  because  the  perform- 
ance standards  are  so  much  lower  than  in  linear 
amplifiers.  In  a  s.s.b.  transmitter  it  is  desirable 
to  keep  intermodulation  products  down  30  db. 
Harmonic  distortion  of  the  signal  in  a  receiver 
can  be  tolerated  if  it  is  10  to  20  db.  below  the 
signal  level.  This  explains  the  ability  of  the  re- 
ceiver mixers  to  operate  satisfactorily  with  small 
positive  grid  voltages. 

For  the  reception  of  weak  signals  described 
earlier,  it  is  desirable  to  have  as  much  gain 
as  possible  ahead  of  the  mixers.  This  would  insure 
that  the  signal  level  would  be  strong  enough  to 
override  completely  the  noise  from  the  pentagrid 
mixers.  However,  from  the  standpoint  of  strong 
signals,  it  is  desirable  to  have  low  amplification 
until  the  selectivity  of  the  receiver  is  effective. 
This  would  insure  that  only  signals  in  the  i.f. 
passband  would  tend  to  overload  the  set  and  these 
could  be  more  readily  accommodated  by  the  high 
a.v.c.  bias  and  gain  control  that  is  effective  in  the 
i.f.  amplifier.  These  requirements  for  no  amplifi- 
cation ahead  of  selectivity  for  strong  signal 
reception  and  high  gain  in  the  antenna  circuit 
and  r.f.  stage  for  weak  signal  reception  are  in 
direct  conflict.  It  is  fortunately  possible  to  make 
an  engineering  compromise  that  will  accommo- 
date the  majority  of  operating  situations  which 
confront  the  amateurs.  Weak  signals  can  be 
handled  by  using  just  enough  r.f.  stage  gain  to 
override  the  mi.xer  noise  by  about  6  db.  or 
slightly  more. 

Cross-Modulation 

When  the  receiver  is  tuned  to  a  weak  signal, 
and  a  strong  signal  is  present  outside  the  i.f. 
passband,  then  a  different  condition  prevails 
than  in  the  strong-signal  case  outlined  above. 
There  is  very  low  a.v.c.  bias  generated  to  protect 
the  grids  of  r.f.  and  i.f.  amplifiers  from  grid  cur- 
rent and  only  moderate  gain  reduction  to  prevent 
strong  signals  from  stage  to  stage  in  the  receiver. 

The  only  gain-reducing  elements  present  are 
a  small  amount  of  a.v.c.  bias  generated  by  the 
desired  signal,  and  the  selectivity  of  the  r.f. 
and  variable-i.f.  coils  in  double-conversion  re- 
ceivers. The  selectivity  of  these  coils  determines 
the  r.f.  voltage  applied  to  mixers  and  i.f.  ampli- 
fiers. With  very  large  signals  applied  to  any  stage 
of  the  receiver,  nonlinear  operation  causes  modu- 
lation components  of  the  strong  signal  to  appear 
on  the  weak  signal.  This,  in  effect,  means  that 
strong  'phone  signals  outside  the  selectivity  curve 
of  the  i.f.  amplifier  can  still  be  heard.  The  term 
"cross-modulation"  has  been  applied  to  this 
effect.  Cross-modulation  in  a  receiver  is  measured 
by  a  laboratory  set-up  as  shown  in  Fig.  2.  Two 
signal  generators  are  used  to  simulate  the  two 
signals.  One  signal  generator  feeds  the  receiver 
through  a  resistor  equal  to  the  input  impedance 
while  the  other  signal  generator  feeds  through 
a  resistor  of  ten  times  the  input  impedance.  The 
resulting  impedance  is  then  very  close  to  the 
matching  value.   The   signal  generator  feeding 


through  the  large  resistor  is  set  for  a  value  of 
r.f.  that  will  produce  an  antenna  terminal  signal 
of,  say,  10  MV.  (approximately  S6)  at  receiver 
center  frequencj-.  The  audio  output  is  measured 
and  signal  generator  modulation  is  removed. 
The  second  signal  generator  is  then  turned  on 
and  adjusted  for  30  per  cent  modulation.  At 
various  frequencies  near  the  receiver  center  fre- 
quency the  r.f.  level  from  the  second  signal 
generator  is  increased  until  the  receiver  audio 
output  is  10  db.  less  than  that  measured  with  the 
first  signal  generator.  A  plot  of  these  values  for 
the  75A-3  operating  at  4.0  Mc.  is  shown  in 
Fig.  3.  Adjacent  signals  at  S9  -1-  40  db.  can 
interfere  if  they  are  closer  than  15  to  20  kc. 
from  the  desired  signal.  Approximately  50-kc. 
separation  is  required  for  signals  that  are  60 
db.  above  S9.  The  cross-modulation  curve  of 
Fig.  3  is  an  inverse  composite  of  the  receiver 
input  selectivit^^  The  lower  part  of  the  curve 
is  determined  by  the  selectivity  of  the  receiver 
circuits  to  the  second  mixer  grid  and  the  upper 
part  of  the  curve  is  shaped  by  the  selectivity

number  of  cross-modulation  tests  to  determine 
proper  r.f.  stage  conditions.  There  does  not  seem

A  Simple  Rig  for  Six-Meter  Mobile 

A  Compact  Transmitter  That  Is  Easy  on  Both  Pocket  book  and  Battery 

BY  R.  J.  CARPENTER,  *  W30TC 


•  In  at  least  two  respects  the  50-Mc. 
band  is  ideal  for  mobile  operation.  The 
average  car  radio  whip  is  the  right 
length,  and  low  power  will  do  the  job 
well  enough  so  that  nothing  in  the  way 
of  special  batteries  or  generators  is  re- 
quired. Here's  a  6-nieter  rig  compact 
enough  for  steering-post  mounting. 
It  uses  only  two  tubes,  and  will  work 
nicely  on  a  small  receiver-type  vibrator 
supply.  You  can  build  it  for  as  little  as 
$21.00,  complete;  even  less  if  you  shop  for 
bargains. 


PERHAPS  more  people  would  go  mobile  if  they 
didn't  have  to  drill  holes  in  their  cars,  bedeck 
them  with  special  antennas,  and  install  space- 
consuming  boxes  of  gear  that  require  something 
approaching  Hoover  Dam's  power  capacity.  The 
50-Mc.  band  is  a  big  help  in  these  problems. 
No  special  antenna  mounts  are  needed,  for  the 
standard  5-4-inch  broadcast  whip  is  a  respectable 
antenna  sj^stem  at  50  Mc.  And  the  nature  of 
6-meter  operation  is  such  that  a  moderate  amount 
of  power  works  out  surprisingly  well. 

A  simple  converter  can  be  built  that  will  give 
entirely  satisfactory  performance  on  6.  This 
article  will  describe  a  transmitter  that  should 
fill  the  bill  on  the  counts  of  simplicitj^,  small  size, 
low  total  cost  and  low  power  drain.  It  is  a  com- 
plete 6-meter  'phone  rig,  running  7  watts  input, 
built  in  a  3  X  4  X  5-inch  box.  Its  total  cost  is

tubes. 

As  may  be  seen  from  the  diagram.  Fig.  1,  the 
circuit  is  extremely  simple.  The  basis  for  this  lies 
in  the  use  of  50-Mc.  third-overtone  crystals. 
These  high-frequency  rocks  are  no  harder  to  use 
than  their  lower-frequency  brothers,  and  their 
relatively  high  price  is  offset  by  the  simplification

resulting  from  their  use.  (I  bought  mine  at  $1.50 
each,  but  figured  the  crystal  at  $7.00  in  the  cost 
estimate  above.)  Suitable  50-Mc.  crystals  can 
now  be  obtained  from  most  of  the  better  manu- 
facturers. 

Circuit  Details 

The  first  section  of  a  12BH7  is  operated  as  an 
overtone  oscillator  at  50  Mc.^  The  plate  voltage 
to  this  stage  is  held  down  by  a  large  resistor,  to 
help  reduce  the  crystal  current.  Developing  suffi- 
cient drive  for  the  final  does  not  seem  to  be  a 
problem.  Switching  for  two  crystals  is  provided, 
though  some  retuning  may  be  desirable  if  the  fre- 
quency shift  is  more  than  about   100  kc.   The 


No,  this  isn't  a  converter- — it's  a 
complete  50-Mc.  transmitter,  audio 
and  all.  It  runs  7  watts  input,  yet  it  is 
small  enough  for  steering-post  mount- 
ing.

second  section  of  the  12BH7  is  connected  as  a

Microphone  current  is  taken  from  across  the 
cathode  resistor  of  the  6BK5.  Since  the  filtering 
of  the  current  supply  is  not  perfect,  it  may  be 
necessary  to  reverse  the  leads  to  one  side  of  the 
microphone  transformer  to  eliminate  audio  os- 
cillation or  extreme  bassiness.  Arrangement  of 
parts  should  be  apparent  from  the  photographs. 

Tune-up 

Adjustment  is  best  begun  at  a  reduced  B-|- 
voltage,  200  volts  being  reasonable.  The  equip- 
ment used  includes  a  50-ma.  d.c.  meter,  a  re- 
ceiver for  si.x  meters  with  b.f.o.,  and  a  simple 
field-strength  meter.  A  nonmetallic  device  should 
be  used  to  tune  the  variable  condensers.  After  the 
initial  tune-up  only  the  field-strength  meter  is 
needed  to  touch  up  the  tuning. 

With  the  final  disabled  by  removing  its  plate 
voltage,  the  oscillator  is  checked  for  o]jeration 


by  listening  with  the  receiver.  With  the  b.f.o. 
turned  on,  neutralization  is  next  adjusted.  Tune 
the  final  tank  through  resonance  and  vary  the 
3-30-MMf-  neutralizing  capacitor  in  small  steps. 
Neutralization  exists  at  the  point  where  tuning 
the  final  through  resonance  has  practically  no 
effect  on  the  oscillator  frequency.  Plate  voltage 
can  now  be  reconnected,  through  the  milliam- 
meter.  The  final  plate  current  will  be  about  20  to 
25  ma.  when  the  plate  voltage  has  been  raised  to 
the  final  value  of  about  300  volts  and  the  antenna 
has  been  loaded  up. 

In  my  mobile  installation  plate  power  is  ob- 
tained from  a  receiver-tjpe  vibrator  supply 
which  is  hidden  in  the  glove  compartment.  No 
visible  holes  have  been  drilled  in  the  car. 

Generally,  I  can  work  a  60-watt  fixed  station 
as  far  as  it  is  readable  over  ignition  noise  from 
my  owTi  suppressed  engine.  Solid  communication 
over  a  10-  to  15-mile  range  may  be  obtained  in 
almost  all  locations,  even  with  cross-polarization 
and  the  low  power  used.

A  One-Element  Rotary  for  21  Mc. 

Utilizing  Readily  Available  Materials  in  a  Simple  Antenna 
BY  LEWIS  G.  McCOY.  WIICP 


IATELY,  more  and  more  amateurs  are  "discov- 
ering" the  15-meter  band.  Here  is  a  band 
-^  where  it  is  possible  to  make  long-distance 
contacts  with  low-power  transmitters.  Another 
feature  of  15  meters  is  that  antennas  can  be  much 
smaller  than  those  necessary  for  the  lower  fre- 
quency bands.  The  smaller  antenna  can  be  ro- 
tated to  take  advantage  of  the  directional  charac- 
teristics of  an  ordinary  half-wave  dipole. 

Before  discussing  the  actual  construction  of 
such  an  antenna,  let's  first  clear  up  an  erroneous 
impression  about  antennas  that  many  new- 
comers seem  to  have.  For  some  reason,  many 
amateurs  starting  in  the  hobby  get  the  idea  that 
a  horizontal  half-wave  antenna  has  no  direc- 
tional properties.  In  other  words,  they  believe 
that  when  power  is  fed  into  such  an  antenna,  the 
power  will  be  radiated  equally  well  in  all  direc- 
tions. This  is  a  completely  mistaken  concept.  A 
horizontal  half-wave  antenna  produces  maxi- 
mum radiation  broadside  to  the  radiating  ele- 
ment. The  least  amount  of  radiation  is  from  the 
ends  of  the  antenna.  Hence,  a  horizontal  half- 
wave  antenna  is  "bidirectional."  If  the  ends  of 
the  antenna  point  north  and  south,  maximum 
radiation  will  be  east  and  west.  To  obtain  the 
benefits  of  the  directional  properties  of  the  an- 
tenna, it  is  only  necessary  to  rotate  it  180  de- 
grees. Here  are  the  constructional  details  for  such 
an  antenna  that  can  be  built  for  less  than  $15,  com- 
plete with  mast,  wall  mounting  and  50  feet  of 
feed  line. 

'  A  half- wavelength  antenna  would  normally  be  fed  with 
72-ohm  cable,  since  the  antenna  offers  a  good  match  for  this 
impedance  value.  In  this  antenna  system,  the  shorter  ele- 
ments, plus  the  small  coil,  offer  a  good  match  for  52-ohm 
cable. 


•  Here  is  an  antenna  that  practically 
builds  itself.  Made  from  electrician's 
thin-wall  tubing,  a  material  sold  in  any 
electrical  supply  store,  its  main  feature 
is  that  no  cut-and-try  methods  are  in- 
volved in  its  construction.  Build  it  ac- 
cording to  the  directions  in  the  article, 
and  sit  back  and  watch  "solid"  QSOs 
pile  up. 


Construction 

The  antenna  is  made  from  two  pieces  of  H-inch 
diameter  electrical  thin-wall  steel  tubing  or  con- 
duit. This  tubing  is  readily  available  at  any  elec- 
tric supply  shop  and  sells  for  approximately 
seven  cents  a  foot.  It  comes  in  10-foot  lengths 
and,  while  20  feet  is  short  for  a  half-wave  antenna 
on  21  Mc,  with  loading  the  length  is  just  about 
right  for  52-ohm  feed  line.^  If  aluminum  tubing 
is  available,  it  can  be  used  in  place  of  the  conduit, 
and  the  antenna  will  be  lighter  in  weight.  How- 
ever, it  is  sometimes  difficult  to  obtain  aluminum, 
while  steel  thin-wall  conduit  is  available  in  any 
electrical  supply  house. 

As  can  be  seen  in  Fig.  1  and  the  photographs, 
the  two  pieces  of  tubing  are  supported  by  four 
stand-off  insulators  on  a  four  foot  long  2  by  2. 
The  coax  fitting  for  the  feed  line  was  mounted  on 
the  end  of  one  of  the  lengths  of  tubing.  A  mount- 
ing point  was  made  by  flattening  the  end  of  the 
tubing  for  a  length  of  about  1 14  inches.  The  tub- 
ing can  be  flattened  by  squeezing  it  in  a  vise  or 


This  view  shows  a  close-up

mountings.  Be  sure  that  the 
coil  doesn't  short  out  to  the 
outer  conductor  when  solder- 
ing the  coil  end  to  the  inner 
conductor  pin  on  the  coax 
fitting.

by  laying  the  end  of  the  tubing  on  a  hard  surface 
and  then  hammering  it  flat.  This  will  provide 
enough  space  to  accommodate  the  coax  fitting 
(Amphcnol  type  83-1 R).  A  ^-inch  hole  will  be 
needed  in  the  flat  section  to  clear  the  shell  of  the 
coax  fitting. 

The  coil,  L\,  is  made  from  Y^-\a.c\\  diameter 
copper  tubing.  It  consists  of  5  turns  spaced  34 
inch  apart  and  is  1  inch  inside  diameter.  The  coil 
is  connected  in  series  with  the  inner  conductor 
pin  on  the  coax  fitting  and  the  other  half  of  the 
antenna.  In  order  to  secure  a  good  connection  at 
the  coax  fitting,  the  coil  lead  should  be  wound 
around  the  inner-conductor  pin  and  soldered. 
The  other  end  of  the  coil  can  be  connected  with 
a  screw  and  nut. 

Mounting 

The  antenna  was  mounted  on  a  1-inch  floor 
flange  and  held  in  place  by  two  2-inch  bolts,  as 
shown  in  the  photograph.  The  floor  flange  was 
connected  to  a  12-foot  length  of  1-inch  pipe 
which  served  as  a  mast.  Television  antenna  wall 
mounts  were  used  to  support  the  mast.  In  the 
installation  shown,  19-inch  wall  mounts  were 
used  in  order  to  clear  the  eaves  of  the  house.  A 
2-inch  long  piece  of  l^^-inch  pipe  was  used  as  a 
sleeve,  and  it  was  clamped  in  the  U  bolt  on  the 
bottom  wall  mount.  A  34-inch  hole  was  drilled 
through  the  mast  pipe  approximately  6  inches 
from  the  bottom.  Then  a  13-^-inch  bolt  was 
slipped  through  the  hole  and  the  mast  was  then 
mounted  in  the  sleeve  on  the  bottom  wall 
mount.  The  bolt  acted  as  a  bearing  point  against 
the  top  of  the  sleeve. 

Another  34-inch  hole  was  drilled  through  the 
mast  about  three  feet  above  the  bottom  wall 
mount.  A  piece  of  34-inch  metal  rod,  six  inches 
long,  was  forced  through  the  hole  so  that  the  rod 
projected  on  each  side  of  the  mast.  To  turn  the 
mast,  a  piece  of  rope  was  attached  to  each  end  of 
the  rod  and  the  rope  was  brought  into  the  shack, 
so  that  the  antenna  could  be  rotated  by  the 


"arm-strong"  method.  Obviously,  one  could 
spend  more  money  for  a  "de  luxe"  version  and 
use  a  TV  antenna  rotator  and  mast. 

RG-8/U  52-ohm  coax  cable  was  used  to  feed 
the  antenna  shown.  For  power  inputs  up  to  100 
watts,  the  smaller  and  less  expensive  RG-58/U 
can  be  used.  However,  when  you  buy  RG-58/U, 
be  sure  that  the  line  is  made  by  a  reputable 
manufacturer    (such   as   Amphenol  or  Belden). 


The  antenna  mounted  against  the  side  of  the  house, 
using  TV  wall  mounts  for  holding  the  mast.  The  feed  line 
comes  out  of  the  bottom  of  the  mast  and  through  the 
wall  into  the  shack. 


January  1955

Some  of  the  line  made  for  TV  installations  is  of 
inferior  quality  and  is  likely  to  have  higher  losses. 
The  feed  line  was  fed  up  through  the  mast  pipe 
and  through  a  %-inch  hole  in  the  2  by  2.  An 
Amphenol  83-lSP  fitting  on  the  end  of  the  coax 
line  connects  to  the  female  fitting  on  the  antenna. 

Coupling  to  the  Transmitter 

It  may  be  found  that,  when  the  feed  line  is 
coupled  to  the  transmitter,  the  antenna  won't 
take  power.  Since  the  line  is  terminated  at  the 
antenna  in  its  characteristic  impedance  of  52 
ohms,  the  output  of  the  final  r.f.  amplifier  must 
be  adjusted  to  couple  into  a  52-ohm  load.  Where 
the  output  couphng  device  is  a  variable  link,  all 
that  ma.v  be  needed  is  the  correct  setting  of  the 
link.  If  the  link  is  fixed,  one  end  of  the  link  can  be 
grounded  to  the  transmitter  chassis  and  the  other 
end  of  the  link  connected  in  series  with  a  small 
variable  capacitor  to  the  inner  conductor  of  the 
feed  line.  The  outer  conductor  of  the  coax  is 
grounded  to  the  transmitter  chassis.  The  con- 
denser is  tuned  to  the  point  where  the  final  ampli- 
fier is  properly  loaded.  Such  a  system  is  shown  in 
Fig.  2.  Incidentally,  this  is  the  type  of  system 
that  could  be  used  with  the  Heathkit  transmitter. 


Fig.  2  —  The  variable  coupling  condenser,  Ci, 
described  in  the  text,  can  be  connected  as  at  (A)  or 
(B),  depending  on  which  is  more  convenient  for  a  par- 
ticular transmitter.  The  condenser  can  be  a  receiving 
type  of  50  to  100  nfii.  capacity. 


For  transmitters  having  a  pi-network  output 
circuit,  it  is  merely  a  matter  of  adjusting  the  net- 
work to  the  point  where  the  amplifier  is  properly 
loaded. 

In  the  event  operation  on  15  meters  is  in  an 
area  where  one  may  have  to  contend  with  TVI, 
it  may  be  necessary  to  use  a  low-pass  filter  to  at- 
tenuate any  harmonics  likely  to  cause  trouble.  A 
simple  filter  was  described  in  a  recent  issue  of 
Qgf  2  "pjjg  filter  is  merely  inserted  in  series  with 
the  coax  feedline.  This  should  take  care  of  har- 
monic TVI  problems.

Several  different  tests  were  made  with  the  an- 
tenna including  on-the-air  checks  with  U.  S.  and

foreign  stations.  The  standing-wave  ratio  was 
carefully  checked  and  at  no  point  in  the  entire 
21-Mc.  band  did  the  ratio  exceed  1.3  to  1. 

On  the  first  CQ  using  the  antenna,  KP4WI 
answered  and  kindly  consented  to  check  the 
signal  while  the  dipole  was  rotated.  With  the  an- 
tenna broadside  to  him,  his  S-meter  reading  was 
10  db.  over  S9.  When  the  end  of  the  antenna  was 
pointed  in  his  direction,  the  reading  dropped  to 
SI  to  S3.  Practically  identical  performance  re- 
ports were  received  from  W7SFK  in  Montana, 
from  W5KC  in  Louisiana,  and  from  DL2WW  in 
Germany. 

On  reception,  the  variation  from  broadside  to 
end  was  not  as  great  as  with  transmitting  re- 
ports. However,  in  many  cases  it  was  enough  to 
make  the  difference  between  hearing  a  signal  and 
not  hearing  one. 

The  simplicity  of  the  antenna  and  the  low  cost, 
together  with  the  improved  performance  over  a 
fixed  antenna,  make  it  a  worth-while  project  for 
an  amateur  interested  in  15-meter  operation.  At 
the  time  of  this  writing,  an  0Q5  station  in  the 
Belgian  Congo  was  heard  on  15  meters  working 
Novice  stations.  Who  will  be  the  first  Novice

Grounded-Grid  and  the  304-TH 

Utilizing  "200- Watt"  Rigs  for  Driving 

BY  THOMAS  P.  LEARY,*  W0VTP 


ONE  thing  that  bothers  most  of  us  about  de- 
signing and  building  a  final  amplifier  is 
neutralization.  This  old  dragon  is  with  us 
in  all  conventional  triode  circuits,  and  a  great 
many  tetrodes  also  require  it.  But,  with  the  right 
tube,  the  grounded-grid  circuit  will  put  the  neu- 
tralizing condenser  and  split-stator  tank  ba(;k  in 
the  junk  box. 

Still,  we  can't  get  something  for  nothing  and 
grounded-grid  operation  requires  four  to  six 
times  the  driving  power.  If  we  haven't  already 
lost  you,  let's  see  what  can  be  done  with  this 
arrangement. 

Only  the  normal  drive  requirement  of  the  tube 
is  dissipated  in  the  grid  circuit;  the  remaining 
power  passes  through  it  and  is  added  to  the  total 
power  output.  The  filament,  or  input,  circuit  has 
a  very  low  impedance,  permitting  the  amplifier 
to  operate  as  a  Class  B  linear  without  swamping 
resistors. 

Many  amateurs  own  a  Collins  32-V,  a  Johnson 
Viking  or  a  homebrew  rig  with  an  output  in  the 
vicinity  of  135  watts  or  more.  When  switching  to 
higher  power  it  seems  a  shame  to  dispose  of  this 
equipment,  and  somewhat  ridiculous  to  use  it  to 
drive  a  final  requiring  only  a  few  watts  for  the 
purpose.  But  such  an  e.xciter  can  be  used  without 
modification  to  drive  a  tube  like  the  304-TH  to 
a  kilowatt  on  c.w.  or  750  watts  on  'phone.  With 
the  same  plate  efficiency,  the  grounded-grid  stage

can  put  out  more  power  than  a  conventional 
amplifier  since  additional  r.f.  is  obtained  from  the 
driver.  And,  because  we  have  no  need  for  neutral- 
izing, a  pi-section  output  is  a  simple  addition  to 
the  circuit.  In  Class  B  linear  service  only  about 
25  watts  of  drive  is  required  which  results  in  200 
watts  of  a.m.  carrier.  With  high  level,  100  per 
cent  plate  modulation  cannot  be  obtained  by 
modulating  the  final  alone,  since  a  fraction  of  the 
outjjut  originates  in  the  driver,  but  the  extra 
carrier  is  useful  in  getting  through  the  QIIM. 

The  main  requirement  for  a  tube  to  be  oper- 
ated in  this  manner  is  a  low  plate-to-filament 
capacitj'.  The  304-TH  has  a  capacity  of  about 
0.7  /x/uf.  plus  the  added  advantage  of  an  internal 
shield  connected  to  the  grid.  The  grid,  which  is 
grounded  for  r.f.  through  a  by-pass  condenser, 
shields  the  input  and  output  circuits  from  each 
other  in  much  the  same  manner  as  the  screen 
grid  in  a  tetrode.  The  driving  power  required 
depends  to  a  great  extent  on  bias  and  increases 
as  the  bias  goes  up.  At  cut-off  (  —  135  volts  with 
2500  volts  on  the  plate)  the  304-TH  can  be  loaded 
to  draw  400  plate  milliamperes  with  135  watts 
of  drive  and  40  ma.  of  grid  current.  Under  these 


January  1955 


conditions,  using  a  bank  of  light  bulbs  and  a  light 
meter,  800  watts  output  was  measured.  Since  at 
least  twice  cut-off  bias  is  desirable  for  good 
linearity  with  plate  modulation,  about  —250 
volts  should  be  used  for  'phone  operation.  One 
hundred  watts  will  then  drive  the  tube  to  750 
watts  input,  still  with  40  ma.  of  grid  current. 
However,  it  was  found  possible  with  this  circuit 
to  modulate  the  final  at  a  kilowatt  input  with 
cut-off  bias  without  any  splatter  or  serious 
deterioration  of  quality. 

A  304-TL  may  also  be  used  but  drive  require- 
ments will  be  increased  about  30  per  cent.  As  an 
example,  if  a  200-watt  exciter  is  available,  the 
304-TL,  with  -380  volts  bias  and  3000  volts  on 
the  plate,  can  produce  more  than  a  kilowatt  out- 
put with  input  at  the  legal  hmit.^  Both  types  can 
still  be  found  in  surplus  stocks  for  less  than 
$10.00. 


'  The  power  rating  of  a  grounded-grid  amplifier  is  not 
covered  explicitly  in  the  current  amateur  regulations,  but 
FCC's  interpretation  is  that  the  plate  input  to  the  "final 
stage"  shall  be  considered  to  be  the  sum  of  the  plate  inputs 
to  all  stages  contributing  output  power  to  the  antenna.

Circuit 

As  can  be  seen  from  Fig.  1,  drive  is  injected 
into  the  filament-grid  circuit  and  the  power  out- 
put is  taken  between  grid  and  plate.  Power 
sensitivity  is  very  low  and  if  plate-filament  feed- 
back can  be  kept  to  a  minimum  no  neutralization 
is  required.  This  means  that  the  input  circuit 
must  carry  the  regular  filament  current  in  addi- 
tion to  r.f.,  and  ordinary  bandswitching  of  the 
input  is  not  desirable.  To  conserve  space,  the 
amplifier  to  be  described  was  designed  for  40,  20, 
15  and  10  meters  onl3^  The  main  filament  coil  (a 
dual  winding)  is  used  alone  for  40  meters  and  the 
other  coils  are  switched  in  parallel  to  cover  the 
higher  frequencies.  The  52-ohm  input  link  is 
coupled  to  the  filament  coil  only,  and  need  not  be 
varied  over  the  different  bands;  however,  some 
system  of  changing  the  coupling  between  the 
driver  tank  and  coax  line  should  be  provided.  The 
internal  antenna  coupler  in  transmitters  like  the 
Collins,  or  a  pi-section  in  the  driver  output,  is 
entirely  satisfactory. 

The  amplifier  output  circuit  will  match  a  52- 
ohm  line.  A  9000-volt  tank  condenser  was  found

is  used  as  the  bleeder  on  a  bias  supply  delivering

supply  must  be  unusually  husky  because  of  the 
low  value  of  grid-leak  resistance  recjuired.  The 
bias  supply  circuit  used  is  shown  in  Fig.  2.  The

Mechanical 

This  amplifier  is  the  result  of  considerable 
sweat  and  experimentation  and  the  builder  may 
depart  from  the  illustrated  component  layout  at 
his  own  risk.  Contrary  to  some  published  informa- 
tion, grounded-grid  does  not  eliminate  parasitics 
with  these  tubes  and  great  care  must  be  taken  to 
keep  plate-to-tank-condenser  and  filament-to- 
input-condenser  leads  short.  The  parasitic  chokes 
and  resistors  should  make  up  most  of  these  leads. 
Complete  shielding,  without  any  inductive  cou- 
pling, must  be  maintained  between  input  and 
output  circuits  to  prevent  oscillation  on  the 
operating  frequency. 

The  amplifier  is  mounted  on  a  10  X  17  X  4- 
inch  aluminum  chassis.  The  filament  components 
are  located  on  the  under  side  at  the  right.  A 
dividing  shield  and  ventilated  bottom  cover  are 
placed  over  this  half,  while  the  left  under  side  is 
used  to  mount  the  filament  transformer  and 
meters.  A  2-Ji  e-ii^ch  hole  is  cut  near  the  front  of 
the  chassis,  with  its  center  7  inches  from  the 
right-hand  edge,  and  the  304-TH  is  submounted 
so  that  the  internal  shield  is  level  with  the  top  of

January  1955 


•  A  practical  grounded-grid  circuit  using 
a  high-power  tube  popular  because  of 
its  low  price  in  surplus.  The  amplifier 
incorporates  the  lessons  learned  in  ear- 
lier attempts  to  make  the  304  behave 
in  a  bandswitching  grounded-grid  ar- 
rangement covering  7  to  30  Mc. 


the  chassis.  The  tank  condenser  is  placed  just  to 
the  left  of  the  tube  and  mounted  upside  down  to 
obtain  a  short  lead  from  the  plate  cap  to  the 
center  of  the  stator.  The  R175A  choke  is  placed 
horizontally  with  its  top  near  the  tube  cap.  The 
tank  coil  is  mounted  to  the  left  of  the  condenser 
with  the  "cold"  end  toward  the  front.  The  coax 
socket,  loading  condensers  and  switch  are  located 
to  the  rear  between  the  coil  and  condenser. 

Some  kind  of  blower  is  a  necessity  with  such 
compact  design  since  the  304TH  dissipates  130 
watts  continuously  from  the  filament  and  a 
couple  of  hundred  watts  more  when  in  operation. 
Plenty  of  space  is  available  on  the  right  side 
above  chassis  for  the  blower,  and  air  can  be  drawn 
in  through  the  front  panel.  The  panel  is  alumi- 
num, IOJ2  hy  18:>i6  inches,  and  the  whole  thing 
will  fit  in  the  top  section  of  a  Bud  Junior  Cabinet 
Rack  (RC-1947A)  which  is  21  Ji  by  193^  by  10^ 
inches.  The  lower  section  needs  no  chassis  and  all 
power  supply  equipment,  except  the  plate  trans- 
former, can  be  fitted  in  if  the  arrangement  is 
carefully  worked  out.  The  plate-transformer  ter- 
minals may  be  covered  with  a  steel  chassis  of  the 
proper  size  and  high  voltage  led  to  the  rectifiers 
through  RG-8/U  cable,  with  the  shield  grounded 
as  a  safety  measure.  The  transformer  can  then  be 
set  on  the  floor  under  the  operating  desk.  The 
center  tap  of  the  high-voltage  winding  can  be 
connected  to  the  plate  milliammeter  through 
ordinary  shielded  wire. 

A  small  shield  was  found  necessary  above 
chassis  between  the  304-TH  and  the  tank  con- 
denser, to  eliminate  capacitive  coupling  with  the 
filament. 

The  main  filament  coil  is  mounted  horizon- 
tally, lengthwise  with  the  chassis,  with  the  "hot" 
end  just  behind  the  base  of  the  tube.  To  the  right 
of  the  tube,  under  chassis,  is  the  filament  variable 
condenser.  The  20-,  15-,  and  10-meter  coils  are 
grouped  compactly  around  the  coil  switch  and 


the  ends  soldered  directly  to  the  tabs  on  the 
switch.  The  opposite  ends  of  all  three  are  soldered 
together  and  connected  by  a  short  lead  to  ground. 

The  filament  by-pass  condensers  are  connected 
directly  across  the  socket  terminals.  The  parasitic 
choke  and  resistor  are  fastened  between  the 
right-hand  forward  socket  terminal  and  the  front 
stator  connection  of  the  filament  variable 
condenser. 

The  filament  transformer  is  located  under  the 
chassis  in  the  left  rear  corner.  The  transformer 
specified  is  somewhat  overloaded  for  this  use  and 
runs  hot  but  it  will  deliver  the  voltage  if  the 
11-volt  primary  tap  is  used. 

We  have  the  old-fashioned  notion  that  nothing 
can  beat  air-wound  copper  tubing  for  a  low-loss 
coil.  There  was  no  room  in  this  set-up  for  a  con- 
ventional high-power  switch,  so  we  hit  on  the 
idea  of  using  fuse  clips  fastened  directly  to  the 
tank  coil.  The  coil  itself  is  193^  turns  of  ^fe-inch 
copper  tubing,  2  inches  in  dimeter  and  7K 
inches  long.  First,  close-wind  the  coil  and  spread 
it  to  6  inches.  Then  spread  the  rear  5}^  turns 
until  the  whole  thing  is  73^  inches  long.  The  coil 
is  supported  on  %  by  2J^-inch  stand-offs  and 
soldered  to  screws  in  the  tops  of  the  three  insula- 
tors at  the  3rd,  8th  and  18th  turns  (approxi- 
mately) counting  from  the  rear  of  the  chassis. 
The  fuse  clips  are  soldered  or  fastened  to  holes  in 
the  tubing  with  small  screws,  in  line  at  33^,  5J^ 
and  83^  turns,  also  counting  from  the  rear.  A 
piece  of  3i-inch  brass  rod,  with  the  point  rounded, 
acts  as  a  shorting  bar  between  the  clips  and  is 
connected  to  a  piece  of  3^-inch  fiber  rod  with  a 
shaft  coupling  so  that  it  can  be  slid  in  and  out 
from  the  front  panel.  A  ^f  e-inch  copper  tubing 
lead  runs  from  the  front  of  the  coil  to  the  rear 
coax  connector,  and  another  fuse  clip  is  fastened 
to  this  lead  with  a  short  piece  of  tubing  so  that  it 
always  grips  the  shorting  bar  to  complete  the 
connection.  The  whole  assembly  can  be  made 
quite  rigid  and  the  fuse  clips  make  a  positive, 
self-cleaning  connection.  Different  points  can  be 
scribed  on  the  fiber  rod  to  indicate  the  correct 
setting  for  each  band. 

Heat-radiating  connectors  should  be  used  on 
the  grid  and  plate  leads  of  the  304-TH.  The  grid 
by-pass  condenser  to  ground  should  have  prac- 
tically no  leads. 

The  parasitic  resistors  are  of  the  Globar  type, 
available  from  General  Electric  TV  parts  dealers. 
They  are  about  i3'lr,  inch  long,  ^lo  inch  in  dia- 


meter and  come  two  to  a  package.  The  plate  circuit 
parasitic  choke  is  23^  turns,  3^-inch  diameter 
with  the  resistor  paralleled  across  it  with  very 
short  leads.  The  filament  circuit  parasitic  choke 
consists  of  two  turns  wound  directly  on  the  re- 
sistor. Both  are  wound  with  No.  12  wire. 

Tuning  and  Operation 

Since  the  filament  and  plate  circuits  are  essen- 
tially in  series,  some  differences  may  be  expected 
in  tuning  as  compared  with  an  ordinary  ampli- 
fier. Full  excitation  should  not  be  applied  without 
plate  voltage  on,  since  the  rated  grid  dissipation 
will  be  exceeded  and  tube  damage  can  result. 
Some  way  of  reducing  driving  power,  such  as 
switching  resistance  in  series  with  the  plate  sup- 
ply primary  of  the  exciter,  should  be  provided. 

First  apply  reduced  excitation  with  plate  volt- 
age off.  Do  not  exceed  about  60  ma.  of  grid  cur- 
rent; it  will  peak  at  the  resonance  point  of  the 
input  condenser.  Then  resonate  the  plate  con- 
denser, which  will  be  indicated  by  an  increase  in 
grid  current.  It  will  be  noticed  that  some  plate 
current  will  flow  even  without  plate  voltage,  and 
a  dip  will  be  found  at  resonance.  Now  apply  re- 
duced plate  voltage  through  a  series  resistance, 
like  a  500-watt  photo-flood  bulb,  in  the  primary 
of  the  plate  transformer.  With  bias  reduced  below 
cut-off,  make  the  usual  checks  for  parasitics  with 
different  settings  of  the  tuning  condensers.  Then 
apply  full  voltage.  Grid  current  will  probably  dis- 
appear, so  increase  excitation  and  make  addi- 
tional adjustments  for  maximum  grid  and  mini- 
mum plate  current.  Loading  can  be  controlled 
with  the  variable  loading  condensers.  Keep  an 
eye  on  the  plate  current  drawn  by  the  driver 
stage  while  making  adjustments  in  the  final,  as 
coupling  may  have  to  be  reduced  to  keep  the 
driver  tube  from  exceeding  its  ratings.  Bias  may 
be  reduced  to  near  cut-off  for  c.w.  in  order  to 
obtain  at  least  40  grid  milliamperes  at  a  kilowatt 
input;  however,  the  more  bias  the  better  the  plate 
efficiency.  With  practice,  the  stage  may  be  moved 
around  the  band  very  quickly;  the  filament  cir- 
cuit tuning  is  fairly  broad  and  requires  only 
occasional  adjustment. 

For  Class  B  linear  amplification  of  an  a.m. 
signal,  maximum  input  is  500  watts.  Reduce  the 
drive  to  about  25  watts  or  until  no  grid  current 
flows  without  modulation.  With  modulation  it 
should  rise  to  about  20  ma.  in  peaks  with  bias

General  Techniques  of  10-Meter  Mobile 
Noise  Reduction 

Waveiraps  as  Ignition  Suppressors 

BY  TALMADGE  R.  ENGLAND,*  W4MJJ 


•  In  this  article,  W4MJJ  discusses  the 
use  of  tuned  wavetraps  in  suppressing 
electrical  noise  in  lO-meter  mobile  in- 
stallations. 


MOBILE  OPERATION  of  amateur  stations  is 
ever  becoming  more  popular,  and  espe- 
cially will  this  be  true  if  ten  meters  finally 
does  open  wide  next  year  (it's  always  next  year!). 
What  follows  is  intended  to  give  the  would-be 
mobileer  a  fundamental  insight  into  the  cause  of 
the  biggest  headache  of  mobile  operation  —  noise. 
Compared  to  the  elimination  of  noise,  especially 
in  the  ten-meter  band,  the  actual  installation  of 
the  equipment  is  comparatively  easy. 

Now  every  ham  knows  that  whenever  a  spark 
occurs  some  r.f.  noise  is  generated.  In  fact,  it 
is  not  at  all  necessary  that  there  be  a  spark 
—  merely  a  surge  of  current.  The  current  surge 
induces  transients  in  the  associated  wiring  or, 
what  amounts  to  the  same  thing,  it  "shock"- 
excites  the  inductance  and  capacitance  of  the 
wiring  into  a  damped  oscillation.  Due  to  the 
random  distribution  of  these  two  parameters,  the 
oscillations  occur  at  many  frequencies.  It  is 
probably  unnecessary  to  point  out  that  the 
car's  ignition  system  is  the  biggest  noise  producer, 
with  the  generator  and  regulator  trailing.  In- 
deed, if  ten-meter  operation  is  contemplated,  you 
had  best  decide  that  complete  elimination  is 
impossible,  and  purchase  or  build  a  good  noise 
limiter  at  the  outset.  However,  the  limiter,  used 
in  conjunction  with  standard  methods  of  sup- 
pressing noise  in  its  various  and  sundrj^  spots, 
and  traps  in  the  ignition  system  (to  be  described), 
will  reduce  the  interference  to  a  most  tolerable 
level. 

While  standard  methods  of  noise  suppression 
are  aptly  detailed  in  late  editions  of  The  Radio 
Amateur's  Handbook  and  will  not  be  repeated 
here,  it  will  be  interesting  to  enumerate  the 
basic  methods  in  a  general  manner.  By  keeping 
in  mind  the  simple  idea  of  what  transients  are 
and  how  they  arise,  the  following  seven  methods 
of  reducing  or  eliminating  them  are  evidently 
fundamental:  (1)  elimination  of  L  and /or  C; 
evidently,  no  oscillatory  transients  would  then 
be  possible  —  but  neither  is  the  method.  (2) 
Elimination  of  the  spark.  This  is  not  so  impos- 
sible as  it  sounds,  for  that  is  precisely  what  we 
do  when  graphite  grease  is  used  in  the  wheel 

*  %  WMIK,  P.  O.  Box  698,  Middlesboro,  Ky. 


bearings  to  eliminate  wheel  static.  (3)  Damping 
the  oscillation.  This  is  the  usual  method  of  reduc- 
ing ignition  interference;  i.e.,  by  installing  re- 
sistors in  the  wiring.  Unfortunately,  this  method 
is  not  applicable  to  other  parts  of  the  electrical 
system.  (It  is  interesting  that  from  a  theoretical 
viewpoint  there  is  a  critical  value  of  damping 
resistance  beyond  which  no  oscillatory  transients 
are  produced,  but  the  value  is  too  large  to  be  of 
practical  use.)  (4)  Shielding  of  wiring.  (5)  Ground- 
ing of  such  possible  radiating  elements  as  the 
tail  pipe.  (6)  Bj'-passing  of  the  various  electrical

components  of  the  car,  such  as  dome  light,  gas 
gauge,  etc.  It  should  be  kept  in  mind  that  a 
car's  electrical  system,  being  of  low  voltage, 
is  a  low-impedance  system.  By-passing  is,  there- 
fore, not  so  effective  as  might  be  e.xpected.  (7) 
Rejection  by  the  use  of  tuned  traps  or  chokes.     ^ 

The  last  method  has  been  too  much  neglected. 
Although  some  amateurs  do  use  tuned  traps  in 
the  generator  lead,  no  one  seems  to  have  tried 
them  in  the  ignition  wiring.  The  author  installed 
traps  on  each  plug,  and  inserted  similar  traps 
in  the  main  tower  of  the  distributor,  and  at  the 
generator  and  the  regulator.  The  generator  and 
regulator  traps  practically  eliminate  noise  from 
these  two  sources,  whereas  by-passing  will  not. 
Noise  rejection  in  the  ignition  system  is  at  least 
as  good  as  that  obtained  with  resistor  suppressors. 
But  where  ignition  interference  is  concerned,  the

Using  the  6524  Dual  Tetrode  on  432  Mc. 

A  Tripler- Amplifier  To  Follow  Your  Present  2-Meter  Rig

THE  fellow  who  wanted  to  put  more  than 
a  couple  of  watts  on  420  Mc.  had  little  in 
the  w^ay  of  tube  choice  until  recently.  There 
were  only  a  few^  transmitting  tubes  on  the  market 
that  would  do  the  job,  and  prices  for  these 
began  at  around  $25.00  each.  Introduction  of

ing are  employed. 


to  375  volts,  one  6524  as  a  tripler  will  drive 
another  as  a  straight-through  amplifier.  Output 
from  the  tripler  stage  can  be  as  much  as  8.5 
watts,  and  the  amplifier  will  deliver  up  to  20 
watts.  These  ratings  are  for  470  Mc,  so  some 
leeway  is  left  for  the  amateur  in  getting  efficient 
operation  at  the  third  multiple  of  his  2-meter 
frequency. 

The  transmitter  sliown  here  is  a  modernized 
version  of  the  dual  tetrode  rig  that  has  appeared 
in  the  Handbook  for  some  years.  It  can  be  driven 
with  a  2E26  amplifier  on  144  Mc.  readily,  as 
the  driver  power  output  need  be  no  more  than 
4  to  0  watts  at  144  Mc.  Output  on  432  Mc, 
under  plate-modulation  conditions,  is  a  good 
12  watts;  enough  to  make  quite  a  respectable 
signal.  On  f.m.  or  cw\,  it  can  be  boosted  to  the 
20-watt  ICAS  operating  conditions. 

Construction 

It  will  be  noted  that  provision  is  made  for 
enclosing  the  tubes  and  tank  circuits  completely. 
The  enclosure  serves  two  purposes:  it  provides 
a  path  for  circulation  of  cooling  air,  and  holds 
down  radiation  from  the  tank  circuits.  The 
latter    consideration    is    important    in    getting 

'  ••  World  Above  .JO  Mc,"  QST.  October,  1951,  p.   13G. 


power  into  the  transmission  line,  and  of  course 
the  shielding  is  an  aid  to  TVI  prevention. 

The  main  chassis  is  fitted  with  a  bottom  cover. 
Air  from  the  fan  mounted  on  the  rear  wall  is 
circulated  up  around  the  tripler  tube,  at  the 
left,  and  through  J^-inch  holes  below  the  ampli- 
fier tube.  Holes  in  the  top  cover  are  the  only 
means  for  this  air  to  escape,  and  thus  the  cooling 
flow  is  concentrated  where  it  will  do  the  most 
good.  The  number  of  holes  in  the  top  cover, 
and  in  the  chassis  under  the  amplifier  tube, 
can  be  varied  until  an  equal  flow  of  air  appears 
to  be  coming  through  the  two  top  sets  of  holes. 
This   can   be   checked   readily   by   noting   how 


briskly  a  sheet  of  paper  rises  from  either  set 
of  holes  when  the  fan  is  started.  This  check 
should,  of  course,  be  made  with  the  bottom 
plate  in  place. 

The  fan  shown  provides  a  flow  of  17  cubic 
feet  per  minute,  more  than  adequate  for  the 
job,  so  no  great  care  was  taken  to  stop  small 
air  leaks.  Where  a  smaller  fan  is  used,  all  air 
holes  should  be  plugged.  Small  holes  and  cracks 
can  be  sealed  with  household  cement,  and  the 
meter  jacks  should  be  plugged  in  this  case. 

The  tripler  tube  is  mounted  vertically,  at 
the  left,  with  its  socket  13^  inches  below 
the  chassis.  There  is  just  room  under  the  socket 
for  the  self-resonant  input  circuit,  L2.  The 
amplifier  tube  is  horizontal,  with  its  socket 
mounted  in  back  of  a  plate  that  is  8  inches 
from  the  left  edge  of  the  3  X  4  X  17-inch 
aluminum  chassis.  The  shielding  enclosure  is 
3}/4  inches  wide  by  3}^  inches  high 

Half-wave  lines  are  used  in  all  432-Mc. 
circuits.  The  grid  circuit  of  the  amplifier  is  capa- 
citively  coupled  to  the  tripler  plate  line,  the  two 
overlapping  about  Ij^  inches.  The  spacing 
between  them  must  be  adjusted  carefully  for 
maximum  grid  drive.  Plate  voltage  is  fed  to 
the  lines  through  small  resistors.  These  should

connected  at  the  tube  socket. 

Some  interesting  "bugs"  were  encountered 
in  the  development  of  this  layout.  A  haj^vire  test 
set-up  was  made  to  check  the  operation  of  the 
new  tubes.  They  worked  fine,  so  a  "final"  form 
was  evolved  as  shown,  e.xcept  for  the  variable 
capacitors  used  for  tuning  the  plate  lines.  At 
first  we  used  a  split^stator  unit  equipped  with 
metal  end-plates  that  grounded  the  rotors. 
With  these  the  tripler  gave  more  output  on 
the  second  harmonic  than  on  the  third.  When 
the  rotor  was  ungrounded  there  was  a  consid- 
erable improvement.  As  this  particular  capacitor 
could  not  be  mounted  conveniently  without 
grounding  the  rotor,  we  next  tried  the  capacitors

specified.  These  have  metal  mounting  brackets, 
but  they  are  not  connected  electrically  to  the 
rotor  shaft.  Even  with  these  units,  using  the 
metal  brackets  grounded  to  the  chassis  threw 
the  tank  circuits  out  of  balance,  so  it  was  nec- 
essary to  mount  the  capacitors  up  on  edge, 
on  polystyrene  plates.  With  this  arrangement 
there  was  practically  no  second  harmonic  in 
evidence  in  the  tripler  tank  circuit,  and  both 
it  and  the  amplifier  circuit  tuned  normally 
and  showed  good  efficiencj'. 

Testing 

The  tripler-amplifier  is  designed  to  operate  in 
conjunction  with  a  144-Mc.  transmitter  such 
as  the  2E26  rig  shown  in  October  QSTr  A  plate 
supply  of  300  volts  at  200  ma.  is  needed.  Apply

coupling  between  Li  and  L2  for  maximum  tripler 
grid  current.  This  should  be  about  3  ma. 

Ne.xt  apply  plate  and  screen  voltage  to  the 
tripler  and  tune  Ci  for  ma.ximum  grid  current 
in  the  amplifier,  with  no  plate  or  screen  voltage 
to  the  latter.  Adjust  the  position  of  the  grid 
lines  with  respect  to  the  plate  circuit,  readjusting 
Ci  whenever  a  change  is  made,  until  at  least 
4  ma.  grid  current  is  obtained. 

Now  connect  a  lamp  load  across  the  output 
terminal,  J2.  Ordinary  house  lamps  are  not 
suitable.  A  fair  load  can  be  made  by  connecting 
6  or  more  blue-bead  pilot  lamps  in  parallel. 
This  can  be  done  by  wrapping  a  3€-inch  copper 
strap  around  the  brass  bases  and  soldering  them 
all  together.  Then  another  strap  should  be 
soldered  to  the  lead  terminals.  Apply  plate  and 
screen  voltage  and  tune  C2  for  maximum  lamp 
brilliance.  It  should  be  possible  to  develop  a 
very  bright  glow  in  the  6-lamp  load  with  a 
plate  current  of  about   100  ma.   at  300  volts. 

Cut  drive  very  briefly  to  check  for  oscillation 
in  the  final  stage.  Grid  current  should  drop  to 
zero.  The  rig  is  then  ready  for  use.  The  screen 
and  grid  resistors  shown  are  for  operation  with 
plate  modulation.  Somewhat  more  output 
and  input  can  be  run  if  the  screen  or  grid  resist- 
ance is  decreased  slightly,  but  this  should  be 
done  only  when  the  rig  is  to  be  used  for  f.m.  or 
c.w.  service. 

Operating  conditions  are  about  as  follows: 
tripler  grid  current  —  2  to  3  ma.;  amplifier 
grid  current  —  3  to  4  ma. ;  tripler  plate  and 
screen  current  —  90  ma. ;  amplifier  plate  and 
screen  current — 110  ma.;  output  —  12  watts. 

In  choosing  the  operating  frequency  it  is 
well  to  bear  in  mind  that  nearly  all  work  being 
done  in  the  420-Mc.  band  involves  tripling 
from  commonly-used  frequencies  in  the  2-meter 
band.  By  mutual  agreement,  to  make  it  a  rela- 
tively simple  matter  for  stations  using  narrow- 
band techniques  to  find  one  another,  stabilized 
transmitters  are  kept  between  432  and  436  Mc. 

This  tripler-amplifier  was  built  around  the 
6524  tetrodes,  but  the  same  general  construction 
can  be  used  with  other  dual  tetrodes  such  as 
the  6252  and  5894A  by  Amperex  and  the  832A. 
With  the  6252,  operating  conditions  will  be 
quite  similar  to  those  given  above.  With  the 
5894A  (9903),  up  to  40  watts  output  can   be 


obtained  on  c.w.  or  f.m.,  and  25  to  30  watts 
with  plate  modulation.  The  832A  will  dehver 
only  about  5  watts.  The  pin  connections  given 
in    the    schematic    diagram    are    for    the    6524. 


WWV-WWVH  SCHEDULES 

Tj^OR  the  benefit  of  amateurs  and  other  interested 
-T  groups,  the  National  Bureau  of  Standards 
maintains  a  service  of  technical  radio  broadcasts 
over  WWV,  Beltsville,  Md.,  and  WWVH,  Maui, 
Territory  of  Hawaii. 

The  services  from  WWV  include  (1)  standard 
radio  frequencies  of  2.5,  5,  10,  15,  20  and  25  Mc, 
(2)  time  announcements  at  5-minute  intervals  by 
voice  and  International  Morse  code,  (3)  standard 
time  intervals  of  1  second,  and  1,  4  and  5  minutes, 
(4)  standard  audio  frequencies  of  440  cycles  (the 
standard  musical  pitch  A  above  middle  C)  and 
600  cycles,  (5)  radio  propagation  disturbance 
warnings  by  International  Morse  code  consisting 
of  the  letters  W,  U  or  N,  together  with  digits 
from  1  through  9,  indicating  present  North 
Atlantic  path  conditions  and  conditions  to  be 
anticipated.  (See  Measurements  chapter  of  recent 
Handbooks  for  details  on  forecast  symbols.) 

The  audio  frequencies  are  interrupted  at  pre- 
cisely one  minute  before  the  hour  and  are  re- 
sumed precisely  on  the  hour  and  each  five  minutes 
therefater.  Code  announcements  are  in  GMT  us- 
ing the  24-hour  system  beginning  with  0000  at 
midnight;  voice  announcements  are  in  EST.  The 
audio  frequencies  are  transmitted  alternately: 
The  600-cycle  tone  starts  precisely  on  the  hour 
and  every  10  minutes  thereafter,  continuing  for  4 
minutes;  the  440-cycle  tone  starts  precisely  five 
minutes  after  the  hour  and  every  10  minutes 
thereafter,  continuing  for  4  minutes.  Each  carrier 
is  modulated  by  a  seconds  pulse,  heard  as  a  faint 
clock-like  tick;  the  pulse  at  the  beginning  of  the 
last  second  of  each  minute  is  omitted.

Three  Stormy  Sisters 

Part  I —  Carol  and  Edna 


BY  GEORGE  HART,  WINJM 


•  So  many  reports  were  received  on 
amateur  emergency  activities  during 
the  three  hurricanes  that  it  became  im- 
possible to  tell  a  complete  story  in  alloM'- 
able  QST  space  for  a  single  issue.  We'll 
tell  you  about  Hazel  in  a  future  QST. 


TROPICAL  HURRICANES  are  fickle  and  unpre- 
dictable things.  Perhaps  that's  why  they 
are  given  women's  names.  Not  since  1944 
has  the  Northeast  received  a  visitation  from  a 
tropical  storm,  but  this  year,  one  decade  later, 
as  if  to  make  up  for  past  omissions,  three  scream- 
ing hurricanes,  spawned  in  the  Caribbean,  made 
their  destructive  way  up  the  Atlantic  Coast. 
First  Carol  curved  in  out  of  the  Atlantic,  brushed 
Hatteras,  howled  up  the  Western  Atlantic  to 
hit  the  end  of  Long  Island  and  deliver  a  smashing 
blow  to  Connecticut,  Rhode  Island  and  Eastern 
Massachusetts  as  she  failed  to  curve  out  to  sea 
as  expected.  Two  weeks  later  Edna  started 
north,  maintaining  a  more  easterly  course  and 
wreaking  most  of  her  havoc  on  Nantucket, 
Cape  Cod,  the  Maine  coast  and  the  Canadian 
Maritime  Provinces. 

But  Old  Dame  Nature  was  not  yet  through 
with  her  shenanigans.  Early  in  October  she 
whomped  up  a  hurricane  to  end  all  hurricanes, 
and  this  one  she  named  Hazel.  Again  coming 
up  out  of  the  Caribbean,  Hazel  struck  inland  as 
far  south  as  Myrtle  Beach,  S.C.  Through  North 
Carohna,  Virginia  and  Maryland  she  screamed 
in  full  fury.  In  the  mountains  of  Central  Pennsyl- 
vania she  lost  some  of  her  force,  onlj^  to  gather 
herself  for  one  last  blow  at  the  Toronto  area 
before  she  dispersed. 

Each  of  these  stormy  sisters  wept  millions 
of  gallons  of  rain,  tore  down  telephone  and 
electric  lines  in  witch-like  fury,  washed  out  roads, 
tore  off  roofs  and  smashed  houses  as  though 
they  were  made  of  paper,  and  sent  high  tides 
with  enormous  waves  smashing  against  beach 
resorts.  In  all  areas,  radio  amateurs  were  called 
upon  to  provide  emergency  communication. 
Many  of  them  have  written  Headquarters  to  tell 
us  about  it,  and  we  intend  to  chronicle  them  here. 
Many  more  have  never  let  us  know  what  they 
did.  This  account  is  written  on  the  basis  of  reports 
received. 

Carol 

The  Nassau  County,  L.  I.,  AREC  was  alerted 
by  the  Red  Cross  at  1210  on  August  31st,  and 
\V2KFV  was  put  into  operation  on  10  and  2 
meters.  Mobiles  were  dispatched  to  East  Rock- 
away,  Long  Beach,  Atlantic  Beach,  Point  Look- 


out, Island  Park,  Oceanside,  Freeport,  Baldwin, 
Jones  Beach,  Gilgo  Beach,  Bellmore,  Wantagh 
and  Seaford  on  the  south  shore,  and  Manor 
Haven,  Port  Washington,  Sea  Cliff  and  Bayville 
on  the  north  shore.  A  portable  2-meter  station 
was  set  up  at  Red  Cross  headquarters  in  Mineola. 
The  County  c.d.  station  was  activated  on  10 
and  2  meters  with  a  link  to  Red  Cross  head- 
quarters, from  which  contact  with  mobiles  was 
maintained.  W2KFV  operated  from  Red  Cross 
headquarters,  with  W2QBR  relieving,  and  at 
c.d.  headquarters  W2JKX  operated  on  10  and 
W2KEB  on  2,  assisted  by  K2EQH. 

Contents  of  messages  were  such  as  reports 
of  bridges  out,  trees  down  across  highways, 
electric  wires  down,  roads  washed  out  and 
fire  reports.  The  two-meter  station  at  Red  Cross 
was  secured  at  2135  after  a  message  of  commenda- 
tion had  been  read  from  the  disaster  chairman. 
Mobiles  in  operation  were  W2s  GCK  GPQ  KCW 
LLR  VQI  YIL  and  K2EWB.  Mobiles  standing 
by  were  W2s  DBI  DUS  KRP  OME,  K2s  AXF 
and  CCM.  W2LBJ  was  in  use  as  a  fixed  station. 
Other  stations  checked  in  and  standing  by  were 
W£s  ANN  AZA  KNA  NRL  QFH  TUK  UGF 
ZAI,  K2s  BGO  BJG  CNN  and  EAF.  K2DHC 
was  the  call  used  at  Nassau  County  c.d.  head- 
quarters. 

At  1000  EDST  on  the  morning  of  August  31st, 
WlVXL,  the  station  of  the  Cranston  Radio 
Association  located  at  the  Red  Cross  building, 
was  put  on  the  air  by  WIOGY  as  winds  reached 
hurricane  velocity  in  that  area.  Mobiles  WIBTV, 
WILZY  and  WlYKQ  called  in  shortly  after- 
ward, en  route  to  the  club.  When  power  failed, 
WIOGY  assumed  NCS  duties  from  his  mobile 
until  WlVXL  switched  over  to  emergency 
power.  By  1230  the  Cranston  Civil  Emergency 
Net  was  in  full  operation  with  WlPOP  operating 
WlVXL  and  sLx  mobile  units  out  patroling  or 
standing  by.  A  link  on  both  10  and  2  meters  was 
established  with  WlAFO/1  at  Cranston  Police 
Headquarters.  Other  mobiles  were  Wis  ZBZ 
and  YRY.  Others  standing  by  were  Wis  JYF 
OOX  RUS  WUH  ZPG  and  WNls  BQB  and 
YVW. 

In  the  late  afternoon,  WlWSY,  at  state  civil 
defense  headquarters  in  Scituate  and  other 
RACES  stations  were  activated  on  2  meters 
with  WIWKO  coordinating  information  for 
this  net  from  the  governor's  office.  WlVXL 
and  WlAFO/1  also  established  links  with 
WlWSY  and  WlWKO.  Operation  was  termi- 
nated about  midnight.  Accomplishments:  many 
messages  handled  for  the  mayor  and  Cranston 
police;  several  trips  to  accompany  Red  Cross 
vehicles;  handled  Red  Cross  and  other  emergency 
traffic;  picked  up  l)lood  plasma,  delivered  it  as

This  chart  shows  the  ap- 
proximate paths  taken  by  the 
three  hurricanes.  In  terms  of 
damage,  Carol  exceeded 
Edna,  but  Edna  was  the 
larger  in  size.  Hazel  was  the 
largest  of  all  in  both  cate- 
gories, and  we'll  tell  you  more 
about  her  in  the  next  install- 
ment. 


ONT, 


directed.  After  the  NCS  had 
secured,  Wis  YKQ,  LZY  and 
YIlY  traveled  in  convoy 
headed  by  the  state  c.d.  di- 
rector to  the  southern  part 
of  the  state  to  attempt  a 
survey  of  damage  and  leave 
a  portable  generator  at  the 
Narragansett  fire  station  to 
aid  in  setting  up  radio  com- 
munication. 

Amateurs  in  Hingham, 
Mass.,  under  direction  of  EC 
WlMD,  conducted  fire  pa- 
trol, since  most  of  the  city's 
telephones  and  fire-alarm  cir- 
cuits were  out.  The  following 
amateurs  participated  in  this 
activity:  Wis  AYG  BIY 
DMS  MD  NMK  SXN  and  W5HNW. 

In  the  New  Bedford  area,  WlAVY/1  was 
activated  on  75  meters  and  WlWKM  on  ten. 
The  following  operators  were  on  watch  at  these 
stations:  Wis  AEN*  AGG*  AVY*  AWH*  BMQ* 
CTZ*  HPH*  LAZ*  MHN  OH*  TZU*  UID 
WU*  WGN*  and  ZPE*.  Those  marked  with 
an  asterisk  also  operated  mobile  rigs  when  not 
on  duty  from  one  of  the  control  stations.  A  total 
of  538  messages  was  handled  to  and  from  the 
area.  New  Bedford  nets  also  tied  into  Fair- 
haven  on  ten  meters,  where  about  15  mobiles 
were  cooperating  with  local  pohce  and  mili- 
tary. 

The  Cape  Cod-Islands  Emergencj^  Net  on 
3912  did  a  very  fine  job  restricting  traffic  for 
Cape  and  Islands.  Other  nets  active  were  the 
Deep  Sea  Dragnet  on  3970,  Transcontinental 
'Phone  Net  on  3970  and  the  Early  Bird  Net  on 
3845. 

In  Worcester,  the  RACES  net  was  activated 
within  a  matter  of  minutes  by  Radio  Officer  and 


EC  WlSPF.  ^lost  of  the  damage  suffered  was 
from  rain,  although  power  was  off  over  most 
of  the  city.  Emergency  power  was  supplied  for 
c.d.  headquarters  by  the  ROTC  at  Worcester 
Tech.  WlSPF  reports  28  amateur  radio  operators 
on  duty,  plus  four  girls  with  restricted  operator 
permits  and  14  more  waiting  in  reserve.  The 
following  are  particularly  to  be  commended  for 
their  work:  WlNZD/m,  who  was  the  first  to 
report;  WlAET,  who  took  net  control;  WlSPG 
for  his  fine  work  in  relaying;  and  WIQCQ,  who^ 
took  over  at  WlYEW  net  control.  Other  ama- 
teurs participating  in  the  order  in  which  they 
made  their  appearance:  Wis  VDT  LIB/m  TJO 
ONA/m  SDU  NZD/m  UQL/m  VLN/m  AJV 
NNI/m  UQW/m  ZJW/m  CS  YPG  RIL  ZTL 
VPE/m  SPG/m  VGH  CLU/m  AAP/m  JWM/m 
and  \^^K. 

In  Norfolk  (Mass.,  that  is),  emergency  opera- 
tion was  complicated  by  a  prison  break  from  the 
Norfolk  Prison  Colony.  The  hurricane  hit  its  peak 
here  at  about  1500,  August  31st,  and  took  out  all

means  of  communication  other  than  radio.  A  gaso- 
line-driven generating  plant  was  set  up  at  the  fire 
station  and  the  amateurs  alerted.  Wis  WMN 
VQN  BFV  MJO  and  MGL  responded,  and  MJO 
was  dispatched  to  the  state  prison  colonj^  Wis 
MNW,  VQN  and  BFV  were  assigned  to  street 
patrol.  At  2245  a  report  from  the  prison  colony 
indicated  two  prisoners  had  escaped  and  were  on 
the  loose.  This  necessitated  the  setting  up  of  road 
blocks  and  an  even  greater  need  for  communica- 
tions. The  Norfolk  gang  were  on  duty  for  48  hours 
without  any  sleep.  EC  WICLF  reports  that  the 
prison  colony  superintendent  and  the  Norfolk 
police  chief  were  high  in  their  praise  of  the  work 
done  by  the  amateurs. 

Carol's  full  force  hit  Haverhill  about  noon  on 
August  31st,  by  which  time  telephone  service  was 
already  partially  disrupted.  At  1245  WISIX  was 
set  up  at  police  headquarters  and  made  contact 
with  WlCCF/1  at  c.d.  headquarters,  WIFW 
operating,  and  also  with  WlCCF/mobile  in 
downtown  Haverhill.  By  1330  mobiles  included 
Wis  SNZ  QYR  QZS  QQD  NAG  UHH  and 
WNIZUB,  all  cruising  the  city  to  report  fallen 
trees  and  wires  down.  Wis  WXE  RYV  WTK  and 
WNIAFM  came  on  later,  all  on  a  spot  frequency 
of  147  Mc.  With  almost  every  road  out  of  the  city 
blocked  by  fallen  trees  and  live  wires,  all  mobiles 
had  plenty  to  do.  Fire-alarm  and  police  signal 
systems  were  also  out.  The  stations  went  off  the 
air  0800  September  1st.  Later,  a  fire  patrol  was 
set  up  tying  various  fire  stations  together  and 
tying  West  Newbury,  Mass.,  in  with  the  Haver- 
hill system.  This  set-up  was  in  operation  until 
September  15th. 

The  hams  in  Braintree  became  active  starting 
at  1100  on  August  31st,  when  WlVTH  decided  to 
activate  WITYN,  the  civil  defense  station. 
Thirty-three  stations  reported  in,  of  which  22 
were  mobiles.  At  WlTYN,  WlVTH  was  joined 
by  WlVMU.  As  damage  reports  poured  in,  mo- 
biles were  dispatched  to  various  locations,  often 
accompanied  by  a  policeman,  to  try  to  keep 
everything  under  control.  Emergency  power  was 
necessary  at  1206,  and  WlTYN  was  off  the  air 
until  1225.  WlJOB  relieved  WlVTH  and  WlVMU 
at  1845,  but  VTH  was  back  on  the  air  from  his 
mobile  after  a  short  rest  and  some  chow.  Also 
operating  at  WlTYN  were  WlQPH  and  WlOSX 
(Braintree  c.d.  Comms.  Officer),  and  the  station 
was  on  the  air  until  2250.  Other  amateurs  partici- 
pating in  this  area:  Wis  I A  AUU  EKG  FQK  JQA

In  Framingham,  WIMEG  reports  six  mobile 
units  in  action:  Wis  WMT  LPM  RVA  MEG 
WPW  and  QQW.  In  Lynn,  EC  WlJLN  reports 
some  of  their  mobiles  went  to  Saugus  and  were  re- 
ceived heartily.  They  helped  patrol  the  town. 

The  situation  was  such  in  Arlington  by  1030 
that  the  town  manager  ordered  the  c.d.  hams,  the 
auxiUary  police  and  the  auxiliary  firemen  alerted. 
WlLXR  and  WITHO  were  the  first  alerted,  and 
moved  to  activate  the  control  station  at  the  civil- 
defense  director's  office.  WlWBX  acted  as  net 


control  operator  while  WlLXR  and  WlTHO  be- 
gan a  mobile  patrol  of  the  town.  WILLY  and 
WlCTW  entered  the  mobile  net  during  the  after- 
noon. Meanwhile,  the  six-meter  net  went  into 
operation  jointly  with  the  auxiliary  police,  look- 
ing for  live  wires  on  the  ground.  Mobiles  were 
Wis  BAQ  CTW  FWQ  LLY  LXR  NBI  THO 
VCZ  and  WYC.  WlWBX  and  WIWYC  alter- 
nated as  control-station  operators,  and  WlWBZ 
helped  maintain  equipment. 

At  the  peak  of  the  storm  in  Dedham,  EC  WISH 
requested  WlLYL  to  report  to  the  police  station 
to  assist  in  getting  the  town's  poHce  transmitter 
back  on  the  air,  since  power  was  off.  WlLYL  ran 
200  feet  of  power  cable  from  the  basement  to  the 
transmitter  on  the  top  floor.  The  c.d.  units  were 
then  able  to  operate  on  10  and  2  meters.  Return- 
ing to  his  home,  LYL  had  to  restore  his  own 
equipment  to  operating  condition,  to  go  into 
operation  on  75  meters  for  ten  consecutive  hours. 
A  big  day's  work  for  LYL. 

In  Winthrop,  WlTTH  and  WNIBOX  were 
fii-st  to  recognize  the  seriousness  of  the  situation 
and  report  to  the  control  center.  By  1030  the 
emergency  generator  was  functioning.  WlCMW 
also  activated  himself,  and  very  shortly  there 
were  10  stations  on  the  air.  Other  self-activated 
stations  were  Wis  VIS,  UOC,  and  HFJ.  Shortly 
after  1030  the  power  went  off,  and  the  emergency 
generator  was  put  on  the  line  to  supply  the  entire 
building,  including  police  radio  control  equip- 
ment, the  state  warning  and  emergency  civil- 
defense  equipment,  fights,  etc.  WlTTH  did  most 
of  the  operating  from  the  control  center.  The  six- 
meter  net  was  also  activated  and  contact  was 
maintained  with  Sector  4  headquarters  in  Newton 
throughout  the  emergency.  The  XYLs  helped  out 
as  operators  during  the  hurricane  and  deserve  a 
lot  of  credit.  Both  in  dayUght  and  at  night,  mo- 
bile units  were  used  extensively,  moving  from 
place  to  place  with  reports  of  conditions,  cooper- 
ating with  police  and  fire  units.  Operators  in 
this  work  were  Wis  UOC  TTH  HFJ  BB  and 
WNIBOX,  with  WIBDU  at  the  control  sta- 
tion. WlDJ  manned  the  Cottage  Hill  unit  and 
WlGGP  made  himself  available  at  the  hospital 
unit. 

In  Bedford,  WlRSY  was  on  the  air  within 
minutes  after  Carol  was  reported,  and  was  joined 
by  WlBFV,  who  was  assigned  to  the  Veterans 
Hospital,  and  by  WlACE/m  who  went  to  Has- 
comb  Air  Force  Base.  WlVCX  was  on  stand-by 
from  Maynard  until  his  own  area  was  alerted. 
When  WlRSY  lost  both  his  tower  and  power,  he 
got  on  from  his  mobile  rig.  C.d.  headquarters  was 
activated  by  Wl  YFP,  and  later  joined  by  mobiles 
Wis  VGC  EIQ  WAE  and  WME.  Wis  NAD  and 
NDI  drove  to  Acton  to  assist  WlTRD  who  was 
operating  alone  there.  Activity  continued  from 
0900  August  31st  to  0600  September  1st.  Wis 
TCG  UHV  YEP  and  ZSG  were  also  active. 

Edna 

After  the  unorthodox  behavior  of  Carol,  Edna 
was  tracked  very  carefully,  both  by  the  Weather 
Bureau  and  several  amateur  general-coverage 


44 


QST  for 


nets.  But  Edna,  although  larger  and  more  fero- 
cious than  her  predecessor,  followed  a  more  east- 
erly course.  Amateur  networks  were  alerted  and 
put  to  work  all  along  the  coast  as  Edna  made  her 
ponderous  way  northward,  and  indeed  consider- 
able damage  was  done  in  many  coastal  areas. 
This  rampant  female  finally  spent  the  last  of  her 
fury  in  the  Canadian  Maritime  Provinces. 

The  Transcontinental  Relaj'  Xet,  operating  on 
7042  kc,  and  a  special  Hurricane  Xet  set  up  on 
3910  principally  through  the  efforts  of  WlSS, 
followed  the  course  of  Edna  very  closely,  relying 
principally  on  reports  from  amateurs  in  her  waj'. 
TCRN  was  on  the  alert  as  soon  as  Edna  was 
born,  watching  her  closeh'  as  she  moved  north- 
eastward at  first  slowly,  then  with  gradually  in- 
creasing speed,  stajdng  a  hundred  miles  or  so  off 
the  East  Coast.  W4ATA  was  the  principal  source 
of  information  at  first,  and  he  gave  the  net  sev- 
eral advisories  until  September  9th,  when  Edna 
started  moving  toward  the  Carolina  coast;  then 
W4LM  of  Charleston  reported  in  to  help,  and 
later  W4PHJ  helped  supph'  weather  information. 
As  Edna  moved  northward,  TCRN  not  onh'  kept 
track  of  her  closely,  but  got  stations  all  over  the 
nation  into  the  network  to  handle  possible  hurri- 
cane traffic.  At  1215  EST  W2B0  reported  that 
the  hurricane  was  e.xpected  to  miss  most  of  Xew 
England,  brush  the  tip  of  Cape  Cod  and  pass  out 
to  sea  from  that  point.  .\s  the  storm  went  past  the 
New  England  coast,  WlLHA  and  WlDTB  gave 
frequent  reports,  the  latter  indicating  that  the 
worst  was  over  at  1900  EST.  The  following  were 
logged  by  W3CVE  as  having  participated:  ]Vls 
ARR  FEQ  DTB  OXX  PJF  YEJ  LHA,  W2s  BO

KL7ATO/W9  —  and  W3CVE,  of  course. 

WlSS  organized  a  Hurricane  Xet  on  3910  kc. 
during  Edna.  Constant  reports  of  movement  of 
the  storm,  wind  velocity  and  barometric  pressure 
readings  all  along  the  coast  from  Xew  Jersey  to 
Nova  Scotia  were  made  available  to  the  Asso- 
ciated Press,  the  United  Press  and 
the  International  News  Service, 
as  well  as  to  the  general  public 


and  stations  hstening  to  the  frequency.  Due 
to  experience  in  participating  in  emergency 
nets,  the  coordination  and  cooperation  of  all  the 
47  stations  that  comprised  the  net  made  for 
smooth  and  consistent  operation.  Actually,  WlSS 
counted  131  stations  reporting  in  at  one  time  or 
another,  including  the  following:  Wis  AFK  AHX

was  continuous  until  2142  that  night.  WlVVA, 
WIWCC  and  WlCRW  spelled  TVJ  as  NCS  at 
times.  Close  liaison  was  maintained  with  TCPN 
and  the  Maritime  Net,  and  much  traffic  was  expe- 
dited as  a  result.  Special  mention  should  be  made 
of  the  fine  work  done  by  WlBY,  W2J0A,  W3WV, 
WlCRW  (who  operated  from  his  mobile  rig 
much  of  the  time),  WlWCC  and  VEIXB. 


Emergency  power  units  were  mighty  valuable  during 
the  hurricanes,  and  many  AREC  units  remained  on  the 
air  simply  because  they  had  their  own,  like  the  Win- 
throp  organization.  That's  EC  WIBB  on  the  right,  and 
WIAGB  standing  in  the  rear. 

The  New  York  State  'Phone  and  Emergency 
Net  was  activated  at  1800  Sept.  10th  and  con- 
tinued through  to  1800  Sept.  11th  with  W2ILI 
as  net  control.  Approximately  175  net  members 
checked  in  on  the  net  frequency  of  3925  kc.  In 
addition,  the  New  York  State  Civil  Defense 
Amateur  Radio  Service  was  activated  and  stand- 
ing by  on  3993  kc.  with  30  stations  ready,  and 
v.h.f.  nets  on  6  and  2  meters  were  activated  with 
about  25  members.  Links  were  maintained  with 
Albany  and  National  Red  Cross  in  Washington, 
also  with  the  Hurricane  Net  and  the  New  England 
CD.  Nets. 

Damage  in  Rhode  Island  was  less  from  Edna 
than  from  Carol,  but  the  Cranston  Emergency 
Net  was  active  from  1910  Friday  evening  until 
2155  Saturday  at  the  request  of  the  Red  Cross. 
Net  control  station  WlVXL  was  activated  on 
29.52  Mc.  and  in  the  144-Mc.  band.  Mobiles 
alerted  included  Wis  BTV  LZY  YKQ  OGY 
ZBZ  OOX  and  YRY.  Wis  SGA  QLD  and  VAY 
called  in  and  stood  by  during  the  evening.  Mo- 
biles were  dismissed  but  on  Saturday  morning 
vvere  called  back  into  action.  A  fixed  station  was 
set  up  at  the  Red  Cross  evacuation  center  at 
Edgewood.  WlVXL  was  operated  by  Wis  POP 
BTV  ZPG  and  OOX,  and  on  two  meters  by 
WNIBQB  and  WlZGH.  WIAFO  was  operated 
at  police  headquarters.  WlEWT  and  WIQOF 
provided  a  link  with  Providence.  WlTQW  also 
furnished  a  fixed  link  in  downtown  Providence 
and  monitored  the  band  for  other  stations  and 
traffic  outside  the  Cranston  net  frequency'.  At 


the  height  of  the  storm  all  fixed  stations  operated 
on  emergency  power,  and  mobiles  were  on  patrol 
duty.  Official  traffic  was  handled  for  the  Cranston 
Police  and  the  Red  Cross.  Other  R.  I.  amateurs 
participating  in  the  operation  were  Wis  RUS 
RVO  SGA  BBN  QLD  MIJ  JYF  and  OAV. 

The  amateurs  in  Lynn  this  time  were  able 
to  do  some  collective  good  in  their  own  city 
by  setting  up  stations  in  the  various  firehouses. 
The  frequency  of  28,610  kc.  was  used.  Mobile 
Wis  WCB  HRA  QQL  MHK  OGK  JZV  were 
stationed  at  firehouses,  SHV  at  Red  Cross  head- 
quarters, VRK  at  the  Medical  Center  and  VHF 
at  Lynn  Hospital.  At  home  rigs  were  Wis  RLO 
LMJ  VUH  ZQL  UKE  YQF  TBL  DDI JKF  VHE 
CTD  and  KLC.  WlPBQ/m  was  in  contact  with 
Lynnfield  civil  defense,  MCC/m  with  Salem  civil 
defense  and  WlJLN/1  net  control,  operated  by 
JLN  and  MTG. 

In  Dedham,  WILYL  was  again  active.  At 
0820  on  September  18th  he  was  instrumental  in 
dispatching  mobile  equipment  from  BrookUne 
to  New  Bedford.  Later,  he  followed  the  eye  of 
Edna  and  relayed  these  reports  to  the  Dedham 
c.d.  office  on  2  meters.  Losing  power  at  1515,  he 
operated  mobile  on  2  meters  to  report  damage 
throughout  Dedham  as  to  road  blocks,  washouts 
and  other  damage. 

The  first  station  on  the  air  in  Winthrop  was 
WlMQB,  who  kept  an  all  night  vigil  on  Edna's 
progress  and  estimated  time  of  arrival.  The 
net  was  alerted  at  0700  Saturday  morning  and 
remained  in  operation  until  the  danger  from 
Edna  was  over.  The  following  were  also  active: 
Wis  DJ  CMW  OIR  OUC  HFJ/m  BB  BDU 
AGB/m  TTH  PBX  and  WNIBOX.  Civil  defense 
was  prepared  for  evacuation,  and  a  portable  unit 
manned  by  WITTH  was  ready  for  this  purpose. 
Officials  mobiling  about  town  checking  on  condi- 
tions were  kept  in  touch  with  the  report  center  by 
means  of  WNlBOX/m  on  two  meters.  The 
Winthrop  AREC  was  also  able  to  provide  an 
emergency  generator  for  power  for  essential  parts 
of  the  community  hospital. 

Hurricane  Edna  hit  Haverhill  on  September 
18th,  and  this  time  the  gang  was  ready.  WlCCF 
and  WlFW  were  on  stand-by  at  c.d.  headquarters 
starting  at  2200  on  the  17th,  other  units  coming 
on  the  air  about  0800  on  the  18th  and  staying  in 
operation  until  midnight  of  that  date.  A  unit 
was  again  set  up  at  West  Newbury,  tying  into 
Haverhill  c.d.  on  147  Mc.  Merrimac  was  tied 
in  on  28  Mc.  with  Wis  HP  REI  and  PIY  on  the 
air  in  that  town.  WIWTK  restored  an  emergency 
generator  which  failed  at  the  hospital.  Haverhill 
operation  during  Edna  was  a  continuation  of 
its  operation  from  Carol,  and  EC  WlSIX  sums 
up  participants  as  follows:  Wis  SNZ  RLT  KBQ 
CCF  SIX  FW  QYR  WTK  STA  IWR  MTS  QQD 
QZS  RYV  QQG  REI  HP  WXE  NAG  PIY, 
WNls  ZKB  AFM  and  ZUB. 

The  Framingham  Radio  Club  Net  was  alerted 
Friday  morning  by  WlMHC.  The  club's  gen- 
erator was  set  up  at  WlRXH,  who  took  over 
as  NCS  on  28,700  kc.  Framingham  being  head- 
quarters   for    Mass.    Civil    Defense    Region    3,

liaison  was  made  between  Framingham  and 
WlUQW  in  Worcester  on  29,560  kc,  contacts 
being  made  by  WlRXH  and  WlMEG/m.  The 
following  club  member  stations  were  activated: 
Wis  RXH  WMT/m  MHC/m  QQW/m  MEG/m 
SQY/m  WLJ  WPW/m  SRG  MQU/m  and  JUL. 
Operation  was  terminated  Sunday  afternoon. 

In  Hamilton  there  were  three  stations  active  — 
one  mobile,  one  emergency-powered  and  one 
control  station:  Wis  YLQ  TIN  and  LQQ  re- 
spectively. WlYLQ  and  WlTIN  were  active 
on  the  Hurricane  Net  on  3859. 

The  Braintree  gang  was  again  active  during 
Edna.  A  total  of  20  mobiles  turned  out  to  patrol 
the  streets,  reporting  conditions  almost  as  they 
occurred  to  the  police,  street,  electric  and  fire 
departments.  The  mobiles  assigned  to  assist  the 
electric  company's  crews  were  especially  active. 
WlVTH  and  WlZSZ  set  up  a  fixed  radio  station 
inside  the  electric  plant  to  act  as  net  control  for 
the  repair  crews.  Man}'  of  the.se  operators  served 
around  the  clock.  During  the  week  end  seven 
amateurs  with  a  combined  operating  time  of  41 
hours  served  as  net  control  operators:  Wis  SSA 
OSX  CTR  JOB  EKG  VTH  and  ZSZ.  The  follow- 
ing operated  as  mobiles:  Wis  .](.}\  KJD  KPX 
MPT  OSX  OFO  QPH  RRP  ROB  SSA  TQ(i

Wis  AUU  lA  ISU  KWD  LZB  LJT  MMH  QVX 
QPT  SAI  VYI  WXT  YKS  ZSU  ZYG. 

The  Bedford  gang  turned  out  for  Edna  as  they 
did  for  Carol,  and  again  assisted  the  Bedford 
civil  defense  in  maintaining  communication. 
EC  WlRSY  showed  up  at  c.d.  headquarters  at 
0600  on  Saturday  and  activated  the  control  sta- 
tion, setting  up  communication  with  Brookline. 
Concord,  Hingham  and  Lynnfield.  Later,  addi- 
tional help  showed  up  in  the  persons  of  ll'/x 
TCG  ZSG  XAD  SAP  YFP.  Operating  home 
stations  were  Wis  ACE  BFV  VGC  and  RSY. 

LTp  in  Manchester,  N.  H.,  the  Hillsborough 
County  Emergency  Net  went  into  operation  at 
1200  on  September  11th  under  net  control 
WlYHI  on  29  Mc.  The  net  covered  all  locations 
throughout  the  city  to  provide  communications 
with  c.d.  headquarters.  The  net  remained  in 
operation  until  1820.  Mobiles  in  action  were 
Wis  WUG  RGC  RYC  URL  YVX  TXK  and 
KYG.  Others  active  were  Wis  EIQ  KYX  MSJ

station  at  c.d.  headquarters  in  the  northern 
sector  of  the  city,  and  WIWUU  set  up  at  Moore 
General  Hospital  in  Grasmere. 

Edna  onty  sideswiped  these  areas,  but  the 
Canadian  Maritime  Provinces  felt  her  full  force. 
Saturday  afternoon,  Sept.  11th,  found  New 
Brunswick  net  control  VEIPF  sending  out  storm 
warnings  and  weather  reports.  By  1900  the 
3750  kc.  channel  was  so  congested  that  the  Xew 
Brunswick  and  Nova  Scotia  groups  divided,  the 


former  going  to  3740  and  the  latter  to  3770  kc. 
Yarmouth  was  the  first  to  feel  the  brunt  of  the 
storm,  and  shortly  after  2100  VElDW  and 
VEIACE  were  the  only  amateurs  being  heard 
from  that  area,  the  latter  mobile  and  the  former 
on  emergency  power.  Most  of  the  power  was 
off  at  Yarmouth,  and  VEIACE  patroled  the 
town  in  his  mobile  reporting  wires  down,  fallen 
trees,  etc.  VEIDW  was  in  contact  with  VEIFQ 
at  HaUfax,  which  station  was  also  on  emergency 
power.  VEIPT  was  patroling  the  Halifax  sub- 
urbs and  passing  damage  information  to  VEIFQ. 
.\ssisting  at  VEIFQ  were  VEIOM  and  VEILZ. 
Skip  washed  out  contact  toward  morning,  despite 
efforts  of  W2SAI  to  help  in  relajing,  but  opera- 
tion was  resumed  at  0700,  by  which  time  the 
storm  had  moved  to  the  Gulf  of  St.  Lawrence 
and  other  stations  in  that  area  were  beginning 
to  call  in.  Main  bulk  of  traffic  handled  on 
Sunday  consisted  of  telephone  and  power  line 


During  Edna,  EC  WIJLN  set  up  at  Fire  Alarm

TECHNICIAN  CLASS  FILING 

As  explained  in  detail  in  last  month's  editorial, 
the  Board  of  Directors  of  the  League  has  heartily 
endorsed  the  FCC  proposal  to  open  the  50-Mc. 
band  for  the  use  of  Technician  Class  amateur 
operators,  but  has  been  obliged  to  oppose  the 
similar  opening  of  144  Mc.  on  the  grounds  it 
would  defeat  the  original  purpose  in  increasing 
6-meter  occupancy.  The  text  of  the  League's 
fifing  with  the  Commission  follows: 

FEDERAL  COMMUNICATIONS  COMMISSION 
Washington  25,  D.  C. 


In  the  Matter  of 

Petitions  for  amendment  of  Part 

12,  Rules  Governing  Amateur 

Radio  Service,  concerning 

Technician  Class  operator 

privileges. 


DOCKET  NO.  11157 


COMMENTS  OF  THE 
AMERICAN  RADIO  RELAY  LEAGUE,  INC. 

Pursuant  to  Paragraph  6  of  the  Notice  of  Proposed  Rule 
Making  in  Docket  11157,  the  American  Radio  Relay 
League  files  these  comments  on  behalf  of  tlie  more  than 
45,000  U.  S. -licensed  amateur  radio  operators  who  are 
members  of  the  League. 

These  comments  were  formulated  after  extensive  de- 
liberation by  the  ARRL  Executive  Committee  and  subse- 
quent vote  by  the  elected  Board  of  Directors  of  the  League. 


The  League  concurs  in  the  proposal  to  open  the  50-Mc. 
band  to  amateur  licensees  of  the  Technician  Class,  but 
opposes  the  proposal  to  open  the  144-Mc.  band  for  those 
licensees.

QST  for 


Aa  to  60-Mc.  Technician  Use 

Some  time  prior  to  the  release  of  the  present  Notice  by 
the  Commission,  the  Executive  Committee  was  in  the 
process  of  examining  an  independent  proposal  received 
through  League  channels  that  the  50-Mc.  band  be  opened 
to  Technician  Class  licensees.  The  Committee  rendered  a 
report  unanimously  in  favor  of  such  a  proposal,  which  was 
thereupon  confirmed  by  the  Board  of  Directors.  Mean- 
while, the  Commission  released  its  own  proposal.  Thus  the 
League  heartily  endorses  that  portion  of  the  present  Docket 
which  proposes  to  open  the  50-Mc.  band  to  Technician 
Class  licensees. 

In  this  respect  the  League  concurs  with  the  Commis- 
sion's belief  that  "greater  occupancy  of,  and  experimenta- 
tion in,"  the  50-Mc.  band  is  desirable.  We  beUeve  that  the 
pattern  of  occupancy  of  an  amateur  band,  particularly  one 
above  30  Mc,  depends  to  a  considerable  extent  upon  be- 
ginner interest  in  such  band.  Beginner  interest  above 
30  Mc.  has  in  recent  years  been  concentrated  in  the  144-Mc. 
band,  with  little  or  none  shown  in  50  Mc.  The  League  be- 
lieves that  it  is  necessary  to  take  special  steps  to  promote 
beginner  interest  in  the  50-Mc.  band,  and  urges  the  adop- 
tion by  the  Commission  of  this  aspect  of  the  proposal. 

As  to  144-^tc.  Technician  Use 

With  the  issuance  by  the  Commission  of  the  present 
Notice,  proposing  that  Technicians  be  permitted  also  on 
144  Mc,  the  League  again  carefully  examined  the  matter, 
particularly  as  to  the  overall  effect  of  the  combined  pro- 
posals, and  both  the  Executive  Committee  and  the  Board 
of  Directors  voted  in  opposition  to  the  proposal.  Thus  the 
League  is  obliged  to  oppose  the  proposal  to  open  the  144-Mc. 
band  to  Technician  Class  Ucensees. 

The  League's  examination  of  the  proposal  fails  to  disclose 
any  compeUing  reason  for  its  adoption.  Occupancy  of  the 
144-Mc.  band  is  not  a  problem.  Since  the  war  this  band  has 
had  its  proportionate  share  of  amateur  use.  With  the  open- 
ing of  a  substantial  segment  of  it  for  use  by  Novice  Class 
licensees,  in  1951,  occupancy  has  increased  to  more  than 
an  adequate  level.  This  band  now  has  suitable  beginner 
interest,  which  we  have  stated  we  believe  is  so  necessary 
to  continued  occupancy.  Thus  we  see  no  immediate  need 
for  regulatory  action  to  promote  usage  of  the  band. 

Nor  does  the  League's  examination  of  the  proposal  enable 
it  to  agree  to  the  argument  that  its  adoption  would  increase 
participation  in  the  Radio  Amateur  Civil  Emergency  Serv- 
ice. Under  RACES  rules,  station  authorizations  may  not 
be  issued  to  the  holders  of  Technician  Class  Licensees.  Thus 
adoption  of  the  proposal  would  not  increase  the  number 
of  stations  available  for  civil  defense  communication  under 
RACES.  The  value  of  the  Technician  Class  licensee  to  civil 
defense  communications  lies,  of  course,  in  operator  avail- 
ability. In  this  respect  the  League  notes  it  is  already  pro- 
vided in  RACES  rules  that  Technician  Class  licensees  may 
obtain  authorizations  to  operate  in  that  ser\'ice,  using 
designated  segments  not  only  to  the  50-Mc.  band  but  any 
RACES  band  segment.  Thus  the  League  does  not  see  any 
specific  advantage  to  civil  defense  communications  by 
adopting  the  proposal  under  discussion. 

The  League  believes  that  adoption  of  the  proposal  would 
certainly  hinder,  if  not  actually  negate,  the  stated  aim  of 
obtaining  more  occupancy  also  in  the  50-Mc.  band.  Should 
both  bands  be  opened  to  Technician  Class  licensees,  in  the 
League's  opinion  such  Ucensees  would  congregate  on  144 
Mc.  almost  to  the  exclusion  of  50  Mc.  This  is  for  the  reason 
that  occupancy  tends  to  promote  occupancy,  and  such 
newcomers  would  be  drawn  to  the  band  of  greater  occu- 
pancy. Further,  obtaining  equipment  for  the  144-Mc.  band 
is  a  much  simpler  problem  than  for  50-Mc.,  both  in  respect 
to  commercially-available  units  and  surplus  equipment. 
The  only  result  would  be  greatly-increased  occupancy  of 
the  already-populated  144-Mc.  band  and  little  —  or,  more 
hkely,  no  —  increase  in  50-Mc.  activity.  This  would  ob- 
viously prevent  the  fulfillment  of  the  objective,  common 
to  the  Commission  and  the  League,  of  encouraging  greater 
occupancy  of  50  Mc.  It  is  primarily  for  this  reason  the 
League  is  obliged  to  oppose  the  144-Mc.  aspect  of  the 
proposal. 

Though  of  lesser  importance,  the  League  also  comments 
that  adoption  of  the  proposal  would  appear  to  make  the 
Technician  license  rather  too  attractive.  It  is  the  League's 
view,  and  one  which  we  believe  is  also  shared  by  the  Com- 
mission, that  incentives  should  be  provided  for  amateurs 
to  progress  to  higher  grades  of  license.  In  the  case  of  the 


Novice,  this  is  adequately  handled  by  the  one-year  license 
term.  In  the  case  of  the  Technician,  the  primary  incentive 
is  frequency  privileges.  In  areas  where  there  is  extensive 
v.h.f.  activity  there  are  hundreds  of  newcomers  who  will  be 
perfectly  satisfied  with  Technician  status  if  they  can  work 
on  all  frequencies  from  50  Mc.  up.  There  is  a  considerable 
number  of  amateurs  today  of  Conditional  Class,  or  higher, 
abeady  devoting  their  entire  time  to  v.h.f.,  and  perfectly 
content  to  do  so.  They  very  Ukely  would  never  have  both- 
ered to  obtain  their  present  class  of  license  had  all  the 
privileges  above  50  Mc.  been  available  to  them  with  a 
Technician  authorization. 

Summing  up,  the  League  believes  it  to  be  not  in  the  best 
interests  of  the  amateur  service  to  open  the  144-Mc.  band 
to  Technician  Class  licensees,  because  there  is  no  valid 
objective  to  be  accomplished,  because  such  action  would 
negate  the  desirable  objective  of  populating  the  50-Mc. 
band,  and  because  such  action  would  also  have  the  unde- 
sirable effect  of  removing,  to  a  considerable  extent,  incentive 
to  progress  to  a  higher  grade  of  license.

V.H.F.  BURSTS 

Thayer  School  of  Eng. 
Dartmouth  College 
Hanover,  N.  II. 
Editor,  QST: 

I  don't  know  whether  or  not  you  have  heard  from  Dr. 
deBett€ncourt,  but  Edward  P.  Tilton's  paper,  "  1000- 
Mile  Burst  Reception  on  144  Mc.  by  Radio  Amateurs," 
was  duly  presented  at  the  Xlth  General  Assembly  of  URSI 
at  the  Hague.  Sir  Edward  Appleton,  president  of  Inter- 
national Commission  III,  was  chairman  of  the  session  in 
which  the  presentation  was  made,  and  he  said  that  all 
of  the  bursts  looked  like  meteors  to  him.  Dr.  G.  MiUing- 
ton  of  Marconi's  Wireless  Company  presented  Mr.  G.  A. 
Isted's  work  on  the  correlation  of  v.h.f.  bursts  with  lightning 
strokes,  and  suggested  that  some  of  the  longer  bursts  on  the 
tape  might  be  this  phenomenon.  I  mentioned  that  you  were 
already  on  the  trail  of  this  matter  and  Appleton  was  most 
impressed  with  the  fact  that  amateurs  in  the  United  States 
would  be  aware  of  such  recent  work.  He  asked  that  the  Com- 
mission's highest  compliments  be  conveyed  to  W4HHK,  to 
W2UK,  and  to  WIHDQ  for  such  high  caliber  work  being 
carried  out  by  amateurs.

RTTY  ELECTION  RETURNS

New  York,  N.  Y. 
Editor,  QST: 

I  wish  to  express  my  thanks  for  the  fine  work  done  by- 
all  concerned  in  transmitting  by  amateur  radio  the  election 
returns  for  broadcast  by  the  Municipal  Broadcasting  Sys- 
tem. 

The  information  collected  and  forwarded  (by  John 
WilUams,  W2BFD,  and  his  fellow  operators)  was  received 
at  a  central  point  in  Manhattan  and  relayed  from  there  by 
amateur  radioteletype  directly  into  the  studio  from  which 
the  broadcast  originated. 

Due  to  their  good  work,  we  were  able  to  disseminate  these 
returns  about  two  hours  ahead  of  commercial  services. 

It  is  jobs  like  this,  well  done,  which  bring  to  public  atten- 
tion the  accomplishment  of  amateur  radio.

FAMILY  CIRCLE 

81.57  Harper  Ave. 
Chicago  19,  III. 
Editor,  QST: 

Bet  you  are  getting  quite  a  chuckle  out  of  the  feud  be- 
tween the  various  groups  whose  interests  seem  to  be  at 
variance  with  each  other.  I've  wondered,  reading  the 
letters,  if  it  has  ever  occurred  to  each  group  how  interde- 
pendent we  are  on  each  other,  really. 

To  those  who  love  to  build  gear  is  due  the  credit  for 
much  of  our  technical  advancement,  but  if  it  weren't 
for  those  who  love  to  operate,  what  good  would  advance- 
ment be?  If  no  one  wanted  to  operate,  except  to  test,  what 
use  could  be  found  for  new  circuits  and  equipment? 

The  ones  who  prefer  net  operation  to  free-lancing  make 
possible  the  traffic  handling  which  has  been  a  major  item 
in  the  justification  of  our  amateur  service.  However,  if  it 
weren't  for  the  free-lancers,  no  one  would  have  developed 
the  VFO. 

If  the  bands  hadn't  been  crowded,  no  one  would  have 
bothered  to  figure  out  the  crystal  filter,  and  if  no  one  had 
been  interested  in  "just  operating"  there  would  have  been 
no  one  to  use  it. 

If  everyone  built  their  gear  and  no  one  bought  it,  we 
would  not  have  the  advantage  of  manufacturers'  research, 
and  that  is  certainly  nothing  to  be  sneezed  at.  You  don't 


sneer  at  the  man  who  drives  a  Cadillac  just  because  he 
didn't  build  a  homemade  car  and  use  it  instead. 

The  boys  who  brag  about  their  design  abilities  seem  to 
forget  that  radio  has  already  been  invented,  and  they  are 
largely  making  improvements  in  design  rather  than  origina- 
tions, while  the  operators  who  razz  the  builders  forget  that 
their  gear  is  the  outcome  of  builders'  ideas. 

And  so  it  goes,  all  through  the  picture.  Each  would  be  a 
total  loss  without  the  other.  The  boys  who  knock  c.w.  should 
try  to  handle  traffic  through  heavy  QRN  and  QRM,  while 
those  who  knock  'phone  should  consider  how  it  expedites 
the  exchange  of  intelligence  when  conditions  are  right.  One 
could  go  on  and  on,  but  this  gives  you  the  idea.  We're  really 
just  one  family!

V.H.F.  FOR  CD.

Redstone  Arsenal 
HuntsviUe,  Ala. 
Editor,  QST: 

After  each  and  every  situation  where  emergency  traffic  is 
liandled  by  amateurs  I  read  the  comments  and  complaints 
about  stations  failing  to  clear  the  emergency  net  frequencies 
and  interfering  with  communications  in  general. 

Here  again  is  the  time  to  consider  the  further  exploitation 
of  v.h.f.  bands  for  practically  all  emergency  communica- 
tions. The  state  of  the  art  has  progressed  to  the  point  where 
the  reliability  and  range  of  v.h.f.  equipment  even  exceeds 
that  of  the  lower-frequency  units  of  equivalent  power  under 
most  conditions.  In  the  original  organization  of  many  nets, 
emphasis  was  placed  on  the  use  of  existing  equipment  among 
the  members.  This  fact  dictated  the  use  of  the  so-called 
"popular  bands."  As  time  progresses  it  becomes  more  im- 
portant to  turn  attention  to  more  effective  equipment  de- 
signed with  civil  defense,  etc.,  specifically  in  mind  for  more 
permanent  installations.  This  to  me  means  v.h.f.

DX  MANNERS

Editor,  QST: 

Oh,  what  lousy  manners  20-meter  DX  hounds  have.  Why 
can't  these  gentlemen  stop  frothing  at  the  mouth  and 
wait?  To  hear  some  of  them  you'd  think  that  the  only  way 
they  wiU  ever  be  satisfied  to  QSO  a  foreigner  is  to  break  up 
his  QSO  with  someone  else. 

As  a  victim  of  the  DX  hunter's  cunning,  I  speak!  How 
many  good  ones  have  been  snatched  from  my  trembling 
grasp  by  some  scheming  American?  Ouch,  boys,  pleez.  You 
can  wait!

HAWAIIAN  PARADISE 

P.  O.  Box  1748 
Lihue,  Kauai 
Editor,  QST: 

In  conversing  with  U.  S.  hams  plagued  with  TVI  and 
BCI,  they  frequently  have  expressed  their  desire  to  b; 
in  some  place  like  Hawaii. 

Far  from  being  a  dreamy  South  Pacific  isle,  Hawaii  has 
13  standard  broadcast  stations,  3  TV  stations,  and  3  f.m. 
stations,  not  to  mention  high-powered  communications 
facilities  by  the  major  communications  companies,  CAA, 
Army,  Navy,  and  electronic  navigational  facilities  serving 
the  entire  Pacific. 

So,  you  see,  it  is  not  all  hula  girls  and  pineapples  in  Hawaii.

Weil-Groomed  YLs 

IooK  to  your  dressing  table  .  .  .  your  mani- 
cure set  is  more  valuable  than  you  may 
-^  realize! 

In  the  General  Electric  Company's  service 
Ijublication,  "Techni-Talk,"  radio  serviceman 
L.  A.  Frankel  of  Astoria,  N.  Y.,  reveals  that 
milady's  manicure  set  can  serve  as  a  tool  kit  in 
the  field  of  radio  repair.  A  filed-down  orange 
stick  makes  a  good  nonconductive  screwdriver. 
Emery  boards  and  nail  files  can  clean  connections 
to  be  solderd.  Use  nail  polish  for  color-coding  or 
cement,  nail  polish  remover  as  a  plastics  solvent. 
Nail  clippers  can  cut  and  strip  small  wires,  and 
tweezers  can  pick  up  tiny  parts  drojjped  inside 
the  set  or  hold  small  parts  in  place  for  work 
within  cramped  confines. 

Wonder  what  useful  purpose  false  fingernails 
would  serve? 

"XYL"  or  "MYL" 

Wives  of  thirteen  members  of  tlie  East  Bay  Radio  Club 
(Oakland,  Calif.)  have  protested  the  use  of  the  term  "  XYL." 
They  suggest  that  unlicensed  wives  of  hams  be  referred  to 
as  "M  YLs  "  —  married  young  ladies.  This  renews  an  un- 
settled discussion  scanned  in  this  department  several  times 
previously.  ^         ,     _,    . 

The  complications  arc  increasing,  though.  "MYL  is 
the  term  most  frequently  offered  as  a  substitute  for  the 
popular  but  inappropriate  epithet  "XYL" — both  terms 
denoting  the  unlicensed  wife  of  a  male  amateur.  However, 
if  we  consider  the  merit  of  WlYNI's  suggestions  as  given 
in  the  .January,  54,  column,  an  "  MYL  "  would  be  a  married 
female  amateur  with  license.  (Bettys  comjilete  oflfering: 
"YL"  — single  woman  with  license;  "MYL"  —  married 
woman  with  license;  "SYL"  —  single  woman  without 
license;  "XYL"  —  married  woman  without  license.)  ^ 

What  will  be  tlie  fate  of  our  time-honored  "YL"  and

Hints  "** 

For  the  Experimente 


BETTER  AUDIO  WITH  THE  MONITONE 

AFTER  recent  completion  of  a  Alonitone,  it 
-LX.  was  discovered  that  the  audio  quality  was 
somewhat  distorted  at  normal  settings  of  the  re- 
ceiver gain  control.  The  received  signals  sounded 
chopped  or  clipped  at  the  audio  level  I  prefer  to 
use.  This  condition  was  quickly  remedied  by  the 
substitution  of  a  6SN7GT  for"  the  6SL7GT  rec- 
ommended for  the  circuit.  No  component  or  wir- 
ing changes  are  required  by  the  new  tube.

USING  A  CARPENTER'S  BRACE 
AS  A  WRENCH 

A  carpenter's  brace  makes  an  especially 
good  "wrench"  for  turning  the  square-head 
cap  screws  used  to  tighten  chassis  punches.  Fre- 
quently, when  the  corners  or  other  hard-to-get- 
at  places  of  a  chassis  are  being  tackled,  it  will  be 
found  that  a  brace  is  a  more  convenient  tool  to 
use  than  a  regular  flat  wrench.  Furthermore,  the 
ratchet  feature  of  the  brace  will  make  the  job  as 
easy  as  would  be  the  case  were  a  ratchet-type 
socket  wrench  employed.

INEXPENSIVE  FEEDER  SPREADERS 

PLASTIC  clothespins,  a  product  of  Vermont 
Plastics,  Inc.,  are  available  at  many  variety 
stores  at  a  cost  of  approximately  three  cents  each. 
Easily  disassembled,  each  provides  two  spreaders 
for  open-wire  lines.  One  hole  already  exists  in  the 
improvised  spreader,  and  the  other  can  be  drilled 
to  provide  two-inch  spacing.

THREE-BAND  OPERATION  WITH  A 
7-MC.  GROUND-PLANE  ANTENNA 

BECAUSE  of  the  growing  popularity  of  the 
quarter- wave  vertical,  especially  on  7  Mc,  it 
may  interest  some  of  the  gang  to  learn  that  this 
antenna  can  be  made  to  do  a  fair  job  at  3.5  and 
21  Mc.  also.  The  method  used  to  obtain  3- 
band  operation  here  at  W3NWA  is  shown  in 
Fig.  1. 

In  the  diagram,  L  is  a  loading  coil  used  when 
the  antenna  is  operated  at  3.5  Mc.  When  the 
s.p.d.t.  switch,  *S,  is  in  the  neutral  position,  it 
connects  L  in  series  with  the  radiator  and  the 
RG-8/U  transmission  line.  In  one  of  the  closed 
positions  the  switch  shorts  the  coil,  permitting 
normal  7-Mc.  operation  of  the  system.  The  an- 
tenna will  also  take  power  at  21  Mc.  when  the 
loading  coil  is  shorted  out.  In  the  third  position, 


the  switch  connects  the  vertical  to  the  grounded 
radial  support  to  provide  Ughtning  protection. 

In  the  original  installation,  the  Premax  whip 
was  adjusted  to  favor  operation  at  the  low  end  of 
the  7-Mc.  band.  The  loading  coil  used  to  resonate 
the  system  at  3550  kc.  consists  of  22  turns  No.  12 
enameled,  2J^-inch  diameter,  4  inches  long.  The

coil  was  cut  from  a  10-inch  length  of  commercial 
stock  which  had  been  temporarily  installed  intact 
and  then  tapped  experimentally  during  the  initial 
stages  of  testing.  A  grid-dip  meter  may  be 
used  to  help  resonate  the  coil,  provided  the  feed 
point  (the  coaxial  connector  shown  in  Fig.  1)  is 
connected  to  the  grounded  radial  support. 

A  liberal  appUcation  of  Duco  cement  along  the 
existing  support  bars  for  the  air-wound  coil  will 
provide  added  strength  to  the  assembly.  One  coil 
so  treated  has  been  exposed  to  the  weather  for  an 
entire  winter  with  no  apparent  ill  effects. 

In  actual  operation  at  3.5  Mc,  good  reports 
have  been  received  from  all  over  the  eastern  part 
of  the  U.  S.  A.,  using  100  watts  on  c.w.  Reports 
are  consistently  better  than  formerly  received 
while  using  a  random-length  horizontal  wire, 
probably  due  in  part  to  the  low-angle  radiation 
from  the  vertical.  The  s.w.r.,  while  not  as  low  as 
on  7  Mc.  (using  the  same  RG-8/U  feeder),  is  not 
high  enough  to  cause  trouble,  provided  operation 
is  Umited  to  a  100-kc.  band  centered  on  the  fre- 
quency for  which  the  loading  coil  has  been 
resonated.

QST  for 


8th  V.H.F.  Sweepstakes,  Jan.  8th-9th 

ARRL  Certificates  to  Leaders;  Gavel  to  Top  Club 


THE  Eighth  Annual  V.H.F.  Sweepstakes,  open 
to  all  amateurs  who  can  work  50  Mc.  or 
higher,  will  offer  the  v.h.f .  enthusiast  unparal- 
leled opportunities  for  new  DX  records,  addi- 
tional states,  and  meeting  new  friends.  The  con- 
test period  starts  at  2:00  p.m.  your  local  time, 
Saturday,  January  8th,  and  continues  to  mid- 
night, Sunday,  January  9th. 

Just  call  "CQ  Sweepstakes"  on  'phone  or 
"CQ  SS"  on  c.w.  to  get  in  touch  with  other 
contestants,  then  exchange  SS  data  as  shown 
elsewhere  in  this  announcement.  This  informa- 
tion is  similar  to  a  message  preamble,  with  the 
ARRL  section  (see  page  six  of  this  QST)  sub- 
stituted for  the  city  and  state,  and  the  RS  or 
RST  report  for  the  "check." 

Make  contact  with  as  many  stations  as  pos- 
sible. (You  can  rework  a  station  for  credit  on 
other  v.h.f.  bands,  so  ability  to  work  several 
bands  pays  off  in  score  points.)  When  an  ex- 
change of  SS  "messages"  has  been  completed  in 
both  directions,  two  points  may  be  claimed. 

To  figure  your  score,  multiply  total  contact 
points  by  the  number  of  different  ARRL  sections 
worked.  You  may  use  'phone,  m.c.w.,  or  c.w., 
with  results  all  contributing  toward  one  score. 

Certificate  awards  will  go  to  V.H.F.  Sweep- 
stakes top-scorers  in  each  of  the  73  ARRL  sec- 
tions from  which  entries  are  received.  In  addition. 


a  certificate  will  be  given  to  the  top  Novice  or 
Technician  in  each  section  where  at  least  three 
such  licensees  submit  valid  contest  logs. 

Clubs,  especially,  are  urged  to  get  their  mem- 
bers on  the  air  from  their  individual  stations  to 
compete  for  the  certificates  which  go  to  leading 
club  operators.  The  club  whose  members  ac- 
cumulate the  top  aggregate  score  will  also 
receive  a  cocobolo  gavel  with  a  sterling-silver 
band  engraved  with  the  name  of  the  winner. 

Contest  reporting  forms  are  now  available 
from  the  ARRL  Communications  Department 
and  will  be  sent  free  upon  request.  If  you  don't 
use  these  forms,  please  follow  the  log  arrange- 
ment shown.  ARRL  welcomes  all  contest  reports 
to  assist  in  cross-checking  and  to  make  complete 
results  in  QST  possible.  Novices  and  Techni- 
cians: be  sure  to  report  your  totals,  large  or  small, 
so  that  the  license-class  leader  in  your  section 
will  qualify  for  a  certificate. 

The  1954  V.H.F.  Sweepstakes  smashed  all 
v.h.f.  activity  records  before  or  since,  with  an 
unprecedented  610  stations  reporting.  The  SS 
coming  up  may  well  be  bigger  yet.  Why  not  give 
your  v.h.f.  set-up  a  check?  In  this  one  January 
week  end,  you'll  be  able  to  tell  more  about  how 
your  equipment  and  antennas  are  functioning 
than  in  months  of  casual  operating.  Plan  now  to 
take  part!  (Rules  on  following  page.)

Rules 

1)  Eligibility:  Amateur  operators  in  any  ARRL  section 
(see  page  6)  operating  at  home,  or  mobile  or  portable  under 
one  call  on  or  above  50  Mc.  are  invited  to  take  part. 

2)  Object:  Participants  will  attempt  to  contact  as  many 
other  stations  in  as  many  ARRL  sections  as  possible. 

3)  Contest  Periods:  The  contest  starts  at  2:00  p.m.  your 
local  time,  Saturday,  Jan.  8,  1955,  and  ends  at  midnight, 
Sunday,  Jan.  9,  1955. 

4)  Exchanges:  Contest  exchanges,  including  all  data 
shown  in  the  sample,  must  be  transmitted  and  receipted 
for  as  a  basis  for  each  scored  point. 

5)  Scoring:  (a)  Contacts  count  one  point  when  the 
required  exchange  information  has  been  received  and 
acknowledged,  a  second  point  when  exchange  has  been  com- 
pleted in  both  directions. 

(b)  Final  score  is  obtained  by  multiplying  total  contact 
points  by  the  number  of  different  ARRL  sections  worked 
(the  number  in  each  of  which  at  least  one  SS  point  has 
been  credited). 

6)  Conditions  for  Valid  Contact  Credit:  (a)  Repeat  contacts 
on  other  bands  confirmed  by  completed  exchanges  of  up  to 
two  points  per  band  may  be  counted  for  each  different  station 
worked.  {Example:  WIHDQ  works  W8BFQ  on  50  and  144 
Mc.  for  complete  exchanges  of  2  points  on  each  band;  2  -|-  2 
gives  4  points  but  only  one  section  multiplier.) 

(b)  Cross-band  work  shall  not  count. 

(c)  Portable  or  mobile  station  operation  under  one  call, 
from  one  location  only,  is  permitted. 


7)  Awards:  Entries  will  be  classified  as  single-or  multi- 
operator,  a  single-operator  station  being  defined  as  one 
manned  by  an  amateur  who  neither  receives  nor  gives  as- 
sistance to  any  person  during  the  contest  period.  Certificates 
will  be  awarded  in  each  ARRL  section  to  tlie  top-scoring 
amateur  in  the  single-operator  classification.  In  addition,  a 
certificate  will  be  awarded  to  the  top  Novice  or  Technician 
in  eacli  ARRL  section  where  at  least  three  such  licensees 
submit  valid  contest  logs.  Multioperator  work  will  be 
grouped  separately  in  the  official  report  of  results  in  QST. 

When  three  or  more  individual  club  members  compete 
and  submit  logs  naming  the  club  with  which  they  are  identi- 
fied, an  ARRL  certificate  will  be  issued  to  the  leading  club 
member.  When  less  than  three  individual  logs  are  received 
there  will  be  no  club  award  or  club  mention. 

A  gravel  with  an  engraved  sterling-silver  band  will  be 
offered  the  club  whose  secretary  submits  the  greatest  aggre- 
gate score,  provided  such  scores  are  confirmed  by  receipt  at 
ARRL  of  the  individual  contest  logs  from  such  members 
(resident  club  members  only).  Claims  from  federations, 
radio  club  councils,  or  other  combinations  of  radio  clubs, 
will  not  be  accepted.  Special  memberships  granted  for  con- 
test purposes  will  not  be  recognized. 

8)  Conditions  of  Entry:  Each  entrant  agrees  to  be  bound 
by  the  provisions  of  this  announcement,  the  regulations  of 
his  licensing  authority,  and  the  decisions  of  the  ARRL 
Award  Committee. 

9)  Reporting:  Reports  must  be  postmarked  no  later  than 
January  24,  1955,  to  be  considered  for  awards.

Those  who  have  owned  preceding  editions  of  the  "  Receiv- 
ing Tube  Manual"  will  hardly  need  more  than  the  word 
that  a  new  edition  is  out,  since  it  is  an  old  stand-by.  In  addi- 
tion to  containing  more  detailed  data  on  receiving  tubes 
and  kinescopes  than  can  be  obtained  from  the  conventional 
tube  tables,  the  new  edition  continues  (with  additions)  the 
sections  on  tube  operation,  installation  and  rating  informa- 
tion, amphfier  and  oscillator  design,  and  the  resistance- 
coupled  amplifier  tables.  Some  new  hi-fi  circuits  have  also 
been  added  to  the  circuit  section.  Altogether  a  most  useful 
member  of  tiie  amateur's  library.

CONDUCTED  BY  EDWARD  P.  TILTON,   WIHDQ 


We're  indebted  to  W6BCX  for  bringing  the 
idea  back  into  focus.  During  a  visit  with 
him  and  W6VR,  Wood}'  dug  into  his  QST 
file  and  came  up  with  the  July,  1928,  issue,  ^id 
I  remember  the  "Warner  Splatter  System"  of- 
fered to  a  waiting  world  by  the  late  K.  B.  Warner 
on  the  editorial  page  of  that  issue  of  more  than 
25  years  ago?  The  idea  was  to  spray  large 
amounts  of  r.f.  at  the  ionosphere;  if  you  throw 
enough  stuff  up  there  some  of  it  is  bound  to  come 
back  down  again  —  "just  as  a  firehose,  with  its 
nozzle  directed  at  the  ceiUng  would  provide  a 
sure-fire  way  of  wetting  every  square  inch  of 
the  floor  in  jig  time." 

KBW  was  always  coming  up  with  something 
Hke  that;  concepts  that  had  everyone  laughing 
at  the  time,  but  somehow  had  a  way  of  proving 
out  years  later.  He  was  talking  of  10-meter  DX 
then,  but  he'd  be  vastly  amused  to  find  what  is 
essentially  his  splatter  system  in  use  today, 
providing  consistent  communication  in  the  v.h.f. 
range  over  distances  of  1000  miles  or  more.  And 
making  v.h.f.  work  possible  from  locations  where 
no  ham  in  his  right  mind  would  have  tried  50  ^NIc. 
or  higher  bands  even  a  few  years  ago. 

It  is  just  such  "scattering  from  irregularities 
in  the  ionosphere,  when  other  forms  of  iono- 
spheric transmission  are  absent"  ^  that  is  now 
assumed  to  be  responsible  for  the  success  of 
the  well-known  Cedar  Rapids  to  Washington 
experiment  on  49.8  Mc.  and  higher  frequencies. 
And  a  very  similar  kind  of  scattering,  ionospheric 
and  tropospheric,  is  being  used  by  some  of  our 
best  2-meter  stations  in  working  consistently 
over  distances  up  to  500  miles  or  so. 

The  beauty  of  all  this  is  that,  since  an  elevated 
scattering  medium  is  involved,  the  location  of 
the  v.h.f.  station  is  relatively  unimportant.  If  the 
normal  radiation  pattern  of  your  array  clears 
obstructions  in  the  immediate  vicinity  of  your 
antenna,  you  may  do  just  as  well  in  this  kind  of 
v.h.f.  DX  as  the  fellow  on  the  top  of  a  hill.  A 
high  hill  is  still  nice  to  have,  but  it  is  by  no  means 
necessary  for  successful  v.h.f.  work. 

But  suppose  j^ou're  a  valley  dweller;  you  look 
out  from  your  shack  window  to  snow-capped 
mountain  peaks  in  every  direction.  \Miat  chance 
is  there  for  a  v.h.f.  man  in  such  a  spot?  Well, 
don't  give  up  until  j'ou've  given  it  a  good  try; 
you  may  find  that  you  have  a  really  good  loca- 
tion. No,  don't  send  for  the  men  in  the  white 
coats;  it  can  be  that  way.  Your  snug  valley  may 
turn  out  to  be  better  than  a  spot  out  on  the  open 
plains ! 

We've  mentioned  "knife-edge  refraction"  in 

iN.B.S.  Technical  Report  No.  1682,  Augiist,  1952. 

January  1955 


these  pages  before,  but  our  recent  s-ning  through 
much  of  our  really  high  mountain  country  showed 
that  few  v.h.f.  men  (present  or  potential)  in  these 
areas  have  given  much  thought  to  the  appUcation 
of  the  theory  to  their  particular  set  of  circum- 
stances. Yet  it  has  been  demonstrated  that  a 
sharp  ridge  at  just  the  right  point  between  two 
low-lying  v.h.f.  stations  can  provide  enough  re- 
fraction to  bring  the  signal  level  up  more  than 
70  db.  above  the  value  that  would  be  obtained 
over  the  same  distance  in  open  terrain! 

Few  hams  are  likely  to  be  fortunate  enough 
to  achieve  any  such  "obstacle  gain"  but  again 
and  again  in  our  mobile  work  in  the  western 
mountains  we  saw  knife-edge  refraction  at  work. 
In  several  instances  we  had  strong  signals  over 
mountainous  paths  of  greater  length  than  we've 
ever  worked  over  rolling  New  England  or  the 
flat  Middle  West.  And  of  course  the  2-meter  work 
between  Arizona  stations  and  others  at  distances 
of  350  miles  or  more,  recently  reported  in  these 
pages,  is  further  proof  that  high  mountains  are, 
at  least,  no  certain  barrier. 

Add  to  these  factors  the  still  newer  possibility 
of  v.h.f.  DX  by  reflection  from  meteor  trails,  now 
being  exploited  by  W4HHK,  W2UK  and  others, 
and  the  tropospheric  and  auroral  phenomena 
we've  known  about  for  years,  and  you  have 
rather  convincing  evidence  that  v.h.f.  can  be 
fun  just  about  anywhere.  Are  you  getting  in  on 
it? 

Don't  jump  to  the  conclusion,  from  what  we've 
been  sa^-ing,  that  all  j^ou  need  is  a  522  and  a 
folded  dipole  to  work  400  miles  over  the  moun- 
tains on  144  Mc.  It's  not  that  simple,  by  any 
means,  or  we'd  have  been  doing  it  long  ago.  The 
signals  you  get  over  long  indirect  paths  are  Hkely 
to  be  very  weak  at  best;  you'U  need  plenty  of 
power,  a  good  big  antenna,  and  the  best  available 
receiver  to  turn  the  trick.  Highly  selective  re- 
ceivers and  c.w.  techniques  are  a  must,  at  least 
at  first.  If  you've  tried  a  tough  path  and  failed, 
with  anything  less  than  a  combination  of  all 
these  assets,  you  can't  say  that  it  can't  be  done. 
Working  long  hauls  over  high  mountains  is^ 
job  to  separate  the  men  from  the  boys.  Give  it 
all  you've  got,  and  the  chances  are  j^ou'll  be 
pleased  with  the  results! 

OES  Notes 

W2RHQ,  Syracuse,  N.  Y.  —  Now  on  432  Mc.  with  2C39 
grounded-grid  amphfier,  driven  by  an  832A  tripler.  Would 
like  to  hear  from  anyone  with  dope  on  gear  for  1215  Mc. 
Recently  got  32-element  144-Mc.  array  working  properly 
by  bringing  two  16-element  sections  closer  together.  With 
the  orighial  arrangement  (sections  a  half  wave  apart  between 
element  ends)  there  was  a  split  forward  lobe.  Now  hearing 
W2UK,  W3BGT  and  other  distant  stations  off  the  backs  of 

55 


their  beams  fairly  regularly;  wish  stations  in  New  Jersey 
and  Pennsylvania  would  aim  toward  central  New  York 
State  more  often. 

W2UTH,  Victor,  N.  Y.  —  Back  in  business  in  new  loca- 
tion after  extensive  damage  to  house  and  antennas  by 
Hurricane  Hazel.  Activity  on  220  Me.  developing  in  Roches- 
ter area  with  W28  POM  RTB  MHU  UXP  and  K2CEH  on. 

W3UQJ,  York,  Pa.  —  Would  like  to  hear  as  to  results 
from  anyone  who  has  tried  220-Mc.  mobile.  Suggest  more 
use  of  c.w.  on  220,  as  contacts  have  been  made.  As  result  of 
many  skeds  with  W3LZD,  W3SJB,  W3UJG  and  W4UMF, 
it  has  been  found  that  anytime  a  readable  signal  is  heard  on 
144,  220  is  just  about  equally  good. 

W4FLW,  Dresden,  Tenn.  —  Gradually  developing  more 
activity  on  50  and  144  Mc.  Working  W4CYR,  Nashville, 
and  W4HF0,  Martin,  on  6  and  W4BQG,  McKenzie,  on  2. 

W4HHK,  Collierville,  Tenn.  —  Daily  skeds  continue  with 
W2UK  and  WIHDQ.  Burst  count  on  W2UK  runs  as  high 
as  79  for  his  10-minute  tape  transmission  at  0640  CST. 
WIHDQ  heard  fairly  regularly,  but  with  lower  burst  count, 
on  5-minute  transmission  at  0635  CST.  Similar  meteor- 
scatter  skeds  with  W5VWU,  Albuquerque,  N.  Mex.,  960 
miles,  have  produced  only  unidentifiable  pings,  though 
W5VWU  copied  complete  call  sequence  on  one  occasion. 
Tests  also  being  made  with  W7VMP,  Phoenix,  Ariz.,  1300 
miles,  but  no  identifiable  sigs  either  way  as  yet. 

Revamped  crystal-controUed  converter  recently,  putting 
in  overtone  crystal  on  45.667  Mc.  Enough  frequency  varia- 
tion is  possible  in  tuning  the  oscillator  plate  circuit  so  that 
it  can  be  set  exactly  on  frequency,  multiplying  to  137  Mc. 
Now  the  communications  receiver  dial  reads  exactly  7000 
kc.  for  144  Mc,  a  real  aid  in  keeping  weak-signal  skeds. 

W5GIX,  Baton  Rouge,  La.  —  New  Orleans  and  Jackson, 
Miss.,  always  reliable  on  144  Mc.  W4UUF,  Pensacola,  Fla., 
W4TLV,  DemopoUs,  and  W40ZK,  Gadsden,  Ala.,  also 
heard  frequently. 

W60RS.  Alhambra,  Calif.  —  Working  on  220-Mc.  crystal- 
controlled  converter.  Rig  for  220  Mc.  (Feb.,  '54,  QST)  work- 
ing nicely. 

W6ZD0,  Canoga  Park,  Calif.  —  Daily  operation  on  220.9 
and  221.1  Mc;  conditions  much  hke  112  and  56  Mc.  of 
many  years  ago,  even  to  superregen  receiver  QRM!  Con- 
verted 1350-Mc.  radiosonde  to  1215-Mc.  band. 

W7JHX,  Port  Orchard,  Wash.  —  Made  first  TV  transmis- 
sion Oct.  18th.  Put  rig  on  following  evening  and  left  it  run- 
ning while  away  from  home.  Main  power  transformer 
shorted,  causing  much  smoke  and  excitement.  Everything 
repaired  within  a  few  days,  and  can  now  transmit  video  on 
441.36  Mc.  any  evening  and  Sundays  by  appointment.  Can 
usually  be  reached  on  2  meters,  or  through  Puget  Sound 
Net. 

W9KLR,  Rensselaer,  Ind.  —  Here's  a  fellow  who  must 
hold  some  kind  of  record:  W9JNZ,  on  the  air  three  times 
since  he  was  Ucensed,  made  20  contacts  in  15  states  and  6 
call  areas  on  144  Mc! 

VE7FJ,  New  Westminster,  B.  C.  —  Much  talk,  by  W7s, 
of^going  horizontal  on  144  Mc.  VE7s,  always  in  favor  of 
horizontal,  will  welcome  change. 

V06U  and  W7SNR/V06,  Goose  Bay,  Labrador  — 'LocaX 
activity  on  50,  144  and  220  Mc.  These  fellows  should  have 
a  fine  opportunity  to  make  v.h.f.  historj',  if  they  watch  con- 
ditions closely  for  chanres  to  work  down  tlin  .Atlantic  Sea- 
board and  elsewhere.

C.  W.  Reception  with  the  Communicator 

Use  of  c.w.  on  144  Mc.  is  increasing  all  the  time,  and 
probably  would  have  progressed  further  if   there  were  some 
{Continued  on  page  134) 


With  this  24-element  array, 
W7LHL/7,  Bolan  Peak,  in  southern 
Oregon,  worked  the  Northwest's  best 
2-meter  DX  in  the  September  V.H.F. 
Party. 


QST  for 


September  V.H.F.  Party  Results 

Increased  Western  Activity  Nets  Record  Number  of  Logs 


WE  MAY  never  be  able  to  set  up  any  wholly 
fair  system  for  scoring  v.h.f.  contests, 
or  any  other  operating  activity,  on  a  na- 
tional scale,  but  the  disparity  between  various 
sections  of  the  country  is  dropping  with  every 
v.h.f.  party.  Of  course,  a  "national  high"  is 
only  a  mythical  honor,  anyway,  as  there  is  com- 
petition only  within  your  own  ARRL  section, 
but  it  is  interesting  to  look  through  the  tabula- 
tion at  the  end  of  this  report  and  see  where  the 
really  high  scores  were  made. 

Of  the  geographically  small  and  densely  pop- 
ulated ARRL  sections  along  the  Eastern  Sea- 
board, only  Northern  and  Southern  New  Jersey, 
Western  Massachusetts,  New  Hampshire  and 
Connecticut  reported  September  V.H.F.  Party 
totals  higher  than  the  2095  points  piled  up  in 
the  East  Bay  Section  by  K6GWE,  Berkeley, 
Calif.  Five  eastern  sections,  supposedly  cinches 
for  high  spots  in  a  national  ranking,  were  topped 
by  Illinois,  Ohio,  Michigan,  Santa  Clara  Valley, 
East  Bay  and  Los  Angeles. 

Ignoring  the  section  multiplier,  an  unfair 
factor  in  national  comparisons,  we  find  that  the 
number  of  contacts  made  is  becoming  more  uni- 
form, the  country  over,  with  every  contest.  In 
only  two  ARRL  sections.  Northern  New  Jersey 
and  Los  Angeles,  were  more  than  200  contacts 
reported.  In  the  bracket  between  150  and  200, 
we  find  Illinois,  Ohio,  Western  Massachusetts 
and  New  Hampshire.  Of  the  sections  reporting 
100  to  150  contacts,  Indiana,  Michigan,  Santa 
Clara  Valley  and  East  Bay  are  outside  the  "fa- 
vored" Atlantic  Seaboard  states.  The  country's 
highest  one-band  score  was  made,  not  by  an 
East  Coast  station,  but  by  W8WXV,  Shiloh, 
Ohio,  who  worked  196  stations  in  17  sections, 
3332  points,  on  144  Mc.  alone. 

The  ability  to  work  several  bands  is  the  most 
important  factor  in  high  scoring,  in  any  section. 
The  rules  were  set  up  with  that  in  mind:  to  pro- 
mote versatility  and  encourage  the  use  of  our 
higher  bands.  Working  all  bands  from  50  to 
1215  Mc.  enabled  K2CMB,  Paterson,  N.  J., 
to  make  280  contacts  for  8456  points,  the  coun- 
try's high  for  a  single-operator  set-up.  The  230 
contacts  of  W6WSQ,  Pasadena,  Calif.,  made  on 
50,  144  and  420  Mc,  is  second  in  number  of 
QSOs.  Lee  Waite,  W2FBZ,  a  frequent  Northern 
New  Jersej^  wnnner,  worked  4  bands  for  206 
contacts  and  7488  points,  running  K2CMB  a 
close  second  for  national  single-operator  high. 

Mountain  expeditions,  as  always  in  spring 
and  fall  parties,  contributed  greatly  to  the  suc- 
cess of  the  contest.  For  once,  the  WlMHL/1 
team  came  off  second  best.  A  combination  new 
to  v.h.f.  contests  but  with  long  Field  Day  ex- 
perience, W2GSA/2,  Garden  State  Amateur 
Radio    Association,    nosed    out    the    Waltham 


group,  with  327  contacts  on  50,  144  and  220 
Mc,  for  9715  points.  Some  nice  2-meter  DX  was 
worked  in  the  Northwest  b}^  mountain  portables. 
W7PVZ/7  in  a  fire  lookout  on  Capitol  Peak, 
near  Olympia,  Wash.,  worked  W7LHL/7  on 
Bolan  Peak  in  Southern  Oregon,  about  350 
miles.  An  indication  of  the  growth  of  2-meter 
interest  in  that  region:  W7PVZ/7  worked  83 
different  stations  on  144  Mc. 

The  1215-Mc.  band  loomed  as  a  v.h.f.  con- 
test factor  of  some  proportions.  As  the  result

of  cooperative  effort  by  K2CMI,  K2DFS  and 
W3UQB,  five  nearly  identical  1215-Mc.  stations 
were  built.  These  used  2C39  cavity  oscillators, 
delivering  about  12  watts  output.  Tuned-cavity' 
crj-stal  mixers  with  144-Mc  output  worked  into 
Gonset  Communicators  as  tunable  i.f.'s.  Dupli- 
cate corner-reflector  arrays  were  used  for  trans- 
mission and  reception.  The  rigs  were  used  by 
WlJRV/1  at  Mead  Pond,  just  over  the  line  in 
Connecticut,  W3UQB/2  at  Balanced  Rock, 
Nyack,  N.  Y.,  K2DFS,  at  his  home  in  Bergen- 
field,  N.  J.,  and  K2CMI/2  and  W2FSN/2  in 
Manhattan  high  spots,  to  give  K2CMB  five  con- 
tacts in  four  ARRL  sections  on  1215  Mc. 

Around  San  Francisco  there  was  enough  doing

on  144  Mc.  so  that  W6TDP  made  56  contacts 
with  5  watts  input  to  a  5763  doubler  (rig  built 
from  W2IHW's  description  in  February,  1954, 
QST),  and  a  cut-dowTi  TV  Yagi  hung  in  his 
basement ! 

Two  0-0-0  scores  don't  appear  in  the  tabula- 
tion, but  they  represent  effort  and  good  inten- 
tions. One  goes  to  W7RCC,  Panguitch,  Utah, 
who  was  in  there  trying,  but  heard  no  signals. 
The  other  was  earned  by  WlHDQ/0.  Your 
conductor  got  up  before  0600  Sunday  morning 
and  drove  out  from  the  Dakota  Division  Con- 
vention Headquarters  in  Rapid  City,  S.  D.,  to 
a  fine  clear  spot  in  the  Black  Hills.  Having  been 
in  every  v.h.f.  contest  since  the  first  one  in  1939, 
he  was  going  to  give  this  one  the  "college  try," 
l)ut  he  didn't  reckon  with  the  effects  of  the 
bright  South  Dakota  sun.  With  the  car  parked, 
windows  closed,  all  the  previous  day,  the  crystal 
mike  just  couldn't  take  it.  Having  no  provision 
for  keying  the  rig  or  copying  c.w.,  on  the  mobile 
receiver,  WlHDQ/0  folded  his  beam  and  si- 
lently stole  back  to  Rapid  Cit3^ 

In  the  following  tabulation,  scores  are  listed  by  ARRL 
Divisions  and  Sections.  Unless  otherwise  noted,  the  top 
scorer  in  each  section  receives  a  certificate  award.  Columns

How's  DX? 


CONDUCTED  BY  ROD  NEWKIRK,*   W9BRD 


Why: 

Well  —  1955.  A  new  DX  year  coming  up ! 

We've  instructed  Jeeves  to  go  out  and  pin 
down  the  reasons  for  all  the  wide  smiles  of  high 
DX  morale  prevalent  at  this  writing.  Here's  what 
the  ear-tufted  gentleman  uncovered  in  the  line  of 
facts,  ma'am,  DX  blessings  that  are  no  sorrow  to 
comprehend : 

.  .  .  The  propagational  worm  has  turned  and 
conditions  on  our  higher-frequency  DX  bands  are  on 
a  slow  but  sure  mend.  About  time! 

.  .  .  Fifteen  meters,  our  newest  DX  band  of  vast 
potentialities,  is  about  to  come  into  its  own.  If  any 
band  has  a  chance  to  unseat  Old  Pro  Twenty  as  the 
DX  band,  21  Mc.  is  it.  Indeed,  counting  11  meters,  it 
won't  be  long  before  we  have  four  DX  bands  simul- 
taneously capable  of  producing  rare  daylight  DX. 

.  .  .  There  are  more  ARRL  DXCC  Countries 
List  items  readily  workable  than  ever  before,  this 
despite  the  general  absence  of  U-prefixed  stations. 
Increasing  traffic  at  WlWPO's  Hq.  DXCC  desk 
reflects  this  and  vou'U  be  able  to  prove  it  for  yourself 
next  month  in  the  annual  ARRL  DX  Competition. 
QRV? 

.  .  .  Liberalization  of  amateur  regulations  in  sev- 
eral overseas  countries  during  1954  now  is  evident 
in  the  increasing  number  of  formerly  rare  prefixes 
heard  on  DX  bands.  Austrian,  Japanese  and  Philji)- 
pine  nationals  particularly  benefited.  The  sluggish 
ITU  "ban"  list  which  originally  included  over  a 
dozen  countries  now  is  whittled  down  to  French 
Indo-China,  Indonesia,  Iran,  Korea  and  Thailand. 

.  .  .  TVI  terrors  continue  to  wane.  Guys  who 
surrendered  to  the  one-eyed  monsters  a  couple  of 
years  ago  now  are  back  on  the  air  with  modern 
single-frequency-output  rigs,  working  DX  and  grous- 
ing about  another  nuisance  —  ITV. 

.  .  .  Single-sideband  DX  in  1955  no  longer  is  just 
around  the  corner.  It's  here.  Flip  your  receiver  on 
and  you'll  hear  DXers  eagerly  putting  s.s.b.  to  work 
on  long-haul  A3  paths,  a  facet  of  the  game  attracting 
converts  and  exponents  daily. 

...  A  relatively  new  DX-hunting  gimmick  is 
creating  much  interest  and  finding  wide  acceptance: 
the  "midget"  rotary  beam.  Thoroughly  propounded 
in  1954  QSTs,  these  miniature  squirters  have  given 
cliff  dwellers  a  better  chance  to  slug  it  out  with  the 
antenna-farm  lads,  and  have  made  7-Mc.  rotaries 
highly  practicable. 

That's  enough  detail  to  go  into  in  our  limited 
space.  And  there  you  are,  as  George  Gobel  puts  it. 
You  need  no  rose-tinted  specs  to  diagnose  the 
1955  DX  world  sound,  substantial,  and  rarin'  to 
go.  And,  as  usual,  your  monthly  chunk  of  QST  is 
rarin'  to  record  your  1955  reports  and  contribu- 
tions —  band  by  band,  QTH  by  QTH,  continent 
by  continent,  photo  by  photo  and  cliche  by 
cliche.  Like  this,  for  instance.  .  .  . 

What: 

Fifteen,  as  we  were  saying,  is  coming  along  nicely.

Asia  —  "Activity  in  ZC4  is  on  the  upward  trend  again. 
ZC4GF  is  concentrating  on  160  meters,  50  watts  to  a  half- 
wave  wire;  ZC4CK  is  on  40  meters;  ZC4s  CA  and  PB  are 
on  20  and  40;  ZC4PB  hopes  to  get  on  160  and  ZC4CA  will 
have  a  week  or  two  on  top  band  before  packing  his  sea 
baggage  for  the  U.K.;  ZC4MW  is  temporarily  QRT; 
ZC4IP  is,  I  beUeve,  on  40,  20  and  15;  and  ZC4RH  is  a

desires  to  correspond  with  W  amateurs.  He'll  soon  QSY  to 

the  U.  S.  for  schooling W4TBQ,  active  since  1935

W60ME  as  one  of  TASAA's  1955  operators Ex- 

TA3MP  schedules  an  assault  on  his  Turkey  QSL  backlog,

AA,  Ankara;  US,  Izmir;  WD,  Izmir;  and  TA2EFA,  Ankara, 
still  represent  Turkey  on  ham  bands.  TA3QN  also  is  in

hamshacks  of  VS6AE,  JA8AG  and  KA2CC  were  visited

Africa  —  Illumination  of  Dark  Continental  DX  doings 
thanks  to  ZD6BX:  "ZD6EF  now  is  postmaster  at  Blantyre 
and  is  rebuilding;  he  has  a  low-power  rig  on  40  temporarily. 
VQ5BVF,  active  on  15  'phone,  reports  several  VQ5s  on 
U.K.  leave.  VQ5EK  is  on  20  'phone.  FB8BR  is  a  new  one 
in  Tananarive  with  20  watts  on  20  c.w.  SUIXZ  operates  all 
bands,  160  through  10  meters.  ZS9I  'is  getting  some  QSLs 
off  soon.'  ZS7D  continues  very  active  on  40  c.w."  As  for 
his  own  installation,  Vic  pens:  "ZD6BX  now  is  mainly  on 
15  meters,  with  occasional  forays  on  other  bands."  He  hopes 
to  rack  up  some  3.5-Mc.  DX  this  season  but  b.c.  QRM 
makes  it  necessary  to  operate  around  3600  kc.  ZDGBX's 
power  goes  off  from  2100  to  0400  GMT,  considerably  re- 
stricting night   DX  activities. CN8s   EG   and   FL 

return  home  to  W8s  PHX  and  EZF,  respectively,  where 
they're  willing  to  clear  up  any  outstanding  QSL  matters

teresting DX  award  based  on  30,  25,  20,  or  15  CN8-contact 
QSLs,  the  requirements  depending  on  one's  location.  It's 
called  Diplome  de  V  AAEM.  For  full  details  write  L'  Associa- 
tion des  Amateurs  Emelteurs  du  Maroc,  B.P.  2060,  Casa-

Oceania  —  Hats  off  to  ZKIBG  for  alert  monitoring  and 
quick  action  in  October  when  he  did  much  to  assure  the 
rescue  of  adventurer  Willis  and  balsa  raft  Seven  Little  Sisters 

near  Samoa.- From  the  DXer:  Ex-PK4DA  is  back 

in  Indonesia  for  a  spell  but  reports  little  possibility  of  ham 

activity  there  in  the  near  future .  _  SCDXC  advices: 

VKIHM  and  ZC2AC  are  QRT,  their  silence  to  be  followed 
by  that  of  ZC2AD  who  leaves  the  Cocos  next  month.  Thus 
ZC2-land  joins  Christmas  Island  (ZC3)  in  the  amateurless 
category;  ZC3AB  is  in  Australia  and  ZC3AA  never  ac- 
tivated. Don't  forget  that  G2RO  plans  operation  on  Cocos 
around  February  6th-8th.  F08AG  swapped  islands, 
Makatea  for  Tahiti,  and  VKIAC  returns  to  VK3IB.  The 
ex-F08.4J  team  is  thinking  of  possible  DXpeditioning  in 
the  ZM7  area  next  summer.  VR3A  looks  forward  to  more 
40-  and  80-meter  work  as  well  as  a  1956  visit  to  California. 
VR2BZ  continues  his  RNZAF  flying  visits  to  VR5,  ZM7 
and  other  areas,  firing  up  a  rig  whenever  he  has  the  oppor- 
tunity. ZM7AL  (ZM6AL)  is  intermittently  available  on 
40's  low  edge. 

Europe  —  HVIAA  hit  the  airwaves  far  behind  schedule 
and  QRTd  far  ahead  of  schedule.  W4YHD  reports  that 
only  two  contacts  were  made,   both  of  these  on   14-Mc. 

'phone  (no  Ws) F7s  BM  DH  and  DZ  are  hard  at

0N4ZI  and  YUIGM  (W4GMP)  probably  are  the  only 
Americans  operating  ham  stations  in  their  respective  coun-

Trieste  settlement,  AG2s  and  MF2s  go  off  the  air  in  favor

be  able  to  answer  the  300-plus  pasteboards  RCC  has  re- 
ceived for  CE0AD.  CE0AC  returned  to  Chile  and  will 
QSL  the  few  contacts  he  made.  Conditions  on  Easter  remain 
inhospitable  to  hamming,  the  main  difficulty  being  lack  of 
generator  fuel.

QST  for 


21st  ARRL  International  DX  Competition 

'Phone:  Feb.  llth-13th  and  Mar.  llth-13th; 
C.W.:  Feb.  25th-27th  and  Mar.  25th-27th 


AMATEURS  all  over  the  world  are  cordially  in- 
\  vited  to  take  part  in  the  21st  ARRL  Interna- 
~^^~^  tional  DX  Competition,  to  be  held  four 
week  ends  in  February  and  March.  U.  S.  and 
Canadian  operators  will  be  trying  to  add  to 
their  DX  country  totals,  other  stations  to  work 
needed  states  and  provinces  for  their  WAS  and 
WAVE  awards,  and  everyone  to  match  operat- 
ing skill  with  others  in  his  country  or  ARRL 
section. 

Two  week  ends  are  devoted  to  c.w.  and  two 
to  'phone  operation,  giving  everyone  a  chance  to 
participate  on  both  'phone  and  c.w.  "Rest  up" 
periods  are  provided  between  week  ends. 

The  rules  of  the  contest  are  the  same  as  those 
of  last  year,  with  this  exception:  U.  S.  and  Cana- 
dian amateurs  will  send  a  signal  report  plus  their 
state  or  province  (instead  of  indicating  input 
power).  This  information  is  of  special  interest  to 
overseas  stations  aiming  to  fill  in  states  for  WAS 
and  provinces  for  WAVE. 

As  in  the  past,  certificate  awards  are  offered 
to  the  top  single-operator  'phone  and  c.w.  scorer 
in  each  country  and  ARRL  section.  A  special 
category  recognizes  multiple-operator  stations  in 
those  sections  or  countries  from  which  three  or 
more  valid  multiple-operator  entries  are  received. 
Within  a  club,  single-operator  entries  can  com- 
pete for  the  club  certificate  awards  given  to  the 
highest  c.w.  and  'phone  scorers.  A  handsome 
gavel  is  also  offered  to  the  cilub  whose  members 
run  up  the  highest  aggregate  score. 

Stations  outside  W  (K)  and  VEVVO  will  call 
"CQ  W/VE"  or  "CQ  TEST"  and  trade  contest 
exchanges  with  U.  S.  and  Canadian  participants. 
Those  overseas,  just  as  in  past  years,  will  transmit 
5-  or  6-digit  numbers,  the  first  numbers  indicat- 
ing the  signal  report  and  the  last  three  the  power 
input.  Stations  with  500  watts  input  would  use 
a  power  number  of  500;  those  with  25  watts,  025.

Example:  J.\:i\F,  500  watts  input,  might  send 
"509500"  on  c.w.,  "56500"  on  'phone. 

U.  S.  and  Canadian  amateurs  will  transmit  an 
RS  or  RST  report  plus  (heir  state  or  province,  or 
some  abbreviation  for  the  state  or  province. 
Example:  W2SAI,  New  Jersey,  might  send 
"579XJ"  on  C.W.,  or  say  "57  New  Jersey"  on 
'phone.  Note  that  W  (K)  and  VE/VO  entrants 
will  no  longer  indicate  power  inputs. 

For  purposes  of  conformity,  it  is  suggested 
that  W/VE  C.w.  amateurs  use  this  tabulation  to 
indicate  their  states  or  provinces.  Overseas  oper- 
ators may  use  it  as  a  check-off  Hst  of  states  and 
provinces  worked,  and  for  logging  abbreviations.

no  quotas;  they  will  attempt  to  QSO  as  many 
stations  in  the  19  W  (K)  and  VE/VO  licensing 
areas  as  possible  on  each  band,  160  through  10 
meters. 

Keep  your  log  carefully  and  send  a  copy  of  it, 
in  the  form  shown,  to  ARRL.  Free  contest  forms 
are  now  available  upon  request  from  ARRL, 
West  Hartford,  Connecticut.  Get  your  station 
functioning  at  top  efficiency,  make  no  social 
commitments  for  the  important  week  ends,  read 
the  rules  to  acquaint  yourself  with  the  details, 
and  then  get  set  for  DX  aplenty. 

Rules 

1)  Eligibility:  Amateurs  operating  fixed  amateur  stations 
in  any  and  all  parts  of  the  world  are  invited  to  participate. 

2)  Object:  Amateurs  in  the  continental  U.  S.  and  Canada 
will  try  to  work  as  many  amateur  stations  in  other  parts  of 


Sample  of  report  form  that  must  be  used  by  W/VE 'phone  entrants  and  a// participants  outside  U.  S.  and  Canada, 
'phone  and  c.w.  This  example  is  a  U.  S.  A.  'phone  log.  Foreign  competitors,  of  course,  would  have  reverse  informa- 
tion in   the  "Sent"  and  "Received"  columns;  their  "Received"  column   would  show  exchanges  like  "579CAL," 
5890NT"   (or,  on  'phone,  "46  Vermont,"  "58  Georgia,"  etc.),  indicating  signal  reports  received  and  different 
states  and  provinces  worked;  their  "Sent"  column  would  carry  signal  reports  and  power  indicators  transmitted.

I  certify,  on  my  honor,  that  I  have  observed  all  comjietition  rules  as  well  as  all  regulations  established  for  amateur  radio  in  my  country, 
and  that  my  report  is  correct  and  true  to  the  best  of  my  belief.  I  agree  to  be  bound  by  the  decisions  of  the  ARRL  Award  Committee.

the  world  as  possible  under  the  rules  and  during  the  contest 
periods. 

3)  Conditions  of  Entry:  Each  entrant  agrees  to  be  bound 
by  the  provisions  of  this  announcement,  the  regulations  of 
his  licensing  authority,  and  the  decisions  of  the  ARRL 
Award  Committee. 

4)  Entry  Classifications:  Entry  may  be  made  in  either  or 
both  the  'phone  or  c.w.  sections:  c.w.  scores  are  independent 
of  'phone  scores.  Entries  will  be  further  classified  as  single- 
or  multiple-operator  stations.  Single-operator  stations  are 
those  at  which  one  person  performs  all  the  operating  func- 
tions. Multiple-operator  stations  are  those  obtaining  assist- 
ance, such  as  from  "spotting"  or  relief  operators,  or  in 
keeping  the  station  log  and  records. 

5)  Contest  Periods:  There  are  four  week  ends,  each  48 
hours  long:  two  for  'phone  work  and  two  for  c.w.  The 
'phone  section  starts  at  2400  GMT,  Friday,  Februarj-  11th 
and  Friday,  March  Hth,  ends  2400  GMT,  Sunday,  Febru- 
arj' 13th  and  Sunday,  March  13th.  The  c.w.  section  starts 
at  2400  GMT,  Friday,  February  25th  and  Friday,  March 
25th,  ends  2400  GMT,  Sunday,  February  27th  and  Sunday, 
March  27th. 

6)  Valid  Contacts:  In  the  'phone  section,  all  claimed 
credits  must  be  made  voice-to-voice.  In  the  telegraph 
section,  only  c.w. -c.w.  contacts  count.  Crossband  contacts 
may  not  be  counted. 

7)  Exchanges: 

a)  Amateurs  in  I'.  S.  and  Canada  will  transmit  a  three- 
figure  number,  representing  the  RST  report,  plus  their 
state  or  province.  (The  latter  may  consist  of  an  appropriate 
abbreviation.)  'Phone  participants  will  transmit  a  two- 
figure  number  consisting  of  the  readability-strength  report 
plus  the  state  or  province.  Example:  WIATE  in  Connecti- 
cut might  transmit  "579CONN"  on  c.w.,  "57  Connec- 
ticut "  on  'phone. 

b)  Amateurs  outside  W  (K)  and  VE/VO  will  transmit 
six-figure  numbers,  each  consisting  of  the  RST  report  plus 


three  "power"  numbers;  the  power  indicator  will  repre- 
sent the  approximate  transmitter  power  input.  'Phone 
contestants  will  transmit  five-figure  numbers,  each  con- 
sisting of  a  readability-strength  report  and  the  three 
"power"  numbers.  Example:  VK2EO,  with  100  watts 
input,  might  transmit  ".569100"  on  c.w.,  ".56100"  on 
'phone.  If  the  input  power  varies  considerably  on  different 
bands,  the  "  power  "  number  should  be  changed  accordingly. 

8)  Scoring: 

a)  Points:  One  point  is  earned  by  a  W  (K)  or  VE/VO 
station  upon  receiving  acknowledgment  of  a  contest  ex- 
change sent,  and  two  points  upon  acknowledging  an 
exchange  received.  Two  points  are  earned  by  any  other 
station  upon  receiving  acknowledgment  of  a  contest  ex- 
change sent,  and  one  point  upon  acknowledging  an  exchange 
received. 

b)  Final  Score:  W  (K)  and  VE/VO  stations  multiply 
total  points  earned  under  Rule  8(a)  by  the  number  of  coun- 
tries worked  on  one  band  plus  the  number  of  countries 
worked  on  each  other  band.  All  other  stations  multiply 
total  points  earned  under  Rule  8(a)  by  the  sum  of  the 
number  of  W  (K)  and  VE/VO  licensing  areas  worked  on 
one  band  plus  the  number  of  W  (K)  and  VE/VO  licensing 
areas  worked  on  each  other  band. 

Countries  will  be  those  on  the  ARRL  Countries  List. 
There  are  19  licensing  areas:  10  in  the  L'nited  States,  9  in 
Canada  (VO,  VE1-VE8).  [See  Countries  List  on  p.  60 
and  Footnote  1  on  p.  132  —  Ed.] 

9)  Repeal  Contacts:  The  same  station  may  be  worked 
again  for  additional  points  if  the  contact  is  made  on  a  dif- 
ferent frequency  band.  The  same  station  may  be  worked 
again  on  the  same  band  if  the  complete  exchange  for  a  total 
of  three  points  was  not  made  during  the  original  contact 
on  that  band. 

10)  Quotas:  The  maximum  number  of  points  per  country 
per  band  which  may  be  earned  by  W  (K)  stations  in  the

Proven  Operating  Ability.  Some  test  their 
mettle  as  operators  in  the  "SS"  —  others  have 
a  fine  time  and  roll  up  accomplishments  by  brief 
daily  participation  in  their  Section  traffic  net. 
There's  no  better  way  to  become  an  expert  in 
procedure  and  the  ability  to  copy  accurately. 
The  fullest  enjoyment  of  all  that  amateur  radio 
affords  in  working  DX  and  other  operating 
specialties  goes  hand  in  hand  with  operating 
ability  and  copying  proficiency.  This  month 
we're  glad  to  start  honoring  those  consistently 
turning  in  BPL-dimensional  totals  by  listing 
the  first  to  receive  the  Traffic  Medallions.  See  the 
rules  and  first  announcement  in  August  QST 
if  you  need  more  information.  Any  individual 
amateur  working  at  his  own  station  is  eligible. 

Speaking  of  "copying  down"  ability,  ARRL 
provides  to  all  comers  daily  transmission  of  code 
practice  at  stated  speeds  aimed  at  assisting  new- 
comer and  old-timer  alike  in  knowing  where  he 
stands  on  the  matter  of  copying  ability.  If  not 
ARRL-certified,  be  sure  you  look  for  VVIAW  or 
W60WP  on  their  next  Qualifying  Runs.  Send 
us  what  you  get  to  be  considered  for  certification. 
Don't  stop  with  an  initial  speed  unless  at  the  top. 
Stay  with  us  until  you  have  the  full  set  of  endorse- 
ment stickers.  Prove  to  yourself  and  others  what 
you  can  copy,  and  at  the  same  time  you  will 
have  extended  the  range  of  what  you  can  do  in 
communication  with  amateur  radio.  If  your 
casual  hamming  has  never  gone  ahead  to  include 
DX  countries  and  traffic  ability  along  with  some 
experimenting,  this  can  be  a  suggestion  to  ex- 
pand know-how  and  horizons  in  the  New  Year. 

We've  heard  the  sad  story  of  the  fellow  who 
flunked  the  exam  because  he  "guessed"  he  knew 
enough  to  pass.  Few  that  have  copied  over  the 
air  until  they  got  their  10-w.p.m.  certifications

ever  flunked  the  Novice  Test;  and  few  ARRL-

General  Class  code  test.  The  majority  who  have

(instead  of  maximum)  progress.  We  mention  this 
just  to  suggest,  in  starting  the  year,  that  all 
amateurs  and  amateiw  groups,  including  the 
Novice,  work  for  new  results,  objectives,  and 
top  results,  rather  than  the  minimum,  to  get  the 
most  fun  and  know-how  from  amateur  radio. 

Club  Operating- Versatility  Contest?  This  is 
the  season  of  the  year  when  a  good  many  affiliated 
radio  clubs  are  starting  their  code  and  theory 
classes  (and  holding  examinations)  for  the  club 
members  and  other  community  members  inter- 
ested in  qualifying  for  licenses.  Also,  clubs  are 
announcing  in  many  cases  special  events  —  a 
working  toward  WAS  or  competitions  for  the 
greatest  number  of  DX  QSLs  that  can  be  earned 
and  turned  in  by  club  member  operators  as  of 
some  date  next  spring  —  encouraging  competi- 
tion between  club  members  to  help  them  reach 
these  desirable  goals.  WILLY  comes  forward 
with  an  idea  that  it  would  be  interesting  to  set 
aside  some  designated  week  end  for  a  Versatility 
Contest.  The  idea  would  be  to  credit  all-around 
station  and  operator  ability.  The  "package" 
set-up  in  the  operational  rules  would  establish  a 
quota  to  limit  points  attainable  by  any  one 
means,  or  band,  to  a  sniall  number.  Then  multi- 
pliers  would  be  applied  (1)  for  each  band  worked; 
(2)  each  mode  of  emission  (c.w.,  a.m.,  f.m., 
n.b.f.m.,  f.s.k.-RTTY,  a.f.s.k.-RTTY,  s.s.b.,  fac- 
simile and/ or  TV) ;  (3)  each  mobile  band  operated 
'phone  and  c.w.  (additional  multipliers  to  that 
for  fixed  operation);  (4)  multiplier  for  originating 
one  message;  (5)  multiplier  for  putting  this  into 
section-NTS  net  (each  band  or  mode  used);  and 
(6)  for  working  one  foreign  country  outside  the 
North  American  continent. 

Operating  Calendar  for  the  New  Year. 
The  first  month  of  the  year  is  one  of  the  top  ones 
of  the  season  from  the  standpoint  of  things  to 
do  in  radio  operating.  Stations  can  be  tested, 
states  got  for  WAS  and  other  awards.  There's 
the  V.H.F.  "SS,"  Jan.  8th-9th,  for  the  v.h.f. 
man;  for  the  newcomer  (and  others  to  work  him) 
the  "NR"  runs  from  Jan.  8th-23rd  —  a  few 
QSOs  a  day  and  you  have  it  "made";  appointees 
look  forward  to  their  quarterly  c.w.  and  'phone 
parties  the  week  ends  of  the  15th  and  22nd.  DX 
men  probably  will  be  busy  getting  rigs  and  an- 
tennas ready  for  the  ARRL  DX  Competition 
for  which  scheduled  periods  in  February  and 
March  have  been  announced.  To  attract  the 
foreign  participation  the  W  (K)  and  VE/VO 
contingent  will  identify  their  states  and  provinces 
(helping  the  DX  station  fill  out  working  them 
all!)    following    the    signal-report    part    of    the

OCTOBER  CD  QSO  PARTIES 

Despite  the  depredations  of  Hurricane  Hazel,  which 
roared  up  the  Atlantic  Seaboard  and  left  some  appointees 
nainus  power  and  antennas,  our  c.w.  CD  Party  was  a  highly 
successful  event.  The  notable  e.\ploits  of  top-scorer  \V6MUR 
are  chronicled  with  the  accompanying  photograph.  Another 
Californian,  ORS  \V6BIP,  earned  second  place  with  174,26.5 
points.  Rounding  out  the  top  three,  Assistant  Director 
W4KFC  made  his  customary  impressive  showing  with 
155,295  points.  Sections-worked  honors  were  copped  by 
W6MUR  with  67,  while  VV4KFC  led  in  number  of  contacts 
with  486  in  just  11  hours  .30  minutes  on  the  air. 

An  even  dozen  operators  in  the  'phone  session  turned  in 
scores  over  10,000.  Tops  among  them  was  the  18,150- 
pointer  of  W9KDV,  with  \V9VFY  doing  the  talking.  .\nd 
CD  regulars  W8\0H  and  W4HQN,  both  of  whom  may 
always  be  relied  on  for  outstanding  voice  work,  earned 
second  and  third  positions.  QSO  leader  was  \V9KDV  with 
110,  and  W5j\IFX  worked  the  most  sections,  36. 

The  highest  scores  follow.  Figures  after  each  call  indicate 
score,  number  of  contacts  and  number  of  ARRL  sections 
worked.  Final  and  complete  results  will  appear  in  the 
January  CD  Bulletin.

Any  c.w.  CD  Party  enthusiast  who  hasn't  worked 
this  fellow  lately  better  turn  in  his  receiver  and  head- 
phones! Posting  the  nation's  best  score  in  both  Juiv  and 
October,  GO  Bill  Johnson,  Vt6MLR,  has  really  been 
ritiging  the  bell.  Jfis  tape  fist  and  snappy  operating 
bring  credit  to  the  CD  gang,  as  does  that  crisp-keying 
l)ig  sig"  stemming  from  the  home-brew  450THs  at  the 
right.  Time  was  when  80  meters  was  thought  a  "must" 
as  far  as  amassitig  huge  tallies  was  concerned,  but 
^^6^Il  H  does  FH  on  just  40  and  20:  in  October  he 
stacked  up  4.il  Q.>>Os  in  67  sections  for  a  smashing 
271,9.1,3  points.  Shown  fingering  the  bug  and  bending 
over  the  operating  table,  Bill  portrays  the  traditional 
stance  of  the  inveterate  I)\er.  Indeed,  D\  is  his  main 
interest.  And  if  he  can  again  be  enticed  from  pursuit  of 
-Africans  and  Asiatics,  you'll  see  him  in  the  January  CD!

The  principal  theme  of  letters  being  received  by  your 
NEC  these  days  seems  to  be  complaint  regarding  QRM 
to  emergency  oi)erations  on  75  meters.  Before  we  make 
the  comments  that  we're  going  to  make,  let  it  first  be 
admitted  that  considered  and  impartial  afterthought 
does  not  always  coincide  with  actions  or  attitudes  in  the 
pressure  of  the  moment.  Or,  to  put  it  another  way,  it's 
all  very  well  to  rationalize,  but  not  always  so  easy  to  act 
accordingly. 

It  is  maddening  to  have  someone's  casual  CQ  fcreak 
up  a  message  concerned  with  the  safety  or  life  of  a  person 
or  persons,  and  perfectly  natural  for  one's  thoughts  on 
such  occasions  to  be  along  lines  of  daggers,  machine  guns 
and  gallows.  When  such  QRM  appears  to  be  deliberate 
(very  difficult  to  prove),  and  derogatory  remarks  are 
passed  around  ("tin  soldiers,"  "paper  policemen,"  etc.), 
it  is  indeed  difficult  to  restrain  a  homicidal  impulse;  the 
only  wonder  is  that  all  that  results  are  numerous  letters 
to  us  saying,  in  effect,  that  "there  oughta  be  a  law."  We 
know;  we've  been  through  the  wringer  ourselves. 

But  —  and  here  comes  that  rationalization  —  we  cannot 
help  but  observe  that  the  most  crowded  band  in  the  radio 
spectrum  is  really  not  the  best  suited  for  emergency  com- 
munications purposes.  This  is  especially  true  in  the  eve- 
nings, when  long  skip  conditions  wash  out  local  communi- 
cation almost  entirely  and  bring  in  stations  from  far  away 
loud  and  clear.  By  all  logic,  it  is  ridiculous  to  try  to  pursue 
an  emergency  purpose  under  such  conditions  when  it 
could  be  done  easily,  given  the  proper  equipment,  using 
a  frequency  band  without  such  idiosyncrasies.  Still,  logic 
or  not,  the  guys  are  there,  on  75;  most  of  them  cannot  use 
other  bands,  for  one  reason  or  another,  so  what  are  we 
going  to  do  about  it? 

Several  suggestions  have  been  made.  W4NV  proposes 
establishing  monitoring  frequencies  (3801  and  3995  kc.) 
and  appointment  of  "  National  Emergency  Broadcasting 
Stations"  in  each  state  to  man  the  two  frequencies  during 
any  emergency.  His  plan  is  very  reminiscent  of  our  former 
National  Emergency  Net,  and  reminds  us  to  remind  you 
that  there  still  exists  a  set  of  National  Calling  and  Emer- 
gency frequencies  for  just  such  purposes.  W4ANK,  incensed 
at  QRM  from  stations  participating  in  a  contest  during 
Hurricane  Hazel,  urges  a  national  or  divisional  emergency 
organization  aimed  at  reducing  QRM  on  emergency  fre- 
quencies, automatic  conversion  of  traffic  nets  to  emergency 
nets  during  an  emergency,  and  some  means  of  making 
allowance  for  an  emergency  arising  during  a  contest. 

Certain  provisions  already  e.xist  for  emergencies,  and 
perhaps  before  considering  the  merits  and  demerits  of 
proposals  being  made,  we  ahould  examine  those  which 
now  exist.  Let's  do  this  briefly: 

(1)  FCC  provides  a  measure  of  respite  for  amateurs 
plagued  by  QRM  in  emergencies  in  its  Section  12.156 
of  the  amateur  regulations.  This  is  summarized  in  our  book- 
let Emergency  Communications  (p.  8),  and  outlines  a  pro- 
cedure by  means  of  which  stations  operating  in  an  emer- 
gency may  apply  to  FCC  for  a  "clear  channel." 


(2)  Nets  of  ARRL's  National  Traffic  System  are  under 
instructions  to  activate  themselves  automatically  in  the 
event  of  an  emergency,  to  handle  emergency  traffic  if 
called  upon.  This  procedure  was  described  in  an  Emer- 
gency and  Traffic  Bulletin  some  time  ago,  and  is  due  for 
repetition.  Many  non-NTS  traffic  nets  have  an  agreed- 
upon  procedure  for  automatic  conversion  for  emergency 
purposes. 

(3)  As  mentioned  above,  we  still  have  National  Call- 
ing and  Emergency  Frequencies.  You  will  see  these  listed 
in  a  box  somewhere  in  the  Operating  News  section  of 
QST  each  month  (unless  the  space  problem  is  extremely 
acute,  when  the  editor  usually  finds  room  for  them  else- 
where in  the  issue).  Instructions  for  their  use  are  included. 

The  question  then  is:  what  other  measures  need  be 
taken,  besides  plugging  and  publicizing  jjresent  arrange- 
ments, to  make  our  alertness  for  emergencies  more  wide- 
spread and  instantaneous?  Your  thoughts  on  this  question 
are  solicited.  Just  in  passing,  however,  let's  also  observe 
that  QRM  is  a  quite  natural  phenomenon  when  an  amateur 
band  is  crowded  six-to-a-kilocycle,  and  the  real  solution 
lies  not  in  regimentation  of  our  existing  bands,  but  in 
"selecting  the  channel  to  suit  the  need"  —  a  clause  bor- 
rowed from  Emergency  Communications,  which  more  of 
you  ought  to  read. 

Extensive  flood  conditions  in  Northern  Indiana  and 
Illinois  precipitated  some  activity  among  AREC  groups, 
over  the  SET  weekend  of  October  9-10  and  extending  to 
the  eleventh.  We  have  three  reports: 

(1)  In  La  Orange  Park,  Illinois,  heavy  rains  caused 
backup  of  sewers  and  natural  drainage  into  tlie  streets 
and  basements.  As  the  situation  worsened,  W9JJD  called 
Radio  Officer  W9FKY  and  suggested  some  action  be  taken. 
The  c.d.  radio  group  was  activated,  and  within  a  very 
few  minutes  two  mobiles  were  in  action.  One  of  the  cars 
worked  with  Water  Department  trucks  and  the  other 
one  accompanied  the  fire  engines.  At  1830  that  evening 
as  the  rain  continued  a  third  mobile  unit  was  pressed 
into  action.  Shortly  afterward,  calls  from  alarmed  residents 
became  so  numerous  that  all  three  cars  were  placed  in 
service  answering  them,  each  accompanied  by  one  or 
two  firemen.  All  mobiles  were  kept  extremely  busy,  each 
with  a  backlog  of  calls,  until  after,  midnight.  W9KMT 
and  W9MAT  also  participated  in  this  activity. 

(2)  The  Calumet  Area  Emergency  Net  was  called  into 
action  on  October  11  by  request  of  Hammond  (Ind.)  city 
officials  as  the  Little  Calumet  River  went  on  a  rampage 
due  to  heavy  rains.  The  Lake  County  Amateur  Radio 
Club  station,  W9ZKW,  was  set  up  at  the  Hammond  City 
Hall,  with  W9GRA/9  at  the  Woodmar  Country  Club 
in  the  middle  of  the  flood  area.  Other  fixed  portable  stations 
assisting  were  W9CWO/9  at  Highland,  W9PVQ/9  at 
Black  Oak,  W9SNF/9  at  Hammond  and  W9RWN  at 
East  Hammond.  EC  W9KRJ  monitored  and  assisted  in 
clearing  the  f  recjuencv.  MoV)iles  operated  on  1805  kc.  and  in- 
cluded W9s  KRJ  pVq  IFC  DRJ  DWF  JZA  IBZ  WFI 
MNO  DDK  UXK  RXB  MOC  EHY  UVR  WTW  ZJH 
and  APO. 

(3)  In  Indiana,  the  towns  of  Plymouth  and  Knox  were 
hard  hit.  In  Plymouth,  EC  W9AYP  set  up  communication 
facilities  at  tliat  point,  assisted  by  W9ATT  and  W9LDJ 
with  W9JWI  of  (Tulver  also  assisting.  Both  the  Michiana 
Radio  Club  and  the  Mobile  Amateur  Club  of  St.  Joseph 
County  participated,  the  former  keeping  W9AB,  the 
Red  Cross  station  of  South  Bend,  on  the  air.  The  Indiana 
Phone  Net  also  greatly  assisted  by  relinquishing  the  net 
frequency  for  emergency  traffic  when  the  occasion  war- 
ranted. Later,  a  call  came  from  Knox  that  help  was  needed 
in  communications.  Eight  mobile  units  with  two  base 
station  operators  were  formed  into  two  groups,  one  for 
immediate  use  and  the  other  to  furnish  relief  when  needed. 


One  of  the  most  active  mobile  emergency  groups  in 
the  country  is  the  Philmont  Mobile  Radio  Clnb. 
W3JGB  is  NCS  of  the  weekday  ".Scrambled  Egg  Net" 
on  29,493  kc.  Everyone  or  anyone  is  invited  to  drop 
in  on  this  frequency  to  say  hello. 


QST  for 


The  problem  at  Knox  was  protection  of  the  local  disposal 
plant  from  rising  waters.  The  Mobile  Amateur  Club  of 
St.  Joseph  County  furnished  the  equipment  and  personnel. 
The  c.d.  base  station,  W9UB,  at  South  Bend,  acted  as 
a  base.  W9YEA  of  Knox  did  most  of  the  organizing  as 
EC.  W9AYP,  \V9JWI  and  W9YEA  went  many  long  hours 
without  sleep  in  helping  out. 

Others  not  mentioned  above  who  also  assisted  included 
W9s  GAV  DDE  UZP  AQA  AQB  YME  ZIB  CC  JEG 
EKK  ECH  QWI  EHZ  AWN  SXT  QXF  EOG  YRF  LVS

NAR  BRR  EZS. 

On  August  1.5th,  the  Red  Cross  in  four  Florida  counties 
held  a  hurricane  drill  in  which  amateurs  actively  partici- 
pated. Many  stations  throughout  the  Eastern  Florida 
section  gave  assistance,  and  stations  out  of  state  assisted 
in  relaying  traffic  to  Atlanta  and  Washington.  The  counties 
involved  were  Palm  Beach,  Broward,  Dade  and  Monroe, 
an  area  in  which  reside  an  estimated  800  amateurs  and 
in  which  197  amateurs  are  registered  in  the  AREC.  Eastern 
Florida  SEC  W4IM  records  7.3  stations  as  having  partici- 
pated, 21  of  them  mobile,  in  this  well-planned  and  extensive 
exercise. 


The  AREC  of  De  Kalb  County,  Georgia,  on  the  Labor 
Day  week-end  repeated  their  .July  4th  performance  for  the 
Red  Cross  by  assisting  in  rendering  aid  to  accident  victims 
in  the  general  vicinity  of  the  intersection  of  Highways 
12  and  78  near  Avondale,  Ga.,  reputed  to  be  one  of  the 
worst  places  for  highway  accidents.  On  Friday  night  75 
meters  was  used,  but  QRM  and  QRX  hampered  operations, 
so  on  Monday  the  mobiles  were  shifted  to  ten  meters. 
Contact  was  maintained  mobile  to  mobile  and  with  fixed 
stations  set  up  at  police  headquarters.  Seven  accidents 
occurred  within  one  two  hour  period,  three  of  them  re- 
quiring first  aid  and  one  involving  three  cars  requiring 
ambulance  service.  Red  Cross  personnel  were  standing 
by  at  the  police  stations  to  rush  to  the  scene  wherever 
need  was  reported  by  the  mobiles.  Twelve  operators 
participated  in  this  "Operation  Bandaid";  W4s  NS  PUM 
MV  EPM  IPL  ZUF  LXR  SOV  RVH  PDD  FKE  UMO. 


Members  of  the  Blossomland  .\mateur  Radio  Associa- 
tion of  St,  .loseph,  Mich.,  assisted  the  Berrien  County 
Sheriff  Department  in  providing  mobile  communication 
during  the  heavy  traffic  period  over  the  Labor  Day  Week- 
end. The  main  control  station  was  set  up  at  the  Sheriff's 
office,  using  W8MAI/8.  Alternate  control  stations  at 
strategic  points  around  the  countrv  were  W8s  FGB/8 
SCS  and  RAE.  Mobiles  were  W8s  FGB  JFW  MWO  JUA 
SCS  MVO  BKL  QBN  HKT  XSA  QQO  FBV  GTM  and 
QFV.  The  boys  operated  in  eight  hour  shifts,  five  units 
in  service  at  a  time.  A  regular  uniformed  Deputy  Sheriff 
was  assigned  to  each  mobile  to  perform  regular  police 
duties.  The  fre(iuencj'  used  was  1890  kc.  Other  participants 
were  W8s  MXI  PQI  ORM  CRD  YKS  and  WN8QOD. 

Another  Labor  Day  exercise  was  the  furnishing  of  radio 
communication  for  the  annual  Pikes  Peak  races  by  Colo- 
rado Springs  EC  W0TV  and  his  gang.  The  group  loaded 
up  their  field  gear  in  WBMJD's  truck  and  took  off  at  0.30J 
on  September  6th.  Individuals  were  assigned  posts  along 
the  winding  road  to  the  summit,  ten  of  them  in  all,  to 
report  every  racer  by  number  as  he  passed  his  post.  W0WPK 
was  at  the  starting  line,  W0HEM  at  Post  1  and  W0EYX 
and  W5BTI/0  at  the  summit,  operating  on  29.624  kc. 
for  the  purpose  of  passing  official  orders  as  re.iue.sted. 
The  otliers  operated  on  388.5  kc.  as  follows:  Starting  line 
and  NCS— W0SDW;  Post  1  — W2IMC:  midway  be- 
tween Post  1  &  2  — W0AXX;  Post  2  — W0HHR;  Post 
3  —  W0PBN ;  Post  4  —  W0M JD ;  Post  .5  —  WOCA'G ;  Post 
6  — W0CVG;  Post  7  —  W3MFF;  Post  8  —  W0QQX;  mid- 
way between  Posts  8  &  9  —  W0JMB;  Post  9  —  W0MEY; 
Post  10  (summit)  —  W0PTR  and  W0VCZ.  W0TV  was 
standby  on  either  band  at  the  starting  line,  operating; 
with  his  receiver  on  the  PA  system  so  that  observers  at 
the  starting  line  could  trace  the  racers  to  the  summit. 

Our  SECs  are  improving  greatly  in  the  matter  of  re- 
porting. For  the  month  of  September,  seventeen  SEC  re- 
ports were  received,  representing  activities  of  42.56  AREC 
members,  and  three  new  sections  have  been  added  to 
this  year's  reporting  roster:  Arizona,  Louisiana  and  Ver- 


mont. The  September  record  this  year  tops  that  of  both 
1953  and  1952,  and  the  total  number  of  sections  for  the 
year  is  now  28,  compared  to  22  in  1953  and  29  in  19.52. 
We're  also  ahead  of  last  year  in  total  number  of  reports 
(135  to  114),  but  trailing  our  1952  record  of  157  at  this 
time. 

Let's  keep  those  reports  coming  in,  fellows! 

MEET  THE  SCMs 

Thomas  J.  Morgavi,  currently  serving  the  Louisiana  sec- 
tion in  the  capacity  of  SCM,  was  issued  his  first  license  in 
1935  with  the  call  he  now  holds,  W5FM0. 

A  former  Official  Relay  Station  and  Official  'Phone  Sta- 
tion, he  is  presently  an  Official  Observer.  Since  his  par- 
ticipation several  years  ago  in  a  Frequency  Measuring  Test 
with  a  home-built  Wien  bridge,  he  has  become  extremely 
interested  in  frequency  measurement  and  has  built  a  second- 
ary standard,  cycle  counter,  and  other  associated  equip- 
ment. SCM  Morgavi  is  active  in  the  Greater  New  Orleans 
Amateur  Radio  Club  and  is  trustees  of  the  club  station. 


W5L'K.  Two  Public  Service  certificates  have  been  issued  to 
him  for  his  work  in  the  1947  Florida  Peninsula-Gulf  Coast 
Hurricane  and  the  Big  Freeze  of  February,  1951.  He  likes 
to  handle  traffic  for  overseas  stations  on  ^L\RS  frequencies. 

W5FMO's  station  layout  consists  of  push-pull  810s  in  the 
final  modulated  by  push-pull  80.5s,  600  watts  on  'phone  and 
c.w. ;  also  a  low-power  BC-610  exciter,  75  watts  'phone  and 
c.w.  Receiver  is  an  HQ-120.  Antennas  include  an  80-  and 
40-meter  vertical,  a  three-element  20-meter  rotary  beam, 
and  a  Marconi  for  the  small  rig.  All  bands  160  through  15 
meters,  'phone  and  c.w.,  are  used. 

Tom  expects  to  be  successful  in  the  near  future  in  induc- 
ing his  XYL,  Helen,  to  get  her  ham  ticket.  Baseball  and 
boxing  are  his  favorite  sports.  The  Corps  of  Engineers,  U.  S. 
Army,  has  employed  him  as  radio  operator  and  radio 
service  en^dneer  since  1940.

TRAFFIC  TOPICS 

What's  in  a  name?  Anions  tlie  luaidreds  of  nets  registered 
in  the  ARRL  Net  Directory,  some  call  themselves  traffic 
nets  and  some  emergency  nets,  but  in  actual  practice  the 
traffic  nets  frequently  mobilize  in  an  emergency,  and  the 
emergency  nets  usually  handle  traffic  in  their  drills  and  test 
—  and  always  during  the  real  thing.  A  good  gen  ral  rule  in 
that  a  traffic  net  should  be  an  emergency  net  as  well,  and  an 
emergency  net  should  also  be  a  traffic  net.  The  designation 
as  one  or  the  other  is  to  indicate  the  principal,  not  the  only, 
dedication. 

That  the  emergency  net  should  know  how  to  handle  traf- 
fic (and  that  means  doing  it  as  a  matter  of  course)  is  incon- 
testable. This  is  not  to  say  that  they  all  do  know  how  to 


handle  traffic,  only  that  few  people  if  anyone  will  argue 
that  they  should.  We  think  that,  generally  speaking,  emer- 
gency nets  are  better  versed  in  the  handling  of  traffic  than 
traffic  nets  are  in  organization  for  emergencies.  And  that 
brings  us,  finally,  to  the  subject  for  this  column  this  month; 
that  every  traffic  net  should  have  an  emergency  plan. 

Many  already  have.  We  can't  mention  them  all,  but  more 
power  to  those  traffic  nets  which  have  swung  into  action  in 
emergencies,  and  even  more  power  to  those  which  have  a 
plan  for  doing  so.  On  the  other  hand,  a  good  many  of  them 
liandle  only  routine  traffic  and,  in  an  emergency,  find  them- 
selves on  the  outside  looking  in  —  looking  for  a  place 
wherein  they  may  be  of  assistance. 

The  National  Traffic  System  has  a  policy  for  emergency 
operation  which  was  set  down  in  an  Emergency  and  Traffic 
Bulletin  dated  Spring,  1950.  Its  salient  points  bear  repeat- 
ing. During  an  emergency,  NTS  nets  should  be  self-acti- 
vating; that  is,  they  should  be  able  to  swing  into  action  or 
take  care  of  an  emergency  situation  in  any  alTected  area. 
NTS  nets  in  surrounding  areas  should  be  activated  to  take 
care  of  outside  communications  if  and  when  called  upon. 
Depending  upon  the  urgency  involved  and  the  volume  of 
emergency  traffic,  official  or  otherwise,  the  not  manager  con- 
cerned must  determine  whether  his  net  in  any  particular 
situation  shall  handle  official  traffic  only,  all  emergency 
traffic,  or  all  traffic  as  usual.  In  most  cases  it  will  be  possible 
to  handle  all  types  of  traffic  but  to  give  precedence  to  official 
emergency  traffic  in  view  of  its  inherent  public  interest  and 
importance. 

Tlie  extent  of  NTS  activation  in  emergencies  will  depend 
entirely  on  the  extent  of  the  emergency.  If  a  local  flood,  the 
section  traffic  net  will  probably  be  adequate,  with  activation 
of  the  regional  net,  if  required,  to  handle  outside  contact.  If 
tlie  emergency  extends  over  several  states  or  ARRL  sec- 
tions, probably  the  regional  net  should  be  activated  in  addi- 
tion to  section  nets,  with  "shuttle  liaison"  from  one  to  the 
other,  and  possible  activation  of  the  area  net  to  provide 
outside  contact.  If  the  emergency  is  area-wide,  all  NTS  nets 
within  that  area  should  be  on  the  job,  with  possible  activa- 
tion of  an  adjacent  area  net  to  provide  outside  contact. 

There  is  much  more  to  this  subject  of  using  traffic  nets  for 
emergency  purposes  than  can  be  discussed  here  and  now. 
We  simply  wish  to  point  out  that  it  is  not  a  new  idea,  and  to 
renew  the  thought  that  traffic  nets  have  an  emergency  ap- 
plication, and  that  ECs  should  know  of  traffic  affiliations  of 
any  of  their  AREC  members  for  possible  use  in  emergencies. 
And  you  net  managers  —  have  you  a  plan  for  operation  in 
emergencies?  Better  give  it  some  thought. 

Three  miscellaneous  October  net  reports:  (1)  The  Early 
Bird  Net  reports  traffic  amounting  to  686.  (2)  The  North 
Texas  —  Oklahoma  Section  Net  held  31  sessions,  1010 
check-ins  and  a  traffic  count  of  319.  (3)  The  Transconti- 
nental Phone  Net  registered  782  message  counts  with  eleven 
stations  participating  in  the  First  Area. 


National  Traffic  System.  NTS  has  a  place  for  every  traffic 
man  if  said  traffic  man  has  a  place  in  his  inclinations  for 
NTS.  The  System  is  built  on  the  basis  of  the  "bestest  for 
the  mostest."  Any  amateur  who  really  wants  to  participate 
may  do  so,  and  welcome.  This  includes  old  shellbacks  who 
can  copy  4.5  w.p.m.  with  a  four-inch  paint  brush  down  to  the 
newest  Novice  who  had  to  hump  to  get  past  five  w.p.m. 

But  this  does  not  mean  that  you  may  participate  at  any 
level  you  please.  NTS  has  many  levels,  and  each  participant 
must  find  his  own  —  section  novice  or  training  nets  for  rank 
beginners,  section  traffic  nets,  regional  nets,  area  nets  and 
the  Transcontinental  Corps  —  depending  on  such  factors  as 
experience,  dependability,  and  aptitude.  We  have  been 
sniped  at  for  this  policy,  but  we  still  think  it's  a  good  one. 
The  system  was  not  set  up  to  serve  any  individual  or 
organization,  but  to  serve  amateur  radio  by  creating  an 
organized  nationwide  service. 

Of  course  it  does  not  always  work  as  planned;  even  major 
leaguers  never  bat  1.000.  It  you  are  not  participating, 
naturally  you  are  hurting  NTS,  especially  if  you  are  one  of 
the  experienced  traffic  men  we  need  to  make  it  work.  But 
we'll  do  what  we  can  with  what  we  have,  and  hope  that  the 
system  will  continue  to  show  improvement  through  the 
years  as  traffic-handling  amateurs  learn  that  there  is  pleas- 
ure to  be  had  in  operating  as  part  of  a  team. 

An  announcement:  effective  November  15,  1954,  the 
ARRL  National  Traffic  System  officially  adopted  a  six-day 
week.  Many  NTS  nets  already  have  been  operating  on  Sat- 


72 


QST  for 


urdays  and  others  e.xpanded  their  .schedules  to  cover  Sat- 
urday at  our  suggestion.  Some  are  finding  it  difficult  to  ob- 
tain Saturday  NCSs  and  liaison  stations  (volunteers  needed). 
Generally  speaking,  however,  there  will  no  longer  be  that 
crucial  48-hour  period  from  Friday  to  Monday  that  NTS 
does  not  function.

Connecticut,  New  Hampshire  and  Western  Mass.  get 
stars  for  perfect  attendance  on  the  IRN  report.  3RN 
started  operating  a  se.ssion  at  1830,  starting  November  15. 
W40GG  has  taken  the  reins  as  manager  of  RN5,  and 
VE7ASR  is  the  new  manager  of  RN7;  we  wish  them  both 
the  best  success.  W8DSX  says  the  second  session  of  8RN  is 
not  very  well  attended.  VE3GI  commends  VE3AJR  for  her 
performance  on  TRN.  W8SCW  says  he  is  still  trying  to  get 
out  an  EAN  bulletin.  CAN  certificates  have  been  issued  to 
W5CAF,  W5MXQ  and  W4TYU;  Peggj-  is  having  trouble 
getting  NCSs  for  CAN.  If  interested,  drop  her  a  line  or 
radiogram.  A  PAN  certificate  has  been  issued  to  W6ZRJ; 
W7NH  is  back  at  the  helm  of  PAN. 

The  TCC  roster  is  gradually  filling  up,  but  some  of  the 
long  haul  schedules  are  having  difficulty  with  conditions  so 
screwy.  What  we  ought  to  have  are  raidwestern  relays  to 
stand  in  on  the  schedules.  Anyone  want  to  be  considered  for 
that  role  once  or  twice  per  week? 

WlAW  OPERATING  SCHEDULE 

{All  limes  given  are  Eastern  Standard  Time) 

The  WlAW  Fall-Winter  operating  schedule  remains  in 
effect.  Master  schedules  showing  complete  WlAW  opera- 
tion in  EST,  CST  or  PST  will  be  sent  to  anyone  on  request. 

Operating-  Visiting  Hours: 

Monday  through  Friday:  1500-0300  (following  day). 

Saturday:  1900-0230  (Sunday).  Sunday:  1500-2230. 

Exceptions:  WlAW  will  not  observe  its  regular  hours 
from  0300  Jan.  1st  to  1500  Jan.  2nd  and  from  2230  Feb.

a  chart  to  determine  times  during  which  WlAW  engages  in 
general  operation  on  various  frequencies,  'phone  and  c.w. 
This  schedule  is  still  in  effect  but  is  not  reproduced  herewith 
for  space  considerations.  Note  that  since  the  schedule  is 
organized  in  EST,  certain  morning  operating  periods  may 
fall  on  the  evening  of  the  previous  day  in  western  time 
zones.  Wl.AW  will  participate  in  all  official  ARRL  operat- 
ing activities,  using  scheduled  general  operating  periods  for 
this  purpose  if  necessary. 

Official  ARRL  Bulletin  Schedule:  Bulletins  containing 
latest  information  on  matters  of  general  amateur  interest 
are  transmitted  on  regular  schedules: 

Frequencies  (kc): 

C.W.:  1885,  3555,  7125,  14,100,  21,020,  52,000,  145,600.

transmissions  will  be  replaced  by  Code  Proficiency  Qualify- 
ing Runs  on  January  14th  and  February  14th,  and  by  a 
Frequency  Measuring  Test  on  February  8th. 

BRIEF 

Ray  Grob,  jr.,  W8YFJ,  President  of  Sandusky  Valley 
.Amateur  Radio  Club,  reports  that  a  Mobile  Caravan  held 
July  18th,  sponsored  jointly  by  the  Toledo  Radio  Club, 
Toledo  Mobile  Radio  Club  and  SV.'VRC,  was  a  big  success. 
A  caravan  of  160-meter  mobiles  started  out  from  Toledo 
on  a  tour  through  the  SVARC  area,  including  Port  CUnton, 
Fremont,  and  Woodville,  Ohio.  At  their  home  stations  the 
members  of  SVARC  formed  a  net  and  worked  the  mobiles 
one  by  one  as  they  passed  through  the  area.  In  this  manner 
the  Toledo  boys  qualified  for  the  SVARC  honorary  mem- 
bership award  by  working  five  or  more  members,  and  the 
SVARC  gang  qualified  for  the  WTO  award  by  working 
fifteen  Toledo  stations.  QRM  was  non-existent  due  to  strict 
maintenance  of  net  discipline.

November  1,  1954  will  be  credited  for  DXCC,  but  con-

CODE  PROFICIENCY  PROGRAM 

Twice  each  month  special  transmissions  are  made  to 
enable  you  to  qualify  for  the  ARRL  Code  Proficiency  Certif- 
icate. The  next  qualifying  run  from  WlAW  will  be  made 
on  January  14th  at  2130  EST.  Identical  texts  will  be  sent 
simultaneously  by  automatic  transmitters  on  1885,  3555, 
7125,  14,100,  21,020,  52,000  and  145,600  kc.  The  next 
qualifying  run  from  W60WP  only  will  be  transmitted  on 
January  7th  at  2100  PST  on  3590  and  7138  kc. 

Any  person  may  apply;  neither  ARRL  membership  nor 
an  amateur  license  is  required.  Send  copies  of  all  qualifying 
runs  to  ARRL  for  grading,  stating  the  call  of  the  station 
you  copied.  If  you  qualify  at  one  of  the  six  speeds  trans- 
mitted, 10  through  35  w.p.m.,  you  will  receive  a  certificate. 
If  your  initial  qualification  is  for  a  speed  below  35  w.p.m., 
you  may  try  later  for  endorsement  stickers. 

Code-practice  transmissions  will  be  made  from  WlAW 
each  evening  at  2130  EST.  Speeds  are  15,  20,  25,  30  and 
35  w.p.m.  on  Monday,  Wednesday  and  Friday,  and  5,  7M.

Saturday.  Appro.ximately  10  minutes'  practice  is  given  at 
each  speed.  References  to  texts  used  on  several  of  the  trans- 
missions are  given  below.  These  make  it  possible  to  check 
your  copy.  For  practice  purposes  the  order  of  words  in 
each  line  of  QST  text  sometimes  is  reversed.  To  get  send- 
ing practice,  hook  up  your  own  key  and  buzzer  and  attempt 
to  send  in  step  with  WlAW.

KENTUCKY  — SCM,  Robert  E.  Fields,  W4SBI — 
Looks  like  JUI  is  our  No.  1  station  with  an  00  appointment. 
He  is  working  on  the  6-  and  2-meter  rig  and  already  has 
receivers  and  standards  for  tiiose  bands.  CDA  has  a  very 
potent  'phone  signal  on  75  meters  now,  the  first  time 
on  'phone  since  he  got  his  ticket  in  1930.  SYD  says  skip  is 
causing  him  no  end  of  trouble  handling  traffic  on  KYN. 
WN4GTC  is  asking  for  information  about  a  Novice  net  on 
80  meters.  WNH  has  a  32-element  beam  up  for  2  meters,  but 
blew  up  a  relay  on  the  big  rig,  temporarily  curtailing  opera- 
tion on  80  meters.  K4FBW  has  completed  a  6146  parallel 
final  and  is  rebuilding  an  exciter.  KKW  is  working  the  traffic

leader  in  the  amateur  transmitter  field. 

operating  the  Viking  Kilowatt  is  a  never-to-be  forgotten  experience . . . 

you'll  marvel  at  the  ease  of  selecting  SSB,  AM,  or  CW  with  the  flip 

of  a  single  switch . . .  you'll  enjoy  the  convenience  of  its  desk  top 

trols ...  and  you'll  immediately  sense  the  authority  of  its  full  kilowatt 

signal  lifting  you  into  a  select  group  of  leading  amateurs . . . 

commanding  the  admiration  of  all.  You'll  be  delighted,  too,  knowing 

that  all  this  can  be  yours  at  an  unbelievably  low  price.  This  Viking 

stands  alone  as  a  crowning  achievement  in  all  things  that  make  a 

perfectly  engineered  kilowatt  a  pleasure  to  own  and  operate.

from  you  often.  ELW  made  BPL  again  this  month;  our 
only  one.  Looks  like  Seth  is  going  out  after  that  award  in 
earnest.  MQH  and  OQH  are  new  NCS  on  QMN,  and  have 
been  doing  very  well.  FX  is  battling  power-Une  noise  in  the 
receiver,  and  thinks  he  has  it  licked.  MGQ  has  moved  to 
Huntington  Woods,  so  won't  be  heard  (except  on  mobile) 
for  a  month  or  so.  DLZ  reports  a  new  "wind  direction 
indicator"  on  his  garage  roof.  He  says  his  40-meter  vertical

taken  over  the  radio  class  in  the  .\dult  Education  Program 
at  High  School.  The  Motor  City  Club  has  a  new  and  very 
interesting  club  bulletin.  The  Hard  Luck  .A.ward  of  the

could  in  order  to  avoid  powerline  QRM,  etc.,  and  now  the

THE    HQ-140-X 


SEEMS  TO  STRETCH  THE  BANDS 


In  these  days,  when  the  amateur  bands 
are  more  crowded  than  ever,  it's  im- 
portant to  make  sure  the  receiver  you 
buy  will  bring  in  the  desired  signal  with 
minimum  interference  from  adjacent 
channels.  That's  why  more  and  more 
'hams'  are  turning  to  the  HQ-140-X 
communications  receiver. 

The  HQ-140-X's  outstanding  perform- 
ance under  today's  difficult  operating 
conditions  is  achieved  because  of  the 
Hammarlund  patented  455Kc  crystal 
filter  and  phasing  network.  This  circuit, 
identical  to  the  one  used  in  the  Super 
Pro-600-JX  professional  receiver,  is  con- 
trolled by  a  front  panel  6-position 
Crystal  Selectivity  switch  and  provides 


an  OFF  position  and  five  increasingly 
selective   bandwidths. 

The  Crystal  Phasing  control  is  a 
differential-type  variable  air  capacitor 
which  permits  precise  adjustment  of  the 
crystal  selectivity  for  extremely  high  at- 
tenuation of  closely  adjacent  channel 
interference. 

Because  there  is  no  interlocking  effect, 
the  Selectivity  or  Phasing  Controls  can 
be  changed  without  de-tuning. 


THE  HQ-140-X  IN  ACTION  AT  SEA 

The  HQ-140-X  is  the  receiver  in  the  radio 
shacks  of  many  American  Merchantmen.  Its 
dependability  and  ruggedness  make  it  very 
popular  with  seagoing   hams. 


Get    the     details     on    these     and     other    Important    advantages     of     the     HQ-140-X.     Write     to 
The  Hammarlund  Manufacturing  Co.,  Inc.,  460  W.  34th  St.,  New  York  1,  N.  Y.  Ask  for  Bulletin  Rl.

ANTENNA  COUPLER 

KIT 

The  new  Heathkit  An- 
tenna   Coupler    Model 
AC-1   was  specifically 
designed  to  operate  with 
the  Heathkit  Amateur 
Transmitter  and  will 
operate  with  any  trans- 
mitter not  exceeding  75 
watts  RF  input  power. 
Rugged  design  has  resulted 
in  a  sturdy,   well  shielded 
unit  featuring  a  copper  plat- 
ed chassis  and  shield  com- 
partment. Coaxial  52  ohm 
receptacle  on  the  rear 
of  the  chassis  connects 
to  a  three  section  Pi-  type  low  pass 
filter  with  a  cut-off  frequency  of  36  Mc. 
Tuning  network  consists  of  a  variable 
capacitance  and  tapped  inductance  in 
an    impedance    matching    unit. 
Capacity  coupled  neon  lamp 
serves  as  a  tuning  indicator 
and  will  also  provide  a 
rough    indication 
of  power  output.

MALLORY  HAM  BULLETIN 


MALLORY 
6  -Volt 


Battery  Charger 


Keeps  Mobile  Unit  on  the  Go 


Those  of  IIS  who  liave  tried  mobile  operation 
are  fully  aware  of  the  very  diffi<iilt  problem 
of  how  to  keep  the  car  Itattery  charged 
adequately  for  starting  purposes,  and  still 
provide  plenty  of  juice  for  a  reasonable 
amount  of  time  on  the  air. 

Recently,  one  of  our  good  amateur  friends, 
who  is  a  red-hot  mobile  fan,  told  us  of  a 
method  he  used  for  keeping  his  battery  at 
top  performance  and  still  add  no  extra  equip- 
ment to  his  automobile.  His  system  sounded 
so  practical,  that  we'd  like  to  pass  it  along. 

Here  is  what  he  did.  First,  he  visited  his 
Mallory  distributor  and  bought  a  small, 
inexpensive  Mallory  6-volt  Batterv  Charger 
(the  6SAC6  or  12SAC5  for  12-volt  systems) 
together  with  a  special  automobile  Cigarette 
Lighter  Plug  (Mallory  R675)  to  be  used  for 
inserting  the  Charger  output  into  the  elec- 
trical circuit  of  his  car.  The  Lighter  Plug  w  as 
attached   to   the   Battery    Charger   and    the 


P.  R.  MALLORY  &  CO.  Inc. 

P.O.  Box  1558 
INDIANAPOLIS  6  INDIANA 


whole  business  was   then    mounted    con- 
veniently in  his  garage. 

After  an  evening  of  mobile  operation,  he 
simply  inserted  the  Plug  into  the  cigarette 
lighter  socket,  turned  on  the  117  VAC  line, 
and  the  next  morning,  presto,  his  battery 
was  ready  for  heavy  starting  action. 

With  this  very  convenient  arrangement,  this 
ham  was  able  to  operate  his  mobile  rig  the 
year  'round,  with  little  fear  of  even  tough 
wintertime  starting. 

Incidentally,  if  your  car  is  not  equipped  with 
a  cigarette  lighter,  don't  let  that  handicap 
y  ou,  simply  ask  your  distributor  for  a  Mallory 
Dashboard  Receptacle  (R652)  which  may  be^ 
clamped  to  the  dashboard  without  drilling 
a  single  hole.  Lsed  in  conjunction  with  a 
Cord  Assembly  (R670)  this  arrangement  will 
provide  all  the  convenience  afforded  by  the 
lighter  plug  method  of  installation.

ciency and  Minimum  SWR. 

The  Calibrated  R-F  Wattmeter  simplifies 
tuning  of  all  r-f  stages  and  enables  proper 
adjustment  of  circuit  elements  and  voltages  for 
Maximum  Power  Output  up  to  125  watts  and 
higher  powers  by  sampling  methods. 

A  built-in  non-Reactive  Dummy  Load  enables 
you  to  perform  numerous  Tuning  and  Adjust- 


ment Tests — without  Putting  a   Signal   on  the 
Air. 

Now  you  can  moke  all  of  these  highly  impor- 
tant measurements  and  tests  with  this  one 
instrument.  The  results  will  amaze  you  and 
you'll  wonder  how  you  ever  got  along  without

secy.;  and  Harry  Witzke,  treas.  Harry  always  keeps  the 
books  in  the  black  instead  of  red.  Altliough  it  was  thought 
best  for  the  club  to  change  officers  every  two  terms  we 
couldn't  spare  Harry.  The  HAMS  have  decided  to  go  on 
6  meters.  Tliose  interested  and  new  members  are  expected 
to  join  the  group.  The  San  Francisco  Naval  Shipyard  Club 
is  busily  making  plans  for  the  Christmas  Dinner  to  be  held 
at  the  Naval  Shipyard.  AJF,  of  Sonoma,  is  busy  rebuilding 
tlic  rig,  is  doing  additional  work  on  tlie  2-meter  beam  design, 
and  lias  completed  a  new  v.h.f.  receiver.  The  29ers  lost  FVK 
to  I'ncle  Sam.  Gordon  was  a  very  faitliful  net  control  on 
10-uieter  transmitter  hunts  and  always  Johnnj'-on-the-spot 
for  c.d.  drills.  SLX  was  stationed  at  Treasure  Island  during 
( )it()ber.  Friends  saw  him  at  the  San  Jose  Hamboree  but 
lie  nnist  have  had  very  little  free  time  as  he  never  showed 
up  at  any  of  the  local  amateur  club  meetings.  Ed  said  he  was 
taking  notes  from  the  Bay  Area  back  to  Eureka  with  him. 
The  14  Mobileers  and  their  families  took  a  trip  uij  to  Carson 
City,  Nev.,  to  handle  communications  for  the  Admission 
Day  Parade.  EJY  acted  as  net  control  in  his  new  Oldsmo- 
bile.  CTH  sat  at  the  judges'  stand,  acted  as  relay  station, 
and  watched  all  the  Vjeautiful  girls  as  they  marched  by. 
GGC  had  the  portable  Elmac  rig  set  up.  ISO  helped  set  up 
tlie  antenna  and  the  XYLs  made  corrections,  omissions,  and 
additicms  on  the  parade  sheets  for  the  announcer.  Oh,  yes, 
tlicy  also  called  tlie  two  amateurs  to  attention  when  the

A  Note  About  Crystal  Tolerance: 

In  the  manufacture  of  cryitals,  certain  limits  must  be  adhered  to  when  finishing  the  unit.  Such 
limits  are  often  held  to  better  than  .001%  for  commercial  applications.  Tolerances  of  this 
magnitude  mean  nothing  unless  the  oscillator  in  which  the  crystal  is  to  operate  is  on  exact 
reproduction  of  the  oscillator  in  which  the  crystal  was  calibrated.  This  same  thing  applies  to 
wider  tolerances.  Persons  doing  work  where  close  tolerances  ore  required,  (Broadcast,  Com- 
mercial Two-Way,  Civil  Defense,  CAP,  etc.)  should  keep  this  in  mind.  The  FA-5  ond  FA-9 
Crystals  ore  guaranteed  to  be  calibroted  to  better  than  .01%  of  the  specified  frequency.  The 
average  FA-5  or  FA-9  Crystal  is  held  to  better  than  .005%.  This  tolerance  applies  only  when 
the  crystal  is  operated  into  32  mmf,  for  fundamental  crystals  and  anti-resonant  operation  for 
overtone  crystals.  The  information  shown  in  Table  I  is  of  value  in  setting  the  crystal  to 
frequency.  (Crystals  of  closer  tolerance,  and  for  special  circuits,  ore  available  from  our  com- 
mercial line.)

were  very  busy  watching  the  beautiful  girls,  also.  The 
boys  have  taken  over  the  49ers  Motel  at  Carson  City  each 
year  and  latest  reports  have  it  that  the  owners  of  said 
motel  intend  to  spend  the  winter  studying  the  code  and 
hope  to  have  W7  calls  next  year.  7ZT  held  his  usual  party 
for  the  gang  the  evening  of  the  parade.  Carson  City  cer- 
tainly gives  the  amateurs  a  roval  welcome  each  year.  W6 
calls  heard  in  \V7-Land  were  CTH,  EJY,  GCG,  ISO, 
PAZ,  U.I,  UUQ,  BMY,  YPM,  FNC,  LFZ,  GPU,  and  GGC. 
Svmday  morning  the  boys  had  their  usual  cIuId  breakfast 
before  setting  off  for  home  —  all  with  a  little  lighter  pocket- 
book.  The  2-meter  boys  on  c.d.  have  been  invited  to  join 
the  East  Bay  C.D.  Net,  2  meters.  ACN  recently  underwent 
an  operation.  Archie  worked  hard  to  get  the  license  plates 
for  the  \V6  boys.  Calls  were  heard  on  ]\ITN  for  blood  dona- 
tions and  many  responded.  Congratulations  to  PHT  on 
the  BPL  total.  SWP  didn't  get  liis  usual  high  score  in  as  his

emergency  so,  fellows,  let's  really  be  on  the  ball.  We  have 
lost  one  of  our  main  traffic  stations,  REF.  Betty  has  moved 
to  Wasliington  State.  Luck  to  you  at  your  new  location, 
Betty.  TYC  reports  that  he  is  getting  along  very  well  with 
the  PAM  appointment.  OPY  is  the  man  to  get  the  c.w.  nets 
on  their  way  and  I  believe  Harvej'  is  doing  everything 
possible.  Keep  up  the  good  work,  Harvey.  SUP,  K6GKR, 
and  KN6HLO  are  father,  mother,  and  son.  SBH  is  more 
than  filling  his  schedule  as  OBS.  New  officers  of  the  Tehama 
County  Amateur  Radio  Club  are  OEY,  pres. ;  SBH,  ^^ce- 
pres. ;  TMP,  secy.-treas.  This  is  a  very  fine  choice  and  the 
Club  sliould  go  far.  Tlie  new  SJVN  is  now  going  and  has 
several  members  in  this  section.  I  hear  that  this  net  is  to 
change  its  name  to  the  Central  Valley  Net.  We  are  sorry 
to  report  that  BHV  had  an  auto  accident  and  broke  his 
back.  6ANR  has  moved  to  Nevada  and  now  has  the  call 
7ANR.  Well,  fellows,  the  appointments  are  coming  along 
fine.  Let's  have  more.  Traffic:  W6MWR  20,  K6CFZ  15,

The  SJVN  is  active  again  on  3635  kc.  After  getting  poor 
results  on  CCN,  our  RM  decided  to  try  to  get  the  old  SJVN 
gang  active  again,  and  so  far  it  looks  hopeful.  Any  of  you 
who  are  interested  in  handling  some  traffic,  check  in  on 
3635  kc.  at  1900.  A  net  has  been  started  on  3900  kc.  at  1100 
Sun.  by  EBL  in  an  attempt  to  bolster  AREC  actjvity  and 
to  help  formulate  ideas  for  the  good  of  the  section.  It  is 
hoped  that  all  ECs  and  i  epresentatives  from  all  the  clubs 
in  the  section  will  check  in  regularly,  and  inform  the  rest  of 
the  section  of  the  loc„l  acti\aties.  This  also  should  help  to 
coordinate  activity  between  the  various  clubs.  TXM  is  the 
new  Kern  County  EC.  FKY  is  in  Detroit  for  a  \Tsit.  A  club 
is  beginning  to  take  shape  in  the  Sonora  Area.  This  will 
take  in  a  large  mountainous  area,  with  hams  widely  scat^ 
tered.  These  are  adverse  conditions  for  a  club,  but  the  gang 
is  determined  and  we  are  sure  it  wUl  be  a  success.  A  2-meter 
transmitter  hunt  held  by  the  Tu'-lock  Club  was  won 
by  SQR,  who  was  accompanied  by  GYN.  The  Stockton 
Club  visited  a  TV  station,  watched  a  studio  program,  and 
then  took  a  tour  of  the  entire  station.  K6DUU  and  W6ZRJ 
presented  very  interesting  and  informative  talks  to  the  Tur- 
lock  Club  on  incorporation  and  c.d.  K6BGM  is  NCS  on

Telrex  20-meter  beam.  The  Gastonia  C.D.  Net  meets  at 
7  o'clock  on  29,300  kc.  A  project  by  the  members  is  to  build 
portable  transmitters  and  receivers  with  batteries  for  fixed 
or  portable  operation.  The  Cliarlotte  C.D.  Net  meets  on 
3825  kc.  at  9  a.m.  Sun.  Plans  are  now  being  looked  over 
for  a  state-wide  emergency  organization  in  case  of  another 
"Hazel."  FUS  is  making  a  roster  of  stations  and  their 
hours  of  operation  during  the  hurricane.  If  your  station 
has  not  been  reported,  mail  information  to  FUS,  Maiden, 
N.  C.  The  call  letter  license  plate  bill  is  one  we  all  have  to 
work  on.  It  is  not  a  one-man  or  a  group  job.  I  have  lots  of 
information  from  the  Virginia  group  which  pushed  it  through 
in  that  State,  and  we  liave  lots  of  work  ahead  of  us.  CZR

This  is  a  double-conversion,  super-heterodyne  receiver  featur- 
ing a  high  signal  to  noise  ratio  and  sensitivity.  The  low 
frequency  second  I.F.  stages  provide  high  selectivity.  Minimum 
frequency  drift  for  phone  and  CW  operation  is  assured  by 
stabilization  of  the  variable  H.F.  Oscillator,  Fixed  H.F.  Oscil- 
lator and  the  B.F.O.  This  is  accomplished  by  the  use  of 
temperature  compensating  capacitors  and  voltage  regulation 
of   the   d.c.   supply   to   the    oscillators. 

The  circuits  employed  on  all  five  bands  consist  of  one  stage 
of  radio  frequency  amplification,  a  first  detector  and  high 
frequency  oscillator,  one  stage  of  IGOO  Kc.  intermediate  ampli- 
fication with  another  detector,  and  a  stabilized  high  frequency 
oscillator.  This  is  followed  by  two  stages  of  low  frequency 
intermediate  amplifiers  (260  Kc.)  followed  by  a  detector  of 
the  diode  type,  a  noise  limiter,  a  high  gain  audio  stage,  and 
the  audio  output  stage.  Automatic  volume  control,  beat  fre- 
quency oscillator,  voltage  regulator,  and  rectifier  circuits 
are   included. 

The  audio  output  stage  provides  a  full  five  watts  of  audio 
which  is  sometimes  needed  in  mobile  or  marine  installations 
having  high  ambient  noise  conditions.  The  unit  is  designed  to 
operate  from  either  115  V  GO  cycle  power,  G,  or  12  volts  d.c. 
An  illuminated  "S"  meter  and  rear  lighted  lucite  dial  assure 
ease    of   operation. 

A  socket  mounted  on  the  chassis  provides  a  mounting  place 
for  a  crystal  filter  or  a  crystal  calibrator  which  will  be  avail- 
able   as   accessories.  >. 

Rigid  steel  construction  affords  reliable  performance  under 
the  most  trying  conditions,  such  as  marine  and  mobile  instal- 
lations where  vibration  effects  become  very  serious.  This 
performance  packed  receiver  is  packaged  in  a  very  small 
case  measuring  only  123/8"  x  lOVj"  x  6V4"  overall. 
R-9  receivers  have  self-contained  115  V  GO  cycle  a.c.  power 
supplies.  For  mobile  or  marine  installations,  G  or  12  volt  d.c. 
vibrapacks  are  available.  No  modification  to  the  equipment  is 
necessary   for   operation   with   G   or    12   volt   d.c.    supplies.         '

New  Beam  Pentode 

This  new  transmitting  type  pentode  offers 
good  performance  even  at  low  plate  voltage 
.  .  .  and  requires  very  little  driving  power. 

For  example  ...  as  a  Class  C  amplifier 
it  will  deliver  output  of  60  watts  at  600 
volts  ...  74  watts  at  750  volts  ...  110 
watts  at  1000  volts  .  .  .  driving  power  is 
less  than  ^4  watt  in  each  case.  And  for 
higher-power  use,  output  of  250  watts  at 
2000  volts,  with  0.8  watts  drive! 

PL-6549  is  an  aligned-grid  pentode,  con- 
servatively' rated  at  75  watts  plate  dissipa- 
tion. Its  quick-heating,  6-volt  thoriated  tung- 
sten filament  ...  its  rugged  construction 
.  .  .  make  it  ideal  for  mobile  applications. 

The  suppressor  grid  of  the  PL-6549  gives 
it  excellent  current-division  characteristics 
.  .  .  thus  screen  power  requirements  are  very 
low.  It  offers  excellent  power  gain  and  out- 
put, either  as  an  audio  or  radio-frequency 
amplifier.  ^oi

"...I  have  found  the  Vest  Pocket  Beam  highly  sat- 
isfactory. Its  power  gain  appears  to  be  virtually 
equal  to  that  of  full  sized  beam  antennas.  I  think 
I  con  summarize  its  performance  by  saying  that 
when  I  call  stations  on  the  V— P  Beam,  they  come 
back !  Assembly  of  the  beam  was  a  straightforwar4 
simple  task  in  view  of  the  clear  instructions  and 
color  coding.  I  assure  you  1  am  well  pleased  with 
the  MOSLEY  Vest  Pocket  Beam  Antenna."

MOSLEY  'V-P'  Beams  are  made  as  small  as 
possible,  consistent  with  Ttug  Beam  Per- 
formance. Element  lengths  are  correctly  pro- 
portioned to  the  loading  coils  to  practically 
eliminate  end-fire»  Boom  lengths  and  element 
spacings  are  such  as  to  provide  outstanding 
forward  gain  and  front-to-back  ratio  with  neg- 
ligible SWR  over  a  convenient  bandwidth,

60  countries  in  4  months,  soys  Leo,  W4ERK,  Miami 

"...used  a  Vest  Pocket  Beam  on  20  about  four 
months.  Cannot  praise  it  too  highly.  We  worked 
all  48  states  in  7  weeks.  To  date,  over  60  foreign

very  satisfactory.  We  have  not  lost  a  single  con' 
tact  from  being  covered  up  with  QRM.  ...I  think 
this  beam  is  really  worthwhile."

"I  am  very  well  satisfied  with  my  Mosley  V— P 
Beam.  I  hear  countries  I  have  not  heard  with  any 
other  antenna  in  my  20  years  as  a  Ham." 

"Such  good  reports  hard  to  believe",  says  Frank, 
VE6AC,  Calgary,  Alberta,  Canada 

"...I  have  found  it  hard  to  believe  my  ears.  My 
power  input  ranges  from  22  to  50  watts  ...yet  my 
reports  are,  almost  without  exception,  much  better 
than  those  I  am  able  to  give.  My  Mosley  V— P

"Outstanding  results"  for  Whitey.    W4PQ,   Miami.

with  the  (Mosley)  40  Meter  Vest  Pocket  Beam. 
It  is  the  best  antenna,  possible,  for  a  city  lot.  It 
solved  all  my  problems.  I  have  been  getting  S— 9 
reports  from  New  Zealand  consistently.  I  have

For  amateur  operation  featuring 
Panoramic  reception  on  a 
3-inch  CR  Tube 

Why  operate  "blind"?  The  new  PANADAP- 
TOR  MODEL  PR- 1  provides  visual  monitoring 
over  a  band  of  frequencies  up  to  200  kc  lets 
you    "see"  .   .   .  everything    from    the    other 
fellow's  frequencies   in   three-way   or   round 
robin  QSO's  to  replies  to  your  CQ's.  You  see 
it  all  on  a  3-inch  CR  Tube  which  also  simplifies 
frequency  setting  and  station  monitoring,  facil- 
itates network  operations,   assists  in  making 
adjustments  of  transmitters  and  antennae,  en- 
ables    identification     and     interpretation     of 
transmitter   signal   characteristics   (your   own 
and  others),  selects  QRM-free  spots  for  sending 
and  listening. 

Once  you've  used  the  PR-1  on  your  rig — 
once  you've  gotten  the  "feel"  of  the  over-all 
band  picture,  seen  continuously — you'll  never 
again  want  to  feel  your  way  without  these  eyes!

in  our  224-page  1955  catalog.  Branch  Manager  WlWIS  —  sometimes  referred 
to  as  Mr.  Single  Sideband  —  and  staff  are  alert  to  the  needs  of  novice  and 
veteran  Hams  alike;  not  to  overlook  the  music  lovers,  servicemen,  experimenters 
•and  "do-it-yoyrself"  gentry  who  naturally  gravitate  to  Radio  Shack  because 
more  things  are  in  stock  at  the  right  time  .  .  .  and  because  our  prices  are 
capital-L-low.  In  other  words,  Radio  Shack  of  Connecticut  is  a  full-fledged

Auroral  Propagatioxi 

(Continued  from  page  16) 

visible  portion  of  such  formations,  but  one 
might  expect  that  a  good  returned  signal  could 
be  obtained  from  the  ends  of  the  arc  which 
appear  near  the  horizon.  The  rotary  Yagi  showed, 
however,  no  signals  coming  from  those  directions. 
This  is  another  case  of  no  signal  coming  from  the 
brightest  part  of  the  visible  aurora.  This  is  in 
agreement  with  Figs.  7  and  8,  showing  that 
signals  are  rarely  observed  in  the  east  or  the 
west,  but  only  in  the  northern  quadrant. 

V.h.f.  auroral  radar  echoes  have  been  studied 
at  several  other  places  in  the  northern  hemi- 
sphere, where  the  above-described  large  ranges 
and  restrictions  of  the  echoes  to  the  north  have 
also  been  found.  At  most  locations,  however, 
the  visible  aurora  has  occurred  predominantly 
at  large  distances  from  the  observing  site,  and 
so  the  radar  results  were  to  be  expected.  For 
example,  at  Ithaca,  New  York,  most  visible 
aurora  is  at  low  angles  in  the  north.  Overhead 
visible  aurora  is  seen  only  for  a  total  of  a  few 
hours  over  the  whole  year,  and  southern  aurora 
is  even  more  difficult  to  study.  For  high  latitudes, 
with  generous  quantities  of  aurora,  the  experi- 
mental observations  require  some  unusual  process 
to  be  involved  which  will  limit  the  echoes  to  the 
ranges  and  azimuths  that  are  found. 

An  Explanation 

Supported  by  these  observations,  Booker, 
Gartlein,  and  Nichols  ^^  at  Cornell  have  enlarged 
upon  a  theory  by  Moore  ^^  which  considers  the 
auroral  ionization  to  be  composed  of  numerous 
streaks  of  ionization  running  parallel  to,  or 
concurrent  with,  visible  auroral  rays.  Aurora  is 
believed  to  be  caused  by  charged  particles  shot 
from  the  sun  which  are  able  to  enter  the  earth's 
atmosphere  only  if  they  follow  the  lines  of  the 
earth's  magnetic  field.  Indeed,  auroral  rays  are 
sloped  slightly  with  respect  to  your  horizon, 
because  they  are  following  the  lines  of  the 
earth's  magnetism.  A  corona  (overhead  star- 
shaped  formation)  is  a  bundle  of  such  rays 
viewed  up  from  the  bottom,  the  center  appearing 
slightly  to  the  south.  Now  meteor  trail  ionization 
has  been  previously  studied  and  has  been  found 
to  give  v.h.f.  radio  reflections  best  when  looking 
perpendicular  to  the  trail.  ^^  The  perpendicular 
requirement  becomes  more  severe  as  one  uses 
higher  frequencies.  The  strength  of  the  reflected 
signal  fluctuates  during  formation  and  during 
wind  distortions  of  the  meteor  trail,  because  the 
contributions  to  the  total  signal  from  the  different 
parts  of  the  trail  interfere  with  each  other.^^

agines  the  auroral  ionization  to  be  composed 
of  hundreds  of  such  "meteor"  trails.  This  would 
explain  the  observed  fast-fading  or  growl  of  the 
aurorally-propagated  signal.  It  would  also  re- 
quire that  the  radio-ray  paths  be  nearly  perpen- 
dicular to  the  trails,  or  in  this  case,  the  earth's 
magnetic  field.  (See  Fig.  10.) 

Calculations  have  been  made  by  Chapman  '^ 
for  locating  the  feet  of  perpendicular  lines  from 
the  receiver  and  transmitter  to  the  lines  of  the 
earth's  magnetic  field.  These  calculations  relate 
the  height  above  the  earth,  the  range  of  e.\pected 
echoes,  the  angle  of  elevation  of  the  radio  path, 
and  the  latitude  of  the  echo  point  for  a  given 
magnetic  latitude  of  the  observing  site.  Theo- 
retically, auroral  echoes  should  be  limited  to 
northerly  directions  in  the  northern  hemisphere 
and  should  occur  only  at  large  distances  having 
low  angles  of  elevation.  This,  as  shown  in  earlier 
paragraphs,  is  verified  by  experiment. 

Since  auroral  reflections  can  come  only  from 
low  angles  of  elevation  with  respect  to  the  hori- 
zon, the  amateur  should  design  his  antenna  to 
favor  these  directions.  The  antenna  should  be 
very  sharp  in  the  vertical  plane  and  pointed  at 
the  horizon.  Thus,  vertical  stacking  is  highly 
recommended.  Low-angle  radiation  requires  that 
the  antenna  be  high  above  the  surrounding  ter- 
rain and  emphasizes  the  importance  of  a  good 
QTH  and  a  tall  tower.  The  perpendicularity 
theory  would  suggest  a  greater  spread  in  azimuth 
than  in  the  elevation  angle,  and  indeed,  simul- 
taneous echoes  have  been  obtained  from  sep- 
arated directions  in  the  north.  It  would,  therefore, 
be  wise  to  leave  the  horizontal  pattern  as  broad 
as  30  degrees  or  so,  meaning  that  the  antenna 
should  not  be  wider  than  about  4  dipoles.  Fre- 
quently, during  violent  aurora,  there  is  difficulty 
in  finding  the  direction  that  gives  maximum  sig- 
nal. It  is  tempting  to  think  that  such  behavior  is 
due  to  signals  arriving  from  high  angles  of  ele- 
vation, where  the  auroral  light  appears  brightest, 
l)ut  this  explanation  is  probably  false.  The  per- 
pendicularity theory  may  explain  why  aurora 
seen  visually  does  not  give  a  signal  because  of  its 
position.  (In  addition,  it  is  felt  by  some  that 
active  ray  forms  will  give  stronger  signal  than 
quiet  arc  forms.)  In  general,  sufficient  low-angle 
radiation  is  a  more  important  aid  in  getting 
strong  auroral  signals  than  was  previously  ex- 
pected. 

Acknovrledgeiaents 

A  large  vote  of  thanks  is  due  the  many  ama- 
teurs that  have  sent  in  auroral  reports  via  Tilton 
and  QST.  Here  is  a  further  example  of  amateur 
radio  supplying  research  information  difficult  to 
obtain  in  any  other  way.  Assistance  has  been 
rendered  by  Ken  Bowles,  W2MTU,  and  Ed  Til- 
ton,  WlIIDQ.  Financial  aid  has  been  provided 
by  the  U.  S.  Army  Signal  Corps  at  Cornell  and 
the  Geophysical  Institute  at  the  University  of 
Alaska.

Mobile  Converter 

(Continued  from  page  SO) 

The  r.f.  amplifier  may  now  be  lined  up,  band 
by  band,  by  tuning  in  a  signal  from  a  generator 
or  the  antenna,  and  then  adjusting  the  amplifier 
grid  and  plate  coils  for  maximum  response.  The 
grid-coil  slug  should  be  adjusted  with  signals 
near  the  high-frequency  end  of  the  band,  and 
with  Cs  set  near  minimum  capacitance.  The  an- 
tenna coupling  should  then  be  adjusted  to  the 
point  where  a  shght  peak  in  signal  or  background 
noise  is  heard  within  the  range  of  C3. 

At  3.5  and  7  Mc,  it  is  important  that  the  re- 
ceiver used  with  the  converter  be  well  shielded  if 
broadcast-band  interference  is  to  be  avoided. 
Most  car  receivers  are  well  shielded,  but  some  of 
the  less-expensive  communications  receivers  may 
not  be.  However,  the  converter  will  be  most  use- 
ful to  a  communications  receiver  at  the  higher 
frequencies  where  feed-through  will  usually  be 
negligible.  When  interference  from  local  broad- 
casting stations  is  experienced,  the  slug  of  Li 
should  be  adjusted  to  minimize  the  strongest 
b.c.  signal  toward  the  low-frequency  end  of  the 
b.c.  band,  while  the  slug  of  L2  should  be  likewise 
adjusted  for  the  strongest  signal  toward  the  high- 
frequency  end  of  the  band.  These  two  adjust- 
ments will  usually  serve  to  attenuate  most  other 
b.c.  signals  between  the  two  extremes  of  fre- 
quency. However,  other  combinations  may  be 
advisable,  depending  on  the  frequencies  of  the 
local  stations.  In  most  cases,  it  should  be  possible 
to  wash  out  b.c.  interference,  by  adjustment  of 
these  two  traps  to  the  point  where  it  is  no  longer 
bothersome. 

In  some  parts  of  the  country,  the  second  har- 
monic of  the  2900-kc.  crystal  will  beat  with 
WWV's  5-Mc.  signal,  so  that  it  will  be  heard 
when  the  b.c.  receiver  is  tuned  to  800  kc.  (or  sig- 
nal frequency  of  3700  kc).  This  can  be  used  as  a 
check  point  for  the  frequency  alignment  of  the 
b.c.  receiver. 

With  the  crystal  frequency  known,  ham-band 
frequencies  can  be  determined  quite  accurately 
(if  the  b.c  calibration  is  correct)  by  simply  adding 
the  h.f.-oscillator  frequency,  given  in  the  table, 
to  the  reading  of  the  b.c.  dial. 

Measurements  with  a  signal  generator  showed 
that  recognizable  audio  output  could  be  obtained 
with  a  signal  input  as  low  as  0.1  /xv.  Most  of  the 
background  noise  disappeared  with  the  input 
signal  raised  to  0.3  ^v.,  and  solid  reception  was 
possible  with  an  input  signal  of  about  0.5  fiv. 

The  cost  of  a  complete  set  of  components  for 
this  converter  will  run  about  $65.00.  The  crystal 
and  set  of  three  coils  required  for  each  band  runs 
about  $7.65,  so  that  the  cost  will  be  reduced  by 
this  amount  for  each  band  that  is  not  needed. 


TVI  and  BCI  we're  all  familiar  with,  but 
K2EPD  has  WPI.  Everytime  he  fires  up  the  rig, 
his  mother  complains  she  can  hear  him  in  the

loop  are  at  equal  distances  from  the  center.  A 
permanent  joint  can  then  be  made  between  an- 
tenna wire  and  pole  by  wrapping  several  turns  of 
bare  copper  wire  tightly  around  the  pole  where 
the  antenna  touches  it,  threading  the  ends  of  this 
bare  wire  through  small  holes  drilled  in  the  bam- 
boo pole,  and  then  soldering  together  as  shown  in 
Fig.  .3.  Use  a  good  grade  antenna  wire  so  it  will 
not  stretch  later. 

The  main  boom  consists  of  a  12-foot  piece  of 
2X2  pine  with  another  6-foot  piece  used  as  a 
center  brace  to  prevent  the  ends  of  the  boom 
from  dropping.  This  boom  is  mounted  at  its 
center  by  bolting  it  to  a  piece  of  angle  iron  welded 
to  the  top  of  the  rotator  shaft.  A  lower  boom 
composed  of  a  12- foot  piece  of  1  X  2  pine  is 
mounted  by  means  of  a  small  bracket  8  feet  43^ 
inches  down  the  rotator  shaft  parallel  to  and  in 
the  same  plane  as  the  main  boom.  The  completed 
radiator  and  reflector  are  fastened  to  the  ends  of 
the  main  boom  by  means  of  the  mounting  brack- 
ets, and  the  center  insulators  for  the  radiator  and 
reflector  are  fastened  to  the  ends  of  the  lower 
boom  which  also  serves  to  support  the  feed  line 
and  the  reflector  stub.  This  lower  boom  is  prob- 
ably unnecessary  but  it  does  make  the  beam 
neater  and  stronger. 

The  radiator  and  reflector  are  made  exactly 
the  same.  Small  insulators  are  placed  in  the  cen- 
ter of  the  bottom  side  of  both  reflector  and 
radiator  and  the  stub  is  fastened  to  the  one  and 
the  feed  line  to  the  other.  Seventy-two  ohm  coax 
will  give  a  very  close  match,  but  52-ohm  coax  has 
been  used  here  with  very  good  results,  even 
though  there  is  some  mismatch.  The  stub  for  the 
reflector  is  6  feet  long  and  spaced  3  inches.  A  very 
simple  sliding  short  can  be  made  by  putting  a 
Fahnestock  clip  on  each  wire  of  the  stub  and  then 
soldering  a  wire  between  these  clips.  This  "short" 
can  be  easily  slid  along  the  stub  from  the  top  of 
the  antenna  tower  or  pole  by  means  of  a  small 
stick.  Remember  to  use  bare  cooper  wire  for  the 
stub  or  the  sliding  short  will  not  work.  After  the 
beam  is  in  place  atop  the  tower,  the  reflector  may 
be  tuned  by  sliding  the  shorting  bar  up  and  down 
the  stub  until  a  minimum  S-meter  reading  is  ob- 
tained from  a  local  ham  located  off'  the  back  of  the 
beam.  That  is  all  there  is  to  it;  you  are  now  tuned 
on  the  nose  and  ready  for  business. 

Antenna  articles  always  seem  to  contain  a 
paragraph  or  two  telling  about  the  results 
achieved  with  the  antenna  under  consideration, 
usually  in  very  glowing  terms.  This  article  is  no 
exception.  This  beam  has  consistently  given  good 
results,  DX  reports  averaging  about  1  "S"  point 
higher  than  on  the  old  three-element  job,  and  if 
the  band  is  open  at  all  it  is  unusual  to  call  CQ  DX 
and  not  receive  at  least  one  reply.  The  power 
usually  runs  125  watts  here.  This  beam  is  not  a 
cure-all  for  your  DX  and  QTIM  problems,  but  it 
will  certainly  give  the  three-element  boys  a  good 
run  for  their  money.  Put  one  up  —  you'll  like  it.

Receiver  Performance 

(Continued  from  page  27) 

extremely  large  signal-handling  capabilities  re- 
quired. Several  tubes  recently  announced  show 
some  promise,  but  until  they  are  proven  the 
receiver  designers  laughingly  suggest  a  4-125A 
or  similar  for  the  receiver  r.f.  stage. 

To  prove  cross-modulation  when  operating 
"on  the  air,"  the  received  signal  can  be  reduced 
with  a  20-db.  resistive  attenuator.  This  will 
reduce  an  S9  signal  to  about  S6,  which  is  still 
readable,  but  at  the  same  time  drop  a  1-volt 
signal,  due  to  that  kilowatt  next  door,  to  0. 1  volt. 
If  the  splatter  disappears  when  the  atteimator  is 
placed  in  the  antenna  lead,  then  the  difficulty  is 
in  the  receiver.  Remember  not  all  modulation 
splatter  is  in  the  receiver.  A  few  inconsiderate 
amateurs  are  guiltj^  of  severe  overmodulation. 
A  more  simple  test  is  to  remove  the  normal  an- 
tenna and  connect  anj'  short  piece  of  wire  that 
will  reduce  the  desired  signal  to  a  just  readable 
level,  and  then  note  the  presence  or  absence  of 
splatter.  Either  test  is  acceptable  for  tracing  the 
source  of  this  type  of  interference. 

If  you  are  not  looking  for  weak  signals,  either 
of  the  above  methods  for  reducing  input  signal 
level  can  help  receiver  cross-modulation.  A  sepa- 
rate r.f.  gain  control  (variable  cathode  resistor) 
is  also  sometimes  helpful  in  reducing  the  cross- 
modulation  that  occurs  in  the  mixers. 

This  receiver  discussion  has  been  handled  in 
general  terms.  A  later  article  will  give  some  hints 
as  to  how  the  75A-3  can  be  adapted  best  to  serve 
the  amateur  with  special  interests  like  DX  work 
on  one  hand  or  just  local  rag-chewing  on  the 
other. 

I  would  like  to  express  my  appreciation  to  the 
many  Collins  engineers  who  assisted  in  this  dis- 
cussion of  receiver  performance. 

AppBiidix. 

So-called  thermal  noise  is  generated  in  any  resistance 
whether  it  is  the  antenna  resistance,  the  parallel  tuned 
impedance  of  the  r.f.  stage  grid  circuit,  or  an  actual  re- 
sistor. Noise  power  is  proportional  to  absolute  temperature, 
bandwidth,  and  resistance.  Noise  power  is  given  by 

N  =  —   = 

R  R 

where 

K  =  Boltzman's  constant  =  1.38  X  10-23; 

T  =  Absolute  temperature,  300°  at  room  temperature; 

A/  =  Bandwidth  in  cycles; 

Req  =  Noise  resistance  of  the  receiver  plus  the  dummy 

antenna;  and 

R  =  Sum   of   the   receiver   input   resistance   plus   the 

dummy  antenna  resistance. 


Signal  power  is  given  by  S  = 


(mgc)2 
R 


where  m  is  the  percentage  of  modulation  divided  by  100 
—  sometimes  called  modulation  factor; 

Ec  is  carrier  voltage  of  receiver  signal;  and  72  is  as  above. 
.\  perfect  receiver  is  one  wliich  has  no  noise  due  to  cou- 
pling circuit,  r.f.  stage  shot  noise,  mixer  noise,  or  any  other 
noise  contribution  except  that  of  thermal  noise  given  by  the 
above  expression.

For  the  past  35  years  radio  amateurs  throughout  the  world  have  been  purchasing  equipment 
and  supplies  from  me.  Their  friendship  and  loyalty  have  been  the  determining  factors  in 
our  success.  For  this  we  are  grateful  and  it  is  time  that  we  made  an  effort  to  express  our 
appreciation  in  a  material  way. 

Many  amateur  radio  clubs  need  financial  aid.  Many  others  can  use  extra  funds  if  these 
funds  can  be  obtained  without  assessing  their  members.  We  have  a  plan  which  will 
greatly  assist  all  amateur  radio  clubs. 

For  every  order  received  until  March  1,  1955,  we  will  send  our  check  for  15%  of  your 
order  -  to  your  radio  club  for  deposit  in  their  treasury.  When  you  place  your  order'be 
sure  to  include  the  name  and  address  of  your  club  and  treasurer. 

My  best  wishes  for  a  healthy,  happy  and  prosperous  New  Year.

As  the  actual  receiver  approaclies  theoretical  performance, 
the  above  expression  approaches  1.0,  or  0  db.  If  the  receiver 
noise  is  zero  except  for  thermal  noise  across  /?eq,  and  the 
antenna  matches  the  receiver  input  resistance,  then  fleq  = 
21?  and  the  noise  figure  is  2.0  (3  db.),  because  tlie  noise 
power  is  doubled  over  tliat  of  the  ideal  receiver. 

Example  1: 

.Assume  a  perfect  receiver  of  6-kc.  bandwidth  and  a  100- 
ohm  antenna  with  no  input  circuit  losses  or  set  noise.  What 
is  the  required  input  level  at  m  =  0.3  for  a  signal-phis-noise-

If  the  receiver  is  matched  to  the  antenna  (which  should 
be  done  in  the  practical  case),  then  the  noise  is  3  db.  greater 
and,  to  preserve  the  same  signal-to-noise  ratio,  the  signal 
must  increase  3  db. 

Ec  =  0.98  X  1.4  =  1.39  microvolts.

Suppose  the  receiver  of  Example  1  was  found  to  have  a

proper  adjustment.  With  the  'scope  connected  to 
the  r.f.  output  of  the  linear  the  loading,  bias  and 
excitation  should  be  adjusted  until  the  waveshape 
of  a  400-cycle  tone  is  a  replica  of  the  same  tone 
being  applied  to  the  driver.  When  modulation  is 
removed  the  amplifier  input  should  not  vary  and 
the  height  of  the  r.f.  envelope  on  the  'scope 
should  be  reduced  to  half  the  full-modulated  size. 
For  adjustment  with  single-sideband  exciters 
refer  to  the  1954  ARRL  Handbook. 

A  copper  plated,  expanded  steel  shield  was 
used  over  the  top  of  the  chassis  and  no  TVI 
complaints  have  been  filed. 

Don't  forget  that  every  point  in  this  circuit

ALL  ELECTRONIC  ENGINEERS 
WITH  A  DESIRE  TO 

CREATE  I 


The  building  of  a  ham  station  is  an  outlet  for  some  of  our 

creativeness.  In  the  35  years  I've  been  a  ham  operator,  I've 

found  a  lot  of  satisfaction  in  my  hobby:  but  nothing  gives  me  more 

creative  pleasure  than  my  job. 

At  the  Westinghouse  Electronics  Division,  creativeness  is 

encouraged.  Important,  too,  is  the  fact  that  the  work  is  so  vital! 

We're  working  on  advanced  development  projects  that  are  both 

interesting  and  challenging!  For  the  expansion  of  these  projects 

we  are  looking  for  electronic  engineers  experienced  in  radar  and 

Missile  Guidance  Systems. 

Of  course,  Westinghouse  offers  the  finest  income  and  benefit 

advantages,  as  well  as  a  good  location.  You'll  find  ideal  suburban 

living  accommodations  and  many  big-city  attractions. 

If  you'd  like  more  information  on  the  high-level  openings  to  be 

filled  in  the  near  future,  drop  us  a  line  today!

This  inexpensive 
product  will  do  the 
same  for  your  own 
rigs.  Follow  the 
lead  of  Johnson  and 
other  high  placed 
manufacturers. 


For  sealing  your  own  rigs  or  any  consumer, 
industrial  or  military  equipment  against  RF 
leakage  METEX  Electronic  Weatherstrip  is 
highly  effective  and  is  a  simple  operation. 
It's  made  of  highly  resilient  compressed  knit- 
ted wire  which  comes  in  several  forms  to  meet 
all  normal  requirements  even  where  closure 
is  of  an  uneven  nature.  Type  TVI  20-S  is 
easily  applied  to  most  rigs 
in  the  home  workshop. 
METEX  Electronic  Weath- 
erstrip is  the  simplest  and 
most  inexpensive  method 
for  sealing  in  RF  leakage 
yet  devised.  Try  it.  Results 
are  amazing.  Ham  and 
industrial  inquiries  invited.

Noise  Reduction 

{Continued  from  page  S7) 

really  big  advantage  of  the  traps  is  that  they 
do  not  interfere  with  motor  performance.  The 
decreased  motor  performance  will  bother  the 
amateur  who  loves  his  car,  as  he  does  his  ham 
rig.  Here  in  the  Cumberland  Mountains,  the 
loss  in  power  on  grades  when  suppressors  were 
used  was  distinctly  noticeable. 

The  traps  are  easily  constructed,  and  the 
mounting  problem  solved,  by  drilling  through 
standard  commercial  suppressors  to  open  their 
resistance  (not  strictly  necessary,  but  it  will 
increase  the  Q  of  the  circuit),  and  then  winding 
the  coils  around  them.  If  no  grid-dipper  is 
available,  7  turns  of  No.  20  wire,  close-wound, 
tuned  with  a  50-MAif.  disk  ceramic  condenser, 
will  be  effective  over  the  entire  ten-  and  eleven- 
meter  bands.  If  only  one-band  operation  is 
desired,  these  traps  are  well  worth  the  effort 
spent  in  constructing  them.  Similar  traps  should 
effectively  solve  your  noise  problems  in  circuits 
where  simple  by-passing  fails. 

In  case  anyone  is  worried  about  it,  removal  of 
the  suppressors  did  not  result  in  an  increase  in 
noise  on  the  b.c.  band.

c.w.  section  is  18,  and  contacts  made  on  the  same  band 
with  the  same  country  after  the  quota  is  filled  will  not 
count.  Thus  complete  exchanges  with  6  stations  in  one 
country  on  one  band  fill  the  band  quota  for  that  country. 
The  maximum  number  of  points  per  country  per  band 
which  may  be  earned  by  VE/VO  stations  in  the  c.w.  section 
is  24,  and  contacts  made  on  the  same  band  with  the  same 
country  after  the  quota  is  filled  will  not  count.  Exchanges 
with  8  stations  in  one  countrj'  on  one  band  are  thus  per- 
mitted Canadian  participants.  There  is  no  quota  for  stations 
in  the  c.w.  section  outside  of  the  U.  S.  and  Canada.  There  is 
no  quota  for  any  station  in  the  'phone  section. 

11)  Reporting:  Contest  work  must  be  reported  as  shown 
in  the  sample  form.  Each  entry  must  include  the  signed 
statement  as  shown  in  that  example.  Contest  reports  must 
be  mailed  no  later  than  April  29,  1955,  to  be  eligible  for 
QST  listing  and  awards.  All  DX  Contest  reports  become 
the  property  of  the  American  Radio  Relay  League.  No 
contest  reports  can  be  returned. 

12)  Awards:  To  document  the  performance  of  partici- 
pants in  the  Twenty-First  ARRL  International  DX  Com- 
petition, a  full  report  will  be  carried  in  QST.  In  addition, 
special  recognition  will  be  made  as  follows: 

a)  A  certificate  will  be  awarded  to  the  high  scoring  single- 
operator  'phone  and  to  the  high-scoring  single-operator  c.w. 
entrant  in  each  country  (as  shown  in  the  ARRL  Countries 
List)  and  in  each  of  the  73  U.  S.  and  Canadian  ARRL  sec- 
tions (see  page  6  of  this  issue)  from  which  valid  entries  are 
received.  In  addition,  a  certificate  will  be  awarded  to  the 
high  scoring  multiple-operator  station  in  each  section  or 
country  from  which  three  or  more  valid  multiple-operator 
entries  are  received. 

b)  A  suitable  certificate  will  be  awarded  to  the  operator 
making  the  highest  single-operator  'phone  score  in  each 
ARRL-affiliated  club,  provided  the  club  secretary  submits 
a  listing  of  a  minimum  of  three  'phone  entries  by  bona  fide 
resident  members  of  such  club,  and  provided  further  that 
these  scores  are  confirmed  by  receipt  at  ARRL  head- 
quarters of  the  individual  contest  logs  from  such  members. 
The  highest  single-operator  c.w.  scorer  in  each  club  will 
be  awarded  a  certificate  under  the  same  conditions. 

c)  ARRL  will  award  a  gavel  to  the  affiliated  club  sub- 
mitting the  greatest  aggregate  'phone  and  c.w.  score  by 
bona  fide  resident  club  members,  whether  single-  or  mul- 
tiple-operator entries,  provided  such  scores  are  confirmed 
by  receipt  at  ARRL  headquarters  of  the  individual  contest 
logs  from  such  members. 

13)  Judges:  All  entries  will  be  passed  upon  by  the  ARRL 
Award  Committee,  whose  decisions  will  be  final.  The  Com- 
mittee will  void  or  adjust  entries  as  its  interpretation  of 
these  rules  may  require. 

14)  Disqualifications:  Each  participant  agrees  to  observe 
the  contest  rules  as  well  as  all  regulations  established  for 
amateur  radio  in  his  country.  Some  examples  of  grounds 
for  disqualification  are:  off-frequency  operation  as  con- 
firmed by  a  single  FCC  citation  or  advisory  notice  or  two 
ARRL  accredited  Official  Observer  measurements;  low 
tone  reports  in  logs;  working  countries  on  the  "banned 
list  1"  —  footnote  information  applies  to  U.  S.  A.  amateurs 
only. 

'  As  we  go  to  press,  prefixes  to  be  avoided  are  FI8,  PK 
(except  PK7),  EP-EQ,  HL,  HS,  3W8  and  XW8. 


Patience,  practice  and  persistence  have  paid

simple  means  for  obtaining  a  c.w.  beat  note  witli  receivers 
like  the  522  and  Gonset  Communicator.  W6NOB  suggests 
a  b.f.o.  method  that  may  not  have  occurred  to  some  owners 
of  these  receivers.  He  has  a  Command  transmitter  hooked 
lip  near  his  Comiimnicator.  Turning  on  this  unit  and  tuning 
it  so  that  it  beats  with  the  Communicator  i.f.  does  the  trick 
very  nicely.  A  simple  crystal  oscillator  on  a  frequency  about 
1000  kc.  away  from  the  receiver  i.f.  will  also  do. 

Such  makeshifts  will  allow  you  to  copy  the  c.w.  sigs  you 
hear,  but  remember  that  they  will  not  give  you  a  full  appre- 
ciation of  the  value  of  c.w.  in  weak-signal  reception  until 
you  go  to  the  higher  selectivity  that  c.w.  makes  possible. 
Narrow  the  passband  down  to  a  few  hundred  cycles  and 
you'll  be  amazed  to  hear  the  way  the  readability  of  weak 
c.w.  shoots  up.  This,  however,  also  shows  that  the  tunable 
oscillators  in  these  receivers  are  rather  unstable.  The  next 
step  is,  of  course,  a  crystal-controlled  converter,  a  must 
for  any  real  2-meter  DX  enthusiast.

AN  ardent  amateur  radio  operator  is  the  commanding 
-^  officer  of  Naval  Reserve  Electronics  Division  8-12,  Paris, 
Texas,  which  won  the  Hooper  trophy  in  national  competi- 
tion for  excellence  in  Naval  Reserve  electronics  training. 
He  is  Cmdr.  Paul  H.  Daniels,  USNR,  W5CTM.  He  has 
held  an  active  amateur  license  for  30  years  and  a  com- 
mercial license  for  28  years. 

Cmdr.  Daniels'  interest  in  amateur  radio  activities 
helped  him  to  progress  rapidly  in  the  Naval  Reserve.  He 
enlisted  as  a  radioman  first 
class  in  1931.  Three  years 
later  he  was  chief  petty 
officer  in  charge  of  USNR 
Communication  Reserve 
Unit  No.  7,  .Junction  City, 
Kans.  At  that  time  he  was 
discharged  to  accept  a  com- 
mission as  ensign  in  the 
Naval  Reserve.  He  re- 
ported for  active  duty  to 
the  Commandant,  Norfolk 
Navy  Yard,  as  assistant 
communications  officer  in 
April,  1941. 

During  World  War  II 
Cmdr.  Daniels  served  on 
the  staff  of  Commander,  Operational  Training  Command, 
U.  S.  Atlantic  Fleet.  In  1947  he  was  designated  to  command 
Volunteer  Electronics  Warfare  Company  9-146,  Emporia, 
Kans.  He  was  relieved  of  command  when  he  moved  to 
Paris  in  1949.  Cmdr.  Daniels  was  assigned  to  Volunteer 
Electronics  Warfare  Company  8-51,  Paris,  as  training 
officer.  He  assumed  command  of  the  company  in  August, 
19.50.  On  deactivation  of  the  volunteer  company  in  1951 
and  activation  of  Organized  Electronics  Company  8-12, 
Cmdr.  Daniels  was  named  commanding  officer. 

He  has  made  his  hobby  his  profession.  In  civilian  life, 
he  is  chief  engineer  for  the  Paris  radio  station,  KPLT.

Six  members  of  Naval  Reserve  Electronics  Platoon 
8-50,  Clarksville,  Ark.,  hold  amateur  radio  licenses.  They 
are  Lt.  James  K.  Harrison,  W5WXN,  officer  in  charge; 
Russell  E.  Murray,  CWO,  W5VUL;  Phillip  B.  Latimer, 
ETC,  W5JPY;  Grover  F.  Krohn,  ATC,  W.5SXM;  Frank 
Carl  Eichenberger,  SA,  W5WUP;  and  Joseph  V.  Murray, 
SN,  WN5BGX.  W5WXN,  WN5BGX,  and  WoWUP 
obtained  their  General  Class  licenses  through  membership 
and  training  in  the  Clarksville  unit. 

Last  year  W5JPY  organized  a  code  class  for  members 
of  a  Boy  Scout  troop  to  qualify  them  for  a  code  merit  badge. 
Eight  scouts  continued  their  study  and  four  now  hold 
Novice  licenses.

Keep  up  the  good  work  ("  Fulminatin's  from  Ol'  Fogey," 
Nov.  QST).  To  me,  a  great  deal  of  the  pleasure  of  amateur 
radio  operating  is  gone  today  because  of  the  sloppy  tech- 
niques that  are  in  use  —  even  in  my  favorite  game  of  traffic 
handling.  .  .   .

East  Aurora,  N.  Y. 
Editor,  QST: 

I  just  got  my  Novice  about  two  months  ago,  and  am 
I  ever  having  fun! 

One  thing  which  is  very  noticeable  on  the  Novice  band 
is  the  time  spent  on  calling  CQ.  A  lot  of  the  Novices  call 
CQ  ten  times  or  more  before  giving  their  call.  I  feel  that  a 
CQ  consisting  of  CQ  three  times,  the  call  three  times,  and 
then  that  again  is  very  adequate.  Also,  after  making  a 
contact  with  a  station  it  is  only  necessary  to  give  his  call 
and  sign  yours  once,  or  at  the  most  twice.  I  am  quite  sure 
that  when  someone  calls  CQ  for  a  seemingly  endless  period 
of  time,  he  loses  contacts  because  a  lot  of  people  don't 
want  to  wait  until  the  call  letters  come  around. 

So,  Novices,  let's  make  our  CQs  a  little  shorter,  thus  our 
QSOs  a  little  more  interesting  and  numerous.

PI-NET  SAFEGUARD 

Chatham,  Mass. 
Editor,  QST: 

There  are  many  transmitter  circuits  in  QST  and  the 
Handbook  which  use  a  pi-network  output  circuit.  In  most 
of  these  circuits  danger  exists  in  case  of  failure  of  the  d.c. 
blocking  condenser.  This  can  place  the  d.c.  plate  voltage 
on  the  antenna  and  feeder.  In  commercial  designs  this 
possibility  is  anticipated  and  protection  provided  by  the 
use  of  an  r.f .  choke  between  the  output  terminal  and  ground. 
Examples  of  circuits  in  wliich  this  danger  could  exist  may 
be  found  in  Dec.  1953  QST,  p.  IS,  June  1954  QST,  p.  18, 
and  the  1952  Handbook,  pages  171,  156,  138. 

After  giving  a  httle  thought  to  this  situation  I  think 
you  will  agree  that  you  should  bring  this  point  to  the  atten- 
tion of  readers  of  your  publications. 

This  problem  is  not  based  on  theory  only.  I  know  of  an 
instance  where  a  serious  shock  resulted. 

—  William  C.  Ryder,  WIJNM 

[EoiTOR'a  Note  —  This  source  of  danger  has  been  recog- 
nized in  the  ARRL  Safely  Code  which  appeared  in  the  June, 
1952,  issue  of  QST.  This  measure  also  reduces  the  peak 
voltage  across  both  input  and  output  condensers,  since  it 
provides  a  d.c.  short  across  the  capacitors.  Since  the 
failure  of  the  blocking  condenser  may  cause  the  choke  to 
bum  out,  the  primary  of  the  plate  transformer  should  be 
fused,  not  only  as  a  measure  of  personal  safety,  but  also  to 
save  the  equipment.]

The  Military  Affiliate  Radio  System  has  en- 
tered upon  its  seventh  year  of  operation.  MARS 
will  continue  to  emphasize  the  training  of  ama- 
teur radio  operators  who  want  to  learn  more 
about  mihtary  radio  practices  and  procedures. 

Efforts  are  being  made  to  establish  an  effective

to  military  commanders  for  planned  use  in  the 
event  of  peacetime  disaster  or  national  emer- 
gency. 

The  Chief  Signal  Officer,  U.  S.  Army,  and  the 
Director  of  Communications,  U.  S.  Air  Force, 
sent  the  following  message  to  all  MARS  members 
on  the  anni  versary  date : 

SPECIAL  BROADCAST  — 26  NOVEMBER  1954 
To  All  MARS  Members 

The  Sixth  Anniversary  of  the  Military  Affiliate  Radio 
System,  26  November  1954,  marks  another  year  of  inte- 
grated radio  operation  and  training  between  Army  and  Air 
Force  communications  and  United  States  licensed  amateur 
radio  operators.  Events  of  the  past  year  have  proved  that 
military  unit  stations  at  Army  and  Air  Force  Bases  can 
be  netted  with  personally-owned  and  operated  amateur 
facilities  to  provide  a  reliable  system  for  training  and 
for  MARS  administrative  traffic.  Personal  messages  han- 
dled for  Armed  Forces  personnel  and  their  families  and 
friends  have  contributed  to  the  high  morale  of  our  service- 
men everywhere.  The  Chief  Signal  Officer  and  tlie  Director 
of  Communications  unite  in  extending  sincere  thanks  for 
your  loyalty  and  support.  We  urge  you  to  continue  to  carry 
on  the  advancement  of  MARS.  Sgd  Major  General  George 
I.  Back,  Chief  Signal  Officer,  United  States  .A.rmy,  and 
Major  General  Gordon  A.  Blake,  Director  of  Communica- 
tions, United  States  Air  Force.

Me^jU  FREED  COMPONENTS  /o^  HI-FIDELITY  AMPLIFIER 
PROVIDE   IMPROVED  PERFORMANCE 


This  Freed  circuit  incorporates  several  changes 
from  the  original  Williamson  circuit  to  provide  op- 
timum performance  at  high  and  low  frequency  ex- 
tremes. It  is  rated  at  10  watts  with  triode  connected 
output  tubes.  However,  by  connecting  the  screen 
grids  of  these  tubes  to  taps  provided  on  the  Freed 
KA-10  output  transformer,  it  is  possible  to  double 
the  power  output  for  a  given  distortion  percentage. 

Recommended  power  supply  is  choke-input  type 
with  a  two-section  L-C  filter  to  maintain  constant 
D.C.  output  and  to  improve  filtering  to  the  voltage 
amplifiers. 


Other  high  quality  Freed  components  Include  minia- 
ture audio  transformers,  magnetic  amplifiers,  toroidal 
inductors,  subminiature  encapsulated  pulse  trans- 
formers, precision  filters  and  a  complete  line  of 
precision  laboratory  test  instruments.  Complete  cata- 
logs are  available  to  engineers  requesting  same  on 
firm  letterheads. 


Freed  components  required 
for  this  amplifier  include:

Be^^  of  Your  Transmitter  to  Antenna  Match 
with  the  new  CoAx  Ratiometer  (swr.) 


Install  a  CoAx  Ratiometer  in  the  line  between  your  trans- 
mitter and  antenna  (or  tuner)  and  stop  guessing  at  a  proper 
match.  In  this  new  device,  well-established  principles  are 
applied  to  produce  a  unique  answer  to  the  problem  of 
measuring  standing  wave  ratios.  The  result  is  a  design  of 
exceptional  accuracy  and  simplicity. 

There  are  no  condensors  to  balance,  no  resistors  in  line 
to  dissipate  your  power.  The  unit  handles  frequencies  from 
2  to  200  MCS,  power  loads  from  10  to  1000  watts  (so  it 
can't  be  overloaded).  Rugged  construction,  but  so  compact 
it  can  easily  be  permanently  installed  inside  your  trans- 
mitter. Free  mounting  bracket  included  with  every  unit. 

Sensing  unit  may  be  purchased  with  or  without  the 
easy-to-read  remote  indicator.  Complete  instructions  include 
how  to  make  your  own  remote  indicator.  See  your  favorite 
distributor  today.  If  he  hasn't  heard  about  the  CoAx  Rati- 
ometer, send  us  his  name  and  your  check.  We'll  ship  direct 
to  you,  postpaid.  73-W8IJ

commercial In  nature,  and  Is  placed  and  signed  by  a 
member  of  the  American  Radio  Relay  League.  Thus, 
advertising  of  bona  fide  suri;lus  e<iuiiimcnt  owned,  used  au(l 
for  sale  by  an  individual  or  apparatus  offered  for  exchange  or 
advertising  inciuiring  for  special  equipment,  if  by  a  member 
of  tiie  American  Radio  Relay  League  take  the  7i  rate.  An 
attempt  to  deal  in  apparatus  in  quantity  for  profit,  even 
if  by  an  individual,  is  commercial  and  all  advertising  by 
him  takes  the  30C  rate.  Provisions  of  paragraphs  (1),  (2) 
and  (5),  apply  to  all  advertising  in  tliis  column  regardless 
of  which  rate  may  ai)ply. 

(7)  Because  error  Is  more  easily  avoided.  It  Is  re- 
quested signature  and  address  be  printed  plainly. 
Typewritten  copy  preferred. 

(8)  No  advertiser  may  use  more  than  100  words  in  any 
one  issue  nor  more  than  one  ad  in  one  issue.

A  good  microphone  can  improve  your  results 
as  much  as  a  high  gain  antenna 

Ever  notice  that  two  signals  of  the  same  "S  meter"  intensity  sound  dif- 
ferently? One  is  muddy,  dull,  a  little  hard  to  read — the  sibilant  letters 
like  S  and  F  almost  alike.  The  other  signal  is  sharp,  clean  and  readable 
even  in  QRM  and  QRN — because  there's  usable  intelligence.  No  mistake 
about  the  call  or  comments. 
The  greatest  variation  is  in  the  microphone.  A  sharp  peak  adds  no  intelligibility  but 
limits  the  modulation  to  that  value.  A  peak  of,  say  6  db,  which  is  usual  in  many 
ordinary  microphones,  will  reduce  voice  power  by  HALF.  Don't  be  fooled  by  a 
microphone  that  sounds  "louder" — loudness  by  itself  is  not  a  criterion  of  perform- 
ance; quite  the  contrary  since  it  may  indicate  undesirable  peaks. 

An  E-V  microphone  with  smooth,  peak-free  response,  replacing  an  inferior  instru- 
ment, often  will  do  more  for  a  phone  signal  than  a  new  antenna  or  increased  power. 
As  a  further  plus,  of  course,  you  get  well-known  E-V  durability,  style  and  perform- 
ance. An  E-V  microphone,  to  raise  stations,  to  carry  through  a  QSO,  is  your  best 
station  investment.  '

tive communications.  Amateur  discount  applies.

I^ITH  THE  RCA-652a 

A  new,  low-cost  twin  beam  power  Ivbe  lor  "ham"  use  in  the  420-450  Mc  band 

;"  J  if  you  are  planning  a  new  rig  for  fixed  or  mobile  operation  in 
the  420-450  Mc  range,  the  new  RCA-6524  is  the  tube  you 
want.  The  high  power  sensitivity  and  high  efficiency  of  the 
6524  permit  operation  with  moderate  plate  voltages  to  give 
large  power  output  with  small  driving  power.  In  cw  service, 
the  tube  will  take  45  watts  input  (ICAS)  at  470  Mc.  (See 
table  for  Ham-Band  ratings.) 

Design  features  of  the  6524  include  balanced  compact 
beam  power  units  which  have  low  interelectrode  capaci- 
tances, and  a  cathode  common  to  the  two  units  to  reduce 
cathode  inductance  to  a  minimum.  High-conductivity  seals 
and  short,  heavy,  internal  leads  minimize  rf  losses. 

The  6524  is  available  now.  Ask  your  local  RCA  Tube  Dis- 
tributor about  it.  For  technical  bulletin,  write  to  RCA,  Com- 
mercial Engineering,  Section  A37M,  Harrison,  New  Jersey.

All  G-E  Tubes  get  individual  tests 
to  assure  maximum  dependability! 


QUALITY-CONTROL  sampling  isn't 
enough  — though  G-E  standards 
for  this  lead  the  industry.  Every  Gen- 
eral Electric  tube  is  checked  for  im- 
portant operating  characteristics. 

Instrument  dials  say  if  the  tube  plate 
current  is  correct  ...  if  transconduct- 
ance  equals  the  prescribed  value  ...  if 
no  undesirable  reverse  current  flows 
in  the  grid  .  .  .  if  there  is  no  tube  short, 
open  circuit,  or  vacuum  leak. 

G-E  tubes  that  pass  these  individual 
tests,  must  run  the  gauntlet  of  quality- 
control  checks  for  over-all  satisfactory 
performance.  Are  microphonics  at  a 
minimum.-*  Does  life-testing  leave  tube 
characteristics  unchanged.'  Only  if  the 


answers  to  these  and  many  other  ques- 
tions are  "yes"  can  G-E  tubes  be  car- 
toned and  shipped. 

The  tubes  your  G-E  tube  distributor 
sells  are  the  best  that  precision  manu- 
facture, rigid  inspection,  and  thorough 
testing  can  produce.  Install  them  with 
confidence!  General  Electric  Co.,  Tube 
Department,  Schenectady  5,  New  York. 


General  Electric  congratulates  the  winner  of  the 
1954  Edison  Award,  Benjamin  S.  Hamilton,  W6VFT, 
La  Mesa,  California.  The  judges  named  Mr.  Hamil- 
ton as  the  amateur  whose  achievement  was  most 
noteworthy,  because  he  provided  San  Diego  County, 
California,  with  "an  outstanding  Civil  Defense  and 
disaster-emergency  radio  network".  Recognition 
given  to  Award-winner  W6VFT  and  to  others  whom 
the  judges  cited,  was  equally  a  tribute  to  the  public- 
spirited  efforts  of  radio  amateurs  everywhere.

covering  ratings  from  25  to  500  watts. 

One  of  the  first  things  you  will  notice  about  the 
Series  "K"'  control  is  its  smoothly  operating  sliding 
contact,  mounted  snugly  in  its  unique,  spring- 
loaded  and  hinged  carrier. 

The  firm  direction  of  force  exerted  by  this  assem- 
bly eliminates  completely  the  problem  of  "rocking"" 
contacts  which  has  jtlagued  power  control  users  for 
years.  The  specially  compounded  copper-graphite 
contact  lubricates  the  resistance  element,  at  the 
same  time  that  it  reduces  the  contact  resistance 
between  the  two  parts.  A  flexible  pigtail  connection 
provides  a  direct  electrical  path  between  the  contact 
and  the  center  collector  mechanism. 

Perhaps  the  most  outstanding  feature  of  this  whole 
assembly,  however,  is  its  construction  which  allows 
the  contact  to  be  lifted  from  the  resistance  element 
for  cleaning  purposes  without  distorting  or  dis- 
turbing the  applied  force.  Incidentally,  the  contact 
is  almost  as  easy  to  replace  as  the  brushes  in  a 
small  ele<tric  motor. 

The  spring  coiiertor  and  shaft  assembly  is  spring- 


loaded  to  assure  virtually  constant  electrical  con- 
ductivity for  the  life  of  the  control.  In  addition,  all 
Series  "K"  controls  above  25  watts  are  equipped 
with  a  copper-graphite  buffer  plate  as  a  part  of  the 
collector  assembly  to  reduce  erosion  as  well  as 
assure  positive  electrical  contact.  The  shaft  is 
centered  and  insulated  from  the  electrical  circuit 
by  means  of  a  high  quality  steatite  bushing. 

The  body  of  each  Series  "K"  cbntrol  is  formed 
from  electrical  grade  porcelain  and  each  turn  of  the 
resistance  winding  is  uniformly  wound  on  this 
form  to  provide  an  even  progression  of  resistance 
change  vs.  shaft  rotation.  A  non-alkaline,  non- 
hygroscopic  enamel  is  applied  carefully  to  the 
winding,  and  then  heated  to  a  hard,  glass-like 
finish  for  maximum  protection  to  the  vulnerable 
parts  of  the  winding. 

The  smaller  sizes,  25  through  150  watt,  are  equipped 
with  conventional  threaded  bushings  for  panel 
mounting;  sizes  above  150  watt  are  equipped  with 
set  screws.  All  sizes  have  panel  locating  lugs  which 
may  be  adjusted  for  universal  mounting.  Suitable 
knob  and  dial  plate  are  supplied  with  each. 

A  brochure  containing  dimensional  drawings  of 
these  controls,  plus  catalog  listings,  has  been  pre- 
pared. For  your  copy,  write  to  us  at  Box  1558, 
Indianapolis  6,  Indiana.  Meanwhile,  check  with 
your  Mallory  Distributor,  and  take  a  good  look  at 
these  power  controls.  Their  construction  alone  will 
inspire  confidence  in  their  ability  to  operate  prop- 
erly for  a  long,  long  time.

the  new  LOW  COST 

PR  crystal 
especially  made  for 
converters,  experimental 
applications,  etc. 

Increased  demand  for  broad  tolerance 
crystals  (frequencies  outside  amateur 
bands)  has  resulted  in  the  new,  low-cost 
Type  2XP  .  .  .  especially  created  for  con- 
verters, some  types  of  receivers,  experi- 
mental applications  and  other  special 
uses.  Now  you  can  buy  top  PR  quality 
crystals  in  Type  2XP  for  these  special  re- 
quirements at  practically  the  same  cost  as 
regular  amateur  frequencies.  ASK  YOUR 
JOBBER  FOR  THE  NEW  2XPs.  Of  course, 
if  close  tolerance  is  required,  we  recom- 
mend PR  Type  Z-1,  our  regular  commercial 
crystal  .  .  .  but  these  will  cost  more,  nat- 
urally. You  will  find  that  the  inexpensive 
Type  2XP  will  fill  most  of  your  require- 
ments, at  a  big  saving!

^«^  AMERICAN 
RADIO  RELAY 
LEAGUE,  INC., 

is  a  noncommercial  association  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
advancement  of  the  radio  art  and  of  the  public  welfare,  for  the 
representation  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  incorporated  association  without  capital  stock,  chartered 
under  the  laws  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu- 
facture, sale  or  rental  of  radio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amateur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited.  A  bono  fide 
interest  in  amateur  radio  is  the  only  essential  qualification;  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  granted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the,  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us..." 


FCC'S  20th  anniversary 

The  Federal  Communications  Commission 
last  year  marked  its  20th  anniversary  of  exist- 
ence as  the  federal  agency  regulating  all  forms 
of  radio  and  wire  communication. 

Old-timers  will  recall  that  most  radio  matters 
were  administered  by  the  Department  of  Com- 
merce prior  to  1927 ;  the  Radio  Act  of  that  year 
created  a  Federal  Radio  Commission,  with 
duties  obvious  from  its  name.  Our  affairs  were 
handled  by  FRC  until  the  Communications 
Act  of  1934  designated  a  Federal  Communica- 
tions Commission  to  take  over  radio  regulation 
from  FRC,  and  to  have  in  addition  responsi- 
bility for  wii-e  telephone  and  telegraph  matters. 
The  1934  change  had  no  particular  effect  on 
amateurs  oi-  on  radio  in  general,  for  it  was 
simply  administiation  by  substantially  the 
same  Commission  and  staff  as  FRC.  The  anni- 
versary seems  an  appropriate  one  to  look 
back  to  our  regulatory  status  two  decades  ago. 

The  new  Commission  inherited  from  FRC 
(in  reality,  from  itself!)  a  fairly  sound  set  of 
amateur  regulations  —  they  having  been  com- 
pletely revised,  in  consultation  with  the 
League,  a  year  earlier.  It  was  also  an  extremely 
simple  text;  that  the  one  printed  page  of 
regulations  existing  sUghtly  more  than  20 
years  ago  has  grown  to  more  than  10  pages  of 
fine  print  today  is  a  measure  of  the  increasing 
complexity  of  even  the  amateur  phase  of  the 
art. 

In  June,  1934,  there  were  46,390  amateur 
radio  operators;  today  there  are  approximately 
125,000.  In  those  days  licenses  were  issued  in 
Classes  C,  B  or  A  for  three-year  terms,  a 
relatively  new  set-up  from  the  earUer  one-year 
licenses  of  the  generallj^-comparable  Tempo- 
rary, First  Class,  and  Extra  First  Class  tickets. 
(Comparable,  that  is,  except  for  the  Tempo- 
rary^ certificate,  which  like  our  pi'esent  Novice 
license  had  a  one-j'ear  nonrenewable  term.) 
There  were  32  quarterly  examination  points, 
compared  with  (31  at  present  (plus  thousands 
more  volunteer  amateur  examiners  under  our 
current  procedures.) 

The  code  speed  was  10  w.p.m.  and  you  had 
to  copy  the  text  in  longhand  — •  no  printing. 
One  3^ear's  experience  was  required  before 
taking  the  Class  A  test,  which  license  entitled 


you  to  the  delights  of  voice  operation  in  3900- 
4000  (that's  as  big  as  the  'phone  band  was) 
and  14,150-14,250  kc.  A  commercial  'phone 
license  waived  the  technical  e.xam.  Flunking 
any  exam  made  you  wait  90  days  before  tack- 
ling it  again  —  it's  now  30  days.  The  power 
limit,  as  always,  was  a  kw.  If  you  used  any  of 
the  bands  below  14.4  Mc.  you  had  to  put  a 
filter  on  your  i)ower  supply,  but  raw  a.c.  was 
permissible  above  that  point.  It  is  worthy  of 
note  that  we  had  "gone  d.c."  for  even  the 
lower  bands  only  a  few  years  earlier.  You 
could  operate  mobile  only  above  56  Mc.  (mean- 
ing, in  effect,  the  56-60  Mc.  band),  and  only 
in  aircraft  —  there  was  no  mobile  operation 
as  we  know  it  todaj'.  The  license  automatically 
granted  jjortable  privileges  in  any  band,  but 
this  was  also  a  brand  new  regulation;  only  a 
3'ear  earlier  separate  portable  licenses  and  calls 
were  required  for  such  operation. 
The  bands  were: 

1715-2000  ke. 

3500-4000  kc. 

7000-7300  kc. 
14,000-14,400  kc. 
28.000-30,000  kc. 
56,000-60,000  kc. 

You  could  also  operate  anywhere  above  110 
Mc;  no  one  else  was  using  those  "micro- 
waves" in  1934.  But  it  w\as  pretty  tough  to 
generate  any  r.f.  with  gear  then  available; 
even  to  get  to  56  Mc.  a  lot  of  hams  were  remov- 
ing "lossy"  bases  from  tubes. 

For  'phone  operation  any  amateur  could  use: 

1800-2000  kc. 
28,000-28,500  kc.  r 

56,000-60,000  kc. 

with  the  Class  A  boys  additionally  entitled 
to  75-  and  20-meter  voice.  You  could  transmit 
music  if  3'ou  were  engaged  in  bona  fide  tests 
of  modulation  gear. 

In  the  interests  of  strict  accuracy,  we 
should  point  out  that  amateurs  were  assigned 
one  additional  band:  400,000-401,000  kc. 
To  our  knowledge  no  amateur  ever  had  a  QSO 
there.  As  the  story  goes,  the  band  was  ear- 
marked for  us,  j^ears  and  years  ahead  of  any 
possible  practical  use  of  that  territory,  because 
that  frequency  was  calculated  .  (erroneously,  as 
it  turned  out)  as  one  for  which  the  parabolic 


reflector  of  the  common  electric  heater  could 
be  used  for  beam  purposes. 

It  should  be  noted  that  the  few  differences 
between  the  over-all  band  limits  above  and 
those  we  have  today  are  largely  a  result  of 
international  regulatory  agreements  and  not 
arbitrary  rulings  bj^  the  Commission;  FCC 
has  always  assigned  amateurs  in  this  country 
practically  every  kilocycle  permitted  under 
international  treaty.  In  the  formation  of  the 
U.  S.  viewpoint  toward  international  regula- 
tion the  Commission  has  been  an  unqualihed 
supporter  of  the  amateur,  as  of  course  ha\-e 
most  other  Government  agencies  concerned. 
In  this  field  during  the  last  twenty  years  we 
recall  particularly  the  1936  FCC  hearings, 
looking  toward  the  Cairo  world  conference  of 
1938,  and  the  1944  hearings,  looking  toward 
the  Atlantic  City  conference  of  1947,  at  both 
of  which  —  as  in  every  conference  since  1927 
—  amateur  radio  was  practically  on  trial  for 
its  life.  We  know,  with  pardonable  pride,  that 
the  testimony  put  into  the  records  on  behalf  of 
amateur  radio  established  pretty  thoroughly 
our  right  to  continued  use  of  our  frequencies 
because  of  our  record  of  operation  in  the  public 
interest,  convenience  and  necessity.  Yet  many 
of  the  contributions  of  amateur  radio  are  in- 
tangibles, and  it  is  indeed  a  rare  group  of  men 
who  are  possessed  of  sufficient  wisdom  and 
vision  to  w^eigh  these  against  the  hard  and  cold 
facts  and  statistics  of  the  commercial  users, 
and  come  up  with  the  answer  they  have. 

The  progress  that  amateur  radio  has  made 
these  past  twenty  years  could  never  have  been 
made  without  the  help  and  cooperation  of  a 
Federal  agency,  representing  the  established 
Government  viewpoint  toward  encouragement 
of  scientific  endeavors  on  the  part  of  its 
citizens  as  an  advancement  of  the  national 
interest  and  culture.  To  the  Commission  as 
an  agency,  the  League  extends  its  sincere 
appreciation.  Equally  as  important,  to  the 
many  individuals  on  the  staff  who  have  over 
these  years  worked  in  our  interest,  the  League 
on  behalf  of  all  amateurs  extends  its  warm 
thanks. 


OUR  COVER 


Nowadays  accurate  frequency  checking  is  an 
important  responsibility  of  every  amateur.  The 
secondary  frequency  standard  shown  on  this 
month's  cover  is  designed  for  just  that  purpose, 
as  well  as  being  compact  and  economical.  It  is 
capable  of  supplying  50-kc.  check  points  through- 
out the  communications  spectrum.  In  addition, 
it  can  be  used  with  high-frequency  crystals  for 
identification  of  the  points.  The  unit  is  described 
in  detail  starting  on  page  14  of  this  issue  in 
"Frequency  Marker  with  50-Kc.  Intervals."

QST  for 


A  Compact  Dual  Beam  for  20  and 
40  Meters 

Two-Band  Operation  with  Simplicity 
BY  L.  J.  JENSEN.*  W0MIQ 


•  W0MIQ  has  built  a  simple  compact 
dual  rotatable  beam  for  20  and  40  meters. 
After  preliminary  adjustments,  bands 
can  be  changed  instantly  at  the  flip  of  a 
switch.  The  system  is  fed  with  a  single 
coax  transmission  line  with  low  s.w.r.  on 
both  bands.  The  boom  is  only  15  feet 
long,  and  the  elements  24  feet,  so  it  will 
fit  in  almost  any  backyard. 


THE  recent  revival  of  loaded  antennas  has  not 
only  made  it  possible  for  the  ham  with  a 
small  backyard  to  put  up  a  rotatable  arraj^ 
for  20  meters,  but  it  has  also  made  a  40-meter 
parasitic  beam  mechanically  feasible  for  the  aver- 
age ham.  A  logical  development  of  this  principle 
is  the  use  of  a  single  set  of  elements  for  two-band 
operation,  simply  shorting  out  loading  coils,  or 
portions  of  them,  for  the  highcr-frequencj^  band. 
Element  spacing  is  not  a  problem  because  a 
spacing  of  approximately  0.1  wavelength  at  40 
meters,  where  maximum  gain  occurs  with  the 
parasitic  element  tuned  as  a  director,  becomes 
0.2  wavelength  spacing  at  20  meters.  This  spacing 
is  close  to  optimum  if  the  parasitic  element  is 
adjusted  as  a  reflector.  The  loading  coils  can  be 
shorted  out  by  means  of  relays. 

The  photographs  and  sketches  show  the  con- 
struction of  a  two-element  beam  covering  20  and 
40  meters.  The  boom  is  15  feet  long,  and  the 
elements  are  24  feet  long.  The  array  is  easil}^ 
turned  with  a  TR-4  TV  rotator.

This  view  shows  the  assembly  at  the 
driven-element  end  of  the  boom.  Ex- 
cept for  the  Hnk  winding  and  coax- 
cable  connection  to  it,  the  assembly  at 
the  parasitic  end  of  the  boom  is  identi- 
cal. Shielded  relay  control  wires  also 
are  run  through  the  boom,  emerging 
through  a  hole  in  the  boom,  and  enter- 
ing the  relay  box  at  the  rear.  Vertical 
guys  are  attached  to  the  insulators  at 
the  ring-bolt  in  the  end  of  the  boom, 
and  horizontal  guys  to  the  inner  ends 
of  the  upper-element  conductor.  The 
metal  base  and  angles  between  the 
boom  and  redwood  support  help  to 
stiffen  the  mechanical  joint.  The 
enter  braid  of  the  coax  cable  is  con- 
nected to  the  boom.  Weather-proof 
tape  is  used  to  seal  the  coax  cable  and 
reduce  corrosion  at  electrical  joints. 


elements  are  close-spaced,  results  in  a  high-Q 
circuit  in  which  the  reactance  will  vary  rapidly 
with  a  change  in  frequency.  Thus  any  matching 
adjustment  will  hold  over  only  a  relatively  small 
portion  of  the  band.  This  can  be  alleviated  to  a 
considerable  degree  by  using  a  pair  of  conductors 
for  each  element,  and  fanning  them,  as  shown  in 
the  photographs.  This,  in  effect,  increases  the 
size  of  the  conductor.  The  curves  of  Fig.  1,  made 
with  a  Millen  s.w.r.  bridge,  show  that  with  a 
match  at  the  center  of  the  7-Mc.  band,  the 
s.w.r.  does  not  e.xceed  1.75  to  1  at  the  ends  of  the 
band.  At  14  Mc,  there  is  the  added  benefit  of 
wide  spacing.  These  curves  were  made  with  a 
single  matching  adjustment  for  both  bands. 

The  transmission  line  (52-ohm  coax)  is  in- 
ductively coupled  to  the  center  loading  coil. 
On  20  meters,  the  radiator  element  is  shortened 
only  sufficiently  to  permit  the  use  of  enough 
loading-coil  inductance  to  provide  adequate 
coupling  to  the  link.  Loading  inductance  is  added 
to  make  the  electrical  length  of  the  elements 
suitable  for  7-Mc.  operation.  A  pair  of  relays 
shorts  out  the  40-meter  loading  coils  in  each  ele- 
ment when  operating  on  20  meters. 

Construction 

The  boom  is  a  15-foot  section  of  3-inch  diame- 
ter ST-61  aluminum  tubing  with  J/fg-inch  wall. 
A  guy  wire,  connecting  the  ends  of  the  boom, 
runs  over  a  truss  at  the  center  of  the  boom  to 
add  rigidity.  The  boom  is  fastened  at  its  center 
to  a  mounting,  shown  in  one  of  the  photographs, 
by  means  of  two  large  U  bolts.  This  mounting 
permits  the  boom  to  be  tilted  in  either  direction 
for  adjustment  of  the  loading  coils  merely  by  re- 


March  1955 


The  elements  of  this  dual 
20  -  40-nieter  beam  are  only 
24  feet  over  all,  and  the  boom 
is  16  feet  long.  The  elements 
are  fanned  for  broadbanding. 


moviiifi  (jne   of    the   hinge    bolts   or   the   other. 

Similar  U  bolts  at  each  end  of  the  boom  support 
a  mounting  for  the  antenna  elements.  These 
mountings  are  of  redwood,  l^g  inches  thick,  3% 
inches  wide  and  7  feet  long. 

Each  half  element  is  made  up  of  two  12-foot 
lengths  of  ST-61  aluminum  tubing,  jo  inch  in 
diameter  with  Jig-inch  walls.  At  each  of  the 
inner  ends,  the  tubing  is  flattened  and  drilled 
for  the  threaded  rod  of  a  feed-through  insulator. 
At  the  outer  ends  of  the  supports,  the  elements 
are  attached  to  similar  feed-through  insulators 
by  means  of  clamps  fashioned  from  sheet  metal. 
The  threaded  rod  of  the  outer  feed-through 
insulator  is  made  to  e.xtend  about  6  inches  above 
the  top  of  the  insulator.  This  extension  serves 
as  a  vertical  truss  in  bracing  the  elements.  Also 
attached  to  this  insulator  with  a  sheet-metal 
strap  is  a  30-inch  length  of  ^-inch  aluminum 
tubing  that  will  serve  as  a  horizontal  truss.  The 
ends  are  guyed  to  the  vertical  truss  at  the  feed- 
through  insulator. 

The  two  conductors  of  each  element  are  fanned 
out  at  the  ends  so  that  their  tips  are  separated  30 
inches.  The  spreaders  are  made  of  the  same  ma- 
terial as  the  elements,  and  are  flattened  at  the 


ends  and  drilled  for  screws  that  fasten  them  to 
the  elements.  The  tips  of  the  elements  are  simi- 
larly flattened  and  drilled,  but  the  elements  are 
not  flattened  for  the  short  intermediate  spreaders, 
since  this  would  weaken  the  elements.  The  short 
spreaders  are  placed  as  shown  in  the  photograph. 

A  system  of  gu.y  wires  is  used  to  brace  the  ele- 
ments both  vertically  to  prevent  drooj)ing,  and 
horizontally  to  reduce  whip.  Copper-clad  stranded 
steel  guy  wire  used  in  TV  work  is  good  material 
for  these  guys.  The  guy  wires  are  insulated  from 
the  boom,  but  not  from  the  elements.  On  each 
side  of  the  boom,  a  guy  wire  runs  from  a  strain 
insulator  fastened  to  the  boom,  over  the  truss  at 
the  outer  feed-through  insulator,  and  thence  to 
the  upper  bolt  at  the  short  spreader. 

The  horizontal  guj'S  run  from  the  stand-off 
insulators  at  the  inner  ends  of  the  elements  to  the 
horizontal  truss,  and  thence  to  a  bridle  at  the 
short  spreader.  This  bridle  is  simply  a  piece  of 
guy  wire  loosely  spanning  the  spreader. 

The  relays  that  short  out  the  40-meter  loading 
coils  are  enclosed  in  standard  3  X  4  X  5-inch 
aluminum  bo.xes.  The  relays  should  be  of  the 
antenna-changeover  type  with  good  insulation 
and   heavy-current   contacts,    such  as   the  Ad- 


Each  element  is  guyed  both  vertically  and  horizontally.  The  vertical  truss  is  a  brass  rod  extending  above  the 
outer  feed-through  insulator.  The  horizontal  truss  is  a  piece  of  aluminum  tubing  attached  to  the  same  insulator  with 
a  clamp.  Similar  clamps  anchor  the  clement  conductors  to  the  insulator.

28-volt  models  at  $1.29  each,^  operating  them 
from  a  100-ma.  selenium-rectifier  supply. 

Leads  to  the  loading  coils  are  larought  out 
through  1-inch  ceramic  feed-through  insulators 
set  in  the  sides  of  the  boxes.  These  feed-through 
insulators  also  serve  as  mountings  for  all  coils  ex- 
cept the  link  coil.  The  latter  is  fastened  to  a  piece 
of  34-inch  polystj'rene  sheet  attached  to  the  red- 
wood support  for  the  elements.  The  mounting 
screws  also  serve  as  terminals  for  connecting  the 
coax  line  to  the  link.  The  coax  line  is  fed  through 
the  boom  to  a  point  near  the  center  where  it  leaves 
through  a  hole  to  an  anchorage  on  the  mast.

Fig.  1  —  Curves  showing  s.w.r.  measured  on  trans- 
mission line  feeding  the  dual  heani. 

The  loading  coils  shown  are  wound  with  heavy- 
duty  aluminum  clothesline,  although  3  8-i"ch  to 
^Ye-inch  copper  tubing,  or  No.  8  copper  wire 
could  be  used.  The  20-meter  loading  coil  in  the 
driven  element  has  8  turns  13  2  inches  in  diameter, 
turns  spaced  approximately  the  diameter  of  the 
conductor.  The  link  coil  has  5  turns,  similarly 
spaced,  2  inches  in  diameter.  The  40-meter  load- 
ing coils  in  the  driven  element  each  have  20  turns 
13-2  inches  in  diameter.  In  the  parasitic  element, 
the  20-meter  coil  has  11  turns,  and  the  40  meter 
coils  18  turns  each,  all  13^2  inches  in  diameter. 

After  completion,  the  entire  beam  was  sprayed 
with  two  coats  of  acrylic  or  plastic  lacquer.  All  ex- 
posed electrical  connections  were  first  covered 
with  plastic  tape  and  then  sprayed. 

Adjustment 

The  parasitic  element  should  be  adjusted  as  a 
reflector  for  20- meter  operation  first,  with  the 
40- meter  loading  coils  shorted  out  and  the  driven 
element  open  at  the  center.  In  my  case,  it  was 
made  5  per  cent  electrically  longer  than  a  half 
wave  for  14.2  Mc.  With  a  grip-dip  meter  cou- 
pled to  the  20-meter  loading  coil,  the  resonant 
frequency  should  be  adjusted  to  13.5  Mc.  bj^ 
squeezing  or  spreading  the  turns  as  necessary. 
If  this  does  not  suffice,  it  may  be  necessary  to 
add  or  subtract  a  turn.  Then,  with  the  shorts  re- 
moved from  the  40-meter  loading  coils,  the  coils 
should  be  adjusted  for  element  resonance  at  7.5

Mc.  This  gives  an  electrical  length  about  4  per 
cent  shorter  than  a  half  wavelength  —  a  proper 
length  for  operation  as  a  director. 

Attention  should  now  be  turned  to  the  driven 
element.  With  the  40-meter  loading  coils  shorted 
out,  the  output  terminals  of  a  52-ohm  s.w.r. 
bridge  should  be  connected  to  the  link  terminals, 
and  a  suitable  r.f.  source  fed  to  the  bridge.  Fol- 
lowing recommended  procedure,-  the  20-meter 
loading  coil  should  be  adjusted  for  minimum 
s.w.r.  Then,  with  the  shorts  removed  from  the 
40-meter  loading  coils,  these  coils  should  be  ad- 
justed similarly. 

The  52-ohm  coax  line  may  then  be  connected 
and  a  recheck  of  the  match  made  by  connecting 
the  bridge  to  the  transmitter  end  of  the  line.  Ad- 
justment should  be  made  as  close  to  the  final 
elevation  as  possible.  If  the  adjustment  as  checked 
with  the  s.w.r.  bridge  at  the  input  of  the  line  does 
not  hold  after  the  array  has  been  put  in  place, 
the  s.w.r.  measurements  will  show  the  frequency 
of  minimum  s.w.r.,  and  thus  the  direction  in 
which  the  driven  element  should  be  retuned. 

If  greater  f.-b.  ratio  is  desired,  the  procedure  will 
be  the  same,  but  it  should  start  out  with  a  greater 
electrical  length  (lower  resonant  frequency)  for 
the  reflector,  and  a  shorter  electrical  length 
(higher  resonant  frequency)  for  the  director. 

In  conclusion,  I  want  to  thank  W0PUB  whose 
ever-ready  strong  arm  enabled  countless  experi- 
ments to  be  completed  with  success.

Frequency  Marker  with  50-Kc.  Intervals 

A  Compact,  Low-Cost  Unit  Using  Surplus  Crystals 

BY  BEVERLY  DUDLEY  * 


•  Here  is  a  frequency  staiiiiurd  huilt 
around  the  low-freqiieiiey  F'r-2HA  crys- 
tals, and  using  a  niultivihrator  to  oittain 
markers  every  50  kc.  t hrcjupliout  the 
eoniniunication  spe<'lruni.  The  oscil- 
lator circuit  is  one  thai  Mill  work  Mith 
high-frequency  crystals  as  well,  and  thus 
provide  spot  checks  for  identifying  the 
oO-kc.  harmonics. 


A  FREQUENCY  MARKER  providing  spot  frequen- 
cies at  intervals  of  50  kc.  per  second  is  a 
'-  useful  piece  of  measuring  equipment  for  the 
radio  amateur,  not  alone  because  it  permits  ac- 
curate determination  of  the  amateur  band  limits, 
but  because  it  provides  means  for  calibrating 
receivers,  variable-frequency  oscillators  and  simi- 
lar gear.  The  frequency  marker  described  in  this 
article  provides  crystal-controlled  marker  fre- 
quencies at  50-kc.  intervals  up  to  at  least  30  Mc. 


Power  to  operate  the  unit  is  taken  from  the 
60-cycle  line.  The  frequency  marker  contains  its 
own  power  supply,  consisting  of  a  6.3-volt  1-am- 
pere  filament  transformer,  and  a  half-wave 
selenium  rectifier  and  resistance-capacitance 
smoothing  filter  comprised  of  Ci.  d,  and  Ri. 
Protection  against  short  circuits  to  ground  is 
provided  by  the  ground  coupling  capacitor,  C12, 
in  the  output  circuit. 

The  crystal  oscillator  uses  a  6AK5  pentode  in 
an  electron-coupled  Pierce  oscillator  circuit,  with 
the  screen  of  the  pentode  serving  as  the  plate  of 
an  equivalent  triode  while  output  to  the  multi- 
vibrator is  taken  from  the  plate  of  the  pentode. 
The  frequency  of  oscillation  can  be  adjusted  over 
a  small  range  by  means  of  the  variable  capacitors 
Cs  and  d.  Capacitor  d  is  used  to  raise  the  fre- 
quency, whereas  C3  lowers  the  frequency  slightly. 
Both  of  these  capacitors  are  mounted  on  a  single 
ceramic  base  as  a  double  trimmer,  and  each  has 
a  capacitance  range  of  from  10  to  170  /x^f-  A 
series   capacitor,    C5,    was   used   to   reduce   the

Except  for  the  115-volt  a.c.  source  of  power,  it  is

3  by  4  by  5  inches  in  size.  It  uses  a  low-frequency 
crystal,  such  as  are  now  readily  available  on  the 
surplus  market  in  FT-241  or  FT-243  holders  for 
two  dollars  or  less. 

Circuit 

As  the  wiring  diagram.  Fig.  1,  shows,  the 
marker  comprises  a  OAKS  crystal-controlled 
oscillator,  followed  by  a  ()U8  triode-pentode 
frequency-controlled  multivil)rator  adjusted  to 
provide  marker  frequencies  at  intervals  of  50  kc.

Output  from  the  plate  of  the  6AK5  is  fed  to  the 
grid  of  the  triode  section  of  the  6U8  multivibrator. 
The  frequency  divider  consists  of  an  electron- 
coupled  multivibrator.  When  free  running  (i.e., 
not  controlled  by  the  crystal  oscillator)  its  fre- 
quency^ range  extends  from  about  30  to  80  kc, 
depending  upon  the  setting  of  the  frequency- 
adjusting  resistor,  R(,.  When  the  multivibrator  is 
frequency  controlled  to  operate  at  51)  kc,  R(,  has  a 
value  of  about  23,000  ohms.  Aside  from  the  fea- 
ture of  electron  coujiling,  which  virtually  elim- 
inates effect  of  load  on  operation  of  the  fre- 
quency marker,  the  only  unusual  feature  of  the 
multivibrator  circuit  is  the  use  of  series  resistors 
in  the  grid  circuits.  These  tin;  not  necessary  but

are  used  as  an  aid  in  producing  a  reasonably  good 
square-wave  output  at  50  kc. 

Adjustment 

The  oscillator  goes  into  oscillation  easily  when 
the  crystal  is  plugged  into  its  holder.  The  multi- 
vibrator is,  perhaps,  easiest  adjusted  by  coupling 
its  output  to  a  communications-tjpe  receiver 
and  varying  the  resistance  of  Rr,  until 
marker  frequencies  are  produced  at  in- 
tervals of  50  kc.  This  adjustment  is 
most  easily  done  in  the  broadcast  band, 
or  a  similar  low-frequency  band  of  a 
multiband  receiver.  Proper  adjustment 
is  that  for  which  the  note  in  the  receiver 
is  sharp  and  clean.  It  will  probably  be 
found  that  the  desired  condition  of 
operation  can  be  obtained  with  Rf,  ad- 
justable throughout  a  small  range  of 
angular  rotation.  If  adjustment  is  made 
b}'  means  of  a  receiver  alone,  the  mid- 
point of  this  angular  rotation  is  prob- 
ably the  best  adjustment,  but  a  check 
at  the  high-frequency  end  of  the  receiver 
is  advisable. 

If  a  cathode-ray  oscilloscope  is  avail- 
able, it  can  be  used  to  permit  the  output 
to  be  adjusted  more  nearly  to  a  square 
wave.  This  is  done  by  connecting  the

scope. The  oscilloscope  sweep  circuit  should  be 
adjusted  to  provide  horizontal  sweep  of  from 
10  to  50  kc,  and  the  synchronizing  adjustment 
should  be  advanced  to  lock  the  trace  into  a  sta- 
tionary pattern  showing  several  cycles  of  wave- 
form of  the  multivibrator.  The  resistor  Rg  may 
then  be  adjusted  to  that  value  of  resistance 
which  yields  the  most  nearh-  square  wave  on 
the  screen  of  the  oscilloscope. 

Operating  Data 

Power  consumption  is  small  (approximately 
10  watts)  and  thus  the  unit  may  be  left  running 
continuously.  Very  little  drift  —  only  a  few 
cycles  per  second  —  is  observed  in  warming  up, 
however,  so  for  most  frequency  measurements  it 
is  not  really  necessarj'  to  leave  the  unit  running. 
The  crystal  frequency  can  be  adjusted  to  e.xact 
value  by  varying  C'3  or  C'4  until  the  output  is  in 
zero  beat  with  signals  received  from  WWV. 

A  score  of  crystals  have  been  used  with  this 
frequency  marker  and  in  all  cases  oscillation  oc- 
curred readily.  The  multivibrator  has  synchro- 
nized easily  with  crystals  whose  fundamental 
frequencies  were  200,  400,  and  500  kc.  The  oscil- 
lator also  worked  well  with  cr\'stals  having  fre- 
quencies of  10(M)  and  5000  kc,  but  the  multi- 
vibrator would  not  SN-nchronize  at  all  with  the 
5-Mc.  crystal,  and  only  with  difficulty  and  not 
too  satisfactorily  with  the  1-Mc.  crystal.  This  is  in 
accordance  with  usual  good  practice  of  not  using 
multivibrators  for  dividing  the  frequency  of  the

Overtone  Crystals  — How  and 
Where  To  Use  Them 

Some  Circuits  and  Their  Adaptation  to  V.  H.  F.  Gear 

BY  EDWARD  P.  TILTON,  WIHDQ 


THOUGH  we've  used  overtone  crj-stal  oscil- 
lator circuits  in  v.h.f.  work  for  quite  a  few 
years,  it's  a  safe  bet  that  the  vast  majority 
of  all  hams  who  employ  overtone  techniques  have 
little  understanding  of  what  actually  goes  on  in 
such  oscillators.  Several  types  of  overtone  crj'stal 
circuits  were  discussed  in  detail  in  QST  some 
years  back/  and  this  information  appears  in 
boiled-down  form  in  all  recent  editions  of  the 
Handbook.  It  is  suggested  that  the  reader  go  over 
these  references,  as  what  is  to  follow  is  supple- 
mentary to  them. 

All  overtone  oscillator  circuits  have  one  basic 
feature  in  common:  some  method  of  introducing 
additional  feed-back,  beyond  that  normally 
present  in  simple  oscillator  circuits.  The  differ- 
ence between  the  various  overtone  circuits  lies 
mainly  in  the  method  of  controlling  the  feed- 
liack.  The  idea  is  to  give  the  crystal  a  little  extra 
regenerative  kick,  on  the  frequency  of  the  desired 
overtone,  to  encourage  oscillation  at  that  fre- 
quency rather  than  on  the  fundamental.  There 
should  be  only  just  enough  to  accomplish  this, 
without  causing  the  stage  to  take  off  on  a  fre- 
quency determined  by  the  tuned  circuits,  rather 
than  by  the  crystal.

•  The  economy  and  circuit  simplicity 
that  are  achieved  through  the  use  of 
overtone  crystal  oscillators  have  a  price: 
the  need  for  some  care  on  the  part  of  the 
user,  to  be  sure  that  they  are  adjusted 
and  operated  properly.  Overtone  crystals 
and  circuits  should  he  thought  of  as 
tools  useful  in  attaining  certain  ends, 
rather  than  as  an  all-inclusive  technique 
to  replace  other  methods  in  v.h.f.  circuit 
design.  Here  the  good  and  bad  features 
of  overtone  circuitry  are  sorted  out,  to 
enable  the  v.h.f.  man  to  decide  whether 
they  are  right  for  the  job  at  hand. 


oscillate  is  determined  by  the  waj'  it  is  cut  from 
the  main  crystal,  and  in  the  case  of  frequencies 
we're  interested  in  here,  by  its  thickness.  The 
crystal.  Fig.  lA,  is  deformed  mechanically  during 
oscillation,  as  shown  in  greatly  exaggerated  form 
in  Figs.  IB  and  IC.  When  the  crystal  oscillates  on 
an  overtone  (the  fundamental  frequency  divided 
by  some  odd  number)  it  breaks  down  into  sep- 
arate layers.  There  are  three  layers  for  a  3rd- 
overtone  oscillation,  five  for  5th,  and  so  on.  The 
overtone  crystal  looks  like  Fig.  ID  and  IE,  again 
greatly  exaggerated.  There  is  no  fundamental- 
frequency  oscillation  at  this  time,  nor  is  it  possi- 
ble to  develop  oscillation  on  even  multiples.

QST  for 


When  we  remember  that  a  crystal  is  actually  a 
very  thin  plate,  we  can  see  why  some  work  per- 
fectly on  their  design  frequencies,  but  refuse  to 
oscillate  on  overtones.  And  it  is  obvious  why 
extreme  care  must  be  taken  in  grinding  and 
mounting  crystals  where  overtones  higher  than 
the  third  are  to  be  used.  A  7-Mc.  BT-cut  crystal 
is  only  about  0.014  inch  thick.  This  means  that 
the  overtone  layers,  even  for  3rd-mode  operation, 
are  less  than  0.005  inch  in  thickness.  For  5th 
mode  they  are  less  than  0.003  and  for  7th,  0.002 
inch  thick!  This  doesn't  allow  much  for  varia- 
tions in  thickness  due  to  imperfect  grinding. 
Even  a  tiny  scratch  on  the  surface  may  destroy 
overtone-mode  operation  entirely.  The  slight  con- 
vex curvature  usually  imparted  to  the  surfaces 
of  standard  crystals  also  may  prevent  high-order 
overtone  oscillation. 

The  method  of  mounting,  too,  may  have  con- 
siderable bearing  on  how  well  the  crystal  will 
work  in  overtone  service.  Pressure  mounting,  as 
in  the  FT-243  type  of  holder  so  commonly  used, 
clamps  the  crystal  in  place  and  tends  to  inhibit 
overtone  oscillation.  In  general,  crystals  mounted 
in  the  small  CR-7  type  of  holder,  with  electrodes 
in  the  form  of  plated  areas  on  the  crystal  surfaces, 
tend  to  work  better  on  overtones  than  do  pres- 
sure-mounted types.  The  capacitance  of  the 
holder  may  be  an  important  factor  in  the  attain- 
ment of  high-order  overtones,  and  here,  again, 
the  CR-7  holder  and  mounting  method  are 
superior. 

Just  about  any  crystal  that  will  work  well  on 
its  intended  frequency  will  oscillate  reasonably 
well  on  its  3rd  overtone.  Higher  overtones  are 
generally  unsatisfactory  with  crystals  ground  for 
fundamental  use.  The  5th  may  be  found,  but 
with  a  majority  of  run-of-the-market  crystals  it 
will  be  low  in  output  and  very  critical  in  adjust- 
ment. This  applies  to  crystals  between  5  and  12 
Mc.  Lower  than  5  Mc,  the  crystals  are  thick 
enough  so  that  5th  and  sometimes  higher  over- 
tones can  be  developed.  Fifth-mode  operation  of 
3.5-Mc.  crystals,  for  instance,  may  be  quite 
satisfactory.  We  keep  hearing  about  this  or  that 
pet  circuit  that  makes  possible  the  development 
of  high-order  overtones  with  any  cr^-stal,  but 
many  hours  of  tedious  adjustments  with  any 
number  of  circuit  variations  and  with  hundreds 
of  crystals  have  convinced  the  writer  that  trying 
for  overtones  beyond  the  3rd  with  crystals  higher 
than  about  5  Mc.  is  a  waste  of  time  and  patience, 
unless  crystals  ground  especially  for  overtone 
service  are  used. 

Overtone  Circuitry 

With  crystals  ground  and  mounted  for  over- 
tone use,  even  simple  circuits  will  work  satis- 
factorily, provided  that  there  is  a  tuned  circuit  at 
the  overtone  frequency,  as  in  Fig.  2A.  This  is 
suitable  for  use  between  12  and  54  Mc,  the  range 
over  which  relatively  ine.xpensive  3rd-mode  crys- 
tals are  currently  available.  There  is  some  over- 
lap between  12  and  20  Mc.  as  to  whether  a  crystal 
is  an  overtone  type  or  not.  Most  manufacturers 
supply  overtone  crystals  for  any  frequency  above 


12    Mc,    though   fundamental  crystals   can   be 
made  up  to  about  20  Mc. 

The  simplest  circuit,  Fig.  2A,  ordinarily  does 
not  provide  enough  feed-back  to  make  funda- 
mental crystals  in  the  6-  to  9-Mc.  range  take  off 
on  the  3rd  overtone,  however,  so  some  provision

Flexibility  in  the  Antenna  Coupler 

A  Wide-Range  Antenna  Tuner  and  Coax-Matching  Circuit 

BY  T.  H.  PUCKETT,*  W5JXM 


•  Antenna  couplers  don't  seem  to  have 
chanfjed  much  over  the  years,  but 
matchinfi  the  coupler  to  a  coax  line  is 
becoming  increasingly  important  to 
amateurs.  Here  is  a  unit  which  performs 
both  functions  in  one  package. 


THE  advent  of  low-pass  filters  and  pi-tank 
output  circuits  has  just  about  made  some 
form  of  transmission-line  impedance  match- 
ing a  must  in  amateur  stations.  Also,  if  a  balanced 
antenna  and  transmission  line  is  used,  most 
amateui's    these    days    prefer    to    put    in    some 


anced  to  single-ended  convcision,  and  an  adjust- 
able L-C  section  for  matching  to  the  coax 
transmission  line. 

The  complete  circuit  is  given  in  Fig.  1.  Barker 
and  Williamson  type  TA  plug-in  coils  are  used 
for  7'i,  the  balanced-to-single-ended  converter. 
These  are  designed  for  this  purpose,  being  made 
of  tinned  wire  so  that  taps  may  be  easily  made. 
Two  clips  are  furnished  with  each  coil  for  making 
taps. 

The  antenna  side  of  the  circuit  is  a  more  or 
less  conventional  plug-and-jack  arrangement 
which  may  be  connected  for  either  series  or  paral- 
lel feed.  Fig.  2A  shows  the  plug  arrangement  for 
parallel  feed,  and  B  for  series  feed.  The  taps  on

because  of  its  greater  convenience  in  installation. 
This  antenna  coupler  is  designed  to  perform 
both  of  these  functions  in  one  package,  and  to 
have  enough  range  to  accommodate  any  of  the 
usual  amateur  antenna-feedline  combinations. 
This  is  achieved  by  using  plug-in  coils  for  bal-

the  coil  are  not  needed  for  series  feed,  but  are 
indicated  because  the  same  coil  might  be  used  for 
both  series  and  parallel  feed  at  different  times. 
Dummy  jacks  are  provided  for  storing  the  taps. 

The  antenna  tuning  capacitors  Ci  and  Co 
have  a  maximum  capacitance  of  250  nnt  each, 
which  is  considerably  more  than  is  necessary 
to  resonate  the  80-meter  coil.  However,  it 
is  sometimes  convenient  to  have  the  extra 
capacitance  available,  as  some  antennas  couple 
considerable  reactance  into  the  tuner  which 
must  be  canceled  out  to  achieve  resonance. 
As  it  was  expected  to  use  this  coupler  only  on 
the  80-,  40-  and  20-meter  bands,  no  great 
thought  was  given  to  the  rather  large  minimum 
capacitance  of  these  capacitors.  If  regular 
15-  or  10-meter  operation  is  planned  it  is  sug- 
gested that  150-  or  even  100-/u/if.  capacitors  be 
substituted.  Also,  it  would  probably  be  wise  to 
make  the  circuit  a  little  more  symmetrical.  As 
may  be  seen  in  the  back  view,  one  capacitor  is 
much  nearer  the  variable  inductor  than  the  other, 
and  has  an  aluminum  support  bracket  fastened 
to  it. 

The  coax  line  side  of  the  unit  may  be  set  to 
three  different  configurations  by  the  circuit 
switch  Si.  These  are  shown  in  Fig.  3.  A  shows

Low-Noise  Receiver  Design 

Reworking  a  Receiver  for  Maximum  Sensitivity 
BY  HARRY  LONGERICH,*  W2GQY/4,  AND  ROBERT  D.  SMITH,**  W5LHD 


•  This  is  an  interesting  article  telling 
how  two  amateurs  were  able  to  improve 
considerably  the  performance  of  a  com- 
mercial receiver.  We  think  you  will  be 
interested  in  the  reasoning  and  the  cir- 
cuitry involved.  However,  it  should  be 
pointed  out  that  the  improvement  that 
can  be  expected  with  any  receiver  will 
be  in  proportion  to  the  poorness  of  its 
present  performance  and  the  lack  of 
outside  noise  at  one's  location  —  you 
can't  expect  these  changes  to  help  a 
currently-good  receiver  or  one  in  a  noisy 
location. 


AFTER  spending  several  hundred  dollars  for  a 
/%  new  receiver,  most  of  us  feel  rather  pleased 
-^  ■■-  with  ourselves  —  if  we  didn't,  that  hollow 
sensation  in  the  hip  pocket  would  be  hard  to 
bear.  But  how  about  a  few  months  later,  when 
the  noveltj'  has  worn  off  and  we've  settled  down 
to  some  serious  DX  operating?  Are  there  ever 
any  little  gnawing  doubts?  Probably  more  often 
than  most  of  us  would  care  to  admit.  The  crux  of 
the  situation  is  that  while  one  receiver  may  have 
better  selectivity,   stability,   or  operating  con-

a  low-noise  mixer  is  used,  one  good  r.f.  stage  should  he

venience  than  another,  they  are  pretty  much 
alike  so  far  as  front-end  performance  is  con- 
cerned. This  is  because  the  industry  long  ago 
settled  on  pentode  r.f.  amplifiers  and  pentagrid 
mixers  as  the  accepted  standard.  Obviously,  two 
r.f.  stages  are  better  than  one  or  none,  but  manu- 
facturer X's  r.f.  amplifiers  or  mixers  will  have 
essentially  the  same  noise  figure  as  those  of 
manufacturer  Y.^ 

.\s  it  turns  out,  low-noise  amplifiers  have 
been  easiest  to  build  for  the  v.h.f.  bands  because 
of  the  small  frequency  coverage  (percentagewise) 
demanded  of  most  v.h.f.  receivers.  External  noise 
is  lowest  in  the  v.h.f.  bands,  and  hence  full  ad- 
vantage can  be  taken  of  low-noise  r.f.  amplifiers. 
General!}'  accepted  theory  considers  that  ex- 
ternal noise  (static,  etc.)  is  so  strong  below  25 
Mc.  that  it  is  useless  to  use  special  circuits  to 
reduce  internal  receiver  noise  on  our  general 
operating  frequencies.  While  this  is  essentially 
true,  we  believe  the  critical  frequency  to  be 
more  in  the  order  of  10  Mc,  indicating  low- 
noise  circuits  for  three  of  our  most  important 
DX  bands.  This  figure  of  10  Mc.  is  somewhat 
variable,  depending  on  local  conditions;  certainly

Testing  Your  Receiver 

Here  is  a  simple  test  to  determine  whether  or 
not  a  lower  noise  figure  would  help  j'our  own 
receiver:  set  it  to  or  near  your  favorite  DX  band 
(use  your  regular  receiving  antenna),  tune  in  a 
frequency  entirely  free  of  any  signal,  advance  the

gtiiii  until  the  noise  is  at  a  comfortable  level,  and 
now  substitute  a  resistor  having  the  same  value 
as  the  antenna  input  impedance,  usually  about 
300  ohms.  If  there  was  not  an  appreciable  de- 
crease in  noise  when  the  antenna  was  replaced  by 
the  resistor,  your  receiver  can  stand  improve- 
ment: most  of  the  noi.se  remaining  is  being  gen- 
erated within  the  receiver. 

We  made  the  above  test  on  a  modified  HRO-5, 
and  found  that  internal  set  noise  masked  much  of 
the  weak-signal  DX.  In  the  course  of  testing  this 
and  other  receivers,  another  interesting  fact 
came  to  light.  Literature  covering  weak-signal 
reception,  available  to  us,  generally  states  that 
the  first  r.f.  stage  is  the  most  important  since  its 
noise  is  amplified  more  than  that  of  any  other 
stage.  This  apparently  does  not  hold  true  for  the 
average  amateur  receiver;  a  considerable  amount 
of  noise  is  contributed  by  the  pentagrid  mi.xer 
or  converter  stage.  Further  research  into  the 
subject  disclosed  that  pentagrid  mi.xer  and  con- 
verter tubes  available  today  have  an  equivalent 
noise  resistance  ranging  from  62,000  to  300,000 
ohms; "  in  addition,  conversion  transconductance 
is  low.  Economic  factors  and  construction  con- 
venience have  generally  dictated  the  use  of 
conventional  mixers  or  converters,  because  they 
are  simple  and  inexpensive  and  perform  fairly 
satisfactorily  for  most  medium  frequency  ap- 
plications.   However,    at   frequencies   above    10 

2  RadiotTon  Designer's  Handbook,  4th  Edition,  page  938. 

3  The  more  elements  there  are  in  a  vacuum  tube,  the 
greater  the  noise  tliat  is  produced,  because  of  the  random 
division  of  the  cathode  current  between  the  elements.  See 
Terman,  Radio  Engineer's  Handbook,  page  294. 


Mc,  they  may  leave  quite  a  bit  to  be  desired. 

R.  F.  Amplifiers 

The  triode  is  the  least  noisy  vacuum  tube 
amplifier  known.  A  check  of  tubes  narrowed  our 
choice  to  a  triode-connected  6AC7,  or  the  minia- 
ture version,  the  6AH6,  since  they  have  the 
highest  Qm  and  therefore  the  lowest  equivalent 
noise  resistance  of  available  triodes.' 

A  straight  triode  amplifier  is  not  practical 
because  it  will  oscillate  without  neutralization, 
and  neutraUzation  is  impractical  in  multiband 
receivers.  The  grounded-grid  ampUfier  overcomes 
this  objection,  but  in  turn  has  the  drawback  of 
heavy  input-circuit  loading.  To  overcome  this 
disadvantage,  the  cathode  follower  is  made  to 
order.  The  high  input  impedance  of  a  6C-1  cathode 
follower  stage  decreases  loading  of  the  tuned 
circuit,  resulting  in  greatly  increased  input- 
signal  voltage,  and  improved  r.f.  selectivity; 
while  the  low  output  impedance  of  the  cathojle 
follower  matches  the  input  of  the  grounded-giid 
stage.  Our  experience  has  shown  the  combination 
to  be  relatively  noise  free. 

Mixer 

Since  the  grounded-grid  amplifier  and  cathode 
follower  proved  so  successful,  it  was  decided  to 
try  the  combination  in  the  mixer  stage.  Cathode 
injection  looked  like  a  good  bet.  *  The  circuit 
was  incorporated  in  the  modified  HRO-5  and  it

The  Multimatch  Antenna  System 

Unique  Design  Providing  Essentially  Constant  Impedance 
Over  Several  Bands 

BY  CHESTER  L.  BUCHANAN.*  W3DZZ 


•  For  a  long  lime,  hams  have  been 
searching  for  a  single  antenna  that  could 
be  fed  efficiently  Mith  a  low-impedance 
transmission  line  on  several  bands.  At 
last  a  simple  but  ingenious  design  by 
W3DZZ  provides  a  solution.  He  has  ap- 
plied some  well-known  but  neglected 
principles  to  both  wire  and  parasitic- 
beam  antennas. 


RADIO  transmitters  and  receivers  have  en- 
joyed rapid  development  in  flexibility  to 
-  the  point  where  changing  bands  is  a  matter 
of  only  spinning  a  dial  or  two  and  flipping  a 
couple  of  switches.  In  contrast,  the  operation  of  a 
single  antenna  on  several  bands  is  usually  done 
only  at  the  expense  of  high  standing  waves  on 
the  feed  line,  because  of  the  wide  variation  in 
antenna  feed-point  impedance  from  band  to 
band. 

Some  work  done  by  the  author  several  years 
ago  in  connection  with  a  dual-band  parasitic 
array^  has  led  to  the  development  of  a  simple 
wire  antenna  covering  five  bands,  from  80  to 
10  meters.  This  antenna  can  be  fed  with  a  low- 
impedance  transmission  line  without  incurring 
excessive  s.w.r.  on  any  of  these  bands. 

Basic  Design 

The  fundamental  principle  of  the  system  can 
be  explained  with  the  aid  of  Fig.  1.  In  Fig.  lA,

some  frequency  /i.  This  dipole  is  terminated  in 
lumped-constant  trap  circuits  resonant  at  /i. 
Additional  wire  sections,  /12,  extend  beyond  the

the  traps  serve  to  isolate  the  dipole  much  as 
though  insulators  were  inserted  at  these  points.^ 
At  frequencies  much  lower  than  /i,  the  traps 
no   longer   isolate   the   dipole,    but   act   simply

as  loading  inductances  in  a  second  dipole  whose 
electrical  length  is  made  up  of  hi,  hi  and  the 
inductive  reactance  of  the  traps,  as  in  Fig.  IB. 

At  frequencies  much  higher  than  /i,  the  traps 
again  cease  to  isolate  the  sections,  the  traps  now 
acting  as  series  capacitances,  as  in  Fig.  IC. 

Another  important  consideration  in  this  multi- 
band  system  is  that  low  impedance  at  the  center 
feed  point  of  the  antenna  occurs  not  only  at  its 
fundamental  resonance  but  also  at  any  odd 
harmonic  of  the  fundamental. 

By  applying  these  principles,  and  by  proper 
selection  of  the  values  of  L  and  C  in  the  traps, 
and  choice  of  lengths  for  hi  and  h-i,  it  has  been 
possible  to  arrive  at  a  design  where  the  system 
operates  as  follows: 

1)  Sections  hi  form  a  half-wave  diijole  resonant

in  the  40-meter  band.  The 
traps,  resonant  at  the  same 
frequency,  isolate  this  dipole 
from  the  outer  sections. 

2)  The  inductive  reactance 
of  the  traps  is  such  that  the 
entire  sj-stem,  including  sec- 
tions ho,  resonates  as  a  loaded 
half-wave  dipole  for  the  80- 
meter  band. 

3)  The  capacitive  reactance 
of  the  traps  at  higher  frequen- 
cies is  such  that  the  entire 
system  resonates  as  a  3/2 
wavelength  antenna  on  20, 
5/2  wavelength  on  15,  and  7/2  wavelength  on  10 
meters. 

The  antenna  is  fed  with  75-ohm  Twin-Lead, 
and  Fig.  2  shows  the  results  of  s.w.r.  measure-

polystyrene  is  also  flowed  into  a  series  of  holes

ductor is  weatherproof ed  by  molding  it  in  insu-

used,  of  course.  As  an  e.xample,  a  conventional

would,  however,  add  to  the  weight.

are  given  in  Fig.  lA. 

Trap  Construction 

The  values  of  C  and  L  used  in  the  traps  are 
quite  critical.  The  capacitance  should  first  l)e 
adjusted  accurately  to  60  fxfxi..  then  the  in- 
ductance should  be  trimmed  until  the  trap 
resonates  at  7200  kc.  This  should  be  done  before 
the  traps  are  inserted  in  the  antenna.  The  in- 
ductance will  be  approximatel}' 
8.2  ^h.  The  traps  made  by  the 
author  are  (3  inches  long  and 
weigh  only  6  ounces  and  the  Q 
is  well  over  100.  They  will  with- 
stand the  voltage  developed  by 
a  l-kw.  transmitter.  Samples 
are  shown  in  the  photograph. 
The  wire-antenna  capacitor  is 
made  up  of  concentric  lengths 
of  1-inch  and  ^-inch  alumi- 
num tubing  separated  by  poly- 
stj-rene    tubing   with    J/g-inch 


A  Three-Band  Parasitic  Beam 

The  principle  of  isolating  sections  of  an  antenna 
with  resonant  traps  has  been  applied  to  a  parasitic 
beam  antenna  that  operates  on  10,  15  and  20 
meters.  This  array  with  dimensions  is  sketched 
in  Fig.  3.  The  arraj'  is  a  five-element  job  on  10 
meters,  with  two  reflectors  spaced  approximateh' 
0.15  wavelength,  and  two  directors  spaced  ap- 
proximately 0.2  wavelength.  On  the  other  two 
bands,  three  elements  are  active.  On  15  meters, 
spacings  are  approximately  0.22  wavelength  for 
the  reflector  and  0.29  for  the  director.  On  20 
meters,  the  approximate  spacings  are  0.14  and 
0.2,  respectively. 

Fig.  4  shows  a  breakdown  of  a  suggested 
method  of  construction  of  the  three  main  ele- 
ments. Each  element  starts  out  with  a  12-foot 
center  section  to  which  various  sections  are 
added  at  each  end.  Provision  is  made  for  adjust- 
ing the  length  from  the  center  of  the  element 
to  the  first  (28-Mc.)  trap,  the  length  between 
traps,  and  the  section  on  the  outside  of  the  second 
(21-Mc.)  trap.  The  photograph  shows  an  exam- 
ple of  the  array  traps  used  by  the  author.  Here,

The  "Hidden  Gem" 

A  Field- Strength  Indicator  for  Mobiles 

BY  CLIFFORD  ABEL,*  W8IWB 


•  All  niobileers  will  find  this  little  gadget 
mighty  convenient  and  valuable.  A 
simple  field-strength  indicator  helps  to 
tell  you  when  you  are  getting  the  most 
out  of  your  rig  on  any  band. 


ONE  of  the  main  problems  besetting  today's 
struggling  mobileer  is  getting  maximum 
power  output  from  his  installed  equipment. 
Considering  the  relatively  low-power  input  and 
poor  antenna  radiation  efficiency  with  which  he 
must  contend,  the  mobile  operator  can  ill  afford 
the  additional  losses  of  improper  antenna  or 
transmitter  tuning.  After  the  transmitter  and 
antenna  of  his  choice  have  been  installed,  he  must 
make  the  most  of  it  no  matter  what  his  power 
input  or  what  the  inherent  efficiency  of  his  an- 
tenna system  may  be.  What  could  be  a  better 
method  of  making  the  most  of  it  than  by  measur- 
ing the  relative  strength  of  the  radiated  field  as 


The  field-strength  indicator  is  mounted  on  the 
inside  of  the  glove-compartment  door,  oriented  so  that 
it  can  be  seen  easily  from  the  driver's  seat.  The  an- 
tenna banana  plug  is  at  the  left  rear,  the  sensitivity 
control  is  at  the  upper  left,  and  the  slug  screw  of  the  in- 
ductor at  the  lower  right.  Small  holes  in  the  top  of  the 
can  provide  access  to  the  sheet-metal  screws  holding 
the  unit  to  the  glove-compartment  cover. 

the  antenna  and  transmitter  tuning  are  changed ! 
In  other  words,  use  a  field- strength  indicator. 

Nearly  any  type  of  field-strength  meter  could 
be  used  to  do  the  job.  A  de  luxe  commercial 
meter  borrowed  from  a  fixed  station  or  a  simple 
crystal  rectifier  in  series  with  the  low-current 
scale  on  j'our  volt-ohmmeter  will  work  with  a 
proper  pick-up  antenna.  But  most  desirable  is  a 

*  783rd  AC&W  Squadron.  Charleston,  W.  Va. 


unit  which  is  an  integral  component  of  the 
mobile  system  —  an  indicator  that  will  give  a 
relative  power-output  measurement  from  minute 
to  minute,  and  day  to  day. 

You  may  have  abeady  been  convinced  of  the 
value  of  a  mobile  field-strength  indicator,  but 
then  the  question  arises  of  where  to  put  the 
thing.  Your  under-dash  mounting  space  may  be 
pretty  well  used  up  by  now,  so  why  not  stick 
it  in  the  glove  compartment?  In  there  it's  com- 
pletely out  of  the  way  and  out  of  sight.  Better

yet,  if  you  mount  it  on  the  inside  top  of  the  glove- 
compartment  door,  it  will  take  up  little  of  the 
useful  space  in  the  compartment.  When  the  door 
is  opened,  the  indicator  drops  down  into  a  posi- 
tion where  the  scale  can  be  seen  easily,  and  the 
compartment  light  illuminates  the  meter  for 
nighttime  operation.  Two  small  sheet-metal 
screws  can  be  used  for  mounting. 

Construction 

The  circuit,  shown  in  Fig.  1,  is  conventional, 
and  none  of  the  values  is  critical.  Nearly  any 
type  of  crystal  detector  can  be  used,  and  the 
meter  movement  can  be  anything  from  50  ;ua.  to 
2  ma.  or  more,  depending  upon  the  size  and 
placement  of  the  pick-up  antenna  and  your 
transmitter  power  output.  All  the  components 
are  housed  in  a  small  tin  can.  The  round  can  is 
available  and  cheap,  and  takes  up  less  space  than 
other  types  of  housing.  It  doesn't  look  half  bad 
if  it's  new  and  shiny,  or  if  you  give  it  a  coat  of 
black  crackle  paint.  The  can  is  the  8V2-ounce 
size.  That's  the  same  diameter  as  a  can  of  Camp- 
bell's soup,  but  somewhat  shorter.  Of  course,  the 
smaller  the  meter  you  can  find,  the  smaller  the 
can  may  be.  The  pick-up  antenna  lead-in  comes 
in  to  a  banana  plug.  Thus,  the  whole  assembly 
can  be  detached  quicklj'  from  the  car  and  can 
be  used  anywhere  that  a  field-strength  indicator 
might  be  needed.  By  using  the  terminals  on  all 
the  fixed-mounted  components  and  one  3-point 
soldering-terminal  strip,  all  the  other  components 
may  be  mounted  easily  and  compactly.

QST  for 


Transmitter  Hunting  —  Seattle  Style 

A  De  Luxe  D.F.  System  for  Ten  Meters 

BY  J.  ALAN  DUNCAN,*  W70TA 


•This  story  on  hiddcn-transnii  t  itr 
hunting  should  strike  a  response 
in  every  mobile  ham.  It  includes,  along 
M'ith  other  useful  information,  descrip- 
tions of  a  special  S-mcter  circuit  and  a 
dirccticin-findinji  loop  with  suggestions 
for  mounting. 


WITH  civil-defense  and  disaster-relief  train- 
ing on  the  steady  increase  throughout  the 
nation,  it  becomes  more  and  more  neces- 
sary that  amateur  mobile  stations  be  kept  ever 
alert  and  active,  so  they  may  supply  that  vital 
communication  link  so  important  if  the  situation 
should  arise.  Hidden-transmitter  hunting  has 
been  found  to  be  one  of  the  best  drills  for  keeping 
the  moi)iles  trained  for  this  type  of  activity, 
because  it  develops  the  qualities  required  for 
successful  emergency  mobile  communication.  It 
also  affords  more  thrills,  more  opportunity  for 
technical  development,  and  more  participation 
by  the  whole  family,  than  most  other  phases  of 
amateur  radio.  The  mobile  operators  in  the  radio 
clubs  of  Seattle,  Washington,  have  been  kept 
active  on  29  Ale.  almost  continually  since  Don 
Newman,  W7C0,  first  brought  hidden-transmit- 
ter hunting  to  Seattle  some  five  years  ago. 

Various  methods  and  technirjues  are  used  to 
locate  the  hidden  transmitter,  depending  upon 
the  equipment  on  hand  and  the  ingenuit.y  of  the 
hunter.  Some  mobileers  do  remarkat)ly  well  with 
just  their  transmitting  whips,  using  the  direc- 
tional characteristics  of  the  car,  and  by  determin- 
ing the  signal  strength  by  ear.  The  author  prefers 
a  more  exact  method,  however,  and  describes 
the  following  equipment  and  tracking  technique 
for  those  moi)ileers  who  would  use  a  more  scien- 
tific approach  to  this  exciting  sport. 

The  Loop 

Essentially,  a  directional  loop  and  a  signal- 
strength  meter  are  the  required  auxiliary  equip- 
ment for  successful  hunting.  The  author's  loop 
is  a  one-turn  resonant  circuit,  nine  inches  in 
diameter,  requiring  about  65  fx/if.  of  capacity 
to  tune  it  to  29  Mc.  The  signal  is  fed  from  the 
loop  to  the  receiver  through  a  50-ohm  coaxial 
cable  which  is  gamma-matched  to  the  loop.  Fig. 
1  shows  the  loop  dimensions  and  the  method  of 
coupling  the  coaxial  cable  to  it.  The  loop  diameter 
is  not  especiallj'  critical  so  long  as  it  is  kept  small 
(under  about  10  inches),  and  am'  discrepancy 
may  be  compensated  for  in  the  adjustment  of  the 
variable  capacitor.  The  dimension  of  the  coupling

tap  is  shown  onlj-  as  a  starting  value.  Further 
adjustment  will  be  required  in  the  tuning  process. 
For  the  tuning  capacity  the  author  is  using  a 
oO-jUMf-  fixed  capacitor  in  parallel  with  a  25-MMf- 
variable  capacitor  (Hammarlund  .\PC-25).  This 
tuning  arrangement  was  arrived  at  after  some 
experimenting,  and  has  been  found  to  be  very 
steady  and  extremely  eas\'  to  tune.  The  capacitor 
combination  is  enclosed  in  an  old  surplus  capaci- 
tor casing  (Sangamo  type  F-2)  with  the  original 
capacitor  removed.  With  a  new  sealed-in  fiber 


The  loop  assembly  mounted  on  WTOTA's  car.  The 
mounting  is  a  triangular  framework  of  tubing  or  rods 
with  plates  that  hook  over  the  window  frame,  and  a 
rubber  suction  cup  at  the  bottom.  The  loop  mast  re- 
volves in  a  section  of  tubing.  Large  rubber  bands  to  the 
external  rear-view  mirror  and  door  handle  help  to  hold 
the  assembly  in  place.  *

housing. 

The  type  of  stock  used,  the  method  of  mount- 
ing the  loop  to  the  car,  the  dimensions  of  the 
mount,  etc.,  will  certainly  varj-  with  desire  and 
circumstances.  The  author  constructed  his  loop 
and  mount  entirely  of  duralumin  tubing,  though 
most  hunters  use  copper  for  the  loop.  The  style 
and  mounting  are  shown  in  the  illustration. 

Adjustment 

Tuning  the  loop  is  a  very  simple  process.

tenna  terminal  of  the  receiver.  Radiate  a  29-Mc. 
signal  with  a  grid-dipper,  r.f.  signal  generator, 
or  some  other  calibrated  source,  and  tune  the 
loop  to  res;)nance  as  indicated  by  maximum  sig- 
nal. The  loop  should  also  be  rotated  for  maximum, 
and  then  rocked  back  and  forth  across  maximum 
as  the  capacitor  is  being  adjusted.  Then  adjust 
the  gamma  match  by  moving  the  connection 
back  and  forth  along  the  loop  until  maximum 
transfer  is  indicated.  This  may  throw  the  loop 
off  resonance,  so  the  processss  should  be  repeated 
until  neither  causes  any  noticeable  improvement. 
The  loop  should  be  tuned  ver}^  carefully,  other- 
wise a  sharp  null  may  not  be  obtained.  Although 
the  maximum  signal  is  used  when  tuning  the 
loop,  the  minimum  signal  (null)  is  used  when 
locating  the  hidden  transmitter.  This  is  because 
the  angle  of  minimum  is  so  much  smaller  than 
the  angle  of  maximum  signal. 

S-Meter 

Difficulty  is  usually  encountered  in  trying  to 
tell  a  difference  between  maximum  and  minimum 
signal  by  ear  as  the  hunter  closes  in,  and  a  signal- 
strength  meter  becomes  very  desirable.  A  meter 
in  the  cathode  circuit  of  one  of  the  a. v.c. -con- 
trolled tubes  was  tried,  but  the  change  in  deflec- 
tion from  maximum  to  minimum  signal,  as  the 
hidden  transmitter  was  approached,  was  as  in- 
distinguishable as  by  the  aural  method.  The 
author  finally  came  up  with  the  amplifier-bridge 
circuit  shown  in  Fig.  2.  This  system  operates  by 
sampling  the  a. v.c.  voltage,  amplifying  the  volt- 
age change  causing  a  change  in  the  jjlate  resist- 
ance of  the  6C-4  tube.  This  change  in  plate  re- 
sistance upsets  the  balance  of  the  bridge  circuit 
(see  equivalent  circuit  in  Fig.  2B),  causing  a  dif- 
ference of  potential  to  exist  between  points  D 
and  B.  The  resulting  current  flow  through  the 
meter  causes  the  needle  to  deflect.  Potentiometer 
Ri  is  a  gain  control  and  governs,  to  a  certain 
extent,  the  amount  of  deflection  of  the  meter. 
Potentiometer  7^2  is  the  zero  adjustment  used 
to  balance  the  bridge.  As  the  signal  of  the  hid- 
den transmitter  changes  in  intensity,  both  the 
gain  and  zero  controls  will  need   adjusting.   A

little  technique  is  involved  in  making  these 
adjustments  during  the  short  transmissions  from 
the  hidden  transmitter,  but  after  a  couple  of

deflection  is  possible  (from  maximum  to  minimum 
signal  during  rotation  of  the  loop)  regardless  of 
whether  the  transmitting  station  is  very  weak 
and  distant  or  whether  he  is  within  a  few  feet. 
As  a  matter  of  fact,  on  a  particular  hunt,  W7C0 
(the  hidden  transmitter  that  night)  was  asked 
by  the  author  at  the  beginning  of  the  hunt  if  he 
was  using  his  mobile  whip  or  his  receiving  antenna 
for  transmitting.  The  hidden  transmitter  operator 
replied  that  the  hunters  would  have  to  loop 
in  and  find  out.  When  the  author  arrived  along- 
side the  hidden  transmitter  and  asked  for  a 
transmission,  he  was  able  to  develop  a  very 
definite  null  (actually  more  than  full-scale  deflec- 
tion) with  the  pointer  directed  at  the  rear  trans- 
mitting antenna,  less  than  four  feet  away. 
None   of   the   leads   in    this   circuit   need    be 


shielded,  and  the  lengths  are  not  critical.  AIbo, 
don't  put  off  making  this  unit  just  because  you 
don't  happen  to  have  a  150-jtta.  meter,  as  some 
of  the  boys  are  using  1-ma.  meters  with  quite 
good  results.  Even  the  GC4  tube  may  be  re- 
placed by  practically  any  other  triode  tube.  Half 
the  fun  is  in  experimenting  with  various  values 
and  components. 

The  S-meter  unit  may  be  housed  in  any 
convenient  chassis  or  box.  The  author  originally 
mounted  his  S-meter  under  the  dash,  next  to  the 
transmitter  control  unit.  This  was  difficult  to 
read  without  stopping  the  car,  so  the  unit  was 
rebuilt  into  a  surplus  pilot's  control  box,  with  the 
meter  mounted  just  above  in  an  old  coil  shield 
can.  This  unit  was  then  hung  on  the  steering 
column.  This  proved  to  be  a  very  handy  location. 
Finally  a  pilot  lamp  was  installed  so  as  to  illumi- 
nate the  meter  and  is  ver}-  helpful  for  night 
hunting. 

\'arious  tochniques  are  used  to  track  down 
the  hidden  transmitter  or  "bunny"  as  he  is  re- 
ferred to  in  Seattle.  The  author  has  used  the 
triangulating  method  of  pin-pointing  the  bunny 
l)v  using  a  map,  etc.,  but  doesn't  recorrunend  it 
because  it  is  too  undependable.  This  is  especially 
true  in  hilly  country.  Such  phenomena  as  reflec- 
tions, wave-polarization  changes,  and  antenna 
effects  will  cause  some  readings  to  be  in  error  by 
a  considerable  amount.  This  makes  a  very  dis- 
couraging triangulation  plot  on  a  map,  in  addition 
to  a  possible  waste  of  considerable  time.  The 
errors  reduce  to  insignificance  as  the  hidden 
transmitter  is  approached,  however,  and  regard- 
less of  the  system  or  technique  used,  if  complete 
trust  is  placed  in  the  loop,  the  hunter  should 
eventuall}'  arrive.

Unidirectional  Loops  for  Transmitter 

Hunting 

Less  Guesswork  in  Mobile  D.F.  Work 

BY  WARREN  U.  AMFAHR,*  W0WLR 


MOBILE  hams  in  the  Wichita  area  have  Ijeen 
running  10-meter  liidden-transmitter  hunts 
each  week  for  the  past  three  years  or 
more.  Not  long  after  these  hunts  were  inaugu- 
rated, it  became  evident  that  the  affairs  were 
rapidly  degenerating  into  rat  races.  Under  the 
usual  rules,  where  the  first  car  to  arrive  at  the 
site  of  the  transmitter  was  declared  the  winner, 
the  honor  sj-stem  for  compliance  with  existing 
speed  limits  failed  completely.  It  became  obvious 
that  the  contests  would  have  to  be  conducted 
along  different  lines,  if  they  were  to  be  continued 
on  a  safe  and  sane  basis.  In  the  interest  of  public 
safety,  w^e  felt  that  we  could  not  continue  to  en-

realized  too  that  our  call  license  plates  and  long 


The  unidirectional  10-meter  d.f.  loop  is  a  simple 
affair,  consisting  of  two  turns  of  copper  tubing  mounted 
on  an  insulating  rod.  Directivity  is  adjusted  by  the 
trimmer  condenser  at  the  center. 

whip  antennas  could  easily  draw  attention  to  us 
in  any  adverse  publicity. 

For  some  time  now,  we  have  been  operating 
under  a  scheme  in  which  precision  and  skill  are 
substituted  for  speed  and  recklessness.  The 
time  element  has  been  eliminated  entirely,  and 
all  hunts  are  now  based  on  the  mileage  covered 

*  3096  Clifton,  Wichita  10,  Kansas. 


•  Thi.s  article  not  only  describes  the  con- 
struction and  use  of  a  d.f.  loop  that 
eliminates  much  of  the  uncertainty  in 
making  "fixes"  in  fox  hunts,  but  it  also 
contains  some  interesting  observations 
regarding  the  conducting  of  this  highly 
popular  activity. 


between  a  common  starting  point  for  all  cars  and 
the  hidden  transmitter.  Speedometer  readings 
are  recorded  at  the  starting  point,  and  again 
when  the  car  reaches  the  objective.  There  is  no 
time  limit,  and  the  winner  is  the  one  who  reaches 
the  hidden-transmitter  site  over  the  shortest 
route. 

The  changes  in  rules  naturally  have  brought 
about  a  search  for  more  accurate  direction- 
finding  gear,  rather  than  speedier  cars.  Perhaps 
the  most  important  result  has  been  the  adoption 
of  a  unidirectional  loop  antenna  by  the  hunters. 
It  has  eliminated  the  possibility  of  starting  out 
in  exactly  the  opposite  direction,  and  reduced  the 
probabiUty  of  overshooting  the  transmitter.  In 
eliminating  the  necessity  for  triangulation,  it  has 
simphfied  the  limiting  technique,  and  placed  it 
more  within  the  grasp  of  the  YL  and  Jr.  Ops. 

The  unidirectional  loop  antenna  works  on 
rather  well-known  principles.  In  simple  terms, 
a  loop  that  is  not  accurately  balanced  in  respect 
to  ground  will  exhibit  two  modes  of  operation. 
One  mode  is  that  of  a  true  loop,  while  the  other  is 
that  of  an  essentially  nondirectional  vertical  an- 
tenna of  small  dimensions.  The  voltages  intro- 
duced by  the  two  modes  are  out  of  phase,  and 
will  add  or  subtract,  depending  upon  the  direction 
from  which  the  wave  is  arriving. 

The  theoretical  true  loop  pattern  is  illustrated 
in  Fig.  lA.  When  the  voltage  introduced  by  the 
antenna  mode  is  large,  the  nondirectional  pattern 
of  the  vertical-antenna  mode  predominates,  and 
the  loop  will  show  little  directivit}',  as  shown  in 
Fig.  IB.  When  the  antenna  effect  is  small,  one  of 
the  loop  lobes  will  be  reduced,  while  the  other 
will  be  correspondingly  enlarged  (see  Fig.  IC). 
\\'hen  the  voltages  introduced  by  the  two  modes 
are  equal  and  90  degrees  out  of  phase,  one  of  the 
lobes  will  be  canceled  out,  making  the  loop 
unidirectional,  as  indicated  in  the  pattern  of 
Fig.  ID. 

Since  the  loop  pick-up  will  usually  be  pre- 
dominant, when  the  dimensions  of  the  loop  are 
small  in  terms  of  wavelength,  the  loop  and  an- 
tenna effects  can  be  balanced  by  detuning  the 


28

loop  so  as  to  reduce  its  pick-up  to  equal  that 
introduced  bj'  the  antenna  effect. 

The  loop  shown  in  the  photograph  consists 
of  two  turns  of  14-inch  copper  tubing,  11  inches 
in   diameter.   The  two   ends   are   flattened   out,

plane  of  the  loop. 

and  fastened  to  opposite  sides  of  a  1-inch  diameter 
insulating  rod  that  serves  as  a  mounting.  The 
center  of  the  loop  is  l)roken,  and  a  20-/.iAtf.  mica 
trimmer  is  inserted  in  series.  The  ends  of  the 
tubing  at  the  break  are  supported  in  a  slot  cut  in 
the  end  of  the  insulating  rod.  The  rod  of  the  loop 
shown  in  the  photograph  is  a  piece  of  1-inch 
polystyrene.  However,  a  piece  of  ordinary  broom- 
stick will  provide  adequate  insulation. 

The  loop  is  connected  to  the  receiver  input 
with  a  length  of  coax  cable.  After  the  receiver 
has  been  tuned  to  the  desired  operating  fre- 
quenc}^,  the  trimmer  condenser  in  the  loop  should 
be  adjusted  for  ma.\imum  background  noise.  If 
no  peak  in  noise  can  be  found,  the  condenser 
range  value  should  be  changed.  An  11-inch  loop 
should  require  no  more  than  5  to  15  fjLfxi. 

Once  a  noise  peak  has  been  established,  a 
signal  and  the  receiver  S-meter  should  be  em- 
ployed. (If  the  mobile  receiver  is  not  equipped 
with  an  S-meter,   the  circuit  of  Fig.   2  can  be

■  S-meter  circuit  widely  used  in  transmitter 


added.)  The  capacity  of  the  loop  condenser 
should  then  be  carefully  reduced  until  the  loop 
acquires  a  unidirectional  characteristic.  The 
final  setting  of  the  trimmer  condenser  depends 
upon  the  front-to-back  ratio  desired.  Complete 
cancellation  of  signals  from  the  back  can  be  ac- 


quired at  the  expense  of  a  certain  amount  of 
frontal  signal  pick-up. 

This  type  of  loop  is,  of  course,  oriented  for 
maximum  signal  in  contrast  to  a  conventional 
d.f.  loop  which  is  usually  worked  on  the  signal 
null.  In  the  use  of  the  loop,  it  will  be  found  that 
resonant  antennas  or  other  objects  are  highly 
capable  of  receiving  signal  energy  and  reradiating 
it.  The  possibility  of  the  loop  receiving  reflected 
signals  from  the  mobile  whip  should  be  thor- 
oughly investigated.  Usually,  the  loop  when 
used  on  one  side  of  the  car  will  be  more  suscepti- 
Vjle  to  whip  reflections  than  it  will  be  on  the 
other.  This  depends  upon  the  car  body  contour 
and  the  distance  between  the  loop  and  the  whip. 
In  some  installations,  it  may  be  necessary  to  pull 
the  whip  down  while  taking  loop  bearings. 

In  the  process  of  hunting,  it  is  advantageous 
to  keep  the  hidden  transmitter  on  the  loop  side 
of  the  car.  The  ma,\imum-to-minimum  signal, 
and  the  exact  direction,  will  be  less  pronounced 
if  the  loop  has  to  look  across  a  reflecting  or  dif- 
fusing car  roof.  Whenever  the  loop  is  used  in  the 
vicinity  of  a  strong  signal,  some  means  of  at- 
tenuating the  antenna  circuit  should  be  used, 
rather  than  to  decrease  the  S-meter  sensitivity. 
Various  resistor  values,  switched  in  parallel  with 
the  antenna  ini)ut,  will  achieve  this. 

Those  who  organize,  or  participate  in,  this 
popular  activity  will  find  that  many  headaches 
will  be  avoided  if  the  rules  place  strong  restriction 
against  hunting  or  hiding  on  private  property. 
We  have  also  found  it  highly  advisable  to  notify 
the  local  police  in  advance  of  a  scheduled  hunt. 
Summer-night  hunts,  with  dozens  of  dangling 
loops  and  seeking  searchlights,  can  load  the 
police  telephone  circuits  with  curious  inquiries!

Meet  the  S.W.R.  Bridge 

Simple  Instrument  for  Adjusting  Antenna  Circuits 
BY  LEWIS  G.  McCOY.  WIICP 


•  Here  is  a  nontechnical  description  of 
ho'w  to  build  and  use  a  standing-wave- 
ratio  bridge,  an  inexpensive  instrument 
that  is  worth  many  times  the  small  out- 
lay for  its  construction.  The  use  of  such  a 
bridge  will  help  you  to  solve  some  an- 
tenna-circuit problems  that  can  be 
solved  in  no  other  wav. 


DID  you  ever  stop  to  wonder  if  your  trans- 
mitter was  properly  coupled  and  matched 
into  the  antenna  or  antenna  coupler?  If 
3'ou're  the  average  ham,  this  problem  has  prob- 
ably bothered  you  a  great  deal.  Well,  there  is 
one  simple  way  to  find  out,  and  it  won't  cost 
you  more  than  a  few  dollars. 

When  working  with  antennas  and  antenna 
couplers,  the  standing-wave-ratio  bridge  is  prac- 
tically an  indispensable  instrument.  With  the 
s.w.r.  bridge,  it  is  possible  to  know  when  the 
coax  line  between  the  transmitter  and  antenna 
coupler  is  matched,  or  if  a  coax-fed  antenna  is 
properly  matched  to  the  feed  line.  When  a  low- 


pass  filter  is  used  to  attenuate  harmonics,  it  is 
important  to  keep  the  s.w.r.  low  in  the  connect- 
ing line,  otherwise  there  is  always  the  possibility 
that  the  filter  may  break  down.  By  setting  the 
system  up  with  the  s.w.r.  bridge,  one  can  be  sure 
the  filter  will  be  working  in  a  line  with  a  low 
s.w.r.  It  has  been  mentioned  that  the  s.w.r. 
bridge  only  costs  a  couple  of  dollars;  another 
attraction  is  that  the  unit  is  very  easy  to  build. 

S.W.R.  Bridge  Construction 

As  can  be  seen  from  Fig.  1  and  the  photo- 
graphs, the  bridge  consists  of  four  resistors,  two

clip-on  point  for  the  minus  side  of  I  lie  meter.

condensers,  a  cr3'stal  diode,  an  isolantite  stand- 
off, two  coax  connectors  and  a  chassis.  A  tip 
jack  is  used  for  the  -|-  meter  terminal,  and  the 
chassis  case  for  the  —  side.  The  value  of  Ri  will 
depend  on  the  type  of  coax  the  bridge  is  designed 
for.  If  for  52-ohm  line,  then  Ri  would  be  a  50- 
ohm  resistor,  and  the  value  would  be  75  ohms 
if  72-ohm  coax  is  used.  Whichever  type  is  used, 
buy  two  resistors,  because  one  will  be  used  in 
the  bridge  and  the  other  for  testing  the  unit. 
All  of  the  resistors  are  l-i  watt,  and  be  sure  they 
are  composition-type  and  not  wire-wound. 

In  the  construction  of  the  bridge,  the  resistors 
and  the  crystal  should  be  mounted  at  right 
angles  to  each  other,  as  shown  in  the  photograph. 
This  is  done  to  avoid  stray  coupling  that  might 
give  erroneous  readings.  The  unit  shown  in  the 
photographs  was  built  in  a  4  X  2  X  H^c-inch 
channel-lock  box.  If  this  size  is  used,  it  should 
be  simple  to  follow  the  layout  in  the  photograph. 

When  soldering  the  leads  of  the  cr^'stal  diode, 
the  leads  should  he  held  bj'  a  pair  of  pliers  in 
order  to  conduct  the  heat  away  from  the  crystal. 
Don't  hold  the  iron  to  the  soldering  point  any 
longer  than  necessary,  as  it  is  easy  to  damage 
the  crj'stal  with  excessive  heat. 

Testing 

The  com])leted  unit  is  connected  to  the  trans- 
mitter with  a  piece  of  coax  of  the  proper  impe-

QST  for 


dance,  the  coax  going  to  the  input  side  of  the 
bridge.  A  0-1  milHammeter  is  connected  to  the 
bridge  with  the  +  side  of  the  meter  going  to  the 
pin  jack  and  the  —  side  to  the  chassis.  The  out- 
put side  of  the  bridge  is  left  open. 

The  ne.xt  step  is  to  adjust  the  transmitter  out- 
put so  that  a  full-scale  reading  is  obtained  on 
the  0-1  meter.  A  very  small  amount  of  r.f.  is 
needed  for  this,  so  it  may  be  necessary  to  turn 
off  the  final  amplifier  and  just  allow  the  driver 
stage  to  run.  If  the  transmitter  has  a  drive  con- 
trol, such  as  the  Viking  and  Viking  Ranger,  it  is 
merely  a  matter  of  advancing  the  drive  control 
to  a  point  where  full-scale  reading  is  obtained. 
With  the  meter  reading  full  scale,  the  test  re- 
sistor is  connected  between  the  output  coax 
connector's  inner  conductor  and  the  shell  or 
ground  side  of  the  connector.  The  reading  on 
the  meter  should  drop  to,  or  near,  zero.  If  the 
reading  is  appreciably  above  zero,  there  is  stray 
coupling  between  the  resistor  arms  in  the  bridge, 
and  their  placement  should  be  carefully  checked 
and  changed  if  necessary. 

Several  different  resistors  of  the  same  value 
were  tried  in  testing  the  unit  shown,  and  in 
every  case  the  reading  dropped  to  zero,  indicat- 
ing that  the  10  per  cent  tolerances  were  close 
enough  for  the  purpost^. 

Using  the  S.W.R.  Bridge 

For  an  e.xample  of  using  the  bridge,  let's  as- 
sume we  have  an  antenna  fed  with  open-wire 
line,  and  that  an  antenna  coupler  is  used  with 


the  open-wire  line.  A  length  of  coaxial  line  con- 
nects the  transmitter  to  the  coupler.  Such  a  sj's- 
tem  is  illustrated  in  Fig.  2A.  Our  problem  is  to 


Inside  view  of  the  s.w.r.  bridge.  The  resistor  connected 
between  the  inner  conductor  pins  of  the  coax  sockets  is 
Ri.  One  of  the  47-ohm  resistors  is  on  the  right,  connected 
between  the  inner  conductor  pin  and  the  junction  of  a 
0.001-uf.  disk  condenser  and  the  other  47-ohm  resistor. 
Note  the  three  resistors  are  mounted  at  right  angles 
to  each  other.  The  1000-ohm  resistor  at  the  lower  left  is 
connected  between  the  tie  point  andthc  meter  terminal.

take  the  power  out  of  the  final  amplifier  and  get 
it  to  the  antenna  coupler,  with  as  little  loss  on 
the  way  as  possible. 

The  Novice  will  probably  wonder  why  an 
antenna  coupler  is  used  instead  of  connecting 
the  open-wire  line  directly  to  the  output  termi- 
nals of  the  transmitter.  The  feeders  could  be 
connected  directly  to  the  transmitter,  but  it 
greatly  simplifies  coupling  problems  to  use  an 
external  antenna  coupler,  particularlj'  if  the 
antenna  is  to  be  operated  on  more  than  one  band. 

Where  most  amateurs  run  into  trouble  with  a 
system  such  as  this  is  in  adjusting  the  coupler 
and  getting  the  transmitter  to  load.  With  an 
s.w.r.  bridge  inserted  in  the  coax  line  between 
the  rig  and  the  coupler,  it  l^ecomes  an  easy  job 
to  adjust  the  coupler  to  the  proper  operating 
values.  An  ideal  set-up,  for  adjusting  the  coupler, 
and  the  link  at  the  coupler,  is  shown  at  Fig.  2B. 
This  coupler,  incidentally,  is  the  unit  described 
at  Fig.  13-32  in  the  1953,  '54,  and  '55  editions  of 
The  Radio  Amateur's  Handbook.  Complete  de- 
tails are  given  for  component  values. 

The  bridge  of  Fig.  1  does  not  make  actual 
s.w.r.  measurements  —  this  takes  a  more  com- 
plicated bridge  —  but  it  shows  when  the  s.w.r. 
is  a  minimum  and  as  such  is  used  to  adjust  the 
coupling  system  for  a  good  match. 

The  first  step  is  to  set  the  meter  to  full-scale 
reading  with  the  output  side  of  the  bridge  dis- 
connected. Once  full-scale  reading  is  set  on  the 
meter,  the  transmitter  controls  are  not  touched 
again  for  the  test  unless  the  frequency  is  changed. 
The  coax  line  from  the  antenna  coupler  link  is 
then  attached  to  the  output  side  of  the  bridge. 
The  feed-line  taps  are  attached  to  Lo  at  or  near 
the  outside  turns  of  the  coil,  making  sure  they 
are  equidistant  from  the  coil  ends.  The  coupler 
capacitor  Co  is  then  tuned  for  minimum  reading 
on  the  milliammeter.  When  this  point  is  reached,

ADJUSTING  LOW-PASS  FILTERS 

To  adjust  a  low-pass  filter  for  maximum  atten- 
uation of  harmonies  falling  in  a  particular  TV 
channel,  it  is  often  necessary  to  unsolder  the 
coils  used  in  the  low-pass  and  adjust  their  in- 
ductance using  a  grid-dip  meter.  A  short-cut  that 
possibly  provides  more  accurate  tuning  is  to  in- 
sert the  filter  into  the  TV  receiver  antenna  feed 
line  and  tune  for  maximum  attenuation  of  the 
TV  picture  on  the  critical  channel.  This  method 
may  be  criticized  by  those  who  take  a  dim  view 
of  the  mismatch  created  by  inserting  a  52-  or 
75-ohm  low-pass  in  a  300  ohm  line  —  but  it 
works!  — Kenneth  Montgomery,  W5ABY 

MORE  ON  SIGNAL  SHIFTER  TVI 
SUPPRESSION 

Some  months  ago  a  method  was  shown  for  re- 
ducing harmonic  radiation  from  the  Meissner 
Signal  Shifter.'  It  was  tried  and  found  inade- 
quate in  suppressing  harmonics  which  interfered 
with  Channels  2  and  4  at  this  location. 

It  was  found  that  quite  a  bit  of  r.f.  was  being 
picked  up  by  five  115- volt  a.c.  leads  which  go  to 
the  rear  of  the  chassis  from  the  switch  on  the 
front  panel.  These  were  inserted  separately  in 
shielded  copper  braid  grounded  in  the  center  and 
at  both  ends.  This  reduced  r.f.  in  the  a.c.  line 
about  50  per  cent. 

Further  inspection  revealed  that  the  output 
link  coils  in  the  turret  are  closely  coupled  to  the 
plate  in  luctances  of  the  807  stage.  It  was  reasoned 
that  if  the  output  coils  were  tuned,  the  harmonics 
should  be  considerably  reduced.  An  external  as- 
sembly mounted  in  a  small  aluminum  box  (Fig.l) 
was  used  to  accomplish  this  objective.

nected from  the  output  side  of  the  tapped  coil  to

TVI  COMPLAINT 

2ICO  N.  Mason  Ave. 
Chicago,  111. 
Editor,  QST: 

On  Friday,  January  21,  195.5,  I  received  rather  unique 
publicity  in  one  of  Chicago's  newspapers  about  a  case  of 
TVI  that  came  to  me  via  the  Presidential  ofhce  in  Washing- 
ton, D.  C.  Apparently  some  of  the  other  news  services 
picked  up  this  "scoop,"  adding  or  subtracting  their  own 
twist,  resulting  in  nation-wide  radio  and  newspaper  pub- 
licity. I  received  considerable  mail  about  this  matter  and 
believe  an  explanation  is  in  order. 

The  transmitter  in  use  here  is  a  Viking  II,  equipped  with 
a  low-pass  filter.  My  operation  is  on  the  40-meter  'phone 
band,  and  I  have  no  interference  on  TV  receivers  in  my 
own  home.  Extensive  checks  have  been  made  with  several 
neighbors  and  no  TVI  was  encountered. 

After  becoming  aware  of  this  much  publicized  case  of 
TVI,  through  the  local  FCC  office,  I  had  my  son,  who  is  a 
TV  engineer  and  also  a  radio  amateur,  conduct  an  investiga- 
tion. The  complainant's  TV  receiver  is  one  of  a  well-known 
manufacturer,  about  six  years  old.  Both  the  audio  and  video 
on  all  channels  (2,  5,  7,  and  9)  were  being  affected  in  the 
same  manner.  My  son  installed  a  high-pass  filter. 

Tests  were  conducted  which  proved  that  the  cause  of 
this  TVI  was  definitely  the  TV  receiver.  The  complainant 
promised  to  contact  the  manufacturer  and  have  them  install 
a  high-pass  filter. 

I  am  writing  this  in  the  hope  that  it  may  clarify  the 
amateurs'  side  of  the  story.  —  Anthony  Shragdl,  W9SEF

A  Mobile  S.S.B.  Receiver  for  80  and  40 

Using  a  Tunable  I.F,  and  Crystal- Converter 

BY  ROBERT  A.  THOMASON,*  W4SUD 


•  Here  is  some  sound  reasoning  on  what 
should  go  into  a  good  receiver  for  niohile 
work,  and  some  suggestions  on  how 
to  work  over  a  BC-453-A  to  meet 
those  requirements.  If  you  have  a  BC- 
453-A  that  is  now  gathering  dust,  this  is 
vour  meat. 


WHAT  FEATURES  would  an  ideal  amateur 
mobile  receiver  have  for  a.m.,  c.w.,  and 
s.s.b.  reception?  While  everyone  might 
not  agree  across  the  board,  the  writer  believes 
they  should  include: 

1)  Exceptional  frequency  stability  (for  s.s.b.). 

2)  Good  selectivity  (2J^  kc.  at  6  db.  down). 

3)  Adequate  sensitivity. 

4)  Plenty  of  bandspread. 

5)  Good  calibration  (reset  witliin  2  kc). 

6)  Built-in  automatic  noise  limiter. 

7)  Automatic  volume  control. 

8)  Stable  b.f.o.  (with  switch  control). 

9)  Separate  a.f.  and  r.f.  gain  controls. 

10)  Independence  of  b.c.  receiver. 

11)  Low  image  response. 

Wail  a  second!  That's  a  lot  of  receiver.  You've 
got  to  make  it  fit  somewhere  in  the  family  jaloi^y 
and  operate  it  from  an  average  car  batterj'.  Well, 
then,  let's  make  the  next  two  features: 

12)  Compactness  (under-dash  mounting). 

13)  Reasonable  power  consumption  (100  ma.  at  2.50  volts). 

Assuming  these  specifications  could  be  met, 
who  could  afford  it?  Also,  the  average  amateur 
does  not  have  the  "know-how"  or  test  equipment 
to  build  it.  So  we  have: 

14)  Moderate  cost. 

15)  Simple  construction. 

This  receiver  was  realized  in  the  writer's  mobile 
station  by  converting  a  BC-  !53-.\  low-frequency 
(190-550  kc.)  Command  receiver. 

At  this  point,  the  one  drawback  this  receiver 
does  have  should  be  mentioned:  Limited  fre- 
quency coverage  (3.5  and  7  Mc). 

This  is  rather  serious  for  many  mol)iIe  enthusi- 
asts. However,  by  adding  a  high-frequency  con- 
verter with  output  on  40  or  80  meters,  the  higher 
frequencies  can  also  be  covered  with  the  possible 
partial  loss  of  stability,  bandspread,  and  calibra- 
tion, depending  upon  the  quality  of  the  converter. 

Changes  &  Additions 

The  following  additions  and  modifications  were 
performed  on  the  BC-453-A  to  obtain  our  almost- 
super  mobile  receiver: 

1)  Add  a  crystal-controlled  pentagrid  converter  (6BE6). 
This  is  mounted  on  the  rear  apron  of  the  receiver  originally 
occupied  by  the  dynamotor.  The  Command  receiver  is  used 

*  1825  Cherokee  Drive,  Owensboro,  Ky. 


as  a  tunable  i.f.  amplifier  from  190  to  550  kc.  A  different 
crystal  is  used  for  each  360  kc.  covered.  The  crj'stal  switch 
could  include  a  crystal  for  WWV  or  perhaps  a  local  broad- 
cast frequency. 

2)  Add  one  stage  of  audio  amplification  (6C4)  between 
the  second  detector  and  power  amplifier.  The  stage  is 
mounted  on  a  small  subchassis  underneath  the  receiver. 

3)  .4dd  a.v.c. 

4)  -Add  shunt  noise  limiter  (1N34). 

5)  Add  a.f.  and  r.f.  gain  controls. 

C)  Replace  all  12-volt  tubes  with  their  6-volt  equiva- 
lents. The  12A6  was  replaced  by  a  6V6. 

7)  Rewire  all  heaters  in  parallel. 

8)  Replace  the  antenna  trimmer  capacitor  with  a  unit 
that  is  screwdriver-adjusted  from  the  side.  The  capacitor 
thus  released  was  used  as  a  b.f.o.  pitch  control. 

9)  Add  speaker  and  matcliing  transformer. 

Details 

Let's  take  each  feature  and  study  how  it  can 
be  accomplished. 

The  frequency  stability  is  exceptional  in  this 
unit.  The  crystal-controlled  high-frequency  os- 
cillator, together  with  the  excellent  stability 
found  in  these  receivers,  makes  s.s.b.  reception 
easily  possible  even  while  driving  over  rough 
roads. 

The  BC-453--\  has  an  intermediate  freciuency 
of  85  kc.  and  has  six  tuned  i.f.  circuits.  This  gives 
good  selectivity.  The  selectivity  with  minimum 
coupling  in  each  i.f.   transformer  is  ju.'it  sharp 


A  BC-453-A  with  a  few  revisions  makes  a  good  tun- 
able i.f.  amplifier  for  a  mobile  receiver.  One  is  shown 
here  tucked  under  the  dash.

enough  for  s.s.b.  reception.  (The  coupling  can  be 
varied  by  unscrewing  the  knurled  cover  and  ad- 
justing the  fiber  rod.)  "Up"  position  is  minimum 
coupling.  More  coupling  is  desiral)le  for  a.m.

an  r.f.  gain  control.  This  was  retained  in  the  final 
design  for  s.s.b.,  and  an  audio  control  was  added 
for  normal  a.m.  reception.  In  the  writer's  in- 
stallation, this  receiver  is  independent  of  the 
broadcast  set  except  for  the  speaker.

The  entire  dial  covers  350  kc,  giving  plenty  of

the  80-meter  band.)

on.  The  calibration  will  stay  put  indefinitely.

When  it  was  first  tested  on  a  long-wire  an- 
tenna, this  receiver  had  rather  high  image  re- 
sponse. However,  when  it  was  installed  in  the  car 
and  the  center-loaded  whip  used  as  an  antenna, 
the  images  dropped  to  a  negligible  value.  The 
tuned  antenna  apparently  acts  like  an  additional 
front-end  tuned  circuit. 

The  over-all  dimensions  are  5  by  5^  by  11 
inches  deep,  exclusive  of  speaker  and  power 
supply.  This  is  small  enough  for  under-dash 
mounting  in  almost  any  car. 

The  power  consumption  is  100  ma.  at  250  v.

as  a  Q5-er.  It  was  felt  the  loss  was  more  than 
offset  by  the  addition  of  a  good  mobile  receiver.

QST  for 


For  those  who  do  not  owb  a  BC-453-A,  remember 
that  although  the  price  is  considerably  higher 
than  a  few  years  back,  they  are  still  well  worth 
their  money.  Even  at  today's  prices,  this  modified 
receiver  costs  less  than  the  cheapest  commercial 
converter. 

The  modifications  are  simple  and  require  a 
minimum  of  test  equipment.  The  average  ama- 
teur should  have  no  difficulty  in  this  respect. 

The  6BE6  crystal  converter  is  built  into  a 
homemade  metal  box  that  just  fills  the  space  on 
the  rear  apron  of  the  receiver.  The  simplicity  of 
the  circuit  can  be  seen  in  Fig.  1.  The  only  caution 
the  builder  should  observe  is  to  keep  Li  and  the 
r.f.  chokes  well  separated.  The  controls,  C'l  and 
Si,  are  mounted  on  the  rear  of  the  metal  box. 
The  side  may  be  more  convenient  if  space  is 
available  in  the  reader's  car.  However,  it  is  only 
necessary'  to  adjust  them  when  changing  Ijands. 
so  the  rear  mounting  is  satisfactory. 

The  regular  antenna  post  was  removed  and 
the  hole  plugged.  A  wire  was  soldered  to  th< 
small  mica  condenser  that  was  originally  tied  tn 
the  antenna  post  and  then  run  along  the  inside 
top  of  the  cabinet  to  the  converter  in  the  rear. 
This  will  minimize  stray  pick-up  on  the  i.f.  inter- 
mediate frequency.  It  is  necessary  to  remove  tin 
top  cover  and  variable-condenser  cover  in  order 
to  reach  the  antenna  post.  While  these  covers  are 
removed,  small  holes  can  be  drilled  for  the 
wire  going  to  the  converter.  The  heater  choke 
mounted  just  below  the  d\'namotor  plug  under- 
neath the  chassis  was  removed  and  discarded. 
This  gave  more  working  room.  The  wires  goinjr 
to  the  dynamotor  plug  were  left  as  originally  con- 
nected. The  heater,  B-f-,  and  ground  leads  were 
thus  convenient  to  the  converter  by  soldering  to 
the  banana  plugs. 

The  socket  on  the  rear  of  the  receiver  wa- 
removed  and  the  hole  enlarged  to  1^J^^4  inche.-^. 
This  permitted  the  installation  of  a  conventional 
octal  tube  socket.  Plugs  for  these  sockets  are 
made  by  Amphenol  and  are  available  at  most 
distributors.  The  only  wires  retained  on  this  plug 
were  ground,  heater,  B-|-,  and  audio  output. 
The  others  were  cut  loose  at  their  source  and  re- 
moved. 

The  wires  and  neon  lamp  were  removed  from 
the  antenna  trimmer  condenser:  then  the  stator 
plates  were  connected  to  Pin  6  of  the  6SQ7 
(formerly  a  12SQ7).  The  antenna  trimmer  thus 
became  a  b.f.o.  pitch  control.  A  30-.u^if.  com- 
pression condenser  was  mounted  on  the  side  of 
the  chassis  to  serve  as  a  screwdriver-adjustable 
antenna  trimmer.  There  is  sufficient  gain  in  the 
receiver  for  this  antenna  trimmer  to  be  omitted 
entirely,  if  desired. 

The  small  metal  box  and  condenser  mounted 
on  the  front  panel  should  now  be  removed  to 
make  room  for  the  audio  and  r.f.  gain  controls, 
b.f.o.,  a.v.c,  and  a.n.l.  on-off"  switches.  This 
makes  things  quite  crowded,  and  miniature  com- 
ponents should  be  purchased  for  use  here.  All  the 
wiring  going  to  the  small  metal  box  should  be 
cut  at  its  source  and  removed,  except  the  green 
and   red   wires;   these   are   r.f.    gain   and   b.f.o. 


"off,"  respectively.  The  r.f.  gain  control  is  a 
20,000-ohm  unit,  and  is  connected  to  a  switch 
that  grounds  it  to  turn  the  b.f.o.  on.  The  wiring 
for  the  other  controls  is  shown  in  Fig.  2. 

The  output  transformer  used  in  the  original 
set  was  retained  and  a  2000-ohms-to-voice-coil 
transformer  mounted  at  the  speaker.  This  made 


Lnder  chassis  view  of  the  reworked  BC-4.53-A.  Th^ 
metal  strip  running  across  the  chassis  at  about  the 
center  is  used  to  support  the  6C4  socket. 

a  little  less  modification  work  than  replacing  the 
output  transformer.  Also,  it  made  2000  ohms 
output  impedance  available  for  headphones. 

If  the  receiver  is  used  for  s.s.b.  reception,  for 
the  sake  of  stability  it  would  be  more  desirable  to 
mute  the  receiver  at  the  speaker  rather  than  to 
remove  B-(-  during  transmitting  periods.  This  is 
not  a  necessity  even  for  s.s.b.  reception,  if  the 
builder  wishes  to  use  his  receiver  supply  for  a 
portion  of  the  transmitter.

THREE-WAY  SWITCH  FOR  THE

Oi'EiiATORs  who  employ  the  "Simplest  Modu-

modulator  whenever  the  mode  of  operation  is

output  terminals  are  connected  in  parallel  with 
those  of  the  key,  the  unplugging  motion  is  un-

CONVERTING  FILAMENT  TRANSFORM- 
ERS FOR  PLATE-SUPPLY  USE 

IN  searching  for  miniature  power  transformers 
for  such  low-power  items  as  grid-dip  oscilla- 
tors, etc.,  I  have  found  it  convenient  to  make  my 
own,  using  small  filament  transformers.  Since 
most  of  these  have  the  low-voltage  winding  wound 
on  the  outside,  it  is  a  easy  to  remove  the  few  fila- 
ment turns  to  make  room  for  the  rewinding. 

The  procedure  is  simple.  Count  the  turns  re- 
moved to  determine  the  turns  per  volt  ratio  for 
the  core.  Now  rewind  the  filament  turns  with  a 
smaller  size  wire.  Follow  this  with  the  "high- 
voltage"  winding  using  the  number  of  turns  per 
volt  previously  determined.  The  wire  sizes  should 
be  chosen  so  the  PR  losses  in  the  two  secondaries 


under  load  do  not  exceed  the  rated  PR  loss  for 
the  removed  turns.  This  allowable  loss  is  fairly 
flexible  and  can  be  exceeded  by  50  per  cent  or  so 
for  intermittent  duty  or  where  some  ventilation 
is  present.

IMPROVED  AUDIO  CIRCUIT  FOR  THE 
50-MC.  CD.  UNIT 

ALTHOUGH  the  circuit  to  be  presented  is  in- 
-^  tended  primarily  for  use  with  the  50-Mc. 
unit  described  in  May,  1952,  QST,  it  deserves  con- 
sideration by  anyone  embarked  on  a  speech- 
amplifier  project  designed  with  carbon- micro- 
phone input  in  mind. 

The  new  circuit,  shown  in  Fig.  2,  uses  a  6U8 
triode-pentode  as  a  replacement  for  the  12AT7 
originally  employed  in  the  microphone  input  and 
the  amplifier-clipper  stages  of  the  c.d.  unit.  Not 
only  does  the  revised  arrangement  retain  all  of 
the  desirable  features  discussed  in  the  original 
constructional  article,  but  it  increases  the  gain  of 
the  speech  amplifier  by  10  db.  or  more.  This 
represents  an  improvement  over  the  12AT7 
line-up  and  eliminates  the  need  for  crowding  the 
microphone  so  that  full  modulation  may  be  ob- 
tained.

You  Can't  Beat  F.M. ! 

Advantages  of  "Almost-N.F.M."  for  V.H.F.,  with  Practical 
Application  in  a  48-54  Mc.  Exciter 

BY  DON  H.  GROSS,*  WSQVC 


SOME  of  the  brethren  may  think  me  a  bit  daft 
for  saying  so,  Vjut  for  v.h.f.  voice  work 
nothing  excels  the  right  kind  of  f.m.  Per- 
haps a  few  hardy  souls  will  want  to  venture 
through  the  technical  difficulties  of  single  side- 
band on  frequencies  above  50  Mc,  but  aside 
from  such  a  remarkable  feat,  a.m.  is  definitely 
inferior  to  f.m.,  if  the  latter  is  properly  used. 
Go  ahead  and  laugh,  but  please  read  on. 

The  word  has  gotten  around  prettj^  well  that 
f.m.  eliminates  high-powered  modulators,  and 
that  it  is  far  better  than  a.m.  when  it  comes  to 
TVI  or  BCI.  We  can  also  see  that  the  high  grid 
drive  and  higher  plate  dissipation  and  voltage 
ratings  necessary  for  a.m.  make  it  difficult  when 
we  approach  the  u.h.f.  region.  Then,  too,  a  100 
per  cent  modulated  a.m.  transmitter  in  the 
420-Mc.  band  is  limited  to  12.5  watts  antenna 
power  (since  50  watts  peak  is  the  law),  while  up 
to  50  watts  antenna  power  is  legal  with  f.m. 
But  we  usually  see  a  tendency  to  he  apologetic; 
about  the  communications  value  of  f.m.  This  is 
mainly  because  most  of  our  thinking  since  the 
war  has  been  in  terms  of  stricth'  narrow-band 
f.m.,  where  second-order  sidebands  are  kept  in- 
significant so  that  our  signals  will  occup\'  no 
wider  channels  than  a.m. 

In  order  to  keep  to  true  n.f.m.,  the  modula- 
tion inde.x  must  not  exceed  0.6.  Under  these 
conditions,  as  the  venerable  Handbook  saj's,  "so 
far  as  effectiveness  is  concerned,  a  narrow-band 
f.m.  or  p.m.  transmitter  is  about  equivalent  to 
a  100  per  cent  modulated  a.m.  transmitter  oper- 
ating at  one-fourth  the  carrier  power."  At  this 
rate,  n.f.m.  is  enough  to  discourage  any  self- 
respecting  DX  man.  Add  to  this  the  horrible 
method  of  detecting  f.m.  signals  by  slight  de- 
tuning on  an  a.m.  receiver,  as  nefariously  prac- 
ticed by  most  of  us,  and  anyone  with  a  brain  in 
his  head  would  conclude  that  if  you  want  a 
signal  without  any  vitamins,  if  j'ou  want  your 
voice  dro\\aied  in  a  waterfall  of  noise  and  clob- 
bered with  QRM,  just  use  f.m. 

Whoa  There! 

However,  dear  friends,  w^e  have  been  over- 
looking a  juicy  item.  Above  52.5  Mc.  (and  on 
some  frequencies  below)  we  aren't  confined  to 
the  narrow-band  version  of  f.m.  What  if  we 
crank  the  audio  gain  up  to  give  us  a  modulation 

*1146  Prospect  Road,  Pittsburgh  27,  Pa. 

^  In  most  locations  there  is  not  so  much  v.h.f.  QRM  that 
the  extra  bandwidth  would  matter  much;  and  in  any  case 
heavily-modulated  a.m.  transmitters  in  the  region  above 
144  Mc.  are  already  using  more  space  than  f.m.  with  a 
deviation  ratio  of  1.0. 


index  of  1.0?  Second-order  sidebands  appear, 
but  they  are  still  relatively  weak.^  The  happy 
part  is  what  happens  to  the  first-order  sidebands. 
Now  they  have  some  real  zip.  Put  this  signal 
through  an  i.f.  ampUfier  of  6  or  7  kc.  bandwidth, 


The  \\  3Q\  C  f.m.  exciter  is  a  compact  package.  At

detect  it  with  a  good  ratio  detector  or  discrimi- 
nator-foUowing-a-limiter,  and  presto  —  f.m. 
comes  into  its  own! 

Rummage  through  the  old  QSTs  published 
just  before  the  war  and  there  you  will  see  the  ^ 
beginnings  of  a  development  in  amateur  f.m. 
that  was  nipped  in  the  bud  at  Pearl  Harbor. 
Look,  for  instance,  at  that  fascinating  article 
by  ^Murray  Crosbj^  on  "Bandwidth  and  Reada- 
bilit}'  in  Frequency  Modulation,"  page  26  of 
March,  1941,  QST.  There  we  see  that  for  maxi- 
mum readability  of  weak  signals  the  deviation 
ratio  should  be  1.0,  and  that  such  an  f.m.  signal 
is  always  more  readable  than  a.m.  In  fact,  at 
some  weak  signal  levels  this  "almost-n.f.m." 
signal  is  as  readable  as  an  equivalent  100  per 
cent  modulated  a.m.  signal  of  four  times  the 
power.  Thus  the  tables  are  turned.  If  it  is  trans- 
mitted and  received  properly,  you  can't  beat  f.m.

How  To  Get  Good  F.M.  Above  50  Mc. 

Reactance-tube  modulation  of  a  self-excited 
oscillator  just  isn't  stable  enough  for  good 
narrow-band  work  on  v.h.f.  WIVLII  has  the 
right  idea  in  his  phase-modulation  exciter.-  A 
crystal  oscillator  provides  the  necessary  sta- 
bility. Reactance  modulation  of  a  tank  circuit 
provides  phase  modulation.  The  only  difference 
between  a  p.m.  and  an  f.m.  signal  is  that  with 
p.m.  the  f  requeue  J'  deviation  rises  in  propor- 
tion to  the  modulating  audio  frequency  (assum- 
ing that  the  amplitude  of  the  modulating  wave 
is  held  constant),  while  with  f.m.  the  deviation 
is  the  same  for  all  audio  frequencies.  So  the 
secret  of  turning  p.m.  into  f.m.  is  to  make  the 
output  of  the  speech  amplifier  vary  in  inverse 
proportion  to  the  audio  frequency.  Only  the  r.f. 
section  of  an  exciter  is  to  be  described  here,  but 
the  speech  amplifier  that  is  used  with  it  ends  up 
with  a  6SJ7  having  an  effective  load  resistance 
of  50K.  A  0.006-juf.  condenser  across  this  load 
gives  the  proper  inverse  frequency  response.  A 
clipper-filter  circuit  is  also  used,  and  this  is  most 
desirable. 

A  Phase-Modulation  Exciter 

The  exciter  shown  here  is  a  straightforward, 
highly  stable  affair  with  sufficient  output  at 
48-54  Mc.  to  drive  an  832  tripler  to  144  Mc.  It 
uses  single-control  tuning,  for  compactness  and 
simplicity  of  operation.  Crystals  for  8  to  9  Mc. 
plug  in  the  front.  Shielding,  short  wiring,  and 
voltage  regulation  of  the  oscillator  screen  all 
serve  to  give  excellent  isolation  of  the  grid- 
screen  oscillator  circuit  from  the  phase-modu- 
lated plate  tank,  even  though  both  operate  at 
the  same  frequency. 

The  6AG7  reactance  modulator  has  enough 
gain  and  plate-current  capacity  to  provide  ade- 
quate deviation  at  50  Mc,  and  more  than  enough 
for  multiplication  to  higher  frequencies.  About 
two  volts  of  audio  (at  normal  voice  frequencies) 
gives  proper  deviation  for  the  144-Mc.  band. 
Some   care   has   been   taken  in   by-passing  the 

2  Southworth,  "A  Phase-Modulation  Exciter  for  tiie 
V.H.F.  Man,"  QST,  Adjust,  1954. 


screen  and  cathode  of  the  modulator,  as  well  as 
in  adjusting  the  grid  to  ground  capacity,  in 
order  to  eliminate  v.h.f.  parasitic  oscillations. 

The  plate  tank  tuning  range  is  determined  by 
Li,  Ci,  and  other  circuit  capacities  across  Li. 
Tracking  is  accomplished  through  adjustment  of 
L2,  C4,  L3,  and  C5.  TVI  is  prevented  by  proper 
shielding  and  by-passing.  An  electrostatically 
shielded  output  link  helps  further  in  coupling 
out  only  the  desired  frequency.  All  tubes  have 
protective  cathode  bias.  Power  supply  require- 
ments are  300  volts  at  about  125  ma.,  and  6.3 
volts  a.c.  at  2.7  amp. 

Construction 

The  exciter  is  built  in  a  3  X  4  X  5-inch  alu- 
minum box  (Bud  CU-3005  Minibox).  Holes  are 
drilled  in  the  cover  opposite  the  mica  trimmers 
Ci  and  Cf,  to  allow  adjustment  after  assembly. 
They  may  then  be  covered  with  adhesive  tape. 

The  crystal  was  at  first  mounted  in  the  center, 
but  had  to  be  moved  closer  to  the  oscillator 
tube  to  achieve  proper  isolation  from  the  rest  of 
the  circuit.  A  small  aluminum  shield  partition  is 
placed  between  the  6AG7  oscillator  and  the 
tuning  condenser;  the  cathode  by-pass  condenser 
is  placed  so  as  to  shield  the  plate  contact  on  the 
tube  socket  from  the  grid;  and  RFC\  is  small, 
with  a  short  lead  to  the  screen  grid.  All  these 
precautions  carefully  isolate  the  crystal  circuit, 
to  achieve  maximum  stability. 

A  small-diameter  octal  socket  allows  the 
tripler  tube  to  be  mounted  in  its  limited  space. 
Don't  dope  the  tripler  plate  coil  until  its  circuit 
is  aligned.  Note  that  the  center  section  of  the 
tuning  condenser  is  used  for  the  oscillator  plate; 
the  front  section  for  the  tripler  plate;  and  the 
rear  section  for  the  doubler  plate.  Insulated 
'phone  tip  jacks  are  used  for  grid-circuit  meter- 
ing. The  modulator  screen  by-pass  in  the  photo- 
graphed unit  is  a  mica  condenser;  a  disk  ceramic 
condenser  is  specified  because  it  is  cheaper. 

Adjustment  and  Operation 

The  initial  tune-up  procedure  is  as  follows: 

1)  Put  the  bottom  cover  on,  but  without  its 
screws.  Set  d  to  minimum  capacity.  Plug  in  the 
highest  frequency  crystal  to  be  used,  and  con- 
nect a  high-impedance  voltmeter  between  J 3 
and  ground.  Adjust  the  main  tuning  condenser 
for  maximum  negative  voltage.  This  should  be 
aliout  130  to  150  volts. 

2)  Change  the  meter  to  Ji,  and  tune  C4  for 
maximum  negative  voltage,  which  should  be 
around  70  to  90  volts.

iiig  the  erystal  circuit.  Two  phono-type  jacks  are  for 
audio  input  and  r.f.  output.  Tip  jacks  are  for  measuring 
tripler  and  douhler  grid  voltages.

3)  Plug  in  the  lowest-irequeiKy  crystal  and 
tune  the  ganged  condenser  for  niaxinium  volt- 
age at  /s;. 

4)  Adjust  the  slug  in  L2  lor  maximum  volt- 
age at  J4. 

5)  Repeat  Steps  1  through  -4  until  no  further 
adjustments  are  necessary.  The  spacing  of  the 
turns  of  L2  may  have  to  be  changed  if  the  slug 
does  not  give  enough  tuning  range  in  the  right 
direction.  Remember  that  minimum  inductance 
is  with  the  slug  all  the  way  in.  Inductance  also 
decreases  as  the  turns  are  spread  apart.  ^Vhen 
you  are  sure  the  slug  will  properly  align  L2, 
dope  the  turns  in  place. 

6)  Now  for  the  output  tank.  With  the  highest 
frequency  crystal,  tune  the  ganged  condenser  for 
maximum  voltage  at  J3.  Then  tune  C5  for 
maximum  output. 

7)  Try  the  ^oti;esi-frequency  crystal.  Tune  the 
ganged  condenser  for  a  maximum  voltage  at  J3 
again.  Note  which  direction,  if  any,  C^  must  be 
tuned  for  maximum  output.  If  you  had  to  in- 
crease its  capacity  by  tightening  it,  squeeze  the 
turns  of  Ls  together  a  bit;  if  you  decreased  C5, 
spread  L3  a  little.  You  will  have  to  remove  the 
bottom  cover  to  do  this;  be  sure  to  replace  it 
before  checking  alignment. 

8)  Repeat  Steps  6  and  7  until  no  change  in 
C5  is  necessary  for  Step  7. 


The  exciter  is  now  aligned.  Screw  on  the 
bottom  cover.  After  this,  all  you  do  is  plug  in 
the  desired  crystal  and  tune  the  knob  for  maxi- 
mum output. 

Frequency  deviation  is  adjusted  by  controll- 
ing the  output  of  your  speech  ampUfier.  The 
optimum  adjustment  is  that  which  gives  maxi- 
mum output  without  appreciable  distortion,  at 
a  moderate  signal  level,  in  a  receiver  with  a  6- 
or  7-kc.  i.f.  bandwidth,  equipped  with  a  ratio 
detector  or  limiter-and-discriminator.  The  n.f.m. 
adapters  advertised  for  a  number  of  the  stand- 
ard commercial  ham  receivers  fill  the  bill  per- 
fectly.

The  5100  Transmitter  and  51SB 
Single-Sideband  Generator 


ANY  amateur  interested  in  a  complete  'phone/ 
/%  c.w.  transmitter  in  the  150-watt  class,  to 
■^  -*-  which  he  can  later  add  s.s.b.  with  a  mini- 
mum of  effort,  will  do  well  to  consider  the  new 
Barker  &  Williamson  5100  Transmitter  and  its 
companion  unit,  the  51  SB  Single-Sideband  Gen- 
erator. When  the  two  units  are  tied  together, 
switching  to  c.w.,  a.m.  or  s.s.b.,  or  any  amateur 
band,  80  through  10  meters,  is  simple  and  quick. 

The  5100  Transmitter 

Designed  for  table-top  operation,  the  5100 
is  22  inches  wide,  llH  inches  high  and  14% 
inches  deep.  It  weighs  83  pounds.  The  r.f.  line-up 
consists  of  a  6BJ6  VFO  (in  the  160-meter  band) 
followed  by  two  6BJ6  buffer  stages.  The  second 
buffer  stage  is  grid-block  keyed,  and  serves  as  the 
crystal  oscillator  when  crystal-controlled  opera- 
tion is  demanded.  The  frequency-multiplication 
section  of  the  transmitter  uses  up  to  four  6AQ5s, 
depending  upon  the  multiplication  requirement, 
and  this  entire  section  is  broadbanded  and  conse- 
quentlj^  requires  no  tuning  in  operation.  The 
output  stage  uses  two  6146s  in  parallel,  with  a 
pi-network  output  circuit.  A  small  variable  con- 
denser across  the  grid  circuit  of  the  output  stage 
trims  the  circuit  and  serves  as  an  excitation 
control.  Recommended  operation  of  the  6146s 
permits  a  power  input  of  135  watts  on  'phone  and 
150  watts  on  c.w. 

The  audio  section  of  the  5100  uses  a  6U8 
triode-pentode    speech    amphfier,    6AQ5    trans- 


former-coupled driver,  and  a  pair  of  6146s  for 
modulators. 

A  low-pass  filter  is  included  in  the  transmitter, 
which  makes  it  mandatory  that  the  transmitter 
work  into  the  same  load  resistance  (75  ohms)  on 
all  bands.  All  leads  entering  or  leaving  the  pack- 
age are  filtered,  as  a  further  precaution  against 
TVI.  The  manufacturer  states  that  the  low-pass 
filter  has  a  minimum  attenuation  of  85  db.  over 
the  TV  range,  with  over  100  db.  at  Channel  2. 
The  instruction  book  devotes  two  pages  to  sug- 
gested antenna  systems,  apparently  to  allay  any 
fears  that  working  a  transmitter  into  a  given  load 
resistance  may  represent  an  insurmountable 
obstacle.  Actually,  of  course,  it  is  the  only  way  a 
transmitter  with  a  built-in  low-pass  filter  of  this 
type  can  be  operated,  and  it  has  the  advantage 
that  the  pi-network  circuit  can  be  properly  de- 
signed for  the  same  Q  on  all  bands. 

Two  power  supplies  are  included  in  the  trans- 
mitter, a  high-voltage  one  for  the  6146s  and  a 
low-voltage  one  for  the  other  stages  and  for  bias 
voltages.  A  pair  of  5R4GYs  is  used  in  the  heavy 
supply  and  a  5V4G  handles  the  job  in  the  other 
supply.  Two  VR  tubes  take  care  of  the  regulation 
problems. 

One  bit  of  unusual  circuitry  can  be  found  in  the 
frequency-multiplier  section  where,  for  d.c, 
one  pair  of  6AQ5s  is  connected  in  series  with  the 
other  pair  of  6AQ5s  across  the  600-volt  high- 
voltage  supply.  This  is  a  good  way  to  utilize  a 
power  supply  to  best  advantage,  but  it  is  the 


A  top  view  of  the  5100  Trans- 
mitter shows  how  the  construc- 
tion has  been  broken  down  into 
subassemblies.  The  r.f.  output 
section  can  be  seen  at  the  left 
near  the  panel,  while  the  6146 
modulators  are  at  the  right  near 
the  panel.  The  four  tubes  in  the 
r.f.  multiplier  section  are  mounted

of  commercial  gear.  A  similar  dodge 
was  used  a  few  j-ears  ago  in  a  mo- 
Inle  rig  described  in  QST} 

For  c.w.  operation  the  screens  of 
the  output  6146s  get  their  power 
from   the  low-voltage   supply;   on 
'phone  the  screens  are  fed  from  the  high- voltage 
supply    through    a    dropping    resistor,    so    that 
modulation  is  applied  to  both  plates  and  screens. 
For  tune-up  on  either  'phone  or  c.w.,  the  voltage

of  the  big  supply  is  reduced  by  dropping  the 
line  voltage  through  a  resistor. 

The  owner  of  a  5100  doesn't  have  to  give  up 
the  unit  when  going  to  higher  power  — •  terminals

to  75  watts)  to  drive  a  larger  modulator.

'  Sideband  selection  is  obtained  by  reversing  the  polarity  of  one  of  the  audio  channels.  One  cathode  of  each  balanced 
modulator  is  opened  for  carrier  unbalance  when  tuning  the  following  r.f.  stages.

point,  the  front  panel  carries  the  VFO  knob  (a 
large  one),  bandswitch,  meter  switch  for  measur- 
ing grid  and  plate  current  of  the  output  stage 
and  plate  current  of  the  modulator,  a  CW-VFO- 
PH  switch  for  selecting  the  mode  and  for  spotting 
frequency,  and  A.C.,  Tune-Operate  and  Plate 
switches.  Once  the  band  is  selected,  the  operator 
has  only  to  set  the  VFO  and  adjust  the  plate 
tuning  and  loading  controls  of  the  output  stage, 
touching  up  the  excitation  control  also,  if  neces- 
sary. The  VFO  frequency  can  be  easily  read  on 
the  slide-rule  type  scale. 

The  52 SB  Single- Sideband  Generator 

The  companion  s.s.b.  generator  for  the  5100  is 
a  small  10  X  Uli  X  145i-inch  package  that 
is  placed  to  the  right  of  the  transmitter  and  tied 
in  electricall}^  with  interconnecting  cables  and 
mechanically  with  bolts.  Once  it  is  properly  con- 
nected to  the  5100,  it  is  a  relatively  simple  matter 
to  change  from  s.s.b.  to  a.m.  or  c.w.  and  back 
again. 

The  51SB  takes  r.f.  at  the  output  frequency  from 
the  5100  multiplier  section  and  generates  s.s.b. 
at  the  output  frequency  through  audio  and  r.f. 
phase  shifts.  Fig.  1  shows  a  simplified  schematic  of 
the  two  balanced  modulators.  The  audio  section 
of  the  51  SB  uses  IJ2  sections  of  12AT7s  in  cas- 
cade before  the  audio  is  introduced  into  the  audio 
phase-shift  network.  A  3500-cycle  cut-off  low-pass 
filter  ahead  of  the  network  protects  the  network 
from  audio  frequencies  beyond  its  range.  From 
here  the  signal  is  amplified  and  then  trans- 
former-coupled into  the  two  12 ATT  balanced 
modulators.  The  voice-controlled  break-in  and 
antitrip  (for  loudspeaker  operation)  circuits  use 
12AT7s  and  a  6AL5.  The  output  of  the  balanced 
modulator  is  amplified  through  a  6CL6-6V6 
chain  to  build  up  the  amplitude  to  the  point 
where  it  is  sufficient  to  drive  the  pair  of  6146s  in 
the  5100  transmitter.  Two  tuning  controls  are 
included  in  the  s.s.b.  generator:  the  balanced- 
modulator  output  circuit  and  a  ganged  control 
for  the  6CL6  and  6V6  plate  circuits.  The  r.f. 
phase-shift  networks  are  broadbanded  and  do  not 
require  adjustment.  Consequently,  the  tune-up 
procedure  of  the  51SB  is  quite  similar  to  the 
tune-up  of  any  series  of  r.f.  stages,  and  the  opera- 
tor does  not  have  to  be  familiar  with  how  s.s.b. 
works  to  put  the  rig  on  the  air.  A  switched  meter 
in  the  unit  monitors  the  grid  current  of  the  6146s 
and,  by  using  a  pair  of  germanium  diodes,  the 
out  j)ut  of  the  6VG  driver.  The  r.f.  output  position 


is  used  to  set  up  the  two  carrier-balance  panel 
controls. 

The  voice-operated  control  circuit  closes  a 
three-pole  double-throw  relay  that  provides  a 
keying  circuit  for  the  transmitter,  an  antenna 
relay  control  circuit,  and  a  receiver-silencing 
channel.  Adjustable  voice-control  threshold  and 
hold-in  controls  are  available  inside  the  unit,  as  is 
the  antitrip  sensitivity  control.  The  unit  can  be 
used  "push-to-talk"  from  a  switch  on  the  micro- 
phone or  with  full  voice-controlled  break-in,  as 
desired. 

Most  of  the  panel  controls  have  been  men- 
tioned, but  in  addition  there  is  a  carrier-unbal- 
ance switch  (for  tune-up),  upper  or  lower  side- 
band selector  switch,  bandswitch,  tune-operate 
switch,  and  an  audio  gain  control.  In  operation 
it  is  necessary,  of  course,  to  make  sure  that  the 
bands  witches  on  the  51  SB  and  the  5100  are  set  to 
the  same  band.  A  minor  inconvenience,  but  noth- 
ing to  worry  anyone  who  has  gone  this  far  in 
equipping  a  complete  station,  is  the  necessity  for 
changing  microphone  from  unit  to  unit  when 
going  from  s.s.b.  to  a  m.,  but  this  could  be  solved 
by  using  two  microphones  or  a  shielded  switch. 

All  of  the  power  leads  leaving  or  entering  the 
51  SB  are  filtered,  in  keeping  with  the  TVI  pre- 
cautions in  the  5100.  A  5Y3G  in  the  power  supply 
handles  the  plate-power  requirements  of  the 
exciter. 

Genei'al 

In  both  the  5100  and  51  SB,  considerable  use 
has  been  made  of  subassembly  type  construction. 
This  is  illustrated  in  the  accompanying  photo- 
graphs. The  subassemblies  are  a  production  ex- 
pedient, of  course,  but  they  also  contribute  to 
shielding  within  the  unit. 

Instruction  books  for  both  units  are  careful  to 
give  step-by-step  instructions  for  all  operations, 
and  anyone  who  takes  the  time  to  read  them 
should  have  no  trouble. 

Of  special  interest  to  home  constructors  of 
s.s.b.  gear  is  the  little  audio  phase-shift  network 
used  in  the  51  SB.  It  is  similar  to  others  on  the 
market  in  that  it  provides  a  90-degree  shift  over 
the  300-3000-cycIe  range,  but  this  one  is  com- 
pletely enclosed  in  a  metal-tube  envelope  of  the 
size  used  for  a  6J5.  Thus,  plug-in  convenience 
and  good  shielding  are  provided  in  a  very  small 
package.  This  unit,  the  B  &  W  Model  350,  is 
marketed  separately.

and  reflected  power,  as  was  the  case  with  the 
original  MicroMatch.  The  Models  261  and  263 
each  consist  of  essentially  two  MicroMatch

the  outgoing  voltage  continuously  while  the  other 
monitors  the  reflected  voltage.

line  balances  out  the  forward  voltage  and  re- 
sponds to  the  reflected  voltage,  which  is  rectified 
by  CRi.  The  voltmeter,  a  0-200  microammeter 
with  appropriate  series  resistors  for  several  usable 
voltage  ranges,  can  be  connected  to  either  circuit 
liv  means  of  the  single-pole  single-throw  switch.

The  basic  circuit  by  which  this  is  accompUshed 
is  shown  in  Fig.  1.  /?i  is  the  series  resistance  of  the 
original  MicroMatch  circuit.  CRi  is  the  voltmeter 
rectifier  for  reading  the  forward  voltage.  The

Internal  construction  of  the  coupler 
unit  is  shown  by  the  view  with  the  cover 
removed,  at  the  left.  The  unit  comes 
furnished  with  protective  caps  for  the 
coax  connectors  as  shown  at  the  right. 
The  units  are  designed  for  use  with  52- 
ohm  lines. 


Both  models  consist  of  a  "coupler  unit"  and 
an  "indicator  unit."  The  former  contains  the 
actual  bridge  and  the  latter  the  voltmeter  and 
multipliers.  The  coupler  units  are  identical  in 
both  models  except  for  the  Une  connectors;  regu- 
lar coax  fittings  are  used  on  the  261  and  "N" 
tjT)e  fittings  on  the  263.  The  indicator  unit  for 
the  Model  261  (it  has  a  separate  number,  262) 
uses  a  variable  resistor  as  a  multiplier,  with  cali- 
bration points  for  10,  100  and  1000  watts  full- 
scale  reading  marked  on  the  resistor  scale.  The 
Model  263  indicator  uses  an  individual  factory- 
adjusted  variable  resistor  for  each  of  the  same 
three  ranges  and  selects  them  with  a  switch.  The 
meter  calibration  is  in  watts  and  is  the  same  on 
both  indicators  —  0-10,  0-100,  and  0-1000  — 
and  the  same  type  of  meter  is  used  in  both.  The 
actual  power  delivered  to  a  load  is  found  by  tak- 
ing the  difference  between  the  forward  and  re- 
flected power  readings.  The  voltage  standing- 
wave  ratio  is  found  by  taking  the  ratio  of  the 
forward  to  reflected  power  and  reading  the  cor- 
responding v.s.w.r.  in  instruction  book  chart. 

Either  coupler  can  be  left  in  the  transmission 
line  continuously,  provided  the  power  does  not 
exceed  one  kilowatt  with  an  s.w.r.  of  1  to  1.  The 
bridges  are  designed  for  52-ohm  lines.  ^

the  whole  stor}'  of  its  performance,  as  the  sources 
of  error  are  seldom  obvious.  The  accuracy  of  a 
bridge  of  this  type  is  almost  entirely  determined 
by  the  selection  of  components  and  the  method  of 
construction.  The  inside  view  of  one  of  the  coupler 
units  shows  the  special  constructional  arrange- 
ment adopted  to  maintain  accuracy  over  the 
frequency  range  from  3  to  225  Mc,  and  to  pre- 


vent the  coupler  from  introducing  an  impedance 
"bump"  in  the  line.  The  insertion  loss  is  stated 
to  be  less  than  0.1  db. 

Couplers  and  indicators  can  be  obtained 
separatelJ^  The  instruction  book  with  the  coupler 
contains  circuit  information  for  home  construc- 
tion of  an  indicator  unit,  in  case  only  the  coupler 
is  purchased.  —  G.  G. 


The  RME-100  Speech  Clipper 


THE  advantage  of  speech  clipping  should  be 
quite  well  known  by  this  time.  Modulation 
percentage  is  limited  by  the  amplitude  of  the 
modulating  wave  form,  rather  than  by  average 
modulating  power.  The  speech  clipper  increases 
the  ratio  of  average  modulating  power  to  peak 
amplitude  by  clipping  the  peaks  of  the  wave 
form.  This  increases  the  average  percentage  of 
modulation,  improving  the  intelligibility  without 
increasing  the  transmitter  power.  Since  clipping 
introduces  distortion  in  the  form  of  harmonics,  a 
filter  for  the  harmonics  follows  the  clipper. 

The  RME-lOO  consists  of  a  two-stage  pream- 
plifier, using  a  6SC7  dual  triode,  followed  by  a 
6H6  clipper  and  a  harmonic  filter.  Power  supply 
is  included  in  a  unit  measuring  5  by  6  by  7  inches. 
The  circuit  is  shown  in  Fig.  1.  The  unit  is 
designed  to  be  inserted  between  the  microphone 
and  the  first  stage  of  the  speech  amplifier,  and  a 
switch  is  provided  for  cutting  the  unit  in  or  out 
of  the  circuit.  The  gain  is  limited  to  about  6  db. 
at  the  maximum  clipping  level  so  that  a  mini- 
mum of  readjustment  of  the  speech-amplifier 
gain  control  is  necessary  when  the  clipper  is 
switched  in  or  out. 

About  15  millivolts  of  audio  is  required  to  pro- 
duce a  full  24  db.  of  clipping.  This  is  usually 
obtained  from  a  crystal  or  dynamic  microphone 
when  talking  normally  with  the  microphone  at  a 
distance  of  about  3  inches.  The  clipping  control

The  P-500  Power  Amplifier 


THE  Lakeshore  Industries  P-500  power  ampli- 
fier is  another  in  the  current  crop  of  power 
amplifiers  designed  primarily  to  boost  the 
power  level  of  a  single- sideband  signal.  It  uses 
a  pair  of  5514  triodes  in  push-pull,  with  multi- 
band  tuners^  in  the  grid  and  plate  circuits  to 
cover  the  amateur  bands  from  80  to  10  meters. 
As  a  consequence,  there  is  no  bandswitch  of  any 
kind,  and  the  panel  has  two  dials,  for  the  grid 
and  plate  tuners,  and  a  knob  for  controlling  the 


The  Lakeshore  Industries  P- 
500  power  amplifier  uses  a  pair  of 
5514  triodes  mounted  horizon- 
tally. Multiband  tuners  hoth  in 
grid  and  plate  circuits  eliminate 
the  need  for  a  bandswitch.  Nor- 
mally, the  grid-circuit  compart- 
ment is  covered  by  an  aluminum 
plate. 

The  construction  of  this  unit  is 
interesting  in  that  no  normal 
"chassis"  is  used.  The  grid  com- 
partment is  a  box  within  the 
larger  box  that  makes  up  the 
unit.  A  cane-metal  top  covers  the 
box  shown  here,  and  the  whole  unit 
then   fits  into  a  painted  cabinet. 


grid-circuit  coupling.  A  0-500  milliammeter  on 
the  panel  is  connected  in  the  filament  return  to 
ground  and  reads  the  total  of  grid  and  plate 
currents. 

The  line  cord  coming  out  the  rear  of  the 
cabinet  connects  to  the  filament  transformer  — 
terminals   for   connecting   to   the   plate   supply

and  the  bias  supply  are  at  the  rear  of  the  chassis, 
as  are  the  connectors  for  r.f.  input  and  output. 
The  bias  supply  to  be  used  will,  of  course,  depend 
upon  the  plate  voltage  available.  The  factory 
recommendation  is  a  plate  supply  of  1000  to 
1250  volts.  The  output  terminals  provide  for 
connection  to  either  balanced  or  coaxial  line. 

Circuitwise,  the  P-500  is  similar  to  any  other 
neutralized  push-pull  triode  amplifier,  except 
perhaps  for  the  use  of  tapped  parasitic  r.f.  chokes 


in  the  plate  leads  and  56-ohm  resistors  in  series 
with  the  neutralizing  condensers.  (A  number  of 
triode  amplifiers  used  as  linears  seem  to  require 
these  resistors;  e.g.,  the  811- A  amplifier  described 
in  March,  1951,  QST.)  Loaded  parasitic- sup- 
pression chokes  are  also  used  in  the  grid  circuit, 
together  with  a  2700-ohm  swamping  resistor  for 
better  driver  loading.

Operational  Readiness  Vital 
to  Successful  Disaster  Work 

Operational  readiness  is  the  key  to  success  in 
disaster  communications  service  and  for  public 
service  operations  where  the  time  element  is 
important.  Two  recent  examples  of  alertness 
and  operational  readiness  follow: 

In  the  first  instance,  an  earthquake  rocked 
the  Fortuna,  Calif.,  area  at  1956Z  hours  on  22 
December  1954,  causing  extensive  property  dam- 
age. T.  V.  Conroy,  A6GQY,  of  Fortuna  immedi- 
ately established  an  emergencj^  link  with  Sixth 
Army  Headquarters  and  with  the  Civil  Defense 


Coordinator  for  Region  One,  Col.  T.  Monroe. 
The  circuit  was  in  operation  at  2004Z,  just  eight 
minutes  after  the  initial  shock.  Communication 
was  maintained  continuously  until  0215Z  on  the 
23rd  when  it  was  officially  determined  that 
services  of  the  Sixth  Army  Engineers  wofild 
not  be  required.  A6GQY  reports  that  circuit 
discipline  on  4020  and  4025  kc.  was  excellent. 

Five  days  earlier,  on  17  December  1951, 
a  radio  link  was  set  up  between  Clovis  (N.M.) 
Air  Force  Base  and  Goose  Bay,  Labrador,  to 
provide  medical  information  concerning  an  air- 
man who  had  been  bitten  by  a  rabid  dog.  Sta- 
tions A5HJF  and  AA5WSP  were  instrumental  in 
this  operation.  A  relay  was  established  between 
Goose  Bay  Dispensary  and  the  Clovis  Air  Force 
Base  Hospital  so  that  additional  information 
could  be  transmitted.  The  Air  Force  MARS 
emergency  frequency  of  3838  kc.  was  used.

The  hams  in  tlxis  area  did  a  wonderful  job  of  collecting 
pledges  during  the  38-hour  telethon  for  the  benefit  of  Cere- 
bral Palsy  victims.  The  entire  St.  Louis,  East  St.  Louis, 
Granite  City,  Madison,  Venice,  Alton  area  was  blanketed 
by  mobile  operators  who  gathered  in  the  gold  as  it  was 
pledged  via  land  line  to  several  hundred  operators  at  the  Keil 
Auditorium  Cerebral  Palsy  headquarters.  About  $50,000 
was  pledged  and  picked  up  by  the  mobile  hams.  W0QDF 
was  the  spark  plug  who  mustered  the  hams  into  the  drive 
and  created  an  efficient  mobile  pick-up  network,  but  just 
about  every  operator  in  the  area  deserves  credit  for  having 
given  of  his  time  to  make  the  drive  the  success  that  it  was.

21-MC.  VIOLATIONS

Several  times  wliile  operating  21-Mc.  'phone  there  have 
been  more  W  stations  in  the  foreign  'phone  section  than 
there  has  been  DX. 

This  may  be  attributable  to  the  fact  that  the  band  is 
fairly  new  or  that  the  majority  of  receivers  do  not  have  too 
accurate  frequency  markings,  or  none  at  all  for  the  band. 
Of  course,  there  is  also  the  possibility  that  some  Ws  do  not 
know  the  limitations  of  the  American  'phone  band  on  21 
Mc.  So,  I  would  recommend  that  in  the  near  future  a  listing 
be  made  of  21  Mc.  showing  the  frequency  restrictions  and 
pointing  out  the  band  limits.  I  hope  this  note  will  possibly 
save  someone  from  receiving  a  "  pink  "  ticket  for  out-of-band 
operation.

NOVICE  CHANGE

I  should  like  to  hear  some  discussion  on  proposing  a 
change  in  Novice  regulations  to  extend  the  term  to  "one 
year  or  to  the  13th  birthday."  I  think  the  younger  guys  and

FOR  THE  BIRDS 

Ilobbs,  N.  Mex. 
Editor,  QST: 

I  think  it's  about  time  I  had  my  say  about  one  of  my  pet 
gripes:  c.w.  in  the  'phone  bands.  This  is  for  the  birds!  I'll 
admit  c.w.  was  here  first,  and  it  undoubtedly  has  its  place 
in  ham  radio,  but  I  personally  think  it  is  a  thing  of  the  past. 

I  think  the  'phone  bands  should  be  reserved  for  'phone 
operation.  After  all,  if  c.w.  operators  are  going  to  be  allowed 
to  have  large  portions  of  each  band  set  aside  for  their  ex- 
clusive use,  with  big  keep-off  signs  posted  to  'phone  men,  it 
is  only  fair  tliat  'phone  men  should  enjoy  the  same  rights. 


Any  night  you  can  hear  c.w.  and  teletype  all  over  the 
75-meter  'phone  band,  while  there  are  wide-open  spots  all 
over  the  c.w.  portion. 

I  was  enticed  into  ham  radio  by  the  reduced  code-speed 
requirements  of  the  Novice  ticket,  and  now  I  am  being 
booted  out  by  the  c.w.  and  Sloppy  Splatter-Band  operators. 
Don't  misimderstand  me;  I  like  ham  radio.  I've  learned 
enough  radio  since  going  on  the  air  as  an  amateur  to  pass 
my  commercial  'phone  exam. 

All  I'm  asking  is  fair  treatment  for  all  hams.  If  a  man 
wants  to  operate  c.w.,  that's  his  business,  but  if  the  FCC  is 
going  to  let  him  have  his  run  of  'phone  bands,  then  let  the 
'plione  men  into  the  c.w.  bands.

IT'S  FOR  THEM 

326  So.  Walnut  Street 
Cookeville,  Tenn. 
Editor,  QST: 

There  has  been  quite  a  big  blow  for  the  past  few  years 
about  putting  both  c.w.  and  s.s.b.  off  the  air.  Or  at  least  off 
the  75-meter  'phone  band.  Both  of  these  modes  of  transmis- 
sion seem  to  bother  the  a.m.  'phone  men.  1  think  the  prin- 
cipal reason  for  this  is  the  fact  that  most  of  the  a.m.  'phone 
men  have  forgotten  what  their  b.f.o.'s  are  used  for  ...  if 
they  ever  knew.  Anyway,  they  couldn't  read  c.w. 

What  I  would  like  to  know  is  this:  Would  it  be  possible 
to  put  a.m.  'phone  (the  kind  with  a  carrier  and  two  side- 
bands) off  the  air  completely? 

There  is  a  good  argument  for  this  action.  Both  c.w.  and 
s.s.b.  rigs  are  much  more  economical  to  build  and  operate. 
They  are  both  less  likely  to  cause  TVI.  They  both  can  be 
operated  with  greater  spectrum  economy. 

In  a  15-kc.  segment,  only  one  a.m.  'phone  station  can  be 
operated  without  interference.  (I  have  heard  several  of  the 
kilowatt-give-or-take-a-hundred-watts  rigs  around  here  that 
are  much  broader  than  15  kc.)  But  in  the  same  l£-kc.  seg- 
ment, two  s.s.b.  stations  and  ten  c.w.  stations  may  be  oper- 
ated without  cross-interference.  This  is  figuring  the  s.s.b. 
stations  as  being  3000  cycles  wide  and  the  c.w.  stations 
operating  within  900  cycles  of  each  other,  which  is  entirely 
practicable. 

I  would  like  to  hear  from  other  hams  and  get  their  opin- 
ions on  the  proposal  of  outlawing  a.m.  'phone.  The  time  has 
come  that  we  cannot  waste  any  parts  of  our  crowded  ama- 
teur bands!

Editor,  QST: 

A  year  or  so  ago,  when  s.s.b.  began  to  be  an  issue,  I  was 
violently  and  openly  opposed  to  any  part  of  it.  However, 
this  past  summer  I  had  plenty  of  time  to  do  some  considering 
of  the  issue.  After  careful  study  and  consideration  of  the 
subject,  I  had  to  admit  that  perhaps  some  of  my  personal 
and  "technical"  opinions  didn't  add  up  to  the  right  answer 
—  that  is,  what  I  wanted  them  to  add  up  to.  I  went  so  far 
as  to  visit  a  s.s.b.  station,  and  talked  over  the  rig.  It  made 
sense.  After  some  more  study  I  bought  an  exciter,  built  an 
amplifier,  with  the  purpose  in  mind  of  finding  out  for  myself 
what  s.s.b.  had  and  didn't  have  to  offer. 

I  found  out  some  of  the  following  things.  The  s.s.b.  group 
of  operators,  by  the  somewhat  more  technical  nature  of 
their  equipment,  are  trying  to  do  a  good  job,  and  are  forced 
by  the  criticisms  of  others  in  their  group  to  radiate  a  reason- 
ably good  signal.  The  group  is  immediately  critical  of  a  bad

QST  for 


Happenii^#fff  the  Month 


NATIONAL  AMATEUR  RADIO  WEEK 

Senator  Prescott  Bush  of  Connecticut,  joined 
by  Senator  William  A.  Purtell  of  Connecticut  and 
Senator  George  A.  Smathers  of  Florida,  has 
again  this  year  introduced  into  the  Congress  a 
Resolution  (S.  J.  Res.  25)  to  designate  one  week 
in  the  month  of  June  each  jear  as  National  Ama- 
teur Radio  Week.  The  text  follows: 

Resolved  by  the  Senate  and  House  of  Representa- 
tives of  the  United  States  of  America  in  Congress 
assembled.  That  the  President  of  the  United  States 
is  authorized  to  designate  one  week  in  June  of 
each  year  as  National  Amateur  Radio  Week,  and 
to  issue  a  proclamation  inviting  the  people  of  the 
United  States  to  observe  the  week  with  appropri- 
ate exercises  to  further  and  stimulate  interest  in 
amateur  radio  in  the  United  States. 

The  measure  has  been  referred  to  the  Judiciary 
Committee  of  the  Senate.  If  passed  by  the 
Senate,  the  bill  will  then  go  to  the  House  for  simi- 
lar action.  We  understand  that  the  Federal  Com- 
munications Commission  has  endorsed  the  bill 
this  year,  and  this  action  is  interpreted  as  afTord- 
ing  the  measure  a  better  chance  than  last  year, 
when  a  similar  resolution  died  in  Committee.  It 
is  the  intention  of  the  language,  if  adopted,  to 
select  each  jear  the  week  ending  with  the  annual 
ARRL  Field  Day  tests. 

In  introducing  the  bill.  Senator  Bush  addressed 
his  colleagues  on  the  Senate  floor  as  follows: 

Mr.  President,  radio  amateurs  in  the  United 
States  have  made  invaluable  contributions  toward 
the  advancement  of  radio.  In  times  of  emergency, 
local  and  national,  they  have  performed  essential 
services  to  the  public  by  providing  a  network  of 
communications  linking  agencies  dealing  with 
disasters. 

Connecticut  is  especially  conscious  of  the  con- 
tribution to  the  general  good  made  by  these  men 
and  women,  afifectionately  known  as  "hams," 
because  the  American  Radio  Relay  League,  their 
official  organization,  has  its  headquarters  in  our 
State,  at  West  Hartford.  .  .  . 

The  month  of  June  was  selected  because  during 
that  month  each  year  is  held  the  American  Radio 
Relay  League's  annual  field  day  in  which  more 
than  7000  amateurs  throughout  the  country  set 
up  portable  and  emergency-powered  radio  com- 
munications in  remote  areas  and  man  the  gear  in 
shifts  for  24-hour  periods.  The  purpose  is  to  dem- 
onstrate the  skill  of  volunteer  amateur  radiomen 
in  providing  emergency  communications  ser\ace 
in  the  event  of  disaster  —  military,  civil  or  natural. 

The  week  of  this  event  would  be  a  most  appro- 
priate one  for  designation  as  National  Amateur 
Radio  Week. 

At  this  point  interested  amateurs  and  club 
groups  who  would  like  to  see  such  a  "week"  can 
help  b\^  writing  brief  letters  to  members  of  the 
Senate  Judiciary  Committee  urging  favorable 
action  on  the  resolution;  individuals  and  groups 


in  the  states  represented  on  the  Committee  can 
be  most  effective.  The  list  of  Senate  members, 
who  can  be  addressed  simply  at  the  U.  S.  Senate 
Office  Bldg.,  Washington,  D.  C,  is: 

Arkansas  —  John  L.  McClellan 
Idaho  —  Herman  Welker 
Illinois  —  Everett  M.  Dirksen 
Indiana  —  William  E.  Jenner 
Maryland  —  John  Marshall  Butler 
Mississippi  —  James  O.  Eastland 
Missouri  —  Thomas  C.  Hennings,  jr. 
North  Dakota  —  William  Langer 
SotUh  Carolina  —  Olin  D.  Johnston 
Tennessee  —  Estes  Kefauver 
Texas  —  Price  Daniel 
Utah  —  Arthur  V.  Watkins 
West  Virginia  —  Harley  M.  Kilgore 
Wisconsin  —  Alexander  Wiley 
Wyoming  —  Joseph  C.  O'Mahoney 

The  League  is  of  course  filing  a  statement  urg- 
ing its  adoption,  in  language  similar  to  that 
shown  on  page  53  of  May  1954  QST. 

F.C.C.  REGION  CHANGES 

In  January  FCC  completed  the  revision  of  its 
regional-office  set-up  by  dropping  the  regional 
office  at  Detroit  and  redesignating  supervisory 
responsibilities  to  the  Chicago  regional  office  in 
the  case  of  the  Detroit  district  office  (No.  19) 
and  to  the  New  York  regional  office  in  the  case  of 
the  Buffalo  district  office  (No.  20).  This  action 
has  no  effect  on  amateur  e.xamination  schedules, 
but  is  of  interest  to  TVI  committees  in  the  Detroit 
and  Buffalo  districts  since  they  will  now  have 
liaison  with  new  regional  offices. 

The  total  of  regional  offices  is  now  reduced  to 
si.x,  those  at  Houston  and  Anchorage,  Alaska, 
having  been  closed  last  year. 

REEXAMINATION  AMENDMENT 

To  clarify  the  eligibiUty  of  applicants  for  ama- 
teur licenses  to  take  another  e.xamination  after 
having  failed  one,  FCC  has  modified  the  lan- 
guage of  Sec.  12.49  of  our  rules.  It  now  says: 

Eligibility  for  re-examination.  An  applicant  who  fails  e.x- 
amination for  an  amateur  operator  license  may  not  take 
another  examination  for  the  same  or  a  higher  class  amateur 
operator  license  within  30  days,  except  that  this  limitation 
shall  not  apply  to  an  examination  for  a  General  Class  license 
following  an  examination  conducted  by  a  volunteer  exam- 
iner for  a  Novice,  Technician  or  Conditional  Class  license. 

The  principal  effect  is  to  make  it  plain  that 
failing  applicants  for  Novice  and  Technician 
Class  licenses,  now  all  handled  by  mail,  have  the 
same  privilege  as  those  failing  Conditional  Class 
—  i.e.,  to  appear  before  an  FCC  examiner  and 
take  the  General  Class  exam  without  waiting  30 
days.  In  fact,  they  can  go  up  the  very  next  day  if 
the}'  wish.

QST- Volume  III 


Parti  —  Foreword  to  Sumner  B.  Young's  (W0CO)  Index "^ 


VOLUME  III  was  the  first  complete  volume  to 
be  produced  under  the  guidance  of  a  full- 
time  editor.  Its  twelve  issues  extended  from 
August,  1919,  to  July,  1920.  Much  information 
lies  between  its  covers;  but  to  collect  and  to 
organize  it  is  often  very  difficult. 

By  all  odds,  the  most  important  story  recorded 
in  this  volume  was  the  development  of  amateur 
"tube"  transmitters  by  a  small  group  of  experi- 
mentallj'-inclined  and  progressive  amateurs; 
and  it  is  a  pity  that  the  material  in  QST  is  of  such 
nature  that  only  a  few  of  the  individual  partici- 
pants can  now  be  identified. 

No  large-scale  shifting  over  to  c.w.  transmitters 
occurred,  although  some  unsupported  general 
statements  published  in  the  magazine  may  imply 
the  contrary.  Later,  there  was  a  quickening  of 
interest  in  c.w.,  during  the  period  covered  liy 
Volume  IV;  but  the  real  rush  came  only  after  the 
results  of  the  first  successful  "Transatlantics" 
had  been  announced,  in  January,  1922.  See  Vol- 
ume V. 

Back  in  the  days  covered  by  the  two  postwar 
issues  of  Volume  II,  there  had  been  some  signs  of 
interest  in  c.w.  methods  of  transmission,  even 
before  the  Navy  had  lifted  the  "lid"  on  "send- 
ing." 1 

Volume  Ill's  first  offering  of  information  on  the 
subject  was  an  unsigned  article  called  "More 
About  V.T.  Transmitters."^  It  showed  a  circuit 
"found  quite  satisfactory  on  some  sets  supplied 


the  government  during  the  war,"  and  specified 
the  size  of  an  antenna  coil  for  200-meter  opera- 
tion. A  second  circuit  "developed  by  the  Marconi 
Company  especially  for  use  with  the  Marconi- 
DeForest  V.T.,  and  said  to  give  the  best  results 
for  that  tube  of  any  circuit  tested,"  was  dia- 
grammed. 

An  unusual  feature  of  this  article  was  a  sugges- 
tion that  c.w.  sets  be  developed  which  would  use 
the  same  tubes  for  transmitting  and  receiving; 
and  a  sketch  showing  a  possible  application  of  the 
idea  was  given.  The  author  (whoever  he  was) 
added:  "...  We  believe  that  the  ideal  c.w.  set 
of  the  future  will  incorporate  some  such  feature 
as  this."^^ 

An  announcement  at  24,  30,  September  1919, 
probably  referring  to  the  DeForest  Telephone  & 
Telegraph  Company,  read  as  follows: 

We  are  promised  that  soon  the  amateur  world  will 
have  a  bulb  transmitter  complete,  designed  primarily 
as  a  radiophone  but  also  an  efficient  c.w.  telegraph, 
and  at  a  reasonable  price.  It  sounds  almost  too  good 
to  be  true  but  we  believe  it  can  be  done.  This  set  is 
being  developed  by  a  prominent  commercial  com- 
pany and  should  be  announced  soon.* 

The  "Liberty  Number"  (November  1919), 
under  "Strays,"  carried  this  important  call  for 
information,  at  page  32: 

Anybody  working  c.w.  sets  on  200  meters?  We'd 


t  "QST—  Volume  I"  appeared  in  October,  1954,  QST, 
p.  40;  "QST — Volume  II"  appeared  in  February,  1955, 
QST.  p.  42. 

1  At  19,  June  1919,  J.  O.  Smith,  traffic  manager  of  the 
League,  said  that  many  stations  were  then  installing,  or 
planning  to  install,  undamped  transmitters;  and  he  pointed 
out  some  of  the  great  merits  of  these  sets. 

Warner's  "Essentials  of  V.T.  Transmitters"  had  ap- 
peared, at  3  to  6,  July  1919. 

An  unsigned  article  called  "On  Resuming  Transmitting," 
at  18  to  19,  July  1919,  had  characterized  v.t.  transmission 
as  "perhaps  the  most  important  development  of  wartime  radio 
from  our  standpoint."  [Italics  by  S.  B.  Y.] 

2  22,  24,  September  1919. 

2A  This  suggestion  was  repeated,  with  approval,  at  48, 
February  1920,  in  the  article  "Auto-Modulated  C.W. 
Telegraphy." 

^  See  the  ad  of  the  DeForest  Radio  Telephone  &  Tele- 
graph Company,  on  the  inside  back  cover  of  the  November, 
1919,  issue.  The  set  operated  on  60-cycle  110-volt  a.c;  and 
the  "tested  ranges"  were  stated  as:  "telephone  10  to  20 
miles,"  and  "telegraph  50  to  75  miles."  The  price  was 
$200.00,  complete,  including  bulbs.  The  operating  wave- 


lengths were  not  stated.  Rectifier-tubes  were  used  to  pro- 
duce h.v.  plate  current. 

*  I  can  testify,  from  experience,  that  the  early  amateur 
c.w.  transmitters  simply  would  not  work  on  wavelengths 
much  below  300  meters. 

See  the  "Editor's  Note"  appended  to  E.  W.  Whittier's 
article,  "A  Sure-Fire  C.W.  Circuit,"  at  29,  July  1921 
(Volume  IV). 

In  a  "C.W.  Building-Contest,"  conducted  by  the  Radio 
Club  of  Hartford,  it  was  specified  that  the  operating  wave- 
length of  the  transmitters  entered  in  the  competition  should 
not  exceed  200  meters.  Only  two  sets  submitted  would  "get 
down  "  even  as  low  as  200  meters.  These  were  built  by  F.  H. 
Schnell  (IMO)  and  J.  C.  Randall  (lANQ).  Both  rigs  would 
operate  as  low  as  180  meters.  See  24  to  25,  September  1921 
(Volume  V). 

At  13,  November  1921,  McMurdo  Silver  stated  that  it 
was  then  possible  to  operate  an  amateur  transmitter,  ef- 
ficiently, below  200  meters  (Volume  V).  At  63,  January 
1922  (Volume  V),  Kruse  (in  a  letter)  stated  that  c.w. 
transmitters  could  easily  be  operated  below  200.  At  50, 
February  1922  (Volume  V),  a  "Stray"  reported  that  9ZT 
could  "put  out"  one  ampere  of  c.w.  on  125  meters,  but  that 
he  could  find  nobody  who  was  equipped  with  a  receiver 
tuning  down  that  low. 


be  glad  to  have  a  description  of  any  that  are  proving 
successful.  We're  afraid  we're  going  to  have  lots  of 
trouble  with  200-meter  undamped.  The  frequency  is 
so  high  that  an  extremely  precise  adjustment  of  the 
heterodyne  frequency  must  be  made  at  the  receiver.* 

On  the  same  page,  right  below  this  item,  an- 
other Stray  referred  to  the  shortage  of  suitable 
transmitting  tubes  for  amateur  use : 

The  only  power  tube  available  for  us  seems  to  be 
the  so-called  Marconi  tube,  made  by  Moorhead  and 
licensed  by  DeForest  for  the  use  of  three  electrodes. 
The  Marconi  Co.  have  enjoined  DeForest  from  the 
manufacture  of  the  Oscillion,  on  the  grounds  that  it 
violates  the  Fleming  patents.  It  takes  rather  a 
stretch  of  the  imagination  to  see  how  this  can  be.^ 

A  motor  generator,  designed  to  produce 
h.v.  d.c.  for  plate  circuits  in  tube  transmitters, 
was  first  advertised  in  QST  in  the  Decem- 
ber, 1919,  issue.  The  International  Radio  Tele- 
graph Company,  of  326  Broadway,  New  York 
City,  offered  a  100-watt  unit  (200  ma.  at  500 
volts)  for  .1^75.00,  f.o.b.  factory. « 

In  any  event,  a  small  and  diversified  group  of 
amateurs  decided  to  pioneer  in  the  tube-trans- 
mitter field.  It  is  difficult  to  identify  and  to  locate 
them,  in  most  instances,  from  the  pages  of  QST; 
but  a  few  published  items  are  of  limited  assist- 
ance. 


At  34,  February  1920,  J.  O.  Smith  declared: 

.  .  .  The  short-wave  c.w.  set  has  arrived.  There 
is  no  doubt  but  that  the  development  of  these  short- 
wave c.w.  sets  will  greatly  add  to  the  interest  and 
welfare  of  amateur  radio.  A  few  of  these  sets  are  now 
in  operation  in  the  Atlantic  Division.   .   .   . 

At  48,  February  1920,  it  is  recorded  that 
2AB  (N.  y.  City)  worked  3ZH  (Trenton,  N.  J.) 
on  buzzer-modulated  telegraph}^,  with  1.1.  am- 
peres in  the  antenna;  and  that  8DA  (in  Ohio) 
heard  2AB's  signals  "verj-  QSA." 

At  28,  March  1920,  Entwistle's  Report  identi- 
fies Stuart  Briggs  and  Fred  Bowditch  (both  of 
Brookline,  Mass.)  and  Francis  Praj'  (of  Somer- 
ville,  Mass.)  as  the  owners  and  oj^erators  of 
"undamped  transmitters." 

The  April,  1920,  issue  of  QST  contained  an 
article  (probabl}'  by  Warner)  entitled  "The  Ad- 
vent of  Amateur  C.W."  ^  This  mentioned  some 
of  the  "pioneers": 

.  .  .  2ZV,  Richmond  Hill,  L.  I.,  is  using  a  340- 
meter  wave  for  c.w.  telegraphy,  compensated  wave 
.350  meters,  with  an  antenna  current  of  6  amperes, 
representing  350  watts.  The  oscillating  equipment  is 
two  Type  P  pliotrons.  This  station  should  be  good  for 
1500  miles. 

.  .  .  Others  we  know  of  are  2ZL,  2FS,  2AB,  2EX, 


^I  can  testify  that  a  fairly  active  "black  market  "for 
various  tubes  developed  around  Greater  Boston  shortly 
after  the  "lid"  was  lifted  on  transmitting.  "Western  Elec- 
tric" transmitting  tubes,  rated  at  5  watts,  could  be  had  for 
around  $10.00  or  $15.00  apiece. 

A  "Stray,"  on  page  32  of  the  November,  1919,  issue, 
stated  that  the  Marconi  v.t.  was  a  pretty  good  tube,  how- 
ever; and  tliis  paragraph  cited  the  success  achieved  by  a 
hurriedly-constructed  transmitting  set  which  had  been 
installed  aboard  the  U.  S.  S.  George  Washinglon.  Using  one 
Type  "RH"  Moorhead  tube,  that  ship  had  worked  Otter 
Cliffs,  Maine  (on  c.w.),  while  1200  miles  out.  The  plate 
voltage  was  only  750.  The  wavelength  used  was  not  stated. 

A  "Stray"  (at  24,  December  1919)  spoke  of  "salvaged" 
VT-2s  for  amateur  c.w.  transmitters.  I  am  glad  that  some 
"salvaging"  was  done.  A  year  or  two  would  have  been 
wasted,  if  "irregular"  supplies  of  tubes  had  not  been 
tapped. 

^54^,  December  1919.  Also,  see  the  "Stray"  at  24,  De- 
cember 1919,  which  reads:  "At  last  a  cheap  and  good 
motor  generator  set  for  high-voltage  d.c.  has  arrived.  .  .  . 
Its  lack  hereto/ore  has  been  the  big  drawback  to  amateur  V.T. 
iransmission.  .  .  ."  [Italics  by  S.  B.  Y.|  For  a  scheme  for 
converting  "ceiling-fan"  motors  into  h.v.  d.c.  generators, 
see  "Strays,"  at  43,  June  1920. 

Motor  generators  were  considered  an  expensive  item  by  most 
early  hams.  Also,  the  noise  and  vibration  from  them  were 
aiuioying. 

Some  of  the  biggest  boosts  later  given  to  c.w.  work  were 
furnished  by  the  development  of  other  means  of  producing 
h.v.  d.c.  First  came  the  electrolytic  rectifier;  and  then  came 
rectifier  tubes,  plus  filter  systems. 

On  the  advent  of  the  electrolytic  rectifier,  see:  "An 
Electrolytic  Rectifier  for  C.W.,"  by  P.  J.  Furlong  (IFF),  at 


17  to  18,  28,  February  1921  (Volume  IV).  For  its  later  de- 
velopment, see:  "A  Symposium  on  .\luminum  Electrolytic 
Rectifier  Operation,"  edited  by  S.  Kruse,  at  20  to  25,  June 
1922  (Volume  V). 

On  rectifier  tubes,  plus  filters,  see  the  following  references. 
In  Volume  III:  "Construction  of  a  500- Volt  Rectifier 
Transformer  for  C.W.  Work,"  by  Robert  Muns  (2ACQ), 
and  editorial  note  thereto  appended,  17  to  19,  June  1920.  In 
Volume  IV,  see:  9,  September  1920;  and  36,  November  1920 
(Russell's  report).  Volume  V  references:  28  to  29,  October 
1921  ("S"  Tubes,  with  smootlung  filter);  25,  .\pril  1922 
("Rectifier  Battle,"  at  Third  and  Fourth  District  Conven- 
tion) ;  and  12,  March  1922  (only  three  of  the  successful 
stations  in  the  "Second  Transatlantics"  used  tube-type 
rectifiers). 

On  h.v.  synchronous  rectifiers,  see  the  following  reference 
in  Volume  V:  18  to  19,  June  1922  (editorial  note).  The 
synchronous  rectifiers  never  achieved  wide  use. 

At  49,  November  1920  (Volume  IV),  .\rthur  K.  Ransom, 
in  a  letter,  expressed  the  opinion  that  the  need  for  produc- 
ing h.v.  d.c.  was  the  biggest  obstacle  to  the  widespread 
adoption  of  c.w.  transmitters  by  amateurs. 

"  13,  14,  16,  .\pril  1920. 

Note  that  NSF,  the  Naval  Radio  Laboratory  at  Anacos- 
tia,  Wasliington,  D.  C,  is  mentioned,  in  this  same  article 
(p.  13),  as  "testing  bulb  sets  of  various  powers  on  200  and 
425  meters,  using  straight  and  chopped  c.w." 

Also  note  that  some  experimental  work  by  the  Glenn  L^ 
Martin  Co.,  of  Cleveland,  is  mentioned:  "...  One  set 
puts  2.5  amperes  in  the  antenna  on  ISO  meters  with  250 
watts  input,  and  the  other  set  4  amperes  on  270  meters 
with  an  input  of  350  watts.  .  .  ."  [Italics  by  S.  B.  Y.] 

The  Glenn  L.  Martin  Co.  stations  used  Air  Service  calls 
(UM  and  CMC).  See  13,  April  1920.

2ZM,  8XK,  8Y0,  and  2XX.  2XX,  ex-2XG,  the 
station  of  Mr.  Robert  F.  Gowen  at  Ossining,  New 
York,  has  secured  perhaps  the  best  distance  to  date, 
signals  being  nightly  QSA  in  Little  Rock,  Arkansas. 
Voice  modulated  and  straight  undamped  are  used. 

.  .  .  Probably  the  most  interesting  work  is  that 
done  by  2ZL,  the  station  of  our  traffic  manager,  Mr. 
J.  O.  Smith.  That  the  c.w.  is  proving  up  is  attested  by 
the  fact  that  2ZL  is  junking  its  spark  set  as  outgrown. 
The  equipment  consists  of  a  few  small  oscillators  in 
parallel,  with  an  antenna  current  of  1.2  amperes, 
straight  c.w.  on  275  meters.  .  .  .  Traffic  has  been 
put  thru  to  Ohio  and  Massachusetts  by  this  station 
when  the  spark  signals  were  powerless  to  combat 
QRM  and  QRN.s  .  .  .  [Italics  by  S.  B.  Y.] 

J.  O.  Smith's  "Operating  Department  Report" 
(at  28,  April  1920)  adds  no  more  c.w.  stations  to 
the  list,  but  makes  this  encouraging  comment: 

,  .  .  Short-wave  c.w.  transmission  has  done  much 
more  than  was  expected  of  it,  in  that  it  has  turned 
out  to  be  a  very  docile,  tame  and  willing  worker, 
instead  of  a  fiy-by-night,  unreliable,  unsteady  means 
of  communication.  More  power  to  it.  .  .  . 

At  34,  January  1920,  the  "Calls  Heard"  list 
of  L.  E.  Furrow  (420  Lake  St.,  Troy,  Ohio)  states 
that  on  December  8,  1919,  he  heard  station  DA 
and  station  3ZH  working  one  another,  both  on 
c.w.  and  on  'phone.  This  is  the  first  mention  of 
v.t.  transmissions  by  amateurs  which  I  have  been 
able  to  find  in  that  particular  department  of  QST. 
DA  was  probably  an  unlicensed  station. 

The  one-tube  20-watt  c.w.  transmitter  of  Mr. 
Carter,  of  Cleveland  (call  UM),  is  referred  to  in 
8DA's  list  of  "Calls  Heard"  at  42,  March  1920. 
The  call  UM  appears  also  to  have  been  used  by 
the  Glenn  L.  Martin  Aircraft  Co.,  at  Cleveland; 
and  it  is  said  to  have  been  an  old  Air  Service  call. 
See  13,  April  1920,  and  the  editorial  note  to  the 
letter  from  H.  V.  Simmons,  at  54,  July  1920. 
However,  it  may  well  be  that  Mr.  Carter's  sta- 
tion, signing  the  call  UM,  was  an  unlicensed  sta- 
tion. 8DA  (at  Salem,  Ohio,  60  miles  away), 
stated  that  he  worked  UM  regularly. 

Don  Mix  (ITS,  of  Bristol,  Conn.),  whose 
"Calls  Heard"  lists  eventually  earned  him  the 
nickname  of  "Sleepless  Wonder,"  reported  hear- 
ing several  stations  on  'phone  and  modulated 


telegraphy.  See  his  list  at  51,  April  1920.' 

The  May  (1920)  issue  of  the  magazine  con- 
tained another  leading  article  (unsigned)  en- 
titled: "An  Experimental  C.W.  Transmitter."^'' 
It  featured  the  Colpitts  circuit,  described  as  "a 
little  complex,  but  beautiful  in  principle."  ^^  For 
amateur  use,  Western  Electric  VT-2s,  General 
Electric  VT-14s,  and  Class  II  Marconi  bulbs  were 
recommended.'^ 

This  May  (1920)  issue  also  contained  a  state- 
ment by  J.  O.  Smith,  at  page  26,  indicating  that 
many  amateurs  desiring  efficient  transmitters 
had  installed  c.w.  rigs.  No  statistics  were  given. 

At  page  31  of  this  same  number,  R.  H.  G. 
Mathews  (9ZN)  said  that  he  was  thinking  of 
adding  a  ]/2-kilowatt  c.w.  transmitter  to  his  sta- 
tion during  the  coming  summer  or  fall  of  1920. 
This  was  real  news,  because  in  March  (1920) 
9ZN's  spark,  on  275  meters,  had  established  a 
new  record  for  amateur  stations.^' 

The  June  (1920)  issue  carried  an  announce- 
ment that  the  Nola  Radio  Club  (of  New  Orleans, 
Louisiana)  was  experimenting  with  radiophones 
and  c.w.  sets.'* 

At  page  51  of  the  same  issue,  O.  A.  Gulledge 
(4AT),  of  Ft.  Pierce,  Florida,  announced  (by 
letter)  that  he  had  installed  a  DeForest  "Oscil- 
lion"  radiophone;  and  that  he  would  send  out 
"music,  speech,  and  c.w.  signals,"  at  stated 
times,  on  WO  meters. 

A  well-written  article,  showing  touches  of  true 
wit  and  humor  besides,  was  published  at  15  to 
17,  July  1920:  "C.W.  for  the  Amateur,"  by 
Howard  L.  Stanley  (2FS).'^  He  described  a  c.w., 
m.c.w.,  and  'phone  transmitter  which  he  had 
developed  with  the  help  of  2ZL  (J.  O.  Smith). 

More  generalities  appeared  in  Warner's  edi- 
torial (called  "C.W.")  at  page  24  of  the  July, 
1920,  issue: 

Reports  from  all  over  the  country  show  the 
gradual  but  sure  trend  from  spark  to  undamped  in 
amateur  radio,  just  as  we  thought  would  develop, 
and  we  are  glad  to  see  it. 

We  are  strongly  in  favor  of  c.w.  and  are  going  to 
do  all  we  can  to  help  it  along.   .  .   . 

We  are  on  the  eve  of  a  great  transition  in  amateur 
methods.  We  plead  for  the  undamped  the  serious 
consideration  that  its  many  advantages  merit. 


*  The  final  paragraph  in  this  article  (16,  April  1920) 
contains  this  interesting  language:  "The  Editor  urges  the 
adoption  of  c.w.  by  all  serious  experimenters  as  a  field  of 
highest  interest  and  unlimited  possibilities,  but  with  the 
warning  that  they'll  have  to  learn  transmission  all  over,  for 
the  old  dope  of  spark  days  will  not  apply.  QST  hopes  in 
the  near  future  to  establish  a  special  laboratory  for  c.w. 
experiments  looking  toward  the  development  of  sets  par- 
ticularly adapted  to  200-meter  relay  work." 

"  He  listed  the  following:  2XG  ('phone  and  modulated 
telegraphy);  2XJ  ('phone);  2XX  ('phone  and  modulated 
telegraphy);  2ZL  (spark  and  modulated  telegraphy);  2ZV 
(spark  and  modulated  telegraphy);  SCO  ('phone);  and 
8XU  (spark  and  modulated  telegraphy). 

A  few  more  early  tube  sets  can  be  identified  by  referring  to 
other  lists  of  "Calls  Heard,"  in  later  numbers  of  Volume  III 
of  QST. 

At  44  to  45,  July  1920,  ITS  reported  hearing  lAW  on 
spark  and  'phone;  2FS  on  spark  and  c.w.;  2XB  on  c.w.  and 
'phone;  and  2XK  on  spark  and  modulated  c.w. 

At  46,  July  1920,  the  Waverly  (N.  Y.)  Radio  Research 
Assn.  reported  hearing  2XA  (on  "Tel."). 

8LF  (Crafton,  Penn.)  reported  hearing  8CB   (on  spark 


and  "Mod."),  during  May,  1920.  His  list  is  at  55,  August, 
1920. 

The  later  list  of  the  "Sleepless  Wonder"  (ITS),  found  at 
55,  August  1920,  which  records  results  obtained  at  Bristol, 
Conn.,  between  May  18  and  June  20,  1920,  speaks  of 
working  lAY,  who  used  spark.  Mod.  c.w.,  and  'phone;  and 
of  hearing  2QR's  spark,  c.w.,  and  'phone  signals. 

Note  that  the  Editor  of  QST  had  announced  (at  48, 
February  1920)  that  he  would  be  pleased  to  receive  reports 
of  amateur  v.t.  transmissions. 

10  5  to  8,  May  1920. 

11  5,  May  1920. 

12  6,  May  1920.  The  article  added  that  only  the  Class  II 
Marconi  tubes  were  "now  regularly  available  on  the  mar- 
ket for  communication  purposes." 

'3  On  March  9,  1920,  9ZN's  275-meter  spark  set  was 
copied  aboard  a  vessel  lying  in  Colon,  Panama.  On  March 
12,  1920,  the  same  ship  heard  him  when  200  miles  south  of 
Balboa.  See  8,  May  1920.  (Incidentally,  the  next  day  — 
March  13th  —  the  vessel  caught  fire  at  sea  and  was  de- 
stroyed. All  hands  were  saved.  See  8,  May  1920.) 

14  45,  June  1920.  The  club  is  identified  on  38,  June  1920.

QST  for 


In  the  same  issue,  Traffic  Manager  J.  O.  Smith 
(2ZL)  was  equally  vague  as  to  how  many  stations 
were  shifting  over  to  tube  sets,  and  where  those 
stations  were,  although  he  said  that  a  trend  was 
developing: 

.  .  .  The  long-heralded  change  from  spark  to 
continuous-wave  transmission  is  now  in  full  swing, 
and  in  quite  a  number  of  cases  spark  sets  have  al- 
ready been  discarded.   .   .  . 

Amateur  radio  is  now  in  transition  from  spark  to 
C.W.,  and  a  complete  change-over  is  merely  a  ques- 
tion of  time.'^  .   .   . 

I  wish  I  felt  competent  to  make  a  fairly 
accurate  estimate  of  how  many  amateurs  were 
actively  engaged  in  c.w.  work,  as  of  July  1, 
1920,  and  concerning  their  geographical  dis- 
tribution; but  I  simply  cannot  do  it.  My  best 
guess  is,  that  as  of  that  date,  there  were  not  over 
200  v.t.  transmitters  in  operation,  in  amateur 
stations,  in  the  entire  U.  S.  A. 

This  brings  us  to  a  study  of  the  data  published 
(in  Volume  III  of  QST)  bearing  on  the  number 
of  licensed  hams  in  the  United  States,  and  in- 
dicating their  distribution  throughout  the  nine 
Districts. 

The  material  is  incomplete,  and  unanalyzed. 
QST  published  lists  of  calls  of  new  amateur  sta- 
tions, as  follows:  42  to  43,  November  1919;  10 
to  14,  December  1919;  a  separate  supplement  to 
the  January,  1920,  issue,  containing  15  pages  of 
call  letters;  39  to  40,  April  1920;  35  to  36,  May 
1920;  35  to  36,  June  1920;  and  41  to  42,  July 
1920.  The  January,  1920,  supplement  was  a 
cumulative  affair.  Starting  with  it,  and  adding 


further  amateur  calls  published  thereafter  (and 
eliminating  all  calls  published  by  way  of  correc- 
tion), I  get  the  following  picture:

The  main  trouble  with  these  data  is  that  they 
give  us  no  inkling  of  the  dates  as  of  which  the 
various  lists  were  accurate  and  complete. 

Evidently,  the  Editor's  idea  was  to  devote 
two  pages  per  issue  to  the  publication  of  new 
calls,  and  to  catch  up  as  best  he  could,  at  this 
unchanging  rate;  ^^  and  I  have  now  confirmed 
my  suspicion  that  these  lists  were  a  good  distance 
behind  the  actual  march  of  events,  as  of  (say) 
July  1,  1920.  It  is  a  pity  that  somebody  like 
Edgar  Felix  did  not  get  the  correct  and  complete 
figures  from  government  sources  and  analyze 
them  for  QST's  readers. 

Mr.  Entwistle  presented  some  interesting  facts 
re  the  number  of  licensed  amateur  stations  in 
the  First  District  in  the  June  (1920)  issue,  at 
page  25.  Just  when  he  "put  pen  to  paper"  is  not 
stated ;  but  he  said : 


1^  Anybody  who  had  the  experience  of  working  with  one 

of  the  early  "tube"  sets  will  get  a  good  laugh  out  of  Stan- 
ley's description  of  his  troubles. 

Looking  back  at  my  log  for  July  21,  1920,  I  find  that  I 
first  tried  to  operate  a  tube  transmitter  (built  for  me  by  the 
Atlantic  Radio  Co.  of  Boston,  Mass.),  on  that  date.  All  I 
accomplished  was  the  burning-out  of  the  plate-current 
meter,  and  the  melting  of  the  glass  envelope  on  one  of  the 
four  "  VT-2  "  transmitting  tubes. 

After  IDH  (E.  W.  Whittier,  himself)  had  made  some  re- 
pairs, I  got  J^  amp.  into  my  antenna,  at  Duxbury,  Mass., 
on  Saturday,  August  7,  1920. 

My  first  contact  was  a  local —  IRAA.  I  worked  him  on 
c.w.  and  buzzer-modulated  c.w.  on  August  8,  1920.  The 
"radiophone"  part  of  my  rig  wouldn't  work  at  all. 

On  Sunday,  November  21,  1920,  after  more  help  from 
Whittier,  and  after  I  had  moved  my  set  back  to  Dorchester, 
Mass.,  I  got  0.7  amp.  into  a  big  "cage"  antenna,  at  my 
station  (lAE),  on  360  meters;  and  I  worked  IPAI,  and  was 
heard  by  IKAY,  in  Portland,  Maine. 

More  changes,  made  mostly  by  IDH  (who  worked  for 
Atlantic  Radio),  followed.  The  first  real  traffic  handling 
which  I  ever  did,  on  c.w.,  was  in  the  early  hours  of  Sunday, 
December  26,  1920.  Between  1:18  a.m.  and  2:34  a.m.,  I 
sent  9  messages  to  ITS  (Bristol,  Conn.),  on  260  meters.  lES 
kindly  helped  on  the  receiving  work. 

On  January  27,  1921,  I  received  written  permission  from 
H.  C.  Gawler,  RI  of  the  First  District,  to  operate  on  c.w. 
at  325  meters,  for  30  days,  commencing  February  15,  1921, 
to  try  to  establish  reliable  communication  with  2ZL.  Some 
interesting  results  followed. 

Mr.  J.  O.  Smith  (2ZL)  really  had  a  fine  station.  At  27, 
April  1921  (Volume  IV),  it  was  referred  to  as  being  probably 
the  most  powerful  amateur  c.w.  station.  See,  also:  editorial, 
"The  Berries!"  at  29,  March  1921;  and  48,  May  1921. 
(Both  in  Volume  IV.)  Also,  look  at  13,  April  1920;  and  28, 
April  1920.  (Both  in  Volume  III.) 

1®  26,  July  1920.  The  reports  of  the  division  managers 


which  follow  Mr.  Smith's  general  remarks  (in  that  same 
issue)  shed  little  light  on  the  subject,  either. 

Entwistle  (New  England  Division)  made  this  statement 
(at  27,  July  1920):  "...  One  significant  fact  that  stands 
out  as  inspiring  is  the  gradual  C-W-izing  of  New  England. 
The  following  have  c.w.  sets:  Wood,  Arnold,  Winchester; 
ICK;  IXF.  Providence;  Mass.  Radio  School;  lYC;  lAY; 
IQP." 

The  Northwestern  Division  Report  (33,  July  1920)  in- 
cludes these  words  by  Acting-Manager  Hertz:  "...  The 
tests  conducted  by  7CR.  7ZB  and  7CW  with  the  Forestry 
servnce  radiotelephone  sets  have  made  us  reluctant  to  hang 
up  our  'phones.  It  is  interesting  to  note  that  the  c.w.  radiat- 
ing 0.46  ampere  and  spark  signals  radiating  1.5  to  2  amperes, 
both  at  Portland,  are  equal  in  audibility  at  7CW,  about  40 
miles  distant.  ..." 

The  Ontario  Division  Report  (34,  July  1920)  states  that 
there  are  presently  four  amateurs  with  c.w.  sets  in  the  City 
of  Toronto,  with  others  ready  to  build  tube  sets  almost  at 
once.  The  situation  is  described  thus:  "...  A  great  transi- 
tion seems  to  be  taking  place  in  the  Toronto  district.  Every-^ 
thing  seems  to  point  to  the  fact  that  c.w.  and  radiotelephony 
are  going  to  entirely  replace  spark  telegraphy  in  this  district 
with  all  advanced  amateurs  in  the  very  near  futiire.  ..." 

The  evidence,  in  other  words,  of  an  actual  "shifting- 
over,"  was  very  indefinite,  and  very  "thin." 

Astute  amateurs  who  had  experienced  the  advantages  of 
c.w.  sets  could  confidently  predict  the  end  of  spark  trans- 
mitters; but  nobody  except  a  small  group  of  "pioneers" 
had  yet  "gone  over"  to  tube  sets. 

'"See  39,  April  1920:  "Fellows,  devoting  a  half  dozen 
pages  per  issue  to  calls  got  to  where  it  detracted  from  the 
reading  value  of  QST  and  scared  us.  Then  we  hoped  to  pub- 
lish monthly  supplements  carrying  advertising  to  finance 
the  thing,  but  the  Post  Office  Dept.  has  just  come  out  best 
in  an  argument  on  that.  So  we  resume  in  QST  —  two  pages 
a  month  until  we  get  them  all.  You  can  cut  out  this  sheet 
and  keep  it  with  the  .Januarj'  supplement." 


March  1955

At  the  time  of  writing  this  report  there  are  1125 
licensed  amateur  stations  of  the  first  and  second  class 
in  the  First  Radio  Inspection  District  with  probably 
90%  of  the  total  number  of  the  former  grade.  Only 
one  special  amateur  license  has  been  issued,  and  that 
is  located  at  Springfield,  Mass.  (Mr.  Sabin).  One 
additional  school  license  has  been  issued,  to  Dart- 
mouth College,  call  letters  lYB.  The  other  technical 
school  license  was  granted  previously  to  the  Rhode 
Island  State  College,  call  lYA.  Naturally  the  dis- 
tribution of  these  stations  varies  from  state  to  state 
and  in  different  parts  of  the  same  state.  Greater 
Boston  has  the  greatest  density  per  capita;  Wollaston, 
the  most  of  any  one  city.  .  .  .  [Italics  by  S.  B.  Y.] 

Note  that  the  number  of  Hcensed  amateur 
stations  in  the  First  District  alone,  according  to 
Mr.  Entwistle,  totaled  1125.  His  report  probably 
was  written  sometime  in  May  (1920),  and  pos- 
sibly was  written  in  April  of  that  year.  The  time 
lag  between  the  list  of  calls  published  in  QST 
and  the  actual  licensings  of  the  stations  them- 
selves is  strikingly  illustrated,  when  this  1125 
figure  is  compared  to  the  458  First  District  calls 
printed  in  QST  up  to  and  including  the  July 
(1920)  issue,  and  when  it  is  compared  with  the 
total  of  1521  calls  for  the  entire  U.  S.  A.,  so 
published.^"* 

It  is  interesting  to  see  that  the  Fourth  Distiict 
still  occupied  the  last  position  in  total  number  of 
stations  licensed. ^^ 


As  more  and  more  stations  came  onto  the  air, 
the  QRM  problem  became  acute,  especially 
around  the  larger  cities. 

In  addition  to  the  suggestion  that  tube  trans- 
mitters be  used  in  place  of  the  "good  old"  spark 
sets  —  an  impossibility  until  such  time  as  power 
tubes  and  other  essentials  should  become  gen- 
erally available  to  amateurs,  and  until  decent 
c.w.  receivers  should  be  produced  —  two  tech- 
nological approaches  were  recommended.  One  of 
them  was  the  use  of  highly-directional  under- 
ground receiving  antennas;  and  the  other  was  the 
use  of  wavelengths  below  200  meters,  by  low- 
powered  spark  transmitters. 

As  to  the  use  of  underground  antennas,  the 
literature  is  scanty.  It  is  certain  that  only  a  very 
few  amateurs  actually  experimented  in  this  field. 
The  need  for  elaborate  shielding  of  all  leads  to 
the  underground  wires,  and  the  necessity  for 
employing  elaborately-shielded  receivers,  or  com- 
pletely-screened receiving  rooms,  offered  serious 
practical  drawbacks.  However,  a  handful  of 
amateurs  made  the  effort.  They  found  some 
refuge  from  static,  and  verified  the  fact  that  at 
short  wavelengths,  underground  antennas  ex- 
hibited marked  directional  properties.^" 

Part  II  of  W0CO's  index  to  Volume  III  of 
QST  will  appear  in  our  April  issue.  —  Ed. 


'8  Including  the  July  (1920)  list,  at  41  to  42,  July  1920,  a 
grand  total  of  1521  U.  S.  A.  calls  and  58  Canadian  calls  had 
appeared  in  the  QST  lists. 

The  late  Clinton  B.  DeSoto,  at  page  61  of  Two  Hundred 
Meters  and  Down,  said:  ".  .  .  At  the  end  of  the  fiscal  year, 
June  30,  1920,  the  number  of  amateur  stations  had  grown 
to  56  per  cent  of  all  stations  licensed  by  the  U.  S.  Govern- 
ment. The  Department  of  Commerce  reported  that  there 
were  5719  amateur  stations,  fifteen  times  as  many  as  all 
other  types  of  land  stations  put  together.  Although  this 
was  370  fewer  than  in  1917  when  all  amateur  stations  were 
closed  down,  the  disparagement  was  not  due  to  decreased 
interest  but  to  the  fact  that  a  number  of  amateurs  were 
either  still  in  the  service  or  were  fully  occupied  in  commer- 
cial operating  or  manufacturing  activities.  .   .  ." 

The  best  estimate  which  I  was  able  to  make,  from  the 
data  in  QST  before  I  found  this  reference,  was:  5000  ama- 
teurs as  of  July  1,  1920.  I  reached  this  by  first  multiplying 
1521  by  2.45.  (The  "2.45"  was  obtained  by  dividing  the 
First  District  "published"  figure  into  Entwistle's  First- 
District  figure.)  The  multiplication  gave  3726.45.  To  this, 
I  added  1200  (my  estimate  of  2  months'  new  licensing), 
getting  4926.45.  This  I  rounded  off  to  5000.  Such  are  the 
"fruits"  of  incomplete  figures. 

19  Look  back  at:  163,  185,  July  1916;  footnote  8,  page  7, 
of  my  "Foreword  to  the  Index  to  Volume  I  of  QST";  32, 
April  1917;  and  pages  11  to  12  of  my  "Foreword  to  the 
Index  to  Volume  II  of  QST." 

2"  The  only  amateur  experimenters  referred  to,  in  QST, 
so  far  as  I  can  see,  were  R.  H.  G.  Mathews  {9ZN),  wlio  was 
chief  engineer  of  tlie  Chicago  Radio  Laboratory,  and  some 
members  of  the  Nola  Radio  Club,  at  New  Orleans,  La.  See 
"The  Underground  Antenna  Adapted  to  Amateur  Waves," 
by  Mathews,  at  14  to  16,  June  1920;  and  at  18  to  19,  July 
1920.  The  item  re  the  Nola  Radio  Club  is  under  "The 
Affiliated  Clubs,"  at  45,  June  1920. 

The  first  reference  to  underground  antennas  for  amateur 
use  that  I  have  found  in  QST  appears  in  an  advertisement 
of  Chicago  Radio  Laboratory,  at  44,  August  1919.  It  points 
out  the  merits  of  an  audio  amplifier.  This  ad  states:  "Static 
elimination  by  use  of  the  Rogers  underground  antennae  is 
perhaps  the  most  striking  and  far-reaching  discovery  made 
during  the  war.  By  this  system  'static'  is  absolutely  elimi- 


nated, the  only  atmospheric  interference  being  due  to 
ground  strays.  In  cutting  out  the  static,  however,  the  signal 
strength  on  200  meters  is  also  reduced  to  about  one-eighth 
of  tlie  value  of  the  same  signal  on  the  ordinary  antenna.  In 
order  to  render  ordinary  signals  readable  on  the  under- 
ground antenna  it  is  therefore  necessary  to  use  one  or  more 
steps  of  amplification.   .  .  ." 

Mathews  had  become  acquainted  with  the  work  done  by 
Rogers,  and  with  the  later  experiments  conducted  by  A. 
Hoyt  Taylor  (Lt.  Commander,  USNRF),  through  his 
(Mathews')  association  with  the  Great  Lakes  Radio  Labo- 
ratory during  World  War  One.  See  30,  November  1919.  For 
Taylor's  articles  on  short-wave  and  long-wave  spark  and 
undamped  reception,  with  subterranean  or  submarine 
wires,  see:  "Short- Wave  Reception  and  Transmission  on 
Ground  Wires  (Subterranean  and  Submarine) ",  7,  Proc. 
I.R.E..  337-361  (August,  1919);  "Long- Wave  Reception 
and  the  Elimination  of  Strays  on  Ground  Wires  (Subter- 
ranean and  Submarine) ",  7,  Proc.  I.R.E.,  559-583  (De- 
cember, 1919);  and  "The  Use  of  Ground  Wires  at  Remote 
Control  Stations,"  8,  Proc.  I.R.E.,  171-190  (June,  1920). 
(The  last  of  these  3  articles  was  written  by  Taylor  and  by 
A.  Crossley,  Lieut,  (j.g.),  USNRF.) 

The  best  practical  results  had  been  obtained,  in  the  Navy, 
in  the  reception  of  long-wave  spark  and  imdamped  trans- 
Atlantic  signals;  and  after  April  7,  1918,  all  such  reception, 
at  the  Belmar,  N.  J.,  station,  had  been  conducted  by  the 
use  of  submarine  wires,  "balanced"  against  a  "ground" 
wire,  or  against  a  loop  antenna.  See  pages  570-572,  Volume 
7,  Proc.  I.R.E.  (December,  1919). 

Some  success  with  the  reception  of  ship-to-shore  traffic 
on  600  meters  had  been  demonstrated.  See  descriptions  of 
"Remote-Control  Stations"  at  Great  Lakes,  Hampton 
Roads,  and  New  Orleans,  at  175-189,  8,  Proc.  I.R.E. 
(June,  1920). 

On  the  Iransmitling  side,  the  best  work  had  been  between 
Great  Lakes  and  Chicago,  a  distance  of  36  miles.  (See  7, 
J'roc.  I.R.E.,  360,  .\vigust  1919).  The  first  transmissions  — 
about  .January,  1918  — had  been  on  340,  600,  and  720 
meters.  (See  7,  J'roc.  I.R.E.,  356).  .\  few  weeks  later,  450 
and  550  meters  had  been  used.  (See  7,  Proc.  I.R.E.,  357). 
At  Chicago,  Mr.  A.  L.  Howard's  receiving  station  had  been 
utilized.  (See  7,  Proc.  I.R.E.,  356).

Recently  W5TYM  rounded  up,  from  Hq.  and 
other  sources,  background  material  for  a  ham 
radio  story  to  be  used  in  his  company's  house 
organ.  There  must  have  been  some  potent  argu- 
ments there  —  John  Wood  of  the  public  relations 
department  is  now  WX5FLSI 


On  Januarj'  31st  the  Henrj'  Radio  Store, 
Butler,  Mo.,  was  broken  into  and  the  following 
equipment  stolen:  two  Collins  75A-3s  (serials 
1573  and  1585),  one  Collins  32V-3  (serial  1489), 
one  Elmac  PMR-6.\  (serial  3096)  and  one  Elmac 
PSR-12  (serial  554  j. 

A  reward  will  be  paid  b\'  Robert  Henry,  owner 
of  the  store,  to  anyone  giving  information  leading 
to  the  arrest  and  conviction  of  the  person  or 
persons  participating  in  the  crime.  Compensation 
will  also  be  made  for  the  return  of  the  equipment. 


In  recent  measurements  by  the  National 
Bureau  of  Standards  the  velocity  of  liglit  has 
been  redetermined.  I'sing  the  molecular  constants 
method,  the  new  value  obtained  was  2;t9,792,0(K) 
±6000  meters  per  second;  by  the  radio  interfer- 
ometer method,  the  new  velocity  value  was 
299,795,100  ±3100  meters  per  second. 


We  are  saddened  to  report  the  passing  of 
Theodore  G.  Deiler,  Engineer-in-Charge  of  the 
FCC  8th  Radio  District.  In  1919.  Mr.  Deiler 
began  his  career  with  the  Radio  Division  of  the 
Department  of  Commerce.  While  with  that 
organization  he  became  Supervisor  of  Radio  at 
New  Orleans,  La.  With  the  transfer  of  the  Radio 
Division  to  the  Federal  Communications  Com- 
mission, he  was  designated  Inspector-in-Charge 
and  later  became  Engineer-in-Charge. 

Mr.  Deiler  was  very  well-known  and  respected 
in  the  radio  industry'  and  among  amateurs.  The 
thousands  of  commercial  and  amateur  radio  op- 
erators who  were  licensed  under  his  supervision 
will  mourn  his  passing. 


There  are  man\-  new  amateurs  in  and  around 
Davenport,  Iowa,  thanks  to  the  Davenport 
Radio  Club.  W0HMM  reports  on  a  new  series  of 
classes  sponsored  by  the  DRAC  incorporating 
the  best  training  features  of  lectures,  films, 
and  experiments,  .\fter  observing  a  few  of  the 
lectures,  the  faculty  of  St.  Ambrose  College 
volunteered  full  use  of  the  college  laboratory 
and  projection  rooms  to  the  Davenport  club, 
in  recognition  of  their  outstanding  program. 


Your  (lull's  educational  program  may  be  able 
to  utilize  the  club  code  award  shown.  Any 
reasonable  amount  of  these  certificates  will  be

AMONG  our  YLs  there  are  some  (too  few,  alas!) 
\  who  are  "dyed-in-the-wool"  v.h.f.  opera-

operating  and  experimenting  on  the  higher 
frequencies  —  they  do  what  they  can  to  create 
activity  and  interest  in  the  world  above  50  Mc. 
Liane  Waite,  W2FBZ,  is  another^  YL  who  is 
so  enthusiastic  about  v.h.f.  operation  that  she 
is  happy  to  do  what  she  can  to  help  swell  the 
population  in  the  upper 
segment  of  the  ham 
bands.  And,  as  WlHDQ 
has  said,  "this  is  the  gal 
who  has  won  several 
Northern  New  Jersey 
section  awards  in  our 
v.h.f.  contests,  and  has  a 
few  times  posted  the  top 
score  for  the  country." 
In  the  Sept.,  1953,  V.H.F. 
Party,  Liane  followed  in  W2FBZ 

second   place   nationally  ^xot^tt^^  t> 

another  leading  YL  v.h.f.  operator,  W8BFQ.  Re- 
ferring to  Margaret  and  Liane,  WlHDQ  wrote 
in  Q.ST  for  Jan.,  1954:  "...  two  topnotch  v.h  t. 
YLs  whose  untiring  efforts  have  earned  thena  the 
respect  of  v.h.f.  men  everywhere."  In  the  June, 
1954,  Party,  Liane  made  the  country's  high  score 
in  the  single-operator  class.

We  met  a  congenial  group  of  local  hams  who 
were  interested  in  higher  frequencies,  and  I  be- 
lieve that,  more  than  anything  else,  caused  a 
continuation  of  interest  in  those  bands,  even 
after  obtaining  the  General  Class  hcense.  We 
became  interested  in  contests,  which  I  feel  is  one 
of  the  greatest  ways  for  checking  gear  and  pro- 
moting the  building  of  new  gear.  Because  of  this, 
we  got  on  220  and  432  —  at  the  same  time  we 
were  on  6  and  2  meters.  We  are  interested  in  1215 
and  hope  to  be  on  that  band  by  next  spring. 

There  is  quite  a  challenge  to  me  in  operating 
frequencies  where  it  is  possible  to  accomplish 
something  that  has  not  been  done  before.  We  are 
interested  in  carrying  on  any  v.h.f.  schedules 
which  would  be  desirable  to  set  up,  and  we  have 
two  goals.  One  of  them  is  to  work  Florida  on  2 
meters;  the  other  is  to  work  England. 

May  Liane  soon  realize  both  goals,  and  may 
her  words  encourage  more  YLs  to  take  to  the 
higher  frequencies. 

Reminder! 

YLs  and  OMs  —  don't  forget  your  date  to  meet  in  the 
Sixth  Annual  YL-OM  Contest  on  M^rch  5th-6th  and 
19th-20th.  Complete  details  were  on  page  49,  February  Qt>  1 . 

And  speaking  of  OMs  —  we  are  encouraged  and  perhaps 
a  bit  flattered  to  realize  how  much  mail  for  his  department 
cories  from  them.  The  proverbial  "battle  of  the  sexes 
seems  nonexistent  in  our  hobby;  rather,  the  spirit  is  one  of 
r^utual  respect,  enthusiasm,  and  cooperation.  We  re  always 
pleased  to  hear  from  OM  readers  and  hope  that  their  in- 
terest in  the  distafT  side  will  continue!

CONDUCTED  BY  EDWARD  P.  TILTON,  WIHDQ 


ALONG  about  the  last  week  in  January  each 
/\  year  you  can  measure  v.h.f.  activity  with  a 
-^  ■*-  ruler  —  a  ruler  alongside  the  logs  mailed  in 
to  Headquarters  following  the  Annual  V.H.F. 
Sweepstakes.  Time  was  when  a  pile  an  inch  high 
looked  big  for  a  v.h.f.  contest.  But  you  need  the 
better  part  of  a  one-foot  scale  for  the  eighth  run- 
ning of  this  popular  event,  January  8th  and  9th. 

When  you  look  through  the  comments  accom- 
panying the  entries,  you  find  things  Uke  "Never 
heard  so  many  signals  in  my  life"  —  "Activity 
here  was  at  an  all-time  high"  —  "  Had  to  peel  the 
signals  off  in  layers" — -"New  contacts  were 
made  right  up  to  the  last  minute!"  Nobody  re- 
ported conditions  as  being  good,  but  there  seems 
little  doubt  that  the  1955  event  will  break  all 
previous  records  for  v.h.f.  contests. 

At  least  a  dozen  participants  reported  more 
than  200  contacts  each,  K2CMB/2  leading  with 
248.  W2TBD  made  225  contacts  on  144  Mc. 
alone.  The  country's  top  score,  so  far,  is  W2UK's 
6336  points,  made  possible  through  the  amazing 
total  of  18  ARRL  sections  worked  on  144  Mc. ! 
Last  year's  record  score  of  3952  points,  by 
WIRFU,  was  topped  by  at  least  8  contestants, 
with  W2RGV,  WlUIZ/1  and  WIRFU  all  over 
5500  points. 

Club  records  seemed  sure  to  fall,  though  the 
big-club  totals  have  not  been  checked  as  we 
write.  The  South  Jerse}^  Radio  Association  seem 
to  have  maintained  their  near-monopoly  on 
V.H.F.  SS  gavel  awards,  their  claimed  total 
for  1955  running  over  the  50,000-point  mark. 
Their  perennial  competitors,  the  York  Road 
Radio  Club,  from  just  across  the  Delaware  River, 
outdid  their  previous  efforts,  and  it  looks  like  a 
close  one  between  these  two  rivals.  Several 
smaller  clubs  posted  totals  that  would  have  been 
good  for  top  place  a  few  years  back,  and  the  num- 


ber of  clubs  participating  was  well  up  over 
previous  years. 

Propagation  appeared  close  to  the  winter 
average,  from  your  conductor's  vantage  point. 
This  would  have  meant  a  quiet  Sunday  afternoon 
and  evening  in  years  past,  as  the  field  would 
have  been  prett}'  thoroughly  covered  bj-  noon  of 
the  second  day.  But  not  in  1955.  The  2-met«r 
band,  particularly,  was  jumping  with  activity, 
right  down  to  the  last  minute.  There  was  never 
an  hour,  including  those  just  before  dawn  on 
Sunday  morning,  when  it  was  not  possible  to 
make  hay  in  this  contest.  In  manj-  areas  j'ou  no 
longer  post  a  winning  total  and  get  anything  like 
a  normal  night's  rest  in  a  V.H.F.  SS  week  end! 

Through  the  Middle  West  many  operators 
reported  conditions  the  worst  they'd  seen  all 
winter.  Particularly  west  of  the  Mississippi, 
contacts  were  made  only  over  short  distances. 
But  still  we  find  reports  coming  in,  in  better  than 
former  numbers,  from  most  of  this  territory. 
Far-western  v.h.f.  men,  too,  report  the  going 
rough,  but  there  are  some  good  W6  and  W7  logs 
coming  in,  with  the  deadline  for  their  mail  still 
a  few  days  awaj''  as  we  write. 

There  was  heartening  evidence  of  new  v.h.f. 
activity  in  many  quarters.  They  won't  hit  a 
high  spot  in  the  national  scoring,  because  of 
their  lack  of  point-building  section  multipliers, 
but  the  Albuquerque  V.H.F.  Club  came  through 
with  20  logs.  A  goodl}'  number  of  reports  came 
from  North  Carolina  groups,  whose  principal 
complaint  was  that  stations  they  should  have 
been  able  to  work  in  Virginia  and  farther  north 
didn't  turn  their  beams  around  to  the  south  often 
enough. 

Checking  a  contest  of  this  magnitude  is  not 
done  in  an  idle  hour;  it  will  be  some  time  before 
the  final  results  are  known.  But  one  thing  is  sure: 


One  of  the  more  popular  items  of  v.h.f.  gear  described  in  QST  in  the  past  year  was  the  ''One-Package  2-Meter 
Station"  by  Vk  IVLH,  in  the  April,  1954,  issue.  These  pictures  show  an  adaptation  of  the  design  by  \^  2NGN,  whj^ 
followed  the  original  closely  circuitwise  but  modified  the  la>(iut  tn  fit  a  murr  riinimonly-availalili-  ca-e. 


The  8th  V.H.F.  Sweepstakes  provided  a  week  end 
of  competition  that  will  not  soon  be  forgotten. 

Here  and  There  on  the  V.H.F.  Bands 

More  on  tlie  Sejjt.  IStli  fireball:  In  December  QST, 
page  08,  \vc  reiiorted  strange  doings  on  144  Mc.  that 
appeared  to  tie  in  with  the  appearance  of  a  fireball  in  western 
skies  tlie  night  of  Sept.  18th.  At  that  time  we  knew  that 
\V0TJF  had  heard  W5VWU,  and  that  several  New  Me.xico 
stations  had  heard  unidentified  DX,  apparently  reflected 
from  the  region  around  the  fiery  visitor.  In  response  to  our 
request  for  information  on  any  other  reception  of  this  sort, 
\V0VEC,  Lincoln,  Nebr.,  sends  us  the  following: 

At  about  2130  CST,  W0VEC  heard  a  c.w.  station  on  144 
Mc.  say,  "—SO  GA  \V?FAG  DE  W7VMP".  Undoubtedly, 
the  station  being  worked  was  W5FAG.  At  2143,  W5VWU 
was  heard  by  W0VEC  and  called,  following  reception  of  his 
CQ.  The  signal  had  risen  to  a  peak  of  S8  to  9,  in  a  series  of 
bouncing  fades,  and  it  faded  out  in  the  same  way.  The 
entire  period  of  reception  was  about  30  seconds.  The 
W7VMF  signal  was  steadier,  about  SI. 

The  2-meter  reports  from  various  parties  appear  to  span 
a  period  of  half  an  hour  or  more,  yet  reports  of  the  fireball's 
appearance  relate  to  only  a  few  minutes,  at  the  most.  It 
appears  possible  that  tlie  reception  reports  resulted  from  a 
fairly  general  meteor  shower,  of  w  Inch  the  fireball  may  have 
been  merely  one  spectacular  part.  We  suspect  that  quite  a 
bit  more  of  this  sort  of  thing  would  be  observed,  if  2-meter 
activity  were  maintained  regularly  on  the  scale  that  prevails 
during  a  v.h.f.  contest  week  end. 

Here's  a  fellow  who  really  has  had  antenna  trouble! 
\V4CVQ,  Raleigh,  N.  C,  had  just  put  up  24  elements  each 
for  220  and  144,  when  Hurricane  Hazel  dropped  a  tree 
across  his  guy  wires.  All  antennas,  including  a  6-meter 
beam,  a  "d.c.-band  long  wire,"  and  the  above,  toppled 
110  feet  to  the  ground.  Next,  a  32-element  144-Mc.  beam 
was  erected,  and  seven  days  later  a  turkey  flew  into  it. 
(Jake  says  the  array  looked  as  if  the  invader  was  a  bomber!) 
The  latest  in  the  line  of  2-meter  beams  is  a  24-element, 
W2NLY-style  coUinear,  horizontal.  It  works  out  better 
than  the  32-element  for  .lake's  requirements,  as  it  is  less 
critical  as  to  direction. 

This  can  be  important  in  an  area  where  much  searching 
of  the  band  is  required,  and  this  certainly  applies  to  North 
Carolina,  though  things  are  looking  up  there  on  2.  The 
V.H.F.  SS  file  contains  quite  a  batch  of  logs  from  North 
Carolina  entrants,  for  the  first  time.  Several  of  the  boys 
complain  that  they  couldn't  work  out  of  the  state  because 
the  stations  to  the  north  didn't  turn  their  beams  down  that 
way  of  ten  enough. 

W4CVQ  is  another  of  those  fellows  who  is  working 
miracles  with  826s.  His  pair  run  very  easily  at  500  watts 
input  on  voice,  and  have  been  pushed  to  800  watts  input 
without  undue  heating. 

W4DWU,  Falls  Church,  Va.,  thinks  that  all  2-meter  men 
must  use  old  call  books.  He  was  formerly  located  in  St. 
Petersburg,  Fla.,  and  he  still  has  to  spend  quite  a  bit  of 
time  disillusioning  excited  2-meter  ops  who  think  they  have 
just  snagged  a  Florida  station. 

How  consistent  is  communication  over  a  450-mile  path 
on  144  Mc?  Some  idea  can  be  gained  from  results  between 
W8BFQ  and  WIHDQ.  Both  stations  have  good  locations, 
but  the  terrain  in  between  is  very  rough,  all  the  way.  In 
the  period  between  October  25th  and  the  end  of  the  year, 
a  schedule  kept  at  1715  EST  produced  identifiable  signals 
each  way  on  24  tries.  This  figures  out  to  quite  a  bit  better 
than  half  the  time,  when  equipment  troubles  and  inability 
of  one  or  the  other  to  keep  the  skeds  are  included.  Tests 
consisted  of  only  two  minutes  of  transmission  each  way. 
Experience  the  previous  winter,  and  through  last  spring, 
indicated  that  when  5-minute  transmissions  were  made  by 
W8BFQ,  at  least  some  recognizable  signal  could  be  heard 
by  your  conductor  just  about  every  try.  Similar  results,  or 
better,  have  been  achieved  in  nearly  all  parts  of  the  country, 
and  over  paths  that  apjjear  even  more  formidable  than  the 
one  between  West  Kichfield,  Ohio,  and  Canton,  Conn. 

There  is  increasing  interest  in  extended-range  tests  in 
many  (|uartcrs,  as  word  gets  around  that  hops  of  several 
hundred  miles  can  be  worked  regularly  on  144  Mc— i/ 
sufficiently  good  equipment  and  antennas  are  used.  W5FAG, 
Albuquerque,  N.  Mex.,  is  making  nightly  tests  with 
W6WSQ,  W6NLZ,  and  W7LEE  at  2200  MST.  Hub  has  a 
low-noise  converter  and  a  selective  i.f.  system.  His  antenna

is  a  16-element  array,  but  a  64-element  job  is  nearing 
completion,  as  is  a  1-kw.  final  stage.  Activity  and  equipment 
on  432  Mc.  are  improving,  also.  W5s  NSJ  EDK  FJE  and 
FAG  all  have  crystal-controlled  gear  and  low-noise  con- 
verters on  that  band,  too. 

W5VWU,  formerly  of  Albuciuerciue,  has  moved  to  Florida, 
taking  with  him  a  1-kw.  final  and  all  the  other  gear  needed 
to  do  outstanding  work  on  144  Mc.  We  may  get  that  Florida 
activity  yet  —  if  John  doesn't  let  that  climate  get  him  down 
too  soon.  Another  prospect  for  2-meter  DX  tests:  W7LHL, 
Seattle,  Wash.,  is  making  a  winter  project  of  the  construc- 
tion of  a  high-powered  final  stage  and  a  big  horizontal  beam. 

As  2-meter  activity  becomes  more  universal  around  the 
country,  a  closer  tie-in  between  v.h.f.  men  and  the  ARRL 
field  organization  miglit  well  be  made  a  major  objective 
of  SCMs  and  other  ARRL  oflficials.  One  way  that  this  aim 
can  be  served  is  to  arrange  for  more  fre<iuent  and  widespread 
transmission  of  ARRL  Official  Bulletins  on  the  v.h.f.  bands. 
W9USI,  Wilmette,  111.,  transmits  bulletins  on  144  Mc.  as 
regularly  as  possible  at  1930  CST  nightly.  He  runs  through

CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD/9 


Who: 

Well,  the  first  half  of  the  21st  ARRL  Inter- 
national DX  Competition  now  is  history'.  How're 
you  doing?  Hah,  if  you  think  you  goofed,  here 
follow  some  early  and  tragic  DX  Test  flashes 
from  around  the  country.  For  your  1955  Ail- 
American  All-Call- Area  All-Star  DX  Test  line-up, 
Jeeves  nominates: 

Wl  — ,  Orson  A.  Roundalot,  whose  imagination  was  work- 
ing so  well  that  every  number  he  lieard  was  meant  for  him. 
So  far,  best  score  he  ever  (tliought  he)  made. 

W$  — ,  Zeke  N.  Peck,  an  expert  touch-typist,  who  kept 
his  entire  log  on  a  mill  but  didn't  notice  the  ribbon  break 
during  the  first  hour. 

W3  — ,  Watkins  D.  Mallcrhy,  who  spent  the  whole  first 
Test  week  end  tearing  apart  his  factory-built  k\v.  Then 
found  it  had  stopped  working  because  the  XYL  had  kicked 
out  the  wall  plug  while  dusting. 

W4  — ,  Warren  N.  Beelup,  whose  beam  rotator  froze  in 
the  southeast  quadrant  as  the  Test  began.  Came  out  of  the 
first  week  end  with  638  KP4s. 

W5  — ,  Hugh  R.  Buggybud,  w  ho  got  panicky  and  signed 
W4 — /5  instead  of  W5 — /4.  Must  work  his  293  contacts 
all  over  again  to  correct  the  mistake. 

W6  — ,  Don  B.  Sophani,  who  ran  out  of  logsheets  and 
scrap  paper  early  in  the  Test.  Used  his  tool-chest  stock  of 
sandpaper  as  an  emergency  measure  and  wore  out  35  ball- 
point pens. 

W7  — ,  Wayne  E.  Wether,  who  didn't  get  out  worth  a 
dern  after  he  complained  bitterly  to  the  pow-er  company 
about  an  annoying  power  leak.  They  licked  it  by  dropping 
his  lino  level  to  37  volts. 

W8  — ,  Willie  Everbreaihe,  who  sought  to  cash  in  on 
1.8-Mc.  multipliers  and  rushed  out  to  erect  a  long-wire  with 
a  spool  of  No.  8  Copperweld.  Got  it  unwound,  all  right, 
but  it  sprang  back  into  a  roll  from  whicli  he  was  finally 
extricated  eighteen  hours  later. 

W9 — ,  Otis  S.  Terrybcll,  wlio  invited  147  friends  and 
neighbors  over  on  the  week  end  preceding  the  Test,  tliereby 
assuring  subsequent  peace  and  quiet  for  an  all-out  effort. 
As  the  party  guests  arrived,  found  he  had  misread  his  cal- 
endar —  that  was  the  Test  week  end. 

W0  — ,  Preltywcll  Schott,  who  swapped  his  smooth  triple- 
conversion  superhet  for  a  nifty  5-element  rotary  in  the 
interests  of  a  higher  score  this  year.  Sat  down  to  make  a 
killing  as  the  Test  began,  then  committed  suicide;  no 
receiver. 

Our  K,  VE  and  VO  friends  were  having  their 
problems,  too,  but  the  foregoing  brief  grief 
accounts  should  suffice.  No  one  need  despair, 
though,  for  the  last  portion  of  the  Test  is  still  to 
come.  Plenty  of  time  to  boost  that  tally  —  good 
fishin' ! 

What: 

Or  should  we  have  said  good  fission?  That's  just  about 
what  it  takes  to  crack  through  the  Test  pile-ups  around 
some  of  those  gaudy  numbers  leaking  through.  We'll  save 
a  line  or  two  this  month  by  being  a  bit  arbitrary,  using 
Greenwich  Time  exclusively.  And  so  to  press  .  .  .

Not  far  removed  distances Im-,  but  rare  L\  reason  of 
its  small  ham  population,  is  Guadeloupe,  I'.Vi'.I.  A 
burst  of  activity  on  the  part  of  Antoine  Noel,  FG7XB, 
however,  has  put  this  country  in  the  logs  of  many 
happy  amateurs  recently.  Look  closely  at  the  neat  set- 
up above  and  you'll  see  Antoine's  10-watt  transmitter  — 
smaller  than  the  bug  —  in  front  of  the  receiver.  To  the 
delight  of  U.  S.  A.  DXers,  FG7XB  is  currently  plugging

frequent  curse.  Overlong  transmissions  are  nuisances;  let

Net  Know-How 


Improving  Emergency  Communications  Effectiveness 

BY  E.  S.  VAN  DEUSEN,*  W3ECP 


•  In  any  emergency  operation,  the  abil- 
ity to  handle  third-party  traffic  promptly 
and  efficiently  is  a  "must."  W3ECP 
bases  his  recommendations  on  experi- 
ence gained  in  actual  emergency  net 
operations. 


4MATEUR  RADIO  exists  as  a  hobby  because  it 
/\  qualifies  as  a  service. "  ^  The  extent  of  our 
-^  -*-  service  is  limited  by  our  ability.  The 
responsibility  for  furthering  these  abilities  is 
up  to  each  one  of  us.  Experienced  traffic  men 
will  undoubtedly  want  to  add  to  the  following 
observations  and  suggestions  for  improving  opera- 
tions during  an  emergency.  All  hands  will  agree, 
however,  that  almost  all  amateurs  are  extremely 
cooperative  during  a  communications  emergency. 
The  occasional  operator  who  fails  or  refuses  to 
cooperate  during  such  a  period  deserves  short 
shrift,  with  thorough  application  of  the  Wouff- 
Hong  and  the  Rettvsnitch. 

The  operator  who  learns  of  an  emergency  and 
experiences  the  universal  deshe  to  help  may 
unnecessarily  delay  and  complicate  the  flow  of 
traffic,  if  he  has  little  or  no  concept  of  acceptable 
net  procedure.  He  can  best  serve  by  familiarizing 
himself  with  the  situation  by  listening.  Careful 
listening  will  enable  an  operator  to  locate  stations 
and  places  and  to  get  a  good  idea  of  the  over-all 
situation  so  that  he  will  best  know  how  to  help  if 
needed.  A  desire  to  help  through  transmitting  is 
often  more  hindrance  than  help.  If  you're  not 
needed,  silence  is  the  biggest  help!  Eagerness  to 
aid  isn't  an  excuse  for  breaking  into  the  net. 
Proper  procedure  by  the  net  control  should  pro- 
vide opportunity'  periodically  for  additional  sta- 
tions to  report  in.  Only  when  urgent  information 
pertaining  to  the  situation  at  hand  should  be 
made  known  to  the  NCS  is  breaking-in  permis- 
sible. Having  once  reported  into  a  net,  however, 
every  station  should  monitor  the  net  until  he  is 
excused  by  net  control. 

C.  W.  Circuits  Always  Advisable 

In  the  initial  stages  of  an  emergency,  much  may 
depend  on  a  single  station's  ability  to  com- 
municate with  the  unaffected  area  through  use 
of  "flea-power"  c.w.  equipment.  When  com- 
mercial power  fails,  there  may  or  may  not  be 
an  emergency  a.c.  source  available.  On  the  other 
hand,  there  undoubtedly  will  be  auto  storage 
batteries  in  the  area.  Reliance  on  such  primary 

♦Route  Manager,  ARRL;  3711  McKinley  St.  N.W., 
Washington  15,  D.  C. 

'  ARRL  manual.  Emergency  Communications. 


power  sources  requires  the  ready  availability 
of  suitable  vibrator  or  dynamotor  units.  It 
is  obvious  that  c.w.  circuits  should  alwaj's 
be  provided  whenever  and  wherever  possible, 
as  either  the  primary  or  a  secondary  channel 
into  the  affected  area.  No  single  emergency 
situation  has  been  observed  recently  in  which 
the  amateur  effort  could  not  have  been  aided 
materially  by  the  use  of  both  'phone  and  c.w.  In 
several  recent  situations  involving  'phone  emer- 
gency networks,  a  request  for  supplemental  c.w. 
circuits,  or  an  inquiry  regarding  the  possibility 
of  setting  up  such  circuits,  has  been  included  in 
the  operations  shortly  after  the  net  had  been 
organized. 

NCS  Qualifications 

Efficient  management  of  a  net  of  any  sort, 
and  especially  one  working  under  emergencj^ 
conditions,  requires  firm  discipline  by  a  suitable 
net  control  station.  The  NCS  should  be  capable 
of  hearing  and  being  copied  by  a  majority  of  the 
participating  stations.  This  individual  (or  group) 
should  be  thoroughly  familiar  with  control  pro- 
cedures, and  cognizant  of  the  propagation  condi- 
tions that  currently  exist  on  the  band  in  use.  He 
should  be  able  to  think  logically  and  quickly.  Real 
competence  as  a  control  station  can  best  be  at- 
tained by  practical  experience.  Book  learning 
alone  can't  replace  the  knowledge  gained  from 
hours  spent  listening  to  net  operations,  analysis 
of  the  various  situations  which  arise,  and  think- 
ing out  a  better  way  of  handling  them  if  you 
had  been  NCS.  A  frequent  turn  as  NCS  is  an 
invaluable  aid  to  put  your  ideas  into  action  and 
test  your  reactions. 

Net  Discipline  the  Responsibility 
of  the  NCS 

The  supreme  authority  for  priority  and  traffic 
routing  is  the  net  control  station.  In  an  emergency 
the  first  station  becoming  aware  of  the  situation 
should  assume  control  and  retain  it  until  some 
station  better  qualified  (by  virtue  of  experience, 
location,  or  ability  to  contact  a  greater  number  of 
participating  stations)  becomes  available.  When 
a  previously  organized  and  trained  net  is  in- 
volved in  the  incident,  this  is  fairly  simple  to 
accomplish.  Generally  speaking,  the  most  effec- 
tive emergency  networks  are  organized  before 
an  emergency.  In  many  cases,  however,  the  net 
organization  is  evolved  after  the  situation  arises. 
When  this  occurs,  the  station  first  assuming  con- 
trol must  exercise  a  high  degree  of  common  sense 
in  analyzing  facilities  which  become  available, 
and  should  act  quickly  and  without  rancor  in 
turning  over  control  to  a  better  qualified  station 


62 


QST  for 


that  reports  into  the  net.  On  the  other  hand, 
until  such  a  transfer  is  made,  no  other  station 
has  any  right  to  attempt  to  usurp  the  control 
function. 

In  prolonged  operations  involving  the  services 
of  a  succession  of  net  control  stations,  a  complete 
list  of  stations  active  in  the  circuit  at  the  time, 
tlie  areas  they  serve,  and  the  outstanding  traffic, 
if  any,  should  be  given  to  his  successor  by  a  con- 
trol station  who  may  be  leaving  the  net. 

E.xperience  with  established  traffic  nets  has 
conclusively  demonstrated  the  increased  effi- 
ciency which  results  from  the  use  of  at  least  two 
or  three  adjacent  channels.  One  frequency, 
preferably  the  center  frequency,  should  be  us?d 
for  monitoring  b}-  all  stations,  and  transmission 
by  the  net  control.  The  additional  channels  are 
used  as  message-clearing  frequencies.  On  c.w. 
nets,  a  separation  of  5  kc.  is  sufficient;  on  'phone, 
a  wider  dispersion  may  be  desirable. 

When  FCC  declares  a  general  state  of  emer- 
gency', a  10-  or  15-kc.  band  segment  may  be 
designated  exclusively  for  emergencj'  communi- 
cations (Section  12.156,  FCC  Rules  and  Regula- 
tions). With  this  in  mind,  it's  logical  to  start  net 
organization  (under  these  conditions)  on  two  chan- 
nels about  8  kc.  or  so  apart,  and  modify  the 
arrangement  as  the  situation  develops.  During 
such  an  emergency  period,  "guard"  stations 
should  be  assigned  the  specific  job  of  transmitting 
the  FCC  order  and  warding  off  interference. 

Provisions  of  the  Law  Must  Be  Observed 

A  possible  law  violation  (Section  005  of  the 
Communications  Act)  may  inadvertently  occur 
when  press  representatives  are  permitted  to  be 
present  in  the  amateur  "shack"  during  emer- 
gency operations,  especially  when  the  operation 
is  being  handled  by  'phone.  They  should  be 
reminded  that  the  Act  states  that  the  content  of 
the  communications  may  not  be  divulged  to  or 
used  by  any  person  or  persons  except  the  addressee 
or  his  agent.  "Pirating"  of  traffic  is  an  obvious 
violation  of  the  Act.  When  situations  arise  in 
which  a  station  may  be  in  a  position  to  deliver  or 
expedite  certain  traffic  that  has  been  copied  dur- 
ing monitoring,  permission  must  be  obtained 
from  the  transmitting  station  to  accept  the 
message.  Only  when  this  station  releases  its  own 
commitment  does  the  monitorjng  or  requesting 
station  become  authorized  to  handle  the  traffic. 
Under  no  circumstances  is  a  listener  permitted 
by  law  to  put  pirated  traffic  on  another  net;  this 
might  easily  result  in  duplicate  delivery  of  two 
widely  differing  versions  of  one  message,  in  addi- 
tion to  being  a  distinct  violation  of  the  secrecy 
provisions  of  the  Act. 

Accuracy  Is  More  Important  Than   Speed 

Accuracy  first  should  be  the  motto  governing 
all  traffic  operations.  It  is  especially  applicable 
to  an  emergenc}^  situation  when  lives  and  prop- 
erty safety  often  depend  on  the  messages  being 

2  Note  last  sheet  bound  into  ARRL  Logbooks.  —  Ed.

time.  —  Ed. 


handled  over  the  amateur  network.  Accuracy  is 
more  readily  achieved  when  uniform  message 
procedures  are  employed.  Uniformity  of  the  mes- 
sage form  is  very  important.  In  emergency  situa- 
tions, it  is  always  desiral)le  to  include  the  filing 
time  which  is  frequently  omitted  from  the 
message  preambles  routinely  handled  on  normal 
amateur  circuits.  The  use  of  standardized  te.xts 
such  as  the  appropriate  ARL-Xuml^ered  Text  "' 
and  the  "book  message"  method  and,  whenever 
possible,  a  combination  of  both,  can  result  in  the

traffic  when  applied  with  common  sense.  The 
receiving  stations  should  withhold  a  "Roger"

More  elTective  voice  intelligibility  is  obtained 
by  the  use  of  words  instead  of  c.w.  abbreviations. 
(In  military  practice,  accepted  'phone  procedure 
prohibits  the  use  of  coded  c.w.  prosigns  and  re- 
quires the  use  of  the  worded  meaning.)  For  ex- 
ample, the  use  of  QRX  ^  instead  of  "wait"  may 
be  misconstrued  as  QRS  unless  phonetics  are 
used  to  clarify  the  letters  QRS.  You'll  wind  up 
by  saying  the  one  word  "wait"  anyway,  so  use 
it  in  the  first  place  and  you'll  avoid  confusion

securing  "fills"  or  confirmations  often  takes 
longer  than  would  have  been  required  to  clear  the 
entire  message  if  it  were  transmitted  at  a  proper

Three  Stormy  Sisters 

Part  lit  — Hazel 

BY  GEORGE  HART,  WINJM 


COVERING  more  land  area  than  either  of  her 
older  sisters,  Hazel  probably  did  by  far  the 
greatest  amount  of  damage.  We  received 
reports  from  each  section  on  Hazel's  route,  plus 
a  good  man}'  reports  from  sections  on  her  fringes. 
And  this  gal  had  some  fringes.  Although  she 
passed  through  Central  Pennsylvania  and  West- 
ern New  York,  Hazel  produced  8ixt3'-mile-per- 
hour  gales  and  torrents  of  rain  in  many  areas 
not  more  seriouslj'  afflicted. 

On  the  evening  of  October  14th,  Hazel  ap- 
proached the  Carolina  coasts.  The  South  Carolina 
Emergencv  Net  was  alreadj^  in  operation  under 
PAM  W4FFH,  assisted  by  W4HDR  and 
W4HMG.  At  0130  Georgetown  EC  W4ZGP 
assembled  his  AREC  members  W4s  FTN  GIF 
KTI  COA  and  DYP  to  place  W4ZGP/4,  the  club 
emergency  station,  on  the  air.  This  station  was 
manned  throughout  the  night. 

At  0300  W9MQV/4  reported  into  the  net  from 
M3Ttle  Beach,  and  also  remained  on  through  the 
night.  W4LLH  helped  maintain  contact  with  the 
coastal  stations  through  the  night.  Communica- 
tion and  power  lines  began  to  fail  by  0800  Friday 
morning  and  weather  reports  from  W9MQV/4 
and  W4ZGP/4  enabled  the  Weather  Bureau  to 
determine  that  the  hurricane  went  inshore  at 
Murrells  Inlet,  S.  C,  at  1000  Friday. 

Continuous  contact  was  maintained  with  the 
Georgetown  and  M3Ttle  Beach  stations  with  on-

•  Vt  e  asked  for  them,  and  we  got  them 
—  more  reports  on  activities  during 
Hazel  than  Me  could  possihiy  use.  In  this 
second  installment  of  the  hurricane 
story,  >ve  have  tried  to  stick  to  facts  and 
credits  in  condensing  volumes  of  report 
material  into  a  few  ()ST  pages.

the-spot  reports  being  sent  showing  the  extent  of 
the  damage  as  it  happened.  Intercepts  of  ham 
operations  as  provided  by  W4FFH  were  being 
broadcast  over  radio  and  TV  stations  in  Charles- 
ton. W4ULH/mobile  was  sent  from  Florence, 
while  mobiles  W4U0Q  and  W4QRH  were  sent 
from  Charleston.  These  emergency  stations  were 
confronted  with  a  most  serious  situation.  All 
communications  and  power  lines  were  out.  There 
was  urgent  need  for  troops,  blankets,  emer- 
gency rations  and  medical  supplies.  Through 
W4ULH/m  and  W4HDR  in  Columbia,  Myrtle 
Beach  authorities  were  advised  where  rations  and 
blankets  were  available,  and  that  National  Guard 
troops  were  being  ordered  into  the  area.  Shortly 
W4U0Q/m  with  W4ZRH  riding  with  him  re- 
inforced W4ULH/m.  Police  officials  and  reporters 
rode  with  W4ULH/m  to  tie  in  with  police  radio 
and  the  outside  to  conduct  emergency  operations. 
Georgetown  power  failed  about  1000  and  control 
was  shifted  to  W4ZGP/4  from  his  car,  using  a 
long  wire  to  replace  his  mobile  antenna  at  1400. 
Then  mobile  W4s  ZGP  COA  and  KTI  cruised 
Pawle\s  Island  and  near-by  beaches.  The  ama- 
teur mobiles  coordinated  with  other  units  to  pro- 
vide communications  with  damaged  areas. 

On  Friday  W9MQV/4  was  back  on  the  air  bj^ 
1730.  Weather  reports  by  ham  radio  assisted  the 
Weather  Bureau  to  give  an  early  all  clear. 

In  Florence,  EC  W4AUL  had  mobilized  his 
AREC  group  W^s  DXW  TSU  VAM  VOH  ULH 
and  LLH  long  before  the  storm  struck.  W4LLH 
maintained  contact  with  W9MQV/4  all  night 
Thursday.  W4ULH/m  was  dispatched  to  the 
coast  Friday  morning.  W4s  AUL  DXW  TJA  and 
TSU  helped  dispatch  ACL  trains.  On  Saturday 
morning  the  AREC  membership  cards  permitted 
amateur  mobiles  to  cruise  into  restricted  areas  to 
continue  their  work.  Only  those  messages  of  high- 
est urgency  were  accepted  for  delivery.  On  Satur- 
day evening,  W4s  ZGP  DYP  and  FTN  set  up  a 
transmitter  unit  at  Myrtle  Beach  and  operated 
all  night. 

Operations  were  carried  on  for  daj's  after  the 
storm  with  W4FFH  conducting  the  net  almost 
continuouslj',  assisted  by  W4s  HDR  ZIZ  and 
HMG.  W4BNN  provided  contacts  with  Dillon

PAM  W4FFH  logged  168  stations  reporting  to 
assist. 

EC  W4S0D  reports  that  Lumberton  lost 
power  at  1051  Friday,  October  15th,  and  he, 
from  his  mobile  rig,  became  the  only  contact  from 
the  area. 

In  Raleigh,  W4HUW  operated  entirely  on 
emergency  power  from  1330  October  15th  until 
2000  October  16th,  mostly  in  the  Tar  Heel  Emer-

The  Virginia  'Phone  Net  and  the  Old  Do- 
minion Net  combined  forces  on  3835  as  the  Vir- 
ginia Emergency  Net  starting  on  October  14th 
and  operating  continuously  until  the  evening  of 
October  16th.  FCC  declared  3830  to  3840  kc.  a 
clear  frequency  within  1000  miles  of  the  coast.

In  Hampton,  W4AJA  was  on  the  air  from  0800 
on  Saturday  until  the  same  time  Sunday  morning, 
when  c.d.  control  W4RGN  took  over.  W4VYZ 
handled  a  crucial  message  to  Fort  Monroe  via 
W9GWY/m  near  Washington.  The  following  sta- 
tions in  Hampton  participated:  If 4s  AJA  RGN 
MAN/m  VYZ/m  RTZ  QCA/m  ZXL  GZD/m 
JCM.  W4RGN  and  W4QCA  operated  on  emer- 
genc}^  power. 

In  Norfolk,  EC  W4PAK  alerted  the  AREC 
gang  at  1900  on  October  14th,  and  29  mobiles  and 
two  net  control  stations  turned  out.  Participation 
was  on  both  the  VFN  frequency  of  3835  and  the 
local  29.6  Mc.  frequency.  By  1500  on  Friday  the 
winds  had  reached  100  m.p.h.  and  things  started 
to  happen.  Communications  were  handled  for 
the  power  companj',  the  Weather  Bureau,  Civil 
Defense,  and  local  Red  Cross  and  emergency 
traffic  was  being  handled  as  fast  as  the  net  could 
take  care  of  it.  All  transmitting  was  done  with 
auxiliary  power  equipment.  When  the  75-meter 
antenna  blew  down  at  the  control  station, 
W4PWX  and  W4LCW  maintained  communica- 
tion for  Norfolk. 

EC  W3WN  of  Frederick,  Md.,  reports  a  close 
tie-in  with  Frederick  police,  working  with  them 
from  the  time  Hazel  hit  Frederick  (1745,  Oct. 
15th)  until  about  2100.  Mobiles  were  dispatched 
with  policemen  to  points  of  hazard.  The  Fred- 
erick net  mobilized  without  being  alerted.  '^ 

In  the  Washington  area,  W3KZQ,  W3NL,  and 
W3ECP  were  early  on  the  job  getting  the  Wash- 
ington Mobile  Radio  Club  organized  at  the  re- 
quest of  the  D.C.  Chapter,  American  Red  Cross. 
W3WLA  took  over  net  control  on  29,520  kc.  at 
1615  on  October  15th  and  checked  in  mobile 
stations  to  take  part  (almost  100  per  cent). 
W3KZQ  conducted  the  1800  roll  call  on  emer- 
gency power.  W3ECP  maintained  close  contact 
with  the  Red  Cross  during  the  blow.  Stations

The  AREC  of  Washington  County,  Md.,  was 
alerted  by  both  Civil  Defense  and  Red  Cross  and 
by  1415  October  14th  seven  AREC  members  had 
three  fixed  stations  and  five  mobile  units  ready 
for  action.  By  1800,  fourteen  AREC  members 
were  monitoring  3827  as  well  as  assisting  the 
MEPN  and  the  VFN  with  emergency  traffic, 
with  five  mobiles  and  one  portable  power  unit 
on  a  stand-by  basis.  The  alert  was  secured  at

The  Maryland  Emergency  'Phone  Net  was 
active  on  3920  kc.  At  1155  on  the  15th,  the 
emergency  plan  was  put  into  effect.  At  1650,  FCC 
declared  3815-3825  kc.  an  emergency  channel. 
The  frequency  clearance  was  withdrawn  at  2200, 
but  many  members  continued  operating  through- 
out the  night.  The  following  day  operation  con- 
tinued, most  traffic  being  relaj^  of  information 
north  and  south  concerning  the  extent  of  the 
damage.  As  conditions  deteriorated  Saturday 
night,  FCC  gave  voluntary  clearance  on  3820  at 
1800.  The  net  was  official  signed  off  at  2000.

Mobiles  in  Anne  Arundel  County  under  EC 
W3SLG  got  together  as  prearranged  at  1700  on 
the  15th  and  manned  the  control  center,  using 
emergency  power  since  regular  power  was  off. 
Net  Control  W3VPR  (manned  by  W3JKU  and 
W3SLG)  contacted  State  Control  W3W^BP  on 
29.64  Mc.  W3TRG/m  was  assigned  to  handle 
Red  Cross  communication.  W2UQS/m  was  sta- 
tioned at  Edgewater  police  station.  Telephones 


failed  at  the  control  station  at  2000,  and  all  com- 
munications were  handled  on  6  and  10  meters. 
Clearance  from  emergency  was  obtained  at  2200. 
Damage  was  slight.  Other  mobiles  in  the  act:  WSs 
NLX  LHK  VU  NAE  OEJ  TRG  UKO  UQS. 

In  Allegany  County,  amateurs  under  EC 
W3PMQ  installed  six-meter  equipment  at  the 
police  station  and  the  club  room  of  the  Mountain 
Radio  Club  at  the  American  Legion  building.  The 
call  W3YMW  was  used.  The  following  amateurs 
participated:  WSs  ECU  MGO  KMT  UAB  UAC, 
WNSs  YII  YIJ  and  W8GHS. 

The  Radio  Officer  of  Maryland's  Fifteenth 
CD.  District,  W3QLG,  was  called  upon  to  pro- 
vide communications  and  enlisted  the  aid  of  WSs 
FMG  WCW  KLA  and  WN3YLQ,  all  with  mo- 
biles on  two  or  ten  meters.  The  mobiles  went 
into  action  at  1730  October  15th.  Evacuation 
was  their  main  task,  the  mobile  units  being 
placed  at  the  disposal  of  the  c.d.  officer  in  charge. 
All  communications  and  power  were  out  in  the 
area  until  the  following  day.  Mobile  units  were 
released  at  0400  October  16th. 

W3AVL  reports  for  Southern  Maryland  that 
considerable  damage  was  wreaked  by  high  winds 
in  that  area,  after  weather  reports  had  indicated 
that  the  hurricane  would  pass  to  the  west.  Elec- 
tric-power failures  occurred  at  intervals  from 
1100  until  1700  on  the  fifteenth,  at  which  time 
power  in  the  entire  area  was  shut  off,  and  tele- 
phone service  also  was  out.  W3AVL  operated 
with  emergency  power.  On  Saturday  W3AVL/m 
traveled  to  St.  George's  Island  where  information 
on  the  amount  of  damage  to  houses  and  other 
property  was  reported  via  W3PPY. 

In  Cecil  County,  W3VZZ  started  organizing 
the  local  net  at  1430  on  the  15th.  At  1600  his 
power  went  off,  so  his  station  was  set  up  at  the 
fire  house,  with  the  help  of  WN3ZVX  and 
W3TXR.  The  station  was  put  on  the  air,  imme- 
diately reported  into  the  net  and  started  handling 
traffic.  The  county  c.d.  director  was  much  im- 
pressed with  this  operation. 

As  a  result  of  activity  of  Maryland  amateurs 
during  Hazel,  a  letter  was  received  by  State 
Radio  Officer  W3JE  from  Maryland  Governor 
McKeldin  saying,  in  part:  "It  is  gratifying  to  me 
to  know  that  our  State  has  such  a  magnificent 
communications  network  which  can  be  utilized 
in  the  event  of  any  large-scale  disaster.  I  com- 
pliment you  and  your  associates  for  your  out- 
standing organizational  activities  and  hope  that 
my  congratulations  for  a  job  well  done  can  be 
extended  to  j'our  membership." 

On  Friday  night  October  15th  from  1800  to 
2000  Hurricane  Hazel  unleashed  its  furj^  on  Dela- 
ware. W3SQV,  chairman  of  the  local  "Blue  Hen 


66 


QST  for 


Mobile  Group,"  at  about  1700  called  the  Net  on 
29,520  kc.  and  offered  service  to  the  Wilmington 
Red  Cross  and  the  Delaware  State  Police.  Those 
standing  by  were  WSs  FFF  NNK  PCZ  QWR 
QZI  SQV  TDU  TKM  UO  and  W4ANL/3.  The 
group  was  released  by  the  Red  Cross  and  the 
State  Police  at  2130. 

W3BHK  did  a  great  deal  of  relay  and  contact 
work  for  Washington  Red  Cross  during  the  hur- 
ricanes. During  Hazel  alone  he  indicates  60  sent, 
40  received,  33  relays  and  22  patches.  He  op- 
erated 48  V^  hours,  5^2  of  them  on  emergency 
power. 

In  Montgomery  County,  Pa.,  EC  W3CN0 
reports  communication  established  with  state- 
level  key  station  W30JE  at  1920  on  the  15th, 
and  set  up  monitoring  watches  on  28,888  and 
29,493  kc.  between  the  hours  of  1800  and  2100 
EST.  The  following  stations  called  in:  WSs 
TER/m  TWQ  VST.  WSs  HYU  and  IGW  were 
listening.  All  stations  had  mobiles  available  in 
case  of  need.  The  net  was  secured  at  2100  EST. 

York  County  (Pa.)  got  the  brunt  of  the  storm, 
and  by  1500  on  the  15th  power  was  off  in  large 
sections  of  the  county.  W3GES  took  over  as 
Acting  EC  and  took  part  in  the  Pennsylvania 
Fone  Net,  acting  as  NCS  for  a  part  of  the  time. 
Earlier,  W3GES  had  alerted  three  other  local 
amateurs  with  mobiles  and  had  offered  services 
to  the  local  Civil  Defense  and  Red  Cross.  W3GES 
was  assisted  by  W3VNJ  and  W3WWF. 

Hazel  roared  toward  the  Philadelphia  area  in 
the  late  afternoon  of  the  fifteenth.  The  cit}''s  c.d. 
volunteers  were  alerted  and  manned  the  c.d. 
centers,  starting  at  1800.  Members  of  the  Phil- 
Mont  Mobile  Club  checked  in  from  their  radio- 
equipped  cars  and  stood  by  for  assignments.  The 
Fox  Chase  Control  center  lost  power  after  1900, 
but  a  generator  on  a  c.d.  rescue  truck  was  utilized 
to  supply  power.  The  centers  were  allowed  to 
"secure"  at  2145.  A  partial  list  of  participants  as

Luzerne  County  had  some  activity,  reported 
by  EC  W3DUI.  He  got  together  with  W30HX, 
who  had  emergency  power  available,  and  about 
1900  when  power  went  off  operation  commenced 
from  that  station.  The  police  and  c.d.  were  served 
by  amateur  communications.  W3THB  and 
W3PVY  were  also  on  hand  and  two  mobiles  were 
ready. 

The  Pennsylvania  Fone  Net,  under  W3PYF, 
did  an  excellent  statewide  job  during  Hazel. 
W3PYF  asked  W3GES  to  start  organizing  the 


'I'lic  Norlliainpton  County  (Pa.)  AHEC  gang  acti- 
vated the  station  at  c.d.  headquarters  in  Bethlehem 
during  Hurricane  Hazel.  The  station  operates  under 
the  call  W3POX/3  in  the  Delaware  Lcliich  Amateur 
Radio  Net.  Left  to  right  are  W30K,  \V3FQ\  and

net  at  1525  on  the  15th,  while  he  set  up  his 
emergency  power  and  took  over  the  net  at  1600, 
by  which  time  26  Pennsylvania  stations  had 
already  called  in.  QRM  gathered,  too,  and  with 
the  assistance  of  W2JWN,  W3UKF  and  W3BHK 
FCC  was  asked  to  declare  a  clear  channel  which 
they  did  (3850  plus  and  minus  5  kc.)  at  1915.  By 
2000,  21  stations  had  called  in. 

There  was  also  activity  in  the  local  Northamp- 
ton County  (Pa.)  Net  on  29,640  kc.  The  Beth- 
lehem C.D. -Red  Cross  stations  were  activated 
with  W3QBF  at  Red  Cross  and  W3NNT  and 
W3PQX  at  C.D.  headquarters,  both  on  emer- 
gency power.  Contact  was  maintained  with  mo- 
biles in  the  stricken  area  at  all  times  (WSs  NF 
OK  QMH  ELH  and  WlUVE). 

The  New  York  State  Phone  Traffic  and  Emer- 
gency Net  was  in  operation  starting  at  1700 
October  15th  with  K2BY0  as  NCS.  W3s  ZRV 
UNF  JNM  ILI  and  YXE  consecutively  took 
over  NCS  duties,  and  at  2300  Oct.  15th  when 
skip  lengthened,  W8PXF  assumed  net  control, 
and  later  W9VRK.  The  net  was  closed  at  0115. 
About  52  stations  participated. 

In  Broome  County  (N.  Y.)  the  two  meter  net 
was  in  operation  with  W2s  SWF/2  OW  PST/m 
JOJ  FCG  QXX  HJS  UJS  HZP/m  DOM  SDA 
and  K2CWD.  The  Binghamton  area  was  badly 
hit,  and  W2SFW/2  was  set  up  at  the  Binghamton 
Sun  offices  to  receive  reports  of  damage. 

At  about  2000  on  October  15th,  electric  power 
and  half  of  the  telephones  went  out  in  Oswego 
County.  EC  W2ZHU/m,  W2UMI  and  W2FFU 
went  into  action  on  2  meters.  W2UMI  reported 
two  fires  burning  in  Mexico,  N.  Y.  The  AREC 
stood  by  to  assist  in  fire  communications  until 
the  fires  were  brought  under  control  at  2300. 

Four  Oneida  County  stations  reported  in  on 
3925  kc.  about  1730  October  15th  and  remained 
until  0100  Oct.  16th.  Two  meters  was  monitored 
from  1800  the  15th  until  1200  the  16th. 

In  Seneca  County,  local  AREC  mobile  stations 
were  alerted  at  2045.  At  2130  Hazel  struck  the 
area,  commercial  power  went  out  and  many  trees 
went  down.  From  2135  to  0030  the  mobiles 
assisted  in  providing  emergency  communication 
for  the  police,  who  had  no  emergency  power.  At 
2230  until  0030  mobiles  also  provided  additional 
communications  for  the  Sheriff's  Department. 
Participants  were  W^s  YPP  HXK  and  K2s 
BFF  HMY  and  DYA. 

The  Finger  Lakes  2  M(^trr  Xot  was  in  operation 


March  1955 


from  2000  to  2300  Oct.  15th.  Stations  in  this  Net 
included  amateurs  in  Monroe,  Ontario,  Wayne, 
Cavuga  and  Genessee  Counties.  Participants 
were:  W£s  BCL  BLP  CTA  ECM  OWF  QY 
TKY  UXP  VBH  ZHB  ZS  UTH,  K2s  BWK 
CEH  DBB,  KN2IN0. 

In  the  SjTacuse  area,  W2BTB  was  kept  busy 
with  weather  and  radar  reports  to  the  local  Red 
Cross  Chapter  Disaster  Chairman,  and  handling 
a  number  of  welfare  requests  for  Red  Cross' 
Home  Service  Department.  At  Red  Cross  head- 
quarters, W2CRD  was  activated  and  performed 
valuable  service  all  during  the  hurricane. 

Hazel  poured  between  five  and  eight  inches  of 
rainfall  into  the  Toronto  area  within  the  space  of 
a  few  hours,  precipitating  unprecedented  floods. 
More  than  fifty  bridges  and  culverts  were  washed 
out,  and  hundreds  of  homes  near  the  river  were 
washed  away  or  damaged.  The  AREC  plan  of 
listening  on  the  emergency  frequencies  of  3765 
kc.  and  51  Mc.  was  followed. 

Of  the  v.h.f.  group,  VE31Z  was  the  first  to 
become  active,  out  in  his  mobile  at  0730  on  Oc- 
tober 16th.  VE3AIB  joined  him  at  0900,  and 
shortly  thereafter  VE3BQK/m  and  VE3BYY 
came  on.  These  four  set  up  a  v.h.f.  net  on  51 


This  innocent-looking  contraption  is  an  emergency 
generator.  Simple  enough,  but  it  spelled  the  difference 
between  being  on  the  air  and  not  being  on  the  air  during 
Hazel  in  a  great  many  places.  Does  your  AREC  group 
have  one,  ready  to  go  at  a  moment's  notice  if  needed? 
Hazleton  has,  and  this  is  it,  plugging  away  during 
Hurricane  Hazel. 

Mc.  and  advised  the  75  meter  net  control, 
VE3N0,  of  their  availability.  VE3IZ/m  and 
VE3BQK/m  were  dispatched  to  Woodbridge 
while  VE3BYY/m  and  VE3AIB/m  went  to  the 
Weston  area,  both  hard  hit.  VE3DER  operated 
fixed  to  keep  them  in  contact  with  telephones. 
The  next  day  mobiles  wore  dispatched  to  Weston 
to  assist  in  the  search  for  bodies.  The  51  Mc. 
control  station  (VE3AZY/3)  was  moved  from 
CD  headquarters  and  set  up  in  the  Weston  police 
station,  with  VE3DQW  assisting.  From  approxi- 
mately 1300  until  1730,  communication  between 


various  search  parties  and  headquarters  was 
maintained  via  VESs  ARV/m  IZ/m  and  AIB/m. 

This  grim  task  was  not  the  end  of  it  for  the 
Toronto  gang.  Communications  were  out  in  the 
area  for  several  days  after  the  hurricane,  par- 
ticularly in  the  Westmount  area,  and  the  AREC 
was  instrumental  in  providing  communications 
for  emergency  purposes.  As  late  as  October  24th, 
the  Toronto  v.h.f.  group  was  working  with  offi- 
cials in  Westmount,  Etobicoke,  Woodbridge  and 
Pine  Grove,  as  well  as  Toronto.  Mention  should 
be  made  of  the  supplementary  work  of  the  fol- 
lowing: VESs  AIB  ATB  ARV/m  AZY  BJB 
BYY  BYZ  DER  DQW  DHG  IZ  and  UT. 

Low  frequency  groups  were  also  active  in  the 
Toronto  area.  VE3EAM  alerted  VESs  BBM  and 
EAU,  then  took  off  for  Woodbridge.  Arriving  at 
1200,  Bert  set  up  his  equipment  in  the  municipal 
office,  and  the  first  message  he  handled  was  from 
the  maj^or  requesting  troops,  food,  medical  sup- 
plies, etc.  From  then  on  he  handled  a  constant 
stream  of  urgent  traffic  to  VE3BBM  who  relayed 
to  VE3BJV  for  delivery  by  Toronto  telephone. 

Nets  were  also  set  up  and  operative  on  the  ten 
and  75  meter  bands,  under  VE3NG  and  VE3RG 
respectively.  VE3N0  did  an  admirable  job  as 
net  control  on  the  75  meter  net,  and  VE3NG 
turned  in  an  outstanding  performance  on  10. 

The  Hamilton  AREC  group  was  called  in  on 
Sunday  the  17th  to  help  in  the  Woodbridge  area. 
Six  cars  and  a  portable  unit  were  immediately 
dispatched.  They  set  up  immediately  on  arrival 
and  helped  with  communications  for  the  Red 
Cross  and  Fire  Department.  Later,  they  opened 
a  ten  meter  net  to  Toronto.  In  action :  VESs  KM 
DGJ  DRM  AXV  DRI  AGJ  BOW  CJM  EAB 
DHQ  CJ  CC  AYW  and  BV. 

All  in  all,  a  stellar  job  done  by  Ontario  ama- 
teurs, especially  the  gang  in  and  around  Toronto.

The  swirls  of  Hazel's  skirts  produced  havoc 
elsewhere  than  along  the  path  of  her  baleful  eye. 
W2RTE  reports  activity  in  Eastern  New  York 
section  comparable  to  that  in  Carol  and  Edna, 
nets  operating  on  75,  10  and  2  meters.  W2RTE 
himself  had  to  set  up  emergency  power  to  stay 
with  the  net  on  Saturday.  Even  over  in  eastern 
Mass.  the  effects  of  the  hurricane  were  severe 
enough  that  six  members  of  the  Falmouth  Ama- 
teur Radio  Association  formed  a  net  to  maintain 
contact  with  Civil  Defense,  the  Coast  Guard  and 
the  National  Traffic  System.  The  amateurs  who 
turned  out  were  Wis  QLT  LYV  DVS  UXG  and 
TJW  with  the  club  station  WlWNM  as  NCS.

QST  for 


The  six-meter  gang  was  very  active  in  the 
Toronto  area  during  the  hurricane.  This  is 
VE3AIB,  one  of  the  Toronto  ECs,  operating 
equipment  belonging  to  VE3IZ  in  Weston, 
Out.  This  set-up,  from  a  church  location, 
provided  emergency  communications  for 
over  two  days  from  Weston. 


W2ZAI  reports  activity  in  both  Queens  and 
Nassau  Counties,  N.  Y.  In  Queens,  the  ten-meter 
net  was  in  operation  from  2030  on  the  15th  until 
1300  on  the  16th,  with  25  stations  reporting  in. 
Six  members  staj-ed  at  the  Queens  County  Con- 
trol all  night:  WBs  AFA  AKR  ANK  CVU  CJP 
and  ZTX.  Early  Saturday  morning  mobiles 
W2ZTX  and  W2ANK  were  dispatched  to  Rocka- 
way  Beach,  along  with  W2CJP.  Traffic  handled 
was  in  regard  to  flood  damage  and  evacuation. 
The  Nassau  County  AREC  was  alerted  at  1630 
on  October  15th  by  EC  W2FI.  He  set  up  W2FI/2 
at  the  Red  Cross,  and  three  other  stations, 
W2KEB,  W2KFV  and  K2DHC  (operated  by 
W2JKX),  were  activated.  Mobiles  used  both  2 
and  10  meters.  Forty-four  stations  reported  into 
the  net,  three  from  Suffolk  County. 

Although  considerably  west  of  Hazel's  path, 
flooding  occurred  in  the  Ohio  River  Valley. 
Amateur  radio  was  called  into  action  at  Steuben- 
ville  by  the  Red  Cross,  and  three  stations  were 
set  up.  Operators  taking  part  included  WSs  DNQ 
ERR  JNL  SFI  EZC  ZEI  VGK  EZH  and  CHE. 
In  the  Camden,  N.  J.,  area,  two  and  six  meter 
nets  were  activated  by  the  South  Jersej'  Radio 
Association  at  1800  on  the  15th.  W2YRW  was 
NCS  of  the  2-meter  net  from  his  car  at  first. 
Later,  W2PAU  took  control  using  emergenc}^ 
power.  W2TBD  assisted  the  local  police  in  Med- 
ford  and  Medford  Lakes.  W2LY  reported  from 
mobile  that  cross-country  high  lines  were  falling 
near  Route  38,  hampering  vehicular  traffic. 
Others  reporting  in  on  the  two-meter  net  were 
WSs  EGP  JRO  PEN  NFL  VX  ASG  OQN  PTM 
PZX,  K2AFJ  and  KN2s  GYH  GYN  and  JEI. 
K2AJD  was  NCS  of  the  ten-meter  net,  assisted 
by  W2QBH  and  K2BWG.  The  roll  call  produced 
WSs  ABQ  YPQ  CIJ  FTO  CKX  TXP,  K£s 
DWY  BZK,  WSs  AOE/2  OEN  and  HEK.  Many 
of  these  were  mobiles.  Contact  was  maintained 
with  the  Burlington  County  (N.  J.)  net  on  29,560 
kc.  Operation  of  both  nets  continued  from  1800  to 
2200.  W2YRW  reports  that  32  operators  turned 
in  128  man  hours  of  work  in  his  area. 

The  Burlington  County  (N.J.)  Radio  Club  also 
reports  considerable  activity  during  Hazel.  With 
four  mobiles  and  two  fixed  stations,  the  entire 
group  of  six  stations  was  in  operation  during  the 
storm:  W2s  EVR  GOK  JJV  WKI  WUP  and 
ZNB. 

The  RACES  net  of  Conn.  Area  4  was  active 
during  Hurricanes  Carol,  Edna,  and  Hazel.  The 


net  control  station,  WlTIJ,  is  located  in  the 
State  Police  barracks  in  Colchester,  which  is 
equipped  with  auxiliary  power.  The  following 
radio  officers  were  active:  Wis  IWY  YFG  UQV/l 
ZYJ/1  NPB  EBO  KZQ  NPE/1  MHF  and  LF. 
WlPHP  is  radio  officer  for  Area  4. 

The  transcontinental  Relay  Net  again  was 
on  alert  following  the  path  of  Hazel  and  sending 
out  Imlletins  concerning  her  progress,  speed 
and  direction.  The  frequency  of  7042  was  kept 
clear  for  the  bulletins  and  reporting  stations. 
Net  stations,  especially  those  in  Hazel's  path, 
kept  close  touch  with  their  local  weather  bureaus 
both  to  receive  and  give  information.  The  net 
likewise  did  a  most  commendable  job  of  handling 
a  great  deal  of  long  haul  emergency  traffic,  much 
of  it  of  an  official  nature.  Many  of  the  stations 
were  operating  on  emergency  power.  Net  manager 
W3CVE  submits  the  following  list  of  participat- 
ing stations:  Wis  QA  YEJ,  W^s  BO  CGG  EQG

Epilogue 

Many  of  those  who  reported  also  reported  the 
many  lessons  they  learned  in  operating  under 
emergency  conditions  as  hurricane  followed  hur- 
ricane into  some  of  the  most  populated  and 
industrialized  parts  of  our  country.  These  three  ' 
diabolical  visitations,  similar  to  but  more  ex- 
tensive than  the  series  of  tornadoes  we  experi- 
enced in  1952,  have  a  parallel  in  atomic  warfare. 
What  we  amateurs  did  in  the  hurricane  emergen- 
cies wo  must  be  prepared  to  do  in  the  event  of 
nuclear  attack,  multiplied  manifold.  If  the  visits 
of  Carol,  Edna  and  Hazel  can  be  considered  in 
any  way  to  be  good,  then  it  was  because  of  the 
"shot  in  the  arm"  the}'  gave  to  emergency  pre- 
paredness everj^where  they  visited,  and  to  the 
increased  awareness  on  the  part  of  public  offi- 
cials. Civil  Defense  and  otherwise,  of  the  values 
and  potentialities  of  the  radio  amateur.

More  on  FCC  Suspensions.  Two  amateur 
operator  license  suspensions  were  reported  in 
these  columns  last  month  in  QST.  Looking  at 
eleven  other  1954  amateur  operator  license  sus- 
pensions, there  were  some  five  kinds  of  violations 
that  drew  this  type  penalty.  In  each  case  the 
suspension  required  that  the  license  be  turned 
in  to  FCC  and  the  station  not  be  operated  by  any 
person  for  the  specified  period. 

1)  Two  instances,  violations  of  Sec.  12.157  by  using 
"obscene,  indecent  or  profane  language"  on  the  air,  re- 
ceived penalties  of  90  days  (W4ESP),  also  four  years'  sus- 
pension (remainder  of  license  term)  was  invoked  in  the 
case  of  another  amateur  licensee,  now  deceased,  for  wilful- 
ness in  committing  this  violation. 

2)  One  Technician  Licensee,  WIUZZ,  drew  a  90-day 
suspension  for  operating  on  the  144-Mc.  band  contrary  to  his 
license  privileges. 

3)  Three  Novice  (WN0QIY,  WN9ZEV,  KN6B0S)  and 
two  Technician  licensees  (K6AXX,  W6CKW)  received 
suspensions  of  30,  90  days  and  for-remainder-of-license 
term  for  violations  of  one,  or  combinations  of  more-than- 
one,  of  the  following:  use  of  A-3  in  3.8-4  Mc,  or  in  7  Mc. 
(12.23  d-e);  using  call  not  assigned  (12.158);  use  of  un- 
modulated carrier  for  protracted  periods  (12.134);  and  for 
failing  to  keep  a  proper  log  (12.136  b  and  f). 

4)  A  suspension  of  30  days  was  made  in  the  case  of 
WIZE  for  permitting  operation  by  an  unlicensed  person, 
which  is  a  violation  of  Sec.  12.28,  and  Sec.  318  of  the  Act, 
also  for  failure  to  keep  an  accurate  log  (Sec.  12.136)  and 
failing  ability  to  produce  logs  in  the  1-year  period  prior  to 
May  10,  for  FCC  inspection,  a  violation  of  Sec.  12.137. 

5)  WGSAC's  30-day  suspension  was  for  use  of  power  in 
excess  of  1  kw.  (12.131). 

6)  A  suspension  for  remainder  of  license  term  was  ordered 
in  the  case  of  WN9YDZ  for  using  a  frequency  and  call  not 
authorized  a  Novice. 

On  Improving  Message  Handling.  Besides  the 
questions  from  amateurs  newly  interested  in 
this  field  these  days,  some  traffic  netters  are 
urging  steps  for  progressively  improved  results 
.  .  .  such  as  an  increased  use  of  the  service 
message.  Operating  an  Amateur  Radio  Station, 
page  12,  gives  the  low-down  on  such  between- 
station  traffic,  customarily  started  to  get  missing 
information,  or  report  inability  to  deliver,  or 
other  aspects  of  the  operating  service.  Each  year 
for  three  years  there  has  been  a  substantial 
increase  of  interest  in  traffic  handling.  With  the 
trend  continuing  this  year,  we  hope  the  "service 
message"  will  account  for  a  proper  proportion 
of  the  increase,  for  the  great  good  this  can  do. 
Missing  parts  really  should  bo  queried  at  source 
(l)y  originators),  of  course,  so  incomplete  traffic 
n(!ver  gets  started!  However,  we  suggest  making 
it  common  practice  to  use  the  service  message  to 
get  the  missing  parts  when  they  are  not  put  in 
by  the  originator.  Undeliverable  messages  should 
bo  reported  by  message  to  originating  stations  in 
all  eases.  But  let's  stop  at  source,  by  reasonable 
interrogation,  crijjpled  traffic  that  has  vital  sec-

tions  missing  from  the  preamble  or  an  insufficient 
address.  Any  service  message  sent  not  only  counts 
in  one's  total  but  is  a  direct  contribution  to  our 
amateur  ability  to  handle  record  traffic  in  a 
praiseworthy  manner. 

Edison  Award  Winner  Acclaimed.  Ben 
Hamilton,  W6VFT,  ARRL  SEC,  of  La  Mesa, 
Calif.,  was  honored  February  10th  at  a  Washing- 
ton, D.  C,  public  dinner  presentation  of  the 
1954  Edison  Radio  Amateur  Award.  This  was 
in  view  of  his  outstanding  civil  defense  communi- 
cations, organizational  and  educational  work  in 
San  Diego  County,  Calif.  There  were  special 
citations  for  the  notable  services  of  Carl  Theis, 
W8BKH,  in  constructing  equipment  for  mis- 
sionaries resulting  in  saving  lives,  and  for  the 
excellent  amateur  radio  communications  estab- 
lished and  maintained  by  Carter  Rogers,  W8NCS, 
in  the  West  Virginia  flash  flood.  Besides  proclaim- 
ing Mr.  Hamilton  award  winner,  the  judges  also 
adopted  a  resolution  commending  the  merito- 
rious services  of  more  than  800  amateurs  helping 
with  emergency  communications  in  the  triple 
hurricane  emergency.  Besides  the  special  honor 
to  Mr.  Hamilton,  we  regard  this  acclamation  as 
a  great  honor  and  recognition  of  importance  of 
civil  defense  amateur  radio  organizational  work. 

Observations  of  a  Novice  working  in  the 
Round-up  are  the  subject  of  a  letter  from 
KN2nW.  He  writes,  "We  can't  all  be  perfect  but 
calling  attention  to  some  of  our  operating  errors 
in  QST  should  help  in  improvement.  I  found 
myself  going  over  my  speed  and  having  to  correct 
errors,  also  e.xtending  my  calls  too  long  and 
repeating  too  much  of  my  text.  Then  there  is  the 
man  who  has  never  heard  a  WlAW  tape  or  so  it 
seems  .  .  .  when  he  calls  CQ  you  can  only 
guess  what  it  means.  Another  has  a  note  like 
water  bubbling  in  a  pipe  so  it's  a  wonder  he  gets 
any  answers  outside  of  FCC  citations.  My  pet 
peeve  is  a  WN  using  a  bug  with  jerky  spacing; 
the  dits  get  away  from  him.  .  .  ."  All  amateurs 
will  agree  that  a  bug  has  no  place  on  the  air  until 
it  has  been  mastered  in  practice  of?  the  air! 
Sending  in  step  with  our  WlAW  tapes  and  with 
hand  key  is  still  a  fine  way  to  cultivate  sending 
accuracy  and  judgment  in  "spacing."  All  ama- 
teurs will  do  well  to  monitor  their  transmitters. 
Use  the  receiver  with  antenna  off,  if  no  monitor 
is  available,  to  check  that  note.  It  is  our  guess 
that  all  operators  in  taking  part  in  the  January 
Novice  Round-up  got  useful  practice  in  self- 
correction  of  common  difficulties  like  poor  choice 
of  speed  and  calling  times.  Only  by  practice  doe.s 
one  develop  into  a  good  operator  who  can  get

most  enjoyment  and  the  best  results  with  his 
gear.  A  specific  objective  such  as  the  N-R  calls 
for  powers  of  coordination  beyond  casual  work, 
and  builds  operating  know-how.

end  (Mar.  25th-27th)  coming  up  in  March  in  the 
current  ARRL  International  DX  Competition. 
If  you  weren't  all  set  for  the  February  period  it's 
not  too  late  to  try  your  hand  at  DX  in  March; 
and  if  you  got  a  start  in  February  you  can  very 
well  extend  your  score  in  March  or  maybe  grab 
off  some  of  the  new  countries  that  will  be  in 
there!  See  the  announcement  in  January  QST 
if  you  need  details.  All  scores  and  reports  will  be 
welcomed  by  ARRL. 

Good  luck,  and  in  making  out  your  QSLs 
always  be  sure  they  are  sufficiently  complete  in 
information.  The  date,  the  band,  the  mode,  the 
state  (for  amateurs  working  for  WAS),  the  report 
for  'phone  or  c.w.  and  the  fraternal  spirit  they 
convey  are  all  part  of  the  great  tradition  guar- 
anteed by  your  signature,  as  the  man  behind  the 
key  or  mike.  —  F.E.H.

MEET  THE  SCMS 

Washington's  SCM,  Victor  S.  Gish,  W7FIX,  first  became 
interested  in  amateur  radio  in  1912,  at  which  time  he  did 
some  spark  coil  experimental  work,  but  it  wasn't  until 
1935  that  he  obtained  his  first  license. 

The  rigs  currently  in  use  at  W7FIX's  basement  shack 
include:  (1)  6L6  crystal,  807  buffer,  p.j).  T-40s  final  for 
80-   and   40-meter   work;    (2)    6AG7    VFO,    6AG7   buffer. 


813  final  for  80  meters;  and  (3)  1626  crystal,  1625  final  for^ 
160   meters.   Receiving  equipment  consists  of   a   BC-312, 
an  SX-71,  an  SX-25,  an  EC-1,  and  Command  receivers. 

SCM  Gish  is  assistant  director  of  the  Nortliwestern 
Division,  as  well  as  Route  Manager,  Official  Relay  Station, 
and  Official  Observer,  and  is  a  member  of  the  North  Seattle 
Amateur  Radio  Club.  In  addition  he  manages  to  find  time 
to  enjoy  participation  in  the  CD  Parties.  His  copying  speed 
is  35  w.p.m.,  for  which  he  has  been  awarded  a  Code  Pro- 
ficiency certificate.  Rag  Chewers  Club  and  A-1  Operator 
Club  certificates  also  have  been  issued  to  him. 

At  the  age  of  17  Vic  joined  the  Navy  and  in  1917-1918 
installed  the  first  bridge-controlled  radio  on  the  USS 
Pennsylvania.  In  1941  he  was  physically  retired,  was  re- 
called the  next  year  to  be  placed  in  charge  of  the  wire  room 
of  the  13th  Naval  District,  and  was  released  in  1946. 

Vic's  hobbies  include  printing  PAN  News  and  reading 
westerns  and  historical  novels.  His  pet  sports  are  baseball 
and  football.

Each  year  at  aljout  this  tinio  tlie  ofTicers  and  directors  of 
the  League  prepare  annual  reports  to  tlie  Board  of  Directors 
outlining  activities  and  progress  during  the  previous  year. 
This  gives  the  Board  members  sometliing  to  think  about 
(as  if  they  didn't  liave  enougli  worries  already!)  prior  to  the 
annual  meeting.  Naturally,  the  officers'  reports  are  longer 
and  more  comprehensive,  since  they  have  to  do  with  the 
conduct  of  League  affairs  on  a  nation-wide  day-t'>  day  basis. 

In  the  Communications  Manager's  annual  r>port,  there 
is  always  a  section  devoted  to  the  status  of  the  AREC  and 
emergency  work  in  general.  Tliat  means  us.  We  do  not  use 
the  pronoun  "us"  in  the  editorial  sense,  refeninj;  to  the 
writer.  It  means  you  and  me,  all  of  us  who  are  lesponsible 
for  the  affairs  and  activities  of  the  Amateur  Radio  Emer- 
gencj'  Corps  throughout  the  year  and  throughout  the  nation 
Your  NEC  is  not  in  any  sense  the  director  of  amateur  emer- 
gency affairs;  he  is  the  coordinator  of  those  affairs,  the  point 
of  consolidation  at  which  the  things  you  do  are  pinpointed 
and  moulded  into  a  presentable  nation-wide  picture.  He  is 
entirely  and  utterly  dependent  on  you  for  the  size  and  shape 
and  completeness  of  that  picture.  At  annual  report  time,  it 
is  his  job  to  paint  the  picture,  your  job  to  supply  the  paint. 
Naturally,  if  you  supply  only  a  small  amount  of  paint,  the 
picture  is  really  not  a  picture  at  all,  but  only  a  sketch. 

That's  the  way  it  has  been  in  past  years.  The  EC  Annual 
Report  form  goes  out  with  the  SET  Bulletin.  About  ten  per 
cent  of  the  ECs  return  them.  This  year,  we  sent  out  a  re- 
minder card,  and  it  paid  off  to  the  extent  of  bringing  in  a 
dozen  or  so  additional  reports.  A  good  many  ECs  replied 
that  they  had  nothing  to  report  of  any  consequence.  Others 
had  mislaid  the  report  forms.  Some  reported  informally,  not 
even  knowing  that  there  was  a  report  form.  Most  of  them 
never  replied  to  the  reminder  card  just  as  they  had  never 
replied  to  the  initial  receipt  of  tlie  form  in  the  first  place; 
probably  an  extension  of  the  developing  negative  reaction 
to  recaipt  of  any  printed  third-class  mail. 

We  have  said  before  and  we'll  say  again  that  we  would 
rather  have  a  good,  active  EC  who  never  reports  than  an 
inactive  one  who  reports  regularly  (usually,  that  he  is  in- 
active). First  things  come  first;  if  energetic  pursuit  of  your 
function  as  EC  does  not  leave  the  five  minutes  or  so  per 
month  for  a  Form  5  report  or  the  half  hour  or  so  per  year 
for  an  annual  report,  then  let  it  be  so.  The  report  of  statistics 
is  not  all  important,  but  it  is  quite  important  just  the  same. 

Perhaps  next  year,  instead  of  burying  the  EC  Annual 
Report  form  in  the  SET  Bulletin,  we'll  make  it  the  subject 
of  a  special,  later  mailing.  Will  that  help?  It's  too  late  now

On  M.xrch  29,  19.54,  a  severe  snowstorm  hit  the  Buffalo 
area,  causing  traffic  jams  and  people  to  be  late  or  unable 
to  get  home.  Mobilers  W2HS1,  K2DVD  and  W2LYE,  by 
contacting  other  amateurs,  were  not  only  able  to  get  word 
to  their  own  families  of  their  pro  licamcnt.  but  performed 
the  same  service  for  a  great  number  of  other  motorists 
caught  in  the  same  traffic  jams.  Taking  turns  as  NCS  for  the 
improvised  net  were  WSs  CMS  and  OV.l.  Stations  taking 
traffic  included  Wis  MYN  NZA  UXS  POM  PRI  E/l'X

A  tornado  liit  the  ^lacon,  Georgia,  area  on  March  13th, 
1951,  taking  off  the  roof  of  W'4SPD's  house  and  all  his 
transmitting  antennas.  After  settling  his  family,  he  went  to 
the  home  of  EC  W4LXE  and  found  Stubby  already  on  the 
air  using  emergency  power,  with  four  mobiles  already  out 
searching  for  stricken  areas.  The  mobiles  relayed  needs  of 
victims  back  to  W4LXE,  from  whence  they  were  telephoned 
to  the  Red  Cross  (W4SPD  is  chairman  of  the  Macon  Red 
Cross  Disaster  Communications  Committee).  Mobiles  were 
manned  by  ll'^s  LQW  ,JMW  LXE  and  ZYA.  W^s  UJC 
UMN  and  SPD  manned  the  kilowatt  at  W4LXE.  W4TAZ 
operated  his  fixed  station  for  relay  work.  Although  fortu- 
nately all  areas  were  available  to  mobile  units  this  time,  the 
Macon  Amateur  Radio  Club  has  begun  construction  of  a 
number  of  two-meter  hand-carried  units.  Others  active  in 
this  emergency  were  W4s  DZL  TED  YVVW  and  KL7AQJ/4. 


While  traveling  along  Skyline  Boulevard  about  forty 
miles  south  of  San  Francisco,  and  participating  in  the  Sky- 
riders  Net,  W6WD  noticed  fresh  skid  marks  on  the  highway. 
Slowing  down  and  investigating,  he  discovered  that  a  car 
liad  crashed  25  feet  off  the  highway  into  a  ditch  —  out  of 
sight  of  the  road  —  and  that  two  ladies  and  an  elderly 
gentleman  were  injured.  W6WD  broke  into  the  net  ahead 
of  turn  and  apprised  them  of  the  situation.  K6EER  tele- 
phoned the  San  Mateo  County  sheriff  and  a  radio  ambulance 
and  patrol  car  were  dispatched.  While  the  ambulance  was 
en  route,  WOWD  administered  first  aid  to  the  injured 
parties.  WGANK  was  net  control,  and  the  entire  net  re- 
mained on  the  air  until  everything  was  well  under  control. 
Thanks  to  K6EER  for  reporting  this  incident. 

This  is  precisely  the  sort  of  thing  we  were  talking  about 
in  August  QST  last  year  (p.  66).  K6EER  suggests  that 
amateur  mobiles  equip  themselves  with  first-aid  kits  in 
order  to  be  the  more  useful  in  such  a  contingency. 


A  tornado  struck  the  town  of  Wellington,  Ala.,  with  prac- 
tically no  warning  at  about  1330  on  Sunday,  Dec.  5,  1954,

QST  for 


causing  30  casualties  and  several  hundred  thousand  dollars 
worth  of  damage.  Amateurs  in  Anniston  were  alerted  by 
W4BCU,  who  notified  W4SUF  and  W4GCV.  Organization 
began  at  1430.  SUF/m,  in  contact  with  GCV,  was  unable 
to  reach  the  stricken  area  because  of  poor  visibility.  W4PJB, 
with  W4V0Q  riding  with  him,  was  the  first  to  reach  Wel- 
lington, after  having  difficulty  getting  through  Highway 
Patrol  roadblocks.  Services  were  offered  to  the  Highway 
Patrol,  Red  Cross  and  Civil  Defense.  W4s  UHA  and  OAO 
undertook  to  establish  contacts  on  75  meters.  The  Alabama 
Emergency  Net  (AENP)  was  alerted  and  put  on  stand-by. 
Contact  between  the  two  nets,  one  on  75  and  the  other  on 
10,  was  maintained  by  landline.  W4DZF/m  was  dispatched 
to  a  hilltop  to  establish  contact  with  both  P.JB/m  in  Annis- 
ton and  with  control  station  W4GCV.  From  this  point  he 
acted  as  a  relay  station  during  the  entire  emergency,  and 
also  succeeded  in  establishing  contact  with  W4EBD  in 
Birmingham.  At  1600  W4s  SVM/m  and  SUF/m  joined 
W4P.JB/m  in  Wellington  and  operation  settled  down  to 
routine.  All  traffic  originating  in  Wellington  was  relayed  by 
W4DZF/m  to  W4GCV  in  Anniston.  W4YCO  was  assisting 
W4DZF/m.  The  Red  Cross  furnished  casualty  lists  which 
were  relayed  to  Wellington,  Birmingham  and  Gadsden. 
W4s  OZK  and  PAC/m  operated  from  Padoden.  Mobiles 
remained  at  the  Wellington  site  until  about  midnight,  at 
which  time  they  were  released.  Traffic  was  handled  for  the 
Governor,  Red  Cross,  Anniston  T'ire  Dept.,  .\nniston  Police 
Dept.,  State  Highway  Patrol,  National  Guard,  the  Birming- 
ham News,  the  Anniston  Star,  Civil  Air  Patrol  and  Civil 
Defense.

plans.  The  network  operated  on  ten  meters,  and  tie-in  was 
effected  with  state  c.d.  networks  operating  on  75  meters. 
EC  W3LMM  reports  that  the  distribution  of  all  stations  in 
the  individual  zones  was  excellent.  In  one  zone  he  de- 
liberately refrained  from  notifying  the  control  station  of 
the  yellow  alert,  just  to  see  what  would  happen.  A  mobile 
unit  took  over  as  zone  control  prior  to  the  red  alert,  and 
immediately  following  the  all-clear  the  regular  zone  control 
station  was  active.  WSLMM  (who  is  also  radio  officer  for 
R.\CES)  feels  that  the  drill  was  most  successful;  participa- 
tion increased  100  per  cent  over  a  similar  drill  held  last  June. 


Tennessee  civil  defense  conducted  a  statewide  alert  on 
November  7th  last  year,  centered  around  Knoxvillc,  which 
was  "bombed."  SEC  W4RRV  reports  that  the  AREC  gang 
aroimd  the  state  did  a  good  job  for  amateur  radio.  Cities 
represented  included  Knoxville,  Chattanooga,  Nashville, 
Memphis,  Cookville  and  Oak  Ridge.  The  Tennessee  C.W. 
Net  was  also  active  and  received  high  praise  from  c.d.  offi- 
cials. In  fact,  one  newspaper  quoted  the  Chattanooga  Area 
Deputy  Civil  Defense  Director  as  saying  that  the  local 
amateurs  "can  offer  the  best  commimication  service  in  that 
field  of  anywhere  I  have  ever  seen.  I  am  amazed  at  their 
service."  Nice  going,  Tennessee  gang. 

Twelve  SECs  reported  activities  for  November,  195t. 
Total  AREC  membership  represented  was  4330.  None  of  the 
twelve  was  new  to  the  reported  list,  so  the  total  remains  at 
29  sections.  We  aLso  had  twelve  reports  for  November  last 
year.  Sections  reporting:  Los  Angeles,  Western  New  York. 
New  York  City-Long  Island,  Eastern  Florida,  Wisconsin, 
South  Dakota,  Montana,  Western  Florida,  San  Joaquin 
Valley,  Georgia,  Colorado,  Alabama. 


Last  December  the  Maryland  Civil  Defense  Control 
Center  was  honored  by  an  inspection  visit  from  Marv- 
land's  Governor  McKeldin.  The  RACES  installation 
came  in  for  its  share  of  interest,  as  shown  in  the  picture. 
The  operators,  left  lo  right,  are  WSQIF  and  W3IF\^  .

TRAINING  AIDS 

If  you're  a  member  of  an  ARRL-affiliated  club  and  have 
not  seen  the  films  available  to  your  group,  ask  your  club 
secretary  to  write  the  Communications  Department  for  a 
list  of  current  training  aids.  At  present  they  include  30 
films,  13  film  strips,  two  slide  collections  and  ten  different 
quizzes.  The  demand  is  high  but  items  available  now  can 
furnish  your  club  with  many  a  lively  and  educational 
evening.

TRAFFIC  TOPICS 

W0KXL  brinps  up  the  matter  of  the  need  for  certain  end- 
ing signals  in  traffic  net  operation.  On  QKS  (Kansas  Section 
Net)  they  follow  a  procedure  by  means  of  which  any  listen- 
ing station  wlio  just  happens  to  turn  on  his  receiver  or  get 
tuned  in  can  tell  by  the  ending  signal  used  by  the  NCS 
whether  or  not  the  way  is  open  for  him  to  QNI. 

Perhaps  we  traffic  men  ought  to  adopt  some  sort  of  stand- 
ard procedure  in  ending  signals,  since  the  signals  adopted 
by  ARRL  after  the  war  were  adopted  primarily  with  the 
needs  of  the  DX  man  in  mind.  We  hear  KN  used  quite  often 
in  casual  contact  these  davs.  The  ending  signal  we  hear  most 
of  the  time,  however,  is  AR  K,  which  signifies  nothing  except 
that  the  transmitting  station  is  ending  a  transmission.  Ac- 
cording to  the  ARRL  code  (Operating  Aid  No.  2),  it  would 
mean  the  station  has  just  called  another  station  and  wishes 
any  station  to  answer  him.  Not  very  logical. 

W0KXL  points  out  that  ending  signals  should  be  used  in 
net  operation,  otherwise  the  receiving  station  has  no  way 
of  knowing  when  the  transmission  is  ended.  Perhaps  he  has 
a  point.  Most  of  us  have  run  into  this  difficulty  in  our  c.w. 
traffic  nets.  Here  are  a  few  examples  of  some  ending  signals 
that  we  need : 

1)  Acknowledge  instructions. 

2)  Reply  desired  by  stations  concerned  only. 

3)  Do  not  reply,  or  no  reply  necessary. 

4)  End  of  QTC  list  (used  by  station  reporting  into  net). 

5)  Stations  may  report  into  net. 

We're  collecting  suggestions  on  the  above.  Anybody  have 
any? 

Miscellaneous  Net  Reports:  (1)  The  Transcontinental 
Relay  Net  had  a  traffic  count  of  1622  in  31  sessions,  aver- 
aging 52  per  session;  five  stations  participated.  (2)  The 
Transcontinental  'Phone  Net  reports  14  stations  handling 
827  messages.  (3)  North  Texas-Oklahoma  Net  handled  531 
messages  in  31  sessions,  854  check-ins.  (4)  The  Early  Bird 
Transcontinental  'Phone  Net  handled  1304  messages  in 
December,  making  their  total  9519  for  the  year  1954;  they 
count  each  message  only  once,  no  matter  how  many  times 
relayed. 

United  Trunk  Lines  announces  that  its  directors  for  1955 
are  W3WV,  WODDE  and  W9TT.  Each  division  averaged 
close  to  1300  messages  per  month  in  1954. 

Those  of  you  who  prefer  'phone  and  don't  mind  climbing 
out  of  the  hay  at  a  rather  early  hour  might  like  to  have  a 
whirl  with  the  Early  Bird  Transcontinental  Net.  This  net 
was  formed  back  in  the  late  Forties.  It  started  as  a  rag-chew 
group,  but  W6BPT  kept  reporting  in  with  traffic,  and  event- 
ually it  became  a  traffic  net  primarily.  It  was  officially  un- 
veiled as  a  net  on  December  5,  1949,  meeting  three  times 
per  week  on  3860  kc.  The  net  now  meets  daily  at  (yawn  I) 
0445  CST  under  the  tutelage  of  W0BVL,  who  says  their 
slogan  is  "To  get  your  traffic  delivered,  put  it  on  the  Early 
Bird.  They  always  come  through." 

Another  transcontinental  net  which  is  trying  to  get 
started  is  the  Transcontinental  C.W.  Net  (TCWN). 
W4BMY  is  doing  the  ramrodding  on  this  one,  and  trying 
to  do  on  c.w.  what  the  Early  Bird  Net  is  trying  to  do  on 
'phone  —  take  advantage  of  early  morning  conditions  to 
get  that  traffic  through.  TCWN  meets  at  0500  EST  on  3690, 
Monday  through  Saturday.  W4BMY  says  that  his  greatest 
ambition  is  to  get  a  QNI  from  every  state  in  the  union  some 
morning. 

W4UWA  reports  a  Christmas  Overflow  Net  operating 
on  3.525  kc.  daily  at  0600  CST  to  handle  overflow  traffic 
during  the  Christmas  season.  This  net  met  11  times,  han- 
dled 149  messages.  It  was  open  to  all  comers,  and  had  rep- 
resentation from  the  following  states:  Tenn.,  111.,  Conn., 
N.  Y.,  Ind.,  Ga.,  N.  J.,  Nebr.,  Pa.,  Vt.  and  Mich.  W4UWA 
suggests  a  regular  NTS  overflow  net  to  operate  in  the  morn- 
ings to  handle  traffic  left  over  from  the  previous  night's 
operation. 

National  Traffic  Syalem.  We  quote  a  short  but  pertinent 
paragraph  from  a  bulletin  by  WGZRJ,  manager  of  the  Cen- 
tral Valley  Net  (NTS  section-level,  San  .Joaquin  Valley  and 
Sacramento  Valley  Sections):  "There  are  three  main  cate- 
gories of  c.w.  traffic  men:  the  iron  man,  the  one-night-a- 


week  man  and  the  occasional  check-in.  .  .  .  Whatever  type 
you  feel  you  are,  we  would  like  you  to  know  that  there  is  a 
place  in  NTS  and  CVN  for  you.  Without  iron  men,  long- 
haul  work  would  slow  down.  Without  many  fellows  who  will 
take  one  or  two  nights  a  week  as  NCS  and  be  there  on  those 
nights,  our  nets  would  soon  start  missing  sessions.  But  with- 
out the  large  amount  of  stations  who  check  in  only  once  in  a 
while  we  would  not  have  enough  stations  to  have  a  net  each 
night.  Everyone  is  needed;  everyone  is  welcome." 

Our  sentiments  exactly.  NTS  is  not  a  system  designed  for 
one  group  or  one  type  of  operator;  it  is  designed  for  all  who 
wish  to  participate.  The  only  requirement  in  participation 
is  this:  remember  that  NTS  has  all  types  of  operators.  If 
the  presence  of  types  different  from  you  (faster,  slower, 
diff'erent  modes,  differing  opinions,  etc.)  irks  you,  it  is  not 
the  fault  of  NTS.  We  don't  work  by  ourselves;  we  work  to- 
gether. We  hope  you  will  accept  this  principle,  because  it  is 
one  most  necessary  for  success,  in  any  organization.

We  continue  to  topple  records.  December  traffic  on  NTS 
topped  all  previous  records,  the  nearest  being  last  year's 
14,833.  Net  sessions  increased  from  last  year's  607,  resulting 
in  the  decrease  in  the  average-per-session  noted. 

Net  notes:  "Skip"  played  havoc  with  IRN  in  December. 
W30NB  would  like  to  have  someone  volunteer  to  take  over 
3RN.  RN5  has  been  handling  a  record-breaking  amount  of 
traffic,  and  W40GG  has  issued  several  fine  RN5  Bulletins; 
representation  from  Southern  Texas  is  badly  needed. 
VE7ASR  reports  bad  conditions  greatly  hampered  RN7 
operations  during  December,  and  NCS  often  fail  to  report; 
representation  needed  from  Saskatchewan  and  Alaska. 
ten's  early  session  (1700  CST)  handles  much  more  traffic 
than  either  of  the  others.  VE3GI  reports  a  new  net,  the 
Northland  Net,  now  represented  on  TRN  by  VE3AVS. 
Four  out  of  six  regions  had  perfect  attendance  on  EAN 
during  December.  W9JUJ  is  still  looking  for  Saturday  night 
NCS  for  CAN.  PAN  certificates  have  been  issued  to 
K6BGM  and  W7APF. 

Transcontinental  Corps:  All  three  TCC  Directors  are 
struggling  to  keep  the  TCC  roster  full  in  the  face  of  con- 
stant turnover  brought  about  by  failure  of  some  stations 
to  make  contact  with  their  counterpart  schedules.  Erratic 
conditions  have  not  helped  any.  In  the  Eastern  Area  there 
are  some  vacancies  which  can  be  filled  by  application  to 
Eastern  Area  Director  W8UPB.  Stations  that  can  make 
contact  with  the  West  Coast  regularly  are  needed.  Being 
able  to  operate  rather  late  hours  would  be  helpful,  too.  In 
the  Central  Area,  W0SCA  and  W0BDR  are  running  the 
TCC  schedules  almost  singlelianded.  Out  in  the  Pacific 
Area,  W()HC  has  had  his  hands  full  trying  to  keep  vacancies 
filled.  Honorable  mention  goes  to  W6A1)V,  W6VIIM  and

BRIEFS 


Mr.  W.  K.  Neville,  jr..  Racing  Chairman,  First  Inter- 
national Cup  Regatta,  staged  October  2nd  and  3rd  at 
Elizabeth  City,  N.  C,  highly  eoninieiuls  the  Tidewater 
Mobile  Radio  Club  (Norfolk,  Va.)  for  their  part  in  furni.sli- 
ing  coinnuinications  during  the  event.  A  number  of  mes- 
sages were  handled  between  the  committee  boat,  the  U.  S. 
Coast  Guard,  the  Pasquotank  River  Yacht  Club,  and  the 
various  pits  and  places  of  importance.  Those  participating 
included  W4s  Y'VG  RGZ  MLD  ZKA  OGX  PAK  IPA  SVT 
DHZ  LCW  RRA  ULL  PWX  FOU  ZCY^  SY'O  JZQ  IND, 
W6T0R  and  \V9GLR. 


A  description  of  the  12- watt  Field  Day  transmitter  at 
W2NLI/2  (Dec.  QST,  page  46)  ended  up  like  this:  "The 
complete  station,  except  for  batteries,  was  placed  on  a  20 
by  36  foot  operating  table,  with  room  to  spare."  As  W0SGG 
points  out,  it  just  shows  what  careful  planning  and  minia- 
ture components  can  produce!

SELECTABLE 
SIDEBAND 
RECEIVERS 


^c 


s 


ORGAARD*  and  McLaughlin**  each  have 
developed  practical  methods  of  switchable  side 
band  selection  for  receivers.  Norgaard's  is  the 
phasing  type  and  McLaughlin's  employs  the  prin- 
ciple of  side  band  selection  by  changing  the  fre- 
quency of  the  conversion  oscillator. 


INGE  both  of  these  methods  have  certain  electrical  merits,  we  at  Halli- 
crafters  have  spent  many  engineering  man  hours  carefully  evaluating  the  two 
systems  for  incorporation  of  the  better  features  of  each  into  our  products. 


<w, 


ITH  a  receiver  having  poor  selectance  ratio  in  the  i.f.  system,  i.e.  poor 
nose  to  skirt  ratio,  the  phasing  scheme  has  some  merit  as  it  can  be  easily 
attached  as  an  outboard  device.  It  may  improve  unwanted  side  band  rejec- 
tion by  as  much  as  35  db;  but  this  value  is  hard  to  hold  in  production  and 
from  a  more  practical  standpoint  20  to  25  db.  is  realistic. 


^. 


F  the  two  systems  are  compared  on  a  cost  basis  for  incorporation  in  a 
new  receiver,  the  phasing  method  docs  not  appear  attractive  as  better  side 
band  rejection  can  be  obtained  at  less  cost  with  good  tuned  circuits. 


c^. 


'ODERN  receivers  of  better  design  from  $250.00  up  are  dual  conversion 
primarily  to  reduce  image  responses.  Dual  conversion  also  makes  practical 
50  kc.  i.f.  systems  with  excellent  selectance  ratio  that  can  further  be  readily 
adjusted  for  various  degrees  of  bandwidth***.  It  has  been  known  for  many 
years  that  the  choice  of  conversion  oscillator  frequency  will  invert  the  side 
bands  at  the  i.f.  frequencies.  However,  McLaughlin  was  the  first  to  apply 
this  principle  for  side  band  selection  when  using  an  i.f.  system  adjusted  to 
pass  only  one  side  band. 


<w, 


ITH  a  highly  selective  dual  conversion  receiver  like  the  SX-96  wherein 
the  i.f.  pass  band  can  be  reduced  to  pass  only  one  side  band,  it  becomes  very 
simple  to  add  effective  side  band  selection  by  choice  of  dual  conversion 
frequencies.  As  the  first  i.f.  is  1650  kc.  and  the  second  50  kc,  the  second  con- 
version oscillator  may  be  either  1700  kc.  or  1600  kc.  Thus,  if  we  switch  in 
the  1600  kc.  we  pass  the  lower  side  band,  and  if  we  switch  to  1700  kc.  we 
pass  the  upper  side  band. 


^, 


'y  the  addition  of  only  a  quartz  crystal,  some  switch  contacts  and  half  of 
a  dual  triode,  Hallicrafters  is  able  to  provide  you  with  good,  effective, 
selectable  side  band  feature  at  a  nominal  cost.

75A-4 
RECEIVER 


The    75A-4    offers    passband 
tuning,  AVC  for  Single  Side- 
band reception,  a  bridged  T 
rejection  notch  filter,  a  crys- 
tal calibrator  circuit,  separate 
detectors  for  double  or  single  sideband  signals,  a  new  noise 
limiter  circuit  that  works  equally  well  on  SSB,  AM  or  CW, 
and    mounting   provision    for    three    separate    Mechanical 
Filters.  Retained  are  the  time-proven  features  of  the  earlier 
75A    series   —   double-conversion,    crystal-controlled    first 
injection  oscillator  for  high  stability  and  good  image  re- 
jection; permeability  tuned,  sealed  master  oscillator  with 
accurate  dial  calibration  and  long-term  stability,  and  Me- 
chanical Filters  in  the  IF  circuits  for  maximum  selectivity. 


32W-1 
EXCITER 


Designed  to  meet  the  require- 
ments of  the  most  discrimi- 
nating Amateur  whether  he 
operates  SSB,  AM  or  CW,  the 
32W-I  Exciter  has  sufficient 
output  power  to  drive  a  high- 
level  power  amplifier  stage, 
and  together  with  the  75A-4 
Receiver  provides  the  basic 
needs  for  a  completely  engin- 
eered Amateur  radio  installation.  Special  features  of  the 
32W-I  are  dual  conversion,  a  permeability  tuned,  hermeti- 
cally sealed  VFO,  a  Single  Sideband  generator  using  the

PROUDLY  ANNOUNCES 
NEW  STANDARD 
in  AM,CW  and  SSB  OPERATION 

It  took  Collins  to  produce  the  first  really  new  Amateur  communication 
system,  designed  expressly  for  Single  Sideband  as  well  as  AM  and  CW 
operation.  Collins  new  75A-4  Receiver/ 32 W-1   Exciter  or  75A-4 
Receiver/KWS-l  Transmitter  combinations  are  designed  for  the  most 
exacting  Amateur.     Engineering-wise,  the  equipment  meets  the  high 
standards  Collins  has  set  for  military  and  commercial  equipment.  Price-wise, 
the  Amateur  will  get  more  for  his  money  than  ever  before.  See  your 
nearest  Collins  distributor  for  your  brochure. 


KWS-1 
TRANSMITTER 

Collins  engineering  plus  extensive  on- 
the-air  tests  account  for  the  KWS-1 
Transmitter's  reliability  and  optimum 
performance  in  SSB,  AM  and  CW 
operation.  The  exciter  and  RF  power 
amplifier  are  housed  in  a  single  receiver 
size  cabinet.  The  Collins  367 A-1  linear 
RF  power  amplifier  uses  two  4Xl50A's 
in  class  AB  operation.  RF  feedback  is 
employed  to  improve  the  linearity  char- 
acteristics of  the  power  amplifier.  The 
KWS-1  incorporates  circuit  application 
and  components  which  have  been 
proved  in  preceding  Collins  equipment; 
to  note  a  few,  the  70E  VFO,  the  Pi-L 
output  network,  extremely  accurate 
VFO  dial  and  the  Collins  Mechanical 
Filters.  To  meet  the  Amateur's  future 
desire  for  power  increase,  Collins 
32W-I  Exciter  can  be  modified  to  a 
KWS-1   at  the   factory.

THE  HQ-MO-X .  * . 


^says  W4VPU 

After  trying  out  his  new  Hammarlund  HQ-140-X  receiver,  Harry  H.  Harris,  Jr., 
of  Charlottesville,  Va.,  W4VPU  commented,  "This  is  truly  a  Ham's  dream." 

Creating  'dream'  equipment  for  hams  is  the  Hammarlund  goal.  How  well  this  goal 
has  been  achieved  is  proven  by  the  enthusiastic  comments  received  from  satisfied 
Hams.  They  appreciate  the  little  extras  in  design,  circuitry  and  construction  built 
into  every  Hammarlund  product. 

For  example,  the  HQ-140-X — the  amateur  receiver  built  to  professional  standards 
— is  rated  XFB  by  Hams  everywhere  because  of  its — 

FREQUENCY  STABILITY  -  less  than  .01%  frequency  drift  after 
warmup  anywhere  from  540  Kc.  to  31  Mc. 

EXTREME  SELECTIVITY  —  sharp  signal  separation  even  in  the  most 
crowded  bands. 

LOW  NOISE  LEVEL  -  a  noise  limiter  that  really  works. 

RUGGED  CONSTRUCTION  —  built  for  easy  use  for  many  years. 

The  HQ-140-X  is  available  either  as  a  cabinet  model  or  for  rack  mounting.  For 
complete  details,  write  to  The  Hammarlund  Manufacturing  Co.,  Inc.,  460  West

ANTENNA  COUPLER 

KIT 

The  new  Heathkit  An- 
tenna   Coupler    Model 
AC-1   was  specifically 
designed  to  operate  with 
the  Heathkit  Amateur 
Transmitter  and  will 
operate  with  any  trans- 
mitter not  exceeding  75 
watts  RF  input  power. 
Rugged  design  has  resulted 
in  a  sturdy,   well  shielded 
unit  featuring  a  copper  plat- 
ed chassis  and  shield  com- 
partment. Coaxial  52  ohm 
receptacle  on  the  rear 
of  the  chassis  connects 
to  a  three  section  Pi-  type  low  pass 
filter  with  a  cut-off  frequency  of  36  Mc. 
Tuning  network  consists  of  a  variable 
capacitance  and  tapped  inductance  in 
an    impedance    matching    unit. 
Capacity  coupled  neon  lamp 
serves  as  a  tuning  indicator 
and  will  also  provide  a 
rough    indication 
of  power  output.

WFK.  Prospective  lianis  in  the  area  are  invited  to  attend 
these  classes  at  the  club  rooms  in  the  Irvinston  Community 
Bldg.  HXP  is  working  on  RACKS  projents.  K2CHI  is 
experimenting  on  new  antennas.  K2B\VQ  has  received  his 
second  M.\RS  citation  for  exceptional  parti 'ipation  for 
the  month  of  November.  His  dau^liter  Barbara,  K2CLC 
(.\.\2CLC),  age  16,  became  the  youngest  M.\RS  member  in 
the  U.  S.  on  her  birthday  Dec.  9th.  Barbara  and  her  dad 
now  become  the  first  fatlier/daughter  team  to  be  registered 
in  M.\RS  work.  E.\S  has  been  away  from  the  home  QTH 
for  tlie  past  two  months  in  connction  with  iiis  work  with 
United  .\ir  Lines  in  tlie  communications  field.  NIY  has 
received  BERT.\  certificate.  HXU  is  having  his  troubles 
with  TVI.  VYB  was  home  on  leave  over  the  holidays. 
KBO  has  been  laid  up  in  the  hospital  for  some  time.  We 
all  wish  you  a  speedy  recovery,  OM.  K2GBP  is  building 
a  new  base  station  now  that  tlie  mobile  transmitter  is  in 
good  sliape.  K2EK0  and  GRU  are  busy  chasing  DX.  BRC  is 
on  low  power  on  20  meters  while  the  new  ri[!:  is  being  built. 
The  Windblowers  VHF  Society  held  a  hobby  party  at  tlie 
home  of  NUL.  K2IiDQ  is  a  new  00.  K2DS\V  is  temporarily 
QRL  because  of  attending  school  at  RC.-^.  However,  during 
the  holidavs  he  had  a  few  minutes  spare  time  and  ran  up  a 
traflic  total  of  411.  K2G.\S  is  a  new  ORS.  K2LUN  made 
BPL  for  the  first  time.  KN2,J0M  has  moved  to  North  Bruns- 
wick. K2B.\Y  confesses  he  never  should  have  monkeyed 
with  his  sky  wire.  As  a  result  his  heaters  have  not  been 
warm  since  Nov.  17th.  K2BWQ  has  added  a  new  tape  re- 
corder to  his  station.  The  Livingston  Amateur  Radio  Club 
is  sponsoring  a  building  program  on  s.s.b.  exciters.  Much 
credit  to  the  promotion  of  s.s.b.  activity  witliin  the  club  is 
due  4CCU  (ex-2N,JR)  and  2ICA.  The  s.s.b.  group  shortly 
will  conduct  an  on-the-air  net  on  75  meters.  Currently 
active  on  s.s.b.  are  BWN,  CCF,  COT,  GBT,  ICA,  IHD, 
NRQ,  and  ORX.  .\nnie,  the  YL  operator  at  K2ICE,  has 
acquired  the  name  of  "Hurricane  •A.nnie."  Thus  stemmed 
the  new  Hurricane  Net  in  Monmouth  County,  which  meets 
nightly,  with  .\nnie  at  tlie  helm,  on  144  Mc.  K2HNA  is 
heard  on  the  air  from  K2UHE's  QTH.  ENM  is  the  proud 
possessor  of  a  new  4-2.50A  all-band  final.  NIE  has  a  unique 
onini-directional  144-Mc.  beam.  This  all  happened  when 
the  brake  failed  on  the  Gordon  Rotator.  We  think  the  beam 
still  is  spinning  atop  tlie  100-ft.  tower.  FC  is  heard  regularly 
on  144  ^Ic.  with  his  new  Gonset.  OUS  is  mobile  on  144  Mc. 
all  over  the  county.  Tune  in  any  time  and  you  will  hear  him

llawmj-yN^yjLS  equipment 

Here   af   Harvey-Wells,   we    make   communications 
systems  for  military  and  commercial  applications, 
and  we  believe  that  Hams  too,  want  ttieir  stations 
complete  in  every  respect.  That's  the  basic  thinking 
behind    this    new   equipment    we    ere    introducing. 
The  tremendous  success  of  our  TBS-50  Bandmaster 
has  been   due   in   part  to  the  fact  that  it  can   be 
put    on    the    air    quickly    and    efficiently    because 
it   is    a    complete    "package"    with    no    additional 
equipment  necessary. 

Our    new   T-90    Bandmaster  Transmitter   is   also   a 
complete    "package".    It    can    be    on    the    air  five 
minutes  after  you  bring  it  home  if  you  so  desire, 
just    plug    in    the    power    supply    and    connect  the 
antenna.    Our    new     R-9    Bandmaster    Receiver,   in 
its    matching    case,   becomes    an    integral    part   by 
simply  connecting  the  antenna  to  the  T-90. 

For  fixed   station  operation,  we  offer  the  APS-90 
A.C.    Power  Supply   in    a   cabinet  to   match.    (Jus> 
connect   to    11 5V  A.C,   plug   the   output   cable   in 
the   rear   of  the  T-90   and  you  are  ready  to  go.) 
The   R-9   Bandmaster   Receiver  has   a   built-in  A.C. 
supply.  For  mobile  operation  we  have  two  vibrator 
power  supplies,   the   VPS-  T90  for  the  transmitter, 
and   the   VPS-R9   for   the   receiver.   Both   are   con- 
vertible for  6  or  12  V  operation. 


VPS-T90 
Mobile     Power     Supply 


Speakers  for  either  fixed  or  mobile  operation  ore 
matched    electrically    and    physically   to    the    R-9 
Bandmaster  Receiver  to  complete  the  system.  This 
new  Bandmaster  Series  is  a  complete  system,  en- 
gineered for  fixed,   mobile  or  portable  operation 
—  a  system  which  has  beauty  as  well  as  efficiency. 
It's  well  worth  waiting  for. 

P.S.  We  are  still  making  the  world-famous  TBS-50  too!

2  element  rotary  beams  for

.'',    iciMi^ 


Designing  and  producing  an  effective  shortened 
beam,  such  as  the  GONSET  Bantam,  requires 
skillful  engineering  and  adequate  measuring 
equipment. ..not  intuition 

There  are  certain  "Musts".  The  wholly  outstand- 
ing performance  of  the  great  many  Bantams  in 
use  today  is  attributable  to  many  things: 


(1)  The  very  high  "Q"  coils  used  in  parisitic  and  driven  elements.  Silver 
plated,  copper  tubing,  self-supporting.  .  .secured  only  at  the  ends  with  high- 
est grodeceramic  insulators.  Observe  that  thesecoils  ore  of  ample  diameter, 
that  no  phenolic  or  ceramic  form  is  used.  For  this  reason  the  GONSET 
Bantam  is  unaffected  by  weather.  COMPARE    these   inductors. 

(2)  The  Bow-tie  elements  which  provide  additional  antenna  surface  area, 
semi-broadbonding.  VSWR  therefore  remains  at  reasonable  limits  within  a 
given  phone  or  C.W.  band.  .  does  not  immediately  soar  as  you  move  fre- 
quency. COMPARE  these  elements. 

(3)  The  effective  link-coupled  line-to-antenna  system  permitting  use  of  52 
ohm  coax  line.  .  .providing  excellent  line  match  and  low  SWR.  .  .symmetry 
in  the  form  of  o  balanced  antenna  pattern.  The  link  is  "stubbed"  for  re- 
actance cancellation. 

(4)  GONSET  does  not  publish  goin  figures  on  the  Bantom  since  these  ore 
meaningless  unless  the  reference  is  clearly  and  cleanly  tied  down  so  that 
everyone  is  talking  about  the  some  thing.  Hundreds  of  tests  conducted  under 
carefully  controlled  conditions  do  indicate  that  the  losses  in  the  Bantam 
have  been  reduced  to  a  point  where  performance,  including  gain  and  F.B.R. 
approaches  that  of  a  full-length  beam.  .  IN  ALL  KINDS  OF  WEATHER! 

These  are  sound  reasons,  theoretically  correct,  readily  verified.  They  ace 
the  reasons  why  you  should  select  o  GONSET  Bantam  for  I  5  and/or  20  if 
lack  of  space.  .  .and  a  desire  for  DX.  .  .is  your  problem.

The  crysfol  oscillating  on  Its  fundomentol  mode  should  be  used  in  circuits  where  the  drive  level  Is 
limited  to  10  mllliwotts  below  10,000  KC  and  to  five  milliwatts  between  10,000  KC  and  15,000  KC. 
A  circuit  meeting  these  requirements  is  shown  above.  The  circuit  will  operate  from  2,000  KC  to  15,000 
KC  end  limit  the  drive  level  to  5  milliwotts.  By  making  capacitor  CI  variable  the  crystol  may  be' ad- 
justed to  exact  frequency. 

The  correct  load  capacitance  of  the  oscillator  is  extremely  important  in  operotion  of  the  crystal,  if 
the    frequency    of    oscillation    is    to    be    within    tolerance    for    which    the    crystal    was    manufactured. 

To  reproduce  32  mmf  precisely,  lead  lengths  end  position  must  be  token  into  account.  Capacitors 
CI  ond  C2,  together  with  tube  and  wiring  capacitance  determine  the  frequency.  Tuned  circut  C3 — L3 
may  be  tuned  to  the  fundomentol  or  a  harmonic.

The  first  zephyr  of  spring  gives  us  the  tingles  to  get 
on  wheels  and  shift  into  high  gear.  Naturally,  we 
take  our  fellow  hams  along  with  us  via  a  honey  of  a 
mohile  rig  just  installed  in  our  car.  If  you're  plan- 
ning an  active  mobile  season,  stop  by  and  see  our 
vehicle  with  a  new  outfit  that  has  some  features 
you'll  find  interesting.  All  you  need  is  the  car — we 
have  everything  else:  dynamotors,  filters,  receivers, 
converters,  noise  clippers,  squelches,  mounts,  load- 
ing coils,  relays,  cable  and  mikes.  While  we  like  the 
Gonset  job  featured  below,  we  have  lots  of  other 
rigs  to  suit  your  own  ideas  on  mobile  radio.

JOHNSON  "MATCHBOX" 
ANTENNA  COUPLER 


BANDSWITCHING— 

for  greater  flexibility 
RECEIVER  MATCHING— 

for  improved  receiver  performance 
EFFICIENT  POWER  TRANSFER  — 

from  transmitter  to  antenna 

Bandswitching  on  80,  40,  20,  15  and 
11-10  meters,  the  compact  and  self-contained 
"Matchbox"  performs  ail  transmission  line 
matching  and  switching  functions  required 
in  medium  power  amateur  stations.  Its 
revolutionary  circuit  design  does  away 
with  the  annoying   use  of  "plug-in"  coils 
and  completely  eliminates  "load-tapping," 
necessary  in  other  antenna  couplers. 

Almost  an  infinite  variety  of  antennas  in 
the  3.5  to  30  mc.  range  can  be  loaded  with 
the  "Matchbox".  Balanced  antennas  from 
25  to  1200  ohms  resistance  con  be  matched, 
while  unbalanced,  or  single  wire  antennas 
within  the  range  of  25  to  3000  ohms 
resistance  can  be  successfully  loaded.  In 
addition,  the  "Matchbox"  will  tune  out 
large  amounts  of  reactance. 

Nominal  input  impedance  is  52  ohms-may 
be  used  with  any  transmitter  having  250 
watts  maximum  power  input,  and  a  PA  plate 
voltage  not  exceeding  1000  volts.  Tuning 
and   loading   is   easily  accomplished   with  two 
convenient  front  panel  controls — al 
connectors  located  at  the  rear  of  the  unit. 

Attractively  finished  in  maroon  and  grey — 
supplied  OS  an  assembled,  wired,  and 
pre-tested  unit.  Complete  operating 
instructions  included.  Dimensions:  9Vi"  wide, 
10  1/2"  deep,  7"  high.  Weight 
approximately  6  pounds.

When  you  rebuild,  see  how  many  of  these  Los 
Gatos  favorites  will  fit  your  new  circuitry.  Or, 
use  them  when  re-tubing. 

You  may  be  surprised,  and  you'll  certainly  be 
pleased  with  the  additional  nine-plus  lives  you'll 
get  from  these  carefully-made  electron  tubes. 

Ask  for  them  at  your  jobber.  If  he  doesn't  have 
them,  he  can  get  them  for  you  —  overnight  in

Diablo  Club's  Party  was  outstanding  and  unusual  in  that  it

Grotto  9,  Fisherman's  Wharf,  with  a  good  show  of  hams. 
The  Tamalpais  Radio  Club  now  holds  its  monthly  meetings 
at  Novato.  The  Marin  County  Radio  Club  had  a  large 
group  show  up  for  the  season's  dinner  held  at  El  Verano. 
The  Young  Ladies  Radio  Club  of  SF  prepared  and  served 
the  food  for  the  SF  Radio  Club  Party.  The  29er8  lost  an- 
other of  its  group,  K6ALF,  to  Uncle  Sam's  Navy.  The 
Humboldt  Radio  Club  members  were  all  on  the  alert  during 
the  big  shake.  K6FKI  was  in  town  mobile  when  it  happened 
and  contacted  GL,  in  Crescent  City,  who  was  first  to  give 
the  news  to  the  Crescent  City  broadcasting  station.  Both 
Eureka  stations  were  off  because  of  power  shortage.  K6DVV, 
W6CNG,  and  BME  all  gave  reports  to  VRG,  in  Oakland,  to 
give  to  the  Oakland  Tribune.  CNG  and  ULF  held  a  cir- 
cuit for  a  time  for  emergency  railroad  traffic  but  none  was 
required.  However,  many  messages  were  handled  because  of 
overcrowded  telephone  lines.  The  Club  held  its  Christmas 
Party  in  lieu  of  its  regular  meeting  and  reports  a  fine  time 
was  had  by  the  group.  AEY  let  the  stove  in  his  ham  shack 
get  overheated  so  now  he  has  a  hole  through  the  roof.  OPL 
received  lots  of  help  erecting  his  V-37  antenna  on  Dec.  5th. 
ATO,  BON,  GGV,  GQA,  GTY,  HST,  OCZ,  OST,  TLN, 
TMF,  and  K6CWS  all  helped  and  report  the  best  antenna- 
raising  feed  ever  held.  ZYI  and  PW  died  within  a  few  days 
of  each  other  during  the  holiday  season.  CBE  reports  that 
he  is  going  low  power  and  is  building  a  40-watt  rig.  YC  has 
been  handling  traffic  from  Japan,  usually  on  Sun.  SWP  has 
been  having  trouble,  high  noise  level  is  wrecking  his  recep- 
tion. Congratulations  to  QMO  on  the  BPL  total  for  Decem- 
ber. ACN  reports  that  the  Bill  for  the  ham  license  plates 
renewal  was  introduced  on  the  legislature  floor  the  first  day 
of  the  new  session  at  Sacramento.  GHI  is  new  representative 
for  the  HAMS  at  the  Central  California  Council  meetings. 
PHT  has  a  new  TV  and  radio  store  in  San  Francisco.  Lots 
of  luck  and  success  in  your  new  venture  —  "CYN's  TV  & 
Radio  Shop."  A  local  amateur  made  the  headlines  in  the 
San  Francisco  newspapers  and  radio  broadcasts  on  Dec.  5th. 
He  was  driving  on  a  very  lonely  road  down  the  country 
shortly  after  a  car  went  into  the  ditch  and  trapped  three 
people.  By  means  of  his  mobile  rig  he  was  able  to  bring  help 
to  them  very  quickly.  WD,  Arthur  Hart,  certainly  let  the 
people  know  of  the  good  deeds  amateurs  can  do.  Local 
papers  gave  Arthur  a  real  nice  write-up.  Traffic:  W6QM0

SEC:  MMT.  RMs:  KQD  and  KHQ.  PAM:  lUF.  The  state- 
wide driU  was  a  success,  with  stations  from  all  over  the 
State  reporting  to  net  control  with  members  of  the  legis- 
lature in  attendance.  AEE  handled  the  net  control,  assisted 
by  WIR  and  MMT.  Our  bill  has  been  introduced  and  has 
been  turned  over  to  the  transportation  committee  for  ac- 
tion. We  must  now  contact  the  members  of  that  group  in 
order  to  keep  them  reminded  of  our  needs.  Also  all  must 
write  their  legislators  so  tliat  they  won't  forget  us  when  it 
comes  time  to  vote  on  the  bill.  If  you  need  more  copies  of 
the  bill,  contact  IC  and  he  will  send  them  to  you.  lUF  made 
BPL  with  102  originations.  EKQ  reports  that  the  CSSN  is 
doing  find  and  a  new  ham  in  Littleton  is  WN0WNJ.  The 
Hi-Noon  Net  handled  437  pieces  of  traffic  in  21  sessions. 
HOP  has  a  new  rig  running  500  watts  on  c.w.  Congratula-

tion with  ARRL.  New  officers  are  MMP,  pres. ;  Muriel 
Schwarz,  vice-pres. ;  Ray  Wilhelm,  secy.  We  all  want  to 
give  the  MARS  stations  in  the  State  a  vote  of  thanks  for 
the  fine  way  that  they  are  working  with  our  amateur  groups. 
They  have  brought  our  traffic  totals  up  to  a  very  respectable 
figure  and  can  always  be  counted  upon  to  help  us  whenever 
we  need  it.  Traffic:  K0FDX  4821,  WBB  2529,  W0KQD

pushed  into  a  rebuilding  program  since  receiving  a  new  6-ft. 
rack  for  Christmas.  BLE  still  is  commuting  from  Salt  Lake 
to  Denver,  but  says  shck  roads  and  mobile  operation  do  not 
fit  together  too  well.  SP  has  nearly  forsaken  low-frequency 
contacts  for  2  meters  —  not  nearly  as  much  QRM  on  2

LOS  ANGELES  — SCM,  Howard  C.  Bellman,  W6YVJ 
—  QJW,  our  SEC,  calls  to  our  attention  the  fact  that  more 
than  14()0  have  signed  up  in  AREC  in  the  section  but  that 
this  figure  should  be  near  5000  to  handle  emergencies 
properly.  Howard  points  out  that  we  need  top  c.w.  and 
'phone  operators  to  man  the  control  centers.  HKD,  Asst. 
SEC  and  EC  for  San  Bernardino  (also  Radio  Officer  for 
Region  8  RACES),  reports  that  the  Hq.  is  set  up  under  the

GROUNDED 
GRID 


PL-6569  is  a  new  high-mu  triode,  de- 
signed especially  for  grounded  -  grid 
amplifiers.  It  is  THE  choice  for  a  1-KW 
amplifier  to  follow  a  "100-watt"  trans- 
mitter. 

Its  high  amplification  factor  (mur=45) 
and  its  high  perveance  mean  a  power 
gain  of  ten  or  more.  More  than  800 
watts  output,  with  only  75  watts  drive! 
PL-6569  is  conservatively  rated  at  250 
watts  plate  dissipation.  Its  low  plate-to- 
filament  capacitance  (0.10;a/xf)  makes 
for  real  stability  as  a  grounded-grid 
amplifier.

Asst.  SCM:  Ew-ing  Canady,  5GIQ.  SEC:  KY.  RM:  GVS. 
PAMs:  PML,  SVR,  and  ROZ.  Message  traffic  has  been 
much  increased  by  the  hohdays  as  shown  by  this  month's 
traffic  report.  Sincere  regret  is  felt  at  the  passing  of  Old- 
Timer  EZK  at  Enid  who  did  much  to  promote  amateur 
radio.  The  position  of  call  letters  in  the  alphabet  is  no 
longer  any  indication  of  the  age  of  the  license  since  the 
necessity  of  reissuance.  The  ACARC  has  issued  a  manual 
of  procedure  for  c.w.  operators  which  is  available  on  request 
and  is  well  worth  while.  CXM  had  a  nice  write-up  and  pic- 
ture in  the  Enid  Morning  News  as  the  State's  only  YL  EC. 
About  half  of  the  77  counties  in  the  State  now  have  ECs 
but  KY  is  asking  for  eligible  apphcants  for  the  others.  The 
Enid  .Annual  Dinner  and  Hamfest  had  103  registrations,  74 
of  them  licensed.  Among  those  present  were  the  SCM,  SEC, 
RM,  two  PAMs,  and  the  local  c.d.  director.  GIQ  was  MC. 
The  North  Fork  Amateur  Radio  Club  has  set  the  date  for 
its  annual  affair  as  May  21-22.  Many  thanks  to  those  send-

states  and  hopes  to  get  WAS  before  he  gets  his  General 
Class  license.  FJF  has  been  doing  very  nicely  with  a  new  kw. 
John  Henry  Kerby,  IH,  has  passed  the  Novice  Class  exam

BRITISH  COLUMBIA  —  SCM,  Peter  Mclntyre, 
VE7JT  —  Last  month  there  was  no  column  because  of  the

two  who  took  the  time  to  write  after  reading  the  last 
published  column,  namely  6MJ  and  7AKD,  who  both 
touched  on  the  lack  of  old-time  ham  spirit.  US  was  the 
guest  speaker  at  the  V.\RC  meeting  where  he  gave  an 
excellent  talk  on  s.s.b.  which  was  well  received.  Wilf 
reports  that  VE7s  ABU,  AKA,  AKN,  ALW,  BV,  TV,

there  are  10  phase  shift  networks  and  5  slicers  floating

been  having  a  rough  time  with  band  conditions  very  poor, 
QRM  from  VE4s,  5s,  6s  and  other  sorts  of  sundry  un-

SASKATCHEWAN  — SCM,  Harold  R.  Horn,  VE5HR 
—  DR  attended  tlie  "Communications  Planning  Course" 
held  at  Arnprior,  Ontario,  Civil  Defense  College,  and 
reports  that  much  information  was  gained  and  many 
ideas  were  exchanged  on  ways  to  put  communications  to 
good  use  during  an  emergency.  A  good  number  of  amateurs 
attended.  CX  reports  that  EB  was  married  on  Dec.  7th, 
with  JG,  BO,  RU,  EB,  and  their  XYLs  in  attendance. 
RU  worked  45  countries  the  past  summer  with  his  80 
watts  and  a  two-element  vertical  on  his  trailer.  Ex-5JS 
now  is  7IW  at  Kelowna.  PW  works  21  Mc.  and  likes  that 
band.  BG  has  a  new  Viking  Ranger.  RG  is  back  on  75 
meters  after  being  QRT  for  a  long  time.  MX  is  heard  on 
14  and  3.5  Mc.  with  his  Viking.  LM  is  now  located  at 
Saskatoon  and  BC  at  Swift  Current.  AT  was  the  only 
VE  west  of  Ontario  to  report  during  the  B.E.R.U.  Contest. 
BZ  is  a  new  OBS  and  can  be  heard  on  3740  kc.  at  1800 
hours  MST  Tue.,  Thurs.,  and  Sat.  Because  of  poor  band 
conditions  the  'phone  net  has  been  practically  extinct  but 
it  is  hoped  that  members  will  be  on  the  watch  for  any 
traffic  when  the  band  is  open.  Traffic:  VE5GX  4.

controlling  oscillator  by  factors  of  more  than  10. 
Suitable  low-frequency  crystals,  including  those 
operating  at  450  kc,  and  which  should  be  as 
useful  as  those  already  mentioned,  are  available 
as  surplus  material  for  $2.00  or  less  each. 

A  crystal-controlled  frequency  marker  such  as 
is  described  here  can  be  built  for  from  $15  to  $20 
if  all  parts,  including  the  crystal,  must  be  pur- 
chased new.  Of  course,  if  the  receiver  is  provided 
with  suitable  power-supply  terminals,  filament 
and  plate  power  could  be  taken  from  the  receiver, 
in  which  case  the  cost  can  be  still  further  reduced 
by  omitting  the  filament  transformer  and  recti- 
fier-filter system. 

The  high  precision  and  small  size  of  this  self- 
contained  unit  make  it  an  especially  useful  piece 
of  equipment  for  the  radio  amateur. 


Overtone  Crystals

more  capacitor  than  the  circuit  of  Fig.  2A,  and 
it  will  usually  work  well  with  crystals  of  either 
the  overtone  or  fundamental  variety  inter- 
changeably. We've  used  it  repeatedly  for  3rd- 
overtone  work  with  crj^stals  in  the  6-  to  9-Mc. 
range,  and  have  had  no  trouble  getting  5th-over- 
tone  oscillation  with  3.5-Mc.  crystals. 

In  some  applications  it  may  be  desirable  to 
have  the  crystal  oscillator  as  high  in  frequency 
as  possible.  This  is  particularly  true  of  crystal- 
controlled  converters,  where  energy  at  fre- 
quencies other  than  the  desired  one  may  cause 
birdies  and  spurious  responses.  For  converter  use 
the  circuit  of  Fig.  2C  may  have  merit.  This  was 
suggested  to  the  writer  by  Clare  Reynolds, 
W9MBI,  of  the  James  Knights  Crystal  Co., 
Sandwich,  111.  He  uses  it  in  v.h.f.  converters,  and 
has  also  had  direct  control  of  an  oscillator  at  144 
Mc.  m  a  low-powered  2-meter  transmitter.  He

reports  that  frequencies  as  high  as  216  Mc.  have 
been  obtained  with  direct  control,  involving 
overtones  as  high  as  the  11th,  with  this  circuit. 

The  critical  element  here  is  the  value  of  the 
two  resistors  on  either  side  of  the  crystal.  In- 
creasing them  causes  more  feed-back,  encourag- 
ing the  tendency  to  self-oscillation  and  "squeg- 
ging."  Dropping  their  value  much  below  that 
specified  cuts  out  oscillation  altogether.  We 
checked  many  types  of  fundamental  crj'stals  in 
this  circuit  in  the  Headquarters  lab,  with  the 
usual  result:  In  going  through  dozens  of  crystals 
in  the  range  between  6  and  9  Mc,  we  found  only 
two  that  could  be  made  to  oscillate  on  overtones 
higher  than  the  5th,  and  very  few  would  even  go 
this  high,  though  all  worked  well  on  the  3rd. 
However,  when  we  checked  about  20  overtone 
crystals,  higher  overtones  were  found  with  ease. 
With  any  3rd-mode  crystal,  the  5th  and  7th 
modes  were  found  in  every  case,  and  in  most  in- 
stances the  9th  was  usable.  Third-overtone  crj-s- 
tals  around  12  to  15  Mc.  (fundamental  4  to  5 
Mc.)  could  be  operated  on  their  9th,  11th  and 
even  higher  overtones  in  some  instances.  Several 
v.h.f.  crystals  from  the  International  Crystal 
Co.,  Oklahoma  City,  for  frequencies  between  40 
and  50  Mc.  were  made  to  oscillate  as  high  as  150 
Mc.  These  were  3rd-overtone  crystals  in  CRT- 
type  holders. 

Precautions  with  Overtone  Crystals 

Too  many  hams  regard  the  frequency  marked 
on  a  crystal  holder  as  a  fixed  value,  to  be  relied 
upon  regardless  of  how  the  crystal  is  used.  It 
should  be  borne  in  mind  that  even  when  the  crys- 
tal is  used  at  the  fundamental  frequency,  the 
value  marked  on  the  holder  applies  only  to  the 
conditions  under  which  the  crystal  was  checked 
by  the  manufacturer.  Changing  the  load  capaci- 
tance into  which  the  crystal  works,  using  it  in 
different  circuits,  or  running  it  hotter  than  the 
manufacturer  specifies,  can  make  the  frequency 
something  quite  different.  Exact  calibration  may 
not  be  important  unless  you  are  planning  to 
work  close  to  band  edges,  but  staying  with  the 
recommended  operating  conditions  as  to  crj'stal 
current  is  important,  if  you  want  stability. 

Most  overtone  crystals,  being  of  the  plated 
variety,  are  incapable  of  dissipating  much  heat. 
This  means  that  the  crystal  oscillator  must  be 
operated  at  low  power  level,  and  with  no  more 
feed-back  than  is  necessary  to  maintain  good 
starting  characteristics  under  load.  The  cr3'stal 
oscillator  should  never  be  thought  of  as  a  power- 
generating  device,  and  this  is  particularly  true  of 
overtone  oscillators.  The  oscillator  should  gener- 
ate a  stable  signal;  stepping  up  the  power  should 
be  left  to  succeeding  stages. 

When  fundamental  crystals  are  used  on  over- 
tones, the  frequency  of  oscillation  may  not  be  an 
exact  multiple  of  the  marked  frequency.  And  the 
frequency  will  be  different  for  series  or  parallel 
resonance.  Moral:  When  working  anywhere  near 
l)and  edges,  have  some  accurate  means  of  check- 
ing frequency;  a  crystal  marking  is  no  guarantee 
that  you  will  be  inside  the  band.

Here's  a  little  quiz  based  on  articles  ap- 
pearing in  QiS'7'  for  January.  How  much 
do  you  remember  from  the  issue  of  two 
months  ago? 

1.  What  antenna  popular  during  the  IO- 
meter opening  in  the  '40s  has  been  revived 
as  a  20-meter  beam? 

2.  An  average  car  antenna  is  just  the 
right  length  for  which  amateur  band? 

3.  Use  of  the  grounded  grid  amplifier 
eliminates  what  troublesome  problem? 

4.  The  League  recently  filed  comment 
on  FCC  Docket  11157.  What  does  this 
docket  propose? 

5.  What  contests  were  held  by  ARRL 
during  January? 

VV  hether  you  got  them  all  right  or  not 
isn't  too  important.  What  is  important  is 
the  fact  that  whenever  you  need  in- 
formation about  ham  radio — antennas, 
mobile  gear,  transmitters,  regulatory 
developments,  operating  events  or  other 
amateur  matters — the  right  answer  is  in 
QST.

The  common  test  for  self-oscillation,  pulling 
out  the  crystal  to  see  if  oscillation  stops,  is  not 
applicable  to  most  overtone  circuits.  The  capaci- 
tance of  the  crj^stal  and  its  holder  is  a  part  of  the 
feed-back  circuit.  If  there  is  self-oscillation  pres- 
ent, it  will  almost  invariably  stop  when  the  crys- 
tal is  removed. 

In  trying  for  high-order  overtones,  it  may  be 
necessary  to  bring  feed-back  up  to  the  point 
where  self-oscillation  develops  when  the  tuned 
circuits  are  resonated  at  frequencies  away  from 
the  desired  overtone.  If  a  receiver  covering  the 
range  is  available,  the  self-oscillation  frequency 
may  be  checked  as  the  circuits  are  varied.  When 
the  desired  overtone  is  approached  there  will 
usually  be  a  sudden  jump  in  frequency  to  that 
overtone,  whereupon  the  signal  (with  b.f.o.  on) 
will  become  stable  and  musical  in  tone,  instead 
of  raspy  and"  subject  to  frequency  shift  during 
even  slight  mechanical  vibration.  Adjustment 
of  such  circuits  is  critical,  and  it  usually  will  not 
be  right  for  more  than  one  crj'stal. 

The  tuning  of  circuits  associated  with  overtone 
crystals  affects  the  frequence'  of  oscillation  appre- 
ciably. There  may  be  shifts  of  50  kc.  or  more  in 
the  1-14-Mc.  band  when  tuning  overtone  circuits. 
Thus  it  can  be  seen  that  they  are  unsuited  to 
shaving  the  band  edges. 

To  Use  or  Not  To  Use? 

From  what  we  have  said  here  it  can  be  seen 
that  the  ability  to  work  with  direct  crystal  con- 
trol in  the  v.h.f.  range  is  not  an  unalloyed  bless- 
ing. There  are  applications,  however,  w^here 
overtone  techniques  have  much  to  recommend 
them.  They  are  almost  a  must  in  crystal-con- 
trolled converters,  for  instance.  Here  you  want 
freedom  from  birdies  in  the  form  of  crystal  har- 
monics, and  you  also  want  the  energy  you  inject 
into  the  mLxer  to  be  as  free  as  possible  from  fre- 
quencies other  than  the  desired  one.  If  you  can 
get  direct  control  at  the  injection  frequency  in 
your  crystal-controlled  converter,  by  all  means 
do  it.  The  power  output  required  is,  of  course, 
very  low,  so  you  can  achieve  high  stability  in  your 
converter  readily.  And  you're  not  going  to 
change  injection  frequencies,  so  critical  adjust- 
ment is  not  an  important  deterrent.  You're  go- 
ing to  have  to  do  the  job  only  once. 

Third-overtone  operation  of  cheap  and  plenti- 
ful surplus  crystals  in  the  8-Mc.  range  is  often  a 
convenient  and  economical  way  of  controlling 
the  frequency  of  v.h.f.  transmitters.  If  circuit 
simplicity  and  low  power  drain  are  important 
considerations,  along  with  low  cost,  overtone  cir- 
cuits are  certainly  attractive. 

But  suppose  you're  going  to  build  an  exciter 
that  you  hope  to  use  on  several  bands.  You  want 
the  oscillator  to  work  with  3.5-,  6-,  7-,  8-,  12-  or 
14-Mc.  cr\'stals,  so  as  to  make  use  of  a  stock  you 
have  on  hand.  Quite  likely,  j-ou'll  want  to  have  a 
VFO  to  work  into  the  crystal-oscillator  stage,  too. 
Simplicity  and  low  first  cost  are  minor  considera- 
tions in  such  a  design,  compared  to  the  con- 
venience of  being  able  to  use  any  type  of  crystal.

for  such  apphcations,  obviously.  You'll  build  this 
rig  with  all  the  customary  TVI-prevention  meas- 
ures, anyway,  so  the  possibility  that  unwanted 
multiples  of  the  oscillator  frequencies  may  ap- 
pear in  the  output  is  of  little  importance.  A  care- 
ful consideration  of  all  the  design  factors  will 
enable  you  to  make  a  wise  choice  as  to  whether 
overtone-oscillator  techniques  are  attractive  for 
the  job  you  have  in  view.

harmonic  attenuation.  Note  the  similarity  of 
Fig.  3B  to  a  low-pass  filter  section.  It  should  be 
possible  to  match  either  52-  or  72-ohm  coax  with- 
out difficulty. 

The  nominal  rating  of  the  components  used  is 
500  watts.  The  major  operating  precaution  is  not 
to  operate  the  circuit  switch  »Si  with  the  power 
api)lied.  These  switches  can  carry  quite  a  bit 
more  current  than  they  can  break.  The  same 
precaution  applies  with  somewhat  lesser  weight 
to  S2  and  Li. 

The  L-C  matching  section  may  be  used  by 
itself  for  matching  grounded  antennas  by  bring- 
ing the  antenna  line  in  and  tapping  into  the 
coupler  at  the  point  marked  "X"  in  Fig.  1. 
No  coil  should  be  plugged  in  the  jackbar,  and 
switch  (Si  must  be  in  position  2  or  S.  The  only 
precaution  is  to  observe  the  voltage  ratings  of 
the  capacitors  in  the  matching  section. 

If  the  same  type  of  ceramic  stand-offs  are  used 
as  those  in  the  photographs,  be  extremely  careful 
when  mounting  them  to  the  metal  panel,  as  they 
break  very  easily.  Fiber  washers  under  the 
nuts  and  between  the  ceramic  and  the  panel 
should  help  considerably.

Air-System 
Sockets 


tinidC  air-system  sockets  are  custom  designed  to  provide 
adequate  cooling  with  the  most  economical  blower  requirements 
for  several  Eimac  radial-beam  power  tetrodes. 

4-400A  4000  air-system  socket  is  employed  with  Eimac  tube 
type  4-400A.  Air  enters  through  the  bottom  of  the  socket  and  is 
guided  by  a  pyrex  glass  chimney,  assuring  efficient  cooling  of 
the  various  seals.  If  desired,  this  socket  may  also  be  used  with 
Eimac  4-125A  and  4-250A. 

4-1000A  4000  air-system  socket  is  designed  for  use  with  Eimac 
tube  type  4-lOOOA.  Air  entering  the  bottom  of  the  socket  is 
guided  by  a  pyrex  glass  chimney  toward  the  plate  seal,  assuring 
correct  cooling  even  during  maximum  rating  operation  of  the 
tube. 

4X150A  4000  air-system  socket  provides  adequate  air  cooling 
and  high  frequency  circuit  arrangement  for  Eimac  4X150A  and 
4X150D.  Air  enters  the  socket  through  the  bottom  and  is  guided 
by  a  ceramic  chimney. 

4X150A/4010  socket  is  identical  to  the  4X150A;4000  except  that 
this  socket  IS  complete  with  grounded  cathode  connecting  tabs. 

Eimac  air-system  sockets  and  chimneys  are  also  available  as 
separate  units.

worked;  however,  instability,  tracking  difficul- 
ties, and  oscillator  pulling  were  quite  bad  above 
7  Mc.  This  condition  was  attributed  to  insuffi- 
cient frequency  separation  and  the  consequent 
reactance  of  the  local  oscillator  circuit  coupled 
into  the  cathode  of  the  mi.xer,  producing  sufficient 
phase  shift  to  cause  oscillation  in  the  mixer  and 
pulling  of  the  local  oscillator  frequency.  Again, 
the  6C4  cathode  follower  provided  a  practical 
solution,  by  giving  necessary  isolation,  resulting 
in  a  cool,  smooth-running  low-noise  mixer.  No 
further  difficulty  with  tracking  was  encountered. 

Circuitry 

Fig.  1  shows  our  low-noise  front-end  circuit. 
No  a.v.c.  should  be  used  on  the  first  r.f.  stage. 
It  should  be  emphasized  that  in  order  to  utihze 
the  grounded-grid  triode  mixer  it  is  imperative 
to  use  a  separate  h.f.  oscillator.  Although  a  con- 
verter circuit  may  appear  complicated,  a  little 
study  will  reveal  that  it  consists  of  simple  triode- 
oscillator,  signal-input  and  i.f.  output  circuits. 
Fig.  2  illustrates  modification  of  two  common 
types  of  single-tube  converters  to  separate  oscil- 
lator mixers  for  use  in  this  low-noise  front  end. 
There  is  nothing  tricky  about  making  this  modi- 
fication. One  precaution:  connect  all  grounds  to 
the  cathode  return  of  the  stage  being  wired.  The 
use  of  tube  shields  for  all  the  6C4s  is  recom- 
mended, especially  if  they  are  mounted  below 
deck,  as  was  the  case  in  our  receiver.  Although 
major  realignment  will  not  be  necessary,  a  touch- 
up  of  the  trimmer  capacitors  at  the  high  end  of 
each  hand  may  be  required.  Readjust  the  oscilla- 
tor trimmers  first  to  bring  the  receiver  back  into 
calibration;  then  the  r.f.  and  mixer  trimmers  for 
maximum  gain. 

Conclusion 

Here  is  a  circuit  that  for  the  first  time  makes 
practical  the  use  of  low-noise  techniques  in 
general-coverage  receivers.  It  is  easily  applied  to 
any  receiver  without  introducing  additional 
knobs  or  alterations  to  existing  tuned  circuits 
and,  furthermore,  works  at  the  first  try.  The  few 
extra  wires  and  components  are  well  worth  the 
time  and  expense.  Comparative  listening  tests 
were  made  on  14  Mc,  between  a  receiver  in- 
corporating this  circuit  and  three  late-model 
stock  commercial  receivers  in  the  $400.00  class. 
Listening  fatigue  attributable  to  internal  noise 
was  considerably  less,  and  twice  as  many  DX 
stations  were  heard.

again,  the  capacitor  is  made  up  of  concentric 
aluminum  or  dural  tubing  separated  with  poly- 
styrene, and  the  coil  is  concentric.  In  each 
capacitor,  the  polystyrene  insert  (Fig.  4)  should 
provide  a  tight  fit  to  both  sections  of  tubing, 
and  the  insert  should  be  driven  into  the  outer 
conductor  to  the  shoulder.  The  inner  conductor 
should  be  driven  into  the  insert  for  a  distance 
of  2^  inches  (thus  protruding  2  inches  inside 
the  outer  conductor).  This  gives  a  capacitance 
of  approximately  25  ix^l.  The  trap  inductors  are 
wound  with  No.  8  wire.  The  10-meter  inductors 
have  5  turns  2]/2  inches  in  diameter,  with  the 
turns  spaced  approximately  ^^  inch.  The  21-Mc. 
inductors  are  similar,  but  have  7  turns.  As  with 
the  wire-antenna  traps,  the  inductors  should  be 
adjusted  for  resonance  near  the  center  of  each 
band  before  they  are  installed.  The  ends  of  the 
inductors  are  wound  around  the  element  sections 
and  fastened  with  clamps.  The  array  is  fed  with  a 
T  match  to  75-ohm  Twin  Lead. 

Fig.  3  shows  the  element  dimensions  used  by 
the  author.  Antennas  of  this  type,  in  both  wire 
and  beam  forms,  have  been  installed  by  many 
amateurs,  using  traps  constructed  by  the  author. 
Without  exception,  all  have  been  enthusiastic 
about  the  performance. 


"Hidden  Gem" 

{Continued  from  page  24) 

A  Vari-Loopstick  is  used  for  L\,  as  suggested  by 
W8EIY.  It  is  a  commercial  slug-tuned  induct- 
ance which  is  widely  used  as  a  broadcast-receiver 
antenna.  It  sells  for  less  than  a  dollar,  and  re- 
quires only  a  small  hole  for  mounting.  It  com- 
prises a  very  compact,  adjustable  tuned  circuit 
consisting  of  its  self-inductance  and  the  dis- 
tributed and  stray  capacitance  of  the  circuit.  It 
peaks  very  nicely  on  75  meters  using  a  transmitter 
or  grid-dip  meter  as  a  signal  source.  Once  the 
Vari-Loopstick  is  peaked  at  75  meters,  no  further 
adjustment  is  ever  necessary,  since  it  is  broad 
enough  to  cover  the  entire  75-meter  band,  and 
the  increased  radiation  efficiencies  on  the  higher- 
frequency  bands  more  than  compensate  for  the 
lack  of  a  tuned  circuit. 

When  it  comes  to  the  pick-up  antenna,  you 
can  really  let  your  imagination  go  to  work.  Only 
a  short  vertical  probe  from  4  to  8  inches  in  length 
is  necessary  if  mounted  on  the  rear  gravel  skirt 
or  on  the  rear-window  deck.  An  unused  broad- 
cast-receiver whip  is  efficient  and  inconspicuous. 
The  antenna  used  here  is  a  right  front-fender 
guide  which  is  insulated  from  the  car  body.  This 
serves  double  duty  liecause  it  works  well  as  a  pick- 
up antenna  and  helps  the  XYL  in  parking.  Any 
insulated  wire  serves  as  a  lead-in  to  the  meter.

Exclusive  at  Radio  Shack!  Sorry  we  can't  tell  you  the  famous  make  of  this 
capacitor,  rated  at  50  mf  at  3  KV  (dc),  but  it's  brand  new  —  NOT  gov't  or 
otner  surplus  —  and  fully  guaranteed.  Provides  excellent  dynamic  regulation 
and  optimuni  power  output  when  filtering  power  supply  for  voice  frequency, 
especially  in  low  frequency  syllabic  loading,  in  suppressed  carrier  single  side-band 
transmitter  operation.  Mild  steel  construction,  finished  gray.  Size:  MV^"  wide, 
5/4  deep,  14>/2  high.  Insulator  bushing  and  stud  terminal  4"  high.  Mounting 
center  IS'/g '  for  i/»"  bolts.  Allow  for  75  lb.  ship.  wt.  NOTE:  the  quantity  is 
very  limited  —  first  come,  first  served. 

REFERENCE:  See  GE  "Ham  News"  of  Jan.-Feb.  and  March-April  1954  for 
data  on  better  dynamic  regulation  and  power  supply  design.  The  value  of  this 
capacitor  will  then  be  even  more  fully  appreciated.

Using  the  F.S.  Indicator 

Once  your  field-strength  indicator  is  installed, 
it  may  reveal  some  surprising  facts  about  your 
transmitting  system.  For  instance,  you  may  find 
that  maximum  output  does  not  occur  at  the 
plate-current  dip  but  somewhere  off  to  one  side. 
You  may  find  that  output  does  not  continue  to 
increase  with  increased  coupling,  even  if  the 
plate  current  does  go  up  and  you  still  are  able 
to  get  a  plate  dip.  A  point  is  sometimes  reached 
where  increased  coupling  merely  heats  your  final 
amplifier  and  the  transmission  line,  and  actually 
decreases  power  output.  If  your  grid  drive  is 
adjustable,  you  may  find  that  there  is  an  opti- 
mum setting  for  it,  too.  Too  much  drive  may 
drop  the  output  just  as  too  little  will.  You  will 
be  able  to  find  the  exact  frequency  at  which 
your  antenna  sj^stem  radiates  best  and  you  will 
be  able  to  prune  your  antenna  to  any  desired 
frequency.  The  system  followed  here  to  QSY  the 
antenna  on  75  meters  is  to  use  capacity  sprigs 
clipped  on  the  antenna  above  the  loading  coil. 
The  sprigs  are  short  lengths  of  stiff  copper  wire 
and  attached  to  small  battery  clips.  If  the 
antenna  itself  is  tuned  to  the  high  end  of  the 
band,  four  sprigs  of  different  lengths  will  enable 
you  to  cover  most  of  the  band  with  reasonable 
efficiency  and  will  spot  five  frequencies  for  maxi- 
mum output.  If  you  are  using  one  of  the  new 
continuously-variable  loading  coils,  your  field- 
strength  indicator  will  help  you  to  determine  the 
correct  tuning  in  a  hurry. 

And  not  the  least  value  of  this  gadget  is  its 
ability  to  let  you  know  that  you're  actually 
radiating.  You  won't  have  to  tear  the  transmitter 
apart  or  run  a  special  check  when  you  fail  to 
raise  a  station,  if  your  meter  is  indicating  normal 
output.  You  can  just  conclude  that  the  other 
guy  is  deaf  or  has  left  the  antenna  off  his  receiver. 

The  sensitivity  control  should  be  turned  all 
the  way  down  when  the  indicator  is  not  in  use  to 
protect  the  movement  from  overload  if  you 
should  get  too  close  to  a  strong  commercial  sta- 
tion. This  also  damps  the  meter  against  mechan- 
ical vibration. 

The  indicator  can  be  constructed  in  a  couple 
of  hours,  and  attached  to  your  car  in  even  less 
time.  About  the  only  cost  of  any  consequence  is 
the  meter  movement,  but  almost  everyone  should 
have  some  meter  available  which  can  be  used. 
Remember,  the  larger  the  pick-up  antenna  and 
the  closer  it  is  placed  to  the  radiating  antenna,  the 
less  sensitive  the  meter  movement  required.  With 
fifty  watts  input,  a  150-jua.  movement  is  more 
than  ample  when  using  the  fender-guide  pick-up. 

No  matter  whether  you're  running  a  mobile 
kilowatt  or  only  a  half  pint,  whether  you  have  a 
super  high-Q  antenna  or  just  a  piece  of  wire,  a 
mobile  field-strength  indicator  will  at  least  result 
in  the  self-satisfaction  of  knowing  when  you  are 
getting  the  maximum  available  output  from  your 
system.  It  will  also  let  you  know  if  changes  in 
your  system  are  of  any  benefit,  and  should  result 
in  more  and  better  QSOs.  You  probably  will 
discover  other  uses  and  applications  yourself.

his  call),  the  hidden  transmitter,  inviting  all 
mobiles  on  29  megacycles  to  jjarticipate  in 
tonight's  hidden-transmitter  hunt.  We  are  in 
the  south  sector  (or  north  sector  if  he  is  in  the 
north  half  of  the  city).  We  shall  start  the  hunt 
with  a  roll  call.  All  participating  stations  please 
identify  themselves.  This  is  W7QPR  mobile,

participating  stations  take  a  bearing,  determine 
the  axis,  and  possibly  the  direction  of  the  hidden 
transmitter,  and  start  after  him,  announcing 
their  calls  for  the  roll  call.  After  the  initial  trans- 
mission, the  bunny  may  remain  silent  until  he  is 
called.  When  he  is  called,  he  transmits  for  fifteen 
or  twenty  seconds,  allowing  the  pack  to  get  a 
"fix"  on  him.  The  idea  is  to  ask  for  as  few  trans- 
missions as  are  necessary,  because  each  time  a 
participating  station  asks  for  a  transmission,  the 
whole  group  takes  a  bearing. 

On  a  typical  hunt,  the  first  bearing  was  taken 
at  point  A,  Fig.  3,  and  this  indicated  a  northeast-

to-southwest  axis  (A  to  B).  The  author  drove 
about  a  mile  westward  to  point  C  and  called  for 
a  transmission.  The  bearing  then  appeared  in  a 
more  north-to-south  direction,  indicating  that 
the  bunny  was  definitely  to  the  south  and  a  little 
west.  Driving  south  (the  streets  run  due  north 
and  south),  bearings  were  taken  at  D,  E,  and  F, 
as  other  mobiles  called  for  transmissions.  By  this 
time,  the  author's  XYL,  who  was  the  copilot, 
and  the  two  junior  ops  in  the  back  seat  were 
calling  for  a  turn  to  the  west.  At  G,  a  transmission 
was  asked  for  and  it  indicated  that  the  author 
was  south  of  the  bunnv's  east-to-west  axis.  So, 
turning  west,  bearings  were  taken  at  points 
H  and  A'.  Position  A'  showed  that  the  author 
was  west  of  the  north-to-south  axis  of  the  hidden 
transmitter.  The  author  then  drove  northward

Here  is  a  must  for  all  mobile  hams!  .  .  .  The 
new  heavy-duty  Master-Flex-'R.  designed  to 
relieve  the  stress  and  strain  and  prevent  dam- 
age that  could  be  transmitted  to  the  loading 
coil.  The  Master-Flcx-'R  protects  the  whip  and 
prevents  the  loading  coil  from  injury  and  de- 
tuning while  driving  at  high  speed,  or  from 
overhanging  limbs  and  driving  into  garage. 
Permits  whip  to  be  fastened  down  to  car  on 
bumper  mount  installations  of  late  model  cars. 
Made  of  sturdy  spring  steel,  yet  flexible 
enough  to  absorb  all  the 
shock.  Heavy  cadmium  fini

indicated  the  bunny  was  due  east.  Turning  east, 
the  bunny  was  located.  He  had  been  hiding  be- 
tween two  buildings  on  a  school  ground. 

The  author  calls  this  the  "spiral"  technique. 
It  cuts  down  the  possibility  of  passing  the  bunny 
without  realizing  it,  a  condition  that  might  easily 
occur  if  the  hunter  tried  to  drive  directly  to  the 
bunny. 

Well,  that's  how  it  is  done  in  Seattle,  to  say 
nothing  of  the  coffee  and  rag-chew  at  the  favorite 
beanery  after  the  hunt.  So,  bundle  the  XYL  and 
the  junior  ops  in  the  family  chariot  and  really 
have  some  fun.

(Continued  from  page  35) 

The  heaters  are  originally  in  series-parallel  for 
24-volt  operation.  They  are  easily  rewired  in 
parallel  if  the  mounting  screws  holding  the 
capacitors  over  each  tube  socket  are  removed  and 
the  capacitors  carefully  moved  out  of  the  way 
while  making  the  necessarj'^  changes. 

An  additional  stage  of  audio  is  necessary  to 
obtain  good  speaker  volume.  A  small  sub-chassis 
was  made  from  light-weight  galvanized  metal 
and  soldered  to  two  opposite  capacitors,  as 
shown  in  the  photograph.  A  seven-pin  miniature 
socket  was  mounted  on  this  chassis  to  take  the 
6C4  audio  tube. 

The  second  detector  was  modified  as  shown  in 
Fig.  2.  The  wiring  for  the  a.v.c,  a.n.l.,  and  6C4 
audio  stage  is  also  shown  here.  The  long  leads 
going  to  the  audio  gain  control  should  be  shielded. 
Manj'  of  the  components  in  Fig.  2  are  already  in 
the  original  set.  Douglas  R.  Jordan's  article, 
"New  Life  for  the  Q5-er,"  QST,  February,  1951, 
will  be  helpful  to  the  builder. 

After  these  modifications,  the  BC-453-A  is  a 
high-performance  mobile  receiver.  I  believe  it  to 
be  the  only  unit,  easily  obtainable,  qualified  for 
s.s.b.  mobile  reception.

S.W.R.  Bridge 

(Continued  from  page  31) 

Ci  is  also  tuned  for  minimum  or  a  null.  It  may 
he  necessary  to  readjust  both  Ci  and  C2  to  get 
the  best  possible  null.  The  taps  on  L2  may  have 
to  be  moved  toward  the  center  of  the  coil  if  a 
good  null  isn't  obtained  with  the  tap  near  the 
outside.  However,  though  there  may  be  more 
than  one  set  of  conditions  that  will  give  a  good 
null,  the  best  condition  is  with  the  taps  as  close 
to  the  ends  as  possible.  When  the  best  reading  is 
obtained,  the  bridge  can  be  removed  from  the 
coax  line  and  the  line  connected  directly  to  the 
transmitter.  The  transmitter  can  then  be  loaded 
to  the  proper  operating  input. 

There  are  two  points  to  be  remembered.  No 
Natter  what  changes  are  made  at  the  transmitter, 
they  will  have  no  effect  on  the  match  so  long  as 
the  frequency  is  left  the  same  as  when  matched. 
Point  number  two  is  that  the  controls,  Ci,  C2, 
and  the  taps,  should  not  be  changed  after  the 
system  is  matched.  Again,  this  holds  true  for  a 
given  frequency.  Any  loading  adjustments  should 
be  made  at  the  transmitter,  not  the  coupler. 

With  the  system  matched,  it  will  probably  be 
noticed  that  it  is  possible  to  vary  the  operating 
frequency,  without  retuning  the  antenna  coupler, 
over  a  wider  range  than  was  possible  before.  The 
actual  range  will  depend  upon  the  antenna  sys- 
tem. The  settings  of  Ci,  C2,  and  the  taps  can  be 
noted  for  each  particular  point  in  the  band  and 
it  then  becomes  a  simple  matter  to  change  the 
controls  to  the  correct  setting  whenever  the  op- 
erating frequency  is  changed. 

Coax-Fed  Antennas 

Another  place  the  s.w.r.  bridge  does  yeoman 
duty  is  in  the  case  of  a  coax-fed  beam,  such  as  is 
used  on  the  20-,  15-,  and  10-meter  bands.  As- 
suming that  we  are  going  to  match  a  15-meter 
beam  fed  with  72-ohm  coax,  the  procedure  is 
simple.  The  bridge  is  connected  to  the  transmitter 
with  a  piece  of  72-ohm  coax  and  full-scale  read- 
ing is  obtained  with  the  output  side  of  the  bridge 
disconnected.  After  full-scale  reading  is  reached, 
the  line  to  the  antenna  is  connected  to  the 
bridge.  The  matching  network  at  the  antenna  is 
then  adjusted  for  the  lowest  possible  reading  on 
the  milliammeter.  When  a  reading  of  zero  or 
close  to  it  is  obtained,  one  can  be  fairly  sure  that 
the  antenna  is  acting  as  a  72-ohm  load  for  the 
72-ohm  coax  and  the  s.w.r.  is  very  low.  The 
bridge  is  removed  from  the  line  and  the  trans- 
mitter can  be  loaded  up.  You  can  then  be  pretty 
sure  the  r.f.  is  going  to  the  antenna  and  not 
being  used  up  as  heat  in  the  feed  line. 

If  one  is  interested  in  making  actual  standing- 
wave-ratio  measurements,  the  Measurements 
chapter  of  the  Handbook  describes  an  excellent 
bridge  that  can  be  used  for  this  purpose.  How- 
ever, for  making  sure  your  antenna  system  is 
working  properly,  the  unit  described  here  is 
worth  its  weight  in  the  24-carat  stuff.

not  care  to  tie  up  a  transformer  and  the  necessary 
filter  components  in  a  supply  that  will  be  em-

control,  Ri,  adjusted  for  an  output  of  225  volts, 
showed  no  voltage  drop  at  loads  as  high  as  77  ma. 
When  adjusted  for  an  output  of  250  volts,  the 
regulation  was  constant  up  to  loads  of  60  ma.  and 
a  drop  of  no  more  than  5  volts  was  measured  with 
the  load  increased  to  77  ma.  At  275  volts,  the 
output  remained  steady  with  leads  up  to  54  ma. 
and  fell  to  approximately  240  volts  with  the  drain 
raised  to  77  ma. 

Variations  in  the  design  to  meet  special  condi- 
tions are  possible.  In  addition  to  the  ripple  filter 
shown,  the  connection  of  a  0.002-yu/if .  mica  capaci- 
tor across  the  VR-75  will  reduce  the  noise  ampli- 
fication, in  which  case  the  20-/xf.  capacitor  can  be 
eliminated.  Of  course,  the  filament  voltage  applied 
to  the  regulator  tubes  cannot  be  used  for  equip- 
ment powered  by  the  regulator  unit.  —  E.  P.

signal,  and  seems  to  be  conscious  of  the  fact  that  they  have 
to  sell  the  thing  in  the  proper  light.  A  fellow  with  a  bad  signal 
finds  out  about  it  quickly.  The  vast  majority  of  s.s.b.  oper- 
ators are  convinced  that  with  the  proper  operation  of  existing 
receiving  equipment,  not  to  mention  the  excellent  supple- 
mentary units  which  improve  the  existing  equipment,  there 
is  very  little  justification  for  the  criticism  that  s.s.b.  "hogs" 
the  bands.  As  a  group,  and  through  experience,  they  feel 
that  the  opposite  is  true  —  and  a  close  examination  of  the 
number  of  individual  QSOs  in,  let's  say,  any  range  of  10  kc. 
in  the  top  of  the  7o-meter  band,  should  prove  the  point. 
Any  reasonably  good  communications  receiver,  properly 
operated,  can  generally  receive  an  a.m.  signal  much  closer 
to  a  s.s.b.  station  than  it  could  adjacent  to  another  a.m 
signal.  Only  experience  can  prove  this,  not  opinions! 

My  most  serious  concern,  however,  is  the  nature  of  some 
of  the  severe  criticism  and  remarks  being  made  about  the 
so-called  deliberate  interference,  and  also  the  attitudes  of 
some  of  the  a.m.  operators  that  the  s.s.b.  boys  are  supposed 
to  restrict  their  operation  to  a  portion  of  the  band  and  that 
the  rest  of  the  band  is  a.m.  territory  only.  Admittedly,  there 
are  some  rotten  apples  in  the  s.s.b.  barrel,  and  some  of  the 
s.s.b.  boys  are  not  selling  a  thing  but  trouble,  but  as  a  whole, 
the  group  does  not  deserve  the  criticism  tiiat  they  are  re- 
ceiving by  a  minority  group.  It  is  my  personal  opinion  that 
neither  group  owns  any  portion  of  the  band,  nor  any  par- 
ticular frequencies  therein.  I  believe  that  that  is  also  re- 
corded as  a  matter  of  law!  ' 

It  is  also  my  opinion  that  these  remarks  have  progressed, 
or  rather  digressed,  to  the  point  where  they  are  rapidly  be- 
coming a  black  eye  to  the  ham  fraternity  in  general.  I  be- 
lieve it  is  meant  that  the  ham  bands  can  be  used  for  free  and 
intelligent  discussion  of  these  issues,  but  that  they  are  not 
meant  to  be  used  by  a  minority  group  for  the  purpose  of 
insulting  the  person,  integrity,  and  character  of  anyone 
who  does  not  believe  as  they,  the  minority,  do.  Furthermore, 
this  group's  only  sensible  argument  to  the  issue  is  that  they 
are  not  in  the  minority.  They  are,  I  am  sure,  in  the  majority 
in  number,  but  most  definitely  in  the  minority  in  attitude. 
This  group  is,  I  believe,  the  product  of  the  influence  of  a 
certain  few  individuals  who  are  using  the  too-popular  views. 
They  contend  that  the  FCC  is  "investigating  the  matter, 
so  you  s.s.b.  boys  better  get  the  heck  out  of  here."  Per- 
sonally, I  would  welcome  an  FCC  investigation  of  the  issue, 
and  seeing  in  print  what  the  results  of  such  an  investigation 
would  disclose.

Editor,  QST: 

As  an  amateur  who  built  and  operated  "wireless"  equip- 
ment long  before  the  spark-tube  hassle  of  the  Twenties,  I 
was  amused  at  the  rantings  of  W4WQT  in  his  letter  pub- 
lished in  the  December  issue  of  QST. 

While  some  of  us  have  probably  not  done  much  to  unite 
the  amateurs,  we  are  certainly  not  trying  to  divide  them 
over  the  small  issue  of  s.s.b.  versus  d.s.b.  We  feel  that  the 
caliber  of  remarks  used  in  W4WQT's  letter  is  entirely  un- 
called for  and  inexcusable  and  that  Q^T  lias  struck  some  kind 
of  a  new  low  in  publishing  it.

cerning single  sideband.  I  quite  agree  with  him.  This  is  the 
new  era  and  sideband  is  the  coming  thing.  But  at  this  time, 
I  wish  to  say  live  and  let  live.  Surely  there  is  adequate  space 
for  all  of  us.  no  matter  what  our  mode  of  operation.  The 
amateur  clan  are  supposed  to  be  gentlemen;  let  us  live  up  to 
this  and  try  to  get  along  in  peace  and  harmony.

SECURITY  RULES 

QST  has  earlier  reported  (p.  46,  August  1954)  a 
proposal  by  FCC  to  amend  our  rules  to  exclude 
from  eligibility  for  an  amateur  license  any  person 
who  is  a  member  of  the  Communist  party,  or 
Communist-front  organization,  or  any  group  ad- 
vocating the  overthrow  of  the  U.  S.  Government 
b}'  force.  Additionally  it  was  proposed  that  only 
persons  of  good  moral  character  would  be  eligible 
for  amateur  licenses;  factors  to  be  considered  in 
this  connection  are  former  membership  in  above- 
mentioned  organizations,  and  conviction  of  a 
felony.  Because  of  the  varied  comments  filed  and 
"the  legal  questions  which  have  been  raised," 
FCC  has  designated  the  matter  for  oral  argument 
to  be  held  in  Washington  on  March  7,  1955. 

NOVICE  EXPANSION  PROPOSED 

In  late  January  FCC  issued  a  Notice  of 
Proposed  Rule  Making  to  expand  the  40-meter 
Novice  segment  to  read  7150-7200  kc.  This  ac- 
tion is  based  on  a  request  of  the  League  formu- 
lated at  the  1954  meeting  of  the  Board  of  Direc- 
tors. Date  for  filing  comment  is  April  15,  1955. 

Readers  may  recall  that  when  in  early  1952  the 
Commission  proposed  7175-7200  kc.  for  Novices, 
the  League  heartily  endorsed  the  idea  but  asked 
that  the  segment  be  a  full  50  kc.  FCC  decided 
not  to  grant  ARRL's  request  at  that  time,  be- 
lieving that  it  would  be  better  to  wait  until  some 
Novice  operation  there  provided  some  experience 
on  which  to  base  judgment  concerning  a  possibly 
larger  band.  As  stated,  in  1954  the  League  re- 
iterated its  request,  which  has  now  taken  the 
form  of  proposed  rule-making.

them  first  with  a  code  oscillator,  repeating  the  text  on  voice 
shortly  after.  This  not  only  spreads  the  latest  news  of  ARRL 
afJairs,  but  also  provides  much-needed  code  practice  for 
quite  a  few  of  the  gang  who  do  not  get  code  experience  in 
any  other  way. 

W2TTU's  summary  in  January  QST  (Fig.  5,  page  13)  and 
other  long-term  records  show  that  auroral  activity  is  not 
common  in  January,  but  two  of  the  best  aurora  sessions  in 
years  came  on  consecutive  nights,  the  17th  and  18th,  of 
January,  1955.  These  did  not  follow  the  usual  pattern  as  to 
time,  either,  both  apparently  getting  under  way  around 
2245  EST,  and  running  for  about  two  hours.  This  is  about 
the  time  of  night  when  auroras  that  have  started  earlier 
taper  off.  Activity  in  these  was  considerable,  and  reports 
of  stations  heard  and  worked  have  been  received  from  as 
far  east  as  WIBCN,  out  on  the  elbow  of  Cape  Cod,  and  as 
far  west  as  W7DYD  and  W7TMU  in  Washington,  as  well  as 
from  scores  of  stations  in  between. 

For  years  the  v.h.f.  operators  who  take  advantage  of  the 
fun  and  DX  that  only  aurora  sessions  offer  have  been  some- 
thing of  an  exclusive  club.  You  hear  the  same  fellows  in 
there  every  time.  You  also  hear  dozens  of  roaring  completely 
unintelligible  carriers  of  'phone  stations,  some  of  them 
undoubtedly  coming  from  fellows  who  would  be  amazed 
if  they  knew  how  far  they  were  getting  out  at  the  time.

Requiring  some  use  and  knowledge  of  the  code,  aurora 
DX  does  not  get  the  play  it  deserves  Perhaps  some  liesitate 
to  jump  in,  fearing  that  their  lack  of  skill  in  the  handling  of 
c.w.  will  show  uj)  glaringly.  But  nobody  need  worry  on  that 
score.  Few  v.h.f.  men  are  c.w.  operators  of  long  experience, 
and  many  are  just  getting  tlieir  first  licks  in.  Even  if  you 
could  send  and  receive  at  40  w.p.m.,  there  would  be  no 
point  in  doing  it,  as  experience  has  shown  that  there  is  little 
to  be  gained  in  going  much  beyond  15  in  auroral  communica- 
tion. If  15  w.p.m.  sounds  like  high  speed  to  you,  don't  let 
that  stop  you;  there  is  no  more  cooperative  group  of  hams 
anywhere  tlian  you'll  find  on  6  or  2  during  an  aurora  session. 
They'll  be  glad  to  work  you  at  any  speed 

So  why  not  fix  up  a  system  for  keying  your  transmitter 
right  now?  Then  you'll  be  ready  to  partake  of  one  of  the 
most  interesting  experiences  ham  radio  has  to  offer,  the  next 
time  the  aurora  lights  the  northern  skies.  Look  through  the 
top  calls  in  Wl,  2,  3,  4,  8,  9  and  0  in  the  2-meter  states- 
worked  box.  .\lmost  without  exception,  they  got  there  via 
the  auroral  route.  There's  no  easier  way  to  move  up  the 
ladder,  and  you'll  get  the  thrill  of  your  ham  career  when  you 
join  the  aurora  club! 


OES  Notes 

Wl  UIZ.  Salem,  Conn.  —  Nightly  skeds  with  WlWIIC/1, 
Wellfleet,  Mass.,  indicate  that  this  120-mile  path  can  be 
covered  regularly  on  144  Mc.  with  readable  voice  signals. 
This  is  at  2130,  and  is  followed  at  2200  by  a  similar  check 
with  WIYQL  Marblehead,  Mass.  The  latter  circuit,  about 
100  miles,  is  also  consistent.  Planning  gear  for  1215  Mc. 

WWHA ,  Collingswood,  N .  J.  —  Round-table  in  Phila- 
delphia area  each  Monday  at  2030  is  big  help  in  keeping  the 
6-meter  gang  together.  As  many  as  12  stations  participate, 
and  more  are  invited.  Heavy  antenna  damage  during  fall 
hurricanes  has  now  been  largely  repaired. 

W 3 KL A,  Baltimore,  Md.  —  Equipment  under  construc- 
tion :  coaxial  tank  circuit  for  4X150A,  amplifier  for  144  Mc, 
will  also  operate  as  doubler  to  220.  W3YQD  now  keeping 
nightly  sked  on  220  with  W4UMF,  Arlington,  Va.,  at  2115. 
WSOTC,  Silver  Spring,  Md.  —  50-Mc.  activity  holding 
up  well  during  winter  months,  with  good  turnouts  for  Sun- 
day-morning and  Monday-night  sessions.  Extraordinary 
50-Mc.  reception  during  Sunday  morning  of  V.H.F.  SS. 
WIFZ,  Farmington,  N.  H.,  answered  CQ,  but  faded  out 
before  complete  exchange  could  be  made.  W30JU,  Wash- 
ington, D.  C,  also  heard  Wis  briefly  during  same  period. 
As  no  exceptional  tropospheric  signals  were  heard,  this  one 
period  of  400-mile  reception  appears  to  have  been  an  extra- 
long  meteor  burst,  or  some  other  form  of  short-duration 
reflection. 

W3UQJ,  York,  Pa.  —  Would  like  to  see  QST  box  listing 
accomplishments  of  220-  and  420-Mc.  stations,  similar  to 
2-meter  box.  After  several  months  of  regular  skeds  on  220 
Mc.  with  W4UMF,  and  contacts  with  Maryland,  there  now 
seerr.s  to  be  some  probability  of  a  Pennsylvania  contact, 
as  two  220-Mc.  stations  are  being  built  by  York-area  hams. 
W4HHK,  Collierville,  Tenn.  —  After  more  than  a  year 
of  almost  daily  observation  of  meteor-burst  signals  on  144 
Mc.  there  appears  to  be  a  lag  of  a  day  or  so  between  the 
predicted  peak  of  a  meteor  shower  and  the  maximum  results 
on  the  2-meter  schedules.  Daily  tests  with  WIHDQ  and 
W2UK  continue,  working  schedules  permitting. 

W5FPB,  Albuquerque,  N.  Mex.  —  Though  there  are 
about  40  hams  in  the  area  who  can  get  on  144  Mc,  few 
show  up  regularly  on  net.  C.d.  group  would  like  2-meter 
mobiles  for  their  communications  plan. 

W6ZD0,  Canoga  Park,  Calif. —  Nightly  transmission  on 
431.5  Mc,  2000  PST.  Receiver  for  1215  Mc.  completed, 
and  work  started  on  transmitter. 

\V7JHX,  Port  Orchard,  Wash.  —  Completed  new  a.f.c. 
system  for  10,000-Mc.  gear.  Seems  extremely  stable,  holding 
over  wide  frequency  range. 

WTJRG,  Billings,  Mont.  — Gea.T  for  432  Mc.  about 
completed,  including  4X150A  coaxial-tank  tripler,  16-ele- 
ment  array  with  plane  reflector,  and  crystal-controlled  con- 
verter with  two  lighthouse-tube  r.f.  stages.  .41so  working  on 
balanced  modulator  for  s.s.b.,  3.9  to  50.4  Mc. 

W7NV0,  Boise,  /da/to  —  Working  on  145.44  Mc.  in 
Boise  Valley  2-metcr  net. 

WOLEE,  Westboro,  Wise.  —  New  power supiily  completed; 
now  running  600  watts  on  voice.  Continuing  0745  skeds 
witli  W0BBN,  but  2130  sked  discontinued.  OBS  transn  is 
sions  niglitly,  except  Monday  and  Friday,  as  follows:  west 
—  1955;  southeast  —  2000.  Frequency  —  144.12  Mc.

first  YL  to  receive  membership  in  the  Quarter  Century 
Wireless  Assn.,  thus  honoring  her  25  years  of  amateur 
activity.  From  a  start  with  a  15-watt  If artiey  rig  and  a 
Silver-Marshal!  receiver,  Vi  8GJX  has  progressed  to  a 
400-watt  TVI-suppressed  transmitter  and  assorted 
fixed-station  and  mobile  gear.  Besides  being  an  active 
operator,  Helen  is  the  mother  of  sons  WSQFD  and 
W8UED,  a  "variegated  hobbyist,"  and  a  career  woman. 
Author  of  several  books,  including  Sim  Barton,  Girl 
Radio  Operator  (story  of  a  young  girl's  determination  to 
achieve  success  as  a  First  Class  ship's  radio  operator), 
Helen  is  pictured  at  the  console  of  station  WE.SK,  NBC, 
Escanaba,  Mirh.,  where  she  is  continuity  director  and 
supervisor  of  women's  activities.  W8GJX  maintains 
that  her  many  amateur  experiences  have  directly  stim- 
ulated her  other  pursuits  and  interests.

ANTENNA    MATCHING    COIL 


Have  you  wondered  where  you  could  secure  the  Balun 
coils  referred  to  in  the  December,  1953  issue  of  QST  and 
in  the  ARRL  handbook?  If  so,  you  probably  have  a  need 
for  a  matching  transformer  to  couple  the  300  ohm  line 
from  your  antenna  to  the  75  ohm  input  on  your  converter. 
Or  does  your  present  setup  involve  lengths  of  Co-ax  to 
satisfy  this  requirement?  Or  even  worse,  are  you  just 
guessmg  and,  as  a  result,  losing  that  weak  signal  in 
the  mismatch?  A  proper  match  will  insure  the  best  oper- 
ation from  your  converter,  and  thus  those  weak  DX 
openings  can  be  turned  into  QSL  cards  rather  than  a 
station  you  were  unable  to  identify.  Whether  you  operate 
on  50,  144,  or  220  Mc  you  can  be  sure  of  a  uniform 
match  over  these  bands  without  any  tuned  circuits. 
Two  of  these  small  coils  less  than  2"  long  and  Va"  in 
diameter  will  clean  up  your  shack  by  replacing  feet  of 
Co-ax  with  a  small  4  to  1  impedance  matching  trans- 
former. Wound  on  threaded  ceramic  form.

phrase  and  mentally  repeat  it  two  or  three  times 
before  going  on  to  the  next  phrase.  Of  course,  if 
the  receiving  station  is  using  a  typewriter  you 
can  speak  more  rapidly.  A  number  of  voice 
operators  have  learned  through  experience  how 
to  prolong  certain  syllables  and  add  certain 
"niceties"  to  make  the  words  more  intelligible. 
Proper  enunciation  of  numbers  is  vital  since  they 
occur  so  frequently  in  te.xts  of  emergency  traffic 
as  well  as  in  addresses  and  telephone  numbers. 
Recommended  phonetic  substitutes  used  only 
when  required  can  be  of  tremendous  value. 

Stick  to  Business 

During  net  operations  all  communications 
should  be  limited  to  the  serious  business  at  hand; 
rag  chewing  and  nonpertinent  discussions  should 
be  eliminated.  All  transmissions  must  be  aimed 
toward  moving  the  traffic  on  to  its  destination. 

The  pamphlet  "Operating  an  Amateur  Radio 
Station,"  published  by  the  ARRL,  is  required 
reading  for  every  active  ham.  It's  available  on 
request  and  without  charge  to  League  members 
and  to  others  for  twenty-five  cents.  The  chapters 
on  Emergency  Communications,  Message  Han- 
dling and  Network  Organization  are  especially 
pertinent  to  the  present  subject. 

In  conclusion: 

Listening  and  a  silent  transmitter  are  often 
more  important  and  more  helpful  than  trans- 
mitting. 

Training  and  familiarity  with  standard  pro- 
cedures are  basic  requirements  for  helpful  par- 
ticipation. 

Net  Discipline  and  compliance  with  orders 
from  the  established  net  control  station  are 
essential  to  best  success  of  the  amateur  effort. 

Accuracy  and  exactness  in  both  transmission 
and  transcription  of  messages  is  more  important 
than  speed  for  speed's  sake. 

Participation  in  an  emergency  net  imposes 
responsibilities  beyond  reporting  in  with  an 
offer  to  help  and  then  leaving  the  net  at  will.

LOAD   RESISTANCE 

Although  values  taken  from  the  chart  in  De- 
cember QST  will  not  be  theoretically  correct,  it  is 
doubtful  whether  a  design  based  on  them  will 
show  a  material  improvement  in  actual  perform- 
ance if  the  values  are  corrected  to  conform  with 
the  accompanying  chart.  This  is  because  there  is 
wide  latitude  in  the  selection  of  a  frequency  in 
the  first  place,  and  because  it  is  difficult  to  obtain 
the  exact  values  of  inductance  and  capacitance 
called  for  in  the  ideal  case.  In  other  words,  use 
the  chart  herewith  if  you're  starting  out  fresh, 
but  don't  worry  about  the  performance  of  a  filter 
already  built  from  the  December  data. 


In  an  editor's  note  in  the  correspondence  col- 
umn on  page  138  of  the  January  issue,  reference 
was  made  to  the  ARRL  Safety  Code.  The  code 
was  published  in  the  issue  for  June,  1953,  not 
1952  as  stated. 


Re  the  circuit  diagram  of  W6RET's  crystal- 
controlled  converter  on  page  34  of  the  December 
issue,  the  positive  175-volt  supply  should  be 
connected  at  C3,  rather  than  C7,  so  that  the  volt- 
age to  the  6J6  will  be  reduced.

HAM-ADS 


(1)  Advertising  shall  pertain  to  radio  and  shall  be  of 
nature  of  interest  to  radio  amateurs  or  experimenters  in 
their  pursuit  of  the  art. 

(2)  No  display  of  any  character  will  be  accepted,  nor  can 
any  special  typographical  arrangement,  such  as  all  or  part 
capital  letters  be  used  which  would  tend  to  make  one  adver- 
tisement stand  out  from  the  others.  No  Box  Reply  Service 
can  be  maintained  in  these  columns. 

(3)  The  Ham-Ad  rate  is  iOi  per  word,  except  as  noted  in 
paragraph  (6)  below. 

(4)  Remittance  in  full  must  accompany  copy.  No 
cash  or  contract  discount  or  agency  commission  will 
be  allowed. 

(5)  Closing  date  for  Ham-Ads  is  the  20th  of  the  second 
month  preceding  publication  date. 

(5)  A  special  rate  of  70  per  word  will  apply  to  adver- 
tising which.  In  our  judgment,  is  obviously  non- 
commercial in  nature,  and  is  placed  and  signed  by  a 
member  of  the  American  Radio  Relay  League.  Thus, 
advertising  of  bona  fide  surplus  equipment  owned,  used  and 
for  sale  by  an  individual  or  apparatus  offered  for  exchange  or 
advertising  inquiring  for  special  equipment,  if  by  a  member 
of  the  American  Radio  Relay  League  take  the  Ji  rate.  An 
attempt  to  deal  in  apparatus  in  quantity  for  profit,  even 
if  by  an  individual,  is  commercial  and  all  advertising  by 
him  takes  the  .?0(S  rate.  Provisions  of  paragraphs  (1),  (2) 
and  (5),  apply  to  all  advertising  in  this  column  regardless 
of  which  rate  may  apply. 

(7)  Because  error  is  more  easily  avoided,  it  is  re- 
quested signature  and  address  be  printed  plainly. 
Typewritten  copy  preferred. 

(8)  No  advertiser  may  use  more  than  100  words  in  any 
one  issue  nor  more  than  one  ad  in  one  issue. 


Having  tnade  no  investigation  of  the  advertisers  in  the  classified 
columns,  the  publishers  of  QST  are  unable  to  vouch  for  their 
integrity  or  for  the  grade  or  character  of  the  products  or  services 
advertised.

How  to  select  a  tube  for  single  sideband 


lo  realize  the  advantages  of  Single  Sideband 
operation,  there  are  two  important  points  to  keep 
in  mind  when  selecting  a  final  amplifier  tube. 
First,  since  there  is  no  continuously  running  car- 
rier, high  peak  powers  may  be  reached  when  a 
signal  is  put  on  the  air.  And  second,  because  it  is 
easier  to  produce  an  SSB  signal  at  a  low  power 
level,  it  takes  more  than  an  ordinary  tube  to  build 
this  valuable  low  power  signal  from  the  modulator 
to  high  power  in  a  single  amplifier  stage.  Eimac 
tubes  offer  these  extras.  Their  reserve  supply  of 
filament  emission,  lack  of  internal  insulators  and 
widely  recognized  ability  to  handle  high  peak  pow- 
er has  been  proved  over  the  years.  And  high  power 
gain  is  inherent  in  all  Eimac  multi-grid  tubes.  When 
planning  or  building  an  SSB  rig,  remember  these 
two  important  points  and  consider  the  Big  Six  of 
Amateur  Radio-Eimac  4-65A,  4-125A,  4-250A, 
4-400A  and  4X150A  radial-beam  power  tetrodes 
and  the  4E27A  radial-beam  power  pentode.

For  example,  look  at  the  final  amplifier  of 
Johnson's  Viking  II.  Two  RCA-6146  beam  power 
tubes  in  parallel  deliver  a  signal  wallop  that  is 
making  history  in  the  amateur  bands. 

Here's  why  this  well-known  power  type  is  so 
popular:  RCA-6146  delivers  fiall  power  at  rela- 
tively low  plate  voltage.  RCA-6146  has  high  power 
sensitivity  (a  6AQ5  doubler/ buffer  drives  it). 
RCA-6146  operates  with  high  efficiency  —  on  all 
bands  of  this  transmitter. 

Preferred  by  radio  amateurs— ^«^  by  commercial 
transmitter  designers— RCA  high-perveance  beam 
power  tubes  and  triodes  are  available  in  a  wide 
choice  of  input  ratings.  Your  RCA  Tube  Distribu- 
tor handles  the  entire  line.  For  tube  technical  data,

All  G-E  Tubes  get  individual  tests 
to  assure  maximum  dependability! 


QUALITY-CONTROL  sampling  isn't 
enough — though  G-E  standards 
for  this  lead  the  industry.  Every  Gen- 
eral Electric  tube  is  checked  for  im- 
portant operating  characteristics. 

Instrument  dials  say  if  the  tube  plate 
current  is  correct  ...  if  transconduct- 
ance  equals  the  prescribed  value  ...  if 
no  undesirable  reverse  current  flows 
in  the  grid  . . .  if  there  is  no  tube  short, 
open  circuit,  or  vacuum  leak. 

G-E  tubes  that  pass  these  individual 
tests,  must  run  the  gauntlet  of  quality- 
control  checks  for  over-all  satisfactory 
performance.  Are  microphonics  at  a 
minimum.'  Does  life-testing  leave  tube 
characteristics  unchanged.**  Only  if  the 


answers  to  these  and  many  other  ques- 
tions are  "yes"  can  G-E  tubes  be  car- 
toned and  shipped. 

The  tubes  your  G-E  tube  distributor 
sells  are  the  best  that  precision  manu- 
facture, rigid  inspection,  and  thorough 
testing  can  produce.  Install  them  with 
confidence!  General  Electric  Co.,  Tube

1954  Edison  Award,  Benjamin  S.  Hamilton,  W6VFT, 
La  Mesa,  California.  The  judges  named  Mr.  Hamil- 
ton as  the  amateur  whose  achievement  was  most 
noteworthy,  because  he  provided  San  Diego  County, 
California,  with  "an  outstanding  Civil  Defense  and 
disaster-emergency  radio  network".  Recognition 
given  to  Award-winner  W6VFT  and  to  others  whom 
the  judges  cited,  was  equally  a  tribute  to  the  public- 
spirited  efforts  of  radio  amateurs  everywhere.

75A-4    Receiver 


for  NEW  EASE  in  OPERATION 

The  new  Collins  75A-4  Receiver,  32W-1  Exciter,  and  the  KWS-1 
Kilowatt  Transmitter  are  expressly  designed  for  SSB,  AM  and  CW. 
Like  all  Collins  Amateur  equipment,  they  meet  the  same  high  standards 
as  Military  and  Commercial  equipment. 

The  75A-4  Receiver  features  passband  tuning,  AVC  on  SSB, 
bridged  T  rejection  notch  filter,  built-in  crystal  calibrator  circuit, 
separate  detectors  for  AM  and  SSB,  a  new  noise  limiter,  and  provision 
for  three  Mechanical  Filters  together  with  time-proven  features  such 
as  good  image  rejection,  and  an  accurate  linear  dial  with  calibration 
of  1  kc  per  division. 

Transmitter  features  include  a  SSB  generator  using  Collins  Me- 
chanical Filters,  selectable  sideband,  band  switching  from  3.5  to  30 
mc,  voice  control  or  push-to-talk,  automatic  load  control,  and  dual 
conversion  with  crystal  controlled  high-frequency  oscillator  and 
stable,  linear,  permeability-tuned  low  frequency  oscillator  resulting 
in  a  linear  dial  similar  to  the  75A-4  Receivers. 

Power  input  is  one  kw  peak  envelope  power  on  SSB,  one  kw  on 
CW,  and  equivalent  to  one  kw  AM  when  received  on  narrow-band- 
width receiver. 

Several  versions  of  the  transmitting  equipment  are  available. 
The  32W-1  Exciter  is  capable  of  driving  a  kw  linear  amplifier.  With 
exception  of  the  power  supply,  which  is  housed  in  a  separate  cabinet, 
it  is  complete  in  a  receiver-type  cabinet  and  can  be  converted  into  a 
KWS-1.  The  KWS-1  is  also  complete  in  a  receiver-type  cabinet  except 
for  power  supplies,  which  are  mounted  in  an  attractive  desk-high  | 
cabinet.  As  an  alternate,  the  KWS-1  is  available  without  the  high 
voltage  power  supply  as  type  number  KWS-IK,  and  kits  are  available 
for  converting  a  32W-1  or  a  KWS-IK  into  a  KWS-1. 

Amateur  net  prices  are  as  follows: 

32W-1     Exciter    complete    ?    895.00 

KWS-1     Tronsmltter    complete    $1,995.00 

KWS-IK  Transmitter   less   H.V.   power  supply  end   P.A.   tubes $1,225.00 

428A-2  H.V.   Power  supply   kit  for  KWS-IK ?    545.00 

428A-1    Power  supply  for   KWS-IK,  wired   ond   tested ?    700.00  j

^^^  AMERICAN 
RADIO  RELAY 
LEAGUE,  INC., 

is  a  noncommercial  association  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
advancement  of  the  radio  art  and  of  the  public  welfare,  for  the 
representation  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  incorporated  association  without  capital  stock,  chartered 
under  the  laws  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu^ 
facture,  sale  or  rental  of  radio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amoteur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited.  A  bona  fide 
interest  in  amateur  radio  is  the  only  essential  qualification;  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  gronted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the,  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us..." 


MOBILE 
SIGNING 

The  receipt  of  several  inquiries  on  the  sub- 
ject prompts  us  to  discuss  some  as[)ects  of 
signing  procedures  when  operating  mobile  in 
aircraft  or  on  board  ship.  Apparently  many- 
amateurs  assume  that  any  station  aboard  an 
aircraft  is  "aeronautical  mobile,"  and  any  sta- 
tion aboard  a  vessel  is  "maritime  mobile." 
Not  so,  at  least  as  far  as  amateur  call  sign 
identification  procedures  are  concerned. 

AMien  operating  in  one  of  the  ten  P'CC  di.s- 
tricts  —  that  is,  within  the  continental  limits 
of  the  United  States  —  an  amateur  mobile 
station  in  an  aircraft  or  on  board  ship  signs  its 
call  in  precisely  the  same  manner  as  any  other 
amateur  mobile  station  such  as  one  in  an  auto- 
mobile. For  example,  a  station  in  an  aircraft 
flying  over  ^^'isconsin  would  sign,  on  c.w., 
"de  W3XXX,  9."  On  'phone,  it  would  identify 
itself  as  "This  is  W3XXX  mobile  over  Madi- 
son, Wisconsin."  An  amateur  station  aboard 
a  boat  in  New  York  Harbor  would  sign  "/2" 
or  "mobile  in  New  York  Harbor." 

Only  amateur  stations  operating  outside  the 
continental  limits  of  the  United  States  use  the 
terms  "aeronautical  mobile"  and  "maritime 
mobile"  as  part  of  the  i-equired  call  sign 
identification.  It  follows  that  such  terms  should 
be  encountered  onh'  in  the  21-  and  2S-Mc. 
bands,  such  being  the  maximum  permitted 
U.  S.  amateurs  outside  our  country.  Example: 
An  amateur  station  on  an  aircraft  en  route  to 
Europe  would  sign,  on  c.w.,"deW3XXX  AM." 
At  the  end  of  the  contact,  it  would  also  indicate 
the  number  of  the  aircraft  and  the  approximate 
geographical  location,  e.g.,  "de  W3XXX  AM 
NC417o2  3000  MI  E  OF  NEW  YORK  NY." 
On  board  ship  on  the  high  seas,  the  c.w.  sign 
would  be  "de  W3XXX  MM,"  or  at  the  end 
of  the  contact:  "de  W3XXX  MM  SS  FLY- 
ING GULL  40  W  45  N."  On  'phone,  the  same 
data  would  be  conveyed  in  the  signature. 

The  point  of  all  this  is,  however,  that  ama- 
teur mobile  stations  within  the  continental 
limits  of  the  U.  S.  sign  in  exactly  the  same 
manner  whether  thej^  are  being  operated  from 
an  automobile,  aircraft,  a  small  boat,  ocean 
liner,  or  a  bicycle. 


BEST 
SELLERS 

Even  in  the.se  days  of  billions  and  trillions, 
a  little  ol'  million  is  still  a  pretty  substantial 
figure.  It  is  especially  so  when  one  is  speaking 
not  of  Government  moneys,  but  of  publication 
sales.  And  it  becomes  a  strikingh'  large  figuie 
when  it  represents  the  sale  of  a  i)ami)hlet  in 
a  field  as  comparatively  limited  as  amateur 
radio. 

Yet  The  Radio  Amateur's  License  Manual 
has  just  sold  its  millionth  copy.  How  to  Become 
a  Radio  Amateur  has  topped  the  half-milfion 
mark,  and  Learning  the  Radiotelegraph  Code  — 
the  thirtl  and  newest  in  the  "Gateway  to 
Amateur  Radio"  series  ARRL  has  available  for 
newcomers  —  is  almost  to  the  quarter-million 
mark.  The  ARRL  Antenna  Book  is  well  over 
a  quarter-million;  A  Course  in  Radio  Funda- 
mentals is  pushing  200,000  with  Hints  ti'  Kinks 
not  far  behind.  Any  way  you  look  at  it,  these 
League  publications  have  earned  the  title  of 
"best  sellei-s." 

Time  was  when  QST  was  the  only  League 
publication.  In  1926,  the  first  Handbook  ap- 
peared;  as  its  sales  now  ai)proach  the  3,000,000 
mark  we  can  laugh  at  our  concern  —  although 
it  was  a  deadlj'  serious  problem  at  the  time  — 
whether  the  initial  printing  of  5,000  copies 
could  ever  be  sold  before  the  text  became 
obsolete! 

But  that's  another  story.  In  late  1929  the 
League  decided,  as  one  means  to  increase  its 
membership,  to  promote  interest  in  amateur 
radio  on  the  part  of  potential  newcomei-s.  So 
Hq.  got  up  a  little  pamphlet  briefly  outlining 
what  amateur  radio  had  to  ofTer  as  a  hobby, 
giving  constmctional  details  on  a  160-meter 
two-tube  (20L\s)  regenerative  detector  and 
one-stage  audio  receiver  and  a  L"X  210  t.n.t. 
transmitter  of  about  thirty  watts,  and  some 
brief  dope  on  how  to  learn  the  code  and  get 
licenses.  It  was  given  the  title  How  to  Become  a 
Radio  Amateur  and  thus — just  twenty-five 
years  ago  —  became  the  first  ARRL  booklet. 
Intended  stricth'  as  a  promotional  piece,  it 
was  nominal!}'  priced  at  a  dime,  wliich  went 
mostly  for  postage  and  handling.  Distributed 
through  newsstands  and  from  advertising  in 


Normally  prottv  cheerful  gu>  s  anyway.  General  Man- 
ager A.  L.  Budlong  and  Circulation  Manager  David  H. 
Houghton  have  good  reason  for  these  wide  grins  —  the 
millionth  copy  of  ARRL's  Lirense  Manual. 

boys'  and  home  mechanic  magazines,  it  en- 
joyed an  immediate  success. 

So  much  so,  in  fact,  that  a  couple  of  years 
later  a  new  edition  was  brought  out  with  some- 
what more  elaborate  treatment.  At  about  the 
same  time,  in  response  to  a  growing  demand, 
the  League  produced  a  20-page  compilation  of 
hcensing  information  and  some  questions-and- 
answers  for  the  amateur  exam  —  which  of 
course  became  the  License  Manual.  A  QST 
editorial  of  the  date  (1933)  announced  their 
appearances  this  way : 

In  addition  to  QST  and  the  Handbook  the 
League  has  produced  this  year  a  couple  of  book- 
lets which  we  believe  will  be  found  most  instruc- 
tive and  valuable.  We  intend  before  the  year  is 
out  to  produce  a  few  more  in  a  series  which  is 
now  getting  sufficiently  extensive  to  be  called 
a  "Radio  Amateur's  Library."  One  of  the  im- 
portant functions  of  ARRL  is  to  make  absolutely- 
reliable  information  available  to  its  members 
at  nominal  cost.  In  preparing  these  booklets  it 
will  be  our  policj-  to  select  subjects  upon  which 
further  light  is  badh^  needed,  to  give  them 
complete  treatment  to  an  extent  impossible  in 
the  pages  of  QST  or  the  Handbook,  and  to  sell 
them  at  nominal  prices. 

How  could  we  put  it  any  better  today?

Yes  —  they're  different!  Here  are  the  symbols 
that  will  appear  in  QST  starting  with  this  issue. 
The  objective  is  to  standardize,  modernize,  and 
simplif}^  circuit  symbolization.  The  American 
Standard  symbols  shov^^l  required  five  years  of 
preparation.  Those  participating  in  this  task 
included  representatives  of  industry,  govern- 
ment, and  publishing.

QST  for 


The  All-Electronic  TJltimatic"  Keyer 

Part  I —  Construction  and  Handling 
BY  JOHN  KAYE,*  W6SRY 


THE  SELECTION  two  j'ears  ago  of  "Ultimatic" 
as  a  name  for  "a  key  with  a  memory"  was 
a  bit  premature.^  Reversion  to  the  hoary 
twin-lever  key  and  the  addition  of  sequence 
"seizure"  now  eUminates  most  of  the  back-and- 
forth  motion  normal!}'  associated  with  code 
transmission,  carrying  the  principle  much  closer 
to  the  ultimate. 

The  new  sequencing  function  piovides  leeway 
for  key  release  corresponding  to,  and  greatly 
exceeding  in  time,  the 
leeway  for  key  closure 
provided  by  advance 
storage  in  the  memory 
circuits.  It  also  reduc^es 
the  maximum  back- 
and- forth  motion  of  the 
hand  to  once  per  letter, 
and  that  at  a  givatly 
reduced  rate.  On  most 
letters  the  rocking  mo- 
tion is  completely  ciini- 
inated.    By    obviating  .»,       j 

the    fight    against    the  %'**^ 

hand's  inertia,  the  ef-  ■«.'*!»**.    f 

fort  expended  for  any 
given  speed  is  great  l.\' 
reduced.  Besides  re- 
lieving the  operator  of 
virtually  all  timing  re- 
sponsibilities, and  most 

of  the  labor,  the  com-  .,       .  n    i    .

with    all     sensation     of        the   muhiple-relay    version 
being  chained  to  an  in-       ''"^  "•■"»•■■  version, 
exorable  time  base. 

The  time  base,  nienioiy,  ami  interlocked- 
sequencor  circuits  handle  automatic  spacing  and 
advance  storage  of  marking  characteis  in  a 
manner  functionally  identical  to  the  relay  motlel. 
(The  original  article  is  recommended  rereading  in 
conjunction  with  a  detailed  study  of  this  im- 
proved model.)  With  twin  keys  and  the  new 
seizure  circuitry,  continuous  closure  of  one 
key  generates  that  tjpe  of  character  until  the 
opposite  key  is  also  closed.  After  completion 
of  the  character  in  progress,  the  output  switches 
to  the  opposite  tA'pe,  even  with  both  keys  closed. 
Release  of  either  key  provides  output  correspond- 
ing to  the  still-closed  key.  With  one  key  held 
closed,  a  single  opposite-type  character  can  be 
injected  by  a  closure  (as  short  as  2  microseconds) 
of  the  opposite  ke\-  at  any  time  after  the  start  of 
a  desired  preceding  character. 

*  2296  West  Nicolet,  Banning,  Calif. 

'  Kaye,  "Tlie  'Ultimatic'  —  a  Key  with  a  Memory," 
QST,  February,  1953. 


Multiple  intermediar\'  opposite-type  characters 
within  a  letter  are  obtained  by  holding  one  key 
closed  throughout  the  entire  letter  while  operat- 
ing the  opposing  key  long  enough  in  the  middle 
of  the  letter  to  get  the  desired  string.  When  both 
ke\"S  are  released  together,  the  terminal  char- 
acter(s)  is  determined  bj-  the  lastly-closed  key. 
When  the  keys  are  released  independently,  the 
terminal  character(s)  is  selected  by  the  still- 
closed  key. 

Using  the  Key 

One  can,  of  course, 
attack  the  keyer  as  if  it 
were  an  ordinarj'  bug 
or  start -stop  automatic 
key,  or  with  any  inter- 
mediate technique  up 
to  that  realizing  full 
usage  of  all  functions. 
Since  a  given  key  need 
not  be  released  to  per- 
mit selection  of  an  op- 
posite-type character, 
the  motions  on  the 
ke>s  ma.\'  be  as  careless 
as  the  mood  dictates, 
with  all  kinds  of  over- 
laj).  The  one  and  onli/ 
lequirement  is  that  the 
two  keys  be  closed  in 
the  proper  order  for  the 
letter  being  sent.  The 
output  comes  up  straight 


version  of  the  "key  with  a 
Several  improvements  over 
ha\e   been    ineorporatetl   in 


and  perfect. 

A  few  specific  exam- 
jjles  of  full  siHiucncor  u.sage  are  in  order;  otherwise 
an  operator  might  never  discover  the  really  easy 
way  to  make  a  CQ,  a  numeral  or,  for  that  matter, 
any  of  the  combinations.  For  the  call  '  WlAW," 
both  keys  may  be  squeezed  together  four  times, 
each  time  allowing  the  dot  side  to  close  at  le^t  a 
few  microseconds  before  the  dash  side.  Thej'  are 
both  held  at  least  until  the  last  dash  of  each  letter 
starts,  and  they  are  necessarily  released  between 
letters  only  long  enough  to  establish  automatic 
interletter  spacing.  "W6BJ"  calls  for  similar 
technique,  with  the  dash  key  making  first 
contact  on  the  "6"  and  the  "B." 

A  question  mark  results  most  easilj'  from 
continuous  closure  of  the  dot  key  for  the  entire 
duiation,  with  the  dash  key  operated  any  time 
(luring  the  second  dot.  The  dash  key  is  released 
an>'where  from  the  start  of  the  second  dash 
up  to  due  time  for  the  first  terminal  dot.  The 
reverse  procedure  gives  a  comma.  A  numeral

after  the  third  dot  starts.  Both  keys  may  be  re- 
leased together  any  time  after  the  beginning  of 
the  second  dash,  or  independently. 

That  bearcat  "CQ"  is  a  pushover:  continuous 
closure  of  the  dash  key  throughout  each  lettei-, 
with  the  dots  flicked  in  indiscriminately,  taking 
full  advantage  of  the  memory  leeway.  The  "C" 


can  be  started  with  the  "squeeze"  technique,  or 
it  can  be  made  with  two  quick  squeezes  just  long 
enough  to  trip  the  memories.  This  is  true  for  cum 
combination  whose  first  two  characters  are  of  op- 
posite type.  In  context,  a  given  letter  will  nor- 
mally be  manipulated  differentl\'  between  differ- 
ent preceding  and  following  comV)inations,  to 
minimize  seesaw  motion.  All  code  combinations

General  Circuit  Data 

As  the  circuit  diagram  '  in  Fig.  1  shows,  power 
is  derived  from  line-tj'pe  rectifiers.  The  tube 
heaters  are  in  series  across  the  line.  Alternatively, 
the  heaters  can  be  fed  in  parallel  or  series-parallel 
from  a  suitable  transformer.  The  plate  and  l)ias 
voltages  are  ol)tained  from  a  11 7- volt  40-ma. 
winding,  or  they  can  be  borrowed  from  an  avail- 
able source  via  VR  tubes.  The  NE-32  maintains 
constant  relay  current  for  stable  mark-to-spac(> 
ratio  at  all  line  voltages.  An  isalation  trans- 
former is,  of  course,  mandatory  unless  the 
station  is  designed  for  "hot-line"  operation 
throughfjut,  through  the  use  of  ajipropriatc 
Siifety  grounding, 

For  long  tube  life,  maximum  plate  current  in 
most  tubes  runs  around  13 '  2  ma.,  although  some 
tubes  draw  less  than  '2  nia.  The  pulse  i)eak  in 
V'2  hits  6  ma.  The  keyer  is  completely  stal)Ie 
with  line  voltages  from  80  to  135,  but  it  goes 
berserk  if  too  much  r.f.  gets  back  to  it  through 
external  leads.  Voltages  mentioned  for  various 
|)oints  in  the  circuit,  as  measured  with  a  v.t.v.m., 
obtain  with  average  tubes  and  10-per-cent- 
tolerance  components  at  113  line  volts  and  —33 
volts  bias. 

Construction 

This  particular  unit  was  l)uilt  in  a  Channel- 
Lock  box  cut  down  to  4  by  4  by  3  inches.  The 
moimting  plate  fastened  to  the  front  panel  section 
provides  Jg  inch  below  for  components  and 
23-1  fi  inches  above  for  tubes.  .\11  surfaces  except 
the  front  are  i)erforated  with  i/g-i'X'h  ventilation 
holes  on  34-inch  centers,  with  additional  ''1  (j-inch 
access  holes  in  the  bottom  for  /?:j  and  li^. 

To  minimize  bulk,  the  CK-5829  subminiature 
diodes  and  the  NE-32  are  wired  direct  without 
sockets.  If  12AL5s  are  substituted  for  the  ex- 
pensive subminiature  diodes,  with  relay  output, 
the  housing  depth  reciuirement  is  4%  inches  for 
another  row  of  tubes.  With  electronic  output  in- 
stead of  the  relay,  the  two  additional  potentiome- 
ters can  be  stacked  above  R3  and  /?5,  with  top- 
side access,  and  the  NE-32  can  be  eliminated.  It 
is  entirely  feasible,  of  course,  to  provide  room  for 
three  12AL5s  by  reducing  the  size  of  the  keys. 
Subminiature  potentiometers  would  then  occupy 
the  space  below  the  chassis  vacated  bj^  the 
CK5829S. 

Further  reduction  of  over-all  size  is  not 
recommended.  The  thing  already  runs  hotter 
than  the  proverbial  two-buck  pistol,  with  the 
present  amount  of  compression.  On  the  contrary, 
one  should  reallj'  spread  it  out  in  a  big  box 
or   rack   mounting,    bringing   out   the   key   and

a  socket  orientation  providing  optimum  compo- 
nent dress,  with  resistors  mounted  on  and  be- 
tween the  sockets.  All  No.  9  pins  and  center 
shields  were  removed  to  provide  more  room  for 
parts.  With  the  heaters  connected  in  parallel 
for  6.3-volt  operation,  the  No.  9  pins  should  be 
bent  over  and  soldered  to  the  mounting  rings. 
If  the  series  heater  connection  is  used,  the 
heater  leads  should  be  dressed  very  tightly 
against  the  chassis,  to  minimize  a.c.  fields. 

Fig.  2B  shows  a  side  view  of  the  key  levers. 
Although  a  cone  pivot  bearing  is  definitely 
superior,  the  threaded  bearing  pivots  in  this 
unit  proved  surprisingly  good,  and  they  can 
be  readily  built  with  a  minimum  of  effort.  The 
keys  are  assembled  on  a  13^  X2X  }  i  e-inch  metal 
plate,  insulated  from  the  chassis  by  ^.s-inch 
Plexiglas  levers  and  threaded  on  the  8-32  pivot 
bolts.  (Metal  pivot  blocks,  tapped  for  8-32,  are 
bolted  to  the  ^'-inch  Plexiglas.)  The  pivot 
bolts  are  secured  to  the  key  plate  with  nuts, 
as  shown.  The  "spring"  tension  is  adjusted  by 
sliding  the  rubber  band  to  an  appropriate  i)osi- 
tion.  This  method  of  supplying  spring  tension 
absorbs  most  of  the  sloppiness  that  might  result 
from  too  loose  a  thread  fit  in  the  pivot  screws,  a 
condition  apt  to  arise  from  filing  threads  to 
eliminate  bindintr. 


During  construction  of  the  many  miniaturized 
models  preceding  this  one,  it  was  found  wise  to 
wire  subcircuit  by  subcircuit,  performance  check- 
ing each  subcircuit  before  going  on.  Nothing  is 
so  exasperating  as  finding  a  bonehead  error 
buried  under  three  layers  of  resistors  massed 
together  with  J^-inch  leads.  Ask  me  —  I  know! 

Trigger  &  Bias  Adjustment 

The  sole  adjustment  procedure  consists  of 
running  the  bias  up  and  down  at  R^  with  various 
line  voltages  between  80  and  135,  to  find  the 
range  of  stable  operation  for  each  functional 
circuit.  At  each  test  setting,  check  over-all  opera- 
tion and  each  circuit  individually  with  a  v.t.v.m., 
in  accordance  with  the  functional  summaries.^ 
Observation  of  circuit  performance  can  be  greatly 
simplified  by  slowing  things  down  to  a  walk  with 
0.25  /if.  (metallized,  to  minimize  leakage)  shunted 
across  C'l  of  Fig.  1,  so  that  the  v.t.v.m.  needle 
stands  still  long  enough  to  be  read.  Approximate 
expected  voltages  are  given  in  the  circuit  descrip- 
tion. Others  are  readily  calculated  from  the  di- 
vider strings,  bearing  in  mind  grid-loading  effects. 
With  normal-tolerance  components,  it  is  to  be  an- 
ticnpated  that  one  or  two  of  the  subcircuits  may 
turn  up  with  a  bias  range  centering  somewhat 
off  the  median  value.  The  addition  of  a  2-  to  4- 
megohm  shunt  across  the  appi-opriate  element  of 
the  resistance  string  will  pull  the  range  center 
to  median.  The  final  setting  of  Ri,  is  at  the  average 
of  the  l)ia.=i-i;inge  midpoints  for  all  the  subcir- 
"  cuits  at  expected  nominal  line 
voltage. 

Tube  and  component  aging 
IS  compensated  at  Rh,  though 
readjustment  will  not  be  re- 
([uiretl  until  prolonged  aging 
has  drastically  shifted  the 
tolerance  midpoints.  The  model 
shown  here  tolerates  a  ±5-volt 
bias  sliift  from  the  — 33-volt 
median  establishetl  at  a  nomi- 
nal 1 13  line  volts.

mum dot  speed  the  relay  spring  tension  is 
adjusted  for  midscale  on  the  ohmmeter.  Steads-

adjustments  interact  a  bit,  so  two  or  three  runs 
may  be  necessary  to  establish  a  constant  mark/

R2  is  set  last,  with  i?i  at  minimum,  for  the  desired 
top  speed.

plate  current.  7^2  of  Fig.  1  is 
trimmed  for  the  top  speed. 

Test  Equipment 

It  must  lie  remembei'ed 
that  the  only  test  equipment 
that  can  possibly  be  used  to 
read  manj'  of  the  voltages  in 
the  Ultimatic  is  a  v.t.v.m. 
with  an  input  impedance  on 
the  order  of  30  to  50  megohms, 
or  all  equivalent  cathode-fol- 


lower device.  Even  with  a  1-megohm  isolating 
resistor  in  the  probe,  the  triggers  will  sometimes 
be  tripped  by  capacity  as  contact  is  made.  To 
determine  which  way  a  circuit  is  stabilized,  it  is 
best  to  read  across  the  cathode  resistor,  touching 
the  grid-plate  strings  only  for  an  actual  voltage. 

Learning  To  Use  the  Key 

Trial  runs  on  guinea-pig  operators  indicate 
that  it  takes  a  little  time  to  reeducate  one's 
reflexes  so  that  at  high  speed  one  can  take  full 
advantage  of  all  of  the  sequencing  functions  and 
leewaj'  tolerances.  Full  use  of  the  seizure  function 
calls  for  a  considerable  departure  from  standard 
techniques.  However,  the  new  tricks  are  readily 
acquired  because  they  demand  much  less  effort. 
One  who  has  never  used  an3i;hing  but  a  pump 
handle  has  a  nice  advantage  and  can  master  the 
gadget  much  faster  because  he  has  no  cortical 
synapses  to  disconnect,  nothing  to  unlearn.  How- 
ever, and  this  is  the  beauty  of  the  thing,  whatever 
technique  is  being  used  on  the  present  bug  or 
start-stop  autokey  will  produce  perfect  results  at 
usual  sending  speeds  after  5  minutes  of  practice. 
Mastering  the  tricks  simply  calls  for  experimenta- 
tion, using  the  functional  summaries  and  specific 
examples  as  guides.  Every  operator  will  acquire 
his  own  personal  technique,  equally  good  but 
possibly  different.  Initial  practice  should  be  at 
low  and  moderate  speeds  to  facilitate  study  of 
the  relationships  between  the  Selector-memorj^- 
sequencor,  the  time  base,  and  the  hand. 


A  bottom  view  of  the  key

allowing  more  room  for  the

Graphical  Symbols  for  Radio  Diagrams 

Including  CriiidisihS  ©/  ''Condenser"  and  "Capacity" 
BY  HAROLD  P.  WESTMAN  * 


•  A  iieM-  American  Standard  coverinfi 
symbols  for  use  in  electrical  circuit  dia- 
jsrams  was  adopted  last  year,  and  there  is 
no>v  under  way  a  serious  effort  to  i>er- 
suade  all  users  of  such  symbols  to  make 
their  practices  conform  with  it.  The  ad- 
vantages of  having  one  universal  lan- 
guage instead  of  a  large  collection  of 
dialects  shoidd  be  obvious,  and  begin- 
ning with  this  issue  the  symbols  in  QST 
schematic  diagrams  will  be  those  of  the 
new  Standard. 


GRAPHICAL  SYMBOLS  is  the  high-brow  name 
.  for  the  drawings  that  we  use  in  circuit 
diagrams.  Originally,  they  were  crude  pic- 
tures of  actual  pieces  of  equipment  but,  to  save 
time  and  to  permit  a  drawing  to  represent  more 
than  one  manufacturer's  design  of  a  part,  the 
finer  details  were  soon  omitted  and  the  pictures 
gradually  lost  their  resemblance  to  the  actual 
equipment.  They  developed  into  symbols  rathei- 
than  pictograms.  In  practice,  this  means  that 
now  we  have  to  learn  the  meanings  of  these 
symbols  because  they  don't  look  enough  like 
the  actual  equipment  for  us  to  identify  one  from 
the  other.  Life  does  get  complicated. 

Those  of  us  who  are  interested  only  in  radio 
have  learned  quite  a  number  of  symbols  and  are 
entirely'  willing  to  go  on  using  them  until  we 
find  that  they  no  longer  suit  our  needs.  This  is 
also  true  of  people  concerned  only  with  power 
applications  of  electricity.  Unfortunately,  these 
two  groups  paid  very  little  attention  to  each 
other's  symbols  over  the  j'ears  with  the  result

that  direct  conflicts  developed  for  such  funda- 
mental units  as  indu(^tance,  resistance,  and  ca- 
pacitance. 

During  the  second  World  War,  the  armed 
forces  in  the  United  States  arranged  something 
of  the  nature  of  a  shotgun  wedding  and  both  the 
power  and  communication  engineers  agreed  "for 
the  duration  "  on  a  set  of  basic  symbols  that  did 
not  contradict  each  other.  These  were  put  in 
effect  by  QST  at  that  time. 

Unfortunately,  there  has  been  some  tendency 
on  both  sides  to  drop  back  into  our  old  habits 
and  this  was  encouraged  to  some  extent  by  the 
fact  that  the  wartime  action  concerned  only  a 
few  basic  symbols;  other  points  of  confusion 
existed  in  the  remainder  of  the  standards. 

New  Symbol  Standards 

After  several  years  of  work,  a  new  American 
Standard  '  has  been  approved  and  it  replaces 
five  previous  standards  on  electrical  graphical 
symbols.  This  single  standard  includes  symbols 
for  both  communication  and  power  drawings.  It 
contains  symbols  for  all  items  that  were  in  the 
l)revious  standards  and  many  more. 

Numerous  changes  have  been  made  so  that 
the  symbols  will  be  consistent  with  each  other 
and  while  in  some  cases  more  than  one  symbol  is 
permitted  for  a  given  item,  there  are  no  cases 
where  a  symbol  has  more  than  one  meaning. 
Thus,  the  reader  should  never  be  in  doubt  as  to 
what  the  author  intended  even  though  the  author 
may  have  had  a  choice  as  to  the  particular  foi'iu 
of  the  sv'mbol  he  would  use. 

In  general,  there  will  undoubtedly  be  a  tend- 
ency for  each  group  to  use  those  new  symbols 
that  are  most  like  the  old  familiar  forms.  In 
some  cases,  the  new  symbols  are  easier  to  draw 
and  will  be  used  for  this  reason. 

Fig.  1  shows  where  the  greatest  conflicts  were. 
The  communication  resistance  and  the  power 
inductance  were  identical  as  were  the  commu- 
nication capacitance  and  the  power  open  con- 
tacts.   Briefly,    the   power  people   gave  up   the

A  Radical  Approach  to  Single  Sideband 

Revolutionary  Ideas  for  Simplifying  'Phone  Communication 
BY  LARSON  E.  RAPP,*  WIOU 


•  Here  is  an  article  that  no  discerning 
'phone  man  can  afford  to  pass  up.  Al- 
though the  ARRL  Laboratory  staff  has 
not  had  an  opportunity  to  confirm  Mr. 
Rapp's  findings,  past  experience  with 
his  disclosures  have  shown  us  (and  our 
readers)  what  we  can  expect  from  this 
sage. 


THERE  can  be  no  question  in  the  mind  of  any 
active  radio  amateur  that  the  most  progres- 
sive step  in  the  past  pentad  has  been  the 
immediate  and  wholehearted  acceptance  of 
single-sideband  telephony.  One  has  only  to  listen 
in  on  any  of  the  low-frequency  'phone  bands  and 
hear  the  pioneers  patiently  explaining  the  virtues 
of  s.s.b.  to  the  younger  and  more  timid  amateurs 
to  realize  that  some  really  splendid  work  is  being 
done.  Many  old-timers  can  be  heard  jocularly 
referring  to  the  medium  as  "Chinese  modula- 
tion" or  "those  Donald  Ducks,"  in  an  obvious 
effort  to  put  the  newcomers  at  ease. 

However,  because  there  is  still  some  reluctance 
on  the  part  of  technically-unskilled  amateurs  to 
adopt  single-sideband  technique  and  thus  enjoy 
its  advantages,  the  author  feels  that  the  time  is 
right  to  disclose  his  latest  invention.  Although 
originally  developed  for  patent  purposes  only, 
the  invention  is  too  meritorious  to  be  withheld 
from  radio  amateurs,  who  are  always  willing  to 
try  anything  if  it  is  simple  and  cheap  enough. 
Ergo,  before  disclosing  the  invention  and  the  cir- 
cuits, it  is  well  to  review  a  few  basic  principles. 

The  generally-acknowledged  advantages  of 
single-sideband  are  greater  effectiveness  for  the 
same  total  power  to  the  transmitter,  ability  to  use 
voice-operated  break-in,  and  freedom  from  TVI. 
On  the  debit  side  of  the  ledger  are  the  use  of  un- 
familiar circuits,  inability  to  use  a.v.c.  and 
S-meter  at  the  receiver,  and  the  tendency  of 
SWLs  to  overlook  such  a  signal  in  favor  of  one  of 
the  a.m.  variety.  It  occurred  to  the  author  that 
what  was  needed  to  make  single  sideband  uni- 
versally acceptable  was  a  simplification,  both  at 
the  transmitting  and  at  the  receiving  end,  and 
this  reasoning  was  confirmed  by  consultation 
with  several  other  experts  in  this  and  allied 
fields.  Since  "a  clear  statement  of  the  problem  is 
the  first  step  toward  a  solution,"'  no  time  was 
lost  in  getting  down  to  work.  Through  fortuitous 
and  careful  design,  the  eventual  solution  also 
overcame  the  objectionable  characteristics  of 
conventional  (and  now  old-fashioned)  s.s.b.

The  Approach 

Referring  to  the  literature  on  single  sideband, 
it  is  almost  amusing  to  observe  how  blindly  one 
investigator  follows  another  in  approaching  the 
problem,  with  the  inevitable  result  that  they  have 
all  overlooked  the  very  obvious  simplification  that 
will  soon  be  disclosed.  For  example,  every  author 
starts  out  by  describing  a  double-sideband-plus- 
carrier  a.m.  signal,  and  then  laboriously  tells  of 
methods  for  first  eliminating  the  carrier  and  then 
one  sideband.  It  is  this  line  of  reasoning  that  has 
resulted  in  a  blind  spot  in  the  thinking  which, 
fortunately,  is  about  to  be  removed. 

Your  author  approached  the  problem  from 
another  tangent.  Having  observed  that  s.s.b. 
operators  still  suffer  occasionally  from  BCI  (in- 
terference to  broadcast  receivers),  and  recalling 
that  narrow-band  f.m.  is  immune  to  BCI  trou- 
bles, combining  the  merits  of  n.f.m.  with  s.s.b. 
seemed  like  a  fruitful  avenue  of  approach.  It  was, 
and  the  final  solution  was  really  too  good  to  be 
true.  It  is  being  disclosed  now  so  that  others  can 
appreciate  its  advantages. 

The  Solution 

As  all  amateurs  know,  an  f.m.  signal  is  gener- 
ated by  a  reactance  modulator  working  on  an  oscil- 
lator to  swing  the  frequency  back  and  forth  about 
a  mean  frequency  called  the  carrier  frequency.  To 
generate  a  single-si deband-f.m.  signal,  the  author 
cleverly  reasoned  that  it  was  only  necessary  to 
swing  the  frequency  on  one  side  of  the  carrier  —  on 
the  low  side  for  the  low  sideband,  and  on  the  high 
side  for  the  high,  or  upper,  sideband.  Fortunately, 
this  offered  no  great  problem,  since  part  of  the 
technique  had  already  been  disclosed  in  an  earlier 
paper.2  Hence,  the  generator  for  a  s.s.b. -f.m. 
signal  requires  only  a  speech  amplifier  of  suffi- 
cient gain,  a  "positive/negative"  modulator 
driving  a  reactance  modulator,  and  an  oscillator 
followed  by  suitable  amplifiers.  The  desired  side- 
band is  selected,  of  course,  by  switching  to  either 
the  "positive"  or  the  "negative"  modulation 
condition. 

Astute  readers  will  immediately  ask,  "But 
what  about  carrier  elimination?"  This  is  a  good 
question,  but  one  that  shows  a  lack  of  basic  un- 
derstanding of  the  system  so  far.  It  should  be 
obvious  that  the  carrier  isn't  present  while  it  is 
busy  swinging  over  the  "sideband"  portion  of 
the  spectrum,  and  hence  it  is  only  necessary  to 
eliminate  the  carrier  while  one  isn't  talking.  This  is 
not  a  difficult  problem,  and  is  solved  by  the 
method  current  in  vogue  among  the  s.s.b.  pio- 
neers; namely,  voice-operated  break-in.  By  mini- 
mizing the  "hold-in"  time,  the  carrier  is  only 
apparent  between  very  short  pauses,  and  this

slight  disadvantage  is  more  than  overshadowed 
by  the  obvious  advantages  of  the  entire  system. 
A  balanced  modulator  can  be  used,  of  course,  if 
the  ultimate  in  tube  efficiency  is  desired,  but  the 
other  method  is  the  simple  approach. 

Unlike  the  old-fashioned  s.s.b.,  this  new  system 
needs  no  carefully-designed  mixers  for  band 
changing,  since  s.s.b. -f.m.  is  like  conventional 
f.m.  in  this  respect  and  requires  onlj-  frequence- 
multiplication  for  bandchanging.  Furthermore, 
there  is  no  real  need  for  careful  adjustment  of 
linear  amplifiers  as  there  is  with  the  older  s.s.b., 
and  a  Class  C  amplifier  will  handle  a  single- 
sideband  f.m.  signal  just  as  well  as  will  a  Class 
ABi,  AB2  or  B  amplifier.  This  feature  eliminates 
the  need  for  special  bias  supplies  and  an  oscil- 
loscope, as  well  as  the  need  for  careful  adjustment 
when  shifting  frequency.  The  use  of  Class  C 
stages  throughout  results  in  the  highest  possible 
efficiency,  but  care  must  be  taken  to  prevent  the 
generation  of  high-order  harmonics  that  may 
interfere  with  TV  reception  in  the  vicinity.  As  a 
result  of  these  tolerant  parameters,  s.s.b. -f.m.  can 
be  applied  to  anj^  existing  transmitter  bj-  making 
a  few  simple  changes  in  the  oscillator.  A  block 
diagram  of  the  basic  exciter  is  shown  in  Fig.  1,

purposes.

The  Reception  0/  S.S.B. -F.M. 

The  reader  ma>'  l)e  wondeiiiig  what  must  l)c 
done  at  the  receiving  end  to  copy  a  s.s.b. -f.m. 
signal  and,  we  are  proud  to  say,  this  is  one  of  the 
delightful  aspects  of  the  system.  It  has  been 
pointed  out  on  several  occasions  that  conven- 
tional s.s.b.  is  difficult  to  tune  in  —  some  ob- 
servers report  it  is  impossible  with  a  conven- 
tional a.m.  'phone  receiver  —  but  s.s.b. -f.m. 
eliminates  any  and  all  such  troubles.  It  is  tuned 
just  like  narrow-band  f.m.  (Signal  detuned 
slightly,  to  fall  on  one  side  or  the  other  of  the 
"slope"  of  the  i.f.  characteristic.  This  is  called 
"slope  detection."  for  oiivious  reasons.)  How- 
ever, one  significant  difference  becomes  immedi- 
ately apparent,  and  it  is  one  of  the  wa\s  an 
operator  can  recognize  a  s.s.l).-f.m.  signal  in  a 
l)and  loaded  with  a.m.,  s.s.b.  and  n.f.m.  signals. 
In  the  reception  of  s.s.lx-f.m.,  if  the  receiver  is 
tuned  to  the  wrong  side  of  center,  the  speech  be- 
comes inverted,  so  there  is  actually  only  one  cor- 
rect side.  Thus  the  selectivity  of  the  receiver  is 


increased,  because  the  signal  onh'  comes  in  at  one 
spot  on  the  dial.  (Some  operators  object  to  the 
broadness  of  n.f.m.,  because  it  comes  in  at  two 
spots  on  the  dial.  However,  n.f.m.  is,  of  course,  a 
double-sideband  system,  and  the  two-spot  tuning 
is  not  so  surprising  if  jou  stop  and  think  of  it  in

this  manner.)  But,  indubitably,  the  greatest  ad- 
vantage of  s.s.b.-f.m.  over  old-fashioned  s.s.b.  is 
that  Ihe  need  for  careful  tuning  is  eliminated,  since 
the  s.s.b.-f.m.  need  only  be  tuned  on  the  correct- 
slojje  side.  There  is  no  longer  any  need  for  careful 
carrier  reinsertion!  (Remember  that  the  swinging 
of  the  carrier  is  generating  the  sideband.  The  car- 
rier has  never  been  eliminated,  hence  it  does  not 
require  reinsertion.^ 

.\i'.  ideal  receiver  i.f.  characteristic  for  s.s.b.- 
f.m.  would  be  one  that  looks  like  a  right  triangle, 
if  ever\-one  agrees  to  the  use  of  only  one  sideband 
and  whether  it  shall  l)e  the  upper  or  the  lower. 
Failing  this,  the  best  receiver  characteristic 
would  be  one  with  a  double-ramp  configuration. 
Actually,  however,  the  difference  in  performance 
lietween  the  ideal  and  a  conventional  i.f.  charac- 
teristic is  slight. 

Financial  Considerations 

Of  interest  to  the  impecuniou.s  amateur  is  the 
investment  required  for  any  new  type  of  equip- 
ment. One  of  the  criticisms  of  s.s.b.  has  been  that 
it  is  too  expensive,  since  it  wastes  the  large  audio 
tubes  and  transformers  associated  with  a  'phone 
station.  Unfortunately,  s.s.b.-f.m.  offers  no  solu- 
tion for  this  complauit,  if  one  already  has  reached 
the  legal  power  limit.  However,  it  is  suggea^'d 
that  if  one's  present  transmitter  has  not  yet 
reached  the  legal  limit  (this  varies  throughout  the 
world  and  even  within  countries),  he  may  be  able 
to  sell  his  excess  audio  equipment  to  some  hi-fi 
enthusiast  among  the  Cadillac  station-wagon  set. 

An\-  way  it  is  computed,  s.s.b.-f.m.  is  more 
economical  than  either  a.m.  or  s.s.b.  Its  effective- 
ness being  what  it  is,  practically  no  time  will  be 
spent  in  making  fruitless  calls.  And  once  QSO  has 
been  established,  it  is  practically  certain  that  no 
time  will  be  wasted  in  needless  repeats.  On  a 
strict  dollar-for-dollar  basis,  a  s.s.b.-f.m.  trans- 
mitter shows  a  47.2  per  cent  superiority  over  a 
kilowatt  s.s.b.  rig  and  a  71.4  per  cent  advantage 
over  a  kilowatt  a.m.  rig.  In  hock  Veritas.

Using  the  6360  Dual  Tetrode  on  220  Mc. 

Low-Cost  All-Tetrode  Transmitter  for  the  220-Mc.  Beginner 

BY  EDWARD  P.  TILTON,  WIHDQ,  AND  MASON  P.  SOUTHWORTH,  WIVLH 


UNLESS  one  is  content  to  get  along  with  the 
various  receiving  tubes  that  can  be  pressed 
into  transmitter  service,  firing  up  on  220 
Mc.  can  be  a  rather  expensive  proposition.  The 
832A,  surjjlus  variety,  has  been  the  only  tube 
that  would  do  the  job  at  power  levels  above  the 
receiving  tubes,  without  setting  the  purchaser 
back  a  sizable  piece  of  change.  And  now,  unless 
you  already  have  your  832a,  they  are  no  longer 
very  attractive  from  the  standpoint  of  price. 
Other  tubes  usable  at  220  Mc.  begin  at  around 
$15.00,  and  range  on  up  from  there. 

The  6360,  a  small  dual  tetrode  introduced 
recently  by  Amperex,  makes  the  220-Mc.  picture 
a  little  brighter.  It  won't  handle  quite  as  much 
power  as  its  larger  brothers,  the  6252  and  589 4 A, 
but  it  works  well  on  220  Mc.  and  it  sells  at  a  re- 
ceiving-tube price.  The  tube's  low  cost  is  largely 


variety,  to  show  newcomers  that  there  are  oscil- 
lators other  than  the  overtone  types  used  so  often 
in  recent  years.  The  tetrode  oscillator  has  an  ad- 
vantage, too:  you  can  put  in  8-  or  12-Mc.  crystals 
interchangeably.  The  oscillator  plate  circuit  may 
be  tuned  to  24  Mc.  or  36  Mc.  if  12-Mc.  crystals 
are  used,  allowing  a  choice  of  doubling  or  tripling 
in  the  second  stage. 

The  oscillator  is  a  6CL6,  as  is  the  first  multi- 
plier. Type  5763s  could  probably  be  substituted 
in  these  stages,  or  a  single  6360  can  be  used  for 
both,  if  you  want  to  standardize  on  one  tube  type. 
A  l)alanced  plate  circuit  is  used  in  the  multiplier, 
so  that  its  output  can  be  capacitively  coupled  to 
the  6360  tripler  grids.  We  insert  a  hint  at  this 
point:  If  you  run  into  trouble  with  insufficient 
grid  drive  to  the  6360  tripler,  try  putting  a  small 
plastic  trimmer  lietween  the  low  side  of  L^  and 


I'he  220-Mc.  tetrode  trans- 
mitter. At  the  right  are  the 
6CL6  crystal  oscillator  and 
multiplier  stages,  with  the  6360 
tripler  and  amplifier  in  the 
center  and  left,  respectively. 
The  rig  is  huilt  on  a  sheet  of 
aluminum  which  is  screwed  to 
an  inverted  chassis. 


the  result  of  its  single-ended  construction.  All 
connections  are  brought  out  through  the  base, 
so  it  can  be  made  on  the  same  machinery  that 
grinds  out  receiving  tubes. 

Actually,  the  6360  is  built  a  good  deal  like 
an  oversized  6J6,  with  screens  added.  A  central 
heater  and  cathode  have  pairs  of  other  elements 
on  either  side.  Compact  construction  and  short 
leads  result  in  a  tube  that  works  well  on  220  Mc, 
and  will  even  go  to  420,  in  a  pinch.  One  6360, 
tripling,  will  drive  another  as  a  straight-through 
amplifier  on  220  Mc,  and  that  is  how  the  tubes 
are  used  here. 

Transmitter  Circuit 

Circuitwise,  the  rig  described  here  is  a  depar- 
ture from  the  technique  we  have  used  in  most 
v.h.f.  transmitters  described  n^cently,  in  that  a 
conventional  t(;trode  crystal  oscillator  is  used, 
rather  than  a  triode  in  an  overtone  oscillator. 
This  switch  was  made  mainly  for  the  sake  of 


ground,  to  balance  up  the  capacitances  on  either 
side.  It  was  not  needed  in  the  original,  but  it 
would  be  well  to  remember  the  suggestion,  just 
in  case. 

The  6360  push-pull  tripler  to  220  Mc.  is  in- 
ductively coupled  to  the  push-pull  final  stage. 
No  neutralization  is  shown  in  Fig.  1.  Should 
neutralization  be  needed,  a  method  for  achieving 
it  is  given  later.  Output  from  the  final  6360  plate 
circuit  is  taken  off  through  coax,  and  provision 
is  made  for  tuning  out  the  reactance  of  the  link, 
with  ^4. 

Con  s  tru  c  tion 

The  transmitter  is  built  on  a  flat  plate  of  sheet 
aluminum  5  by  10  inches  in  size.  This  is  screwed 
to  a  standard  aluminum  chassis  of  the  same  di- 
mensions, that  serves  as  both  case  and  shielding. 
If  more  (complete  shielding  is  required,  a  per- 
forated metal  cover  may  \n\  made  to  go  over  the 
top,  as  was  done  with  th(!  6-  and  2-meter  rigs

Adjustment 

The  power  supply  for  testing  the  transmitter 
should  deliver  at  least  ',]  amperes  at  G.3  volts, 
a.c.  or  d.c,  and  200  to  :500  volts  d.c.,  at  200  ma. 
The;  lower  voltage  is  plenty  for  the  test  work, 
though  up  to  300  may  be  used  when  everything 
is  properly  adjusted.  If  a  300-volt  supply  is  used 
for  the  testing,  the  tubes  can  be  protected  from 
excessive  drain  by  connecting  a  5000-ohm  10-watt 
resistor  in  series  with  the  power  supply  lead.  The 
power  connectors,  Ji  and  Pi,  make  provision  for 
metering  all  plate  circuits  except  those  of  the 
oscillator  and  first  tripler.  The  power  leads  to 
these  are  shown  connected  together,  to  Pin  2  of 
Ji,  but  during  testing  they  should  be  fed  se{>

arately   through   a   miUiammeter,    as   described 
below. 

Testing  will  be  easier  if  a  receiver  capable  of 
tuning  to  8  and  24  Mc.  is  available.  Connect  a 
0-50  or  0-100  miUiammeter  between  Pin  2  of 
/i  and  the  oscillator  plate-screen  circuit,  at  the 
low  side  of  the  22,000-ohm  screen-dropping  re- 
sistor, point  A  on  the  schematic.  Be  sure  that  the 
tripler  plate  and  screen  resistors  are  disconnected 
for  the  time  being,  to  prevent  this  stage  from 
drawing  current.  Appty  200  to  300  volts  d.c. 
through  Pin  2  of  Pi,  and  tune  the  plate  circuit 
of  the  oscillator  to  the  third  harmonic  of  the 
crystal  frequency.  If  you  can  listen  on  this  fre- 
quency (24.45  to  25  Mc,  depending  on  choice  of 
crystal)  a  large  increase  in  signal  strength  should 
be  noted  as  the  coil  is  tuned  through  resonance. 
A  double  check  on  frequency  with  a  calibrated 
grid-dip  or  absorption  wavemeter  is  recom- 
mended. Oscillator  plate-screen  current  will  be 
about  20  ma. 

Now  connect  the  oscillator  plate-screen  power 
lead  directly  to  Pin  2  on  Ji,  and  insert  the  meter 
in  the  lead  to  the  tripler  plate-screen  circuit, 
point  B  on  the  diagram.  Apply  voltage  and  tune 
the  tripler  plate  circuit  for  maximum  output 
at  73.35  to  75  Mc.  A  2-volt  60-ma.  pilot  lamp 
with  a  single-turn  loop  of  insulated  wire,  about 
a  half  inch  in  diameter,  may  be  coupled  to  L2 
to  serve  as  an  output  indicator.  The  6CL6  tripler 
plate-screen  current  will  be  about  the  same 
as  the  oscillator,  around  20  ma.  at  300  volts. 

Now  wire  the  power  leads  to  these  two  stages 
as  shown  in  the  tliagram.  Leave  the  300-volt  lead 
connected  to  Pin  2  of  Pi,  and  connect  a  100-ma. 
meter  between  Pins  2  and  4,  to  measure  the  6360 
tripler  plate-screen  current.  A  low-range  miUiam- 
meter, about  0-10  ma.,  should  be  connected 
between  Pin  5  and  Pin  1,  to  measure  final  grid 
current.  Tune  Co  for  maximum  indication  on  this 
meter.  With  no  plate  voltage  on  the  final  stage, 
there  should  be  at  least  3  ma.  grid  current.  Adjust 
the  spacing  between  L3  and  L4  cai'efully,  retuning 
C2  after  each  adjustment,  for  maximum  grid 
current. 

In  adjusting  the  final  stage,  we  will  ignore  the 
eventual  use  of  a  modulator,  and  connect  our 
power  supply  direct  to  the  final  stage  temporarily. 
Information  on  modulation  will  t)e  given  later. 
Solder  a  jumper  between  Pins  2  and  4  on  Ji,  so 
that  voltage  will  be  supplied  to  the  6360  tripler. 
Connect  a  temporary  jumper  between  Pin  2  and 
Pin  7,  to  feed  voltage  to  the  final  screen,  and 
connect  the  0-100  miUiammeter  between  Pins  2 
and  8,  to  measure  final  plate  current.  A  10-  or 
15-watt  light  bulb  may  be  used  as  a  temporary 
dummy  load,  coimected  to  Jo-  Apply  voltage 
and  tune  C'3  for  minimum  plate  curient,  or  for 
maximum  output  as  indicated  in  the  lamp  load. 
Adjust  (\  for  best  outjmt.  The  setting  of  (U 
and  the  degree  of  coupling  between  L5  and  L,; 
will  be  different  for  an  antenna,  however,  as  the 
lamp  is  not  a  good  load  at  this  frequency. 

If  the  stage  is  completely  stable,  maxiniuni 
output,  maximum  grid  current  and  minimum 
plate  current  should  all  occur  at  the  same  setting 


of  the  plate  tuning  capacitor,  C3.  Another  check 
for  neutralization  is  to  cut  the  drive  for  a  brief 
period  by  removing  plate  and  screen  voltage 
from  the  tripler.  Grid  current  should  drop  to 
zero  when  this  is  done.  If  it  does  not,  the  final 
stage  is  oscillating,  and  must  be  neutralized.  In 
the  original  model,  there  was  no  actual  self  oscil- 
lation, but  the  stage  was  not  completely  stable 
until  a  small  amount  of  neutralization  was  added. 
This  is  done  very  simply  with  the  6360.  The 
leads  are  so  arranged  within  the  tube  that  all 
that  is  required  for  neutralization  is  a  very 
small  capacitance  between  Pins  3  and  6,  and 
between  Pins  1  and  8.  A  stul)  of  No.  18  wire 
about  ^s  iiifh  long  is  soldered  to  Pin  6,  with  its 
opposite  end  "looking"  at  Pin  3.  A  similar  stub 
is  soldered  to  Pin  8,  with  its  free  end  adjacent 
to  Pin  1.  The  ends  can  then  be  bent  toward  or 
away  from  the  grid  pins  to  give  the  required  ca- 
pacitance. 

Putting  the  Rig  on  the  Air 

When  all  stages  have  been  adjusted  correctly, 
the  plate  voltage  may  be  increased  to  300  on 
all  stages,  if  you  want  to  run  the  maximum 
power  of  which  the  tubes  are  capable.  Current 
drains  indicated  on  the  schematic  diagram  are 
for  300-volt  operation.  Staying  at  250  volts  or 
less  allows  more  conservative  operation,  and 
ma3^  be  well  worth  while,  in  the  interest  of  longer 
life  for  the  6360s.  There  is  no  great  advantage  to 
be  gained  from  pushing  the  tubes  excessively,  as 
doubling  the  i)ower  output  will  net  less  than  one 
S  unit  improvement  in  signal  level  at  the  re- 
ceiving end. 

In  feeding  power  to  an  antenna  system  using 
coaxial  line,  it  is  merely  necessary  to  connect 
the  coax  to  the  output  fitting,  ./o,  and  adjust  the 
coupling  and  C'4  for  maximum  radiated  power. 
A  field-strength  meter  that  will  be  helpful  in 
this  was  described  in  QST  for  December,  1953, 
page  43.  If  300-ohm  Twin-Lead  or  open-wire 
line  is  used  to  feed  the  antenna,  coupling  to  the 
transmitter  is  done  with  a  coaxial  balun,  made

Director  Beams 


Improved  V.H.F.  Antenna  Performance  with  Fewer  Elements 

and  No  Reflectors 

BY  FRANK  C.  JONES,*  W6AJF 


NEARLY  all  v.h.f.  beam  antennas  use  resonant 
reflectors,  to  provide  good  forward  gain 
and  reduce  signal  pick-up  and  radiation 
from  the  rear  of  the  array.  However,  an  investi- 
gation of  several  types  of  beams  conducted  in 
the  220-Mc.  band  showed  that  it  is  possible  to 
dispense  with  reflectors  entirely.  Furthermore, 
by  modification  of  the  usual  coUinear  arrange- 
ment, a  design  was  evolved  that  used  only  half  as 
many  directors  as  one  would  expect. 

The  result  was  a  6-element  array  with  per- 
formance equivalent  to  that  of  the  usual  collinear 
arrangement  having  four  half-wave  driven  ele- 
ments, with  reflectors.  Two  of  these  can  be 
combined  into  a  12-element  beam  that  is  equal 
to  the  conventional  1 6-element  design.  Of  even 
greater  interest,  the  front-to-back  ratio  can 
actually  be  made  better  with  directors  only, 
without  the  usual  sacrifice  in  forward  gain  that 
is  entailed  in  adjusting  for  optimum  front-to- 
back  ratio. 

If  a  reflector  type  of  beam  with  four  driven 
elements  and  four  reflectors  is  adjusted  for  good 
front-to-back,  over  12  db.,  the  forward  gain  is 
reduced  at  least  1  db. ;  if  it  is  adjusted  for  best 
forward  gain,  the  front^to-back  ratio  is  liable  to 
be  considerably  less  than  10  db.  On  the  other 
hand,  a  director-t3'i)e  beam  of  four  driven  ele- 
ments and  two  directors  can  be  adjusted  to  pro- 
vide more  than  15  db.  front^to-back  ratio,  with- 
out sacrificing  more  than  }  2  db.  forward  gain. 

An  example  is  a  12-element  2-meter  director 
beam  at  W6AJF  that  has  a  front-to-back  of  17 
db.  and  a  forward  gain  of  approximatel}-  13  db. 
A  conventional  16-element  collinear  array  can 
be  adjusted  for  about  this  same  gain,  but  the 
back  lobe  becomes  objectionable,  so  the  usual 
dimensions  provide  about  12  db.,  with  a  front- 
to-back  ratio  of  10  to  12  db. 

Something  for  Nothing? 

This  better  front-to-back  and  more  forward 
gain  with  less  elements  in  the  arraj^  looks  like

A  6-element  2-meter  array  that  outperforms 
the  conventional  8-element  job.  It  uses  short- 
ened driven  elements  in  pairs,  with  a  single 
director  for  each  pair.  W6AJF's  daughter  tries 
it  on  for  size. 


a  claina  of  something  for  nothing,  but  such  is  not 
the  case.  There  is  a  price.  The  director  beam 
must  be  made  with  close  director  spacing  to 
obtain  good  rejection  off  the  back  without  sacri- 
ficing forward  gain.  This  means  low  radiation 
resistance  at  the  current  points,  less  bandwidth 
and  increased  difficulty  in  matching  the  beams  to 
standard  transmission  lines. 

The  bandwidth  limitation  is  not  serious  at 
144  or  220  Mc,  as  the  director-type  array  has 
a  bandwidth  of  about  5  Mc.  in  these  bands,  com- 
pared to  8  or  12  Mc.  for  the  conventional  col- 
linear designs.  The  bandwidth  of  the  director 
beam  for  50  Mc.  would  be  only  about  2  Mc,  and 
perhaps  12  Mc.  or  so  at  420  Mc.  These  values 
are  too  low  for  full  band  coverage,  so  the  design 
would  have  to  be  for  the  parts  of  these  bands 
which  are  of  primary  interest.  The  bandwidth  is 
ample  for  the  144^  and  220-Mc.  bands  with 
design  centers  at  146  and  222.5  Mc. 

A  close-spaced  director,  whether  used  with 
one  or  two  driven  elements,  detunes  the  driven 
elements  and  all  elements  have  to  be  made  a 
little  longer  than  expected.  For  example,  a  direc- 
tor in  this  design  is  39  inches  long  for  the  2-meter 
band,  and  253  2  inches  long  for  the  220-Mc.  band. 
Fortunately,  the  driven  elements  can  be  tuned 
to  resonance  by  a  short  stub,  and  the  main  trans- 
mission line  tapped  across  this  stub  at  the  proper 
point  for  impedance  matching.  There  is,  there- 
fore, no  critical  length  for  the  driven  elements  in 


April  1955 


such  a  system.  Where  two  such  3-elenieiit  bays 
are  used  a  single  stub  can  l)o  used  to  resonate  the 
entire  system. 

In  curtain  array's  or  with  Yagis  spaced  a  half 
wavelength  apart,  there  is  a  bucking  action  of 
directors  of  one  bay  upon  those  of  the  other.  Re- 
flectors spaced  a  half  wave  apart  aid  slightly  in 
the  forward  gain  of  a  beam,  especially  in  a  4- 
or  8-element  design.  Directors,  on  the  other 
hand,  tend  to  cancel  each  other's  gain  when  used 
at  half-wave  spacings  between  bays.  It  was 
found  that  ^s"  ^  ^-wavelength  spacing  mini- 
mized this  efTect  when  two  directors  were  used, 
but  ^  8  wavelength  was  not  sufficient  spacing  for 
two  baj's  having  four  directors  each  in  a  broad- 
side beam,  in  tests  at  WGAJF.  A  2-meter  ver- 
ticall>'-polarized  beam  of  this  type  had  a  very 
sharp  front  lobe,  with  large  side  lobes  and  less 
than  expected  forward  gain.  When  the  two  6- 
element  Yagis  that  made  up  this  array  were  cut 
apart  and  stacked  vertically,  a  considerable  im- 
provement in  forward  gain  resulted,  and  there 
was  a  marked  reduction  in  the  side  lobes. 

One  Director  for  Two  Driven  Elements 

In  stacking  the  3-element  design  shown  in 
Fig.  1  the  director  current  maximum  points  are 
spaced  about  a  wavelength  apart,  so  there  is  no

appreciable  cancellation.  A  broadside  spacing 
(in  vertical  arrays)  of  about  %  wavelength  (60 
inches  at  2  meters)  seems  a  good  compromise 
value  as  regards  amplitude  of  side  and  back 
lobes. 

The  idea  of  using  a  single  director  with  two 
driven  elements,  as  shown  in  Fig.  1,  was  devel- 
oped by  Ralph  Bykerk,  W6YSD.  Tests  on  220 
Mc.  proved  that  actually  more  gain  could  be 
obtained  with  one  director  than  with  tw^o,  when 
using  two  half-wave  driven  elements,  because 
of  the  close  end-to-end  spacing  of  directors  when 
two  are  used.  Gain  measurements  at  145  and 
221  Mc.  showed  7  db.  gain  with  this  simple  3- 
element  beam,  and  front-to-back  ratios  as  high 
as  30  db.  Six-element  beams  of  the  type  shown 
in  Fig.  2  gave  maximum  values  of  11  db.  forward 
gain,  with  an  average  of  10  db.  over  the  whole 
144- and  220-Mc.  bands. 

The  two  driven  elements  were  originally  cut 
to  38  inch(!S  (for  2  meters)  but  a  reduction  of  the 
radiating  i)ortions  to  30  inches  did  not  reduce  the 
forward  gain  because  the  two  current  points  were 


moved  down  behind  the  director.  Apparently, 
the  gain  of  this  ari'angement  compensated  for 
the  reduction  in  field  strength,  from  the  diiven 
elements  alone,  when  their  current  maximum 
points  are  brought  to  less  than  a  half  wave  apart.

Fig.  2  —  Two  3-element  arrays  for  144  Mc.  may  be 
connected  about  %  wavelength  apart  to  make  a  ft- 
element  beam  having  a  gain  of  10  db.  or  better. 

The  shorter  driven  elements  require  a  longer 
tuning  stub  for  the  whole  beam. 

One  6-element  array,  shown  in  the  photo- 
graph, uses  300-ohm  Twin-Lead  for  all  portions 
of  the  feed  system.  The  driven  elements  are  half- 
inch  aluminum  tubing  31  inches  long,  mounted 
on  J 1  6-inch  canvas  bakelite  insulators.  The  latter 
have  short  aluminum  sleeves  over  them  where 
they  pierce  the  1-inch  mounting  booms,  leaving 
an  insulation  gap  of  about  3  2  i'K'h  on  each  side 
to  the  two  driven  elements.  The  main  boom  is 
1-inch  aluminum  tubing  5  feet  long,  so  the  dis- 
tance betW'Cen  the  elements  is  58  inches.  The 
short  booms  on  which  the  directoi-s  are  mounted 
are  7  inches  long,  to  allow  a  spacing  from  the 
driven  elements  of  6  inches.  The  directors,  being 
mounted  at  their  electrical  centers,  are  not 
insulated. 

The  phasing  line  of  300-ohm  Twin-Lead  is  not 
transposed.  For  this  particular  antenna  the 
tuning  stub  was  32  inches  long,  with  the  300-ohm 
feeder  tapped  up  3  inches  from  the  shorted  end. 
For  test  pinposes,  a  balun  was  used  at  the  feed 
point  to  step  this  impedance  down  to  75  ohms 
for  connection  to  75-ohm  coaxial  transmission 
line  to  the  ti-ansmitter.  Extreme  care  must  be 
taken  to  maintain  exactly  equal  line  impedances 
and  power  input  to  the  lines  when  comparing  a 
beam  with  a  standard  dipole  antenna  for  relative 
forward  gain  figures.  These  conditions  are  most 
readily  met  when  coaxial  line  is  used. 

Another  2-meter  6-element  beam  was  made 
with  open-wire  feeders.  In  this  case  the  directors 
were  39  inches  long,  of  3^-inch  diameter,  mounted 
6  inches  in  front  of  the  driven  elements,  as  before. 
The  latter  were  30  inches  long,  of  the  same 
material.  End  insulators  were  of  fiber  bakelite 
tubing,  3^-inch  o.d.  and  3i-inch  i.d.,  to  take  the 
driven  elements.  This  particular  model  had  54- 
inch  spacing  broadside,  instead  of  the  preferred 
value  of  about  60  inches.  The  tuning  stub  of 
ojjen-wire  lin(>  turned  out  to  be  43  inches  long, 
with  the  main  tiansmission  lint;  tapped  at  6  inches 
from  the  shorted  end.  The  length  of  the  stub 
should   lie  adjusted  for  resonance  at  the  band

inches  deep,  11  inches  wide,  and  12  inches 
high  (Bud  C-881).  Two  shelves,  5  by  8  inches, 
were  cut  from  sheet  aluminum.  After  bending 
one  edge  to  permit  bolting  to  the  panel,  each 
shelf  ended  up  4}i  b\'  8  inches.  The  whole 
rig  can  be  easily  removed  by  disconnecting  the 
batteries  and  unscrewing  the  front  panel. 

The  Receiver 

The  receiver  is  a  simple  regenerative  type 
with  a  single  stage  of  audio,  but  it  works  well. 
\\'ith  a  good  antenna,  strong  signals  pound  in 
and  you  sometimes  use  the  volume  control 
which  normally  is  wide  open.  Selectivity,  of 
course,  is  not  the  best  but  good  bandspread 
helps  a  lot. 

While  one  coil  to  cover  both  40  and  80  can  be 
wound,  two  coils  are  recommended  for  maximum

tom and  the  transmitter  at  the 
top.  The  dial  to  the  left  is  for  the

and  switch,  transmitter  tuning

toggle  switches  are  in  the  battery 
circuits.  The  holes  at  the  right 
and  on  top  are  for  ventilation.

Microphonics  are  quite  bad  so  try  not  to  hit 
the  receiver  when  operating. 

It  is  a  good  idea  to  calibrate  the  receiver 
so  you  can  locate  exact  frequencies  out  in  the 
field.  Note  the  dial  settings  of  "main  tuning" 
and  "bandspread"  on  a  card  and  keep  it  in  the 
logbook. 

To  lengthen  battery  life,  turn  off  filament  and 
plate  voltages  on  receiver  and  transmitter  at 
every  opportunity  (turn  off  receiver  when 
sending,  transmitter  when  receiving).  The  tubes 
heat  almost  instantly. 

Label  all  battery  leads  with  small  pieces  of 
paper  fastened  to  the  leads  with  Scotch  Tape. 

The  Transmitter 

The  transmitter  circuit  is  almost  identical 
to  that  of  the  "Last  Ditcher,"  ^  and  uses  a 
1J6G  twin  triode  in  a  push-pull  crj'stal  oscillator. 
Properh'  loaded,  the  tube  draws  about  20  ma. 
at  135  volts,  or  2.7  watts.  The  note  will  be 
pure  and  sharp  if  the  crj-stal  is  a  good  one.  An 
inactive  crj^stal  will  cause  a  chirpy  note.  Separate 
crystals  are  required  for  each  band,  of  course. 

7?i  drops  the  3-volt  supply  to  2  volts  for  the 
IJOG.  It  can  be  made  up  from  two  10-ohm  and 
one  20-ohm  1-watt  resistors  in  parallel.  However, 
a  variable  rheostat  is  preferable  so  that  compensa- 
tion maj^  be  made  as  the  batter}-  voltage  drops 
off.  Plate  voltage  is  not  critical,  and  a  maximum 
of  180  volts  may  be  used;  the  tube  will  oscillate 
with  only  223/^  volts.  For  greater  plate-battery 
life,  two  identical  batteries  can  be  added  in 
parallel,  if  desired. 

At  the  top  of  the  panel,  to  the  left,  a  J^-inch 
hole  permits  the  2.5-volt  0.06-amp.  tuning 
bulb  to  peek  ,^4  inch  through  the  panel.  This 
makes  it  easy  to  take  out  blown  bulbs.  When 
the   batteries   are   new,   the   2.5-volt  bulb   may 


26 


QST  for 


burn  out,  so  you  will  want  to  have  a  7-8-volt 
bulb  handy. 

Next  to  the  bulb  is  the  3-position  switrh,  Si. 
When  the  switch  is  turned  to  the  left  to  receive, 
tlie  antenna  is  connected  to  the  receiver.  When 
the  switch  is  in  the  middle  (transmit)  the  link, 
Lo,  is  connected  to  the  antenna.  With  the  switch 
in  the  right-hand  position  (test)  and  the  antenna 
terminals  shorted,  the  tuning  bulb  is  placed 
across  the  link  and  will  light  brighth'  when  the 
transmitter  is  oscillating.  With  the  short  re- 
moved from  the  antenna  terminals  and  the 
switch  still  in  the  test  position,  the  bulb  is  in 
series  with  one  leg  of  the  feeders.  Tune  the  con- 
denser for  ma.ximum  radiation  (brightest  bulb). 
Now  that  the  antenna  is  taking  the  load,  switch 
to  transmit,  which  removes  the  bulb  from  the 
circuit  and  you're  in  business. 

The  Antenna 

The  antenna  is  the  key  to  success  with  low 
power  (and  with  high  power,  too).  So  far,  three 
antennas  have  been  used  with  "Tiny  Tim": 

1)  A  4-section  automobile  radio  antenna 
(W'ard  SC-8)  is  mounted  on  the  side  of  the 
cabinet  (the  whip  can  be  pulled  out  easily,  the 
mountings  removed  and  the  holes  plugged  with 
bezels,  when  desired).  This  antenna  is  base- 
loaded,  using  a  coil  2}^  inches  in  diameter  with 
about  45  turns  of  No.  14  wire,  and  is  worked 
against  a  ground  consisting  of  four  wires,  each 
10  feet  long,  joined  like  the  sj)okes  of  a  wheel, 
at  90  degrees  to  each  other,  pegged  to  the  ground. 
The  ground  connection  is  to  the  junction  of  these 
radials.  Better  counterpoises  are  described  in  the 
ARRL  Handbook,  but  this  one  works  well.  The 
advantage  of  this  antenna  is  that  it  is  easy  to 
disconnect  and  pack  up  in  a  box.  It  is  not  very 
efficient  for  receiving  or  transmitting  but  it 
works.  A  center-loaded  or  top-loaded  whip  would 
increase  efficiency  but  would  not  telescope  into  a 
short  length  like  this  does. 


OSC. 


The  rear  panel  of  the  cabinet  is  rut  and  hinfrod  to 
liermit  eas>  baniJclianging.  Spare  coils.  ke> .  it>  stals, 
as  well  as  log  and  pencil,  are  stowed  in  racks  inside 
the  door.  The  three  transmitter  batteries  are  at  the 
upper  right,  and  the  receiver  batteries  are  below.  Aluin- 
inum  straps  hold  the  batteries  securely  in  place. 

2)  The  stainless-steel  rigging  on  our  ID-foot 
sailboat  was  connected  to  one  side  of  the  link 
and  worked  against  a  4j^-foot  bronze  center- 
board  in  the  water.  The  loading  coil  and  a  series 
condenser  were  ready  but  not  needed.  This 
antenna,  again,  is  not  verj^  efficient,  but  was 
the  best  possible  under  the  often  hectic  condi- 
tions and  limited  space  in  a  small  sailboat! 

3)  The  best  antenna,  by  far,  is  one  136  feet 
long,  as  high  as  possible  and  in  the  clear.  A 
good  portable  antenna  can  be  made  from  solid 
copper  trolling  line,  with  nj-lon  fishing  line  as 
combination  insulator-halyards.  A  72-ohm  re- 
ceiving-type line  can  be  used  as  the  feeder.  This 
antenna  (-an  be  rolled  up  on  a  light  wooden  reel, 
and  works  well. 

Any  antenna  and  antenna  loading  method  can 
be  used  with  "Tiny  Tim"  but  the  higher  the 
antenna,  the  better  the  results.  The  rig  could

Emergency  Power  Distribution 

Preparing  for  Field  Day  and  Emergencies 
BY  GERALD  T.  WHITE,*  WIWUJ 


IN  the  rush  oF  preparing  for  Field  Days  — 
and  especially  emergencies  —  little  thought 
is  given  to  a.c.  power  distribution  beyond 
getting  a  generator  and  plugging  in.  The  as- 
sociated twisted  bare  connections,  multiple  cube 
taps,  absence  of  fuses,  and  so  on,  not  only  make 
for  lack  of  reliability  but  also  create  a  personal 
hazard  for  everybody  coming  near  the  site. 

Invariably,  not  enough  electrical  fittings  are 
brought  along,  so  off  come  more  plugs  and 
more  twisted  connections  are  made,  only  to 
come  apart  in  the  middle  of  a  QSO.  With  no 
fuses  in  the  circuit,  especially  in  multiple- 
transmitter  installations,  one  short-circuit  puts 
everybody  off  the  air.  If  the  line  voltage  is  in 
doubt,  there  might  be  available  a  multitester  of 
questionable  accuracy  (probably  not  having 
been  used  to  read  115  volts  a.c.  since  last  Field 
Da3').  After  poking  the  prods  in  the  nearest 
spare  outlet,  they  are  usually  left  there  to 
"monitor"  the  voltage.  Only  with  luck  will  they 
fail  to  fall  together  and  short. 

After  reviewing  the  situation  it  was  decided 
to  plan  the  a.c.  power  distribution  system  for 
the  June,  1954,  Field  Day.  The  problem  divided 
itself  into  three  major  categories:  (1)  generator, 
(2)  feeder  layout,  and  (3)  feeder  termination. 

Generator 

The  first  problem,  the  generator,  requires 
careful  consideration.  Both  single-  and  three- 
jihase  generators  are  genei'ally  available.  The 
most  desirable  generator  is  one  with  single- 
phase  output,  especially  220  volts  center-tapped.

ces.sorics  iiicntioiK'd  in  llic  Icxt  and  serves  as  a  useful 
piece  of  slallon  and  shop  e<pii|inietit  in  the  interim  be- 
tween Field  Days. 


However,  many  c.d.  groups  may  fall  heir  to 
military-surplus  3-phase  1 10-volt  units,  and  these 
can  be  used  if  a  few  precautions  are  observed. 

Maximum  output  should  not  be  drawn  from 
either  a  22{)-volt  single-phas:;  center-tapped  gen- 
erator or  a  1 10-volt  3-phase  generator  unless 
each  leg  is  equally  loaded.  If  multiple  transmitters 
are  placed  on  separate  legs,  the  line-voltage 
fluctuations  caused  by  transmitter  keying  are 
gi'eatly  reduced. 

The  engine  governor  should  be  adjusted  to 
not  less  than  55  c.p.s.  line  frequency  under  full 
load.  If  it  is  set  for  60  c.p.s.  at  no  load,  the 
frequency  may  drop  to  well  below  50  c.p.s. 
under  load  and  damage  to  equipment  may 
result.  The  smaller  generators  are  parti(;ularly 
susceptible  to  this  fault.  A  60-cycle  electric 
clock  can  be  used  to  check  the  line  frecjuency 
if  a  regular  frequency  meter  is  not  available.  If 
the  clock  second  hand  covers  much  less  than  50 
seconds  in  a  minute,  look  out!  Almost  all  ham 
electronic  equipment  will  operate  properly  above 
60  c.p.s.;  however,  60-cycle  generators  should 
not  be  pushed  to  much  over  75  c.p.s.  or  the 
engine  bearings  are  likely  to  be  damaged  under 
the  prolonged  excessive  speed. 

Power  Distribution 

The  second  problem,  feeder  layout,  should 
also  be  given  careful  thought.  No  fuses,  switches, 
or  ammeters  should  be  placed  in  any  wire  that 
is  common  to  two  or  more  branch  circuits.  One 
side  of  each  circuit  should  be  grounded,  if  only 
by  a  short  rod  in  moist  earth,  to  help  prevent 
shocks  and  to  reduce  the  explosion  hazard  when 
gassing  and  servicing  the  generator.  (People 
will  attempt  to  service  them  while  they  are 
running!) 

In  a  3-phase  Y-connected  system,  the  common 
connection  should  be  grounded.  In  a  3-phase 
delta  fully-loaded  system,  one  phase  must  have 
both  sides  above  ground,  so  pick  one  fall  guy 
and  let  him  plan  accordingly.  However,  if  only 
5  k.v.a.  is  required  from  a  7.5  k.v.a.  generator, 
then  there  is  no  problem:  just  ignore  one  phase 
and  use  the  junction  of  the  other  two  phases  as 
common  and  ground.  It  should  be  determined 
ahead  of  time  which  phase  is  regulated,  and  this 
phase  should  be  used  for  the  average  (or  heaviest) 
load  and  the  line  voltage  adjusted  accordingly 
to  prevent  excessively  low  voltage  or  (Hiuipment 
burnouts. 

A  fuse  should  l)e  inserted  in  the  "hot"  wire 
of  each  feeder  pair  leaving  the  generator.  These 
fuses  should  be  only  a  little  larger  than  each 
station  needs,  and  the  total  fused  current  should 
not  exceed  the  generator  capacity.  Each  trans- 


28 


QST  for 


mitter  site  should  have  a  separate  feeder  direct 
to  the  generator  to  reduce  voltage  drop,  varia- 
tions, outage,  etc. 

All  transmitter,  receivci-,  and  othci-  chassis  at 
each  site  should  be  wired  together  and  grounded. 
This  will  avoid  r.f.  burns  and  prevent  the  annoy- 
ing tingle  from  the  a.c.  line  by-passes  found  in 
most  commercial  equipment. 

A  source  of  adequate  a.c.  feeder  cable  is 
always  a  problem.  Coaxial  cable  that  is  too 
old  to  be  of  further  value  in  r.f.  service  makes 
excellent  feeder  cal)le.  For  high  currents,  connect 
the  inner  and  outer  conductors  together  and  run 
two  cables  for  tlu^  two  conductors.' 

Terminal  Facilities 

The  last,  but  equally  important,  problem  is 
feeder  termination.  The  receptacle  panel  should

them  direelly  applicable  to  your  own

anticipation  that  adequate  cable  would  not 
always  be  available.  One  bus,  with  three  duplex 
receptacles,  is  designed  for  a  maximum  of  30 
amperes  for  transmitters,  lights,  and  accessories. 
Under  these  circumstances,  two  separate  pairs 
of  feeders  would  be  brought  to  the  panel  from 
the  generator,  thus  providing  better  regulation 
for  voltage-sensitive  eciuipment.  The  two  busses 
could  be  paralleled  when  satisfactory  feeders  are 
available.  If  fuses  are  provided  at  the  generator 
end  of  the  feeder,  it  will  be  desiraV)le  to  insert 
smaller  fuses  at  the  receptacle  panel  than  at  the 
generator,  to  prevent  blowing  two  fuses  when  a 
short  circuit  occurs. 

It  is  not  necessary  to  use  expensive  meters. 
There  is  at  least  one  type  of  inexpensive  meter 
on  the  market  that  is  well-damped  and  is  quite 
satisfactory. 

The  '"quintet "-type  receptacle,  providing  space 
for  five  flat  or  three  round  a.c.  plugs,  is  far 
better  and  safer  than  using  duplex  receptacles 
with  cube  taps. 

Besides  its  Field  Day  and  emergency  applica- 
tions, the  receptacle  panel  will  be  a  most  useful 
addition  to  any  home  workbench  since  it  has 
adequate  outlets  and  meters  to  service  modern 
electronic  eciuipment  properly. 

It  is  the  author's  belief  that  it  is  always  better 
to  do  as  much  as  possil)le  in  the  home  workshop 
l)efore  Field  Day  or  an  emergency  and  thereby 
avoid  frustrating  work  under  difficult  conditions 
in  the  field. 


contain  at  least  eight  outlets,  protected  by  a  fuse 
and  monitored  by  a  panel-type  a.c.  voltmeter, 
and  a  small  night  light.  An  a.c.  ammeter  is  also 
desirable  to  help  ecjualize  loads  on  the  generator. 
A  frecjuency  meter  or  an  electric  clock  ma\'  be 
mounted  on  the  i^anel  so  it  will  be  available. 

It  will  be  noted  in  Fig.  1  that  the  night  light 
is  connected  ahead  of  the  fuses  while  the  volt- 
meter is  connected  after  the  fuses  and  ammeters. 
This  provides  for  instantaneous  indication  as  to 
whether  the  local  fuse  blew,  the  ammeter  opened 
up,  or  whether  the  main  power  failed. 

Fig.    1    also    shows    two   separate    busses,    in 

1  Feeder  voltage  drop  can  be  estimated  quickly  by  re- 
membering that  there  will  be  one  volt  drop  per  ampere  per 
100  feet  in  a  conductor  having  an  area  of  1000  circular  mils. 
The  drop  is  directly  iiroportional  to  current  and  length,  and 
inversely  proportional  to  circular  mil  area.  The  center  con- 
ductor of  RG-8/U  (5670  cm.)  would  have  a  drop  of  1  volt 
per  hundred  feet  at  a  current  of  5.67  amp.  In  a  go-and-return 
circuit  (two  wires)  the  drop  should  be  figured  on  the  total 
wire  lengtli,  of  course.  —  Ed.

Ferroxcube  Cores  and  a  High-Selectivity 

I.F.  Amplifier 

Design  Notes  and  Suggestions  for  Improved  Receiver  Selectivity 
BY  J.  S.  BELROSE,*  EX-VE7QH,  EX-VE3BLW 


•  If  you  follow  rereiver  design  and  im- 
provements, you  will  be  interested  in 
this  aeeount  of  a  new  inductor-core  ma- 
terial that  can  be  easily  used  by  the 
amateur.  Several  possible  circuits  are 
described,  as  well  as  the  practical  design 
data  for  a  high-selectivity  20-kc.  i.f. 
amplifier. 


WITHIN  the  last  few  years  there  has  been 
considerable  interest  in  the  development 
of  the  ideal  communications  receiver.  The 
progress  made  toward  this  goal  can  be  readily 
seen  if  one  traces  the  development  of  commer- 
cial communications  receivers  during  the  past 
nine  years. 

The  trend  in  receiver  design  has  advanced  from 
the  simple  but  effective  regenerative  i.f.  amplifier 
(single-signal  superhets  so  popular  in  the  prewar 
ARRL  Handbooks)  to  the  complicated  triple- 
tuned  and  quadruple-tuned  low-frequency  i.f. 
amplifier  of  the  present  day.  The  mechanical 
filter  (or  magnetostriction  filter)  has  recently 
been  developed,  and  it  provides  an  opportunity  to 
obtain  a  maximum  skirt  selectivity  and  quite 
narrow  bandwidths  with  a  minimum  number  of 
stages.  And,  of  course,  we  still  have  our  old 
stand-by,  the  crystal  filter.  However,  very  high-Q 
selective  LC  filters  can  be  designed  that  will  pro- 
vide a  maximum  receiver  selectivity  and  which 
can  be  easily  constructed  by  the  amateur  radio 
designer. 

Several  excellent  articles  have  appeared  in 
QST  on  selective  amplifiers. ^•'■^'^  The  purpose  of 
this  article  is  to  collect  together  some  practical 
data,  which  the  author  has  accumulated  during 
the  last  few  years  of  experimental  receiver  design, 
and  to  present  these  data  in  the  form  of  notes  for 
the  amateur  who  prefers  to  build  his  own  re- 
ceiver. And,  together  with  some  simple  circuit 
theory,  an  amplifier  will  be  designed  that  has  an 
extremely  narrow  bandwidth  and  excellent  skirt 
selectivity.  In  conjunction  with  a  good  r.f.  tuner, 
this  amplifier  will  outperform  any  receiver  which 
is  at  present  commercially  available.  The  recent 
advances  made  in  the  development  of  low-loss 
ferromagnetic-cored  materials  for  high-Q  induc-

tors  have  made  coil  design  and  construction  a 
pleasure,  and  they  inspired  the  author  to  write 
this  article.  Since  the  heart  of  the  amplifier  is  the 
highly-selective  filter,  it  is  necessary  that  a  good 
portion  of  this  article  should  be  devoted  to  a 
general  introduction  to  the  use  of  these  core 
materials. 

General  Considerations 

In  the  design  of  a  communications  receiver  for 
radiotelegraphy,  it  is  the  author's  opinion  that  a 
good  receiver  should  be  a  double-conversion 
superhet  and  that  the  second  i.f.  should  be  as  low 
as  possible,  in  order  to  achieve  the  required  selec- 
tivity and  stability.  Low-frequency  amplifiers  can 
readily  be  designed  that  have  noise  figures  near  to 
unity  but,  in  any  case,  the  over-all  noise  figure  of 
the  receiver  is  decided  in  the  first  stages,  so  this 
factor  will  not  be  considered  here.  Two  stages  of 
455-kc.  amplification  should  be  provided  to  avoid 
image  problems  with  the  low  second  i.f.  The 
455-kc.  signal  should  be  fed  to  the  second  mixer 
at  low  level  by  means  of  a  cathode  follower.  The 
signal-handling  capacity  of  the  stages  before  the 
narrow-bandwidth  stages  should  have  sufficient 
dynamic  range  to  avoid  cross-modulation  distor- 
tion by  strong  adjacent-channel  signals. 

Operators  not  used  to  copying  signals  received 
through  a  very  narrow  bandwidth  will  find  that 
this  new  experience  requires  some  learning.  The 
familiar  ring  of  a  keyed  signal,  so  characteristic  of 
a  very  selective  crystal  filter,  is  considerably  re- 
duced by  the  use  of  very  selective  bandpass 
coupled  circuits.  Hence,  narrower  bandwidtns, 
for  the  same  degree  of  ring,  can  be  used.  These 
circuits  are  in  general  designed  to  produce  an 
optimum  flat-top  amplitude  response.  For  sig- 
naling speeds  of  20  w.p.m.  and  less,  the  keyed 
signal  sounds  clear  and  with  little  ring  in  a  30- 
cycle  bandwidth,  except  under  conditions  of  great 
interference  of  an  impulse  nature  as,  for  example, 
local  thunderstorm  conditions.  As  the  bandwidth 
is  reduced  below  20  cycles,  the  Morse  characters 
start  to  run  together  and  the  information  capac- 
ity of  the  channel  approaches  zero,  as  the  band- 
width approaches  zero.  (The  power  required  to 
transmit  reliably  a  given  rate  of  information 
approaches  infinity.) 

In  the  circuit  design  to  follow,  an  amplifier 
bandwidth  of  100  cycles  is  chosen  because  this 
bandwidth  is  easily  obtained  with  presently- 
available  circuit  components.  Additional  narrow- 
band audio-frequency  filters  can  be  used  if  neces- 
sary after  the  signal  is  tuned  in.  The  over-all  cir- 
cuit stability  (from  transmitter  to  receiver)  re-

without  affecting  the  Q.  The  effective 
inductance  is  slightly  increased  by 
grounding  the  core,  since  the  distributed 
capacity  effects  are  changed.  However, 
this  is  only  of  the  order  of  a  few  nfii.  The 
upjjer  frequency  limit  for  Ferroxcube 
tuned  inductors  is  about  500  kc.

Ferroxcube  Pot  Cores 

If  an  ail-wound  coil  is  placed  in  a  medium  of 
permeability  ju  times  that  of  air,  the  s!»lf-induct- 
ance  L  will  also  be  increased  yu  times.  Since  the 
copper  losses  remain  constant,  the  Q  of  the  in- 
ductor will  be  increased.  The  resultant  increase  of 
the  qualitA'  factor  will  depend  on  the  additional 
losses  introduced  into  the  coil  by  the  core.  These 
losses  may  comprise  eddy-current  losses,  hys- 
teresis losses,  and  residual  core  losses.  Recently, 
great  advances  have  been  made  by  manufac- 
turers in  producing  ferromagnetic  materials 
which  introduce  very  small  losses.  Ferroxcube 
III  is  a  low-loss  manganese-zinc  ferrite  with 
a  cubic  crystal  structure.  The  metal  oxides  are 
extruded  in  the  form  of  a  plastic  mass  and  fired  at 
a  high  temperature;  the  result  is  a  material  of 
extremely  high  resistivity  and  having  mechanical 
properties  which  resemble  porcelain.  This  mate- 
rial has  many  uses  and  is  formed  into  quite  a 
variety  of  component  shapes.  The  "pot  core"  is  a 
specially-designed  form  developed  for  very 
high-Q  coils  as  used  in  bandpass  filters  in  carrier 
telephony  and  i.f.  coils  in  radio  engineering.  As 
shown  in  Fig.  1,  the  pot  core^  consists  of  a  ring, 
two  disks,  and  a  slug.  The  slug  is  slightly  shorter 
tlran  the  ring,  leaving  an  air  gap  in  the  otherwise 
closed  magnetic  circuit.  The  copper  windings  are 
wound  on  a  small  plastic  bobbin.  Since  the  turns 
are  entirely  surrounded  by  a  material  of  high 
permeability,  excellent  shielding  is  provided,  and 
coils  can  be  placed  cjuite  close  together  without 
causing  undesired  coupling.  The  pot-core  assem- 
bly can  be  bolted  directlv  to  the  metal  chassis 


sary  in  order  to  insure  maximum  stabil- 
ity for  the  inductance.  With  Ferroxcube,  the 
permeability  decreases  (i.e.,  the  inductance 
decreases)  as  a  result  of  d.c.  flowing  through 
the  windings  and  causing  premagnetization 
of  the  core  material.  Another  factor  to  con- 
sider is  the  low  saturation  properties  of  Ferrox- 
cube. Therefore,  if  the  sharply-tuned  filter  coil  is 
included  directly  in  the  anode  circuit  of  the  out- 
put valves  of  the  amplifier,  where  the  anode  cur- 
rent is  likely  to  change  with  the  signal  voltage, 
the  effect  is  to  detune  the  filter  and  increase  the 
bandwidth.  The  simplest  method  of  reducing 
these  effects  is  to  tap  the  plate  quite  a  way  down 
on  the  inductor,  so  that  the  d.c.  current  flows 
through  only  a  few  turns  of  the  coil.  This  results 
in  additional  advantages,  since  it  reduces  loading 
of  the  tuned  circuit  by  the  plate  resistance  of  the 
valve,  and  provides  a  convenient  means  of  reduc- 
ing the  stage  gain.  (The  stage  gain  can  become 
rather  too  high  as  a  result  of  the  large  inductance 
values  needed  to  tune  to  low  frequencies  with 
convenient  sizes  of  tuning  capacitors.) 

The  other  important  consideration  for  a  coil 
wound  on  a  magnetic  core  is  the  temperature 
coefficient  of  the  core  material.  Because  of  the 
low  Curie  point  (the  temperature  at  which  the 
permeability  becomes  practically  unity)  of  Fer- 
roxcube materials,  the  permeability  of  the  mate- 
rial is  ciuite  temperature-sensitive.  Since  the  in- 
ductance varies  directly  with  the  permeability, 
its  temperature  coefficient  will  be  identical  with 
that  of  the  core.  This  temperature  coefficient  can 
be  inadmissably  high  for  coils  used  in  narrow- 
band sharply-tuned  filters.  The  influence  of  the 
core   material  on   the  inductance  must   be  de-

creased,  and  this  is  achieved  liy  providing  an  air 
gap.  In  general,  there  is  an  optimum  air-gap  size 
for  a  given  Q.  In  some  cases,  especially  at  low 
frequencies,  it  is  desirable  to  choose  an  air  gap 
larger  than  optimum  for  a  given  Q,  in  order  to 
increase  the  stability  of  the  coil.  A  larger  air  gap 
also  reduces  premagnetization  effects.  Therefore, 
the  largest  air  gap  for  the  given  Q  should  always 
be  used.  As  a  general  I'ule,  the  higher  the  fre- 
quency the  greater  the  optimum  size  of  the  gap. 
For  gaps  larger  than  0.5  mm.  the  core  should  be 
symmetrically  located,  leaving  half  the  total  tap 
at  each  end. 

For  frequencies  less  than  about  30  kc.  the  best 
Q  is  obtained  by  winding  the  coil  with  solid 
enamel-covered  wire  (not  silk-covered),  with  the

wire  size  chosen  to  fill  the  available  winding  space 
for  the  particular  value  of  inductance  required. 
For  frequencies  above  30  kc,  and  most  certainly 
for  frequencies  between  100  and  500  kc,  the  best 
Q  is  obtained  by  using  litz  wire.  The  number  of 
turns  required  depends  on  the  length  of  the  air 
gap,  since  the  effective  permeability  is  a  function 
of  the  air-gap  size.  For  a  given  pot  core  and  a 
given  gap  size,

The  factor  oc  is  quoted  by  the  material  manu- 
facturer, and  inductors  wound  with  the  number 
of  turns  specified  are  generally  within  a  few  per 
cent  of  that  required.

selectivity,  and  off-channel  response.  The  stage 
gain  should  be  kept  low,  to  avoid  trouble  with 
oscillations  caused  by  the  difficulty  of  decoupling 
the  stages  at  low  i.f.  frequencies.  Single-tuned 
circuits  are  not  recommended  for  use  in  the  i.f. 
amplifier  because  they  give  a  comparatively  nar- 
row passband  and  poor  attenuation  outside  the 
passband  (a  crystal  is  a  vei-\'  high-Q  simple  cir- 
cuit). Capacitance  or  inductance  coupling  be- 
tween two  tuned  circuits  may  be  used  to  give  a. 
bandpass  selectivity  curve  with  good  attenuation 
rutside  the  passband.  The  coupling  impedance 
may  be  in  shunt  connection,  the  so-called  com- 
mon couj^ling,  or  it  may  be  in  series,  the  so-called 
top-end  coupling.  Four  common  types  are  illus- 
trated in  Fig.  2. 

All  of  the  methods  of  coupling 
shown  in  Fig.  2  give  somewhat  simi- 
lar selectivity  response  curves  near 
resonance  (for  near-to-critical  cou- 
pling). The  common  inductance 
type.  Fig.  2A,  is  superior  for  cou- 
pling that  is  slightly  greater  than 
critical,  since  both  peak  frequencies 
(of  the  double-humped  response; 
curve  characteristic  of  overcoupled 
circuits)  move  away  from  the  mid- 
frequency  as  L,n  is  increased.  The 
response  of  this  circuit  is  similar  to 
that  for  a  double-tuned  inductively- 
coupled  transformer  in  which  the 
mutual  inductance  is  equal  to  the 
common  inductance  L,n.  For  the 
series-type  coupling,  only  one  limit 
frequency  is  affected.  ^ 

We  next  consider  the  selectivity 
far  from  resonance.  Circuits  of  Figs. 
2B  and  2D  are  similar.  For  both 
these  circuits  the  low-frequency 
skirt  is  the  steepest  obtainable, 
whereas  there  is  some  flattening  out 
on  the  high-frequency  side  below 
about  60  db.  down.  The  response  of 
the  circuit  of  Fig.  2A  is  somewhat  better  on  the 
high-frequency  side  but  somewhat  worse  (below 
about  80  db.  down)  on  the  low- frequency  side. 
The  circuit  of  Fig.  2C  has  the  steepest  obtainable 
response  on  the  high-frequency  side  but  is  very 
much  the  worst  of  the  lot  on  the  low-frecjuency 
side,  since  the  response  starts  to  rise  again  about  8 
kc.  off  on  the  low  side  (for  circuit  values  to  be 
considered  later).  At  20  kc,  component  values 
limit  us  to  the  use  of  the  type  of  coupling  shown 
in  Figs.  2A  and  2D,  since  practical  values  for  Cm 
are  rather  high.  It  can  be  shown  that  the  coeffi- 
cients of  coupling  for  these  two  circuits  are 

k  ~  ~j~,  and  k  ■^  —  -7^ 

In  general,  the  best  off-channel  response  will  be 
obtained  by  the  use  of  combinations  of  both  these 
circuits,  as  in  the  circuit  of  Fig.  3.  For  maximum- 
flat  response,  the  circuits  should  be  critically 
coupled;  that  is,

coupled  circuits,  since  for  the  case  con- 
sidered, L  >»  Lm  and  L  »  Li 
(Fig.  5).  And  because  the  coil  is  sur- 
rounded by  a  material  of  very  high 
permeability,  the  coupling  between  the 
two  parts  of  the  coil  is  almost  perfect 
and  the  circuit  approximates  an  ideal 
autotransformer,  transforming  imped- 
ance and  voltage. 

Practical  Circuits 


Fig.  3  — ■  Shunt-  and  series-coupling  circuits  can  be  combined  for

With  critical  coupling,  the  flat-topped  character 
of  the  over-all  response  curve  is,  if  anj^thing,  im-

In  general,  any  degree  of  selectivity,  approaching 
the  ideal  flat-top  response,  can  be  obtained  b}-

is  wired  so  that  a  Selectoject  can  be  used  with  the 
amplifier.  When  the  Selectoject  is  not  in  use,  an 
octal  plug  must  be  used  to  jump  Pins  6  and  8. 
Other  t\-pes  of  audio  filters  could  also  be  used.  (A 
double-tuned  critically-coupled  selective  ampli- 
fier tuned  to  1  kc,  with  a  bandwidth  of  30  cycles, 
has  been  experimentally  used  by  the  author  with 
very  e.xcellent  results.)  The  decoupling  l)etween 
stages  may  look  elaborate,  but  adequate  by- 
passing is  quite  difficult  at  20  kc,  where  a  0.1-/uf. 
condenser  looks  like  80  ohms.  After  some  experi- 
mentation the  decoupling  shown  was  adopted  as 
a  means  of  completely  isolating  the  stages  so  the 
response  curves  are  as  calculated  and  not  as 
modified  by  the  regeneration  inti-oduced  l)y  the

*  Pot  cores  D-25/17,5  have  now  been  superseded  by  type 
D-25/16  (i.e.,  the  total  height  of  the  assembly  is  16  mm. 
rather  than  17.5  mm.).  The  only  important  advantage  of 
these  new  pot  cores  is  that  a  greater  air  gap  is  available  than 
with  the  older  type.  The  maximum  air  gap  in  the  former 
type  was  0.5  mm.,  whereas  in  the  new  type  0.85  mm.  air  gap 
is  available  for  the  Grade  IIIB2  material.  Grade  IIIBl  is 
recommended  for  frequencies  below  20  kc.  whereas  IIIB2 
is  recommended  for  frequencies  above  20  kc.  At  20  kc. 
similar  Qs  can  be  obtained  with  either  type.  For  frequencies 
above  100  kc,  use  Type  IIIB3.  It  is  recommended  that,  if 
this  new  line  of  cores  is  available.  Type  IIIB2  with  an  air 
gap  of  0.85  mm.  be  used  at  20  kc,  since  this  will  result  in  a 
slightly  imjirovcd  temperature  stability  (here  A''  =  93  VL). 

These  new  cores  have  not  been  used  by  tne  a>:thor,  but 
it  is  thought  that  Qs  between  150-170  should  be  easil.y

a  Type  25/17,5  pot  core  with  an  air  gap  of  1  mm.  This  air 
gap  was  experimentally  ground  by  hand.  However,  it  is  not 
recommended  that  the  air  gap  be  altered  unless  accurate 
micrometers  are  available  to  insure  a  uniformity  of  the 
cores.  The  material  is  very  hard  and  brittle,  and  grinding 
even  a  few  fractions  of  a  millimeter  off  the  slug  is  a  long, 
tedious  job.

Here's  how  an  army  huj;  was  r<'w«»rke<l 
into  a  hi^li-speeti  e.k.ni. 


DURiN(i  the  past  few  years  many  excellent 
electronic!  key  designs  have  appeared  in 
QST,  and  from  these  articles  amateurs  as 
well  as  commercial  operators  have  built  a  numhei- 
of  efficient  keys.  Listen  any  week  night  to  one  of 
the  fast  c.w.  amateur  trafhc  nets  and  you  will 
untlerstand  what  I  mean  and  what  a  large  num- 
ber are  being  used  at  the  present  time. 

Some  years  back  I  built  an  electronic  key 
from  a  circuit  in  QST  and  found  it  very  satis- 
factory. In  the  QST  article  it  was  stated  that 
the  difference  between  operating  the  conven- 
tional style  bug  and  an  electronic  key  was 
that  j'ou  operate  the  bug  and  the  electronic 
key  operates  you.  I  found  this  to  be  true. 

When  comparing  regular  hug  operating  with 
tape  transmission  you  will  find  the  bug  has  a 
characteristic  style  for  each  individual  because 
each  of  his  hand  actions  is  reflected  in  his  trans- 
mission. At  high  speeds  the  characters  are  sharp 
and  not  uniform.  On  the  other  hand,  the  electronic- 
key  approaches  tape  very  closely  and  the  indi- 
vidual operator's  characteristics  are  not  present 
l)ecause,  as  already  mentioned,  you  have  to  make 
your  operating  conform  with  the  time-constant 
circuits,  and  as  you  coordinate  with  them  you 
accjuire  rhythm  to  conform.  Really  most  of  the 
actual  forming  of  the  characters  is  out  of  your 
control  —  all  you  control  is  the  spacing  between 
the  words  and  characters.  And  now  we  come  to 

our  story.

At  a  speed  of  30  w.p.m.  there  are  appro.xi- 
mately  25  time  units  per  second,  figuring  5  char- 
acters of  two  dashes  and  one  dot  each  per  word 
and  giving  three  units  to  a  dash,  one  to  a  dot, 
one  to  the  space  between  each,  and  two  units 
l)etween  characters.  The  electronic  kej^  will  allow 
\ou  three  time  units  for  going  from  a  dash  to 
dot  (if  the  dash  is  self-completing)  compared  with 
onl\'  one  unit  when  returning.  So  you  see,  in  order 
to  keep  a  good  rhythmic  style  of  transmitting  at 
high  speed,  you  rec|uire  an  operating  mechanism 
with  fast  action  and  small  movement  when  going

from  the  dot  to  the  dash  side,  since  the  available 
time  is  only  about  one  twenty-fifth  of  a  second. 
I  had  previously  used  several  different  styles 
of  keying  devices  but  was  never  satisfied  with 
them  because  as  the  speed  increased  it  was 
difficult  to  keep  constant  rhythm  because  of 
excess  motion  and  play.  Keeping  the  above  in 
mind,  a  study  was  made  of  several  styles  of 
keying  mechanisms  both  in  operating  and  on  the 
bench,  with  the  objective  of  constructing  a 
device  having  fast  action,   self  centering,   and

dle in  going  from  dot  to  dash, 
the  arm  returns  to  center 
without  overshoot  when  re- 
leased. Practically  any  "bug" 
will  lend  itself  to  modifica-

Communications  Receiver  Hints  for  the 

V.H.F.  Man 

Simple  Modifications  To  Improve  Results  with  Crystal- 
Con  trolle  d  Con  verters 

BY  EDWARD  P.  TILTON,  WIHDQ 


ONCE  you've  used  a  crystal-controlled  con- 
verter for  v.h.f.  reception  you'll  never  be 
satisfied  with  less.  The  stability  afforded  by 
crystal-controlled  injection  has  probably  been  the 
greatest  single  factor  in  the  vast  improvement  in 
reliable  coverage  that  v.h.f.  men  have  achieved 
in  the  last  few  years.  But  this  has  not  come  about 
without  introducing  a  few  objectionable  features 
along  with  the  benefits. 

Spurious  responses,  for  instance  are  much 
more  troublesome  when  the  i.f.  is  tuned  and  the 
fi'oiit  piid  of  tlio  i-pfoiving  system  is  brnadliandod. 


1  iiR'  luniiij;  ul  llic  goiioral-cox  erati,e  dial  on  most  com- 
munications receivers  can  be  accomplished  through  the 
installation  of  a  vernier  drive  mechanism.  This  can  be 
mounted  on  a  plate  that  can  be  removed  at  any  time, 
thus  preventing  any  permanent  defacing  of  the  recei\  er. 

And,  as  many  a  converter  user  has  found  out  too 
late,  there  are  very  few  communications  re- 
ceivers that  have  both  tuning  rate  and  tuning 
range  adequate  for  the  job  of  covering  a  4-mega- 
cycle  spread  at  7  or  14  Mc. 

The  problem  of  unwanted  signals  has  already 
been  treated  in  some  detail  in  QST  by  Van  Duyne 
and  Treptau.^  Their  discussion  was  concerned 
mainly  with  converter  circuit  features  that  help 
to  solve  the  problem.  They  showed  methods  for 
making  the  converter  response  curve  flat-topped, 
with  steep-sloping  skirts.  They  also  pointed  to 
the  need  for  keeping  harmonics  and  subharmonics 
out  of  the  energy  supplied  to  the  mixer  stage  from 
the  ostdllator-multiplier  chain. 

After  the  measures  they  describe  have  been 
taken,  if  there  is  still  appreciable  interference 
from  signals  riding  through  at  the  first  inter-

Design,"  February,  1953,  QST,  page  52. 


mediate  frequency,  some  attention  must  be  paid 
to  the  receiver  with  which  the  converter  is  used. 
Signals  at  5  to  20  Mc.  are  likely  to  be  very  strong 
at  times.  It  is  hard  to  find  a  4-megacycle  spread 
anywhere  in  this  region  where  leak-through  won't 
occur  at  least  part  of  the  time,  even  with  fairly 
good  shielding.  But  our  experiences  with  TVI 
have  taught  us  that  things  that  look  like  shielding 
and  grounding  may  not  actually  be  doing  the  job 
we  require. 

Take  the  antenna  terminals  used  on  many  of 
today's  receivers,  for  example.  Fig.  1  shows  a 
typical  arrangement.  A  small  bakelite  strip  on 
the  back  of  the  receiver  has  three  screw  terminals. 
The  first  is  connected  inside  the  chassis  to  a 
ground  lug  adjacent  to  the  tei-minal  board.  The 
other  two  are  the  "doublet"  terminals,  to  be 
used  with  any  balanced-line  feed.  When  an  end-fed 
or  coax-fed  antenna  is  used  a  jumper  connects 
Terminals  1  and  2,  "grounding"  them,  and  pre- 
sumal)ly  also  outer  conductor  of  the  coax.  The 
inner  conductor  is  connected  to  Terminal  3.  The 
same  arrangement  is  used  when  coax  from  a 
v.h.f.  converter  is  run  to  the  receiver  antenna 
terminals. 

That  this  method  of  connection  can  lead  to 
much  i.f.  interference,  through  no  fault  of  the 
receiver  or  converter,  was  discovered  recently 
when  a  new  NC-183D  was  placed  in  service  at 
WlHDQ.  When  propagation  was  good  in  the 
7-Mc.  region,  Radio  Moscow  and  the  BBC  gave 
us  considerable  trouble.  Other  signals  around  9 
Mc.  were  almost  equally  annoying.  Yet  these 
signals  had  been  no  more  than  barely  perceptible 
on  a  rack-model  HRO-7  used  previously.  (The 
antenna  connections  on  the  rack  job  were  inside

the  metal  dust  cover.)  When  a  converter  that 
used  14  to  18  Mc.  was  tried,  the  i.f.  interference 
was  intolei-able  on  the  new  receiver. 

Having  had  some  previous  experience  with  this 
sort  of  thing,  we  laid  a  screwdriver  blade  across 
from  an  exposed  bare  metal  part  on  the  183D 
panel  to  the  chassis  of  the  converter.  Down  went 
the  i.f.  QRM!  Yet  what  was  wrong  with  the  coax 
braid,  already  connecting  the  converter  and  re- 
ceiver chassis?  Nothing  —  except  that  the  con- 
nection to  the  chassis  is  on  the  inside  of  the  re- 
ceiver, as  showni  in  Fig.  1.  There  is  no  connection 
to  the  outside  of  the  chassis,  except  through  the 
rivet  at  the  left  edge  terminal.  Result:  The  wire 
from  Terminal  1  to  the  ground  rivet  is  a  nice  little 
coupling  loop,  and  the  converter  is  effectively  an 
"antenna"  for  signals  at  the  intermediate  fre- 
quency ! 

The  cure  is  obvious.  Remove  the  loop  connec- 
tion on  the  inside  of  the  chp.ssis  and  make  the 
ground  on  the  outer  wall.  Use  braid  or  copjjer 
strap,  so  that  Terminals  1  and  2  are  really  at 
ground  potential,  outside  the  receiver. 

If  you  have  a  very  l)ad  i.f.  interference  problem 
(like  a  40-meter  ham  running  a  kilowatt  in  the 
next  block)  you  may  want  to  go  a  step  further 
and  shield  the  antenna  terminals.  On  the  XC- 
183D  this  was  matle  very  easj-  by  the  manuf:',c- 
turer;  he  provided  the  shield,  ready-m;ide,  over 
the  speaker  terminals.  By  removing  the  bottom 
plate  you  have  ready  access  to  the  Ijack  of  the 
terminals  on  the  rear  wall  of  the  chassis.  Remove 
the  short  screws  that  hold  the  anteinia  terminal 
l>oard  and  replace  them  with  ones  at)out  i'4  inch 
long,  with  the  heads  inside  the  receiver  and  re- 
taining nuts  outside.  The  shield  box  can  then  be 
mounted  over  the  antenna  terminal  assembly, 
outside  the  chassis,  in  the  same  way  that  it 
originally  covered  the  speaker  terminals.  If  this 
doesn't  cure  your  i.f.  leak-through  problems  you 
need  to  go  over  the  W2MLX-K2CEM  sugges- 
tions' again. 

Of  course,  the  reall)'  businesslike  way  to  handle 
the  shielding  of  the  antenna  input  connections 
is  to  install  a  coaxial  fitting  on  the  rear  of  the 
receiver,  and  eliminate  the  terminal  board  en- 
tirely. The  steps  outlined  above  are  for  timid 
souls  who  can't  bring  themselves  to  drill  holes 
in  a  commercial  receiver,  even  in  the  back.  If 
your  receiver  and  converter  are  close  together,  try 
a  strap  bond  between  the  two  chassis. 

And  here's  an  operating  hint  that  helps  to 
reduce  i.f.  interference.  If  your  converter  has  an 
i.f.  amplifier,  run  its  gain  as  high  as  possible, 
and  the  "r.f.  gain"  on  the  receiver  as  low  as  pos- 
sible. Where  the  i.f.  pick-up  is  the  result  of  poor 
shielding  in  the  receiver  this  will  help  appre- 
ciably. If  the  i.f.  signals  are  fed  through  the  con- 
verter front  end,  it  will,  of  course,  make  no  dif- 
ference. 

What  To  Do  About  Tuning  Rate? 

It's  a  sad  fact  of  two-dial  receiver  design  that 
the  general-coverage  dial  chases  the  kilocycles 
by  just  too  fast  to  make  for  easy  tuning  of 
v.h.f.   signals.   And  the  bandspread  dial  never 


covers  enough  tuning  range  to  be  of  much  use, 
except  to  the  low-edge  v.h.f.  DX-hound.  Single- 
dial  receivers  like  the  HRO,  SX62,  BC-342, 
BC-348,    SPtJOOJX    and    SX-73    are    somewhat

better,  but  onh'  the  last  three  can  be  said  to  come 
close  to  the  ideal  in  the  tuning-rate  department. 

Some  improvement  (!an  l)e  achieved  by  select- 
ing the  intermeiliate  fretjuency  according  to  the 
receiver's  qualifications  as  to  tuning  rate.  Quite 
a  few  two-dial  receivers  spread  out  the  kilocycles 
more  at  the  low  edge  of  the  various  ranges.  The 
SX-71,  S-76,  NC-88  and  NC-y8,  for  examijle, 
tune  much  better  at  5  Mc.  than  at  7.  All  receivers 
tune  faster  on  each  higher  band.  The  kilocj'cles 
go  by  twice  as  fast  at  14  Mc.  as  they  do  at  7. 

Nearly  all  inexpensive  two-dial  receivers  are 
next  to  useless  for  the  crystal-converter  man; 
they  tune  too  fast  on  any  range.  The  solution, 
then,  is  to  slow  dowii  the  movement  of  the 
general-coverage  dial,  to  give  us  fewer  kilocj-cles 
per  degree  of  knob  rotation.  Fortunately,  this  can 
be  done  without  making  any  permanent  modifi- 
cations in  the  receiver  that  might  impair  its  resale 
value  or  appearance. 

The  photographs  show  how  this  is  done.  The 
example  is  the  NC-98,  but  we've  used  the  same 
general  method  on  the  SX-71,  S-76,  HQ-140-X 
and  NC-183D  with  equally  satisfactory  result^ 
Almost  any  vernier  drive  can  be  used,  the  first 
example  shown  being  a  Croname  type  599  plane- 
tary drive.  A  metal  mounting  plate  can  be  cut  and 
bent  to  fit  almost  any  receiver,  so  no  specific 
dimensions  are  given  here. 

Use  a  volume  control  nut,  a  chassis  retaining 
screw,  or  any  hand}'  removable  screw  or  nut  that 
appears  on  your  front  panel  to  hold  the  plate  in 
place.  The  "  CWO-Manual-AVC  "  switch  mount- 
ing nut  is  used  on  the  NC-98.  Cut  the  sheet 
aluminum  plate  to  suit  your  taste,  mount  the 
vernier  drive  in  place,  and  you  have  a  5-to-l 
reduction  drive  that  will  give  you  a  tuning  rate 
on   the  general-coverage  dial  that  will  closely

A  5-Band  Antenna  Coupler 

Simplifying  the  "All- Band"  Transmitter  Loading  Problem 
BY  LEWIS  G.  McCOY,  WIICP 


A  RECENT  ARTICLE  ill  QST  described  the  con- 
struction and  use  of  a  standing-wave-ratio 
-  bridge.'  It  was  pointed  out  that  when  the 
s.w.r.  bridge  was  used  in  conjunction  with  an  an- 
tenna coupler,  one  could  easily  match  the  output 
from  his  transmitter  to  the  antenna  system.  Ex- 
cept for  a  few  special  types  of  antennas,'-^  nearly 
all  multiband  systems  need  an  antenna  coupler  to 
match  the  transmitter  output  to  the  feedline.  If 
one  is  fortunate  enough  to  have  a  separate  an- 
tenna for  each  band,  and  each  antenna  is  fed  with 
an  untuned,  or  "flat  "  (lows.w.r.),  Une,  an  antenna 
coupler  is  of  course  not  required.  However,  most 
of  us  have  to  struggle  along  with  a  multiband 
antenna  and  use  a  tuned  line.  The  purpose  of  this 
article  is  to  describe  a  coupler  that  has  enough 
flexibilitj'  to  match  practically  any  antenna  sj'S- 
tem  the  average  ham  can  dream  up.  In  addition, 
for  the  benefit  of  the  beginner,  a  few  simple  an- 
tenna sj-stems  will  be  described. 

The  Circuit 

There  are  two  basic  circuits  used  in  antenna 
couplers:  series  or  parallel  tuning.  Which  circuit 
is  used  depends  upon  the  antenna  and  feedline 
length  in  terms  of  wavelengths.  In  order  to  take 
care  of  the  different  conditions  one  is  likely  to  en- 
counter, an  antenna  coupler  should  be  designed 
to  use  both  types  of  tuning.

capacitors  shown  are  actually  one  split-stator 
variable  —  simple  switching  takes  care  of  getting 
the  different  circuits.  A  fixed  link  is  used  on  the

plugging  in  a  suitably-connected  bar  plug  —  the 
letters  beneath  the  plugs  correspond  to  the  four 
circuit  conditions  of  Fig.  1.  Li  and  L2  are  both 
mounted  on  another  plug  bar  —  only  two  coils 
are  required  to  cover  the  bands  80  through  10 
meters.  Intermediate  values  of  inductance  are 
obtained  by  shorting  turns  with  clip  leads  per  ma- 
nently  mounted  on  the  coil  bar,  as  can  be  seen  in 
one  of  the  photographs. 

Construction 

Although  the  parts  for  the  antenna  coupler 
might  l)e  mounted  on  a  wooden  base,  we  elected 
to  mount  them  on  a  3  X  5  X  10-inch  chassis. 
The  condenser  spacings  and  coil  wire  sizes  are 
adequate  to  handle  powers  up  to  about  500  watts 
input  to  the  transmitter.  Since  the  Novice  cannot 
run  more  than  75  watts,  the  cost  of  the  unit  for 
low-powered  applications  can  be  reduced  by  sub- 
stituting a  smaller  capacitor  of  the  same  range 
tor  C'2.  However,  the  Novice  can  build  for  future 
high-power  days  by  using  components  with  the

ratings  given  in  the  caption,  with  the  assurance 
that  the  coupler  will  work  just  as  well  for  him  as 
it  will  for  the  ham  with  500  watts. 

The  two  coils  and  their  links  are  made  from  a 
single  length  of  B  &  W  3906  coil  stock.  To  make 
the  80/40-meter  coil,  first  count  off  46  turns  of 
the  coil  stock  and  cut  this  piece  from  the  stock. 
Then  unwind  one  turn  from  each  end.  This  will 
provide  leads  to  connect  to  the  jack  bar  plug. 
Next,  cut  the  19th  turn  from  each  end,  making 
the  cut  at  the  top  of  the  coil  (calling  the  side 
where  the  outside  leads  come  off  the  "bottom"). 
The  ends  of  the  wires  at  these  cuts  are  separated 
from  the  form  and  brought  around  to  the  bottom 
of  the  coil.  We  now  have  three  coils  of  18  turns,  6 
turns,  and  18  turns.  The  6  turns  at  the  center 
forms  the  link,  Li.  The  inside  ends  of  the  two 
18-turn  sections  should  be  soldered  together. 
This  gives  a  coil  for  Lo  consisting  of  36  turns, 
with  the  6-turn  link,  L\,  at  the  center.  The  leads 
are  inserted  in  the  jack  bar  plug  (Millen  40305) 
and  soldered.  The  last  step  is  to  mount  clip  leads 
on  the  coil  ends,  so  that  a  portion  of  the  coil  can 
be  shorted  out  for  40-meter  operation. 

The  20/15/10-meter  coil  is  made  up  in  a  simi- 
lar manner.  The  original  piece  of  coil  stock  con- 
sists of  14  turns.  The  completed  L<>  has  8  turns, 
4  each  side  of  center,  with  a  2-turn  link  for  L\. 

No  specifications  are  given  for  tap  points  be- 
cause these  points  may  vary  with  the  antenna 
system.  The  coil  and  shorting  bar  hold(>rs  are 
made  from  Millen  41305  jack  bars. 

Using  the  Coupler 

Let's  assume  we  have  a  half- wave  dipole,  135 
feet  long,  fed  at  the  center  with  open-wire  line. 
We'll  start  out  first  on  80  meters  and  work  down 
through  10  meters,  making  notes  on  each  setting 
of  the  coupler  in  order  to  have  a  permanent  rec- 
ord. As  pointed  out  in  the  s.w.r.  bridge  article,' 
one  of  the  best  methods  for  adjusting  the  coupler 
is  with  a  bridge.  The  80-meter  coil  is  plugged 
into  the  unit  and  the  feeders  are  attached  to  the 
antenna  terminals.  For  a  start,  we'll  use  plug  B, 
which  will  give  us  high-C  parallel  tuning.  The 


•  One  of  the  stumbling  blocks  among 
new  amateurs  is  the  problem  of  properly 
coupling  the  antenna  to  the  transmitter. 
A  flexible  antenna  coupler  that  will  han- 
dle a  wide  variety  of  situations  is  the  solu- 
tion, and  in  this  article  WIICP  describes 
such  a  device  and  how  to  use  it.  Since  it 
will  handle  powers  up  to  several  hundred 
watts,  it  won't  have  to  be  rebuilt  if  and 
when  you  increase  power. 


bridge  is  connected  by  coa.x  fine  to  the  trans- 
mitter temporarily  with  nothing  connected  to 
the  output  side  of  the  bridge.  The  transmitter  is 
set  up  near  3500  kc,  or  3700  kc,  if  j'ou  are  a 
Novice  license  holder,  and  full-scale  reading  is  set 
on  the  bridge  meter  by  adjusting  the  transmitter 
output  or  excitation.  The  coax  line  from  the 
coupler  is  then  connected  to  the  output  side  of 
the  bridge.  The  controls  on  the  transmitter  are 
left  as  they  were  for  this  particular  frequency 
setting. 

The  two  condensers,  Ci  and  C2,  are  then  tuned 
for  a  null  indication  on  the  s.w.r.  bridge  meter.  It 
should  be  possible  to  get  a  reading  of  zero  or  very 
close  to  it.  If  a  good  null  isn't  obtained,  try  the 
other  plugs,  starting  with  A  and  working  through 
D.  It  may  be  necessary  to  tap  in  toward  the 
center  of  the  coil,  but  keep  the  taps  as  close  to 
the  coil  ends  as  possible.  Once  a  good  null  is  ob- 
tained, mark  down  the  settings,  because  as  long 
as  the  same  antenna  system  is  used,  the  settings 
will  remain  the  same.  The  procedure  outlined 
above  can  be  made  for  each  25  kc.  throughout  the 
80-meter  band,  noting  the  settings  at  each  spot 
frequency.  In  this  way,  one  can  quickly  change 
frequency'  and  alwa3's  be  sure  the  system  is  tuned 
on  the  button. 

For  40  meters,  the  same  procedure  is  followed, 
e.xcept  that  the  coil  is  tai)ped  down  from  the  ends 
until  a  good  null  is  obtained.  With  the  antenna 
system  used  for  testing  the  coupler,  the  taps  were 
placed  at  eight  turns  in  from  the  ends.  However, 
different  antenna  systems  may  take  different  tap 


l^op  view  of  the  coupler 
with  the  high-frequency -range 
coil  in  place.  The  shorting-bar 
assembly  is  apparent  behind 
the  coil.  The  low-frequency 
coil  and  additional  shorting 
bars  are  shown  at  the  right.

points,  so  the  correct  spots  must  be  found  ex- 
perimentall,y.  Always  keep  the  tap  points  as  close 
to  the  ends  of  the  coil  as  possible,  consistent  with 
a  low  s.w.r.  Since  the  turns  on  the  coil  are  too 
closely  spaced  to  accommodate  alligator  clips, 
clip  points  can  be  made  from  ordinary  soldering 
lugs  soldered  to  the  coil  at  the  proper  points. 

After  the  JO-meter  settings  are  noted,  similar 
steps  can  be  followed  on  20,  15  and  10  meters. 
The  correct  settings  for  the  taps  are  likely  to  be 
more  critical  than  for  the  lower-frequency  bands. 
In  addition,  it  may  be  necessary  to  have  more 
than  one  set  of  tap  points  for  the  entire  10-meter 
band. 

With  the  procedure  outlined  above,  it  is  of 
course  assumed  that  one  has  an  s.w.r.  bridge  or 
can  borrow  one.  If  none  is  available,  the  coupler 
can  be  tuned  using  an  output  indicator.  An  r.f. 
ammeter  can  be  inserted  in  series  with  one  of  the 
feeder  wires  and  the  coupler  tuned  for  maximum 
output,  as  indicated  by  the  greatest  reading  ob- 
tainable on  the  ammeter.  This  is  not  as  accurate 
as  the  bridge  method  of  adjustment,  because  one 
cannot  be  sure  the  line  between  the  transmitter 
and  the  coupler  is  perfectly  matched.  Dial  lamps 
in  series  with  the  feedline  or  tapped  across  a  sec- 
tion of  line  will  also  serve  as  output  indicators,  as

indicator,  and  either  of  the  two  systems  shown  above 
can  be  used.  In  A,  a  single  dial  lamp  with  one-foot  leads 
is  clipped  onto  the  feedline.  As  the  transmitter  and  cou- 
pler are  tuned  to  maximum  output,  the  dial  lamp  will 
light  up.  It  may  be  necessary  to  move  the  clip  leads  up 
the  line  to  find  a  point  where  sufficient  coupling  is 
obtained.  At  B,  the  dial  lamps  in  parallel  are  connected 
in  one  of  the  feeders.  To  start  out,  all  three  bulbs  should 
be  connected  to  prevent  possible  burn-out.  They  can 
be  disconnected  one  at  a  time  until  the  best  indication  is 
obtained.

Center-Fed  Antennas 

A  center-fed  antenna  doesn't  have  to  be  a 
specific  length  to  work  well.  If  you  can  make  the 
antenna  a  half  wavelength  long  at  the  lowest 
band,  fine  and  dandy.  But  if  your  (JTH  is  such 
that  putting  u[)  a  half-wave  antenna  would  mean 
tying  the  far  end  to  your  neighbor's  TV  antenna,

ary, 1955. 


In  this  view  the  link  capacitor  is  shown  at  the 
bottom  and  the  tuning  capacitor  at  the  top.  The  line

cable. 


use  a  little  discretion  and  compromise  with  the 
ideal.  A  slightly  shorter  antenna  won't  show  an 
appreciable  difference  in  performance.  The  im- 
portant thing  about  a  center-fed  antenna  is  to  be 
sure  that  the  feedline  is  connected  at  the  exact 
center  of  the  antenna  and,  if  possible,  that  the 
feedline  runs  away  from  the  antenna  at  right 
angles  for  a  considerable  distance.  Some  ama- 
teurs do  this  by  bringing  the  feedline  straight 
down  from  the  horizontal  antenna  to  a  mast  or 
pole  and  then  running  the  feedline  into  the 
shack.  The  horizontal  section  of  the  feedline 
should,  of  course,  be  high  enough  to  clear  the 
heads  of  any  pedestrians. 

It  is  a  good  idea  to  make  the  length  of  the 
feedline  plus  one-half  the  antenna  length  a 
multiple  of  a  quarter  wavelength  at  the  lowest 
operating  frequency.  A  quarter  wavelength  is 
found  by  dividing  246  by  the  operating  frequency 
in  Mc.  As  an  example,  suppose  the  lowest  oper- 
ating frequency  is  3.7  Mc;  246  -i-  3.7  =  663^ 
feet,  so  half  the  antenna  plus  the  feedline  would 
want  to  be  66 K  (impractical  because  it  makes 
either  the  antenna  or  the  feedline  too  short),  133, 
or  200  feet  long.  If  the  antenna  is  100  feet  long, 
half  of  this  is  50  and  the  feedline  should  be  either 
83  (133  -  50)  or  150  (200  -  50)  feet  long.  But  if 
these  feedline  lengths  are  inconvenient,  don't 
worry  about  it  too  much.  Put  up  the  antenna 
you  can,  with  the  feedline  coming  away  from  the 
center,  and  try  tuning  it  on  the  bands  available 
to  you.  There  are  some  combinations  that  turn 
out  to  be  a  little  awkward,  but  the  antenna 
coupler  can  handle  a  wide  variety  of  combina- 
tions. If  you  run  up  against  one  it  can't,  try 
lengthening  or  shortening  the  feedline  a  few  feet. 

End-Fed  Antennas 

The  foregoing  flexibility  of  antenna  length 
does  not  apply  to  the  end-fed  "Zepp"  antenna. 
In  this  case,  if  the  feedline  is  not  to  radiate,  the 
antenna  length  should  be  a  half  wavelength  long, 
or  a  multiple  of  a  half  wavelength.  Formulas  and 
charts  for  these  lengths  are  given  in  the  Hand- 
book. However,  with  the  light  antenna  length,  the 
l)receding  remarks  about  tune-up  procedure  hold, 
except  that  the  preferred  over-all  lengths  involve

QST- Volume  III 


Part  Hi  —  Forewoi'd  to  Sumner  B.  Young's  (IV0CO)  Index 


The  use  of  low-powered  spark  sets,  operating 
on  wavelengths  below  200  meters,  as  a  means  of 
QRM  avoidance,  was  a  somewhat  more  practical 
suggestion;  but  it  is  probable  that  very  few  ama- 
teurs followed  it.  The  main  trouble  was  the  lack 
of  receivers  capable  of  being  tuned  down  to  100, 
150,  or  175  meters;  and  this  difficulty  was  to 
continue  for  some  time.^' 

An  article  describing  a  spark-coil  transmitter 
for  operation  on  100,  150,  and  200  meters  (first 
suggested  in  a  letter  published  at  26  to  27,  Octo- 
ber 1919),  will  be  found  at  13  to  14,  February 
1920. 

An  improved  version  of  a  spark-coil  transmit- 
ter was  later  described  in  Volume  IV  (b\'  Scott) 
at  pages  55  to  56  of  the  December  (1920)  issue. 
Scott  operated  on  180  meters,  and  he  suggested 
the  use  of  waves  down  as  low  as  100  meters.^^ 

In  the  February  (1920)  issue,  at  pages  23  to 
24,  and  26,  there  is  a  very  interesting  account  of 
the  discussions  which  occurred  at  the  first  Boston 
Inter-Club  Convention.  This  meeting  was  called 
by  Guy  R.  Entwistle,  and  was  held  on  November 
20,  1919.  (See  14,  January  1920.)  Among  other 
things,  the  use  of  wavelengths  of  150,  175,  and 
200  meters,  by  spark-coil  stations,  was  recom- 
mended.^* 

The  editor  of  QST  thought  well  of  this  idea; 
and  he  also  suggested  that  all  spark  stations  drop 
down  to  175  meters,  and  use  reduced  power,  for 
local  and  "moderately  short-distance  work."  ^* 
[italics  by  S.B.Y.] 

The  decisions  reached  at  the  Boston  Con- 
ference were  referred  to,  with  approval,  by  Mr. 
C.  A.  Service,  jr.  (Atlantic  Division  Manager  of 
the  ARRL),  at  pages  19  to  20,  in  the  Januarj^ 
(1920)  issue. 

The  most-efi'ective  method  of  dealing  with  the 
interference  problem,  however,  was  through  the 
use  of  "time  schedules,"  and  rules  of  operation, 
enforced  by  "strong"  local  or  regional  clubs  or 
associations. 

In  this  field,  the  Boston  Conference  (called  by 
Mr.   Entwistle)   deserves  credit  for  some  wise 


decisions;  although  its  recommendations  as  to  the 
enforcement  of  its  policies  were  not  as  practical 
as  those  which  were  later  developed  in  Chicago 
and  embodied  in  the  so-called  "Chicago  Plan." 

At  pages  19  to  20,  January  1920,  Mr.  Service 
stated : 

.  .  .  The  Division  Manager  wishes  to  mention  a 
movement  among  the  Boston  amateurs  which  has 
come  directly  to  his  notice,  that  will  sooner  or  later 
take  form  as  a  nationwide  movement  in  all  sections 
and  communities  where  any  radio  congestion  exists. 
There  was  a  meeting  held  of  representatives  of 
prominent  Boston  and  New  England  amateur  asso- 
ciations. .  .  .  The  situation  received  a  general  pre- 
liminary discussion,  the  point  of  \aew  of  the  spark 
coil,  the  experimenter,  the  relay  station  and  the 
local  amateur  being  presented  and  considered  and 
the  following  tentative  remedies  being  suggested. 

1.  Central  control  station  for  traffic  and  com- 
munication control,  to  see  all  have  a  fair  show  and 
no  one  encroaches  on  the  rights  of  others. 

2.  U.se  of  other  waves  besides  and  below  200 
meters  for  local  work. 

3.  Elimination  of  broadly  tuned  stations  and 
thoughtless  or  willful  interference. 

4.  Use  of  minimum  power  to  ensure  reliable 
communication. 

5.  Time  limits  for  local  and  long-distance  work. 

6.  Punishment  for  persistent  offenders. 
Amateurs  from  one  coast  to  the  other  have  been 

thinking  this  question  over  for  years  and  the  Boston 
convention  is  only  one  example  of  what  other  asso- 
ciations have  done  or  tried  to  do.^s 

There  was  also  some  curiosity,  on  the  part  of 
U.  S.  A.  amateurs,  as  to  what  kind  of  results  the 
Canadian  amateurs  were  obtaining,  if  they  were 
actually  using  certain  short  wavelengths  pre- 
scribed b}-  law  for  use  in  certain  locations. 

At  27,  September  1919,  the  plight  of  "Our 
Canadian  Cousins"  was  discussed  by  E.  T. 
Scholej',  of  Toronto: 

.  .  .  Perhaps  a  brief  resume  of  the  Government 
regulations  in  Canada  would  not  be  out  of  place. 
They  are  rather  hard  for  people  living  around  the 
Great  Lakes,  for  an  amateur  station  within  fi-\f3 
miles  of  a  government  or  commercial  station  or  a

1955,  QST;  "  QST —Volume  I"  appeared  in  October,  1954, 
QST;  "QSr  — Volume  II"  appeared  in  February,  1955, 
QST. 

[Footnote  20;  continued  from  p.  52,  March  QST] 
Re  these  transmitting  experiments,  Matthews  stated  (at 
19,  July  1920):  "...  Experiments  carried  on  between  the 
Great  Lakes  Naval  Radio  Laboratory  and  a  station  in 
Chicago  have  shown  that  signals  transmitted  on  under- 
ground ^\"ires  are  eciual  in  intensity  to  those  transmitted  on 
any  ordinary  aerial,  the  only  difficulty  being  the  tendency 
of  the  underground  wires  to  '  ground '  when  any  considerable 
voltage  is  applied.  For  this  reason  only  tube  transmitters 
may  be  used  with  any  satisfaction,  although  a  low-voltage 
<iuenched  set  was  used  in  these  experiments  with  fair 
results.   ..." 

My  guess  is  that  transmission  and  reception  of  waves 
shorter  than  600  meters  by  use  of  subterranean  or  submarine 
antennae    are    not    presently    practised.    Very-long-wave

reception,  by  submarine  or  subterranean  wires,  probably  has 
had  plenty  of  attention  from  Army  and  Naval  experts, 
recently.  But  amateurs  can  have  little  practical  interest  in 
such  matters.  The  waves  which  we  use  are  all  too  short  for 
such  techniques. 

'*  Armstrong's  superheterodyne,  described  in  the 
"classic"  article  at  5  to  9,  15,  February  1920,  was  said  to 
be  capable  of  reception  down  to  50  meters.  See  page  5, 
February  1920.  However,  these  receivers  were  rarities. 

The  Grebe  type  AGP  101  Short-Wave  Regenerative, 
first  advertised  in  QST  on  the  inside  front  cover  of  the 
September  (1916)  issue,  was  supposed  to  tune  down  as  low 
as  150  meters.  I  suspect  this  was  to  allow  easy  tuning-in 
of  a  200-meter  signal. 

The  Grebe  CR-5,  CR-8,  and  CR-9  receivers,  as  adver- 
tised in  the  fall  of  1921,  had  a  bottom  tuning  range  of  150. 
See  74,  September  1921;  78,  October  1921;  71,  September 
1921;  and  97,  October  1921  —  all  in  Volume  V.

route  of  navigation  is  restricted  to  a  wavelength  of 
50  meters  for  transmission.  Up  to  25  miles  distance 
the  wavelength  is  100  meters;  seventy-five  miles, 
150  meters.  The  power  input  at  the  transformer 
terminals  is  limited  to  J^  kw.   .  .  , 

Later,  some  "'relaxation"  was  allowed: 
On  December  30,  1919,  the  Department  of  the 
Naval  Service,   at  Ottawa,   authorized  all  Ca- 
nadian amateurs  "on  the  Great  Lakes  and  River 


St.  Lawrence,  from  Port  Arthur,  Ontario,  to 
Quebec,  P.  Q.,  to  use  a  transmitting  wavelength  of 
200  meters  until  the  reopening  of  navigation, 
approximate^  the  15th  of  April,  1920."  This 
concession  was  stated  (in  the  Order  itself)  to  be 
''in  the  nature  of  an  experiment";  and  the  De- 
partment further  announced  that  if  no  inter- 
ference resulted,  it  was  "prepared  to  consider  a 
permanent  amendment  to  the  regulations  re- 
garding wavelengths."  -^ 

The  incjuiry,  re  experiences  on  short  waves,  was 
as  follows: 

In  an  editorial  called  "Greetings,  CanadiansI" 
I-^ditoi-  \\'arner  announced  that  the  League's  Oper- 
ating Dei^artment  had  been  expanded  to  include 
Canadian  Amateur  Divisions.  Then  he  said  (at 
15,  January  1920) : 

.  .  .  Can't  we  be  of  assistance  in  working  out  your 
technical  problems?  You  are  invited  to  make  use  of 
QST  for  this  purpose.  Relay  transmission  on  50 
meters  is  an  entirely  new  field  to  most  of  us,  but  we 
are  sure  it  can  be  done.  QST  will  welcome  discussions 
and  articles  on  this  topic.  For  best  results,  should 
the  transmission  be  by  the  usual  spark  method,  by 
buzzer  modulated  v.t.  oscillators,  or  by  a  big  he- 
buzzer?  What  kir.d  of  a  receiver  will  we  have  to  have 
to  get  down  to  your  fifty-  or  seventy-five  meter 
wave?   .   .   . 

It  is  probable  that  our  "Cousins"  decided  to 
put  all  of  their  energies  into  efforts  to  obtain 
permission  to  operate  on  200  meters  during  part 
(or  all)  of  the  .year;  because  I  can  find  no  evi- 
dence, anywhere  in  the  first  5  volumes  of  QST. 
that  American  amateurs  were  ever  given  any 
useful  information  growing  out  of  any  actual  use

-■^  At  48,  June  1920,  Mr.  Bowden  Washington,  chief 
engineer  of  Cutting  &  Washington,  stated  (in  a  letter)  es 
follows:  "...  The  writer  some  years  ago  put  4.6  amperes 
into  an  antenna  15  feet  high  and  2.5  feet  long  at  a  wave- 
length of  80  meters  and  a  spark  frequency  of  1000.  ..." 
S)jark  sets  would  operate  on  100  and  150  meters,  all  right. 

At  64,  January  1921  (Volume  IV),  F.  B.  Llewellyn's  letter 
says  that  the  U.  S.  Navy  used  a  o2-meter  wave  for  short- 
distance  work  during  World  War  One  (type  of  set  not 
mentioned).

-5  At  1.3  to  14,  January  1920,  it  was  stated  that  the  prob- 
lem of  QRM  control,  at  various  centers,  was  becoming 
"most  formidable."  Local  clubs  were  urged  to  grapple  witli 
it,  and  were  also  invited  to  affiliate  witli  the  League.  The 
Traffic  Manager  recommended  local  control  of  QRjNI  be- 
tween the  hours  of  9  p.m.  and  midnight,  "education"  of  the 
joimger  element,  etc..  etc. 

In  March  (1920).  an  outstanding  article  on  "Radio  Club 
Organization."  by  F.  H.  Schnelland  R.  H.  G.  Mathews,  was 
publislied.  See  5  to  6.  21  to  22,  March  1920.

QST  for 


of  50-,  75-,  or  100-meter  wavelengths  by  the 
Canadian  hams.^^  An  opportunity  to  "discover 
something"  surely  was  missed. 

This  is  an  outstanding  example  of  "how  a 
lioise  can  be  led  to  water,  but  can't  be  forced  to 
<liink."  And  here,  the  "horse"  evidentlj'  did  not 
laiicy  the  looks  of  the  "water"  which  was  in  the 
short-wave  "trough."  The  50-,  75-,  and  100-meter 
waves  must  have  appeared  to  be  pretty  useless, 
except  for  short-distance  work  on  spark  transmitters. 
Amateur  tube  sets,  operating  on  waves  as  short 
as  these,  were  unknown;  and  when  it  came  to 
receivers,  most  hams  could  reach  onlj^  a  very 
short  distance  below  200  meters.  Personall\%  I 
can't  blame  the  Canadian  amateurs  for  acting 
as  the\'  did. 

The  real  lesson  appears  (to  me)  to  be  this:  In 
radio  communication  work,  that  which  appears 
useless,  or  of  little  value  "today,"  ma}'  be  of 
considerable  use,  and  of  high  value,  "tomorrow." 

A  small  amount  of  international  traffic  began 
to  be  handled  between  Canadian  and  U.  S.  A. 
amateur  stations,  at  a  few  points.-** 

The  League  and  its  members  could  not  give  all 
their  attention  to  the  technical  development  of 
amateur  radio,  bj-  an}'  means.  Postwar  da}s 
brought  a  wave  of  proposed  radio  legislation. 

The  leading  article  on  the  subject,  in  Volume 
III,  is  entitled  "The  Amateur  Situation,"  pub- 
lished at  5  to  6,  September  1919. 

This  re{)orts  a  visit  of  a  League  representative 
(or  representatives)  to  Washington,  and  the  dis- 
cover}' that  the  Secy,  of  the  Navy  had  addressed 
a  letter  to  both  houses  of  Congress,  setting  forth 
the  "Views  of  the  Navy  Department  in  connec- 

ing  references  in  Volume  IV:  adopted  in  Boston  (Entwistle). 
35,  July  1921;  Atlanta  Radio  Club  adopts  it  (Merritt's 
report),  37,  July  1921;  adopted,  with  modifications,  b.\ 
Cleveland  amateurs  (Mathews'  report),  47,  .\pril  1921;  a 
scheme  modeled  on  it  is  adopted  in  the  Minneapolis-St. 
Paul  (Minnesota)  area.  (Pray's  report),  38,  December  1920; 
advocated  for  country-wide  use  (by  Scholtes),  22,  April 
1921;  a  lecture  by  Mathews  inspires  adoption  of  a  similar 
scheme  at  Philadelphia,  42,  April  1921. 

-*8,  March  1920. 

Some  Canadian  hams  later  received  special  licenses  allow- 
ing year-round  operation  on  200  meters.  Canadian  9.\L  (at 
Toronto),  for  instance.  See  38,  June  1921  (Volume  IV). 

Note  that  the  Canadian  lianis  (despite  tlieir  hard  luck  in 
other  matters)  got  back  on  the  air  after  World  War  One 
sooner  than  we  did.  J.  O.  Smith  (at  16,  September  1919) 
reported  them  as  already  being  in  oijeration;  but  he  failed 
to  give  the  date  when  this  reopening  had  occurred. 

-'  At  28,  July  1920,  in  Service's  report,  there  is  a  state- 
nent  that  " W.  T.  Fraser,  District  Superintendent  Western 
New  York,  reports  that  tests  with  Toronto,  Ont.  were  very 
satisfactory.  No  trouble  was  experienced  in  working  them, 
but  since  navigation  was  opened  they  are  allowed  onlj-  (a) 
50  meter  wavelength.  .  .   ." 

At  34,  July  1920,  in  Russell's  report,  we  find  these  words: 
"...  with  the  opening  of  navigation  the  wavelength 
allowed  amateurs  automatically  dropped  to  the  old  50 
meters,  thus  pretty  effectively  cutting  off  any  long  distance 
work.  .   .  ." 

At  27,  August  1920  (Volume  IV),  Russell  notes  the  re- 
fusal of  the  Canadian  authorities  to  allow  the  Canadian 
amateurs  to  remain  on  200  meters  during  the  navigation 
season.  On  the  same  page,  he  remarks  that  "This  decision 
by  the  Naval  Department  emphasizes  what  has  been 
preached  by  all  the  leading  amateurs  of  this  Division  [the 
Ontario  —  S.  B.  1'.];  i.e.,  that  c.w.  transmission  is  the  only 
solution  for  amateurs  in  Ontario  compelled  to  work  on  so 
short  a  wave.  ..." 

At  31,  September  1920  (Volume  IV),  it  is  announced  that 


tion  with  certain  aspects  of  radio  communica- 
tion." (This  was  known  as  "Document  No.  165.") 

A  subcommittee  of  the  Senate  Committee  on 
Naval  Affairs,  headed  by  Senator  Poinde.xter, 
was  found  to  be  functioning  as  a  special  commis- 
sion to  stud}'  conditions.  It  was  then  reviewing 
the  status  of  "world-wide  radio"  problems. 

The  subcommittee  had  asked  the  Navy  De- 
partment to  tender  a  draft  of  a  law  embodying 


April  1955 


47 


the  desires  of  the  Navy,  as  expressed  in  "Docu- 
ment No.  165,"  so  that  the  subcommittee  could 
study  the  same. 

In  the  House  of  Representatives,  the  matter 
was  in  the  hands  of  the  Committee  on  Merchant 
Marine  and  Fisheries. 

The  article  (in  the  September,  1919,  QST) 
describes  the  contents  of  the  Secretary's  letter 
("Doc.  No.  165"),  as  follows: 

.  .  .  After  reviewing  the  situation  in  dctiiil  from 
the  Navy  standpoint,  the  letter  asks  (1)  the  ap- 
pointment of  a  special  commission  to  study  radio 
problems;  (2)  authorization  to  the  President  to 
designate  specific  hands  of  wavelengths  for  different 
classes  of  work;  (3)  a  Navy  monopoly  of  ship-to- 
shore  radio;  (4) 'a  Navy  monopoly  of  transocean 
and  international  radio;  (5)  authorization  to  use 
Navy  radio  stations  for  commercial  and  press  busi- 
ness; (6)  authorization  to  the  Navy  to  assist  Ameri- 
can enterprise  in  the  general  development  of  Ameri- 
can radio. -9  .   .   . 

This  article's  recital  of  the  discussions  between 
the  League's  emissary  (or  emissaries),  and  the 
Navy  Department  (at  Washington),  merits  ex- 
tensive quotation.  Note,  also,  that  the  late  Presi- 
dent Franklin  D.  Roosevelt  was  then  Asst. 
Secretary  of  the  Navy;  and  that  in  the  absence  of 
Secretary  Josephus  Daniels  (who  was  then  in 
Hawaii),  he  acted  as  one  of  several  spokesmen 
for  the  Department  in  these  talks. 

.  .  .  We  found  the  Navy  Department  surprised 
that  we  should  feel  any  alarm  over  the  proposed 
legislation,  as  they  point  out  that  no  mention  of 
amateurs  is  made  and  that  the  amateur  situation 
was  not  even  considered  by  them  in  this  matter. 
In  turn,  however,  we  have  been  obliged  to  point  out 
to  the  Navy  that  they  previously  attempted  to 
eliminate  us  and  that  the  resulting  skepticism, 
coupled  with  their  postponement  of  our  reopening 
August  1st  as  planned,  causes  the  amateur  to  regard 
with  distrust  any  move  on  their  part  to  get  control 
of  radio.  We  really  wanted  to  ask  what  assurances 


they  could  give  us  that,  if  they  secured  control  of  all 
radio,  the  stringency  of  restrictions  would  not  be 
increased  to  an  extent  resulting  in  our  virtual 
elimination;  but  the  legislation  is  not  yet  drawn 
up  and  we  found  the  gentlemen  wholly  in  sympathy 
with  the  cause  of  the  amateurs  and  desirous  of  dis- 
pelling the  distruct  with  which  we  have  been  regard- 
ing them.  We  told  them  we  desired  recognition  in 
their  contemplated  legislation;  i.e.,  rather  than  make 
no  mention  of  amateur  radio  and  leave  our  future 
to  the  discretion  of  some  individual,  we  wanted  our 
status  defined  in  the  new  bill.  The  Office  of  the 
Director  of  Naval  Communications,  which  is  han- 
dling the  matter,  then  invited  us  to  tender  our 
views  of  how  the  amateur  should  be  recognized  in 
the  new  law,  and  accordingly,  as  QST  goes  to  press, 
a  meeting  of  the  ARRL  Board  of  Directors  is  being 
called  to  formulate  our  ideas  for  presentation  to  the 
Navy  Department  and  it  is  probable  will  also 
arrange  to  have  us  represented  in  force  at  the  hear- 
ings of  the  bill,  to  make  sure  that  nothing  goes 
wrong,  and  that  nothing  inimical  to  our  interests  is 
contemplated  in  the  Navy's  request  for  "a  compre- 
hensive system  of  regulation  and  control "  to  achieve 
"the  full  utilization  of  radio  for  internal  communi- 
cation." 

We  are  surprised  to  find  no  apparent  connection 
between  the  postponement  of  our  reopening  on 
August  1st  and  the  simultaneous  request  of  the 
Navy  for  new  legislation.  They  deny  that  we  were 
held  up  to  enable  them  to  railroad  thru  a  bill  which 
would  endanger  us  before  their  control  automatically 
expires  with  a  declaration  of  peace.  But  the  sad  fact 
remains  that  we  are  not  opened,  and  no  information 
is  forthcoming  why.  Mr.  Daniels  is  in  Hawaii  and 
the  As.sistant  Secretary  of  the  Navy  stated  Mr. 
Daniels  personally  disapproved  the  opening  order 
and  that  he  (Mr.  Roosevelt)  did  not  know  why. 
.  .  .  We  pointed  out  to  Mr.  Roosevelt  the  bad  odor 
overhanging  the  whole  affair  and  the  extreme  de- 
sirability of  a  statement  by  the  Navy  explaining 
why  we  are  held  up  and  what  we  may  expect,  if  the 
suspicion  with  which  the  amateur  world  regards  the 
Navy  Department  is  to  be  eliminated.  Mr.  Roose- 
velt promised  to  immediately  radio  Mr.   Daniels, 


Canadian  .5BR,  at  Vancouver,  B.  C,  is  operating  a  half- 
kilowatt  transmitter  of  some  undisclosed  type  on  100 
meters  (Mumford's  report).  This  probably  was  a  spark  set, 
I  think. 

The  requirement  that  a  50-meter  wavelength  be  used 
during  the  navigation  season  is  referred  to  as  a  handicap 
in  an  editorial  at  29,  February  1921  (Volume  IV). 

Canadian  9AL  had  a  special  license  to  use  200  meters. 
See  38,  June  1921  (Volume  IV).  This  is  in  Russell's  report. 

In  Hertz's  report  (32,  April  1921,  Volume  IV),  it  is  stated 
that  the  synchronous  360-cycle  spark  transmitters,  found  on 
some  Canadian  ships  and  shore  stations,  and  used  at  one 
Canadian  amateur  station  (5PC),  might  do  well  on  short 
waves. 

At  34  to  35,  August  1921  (Volume  V),  Russell  declares: 
"The  short  wavelength  allowed  the  amateurs  near  routes  of 
navigation  makes  it  extremely  difficult  to  do  any  DX  work, 
although  certain  amateurs  (ex-commercial  operators),  have 
been  able  to  get  licenses  for  200  meters  for  all  the  year 
round.  .  .  ." 

The  new  April  1,  1922,  Canadian  regulations  allowed 
general  amateur  stations  to  use  spark  on  180,  and  c.w.  on 
200  meters.  Amateurs  with  special  station  licenses  were 
permitted  to  use  275  meters  on  c.w.,  and  200  on  spark.  (See 
Russell's  report,  at  46,  .June  1922,  in  Volume  V.) 

Canadian  3GN  (H.  R.  Byerlay,  of  Ingersoll,  Ont.)  oper- 
ated his  spark  transmitter  on  170  meters,  and  found  that 
this  was  disadvantageous,  because  few  receivers  could  tune 
down  that  low.  He  wanted  to  try  140-170  meters,  but  be- 
lieved the  receiver  situation  was  even  worse,  down  there. 
(See  his  letter,  at  02  to  03,  April  1922  Volume  V.) 


2*  At  17,  September  1919,  Entwistle  asked  amateurs  in 
northern  Maine  and  N.  H.  to  cooperate  with  Albert  J. 
Lorimer,  of  Montreal,  in  developing  some  trunklines  be- 
tween Canada  and  the  Northeastern  U.  S.  A. 

At  26,  March  1920,  J.  O.  Smith  said:".  .  .  The  managers 
of  the  Atlantic,  Central,  Rocky  Mountain  and  Pacific 
Divisions  report,  however,  that  considerable  traffic  is  now 
being  handled  across  the  border.  ..."  The  reports  cited 
don't  support  such  a  broad  statement.  Maybe  they  were 
cut  down  before  publication. 

Traffic  Manager  Smith,  at  26,  May  1920,  stated:  "... 
There  has  been  much  activity  among  Canadian  amateurs 
during  the  past  winter,  and  parts  of  Canada  not  heretofore 
represented  in  active  relay  work  have  become  closely 
connected  with  activities  in  the  states,  by  means  of  the 
trunk  lines  of  the  League,  which  have  been  extended  into 
Canada  with  such  excellent  results.  .  .  ." 

Russell's  report  for  the  Ontario  Division  (at  33,  June 
1920)  recites  that  "...  Permanent  daylight  communica- 
tion has  now  been  established  from  Toronto  to  Buffalo  via 
8ZM,  and  the  new  Niagara  Falls  station  should  also  be  in 
working  order  by  the  first  week  in  May.  .  .  ." 

Lorimer's  report  re  the  St.  Lawrence  Division,  at  45, 
June  1920,  says: 

"The  route  from  this  division  to  the  United  States  was 
opened  much  sooner  than  had  been  anticipated  and  is  now 
open  for  traffic. 

"The  attempt  to  work  direct  with  2SZ  at  Troy,  N.  Y., 
failed.  Normally  the  Albany  stations  are  QSA  here. 

"  We  have  been  advised  by  N.  P.  Mason  of  Platts- 
burg,  N.  Y.,  that  his  station  8BB  could  bring  our  route 


48 


QST  for 


and  wo  hope  to  know  soon  just  where  we  stand. 
Apparently  Mr.  Daniels  personally  is  responsible. 
The  whole  proposition  is  so  basically  unjust,  so 
uncalled  for,  that  we  do  not  believe  it  will  long  ob- 
tain.'o  .  .  . 

Further  news  on  the  legislative  "picture"  was 
given  in  another  editorial,  at  11  to  12,  October 
1919.  (This  one  was  entitled:  "Daniels  Only 
Knows.") 

The  ARRL  had  caused  a  Resolution  to  be 
introduced  in  Congress,  known  as  House  Resolu- 
tion 291.  This  had  requested  the  Secretary  of  the 
Navy,  "insofar  as  compatible  with  the  public 
safety,  to  furnish  reasons  why  the  restrictions 
[had]  not  been  removed."  This  document  had 
been  referred  to  the  House  Committee  on  the 
Merchant  Marine  and  Fisheries.  '^ 

After  reciting  these  facts,  the  editorial  then 
reported  that  on  August  28,  1919,  the  Navy  De- 
partment had  furnished  to  the  Senate  Committee 
on  Naval  Affairs  a  tentative  draft  of  its  new 
Radio  Bill  —  the  so-called  "Government- monop- 
oly" law. 

The  objections  of  the  amateurs  are  thus  stated: 

.  .  .  the  hit!,  thing  is  that  instead  of  providing 
regulations  for  wavelength,  power,  etc.,  this  bill 
would  provide  for  the  existence  of  a  technical  radio 

thru  New  York  State  to  Albany,  N.  Y.  A  quick  test  was 
arranged  from  2BF  (Can.)  and  communication  established 
with  8BB  with  little  trouble. 

"8BB  can  route  traffic  east  to  IVB  at  Hanover,  N.  H. 
and  south  to  2SZ  and  2BM.  As  soon  as  an  operating  scliedule 
can  be  arranged  we  will  be  able  to  handle  traffic  for  points 
in  Quebec. 

"District  Superintendent  Jarest  reports  considerable 
activity  in  the  vicinity  of  Levis,  with  new  stations  coming 
along  fast.  He  will  attempt  to  work  a  route  thru  to  Northern 
Maine  which  will  connect  with  the  Atlantic  route  north  of 
Boston.   ..." 

At  31,  June  1920,  Fray's  report  contains  the  following 
paragraph : 

"...  Mr.  Gjelhaug,  Dist.  Supt.  for  Northern  Minnesota, 
reports  that  he  has  been  testing  with  the  station  of  the 
Radio  Club  of  Winnipeg  and  expects  soon  to  have  a  route 
across  the  border  that  can  handle  traffic  regularly.  He  has 
had  some  correspondence  with  the  Winnipeg  Board  of 
Trade,  with  some  very  good  suggestions,  regarding  the 
status  of  radio  relay  work,  which  is  expected  to  speed  things 
up  in  that  direction." 
295,  September  1919. 

Just  what  "American  enterprise"  there  would  be  left,  to 
"assist,"  if  such  a  law  had  been  enacted,  I  don't  know. 

30  At  13,  August  1919,  an  editorial  called  "The  Lid" 
had  reported  the  collapse  of  an  expectation  that  the  ban  on 
transmitting  would  be  lifted  on  August  1,  1919.  The  Navy 
Department  had  stated  that  the  restriction  would  continue 
until  the  President  should  declare  that  a  state  of  peace 
existed. 

At  6,  September  1919,  it  is  said:  "...  Mr.  Roosevelt 
stated  we  would  be  released  'as  soon  as  Mr.  Daniels  would 
permit  it '  and  in  response  to  an  inquiry  addressed  by  a 
Senator,  wrote  that  '  the  Department  has  decided  to  remove 
the  war-time  restrictions  on  radio  coincident  with  the 
proclamation  of  peace  by  the  President.'  ..." 

3'  This  Resolution  was  not  effective.  However,  Hon. 
William  Stedman  Greene,  Chairman  of  the  House  Commit- 
tee on  The  Merchant  Marine  and  Fisheries,  later  prepared 
another  (and  similar)  Resolution  (H.  J.  Res.  217),  directing 
the  Secretary  of  the  Navy  to  remove  the  Amateur  restric- 
tions. This  evidently  caused  the  Navy  to  act.  See  "The 
Champion  of  the  Amateurs,"  at  5,  November  1919. 

32  This  was  not  the  last  to  be  heard  from  the  so-called 
"Poindexter  Bill,"  however.  See  5  to  6,  12,  December  1920

session  would  formulate  and  promulgate  regulations 
concerning  wavelength,  power,  decrement,  purity, 
operating  procedure,  etc.,  for  all  the  classes  of 
stations.  This  new  law  states  we  should  use  no 
wavelength  except  that  set  for  us  by  the  committee, 
and  then  leave  the  regulations  to  be  framed  from 
time  to  time  at  the  discretion  of  the  committee  in- 
stead of  being  definitely  set  forth  in  the  law.  This  is 
small  assurance  for  the  continuance  of  amateur 
radio,  with  our  destinies  entirely  in  the  hands  of  a 
government  committee  who  would  not  be  empow- 
ered even  to  hold  public  hearings  where  the  affected 
classes  of  stations  could  explain  their  cases.  .   .   .

OPERATING  THE  HEATHKIT  MODELS 
VF-1  AND  ATI  AT  21  MC. 

WITHOUT  modification  of  one  unit  or  the  other, 
the  VF-1  and  AT-1  will  not  operate  in  combi- 
nation at  21  Mc.  The  transmitter  was  designed 
for  Novice  use  with  crystal  control.  It  emj^loys  a 
5-Mc.  crystal  and  operates  VA'ith  the  oscillator 
plate  circuit  tuned  to  10.5  Mc.  when  output  at 
21  Mc.  is  desired.  In  designing  the  VFO,  however, 
it  was  desirable  to  produce  a  device  with  univer- 
sal application,  which  would  work  with  a  ma- 
joritj'  of  transmitters  and  use  a  minimum  number 
of  basic  oscillator  frequencies.  As  a  result,  the 
VF-1  was  designed  to  deliver  7-Mc.  output  and 
must  be  followed  by  a  frequency  tripler  if  21-Mc. 
excitation  or  output  is  to  be  made  available. 
It  is  in  this  way  that  the  incompatibility  (at 
21  Mc.)  of  the  two  units  developed.  Needless 
to  say,  the  next  model  revision  of  the  AT-1 
will  incorporate  changes  to  clear  up  the  matter. 

Those  who  own  Models  VF-1  and  AT-1 
may  make  a  simple  modification  to  the  trans- 
mitter which  permits  the  VFO  to  be  used  "as  is" 
for  e.xciting  the  rig  at  21  Mc.  The  change  con- 
sists of  adding  a  s.p.s.t.  wafer  switch  to  the 
plate  circuit  of  the  AT-1.  The  switch  is  used  to 
open  the  10.5-Mc.  tap  on  the  oscillator  plate 
coil  whenever  the  transmitter  bandswitch  is  set 
at  the  21-Mc.  position.  With  the  main  switch  so 
set,  and  with  the  new  switch  in  the  open  posi- 
tion, the  oscillator  tank  will  cover  the  7-Mc. 
range  necessary  for  tripling  into  the  21-Mc. 
band.  Naturally,  with  this  method  of  operation, 
the  7-Mc.  output  from  the  VFO  is  fed  straight 
through  the  oscillator  to  the  grid  of  the  6L6 
and  the  final  is  operated  as  a  tripler. 

The  new  switch  should  be  mounted  on  the 
front  panel  of  the  AT-1  to  the  lower  left  of  the 
meter.  This  places  the  wafer  of  the  switch  in 
front  (as  seen  from  the  rear  of  the  transmitter) 
of  the  oscillator  plate  coil.  In  rewiring  the  circuit, 
first  disconnect  the  lead  that  runs  to  terminal 
No.  2  (see  pictorial  No.  2  of  the  Heathkit  manual) 
at  the  top  of  the  oscillator  coil.  Now,  connect 
this  lead  to  the  rotor  contact  of  the  new  switch 
and  then  add  a  short  lead  between  the  stator 
contact  of  the  switch  and  terminal  No.  2  of  the 
coil.  In  other  words,  the  s.p.s.t.  wafer  is  wired  in 
series  with  the  1().5-Mc.  tap  for  the  oscillator 
inductor. 

Obviously,  this  extra  switch  does  not  represent 
the  "ideal"  in  convenience.  However,  for  those 
who  wish  to  operate  at  21  Mc,  it  is  a  far  more 
desirable  modifi(!ation  than  would  be  one  in- 
volving alterations  to  the  VFO  circuit.  Further- 
more, the  change  can  be  accomplished  without 
anj'    great    expense    or    difficulty    and    permits 


making   use   of   21-M(t.    ilial    caliljration    of   the 
VF-1. 

—  E.  B.  Mullings,  W4MKZ/8 

ALTHOUGH  the  popular  Heathkit  type  AT-1 
-  transmitter  works  properly  w^hen  using 
crystal  control,  it  will  not  perform  satisfactorily 
at  21  Mc.  when  used  in  conjunction  with  the 
Heathkit  model  VF-1  VFO.  The  reason  why  the 
two  units  do  not  work  together  at  this  frequency 
has  been  explained  by  W4MKZ/8  earlier  and 
need  not  be  repeated  here.  However,  the  method 
used  here  at  W9RQT  to  remedy  the  condition 
may  be  of  interest  to  those  who  do  not  wish  to 
drill  into  the  panel  of  their  AT-1.  The  operation 
requires  the  addition  of  a  single  padder  capacitor 
to  the  VFO  and  necessitates  absolutely  no  modi- 
fication to  the  transmitter.  It  does,  however, 
eliminate  the  11-meter  range  of  the  VF-1. 

With  the  original  VFO  circuit,  excitation  for 
the  11 -meter  operation  of  a  transmitter  is  ob- 
tained by  switching  in  a  padder  that  provides  a 
VFO  tuning  range  of  6740  to  6808  kc.  This 
particular  capacitor  is  the  4.5-  to  25-nni.  job 
shown  at  the  lower  left-hand  corner  of  the 
diagram  for  the  model  VF-1  (see  Heathkit 
manual).  By  increasing  the  effective  capaci- 
tance of  this  padder,  it  is  possible  to  obtain  a 
VFO  range  of  5250  to  5362  kc.  I  used  a  SO-mm^- 
silver  mica  as  the  new  padder,  but  there  is 
sufficient  space  available  for  the  installation  of  a 
variable  capacitor  if  the  lattei-  is  preferred. 

With  the  new  set-up,  the  VFO  unit  is  set  at 
the  old  11-meter  position  and  the  transmitter 
bandswitch  is  adjusted  to  the  normal  21-Mc. 
position  for  output  at  the  latter  frequency.  The 
5-Mc.  output  from  the  VFO  is  then  doubled 
in  the  AT-1  oscillator  plate  circuit  and  the  final 
of  the  transmitter  operates  as  a  doubler  as 
before. 

The  output  coil  for  the  VF-1  should  be  read- 
justed to  peak  the  output  at  the  new  tuning 
range  and  the  11-meter  scale  of  the  dial  can  be 
recalibrated  in  terms  of  21-Mc.  frequencies. 
Excellent  bandspread  —  nearly  180  degrees  of  the 
main  tuning  control  —  is  obtained  at  21  Mc. 
with  the  modification  completed.

GROUNDING  SHAFTS  OF 
VARIABLE  CAPACITORS 

1ACKING  other  means  of  grounding  ^-inch 
J  shafts  on  variable  capacitors,  a  small  Type 
8  grid  cap  (for  6J7s,  etc.)  slipped  over  the  shaft 
behind  the  panel,  and  tied  to  ground  with  a  sturdj' 
wire,  makes  a  very  effective  sliding  contact.

GROUND  AND  POLARITY  TESTER 

IN  the  interest  of  safety,  it  is  advisable  to 
test  all  leads  to  ground  (earth)  for  resistive 
characteristics.  A  resistive  circuit  or  lead  to 
ground  is  not  a  safe  one  and  may  not  be  depended 
on  as  a  means  of  preventing  accidental  shock. 

The  simple  circuit  shown  in  Fig.  1  may  be  as 
familiar  to  many  hams  as  it  is  new  to  others.

but  it  does  provide  one  of  the  (juickest  means  of 
checking  the  effectiveness  of  a  ground  lead.  An 
ordinary  lamp  bulb  of  almost  any  wattage  rating 
is  used  as  the  indicator  for  the  tester.  One  ter- 
minal of  the  bulb  is  connected  to  a  standard  115- 
volt  plug  and  the  second  terminal  of  the  lamp  is 
connected  to  a  heavy  clip  or  probe  which  in 
turn  is  used  to  make  contact  with  the  ground 
point  under  test.  The  i)ull)  will  light  to  full  bril- 
liancy when  connected  between  the  a.c.  line  and 
a  good  ground  point.  On  the  other  hand,  less 
than  normal  l)rilliancv  indicates  a  poor  ground 
connection. 

A  second  use  for  the  simple  circuit  is  that 
of  testing  for  either  tlie  hot  or  the  grounded 
side  of  the  a.c.  line.  The  bulb  will  light  when  the 
active  side  of  the  plug  makes  contact  with  the 
hot  side  of  the  a.c.  receptacle  and  will  fail  to 
glow  when  contact  is  made  with  the  grounded 
side  of  the  line. 

—  Joseph  A.  Wright,  jr.,  W.iUEB 

[Kditor's  Note:  Two  precautions  should  be  observed 
when  iisins  the  lamp-bulb  ground  tester.  When  testing 
the  effectiveness  of  a  lead,  make  sure  that  the  test  lamp  is 
lighted  to  full  brilliancy  by  cheeking  it  against  a  lamp  of 
similar  rating  that  has  been  plugged  into  a  convenient 
115-volt  socket.  Second,  when  attempting  to  determine  the 
|)olarity  of  an  a.c.  outlet,  make  sure  that  the  test  lamp  is  a 
good  one;  remember,  a  hurncd-oul  lamp  won't  glow  even  when 
connected  to  the  hot  side  of  the  line.] 

MODIFYING  COMMAND  TRANSMITTER 
RELAYS  FOR  6-VOLT  OPERATION 

WHEN  modifying  Command  transmitters,  many 
hams   discarded   the   seemingly   useless   an- 
tenna  relay  —  the   one   with  two  coils  and  no 
standard   contacts.    Fortunately,    I   saved   mine 
and  have  since  found  a  good  use  for  the  units. 
The  keying  relay  for  the  transmitter  is  ideally

suited  for  mobile  gear  because  of  its  compact 
size  and  pair  of  s.p.s.t.  contacts,  but  it  won't 
operate  on  6  volts.  However,  the  300-ohm  coil 
for  this  relay  can  be  easily  replaced  with  one  of 
the  90-ohm  coils  from  the  antenna  relay.  To 
complete  the  transfer,  it  is  necessary  to  reduce 
slightly  the  length  of  the  core  for  the  90-ohm 
winding,  and  this  job  can  be  quickly  done  with  a 
hack  saw  and  file.  Removal  and  relocation  of 
the  coils  is  a  simple  task  because  each  is  held 
in  place  with  a  single  flat-head  screw. 

The  modified  relay  (Fig.  2B)  really  works  on  6 
volts  and  draws  only  70  ma.  or  so  from  the 
battery.  And  the  compactness  involved  is  enough 
to  catch  the  eyes  of  any  mobile  fan.

SIMPLE  V.H.F.  R.F.  OUTPUT 
INDICATOR 

A\  inexpensive  trimmer  capacitor  and  an  oidi- 
-  nary  pilot  lamp,  wired  in  series  as  shown  in 
Fig.  3,  makes  a  useful  output  indicator  for  v.h.f.

common  indications  of  circuit  resonance  —  mini- 
mum plate  current  —  is  frequentlj-  difficult  to 
observe. 

The  indicator  may  be  permanentl}-  connected 
across  the  series-tuned  output  circuit  of  a  trans- 
mitter. A  3-30-A(Mf.  trimmer  and  a  60-ma.  bulb 
are  used  with  the  30-watt  rig  here  at  W2FFY. 
The  power  consumed  by  the  lamp,  about  a 
tenth  of  a  watt,  is  negligible.  By  adjusting  the 
trimmer  and  by  emplo.\'ing  lamps  of  various 
current  ratings,  the  indicator  circuit  can  be 
used  with  a  wide  range  of  power  levels. 

In  addition  to  providing  means  for  indicating 
maximum  power  output,  the  arrangement  pro- 
vides a  continuous  check  on  transmitter  per- 
formance. The  fact  that  the  indicator  is  p(^r- 
manentlj'  connected  across  the  output  circuit 
prevents  the  need  for  retuning  as  is  frequently 
the  case  when  plug-in  or  clip-on  indicators  are 
temporarih'  installed.

T.R.F.  FOR  S.S.B. 

49  Claude  Ave. 
DenviUe,  N.  J. 
Editor,  QST: 

I  had  an  interesting  experience  recently  which  made  me 
wonder  if  it  had  occurred  to  anyone  else. 

I  set  up  an  old  SW-3  receiver  (vintage  of  the  30s)  for  the 
first  time  in  manj-  years.  After  getting  it  into  proper  operat- 
ing condition,  I  was  checking  it  against  my  present  modern 
superhet  receiver  and  suddenly  decided  to  see  how  it  would 
perform  on  single-sideband  signals.  Quite  a  surprise!  It  per- 
formed remarkably  well  and  proved  in  some  respects  com- 
parable to  the  superhet. 

For  some  time  the  general  method  of  receiving  single- 
sideband  signals  on  a  modern  superhet  receiver  has  called 
for  the  a.v.e.  off,  the  beat  oscillator  on,  the  a.f.  gain  control 
up  and  the  r.f.  gain  control  varied  according  to  input  level; 
then  starts  the  job  of  carefully  tuning  the  b.f.o.  for  proper 
demodulation. 

Well,  the  old  t.r.f.  doesn't  have  a.v.c,  is  decently  selective 
in  its  c.w.  condition,  has  good  sensitivity  (controllable)  and 
readily  demodulates  single-sideband  signals.  It  has,  of 
course,  the  disadvantage  of  being  easily  overloaded  by  ex- 
cessively strong  signals.  However,  for  only  three  tubes  it 
proved  to  be  a  remarkably  usable  receiver. 

.  .  .  All  of  this  to  prove  that  a  receiver  designed  for 
conditions  approximately  twenty  years  ago  is  still  accept- 
able for  a  method  of  transmission  that  was  virtually  un- 
heard of  in  Hamdom  at  that  time.

INTERPLANETARY  TRAFFIC 

138  Cordova  St. 
Syracuse  5,  N.  Y. 
Editor,  QST: 

A  suggestion  to  the  traffic-handling  fraternity.  We  who 
deliver  overseas  messages  should  be  careful  of  the  abbrevia- 
tion MARS,  whether  by  telephone  or  in  writing. 

Recipients  of  overseas  messages  can  get  some  pretty  wild 
ideas  for  which  they  can  hardly  be  blamed.  Is  it  their  fault 
when  we  deliver  to  them  a  radiogram,  the  origin  of  which  is, 
for  example,  "Korea  via  MARS,"  particularly  when  the 
remainder  of  the  message  is  obviously  genuine? 

Unless  we  wish  to  perpetuate  the  general  impression  of 
ham  radio  as  being  a  "kid's  hobby"  by  adding  this  addi- 
tional Buck  Rogers  angle  of  " via  MARS,"  it  would 

be  better  when  delivering  overseas  radiograms  to  mention 
that  organization  by  its  full  name  or  punctuate  the  abbrevi- 
ation.

3434  74th  Ave.,  SE 
Mercer  Island,  Wash. 
Editor,  QST: 

I  don't  like  to  write  to  the  editor,  but  my  subject  hardly 
has  the  makings  for  an  article  for  QST,  so  guess  I  gotta  do 
it  this  way. 

Here's  the  deal:  Almost  without  fail  on  a  c.w.  contact 
(as  well  as  'phone)  names  are  exchanged.  Rigiit?  You  know 
—  ur  sigs  hr  are  RST  xxx;  name  hr  is  .  .  .  .,  etc.  That's 
fine  for  'phone  —  doesn't  take  any  longer  to  say  "Uncle" 
or  whatever,  than  to  say  "Ed"  or  sumpin.  But  .  .  .  I've 
pounded  brass  commercially,  in  the  Navy,  and  on  ham 
circuits  for  nearly  50  years  and  in  Navy  and  commercial 
work  any  "code"  man  who  bothered  witli  a  name  for  a 
designation  was  "out  of  this  world"  or  "sissy"  or  some- 
thing. No  respectable  code  operator  (including  railroad 
telegraphers.  Western  Union,  RCA,  Press  Wireless,  Mackay 
Radio,  etc.)  would  even  think  of  using  anything  but  a  sine  of 
two,  maybe  three,  and  occasionally  only  one  letter!  This,  of 


course,  was  bom  of  the  practice  of  pinning  down  tlie  com- 
mercial. Navy,  or  private  telegrapher  who  actually  re- 
ceipted for  the  message,  so  the  responsibility,  in  case  of 
error,  could  be  fixed.  You  know  .  .  .  dispatcher  sends  a 
train  order  and  FS  receipts  for  it  by  sending  .  .  _  .  ...  which 
(in  International  Morse)  is  his  "sine."  Or,  an  RCA  man 
in  New  York  sends  one  to  Stavanger,  Norway;  it's  receipted 
by  Gustave  somebody-or-other.  Does  he  spell  out  R  NR  1 
GUST  AVE?  Not  by  a  darned  sight  —  it's  R  GV  and  that's 
that! 

My  point  is,  let's  write  it  up  and  boost  it  along  in  QST  — 
c.w.  men  use  sines  of  two  or  three  letters.  (Max,  if  it  happens 
to  be  the  guy's  name,  is  also  a  good  sine) ;  'phone  men 
continue  using  names!  Take  a  name  like  mine  —  just  ain't 
no  abbreviation  worth  a  hoot,  so  I  spell  it  all  out,  H-O-W- 
A-R-D?  Not  me!  I've  been  using  YB  for  a  "sine"  for  bet-

How  about  it  —  sines  for  c.w.  men  —  names  for  'phone

On  the  issue  of  allowing  Technician  Class  holders  to 
operate  on  a  lower  band.  .   .  . 

The  question,  I  think,  is  not  one  of  which  to  allow  —  2 
or  6  meters  —  but  whether  to  allow  either!  Along  with 
quite  a  few  other  hams,  some  Technician  holders  like  my- 
self, I  do  not  want  lower  frequencies. 

There  are  quite  a  few  Novices  who  also  hold  Technician 
licenses  and  who  will  want  to  use  them  only  after  they  have 
failed  their  General  code  test.  They  are  mainly  the  ones  who 
want  these  extra  privileges  even  though  they  have  done 
nothing  to  deserve  them!  They  are  seeking  only  easy  oper- 
ating conditions. 

I  have  never  held  or  ever  will  hold  a  Novice  license.  My 
sole  purpose  in  amateur  radio  is  to  experiment  with  trans- 
mission on  high  frequencies,  which  I  thought  when  I  ob- 
tained it,  was  the  Technician's  purpose.  I  feel  that  any 
changes  in  its  privileges  would  defeat  this  well-founded 
idea!

IT'S  REALLY  SO

Editor,  QST: 

For  many  years  now  my  fellow  amateurs  and  I  have  been 
following  the  activities  of  the  "  Podunk  Hollow  Radio  Club  " 
as  duly  depicted  on  many  covers  of  your  excellent  journal, 
QST.  For  an  equal  number  of  years  I  have  been  wondering 
what  the  significance  of  said  organization  might  be.  Grant- 
ing the  obvious  fact  that  the  purpose  of  the  "  Podunk  Hol- 
low Club"  is  aptly  to  demonstrate  the  foibles  of  club  activi- 
ties, we  yet  wonder  about  the  selection  of  the  term  "  Podunk 
Hollow"  as  the  surreptitious  name  of  the  locale  from  which 
the  club  derives  its  members. 

Having  recently  completed  extensive  research  into  tiie 
subject  (quite  by  accident  —  began  and  completed  fifteen 
minutes  ago),  I  liave  discovered  the  real  significance  of  the 
term  "Podunk  Hollow,"  which  has  been  hidden  from  the 
members  of  the  League.  At  first,  one  might  suppose  the 
term  "  Podunk  "  to  be  employed  in  the  sense  meaning  coim- 
tryish,  small-townish,  or  hick.  However,  my  research  has 
disclosed  an  entirely  different  definition  of  the  term  —  or 
rather  the  full  term  "Podunk  Hollow." 

This  evening  (the  rig  being  out  of  commission),  I    pulled 
down  a  rather  archaic  volume  from  my  father's  bookcase,

Benjamin  S.  Hamilton,  W6VFT,  was  recipient 
of  the  1954  General  Electric  Edison  Amateur 
Radio  Award  at  a  ceremony  dinner  held  in  Wash- 
ington, D.  C,  on  February  lOtli. 


Congratulationri  are  extended  to  Benjamin  S.  Hamil- 
ton, ^  6VFr  {left),  by  FCDA  Chief  Val  Peterson  after 
the  Edison  Award  was  presented  to  him  by  J.  M.  Lang 
(center),  manager  of  the  GE  Tube  Department. 

\\GVFT,  who  resides  in  La  Mesa,  Calif.,  or- 
ganized a  top-notch  radio  network  in  San  Diego 
county  composed  of  an  active  200-man  civil 
defense  radio  system.  In  addition,  he  planned 
operational  activities,  wrote  equipment  speci- 
fications, and  laid  out  the  required  physical 
facilities.  Furthermore,  he  established  an  excel- 
lent communications  system  for  the  San  Diego 
Chapter  of  the  ARC.  Mr.  Hamilton  serv^es  as  a 
communications  officer  with  the  40th  Division 
National  Guard  and  is  also  an  ARRL  Section 
Emergency  Coordinator. 

Judges  for  the  award  were  former  Governor 
Val  Peterson  of  Nebraska,  FCDA  administrator; 
Honorable  E.  M.  Webster,  FCCommissioner;  E. 
Roland  Harriman,  president,  ARC:  and  ARRL 
President  Goodwin  L.  Dosland,  W0TSN. 

The  presentation  ceremony  was  held  at  the 
Ma>  flower  Hotel.  Principal  speaker  for  the  oc- 
casion was  Mr.  Peterson,  who  paid  this  tribute 
to  the  importance  of  amateur  communications: 
■'.  .  .  No  matter  how  effective  an  enemj- attack 
is,  it  can  never  destroj'  all  of  the  amateur  radio 
installations  —  the  120,000  of  them  —  and  that 
is  why  they  are  so  important  to  civil  defense  and 
to  the  nation.  ...  I  am  not  sure  but  what  the 
first  communications  in  the  first  few  hours  after 
an  attack  will  be  b\-  amateur  radio." 

A  special  citation  was  also  given  to  Carl  J. 
Theis,  W8BKH,  who  designs  and  builds  radio 
equipment  for  use  by  Baptist  missionaries  in 
Liberia.  Another  special  citation  went  to  Carter 
Rogers,  W8NCS,  who  operated  continuously  for 
16  hours  when  a  flash  flood  rendered  the  usual 
communications  facilities  of  Richwood,  W.  Va., 
inoperable.  In  addition,  800  amateurs  who  par- 
ticipated in  emergency  operations  during  Hurri- 
canes Carol,  Edna,  and  Hazel  were  issued  special 
certificates  of  recognition.

YL  Clubs 

Recent  years  have  seen  the  organization  of 
several  new  YL  clubs;  we  predict  the  formation 
of  many  new  ones  shortly.  This  month  we'd 
like  to  make  a  start  in  the  project  of  compiling 
information  about  the  various  existing  clubs 
which  are  on  record  with  us.  If  you  are  a  member 
of  a  YL  club  which  is  "organized"  —  i.e.,  has 
formal  name,  officers,  regular  meetings,  etc.  — 
and  j'our  cluli  does  not  appear  below  —  please 
mail  us  a  postcard  with  information  about  your

In  past  departments  we  have  already  de- 
scribed two  XYL  clubs  —  XYLs  of  members

are  no  longer  a  novelty.  But  when  father,  mother,  son, 
and  daughter  all  have  ham  tickets,  interfamily  compe-

pride  that  the  family  experiences  is  strong.  .So  it  is,  at 
least,  v»ith  the  ^  iley  family  of  Del  Paso  Heights,  Calif. 
Dad  is  Vt  6GKW,  mom  is  k6DPM,  and  son  and  daugh-

Rubie  and  12-year-old  daughter  Lorraine  took  their 
Novice  exams  at  the  same  time,  and  a  few  months  later 
passed  their  General  Class  exams. 

YL  contest  winning  fever  is  catching,  at  least  in  the 
Crane  family  of  Birmingham,  Ala.  C.w.  section  winner 
W4YYJ  will  place  her  cup  (received  from  last  year's  winner 
W4RLG)  alongside  that  of  her  OM,  W4ARR,  who  won  last

QST  an  International  Passport 

During  a  recent  trip  to  Spain,  \V2YCX,  Carolyn  (Carlie) 
Hull,  found  that  her  photograph  which  appeared  in  QST 
(this  department,  September.  1952)  was  her  passport  to  a 
wonderful  time  in  that  country.  Some  of  the  hams  she  met 
there  remembered  seeing  her  picture  and  consequently 
accepted  her  as  an  old  friend  in  real  ham  style. 

CaroljTi  recounts: 

Meeting  Spanish  amateurs  was  more  fun  to  me 
than  any  sightseeing.  One  day  I  entered  a  radio  store 
in  Madrid,  hoping  to  meet  a  Spanish  ham.  Words 
failed;  I  pulled  out  my  QSL  card.  The  salesman 


understood  and  telephoned  EA4BF,  Alberto  Kirsch- 
ner.  Alberto  spoke  fluent  English  and  through  long 
.subscription  to  QST  he  knew  much  about  ham 
radio  in  the  United  States.  Subsequently,  Alberto 
and  his  charming  family  in\-ited  me  to  a  gathering  of 
the  URE  or  Union  de  Radioaficionados  Espanulcs 
(Union  of  Spanish  Radio  Amateurs),  and  I  was  able 
to  learn  something  alwut  amateur  radio  in  Spain. 

The  URE  is  the  only  radio  club  in  that  country. 
EAs  are  handicapped  by  the  high  cost  of  good 
equipment  and  a  dearth  of  components.  The  legal 
maximum  power  input  is  only  50  watts.  These  fac- 
tors force  each  Spanish  ham  to  use  his  ingenuity  to 
the  limit.  He  must  be  a  technician  as  well  as  opera- 
tor, and  most  EAs  know  their  equipment  inside  out. 
By  the  judicious  use  of  antennas  and  good  operating 
conditions,  the  E.\  can  hold  his  own  with  anyone  in 
working  DX;  and  despite  operating  difficulties,  EAs 
are  typical  hams  and  have  the  true  ham  spirit. 

There  are  very  few  Spanish  YLs,  and  I  was  not 
only  the  sole  YL  at  the  meeting,  but  one  of  the  first 
American  YLs  ever  to  visit  them. 

A  reporter  for  Revista  de  Radio,  the  URE's  ama- 
teur organ,  asked  me  about  my  personal  amateur 
activities,  but  no  one  asked  me  much  about  amateur

RE  "LOW-IMPEDANCE 
TRANSMISSION  LINES" 

17  Random  Road 
Princeton,  N.  J. 
Technical  Editor,  QST: 

Under  "Technical  Correspondence"  (page  47)  in  the 
February,  1955,  issue  of  QST,  Lt.  John  J.  Dougherty  has  a 
letter  which  induces  me  to  make  certain  comments.  While 
it  may  be  true  that  particular  antenna  configurations  may 
have  influenced  some  people  who  were  responsible  for 
standardization  of  the  characteristic  impedance  of  trans- 
mission lines,  I  believe  the  evidence  indicates  that  the  choice 
was  made  on  a  much  more  sophisticated  engineering  basis. 
If  one  fi.\es  the  diameter  of  the  outer  conductor  of  a  trans- 
mission line,  it  can  be  shown  that  —  for  air  dielectric  —  the 
attenuation  will  be  a  minimum  when  the  characteristic 
impedance  is  about  77  ohms.  I  believe  this  accounts  for  the 
nominal  75-ohm  lines. 

The  standardization  on  50-ohm  lines  is  not  as  clear  cut. 
Prior  to  standardization,  flexible  lines  were  made  by  filling 
75-ohm  lines  with  suitable  dielectric  material.  As  at  present, 
these  had  a  dielectric  constant  of  the  order  of  2.25,  which 
made  the  lines  have  a  characteristic  impedance  near  50 
ohms.  The  development  of  radar  and  the  resulting  high  peak 
power  further  reopened  the  subject.  For  a  fixed  outer  con- 
ductor and  air-dielectric  line,  the  breakdown  voltage  for  a 
fixed  input  power  is  a  maximum  for  a  30-ohm  line.  From 
discussions  with  people  who  were  involved  at  the  time  the 
choice  was  made,  it  appears  that  50  ohms  was  selected  be- 
cause it  was  already  quite  widely  used  and  was  a  reasonable 
compromise  between  minimum  attenuation  and  maximum 
power  capability. 

Near  the  close  of  his  letter,  Lt.  Dougherty  makes  the 
statement  that  putting  transmission  lines  in  parallel  reduces 
the  transmission  line  losses.  This  is  incorrect  as  can  be 
shown  easily  using  Lt.  Dougherty's  example.  Suppose  a 
single  transmission  line  is  properly  terminated  by  a  load 
and  is  of  such  a  length  that  one  half  of  the  input  power  is 
lost  in  the  line.  Now  if  the  load  is  transformed  to  one  half 
the  original  value  and  two  identical  lines  in  parallel  are 
used,  the  lines  will  be  properly  terminated  and  one  half  the 
source  power  will  enter  each  line.  As  before,  one  half  the 
power  entering  each  line  will  be  lost  in  the  line.  Obviously, 
then,  each  line  will  absorb  one  fourth  of  the  source  power 
making  the  total  loss  one  half,  exactly  the  same  as  in  the 
case  of  the  single  line.  The  two-line  system  is  capable  of 
handling  twice  the  power  of  the  single  line  and  a  lower  im- 
pedance load  can  be  fed  without  additional  matching  means 
but  line  loss  is  unchanged. —  Wendell  C.  Morrison,  W2YCE 

[Editor's  Note:  Several  letters  have  been  received  ques- 
tioning the  validity  of  Lt.  Dougherty's  statements  about 
coaxial  lines  in  "series"  and  in  "parallel."  The  accompany- 
ing sketch  may  help  to  explain  them  further.  It  should  be

obvious  that  the  s.w.r.  on  the  sections  of  lines  will  be  1.0 
in  each  case,  but  the  terminating  loads  are  respectively 
twice  and  half  the  Zo  of  the  pieces  of  line.] 

MODULATION  TRANSFORMERS 

iSan  Bruno,  Calif. 
Technical  Editor,  C'.ST'.- 

In  plate-modulated  Class  C  r.f.  amplifier  service  such  as 
we  have  in  a.m.  voice  applications,  tliere  has  been  needless 
confusion  about  the  choice  of  the  proper  modulation  trans- 
former. As  long  as  the  transformer  is  big  enough  to  handle 


the  power,  and  as  long  as  we  don't  ask  it  to  worK  into  too 
high  an  impedance  on  its  secondary,  the  only  thing  we  have 
to  worry  about  is  obtaining  the  proper  voltage  transforma- 
tion to  make  tlie  audio  and  Class  C  tubes  work  correctly. 

At  the  100  per  cent  modulation  level  the  peak  value  of 
the  audio  voltage  out  of  the  transformer  should  be  just  equal 
to  the  d.c.  value  of  the  plate  voltage  applied  to  the  Class  C 
stage.  Similarly,  at  100  per  cent  modulation  we  know  that 
the  peak  value  of  the  audio  current  component  is  also  just 
equal  to  the  d.c.  plate  current  of  the  Class  C  stage.  This 
current  relation  follows  directly  from  the  fact  that  the  Class 
C  amplifier  plate  circuit  presents  the  same  impedance  to 
the  audio  source  as  it  does  to  the  d.c.  power  supply.  That  is 
why  we  calculate  this  impedance  by  dividing  the  d.c.  plate 
voltage  by  the  d.c.  plate  current. 

Now  that  we  know  the  peak  audio  voltage  wants  to  be 
just  equal  to  the  d.c.  plate  voltage  at  100  per  cent  modula- 
tion, we  can  start  asking  what  the  modulation  transformer 
does.  Basically,  it  must  develop  this  desired  output  voltage 
when  the  primary  of  the  transformer  has  the  proper  voltage 
present.  This  is  the  point  where  the  audio  modulator  stage 
gets  into  the  act.  In  order  for  the  audio  modulator  tubes  to 
work  properly,  the  audio  voltage  built  up  in  each  plate  cir- 
cuit should  be  on  the  order  of  70  per  cent  to  80  per  cent  of 
the  applied  d.c.  plate  voltage  at  the  maximum  signal  level. 
Each  half  of  the  primary  of  the  transformer  must  develop 
this  audio  peak  voltage  since  each  half  has  a  separate  tube 
across  it. 

Now  if  we  happen  to  use  the  same  d.c.  plate  voltage  on 
the  modulator  (or  audio  amplifier)  as  we  do  on  the  Class 
C  r.f.  stage,  the  peak  audio  voltage  at  100  per  cent  modula- 
tion which  is  developed  in  each  half  of  the  primary  of  the 
transformer  is  70  per  cent  to  80  per  cent  of  the  d.c.  plate 
voltage  involved,  and  of  the  peak  audio  voltage  developed 
in  the  secondary  of  the  transformer  (since  the  latter  is  equal 
to  the  d.c.  plate  voltage).  This  says  that  the  number  of 
turns  in  one-half  the  primary  of  the  transformer  must  be  70 
per  cent  to  80  per  cent  of  the  number  of  turns  in  the  secondary. 
The  number  of  turns  in  the  full  primary  of  the  transformer 
is  twice  this,  or  140  per  cent  to  160  per  cent  of  the  number 
of  turns  in  the  secondary.  This  is  often  stated  as  a  primary 
to  secondary  turns  ratio  of  1.4  or  1.6  to  one.  Thus  the  modu- 
lation transformer  is  fully  specified  provided  it  is  big  enough 
to  handle  the  power. 

Note  that  the  modulation  transformer  was  chosen  without 
mentioning  the  value  of  d.c.  plate  current  drawn  by  the 
Class  C  stage,  or  the  amount  of  plate  current  drawn  by  the 
audio  amplifier.  Also  note  that  nothing  was  said  about  the 
exact  impedance  placed  on  the  secondary  of  the  transformer 
or  about  the  impedance  which  must  be  presented  to  the 
audio  amplifier.  The  fact  that  the  current  drawn  by  the 
amplifier  and  the  load  impedance  are  not  involved  in  the 
choice  of  the  modulation  transformer  is  demonstrated  daily 
in  the  operation  of  Class  C  amphfiers.  Once  a  proper  modu- 
lation transformer  has  been  chosen  we  change  the  load  on 
our  Class  C  amplifier  freely  without  in  any  way  disturbing 
our  ability  to  modulate  well  and  with  good  quality. 

The  impedance  presented  to  the  secondary  of  tlie  modu- 
lation transformer  (or  the  voltage  to  current  ratio)  is  de- 
I^endent  upon  and  will  vary  with  the  amount  of  d.c.  plate 
current  drawn  by  the  Class  C  stage.  Because  the  transformer 
transforms  this  impedance  to  the  primary  side  by  the  square 
of  the  turns  ratio,  the  primary  impedance  will  also  vary.  It 
should  be  noted,  however,  that  the  voltage  transformation 
is  not  upset  by  the  way  in  which  we  vary  the  loading  on  the 
secondary  of  the  transformer.  This  is  the  familiar  behavior 
of  60-cycle  power  transformers. 

For  audio  amplifiers  used  as  modulators  we  don't  have  to 
concern  ourselves  about  the  particular  value  of  load  im- 
pedance which  is  listed  on  the  tube  data  sheet.  As  long  as 
the  tubes  are  capable  of  supplying  the  desired  output  power, 
and  as  long  as  the  modulation  transformer  has  the  right 
voltage  ratio,  the  tubes  will  work  efficiently  and  satisfac- 
torily. As  indicated  above,  an  audio  modulator  works  effi- 
ciently when  the  peak  audio  voltage  in  its  plate  circuit  is 
some  70  per  cent  to  80  per  cent  of  the  d.c.  plate  voltage  at 
maximum  signal.  In  Class  ABi  modulators  the  peak  audio 
voltage  is  somewhat  smaller  and  may  be  nearer  a  60  per 
cent  figure.—  W.  G.  Wagener,  W6VQD

QST  for 


1955  V.H.F.  Sweepstakes 

8th  Annual  Winter  Contest  Activity  at  Ail-Time  High 


IN  1951,  the  low  point  in  the  history  of  the 
Annual  V.H.F.  Sweepstakes,  299  logs  were 
sent  in.  Since  then,  the  curve  has  shown  a 
constant  upswing:  365  in  1952,  385  in  1953,  610 
in  1954.  In  the  8th  running,  January  8  and  9, 
1955,  the  total  climbed  to  747,  and  this  does  not 
include  a  handful  received  after  the  mailing 
deadline.  In  just  about  any  other  category  you 
can  name,  the  1955  V.H.F.  SS  was  also  a  record- 
breaker. 

Significantly,  this  came  about  under  strictly 
normal  conditions.  Not  a  contestant  reported 
any  real  break  from  conditions,  yet  in  the  more 
densely  populated  areas  the  contest  ran  hot  right 
up  through  the  last  minute  before  midnight 
Sunday.  Where  heretofore  more  than  200  con- 
tacts by  any  one  contestant  has  been  a  distinct 
rarity,  no  less  than  15  made  or  e.xceeded  the  200 
mark  this  year,  and  quite  a  few  of  them  turned 
the  trick  with  just  one  band,  2  meters.  W3IBH 
was  the  country's  top  man  from  the  standpoint  of 
contacts  on  one  band,  with  245  on  144  Mc,  but 
it  took  W2UK's  unheard-of  section  multiplier 
of  18  to  post  the  country's  top  score.  Tommy 
worked  176  stations  for  6336  points,  far  exceed- 
ing the  record  of  4104  set  by  W2SAI,  way  back 
in  1950.  And  W2UK  made  them  all  on  144  Mc, 
and  with  the  band  dead!  K2CMB's  248  contacts 
on  144  and  220  was  the  top  in  QSOs  on  more  than 
one  band. 

How  far  the  1955  contest  exceeded  previous 
marks  can  be  seen  from  the  fact  that  nine  con- 
testants broke  the  old  W2SAI  record.  As  might 
be  expected,  most  of  these  were  in  that  hott)ed 
of  v.h.f.  activity,  the  stretch  of  heavily-popu- 
lated country  between  New  York  and  Phila- 
delphia, but  not  all  the  big  scores  were  made 
there,  by  any  means.  WlUIZ/1,  who  had  the 
temerity  to  take  to  the  site  used  so  successfully 
in  past  warm-weather  contests  by  WlMHL/l 
(Pack  Monadnock  Mountain,  near  Peterboro, 
N.  H.)  made  216  contacts  in  13  sections,  for  5603 
points,  and  the  No.  3  spot  nationally.  WIRFU, 
who  lives  on  his  mountain,  in  Wilbraham,  Mass., 
landed  in  No.  2,  with  218  contacts  in  13  sections, 
for  5668.  W6WSQ  showed  what  can  be  done 
from  the  Los  Angeles  area,  with  210  contacts  on 
144  Mc.  alone.  The  lower  section  multipliers  that 
prevail  outside  the  small-section  East  kept  his 
score  out  of  the  top  ten,  but  his  2100  points  be- 
longs right  up  there  with  the  best  of  them.  The 
same  goes  for  W8SVI,  Fairborn,  Ohio,  who  led 
all  the  inlanders  with  146  contacts  in  7  sections, 
for  2044  points. 

Novices  and  Technicians  were  out  in  force, 
and  there  were  15  certificate  winners  in  the 
newcomer  categories.  Novices  won  over-all  sec- 
tion awards  in  Eastern  New  York  and  Indiana, 
and   KN6GMV   must   have   set   some   kind   of 


Novice  record  with  163  contacts  on  2  meters  in 
the  Los  Angeles  Section. 

Unlike  the  spring  and  fall  contests,  the  SS 
doesn't  give  extra  credit  for  use  of  higher  bands 
than  144  Mc,  but  31  contestants  worked  on  220 
Mc.  and  14  used  420.  W6MMU  managed  several 
contacts  on  1215,  and  W7JIP  and  W70KV  put 
their  10,000-Mc.  gear  to  work  for  the  party. 
W7AXS  says  that  the  first  220-Mc.  work  in  the 
Seattle  area  came  off  during  the  contest. 

It's  the  club  incentive  that  makes  the  V.H.F. 
Sweepstakes  what  it  is,  the  fourth-ranking  ARRL 
operating  activity,  and  the  club  activity  was 
terrific  in  this  year's  event.  It  was  a  contest  be- 
tween two  Philadelphia-area  clubs,  as  often 
before,  but  combinations  from  other  areas  are 
gaining  ground  on  the  perennial  leaders.  The 
South  Jersey  Radio  Association  won  another 
gavel  award,  with  the  first  aggregate  of  more  than 
5t),00()  points  in  the  history  of  V.H.F.  SS  compe- 
tition, leaving  their  rivals,  the  York  Road  Radio

CONDUCTED  BY  EDWARD  P.  TILTON,  WIHDQ 


Is  that  new  beam  up?  Rig  free  of  bugs?  Con- 
verter in  apple-pie  order?  Better  get  set,  for 
there's  a  big  season  coming  up.  The  more  than 
750  logs  received  following  the  8th  V.H.F.  Sweep- 
stakes show  that  activity  is  developing  as  never 
before.  Auroral  DX  in  January  was  the  best  in 
years.  There  were  fine  tropospheric  openings  in 
February.  Winter  sporadic-E'  was  more  wide- 
spread and  it  lasted  longer  than  in  any  corre- 
sponding period  for  at  least  five  years.  Yes,  all  the 
signs  are  pointing  to  a  spring  DX  season  you 
won't  want  to  miss.  It  should  be  breaking  out 
most  any  time,  now.  Will  you  be  ready  for  it? 

The  activity  picture  on  144  Mc.  and  higher 
bands  is  bright,  indeed,  but  we  could  use  several 
hundred  new  stations  on  50  Mc.  There  were  too 
few  6-meter  men  on  hand  to  make  the  winter 
sporadic-j&  openings  show  to  good  advantage. 
The  winter  period  is  usually  over  shortly  after 
New  Year's  Da.y,  but  widespread  openings  were 
reported  through  the  end  of  January,  and  into 
February  in  1955.  On  January  29th,  for  instance, 
W6BWG,  San  Gabriel,  Calif.,  found  the  band 
open  at  1 555  PST,  and  was  able  to  work  W7D YD, 
Bothell,  Wash.,  W5MJD,  Amarillo,  Texas, 
W0CNM  and  W0FKY,  Grand  Junction,  Colo., 
W5KWP,  Santa  Fe,  N.  Mex.,  and  W5SIN, 
Pampa,  Texas,  in  43^  hours.  W5FXN,  Austin, 
Texas,  reports  an  S9-plus  signal  from  W7QN0, 
Phoenix,  Ariz.,  who  was  running  only  3  watts, 
and  using  a  2-element  array. 

TV  DX  enthusiasts  all  over  the  country  had  a 
four-day  DX  binge  beginning  the  29th.  If 
sporadic-£'  DX  shows  on  Channels  2  through  6, 
50  Mc.  is  open  over  the  same,  or  slightly  shorter, 


paths.  The  hundreds  of  TY  DX  hounds  have 
shown  us  one  thing  for  sure:  There  is  a  lot  more 
sporadic-^'  DX  than  6-meter  men  have  ever 
realized,  even  in  the  heyday  of  activity  on  the 
band  some  years  back. 

Newcomers  may  not  realize  how  much  fun  50- 
Mc.  sporadic-^^  DX  can  be,  nor  have  much  of  an 
idea  of  when  and  how  it  can  be  worked.  As  a 
result,  we  find  nearly  all  the  new  v.h.f.  activity 
on  144  Mc.  and  higher  frequencies,  with  50  Mc. 
getting  very  little  play  from  the  new  recruits.  So, 
for  them,  we  pass  along  a  little  dope  on  6-meter 
possibilities.  If  you're  an  old  hand  at  the  6-meter 
game,  skip  over  to  the  fine  print;  there'll  be 
nothing  in  the  next  few  paragraphs  that  will  be 
news  to  you. 

By  the  time  this  appears  in  print,  there  will  be 
just  about  time  for  you  to  get  6-meter  gear  going, 
and  an  antenna  up,  before  the  spring  DX  season 
gets  under  way  in  earnest.  Usually  the  best 
months  are  May,  June  and  July,  but  we've  had 
some  good  openings  as  early  as  the  latter  part  of 
March,  and  we  can  remember  hearing  West 
Coast  stations  in  the  latter  part  of  April  some 
years  ago.  The  best  signals  are  usually  heard  at 
distances  of  600  to  1200  miles,  but  at  the  peak  of 
the  season  (June  and  Jul.y)  the  skip  may  get  as 
short  as  300  miles,  or  even  less.  Multiple-hop 
propagation  brings  in  stations  at  greater  dis- 
tances, too,  making  50-Mc.  WAS  a  definite  possi- 
bility, from  anj'  point  in  the  country. 

DX  of  this  sort  shows  most  frequentlj'  in  the 
early  evening  hours,  and  thus  quite  a  few  chances 
are  missed  by  fellows  who  tend  to  operate  only 
late  at  night.  The  morning  hours  are  also  good, 


V.H.F.  Sweepstakesexpedition  up 
to  Capitol  Peak,  near  Olympia, 
Wash.,  by  members  of  the  Capitol 
City  Radio  Club.  The  sled  is  loaded 
with  a  1500-watt  generator,  gas 
cans,  food,  blankets,  a  6-eIement 
beam  and  two  Communicators. 
Hikers  include  W7s  POP  RKS 
PVZ,  WN7s  WGG  VXR  YCN  and 
two  others  whose  calls  are  on  the 
way.

with  midafternoon  generally  a  low  i)oint.  At  the 
start  of  the  season,  openings  are  frequently  short 
and  widely  scattered,  affecting  only  small  areas 
at  any  one  time,  but  from  late  May  through 
July,  sessions  may  last  for  several  hours,  and 
bring  in  just  about  every  section  of  the  country. 
Look  for  skip  to  open  to  the  east  first,  then  swing 
around  to  north-south,  with  finally  to  the  west 
before  a  good  opening  dies  out.  We  recall  com- 
paring notes  one  morning  after  a  tremendous 
June  splurge,  to  find  that  among  three  of  us  who 
had  been  on  the  night  before,  37  different  states 
had  been  heard  or  worked! 

The  beauty  of  it  all  is  that  it  doesn't  take  high 
power  or  large  antennas  to  work  the  skip  when 
conditions  are  good.  S9-plus  reports  are  common 
with  just  a  few  watts,  though  of  course  the  high- 
power  man  is  able  to  get  in  a  little  sooner,  and 
stay  a  bit  longer,  than  his  flea-powered  brother. 
Ten-watt  mobiles  with  cjuarter-wave  whips  can 
work  the  DX,  and  the  folded-dipole  operator  is 
likelj^  to  do  almost  as  well  as  the  big-beam  man, 
when  things  are  at  their  best.  Of  the  10  hams  who 
have  qualified  for  the  special  50-Mc.  WAS  award 
offered  by  ARRL,  not  one  used  a  kilowatt  rig. 
They  did  have  perseverance,  however,  and  some 
knowledge  of  when  and  where  to  look  for  their 
quarry. 

Probably  all  of  them  would  agree  that,  in  mak- 


ing those  48  contacts,  and  hundreds  of  others  be- 
fore and  since,  they  had  as  much  fun  as  in  any- 
thing they've  ever  done  in  ham  radio.  Chances 
are  you'll  feel  the  same  way  about  6  when  you've 
given  it  a  whirl.  There  will  never  Ix'  a  better  time 
to  get  starteil  than  right  now! 

Here  and  There  on  the  V.H.F.  Bands 

Not  all  the  tropospheric  DX  is  worked  in  the  summer  or 
early  fall.  The  weatherman  cooked  up  a  coastal  inversion 
along  the  Atlantic  Seaboard  on  the  night  of  Feb.  21st  that 
was  almost  equal  to  tlie  best  that  September  could  produce. 
It  was  made  to  seem  all  the  more  exceptional  by  the  pres- 
ence on  144  Mc.  of  WIDEO,  Cape  Elizabeth,  Maine,  who 
gave  2-meter  men  their  first  contacts  with  that  hard-to-get 
state  for  hours  on  end. 

Maine  has  probably  been  the  most  difficult  of  the  New 
England  states  for  operators  down  the  coast  in  W2,  3  and  4. 
It  is  farthest  awaj',  and  there  has  been  little  consistent 
activity,  with  horizontal  polarization,  and  the  necessary 
power,  receiver  sensitivity  and  antenna  gain  to  do  the  job  at 
that  distance.  If  WIDEO  keeps  up  at  his  present  pace,  there 
should  be  some  considerable  change  in  the  states-worked 
standings  before  long.  His  best  DX  on  the  2l8t  was  W4.\0, 
Falls  Church,  Va.,  about  500  miles.  This  was  No.  23  for 
\V4.\0. 

There's  life  in  the  6-meter  band.  \V0HVW,  Pleasant  Hill, 
Mo.,  managed  to  work  31  states  during  1954,  and  he  heard 
three  others,  including  Nebraska,  which  is  one  of  two  he 
needs  for  oO-Mc.  WAS.  Gib  says  that  W03  PYK  TOQ 
CKQ  and  QXT  will  be  on  6  this  summer,  to  help  him  keep 
Missouri  on  the  6- meter  map. 

Southern  New  Jersey  lost  one  of  its  most  active  v.h.f. 
sta'ions,  and  the  420-Mc.  band  one  of  its  strongest  boosters, 
when  W2QED,  Seabrook,  N.  J.,  closed  down  for  good  in 
February.  Ken  had  been  active  on  50.  144,  220  and  420 
Mc  for  more  than  two  years,  and  had  been  a  potent  factor 
in  tlie  420-Mc.  picture  along  the  .\tlantic  Seaboard  for  years 
before  tliat.  He  was  coholder,  with  W8BFQ,  of  the  420-Mc. 
record,  360  miles,  for  a  short  time  in  the  summer  of  1953, 
and  it  was  through  his  efforts  that  the  eastern  end  of  the 
record  was  passed  on  to  the  next  holder. 

W2QED  never  missed  a  v.h.f.  contest,  and  he  kept  regu- 
lar morning  and  evening  schedules  with  scores  of  stations, 
and  on  several  bands.  One  of  these  was  an  all-time  record  for 
your  conductor,  a  morning  check  on  144  (and  occasionally 
up  to  three  other  bands)  daily,  that  ran  for  nearly  four 
years,  and  close  to  1000  contacts. 

Stations  for  hundreds  of  miles  in  all  directions  from  Sea- 
brook,  N.  J.,  will  miss  W2QED.  But  the  East's  loss  is  the 
West's  gain,  for  we  understand  that  Ken  is  bound  for  the 
Los  .\ngeles  area,  where  he  will  find  plenty  of  opportunity 
to  continue  his  fine  work  in  the  world  above  50  Mc. 

Two  other  famous  stations  are  reported  to  be  on  the  verge 
of  dismantling  for  major  moves.  W2UK  will  be  closing  down 
in  a  few  months,  and  W8BFQ-WJC  is  reported  to  be  moving 
southward.  It  will  take  a  lot  of  operating  and  antenna  work 
to  fill  the  gaps  left  in  the  v.h.f.  bands  by  the  departure  of 
these  stalwarts! 

.\notlier  well-known  call  about  to  be  heard  in  a  new  local- 
ity is  VE3ANY.  Gordon  has  taken  up  permanent  residence 
in  the  Detroit  area,  and  will  soon  be  heard  on  the  v.h.f. 
bands  operating  under  his  old  call  with  a  reciprocal  permit 
from  FCC.  * 

V.h.f.  operators  of  the  Houston  area  have  formed  the  144 
and  Up  Club,  for  the  purpose  of  promoting  activity  and 
interest  in  v.h.f.  work.  This  grew  out  of  a  V.H.F.  Round-up 
held  last  fall.  Quarterly  contests  are  planned,  the  first  to 
begin  April  1st.  The  next  meeting  of  the  group  is  planned 
for  the  West  Gulf  Division  ARRL  Convention,  to  be  held 
in  Ft.  Worth,  June  10th  to  12th. 

We  have  notes  from  several  groups  and  individuals  this 
month  who  make  the  same  plea:  " Please  let  the  gang  know 
that  we  are  on  the  air  here,  and  ask  them  to  turn  their 
beams  in  our  direction  once  in  a  while."  K4AMX,  Winston- 
Salem,  N.  C.  (formerly  WIACG,  Lexington,  Mass.),  says 
that  he  works  W4NHW  in  Greensboro  and  W4CVQ, 
Raleigh,  N.  C,  almost  nightly,  but  would  like  to  hear 
from  other  stations  to  the  north,  west  and  south.  The 
Winston-Salem  CD.  Net  operates  on  147.15  Mc.  each 
Tuesday  and  Thursday  night  at  2000  with  W4CPI  as  con- 
trol station.

VE6HY  writes  on  behalf  of  the  Calgary  Amateur  Radio 
Association  that  tliere  are  about  15  stations  on  147.6  Mc.  in 
that  area.  They  would  like  to  hear  from  W7s  who  may  be 
within  operating  range. 

The  Davidson  County  (middle  Tennessee)  2-Meter  Net 
meets  Monday  and  Thilrsday  at  1930  CST,  with  \V40EZ, 
Nashville,  as  NCS.  .Alternate  is  W4TPIT.  .Average  number 
checking  in  is  about  10.  Vertical  polarization  is  u.«ed  in  net 
activities. 

KGCJKX.  Long  Beach,  Calif.,  writes  that  Thursday  and 
Friday  nights  are  set  aside  for  round-tables  on  220  and  420 
Mc.  Use  of  both  bands  is  on  tlie  increase,  with  W6s  SSB  ZW 
OCU  and  NIT,  particularly,  deserving  credit  for  their 
efforts  in  popularizing  these  bands. 

Anyone  for  220  Mc.  around  Williamsburg,  Va.?  W8LTE/4 
has  been  oi)erating  on  220.1  Mc.  with  a  converted  ARC-.5, 
but  has  found  nobody  to  talk  to  as  yet  A  4X150A  with 
changeable  tank  circuits  for  220  and  420  is  in  the  works. 

Have  you  heard  any  single  sideband  on  144  Mc?  Else- 
where we  report  that  W7JRG  has  finally  given  up  on  s.s.b. 
on  50  Mc,  because  so  few  fellows  recognize  it  when  6  is 
open,  but  W2JJC,  New  Market,  N.  ,J.,  has  been  doing  quite 
well  with  s.s.b.  on  144  Mc.  His  power  level  is  now  about  100 
watts  output,  from  a  pair  of  826s,  running  in  the  AB2  region. 
W2JJC's  best  DX  so  far  is  WIRFU,  and  very  nice  reports 
are  being  received  from  distances  up  to  100  miles  or  so  in 
other  directions.  As  almost  everyone  uses  a  crystal-con- 
trolled converter  on  144  Mc,  there  is  no  stability  problem 
in  receiving  the  2-meter  s.s.b.,  and  quite  a  few  listeners  have 
reported  the  readability  holding  up  remarkably  well  under 
conditions  when  a.m.  signals  are  fading  into  the  noise.  A  few 
checks  your  conductor  has  made  with  W2JJC  indicate  that 
the  readability  is  considerably  better  than  a.m.  of  com- 
parable power  level.  Watch  for  W2JJC  on  144.39  Mc 

Should  there  be  an  exclusive  cw.  assignment  in  the 
144-Mc.  band?  Quite  a  few  fellows  think  so,  and  at  least  one 
has  petitioned  FCC  to  set  aside  a  segment  at  the  low  edge  of 
the  band  for  cw.  operation  only.  There  are  several  good 
arguments  in  favor  of  such  a  move,  and  probably  few 
against  it,  though  talk  of  such  things  invariably  stirs  up  a 
hornet's  nest.  With  the  amount  of  activity  now  heard  in 
many  areas,  the  QRM  problem  is  getting  fairly  severe  on  2, 
particularly  at  the  low  edge.  It  takes  only  a  few  strong 
'phone  signals  to  fill  the  first  100  or  200  kc,  to  the  point 
where  any  DX  signal  is  well-nigh  obliterated.  Proponents 
of  the  cw.  assignment  idea  say  that  moving  up  100  or  200 
kc.  would  work  no  hardship  on  any  voice  operator  (we  all 
have  crystals  for  higher  in  the  band,  but  we  have  dropped 
using  them  in  most  cases)  but  it  would  help  to  free  a  lot  of 
territory  for  weak-signal  DX  operation,  and  make  it  easier 
for  everyone. 

Perhaps  the  alternative  to  legislation  would  be  for  us  to 
do  our  rag-chewing  above  144.2  Mc,  by  mutual  agreement, 
and  leave  the  low  edge  for  cw  DX  work  and  special  skeds. 
Anyone  can  QSY  200  to  500  kc,  usually  without  any  re- 
tuning.  Let's  do  it  more  often,  and  give  everyone  a  better 
break. 

Remember,  please,  that  the  way  to  get  ARRL  action  for 
or  against  a  proposal  that  involves  regulation  changes  is  to 
work  through  your  director,  not  through  the  Headquarters 
office.  We'll  be  glad  to  hear  opinions,  but  your  ARRL 
director  is  the  only  man  who  can  do  anything  about  the 
matter.  Be  sure  that  he  knows  how  you  feel. 

Corrections,  September  V.H.F. 
Party  Report 

Following  publication  of  the  results  of  the  September 
V.H.F.  Party  in  January  QST,  we  heard  from  several 
contestants  whose  work  was  improperly  reported,  or 
skipped  entirely.  Two  Iowa  logs  never  showed  up  at  all, 
and  both  of  them  were  the  best  that  the  participants  had 
ever  sent  in.  So,  belatedly,  we  announce  that  W0GUD  was 
top  man  in  that  section,  with  78  contacts  in  11  sections,  for 
858  points.  W0EMS  ran  him  a  close  second.  And  we  did 
W7RT  wrong  in  crediting  him  with  exactly  half  his  score. 
His  multiplier  was  4  instead  of  2,  bringing  his  total  to  212, 
and  moving  him  to  third  place  in  the  Washington  Section. 

OES  Notes

and  420  Mc.  back  up  after  heavy  damage  in  last  fall's  hurri- 
canes. Results  in  V.H.F.  SS  best  on  record.  Note  to  those

needing  Rhode  Island  QSLs:  WlKCS  now  has  stock,  and 
will  supply  to  all  stations  worked,  upon  receipt  of  QSL  or 
note  giving  date  of  contact. 

W2UTH,  Victor,  N.  Y.  —  144-Mc.  signal  of  WIHDQ,  260 
miles,  heard  every  Saturday  morning  on  schedule  through 
winter.  No  complete  failures,  though  sometimes  too  weak 
for  effective  two-way  communication. 

W2UXP,  Webster,  N.  Y.  —  Having  fine  QSOs  on  220 
Mc.  with  W2P0M,  W2MHU  and  K2CEH.  Tripler-ampli- 
fier  for  432  Mc,  with  9903s,  finished  and  crystal-controlled 
converter  well  along. 

W3UQJ,  York,  Penna.  —  A  winter  of  regular  operation 
on  220  Mc.  has  indicated  that  good  year-round  results 
could  be  obtained  on  that  band  if  more  stations  were  using 
it.  Coverage  seems  to  be  comparable  to  that  generally  ob- 
tained on  144  Mc.  Even  very  low  power  does  well  if  a  good 
antenna  system  is  used.  Schedules  have  been  kept  regularly 
with  W4UMF,  Arlington,  Va.,  over  80  miles  of  irregular 
terrain,  using  only  8  watts.

QST  for 


Simulated  Emergency  Test  — 1954  Model 

Genuine  Emergencies  Compete  with  Emergency-Preparedness  Plans 
To  Make  the  1954  SET  Realistic 

BY  GEORGE  HART.  WINJM 


THE  SET  had  a  lot  of  competition  this  year, 
especialh'  in  the  East.  Those  AREC  groups 
who  were  not  girding  for  the  next  hurricane 
were  recovering  from  the  last  one.  In  Indiana,  a 
tornado  or  two  wiped  out  a  couple  of  towns  and 
all  SET  plans  with  it.  In  other  places  also,  Old 
Dame  Nature  cooperated  pretty  well  with  us, 
this  year,  to  take  the  "simulated"  out  of  SET, 
and  put  the  gang  to  the  real  test. 

Many  of  the  AREC  organizations  so  afflicted 
simply  did  not  feel  like  putting  on  an  SET  on 
top  of  all  their  other  labors  in  connection  with 
the  real  emergency,  and  we  don't  blame  them. 
Others  submitted  the  regular  SET  form,  but 
crossed  out  the  word  "simulated"  and  reported 
their  operation  in  the  real  emergency.  After 
giving  the  matter  some  thought,  we  have  decided 
that  those  who  did  this  should  certainly  receive 
credit  for  participating  in  the  SET.  After  all, 
what  can  be  better  practice  for  operating  in  an 
emergency  than  operating  in  an  emergency? 

All  this  hullabaloo,  of  course,  put  a  crimp  in 
our  over-all  SET  participation.  Of  our  1700-odd 
ECs,  142  reported  participation  in  the  SET. 
Fifty-eight  of  these  chose  to  conduct  their  SETs 
at  dates  other  than  the  October  9th-10th  week 
end,  ranging  from  October  3,  1954,  to  February 
22,  1955.  Several  ECs  indicated  that  no  SET  was 
held  because  they  felt  it  unnecessary  in  view  of 
regular  drills  in  their  emergency  program. 

Twenty-nine  groups  bettered  their  1953  score. 


and  twenty-four  fell  short.  This  makes  53  who 
had  an  SET  in  1953  who  repeated  the  process  in 
1954,  leaving  89  new  reporting  groups.  This  about 
follows  the  pattern  of  previous  years  participa- 
tion of  repeaters  and  new  groups  in  the  SET. 

Traffic  on  the  long-haul  circuits  was  light, 
due  to  the  decrease  in  participation  and  the 
increasing  tendency  of  AREC  groups  to  take 
advantage  of  the  latitude  in  dates.  Seventy-seven 
ECs  reported  their  SET  participation,  or  lack  of 
it,  by  radio.  All  but  one  of  these  were  received 
at  Headciuarters  by  radio. 

The  Test  Emergency  Alert,  an  innovation  in 
our  annual  SET,  went  over  "like  a  lead  balloon." 
The  transmission  was  made  from  WlAW  only, 
by  'phone  at  2030  EST  on  October  9th,  on  four 
National  Calling  and  Emergency  'phone  fre- 
quencies (3875,  7250,  14,225,  21,400  kc.)  and  at 
2100  EST  bv  c.w.  at  18  w.p.m.  on  four  NCE 
c.w.  frequencies  (3550,  7100,  14,050,  21,050  kc.). 
Si.xteen  amateurs  reported  reception  of  the  mes- 
sage. Six  of  them  sent  in  100%  correct  copies 
after  having  confirmed  reception  by  radio  as  in- 
structed in  the  TEA  message  itself.  The  winnahs: 
WIBDI,  WICRW.  \V4BAQ,  W4YZE,  W8CCN, 
W0NIY.  Three  amateurs  sent  messages  confirm- 
ing recei)tion,  but  the  mail  copies  turned  out  to 
be  incomplete:  \V4C0Y,  W8AQ,  VE2HD. 
W4ERK's  copy,  by  mail  only,  was  also  imperfect. 
The  following  confirmed  reception  bv  radio  but 
did  not  send  in  copy:  WlCWX,  WlLKP,  Wl- 


This  is  the  communications  control  center  for  the  city  of  St.  Lamliert,  Que.,  as  it  was  operated  during  the  SET.  Tt 
is  operated  under  the  call  VE2ADX,  of  the  South  Shore  Amateur  Radio  CUib.  There  are  four  amateurs  in  the  pic- 
ture: EC  VE2KG  (standing)  and  seated,  starting  from  the  left.  \  F.2TE.  VE2CA  and  VE2X  Y.

QMB,  W4BUA,  W4CZR,  W4WXZ.  We  thank 
all  for  participating  in  this  test;  you  all  rate 
honorable  mention  and  an  E  for  Effort  even  if 
you  didn't  copy  100%.  Many  of  those  who 
copied  the  TEA  did  so  only  because  they  left 
receivers  tuned  to  one  or  the  other  of  the  NCE 
frequencies  all  the  time,  to  be  sure  not  to  miss  it. 
Many  others  reported  monitoring  for  hours  at 
a  time  without  success. 

Maybe  we're  just  obstinate,  but  we  still  think 
the  TEA  is  a  worth-while  part  of  the  SET.  What 
do  you  think?  At  the  moment,  we're  planning  to 
try  it  again  in  1955,  but  we  can  be  talked  out  of 
it.

CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD/9 


How: 

We  came  to  the  end  of  the  business  portion  of 
our  first  post-DX  Test  club  meeting  and  the 
l)oys  sat  back  for  the  usual  informal  finale  of  our 
monthly  get-together.  Inasmuch  as  two  of  our 
gang  were  being  evicted  by  their  landlords,  to- 
night's discussion  appropriately  was  titled  "How 
to  Select  a  DX  QTH." 

Chairman  Bandspread  McSwindle,  who  has 
715  feet  of  20  meters  on  the  dial  of  his  homebrew 
superhet,  first  called  upon  Cunningham  Plotch, 
our  most  recently  established  200-country  man. 
Cunningham's  explanation  for  his  shack's  loca- 
tion was  disappointing:  "Shucks,  the  XYL  liked 
all  the  closet  space." 

McSwindle  then  tackled  Skeds  Stamplicker,  a 
guy  who  earned  his  DXCC  the  hard  way  with 
12.3  watts  input  and  a  scratchy  receiver  volume 
control.  Skeds'  reply  didn't  bring  the  house 
down,  either:  "Gee,  the  best  pizzeria  in  town  is 
right  across  the  street  and  they  don't  deliver." 

Next  came  the  uninspiring  lowdown  on  why 
Bugbeater  Butterby  has  a  shack  on  the  top  floor 
of  a  bowling  alley:  "Won  a  suit  against  the  place 
for  bruises  suffered  while  working  as  a  pinboy." 
Also  how  come  Svishy  Svensen  keeps  his  station 
in  the  back  of  his  fish  store:  "The  tuna  vat  makes 
a  good  ground  for  an  80-meter  vertical."  (A 
paradox  becoming  evident  was  that  all  these 
birds  with  crummy  QTHs  were  the  most  active 
and  eager  DX  men  in  the  club  I) 

Well,  we  all  began  to  realize  that  we  were 
getting  nowhere  speedily.  The  discussion  was 
turning  out  to  be  as  constructive  as  a  rubber 
crutch.  But  just  as  disgusted  Chairman  Mc- 
Swindle was  about  to  adjourn  the  session  and 
forget  the  whole  thing,  in  walked  Acres  O'Green, 
late  to  another  meeting  as  usual. 

Now  everybody  knew  that  Achy  had  the  best 
DX  QTH  in  the  club.  Brother,  what  a  spot.  And, 
sure  enough,  when  Bandspread  asked  him  about 
it  Acres  described  in  glorious  detail  how  he  went 
about  selecting  such  a  marvelous  location.  He 
had  called  in  seven  communications  engineers 
who  took  noise  and  f.s.  readings  all  over  the 
place.  The  ground  conductivity  was  investigated 
by  three  other  specialists.  Surveyors  checked 
the  elevation  and  general  topography  for  miles 
in  every  direction.  Acres  left  nothing  to  chance 
and  no  propagational  pebble  remained  unturned. 

After  several  months  of  such  monkey  business 
Acres  built  a  bungalow  on  the  stake  and  installed 
a  classy  shack.  All  his  pains  were  worth  the  ef- 
fort —  man,  did  that  boy  get  out.  Any  old  time 
Achy  tapped  his  key  or  whispered  into  his  mike 

*  Xew  Mailing  Address:  Effective  immediately,  please 
mail  all  reports  of  DX  activity  to  DX  Editor  Newkirk's

the  ZC3s  and  VQ9s  came  back  on  their  hands 
and  knees. 

O'Green  concluded  his  lecture  with  the  ortho- 
dox "Any  questions?"  and  somebody  up  front 
came  through  with  the  natural  one:  "Say,  Achy, 
tell  us  how  many  multipliers  you  piled  up  in  the 
Test,  huh?"  Our  guest  of  honor  by  default 
scratched  his  chin,  thought  a  moment,  then 
looked  uncomfortable. 

"Well,  fellows  —  ah-h  —  decided  to  do  a  little 
rebuilding,  you  know.  That  was  in  1952,  come  to 
think  of  it.  Then  somebody  loaned  me  a  couple 
of  LP  records  and  I  kinda  got  hopped  up  on 
hi-fi.  Haven't  gotten  around  to  finishing  up  the 
rig.  And  that  reminds  me  —  I've  just  come  from 
my  monthly  meeting  of  the  Beebop  Lovers  of 
East  Podunk.  I'm  president,  you  know,  and  the 
club  wanted  me  to  tell  you  birds  to  get  your 
darned  harmonics  the  heck  off  WOOF-FM  on 
Sunday  afternoons.  ..." 

Bandspread  McSwindle  himself  led  the  sturdy 
little  band  that  picked  up  Acres  O'Green,  handed 
him  his  Homburg  and  neatly  heaved  him  out 
the  door. 

What: 

But,  as  McSwindle  observed  on  the  way  home  from  that 
meeting,  O'Green  will  be  back.  They  always  come  back. 
And  sure  enough,  Achy  could  be  heard  going  after  ZD8AA 
and  PJ2MA  on  20  and  40  with  his  exciter  the  following 
night. 

Some  of  the  vast  treasure  hoard  on  Cocos  Island  was 
freely  ladled  out  by  TI9MHB  beginning  early  in  February. 
Not  material  wealth,  that  is,  but  QSOs  by  the  thousands, 
contacts  with  one  of  the  rarest  entities  on  the  ARRL  DXCC 
Countries  List.  W6MHB  officiated  in  this  charity,  ably 
assisted  by  a  Viking  rig,  NC-183  and  HQ-120  receivers,  and 
a  few  bulky  spools  of  hard-drawn  copper.  TI9MHB  aimed

for  10,000  Al  and  A3  QSOs  on  10  through  160  meters  and 
was  operated  in  ideal  niaximum-contacts-per-hour  fashion. 
Whether  or  not  the  hunt  for  cached  doubloons  and  pieces 
of  eight  pays  off,  the  hamming  aspect  of  this  venture  stands 
an  unquaUfied  success.

The  1955  U.  S.  Antarctic  Expedition  buttoned  up 
aboard  U.S.S.  Atka  and  left  New  Zealand  for  southern 
adventure  in  early  January  with  W2ZK  as  the  only 
ham  included.  Just  before  sailing,  this  photo  wa- 
snapped  of  (I.  to  r.)  W2ZK,  ZL2JF,  ZL2ASL,  chief 
radiop  Dehetre  of  Atka  radio  NMBT,  ZL2ASL's  jr.  oj), 
and  ex-ZL2G0,  father  of  ZL2ASL.  It  ^*^ll  be  W2ZK5 
third  Antarctic  ordeal,  for  Bud  is  a  veteran  of  the  1934- 
1935  and  1946-1947  Byrd  explorations.  He  well  knows 
what  it's  like  to  spend  "three  days  and  nights  on  the 
roof  of  an  auto  tractor  in  pitch  darkness  at  70  degrees 
below."  We'll  take  a  mild  spring  in  good  old  U.  S.  A.!

Asia  — From  HZIAB  (W6CRV):  "Latest  estimate  of 
the  number  of  QSOs  by  this  station  in  the  past  two  years  is 
about  50,000,  most  of  these  between  June  of  '53  and  June 
of  '54  when  the  station  was  on  about  20  hours  a  day. 
About  QSLs  —  we  have  ordered  new  ones  which  should  be 
here  any  day.  When  they  get  here,  QSL  bureaus  can  expect 
batches  as  soon  as  we  get  them  made  out."  HZlAB's  cur- 
rent schedule  allows  for  14-Mc.  work  from  1030  to  2200, 
7  Mc.  around  2100-0200,  3.5  Mc.  (infrequently)  at  0200,

airmail  costs  an  equivalent  32  cents WIPWK,  who 

answered  all  SWL  cards  while  operating  CN8EG,  tells  of

he  had  previously  sent  a  fast  reception  verification  ._._._

of  portable  gear  is  all  that  keeps  ZSSN'Z  from  trying  ZS7

Oceania  —  Writing  from  New  Zealand  just  before  he 
departed  for  Antarctica  with  this  year's  Byrd  Expedition, 
W2ZK  states  that  it  is  extremely  doubtful  that  ham  activ- 
ities will  be  carried  on  from  the  frozen  bases.  MARS  call 
sign  A2ZK/MM  was  assigned  to  Bud  for  use  aboard  USS

1940 W2AIS,  of  ZC8  and  KH6  renown,  dropped 

into  Hawaii  for  a  fast  visit W9PUH,  whose  favorite 

amateur  band  is  1215  Mc,  writes  from  the  PhiUppines 
that  chances  of  U.  S.-personnel  licensing  there  appear  as 
dim  as  ever.  The  closest  approach  is  MARS  operation  at 

Clark  AFB Via  VK6MK,  W3JNN  and  WIWPO 

we  learn  that  ex-VKlJC's  Heard  Island  log  inadvertently 
was  destroyed  by  fire.  A  bad  break  —  no  more  VKIJC 
QSLs  can  be  forthcoming  ._._._  With  an  assist  from 
W6MUR,  further  research  at  the  Hq.  DXCC  desk  estab- 
lishes that  the  islands  of  Fakaofo,  Nukunono  and  Atafu 
should  be  included  in  the  Tokelaus  but  that  Manihiki, 
Rakahanga,  Penrhyn  (Tongareva)  and  Pukapuka  (Danger) 
are  to  be  counted  as  among  the  Cook  group  ._._._  Club

The  survey  of  Region  I  (FCDA)  facilities  is  in 
progress  and  the  Civil  Defense  Radio  Test  men- 
tioned in  December  QST  is  to  take  place  on  April 
30th.  Tentative  plans  for  traffic  (making  fullest 
use  of  RACES  frequencies)  are  to  be  completed 
at  a  March  meeting  of  ROs  and  SECs  of  New 
York,  New  Jersey  and  New  England.  All  ama- 
teurs in  these  states  are  urged  to  find  out  from 
their  EC,  RO,  SEC  or  SCM  if  necessary:  (1) 
Any  radio  test  details  too  late  for  this  issue  of 
QST.  (2)  How  they  can  take  part  or  assist.  (3) 
How  to  get  registered  with  the  AREC  or  signed 
up  to  help  under  any  applicable  RACES  plans. 

RACES  Progress.  It  has  been  some  time  since 
we  reported  the  number  of  approved  RACES 
plans.  FCC's  latest  Annual  Report  indicated  89 
such  plans  approved  during  the  fiscal  j^ear  that 
ended  last  June  30th,  also  754  RACES  stations 
had  been  authorized.  As  of  the  end  of  1954  we  are 
informed  bj^  the  Federal  Civil  Defense  Adminis- 
tration that  165  RACES  plans  now  have  been 
approved,  another  76  in  just  the  last  si.x  months. 
Besides  this  we're  advised  that  55  more  are  under 
study.The  latest  figure  on  amateur  station  RACES 
authorizations  (December  31,  1954)  indicates 
1254  RACES  station  authorizations  then  had 
been  issued.  A  full  fledged  nationwide  test  of 
stand-b}'  radio  communications  dedicated  to  civil 
defense  purposes  is  planned  to  accompany  the 
coming  June  14th-15th  general  c.d.  alert.  Ama- 
teurs not  identified  in  RACES  or  AREC  should 
make  local  inquiry  of  Radio  Officers  and  ARRL 
ECs  to  register  facilities  and  ask  where  they 
may  serve  in  connection  with  this  and  future  calls 
for  civil  defense  emergency  or  natural  disaster 
radio  circuits. 

Directory  of  School  Amateur  Radio  Clubs. 
A  new  1955  directory  lists  detailed  information 
on  109  high  school  clubs  with  active  stations,  26 
additional  stations  identified  with  schools  and 
college  stations  identified  with  the  prep  school 
net  and  a  college  amateur  net.  This  must  be  an-

nounced  as  available  to  other  schools  that  in  asking 
for  the  directory,  will  furnish  data  for  a  listing 
of  their  own.  Give  your  school  club  name,  its 
station  call,  address,  officers'  names,  bands  oper- 
ated, whether  schedule  is  desired,  days  and  hours 
desired,  frequency  used,  number  of  club  members, 
number  of  licensed  operators,  and  dues.  This 
High  School  Club  Directory  is  not  available  from 
ARRL,  but  from  Department  of  Health,  Educa- 
tion, and  Welfare,  Mr.  Willis  C.  Brown,  W3HB, 
Specialist  for  Aviation  Education,  Office  of  Edu- 
cation, Washington  25,  D.  C. 

Taking  Stock.  There  are  a  good  many  ways  to 
review  progress  as  an  individual  amateur  opera- 
tor. Post  mortems  after  Field  Day  or  other  activi- 
ties enable  us  to  improve  procedure  and  know- 
how  and  to  plan  which  bands  to  work  next  time. 
In  "taking  stock"  we  feel  each  amateur  should 
consider  whether  he  has  or  can  take  a  part  in  a 
local  AREC-RACES  program,  holds  ARRL  ap- 
pointments to  constructive  ends,  reports  in  his 
Section  Net,  etc.  Only  thus  does  the  individual 
derive  the  benefits  reflected  from  an  organized 
amateur  radio  which  carries  more  than  casual 
implications. 

The  Detroit  Amateur  Radio  Association 
stressed  this  principle  of  review-and-action  in  its 
QMN  Bulletin  recently.  President  Moline, 
W8GB,  delineated  five  points  to  be  checked  by 
club  member  amateurs  looking  to  individual  and 
group  progress  in  Amateur  Radio.  Resolutions 
suggested  by  the  DARA  treatment: 

(1)  To  come  to  club  meetings  often,  with  a  purpose  to 
make  the  club  a  better  one  and  meetings  interesting  and 
enjoyable. 

(2)  To  check  safety  features  of  one's  rig,  from  a.c.  outlet 
to  antenna,  prov-iding  against  hidden  hazards. 

(3)  To  help  newcomers  to  our  hobby,  particularly  those 
younger  and  less  experienced. 

(4)  To  complete  shielding  on  TVI  treatment  of  every 
transmitter,  so  all  can  operate  without  bothering  decent 
versions  of  the  one-eyed  monster. 

(.5)  To  ask  one's  self,  "  what  am  I  doing  in  amateur  radio 
that  has  public  service  to  country,  state  or  community  or 
our  organized  amateur  radio." 


Early  in  February,  we  got  together  with  some  Civil 
Defense  "brass"  to  discuss  RACES  matters  in  general 
and  tbe  forthcoming  FCDA  Region  1  RACES  test  in 
particular.  During  the  noon  hour,  \\  IBDI  lined  us  up

QST  for 


Check  Rigs  and  WWV  To  Avoid  Off-Fre- 
quency Citations.  W2FE  (00)  reported  early  this 
year  that  "A  lot  of  W  and  K  stations  are  observed 
working  phone  beyond  the  14.2-14.3  Mc.  limits. 
Stations  in  the  14.1-14.2  sector  were  heard  caUing 
CQ  15,  so  apparently  some  of  their  multiplier 
stages  are  radiating  from  a  poorlj'-shielded  ampli- 
fier." According  to  00  reports  the  calibrations  of 
15-meter  phone  band  edges  are'not  appropriately 
checked  back  against  WWV  by  some  of  the  opera- 
tors with  VFOs. 

Stations  newly  on  the  air  (especially  Novices) 
may  well  request  some  amateurs  they  work  to 
listen  for  their  exact  harmonic  to  see  if  the  har- 
monics, especially  the  third,  are  being  heard  at 
any  distance.  A  grid-dip  or  absorption  frequency 
meter  can  show  up  such  defects  in  your  equip- 
ment too.  We  mention  this  since  00s  still  report 
hearing  WN  harmonics  quite  plentiful.

We  also  learn  indirectly  that  one  Novice  was 
allegedly  taken  in  by  a  mail  approach  (for  cash 
money)  resembling  an  off  frequency  citation  from 
one  of  the  FCC  monitoring  stations.  Asking  for 
money  with  citations  is  something  not  in  the  FCC 
pattern  of  such  notices.  See  pars.  12.153-4-5  of 
our  regulations  for  what  to  do  about  citations; 
also  note  that  FCC  penalties  following  an  unsuc- 
cessful history  of  regulation  observance  generally 
take  the  form  of  a  direct  "suspension  of  license" 
where  required,  not  a  fine!  Cash  penalties  are 
provided  in  Sections  501  and  502  of  the  Com- 
munications Act  upon  conviction  b}^  the  Justice 
Department  of  willful  violations.  Regarding  har- 
monics, ARRL  Official  Observers  are  doing  all 
they  can  to  help  fellow  amateurs  keep  out  of 
trouble.  In  addition,  amateurs  actively  operating 
are  requested  to  especially  watch  the  harmonic 
shadows  of  our  bands,  especially  those  falling 
in  non-amateur  territory  so  they  can  check 
themselves  and  others.  By  notification  to  a 
brother  amateur  of  a  signal  heard  out  of  the 
bands,  either  by  message  or  postal  card,  any 
amateurs  having  unduly  strong  harmonics  may 
be  assisted  to  avoid  an  FCC  notice. 

Ready  for  Field  Day?  For  some  months  the 
activities  calendar  has  carried  the  announcement 
of  Field  Day  dates,  June  25th-26th.  That  is  not 
so  many  weeks  away  now.  We  therefore  suggest 


that  all  hands  plan  for  early  completion  of  any 
new  gear  to  be  tested  in  this  year's  Field  T>st.y. 
Year  'round  use  of  emergency-portable  and  mo- 
bile gear  is  of  course  to  be  highly  recommended. 
Devices  in  daily  use  are  conditioned  for  surest 
stand-by  dependability  when  the  chips  are  down. 
A  rig  on  the  shelf  has  greater  likelihood  of  re- 
fjuiring  work  to  repair  it  as  well  as  time  to  rewii-c 
it  and  get  the  hang  of  the  controls. 

So  get  3-our  gear  in  use  ahead  of  time  and  in 
any  event  plan  to  test  it  in  intensive  operation 
come  FD!  Don't  miss  getting  in  the  fun  this  year. 
Log  forms  for  report  of  ARRL  Field  Day  stations 
will  become  available  about  the  last  week  in  May. 
A  letter  or  radiogram  will  bring  yours  gratis.  All 
affiliated  clubs  have  already  received  complete 
copies  of  the  Field  Dav  rules  which  will  be  re-run 
in  June  QST.Cu  FD?  —  F.  E.  H.

A  far-western  trio,  composed  of  W6LDR,  W7BSU  and 
W7PCZ,  showed  other  .ARRL  appointment  holders  a  thing 
or  two  in  the  .Januarj'  c.w.  CD  Party,  Los  Angeles  ORS 
W6LDR  setting  the  pace  with  316  QSOs  in  63  sections.  The 
'phone  party  was  anotlier  contest-type  workout;  easterners 
W4FV.  W2AEE  and  W4TV0  lead  "the  voicesters. 

The  highest  scores  follow-.  Figures  after  each  call  indicate 
score,  number  of  contacts  and  number  of  ARRL  sections 
worked.  Final  and  complete  results  will  appear  in  the  April

Our  next  CD  Parties  are  coming  up  this  month.  Any 
holder  of  an  ARRL  appointment  or  office  will  be  eligible^ 
to  take  part.  If  you're  interested  in  organized  operating 
activities  and  do  not  already  hold  an  appointment,  see  the 
list  in  the  booklet  Operating  an  Amateur  Radio  Station  or 
the  Handbook  and  decide  which  appointment  suits  your 
interest  and  qualifications.  Then  write  your  SCM  or  the 
ARRL  Communications  Department  for  complete  informa- 
tion on  how  to  qualify  for  the  appointment  of  your  choosing. 

WlAW  OPERATING  NOTE 

Effective  April  24,  1955,  all  WlAW  operation  as  detailed 
on  page  71,  March  QST,  will  change  to  Eastern  Daylight 
Saving  Time.  This  means  that  to  copy  code  practice, 
bulletins,  etc.,  you  will  have  to  listen  one  hour  earlier  by 
your  clock  if  you  are  in  areas  which  remain  on  standard 
time.  Similarly,  all  general  operation  shown  in  the  chart 
on  page  70,  September  1954  QST,  will  be  conducted  on 
EDST  instead  of  EST  until  further  notice.  The  complete 
WlAW  summer  schedule  of  operations  will  appear  in  the 
Operating  News  section  of  May  QST.

iM.j~-^':->'  ...A 


This  year's  winner  of  General  Eleotric's  Edison  Award, 
as  noted  elsewhere  in  this  issue  of  QST,  is  Ben  Hamilton, 
W6VFT,  SEC  for  our  San  Diego  Section  and  RACES 
Radio  Officer  for  San  Diego  County,  Calif.  We  had  the 
opportunity  to  visit  Ben  and  inspect  part  of  his  installation 
last  summer.  The  award  was  presented  at  the  customary 
exercises  in  Washington  on  Feb.  10th. 

Make  no  mistake  about  it,  such  recognition  does  not 
come  easi  y  Ben  was  selected  from  a  considerable  number 
of  candidates,  after  careful  screening  of  the  qualifications 
of  each.  While  his  selection  was  a  signal  honor  to  W6VFT, 
it  is  also  an  honor,  by  reflection,  to  all  of  us  amateurs  who 
have  devoted  our  efforts  toward  civil  defense  work;  and 
that  means  most  of  the  AREC.  In  fact,  the  principal 
speaker  at  the  presentation  was  Val  Peterson,  FCDA  ad- 
ministrator, who  paid  high  tribute  to  amateur  radio,  and 
indicated  that  in  the  event  of  an  atomic  attack  it  was  quite 
possible  that  RACES  might  be  the  first  and  only  means  of 
communication  in  the  immediate  post-attack  period. 

Does  that  frighten  you  a  littleY  It  should.  It  should 
frighten  all  of  us  out  of  any  complacency  or  lethargy  we 
might  be  experiencing  and  get  us  going  toward  a  bigger 
and  better  RACES  through  our  own  AREC.  Because,  just 
as  the  Edison  Award  to  W6VFT  for  civil  defense  (RACES) 
work  is  a  tribute  by  implication  to  all  of  us,  the  responsi- 
bility of  being  prepared  to  provide  the  first  and  only  imme- 
diate post-attack  communication  is  a  serious  and  sober- 
ing one 

W9UQT  reports  on  the  work  done  by  amateurs  in  the 
ice  storm  which  centered  about  Clinton,  111.,  on  Decem- 
ber 30th.  The  storm  lasted  about  24  hours,  and  work  done 
was  principally  on  behalf  of  the  Illinois  Central  Railroad, 
who  asked  the  amateurs  to  help.  W9KRH/9  was  set  up 
at  the  ICRR  depot  for  the  period  of  the  emergency,  manned 
by  W9KRH,  W9I\:KN,  W9PEK  and  W9VHD.  Some  40 
railroad  traffic  items  were  handled  by  amateur  radio  that 
could  not  be  handled  any  other  way.  As  usual,  the  Illinois 
Emergency  Net  went  into  operation  almost  immediately 
on  3940  kc.  There  was  full  cooperation  of  all  net  members 
standing  by,  ready  to  help  when  possible.  Doc  mentions 
the  work  of  W9KXN  as  especially  noteworthy,  and  also 
commends  W9WHH  and  W900L  for  their  untiring  efforts 
in  relaying  and  keeping  the  frequency  cleared.  The  follow-

Members  of  the  HuntsvUle  (Ala.)  Amateur  Radio  Club 
turned  out  on  Feb.  1st  when  a  tornado  struck  Normal,  a 
small  community  north  of  Huntsville,  and  took  the  control

off  the  air.  Promptly  at  the  scene  of  principal  damage,  in

YQE/m  ZSB  and  KN4AIL.  All  but  one  of  these  are  AREC 
members.  First  news  of  the  damage  was  brought  from  the 
affected  area  to  the  city  by  amateur  radio. 

Amateurs  in  South  Dakota  joined  forces  with  law- 
enforcement  agencies  in  late  January  to  help  track  down 
a  bank  robber.  W0OOZ  and  other  members  of  the  Sioux 
Falls  .Amateur  Radio  Club  spread  the  alarm  along  four 
states  following  the  bank  robbery  at  Harrisburg,  S.  Dak., 
requesting  that  all  amateurs  notify  their  local  police  and 
the  small  towns  notify  their  garages  and  filling  stations  in 
the  area.  Although  the  robber  hasn't  been  caught  yet, 
amateurs  received  high  praise  from  the  sheriff'  of  Minne- 
haha County  for  their  efforts. 

.\nother  instance  of  amateurs  assisting  in  highway  acci- 
dents. On  October  18th,  W2GKP  received  an  emergency 
call  from  W2BRP/m  on  10  meters  at  the  scene  of  an  auto- 
mobile accident  on  tlie  West  Side  Highway  in  New  York 
City.  W2BRP  requested  an  ambulance  via  W2GKP.  The 
ambulance  arrived  on  the  scene  within  three  minutes. 


"During  the  afternoon  of  Feb.  6th  there  was  a  weather 
warning  for  possible  tornadoes  in  the  area  covering  most 
of  middle  Georgia.  As  EC  of  Houston  County,  Ga.,  I 
started  a  net  on  3995  kc.  to  keep  a  frequency  clear  in  case 
of  an  emergency  —  also  to  gather  weather  information. 
W0RV/4  alternated  with  me  as  net  control."  —  WoRDP/4, 
EC,  Houston  Co.,  Ga. 


On  Feb.  5th,  the  police  chief  of  Dartmouth,  Mass.,  called 
for  volunteers  to  assist  in  searching  for  a  missing  seven- 
year-old  boy.  Local  amateurs  turned  out  to  assist,  under 
direction  of  Assistant  EC  WIWGN.  New  Bedford  mobiles 
Wis  AGG  AZY  and  ZPE  also  responded.  WICDO  acted 
as  relay  station  in  New  Bedford.  From  Fairhaven,  mobiles 
Wis  AWH  ONK  and  ZHC  responded,  with  WIAPN  for 
fixed  relay.  WIBMQ  was  also  on  hand  with  his  mobile 
from  Dartmouth.  The  amateur  mobiles  cooperated  with 
Dartmouth  Police,  the  Dartmouth  Fire  Department,  the 
CAP  and  the  Coast  Guard  in  providing  thorough  commu- 
nications coverage  of  the  search  area.  The  story  has  a  sad 
ending  —  the  boy's  body  was  recovered  from  the  bottom 
of  Padanaram  Harbor  —  but  amateurs  were  on  the  job 
to  do  wh.it  they  could,  as  usual. —  WIAVY,  EC,  New 
Bedford,  Mass. 

Tennessee  SEC  W4RRV  tells  us  that  for  some  time  he 
has  wished  to  do  something  to  encourage  the  Novice  li- 
censee to  become  actively  interested  in  emergency  work. 
Now  he's  done  something  about  it.  On  Feb.  2d,  the  Tennes- 
see Novice  Emergency  Net  came  into  existence  on  3737  kc. 
The  net  will  have  only  Novices  for  members,  except  for 
the  NCS,  who  will  hold  appointment  as  an  EC  and  will 
be  General  Class  or  better.  Within  the  .\REC  organiza- 
tion, the  net  will  act  as  a  unit  under  its  EC,  with  the  latter 
issuing  AREC  member  cards.  W4RRV  figures  on  an  almost 
complete  turnover  every  six  months  as  Novices  get  their 
General  Class  licenses  and  "graduate"  to  their  local  .\REC 
units  as  full-participating  members. 

Fifteen  SECs  reported  December  activities  of  4620 
.\RP2C  members,  to  wind  up  our  1954  season.  Two  new 
sections,  Missouri  and  Minnesota,  put  in  their  appearance 
in  December  reports,  making  it  31  sections  heard  from 
during  1954,  a  total  of  178  SEC  reports  received  during 
the  year.  This  compares  favorably  with  the  figures  for 
1953  and  1952:  in  1952,  204  reports  were  received  from  29 
sections,  and  in  1953  154  reports  were  received  from  25 
sections.

RACES  News 

Amateurs  in  the  New  England  States,  New  York  and 
New  .Jersey  (FCDA  Region  I),  will  be  readying  themselves 
for  the  April  30th  test  of  RACES  facilities  to  be  held  in 
that  FCDA  Region.  If  you  live  in  Region  I  (above  states), 
it  behooves  you  to  get  signed  up  in  your  local  AREC 
or/and  RACES  group  with  a  view  to  contributing  your 
strength  to  this  display  of  amateur  radio  potential.  The 
First  Region  is  just  a  guinea  pig,  to  give  FCDA  an  idea 
what  can  be  expected  of  amateurs  and  RACES  in  the 
forthcoming  June  14th-15th  nationwide  exercise.  Organ- 
izers in  other  regions  please  take  note  that  your  region  is 
not  being  left  out.  While  there  will  be  no  otlier  FCDA- 
sponsored  tests  on  that  date,  tlie  capability  of  amateurs 
in  RACES  in  your  region  will  be  judged  on  the  basis  of 
the  performance  of  amateurs  in  Region  I,  and  plans  for  the 
June  nationwide  test  made  accordingly.  So  this  April  30th 
test  is  not  a  signal  for  you  to  relax  and  let  Region  1  do  it, 
but  a  notice  to  make  sure  your  region  can  make  as  good  a 
showing  as  Region  1  in  any  test  of  your  RACES  facilities, 
real  or  fancied. 


Some  time  ago  ARRL  sponsored,  at  FCDA  request,  a 
competition  to  design  a  RACES  emblem,  to  be  adopted 
as  the  official  RACES  emblem  by  FCDA.  Many  sugges- 
tions were  received  and  sent  down  to  FCDA  for  considera- 
tion. After  extensive  de- 
liberation, a  design  most 
nearly  following  one  sug- 
gested by  WIJMY  was 
adopted  and  promul- 
gated as  the  official 
RACES  insignia  as  of 
March  4,  1954.  We  don't 
believe  we  have  ever  re- 
produced this  emblem  in 
QST.  Note  that  there  is 
room  for  inclusion  of  the 
name  of  a  city  or  county 
(or  even  a  state)  at  the 
top  of  the  emblem,  and 
such  inclusion  is  con- 
templated. This  emblem  can  be  used  by  RACES  personnel 
in  the  same  manner  as  the  regular  civil  defense  insignia,  as 
prescribed  by  FCDA  regulations  on  July  12,  1952.  We  wish 
to  express  belated  thanks  to  all  amateurs  who  submitted  a 
design,  some  of  them  at  considerable  trouble. 


The  Warning  and  Communications  Office  of  FCDA  now 
has  Charles  E.  Dewey,  W8LBM,  formerly  W0LBM  of 
Jefferson  City,  Mo.,  on  its  staff  to  implement  the  RACES 
program.  Charlie  is  no  stranger  to  us,  having  participated 
with  us  in  the  week-long  FCDA  Communications  Confer- 
ence at  Olney,  Md.,  in  1951.  He  is  also  no  stranger  to 
RACES,  having  served  as  RACES  state  radio  officer  for 
Missouri.  Another  amateur  will  soon  be  on  the  FCDA  staff 
to  assist  Charlie  in  this  work,  so  we  can  look  for  some  prog- 
ress from  that  level,  and  additional  material  from  time  to 
time  for  this  column.  Other  amateurs  at  FCDA  head- 
quarters, not  necessarily  having  any  connection  with 
RACES,  are  Communications  Specialists  W4KCZ  (ex- 
K3FBG,  W9KCZ,  V04AC,  9EMC),  W4DLA  (ex-W3SEI, 
W2SEI),  W8UTQ  (ex-W4CGK,  KL7YT),  and  Electronics 
Engineer  W3UH  (ex-W5UH). 


In  the  future,  we'll  endeavor  to  include  items  on  RACES 
under  this  subhead.  This  will  include,  but  not  be  restricted 
to,  information  coming  out  of  FCDA  Headquarters  each 
month.  Short  items  from  the  field  will  be  welcomed  and 
will  be  reproduced  herewith  after  editorial  consideration 
concerning  their  suitability.  Let  us  hear  what's  going  on 
in  your  RACES  unit.

GROUP  CODE  INSTRUCTION 

Affiliated  clubs  planning  a  series  of  lessons  designed  to 
aid  tlie  code  trainee  would  do  well  to  note  the  availability 
of  .\RRL  training  aids.  One  of  the  most  useful  items,  a 
T(i-10  keyer,  produces  an  audio  tone  from  inked  paper 
tapes.  The  tapes  are  available  for  use  with  tlie  keyer  or  may 
be  made  by  use  of  another  item,  a  BC-1016  inked  tape  re- 
corder. We'll  be  pleased  to  supply  copies  of  a  Reference 
Guide  for  Code  Trainees  to  help  get  things  started.  Have  a 
club  officer  write  to  Communications  Department  for  fur- 
ther information  on  reserving  a  keyer  or  recorder  for  one 
convenient  month-long  period. 

BRIEFS 

Propagation  tests  to  determine  the  possibility  of  main- 
taining continuous  reliable  communication  on  2,  6,  75,  80 
and  160  meters  are  being  conducted  in  New  York,  New 
England  and  New  Jersey,  each  week  end  from  1800  EST 
Friday  to  1800  Saturday.  Sponsored  by  amateurs  at 
Rensselaer  Polytechnic  Institute,  the  tests  are  expected 
to  furnish  valuable  data  to  the  services  performed  by 
amateur  radio  as  well  as  amateur  communications  in  general. 
The  following  frequencies  are  being  used:  1815,  3509.5, 
and  3993  kc;  and  53.5  and  145.47  Mc.  Persons  interested 
in  participating  are  requested  to  contact  Roger  Salaman, 
Hunt  II,  RPI,  Troy,  New  York. 

The  WAM  award  will  be  made  to  any  amateur  sub- 
mitting confirmation  of  two-way  radio  contact  with  all 
sixteen  counties  in  Maine  any  time  after  12:01  a.m.  January 
1,  1955.  Inquiries  or  petitions  for  awards  should  be  addressed 
to  the  Portland  Amateur  Wireless  Association,  97  State 
Street,  Portland,  Maine. 

\  "Ground-Wave  Contest"  was  held  November  20, 
1954,  by  the  Breezeshooter's  group,  W3SIR  reports.  Com- 
petition for  contacts  was  scored  for  winners  in  four  zones. 
Zones  1-2-3-4  being,  resjjectively,  in  25-,  50-,  75-  and 
100-mile  concentric  circles  centered  on  Pittsburgh,  Penna. 
Winners  and  their  scores:  W3QYF  164,  W3SJK  156, 
W3VUZ  125  in  Zone  1 ;  W8FRV  96  in  Zone  2;  W3WJF/3  81

TRAFFIC  TOPICS 

We  thought  that  this  month  a  few  data  from  the  new 
Net  Directorj-  might  be  of  interest.  It's  quite  a  production, 
consisting  of  14  multilithed  pages  and  registering  357  net 
names  as  of  December  15,  1954  —  the  biggest  Net  Directory 
we've  put  out  yet.  These  357  net  names  are  registered  on  193 
frequency  channels  througliout  six  amateur  bands.  As  usual, 
the  3.5-4.0  Mc.  band  carries  the  brunt  of  the  net  load,  with 
101  frequency  channels  being  utilized  by  233  nets  in  that 
band.  This  is  slightly  less  than  5  kc.  per  cliannel.  The  3.5- 
3.7  Mc.  segment  uses  47  channels  (4.25  kc.  per  channel)  and 
the  3.8-4.0  Mc.  segment  used  41  channels  (4.88  kc.  per 
channel).  Tliere  are  12  channels  used  in  the  160-meter  band, 
9  on  forty  c.w.,  36  on  ten,  7  on  six  and  27  on  two  meters. 

Of  the  357  registered  net  names,  304  indicated  their  pur- 
pose. There  were  237  nets  which  indicated  a  single  purpose; 
the  others  indicated  dual  or  triple  purposes.  Of  the  single- 
purpose  nets,  118  were  devoted  to  traffic.  111  to  emergency 
preparedness,  and  8  to  rag-chewing.  There  are  also  47  nets 
devoted  to  both  traffic  and  emergency  work,  11  to  traffic 
and  rag-chewing,  7  to  emergency  and  rag-chewing,  and  2  to 
traffic,  emergency  and  rag-chewing.  This  means  that  178 
nets  can  be  called  traffic  nets,  167  can  be  called  emergency 
nets,  and  28  can  be  called  rag-chewing  nets. 

The  net  directory  is  now  available  free  of  charge  upon  re- 
quest, and  we  hope  that  net  organizers,  participants  and 
potential  participants  will  make  the  best  possible  use  of  it. 

There  still  seems  to  be  some  confusion  regarding  counting 
of  net  traffic.  As  usual,  ARRL  has  set  a  standard,  and  this 
standard  is  followed  throughout  the  National  Traffic  Sys- 
tem. Whether  or  not  your  net  follows  that  standard  is  up  to 
you,  of  course.  In  the  past,  we  have  assumed  that  net  traffic 
reported  in  this  column  has  followed  the  League's  simple 
net  traffic  counting  system.  If  such  has  not  always  been  the 
case,  then  there  has  been  little  or  no  basis  for  comparison 
between  the  traffic  totals  of  the  various  nets  reported. 

The  net  traffic  is  that  traffic  handled  by  the  net  in  directed 
session.  It  is  not  the  traffic  total  of  each  station  in  the  net; 
it  is  not  the  total  of  all  traffic  reported  into  the  net.  It  is 
purely  and  simply  the  number  of  message  handlings  between 
the  time  of  net  call-up  and  QNF.  If  a  message  is  sent  from 
one  net  station  to  another,  at  the  direction  of  the  NCS,  and 
properly  QSLd  at  the  receiving  station,  that's  one  point. 
The  net  traffic  total  is  simply  the  number  of  times  this 
process  is  repeated  during  a  net  session.  The  same  message 
cannot  be  counted  twice  unless  it  is  sent  and  received  twice 
in  the  net. 

It  would  help  if  we  all  followed  this  simple  and  logical 
procedure.  Let's  not  get  net  traffic  counting  mixed  up  with 
individual  station  traffic  totals. 

Miscellaneous  January  net  reports:  College  Net  —  63 
stations  called  in,  12  messages  handled.  Early  Bird  Trans- 
continental 'Phone  Net  —  813  messages.  North  Texas 
Oklahoma  Section  Net  —  319  messages,  979  check-ins. 
Transcontinental  Relay  Net  —  31  sessions,  five  stations, 
traffic  total  of  1260.  Transcontinental  'Phone  Net  (1st 
Dist.)  —  16  stations,  traffic  total  1817. 

W0LJW  sends  in  an  amusing  little  story.  It  seems  his 
QTH  is  afflicted  with  severe  line  noise.  One  evening  in 
participating  in  TLCN  (Iowa  NTS  Section  Net),  he  dis- 
covered there  was  traffic  for  his  city.  He  called  W0CGY 
on  the  landline  to  ask  his  assistance,  only  to  learn  that 
CGY's  transmitter  was  out  of  operation.  They  got  the 
traffic  through,  though.  W0CGY  did  the  receiving,  called 
the  "breaks"  to  his  XYL  who  relayed  them  over  the  land- 
line  to  W0LJW,  who  did  the  breaking  and  asking  for  re- 
peats. W0LJW  says  "  everything  went  fine  except  for  the 
NCS,  W0BLH,  who  thought  we  were  slightly  nuts." 


WN5GQN  reports  the  organization  of  a  net  for  Novices 
in  Texas.  It  is  called  the  Texas  Novice  Traffic  Net  (TNT) 
and  operates  on  7191  kc.  at  1900  CST  on  Tuesdays.  Dave 
(WN5GQN)  says  all  Novices  are  welcome  and  gives  the  fol- 
lowing tlirecfold  purpose  of  the  net:  (1)  to  provide  an  oppor- 
tunity for  Novices  to  learn  correct  operating  procedure; 
(2)  for  public  service;  (3)  one  of  very  few  organized  Novice 
activities. 

National  Traffic  System.  Conditions  continue  being  unkind 
to  us.  NTS  nets  have  been  beset  with  the  worst  kinds  of 


difficulties  because  of  the  long  skip  setting  in  at  about  1900 
local  time  each  evening.  Someone  not  too  familiar  with 
organized  traffic  work  recently  asked  us  why  we  were  so  un- 
adaptable, why  we  didn't  simply  handle  our  traffic  at  a 
different  time,  just  as  the  DX  man  adapts  himself  to  work- 
ing DX  at  a  different  time  when  conditions  demand  it. 
Well,  to  some  extent  we  have  done  this.  The  independent  net 
without  any  system  can  do  it  easily,  provided  a  new  net 
time  is  convenient  to  its  members.  But  NTS  must  operate  in 
chronological  sequence;  its  nets  telescope  into  each  other. 
One  of  the  main  purposes  of  NTS  is  to  work  together  as  a 
national  system,  and  you  can't  do  this  when  every  net  oper- 
ates at  a  different  time,  handles  traffic  from  and  for  all  over 
the  map,  and  pays  no  slight  attention  to  when  other  units  of 
the  same  system  operate,  or  where,  or  what  they  do. 

These  "bad"  conditions,  however,  tend  to  lead  us  in  this 
direction.  A  section  net,  because  it  can  hear  distant  stations 
but  not  its  own,  either  becomes  a  net  taking  in  a  lot  of  terri- 
tory, or  it  moves  to  an  earlier  meeting  time.  No  doubt  about 
it,  the  present  state  of  the  radio  spectrum  is  conducive  to 
hodgepodge  in  traffic  systems.  What  are  we  going  to  do 
about  it? 

Nothing.  Just  wait.  Just  continue  doing  the  best  we  can 
and  wait  for  conditions  to  get  back  to  where  they  used  to  be 
when  NTS  was  first  put  into  operation.  Maybe  then,  too, 
we  can  return  to  a  more  normal  and  uniform  NTS  time 
schedule.

Several  NTSers  have  asked  us  how  we  calculate  the 
"rate"  above,  and  a  couple  of  managers  have  disagreed 
that  the  way  we  do  it  indicates  anything.  The  "rate"  is  the 
number  of  messages  handled  per  minute  during  the  busiest 
session  of  the  month.  It  indicates  the  net's  efficiency  "under 
load."  We  apply  it  only  to  NTS  regional  and  area  nets, 
since  the  achievement  of  a  high  rate  of  traffic  handling  is 
perhaps  of  less  importance  at  section  level  where  the  main 
objective  is  representation.  Accuracy,  of  course,  is  para- 
mount at  any  speed. 

W2LPJ  reports  that  the  early  session  of  2RN  at  1815  EST 
is  handling  most  of  the  traffic.  The  dragnet  is  out  for  a  new 
3RN  manager,  «ith  W30NB  wishing  to  be  relieved;  we 
ought  to  have  one  by  this  time.  Arkansas  and  Mississippi 
remain  problems  on  RN5;  new  RN5  certificates  have  been 
issued  to  W4TYU.  W4WOG,  W5CAF,  and  W5MXQ.  RN7 
is  completely  without  r<  prfscntation  from  Saskatcliewan 
and  Alberta,  and  during  .hunutry  had  very  little  from  Mon- 
tana and  Alaska.  New  8HN  certificates  have  been  issued  to 
W8s  ILP  LHV  and  MQQ.  W9UNJ  has  difficulty  in  getting 
NCS  reports  in  9RN,  thus  the  lack  of  statistics  above; 
W4KKW,  W9CC0,  K4FBW  and  K9FCA  have  earned  9RN 
certificates.  VE3AUU  is  a  newcomer  to  the  TRN  roster.

QST  for 


TCC  continues  to  function  with  the  usual  difficulties, 
mostly  brought  about  by  the  need  for  additional  personnel 
and  inability  of  existing  operators  to  make  contact  with 
their  TCC  schedules.  W8UPB,  for  Eastern  Area  TCC, 
reports  that  there  were  34  TCC  QNIs  into  area  nets  during 
January,  with  WSDQG  handling  tlie  greatest  amount  of 
traffic.  He  needs  two  regulars,  one  on  Tuesday  to  relay 
traffic  to  PAN  via  direct  schedule,  and  one  on  Monday  (latel 
to  receive  traffic  from  PAN.  Other  scliedules  are  functioning, 
but  many  of  them  are  irregular.  WiUlM,  for  Central  Area 
TCC,  reports  that  schedules  are  working  nicely,  but  when- 
ever missed  the  station  concerned  makes  direct  contact  with 
the  Pacific  Area  Net  to  clear  traffic.  In  the  Pacific  Area, 
W6HC  reports  that  all  TCC  stations  are  active,  but  having 
difficulties.  W0EKQ  handled  the  most  traffic  (102).  The 
latest  Pacific  Area  TCC  roster  shows  W6UTV  deleted  and 
VV6PKL/0  added  to  the  list. 

There  are  still  some  openings  in  the  TCC  roster.  Write 
W8UPB,  W9JUJ  or  W6HC,  if  interested.

NONDIRECTIONAL  CQs? 

When  WIWPO  heard  a  TI2  calling  "CQ  NO  USA"  on 
7  Mc.  one  evening  recently,  he  moved  near  the  Costa 
Rican's  frequency  and  called  "CQ  NO  TI2."  The  TI2 
promptly  called  WIWPO  and  a  friendly  rag  chew  resulted 
.  .  .  WIVG  reports  use  of  iiondirectional  CQs  with  ringing 
success.  Three  times  in  a  row  Pete  called  "CQ  NO  ASIA" 
and  sure  enough,  no  Asians  replied! 

ELECTION  NOTICE 

(To  all  ARRL  members  residing  in  the  Sections  listed  below.) 

You  are  hereby  notified  that  an  election  for  Section  Com- 
munications Manager  is  about  to  be  held  in  your  respective 
Section.  This  notice  supersedes  previous  notices. 

Nominating  petitions  are  solicited.  The  signatures  of  five 
or  more  ARRL  full  members  of  the  Section  concerned,  in 
good  standing,  are  required  on  each  petition.  No  member 
shall  sign  more  than  one  petition. 

Each  candidate  for  Section  Communications  Manager 
must  have  been  a  licensed  amateur  for  at  least  two  years 
and  similarly  a  full  member  of  the  League  for  at  least  one 
continuous  year  immediately  prior  to  his  nomination. 

Petitions  must  be  in  West  Hartford,  Conn.,  on  or  before 
noon  on  the  closing  dates  specified.  In  cases  where  no  valid 
nominating  petitions  were  received  in  response  to  previous 
notices,  the  closing  dates  are  set  ahead  to  the  dates  given 
herewith.  The  complete  name,  address,  and  station  call  of 
the  candidate  should  be  included  with  the  petition.  It  is

tained, since  on  checking  names  against  Headquarters  files,

petition  may  be  found  invalid  by  reason  of  expiring  mem- 
berships, individual  signers  uncertain  or  ignorant  of  their 
membership  status,  etc. 

The  following  nomination  form  is  suggested :  (Signers  will 
please  add  city  and  street  addresses  to  facilitate  checking

Elections  will  take  place  immediately  after  the  closing 
dates  specified  for  receipt  of  nominating  petitions.  The

BRIEFS 

The  Tri-County  Amateur  Radio  Club  of  Brattleboro, 
Vt.,  is  offering  a  handsome  certificate  to  any  amateur  sub- 
mitting proof  (QSLs  or  Vermont  QSO  Party  logs)  of  two- 
way  communication  with  amateurs  in  13  of  Vermont's  14 
counties.  Send  confirmations  to  Ray  N.  Flood,  WIFPS,

tails on  the  Vermont  QSO  Party,  scheduled  for  Apr.  9th- 
10th. 


Amateur  radio  in  the  Wisconsin  area  is  looked  upon  by 
educators  as  being  a  vital  educational  experience.  As  re- 
ported by  W90TL,  at  a  Milwaukee  meeting  of  the  Wiscon- 
sin Education  Association  in  November,  1953,  a  group  of 
teachers  organized  the  Amateur  Radio  Section  of  the  WE.\ 
and  set  up  plans  for  the  Wisconsin  Educator's  Phone  Net. 
This  basic  organization  has  coordinated  the  efforts  of  state 
school  amateur  radio  clubs.  Its  individual  members  have 
demonstrated  amateur  radio  to  thousands  of  students  with 
the  result  that  several  new  school  radio  clubs  have  been 
organized  and  dozens  of  students  licensed.  To  help  train 
Novices  in  code  and  message  handling,  3735  kc.  is  used  as  a 
net  frequency  at  1220  GST  and  1630  CST  on  all  school  days. 
The  spot  3850  kc.  will  continue  as  the  WEA's  'phone  net 
frequency  at  1000  CST  Saturday  and  1530  CST  on  the 
second  and  fourth  Friday  of  each  school  month. 

CODE-PROFICIENCY  PROGRAM 

Twice  each  month  special  transmissions  are  made  to

Nets:  3610,  3850  kc.  The  following  clubs  report  new  officers 
for  1955:  Electric  City  ARC  elected  LCK,  pres.;  OST, 
vice-pres. ;  NNH,  secy.;  LJT,  treas.  Northeast  RC  of  Phila- 
delphia elected  VOC,  pres.;  TYX,  vice-pres.;  MYL,  treas.; 
K2JUW,  rec.  secy.;  DYL,  corr.  secy.;  KIW,  DWR,  HYJ, 
CLC,  and  JQP,  exec,  board.  South  PhiUy  (SPARK)  elected 
QLZ,  pres.;  FZR,  vice-pres.;  VSD,  secy.;  ZMO,  treas.  ARK. 
Pottstown  ARA  president  and  a  newly-appointed  OO,  came 
up  with  a  suggestion  that  is  worth  the  attention  of  all  clubs 
dealing  with  the  training  of  Novices.  In  monitoring  the 
Novice  bands  with  the  aid  of  two  receivers,  one  tuned  to 
the  fundamental,  the  other  tuned  to  the  second  harmonic 
frequency,  ARK  has  found  not  only  strong  harmonic  radia- 
tion from  many  in  the  Novice  bands  but  a  surprising  amount 
of  stations  calling  CQ  in  vain  on  the  "out-of-the-amateur- 
band"  second-harmonic  frequency  witliout  a  trace  of  these 
stations  on  tlie  expected  fundamental  frequency.  This  leads 
Jack  to  believe  that  these  stations  are  in  need  of  training  in 
the  use  of  a  grid-dip  oscillator  or  absorption-type  wave- 
meter.  Also,  further  training  in  the  proper  methods  of 
antenna-to-transmitter  coupling.  All  clubs  might  include 
this  in  their  Novice  training  iirogram.  Tliese  stations  need 
our  help.  It's  up  to  those  of  us  with  the  know-how  to  give 
all  the  help  possible.  BES  and  EAN  report  attending  the 
joint  meeting  of  the  FRC/PVRC  in  Washington  where 
about  80  turned  out  to  hear  about  F08AJ  and  Navassar 
expeditions.  JNQ  says  he  lost  15  pounds  while  "batching  it." 
PYF  is  home  again  after  a  three-week  business  trip  that 
took  him  through  Texas  and  Oklahoma.  CUL  also  is  back 
home  after  enjoying  a  fine  trip  to  Florida.  During  the  Janu- 
ary 18th  Aurora  opening,  TDF  worked  Illinois  on  2  meters 
to  bring  his  total  states  worked  to  seventeen.  In  answer  to 
many  queries  regarding  the  forthcoming  SCM  election, 
yours  truly  will  bow  out  in  favor  of  someone  with  more 
time  to  devote  to  the  job.  My  sincere  thanks  for  your 
cooperation  and  good  luck  to  my  successor.  Traffic:  (Jan.)

WHAT  IS  A  MICROVOLT? 


MICROVOLT  of  r.f.  across  the  antenna  terminals 
produces  an  audible  and  quieting  carrier  on  a  sensitive 
receiver  (A)  under  laboratory  conditions  with  a  signal 
generator  producing  the  microvolt.  The  receiver  is  then 
placed  in  an  amateur  station. 
A  less  sensitive  receiver  (B)  in  the  same  station  under  identical  operating  conditions 
produces  a  quieter  and  more  audible  received  signal  than  receiver  (A). 

What  is  the  difference?  The  noise  figure  could  be  better  in  (B)  but  when  measured  (A) 
is  found  to  be  superior. 

The  answer,  of  course,  is  selectivity.  Consider  a  segment  of  frequency  with  a  signal  in  its 
center.  (Fig.  1)  The  grass  on  both  sides  of  the  signal  is  noise,  mainly  man-made  and  well 
above  the  thermal  noise  of  the  first  r.f.  stage. 


Fig. 
1 


l|l       '■   ||l       111'     \:;f  l||r 

Consider  selectivity  as  a  window.  The  narrower  the  window,  the  greater  the  selectivity. 
By  placing  the  signal  in  the  center  of  the  window,  receivers  (A)  and  (B)  are  Figures  2  and 
3  respectively. 


Fig.  2 


Fig.  3 


Receiver  (A)  window  contains  the  wanted  signal  plus  a  lot  of  useless  noise.  (B)  window 
contains  mainly  signal.  (B)  will  have  the  greater  operating  sensitivity,  since  most  of  its 
accepted  spectrum  is  signal. 

Below  30  Mc.  the  noise  figure  of  a  receiver  is  seldom  realized  due  to  man-made  noise. 
Selectivity,  therefore,  is  the  important  function  in  the  majority  of  cases  with  the  noise  figure^ 
not  so  important. 

At  UHF  noise  figure  is  a  good  measure  of  operating  sensitivity  since  a  given  receiver  may 
utilize  its  i.f.  gain  until  the  amplified  thermal  noise  of  its  own  first  stages  becomes  objection- 
able.   Man-made    noise    at    these 
frequencies  is  low  enough  to  permit 
this  condition. 

The  criterion  then  for  a  good 
communications  receiver  becomes 
one  of  excellent  selectivity  with  sen- 
sitiviu-  or  noise  figure  of  secondary 
importance,  depending  upon  the 
operating  frequency.

in  compact  beams  quality  counts! 


The  "V-P"  Beam  design  was 
originally  described  in  May 
'54  QST  and  is  featured  edi- 
torially in  1955  ARRL 
HANDBOOK. 


MOSLEY  beams  are  designed  FOR 
HAMS  —  BY  HAMS.  They  are  made  as 
small  as  possible  and  still  maintain  true  beam 
performance.  Correctly  proportioned  element 
length  to  coil  inductance  results  in  high  for- 
ward gain,  good  front-to-back  ratio,  negli- 
gible end-fire  and  low  SWR  over  the  entire 
band. 

Every  part  of  a  MOSLEY  "V-P"  Beam 
is  designed  for  heavy  duty  service  in  all 
kinds  of  weather.  Although  every  model  but 
the  40  meter  beam  can  be  supported  with  a 
TV  rotator,  MOSLEY  beams  are  no  flimsy, 
light-weight  weaklings.  Aluminum  elements 
pre-cut,  pre-drilled,  pre-tuned  and  color 
coded.  One  piece  aluminum  boom.  All  non- 


ferrous  parts  plated.  Heavy  varnished  red- 
wood cross  arms  can't  cause  distortion  of 
beam  pattern.  Shipped  "knocked  down"  but 
assembly  is  quick  and  simple.  Each  model 
complete  with  coils  and  all  parts.  Ask  your 
jobber,  listed  below,  for  free  copy  of  MOS- 
LEY Catalog  H55  giving  complete  electrical 
and  mechanical  data.

I  "SECRET"  OF 

MOSLEY  BEAM  PERFORMAHCE 


Is  T/ie  Superior  Materials  And 
Construction  Of  The  Loadins  Coils 

MOSLEY  coils  are  machine-wound  on 
forms  of  the  highest  grade  ceramic.  No  loose 
hand-wound  turns  that  slip  and  change  in- 
ductance to  ruin  beam  performance.  For 
added  protection,  MOSLEY  coils  are  also 
enclosed  in  weather-proof  covers  so  that  hot 
or  cold  —  wet  or  dry,  you  get  the  same  fine 
performance.  They  stay  tuned  on  the  nose  — • 
handle  a  Kilowatt  with  ease!  Link  coupling 
to  radiator  coil  matches  52  ohm  coax  line. 

Poorly  constructed  loading  coils  are  false 
economy  if  it's  enduring  beam  performance 
that  you  want!  Compare  MOSLEY  quality, 
materials  and  workmanship.  See  them  at 
your  distributor  or  write  for  brochure.

APC  Capacitors 

With 

E-X-T-E-N-D-E-D  Sliafts 


In  response  to  many  requests  from  ama- 
teurs, experimenters  and  electronic  equip- 
ment builders,  Hammarlund  is  now 
offering  APC  -  B  Type,  and  MAPC  -  B 
Type  Capacitors  as  standard  items 
through  Hammarlund  Authorized  Dealers. 
These  are  extended-shaft  versions  of 
the  well-known  APC  and  MAPC  capaci- 
tors. They  permit  knob-control  or  shaft 
coupling. 

The  original  APC  trimmer  was  de- 
signed and  first  produced  by  Hammarlund 
more  than  20  years  ago,  and  is  used  in 
all  classes  of  equipment  where  a  compact 
high-quality  air  dialectic  trimmer  is 
needed.  The  MAPC  type  is  similar  to  the 
APC  except  that  it  is  a  miniaturized 
version. 

Range  of  the  APC  series  is  from  3  to 
140  mmf  and  for  the  MAPC,  2.3  to 
100  mmf.

HAS  "MORE 
THAN  MEETS 
THE  EYE"! 


Just  looking  at  the  outside  of  an 
HQ-140-X  communications  receiv- 
er isn't  enough,  when  you're  in  the 
market  for  a  new  rig.  Sure,  it's  in  an  attractive 
case  that's  built  for  rugged  service;  and  the  con- 
trols are  comfortably  placed  for  lengthy  DX 
operations.  But,  it's  what's  inside  the  cabinet 
that's  important. 

For  example,  the  HQ-140-X  offers  a  profes- 
sional-type tube  lineup.  The  use  of  a  separate 
mixer  (6BE6)  and  oscillator  (6C4)  contribute 
to  the  high  degree  of  oscillator  stability.  Modern 
6BA6's  are  used  for  the  RF  amplifier  and  for  all 
three  stages  of  IF  amplication  for  maximum 
efficiency. 

The  nine  individual  sections  of  the  band-spread 
capacitor,  and  the  six  sections  that  make  up  the 
main  tuning  capacitor,  at  all  times  maintain  the 
proper  L/C  ratio  regardless  of  what  part  of  the 
receiver's  range  (540  Kc  to  31  Mc)  you  use. 
Plates  are  heavy  brass,  soldered  to  their  shafts, 
built  into  a  large  sturdy  frame  for  rugged  us*. 

Features  like  those  described  above  rate  high  with 
'hams'  the  world  over.  For  detailed  information  on  the 
HQ-140-X,  write  to  The  Hammarlund  Manufacturing 
Co.,  Inc.,  460  West  34th  Street,  New  York  1,  New  York.

ANTENNA  COUPLER 

KIT 

The  new  Heathkit  An- 
tenna   Coupler    Model 
AC-1  was  specifically 
designed  to  operate  with 
the  Heathkit  Amateur 
Transmitter  and  will 
operate  with  any  trans- 
mitter not  exceeding  75 
watts  RF  input  power. 
Rugged  design  has  resulted 
in   a  sturdy,   well  shielded 
unit  featuring  a  copper  plat- 
ed chassis  and  shield  com- 
partment. Coaxial  52  ohm 
receptacle  on  the  rear 
of  the  chassis  connects 
to  a  three  section  Pi-  type  low  pass 
filter  with  a  cut-off  frequency  of  36  Mc. 
Tuning  network  consists  of  a  variable 
capacitance  and  tapped  inductance  in 
an    impedance    matching    unit.

The  SARA,  one  of  our  oldest  clubs,  celebrates  its  25th 
anniversary.  Its  record  of  achievements  has  been  outstand- 
ing and  lists  many  "firsts"  in  the  field  of  amateur  radio.  As 
an  example,  the  first  microwave  communication  on  2300 
Mc.  was  established  by  RMA  and  RYT  in  the  year  1945. 
During  the  same  year,  UKL  and  RDL  set  the  DX  record  of 
800  feet  on  21,000  Mc.  The  newly-elected  officers  are  YIV,

What's  New  with  the  Electron? 


Latest  power  tube  developments 

displayed  by  Eimac  at  annual 

I.R.E.  show 

New  and  improved  klystron,  ceramic 
and  negative  grid  tubes  highlighted  the 
Eimac  display  at  the  annual  Institute 
of  Radio  Engineers  show  and  conven- 
tion in  New  York  City,  March  21-24. 
High  power  Eimac  amplifier  kly- 
strons range  in  frequency  from  225- 
SOOOmc  and  5500-7500mc  and  vary  in 
CW  power  output  from  50  watts  to 
50kw.  Application-proved  Eimac  ampli- 
fier klystrons  such  as  type  3K50,000L, 


High  power  Eimac  amplifier  klystron 

delivering  lOkw/CW  power  output 
at  400-1050mc,  make  possible  high 
power  previously  limited  to  VHP  and 
lower  frequencies.  These  amplifier  kly- 
strons are  of  ceramic  and  copper  con- 
struction and,  although  larger  than 
negative  grid  tubes,  are  easily  the 
lightest  and  least  complicated  of  any 
klystrons  intended  for  similar  service. 
Small,  rugged  Eimac  reflex  klystrons 
are  designed  for  local  oscillator  use  as 
high  as  9600mc  in  airborne  environ- 
ments. 

Sharing  the  spotlight  with  klystrons 
were  the  latest  in  Eimac  ceramic  tube 
developments.  Ceramic  replaces  glass  in 
these  tubes,  giving  a  greater  immunity 
to  thermal  and  physical  shock,  plus 
allowing  revolutionary  construction 
techniques.  In  production,  the  ceramic 
and  electrode  parts  are  placed  one  on 
top  of  the  other,  similar  to  stacking 


Ceramic  tetrode  and  cross-section 

poker  chips.  The  copper  metallized 
seals  are  the  electrode  terminals. 

Eimac  also  announced  improvements 
in  popular  commercial  and  military 
tube  types  such  as  the  3X2500A3  and 
3X3000F1  power  triodes,  as  well  as  new 
high  vacuum  rectifiers  and  water-  and 
air-cooled  tetrodes. 

Along  with  the  new,  Eimac  featured 
products  that  have  been  performance 
proved  through  years  of  operation  in 
all  types  of  commercial  and  military 
service.  These  tubes,  of  course,  included 
the  Big  Six  of  Amateur  Radio  opera- 
tion, the  4-65A,  4-125A,  4-250A,  4-400A 
and  4X150 A  radial-beam  power  tet- 
rodes and  4E27A  radial-beam  power 
pentode. 

New  developments  and  standard  line 
tubes  shown  at  the  I.R.E.  show  repre- 
sent the  leadership  and  reliability  that 
have  made  Eimac  the  world's  largest 
manufacturer  of  transmitting  tubes.

IN   //aweif'^E.ujs  equipment 


Here   at   Harvey-Wells,   we   make   communications 
systems  for  military  and   commercial  applications, 
and  we  believe  that  Hams  too,  want  their  stations 
complete  In  every  respect.  That's  the  basic  thinking 
behind    this    new  equipment   we    are    introducing. 
The  tremendous  success  of  our  TBS-50  Bandmaster 
has  been   due   In   part  to  the  fact  that  It  can   be 
put    on    the    air    quickly    and    efficiently    because 
it  Is    a    complete    "package"    with    no    additional 
equipment  necessary. 

Our   new   T-90    Bandmaster  Transmitter   Is   also   a 
complete    "package".    It   can    be   on   the   air  five 
minutes  after  you  bring  It  home  If  you  so  desire. 
Just    plug    In    the    power    supply    and    connect  the 
antenna.    Our    new     R-9    Bandmaster    Receiver,   In 
Its    matching    case,   becomes    an    Integral    part    by 
simply  connecting  the  antenna  to  the  T-90. 

For  fixed  station  operation,  we  offer  the  APS-90 
A.C.    Power   Supply    in    a   cabinet  to    match.    (Jus> 
connect  to    115V  A.C,   plug   the   output  cable   In 
the   rear   of  the  T-90   and   you  are  ready  to   go.) 
The   R-9   Bandmaster   Receiver  has  a   built-in  A.C. 
supply.  For  mobile  operation  we  have  two  vibrator 
power  supplies,  the   VPS-  T90  for  the  transmitter, 
and   the   VPS-R9   for   the   receiver.    Both   are   con- 
vertible for  6  or  12  V  operation. 

Speakers  for  either  fixed  or  mobile  operation  are 
matched    electrically    and    physically   to    the    R-9 
Bandmaster  Receiver  to  complete  the  system.  This 
new  Bandmaster  Series  Is  a  complete  system,  en- 
gineered for  fixed,   mobile  or  portable  operation  ^ 
—  a  system  which  has  beauty  as  well  as  efficiency. 
It's  well  worth  waiting  for. 

P.S.  We  ore  still  making  the  world-famous  TBS-50  too!

MALLORY  HAM  BULLETIN 


Pi  Coupling  Networks 
are  easy  to  make  with 
Mallory  153L  Decade  Switch 


OUT 


Whenever  an  amateur  designer  tackles  the  job  of 
putting  together  a  "Pi"  antenna  coupHng  net- 
work, he  runs  into  the  problem  of  getting  a  wide 
capacitance  tuning  range  on  the  antenna  side 
of  the  circuit. 

The  usual  method  of  assembling  a  decade  group 
of  10  mica  fixed  capacitors  and  a  selector  switch 
is  not  nearly  as  siinplo  as  it  sounds.  First,  it 
requires  10  capacitors  .  .  .  which  take  a  lot  of 
space.  And  second,  getting  these  units  arranged 
into  a  compact,  short-lead  pattern  is  far  from  easy. 

Here  is  what  radio  experimenters  at  Mallorv  did 
to  lick  the  problem.  Instead  of  10-unit  decades, 
thev  built  a  capacitor  decade  with  only  four 
capacitors  .  .  .  bv  using  a  Mallory  Type  1S3L 
Switch.  Tvpe  MC  SOO  volt  mica  capacitors,  with 
values  of  100,  200.  300  and  400  mmfd.  are  con- 
nected to  the  switch  in  the  reconunended  manner. 
As  the  switch  is  rotated,  the  capacitors  are  auto- 
matically connected  in  single  and  parallel  arrange- 
ments to  provide  ten  steps  of  100  mmfd.  each, 
plus  an  "off"  position.  If  voure  not  familiar  with 
the  153L  Switch  you  can  find  a  description  in 
any  late  Mallorv  Distributor  Catalog. 

Placing   a   variable  capacitor,   with   a  range  of

INDIANAPOLIS  6       INDIANA 


about  20  to  23S  mmfd.  in  parallel  with  the 
decade  switch  provides  an  out|)ut  circuit  with  a 
smoothly  adjustable  range  from  20  to  133.^  mmfd. 
This  circuit,  as  set  up  by  Mallorv  auuileurs.  gives 
good  matching  from  most  low  power  final  ampli- 
fier stages  into  a  wide  range  of  antenna  feeds.  It 
will  be  smoothest  when  working  from  plate 
impedances  of  the  order  of  3000  to  SOOO  ohms 
into  a  50  ohm  co-ax  fed  antenna  system.  As 
drawn  here,  the  circuit  \\ill  work  well  on  all 
bands  from  3..")  through  28  megacycles. 

The  inductor  hi  nuist  be  made  adjustable  over  a 
range  from  20  to  2  or  3  microhenries,  depending 
on  the  frequency  band  and  on  the  particular 
plate  and  antenna  inq)edances.  Representative 
values  will  be  found  in  the  Radio  Amateur's 
Handbook  and  in  magazine  articles  on  "Pi" 
network  operation. 

Your  MallorA*  distributor  will  be  glad  to  show 
you  one  of  these  versatile  Capacitor  Decade 
Switches,  as  well  as  the  many  other  Mallory 
electronic  components  that  you  can  rely  upon  to 
keep  your  rig  in  top-notch  operation.  Stop  in  and 
see  him  soon,  and  put  this  idea  to  work  for 
yourself,   too!

Kit  of  6  tools 
$2. SO 

(suggested  net  price) 


New  Tool  Kit  simplifies 
cutting  of  control   and 
switch  shafts 


Shafft-Kut  Kit 


These  tools  are  especially  handy  when 
you  have  to  cut  ofi  a  shaft,  adapt  a  shaft 
and  knob  type,  or  pry  out  the  slot  in  a 
Centralab  "R"-type  Front  Fastatch  Dual 
Control.  Here's  what  you  get: 


1.  Custom-made,  hardened 
carbon -steel,    shaft  clamp 

that  holds  any  shaft  in  a 
vise,  firmly  and  without 
damage. 

2.  Fine-tooth,  high-speed 
hack  saw  blade  that  has  ex- 
tra-fine teeth  (32  per  inch) 
for  a  clean  cut. 

3.  Precision,  half-round, 
needle  file  that  is  narrow 
enough  to  get  inside  the  tu- 
bular outer  shaft  of  a  dual 
concentric. 

4.  "A"-siie  drill  that  is  just 
the  right  size  to  drill  out 
those  few  special  plastic 
knobs  so  that  they  fit  the 
inner  shaft  of  a  CRL  Fas- 
tatch dual. 

5.  AK-16  drill  stop  that 
limits  the  depth  of  cut  to 
the  exact  dimension  required. 

6.  Small  screwdriver  that 
you  can  use  to  adjust  set- 
screw  knobs,  and  to  do  many 
other  jobs. 


Ask  your  Centralab  distributor  to  show 
you  a  Centralab  Shaft-Kut  Kit.  See  if 
you  don't  agree  that  it  can  be  mighty 
useful  to  you  in  a  hundred-and-one  dif- 
ferent ways.  Then  buy  one.

Cheek  for  TVI! 


It's  not  always  easy  to  spot  points  of  superiority  among  com- 
peting products,  but  after  careful  comparison  one  out  of 
every  four  active  radio  amateurs  has  chosen  the  world  fa- 
mous Viking  II  transmitter. 

That's  why  we  say,  "Before  you  buy  .  .  .  check  for  TVI!"  ff- 
fecfively  TVI  suppressed,  the  Viking  II  leads  the  field  in  per- 
formance, signal  quality,  and  dependability.

Viking    11    Transmitter    Kit.  Complete  with  tubes, 
less  crystols,  key  and   mike    Cat.  No.    240-102 


Before  yoii  buy  your  amateur 
transmitter,  make  sure: 
Cabinet  shielding  is  complete,  metal  to 
metal  bonded  every  inch  of  the  way.  Ex- 
perience has  proven  that  even  the  small- 
est aperture  may  allow  TVI  harmonics. 
Control  shafts  are  bonded  to  the  panel 

—  otherwise  they  act  as  small  antennas 
for  harmonics. 

Meter  is  thoroughly  shielded  and  leads 
filtered — a  dangerous  area  for  harmonic 
radiation  if  not  protected. 

All  external  leads  are  carefully  filtered 

—  The  AC  line,  key  leads,  control  leads, 
power  leads  for  other  equipment — all  can 
radiate  harmonics  unless  they're  filtered 
before  they  emerge. 

Dial  apertures  are  shielded  —  Every 
opening  is  a  potential  source  of  TVI. 
All  amateur  bands  from  1 0  to  1 60  meters, 
1  35  watts  AM  phone  input,  1  80  watts  CW.  All 
stages  metered  —  instant  bandswitching — wide- 
range  pi-output  tuning.  Available  from  your

Mr.  Osborne  R.  Mc  Keraghan,  WlHRV.  in  the  running

Notes  on  the 
"Robert  Dollar"  Oscillator 

Considerable  use  is  being 
mode  of  the  circuit  shown  in 
figure  1  for  overtone  use.  Re- 
drawn as  in  figure  2  this  cir- 
cuit appears  as  a  basic  Pierce 
Oscillator  where  Ri  is  plate 
load.  Copocitor  Cz  may  be 
considered  a  blocking  copoc- 
itor, while  Ci  is  the  plote 
capacitor  providing  capocitive 
reactance  as  required  in 
Pierce  Oscillator. 

This,     for     the     moment,     neglects     the 
tuned   circuit   L-C.   Such   a  situation  occurs 
when     l-C     is     detuned     from     the     overtone 
crystal    frequency.    When    the    oscillotor    is    placed 
in    operation    under    these    conditions    Crystal    Yi 
oscillates,     as    in    any    Pierce    Oscillator,    on     its 
fundamental     mode.     Output     will     be     obtoined 
from    the    circuit   and    drive    indicated   to    succeed- 
ing   stages.    However,    the    crystal    will    he    oper- 
ating   on    its   fundamental.

THE  2  METER  LINEAR  RF  POWER  AMPLIFIER. ..a  new 
member  of  the  Gonset  Communicator  fami  ly... provides 
carrier  power  output  of  50-60  watts... when  driven  by  a 
Communicator. 

Patch  to  existing  Communicator  in  less  than  a  minute,  no  al- 
terations required.  Switching  Communicator  to  transmit  auto- 
matically activates  the  amplifier. ..including  antenna  change- 
over relay. 

Gonset  has  "Engineered  out"  tricky  adjustments.  Fool-proof, 
easy  tune  up  requires  only  observance  of  amplifier  panel  in- 
dicator in  conjunction  with  conventional  set-up  of  driving 
Communicator. 

Amplifier  uses  push-pull  826  VHF  triodes  with  forced  air 
cooling.  Power  supply  utilizes  two,  5U4GB  rectifiers  in  a 
husky,  voltage  doubling  power  supply  circuit.  Cabinet  matches, 
(style  and  size)  that  of  Communicators,  looks  (and  operates) 
well  with  other  2  meter  equipment.

Designed    essentially    to    complete    the 
new  Gonset  6  meter  Communicator  pack- 
age, the  excellent  characteristics  of  this 
new  beam  render  it  well   suited  for  gen-      ^

Consists  of  four  elements,  reflector, 
folded  dipoleand  twodirectors;  the  array 
being  largely  pre-assembled  thus  simpli- 
fying field  erection. 

A  balun  is  provided  for  balanced  feed 
and  correct  match  of  52  ohm  unbalanced 
coax  lines  to  symmetrical  folded  dipole 
with  low  VSWR. 

Forward  gain  is  approximately  10  db.

ALASKA  — SC.M,  Dave  A.  Fulton,  KL7AC;U  —  It 
appears  that  it  soon  will  be  hamfest  time  again  and  the  date 
for  the  .Alaska  Amateur  Radio  Convention  has  been  set 
for  July  22,  23,  and  24.  It  will  be  somewhere  in  the  .Anchor- 
age Area  and  just  as  soon  as  we  get  the  details  will  pass 
them  on.  AWB  reports  several  good  openings  oii  21-IMc. 
c.w.  to  the  East  Coast,  also  AWB  reports  lack  of  W  interest 
in  working  KL7s  in  the  CD  Contests.  Ws  and  VEs  just 
don't  seem  interested,  or  is  it  the  weak  signal?  We  would 
like  to  know  the  answer  to  that  one  ourselves,  Joe.  It  might 
be  why  more  KL7s  aren't  on.  DG  is  holding  radio  classes  in 
Kodiak  and  there  should  be  some  newcomers  soon  from 
that  island  city.  AGU  finally  has  the  mobile  installed  in  the 
new  vehicle  and  should  be  heard  more  often  on  75-meter 
mobile.  It  should  be  about  time  to  get  the  mobile  tuned  up. 
How  about  it,  fellow?

A  good  microphone  can  improve  your  results 
as  much  as  a  high  gain  antenna 


Ever  notice  that  two  signals  of  the  same  "S  meter"  intensity  sound  dif- 
ferently? One  is  muddy,  dull,  a  little  hard  to  read — the  sibilant  letters 
like  S  and  F  almost  alike.  The  other  signal  is  sharp,  clean  and  readable 
even  in  QRM  and  QRN — because  there's  usable  intelligence.  No  mistake 
about  the  call  or  comments. 
The  greatest  variation  is  in  the  microphone.  A  sharp  peak  adds  no  intelligibility  but 
limits  the  modulation  to  that  value.  A  peak  of,  say  6  db,  which  is  usual  in  many 
ordinary  microphones,  will  reduce  voice  power  by  HALF.  Don't  be  fooled  by  a 
microphone  that  sounds  "louder" — loudness  by  itself  is  not  a  criterion  of  perform- 
ance; quite  the  contrary  since  it  may  indicate  undesirable  peaks. 

An  E-V  microphone  with  smooth,  peak-free  response,  replacing  an  inferior  instru- 
ment, often  will  do  more  for  a  phone  signal  than  a  new  antenna  or  increased  power. 
As  a  further  plus,  of  course,  you  get  well-known  E-V  durability,  style  and  perform- 
ance. An  E-V  microphone,  to  raise  stations,  to  carry  through  a  QSO,  is  your  best 
station  investment. 


Shown  above  are  a  few  of  the  E-V  microphones  designed  for  effec- 
tive communications.  Amateur  discount  applies.

LF-601  Low  Pass  Filter 

Interference  to  TV  reception  caused  by  trans- 
missions from  a  Ham  station  can  be  caused 
by  harmonics  from  the  transmitter.  They  can 
be  greatly  reduced  or  eliminated  with  a  Bud 
LF-601  low  pass  filter.  Minimum  attenuation 
of  85  decibels  on  all  frequencies  above  54 
megacycles  and  a  minimum  of  93  decibels 
above  70  megacycles.  Can  be  used  with  52  or 
72  ohm  coax.  Cut-off  frequency  is  42  mega- 
cycles. Maximum  rejection  adjustable  from 
55  to  90  megacycles.

HF-600  High  Pass 
Filter 

Has  cut-off  frequency  at  42 
megacycles,  thus  this  filter  re- 
jects signals  from  0  to  42  megacycles.  It  is 
within  this  range  that  the  majority  of  sig- 
nals causing  interference  are  received.  Since 
there  is  no  attenuation  above  42  megacycles, 
picture  strength  or  quality  is  not  affected. 
This  unit  is  easily  attached  to  the  TV  set.

was  put  on  by  SY  and  BIP.  The  HAMS  once  again  has 
changed  its  meeting  night;  starting  in  February  the  Club 
meets  the  3rd  Fri.  night  of  each  month.  HAMS  (local  Red 
Cross  group)  participated  in  the  local  disaster  drill.  Oakland 
supposedly  was  hit  by  a  strong  earthquake  and  aU  local 
branches  of  the  Red  Cross  came  to  her  aid.  With  Admiral 
Cooke  in  charge  all  the  bay  area  cities  attended  a  meeting 
at  the  local  Jewish  Community  Center  in  San  Francisco 
and  gave  a  report  on  activity.  The  amateur  group  of  Red 
Cross  Communications  put  on  a  demonstration  of  how  they 
worked  in  time  of  disaster.  Five  mobiles  checked  in  with 
net  control  at  center,  stated  what  equipment  they  were 
using  and  their  location.  NL  acted  as  outside  net  control 
and  BVS  acted  in  charge  at  the  Community  Center.  Evi- 
dently the  demonstration  made  quite  an  impression  on  the 
group.  The  point  was  brought  ui)  that  amateurs  could  con- 
tact other  amateurs  in  disaster  places  and  obtain  all  the 
information  needed  before  the  Red  Cross  Survey  Depart- 
ment could  even  reach  the  stricken  city.  The  HAMS  use 
the  2-meter  band  for  c.d.-Red  Cross  work  and  the  Club  was 
congratulated  on  how  well  organized  it  is.  YLRCSF,  tlie 
ladies'  radio  group  of  San  Francisco,  celebrated  its  first 
birthday  by  holding  a  dinner  for  members  and  their  families. 
CEE,  Vada  Letcher,  president  of  the  National  Ladies' 
Radio  Clubs,  came  up  from  Santa  Monica  to  join  in  the 
celebration.  The  Mobileers  had  14  members  take  a  trip  to 
Yosemite  Valley.  They  had  such  a  good  time  they  decided 
to  make  Yosemite  Motorcade  a  yearly  affair  hereafter. 
Three  San  Francisco  amateurs  died  within  a  short  time  of 
each  other,  P.A,  YZL  and  ILS.  Condolences  to  their  families.

Since  1948  Hughes  Research  and  Development  Laboratories 
have  been  engaged  in  an  expanding  program  for  design, 
development  and  manufacture  of  highly  complex  radar  fire 
control  systems  for  fighter  and  interceptor  aircraft.  This 
requires  Hughes  technical  advisors  in  the  field  to  serve 
companies  and  mihtary  agencies  employing  the  equipment. 

As  one  of  these  field  engineers  you  will  become  familiar  with 
the  entire  systems  involved,  including  the  most  advanced  elec- 
tronic computers.  With  this  advantage  you  w^ill  be  ideally 
situated  to  broaden  your  experience  and  learning  more 
quickly  for  future  application  to  advanced  electronics  activ- 
ity in  either  the  military  or  the  commercial  field. 

Positions  are  available  in  the  continental  United  States  for 
married  and  single  men  under  35  years  of  age.  Overseas 
assignments  are  open  to  single  men  only. 


The  time  was  never  more 
opportune  than  now  for  becoming 
associated  with  the  field  of 
advanced  electronics.  Because  of 
military  emphasis  this  is 
the  most  rapidly  growing  and 
promising  sphere  of 
endeavor  for  the  young  electrical

a  pair  of  6146s  to  be  used  at  school  in  W7-Land.  The 
problem  is  that  1 10  volts  d.c.  is  all  that  is  available.  LSE  is 
talking  about  s.s.b.  and  a.m.  He  is  building  kw.  rigs  for

while  recuperating  from  a  severe  heart  attack,  operated  a 
75-watt  bedside  rig  on  20,  40,  and  80  meters  and  enjoyed 
meeting  old  friends  and  handling  some  traffic  to  pass  the 
time.  This  is  the  second  year  he  has  been  confined  to  a 
bedside  rig.  Jerry  says  it  renews  his  old  feehng  toward  ham 
radio.  CE  is  building  an  813  rig  so  small  it  will  go  in  a  hat  — 
a  10-gallon  hat,  that  is.  FDZ,  ADZ,  URU,  and  FJF  were

YEARS  AND  OPERATES  W3L0E  ...  IS  ASSISTANT 
MANAGER  OF  THE  ENGINEERING  DEPARTMENT 
AT  THE  WESTINGHOUSE  ELECTRONICS  DIVISION. 


WITH   AH   IMPORTAHT  MESSAGE 
FOR   ALL   ELECTROHIC   EHGIHEERS! 


You  may  have  heard  Bob  Cheek 
on  the  DX  bands  during  the  re- 
cent DX  contest.  Bob  is  a  ham 
of  23  years  standing,  and  is 
recognized  as  an  outstanding 
DX  operator,  both  phone  and 
CW.  Like  many  hams,  Bob  finds 
that  his  "rig"  is  relaxing  and 
educational  ...  and  as  stimu- 
lating as  his  work  on  advanced 
development  projects  at  the 
Westinghouse  Electronics  Divi- 
sion. 


Can  a  job  be  as  interesting  as 
a  hobby?  Bob  says  it  can!  "At 
Westinghouse,"  he  contends, 
"the  combination  of  profes- 
sional surroundings,  creative 
freedom  and  challenging  'proj- 
ects of  tomorrow'  has  put  me 
in  a  real  'engineer's  heaven'! 
In  addition,  the  income  and 
employe  benefits,  fine  suburban 
living  conditions,  and  so  forth 
have  helped  both  myself  and 
my  family  achieve  many  of  our 


lifetime  goals  while  we  are  still 
young  enough  to  enjoy  them!" 
For  the  expansion  of  work  on 
the  interesting  projects  men- 
tioned by  Bob  Cheek,  Westing- 
house needs  still  more  experi- 
enced electronics  engineers.

BRITISH  COLUMBIA  — SCM,  Peter  Mclntyre, 
VE7JT  —  You  didn't  see  anything  in  your  QST  column  for 
January  since  "you  no  write,  me  no  type."  The  hams  at 
Dawson  Creek  are  in  full  swing  with  emergency  work  in 
conjunction  with  the  c.d.  and  the  RCMP  and  the  fellows 
at  Kelowna  were  there  with  mobile  and  emergency  gear 
when  a  hunter  was  lost  in  the  mountains.  Welcome  to  two 
new  ECs,  ADV  in  District  6,  and  AHJ,  of  Terrace,  in  Dis- 
trict 14.  District  2  on  Vancouver  Island  now  boasts  8  mo- 
biles, namely  ALL,  BF,  US,  GP,  DH,  AOG,  ACC,  and  PN. 
ASR,  as  RN7  manager,  reports  little  activity  because  of 
poor  band  conditions.  Congrats  to  AAH  and  his  XYL  on 
the  birth  of  a  jr.  operator.  Congrats  to  AUF  and  AQW 
and  QC,  who  have  been  carrying  the  load  on  the  AREC 
Net  during  the  poor  band  conditions.  If  any  VE5s  or  VE6s 
read  tliis  section  we  would  appreciate  their  cooperation  on 
3755  kc.  at  AREC  Net  time.  We  know  the  frequency  is  not 
exclusively  ours  but  think  of  all  the  free  channels  open 
during  our  hour  of  net  time.  We  respect  their  net  frequency 
of  3765  kc.  so  give  a  listen,  fellows,  before  you  start  testing 
and  bellowing.  I  hear  the  BCERARC  is  cooking  up  some

Symbols 

(Cnn Untied  from  page  17) 

zigzag  syinl)()l  lor  inductance  .''o  (hat  it  could  Ix- 
used  for  resistance  and  the  communication  work- 
ers gave  up  the  parallel  lines  for  capacitance  so 
it  could  be  retained  as  a  contact  sj^mbol. 

Obviouslj^,  the  power  engineers  could  not  im- 
mediately use  the  zigzag  symbol  for  resistance 
because  it  already  meant  an  inductance  to  them; 
so  the  two  e.xisting  symbols  for  resistance  had  to 
be  retained. 

The  communication  inductance  symbol  is 
complicated  and  therefore  expensive  to  draw 
with  a  drafting  guide,  and  the  small  loops  tend 
to  fill  with  ink  when  a  diagram  is  reduced  to 
small  size.  The  simpler  form  that  omits  these 
loops  was  accepted  as  a  more  practical  alterna- 
tive S3-mbol. 

Both  groups  gave  up  their  capacitance  symbols 
because  the  communication  version  was  too 
much  like  the  power  open  contacts  and  the  power 
symbol  had  the  same  drafting  and  reduction 
faults  as  the  communication  inductance.  There 
was  considerable  unhappiness  over  the  compro- 
mise symbol  that  uses  one  curved  and  one  straight 
line  but  it  was  the  best  that  was  thought  of  at 
the  time,  or  since  then. 

Agreement  could  not  be  reached  on  a  single 
symbol  for  electric  contacts  because  the  power 
group  must  have  a  verj^  clear  distinction  between 
open  and  closed  contacts  and  the  communication 
group  must  be  able  to  show  a  large  number  of 
contacts  in  a  single  compact  assemblj^  as  is  often 
required  in  telephone  work.  Both  existing  symbols 
were  therefore  retained. 

Acceptance  of  the  idea  that  we  are  using 
symbols,  rather  than  pictograms  of  actual  pieces 
of  equipment,  means  that  there  need  be  no  top 
or  bottom  for  a  symbol  as  there  might  be  for  a 
picture.  Thus,  a  ground  symbol  maj^  point 
toward  the  top  or  side  of  the  drawing  and  the 
same  is  true  of  an  antenna  symbol,  which  might 
point  toward  the  bottom  of  the  sheet. 

Capacitance  and  Capacitors 

If  you  have  stumbled  over  "capacitance"  be- 
cause 3'ou  are  accustomed  to  "capacity,"  please 
note  that  the  unfamiliar  form  was  used  with 
malice  aforethought.  This  is  one  technical  matter 
in  which  the  amateur  has  not  been  showing  the 
way  to  the  professional. 

There  are  three  basic  elements:  resistance,  in- 
ductance, and  capacitance;  and  they  are  pro- 
vided by  resistors,  inductors,  and  capacitors. 

Strictly  speaking,  capacity  is  the  abilitj'  of  a 
device  to  do  work,  and  we  should  speak  of  the 
capacity  of  a  vacuum  tube  as  being  so  many 
watts.  Its  interelectrode  capacitance  will,  of 
course,  be  stated  in  micromicrofarads  or  pico- 
farads, which  are  the  same  things. 

A  condenser,  again  strictly  speaking,  is  a  de- 
vice used  with  steam  engines  to  condense  the 
e-xhaust  steam  into  hot  water  that  is  pumped 
back  into  the  boiler.  This  saves  fuel  in  heating

connected  between  Pins  6  and  7,  and  a  plate 
meter  or  jumper  between  Pins  6  and  8. 

A  modulator  of  simple  design  that  can  be 
adapted  readily  to  use  with  this  transmitter 
was  shown  in  QST  for  December,  1954,  page  29. 
A  6L6  can  be  substituted  for  the  6V6GT  shown 
in  the  original,  if  more  audio  power  is  required. 

Power  output  at  300  volts  is  about  10  watts, 
which  is  enough  to  do  interesting  work  on  220 
Mc.  if  a  good  antenna  system  is  used.  Antenna 
ideas  can  be  found  in  December,  1953,  QST, 
or  in  any  recent  edition  of  either  The  Radio 
Amateur's  Handbook,  or  the  ARRL  Antenna 
Book.  The  transmitter  may  also  be  used  as  a 
source  of  driving  power  for  any  of  the  larger 
dual  tetrodes,  such  as  the  6524,  6252,  5894  or 
9903.  The  first  two  will  take  up  to  50  watts 
input  on  220  Mc,  the  latter  two  up  to  100 
watts  or  more.

same  length,  and  tapped  at  the  exact  center,  so 
that  each  pair  of  driven  elements  would  be  in 
phase.  The  whole  system  was  then  resonated  with 
a  single  shorted  stub  approximately  40  inches 
long.  The  balun  taps  were  about  53^  inches 
up  from  the  short  in  this  case.  The  positions  for 
the  short  and  the  taps  were  found  by  using  a 
temporary  stub  about  four  feet  long,  sliding 
the  shorting  bar  and  the  taps  until  maximum 
forward  power  and  minimum  reflected  power 
were  indicated  on  the  s.w.r.  meter. 

A  6-element  array  for  222  Mc.  has  driven 
elements  20  inches  long,  with  directors  25K 
inches  long  of  34-inch  thin-walled  brass  tubing. 
End  insulators  of  3^-inch  o.d.  fiber  bakelite 
mount  in  a  li^s-inch  square  wooden  boom  3^ 
feet  long.  The  directors  are  4  inches  in  front  of  the 
driven  elements.  The  phasing  line  of  TV  ladder 
line  is  40  inches,  with  a  263'^-inch  tuning  stub  at 
the  center.  When  300-ohm  tubular-type  line  is 
employed  it  is  tapped  23^  inches  up  from  the 
short.  Metal  construction  would  have  been  satis- 
factory, but  in  view  of  the  small  size,  wood  was 
used. 

The  simple  6-element  array  of  Fig.  2  offers 
good  possibilities  for  portable  operation.  A  gain 
of  10  db.  or  more  over  a  car  antenna  of  the 
same  height  (more  if  a  few  feet  of  mast  is  added) 
can  mean  a  tremendous  improvement  on  long- 
distance contacts.  Either  the  6-  or  the  12-element 
beam  is  light  in  weight  and  of  low  wind  resistance 
and  can  be  handled  readily  by  one  man.  The 
horizontal  directivity  pattern  is  the  same  with 
l)oth  beams  (when  vertical  polarization  is  used) 
but  the  gain  of  the  12-element  array  is  increased 
by  3  db.  because  of  the  lowered  vertical  angle  of 
radiation.

AMERICAN 
CANCER  SOCIETY  i 


Applying  the  Principle  to 
Long  Yagi  Arrays 

A  conventional  6-element  Yagi  with  one  re- 
flector and  four  directors  gave  a  measured  gain 
of  9  db.  over  the  reference  dipole.  A  special 
Yagi  with  two  shortened  driven  elements  and 
four  directors  (no  reflector)  gave  10-db.  gain  at 
145  Mc.  Apparently,  this  design  can  be  used 
on  Yagi  antennas  to  give  better  performance, 
and  preliminary  calculations  indicate  that  a 
single  long  Yagi  can  be  tuned  up  to  operate  over 
one  megacycle  of  the  2-meter  band  with  a  forward 
gain  of  17  db.  This  would  involve  a  boom  length 
of  some  24  feet,  however.  Experimentally,  it 
may  be  possible  to  better  this  figure  for  a  very 
narrow  bandwidth.  This  offers  interesting  possi- 
bilities for  long-distance  2-meter  c.w.  communica- 
tion, say,  between  144.0  and  144.2  Mc,  with 
selective  receivers  and  a  few  hundred  watts  of 
transmitter  output.

With  this  self-contained  ham  station  you  built

reliable,  low-power  c.w.  station  on  40  and  80  — 
and  you  can  have  plenty  of  fun  with  it  from  your 
home  station,  out  in  a  boat,  at  the  beach,  climb- 
ing a  mountain,  or  whatever. 

I  wish  to  acknowledge  the  helpful  sugges- 
tions of  the  late  Walter  Bradley,  WlFWH,  of 
ARRL,  and  the  assistance  of  my  11-year-old 
son,  WNlBRS,  in  assembling  the  rig  and  manning 
the  home  station  during  tests.

was  wound  in  the  form  of  3  pies  on  a  1-inch- 
diameter  bakelite  rod.  Commercially-available 
chokes  could  be  used  and  turns  removed  to  give 
the  right  inductance  value.  For  Qs  much  different 
than  specified,  some  adjustment  of  the  feed-back 
condensers  C2  and  C^  and  the  anode  load  re- 
sistance will  be  necessary.  The  oscillator  was 
built  in  a  3  X  4  X  5-inch  metal  utility  box  with 
the  tube  mounted  on  one  side.  The  cathode  choke 
coil  was  pi-wound  on  a  small  form.  This  choke 
coil  is,  however,  readily  obtainable  from  commer- 
cial stock.  The  oscillator  tunes  from  20.4  to  23 
kc.  The  low-frequency  limit  is  set  by  the  fixed 
bandset  condenser. 

Power  Supply 

Although  an  electronically-regulated  power 
supply  was  used,  it  is  not  absolutely  necessary. 
It  does,  however,  provide  a  power  source  having 
a  low  output  impedance  at  20  kc,  and  thus  lends 
to  the  over-all  stability  of  the  amplifier.  The 
voltages  are  made  available  for  use  with  external 
audio  filters  and  clippers  through  an  octal  plug. 
It  is  convenient  to  be  able  to  draw  current  from 
the  power  supply  without  upsetting  the  amplifier 
supply  voltages. 


5-Band  Antenna  Coupler 

(Continued  from  page  Jfi) 

the  feedline  plus  antenna,  not  feedline  plus  half 
the  antenna. 

In  many  instances  it  is  more  convenient  to  put 
up  a  Zepp  antenna  than  a  center-fed  one.  If, 
however,  there  is  only  room  for  a  66-foot  antenna 
(half  wavelength  at  7  Mc.)  and  80-meter  opera- 
tion is  desired,  the  feeders  can  be  tied  together  in 
the  shack  and  connected  to  one  of  the  antenna 
terminals  of  the  coupler.  If  it  will  work  with  a 
parallel  connection,  fine;  if  it  won't,  a  series  con- 
nection can  be  tried,  with  the  other  antenna 
terminal  of  the  coupler  connected  to  ground.  An 
antenna  worked  this  way  is  a  "random"  length 
of  wire,  and  consequently,  the  same  tuning  pro- 
cedure applies  to  a  piece  of  wire  that  is  actually 
a  random  length  and  doesn't  have  any  feedline. 
The  trouble  with  antennas  lacking  a  true  feed- 
line  is  that  they  are  sometimes  responsible  for 
"r.f.  around  the  shack,"  as  evidenced  by  r.f.  on 
microphones  and  cabinets. 

HaTtaonics 

One  last  bit  of  information  worth  passing  along 
to  the  newcomer  who  may  not  know  one  of  the 
values  of  using  a  coupler:  As  many  amateurs 
have  found  to  their  sorrow,  harmonics  of  their 
transmitted  signal  can  get  them  into  trouble  with 
the  FCC.  The  use  of  a  link-coupled  antenna 
coupler  provides  considerable  attenuation  of  har- 
monics, usually  enough  to  keep  them  from  inter- 
fering with  other  services.  And  if  one  is  experi- 
encing TVI  caused  by  harmonics,  the  coax  Unk 
line  between  the  transmitter  and  the  coupler 
furnishes  an  ideal  spot  for  the  installation  of  a 
low-pass  filter.

EDITION 


HIGHLIGHTS  OF  THE  1955  HANDBOOK: 

The  high-frequency  chapter  Includes  many  new  units  incorporating  such 
features  as  continuous  (multiband)  tuning  units,  pi-section  tanks  and  clamp- 
tube  protective  circuits.  V.h.f.  material  has  been  extensively  changed  to 
improve  clarity  and  take  advantage  of  techniques  developed  as  a  result 
of  greater  occupancy  of  this  portion  of  the  radio  spectrum.  The  v.h.f. 
transmitter  chapter  includes  equipment  using  tubes  developed  in  the  past 
year.  The  section  on  vacuum  tubes  and  semiconductors  has  been  enlarged 
to  accommodate  numerous  new  tubes,  crystal  diodes  and  transistors;  a 
complete  listing  of  electrostatic  cathode-ray  tubes  forms  a  part  of  the 
tube  tables.  The  1955  edition  is  packed  with  information  useful  to  the 
amateur  and  professional  alike!

on  80  meters.  South  Sandwich  hamming  is  nil  with  no 
prospects  in  sight,  but  South  Georgia  may  see  a  new  VPS 
or   two   firing  up  shortly.   VPSAY's   first   QSO   from   the 

Falklands  was  with  W4YHD W3AXT  of  DXer- 

ama  fame  points  out  that  7-Mc.  c.w.  candidates  LUs  IXP 
9YG  and  PY7RY  represent  very  rare  areas  toward  South 
American  DX  certificate  awards. 

Hereabouts  —  We  regret  to  note  the  passing  of  invet- 
erate DXers  nC2JR  and  YSIRP.  HC2JR's  radiotelephone 
DX  and  DXpeditionary  (Galapagos  Isles)  achievements 
are  all  the  more  remarkable  in  view  of  his  confinement  to  a 
wheel  chair  for  many  years  ._._._  Servicmg  of  Navassa 
Light  now  is  done  out  of  Miami  instead  of  San  Juan,  P.R. 
KP4KD   reports   that   this   change    puts   the   quietus   on 

KP4TF's  anticipated  KC4  lark Huge  joint  meets 

of  NCDXC-SCDXC  and  FRC-PVRC  outfits  Uvened  up 
the  wintry  DX  scene.  Both  affairs  featured  the  appearances 
of  various  well-known  DX  personages  and  many  yards  of 
yarn  were  spun  to  the  enjoyment  and  edification  of  all  who 

attended  . VP7NG,  who  has  rolled  up  over  1400 

QSOs  with  some  78  countries  in  just  four  months  of  Ba- 
hamas-style hamming,  is  coaching  FG7XB  on  the  finer 
points  of  the  art.  Glen  also  will  provide  Antoine  with  an 
ample  stock  of  QSLs.  VP7NG  will  remain  on  the  air  for 

another  six  months  or  so ._  Since  November,  1945, 

KP4KD  has  knocked  off  different  DX  stations  at  a  rate  of 

shghtly  less  than  one  a  day  —  a  2912  total .  _  First 

ticketed  as  9AXS  in  '23,  K6ENX  has  held  numerous  calls 
including  Ws  3EHT  6NHC  0MWK  and  XU8MI.  As 
XUSMI  m  Shanghai,  1939-1940,  Otto's  most  memorable 
QSOs  were  with  VP5PZ  and  W2BHW  (now  W8BHW)  on  7 
Mc.  Now  retired  after  27  years  of  Navy  service,  K6ENX  is 

hot  on  the  DXCC  trail WIATE,   radiotelephone 

DX  pundit  in  spades,  becomes  a  Jersey  W2  and  doubtle.ss 
will  try  his  hand  at  a  southern  antenna  plantation.

6  GOOD  REASONS 

WHY  you  SHOULD 

OWN  ONE,  NOW/ 

1.  It  actually  costs  LESS  to  own  the  best! 

Subtract  the  traditionally  high  resale  value 
of  Collins  equipment  from  its  sensational 
low  price,  and  you'll  see  how  little  it  really 
costs  per  year  to  have  the  "Cadillac  of  the 
Amateur  World." 

2.  It's  as  new  as  tomorrow!  The  advanced 
engineering  of  Collins  makes  the  KWS-1 
the  ultimate  in  the  modern  mode  of  trans- 
mission—SSB-for  many  years  to  come. 

3.  It's  a  complete  KW  transmitter!  VFO 
Exciter,  VOX  and  push-talk  control,  blocked 
grid  CW  keying,  regular  AM,  load  matching 
output  network,  tubes,  etc.  are  all  included 
in  the  low,  low  total  price  of  only  $1,995. 
Just  plug  in  and  operate! 

4.  I  give  you  bigger  allowances  for  your  old 
gear!  Shop  around-l'll  be  glad  to  top  any 
deal,  no  matter  how  crazy! 

5.  You  need  no  money  now!  On  the  Harrison 
Easy  Pay  Plan,  your  present  transmitter  will 
usually  cover  the  down  payment,  and  you  can 
spread  the  balance  over  TWO  YEARS,  while 
you  are  having  the  fun  of  using  your  Collins. 
(Everything  is  completely  confidential.) 

6.  You  only  live  once-so,  why  not  enjoy  the 
best!

New 
Edition! 


Hot  off  the  presses  of  Rand  Mc- 
Nolly  comes  this  1955  edition  of 
the  ARRL  World  Map.  Loaded  with 
changes  that  bring  our  "ham 
world"  right  up  to  the  minute! 

No  active  amateur  can  afford  to  be 
without  one  of  these  popular  and 
useful  adjuncts  to  good  operating. 
Here  is  why  the  ARRL  World  Map 
is  such  a  favorite: 


As  soon  as  you  hear  a  DX  station  you  can  see 
exactly  where  he  is — the  country  prefixes  are  not 
just  listed  in  the  marginal  index;  they're  printed 
on  the  countries,  themselves.  You  can  tell  his 
direction  from  you,  and  his  distance.  There's  no 
question  about  which  continent  he's  in  —  boundaries 
of  the  six  continents  are  plainly  marked. 


V 


The  time  zones  are  plainly  marked,  too.  Call  areas 
of  thirteen  countries  are  shown.  Principal  cities  ore 
designated.  There's  a  scale  of  miles,  another  of 
kilometers.  Printed  on  heavy  map  paper  measuring 
40"  wide  x  30"  high,  in  8  colors  that  really  stand 
out,  this  new  ARRL  World  Map  is  easily  read  from 
your  operating  position.

522  to  220  Mc,  using  the  new  6524  in  the  output  stage. 
Delivers  considerably  more  output  than  with  832A. 

W7JHX,  Port  Orchard.  Wash.  —  Built  phase-modulation 
exciter  described  by  WIVLH  in  .\ugust,  1954,  QST,  and 
f.m.  adapter  for  receiver.  Checks  with  W7UVH,  Olympia, 
who  also  has  one  of  the  exciters,  show  excellent  results  in 
comparison  with  a.m.  Activity  in  V.H.F.  SB  best  ever,  but 
some  scores  low  because  of  polarization  problem.  Switch  to 
horizontal  getting  under  way  in  Paget  Sound  area. 

W7JRG,  Billings,  Mont.  —  50-Mc.  band  open  to  W6  for 
at  least  three  hours  Jan.  29th.  Heard  W6s  BWG  KQO  ABN 
NLZ  and  ILW.  Abandoning  s.s.b.  on  50  Mc.  after  two  years 
because  of  lack  of  favorable  results.  Too  many  operators  on 
6  do  not  recognize  s.s.b.  for  what  it  is,  and  therefore  make 
no  attempt  to  tune  it  in  properly.  Inserted  carrier  method 
inefficient.  Will  be  back  on  with  a.m.  rig  essentially  the  same 
power  as  used  so  successfully  from  Sheridan,  Wyo.,  some 
years  back. 

W8WRN,  Columbus,  Ohio  —  New  stations  coming  on  144 
Mc.  all  the  time.  New  activity  in  Zanes\'ille  reported  bv 
W8JWV,  and  in  Chillicothe  by  W8CSN.  Interest  in  220 
Mc.  also  improving,  with  W8LGI  and  W8WRN  looking  for 
skeds  on  that  band. 

W9DRN.  Des  Plaines.  III.  —  Had  first  crystal-controlled 
QSO  on  432  Mc.  .Jan.  31st,  after  completing  crystal-con- 
trolled converter.  Uses  6.\N4  r.f.  stage,  6AM4  grounded- 
grid  mixer,  6BK7  50-Mc.  i.f.  amplifier,  into  S-36.  Trans- 
mitter uses  4X150.\  doubler  from  220-Mc.  rig,  with  fre- 
quency of  latter  brought  down  to  216  Mc.  Work  W9AGM, 
Chicago,  regularly.  W9ZQT  and  W9EFD  also  on  432  Mc. 

W9KQK,  Elmhurst,  //L  —  Experimenting  with  6AJ,  F, 
M,  and  N4  tubes  on  1215  Mc. 

W0QMF,  Perryville,  Mo.  —  W0s  LMK  DFK  RUF  RTO 
QMF,  and  W9s  PMN  and  KH  in  process  of  organizing  2- 
meter  net.  .\lso  experimenting  with  duplex  operation. 


When  W5QNK  broke  in  on  W5FA0  and 
W5RRL  on  75  meters,  it  became  a  real  Baptist 
pastor's  conference.  W5QNK  is  pastor  of  the 
First  Baptist  Church,  Chelsea,  Okla. ;  W5FA0  is 
pastor  of  the  First  Baptist  Church,  Vernon, 
Te.x. ;  and  W5RRL  is  pastor  of  the  East  Paris 
Baptist  Church,  Paris,  Tex. 


When  W6HSZ  goes  on  the  air,  strange  things 
happen  to  his  bath  tub.  It  seems  that  it  resonates 
around  75  meters.  Whenever  he's  on  'phone  with 
his  kw.,  the  bather,  if  there  is  one  at  the  time, 
gets  the  surprise  of  a  lifetime!  More  than  once 
his  signals  have  been  modulated  by  a  feminine 
scream.  He  plans  to  let  the  BTI  (bath  tub  inter- 
ference) stay  as  is  —  too  much  fun !  —  K6BSW

Electronic-Key  Manipulator

ease  of  operating,  while  still  simple  and  within 
the  ability  of  the  average  amateur  to  build.  The 
design  arrived  at  is  presented  here,  and  after 
some  experimenting  with  the  completed  key  for 
the  correct  adjustment,  this  design  has  stood  up 
for  a  couple  of  years  now. 

An  Army  surplus  Model  J-36  key  is  the  basis 
for  the  key  built  here.  When  revamping  this 
model  Vibroplex  the  staff  support  structure  was 
turned  180  degrees  from  its  original  position. 
Two  new  holes  were  drilled  in  the  base  to  match 
the  mounting  holes.  Two  more  holes  were  drilled 
at  the  opposite  end  to  mount  the  posts  for  the 
dot  and  dash  contacts.  As  a  rule  some  ^-inch 
stock  can  be  found  in  the  shack  and  posts  made 
as  required.  These  two  posts  are  insulated  from 
the  base  and  wires  are  connected  to  them.  The 
third  or  common  wire  is  connected  at  the  mount- 
ing screw  of  the  staff  support  structure.  Be  sure 
that  the  resistance  checks  at  infinity  on  an  ohm- 
meter  or  trouble  may  result  in  the  time-constant 
circuits  of  the  electronic  key.  The  three  wires 
are  connected  to  a  microphone  plug. 

The  arm  or  reed  is  cut  from  a  piece  of  duralu- 
min. It  is  stiff  and  springy  —  the  sort  used  in 
aircraft  construction  and  obtainable  from  a 
war-surplus  store.  Do  not  use  soft  aluminum 
as  it  is  too  easily  bent.  A  steel  reed  will  be  too 
heavy  and  will  cause  undue  vibration,  since  the 
reed  has  to  be  highly  damped ;  for  the  same  reason, 
keep  the  weight  to  a  minimum  at  both  ends. 

On  the  contact  end  a  small  hole  is  drilled 
to  match  the  contact  posts  and  a  piece  of  silver 
or  contact  material  is  forced  or  wedged  in  and 
left  extending  a  bit  to  ensure  a  good  contact  at 
the  points.  The  hole  for  the  staff  is  drilled  a 
thousandth  smaller  and  the  staff  is  pressed  in. 
If  a  drill  press  is  available,  the  following  is  a 
method  of  assuring  a  good  fit:  Clamp  the  reed  in 
the  drill  press  vise  and  with  a  drill  ten  thou- 
sandths smaller  than  the  finished  hole  drill  with  a 
fast  speed  and  easy  feed.  Every  3^  inch  or  so 
withdraw  the  drill  and  clean  off  the  chips.  Use  a 
thread-cutting  oil  if  possible.  After  the  first  hole 
is  drilled,  redrill  with  the  finish  drill.  Leave  the 
reed  in  the  drill  press  vise  and  chuck  the  staff 
in  the  drill  press;  then  press  the  staff  in  to  the 
desired  depth.  A  good  hardware  store  will  be 
glad  to  measure  the  staff  with  a  micrometer 
and  furnish  drills  of  the  right  size.  Also,  while 
at  the  hardware  store,  buy  a  3^-inch  center  drill 
and  use  it  to  true  up  the  tapered  bearings  of  the

support.  Also  true  the  staff  bearing  surfaces  if 
worn.  Sloppy  motion  must  be  kept  to  a  minimum, 
because  tolerances  are  close. 

The  springs  which  act  against  the  reed  were 
purchased  in  an  auto  parts  store  and  although 
they  are  only  about  3^  inch  in  diameter  they  are 
very  stiff  and  it  is  difficult  to  compress  them 
between  your  fingers.  Buy  the  stiffest  spring 
possible  in  that  size. 

We  are  all  different  in  our  individual  tastes, 
so  thought  has  been  given  to  meet  as  many 
fists  as  possible.  The  present  design,  I  feel, 
will  meet  the  requirements  of  a  fast  operator  with 
a  light  touch.  A  slower  operator  or  a  person  with 
a  heavy  hand  who  likes  a  lot  of  swing  will  need 
to  move  the  two  spring-supporting  posts  about 
%  inch  nearer  the  fulcrum  of  the  key,  as  well  as 
to  use  a  spring  of  lighter  tension.  However,  be- 
tween the  two  positions  and  different  springs  I 
believe  most  conditions  can  be  reached.  The 
contacts  as  shown  can  be  adjusted  to  a  very  few 
thousandths  of  an  inch  and  the  paddle  only  re- 
quires a  whisper  to  move,  but  still  the  reed  will 
center  each  time  with  no  vibration. 

The  two  adjusting  screws  near  the  paddle  are 
there  for  the  sole  purpose  of  preventing  damage 
to  the  reed  from  a  person  who  has  a  heavy  touch, 
or  takes  his  wrath  out  on  the  bug  instead  of 
himself.  As  QST  mentioned,  adapt  yourself  to  the 
bug  and  let  it  set  the  pace  —  you  will  never  make 
it  otherwise. 


Correspondence 

(Continued  from  page  52) 
entitled  Historic  Towns  of  the  Connecticut  River  Valley, 
published  in  1906.  I  ventured  no  further  than  page  7  which 
discussed  the  five  Indian  tribes  of  the  Connecticut  Valley, 
one  of  which  was  the  Podunk  tribe  situated  at  what  is  now 
East  Hartford.  A  very  enlightening  discussion,  I  felt,  and 
a  very  subtle  explanation  of  the  "Podunk  Hollow  Radio 
Club." 

Hats  off  to  all  of  you  of  the  "Hollow"  (despite  your  being 
in  West  Hartford)  for  your  knowledge  of  Connecticut 
history  —  and  to  Gil  for  his  portrayal  of  the  club.

DX  RCC 

1223  Ninth  Ave.,  South 
Escanaba,  Mich. 
Editor,  QST: 

With  regard  to  "Tips  on  Working  DX"  in  the  February 
issue,  I  should  like  to  voice  a  small  objection  —  in  part. 
I  realize  that  rare  DX  should  be  treated  accordingly  and  all 
lengthy  QSOs  ought  to  be  eliminated  so  that  as  many  as 
possible  may  benefit  from  working  the  particular  station. 

However,  in  general,  DX  contacts  can  often  contribute 
greatly  to  the  amateur  in  many  important  ways  if  longer 
rag-chewing  is  made  possible  through  favorable  conditions, 
etc.  The  promotion  of  international  goodwill  and  the  ex- 
change of  common  knowledge,  operating  and  construction 
hints,  everyday  comment  about  topics  of  mutual  interest, 
all  provide  one  of  the  most  rewarding  aspects  of  amateur 
radio.  Our  DX  contest  is  the  time  for  the  quickest  QSOs,  of 
course,  and  I  am  convinced  that  at  other  times,  when  pos- 
sible, a  more  extended,  friendly  contact  will  be  of  great 
benefit  to  both  parties  concerned. 

.^s  a  high-school  instructor  of  social  science,  I  have  de- 
rived considerable  value  through  the  interchange  of  ideas 
and  concepts  through  the  medium  of  amateur  radio,  and 
lately  have  become  very  much  aware  of  the  possibilities  on  a 
truly  international  scale.

logical  conclusion: 

Code:  A  dot  plus  a  dash  equals  "A"  (     )  Yes  (     )  No 
L.\w:   You   must   have   a  license  before   you   transmit.

Theory:  Ohms  and  volts  are  different  (     )  Yes  (     )  No 
Practical:  Do  you  have  $2500  to  invest  in  a  factory-

Do  you  intend  to  have  an  electrician  install  this  rig? 
(     )  Yes  (     )  No 

If  the  answers  to  the  above  questions  are  "yes,"  what

NO  RECIPROCITY 

233  Appleton  St. 
Lowell,  Mass. 
Editor,  QST: 

Most  of  us  hams  eagerly  devour  a  QST  yarn  spun  by  tliat 
Prince  of  Hamdom,  the  DX-peditioner,  who,  though  the 
W  pile-ups  were  rougher  than  a  stucco  bathtub,  endeared 
himself  more  than  somewhat  to  the  DX  fanciers  among  us 
by  his  generous  provision  of  wall  insulation. 

If  verbose,  he  will  majestically  expound  on  all  subjects 
from  how  his  rig  loaded  to  the  exotic  native  remedy  for 
snakebite  and  how  to  obtain  same. 

Certainly  though  he  will  explain  how  he  came  to  be  there. 
Disregarding  his  personal  problems  and  those  of  transport, 
we  read  that  some  beneficent  foreign  authority  gave  him 
permission  to  operate. 

As  we  avidly  read  his  tale  does  it  occur  to  us  that  under 
our  present  ham  regulations  the  turnabout  which  is  fair 
play  simply  cannot  occur?  We  find  that,  except  in  the  case 
of  Canadian  hams,  operation  is  barred  to  all  but  citizens. 

Among  us  there  must  reside  scores,  if  not  hundreds,  of 
responsible  businessmen,  students  and  scientists,  whose 
keys  are  gatliering  rust  because  of  these  one-sided  regula- 
tions. The  "Passport  Ham"  suffers  but  these  provisions 
handicap  us  also  in  negotiations  for  permission  to  fire  up  on 
foreign  soil. 

Contrary  arguments  based  on  "security  reasons"  are 
not  valid  as  with  proper  screening  our  present  leaky  security 
net  would  not  be  enlarged  in  gauge. 

"  Send  me  your  hungry,  your  stormtossed,  your  huddled 
masses,  etc."  does  not  seem  to  apply  to  the  case  of  the  visit- 
ing ham.

QRP  MOVEMENT 

St.  Bride's  Presbytery 
Cowdenbeath,  Fifeshire 
Scotland 
Editor,  QST: 

I  wonder  if  the  ARRL  would  be  prepared  to  initiate  a 
QRP  movement  amongst  hams.  When  we  look  at  conditions 
on  the  ham  bands  today,  it  seems  to  me  that  it  will  only  be 
by  a  return  to  (say)  a  maximum  of  1.50  watts  that  order  is 
going  to  be  restored. 

If  some  of  the  W  stations  had  their  QTH  here  in  G-land 
and  could  listen  to  the  14-Mc.  band  when  the  DL4  stations 
are  in  full  swing  with  their  BC-610s  and  ET-4336s,  they 
would  see  my  point  of  view.  To  overcome  these,  some  of  the 
Continentals  are  jacking  up  their  power,  and  the  result  is 
sheer  bedlam.  My  present  reaction  is  to  trade  in  my  equip- 
ment for  a  camera  or  butterfly-catching  equipment  since 
DX  work  is  out  of  the  question  with  high-powered  DLs  and 
high-powered  (and  often  badly  modulated)  Continentals. 
What  will  hapiien  if  the  1-kw.  transmitter  ever  becomes 
standard  equipment.  Well,  my  imagination  boggles  at  the 
thought.  When  chasing  the  DX,  could  not  such  stations 
reduce  power  and  thereby  show  some  consideration  for 
those  whose  power  is  limited  by  law? 

To  me,  this  tendency  to  increase  power  will  eventually 
destroy  the  true  amateur  spirit.  Instead  of  a  real  DXer, 
experimenting  and  building  his  own,  in  a  few  years'  time 
he'll  be  forced  to  spend,  e.g.,  $3850.00  for  a  1-kw.  trans- 
mitter and  $1075.00  for  his  receiver.  If  he  cannot  afford  to

SWL  REPORT 

Union  &  Stony  Point  Rd. 
Rochester  11,  New  York 
Editor,  QST: 

Last  year  I  received  over  500  SWL  cards.  Other  stations 
with  greater  operating  hours  have  accumulated  a  greater 
total  than  this.  I  do  not  disapprove  of  this  practice  but 
wish  to  encourage  the  reporting  in  the  right  direction. 

The  average  SWL,  and  future  amateur,  picks  out  easily 
readable  signals  within  the  popular  'phone  bands  and  sends 
a  card.  The  operator  at  the  other  end  is  well  aware  that  he 
is  getting  out  both  through  actual  contacts  and  the  deluge 
of  SWL  cards.  Why  doesn't  the  short-wave  listener  dig  down 
under  and  pick  out  the  weak  signals?  Likewise,  as  a  poten- 
tialamateur,  he  should  spend  time  listening  in  the  c.w.  bands. 

The  low-power  'phone  or  c.w.  station  will  appreciate  that 
SWL  card  far  more  than  one  of  the  high-power  boys  and 
the  chance  of  receiving  a  reply  is  far  greater.

Receiver  Hints  for  V.H.F. 

(Continued  from  page  37) 

approximate  that  of  the  bandspread  dial.  On 
most  receivers  this  gadget  is  helpful  for  applica- 
tions in  addition  to  use  with  v.h.f.  converters.  It 
makes  fishing  for  stations  outside  the  ham  bands 
more  enjoyable,  and  it  preserves  the  calibration 
of  the  general-coverage  dial,  which  is  upset  if  the 
bandspread  dial  is  used  as  a  vernier. 

How  badly  a  receiver  needs  such  an  accessory 
depends  on  several  factors.  One  is  the  number  of 
positions  on  the  bandswitch;  in  other  words  how 
much  frequency  is  covered  on  each  tuning  range. 
The  small  inexpensive  receivers  generally  have 
four  bands.  They  require  the  vernier  mechanism. 
Some  have  five  positions,  but  a  fast  tuning  rate. 
They  need  it,  too.  Several  medium-priced  re- 
ceivers have  five  positions  and  a  good  tuning 
rate.  They  benefit  from  the  vernier  drive,  but 
they  can  be  tuned  accurately  without  it.  The 
NC-173  and  183D  are  in  this  category.  A  few 
receivers  have  six  bands.  The  HQ-140-X  and 
SX-88  are  two  we've  tried  that  tune  quite  well 
without  vernier  attachments.  On  Band  4  both 
receivers  cover  just  a  little  more  than  6  to  10 
Mc.  If  the  converter  crystal  frequencies  are 
altered  slightly  from  Handbook  specifications, 
you  have  coverage  of  a  band  with  a  full  sweep  of 
the  general-coverage  dial. 

Any  planetary  drive  can  be  used.  The  National 
Velvet  Vernier  is  one  we've  used  several  times. 
A  moimting  for  the  Type  AM  is  shown  in  the 
second  photograph.  This  gives  the  same  tuning 
rate  as  the  Croname  type  599,  but  the  latter  has 
the  advantage  of  permitting  either  direct  drive  or 
5-to-l  reduction.  The  knob  assembly  supplied  by 
the  manufacturer  can  be  used,  but  we  prefer 
something  larger.  The  lash-up  shown  in  the  first 
photograph  was  made  by  drilling  out  the  center 
of  a  National  HRT  knob  to  pass  the  direct-drive 
portion  of  the  699  shaft.  The  knob  on  the  vernier- 
drive  shaft  is  a  National  type  HRT-M.  Many 
other  combinations  can  be  made  up  to  take  care 
of  individual  tastes  or  available  parts  stocks.

(1)  Advertising  shall  pertain  to  radio  and  shall  be  of 
nature  of  interest  to  radio  amateurs  or  experimenters  in 
their  pursuit  of  the  art. 

(2)  No  display  of  any  character  will  be  accepted,  nor  can 
any  special  typographical  arrangement,  such  as  all  or  part 
capital  letters  be  used  which  would  tend  to  make  one  adver- 
tisement stand  out  from  the  others.  No  Box  Reply  Service 
can  be  maintained  in  these  columns. 

(3)  The  Ham-Ad  rate  is  30^  per  word,  except  as  noted  in 
paragraph  (6)  below. 

(4)  Remittance  In  full  must  accompany  copy.  No 
cash  or  contract  discount  or  agency  commission  will 
be  allowed. 

(5)  Closing  date  for  Ham-Ads  is  the  20th  of  the  second 
month  preceding  publication  date. 

(6)  A  special  rate  of  70  per  word  will  apply  to  adver- 
tising which,  in  our  judgment,  is  obviously  non- 
commercial in  nature,  and  Is  placed  and  signed  by  a 
member  of  the  American  Radio  Relay  League.  Thus, 
advertising  of  bona  fide  surplus  equipment  owned,  used  and 
for  sale  by  an  individual  or  apparatus  offered  for  exchange  or 
advertising  inquiring  for  special  equipment,  if  by  a  member 
of  the  American  Radio  Relay  League  take  the  7«f  rate.  An 
attempt  to  deal  in  apparatus  in  quantity  for  profit,  even 
if  by  an  individual,  is  commercial  and  all  advertising  by 
him  takes  the  30^  rate.  Provisions  of  paragraphs  (1),  (2) 
and  (5),  apply  to  all  advertising  in  this  column  regardless 
of  which  rate  may  apply.  To  expedite  handling  of  your 
copy  please  state  whether  you  are  a  member  of  ARRL. 

(7)  Because  error  is  more  easily  avoided,  it  is  re- 
quested signature  and  address  be  printed  plainly. 
Typewritten  copy  preferred,  but  handwritten  signa- 
ture must  accompany  all  authorized  insertions. 

(8)  No  advertiser  may  use  more  than  100  words  in  any 
one  issue  nor  more  than  one  ad  in  one  issue.

•yHIS  little  quiz  is  base<i  on  articles 
appearing  in   QST  for  February. 
How  much   (do   you   remember  from 
the  issue  of  two  months  ago? 

1.  Signals  may  be  monitored  di- 
rectly, through  use  of  a  monitone,  or 
by  use  of  what  device? 

2.  A  new  approach  to  variable  se- 
lectivity makes  use  of  . 

3.  What  circuit  can  double  in  the 
final  without  loss  of  efficiency? 

4.  Cheap  yet  suitable  chassis  for 
lightweight  accessories  can  be  made 
from  what  common  articles? 

5.  What  method  can  be  used  to  vary 
directivity  of  a  vertical  antenna 
system? 

Some  of  these  questions  can  be  an- 
swered from  a  knowlecige  of  radio 
theory;  others  require  straight  mem- 
ory. Let  a  complete  file  of  QST  serve 
as  your  "memory"  while  it  fills  in 
your  knowledge  of  basic  principles. 
Why  not  have  QST  dehvered  to  your 
door  each  month?

For  instance,  look  at  the  Barker  & 
Williamson  "5 100"  in  this  picture. 

Known  throughout  the  bands 
for  the  authoritative  signal  it 
packs,  this  transmitter  uses  two 
RCA-6l46's  in  parallel  in  the 
"final"— and  two  more  RCA- 
6l46's  in  the  class  AB  modulator. 

Here  are  basic  reasons  why 
leading  amateurs  — and  commer- 
cial designers  like  B&W— specify 
"RCA." 

RCA  power  tubes  make  it 
practicable  to  get  any  power  you 
want— at  relatively  low  plate  volt- 
age. RCA  power  tubes  are  built 
to  handle  peak  plate  loads  with 
ease— have  tremendous  reserve 
emission.  RCA  power  tubes  are 
economical  in  service! 

You  can  get  RCA  high-perve- 
ance  power  tubes— beam  power 
types  and  triodes— from  any  RCA 
Tube  Distributor.  You  can  get 
technical  data  on  any  particular 
type  from  RCA,  Commercial  En-

■""^  AMERICAN 
RADIO  RELAY 
LEAGUE 


INC., 


is  a  noncommercial  association  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
odvancemenf  of  the  rodio  art  and  of  the  public  welfare,  for  the 
representation  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  incorporated  association  without  capital  stock,  chartered 
under  the  lows  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu- 
facture, sale  or  rental  of  radio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amateur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited.  A  bona  fide 
interest  in  amateur  radio  is  the  only  essential  qualification;  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  granted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the,  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us..." 


FIELD  DAY 

One  Saturday  in  mid-June  of  last  yeai', 
from  their  homes  in  Canada,  the  U.  S.  and  pos- 
sessions, eight  thousand  three  hundred  and 
eighty  persons,'  who  otherwise  ai>i;)earefl  per- 
fectly normal,  disappeared  into  woodlands, 
mountains  and  oi:)en  fields  carrying  a  little 
food  and  clothing  and  a  lot  of  radio  apparatus. 
There  they  set  up  two  thousand  and  twenty- 
six^  separate  transmitter-receiver  combina- 
tions operating  independently  of  commercial 
l)()wei'  mains  and  ff)i'  a  solid  twenty-four  hf)urs 
of  the  ARRL  Field  Day  had  themselves  a  time 
etching  the  Kennelly-Heaviside  layer  indelibly 
\\ith"CQFD." 

The  simple  process  of  subtraction  indicates 
that  there  were  114,907  holdei's  of  amateur 
licenses  who  did  not  take  part  in  Field  Day 
fun.  We  think  they  made  a  gieat  mistake  as 
any  participant  in  the  1954  event  will  confirm. 
But  it  is  a  mistake  which  can  easily  be  cor- 
rected —  the  opportunity  will  come  again 
this  June,  on  the  25tli-26th.  And  with  balmy 
days  here  again  for  most  of  us,  now  is  the 
time.  .  .  . 

.  .  .  Time  to  find  out  if  Old  Man  Smith's 
ai)ple  orchard  will  again  l)e  availal)le  for  an 
operating  site.  We've  got  to  try  out  the  gen- 
erator, to  make  sure  the  needle  valve  isn't 
gummed  up  again,  and  that  the  gas  line  isn't 
about  to  expire  from  old  age.  The  tent  will 
have  more  leaks  than  last  year,  but  we'll  try 
the  pai'afiin  again  and  keep  our  fingers  crossed. 
^^'e  take  our  local  public  relations  seriously, 
but  that  new  I'eporter  on  the  Daily  Blast  may 
not  think  a  night  on  a  canvas  cot  contributes 
anything  to  the  j)ublic  knowledge.  Shall  we 
use  an  antenna  changeovei'  I'elay  this  year,  or 
just  toss  a  wire  out  the  window  for  receiving? 
We've  got  to  decide  whether  we'll  have  a  multi- 
station set-up  so  everj^one  can  operate  Sunday 
afternoon,  or  stick  to  one  station  and  keep  it 
busy  all  night.  Bill  Jones'  XYL  will  say  she 
doesn't  think  she  wants  to  provide  the  grub 
this  year,  and  then  change  her  mind,  as 
she  always  does,  and  put  on  a  magnificent 
spread.  .  .  . 

So  we'd  better  devote  the  next  meeting  to 
Field  Day.  And  you'd  better,  too.  First  thing 
you  know  it  will  be  time  to  put  up  the  an- 
tennas,  and  then  you'll  suddenly  remember 

'  And  probably  many  more  not  reported  to  Hq. 


that  one  of  the  masts  got  broken  when  some- 
body let  go  (jf  a  guy  wire  last  year.  And  that 
table  leg  needs  fixing  again.  So,  you  see,  if  you 
don't  get  busy  j^ou're  liable  to  miss  all  the 
fun  —  and  have  only  yourself  to  blame. 

We  think  FD  is  the  top  event  of  the  ama- 
teur yeai-.  Where  else,  in  one  week  end,  can 
you  combine  the  good-fellowship  of  a  hamfest, 
the  underlying  motive  of  preparation  for  public 
service,  the  fresh  air  and  fun  of  a  picnic,  the 
teamwoi'k  of  cooperative  effoi't,  and  the  excite- 
ment of  an  operating  contest?  If  you  haven't 
tried  it  before,  make  it  this  year.  BCNU/1 ! 

MOBILE  SAFETY 

P"oi'  some  time  now  we've  been  on  the  verge 
of  reminding  amateurs  of  the  imjxjrtance  of 
careful  driving  during  mobile  operations,  a 
lesponsibility  accented  by  the  growing  num- 
ber of  states  which  issue  call-letter  license 
plates.  "Lighthouse  Larry"  in  G-E  Ham  News 
last  summer  stated  the  case  so  nicely,  however, 
that  we  can't  do  better  than  commend  to  youi' 
serious  attention  the  following  excerpts  from 
his  eflitorial: 

.  .  .  The  license  plate  program  has  met 
with  considerable  success  throughout  the 
nation  —  and  has  given  us  a  great  boost  in 
publicity.  In  many  cases  we  are  thus  put 
on  a  level  with  doctors  and  other  public 
servants. 

However,  as  we  attain  this  stature  we 
also  have  to  remember  that  it  behooves  us 
to  live  up  to  our  new  standing  —  bj'  added 
care  and  courtesy  on  the  road.  Need  more 
be  said  than  to  comment  that  every  traffic

gets  is  a  l)lack  eye  for  ham  radio?  And 
suppose  through  our  carelessness  it  should 
be  something  worse  than  just  a  "ticket"? 
Suppose  it's  a  broken,  twisted  body  of  a

fervently  hope  I  never  see  one  which  in- 
cludes a  "murder  car"  bearing  ham  call-

You  think  this  is  a  painful  and  unpleasant 
subject?  Sure  is,  but  not  half  as  painful  and 
unjileasant  as  the  real  thing.  We  bring  it  up  in 
the  hopes  that  a  few  thoughts  now,  before- 
hand, may  prevent  the  real  thing  from  ever 
happening.

the  writer  had  decided  to  attempt  to  use  one  in 
reverse,  and  some  interesting  results  were  ob- 
tained. 

The  "Z-match"  antenna  coupler  is  designed 
for  use  with  transmitters  having  up  to  250  watts 
input,  and  will  match  a  50-ohm  coaxial  line  to

the  standpoint  of  convenience  and  ease

10  to  2500  ohms.  It  covers  the  frequency  range 
of  3.5  to  30  Mc.  without  switching  coils.  One  of 
the  most  important  features  of  the  unit  is  the 
fact  that  all  matching  is  done  visuall\-,  with  a 
Micromatch  t>pe  s.w.r.  bridge. 

Additional  features  incorporated  in  the  "'Z- 
match''  besides  the  all-band  tank  circuit  are  a 
50-ohm  dummy  load  and  a  power-indicating  de- 
vice that  is  left  in  the  line  at  all  times,  reading 
either  forward  or  reflected  power  as  selected  by 
a  front-panel  switch.  Two  output  links  are  pro- 
vided, for  either  low-frequency  (3.5  to  7.3  Mc.) 
output  or  high-frequency  (14  to  30  Mc.)  output. 
.\  second  front-panel  control  is  provided  for  the 
selection  of  various  functions.  The  noninductive 
50-ohm  dummy  load  is  connected  in  circuit  in 
Position  1,  while  the  second  position  switches  the 
transmitter  to  the  coupler  proper.  Position  3 
switches  the  transmitter  to  a  50-ohm  output  con- 
nection which  is  independent  of  the  coupler  but 
allows  the  u.'«e  of  the  power-measuring  device 
when  feeding  directly  into  a  matched  50-ohm  line. 

The  complete  schematic  is  shown  in  Fig.  1. 
Like  most  homebuilt  projects,  other  parts  can  be 
substituted.   However,  care  should  be  taken  in 


The  muitihand  tank  circuit 
consists  of  the  split-stator  ca- 
pacitor at  the  left  and  the  two 
inductors,  with  links,  in  the 
center.  Coupling  is  controlled 
by  the  tank  and  the  capacitor 
at  the  right.  The  two-terminal 
assemblies  connect  to  the  two 
link  coils.

following  the  layout  of  the  unit,  especially  the 
forward-  and  retteeted-power  indicating  device. 

Construction 

The  "Z-match"  shown  in  the  photographs  is 
built  on  an  11%  X  d\i  X  2i2-inch  chassis,  and 
the  panel  is  12ii  by  6%  inches.  These  were  used 
beeaus?  they  were  on  hand,  but  any  number  of 
commercially-available  chassis  and  dust-cover 
comlMnations  could  be  used  with  good  results. 

The  chassis  itself  is  used  to  separate  the  low- 
impedance  input  circuits  from  the  comparatively 
high-Z  output  circuits,  and  no  matter  what  size 
chassis  is  used  this  constructional  practice  should 
be  followed.  The  coupling  capacitor  C'lo  is  elec- 
trically above  ground  and  is  mounted  on  two 
feed-through  insulators  (Johnson  type  135-55), 
one  of  which  is  used  to  bring  the  electrical  con- 
nection through  the  chassis  to  the  rotor  of  Ciq. 
This  capacitor  is  set  back  from  the  panel  and 
coupled  to  the  dial  by  an  insulated  shaft,  thus 
eliminating  body  capacity.  Cn  is  mounted  at 
the  other  end  of  the  chassis  and  the  control  is 
brought  out  through  the  panel  with  symmetry 
in  mind.  Inductors  L2  and  L4  are  mounted  near 
the  rear  output  terminal  panel,  mainly  because 
this  is  the  high-frequency  section  (14  to  30  Mc.) 
and  over-all  lead  length  should  be  kept  to  a 
minimum.  Coils  Li  and  L3  are  mounted  at  right 


angles  to  Lo  and  L4  to  reduce  mutual  coupling. 

The  output  terminal  panel  on  the  rear  of  the 
chassis  has  two  National  type  FWH  connectors 
and  a  wing-nutted  ground  terminal,  allowing  the 
operator  to  connect  either  balanced  or  unbalanced 
antennas.  The  two  output  terminals  (high  and 
low  frequency)  could  very  well  be  one,  if  an 
antenna  changeover  relay  was  used,  although 
separate  connectors  are  convenient  when  separate 
antennas  are  used. 

The  two  rotary  switches  *Si  and  So  are  placed 
in  a  position  to  maintain  panel  symmetry,  and 
also  to  keep  lead  lengths  to  a  minimum  for  the 
connections  to  So.  As  can  be  seen  from  the  photo- 
graphs, the  50-ohm  dummy  load  is  mounted  on 
standard  fuse  clips  and  the  "hot"  end  is  kept  as 
close  to  the  ceramic  switch  S2  as  possible.  The 
dummy  load  has  been  insulated  from  the  chassis 
at  the  hot  end  by  a  }^-inch-thick  phenolic  block; 
however,  the  same  feed-through  that  was  used 
on  Cio  could  be  used  instead.  The  grounded  end 
is  raised  up  from  the  chassis  merely  in  keeping 
with  good  constructional  practice.  This  can  be 
done  with  a  metal  spacer  having  the  same  height 
as  either  the  phenolic  block  or  the  feed-through 
type  insulator,  whichever  is  used. 

The  rear-view  photograph  shows  the  output 
terminals  marked  as  "parallel"  and  "series." 
These,  however,  could  be  called  "low-frequency"

S.W.R.  Bridge 

The  s.w.r.  bridge  consists  of  two  bridges  con- 
nected back  to  back  so  that  incident  and  re- 
flected power  may  be  determined.  The  theor\- 
and  operation  have  been  abl>-  presented  elsewhere 
and  will  not  be  dealt  with  here.^ 

The  incident-power  bridge  consists  of  R\,  To, 
('(,  and  the  transmitter  output  impedance:  the 
reflect ed-power  bridge  consists  of  Ri,  C'l,  C-i  and 
the  load.  The  output  of  the  bridge  is  rectified  by

the  crystal  diodes.  A  d.c.  path  is  provided  b}-  the 
r.f.  choke.  The  rest  of  the  components  are  used 
for  r.f.  filtering. 

/?i  consists  of  sixteen  10-ohm  3^-watt  composi- 
tion resistors  in  parallel.  Since  the  bridge  is  de- 
signed to  operate  from  3  to  30  Mc,  it  is  impor- 
tant that  noninductive  resistors  be  used.  For  best 
results,  (\  and  C\  should  be  of  the  button  type. 
They  proved  to  be  decidedly  better  than  silver 
micas.  Needless  to  say,  all  lead  lengths  should 
be  kept  as  short  as  possible  to  reduce  the  effects 
of  lead  inductance.  The  layout  shov\-n  in  the 
photograph  should  be  followed,  and  since  this 
shows  the  placement  of  parts  quite  clearly,  con- 
structional details  will  be  omitted. 

In  the  initial  set-up  of  the  bridge,  set  So  to  the 
dummy  load  position,  apply  r.f.  power  to  the 
input  terminal,  and  adjust  ('2  for  zero  deflection. 
Next,  temporarily  reverse  the  bridge  and  adjust 
C'e  for  zero  deflection.  Then  return  to  the  original 
input-output  connections  and  the  bridge  is  ready 
for  calibration.  A  good  calibration  will  require 
comparison  with  an  already-calibrated  power 
meter,  or  by  calculation  from  the  r.f.  current  in 
the  dummy  load  as  measured  by  an  r.f.  ammeter 
connected  in  series  with  the  load.  The  full-scale 
power  values  (three  ranges  are  provided  for)  may 
be  set  by  adjusting  R2,  R3  and  7^4.  However,  an 
actual  power  calil)ration  is  not  at  all  necessary 
to  the  operation  of  the  "Z-match,"  since  the 
bridge  will  serve  quite  well  both  for  adjustment 
of  coupling  and  for  relative  power  indications 
without  calibration. 

The  meter  used  in  the  bridge  has  a  basic  move- 
ment of  0-200  microamperes,  and  in  this  case  a 
hand-calibrated  scale  was  made  by  taking  the 
original  meter  plate  off  and  reversing  it.  The 
three  scales  were  then  hand-painted  on,  as  the 
l)hotograph  shows. 

Operation 
The  bridge  provides  a  visual  way  of  adjusting 
the  coupler,  while  the  50-ohm  noninductive  load

power  calibration  of  the  bridge

Automatic  Mobile  Antenna  Tuning 

A  Self- Resonating  System  for  40  and  75 

BY  JOHN  A.  HARGRAVE,*  W0IGP 


IT  is  obvious  that  mobile  operation  of  the  ama- 
teur station  has  increased  many  times  during 
the  past  several  years.  While  the  10-,  15- 
and  20-meter  bands  offer  a  general  efficiency 
and  convenience  of  operation  from  a  mobile  sta- 
tion comparable  to  that  of  the  home  station, 
40  and  75  meters  present  a  more  difficult  prob- 
lem. This  may  be  attributed  primarily  both  to 
practical  power  limitations  and  poor  radiation- 
system  efficiencies.  It  has  been  generally  proven 
that,  e.xcept  for  increased  physical  length,  the 
greatest  single  factor  contributing  to  the  effi- 
ciency of  a  loaded  antenna  system  is  loading- 
inductor  efficiency  or  Q.  The  greater  the  r.f. 
resistance  of  a  given  loading  inductance,  the 
greater  will  be  the  r.f.  loss  resulting  from  its 
operation.  It  becomes  apparent  that  for  a  practi- 
cal figure  o'  efficiency,  maximum  practical  load- 
ing-inductor Q  must  be  maintained,  and  general 
transmitter  and  coupling  efficiency  must  be  kept 
at  a  reasonably  high  figure. 

The  expression  "high  Q"  is  a  relative  quantity 
and  strictly  dependent  on  the  peculiar  interpre- 
tation of  the  user.  High  Q  is  generally  synono- 
mous  with  the  presence  of  a  sharply  resonant 
circuit  with  a  narrow  bandpass  characteristic. 
Generally  speaking,  a  high-Q  5-  to  8-foot  mobile 
whip  antenna,  loaded  for  the  75-meter  band, 
will  be  sharply  resonant,  and  will  begin  to  appear 
seriously  reactive  at  a  deviation  from  the  carrier 
frequency  of  about  5  kc.  Any  effort  to  broaden  the 
response  by  loading-inductor  construction  will, 
in  the  majority  of  cases,  be  merely  a  compromise

those  working  40  and  75,  understand  the

Mobile  VFO  seems  like  a  marvelous  convenience 
until  it  is  realized  that  the  carefully  designed  an- 
tenna system  is  restricted  to  a  bandwidth  of  a 
few  kilocycles.  It  is  mechanically  practical  to 
provide  an  adjustable  whip  length  or  to  afford  a 
manually  adjustable  inductor  to  enable  multi- 
frequency  operation,  although  their  location  by 
necessity  must  be  remote  from  that  of  the  under-

QST  for 


Within  this  article  is  described  a  system  for 
use  over  the  40-  and  75-meter  bands  providing 
automatic  adjustment  of  antenna  resonance  in 
response  to  the  output  frequency  of  the  mobile 
transmitter.  It  permits  maximum  use  of  VFO 
control  and  convenient  use  of  maximum-Q  an- 
tenna systems.  This  system  was  installed  in  the 
author's  1953  Buick  and  has  proven  very  success- 
ful and  a  great  convenience.  The  present  mobile 
transmitter  runs  40  watts  input,  but  the  S3^stem 
has  been  used  successfully  with  input  powers  of 
from  15  to  300  watts.  Although  the  system  was 
designed  for  mobile  operation,  it  has  been  used 
experimentally  on  a  fixed-station  vertical  and  has 
proven  very  satisfactory. 

Circuits  and  Theory 

This  system '  consists  of  a  device  for  detecting 
antenna  resonance,  and  provides  control  of  a 
reversible  motor  which  is  coupled  to  a  variable 
antenna-tuning  inductance  located  at  the  base  of 
the  antenna.  An  inductive  load,  as  observed  by 
the  detector,  will  cause  the  motor  to  rotate  in 
one  direction,  while  a  capacitive  load  will  cause  it 
to  operate  in  the  other  direction,  such  rotation 
reestablishing  antenna  resonance. 

It  is  generally  understood  that  an  r.f.  trans- 
mission line  terminated  in  a  pure  resistance 
equal  to  its  characteristic  impedance  will  be  flat. 
This  means  that  there  will  be  no  reflections  from 
the  loaded  end  of  the  line,  and  that  at  any  point 
along  that  line  the  voltage  and  current  will  be 
in  phase.  A  high-(?  antenna  may  Ix;  matched  to 
a  given  type  of  transmis.sion  line  but,  should  the 
resonant  frecjuency  of  the  load  shift  to  a  slightly 
higher  or  lower  frequency,  or  should  the  exciting 
frequency  change  to  a  lower  or  higher  frequency, 
the  antenna  system  will  no  longer  present  a 
purely  resistive  load  to  the  transmission  line  and 
a  complex  load  will  reflect  a  standing  wave  back 
along  the  transmission  line.  Under  such  a  condi- 
tion a  shift  in  voltage/current  phase  and  ampli- 
tude relationship  will  result.  These  factors  pro- 
duce an  increase  in  load  impedance  and  a  sig- 
nificant drop  in  transmitter  loading.  The  detect- 
ing system  operates  as  a  result  of  these  variables 
reestablishing  a  resistive  termination. 

The  phase  detector  used  in  this  system  is  quite 
similar  to  the  Foster-Seeley  f.m.  discriminator. 
Operation  of  the  conventional  discriminator  re- 
sults from  the  phase  relationships  existing  in  a 
transformer  having  a  tuned  primary  and  second- 
ary, both  capacitively  and  inductively  coupled. 
The  phase  detector  shown  here  in  Fig.  1  operates 
from  a  low-Q  impedance,  both  capacitively  and 
inductively  coupled  to  the  r.f.  antenna  transmis- 
sion line.  This  impedance,  represented  by  L2  and 
its  distributed  circuit  capacitances,  provides 
sufficient  impedance  for  satisfactory  circuit  opera- 
tion and  avoids  the  inconvenience  of  a  tuned  tank. 
As  was  previously  stated,  providing  a  proper 
match  exists  between  the  r.f.  load  and  its  trans-

mission  line,  r.f.  current  and  voltage  on  such  a 
line  will  be  in  phase.  The  voltage  on  the  line  is 
used  as  a  reference,  and  a  small  amount  of  this 
voltage  is  coupled  into  the  detector  circuit 
through  the  distributed  capacitance  existing  be- 
tween L\  and  L2.  The  relative  amount  of  this

voltage  applied  to  the  detector  circuit  is  deter- 
mined by  the  capacitive  voltage-divider  ratio  of 
the  distributed  capacitance  between  Li  and  L2, 
Cx,  and  the  value  of  capacitor  Ci.  A  second 
voltage,  necessary  to  provide  a  medium  of  phase 
comparison,  is  introduced  as  a  result  of  line  cur- 
rent flowing  through  Li.  Such  a  current  will 
create  a  magnetic  field  about  Li  and,  because  of 
mutual  inductance,  will  produce  a  current  and 
resultant  voltage  in  the  secondary  coil  L2.  The 
resulting  voltage  across  L2  will  lag  the  inducing 
current  through  Li  by  90  degrees. 

The  two  voltages  described  above  appear  in 
series  between  the  plate  of  each  diode  and  the

In  the  event  of  antenna  detuning  or  a  change 
in  transmitter  frequency,  a  change  in  the  current 
and  voltage  phase  relationship  along  the  trans- 
mission line  will  result,  and  a  balanced  output 
from  FiA  and  Fib  will  no  longer  exist.  It  may 
again  be  said  that  the  reference  voltage  intro- 
duced by  the  capacitive  coupling  is  in  phase 
with  the  voltage  along  the  line,  but  there  is  no 
longer  a  90-degree  phase  relationship  between 
this  voltage  and  that  developed  across  L2  as  a 
result  of  line  current  through  Li  and  Li-Lo 
mutual  inductance.  Under  such  conditions,  phase 
relationships  similar  to  the  vectors  indicated  in 
Figs.  2B  and  2C  will  result.  From  this  it  ma}'  be 
seen  that  a  phase  shift  in  one  direction,  as  a 
result  of  a  change  in  the  exciting  frequency,  or  a 
change  in  the  frequency  of  antenna  resonance, 
will  cause  the  detector  to  produce  a  negative  out- 
put voltage,  while  the  opposite  change  in  fre- 
quency or  antenna  resonance  will  cause  the  de- 
tector to  produce  a  positive  output  voltage.  Po- 
tentiometer Ri  is  a  balancing  control,  the  proper 
adjustment  of  which  will  overcome  circuit  un- 
balances and  will  provide  l)alanced  output. 

The  comi)lete  control  circuit  is  shown  in  Fig.  8. 
The  GALS  phase  detector  provides  a  d.c.  out- 
put voltage  of  either  positive  or  negative  polarity 
dependent  upon  the  resonant  fre(ju(!ncy  of  the 
antenna  system  in  reference  to  the  transmitter 
operating  frecjuency.  This  output  voltage  is  ap- 
plied to  the  grid  of  a  d.c.  amplifier,  F2A,  Fig.  3. 
ViA  is  cathode-coupled,  by  way  of  cathode  re- 
sistor Ri,  to  F2B,  and  the  plate  circuits  of  both 
sections  of  F2  are  directly  coupled  to  the  grids  of 


the  control  tube,  F3.  In  order  to  provide  d.c. 
voltage  amplification,  direct  interstage  coupling 
is  necessar3^  This  arrangement  places  the  entire 
plate  potential  of  F2A  and  F2B  on  the  respective 
control  grids  of  F3.  Under  conditions  of  antenna 
resonance,  the  phase  detector  provides  approxi- 
mately zero  volts  output,  and  sensitivity  control 
i?3  is  adjusted  to  the  point  where  the  static  plate 
current  of  F3A  and  Fsb  will  not  hold  relays  K\ 
and  Ko  in  the  energized  position.  This  adjustment 
places  the  cathodes  of  F3  at  a  more  positive  po- 
tential than  their  respective  control  grids,  this 
bias  being  of  such  magnitude  as  to  approach 
plate-current  cut-off. 

Following  adjustments  of  balance  and  sensi- 
tivity, any  slight  change  in  phase  detector  out- 
put will  cause  either  A'l  or  K2  to  operate,  causing 
the  tuning  motor  to  rotate  in  one  direction  or  the 
other. 

Matching  Antenna  to  Line 

It  is  necessary  that  tlie  transmission  line  from 
the  transmitter  to  the  loaded  antenna  be  made 
relatively  flat  if  smooth  indication  and  operation 
is  desired  from  one  band  edge  to  the  other.  This 
may  sound  like  a  difficult  task,  but  the  adjust- 
ment may  be  made  with  very  little  eciuipment 
or  effort.  It  essentially  requires  that  the  loaded 
antenna  at  resonance  present  the  same  load  to 
the  transmission  line  as  a  noninductive  resistor 
equal  in  resistance  to  the  characteristic  imped- 
ance of  the  transmission  line.  Providing  no  more 
than  20  watts  of  power  is  made  available  at  the 
base  of  the  loaded   whij),   ten  500-ohm  2-watt

carbon  resistors  may  be  placed  in  parallel  to  act 
as  a  dummy  load  for  RG-8/U  cable.  The  imped- 
ance-matching system  utilized  with  this  antenna 
consists  of  a  plug-in  coil,  Lo,  Fig.  4,  mounted 
on  the  remote  tuning  unit,  and  connected  from 
the  input  side  of  the  variable  loading  inductoi', 
Li,  to  the  automoi)ile  body.  A  satisfactory  ad- 
justment may  be  made  by  establishing  normal 
transmitter  loading  with  the  dummy  load,  then 
switching  to  the  antenna  s\stem  and,  while 
maintaining  antenna  resonance,  adjusting  the 
matching  inductance  for  identical  load  condi- 
tions. It  will  be  found  that  a  difference  of  as 
much  as  one  quarter  turn  will  have  considerable 
effect  on  loading  and  the  proper  impedance 
match.  A  6-turn  coil  1  Yi  inches  in  diameter,  2 
inches  long,  was  found  satisfactory  for  this  par- 
ticular installation  when  operating  in  the  75- 
meter  band.  The  circuit  for  the  remote  tuning 
unit  is  shown  in  Fig.  4  and  a  photograph  of  the 
unit  is  also  included. 

General  Design 

This  system  contains  two  i)asic  units: 

1)  The  control  unit  consisting  of  a  4  X  4  X 
2-inch  bo.\  mounted  beneath  the  instrument 
dash,  and  containing  all  detecting  and  control 
circuits  and  components  other  than  the  motor, 
the  motor-reversing  relay  and  the  impedance- 
matching  and  variable  inductors.  All  components 
associated  with  the  control  unit  are  mounted 
within  the  box  with  the  exception  of  the  three 
vacuum  tubes.  These  are  mounted  on  the  rear 
lip  of  the  unit  to  afford  ade(}Uate  circulation  of 
air. 

2)  The  remote  tuning  unit  is  located  in  the 
automol)ile  trunk,  adjacent  to  the  base  of  the 
loaded  wliij).  It  contains  the  variable  .series  in-

indicated  bj-  l)oth  lamps  being  extinguished. 
The  three-pole  four-position  switch  utilizes 
the  four  positions  as  follows:  (1)  off,  (2)  auto- 
matic tuning,  (3)  manual  increase  inductance, 
and  (4)  manual  decrease  inductance.  During 
normal  operation,  the  switch  will  be  left  in 
Position  2  except  on  10,  15,  and  20  meters,  where 
the  antenna  bandwidth  is  sufficiently  broad  that 
automatic  tuning  is  not  necessary.  In  this  case, 
the  switch  may  be  left  in  the  off  position.  When 
QSYing  from  one  end  of  a  band  to  the  other,  it 
is  not  necessary  to  keep  the  transmitter  on  the 
air  while  waiting  for  the  antenna  to  be  tuned  to 
resonance.  While  on  automatic  position  the  VFO 
may  be  adjusted  to  the  desired  frequency,  the 
transmitter  output  tank  adjusted  to  resonance 
and  note  made  whether  the  antenna  is  inductive 
or  capacitive  as  indicated  by  the  two  pilot  lights. 
The  transmitter  maj^  then  be  taken  off  the  air 
and  the  control  switch  placed  in  one  of  the  two 
manual  positions  for  an  approximate  adjustment 
of  the  series  inductance.  The  switch  may  then 
be  returned  to  the  automatic  position  for  an 
exact  antenna  adjustment. 

Construction 

Inductor  L2,  Fig.  3,  consists  of  20  turns  of 
No.  18  enameled  wire  close-wound  and  center- 
tapped  on  a  ^-inch  bakelite  rod.  Li  is  formed 
of  No.  16  wire  and  consists  of  a  M-turn  loop 
about  Lo.  This  provides  an  optimum  value  of 
coupling  for  25-50-watt  transmitters.  Although 
the  coupling  between  Li  and  L2  is  not  critical, 
it  should  be  reduced  as  higher  transmitter  power 
is  employed.  A  slight  change  of  coupling  may  be 
found  necessary  with  different  installations. 

To  facilitate  construction  procedures,  the  con- 
trol unit  was  assembled  and  wired  with  l)oth 
4  X  4-inch  covers  removed.  This  simplifies  the 
task  of  assembling  and  wiring  considerably.  As  an 
aid  to  simplification  it  is  recommended  that  wires 
be  cabled  together  where  practical,  even  though 
it  may  require  greater  lead  length.   Where  no 


critical  circuits  are  involved,  cabling  will  greatly 
limit  the  congestion  which  is  unavoidable  with 
a  unit  of  this  size.  Of  course,  the  leads  to  Li  and 
Lo  should  be  kept  short  and  direct. 

The  tuning  motor  was  originally  an  auto- 
mobile defroster  motor  purchased  at  a  used 
auto-supply  store  for  $1.00.  It  was  disassembled 
and  leads  brought  out  for  connection  to  the 
d.p.d.t.  reversing  relay.  Six-  and  12-volt  d.c.  mo- 
tors may  be  wired  in  a  number  of  ways.  Fre- 
quently, the  armature  is  connected  between  the 
two  fields,  and  the  combination  placed  in  series 
across  the  automobile  battery.  In  this  case  the 
most  simple  way  to  provide  a  reversal  of  rotation 
is  by  reversing  the  armature  connections  in 
respect  to  the  field  windings.  In  other  cases  a 
field  reversal  may  be  more  simply  accomplished. 

The  gear  reduction  unit  was  taken  from  a 
PE-101  dynamo  tor  where  it  was  originally  used 
to  operate  an  automatic  keyer.  The  variable  in- 
ductor, Li,  Fig.  4,  was  taken  from  a  military 
Command  transmitter.  All  other  components  are 
of  standard  manufacture  and  readily  available 
at  most  radio  supply  houses.  A  simple  replace- 
ment for  the  entire  antenna  tuning  unit  would 
be  a  motor-driven  variable  inductor  which  is 
available  commercially. 

Power  for  the  automatic  mobile  tuner  is  taken 
directly  from  the  mobile  transmitter.  The  fila- 
ments are  not  switched  on  or  off  within  the  unit 
itself,  but  are  taken  directly  from  the  transmitter 
filament  switch.  The  unit  requires  0.9  amp.  at 
6  volts  and  200-400  volts  at  approximately  15 
ma.  Satisfactory  sensitivity  may  be  realized  with 
voltages  as  low  as  200,  although  an  increase  in 
L1-L2  coupling  may  be  found  necessary.  Voltages 
over  400  should  be  avoided  because  of  possible 
cathode-to-heater  break-down  in  V3.

Provided  the  antenna  system  has  been  prop- 
erly matched  to  the  transmission  line  in  use,  the

multiband  antennas  because  their  angle  of  radia- 
tion increases  with  frequency.  This  is  true  except 
for  the  region  where  the  vertical  antenna  is  less

0.64  wavelength  long  the  radiation  angle  de-

different  frequencies.  These  curves  assume  zero

resistive  loss  in  the  antenna  will  merely  shrink

The  main  object  ion  to  an  antenna  which  is 
operated  at  different  points  in  this  0.64-  to  0.20- 
wavelength  region  is  the  radical  change  in  input 
impedances  between  the  bands  where  the  antenna 
is  current  fed  and  the  band  where  the  antenna 
is  voltage  fed.  By  using  a  simple  construction 
technique  the  amateur  can  approximate  a  cylin- 
drical antenna  of  low  enough  length-to-diameter 
ratio  to  reduce  materially  these  variations  in 
impedance.  Figs.  2  and  3  show  the  manner  in 
which  input  resistance  and  reactance  of  a  vertical 
cylindrical  antenna  vary  with  frequency  in  the 
region  where  the  antenna  is  less  than  0.65 
wavelength  long,  and  for  antenna  length-to- 
diameter  ratios  of  60:1,  100:1,  and  5620:1.  A 
length-to-diameter  ratio  of  5620:1  is  equivalent 
to  30  feet  of  No.  14  wire. 

Practical  Antennas 

If  the  vertical  antenna  can  be  erected  close 
enough  to  the  rig  to  minimize  transmission-line 
losses,  the  two  antennas  described  here  can  be 
made  to  operate  very  satisfactorily.  Fig.  4  shows 


a  29.0-foot  antenna  with  a  60:1  effective  length- 
to-diameter  ratio  that  operates  very  well  on  40, 
20,  and  15  meters.  The  current  distribution 
along  the  antenna  at  the  center  of  each  band 
is  represented  by  the  dotted  lines.  The  values 
of  input  impedance,  optional  series  inductance 
which  may  be  used  to  cancel  out  the  capacitive 
component  of  the  input  impedance,  and  the 
voltage  standing- wave  ratio  with  and  without 
the  series  inductance,  are  all  given  for  the 
center  of  each  band.  The  v.s.w.r.  values  are 
for  the  case  where  the  antenna  is  fed  with  52-ohm 
coaxial  cable.  With  this  antenna  the  series 
inductance  makes  very  little  difference  in  cable 
loss;  for  example,  at  7.15  Mc.  the  loss  in  100 
feet  of  RG-8/U  cable  without  the  inductance 
would  be  0.62  db.  and  with  the  inductance  it 
would  be  0.55  db.  At  21.225  Mc.  the  loss  without 
the  inductance  is  1.9  db.  and  with  the  inductance 
it  is  0.83  db.  If  this  antenna  is  to  be  used  ex- 
tensively on  20  meters,  the  length  of  the  feed 
line  is  of  special  importance.  With  the  9-to-l 
v.s.w.r.  which  exists  on  20  meters,  the  loss  in 
100  feet  of  cable  will  be  2.3  db.  This  will  have 
the  same  effect  as  reducing  a  100-watt  rig  to  about 
60  watts.  With  50  feet  of  cable  the  loss  will  be

A  vertical  antenna  for  the  2()-,  15-,  11-,  and 
10-meter  band?  i.s  shown  in  Fig.  5.  This  antenna 
is  22.16  feet  long  with  a  100:1  effective  length-to- 
diameter  ratio.  The  series  condenser  for  use  on 
20  meters  is  relatively  unimportant  and  may 
be  omitted  as  it  only  reduces  the  loss  in  100 
feet  of  RG-8/U  from  1.2  db.  to  0.75  db.:  how- 
ever, on  11  and  10  meters  the  series  inductance 
should  be  used  unless  a  very  short  run  of  cable  is 
used  between  the  rig  and  the  antenna.  The  loss 
on  11  and  10  meters  is  3.7  and  3.6  db.,  respec- 
tively, for  100  feet  of  cable  without  inductance, 
and  that  loss  is  reduced  to  1.2  and  1.0  db.,  respec- 
tively, when  the  series  inductance  is  used. 

Construction  Notes 

The  construction  of  the  antenna  is  fairly 
simple,  as  shown  in  Fig.  6.  The  l)ox  construction 
with  length  D  on  a  side  approximates  a  cylindrical 
antenna  of  diameter  D.  The  diameter  of  the 
four  vertical  wires  is  not  critical,  but  should  be

as  large  as  possible  to  reduce  resistive  loss.  No. 
14  wire  is  satisfactory  and  was  used  bj^  the 
author,  but  a  larger  size  would  probably  be  an 
improvement.  Either  solid  or  stranded  may  be 
used. 

The  separators  are  not  critical  and  may  be 
plastic  or  treated  wood.  The  spacing  of  the 
separators  is  dependent  upon  the  tension  used 
on  the  antenna:  the  more  tension  used  the  fewer 
separators  needed.  The  author  used  ten  separa- 
tors for  each  antenna.  The  spring  used  at  the 
top  to  provide  the  tension  was  an  over-sized 
screen  door  spring  obtained  at  the  local  hardware 
store. 

The  series  inductances  can  be  wound  on  any 
convenient  low-loss  form,  and  the  size  of  wire, 
number  of  turns,  spacing,  and  coil  diameter 
may  be  picked  to  fit   the  specific  installation. 

*  The  Radio  Amalevrs  Handbook,  page  545,  30th  edition; 
page  543,  31st  edition. 


The  ARRL  Lightning  Calculator  or  any  available 
coil  table  such  as  the  one  in  The  Radio  Amateitr's 
Handbook^  may  be  used  to  wind  the  inductance 
required.  The  author  found  that  Xo.  12  wire 
on  a  1 2-inch  synthane  tube  \\\\\  work  satis- 
factorily. The  coils,  if  used,  must  be  placed  in  a 
waterproof  box  and  a  stepping  relay  used  to 
select  the  correct  coil  for  each  band,  or  to  short 
out  the  coil(s)  where  none  are  required.  The 
author  strongly  suggests  keeping  the  coaxial 
cable  short,  connecting  it  directly  to  the  antenna 
and  not  using  any  series  reactance. 

The  use  of  ground  radials  is  important,  as 
with  any  vertical  antenna.  It  is  recommended 
that  4  or  more  buried  radials  be  used  and  that 
they  be  more  than  ^4  wavelength  long  at  the 
lowest  frequency-  to  be  used.  The  author  has 
found  that  four  50-foot  sections  of  aluminum 
clothesline  running  at  right  angles  from  the 
base  of  the  antenna  work  very  satisfactorily. 
One  of  these  radials  runs  in  one  window  of  the 
basement  of  the  house,  along  the  basement 
ceiling  and  out  the  opposite  window.  In  addition 
to  the  radials,  a  long  (6  feet  or  longer)  ground 
rod  should  lie  driven  into  the  ground  at  the  base 
of  the  antenna  and  connected  to  the  junction  of 
the  radials  and  the  outer  conductor  of  the  coax. 

The  antenna  may  be  held  up  by  any  suitable 
means,  but  the  most  convenient,  in  most  cases, 
will  probably  be  a  clothesline  running  between 
two  suitable  supports  such  as  two  trees,  a  tree 
and  the  house,  etc. 

It  must  be  remembered  that,  as  shown  in  Fig. 
1,  the  vertical  antenna  has  a  low  radiation  angle; 
therefore,  don't  expect  it  to  perform  well  at 
short  ranges  where  a  high  angle  of  radiation  is 
needed.  The  author  has  a  horizontal  dipole  35 
feet  above  the  ground  for  use  on  40  meters.  This 
antenna  outperforms  the  40-20-15  vertical  when 
working  nearby  stations  (30  to  200  miles)  but 
when  the  band  is  open  tlie  vertical  puts  the 
dipole  to  shame.

Six  Meters  for  the  Beginner 

Part  I—  The  Nature  of  the  Band 

BY  EDWARD  P.  TILTON,  WIHDQ 


EXPERIENCE  on  the  2-meter  hand  since  Novices 
appeared  on  the  scene  has  shown  us  what 
makes  the  wheels  go  around  in  amateur 
radio.  Today  we  find  Novices  and  former  Novices 
almost  everywhere,  enjoying  what  the  band  has 
to  offer.  Hundreds  started  on  2  as  WNs  or  KNs 
and,  liking  what  they  found,  have  stayed  there 
after  graduating  to  General  Class  status.  This 
has  been  fine  for  2-meter  activity,  but  in  at- 
tracting the  lion's  share  of  all  v.h.f.-minded 
beginners,  the  2-meter  band  has  left  its  next- 
lower  neighbor,  the  50-Mc.  band,  with  very 
little  new  blood. 

The  drive  of  the  newcomer  is  vital  to  the 
growth  of  our  hobby.  Wherever  he  congregates, 
things  happen;   there   is   no   substitute   for  his 


BE<ilMMEt2S 
MAKE  TME  WHEELS 


boundless  enthusiasm.  It  was  with  this  thought 
in  mind  that  the  ARRL  Board  of  Directors 
endorsed  the  proposal  to  open  the  50-Mc.  band 
to  Technician  licensees.  Let's  look  over  the 
characteristics  of  this  recently  somewhat-neg- 
lected band,  and  see  what  it  has  to  offer  the 
fellow  who  is  just  breaking  into  the  game,  at 
either  the  Technician  or  General  Class  level. 

Why  Start  on  6? 

In  v.h.f.  circles,  activity  begets  activity.  Noth- 
ing discourages  a  potential  v.h.f.  operator  more 
than  to  listen  in  and  hear  no  signals.  "There's 
nobody  here,"  he  concludes,  "why  should  I  go 
on?"  But  if  he  tunes  across  the  Ijand  and  hears 
people  talking  together  he  concludes  that  some- 
thing interesting  is  going  on,  and  he  feels  the 
urge  to  join  in. 

What  the  casual  tuner-inner  may  misunder- 
stand about  the  50-Mc.  band,  if  he  finds  it  un- 
occupied at  the  moment,  is  that  it  is  not  always 
quiet.  There  are  6-meter  men  scattered  all  across 
the  country  who  wouldn't  give  up  the  band  for 
anything  else  in  ham  radio.  They  watch  the 
band  constantly.  Perhaps  you  don't  hear  them 
for  weeks  at  a  time,  but  they're  around.  Just 
let  a  sign  of  DX  show  up  and  they'll  be  in 
there  soon  enough.  Others  crawl  out  from  under 


their  rocks  for  every  v.h.f.  contest,  and  disappear 
promptly  again  when  the  party  is  over. 

These  are  the  old-time  v.h.f.  men,  mostly. 
They  have  a  wonderful  time  on  6,  but  their 
kind  of  operating  is  by  no  means  enough  to  make 
things  interesting  for  the  beginner,  or  even  the 
casual  old-timer.  Most  hams  want  merely  to  talk 
with  someone  —  and  6  is  fine  for  that  too,  or  it 
could  be  if  more  stations  used  it  for  that  purpose. 
In  fact,  there  is  probably  no  better  band  in  all 
the  spectrum  for  friendly  rag-chewing  over  dis- 
tances up  to  5'J  miles  or  more.  It  may  not  provide 
the  strongest  signals,  or  the  best  DX,  but  it 
certainly  does  afford  the  most  consistent  com- 
munication, within  its  reliable  range,  of  any 
band  we  have. 

The  50-Mc.  band  is  in-between  territory.  It 
has  the  reliable  coverage  of  higher  v.h.f.  bands 
and,  like  them,  it  is  almost  entirely  free  of 
serious  interference  problems.  Yet  it  is  low 
enough  in  frequency  so  that  the  ionosphere  gets 
into  the  act  now  and  then,  opening  the  band 
up  for  DX  that  may  be  international  or  even 
world-wide  in  scope.  Essentially,  though,  it  is 
a  local  or  extended-local  band,  for  the  DX  is 
available  only  a  small  percentage  of  the  total 
time  each  year.  DX  on  6,  then,  should  be  re- 
garded as  a  spice,  added  occasionally  to  a  satisfy- 
ing daily  fare,  and  not  as  an  end  in  itself. 

Even  if  we  ignore  DX  entirely,  the  50-Mc. 
band  has  much  to  interest  the  beginner.  You 
don't  need  high  power,  or  a  tremendous  antenna. 
You'll  never  have  to  peel  the  signals  off  in 
layers  to  get  at  the  fellow  you're  trying  to  work. 
Equipment  is  simple  to  build,  and  easy  to  get 
going.  Plenty  of  operators  have  enjoyed  working 
on  6  with  as  little  as  5  watts  input,  and  the  na- 
tional average  is  probably  well  under  100  watts. 
Transmitters  running  more  than  300  watts  are 
a  distinct  rarity  on  50  Mc.  You  may  want  to 
build  a  converter,  to  get  the  best  possible 
reception,  but  a  first-class  job  can  be  made  with 
as  few  as  two  tubes.  Circuitry  and  adjustment 
procedure  are  of  elementary  simplicity,  as  future 
articles  of  this  series  will  show. 

Propagation  at  50  Mc. 

You'll  have  more  fun  and  work  more  stuff 
on  6  if  you  acquire  at  least  a  nodding  acquaint- 
ance with  the  ionospheric  and  atmospheric 
factors  that  affect  your  coverage.  Knowing  some- 
thing of  what  to  expect,  and  when,  is  at  least 
half  the  battle. 

One  thing  you'll  notice  right  away  is  that 
signal  strength  from  stations  other  than  locals 
varies  with  the  weather,  and  with  the  time  of 
day.    Stronger-than-normal    signals,    at    50    to 


22 


QST  for 


200  miles,  and  occasional  reception  up  to  300 
miles  or  more,  result  from  bending  of  the  trans- 
mitted wave  as  it  passes  through  a  boundary 
between  air  masses  of  differing  temperature  and 
humidity  characteristics.  If  warm  moist  air  over- 
runs cold  dry  air  we  have  the  right  condition 
for  this  kind  of  bending.  It  happens  fairly  often : 
dail}',  in  fact,  in  warm  weather,  especially  in 
areas  adjacent  to  large  bodies  of  water.  Air-mass 
movement  on  a  continental  scale  (the  sort  of 
thing  j'ou  see  recorded  on  the  weather  maps) 
can  produce  this  sort  of  "inversion"  over  very 
large  areas. 

Good  v.h.f.  conditions  lying  along  large-scale 
air-mass  boundaries  can  develop  at  any  season. 
This  helps  keep  life  interesting  for  the  v.h.f.  man 
during  the  winter  months.  A  likely  sign  that 
favorable  factors  are  present  is  the  increasing 
high  cloudiness  that  follows  a  period  of  fair  calm 
weather.  The  barometer  will  be  fairh'  high  and 
steady  preceding  the  good  period,  and  it  is 
probable  that  there  will  be  a  slow-moving  "low" 
somewhere  a  few  hundred  miles  to  the  west. 
Signals  are  usuallj-  strongest  in  the  early  daylight 
hours,  and  around  sundown,  though  varying 
weather  conditions  may  upset  this  schedule. 
Watch  the  weather  maps  presented  dailj'  on 
many  television  stations,  or  check  those  appear- 
ing in  the  newspapers,  and  you'll  soon  develop 
the  knack  of  telling  when  things  are  going  to  be 
better  than  average  on  the  v.h.f.  bands. 

Ionospheric  DX  is  less  predictable,  at  the 
present  state  of  the  art,  but  we  know  in  a 
general  way  when  it  is  most  likely  to  show  up. 
The  most  frequent  form  results  from  the  re- 
flection of  the  wave  by  scattered  areas  in  the  E 
region  of  the  ionosphere,  some  50  miles  above 
the  earth.  It  can  happen  any  time,  but  it  is 
most  frequent  in  the  early  summer  months. 
There  is  a  less-pronounced  period  in  late  Decem- 
ber and  early  January. 

Sporadic-£^  skip,  as  it  is  most  commonly 
known,  is  one  of  the  6-meter  operator's  real 
thrills.  Signals  appear  suddenly,  out  of  nowhere, 
and  frequently  rise  to  amazing  strength.  Thej^ 
may  staj^  in  for  only  a  few  minutes  at  a  time, 
or  the  band  maj'  remain  open  for  hours.  Oc- 
casionally in  June  or  July  there  may  be  DX 
signals  around  the  clock.  Signals  are  commonly 
heard  over  distances  of  500  to  1200  miles,  though 
dense  ionization  may  bring  the  minimum  skip 
distance  down  to  300  miles,  or  even  less.  Multiple 
reflections  also  e.xtend  the  range  to  as  much  as 
2500  miles,  on  occasion.  It  is  thus  possible  for 
an  alert  50-Mc.  operator  to  work  all  states,  and 
at  least  ten  have  qualified  for  the  special  certifi- 
cate award  that  ARRL  issues  in  recognition  of 
this  accomplishment. 

Reflections  from  the  auroral  region  offer  an- 
other means  of  working  beyond  the  normal 
range  on  50  Mc.  If  j^ou  see  "Northern  Lights" 
on  a  clear  night,  aim  j'our  6-meter  array  in  that 
direction  and  you're  likely  to  hear  the  weirdest- 
sounding  signals  3'ou  ever  imagined.  Voice  or 
any  other  form  of  modulation  is  sure  to  be  badly 
distorted,  and  may  be  completely  unreadable, 


making  c.w.  the  only  usable  means  of  communi- 
cation. Auroral  conditions  develop  most  often 
in  the  early  evening,  but  they  may  show  before 
sundowTi,  so  you  have  to  watch  radio  conditions 
to  catch  all  the  opportunities.  The  distances  over 
which  auroral  effects  are  noted  extend  from  a  few 
miles  to  as  much  as  800. 

Around  the  peak  of  the  sunspot  cycle  there 
is  a  chance  of  50-Mc.  DX  of  world-wide  pro- 
portions. Between  1946  and  1950  many  trans- 
atlantic and  transpacific  contacts  were  made,  and 
North  American  stations  worked  several  South 
American  countries  on  6.  It  may  seem  hard  to 
believe,  in  these  days  when  28  Mc.  is  dead  most 
of  the  time,  and  21  Mc.  only  partially  open,  but 
working  international  DX  was  quite  a  sport  on 
50  Mc.  in  the  spring  and  fall  months  of  those 
years.  Distances  of  2500  to  5000  miles  were 
common,  and  contacts  were  made  with  as  little 
as  3  watts  input!  An  almost  unbeatable  record 
of  10,500  miles  was  set  in  1947. 

So  you  see  that  just  about  all  the  factors 
that  affect  lower  frequencies  influence  50-Mc. 
communication  at  times,  and  in  addition,  it 
responds  to  weather  variations.  As  propagation 
seldom  remains  stable  for  more  than  a  few  hours 
at  a  time,  it  is  hard  to  say  just  what  "normal" 
conditions  really  are.  Perhaps  it  is  better  to  talk 
in  terms  of  minimum  distances,  rather  than 
average,  if  we  want  to  establish  what  the  po- 
tential 6-meter  operator  may  be  able  to  work. 
Suppose  you're  going  to  run  50  to  100  watts 
input.  You  don't  have  room  for  a  big  tower,  so 
you're  planning  to  put  up  a  2-  or  3-element 
rotary  that  won't  stand  out  among  the  TV 
antennas.  It  will  be  no  more  than  50  feet  above 
ground  —  perhaps  less.  What  can  you  expect  to 
do  on  6? 

Unless  you're  completely  surrounded  by  nearbj^ 
hills  much  higher  than  your  antenna,  you  should 
be  able  to  work  at  least  50  miles  consistent!}', 
with  stations  similarly  equipped.  If  you  have  a 
reasonably  open  location  (not  necessarilj-  a  high 
one),  so  that  your  antenna  "sees"  a  horizon 
several  miles  away,  your  reliable  operating  radius 
should  be  at  least  100  miles,  and  you  should  get 
in  some  contacts  up  to  perhaps  200  miles  when 
weather  is  favorable.  If  you  have  a  hilltop  site, 
and  plenty  of  hams  seem  to  manage  it,  you  will 
find  it  possible  to  keep  reliable  schedules  with 
well-equipped  stations  out  to  200  miles  or  more, 
and  300-mile  stuff  will  not  be  uncommon.

of  your  location.  In  either  department,  the  sharp 
operator  in  a  "poor"  v.h.f.  location  may  do  just 
about  as  well  as  his  more  fortunately-situated 
fellows. 

Equipment 

The  50-Mc.  transmitter  need  not  he  threat  1\- 
different  from  gear  used  on  lower  bands.  Most 
currently-used  tubes  work  well  on  50  Mc,  and 
only  a  little  attention  to  layout  is  needed  to 
make  an  efficient  r.f.  section  for  6.  Any  recent 
edition  of  The  Radio  Amateur's  Handbook  will 
give  you  practical  ideas,  or  there  are  units  you 
can  duplicate,  part  for  part,  if  you  like. 

Receiving  may  be  more  of  a  problem.  As  most 
hams  buy,  rather  than  build,  when  it  comes  to 
receivers,  the  lack  of  suitable  ready-made  gear 
has  kept  quite  a  few  hams  from  enjoying  6  in 
recent  years.  Several  commercial  receivers  have  a 
"50-Mc.  band"  but  few  of  them  do  a  passable 
job.  There  are  present  indications  of  a  change 
for  the  better,  but  you  may  have  to  build  your 
own  "front  end"  if  j'ou  want  to  receive  as  far 
as  you  can  transmit.  If  your  receiver  is  the  single- 
conversion  variety,  and  nearly  all  more  than  two 
years  old  are,  it  probably  won't  "have  it"  for 
50-Mc.  work,  without  a  converter.  A  few  double- 
conversion  jobs  on  the  market  show  fair  50-Mc. 
performance,  but  all  are  in  the  higher-priced 
brackets.  If  your  receiver  is  low-  or  medium- 
priced  you're  sure  to  need  a  converter,  even 
though  the  receiver  dial  does  indicate  50-Mc. 
coverage. 

Fortunately,  construction  and  adjustment  of 
a  50-Mc.  converter  need  frighten  nobody.  And 
if  your  receiver  is  in  good  working  condition  it 
doesn't  make  too  much  difference  if  it  happens 
to  be  15  years  old,  or  one  of  the  low-budget 
jobs.  The  Handbook  can  be  your  guide  as  to 
converter  designs,  and  we  have  some  new  units 
in  the  works  here  in  the  ARRL  lab.  They  will 
be  tailored  to  the  beginner's  needs,  and  you'll 
be  seeing  them  soon  in  QST. 

The  antenna  is  probably  the  most  important 
part  of  the  50-Mc.  station.  Investment  in  the 
antenna  system  will  yield  greater  returns  than 
time  and  money  spent  elsewhere  in  the  6-meter 
station.  You  can  work  a  radius  of  25  miles  or 
so  with  an  indoor  folded  dipole,  but  you'll 
never  know  how  much  fun  the  band  can  be  until 
you  put  up  something  better.  In  these  days  of 
inexpensive  TV  rotators  and  arrays  on  every 
roof,  a  6-meter  beam  is  within  the  reach  of 
almost  everyone.  Whatever  you  put  up  for  an 
antenna,  make  it  rotatable.  There  is  nothing 
more  unsatisfactory,  in  most  locations,  than  a 
fixed  antenna.  It  will  always  be  aimed  in  the 
wrong  direction  when  your  friends  on  6  are 
working  something  good! 

Even  if  you  plan  only  a  single  element,  arrange 
to  be  able  to  turn  it.  A  dipole  works  surprisingly

well  if  it  can  be  kept  broadside  to  the  desired 
incoming  signal.  But  if  you  can  put  up  a  good 
dipole,  with  provision  for  rotation,  you  can  add 


at  least  one  parasitic  element.  That  first  one 
really  pays  off,  too,  and  even  a  2-element  beam 
will  do  a  real  job  for  you,  if  it  is  fed  properly. 
Additional  elements  are  worth  the  effort,  too, 
if  you  can  manage  them.  Make  the  antenna  as 
big  and  as  high  as  you  can.  Your  Handbook 
gives  you  all  the  necessary  design  details. 

Problems  —  If  Any 

With  our  band  at  50  to  54  Mc,  and  TV 
Channel  2  at  54  to  60  Mc,  it  is  rough  on  the 
6-meter  man  when  his  community  gets  a  Channel 
2  TV  station.  It  may  be  rougher  in  a  Channel  2 
fringe  area.  TV  receivers  are  just  not  capable 
of  slicing  it  that  thin.  But  there  are  many 
areas  that  do  not  have  Channel  2  service,  and 
for  these  the  50-Mc.  band  is  relatively  free  of 
TVI  problems.  If  moderate  power  is  used  and  the 
rig  is  designed  so  as  to  prevent  harmonic  radi- 
ation '  there  is  a  very  good  chance  of  avoiding 
TVI  entirely. 

If  some  is  encountered  it  is  easy  to  cure. 
The  writer  has  operated  on  50  Mc.  consistently 
since  long  before  television,  much  of  the  time 
with  high  power,  without  running  into  any  TVI 
problems  that  could  not  be  solved  readily.  If 
you  live  in  a  40-family  apartment  house  you  maj' 
not  want  to  try  it,  but  if  you  can  manage  100 
feet  clearance  from  your  neighbors'  TV  antennas, 
operating  on  6  should  pose  no  threat  to  neighbor- 
hood peace.  You  may  have  to  put  a  300-ohm  stub 
on  here  and  there,  but  unless  you're  blesssd  with 
Channel  2  you'll  need  nothing  more  pretentious 
in  the  way  of  TVI-preventive  measuies  than  a 
few  scraps  of  Twin-Lead.  Even  in  Channel  2 
areas,  the  problem  is  by  no  means  hopeless,  as 
W2IDZ  showed  recently  in  QST.- 

Here,  then,  is  the  50-Mc.  picture,  presented 
in  the  frankest  possible  terms.  As  one  of  the 
band's  long-time  regulars,  the  writer  feels  — 
with  several  hundred  other  die-hards  —  that 
anyone  who  has  not  given  6  a  real  try  has  missed 
one  of  the  gi-eat  experiences  that  ham  radio  has 
to  ofYer.  We  hope  that  in  years  to  come  many 
newcomers  will  share  this  opinion.  To  help  them 
along  the  way,  we've  been  working  for  some  time 
on  several  transmitters  and  receivers  designed 
especially  for  the  beginner.  You'll  be  seeing 
them  in  forthcoming  issues  of  QST.

Circuit 

.\ii  inspection  of  the  circuit  diagram.  Fig. 
1,  will  show  you  that  there  is  nothing  new  and 
tricky  here.  The  front  end  of  the  transmitter 
consists  of  Don  Mi.x's  "Bandbox,"'  shghtly 
modified  electrically  by  the  addition  of  another 
switch  section  so  that  if  a  VFO  with  160-meter 
output  is  available,  that  VFO  output  can  be 
applied  to  the  grid  of  the  final  tube.  It  was  also 
inodified  mechanically  to  fit  this  particular  lay- 
out. The  final  tube  is  the  popular  6146,  with  a 
variable  inductor  and  pi  network  so  that  no 
coils  have  to  be  changed  when  shifting  bands. 

TVI  has  been  reduced  to  a  minimum  by 
comi)lete  shielding,  bj^  the  use  of  shielded  wire 
for  all  d.c.  leads,  and  by  appropriate  by-passing 
of  all  leads  leaving  the  chassis.  A  coil  shield 
covers  the  meter,  and  the  only  possible  "hole" 
is  the  socket  on  the  rear  panel  for  the  power  plug. 
But  all  leads  there  are  by-passed  and  no  r.f. 
can  be  detected  leaking  out. 


The  amplifier  is  set  in  a 
"dish"  (see  Fig.  3)  in  a  cut-out 
section  of  the  two  back-to- 
back  chassis.  This  view  is 
looking  down  into  the  trans- 
mitter with  the  top  plate  off. 
The  tubes  in  the  "Bandbox" 
exciter  section  are  at  the  left.

Layout 

Looking  at  the  transmitter  from  the  front, 
the  exciter  portion  occupies  the  left  half  of 
the  chassis,  while  the  final  occupies  the  right 
half.  The  panel  controls,  reading  from  left  to 
right,  are  the  handswitch  controlling  the  exciter, 
exciter  tuning,  the  meter  switch,  plate  capacitor 
for  the  6146,  variable  inductor  for  the  6146,  and 
the  switch  for  the  loading  capacitors.  The  meter 
is  in  the  upper  center,  while  a  chart  in  the  upper 
left  attempts  to  balance  the  e.xtra  counter  dial 
on  the  variable  inductor. 


Along  the  rear  of  the  chassis  are  the  coax 
connector  for  VFO  input,  the  power  socket,  and 
the  coax  connector  for  r.f.  output. 

Looking  at  the  top  of  the  transmitter,  we  see 
the  tulies  for  the  exciter  standing  at  attention 
at  the  left,  with  the  shield  can  for  the  meter 
front  and  center.  The  final  is  set  in  a  "dish," 
with  the  variable  inductor  right  in  the  center, 
the  tube  left  rear,  variable  capacitor  left  front, 
and  loading  capacitor  switch  at  the  right.  In 
order  to  obtain  better  operation  at  10  meters 
and  in  order  to  cover  160  meters  at  all,  induc- 
tance Lg  is  broken  up  into  three^sections.  Lga

The  circuit  of  the  power  supply  used  in  con- 
junction with  the  transmitter  is  shown  in  Fig.  2. 
A  pair  of  816s  was  used  originally,  but  thej^ 
generated  a  hash  on  80  meters  which  would  not 
clear  up  with  any  of  the  combinations  of  filter 
tried,  and  so  thej'  were  replaced  with  the  single 
5R4GY.  The  clamp  circuit  is  one  that  has  been 
described  several  times  in  recent  issues  of  QST. 

The  VFO  that  has  been  used  with  this  rig 
has  a  couple  of  6AG7s  in  a  Clapp  oscillator  and 
buffer,  and  is  iveyed  with  a  MilHsec  relay  ac- 
cording to  Goodman. - 

Construction 

In  order  to  obtain  complete  shielding,  two 
3  X  8  X  17-inch  chassis  were  bolted  together 
back  to  back,  or  top  to  top,  depending  upon  how 
you  look  at  it.  The  Bandbox  exciter  is  then

panel.  The  cut-out  for  the  final  is  7  inches 
wide  and  8  inches  long,  and  a  shelf  to  support 
the  components  for  the  final  hangs  down  2^ 
inches    below    the    cut-out.    Fig.    3    shows    the

dimensions  of  this  shelf,  as  its  configuration  is 
not  clearl}-  shown  in  the  photos. 

The  6146  is  mounted  on  a  small  bracket  at 
the  left  rear  of  the  shelf.  Capacitor  Cg  is  in 
front  of  the  tube,  mounted  on  a  couple  of  small 
aluminum  spacers  so  that  its  dial  will  be  in  line 
with  the  others.  Between  Cs  and  the  tube  are 
RFC'i  and  C7.  Parasitic  choke  L5  is  supported 
between  the  junction  of  C-j-RFCi  and  the  tube 
plate  cap.  Cu  is  connected  to  the  high-voltage 
lead  at  the  power  plug  where  the  lead  leaves  the 
chassis.  Coil  Lba  shows  up  poorly  in  the  photos, 
but  is  supported  by  a  National  GS-3  pillar 
insulator  (mounted  to  the  left  and  in  front  of 
the  variable  inductor)  and  the  terminal  of  the 
variable  inductor.  It  is  at  right  angl(>s  to  Lisb, 
the  roller  coil. 

At  the  right  rear  edge  of  the  variable  inductor 
is  the  GS-3  insulator  which  normally  supports 
Lgc,  and  directly  behind  that  is  the  safety  choke 
RFC'I.  Switch  5-2  is  at  the  far  right:  one  sjction 
switches  the  loading  capacitors  which  are  clus- 
tered to  the  rear  of  the  switch  and  the  other 


section  shorts  out  Lee  on  all  bands  other  than 
160  meters,  as  mentioned  earlier.  Just  barely 
visible  in  the  photograph  is  the  coil  portion  of 
the  harmonic  trap  L-,Cu. 

Top  and  bottom  plates  are  8  by  17  inches,  and 
are  secured  by  l^-inch  6-32  screws  spaced  every 
2  inches  around  the  edges  of  the  chassis.  The 
chassis  material  is  rather  light,  but  if  care  is 
used  it  may  be  drilled  and  tapped  with  good 
results.  Just  don't  tighten  up  on  the  6-32s 
too  strenuously.  The  7-inch  panel  is  held  to  the 
chassis  by  the  various  tuning  controls  and  panel 
bearings,  and  by  the  bolts  which  hold  the  meter 
and  meter  shield  in  place.  The  meter  shield  is 
an  ICA  No.  1540  coil  shield,  cut  down  so  that 
it  is  only  2  inches  high. 

The  only  other  piece  of  mechanical  work 
that  is  at  all  unusual  is  the  counter  for  the 
variable  inductor.  At  the  time  this  transmitter 
was  conceived  the  only  counters  obtainable  took 
up  more  room  on  the  panel  and  behind  it  than 
was  available,  and  so  a  homemade  counter  was 
contrived  using  Boston  gears  Nos.  G142  and 
G148,  some  G29  pinion  wire,  two  panel  bearings, 
a  couple  of  aluminum  brackets,  and  a  surplus 
dial.  Fig.  4  shows  the  method  of  assembly.  The

oounter  dial  on  the  panel  was  taken  from  a 
surplus  tuning  unit,  and  was  mounted  by  drilling 
and  tapping  the  shaft  on  which  the  G148  spur 
gear  was  mounted.  Ineidentally,  the  spur  gears 
come  with  hubs  whieh  have  to  be  drilled  and 
tapped  in  order  to  allow  fiisteiiing  to  the 
shafts. 

Now  for  a  few  miscellaneous  notes  on  the 
construction  and  wiring.  You  should  tlo  all 
necessary  by-passing  and  other  wiring  at  the 
6146  tube  socket  before  mounting  it  and  its 
bracket  in  position.  There  is  not  enough  room 
to  get  down  between  it  and  the  edge  of  the 
shelf  with  any  ordinary  soldering  iron.  A  series 
of  14-inch  holes  is  drilled  Ix'low  th(>  tube  in  the 
shelf,  in  line  again  in  the  bottom  plate  and  in 
the  top  plate,  to  provide  ventilation  for  the  6146. 
The  now-standard  practice  of  using  shielded 
wiring  on  the  d.c.  leads  is  followed  in  this  rig, 
with  plenty  of  bonds  to  the  chassis  at  convenient 
points.  The  meter  shunts  were  wound  by  trial 
and  error,  using  a  rheostat,  battery,  and  full- 
range*  milliammeters  to  determine  the  shunts 
needed.  The  shunt  for  measuring  exciter  current 
extends  the  10-ma.  range  of  the  meter  to  100 
ma.,  while  the  shunt  for  the  6146  ])late  current 
extends  the  range  to  200  ma.  No  shunt  is  needed 
for  the  6146  grid  curnMit.  Th(>  panel  markings 
are  Tekni-Cals. 

Operation 

Adjustment  of  the  exciter  has  been  fully 
covered  by  Mix,  and  so  need  not  be  detailed 
further.  It  might  be  mentioned,  however,  that 
the  exciter  worked  right  from  the  moment  plate 
voltage  was  first  applied,  and  the  process  of 
aligning  it  was  very  simple.  Thus,  if  the  speci- 


fications in  the  original  article  are  followed  you 
will  have  no  difficulty  with  that  part  of  the 
circuit. 

In  the  final  the  harmonic  trap  is  adjusted 
t)y  resonating  the  LtCh  combination  to  your 
local  TV  channel.  Do  this  by  shorting  the  coax- 
connector  terminals  and  coupling  L^  to  a  grid- 
dip  meter.  In  my  case  L^  consists  of  three 
turns  of  No.  18  wire  wound  to  a  34-inch  diameter, 
while  T'ls  is  100  tifji.  L-  was  then  adjusted  until 
the  circuit  hit  Channel  6. 

The  values  of  the  loading  condensers  were 
picked  by  going  back  to  the  early  articles  on 
the  pi  network.  I  had  to  make  no  further  adjust- 
ment, and  so  in  this  case  blind  luck  triumi)hed 
over  science. 

The  80-meter  l)and  is  tuned  with  all  of  Len 
in  the  circuit,  40  is  tuned  with  about  12  turns  of 
LfiB  in  the  circuit,  20  meters  with  about  7  turns, 
and  15  meters  with  about  5  turns.  For  10  meters, 
Lee  is  shorted  out  altogether  by  running  the 
contactor  all  the  way  to  the  end  of  the  coil. 
These  adjustments  could  vary  depending  upon 
what  kind  of  load  your  transmitter  has  to  feed. 

A  word  of  caution  about  the  6146  is  in  order. 
It  appears  that  this  tube  is  particularly  sus- 
ceptible to  overloads,  and  so  you  should  exercise 
care  not  to  allow  it  to  operate  off-resonance; 
otherwise,  you  will  soon  end  up  with  a  tube 
exhibiting  grid  emission. 

This  rig  has  been  used  by  itself,  with  an 
antenna  coupler,  as  a  very  nifty  low-power 
transmitter.  It  was  used  with  success  during 
the  1953  and  1954  SS  contests,  and  the  TV 
receiver  in  the  next  room  never  knew  it  was  on 
the  air.  It  has  also  been  used  to  drive  a  pair  of 
triodes  running  a  kilowatt  input.

The  voltage  regulator  tubes,  clamp  tube  and 
bias  battery  are  at  the  right-hand  end  in  this 
view.  The  "plate  switch"  socket  beside  the 
ILS-volt  connector  on  the  chassis  lip  is  wired 
in  parallel  with  the  front-panel  plate  switch 
and  is  for  remote  control  of  the  plate  voltage.

A  One-Tube  Receiver  for  the  Beginner 

The  6U8  in  a  Regenerative  Receiver 
BY  LEWIS  G.  MCCOY,  WIICP 


•  The  easiest  way  to  break  into  the  re- 
ceiver-construction game  is  to  build  a 
regenerative  receiver.  Flere  is  a  "one- 
tube"  regenerative  receiver  that  is  easy 
to  put  together  and  has  performance 
equal  to  any  in  its  class.  And,  after  all 
these  years,  it  has  an  honest-to-goodness 
antenna  coupling  circuit. 


JUDGING  from  the  mail  here  at  Headquarters,  it 
would  appear  that  one  of  the  many  questions 
facing  the  newcomer  is  whether  to  bu,y  or 
build  his  first  receiver  and  transmitter.  The 
answer  to  that  depends  on  whether  one  is  in- 
terested in  just  operating  or  in  learning  about 
radio.  If  you  want  to  understand  radio,  the  only 
real  way  to  acquire  experience  is  by  building  your 
own  equipment.  At  least  at  the  beginning. 

This  article  describes  the  construction  of  a 
simple  one-tube  regenerative  receiver  that  will 
fulfill  the  basic  requirements  for  communications 
work.  The  title  of  the  article  states  that  the 
receiver  is  a  one-tube  job.  Actually,  it  uses  two 
tubes  in  one  envelope  —  envelope  meaning  the 
glass  enclosure.  The  6U8  is  a  triode-pentode,  and 
in  this  receiver  the  pentode  section  is  used  as  a 
regenerative  detector  and  the  triode  portion  as 
an  audio  amplifier. 

With  this  receiver  it  is  possible  to  hear  amateur 
and  commercial  stations  in  the  2-  to  20-Mc. 
range.  This  tuning  range  will  enable  the  builder 
to  listen  to  the  two  low-frequency  Novice  bands. 
Also,  if  one  is  interested  in  obtaining  code 
practice,  WlAW,  the  ARRL  Hq.  station,  can  be 
tuned  in  for  its  nightly  code-practice  sessions. 

The  Circuit 

The  circuit  used  in  this  receiver  differs  in  a  few 
places  from  the  usual  regenerative-receiver  cir- 
cuit. For  example,  instead  of  the  usual  small 
antenna-coupling  capacitor  or  inductor,  provision 


was  included  here  for  either  a  series-  or  parallel- 
tuned  antenna  circuit.  This  allows  a  wide  range 
of  coupling  adjustments  to  be  obtained,  as  is 
often  necessary  with  regenerative  receivers. 

Referring  to  Fig.  1,  the  antenna  coil,  Li, 
couples  the  signal  to  the  detector  tuned  circuit 
L2C2C3.  The  capacitor,  C2,  is  larger  than  C3  and 
is  used  as  the  "handset"  capacitor  —  once  Cz 
is  set  for  a  particular  frequency  range,  C'3  is  used 
as  the  "bandspread"  tuning  control.  To  facilitate 
using  manufactured  coils,  the  coil  L2  is  tapped 
to  obtain  a  feed-back  or  "tickler"  winding.  Re- 
generation in  the  detector  is  controlled  by 
changing  the  screen  voltage  obtained  at  the 
potentiometer  Ri.  An  r.f.  filter,  using  two  cap- 
acitors and  an  r.f.  choke,  is  placed  in  the  plate 
circuit  of  the  pentode  detector  to  reduce  r.f. 
appearing  at  the  grid  of  the  triode  audio  ampli- 
fier. Still  further  attenuation  of  r.f.  at  the  grid 
is  obtained  through  the  use  of  a  series  resistor 
and  a  shunt  capacitor  right  at  the  grid  of  the 
audio  stage.  To  save  a  little  money,  the  audio 
coupling  choke,  L3,  is  made  from  an  inter- 
stage audio  transformer  with  the  two  windings 
connected  in  series.  A  high-inductance  choke 
could  be  used  here,  but  the  series-connected 
transformer  does  a  good  job  and  is  less  expensive. 

The  headphones  are  connected  directly  in  the 
plate  circuit  of  the  audio  stage,  and  consequently 
the  plate  voltage  appears  at  the  terminals  — 
you  can  get  an  electrical  shock  here  if  you  aren't 
careful.  Some  receivers  eliminate  this  hazard 
b}^  feeding  the  plate  through  an  audio  choke  and 
coupling  to  the  headphones  through  a  capacitor, 
but  again  in  the  interest  of  saving  a  few  dollars 
this  protective  feature  was  not  included.  In  any 
event,  be  sure  to  use  "high-impedance"  head- 
phones with  this  receiver  —  the  low-impedance 
headphones  that  have  been  available  in  surplus 
will  not  work  well  in  this  particular  circuit. 

Construction 

The  receiver  is  built  on  a  7  X  7  X  2-inch  alumi- 
num chassis,  with  the  power  supply  mounted  on 


Front  view  of  the  receiver  and 
power  supply.  The  control  at  the 
upper  left  is  the  general-coverage 
tuning,  center  is  bandspread,  low- 
er left  the  regeneration  control, 
and  the  bottom  center  the  an- 
tenna trinuncr.

The  leads  from  the  two  capacitors 
are  run  through  rubber  grommets 
to  avoid  shorting  to  the  chassis  top. 


a  separate  chassis.  In  order  to  minimize  hum 
pickup  and  vibration  from  the  power  trans- 
former, it  is  not  advisable  to  mount  the  power 
supply  on  the  same  chassis  as  the  receiver.  It  is 
not  necessary  to  use  alumiimm  chassis  for  the 
two  units,  but  it  does  tend  to  make  a  neater  job. 
The  aluminum  is  easy  to  work  —  a  }/$-  and  H- 
inch  drill,  plus  a  small  rattail  file  and  hack-saw 
blade  being  all  the  tools  that  are  needed  for  the 
job,  although  two  socket  punches  can  be  used 
to  advantage  and  will  save  >'ou  some  work. 

The  first  step  is  to  mount  the  coil  and  tube 
sockets.  They  are  spaced  2  inches  from  the 
sides  at  the  center  of  the  chassis.  Ground  lugs 
should  be  mounted  under  the  nuts  that  hold  the 
tube  socket  and  also  under  the  rear  nut  holding 
the  coil  socket.  Ne.xt,  the  panel  holes  are  drilled. 

Looking  at  the  photograi)h  showing  the  panel 
front,  the  knob  at  the  lower  left  is  the  regenera- 
tion control,  lower  center  is  the  antenna  tiimmer, 


and  the  h(>adphone  tips  are  at  the  lower  right. 
The  knob  at  the  upper  left  is  for  the  general- 
coverage  capacitor,  and  the  one  at  the  right  the 
bandspread  tuning.  The  dial  shown  in  the 
photograph  is  the  National  type  K.  This  has  a 
rim  drive  and  gives  a  desirable  slow  tuning  rate. 

After  the  holes  are  drilled  in  the  panel,  it 
is  held  in  place  against  the  chassis  and  the 
four  holes  along  the  bottom  are  used  as  a  tem- 
plate for  the  chassis  holes.  A  small  right-angle 
bracket  to  hold  the  antenna-trimmer  capac- 
itor is  made  from  a  piece  of  aluminum.  The  hole 
in  the  bracket  should  be  large  enough  to  clear 
the  rotor  of  the  capacitor,  since  both  the  rotor 
and  stator  are  insulated  from  the  chassis.  The 
trimmer  is  mounted  to  the  bracket  by  screws  and 
the  insulated  nuts  on  the  capacitor  frame.  The 
bracket,  tie  points,  and  audio  choke  L3  can  now 
be  mounted  in  place. 

The  two  capacitors,  ('2  and  C3,  should  then  be

ins  ailed  on  the  i)anel.  If  the  Type  K  dial  is  used, 
a  template  is  furnished  with  the  dial  assembly 
to  give  the  correct  i)lacement  points  for  the  dial 
and  rim  drive.  When  the  potentiometer  Ri 
and  the  pin  jacks  are  mounted  in  place,  they 
will  hold  the  panel  to  the  chassis.  Be  sure  to 
insulate  the  pin  jacks  from  the  panel  and  chassis 
with  fiber  washers.  The  through-shaft  bushing 
is  measured  and  cut  to  size,  making  allowance 
for  the  insulated  coupler.  The  receiver  is  now 
ready  for  wiring. 

Wiring 

If  this  is  3'our  first  construction  project,  there 
are  a  few  tips  about  wiring  and  soldering  that  will 
help  you  do  a  good  job.  First,  be  sure  the  end 
of  the  wire  to  be  soldered  is  completely  clean  of 
insulation  or  enamel.  Solder  should  not  be 
depended  on  to  hold  the  connection.  Whenever 
possible,  wTap  the  wire  around  the  connection 
before  applying  solder.  Hold  the  tip  of  the  iron 
against  the  work  until  the  ivork  is  hot  enough  to 
melt  the  solder.  Where  most  beginners  make  a 
mistake  is  in  holding  the  solder  to  the  iron  tip 
and  not  getting  the  connection  hot  enough  for 
the  solder  to  melt  and  hold.  Don't  use  any  more 
solder  than  necessary  to  make  the  connection. 
After  a  connection  is  soldered,  dispose  of  the 
loose  bits  of  solder  and  wire  to  avoid  short 
circuits  to  other  connections. 

Although  it  is  not  shown  in  the  diagram,  it  is 
important  that  a  separate  ground  lead  be  con- 
nected to  the  rotors  of  C2  and  ^3  and  the  lead 
brought  below  the  chassis  to  a  common  grounding 
point  at  the  tube  socket.  This  will  help  make  the 
receiver  stal)le  and  reduce  hand  capacity. 

There  are  five  leads  coming  from  the  inter- 
stage transformer:  red,  blue,  black,  and  two 
green.  The  red  lead  and  green  lead  that  are 
directly  opposite  each  other  are  connected  to- 
gether. After  the  leads  are  soldered  and  taped, 
the  end  of  the  black  lead  is  also  taped.  Thes> 
leads  are  then  rolled  up  and  tucked  in  the  corner 
of  the  c'hassis.  The  remaining  blue  and  green 
leads  then  become  those  used  for  wiring  the  series- 


connected  transformer  into  the  circuit.  One  is 
connected  to  the  junction  of  the  0.01-/uf.  disk 
capacitor  and  the  1-millihenry  r.f.  choke  and  the 
other  lead  is  connected  to  the  B-|-  voltage 
terminal. 

The  Barker  &  Williamson  coils  are  mounted 
on  five-prong  plugs,  although  only  four  of  the 
contacts  are  ussd.  The  link  mounted  at  one  end 
of  the  coil  is  Li  and  the  coil  proper  is  Lo.  To  make 
the  tickler  tap,  a  short  piece  of  hook-up  wire 
approximately  3  inches  long  is  soldered  to  the 
fifth  prong  on  the  plug.  The  piece  of  wire  is 
then  run  through  the  middle  turns  of  the  coil 
and  soldered  to  the  tap  point.  For  the  80-meter 
coil,  the  tap  is  connected  to  the  8th  turn  in 
from  the  link  end.  To  get  the  tap  wire  through 
the  middle  turns  of  the  coil,  it  will  be  necessary 
to  bend  two  or  three  turns  of  the  coil  in  towards 
the  center  of  the  coil.  This  will  provide  sufficient 
clearance  for  the  tap  lead.  It  is  also  necessary 
to  bend  in  the  8th  turn  to  make  the  tap  connec- 
tion. Be  sure  that  none  of  the  bent  turns  touches 
adjacent  turns. 

For  maximum  bandspread  on  40  meters,  it  is 
necessary  to  remove  nine  turns  from  the  40- 
meter  coil.  The  turns  are  taken  from  the  end 
opposite  the  link  end  of  the  coil.  The  tickler  tap 
is  made  on  the  4th  turn  end  from  the  link  end. 

To  bandspread  the  20-meter  coil,  two  turns  are 
removed  from  the  end  opposite  the  link  end.  The 
tap  is  placed  on  the  4th  turn  from  the  link  end. 
In  all  three  coils,  the  tap  lead  should  be  insulated 
where  it  passes  through  the  coil  turns. 

Power  Supply 

The  power-supply  components  can  now  be 
wired.  There  are  two  important  points  that  be- 
gimiers  should  keep  in  mind  when  wiring  the 
supply.  The  first  is  that  the  electrolytic  capacitors 
should  be  wired  with  the  leads  marked  with  a 
minus  sign,  or  negative,  connected  to  the  chassis.

A  Compact  Two-Tone  Test  Generator 

Dual  A.F.  Phase- Shift  Oscillators  for  Modulation  Checking 

BY  ROBERT  F.  TSCHANNEN,*  W9LUO 


•  This  unit  provides  two  audio  fre- 
quencies of  your  choice  for  checking  the 
performance  of  a  linear  amplifier.  In 
ease  you  use  any  of  the  various  two-tone 
techniques  that  require  only  one  audio 
frequency,  or  v\ant  a  lov\--distortion  tone 
for  a.m.  testing,  just  use  one-half  of  the 
circuit  diagram. 


THE  true  performance  of  a  siiigle-sidohand 
exciter  and  linear  amplifier  is  difficult  to  pre- 
dict without  a  few  pieces  of  test  ecjuipment. 
Probably  the  most  important  item  of  test  equip- 
ment for  this  purpose  is  the  oscillograph;  how- 
ever, a  most  useful  and  helpful  companion  unit 
is  a  low-distortion  audio  source  —  better  still, 
a  pair  of  audio  sources. 

The  "Two-Tone  Test  Generator"  described 
below  is  designed  to  provide  two  independent 
low-distortion  audio  test  signals.  The  unit  is  small 
and  compact  and  uses  only  two  tubes.  No  special 
components  are  used  in  the  construction  of  the 
unit.  If  the  generator  is  carefully  made  and  ad- 
justed, the  total  harmonic  distortion  can  be  as 
low  as  U.l  per  cent. 

The  Basic  Circuit 

The  basic  circuit  of  a  phase-shift  oscillator  is 
shown  in  Fig.  1.  Operation  depeiuls  upon  pro- 
ducing 180-degree  phase  shift  in  the  RC  network 
consisting  of  three  capacitors  and  three  resistors; 
sufficient  gain  must  be  produced  by  the  oscillator 
tube  to  make  up  for  the  loss  in  the  network.  For

the  circuit  shown,  a  gain  of  29  times  is  required 
to  sustain  oscillation  (Reference  1,  bibliography). 
The  frequency  of  oscillation  is  determined  by  the 
equation 

10'-  10'2

15.4  RC 


where  R  is  in  ohms  and  C  is  in  micromicrofarads. 
If  the  oscillator  tube  has  a  gain  less  than  29, 
oscillation  will  not  begin;  if  e.xcessive  gain  is  ob- 
tained, appreciable  distortion  may  be  produced. 


Fjg.  I  — The  basic  phase-shift  oscillator  circuit. 

The  phase  shift  through  the  network  at  har- 
monic frequencies  is  always  less  than  180  degrees 
and  in  some  cases  approaches  zero.  This  gives 
rise  to  negative  feed-back  which  reduces  the  gain 
at  harmonic  frequencies;  therefore,  essentially  a 
pure  sine  wave  results.  Maximum  harmonic  re- 
duction occurs  at  the  point  where  the  system  is 
just  able  to  sustain  oscillation. 

General  Circuit  Description 

A  single  (j.\X8  tul)e  is  us;'d  as  oscillator  and 
output  section  for  each  channel  of  the  generator. 
The  pentode  section  functions  as  the  oscillator 


The  two-tone  test  genera- 
tor is  a  compact  and  inex- 
pensive unit  and  provides 
two  audio  signals  of  different 
frequencies  and  equal  ampli- 
tudes for  testing  any  type 
of  s.s.b.  generator.  Distortion 
is  extremely  low  if  proper  care 
is  used  in  adjustment.

proper;  the  triode  section  operates  as  a  cathode 
follower  output.  A  half-wave  selenium  rectifier 
followed  by  considerable  filtering  provides  good 
d.c.  for  the  oscillators.  The  comi)lete  schematic 
is  shown  in  Fig.  2. 

The  lOOO-ohm  controls  in  the  cathode  circuits 
of  the  pentode  stages  are  used  for  controlling  dis- 
tortion. The  controls  permit  adjustment  of  the 
oscillator  tube  gain  to  the  point  where  oscillation 
will  just  be  sustained.  This  also  corresponds  to  the 
point  where  minimum  distortion  occurs.  Two 
additional  lOOO-ohm  controls  in  the  cathodes  of 
the  triode  cathode  followers  provide  control  of 
outputs  from  either  channel.

The  R  and  C  component  values  for  the  net- 
works shown  in  the  schematic  of  Fig.  2  are  ap- 
pro.ximately  correct  for  the  generation  of  400- 
and  1000-cvcle  tones.  Other  values  are  given  in 
Table  I. 

It  is  important  that  the  linearity  of  the  cathode 
follower  l)e  good  since  otherwise  distortion  may 
be  added  by  this  stage.  The  use  of  a  low-u  triode 
tube  such  as  the  triode  portion  of  the  6AN8  per- 
mits the  handling  of  higher  grid  swings  without 
distortion.  Since  the  signal  handled  is  small,  the 
possibility  of  distortion  becomes  negligible.  The 
effective  output  impedance  of  the  cathode  fol- 
lower is  approximately  equal  to  '

gm 
in  shunt  with  the  cathode  resistance  to 
ground  (where  gm  is  the  transcon- 
ductance  in  micromhos).  The  output 
impedance  is  therefore  of  the  order  of 
only  several  hundred  ohms.  This  is  de- 
sirable since  output  signals  may  readily 
be  coupled  into  a  combining  network 
without  appreciable  interaction.  The 
tapped-down  take-off  point  from  the 
plate  of  each  oscillator  tube  reduces 
external  loading  on  the  oscillator  and

also  reduces  the  output  level  to  the  point  where 
the  cathode-follower  grid  circuit  can  handle  the 
signal  without  distortion. 

When  used  for  lowest  distortion,  the  output  of 
either  channel  is  of  the  order  of  1  to  1.5  volts 
r.m.s.  Output  levels  of  8-10  volts  r.m.s.  are  ol)- 
tainahle  if  a  few  per  cent  distortion  is  tolerable. 
The  increased  output  capability  is  obtained  by 
readjusting  the  oscillator  cathode  resistance. 

The  total  "B"  current  drain  of  both  oscil- 
lators and  output  stages  is  about  16  ma.  Line- 
voltage  variations  do  not  greatly  influence  the

oscillator  frequency;  therefore  voltage  stabiliza- 
tion is  not  required.  Larger  screen  by-pass  and 
coupling  capacitors  do  not  add  particularly  to  the 
performance  of  the  unit  since  fixed-freciuency 
operation  is  used. 

Typical  voltage  readings  taken  with  a  d.c. 
v.t.v.m.  are  as  follows: 

1)  B+  at  output  of  filter  =  -f  120  to  -(-130 
volts. 

2)  E'sg  =  -f30  to  +40  volts. 

3)  Ef,  =  -f-55  to  -1-80  volts. 

4)  Ek  (pentode)  =  0.2  to  0.3  volt. 

5)  Ek  (triode)  =  6  to  7.5  volts. 

Construction 

The  chassis  layout  of  the  phase-shift  oscillator 
is  not  critical.  The  entii'e  unit  is  constructed  on  a 
5  X  7  X  l3/2-iiich  chassis.  The  grid  leads  of  the 
oscillator  tubes  are  preferabl.y  kept  short  and 
dressed  away  from  a.c.  supply  and  filament 
leads.  One  side  of  each  filament  of  the  6AN8 
tubes  is  grounded.  The  photographs  of  the  chassis 
will  assist  the  builder  in  making  a  suitable  lay- 
out. The  small  power  transformer  is  capable  of 
supplying  as  many  as  four  individual  oscillators. 
If  desired,  a  6X4  rectifier  maj-  be  substituted  in

place  of  the  selenium  rectitier;  in  this  case  the 
330-ohm  1-watt  current-limiting  resistor  in  series 
with  the  rectifier  may  be  removed. 

Miniature  silver  mica  capacitors  were  used  in 
the  phase-shift  networks  for  compactness;  how- 
ever, conventional  micas  may  be  used  success- 
fully if  space  is  available.  The  coupling  capacitors 
Ci  and  Cs  may  be  Hi-K  disk  ceramic  or  paper 
types.  Components  for  the  phase-shift  network 
are  mounted  on  terminal  strips  or  boards  for 
rigidity  and  neatness.  The  capacitors  (\  through 
Cs  are  not  visible  in  the  bottom  view  since  they 
are  beneath  the  terminal  strips  which  are  located 
on  each  side  of  the  chassis.  The  controls  R\  and 
/?2  are  located  on  each  side  of  the  electrolytic 
filter  cai)acitor.  The  output  controls,  a.c.  switch, 
and  output  tip  jacks  are  on  the  front  flange  of 
the  chassis.  The  layout  shown  will  provide  good 
accessibility  to  nearly  all  components. 

Adjustment  &  Checking 

After  the  wiring  has  been  completed  aiul 
checked  the  unit  may  be  turned  on  and  each  out- 
put observed  on  a  'scope.  If  no  output  appears, 
adjust  the  cathode  resistor  of  the  oscillator  to 
just  slightly  beyond  the  point  where  oscillation 
starts. 

With  the  values  of  cathode  resistances  shown 
on  the  schematic,  it  should  normally  be  possible 
to  stop  oscillation  near  one  end  of  the  control  and 
produce  high  (but  slightly  distorted)  output  near 
the  other  end  of  the  control.  At  the  point  where 
the  distortion  becomes  noticeable,  the  wave  will 
usually  have  an  appearance  similar  to  that  shown 
in  Fig.  3A  or  3B,  which  indicates  even-harmonic 
distortion  (principally  second).  If  a  distortion 
meter  or  wave  analyzer  is  available  it  will  be 
simple  to  adjust  each  cathode  control  to  the 
point  where  lowest  distortion  is  obtained.  Since 
such  equipment  is  seldom  available  to  the  ham 
or  experimenter,  a  reasonable  means  of  minimiz- 
ing the  distortion  is  to  apply  the  signal  under  test 
to  the  vertical  plates  of  a  'scope  and  adjust  the 
horizontal  sweep  speed  until  a  pattern  similar  to 
Fig.  3C  is  obtained.  The  distortion  control  can 
now  be  rotated  until  dimensions  A'  and  Y  are  as 
nearly  equal  as  possible  (see  Fig.  3D).  In  other 
words,  if  A'  and  Y  are  made  equal,  an>'  asym- 
metry due  to  second  harmonic  distortion  is 
negligible.

The  All-Electronic  "Ultimatic"  Keyer 


Part  II— How  It  Works 

BY  JOHN  KAYE,*  W6SRY 


•  Part  I  {QST.  April.  1955)  of  this  article 
descriljecl  >vhat  I  lie  key  does  and  how  it 
can  he  hiiilt.  Here  is  the  evplanation  of" 
the  eireiiits  and  pertinent  test  data. 
Part  I  is  required,  since  it  carries  the 
circuit  diagram. 


THE  electronic  Ultimatic  is  best  considered 
as  tAvo  separate  units,  a  code  generator  and 
a  selector-memory-sequencor  (SMS).  The 
generator  is  composed  of  a  time  base,  two  charac- 
ter-generating triggers,  and  a  relay-control  tube 
or  an  optional  d.c. -output  tube  for  direct  control 
of  vacuum-tube  keyers.  The  SMS  comprises  a 
twin-lever  kej-,  two  memories,  two  interlocked- 
sequencor  circuits,  two  multiple-character  hold- 
ing circuits,  and  two  sequence-seizure  circuits. 
I'his  SMS  structure  is  completely  symmetrical. 
One  side  only  will  be  discussed.  Each  paragraph 
concerning  it  can  also  serve  to  describe  the  other 
side  by  substituting  "dot"  for  "dash"  and  vice 
versa  and  considering  the  corresponding  circuit 
components.  Refer  to  Part  I  for  the  circuit 
diagram.  To  extend  the  stability  range,  grid- 
current  loading  is  used  in  several  places.  For  this 
reason,  some  of  the  voltages  to  be  cited  will  differ 
from  those  calculated  from  straight  voltage- 
divider  action  of  resistor  strings. 

Time  Base 

The  multivibrator,  F1F2,  generates  a  suffi- 
ciently-square wave  at  its  cathodes  from  which 
C^Ri  differentiates  alternate  positive  and  nega- 
tive pulses  for  operation  of  the  generator  triggers. 
The  "mark/space"  ratio  of  this  type  of  oscillator 
has  been  found  to  be  substantially  independent 
of  plate  voltage  over  a  wide  range,  and  conse- 
quentl}',  no  voltage  regulation  is  required.  The 
elevated  grid  return  of  Vi  provides  a  mark/space 
ratio  of  45/55  with  R3  at  ground,  increasing  to 
90/10  before  failure  as  the  arm  is  moved  toward 
the  cathodes.  A  capacity  of  0.05Aif.  at  C'l  gives 
a  minimum  speed  below  5  w.p.m.  and  a  maximum 
above  100.  Heaven  forbid  anyone  turning  it 
loose  on  me! 

Relay  Output 

During  spacing,  the  relay  is  energized  because 
the  grid  of  F3  is  held  at  ground  potential  at 
the  junction  of  R12  and  R13.  The  normal  "back" 
contact  is  used  to  key  the  external  circuit.  On 
"mark"  the  junction  of  R12  and  R13  drops  to  — 15 
volts,  cutting  off  F3.  Relatively  heavy  spring 
tension  on  the  relay  minimizes  armature  travel

time.  WTien  the  grid  of  V3  returns  to  ground 
potential  for  spacing,  the  current  through  V3 
is  sufficient  to  open  the  contact  promptly.  Slower 
armature  travel  at  this  time,  caused  by  the  stiff 
spring,  is  of  no  consecjuence.  With  0.004-inch 
armature  travel,  this  method  of  relay  operation 
results  in  practically  zero  variation  in  the  mark/ 
space  ratio  to,  fantastic  as  it  may  sound,  well 
above  100  w.p.m. 

Idle  Code  Generator 

P'sFe  and  FyFg  are  cathode-coupled  triggers, 
with  Ve  and  F7  conducting  in  the  idle  condition. 
Voltages  of  4-15  and  -|-12  stand  on  Ry  and  R^, 
respectively.  \Vhen  the  output  is  to  remain 
spacing,  both  sequencers,  Fio  and  Fu,  are  cut 
off,  with  cathodes  held  at  -|-1.7  and  -f-.9  by  R22 
and  i?23,  to  compensate  for  the  negative  contact 
potentials  in  the  control  clampers  Di,  D2  and  F4. 
Positive  pulses  from  C2Ri  are  clamped  at  -|-.9  to 
the  grid  of  Vs  by  D2  and  Rm.  The  junction  of 
i?io  and  Rn  holds  the  grid  of  F4  at  its  cathode 
potential  of  -|-1.7,  clamping  positive  pulses  to 
the  grid  of  F5  at  4-2.2  volts.  These  pulse  ampli- 
tudes are  too  low  to  affect  the  triggers.  Negative 
pulses  are  not  affected  by  the  dot  control  VaRq, 
but  are  grounded  out  by  DiRu. 

Dot  Generation 

When  the  output  is  to  be  a  dot,  Fio  is  made 
conductive  by  SMS  action,  establishing  -|-10 
volts  at  Rii-  This  effectively  cuts  off  F4,  whose 
grid  does  not  rise  above  -|-8  volts  at  RioRn- 
The  first  succeeding  positive  pulse  from  C^Ri 
rises  to  -flO  volts  at  the  grid  of  F5  to  transfer 
conduction  to  that  tube.  The  resultant  drop 
across  Rs  transmits  a  60-volt  negative  pulse 
toward  the  grid  of  F7  via  C4  and  R^.  This  cuts 
off  F7  and  transfers  conduction  to  Fg.  The 
junction  RnRis  stabilizes  at  —15  volts  to  cut  off 
F3,  releasing  the  relay  for  marking  output. 

The  following  negative  pulse  cuts  off  F5  and 
returns  conduction  to  Fe.  As  F5  cuts  off,  a 
positive  pulse  is  transmitted  via  C4  to  the  grid 
of  F7,  to  return  conduction  to  that  tube.  The 
junction  of  R12  and  R13  returns  to  ground 
potential,  and  F3  pulls  up  the  relay  for  spacing 
output. 

Even  if  the  key  is  held  closed,  with  a  constant 
-t-10  volts  standing  on  R^i,  the  output  cannot 
again  go  to  marking  until  the  next  positive  timing 
pulse,  ensuring  a  full  half  cycle  of  spacing  output 
to  complete  the  dot. 

Dash  Generation 

When  the  output  is  to  be  a  dash,  Fu  is  made 
conductive    by    SMS    action,    and    -|-10    volts 


36 


QST  for 


stands  on  7?25.  The  first  positive  pulse  from 
CiRi  rises  to  +10  volts  at  the  grid  of  Fg,  trans- 
ferring conduction  from  V^  to  V%  and  the  output 
to  marking.  The  following  negative  pulse  toward 
the  grid  of  V's  is  grounded  by  D\,  and  Tg  remains 
conductive. 

Conduction  in  Fg  reduces  the  potential  at 
/?i5  to  +2.2  volts.  The  voltage  at  the  junction 
of  R\Q  and  R\i  drops  to  — O.o  to  cut  off  T'4,  whose 
cathode  now  stands  at  +0.9  volts.  (The  cut-off 
voltage  is  low  because  the  plate  voltage  is  only 
about  10  volts.)  ChRii  delays  this  drop  until  well 
after  the  first  positive  pulse  has  decayed  at  the 
grid  of  F5.  The  second  positive  pulse  can  now  trip 
F5F6  to  Fs  conduction.  Fg  continues  to  conduct, 
of  course.  The  second  negative  pulse  cuts  off  F5, 
which  returns  conduction  to  F7  and  the  output 
to  spacing.  The  output  cannot  again  go  to  mark- 
ing until  the  next  positive  pulse,  ensuring  the 
half  cj^cle  of  spacing  to  complete  the  dash  after 
\}/2  cycles  of  marking  output. 

^Vhen  conduction  is  first  transferred  from 
V^  to  Fs,  a  19-volt  negative  pulse  is  transmitted 
from  the  grid  of  V^  toward  the  plate  of  F5  via 
C4,  but  /?9  limits  it  to  insufficient  amplitude 
to  upset  stable  conduction  in  Vf,.  If  SMS  action 
has  transferred  sequencor  conduction  to  Fn  by 
the  time  of  the  second  positive  pulse  in  the 
dash,  the  elevation  of  the  cathode  of  F4  is 
only  incidental,  since  the  drop  at  RioRn  has 
already  cut  off  F4. 

Automatic  Spacing  Characters 

As  in  the  relay  model,  interletter  and  inter- 
word spacing  characters  are  obtained  by  allowing 
one  or  two  positive  pulses  to  go  by.  Closure  of 
a  key  at  anj'  time  following  a  passed-up  positive 
pulse  produces  marking  output  beginning  at  the 
next  positive  pulse. 

Memory  Actuation 

The  dot-memory  trigger  Fisl'u  idles  with  T'13 
conducting.  This  is  the  opposite  tube  of  the 
pair  from  that  in  the  code  generators,  facilitating 
the  use  of  readily-derived  positive  memoiy- 
clearance  pulses  and  a  simple  sequencing  struc- 
ture. \Miile  idle,  C12  discharges  and  C13  charges 
through  i?3i.  Closure  of  the  dot  key  lifts  the  grid 
of  Fi4  on  charging  current  to  <"i2  to  the  +10-volt 
value  standing  at  Rs-Rss-  C13  discharges  im- 
mediately and  ensures  C12  action  despite  a 
possibly  scratchy  contact  at  the  kej'.  The  com- 
paratively' slow  (2  miUisecond)  charge  rate  of 
Ci3  through  i?3i  prevents  unwanted  memory 
actuation  from  contact  scratch  as  the  key  is 
released.  The  grid  of  F14  rises  from  —13  volts 
and  stabfizes  at  +10  volts  with  F14  conducting. 
The  key  maj'  be  immediately  opened  and  the 
dot  selection  will  be  stored  in  the  actuated 
trigger  until  cleared  by  appearance  of  the  dot 
at  the  output. 

Memory  Clearance 

The  dot  memory  is  cleared  under  control  of 
D^Rsi  b}^  a  positive  pulse  to  the  grid  of  F13, 


generated  by  CnRzs  from  the  T'3  plate  swing  as 
the  output  goes  to  marking.  To  prevent  spurious 
memory  retrip,  Dj  grounds  the  negative  pulse 
generated  as  the  output  goes  to  spacing. 

Only  one  sequencor  tube  can  conduct  at  a 
time.  If  the  output  character  following  the  time 
of  dot  storage  is  to  be  a  previously-selected  dash, 
Vn  conducts  and  onh-  +1.7  volts  stands  at  7?24- 
The  clearance  pulse  toward  the  dot  memory  is 
clamped  to  that  amplitude  by  DsRzi,  insufficient 
to  clear  the  memory.  \Mien  Fio  is  conductive  for 
dot  output,  the  pulse  is  allowed  to  rise  to  +10 
volts  at  the  grid  of  F13  and  return  conduction 
to  1^13  to  clear  the  memory.  The  dash  memory 
^'^isFie  behaves  identically,  with  clearance  under 
the  control  of  VuD^Rsb. 

Sequence  Interlock 

When  the  dot  memory  is  idle  and  the  dot  key 
is  open,   the  junction  of  Rzo  and  R^  applies 

—  18  volts  to  the  grid  of  Fio,  via  R21  and  ^^31, 
to  cut  off  the  tube.  Tripping  of  the  dot  memory 
applies  +10  volts  from  R30R32  toward  the  grid  of 
Fio.  If  Fu  is  being  held  conductive  by  a  positive 
selection  potential  from  the  dash  memory  or 
key,  its  plate  current  through  Ri^  lowers  the 
potential  at  Ri^Rio  to  —7  volts.  The  positive 
potential  directed  toward  the  grid  of  T'lo  by  a 
dot  selected  under  this  condition  is  clamped  by 
D3R21,  and  the  grid  of  Fio  is  held  below  cut-off. 
This  guarantees  prior  transmission  of  an  earlier 
selected  dash.  C7  stabilizes  the  negative  interlock 
voltage  against  spurious  releases  by  plate  voltage 
fluctuations  caused  by  line-voltage  changes  and 
distributed  capacitive  couplings.  This  is  neces- 
sar}'  at  very  low  line  voltages,  where  the  inter- 
lock potential  drops  to  around  —3  volts. 

With  the  dash  memory  clear  and  the  dash  key 
open,  Fii  is  cut  off  by  —13  volts  at  Rs^Rio, 
and  i?i9/?20  stands  at  +12  volts.  This  allows 
the  +10-volt  dot  selection  potential  to  reach 
the  grid  of  Fio  via  R2i-  The  cathode  of  Fio 
rises  to  +10  volts  to  start  a  dot  on  the  next 
positive  time-base  pulse,  and  permits  the  memory 
clearance  pulse  to  reach  the  grid  of  F13.  Con- 
duction through  Fio  and  R27  lowers  i?28^29  to 

—  7  volts,  to  clamp  at  D^Ro^  any  subsequent^ 
selected  dash  until  after  the  dot  starts.  Ad- 
ditionally, by  thus  locking  out  Fn  and  holding 
7^25  and  the  cathode  of  De  at  +0.9  volts,  clearance 
of  the  dash  memory  (when  actuated  after  dot 
storage  but  before  that  dot  starts)  is  prevented. 

For  a  series  of  dots,  the  key  is  held  closed  and 
+  10  volts  from  Rs-  Rz»  holds  Vw  conductive  via 
i?2i  (and  Fu  locked-out)  after  the  dot  memory 
clears  at  the  start  of  the  first  dot,  until  the  key  is 
released  or  the  sequencor  is  "seized"  by  sub- 
sequent actuation  of  the  dash  memory.  The 
similar  structure  of  the  dash  sequencor  behaves 
identicalh'  under  interlock  control  of  the  dot 
sequencor,  to  provide  single  or  multiple  dashes.

Assume  a  dot  and  a  dash,  selected  in  that 
order  before   any  output   starts,  and  the  keys

The  Sonar  CD-2  Transmitter-Receiver 


AS  its  namo  implies,  the  Sonar  C/D-2  was  de- 
/\  signed  especially  for  civil  defense  radio 
-^  •*-  service.  As  one  of  the  few  v.h.f.  amateur- 
band  pieces  of  gear  presently  approved  l)y  the 
Federal  Civil  Defense  Administration  for  match- 
ing funds,  it  is  of  more  than  ordinary  interest. 
To  cjualify  for  FCDA  approval,  v.h.f.  equipment 
must  comply  with  fairly  stiff  specifications  as  to 
frequency  stal)ility  and  selectivity. 

Achieving  the  required  stability  in  the  trans- 
mitter was  probably  no  great  problem;  cr>-stal 
control  and  reasonable  care  in  mechanical  and 
electrical  design  take  care  of  that.  But  adequate 
selectivity  in  a  2-meter  receiver  runs  to  some 
appreciable  complication,  and  when  selectivity 
is  achieved,  oscillator  instability  is  likely  to  be 
something  of  a  headache.  A  glance  at  the  block 
diagram,  Fig.  1,  will  show  how  these  matters  are 
handled  in  the  CD-2. 

The  receiver  uses  ten  tubes.  The  front  end 
has  a  6BK7  series  cascode,  for  low  noise  figure, 
followed  bj'  a  6AK5  pentode.  Self-tuned  coupled 
circuits  are  used  between  the  second  half  of  the 
cascode  and  the  6AK5  grid,  and  between  the 
6AK5  plate  and  the  first  mi.xer.  Coupling  between 
these  circuits  is  adjusted  to  give  the  desired 
flat  response  across  the  band,  and  the  series 
of  circuits  gives  reasonably  high  attenuation 
of  signals  outside  that  band.  Oscillator  stability 
is  assured  through  the  use  of  a  voltage-regulated 
oscillator-doubler  arrangement,  with  a  self-tuneil 
circuit  in  the  doubler  plate  lead,  and  very  light 
coupling  between  the  oscillator  and  doubler. 

Output  from  the  first  niLxer  is  at  10.7  ^NIc, 
and  there  is  one  stage  of  i.f.  amplification  at  this 
frequency.  Then  follows  a  6U8  mixer-oscillator, 


The  Sonar  CD-2  transmitter-receiver  case  is  designed 
especially  for  civil  defense  station  needs.  The  drop  front 
has  a  plywood  insert  to  make  a  writing  surface.  Space 
for  log,  message  blanks,  microphone  cables  and  other 
accessories  is  provided,  and  the  cover  and  front  lock 
together  to  prevent  unauthorized  use. 

the  latter  crystal-controlled,  converting  to  455 
kc.  Two  stages  of  i.f.  at  455  kc.  work  into  a 
conventional  diode-triode  combination  that  per- 
forms the  functions  of  detection,  a.v.c,  noise 
limiting  and  audio  amplifi- 
cation. The  receiver  ends 
up  in  a  6AQ5  power  audio 
stage,  where  a  choice  of 
speaker,  'phones-with- 
speaker,  or  'phones  alone  is 
afforded. 

The  transmitter  line-up 
consists  of  a  12BY7  crystal 
oscillator-tripler,  using  8- 
Mc.  crystals,  a  6AK6  dou- 
bler, a  pair  of  6J6s  in  push- 
pull-parallel  tripling,  and  a 
6252  as  a  straight-through 
amplifier  on  144  Mc.  In- 
ductively-coupled double- 
tuned  circuits  are  used  in 
the  last  three  stages  to 
provide  essentially  flat  re- 
sponse across  the  band  and 
good  attenuation  of  un- 
wanted oscillator-multipli- 
er frequencies.  The  rated

output  of  17  watts  soems  quite 
conservative  and  is  readily  de- 
veloped. 

Modulation  is  supplied  l)y  a  pair 
of  6AQ5s,  driven  l)y  a  12AT7.  A 
Type  Fl  carbon  button  micro- 
phone is  used,  and  there  is  provi- 
sion for  either  push-to-talk  or 
toggle-switch  control  of  the  send- 
receive  operation.  A  small  amount 
of  r.f.  output  is  coupled  off  at  the  antenna  con- 
nection to  an  r.f.  voltmeter  to  provide  for  tuning 
up.  Indication  of  transmitter  tuning  is  shown  on 
a  meter,  which  doubles  as  a  tuning  meter  for 
reception,  and  in  addition  there  is  a  red  jewel 
light  that  indicates  both  output  and  modulation. 
The  circuit  used  for  these  purposes  is  re])roduced 
in  Fig.  2. 

Tuning  &  Adjustment 

In  keeping  with  its  intended  servicr,  the 
CD-2  is  designed  so  that  a  mini- 
mum of  adjustment  is  recjuired 
in  normal  operation.  Alignment 
adjustments  of  both  transmitter 
and  receiver  are  preset,  and  should 
not  require  adjustment  except  in 
case  of  parts  failure  or  other  dam- 
age.  In  the  case  of  the  receiver, 


the  operator  merely  turns  the  calibrated  dial,  and 
adjusts  the  audio  level  to  suit  conditions.  Ma.xi- 
mum  downward  swing  of  the  meter  indicates 
proper  tuning  of  a  signal. 

The  transmitter  has  provision  for  eight  crystal- 
controlled  channels,  selection  being  made  with 
a  single  front^panel  switch.  The  only  tuning 
adjustments  are  the  final  plate  tank  and  the 
antenna  series-tuning  capacitors.  A  front-panel 
"calibrate"  switch  applies  screen  voltage  to 
the  iT\st;il  osrillntor.  when  the  station  is  in  the

"receive"  position,  to  permit  checking  the 
operating  frequencies  and  the  receiver  calibration 
against  each  other.  The  harmonic  from  the 
crystal  oscillator  in  the  144-Mc.  band  is  strong 
enough  to  make  an  appreciable  dip  show  on  the 
tuning  meter  as  the  receiver  is  tuned  across  the 
operating  frequency. 

The  CD-2  housing  and  accessories  are  designed 
for  its  role  as  a  civil  defense  control  station.

Fig.  2  —  Tuning  indicator  circuit  used  for  checking 
transmitter  adjustments  in  the  CD-2.  In  the  complete 
circuit,  the  meter  is  also  switched  to  indicate  strength  of 
the  received  signal. 

The  drop  front  and  hinged  top  lock  together 
with  a  cut  key,  so  that  unauthorized  use  can 
be  prevented.  The  bottom  portion  of  the  case 
has  ample  space  for  log,  message  blanks,  spare 
cables  and  other  small  accessories.  The  front 
cover  has  a  large  plywood  insert,  to  provide  a 
writing  surface  for  field  use.  The  cover  can  also 
be  removed  readily,  to  save  space  in  a  permanent 
installation.  Carrying  handles  are  provided  on 
the  sides  of  the  case.  The  shelf  on  which  the 


chassis  rests  is  copper  plated,  to  provide  good 
contact  with  the  chassis,  and  it  is  made  of 
expanded  metal  for  full  ventilation.  The  front 
panel  has  a  shaded  desk  light  that  can  be  turned 
on  or  off  by  a  toggle  switch. 

The  power  supply  works  on  either  6-volt  d.c. 
or  115-volt  a.c.  input,  separate  cables  being 
plugged  into  a  single  receptacle  on  the  rear 
wall  of  the  chassis.  The  socket  is  reached  through 
a  hinged  door  in  the  back  of  the  cabinet.  Selenium 
rectifiers  are  used,  this  being  the  first  instance 
we've  seen  where  they  have  been  applied  to 
amateur  gear  of  this  power  rating.  The  result 
should  be  superior  regulation,  and  an  appreciable 
saving  in  drain  when  the  rig  is  run  from  a  6-volt 
source.  An  operating  check  of  the  unit  showed  the 
total  drain  from  a  6-volt  storage  battery  to  be  20 
amperes  on  receiving  and  33  on  transmitting. 
Extended  use  with  storage-battery  power  should 
not  be  attempted  unless  a  satisfactory  means  -of 
charging  is  at  hand,  as  output  drops  rapidly  after 
the  first  5  minutes  of  use  from  a  fully-charged 
battery. 

The  manufacturer  supplies  the  CD-series  gear 
for  any  -l.S-megacycle  segment  of  the  spectrum 
from  50  to  180  Mc,  so  a  CD-6  is  also  available 
for  use  in  the  amateur  50-Mc.  band.  Both 
amateur  band  units  may  be  expected  to  find 
considerable  acceptance  in  areas  where  c.d.  plan- 
ning is  well  organized,  and  supported  by  local  or 
state-wide  governmental  agencies.  —  E.  P.  T. 


The  Gonset  6-Meter  Communicator 


IF  lack  of  suitable  ready-made  gear  has  been 
a  factor  in  the  present  rather  low  state  of 
activity  on  the  6-meter  band,  here's  a  com- 
plete package  that  should  go  a  long  way  toward 
injecting  new  life  into  what  could  be  one  of  our 
most  interesting  slices  of  the  r.f.  spectrum.  Cer- 
tainly the  2-Meter  Communicator  has  become  one 
of  the  most  familiar  features  of  the  v.h.f.  scene. 
This  has  come  about  because  it  combines  in  one 
small  convenient  unit  many  features  that  make 
for  pleasant  and  effective  2-meter  work. 

The  new  6-meter  model  is  physically  an  almost 


exact  duplicate  of  the  popular  2-meter  job.  It  is 
built,  insofar  as  possible,  around  the  same  com- 
ponents and  subassemblies  that  are  used  in  the 
2-meter  rig,  and  it  has  the  same  useful  gadgets. 
These  include  a  tuning  eye  that  works  on  both 
transmitter  and  receiver;  a  crystal  spotter,  for 
checking  transmitter  frequency  and  receiver 
calibration;  an  adjustable  squelch,  for  quieting 
the  receiver  during  stand-by  periods;  universal 
power  supply,  for  both  mobile  and  home-station 
use;  the  option  of  either  carbon  or  crystal  micro- 
phone input;  provision  for  use  of  the  audio  system 


The  double-conversion 
receiver  unit,  left,  and 
combined  transmitter  and 
audio  system,  right,  are 
little  more  than  good-sized 
handfuls.

QST  for 


The  6-Meter  Communicator  by  Conset  is  physically 
an  exact  duplicate  of  its  2-nieter  counterpart.  Individual 
adjustment  of  all  transmitter  stages  is  made  through  holes 
in  upper  left  side  of  the  front  panel,  proper  setting  being 
indicated  by  closure  of  the  tuning  eye.  Receiver  has 
squelch-level,  volume  and  noise  limiter  controls,  lower  left. 


for  public-address  work;  and  many  other  features. 
In  addition,  there  are  innovations  that  help 
the  6-Meter  Communicator  cope  with  conditions 
different  in  several  respects  from  those  encoun- 
tered in  2-meter  operation.  The  receiver  is  a 
double-conversion  job,  providing  considerably 
better  selectivity  than  the  single-conversion 
6-Mc.  i.f.  in  the  2-meter  receiver.  The  tuning 
range  is  extended  one  megacycle  below  the  edge 
of  the  band,  permitting  monitoring  of  the  mobile 
services  in  the  49-Mc.  region  for  signs  of  band 
openings.  Enough  use  of  these  frequencies  is 
made  in  most  parts  of  the  country  so  that  some- 
thing will  be  heard  almost  any  time  that  sporadic- 
E  or  /'Vlayer  skip  is  i)resent.  There  is  a  built-in 
low-pass  filter,  connected  permanently  in  the 
antenna  lead,  to  reduce  harmonics  from  the  trans- 
mitter and  spurious  resj)onses  in  the  receiver. 


For  obvious  manufacturing  reasons,  the  trans- 
mitter has  the  same  tube  line-up  as  the  2-meter 
one,  but  there  is  one  less  multiplier  stage.  A 
6CL6  crj'stal  oscillator-multiplier,  with  either 
8-  or  12-Mc.  crystals,  drives  a  12AV7  parallel 
doubler  to  50  Mc.  The  final  stage  is  a  2E26,  de- 
livering an  output  of  about  6  watts.  (We  measured 
better  than  (i  watts  with  a  Micromatch  into  a 
matched  load.)  The  modulator  has  a  12AX7 
amplifier  working  into  a  6V6GT.  This  also  serves 
as  the  receiver  audio  sj'stem. 

The  receiver  front  end  has  a  6BQ7A  cascode 
r.f.  amplifier  and  a  12AT7  mixer-oscillator,  with 
11-Mc.  output.  The  receiver  oscillator  is  on 
the  high  side,  so  there  is  no  problem  with  28- 
Mc.  images.  Mixer  output  is  11  Mc,  and  there 
is  one  stage  of  i.f.  amplification,  a  6BH6,  at 
this  frecjuency.  Then  follows  a  6BE6  converter 
to  15()0  kc.  and  a  6BJ6  i.f.  amplifier.  The  func- 
tions of  detector,  noise  limiter,  a.v.c.  rectifier 
and  first  audio  amplifier  are  combined  in  a  6T8, 
which  feeds  the  audio  system.  A  subminiature 
t)BG7  dual  triode  handles  the  squelch.  Our  noise 
generator  shows  that  the  noise  figure  of  the  6- 
Meter  Communicator  is  better  than  is  required 
for  good  weak-signal  reception. 

The  power  supply  is  identical  to  the  2-meter 
unit,  having  two  6X4  rectifiers,  and  provision 
for  either  6-volt  d.c.  or  115-volt  a.c.  input.  Con- 
nections for  these  two  types  of  operation  are 
made  by  separate  cables  supplied  with  the  unit. 

A  variation  from  the  2-Meter  Communicator  is 
seen  in  the  antenna  furnished.  The  19-inch  whip 
is  replaced  by  a  polyethylene-insulated  half-wave 
Zepp  that  can  be  rolled  up  and  carried  in  a  pocket. 
The  tjuarter-wave  whip  idea  is  less  effective  with 
the  6-meter  rig.  as  there  is  insufficient  metallic 
mass  in  the  cabuiet  to  serve  as  a  ground-plane  at 
this  lower  frequency.  The  manufacturer  also  of- 
fers 6-Meter  vagi  antennas  that  can  be  used 
individually  or  in  stacked  pairs. 

Cabinet  appearance,  power  supply  and  audio 
system  are  identical  to  the  2-Meter  Communi- 
cator. The  6- meter  model  is  supplied  for  either 
6-  or  12-volt  operation.  —  E.  P.  T.

BOARD  MEETING 

In  May  the  Board  of  Directors  of  the  American 
Radio  Relay  League  will  meet  to  examine  the 
record  for  1954,  and  to  come  to  decisions  charting 
a  continuing  course  for  the  future.  The  director  of 
your  division  is  your  voice  in  League  affairs. 
Communicate  to  him  your  views  on  matters  of 
the  day  so  that  he  may  be  informed,  as  is  required 
of  him  in  the  By-Laws,  "as  to  conditions  and 
activities  in  his  territorial  division  and  as  to  the 
needs  and  desires  of  the  members  therein  in  order 
that  he  may  faithfully  and  intelligently  represent 
the  true  interests  of  such  members." 

TECHNICIANS  GET  50  MC. 

In  mid-March  FCC  released  its  decision  in 
Docket  No.  11157,  dealing  with  Technician  Class 
privileges:  the  50-54  Mc.  band  is  opened  to  that 
class  of  license  effective  April  12th;  FCC  dis- 
missed its  proposal  to  open  also  the  144-Mc. 
band  to  Technicians.  The  text  of  the  order  fol- 
lows: 

1.  As  a  result  of  its  consideration  of  petitions  for  rule 
making  filed  by  James  M.  Price  and  Tom  A.  Walker,  the 
Commission  adopted  the  Notice  of  Proposed  Rule  Making 
in  this  proceeding,  and  it  was  published  in  the  Federal 
Register  on  September  11,  1954,  19  FR  5917.  The  Notice 
proposed  amendment  of  Section  12.23(d)  to  permit  opera- 
tion by  Technician  Class  amateur  operators  in  all  amateur 
frequency  bands  above  50  Mc.  which  would  have  the  effect 
of  adding  the  50-54  Mc.  and  the  144-148  Mc.  bands  to  the 
privileges  presently  available  to  the  Technician  Class 
licensee.  The  petitions  of  Messrs.  Price  and  Walker  proposed 
addition  only  of  the  50-54  Mc.  band  to  the  existing  privi- 
leges for  the  Technician  Class  operator. 

2.  Comment  on  the  proposed  amendment  was  submitted 
by  some  18  amateur  organizations  and  over  125  amateurs 
individually.  In  regard  to  the  50-Mc.  band,  there  appears 
to  be  substantial  expression  of  approval  of  provision  for 
Technician  Class  operator  privileges  therein. 

3.  As  evidenced  by  the  comment  received,  there  appears 
to  be  considerable  controversy  as  to  whether  technicians 


should  be  allowed  to  operate  in  the  144  Mc.  band.  Because 
of  the  opposition  expressed  by  the  American  Radio  Relay 
League,  and  because  it  does  not  find  the  arguments  ex- 
pressed in  the  comments  otherwise  decisive,  the  Commis- 
sion is  hereby  dismissing  that  portion  of  the  proposed 
amendment  having  to  do  with  technician  privileges  in  the 
144  Mc.  amateur  frequency  band. 

4.  This  amendment  is  issued  pursuant  to  authority 
contained  in  Sections  4(i)  and  303(f),  (g),  and  (r)  of  the 
Communications  Act  of  1934,  as  amended.  IT  IS  OR- 
DERED, That  effective  3:00  a.m.,  EST,  April  12,  1955, 
Section  12.23(d)  of  Part  12,  Rules  Governing  Amateur

appeared  in  QST  during  1954,  and  awarded  the 
authors  cash  prizes  of  $300,  S200  and  $100. 
Single-sideband,  as  might  be  e.xpected  from  its 
rapid  development  in  1954,  was  the  subject  for 
the  No.  1  spot  —  the  judges  were  unanimous  in 
making  the  first  award  to  Warren  B.  Bruene, 
W0TTK,  for  his  November  article,  "Distortion 
in  Single-Sideband  Linear  Amplifiers."  A  special, 
and  hitherto  untreated,  phase  of  TVI  ran  a  close 
second  —  the  next  award  was  to  F.  E.  Ladd, 
W2IDZ,  for  his  two-part  article  in  June  and  July, 


On  March  19th,  200  VEs  representing  all  of  Canada  met  in  Montreal  to  honor  Canadian  Director  Alex  Raid, 
V  E2BE,  who  on  December  31,  1954,  became  the  first  director  to  complete  2.5  years  of  continuous  service  on  the 
ARRL  Board  of  Directors.  Amateurs  from  all  parts  of  Canada  joined  to  present  Alex  with  a  single-sideband  exciter 
unit  and  accessory  gear,  as  a  token  of  appreciation.  Here  (/.  to  r.)  are:  ARRL  General  Manager  Budlong,  WIBUD; 
Mrs.  Gordon  Lynn;  Director  Reid;  Mrs.  Raid;  ARRL  President  Dosland,  \^  0TSN. 


"50  Mc.  TVI  —  Its  Causes  and  Cures."  Anten- 
nas, as  last  year,  provided  the  third  subject  — 
the  award  going  to  William  B.  Wrigley,  W4UCW, 
for  his  February  article  "Impedance  Character- 
istics of  Harmonic  Antennas." 

CHAMBERS'  25TH 

On  March  6th,  C.  Vernon  Chambers,  QST 
Technical  Assistant,  became  the  seventh  member 
of  the  present  ARRL  Hq.  staff  to  reach  the  25- 
year  mark. 

"Vern"  came  to  Hq.  as  an  office  boy,  but  the 
inevitable  happened  —  the  bug  bit,  and  he 
shortly  became  WIJEQ.  His  interest  and  devel- 
oping ability  made  him  a  logical  candidate  for 


W  IJEO 

lab  work,  and  he  turned  out  a  number  of  pieces 
of  gear  for  QST,  v\ath  special  attention  to  low- 
power  equipment  for  the  beginner.  He  was  asso- 
ciated with  Ross  Hull  in  the  development  of 
u.h.f.  gear  for  the  Handbook  and  carried  that  work 
to  completion  after  Hull's  untimely  death.  Vern 
then  took  over  the  ARRL  Technical  Informa- 
tion Service  until  World  War  II  interrupted  with 
both  Army  and  civilian  service  in  the  field  of 
guided  missiles. 

Chambers'  postwar  projects  for  both  QST  and 
the  Handbook  have  included  a  goodly  number 
of  items  at  beginner  level,  but  have  ranged  into 
many  other  fields  as  well  —  mobile  gear,  devel- 
opment of  high-power  r.f.  chokes,  and  all  sorts  of 
general  transmitting  designs.  His  bandswitching 
rig  in  January  195-4  QST  brought  more  response 
from  amateurs  than  perhaps  anj-  other  article 
postwar. 

^^^len  we  use  on  Vern  the  old  saw,  "The 
second  25  years  are  the  hardest,"  it  isn't  really 
funny:  he  has  that  much  longer  to  go  before 
reaching  retirement  age! 

OPERATION  IN  GREENLAND 

For  some  months  negotiations  have  been  in 
process  for  the  authorization  of  amateur  opera- 
tion in  Greenland  by  U.  S.  citizens.  Permission 
has  now  been  granted,  under  an  agreement  with 
the  Danish  government,  and  the  U.  S.  military 


is  to  issue  detailed  rules  and  regulations  as  well 
as  issue  call  signs  from  the  block  KGIAA 
through  KGILZ. 

NOVICE  TALKING  BOOK 

The  Division  for  the  Blind,  Librarj'  of  Con- 
gress, through  the  facilities  of  the  American 
Foundation  for  the  Blind,  has  produced  a  new 
Talking  Book,  "The  Radio  Amateur's  Novice 
Examination,  Questions  and  Answers."  Ex- 
cerpted from  ARRL  publications,  and  with  code 
practice  material  especially  written  and  taped  by 
Hq.,  the  package  consists  of  eight  12-inch  record 
sides.  It  is  available  to  qualified  blind  readers 
through  the  28  regional  libraries  in  the  usual 
manner  (see  list  page  30,  January  1953  QST). 
Thomas  B.  Hedges,  W3QQS,  assistant  chief  of 
the  Division,  contemplates  expanding  the  Talk- 
ing Book  program  to  higher  grades  of  amateur 
license  if  interest  warrants. 


A.R.R.L.  QSL  BUREAU 

The  function  of  the  ARRL  QSL  Bureau  system 
is  to  facilitate  deliver}'  to  amateurs  in  the  L^nited 
States,  its  possessions,  and  Canada  of  those  QSL 
cards  which  arrive  from  amateur  stations  in  other 
parts  of  the  world.  All  yon  have  to  do  is  send  your 
QSL  manager  (see  list  below)  a  stamped  self- 
addressed  envelope  about  4^^  by  9^2  inches  in 
size,  with  your  name  and  address  in  the  usual 
place  on  the  front  of  the  envelope  and  your  call 
printed  in  capital  letters  in  the  upper  left-hand 
corner.  (Bold-face  tvpe  indicates  change  since  last 
QST  listing.)

21st  ARRL  Sweepstakes  Results 


Partl—C.W. 
BY  PHIL  SIMMONS,  WIZDP 


SAYS  W5VNW:  "Thanks  for  40  hours  of  solid 
enjoyment.  As  the  operator  of  a  fixed,  low- 
power  station,  the  Sweepstakes  is  my  choice 
of  all  the  contests."  Says  WIUTA:  "I  hke  the  SS 
because  it  offers  good  practice  in  operating  pro- 
cedure, the  thrill  of  raising  new  sections,  an  op- 
portunity to  learn  how  the  rig  really  performs, 
but  best  of  all,  the  chance  to  study  the  per- 
sonality of  a  good  cross-section  of  Hamdom.  I 
have  observed  with  a  grin  the  leisurely  fellow 
whose  clock  is  five  minutes  slow,  the  hurry-hurrv 
boy  who  doesn't  wait  for  a  'roger,'  and  the  op- 
erator who  CQs  15  times  before  you  find  you've 
already  worked  him."  Says  W0BUR:  "I  Hke  the 
absence  of  the  cut-throat  dog-eat-dog  competition 
that  marks  some  other  contests."  Says  W4CVM: 
"Conditions  were  about  as  near  perfect  as  I  can 
remember  them.  There  seemed  to  be  more  of  the 
'  old  ham  spirit '  this  year,  and  all  of  the  regulars 
were  on  hand:  W3BES,  W4IA,  W9I0P,  WIFTX, 
W4KFC,  W4CIU  and  many  others."  Says 
W8APC:    "Judging    from    the    serial    numbers 


cfrifp^-.-.^^ 


being  sent  the  second  week  end,  the  entire  popu- 
lation of  the  state  of  Connecticut  will  be  needed 
to  check  the  logs!" 

The  foregoing  colorful  contestimonials  show 
why  1796  entrants  (1394  c.w.)  enjoyed  them- 
selves immensely  (and  why  contest-checker 
WICUT,  ex-W5TQD,  almost  went  back  to 
Texas).   Thoy  indicate,   too,   why  the   1954   SS 


««!!IF^^^ 


Jack  Bryant,  W5TFB,  was  stricken  by  SS-itis  at  an 
early  age.  Now  17,  Jack  already  has  stacked  three  con- 
secutive North  Texas  wins,  was  tenth  high  nationally 
and  top  W5  in  the  '54  doings. 

moves  into  the  record  books  as  the  biggest  ever 
held,  dwarfing  previous  highs  registered  in  1939 
and  1953.  Griping  about  contest  rules  and  poor 
conditions  was  all  but  nonexistent  as  scores 
rocketed  to  adding-machine  proportions  and  84 
hard-working  section  and  Novice  winners  earned 
certificates  for  brasspounding. 

We're  pleased  to  revive  a  popular  prewar  SS 
feature  which  listed,  among  other  items,  the 
equipment  and  bands  of  the  section  leaders.  Aided 
by  some  fast  slip-stick  fumbling,  one  finds  that 
there  is  real  thought-food  here;  e.g.: 

1)  About  85  per  cent  of  the  72  section  winners 
utilized  the  trusted  20-40-80- meter  band  com- 
bination (although  five  of  them  scooped  up  extra 
credits  on  15  meters). 

2)  Seventy-seven  per  cent  fell  in  the  100-watts- 
or-less  category,  while  the  rest  ran  high  power. 

3)  The  average  winner  racked  up  590  contacts 
in  66.6  sections  for  97,450  points,  was  active  35 
hours  with  175  watts  input. 

4)  Low-power  champ  was  25-watt  Oklahoman 
W5WZV. 

5)  One-band  champ  was  South  Texan  W5WQN 
with  704  QSOs  on  7  Mc. 

The  set-ups  in  the  tabulation  typify  the  "new 
look"  in  SS  circles,  as  comj^ared  with  the  May, 
1940  QST  version,  which  recorded  such  l)ottles  as 


Md.-Dol.-D.C.  leader  WSJTK  settled  for  180,.S4(» 
points,  ranked  iifth  amonjist  the  1.394  c.w.  entrants 
with  a  100  per  rent  home-hrew  rig.  The  gadget  at  the 
upper  right,  a  photoelertric-keyed  (^Q  SS  wheel,  gave 
a  good  account  of  itself,  Jack  reports. 


QST  for 


860s,  T-40s,  HK-254S  and  211s  in  vogue  in  those 
days.  (And  you  just  can't  hardly  get  them  no 
more!)  Riifle  through  your  old-time  QSTs  and 
see  for  yourself  what  the  previous  generation  of 
SS  enthusiasts  worked  with. 

Now  here's  a  foursome  that  knows  the  business 


by  heart!  Each  sends  code  reminiscent  of  a 
WlAW  Qualifying  Run  and  sports  a  clean,  ether- 
wrenching  signal.  Each  salted  away  over  1100 
contacts  and  attained,  for  the  first  time  in  SS 
annals,  a  final  score  in  excess  of  200,000  points. 
Congratulations  are  in  order,  then,  to  W4KVX

Section-hunting  remains  the  favorite  pastime 
of  a  goodly  share  of  the  gang,  and  it's  quite  an 
art.  Here  is  the  sharp-eared  crew  that  bagged  all 
73  ARRL  sections  in  '54:  Wis  EOB  JTD  ZDP, 
W2FEB,  K2BZT,  W3s  ADZ  ALB  BP:S  CTJ 
FRY  JBC  JNQ  JTC  KT,  W4s  KVX  YFA, 
W5TFB,  W6s  BIP  EPZ  HOC  MUR  PYH  ULS 
UTV  YK,  A'^s  BLL  CEF,  W7s  GEB  KEY 
KVU  PQE,  WSs  DUS  EV,  W9s  10  P  RQM 
YFV,  W0TKX.  Note  that  all  U.  S.  licensing  areas 
made  the  grade.  Saskatchewan,  Yukon/N.W.T. 
and  Idaho  would  seem  to  be  the  toughies;  17  of 
the  37  experts  named  one  of  the  three  as  the  last 
section  snagged.  But  K2BZT,  who  made  the 
"clean  sweep"  in  just  257  contacts,  and  ex- 
WlAW  op  WIJTD,  who  did  it  in  310,  are  the  two 
who  worked  the  tnostest  with  the  leastest.  Choosy 
W0QDF  likewise  merits  honorable  mention  for 
getting  72  out  of  a  mere  74  QSOs. 

Heartening  indeed  are  the  many  friendly  new 
faces  that  crop  up  j'early  in  the  special  Novice 
competition  which  the  Sweepstakes  affords.  When 
three  or  more  KN/WN  people  enter  logs  from  a 
given  section,  the  leader  nabs  an  appropriately- 
endorsed  Novice  certificate.  The  following  year- 
lings earn  a  burst  of  applause,  and  the  certificate 
as  well,  for  graduating  magna  cum  laude  from 
their  first  venture  into  contest  capers:  WNls 
BLD  CDD,  KN2HXR,  WN3ZKH,  WN5HIS. 
KN6EVR,  WX8s  SRK  TGB,  WA'Os  GBC  HAH 
IGV,  \VN0SQE.  See  you  in  the  '55  SS  minus  the 
"N,"  fellows!

Sidelights 

Lavish  antenna  systems  were  broiiglit  into  play  by  the 
200-grand  (luartet.  W4KVX  relied  on  280-  and  40.5-foot 
zepps,  a  7-Mc.  ground  plane,  and  a  14-Mc.  beam;  all  four 
were  suspended  from  or  mounted  on  telephone  poles. 
W9I0P  found  an  end-fed  136-foot  wire,  a  40-meter  ground 
plane,  and  a  20-meter  rotary  to  his  liking;  and  so  did 
W4KFC,  who  utilized  an  identical  bunch  of  skyhooks.  Out 
west,  W7KVU  made  that  huge  signal  even  huger  with  such 
paraphernalia  as  (1)  for  80  meters,  a  wire  12  wavelengths 
long  and  a  half- wave  zepp;  (2)  a  7-Mc.  ground  plane  and 
zepp;  (3)  3-element  wide-spaced  rotaries  for  1.5  and  20.  .  .  . 
Lament  from  multiops  WSs  WIE  WIF  at  close  of  festivities: 
"  Brother,  are  we  tired."  (Boys,  you  weren't  alone!)  .  .  . 
W8CUP  says  his  FL8A  filter  saved  the  day.  .  .  .  W2BRC 
got  43,935  and  W2C.JM  13,069  points  with  attic  antennas. 
.  .  .  W3MUM  pounded  brass  for  the  Order  of  BO  (Boiled 
Owls).   .   .   .  Overheard   on   20   the   last   Sunday:   WIJYH 


Budding  contester  Dick  Brandt,  KN2HXR,  E.  N.  Y. 
Novice  winner,  got  the  most  markers  registered  by  a 
KN/WN  in  SS  competition  —  over  10,000.  For  further 
news  of  Dick's  operating  sojourns,  see  the  Novice 
Round-up  results  on  page  50. 

explaining  the  rules  to  W1KGH/VE8.  After  Rog  had  paved 
the  way,  the  mob  descended.  .  .  .  K2ENO  broke  in  a  new 
SX-24  and  got  7  additional  states.  .  .  .  Anchor  man  for 
Ohio  Valley  Amateur  Radio  Association  was  2-u-att  W8BAE. 
.  .  .  Those  who  swapped  messages  with  lowan  W0NWX 
unwittingly  nailed  FO8AJ/W0.  Bob  was  using  the  trans- 
mitter-inhaler combo  of  the  famous  Clipperton  DXpedition 
(July,  1954,  QST).  .  .  .  W0FVD  is  positive  his  code  speed 
improved  as  a  result  of  struggling  with  weak  sigs  in  the 
QRM.  ...  In  '53  WNIYMA  made  34  QSOs,  in  '51 
WIYMA  got  741!  How's  that  for  improvement!  .  .  . 
W4LVV  found  conditions  good  except  for  one  weird  90- 
minute  spell  on  20  meters  when  it  was  impossible  to  raise 
anyone  although  incoming  signals  were  strong.  .  .  . 
W60AY  is  confident  QSLs  will  come  through  from  several 
new  states  worked.  .  .  .  W3BQU/5  landed  23,490  points 
with  a  24-watt  transformerless  rig.  A  voltage  doubler  juiced 
the  p.p.  117L7s  in  the  crystal  03?illator  circuit.  Dimensions: 
a  pocket-sized  4-by-4  inches.  .  .  .  KV4BK,  ex-7CO  (1912), 
6RX  (1920),  and  W5RX  (1947),  enjoyed  the  "other  side 
of  the  fence  "  despite  fierce  QRM.  QRT  for  20  years,  Charles

QST  for 


returned  to  top  c.w.  form  rapidly  in  the  SS.  .  .  .  Alaskan 
pace-setter  KL7EVR  apologizes  for  his  difficult-to-read  log 
transcribed  at  16,000  feet  during  a  KL7-to-W7  flight.  .  .  . 
A  2-tube  regen  job  performed  the  receiving  chores  for 
W6FAR.  .  .  .  W4KFC'8  1183  stations  worked  in  '53  is 
still  tops.  .  .  .  With  the  same  30-\vatter  he  had  last  year 
as  a  Novice,  W9YOS  was  tickled  to  multiply  his  score  by  3. 
.  .  .  W4KVX  employed  a  card  logging  system  complete 
with  automatic  time  stamp  and  nuinhciing  machine  to 
assist  in  avoiding  or  nullifying  repent  (^."^C  )s  as  tliey  occurred. 
.  .  .  W80TK  thanks  the  boys  for  QHSing  for  him  his  first 
time  out.  .  .  .  W7PQE  got  ten  KL7s  but  had  to  cajole 
VE.5  and  KIlO  non-SSers  into  swapping  |)reambles.  .  .  . 
Complete  break-in  sy.stem  (Marcli,  lO.jl,  QST)  —  using 
tubes  for  antenna-switcliing  and  receiver-(iuieting  —  worked 
great  at  W7GEB.  .  .  .  We  can  tliank  WIRWP  for  in- 
creased Vermont  activity.  Stan  has  been  carrying  on  a 
feverish  one-man  campaign  to  get  better  representation  from 
that  elusive  section.  .  .  .  W4KMF/7  avows  the  competi- 
tion in  Arizona  is  considerably  less  rugged  than  it  was  in 
Virginia.  .  .  .  W.5WZV  cai)tured  his  first  SS  scalp  since 
'way  back  in  '36  and  '37  when  he  earned  Philippine  honors 
as  KAIUS.  .  .  .  WlWAl  snared  his  48th  state,  learned 
much  about  when  to  work  wliich  bands.  .  .  .  W1I.\P  used 
a  receiver-controlled  VFO  on  7  Mc.  .  .  .  WSRQM's  XYL 
presented  him  with  a  new  junior  op  during  the  SS.  .  .  .  The 
last  25-cycle  power  areas  were  being  converted  to  60  cycles 
near  VE3ACB  and  intermittent  power  leaks  held  down  his 
score.  .  .  .  W4KFC  tells  a  little  tale  about  a  newly- 
recruited  Potomac  Valley  member,  W4NQM.  Sparkie  was 
calling  a  Vcrmoiiter  wlien  liis  key  actually  fell  apart,  where- 
upon he  scooped  up  a  screwdriver,  finished  the  call  with  the 
blade,  and  landed  the  Vermont  station!  ..."  My  first  SS 
in  19  years.  The  last  time  I  entered,  as  W2BMX,  I  won  for 
E.N.Y.  witli  two  crystals,  l.")2  contacts.  Needless  to  say,  I 
was  feeling  my  way  in  tliis  one.  .Just  wait  'til  next  year!" 

—  H-'^CA'^l.  .  .  .  "What  a  wonderful  time!  The  SS  seems 
to  get  better  every  year.  Conditions  were  the  best  tliat  I 
can  remember,  and  operating  proficiency  and  signal  (piality 
were  better  than  ever  before.  Cliirps,  yoops  and  dicks  were 
at  a  low  ebb,  making  operating  a  distinct  pleasure.  .  .  . 
Some  sort  of  award  should  be  given  to  the  XYLs  who  are 
the  backbone  of  a  good  score.  Where  would  we  be  without 
the  hot  coffee,  special  meals  at  off-hours,  and  plentiful 
supply  of  sharp  pencils  and  log  sheets.  Yes,  they  deserve  a 
big  lumd  for  their  lielp!" —  \\":KVV.  .  .  .  "Surprised  to 
end  up  with  the  same  mimber  of  contacts  (499)  in  21st  as  in 
20th  SS.  Also  was  lucky  enougli  to  liave  Vermont  and  VE8 
reply  to  my  CQ  machine." —  \V6BII'.  .  .  .  "Wonderful 
contest!  Found  21  Mc.  wide  open  but  nobody  there;  14  Mc. 
best  band  out  here." — \V7GEB.  .  .  .  "  The  20-watt  trans- 
mitter that  gets  RST  599  1000  miles  away  on  3.,")-Me.  SS 
eve,  when  the  customary  handful  of  stations  are  tuning  up 
for  the  event,  is  fairly  ineffective  in  the  melee  starting  at 
1800  EST  the  next  day,  but  75  to  100  watts  does  the  job 
FB.  You  can  get  the  contacts  witli  lower  power  but  you 
have  to  work  hard  and  be  discouragingly  patient.  Every 
year,  though,  I'm  back  with  more  determmation  than  ever." 

—  W8DM.  .  .  .  "First  contest  and  it  was  a  barrel  of  fun." 

—  W8IR0.  ..."  My  object  each  year  has  been  to  work 
all  sections.  Thought  I  had  it  this  time  when  a  VE8  an- 
swered but  discovered  too  late  that  I  had  missed  Sacra- 
mento Valley.  Oh  well,  maybe  neri  year!" —  WSZJM.  .  .  . 
"Wow,  what  a  battle!  Heard  the  W6s  working  WIQMM 
(Vt.)  on  20  but  couldn't  find  him.  My  family  is  beginning 
to  speak  to  me  again!" — W3LMM.  .  .  .  "  Gained  valuable 
operating  experience  and  learned  how  to  tune  up  the  rig 
in  a  hurry." — W0TLD.  .  .  .  "Conditions  excellent  the 
first  session  and  almost  as  good  the  second.  Sections  I  usu- 
ally have  trouble  logging  were  in  abundance,  but  there 
seemed  to  be  a  dearth  of  KZ5,  VE5  and  VE8  participants. 
This    was    my    twelfth    Q^."  —W0YCR.  .  .  .  "Bettered 


With  this  spifTy  layout,  John  Ryan,  W7KVU,  brought 
home  a  blistering  202,210  points  and  the  Montana  wall-

"  My  second  SS  and  pleased  to  better  last  year's  score  con-

VE2CB'.

Twenty-First  Sweepstakes  Contest 

Scores  are  grouped  by  Divisions  and  Sections.  .  .  .  The 
operator  of  the  station  first-listed  in  each  Section  is  award 
winner  for  that  Section  unless  otherwise  indicated.  .  .  . 
Likewise  the  "power  factor"  used  in  computing  points  in 
each  score  is  indicated  by  the  letter  A  or  B.  .  .  .  A  indi- 
cates power  up  to  and  including  100  watts  (multiplier  of 
1.25,  c.w.),  B  over  100  watts  (multiplier  of  1).  .  .  .  The 
total  operating  time  to  the  nearest  hour,  when  given  for 
each  station,  is  the  last  figure  following  the  score.  .  .  .

Two  of  the  tougher  states  to  acquire  while 
working  for  WAS  are  Utah  and  Rhode  Island. 
Not  so  in  the  NR!  On  our  left,  representing 
Rhode  Island,  WNlBIS  supplied  a  multiplier  for 
134,  while  WN7WSS  from  the  Beehive  State 
(Utah)  was  a  choice  one  for  115.  In  the  words  of 
KN6HAN,  "The  contest  brought  out  a  lot  of  the 
rarer  ones!" 

Sideligh  ts 

From  down  Virginia  way,  W4YZC  rei)orts 
some  of  the  best  signals  emanating  from 
WNIACD,  KN2HXR,  WN3ZKN,  KN4ASU/4, 
WN8SWB,  WN9GWS  and  WN9GBC.  From  the 
West  Coast,  San  Joaquin  Valley  leader  KN6HFA 
reports  outstanding  signals  from  WlMX, 
WN0VKI,  KN4ANW,  WN5FJN,  W4VRT  and 
WIWPO. 

Giving  testimony  to  sharp  ears  for  faraway 
sections,  the  following  licensees  racked  up  45  or 
more  of  those  juicy  multipliers.  In  descending 
order  are  eight  star  performers:  WN5FJN, 
W^N0VKI,  WN7YAQ,  WN9GBC,  WN7WSS, 
WN3ZKH,  WN4FR0  and  WNICKA.  Not  only

"After  having  taken  part  in  two  SS  contests, 
I  believe  that  the  NR  is  about  four  times  as  diffi-

in  spite  of  QRM,  QRP,  QSB  and  homework, 
twelve  of  the  boys  came  through  with  150  or

LUCITE  REPLACEMENT  FOR 
WINDOW  GLASS 

A  SHEET  of  3^-infh  lucite,  cut  to  size  and  used  as 
the  replacement  for  a  cellar  windowpane, 
provides  an  easily  worked  surface  for  mounting? 
feed-line  feed-through  insulators,  etc.  Mount 
the  lucite  in  place  with  regular  glazier's  tacks  and 
putty.  Save  the  window  glass  for  the  day  when  it 
becomes  desirable  to  return  it  to  the  frame.

FULL  RANGE  SPEED  CONTROL  FOR 
SEMIAUTOMATIC  KEYS 

A  HIGHLY  successful  method  of  controlling  the 
speed  of  a  bug  or  semiautomatic  key  is 
shown  in  Fig.  1.  With  this  .system,  it  is  po.s.sil)le 
to  slow  down  the  dot  frefjuency  instant anc^ously 
to  any  desired  rate. 

The  drawing  is  more  or  less  .self-explanatory. 
The  only  parts  added  to  the  original  key  are  a 
hairpin-shaped  piece  of  iron  wire  and  one  or  more 
small  cylindrical  .\lnico  magnets  such  as  those  used 
in  speaker  manufacture.  The  hairpin  is  held  in 
place  under  the  thumbscrew  which  normally 
holds  the  sliding  weight  in  position  and  the  mag- 
net or  magnets  hold  themselves  in  the  cradle 
formed  by  the  hairpin. 

The  hairpin  can  be  made  from  a  section  re- 
moved from  an  iron  coat  hanger.  Before  mount- 
ing the  hairpin,  move  the  regular  weight  up  to 


Fig.    I  —  Detail    drawing    of   the    speed-control   for 
hngs  or  semiautomatic  keys. 

the  maximum  speed  position.  When  the  cradle  is 
locked  in  position,  orientate  it  with  the  open  end 
facing  toward  the  rear  of  the  key.  Thus,  by 
merely  removing  the  magnet  or  magnets,  top 
speed  is  available  without  need  for  loosening  any 
screws.  To  come  down  to  a  slower  speed,  put  a 
magnet  or  two  on  the  cradle  (preferable  sizes  are 
thos?  having  a  diameter  measuring  between  ^ 
and  Hi  inches)  and  slide  same  to  the  most 
effective  position.  Even  with  the  heaviest  com- 
bination of  weights  on  my  bug,  and  while  keying 
at  the  rate  of  less  than  six  dots  per  second,  I  can 


get  over  50  cleanly  formed  dots  before  the  bug 
comes  to  rest. 

For  a  few  weeks  after  this  idea  was  first  put  to 
work,  I  had  the  extra  magnets  lying  around  on 
the  desk  where  they  were  easily  misplaced.  When 
I  finally  remembered  the  basic  properties  of  mag- 
nets, I  simpl}-  placed  them  against  the  front 
panel  of  my  receiver  where  the\'  stay  put  until 
wanted.

PROTECTION  OF  TETRODE  SCREEN 
GRIDS 

ONE  of  the  disadvantages  of  using  a  fi.xed 
screen  supply  is  the  excessive  screen  dissi- 
pation that  occurs  when  plate  voltage  is  unin- 
tentionalh'  removed  from  the  tube.  This  draw- 
back of  the  fixed-supply  system  can  be  over- 
come by  feeding  the  screen  through  the  contacts 
of  a  normally  open  s.p.s.t.  relay  as  shown  in 
Fig.  2.  Voltage  for  the  relay  is  obtained  from  the

high-voltage  plate  supply  through  the  dropping 
resistor,  Ri.  The  value  of  resistance  and  the 
wattage  rating  of  /?i  will  be  determined,  using 
Ohm's  Law,  by  the  resistance  of  the  relay  wind- 
ing and  by  the  output  voltage  of  the  h.v.  supply. 
The  most  desirable  feature  of  the  system  is 
that  it  is  automatic.  If  the  plate  voltage  is 
removed  from  the  tube  because  of  a  blown  fuse, 
defective  component  or  the  unintentional  open- 
ing of  a  control  switch,  the  relay  opens  and 
breaks  the  screen  voltage  lead.

[Editor's  Note:  This  circuit  is  quite  similar  to  the  one 
described  by  W0NCV  in  QST  for  December,  19.52.  How- 
ever, in  the  event  of  an  opening  in  the  relay  winding, 
WSMQQ's  arrangement  does  not  affect  operation  of  tlie 
power-supply  bleeder  as  would  be  the  case  with  the  pre- 
viously-described installation.] 

HOMEMADE  RUBBER  STAMPS 

IX  ''Hints  and  Kinks,"  QST,  Xovemljer,  195i, 
there  appeared  a  brief  article  on  homemade 
QSL  cards  printed  with  a  rubber  stamp.  This 
prompts  me  to  call  attention  to  an  article  en- 
titled, ''You  Can  Make  Your  Own  Rubber 
Stamps,"  presented  in  the  September,  1954, 
issue  of  Popular  Science.

PIRATE  G 

44  Hawklmrst  Road 
Coldean,  Brigliton 
Sussex,  England 
Editor,  QST: 

I  am  being  inundated  with  QSL  cards,  mostly  from  W 
hams,  purporting  to  be  confirmation  of  3.5-Mc.  contacts 
(c.w.)  over  the  past  few  months  and  nearly  all  during  the 
hours  0103-0400  GMT.  All  report  high  signal  strength  — 
which  gives  me  an  impression  that  the  station  making  these 
contacts  may  be  on  the  American  continent.  At  any  rate, 
they  are  all  "pirate"  contacts  as  I  do  not  work  3.5  Mc.  and 
?!f !'tr  work  during  the  "little  hours"!   .   .   . 

.  .  .  Their  cards  sent  to  me  reporting  the  "contacts" 
with  my  station  are  being  held  for  evidence  for  the  G.P.O. 
here!  Incidentally,  my  name  is  Cyril  and  nearly  all  the 
cards  sent  address  me  as  Carl  so  I  guess  my  "pirate"  is 
using  that  name  on  the  air.

THIRD-PARTY  TRAFFIC 

MARS/ Amateur  Station  K3WBJ 
Walter  Reed  Army  Med.  Center 
Washington  12,  D.  C. 
Editor,  QST: 

If  one  listens  on  20  meters  he  is  certain  to  hear  Stateside 
stations  handling  traffic  with  the  DL4s,  Gs,  CSs,  Fs  and 
others.  Most  Stateside  amateurs  do  not  realize  that  FCC 
prohibits  third-party  traffic  with  foreign  countries,  except- 
ing Liberia,  Cuba,  Canada,  Chile,  Peru,  Ecuador,  and  those 
stations  operating  beyond  the  continental  U.  S.  A.,  such  as 
KZ,  KP,  KG,  KL,  KA,  etc.,  who  are  licensed  by  FCC. 

The  only  way  traffic  can  be  passed  to  the  U.  S.  A.  from 
Germany  is  on  MARS  frequencies  where  the  German  station 
becomes  a  U.  S.  military  station  using  military  calls  issued 
by  chief  Army  or  Air  Force  MARS,  Pentagon,  Washington, 
D.C. 

It  is  possible  that  the  Stateside  amateur  does  not  know 
this  or  is  too  kind-hearted  to  reply  "Sorry  OM,  but  we  are 
not  supposed  to  handle  traffic  with  DL4  stations." 

To  those  who  are  accepting  'phone-patch  traffic  and  writ- 
ten messages  from  DL4  amateurs,  I  say  let's  do  our  duty  and 
follow  the  rules  of  FCC  —  no  traffic  from  Germany  on  the 
amateur  bands. 

—  Pfc.  Merle  W.  Wynn,  WIDLO 
[Editor's  Note  —  Message  traffic  for  U.  S.  military  per- 
sonnel overseas  is  permitted  only  with  amateur  stations 
identified  by  properly  authorized  call  signs  having  a  one-  or 
two-letter  prefix  beginning  with  W  or  K.] 


NOT  THIS  WAY 

1595  N.  Virginia  St. 
St.  Paul  3,  Mmn. 
Editor,  QST: 

...  In  tuning  across  14  Mc.  I  hear  a  weak  ET3  in 
Ethiopia.  When  he  finishes  his  CQ  I  call  him,  but  he  comes 
back  to  a  Wl.  .\fter  giving  the  Wl  his  report  and  expressing 
delight  in  working  the  Wl  again,  he  turns  it  back  to  the  Wl. 
This  Wl  immediately  opens  the  formalities  with  the  words 
"Say,  I  worked  you  two  months  ago  and  I  still  haven't  got 
your  QSL  —  how  come?  Also,  if  you  run  across  that  ET2  in 
Eritrea,  tell  him  I  haven't  got  his,  either." 

If  I  had  been  tlio  ET3,  I  would  have  tlicre\ipon  turned  off 
the  rig  and  slunk  away,  but  the  P>T3  gamely  comes  back 
and  says,  "Say,  OM,  mail  delivery  in  this  country  is  really 
very  poor  compared  to  the  U.  S.  A.  We  consider  if  we  get  a 
letter  from  your  country  in  two  months  that  that  would  be 


normal  delivery  time.  I  also  been  off  the  air  since  last  work- 
ing you  as  my  837  oscillator  failed  and  I  just  managed  to 
bum  a  substitute  from  a  passing  camel  caravan."  He  then 
turns  it  back  to  Soft-hearted  John,  the  Wl  station,  whose 
first  words  of  sorrow,  condolence,  and  understanding  go  like 
this: 

"Well,  if  mail  delivery  in  your  country  is  so  lousy  as 
to  take  2  months,  you'll  probablj'  be  getting  my  card  any 
day  so  how's  about  mailing  me  your  card  airmail  today?" 
I  never  did  hear  the  ET3  come  back  to  that  bit  of  genius  so 
maybe  even  he  forgot  he  was  a  gentleman. 

To  my  mind  a  suitable  cartoon  to  illustrate  how  bad  this 
QSL  mania  has  become  would  be  one  like  "Gil"  made  up 
years  ago  of  a  big  bandit  with  a  blackjack  in  his  hand 
hovering  over  a  small  cringing  citizen  and  overhead  the 
words  "Gimme  your  handle";  but  in  this  case  substitute  the 
words  "Gimme  your  QSL." 

...  I  wonder  how  many  U.  S.  hams  understand  the  value 
to  a  foreign  ham  of  postage.  Eight  cents  is  plenty  but  even 
to  me  25  cents  for  airmail  is  pretty  strong  between  paydays. 
I  looked  up  the  ET3  and  he  was  listed  as  an  Air  Force  man 
so  I  would  presume  even  he  ate  off  crockery  and  not  gold 
plate.  (Ethiopian  Air  Force  man,  that  is-.) 

Every  time  a  DX  station  calls  CQ,  hordes  of  U.  S.  stations 
call  liim  and  flood  him  with  QSLs.  He  no  doubt  already  has 
hundreds  of  U.  S.  cards,  but  being  a  gentleman,  he  is  obliged 
to  mail  his  in  return  and  postage  can  become  an  important 
item.  Include  return  postage  coupons  to  defray  the  return 
postage  and  to  help  remind  him  to  QSL.  If  he  happens  to  be 
wealthy,  he  can  turn  the  postage  money  over  to  his  favorite 
charity. 

Don't  lose  your  head  if  a  foreign  ham  doesn't  QSL.  Who 
knows  —  maybe  he  is  having  labor  trouble  with  the  fellows 
that  turn  his  tread-mill-powered  generator  like  the  0Q5  in 
the  Belgian  Congo  I  read  of  years  ago.  After  all,  it's  not 
quite  as  bad  as  having  a  doctor  tell  you  that  you  have 
cancer.

'PHONE-BAND  C.W. 

133  Cherry  Ridge  Rd. 
Peoria,  111. 
Editor,  QST: 

I  read  the  letters  sent  in  by  W5UWQ  and  W4UWA 
(March  1955,  p.  46)  and  I  agree  with  both  of  them,  to  a 
certain  extent. 

Contrary  to  what  most  'phone  addicts  seem  to  think, 
c.w.  is  not  "  a  thing  of  the  past " ;  it  plays  just  as  large  a  role 
in  ham  radio  as  'phone  does.  I  will  admit,  however,  that 
some  c.w.  operators  are  inconsiderate  enough  to  work  in  the 
'phone  bands,  and  I  agree  that  these  bands  should  be  set 
aside  for  'phone  only. 

As  for  s.s.b.,  the  letter  from  W8HKE  (right  below  the 
other  two  letters)  hits  the  nail  on  the  head.  I  hope  most  of 
the  anti-s.s.b.  men  read  it  carefully. 

Let's  face  it;  all  three  are  here  to  stay.  Instead  of  arguing 
about  which  one  to  eliminate  we  should  try  to  get  'phone 
and  c.w.  separated,  and  convince  those  d.s.b.  guys  that 
s.s.b.  is  doing  more  good  than  harm. 

—  Bill  Wildfong,  \V9IWC 


58  Tiiroop  Ave. 
Auburn,  New  York 
Editor,  QST: 

In  reply  to  W5L'WQ's  letter  griping  about  c.w.  on  the 

'phone  bands — I  agree  witli  him  completely.  However,  I 

feel  that  something  should  be  done  about  the  overlapping  of 

the  VE  'phone  band  and  the  American  Novice  band  on  80

Sentiments  on  C.  W. 

What  is  c.w.  to  me?  It  is  a  magic  key  that  opens 
many  mysterious  doors  —  an  ethereal  bridge  forged 
of  countless  dits  and  dahs,  borne  aloft  on  the  wings 
of  light,  space,  and  divine  mystery  ...  a  sparkling 
want  that  spans  great  distances  or  hops  V)ackyard 
fences  to  afford  its  disciples  a  brief  glimpse  into  the 
lives  of  others.  ...  It  is  a  lilting  language  which 
commands  either  detached  respect  or  frank  and 
warm  love,  depending  upon  whose  mind  it  touches. 
.  .  .  C.w.  is  a  subtle  bonding  agent  that  deli- 
cately welds  two  strangers  into  an  intimate  oneness 
for  a  fleeting  moment  ...  a  delightful,  tantalizing 
and  yet  thoroughly  satisfying  mistress  to  all  her 
lovers. 

These  thoughtful  words  were  copied  by  OM 
W6KIMJ,  Dan  Peterson,  of  Long  Beach,  during 
a  recent  40-meter  QSO  with  W6()QY,  Betty 
Entner,  of  Coronado.  Dan,  impressed  by  Betty's 
"l^eautiful  bug  fist''  and  devotion  to  c.w.,  shares 
her  sentiments  with  us  with  the  hope  that  they 
may  strike  a  spark  in  the  hearts  of  many  strug- 
gling YL  Novices  and  inspire  them  toward  the 
mastery  of  the  necessary  1)^  w.p.m.  for  their

Armed  Forces  Day  Program  — May  21st 


THE  Army,  Navy  and  Air  Force  invite  all  U.  S. 
amateur  radio  operators  to  participate  in  the 
Armed  Forces  Day  Program  for  1955.  The 
amateur  activities  are  jointly  sponsored  by  the 
Army  Signal  Corps,  Air  Force  Directorate  of 
Communication,  and  the  Naval  Communications 
Division. 

A  receiving  contest  will  be  open  to  anyone  who 
can  copy  International  Morse  Code  at  25  w.p.m. 
Listeners  who  submit  a  perfect  copy  of  the  trans- 
mission will  receive  a  Certificate  of  Merit,  attest- 
ing to  their  code-copying  proficiency,  from  the 
Secretary  of  Defense. 

A  military-to-amateur  transmitting  and  re- 
ceiving test  will  be  conducted  for  all  holders  of 
valid  U.  S.  amateur  radio  licenses.  Headquarters 
stations  of  the  Army,  Navy  and  Air  Force  will 
establish  radio  contact  with  amateur  stations 
and  will  acknowledge  these  contacts  with  special 
QSL  cards.  Each  service  headquarters  station 
will  QSL  separately  so  amateurs  will  have  an 
opportunity  to  qualify  for  three  different  QSLs. 

In  addition,  a  radioteletype  transmission  will 
be  sent  from  MARS  Headquarters  and  from 
official  Navy  stations.  Any  amateur  station  capa- 
ble of  receiving  radioteletype  transmissions  is

'Jf^iSim^ 


THE  best  50-Mc.  season  in  years  could  be 
about  to  begin.  Interest  in  the  band,  lagging 
for  some  time,  shows  every  sign  of  coming 
back  strong.  How  well  it  comes  back  will  depend 
on  how  well  we  respond  to  the  opportunity  that 
is  inherent  in  the  opening  of  the  band  to  Techni- 
cian Licensees,  effective  April  12th.  Conditions 
are  almost  sure  to  be  better  than  for  several 
years,  and  for  the  first  time  we  have  a  real  incen- 
tive that  will  attract  new  hams.  Now  it's  up  to 
50-Mc.  enthusiasts  the  country  over  to  make 
the  most  of  this  chance  to  sell  th<»  band,  and 
keep  it  sold. 

Why  has  50-Mc.  interest  lagged?  We  have  to 
go  back  to  the  resumption  of  activity  following 
World  War  II  for  all  the  factors.  One  certainly 
was  war-surplus  gear,  or  the  lack  of  it.  Right  at 
the  most  opportune  time  for  the  good  of  the 
2-meter  band,  just  as  we  were  changing  over 
from  112  to  144  Mc,  thousands  of  SCR-522s 
and  other  surplus  gear  for  the  new  band  were 
dumped  on  the  market.  You  could  get  on  2  for 
next  to  nothing,  and  v.h.f.  men  bj'  the  thousands 
snapped  up  the  chance. 

But  the  6-meter  band  enjoyed  no  such  bonanza. 
During  the  first  months  on  the  air,  we  had  to 
make  the  shift  from  56  to  50  Mc,  at  a  time  when 
there  was  no  gear,  surplus  or  new,  for  the  new- 
frequency.  What  we  had  we  made  ourselves,  and 
it  is  a  credit  to  amateur  radio  that  we  managed 
to  show  several  hundred  active  stations  on  50  Mc. 
almost  at  once.  The  6-meter  band  was  intriguing 
territory,  and  it  attracted  ciuite  a  few  operators 
who  were  interested  in  more  than  just  routine 
QSOs,  though  it  was  good  for  that  kind  of 
hamming,  too. 

Then  came  TVI.  First  in  the  New  York  area, 
then  elsewhere  as  new  TV  stations  appeared  on 
Channel  2,  50-Mc.  men  found  the  going  too 
rough  for  many  of  them.  Since  the  lifting  of  the 
TV  allocations  "freeze"  and  the  resultant  open- 


This  antenna  system  could  be  the  means  of  achieving 
the  long-sought  goal  of  144-Mc.  DX  up  the  Pacific 
Coast.  A  30-foot  parabola  mounted  on  a  dolly,  so  that  it 
can  be  rolled  around  on  the  flat  roof,  it  is  erected  on  a 
1200-foot  elevation  directly  above  Hollywood.  The 
lights  of  the  Los  Angeles  area  stretch  out  for  20  miles 
toward  Long  Beach  in  this  night  shot  by  KN6GLG. 
K6EGP  is  seated  at  the  left,  W6COH  climbs  the  frame- 
work on  the  rear  of  the  reflector,  and  K6BXW  is  at  the 
right.  W6MJ,  who  sent  the  picture  in,  says  that  a 
kilowatt  rig  will  be  feeding  the  array  this  spring. 


May  1955 


ing  of  many  new  Channel  2  stations  around  the 
country,  the  number  of  active  50-Mc.  stations 
has  dropped  off  from  its  already  none-too- 
healthy  level. 

TVI  in  Channel  2,  from  50-Mc.  transmitters, 
is  undoubtedly  one  of  the  more  difficult  problems 
hams  have  had  to  face,  but  there  are  redeeming 
factors,  even  here.  Not  the  least  of  these  is  the 
less  avid  interest  in  TV^  on  the  part  of  the  general 
public.  Televiewing  is  more  general  than  ever, 
of  coiu-se,  but  with  more  than  one  channel  avail- 
able in  nearly  all  localities,  interference  in  one 
of  them  is  not  the  life-and-death  matter  it  once 
was.  Remember,  too,  that  it  is  usually  a  receiver 
fault;  if  your  rig  is  "clean"  you  can  stay  on  the 
air.  And  we  are  learning  that  the  Channel  2 
problem  is  not  insurmountable.  W2IDZ  showed 
the  way  in  a  two  part  article  in  June  and  July, 
1954,  QST;  an  effort  that  won  him  second  place 
in  the  "Outstanding  QST  Article  of  the  Year" 
contest  for  1954,  incidentally. 

How  bad  is  the  problem,  anyway?  It's  rough, 
if  you  live  in  a  weak-signal  Channel  2  area,  with 
a  forest  of  TV  antennas  around  you,  but  there 
are  several  tricks  that  can  be  employed  advan- 
tageously, in  addition  to  the  filters  described  by 
W2IDZ.  It's  a  local  problem,  mainly,  so  you  can 
help  things  a  lot  by  using  a  high  antenna,  to 
keep  the  main  radiation  pattern  from  warming 
up  neighboring  TV  arraj-s    Low  power  works 


wonders,  and  fortunately,  operating  on  6  with 
no  more  than  a  few  watts  can  be  real  fun. 

If  you  don't  have  Channel  2  to  worry  about, 
6  is  likely  to  be  one  of  the  most  TVI-free  bands 
we  have.  What  interference  you  do  encounter  is 
easily  cured,  in  almost  all  cases  except  where 
Channel  2  is  involved.  In  many  areas,  the  ex- 
tensive shielding  and  filtering,  now  so  commonly 
practiced  in  low-frequency  circles,  may  be  wholly 
unnecessary.  Thousands  of  U.  S.  hams  could 
operate  around  the  clock  on  50  Mc.  without  the 
slightest  worry  about  TVI.  The  main  thing  is  to 
get  them  to  try  it! 

A  series  of  QST  articles  for  the  50-Mc.  new- 
comer begins  in  this  issue.  Technician  licensees 
in  all  parts  of  the  countrj'  will  be  building  6- 
meter  gear  in  the  coming  months.  One  of  them 
may  be  your  neighbor,  or  a  member  of  your 
radio  club.  Like  any  other  beginner,  he  may 
need  help.  When  he  gets  ready  to  go  on  the  air 
he'll  need  someone  to  talk  to.  It's  some  time 
since  we've  had  an  opportunity  to  develop  new 
activity  on  6.  Let's  not  muff  this  one! 

Here  and  There  on  the  V.H.F.  Bands 

The  best  West  Coast  2-meter  DX  in  several  years  is  re- 
Ijorted  this  month  by  K6CAL,  San  Diego.  Her  ]46..5-Mc. 
signals  were  heard  by  W6SXK/mm  at  a  distance  of  more 
tlian  000  miles  out  in  the  Pacific,  at  2037  PST,  Jan.  28th. 
The  report  was  delayed  until  the  completion  of  a  round  trip 
by  the  Hawaiian  Rancher,  the  ship  on  which  W6SXK  makes 
the  run  to  KH6-land  regularly.  Cliff  has  also  heard  the 
Bay  Area  repeater  station,  K6GWE,  at  distances  of  more 
than  300  miles. 

Such  reports  point  up  the  fact  that  conditions  along  the 
Pacific  Coast  may  be  very  favorable  for  long-distance  v.h.f. 
propagation.  The  K6GWE  antenna  is  a  simple  nondirec- 
tional  affair,  and  the  16-element  beam  at  K6CAL/W6IBS 
was  aimed  at  Los  Angeles  during  the  600-mile  reception,  so 
the  signal  was  heard  off  its  side.  How  long  will  it  be  before 
home  stations  in  San  Diego  or  Los  Angeles  work  into  the 
Bay  Area,  or  farther?  We  feel  that  such  an  event  still  awaits 
only  the  use  of  liigh  power,  big  antennas,  c.w.  techniques, 
and  selective  low-noise  receivers  on  regular  schedules. 

A  likely  prospect  for  such  DX  is  the  set-up  shown  in  the 
adjoining  photograph.  This  30-foot  parabola  should  provide 
the  antenna  gain  (though  we  feel  that  the  dipole  is  in  the 
wrong  position!)  and  the  members  of  the  Two  Meter  and 
Down  Club  who  are  in  back  of  project  say  that  there  will 
be  a  high-powered  rig  feeding  the  big  array  this  spring.  This 
would  seem  to  have  what  it  takes  to  work  K6GWE,  WCAJF, 
or  any  of  the  other  good  set-ups  in  the  Bay  area,  and  it 
shouldn't  stop  there.  With  W6JIP,  W70KV  and  others 
around  Portland  using  high  power,  and  W7LHL  reported 
to  be  nearly  ready  to  go  with  a  kilowatt  rig  in  Seattle,  why 
stop  at  the  Bay  area? 

Its  less  than  1000  miles  from  Los  Angeles  to  Seattle. 
Portland  is  about  850  miles.  San  Diego  to  San  Francisco  is 
less  than  500  miles.  Are  these  impossible  distances  on  144 
Mc.  in  1955?  Having  had  a  good  look  at  the  terrain  along 
these  paths  last  fall,  we  still  feel  that  the  best  possible  eciuij)- 
ment  and  techniques  will  turn  the  trick  within  a  month  of 
the  first  time  they're  tried.  We  hope  that  there  is  provision 
in  that  Hollywood  array  for  going  to  horizontal  polarization, 
and  that  there  will  be  a  keying  jack  in  that  high-powered 
rig! 

An  attractive  prospect  for  2-meter  DX  off  the  Atlantic 
Coast  is  Bermuda.  W3YHI  sends  word  that  VP9BM  is  to 
be  on  2  regularly  with  100  watts,  a  low-noise  converter  and 
a  rhombic  centered  on  Philadelphia.  Address:  M/Sgt.  J.  W. 
Wenglare,  1934  AACS  Sqdn,  APO  856,  Postmaster,  N.  Y. 

Another  buddy  of  W3YHI  (when  they  were  DL4CK  and 
DL4XS  on  144  Mc.)  is  getting  set  to  make  a  name  for  him- 
self on  144  Mc.  in  North  Africa.  .Jo  visited  us  during  the 
winter,  full  of  plans  for  higii  power,  rhombics,  hot  converters 
and  other  2-meter  DX  necessities.  Then  he  was  about  to  hop 
off  for  Casablanca,  and  we're  standing  by  to  hear  from  him

any  day  that  he  is  ready  to  take  on  all  comers  for  a  shot  at 
the  2-meter  DX  record. 

In  the  spring,  the  young  man's  fancy  lightly  turns  to 
thoughts  of  expeditions  to  choice  v.h.f.  locations.  Here  are 
two  trips  that  are  well  along  in  the  planning  stages.  W8.JWV 
and  W8GUZ  have  been  dreaming  this  one  up  all  winter. 
They  will  operate  W8JWV/4  from  the  summit  of  Mt. 
Mitchell,  in  North  Carolina,  the  night  before  and  during 
the  June  V.H.F.  Party,  the  7th,  8th  and  9th.  A  16-element 
array  will  be  used  on  a  75-watt  2-meter  rig  with  an  829B 
final.  Operation  will  start  around  1900  EST,  June  7th. 
Mimeographed  notices  have  already  been  sent  out  to  a 
considerable  mailing  list,  and  final  details  will  be  sent  just 
prior  to  the  Party. 

And  here's  one  to  delight  the  hearts  of  searchers  after 
50-Mc.  WAS.  W2QCY  has  decided  that  something  has  to 
be  done  about  the  lack  of  6-meter  stations  in  certain  Western 
States.  Roy  is  planning  to  load  his  panel  truck  with  6-meter 
gear  and  take  off  for  Nevada,  Utah  and  possibly  other  states 
that  are  keeping  scores  of  50-Mc.  men  from  achieving  WAS. 
This  expedition  will  be  well  equipped  as  to  gear,  antennas

QST  for 


and  emergency  power,  and  operation  is  scheduled  for  the 
height  of  the  DX  season,  in  the  latter  part  of  .June  and  early 
July.  There  should  be  a  batch  of  new  candidates  for  the 
coveted  .50-Mc.  WAS  award  before  W2QCY/7  finishes  his 
rounds.  Right  now,  Roy  is  looking  for  two  stalwart  and 
experienced  6-meter  DX  men  to  accompany  him.  Any 
takers? 

If  you  prefer  picnics  to  expeditions,  here  are  a  couple  of 
talk-eat  |)arties  scheduled  for  the  same  date,  .luly  Slst.  The 
Annual  Turkey  Run  V.H.F.  Picnic,  a  fixture  in  Midwestern 
v.h.f.  circles,  will  be  held,  as  always  at  the  State  Park  of 
that  name,  just  north  of  Terre  Haute,  Ind.  W9ZHL,  Terre 
Haute,  is  the  man  to  see  for  more  information.  And  \V8N0H, 
Grand  Rapids,  Mich.,  tells  us  that  the  v.h.f.  fraternity  of 
Western  Michigan  will  congregate  for  the  same  purposes 
at  Allegan  County  Park  on  the  shores  of  Lake  Michigan, 
also  on  .July  31st. 

W8NOII  also  writes  of  an  interesting  comparison  of  2 
and  75  m  checks  made  with  W9RXS,  Milwaukee,  Wise. 
Tills  path  of  about  120  miles  across  Lake  Michigan  shows 
very  satisfactory  signals  with  100  watts  on  144  Mc.  On  3.9 
Mc,  a  400-watt  rig  has  rough  going,  what  with  skip  effects 
and  heavy  QRM. 

A  17.5-mile  sked  has  been  kept  reliably  on  144  Mc.  by 
W9ZHL  and  W0YRX,  near  St.  Louis,  since  last  October. 
On  only  three  occasions  since  that  time  has  communication 
been  difficult  on  voice,  and  many  other  stations  in  the  St. 
Louis  area  and  Western  Illinois  have  called  in  also. 

Last  month  we  mentioned  the  appearance  of  WIDEO, 
Cape  Elizabeth,  Maine,  on  144  Mc.  Herb  has  been  on  regu- 
larly since,  working  WIOOP,  Needham,  Mass.,  nightly. 
He  is  also  on  50  Mc,  and  is  working  down  into  Connecticut 
on  that  band  also,  though  signals  are  stronger  on  the  higher 
band,  wlien  conditions  are  above  normal.  WIDEO  is  pres- 
ently working  on  144.12  and  .50.7  Mc. 

If  you  were  waiting  for  a  shot  at  Florida,  following  our 
recent  report  that  W5VWU  was  moving  there,  don't  wait 
any  longer.  W5A.JG  writes  that  he  worked  W5VVVLVmobile, 
en  route  back  to  New  Mexico.  Leroy  reports  that  the  tropo- 
spheric  season  began  early  this  year,  in  the  Gulf  States,  with 
W4UUF,  Pensacola,  Fla.,  working  into  Texas  on  the  niglit 
of  March  11th.  The  following  morning  signals  were  excel- 
lent from  W5RCI,  Marks,  and  W.5.ITI,  .Jackson,  Miss.,  so 
W5RCI  and  W5AJG  went  to  220,  for  their  first  contact  on 
that  band.  The  distance  is  about  370  miles.  Wo.A.JG  has 
been  running  daily  skeds  on  144  Mc.  with  W5HXK,  Wa- 
tonga,  Okla.,  230  miles,  for  the  past  three  weeks  without  a 
miss. 

The  220-Mc.  band  is  very  much  alive  in  Swarthmore, 
Ridley  Park,  Springfield  and  other  towns  west  of  Phila- 
delphia, according  to  W3TEE.  Several  stations  are  on 
nightly  between  2100  and  2200,  some  having  been  at  it  for 
several  years.  W3LTGA  holds  the  local  record  with  more 
than  1000  QSOs  on  220,  and  W3KPK  is  not  far  behind.  All 
sorts  of  ecjuipment  is  in  use,  including  simple  modulated 
oscillators  and  dipole  antennas.  Anyone  needing  help  in 
getting  started  may  get  in  touch  with  any  of  the  gang,  the 
more  active  members  being  \V3s  AHL  KPK  RW'H  QMQ 
QZT  TEE  UGA  UKG  YQS. 

The  Philadelphia  area  is  good  round-table  territory.  A 
6-meter  group  has  held  forth  each  Monday  night  for  years, 
and  they  frequently  join  in  a  similar  session  held  in  the 
Washington  area  on  Sunday  mornings.  The  over-the-air 
friendships  thus  formed  were  brought  to  a  more  personal 
status  on  March  20th,  when  a  delegation  consisting  of 
W20RA  and  WSs  CGV  CUB  MXW"  RQT  GGR  and 
W8NRM/3  visited  the  Washington  stations  in  a  body. 
First  stop  was  W30JU,  District  Hts.,  Md.,  where  WSs 
YHI  JES  UJG  WOD  and  W4UMF  joined  the  party.  Next 
they  converged  on  W30TC,  Silver  Spring,  where  Bob 
played  them  some  recordings  to  show  how  their  signals 
sound  at  the  southern  end  of  the  circuit.  The  final  shack 
stop  was  W3KMV,  Chevy  Chase,  where  a  main  attraction 
was  a  5-over-5  array  for  50  Mc,  soon  to  be  described  in  QST. 
The  party  wound  up  with  dinner  at  O'Donnell's  Restaurant. 
A  return  visit  to  the  City  of  Brotherly  Love  is  now  planned. 

More  Philadelphia  area  v.h.f.  activity:  The  York  Road 
Radio  Club  has  about  40  crystals  on  146.25  Mc.  An  informal 
net  is  conducted  each  Sunday  at  0930  on  this  frequency, 
with  the  club  station,  W3RDM,  as  control.  A  club  project 
recently  completed  the  construction  of  14  tunable  convert- 
ers, with  6BQ7  front  ends.  A  companion  transmitter  is  next 
on  the  program.  Chief  engineer  for  this  project  is  W3NKD. 
The  club  is  pushing  for  polarization  standardization,  to  end 


the  confusion  now  prevalent  within  a  100-mile  radius,  and 
they  want  ARRL  to  assist  in  this. 

For  a  long  time  we've  been  pushing  as  hard  as  we  know 
how  for  horizontal  polarization.  Conversion  to  horizontal 
is  well  along  throughout  New  England,  New  York,  and 
Northern  New  Jersej'.  In  view  of  the  improvement  in 
working  range  that  has  resulted,  and  the  excellent  results 
in  working  the  vertically-polarized  mobile  stations  that  have 
shown  cross  polarization  to  be  no  problem  in  that  connec- 
tion, we  feel  that  there  is  little  reason  to  continue  \ertical 
polarization  at  any  home  station.  The  way  to  get  standardi- 
zation on  horizontal  is  simply  to  change  over.  If  any  appre- 
ciable number  do  it,  the  rest  will  follow.

W7VMP  144. Mc.  May-June  Schedule 

Experience  has  shown  again  and  again  that  144-Mc 
signals  can  be  heard  over  paths  of  up  to  500  miles  consist- 
ently, if  optimum  equipment  and  techniques  are  employed 
at  both  ends.  What  lies  in  between,  in  the  way  of  mountains, 
may  have  very  little  to  do  with  it,  except  that  when  the 
mountains  are  at  the  right  point  along  the  path  the  signal 
is  better  than  would  be  the  case  over  flat  terrain. 

Most  of  our  inability  to  work  over  mountains  on  the 
v.h.f.  bands  in  the  past  has  been  the  result  of  insufficient 
power,  ineffective  antennas  or  poor  receivers.  With  these 
factors  taken  care  of,  v.h.f.  men  in  many  locations  that 
once  seemed  "impossible"  are  finding  that  2-meter  DX 
can  be  worked.  The  only  real  problem,  when  equipment  is 
taken  care  of,  is  the  lack  of  stations  to  work. 

We  would  have  once  considered  it  ridiculous  to  try  144 
Mc.  between  Phoenix,  Ariz.,  and  Los  Angeles,  for  instance, 
but  W7VMP  has  done  it  often.  Results  have  also  been 
obtained  on  schedules  with  Albuquercjue,  a  mountainous 
path  of  about  the  same  length  in  the  opposite  direction. 

After  a  rebuilding  operation  on  the  exciter,  in  the  interest 
of  improved  c.w.  stability,  The  Three  Fenwicks  are  ready 
for  more  144-Mc.  DX  schedules.  Here  is  what  W7VMP 
will  be  up  to  in  May  and  June.  All  times  are  in  MST. 
Transmissions  will  be  on  c.w.,  with  1  kilowatt  input.  Fre- 
quency: 144.0165  Mc  Antenna:  32  element  horizontal 
array,  72  feet  up.  2000  —  transmit  east.  2005  —  listen  east. 
2010  —  transmit  northeast.  2015  —  listen  northeast.  2020 
—  transmit  north.  2025  —  listen  north.  Other  skeds  will 
be  made,  and  kept,  upon  request.

TI9MHB 

Or  Why  a  DXer  Leaves  Home 
BY  JOHN  R.  BECK,  *  W6MHB 


OFF  the  west  coast  of  Costa  Rica  lies  fabulous 
Cocos  Island,  subject  of  many  legends  con- 
cerning hidden  pirate  treasure.  While  eaves- 
dropping on  a  QSO  between  KV4AA  and  WGVBY . 
I  learned  that  an  expedition  had  been  organized 
to  journey  to  that  tiny  dot  in  hope  of  finding 
legendary  pirate  loot.  Moreover,  the  adventurers 
needed  someone  to  keep  them  in  touch  with  their 
families  via  amateur  radio.  Being  a  DX-minded 
ham,  this  was  a  wonderful  opportunity  to  set  up 
as  a  rare  DX  station  and  be  part  of  what  promised 
to  be  a  highl}-  exciting  adventure. 

Arrangements  were  made  for  me  to  become  a 
member  of  the  expedition  and  it  looked  as  though 
I  was  all  set.  My  XYL,  Margaret,  said  that  I 
would  kick  myself  for  the  rest  of  my  life  if  I  didn't 
go,  and  mj^  employers  —  the  Navy  Department 
—  in  effect  said  the  same  thing. 

On  January  8th  our  party  sailed  from  Los 
Angeles  for  Costa  Rica  on  the  Isle  of  Capri. 
Operating  as  \V6MHB/mm  on  21  Mc,  prelimi- 
narj-  traffic  handling  was  commenced  along  with  a 
few  conventional  QSOs.  Many  contacts  were 
made  despite  an  S9  noise  level  from  numerous 
generators,  fans,  blowers  and  the  like.  During 
our  voyage,  the  ocean  was  generally  smooth 
except  for  two  storms  that  lasted  five  days  out 
of  the  thirteen  we  were  at  sea.  Nevertheless,  I 
was  unable  to  operate  for  onlj^  one  day;  it 
was  just  too  rough  to  sit  on  my  camp  stool  in 
the  radio  shack.  Also,  I  had  wheel  watches  from 
twelve  to  four  —  both  morning  and  afternoon  — 
causing  operation  to  be  limited  to  the  morning 
hours  during  which  21  Mc.  was  open. 

On  the  second  day  out  of  Los  Angeles,  we  re- 
ceived news  that  Costa  Rica  was  in  a  state  of 
revolution.  Naturally,  there  was  much  worry 
over  this,  both  among  the  expedition  members 
and  stations  worked.  Roy  Colwell,  W6LW,  un- 
dertook to  relay  news  concerning  the  rebellion. 
Broadcast  reception  was  anything  but  dependable. 

We  arrived  at  the  Costa  Rican  port  of  Pun- 

*  1567  Terrace  Road,  Walnut  Creek,  Calif. 


tarenas  on  the  21st  of  January  —  a  very  hot  and 
steamy  spot.  Upon  clearance  with  the  Port  Cap- 
tain, we  took  a  jeep  to  San  Jose,  capital  of 
Costa  Rica,  to  have  our  contract  to  hunt  treasure 
signed  and  seek  permission  for  amateur  operation 
while  on  Cocos.  The  fact  that  our  treasure-hunt- 
ing contract  with  the  Costa  Rican  government 
clearly  stated  that  there  was  to  be  no  radio  com- 
munication, e.xcept  with  government  stations  on 
the  mainland,  definitely  complicated  matters. 
Conferences  wnth  Tommy  Gabbert,  TI2TG/ 
K6INI,  brought  out  information  that  the  Radio 
Club  of  Costa  Rica  was  greatly  interested  in 
having  Cocos  represented  on  the  DX  bands.  He 
said  that  David  L.  Maduro,  TI2DLM,  the  guid- 
ing light  of  that  organization,  would  be  the  man 
to  see  for  assistance  in  securing  government 
approval.  David  was  contacted  and  he  and  I 
made  trips  to  see  the  radio  inspector.  It  was 
agreed  that  if  no  mention  was  made  of  the  pur- 
pose of  the  expedition,  it  might  be  possible  to 
operate  as  TI9MHB.  With  the  signing  of  the 
expedition  contracts  to  hunt  treasure  on  the 
island,  permission  was  granted. 
I  was  really  in  high  spirits! 
We  departed  for  Cocos  with  a  full  crew  and 
all  of  our  equipment.  The  voyage  again  was 
smooth,  and  at  four  on  the  morning  of  February 
7th,  we  dropped  anchor  in  Chatham  Bay.  There 
was  work  aplenty  to  be  done.  Rafts  had  to  be 
constructed  and  camping  gear  and  food  had  to 
be  moved  ashore,  not  to  mention  setting  up 
ham  radio  gear.  Landings  were  difficult  in  the 
surf  and  could  only  be  made  at  low  tide  as  places 
to  beach  the  small  boats  often  became  non- 
existent. Furthermore,  many  jagged  rocks  pro- 
trude from  the  water,  making  the  shore  boat- 
work  dangerous  as  well  as  difficult. 

By  sundown  on  February  9th  all  of  the  radio 
equipment  had  been  unloaded  and  set  up.  The 
generators  were  serviced  and  tested  and  all 
was^ready'^with  the  exception  of  an  antenna 
sj'stem.  A  clear  spot  extending  across  the 
sandy  beach  looked  like  an  ideal  place 
for  installing  a  long-wire.  Don  Wallace, 
W6AM,  had  previously  presented  me  with 


Operating  as  TI9MHB  from  Cocos 
Island,  John  U.  Beck,  W6MHB,  spent 
many  hours  at  his  operating  position 
to  provide  a  large  number  of  stations 
with  a  rare  DX  contact.  Working  l.S 
to  160  meters,  2024  contacts  were  logged 
at  his  remote  location. 


QST  for 


a  good-sized  spool  of  wire  which  was  strung  900 
feet  to  a  tree  trunk  on  the  far  side  of  the  beach. 
Height:  about  ten  feet  above  high  tide! 

The  transmitter  was  tuned  to  7003  kc.  and 
seemed  to  perk.  Two  receivers  were  in  operation, 
one  to  monitor  my  own  transmissions  and  the 
other  to  Hsten  to  the  frequency  specified  for 
stations  calling. 

To  test  the  long  ears  of  the  DX  fraternity, 
first  transmissions  consisted  of  "DE  TI9- 
MHB,"  sent  once  and  at  intervals.  Nothing  hap- 
pened for  several  minutes.  The  boys  were 
supposed  to  be  waiting  on  pins  and  needles  and 
for  a  time  it  was  thought  that  the  super  long-wire 
was  not  so  super  after  all.  Finally  WlDDF 
answered;  then  he  of  the  calloused  ears,  KV4AA. 
While  a  five-minute  QSO  with  Dick  was  in 
progress,  the  bojs  caught  on  and  the  pile-ups 
were  beginning  to  form. 

Our  camp's  location  was  excellent  for  working 
the  United  States  and  Europe.  Since  most  of  the 
island  terrain  is  very  steep,  the  only  direction 
in  the  clear  e.xtended  from  approximately  the 
Rock>-  Mountains  eastward  to  North  Africa.  The 
effect  of  the  hills  was  borne  out  bj'  the  fact  that 
all  Pacific  island  signals  were  quite  weak.  EL2X 
was  worked,  but  his  fine  signal  was  all  but  in- 
audible most  of  the  time. 

The  reports  received  while  using  the  long-wire 
were  not  too  favorable.  To  correct  the  situation, 
a  ground  ])lane  for  40  meters  was  put  up  on  the 
beach  area  when  the  tide  was  low.  Rocks  weigh- 
ing up  to  one  hundred  pounds  were  piled  to  a 
height  of  six  feet  around  the  base  of  the  sup- 
l^orting  poles.  The  ground  wires  were  tied  to  some 
of  the  larger  rocks  surrounding  it,  but  the  first 
time  the  waves  roared  in  they  were  scattered 
over  the  surrounding  area.  However,  the  antenna 
i-emained  erect  and  it  was  left  that  way  for  the 
entire  period  of  operation.  Later  an  antenna  of 
the  same  type  was  put  up  for  14  Mc.  When  the 
tide  was  in,  water  came  to  within  eight  inches 
of  the  bottom  of  the  radiator  and  the  ground 
planes  were  submerged. 

Fifteen  meters  was  good  while  it  was  "in." 
Calling  stations  apparently  did  not  hear  each 
other  too  well  as  there  was  quite  a  bit  of  calling 
out  of  turn.  For  'phone  operation,  it  proved  to 
l)e  the  best  band  because  of  the  lack  of  commercial 
QRM  and  the  amount  of  space  available. 

Twenty,  of  course,  was  the  stand-by  in  the 
daytime.  Usual  conditions  prevailed  except  that 
W6s  required  openings  for  loud  signals.  These 
occurred  in  the  early  morning  and  just  before 
the  band  closed  for  Ws  in  the  late  afternoon.  Dur- 
ing the  openings,  W6  signals  were  tremendous

and  eciualcd  those  from  other  districts.  Normally, 
most  stations  heard  from  W7-land  eastward 
were  S9  during  the  entire  daylight  period. 

Operation  on  14  Mc.  'phone  was  slow  because 
of  the  large  number  of  strong  stations  calling 
simultaneously.  Nevertheless,  many  contacts 
were  made  in  spite  of  the  QRM. 

For  the  first  few  evenings  Forty  was  very  good 
but  when  the  pile-ups  got  down  to  the  weaker 
stations  commercial  interference  became  trou- 
blesome. 

Eighty  provided  a  big  surprise.  It  seemed  to 
be  the  best  band  for  all-around  contacts  and 
many  stations  reported  our  signals  strongest  on 
that  band.  It  was  found  that  the  long-wire  did 
not  function  too  well  on  Eighty.  Something  better 
had  to  be  erected.  Two  trees,  one  in  our  camp, 
were  found  situated  about  150  feet  apart.  A  bow 
and  arrow,  used  by  one  of  the  expedition  members 
for  hunting,  was  used  to  get  a  piece  of  light  twine 
over  one  of  the  trees.  The  twine  was  fastened  to 
an  insulator  at  one  end  of  a  3.5-Mc.  doublet  and 
then  raised.  One  of  the  Costa  Rican  boys  climbed, 
"Tarzan  style,"  up  the  vines  that  hung  from  the 
other  tree  and  secured  the  far  end.  This  new 
antenna  was  forty  feet  high  and  seemed  to  per- 
form very  effectivelj\ 


May  1955 


Many  European  contacts  were  made  on  all 
bands  and  I  was  greatly  surprised  at  the  solid 
signals  that  were  booming  in  from  that  part  of 
the  world.  Many  U.S.S.R.  stations  were  heard 
working  each  other.  In  fact,  several  times  during 
our  schedules  with  WGLW,  these  stations  were 
much  louder  than  Roy. 

A  few  contac^ts  were  als(j  made  on  75  'plionc, 
but  broadcast  harmonics  from  the  Mainland 
proved  troublesome  on  that  band. 

I  had  promised  several  of  the  IGO-meter  gang 
that  I  would  make  an  attempt  to  operate  on  the 
"top."  So  the  old  long- wire  was  loaded  up  and 
several  CQs  were  sent.  Just  about  the  time  it  was 
thought  that  IGO  was  for  the  birds,  W0NWX,  "ye 
olde  Clippertonian,"  heard  my  peanut  whistle 
and  the  first  160-meter  QSO  with  Cocos  was  in 
the  books.  Twenty-one  contacts  on  that  band 
followed.  Subsequent  reports  from  England 
indicated  that  TI9MHB  was  heard  in  Europe  by 
at  least  one  listener.  The  morning  after  the  169- 
meter  operation,  seaweed  was  hanging  from  the 
long- wire.  How  the  thing  worked  is  beyond  me! 

An  attempt  was  made  to  improve  the  contact 
format  used  by  previous  expedition  and  contest 
ops.  One  gimmick  was  to  end  a  transmission  with 
the  call  of  the  station  being  worked,   the  idea 


The  -.liDic  .11  (.li.itluiin  Ha>  is  littered  with  rocks. 
The  larger  <>iie>  are  carNed  with  the  names  of  ships 
and  seafarers  who  have  visited  Cocos.  Some  inscrip- 
tions date  back  over  100  years;  almost  to  the  time 
pirates  were  active  in  the  area.  The  expedition  also 
left  its  share  of  autographs. 

Chief  inhabitants  of  Co<-os  arc  hermit  crabs,  wild 
pigs,  deer,  antl  small  lizards;  there  are  also  many 
tro[)ical  birds.  Fishing  is  excellent  but  sharks  up  to  six 
feet  in  length  infest  the  waters  surrounding  the  island. 

I{ising  above  the  rocks  on  the  shore  of  Chatham 
Bay  stands  the  ground  plane  antenna  used  by  TI91VIUB 
for  40-meter  operation.  'J'he  antenna  remained  erect 
despite  merciless  pounding  by  waves. 


being  that  everj'one  calling  should  know  the 
characteristics  of  my  signal.  Also,  if  there  was 
interference  during  the  first  part  of  my  trans- 
mission, it  might  be  gone  before  the  end.  The  fact 
that  very  few  repeats  were  requested  indicated 
that  the  pracitice  paid  off. 

Another  scheme,  although  not  new,  was  to 
sjx'cify  th(!  calling  frequency.  I  had  my  VFO 
running  at  all  times  so  I  was  unable  to  listen  in 
on  my  own  frequency.  Calls  were  always  re- 
quested to  be  from  ten  to  twenty  kc.  higher. 

On  twenty  'phone,  especially,  the  calling  fre- 
(luency  system  was  abandoned  because  the 
resultiitg  heterodynes  were  so  fierce  that  it  was 
impossible  to  read  anyone.  The  practice  of  not 
specifying  a  listening  frecjuency  and  continu- 
ously tuning  over  the  entire  'phone  band  was  the 
only  logical  solution.  This  jammed  up  the  band 
fairly  effectively  for  everyone  but  seemed  to 
be  the  only  way  that  stations  could  be  copied. 
Some  of  the  sharper  (?)  operators  would  make 
nice  long  calls  after  every  transmission  from  me. 
Naturally,  this  did  nothing  to  alleviate  QRM. 

Several  hundred  messages  were  handled  and 
the  expedition  crew  and  their  families  were  quite 
pleased  with  TIOMHB's  efforts  to  maintain 
efficient  communications  between  them.  The 
DX  gang  stood  by  in  a  most  commendable  man- 
ner during  the  traffic-handling  periods.  All  traffic 
for  the  expedition  was  handled  by  W6DFY, 
WGLW,  W0CO  and  W0ELA. 

Who  provided  the  best  signals?  W4KFC  was 
one  of  the  better  from  the  East  Coast;  even  on 
160  he  peaked  to  S9.  The  Midwest  provided  the 
most  consistently  strong  signals.  W8DUS  was 
always  thundering.  From  the  West  Coast, 
WGYMD  stood  head  and  shoulders  above  all 
others. 

Finally,  on  February  22nd,  the  expedition  had 
completed  its  task.  The  equipment  was  loaded 
aboard  the  Isle  of  Capri  and  we  sailed  for  Pun- 
tarenas  on  the  evening  of  the  same  day.  Upon  my 
return  to  San  Jose,  Ted  Westlake,  TI2BX,  and 
his  wife,  Virginia,  invited  me  to  their  beautiful 
country  home.  It  was  there  that  the  process  of 
returning  flesh  to  my  bones  began  (I  had  lost 
some  fifty  pounds  during  the  expedition). 

Later,  WGLW,  W6TT  and  TI2RU  arranged 
for  me  to  fly  home.  Arriving  at  the  Oakland  air- 
port, I  was  greeted  by  W6DIP,  WGLW,  and 
Margaret,  my  ever-faithful  wife. 

In  conclusion,  thanks  to  all  who  helped  make 
TI9MHB  a  reahty:  The  Northern  California 
DX  Club;  the  Radio  Club  of  Costa  Rica; 
WGTT  and  W6DUB  of  Elmar  Electronics  who 
supplied  a  good  portion  of  the  equipment; 
WGDIP  who  loaned  me  a  receiver  and  a  generator; 
and  W6KEK  who  supplied  another  generator. 

The  TI  hams  are  certainly  a  wonderful  group 
and  their  hosi)itality  and  generosity  are  not  easily 
exceeded.  They  treated  our  group  royally  and  we 
are  more  than  grateful  for  their  help  and  con- 
sideration. 

And  so  now  —  the  end  of  a  wonderful  journey. 
Did  I  hear  someone  say,  "Where  next?"  ?

CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD 


How: 

When  (he  hounds  of  spring  are  on  wirtter's  traces 
.  .  .  goes  the  first  stanza  of  the  Wouff  Hong 
Song,  the  hallowed  club  anthem  of  our  beloved 
DXHPDS  (DX  Hoggery  and  Poetry  Deprecia- 
tion Society).  We  swiped  that  from  Swinburne 
because  we  know  he  referred  to  DX  hounds  in 
particular  and  because  we,  too,  congregate  an- 
nually around  this  time.  Yes,  indeed,  a  goodly 
crowd  was  there! 

It  was  put  up  to  Great  Circles  lioot  to  get  tlu? 
show  on  the  road  after  the  first  round  of  <  )ld 
Haywire  began  radiating.  This  he  die!  with  a  lilt- 
ing lament  to  the  late  QHL  file  f)f  one  bright  boy 
who  didn't  believe  in  DXCC's  "DX  insurance": 

"Two-fifty  confirmed,"  claimed  O'.Sciuire 
Who  dared  them  to  call  liim  a  liar. 

"Send  in,  men?  Wliat  for? 

I'll  wait  till  I've  more!" 
Voii  jjiiessed  it:  O'Squire  had  a  fire. 

Slickrig  Toppenbottom  followed  C'irclcs  lo  the 
rostrum  with  a  blast  directed  at  s('hizoi)hrenic 
DX  stations  who  advocate  ojx'rating  piocedures 
they  themselves  negate: 

This  rare  one  bleats  out  m  great  heat: 
"Spread  out!  Spread  out  or  I'll  q\ieet!" 

So  we  move  for  the  jerk 

And  who  does  he  work? 
The  lid  wlio  remains  zero-beat. 

Then  Owlbait  Ostrowski  limned  in  rhyme  the 
impressive  ingeimitx'  of  100,000  McScree,  a  bird 
who  tallies  his  DX  score  in  terms  of  kilocountries: 

"The  rules  are  all  wrong! "  cried  McScree 

Whose  Slobovian  card  was  n.g. 
So  he  made  his  own  list 
And  there's  nothing  he  missed  — 

All  stations  are  countries,  you  see. 

The  next  ration  of  ridicule,  delivered  by 
Feeders  N.  Twining,  was  dedicated  to  that  small 
pack  of  watt-mad  megacyclic  megalomaniacs  who 
erroneously  visualize  themselves  as  ham-band 
Voices  of  America: 

When  Two-Gallon  Mossbrain  dropped  dead 
We  found  nary  a  tear  being  shed. 

For  Hamdom,  no  loss  — 

Such  input  made  Mo.ss 
Just  a  bootleg  commercial,  instead. 

W6MUR,  the  sole  out-of-towner  to  brave  the 
vicissitudes  of  this  year's  DXHPDS  powwow, 
then  rose  to  the  occasion  with  a  tongue-in-cheek 
salute  to  all  purveyors  of  scuttlebut  DXpedi- 
tionary  sensationalisms : 

One  rare  catch  popped  up  "in  Albania," 
And  another  "in  West  Transylvania"; 
The  grapevine  went  mad 
But  the  outcome  was  sad  .  .  .

You'll  have  to  finish  that  last  one  yourselves, 
gang,  for  Bill's  punch  line  was  drowned  out  by 
commotion  in  the  rear  of  the  hall.  A  flying  squad 
of  our  sworn  adversaries  from  the  Euphemistic 
Order  of  DXpurgators  barged  in  and  broke  up 
our  gathering  with  tear  gas,  cherry  bombs,  and  a 
shower  of  leaflets  labeled,  "It's  Only  a  Hobby, 
Fellows." 

What: 

And  rvhal  a  hobby!  (They  laughed  and  laughed  when  little 
Elmer  said  he  was  going  up  into  his  attic  to  chat  with  the 
I'.  S.  Undersecretary  of  State  and  the  King  of  Nepal.  They 
didn't  know  that  Elmer  was  a  ham.)  But  that  is  neither  here 
nor  there.  Before  we  tackle  our  monthly  "How's"  Band- 
wagon we  should  remind  you  that 

In  the  ten  to  follow,  frequencies  (given  in  number  of  kc.  above  the 
lower  band-limit)  appear  in  parentheses,  times  irithovt.  E.g.,  (9)  = 
14.009  kc.,  if  the  paragraph  deals  irith  20-meter  work.  Times  are 
GMT,  using  the  nearest  whole-hour  figure  such  as  7  for  0720  or 
omo,  0  for  OOIB  or  2349.  As  a  rule  each  UX  call  is  mentioned  but 
once  per  band.

surprising  lack  of  W5  W6  and  \V7  signals  during  the  ARRL

Oceania  —  No  U.  S.  amateur  yet  has  collected  the

American  DXers  are  invited  to  apply  ._._._  The  scarcity 
of  VK2s  in  the  1955  ARRL  DX  Test  was  caused  by  serious 
New  South  Wales  flood  conditions,  the  worst  in  recent  years. 
Most  VK2s  on  the  air  at  that  time  were  QRL  pushing 
emergency  traffic  on  WIA's  emergency  nets.  VK2WI  was

Full  Addresses  and  Proper  Check  Required 
on  Originations.  Ever  find  yourself  on  the 
deliver}'  end  and  unable  to  do  the  job?  All 
amateurs  (and  MARS  originators  too)  are  asked 
not  to  permit  amateur  traffic  to  start  on  its  way 
bj'  radio  unless  it  can  carry  an  adequate  address 
to  insure  delivery.  Each  handling  station  should 
have  an  understanding  about  the  check  or  word 
count  before  receipting  (QSL)  for  the  message! 
The  newcomer  is  urged  to  study  all  the  concise 
information  in  the  League's  booklet  Operating 
an  Amateur  Radio  Station  relating  to  checking, 
servicing  and  handling  messages.  It's  part  of  the 
tradition  of  amateurs  that  they  actually  can 
communicate,  and  in  a  responsible  manner.  Both 
old  and  new  timers  may  benefit  by  rereading 
W3ECP's  "Net  Know-How"  in  March  QST. 

But  let's  hear  from  Cy  Read,  W9AA,  who 
takes  up  this  matter  with  Hq. :  "I  am  still  run- 
ning a  full  head  of  steam  about  the  way  messages 
are  coming  through.  Some  addresses  are  'strictly 
from  hunger.'  In  this  case  there  was  no  one 
nearer,  and  the  NCS  asked  me  to  mail  it.  In  due 
time  it  came  back  marked  'unknown'  whereupon 
I  sent  out  a  SVC.  ...  It  appeared  that  many 
of  the  traffic  stations  located  in  small  towns  or 
at  great  distances  don't  seem  to  realize  that  any 
message  going  into  a  big  city  must  have  a 
complete  and  accurate  address,  if  it  is  to  get 
through.  Get  the  boys  to  understand  and  insist 
on  a  proper  address  on  every  message  originated, 
and  our  service  will  be  improved.  Note  the 
check  on  the  original  message  doesn't  agree 
with  the  text  count.  .  .  ." 

The  example  Cy  attached  was  a  MARS 
origination  (Hawaii).  The  principle  of  needing 
more  address  applies  to  many  a  U.  S.  A.  amateur 
radiogram.  Refile  procedure  is  given  in  detail, 
page  130,  June  '53  QST.  All  amateurs  should 
refuse  to  start  messages  unless  they  are  complete 
and  in  standard  ARRL  form  for  amateur  circuits. 
There  are  more  amateur  nets  functioning  effec- 
tively to  get  traffic  through  than  ever  before. 
Make  texts  concise,  address  complete,  with  a 
'phone  number  where  feasible,  and  operators 
should  check  them  carefully  as  to  destination. 
Haphazard  and  rubber-stamp  originations  gen- 
erally impair  more  than  they  advance  the 
amateur  traffic  reputation! 

How  to  Improve  Your  "Fist."  Sending  at 
home  on  a  code  practice  oscillator  or  buzzer  in 
step  with  tape-sent  transmissions  is  a  good  way 
that  some  are  overlooking  to  improve  one's 
sending.  You  can  note  from  page  70  in  this

teurs concede  it  is  much  easier  to  copy  at  high 
speed  than  it  is  to  send  manually  and  well  even 
at  moderate  speeds.  Interspersed  periods  of 
sending  practice  are  worth  while,  since  they  buck 
up  the  ability  on  the  receiving  side  too. 

Smoothness  in  sending  requires  good  spacing 
and  rhythm.  Newcomers:  to  avoid  having  your 
sending  fall  into  the  category  where  TEST 
becomes  "NST"  and  CQ  becomes  "NNQ"  bear 
in  mind  that  by  copying  tape  (automatic) 
transmissions  regularly  with  some  time  spent 
sending  in  step  with  the  tape,  such  defects  can 
be  overcome.  Code  then  becomes  most  enjoyable 
and  effective  for  two-way  communications. 

Country  Considerations.  What  makes  a  coun- 
try in  the  ARRL  Countries  List?  Not  many 
DXers  think  much  about  this  since  the  standard 
list  for  reference  is  reprinted  up-to-date  in  each 
January  QST,  and  put  out  in  folder  form.  You 
can  mark  your  countries  as  you  work  them, 
while  collecting  your  100  cards  to  submit  for 
DXCC.  Watch  DXCC  Notes  headings  in  QST 
for  any  possible  list  changes;  such  are  usually 
additions.  "How's  DX?"  may  give  you  additional 
facts  about  the  presence  or  absence  of  signals 
or  countries,  also  "where  to  find"  the  DX 
reported,  documenting  your  kind  assistance. 
The  ARRL  Countries  List  is  a  yardstick  for 
DX,  the  standard  for  use  in  connection  with 
the  ARRL  DX  Competition  and  the  DX  Cen- 
tury Club.  But  we  started  to  tell  you  what's 
behind  the  list  in  terms  of  country  policy. 

The  League  Communications  Department  is 
assigned  the  honor  and  responsibility  for  making 
operator  certifications  and  awards.  A  standard 
published  list  assures  uniformity,  and  one  goal 
for  all  concerned  to  work  toward,  either  con- 
testwise  or  for  countries  credits.  A  group  of 
experienced  staff-member  licensed  amateurs  as- 
sist the  Communications  Manager  in  arriving  at 
decisions  through  discussion  and  analysis  of 
operating  problems  requiring  administrative  re- 
view. On  countries  the  "approach  to  the  prob- 
lem" may,  we  think,  interest  you. 

There  are  three  criteria  on  which  facts  are 
determined  in  approaching  any  countries  prob- 
lem: (1)  Does  the  area  have  political  inde- 
pendence? (2)  Does  it  have  adequate  geographical 
separation  from  a  parent  nation?  (3)  Does  it 
have  foreign  lands  in  between?  Of  course,  what- 
ever the  list  permits,  it  is  the  same  for  all  working 
to  the  goal.  But  the  reason  respect  for  our  list 
is  general  is,  we  think,  because  it  is  progressively 
kept  up  to  date  as  governments  change;  also  that

The  ARRL  Countries  List  is  the  guide  in

FIELD  DAY  STATISTICS 

By  Roy  T.  Harmon,  W0IUB 

Field  Day  is  the  most  important  event  of  the  year  in 
amateur  radio.  It  started  in  1933  and  has  continued  to 
the  present  day  (except  for  the  war  years),  and  Field  Day 
records  should  interest  many  hams.  Am.ericans  seem  to 
like  records  as  incentives.  The  four-minute-mile  hope  kept 
track  fans  enthused  for  many  years  even  though  there 
were  no  milers  around  who  could  rome  close  to  it.  Following 
this  line  of  thought,  I  sat  down  with  my  QST  back  issues 
and  figured  out  the  postwar  records  for  Field  Day.  I  used 
numbers  of  contacts  to  determine  winners,  since  multipliers 
and  point  systems  have  changed  from  time  to  time. 

Some  of  the  feats  look  almost  impossible,  while  others 
seem  like  they  could  be  beaten  easily  by  concerted  effort. 
One  fact  that  surprised  me  was  that  so  many  of  the  records 
were  set  in  1949,  1950  and  1951.  One  would  think  that 
since  Field  Day  popularity  has  always  grown  from  year  to 
year,  all  of  the  records  would  have  been  set  in  19.53  and  1954, 
b\it  not  so!  The  W6MBA  mobile  rig  sure  must  be  a  corker, 
and  W3JTK's  outstanding  work  as  single  operator  at 
home  has  stood  unchallenged  since  1949.  And  in  1951 
eighty-seven  ops  participated  at  one  club  set-up;  what  a 
circus  that  must  have  been! 

Here  arc  the  figures.  Hope  the  hams  around  the  country 
enjoy  them.

CODE-PROFICIENCY  PROGRAM 

Twice  each  month  special  transmissions  are  made  to 
enable  you  to  qualify  for  the  ARRL  Code  Proficiency  Cer- 
tificate. The  next  qualifying  run  from  WlAW  will  be  made 
on  May  12th  at  2130  EDST.  Identical  texts  will  be  sent 
simultaneously  by  automatic  transmitters  on  1885,  3555, 
7125,  14,100,  21,010,  52,000  and  145,600  kc.  The  next  quali- 
fying run  from  W60WP  only  will  be  transmitted  on  May

BRIEF 

An  amateur  recently  wrote  the  ARRL  Communications 
Department  as  follows:  "Is  it  possible  to  obtain  a  duplicate 
A-1  Operator  Club  certificate?  Some  time  ago  my  wife 
pitched  mine  in  the  alley  in  a  fit  of  pique.  Now  my  new 
wife  might  like  to  see  how  important  the  old  boy  is!" 
(P.  S. :  He  got  the  certificate.)

QST  for 


shelved  because  there  was  no  hint  as  to  when  the  emergency 
occurred.  The  date  of  a  blizzard,  tornado,  fire  or  other 
memorable  local  occurrence  might  be  well  known  to  you, 
but  chances  are  we  never  heard  about  it  —  so  date  your 
emergencies,  will  ya,  huh? 


Having  just  finished  compiling  some  figures  based  on 
100  EC  anniial  reports  received  CIO  per  cent  of  all  ECs),  we 
thought  you  miglit  be  interested  in  some  of  the  statistics 
and  estimates  derived  therefrom.  We'll  present  these  in 
expository  fashion,  so  you  won't  have  to  try  to  interpret 
from  tables. 

First  of  all,  let  us  note  the  percentage  of  EC  annual 
reports  received  —  10  per  cent.  Not  too  good,  is  it?  Yes,  we 
know  that  being  an  EC  has  a  lot  of  work  connected  with 
it.  and  to  a  person  not  too  fond  of  paper  work  (and  whc  is?) 
it  seems  as  though  Headquarters  or  the  SEC  or  someone 
is  constantly  badgering  ECs  for  reports.  Actually,  all  we 
ask  is  a  Form  5  (post-card  size)  once  a  month  to  the  SEC 
and  a  one-page  group  of  figures  once  a  year.  From  these, 
we  can  glean  some  well-educated  national  estimates,  since 
100  per  cent  response  is  unthinkable. 

You  see.  we  use  these  data;  we're  not  just  trying  to  make 
you  work  for  nothing.  Once  each  month  we  summarize 
SEC  reports  (which  are  based  on  your  monthly  Form  5 
reports  tc  the  SEC),  and  once  each  year  we  summarize 
EC  annual  reports  and  make  estimates  of  national  totals 
based  on  this.  Naturally,  the  larger  the  percentage  of 
reports  received,  the  more  accurate  cur  estimates  will  be. 
However,  based  on  the  10  per  cent  received  this  year, 
here's  about  what  the  .AREC  looks  like  nationally. 

We  have  about  40,000  AREC  members,  of  which  75 
per  cent  are  full  members.  Almost  1.'5!.000  of  these  are 
"signed  up  in  RACES,"  by  which  they  probably  mean 
they  are  enrolled  in  local,  regional  or  state  civil  defense 
communications  with  R.\CES  in  mind,  whether  or  not 
they  are  RACES-authorized.  There  are  about  780  e.xisting 
RACES  plans  within  the  AREC  structure,  not  all  approved 
by  FCDA  and  FCC  as  yet.  Most  AREC  members  continue 
to  operate  on  the  28-Mc.  band  (over  20,000),  but  3.5-Mc. 
C.W.,  3.8-Mc.  'phone  and  7  Mc.  also  have  strong  foUowings 
—  and  of  course  most  of  them  operate  regularly  on  more 
than  one  band.  Six  and  two  meters  have  shown  great 
increase  in  popularity,  however. 

The  AREC  has  an  estimated  17,000  mobile  units  in 
operation.  Ten  meters  is  still  the  most  popular  band  for 
mobile  emergency  communication,  followed  by  80  75 
meters,  2  meters  and  "other"  bands,  in  that  order.  How- 
ever, since  the  1953  year  end,  the  greatest  percentage 
increase  in  mobile  emergency  operation  has  been  on  two 
meters.  The  increase  on  ten  meters  has  been  slight. 

Nearly  all  estimates  are  up  from  last  year,  an  indication 
that  amateur  interest  in  emergency  work  is  still  on  the 
increase,  probably  a  result  of  the  impact  of  civil  defense. 
Our  estimates  show  a  decline  in  the  number  of  fixed  stations 
having  emergency  power  available,  and  declines  in  the  niun- 
ber  of  AREC  members  using  80  c.w.,  75  'phone  and  two 
meters  (although  mobile  operation  on  2  shows  a  large 
increase). 

Interesting?  We  thought  so,  and  encouraging,  too.  How 
accurate  are  these  estimates?  Just  exactly  as  accurate  as  a 
10  per  cent  response  in  reporting  will  allow. 

Fellows,  how  about  putting  dates  on  the  emergencies, 
drills  and  tests  you  tell  us  about?  We  had  reports  on  four 
different  emergencies  lined  up  this  month  that  had  to  be

W5ZU  calls  our  attention  to  an  emergency  operation 
which  occurred  last  year  that  never  got  written  up,  except 
in  his  SCM  column.  We  think  it  should  be  recorded  in  this 
column.  It  seems  that  last  Octoljer  6th,  7th,  8th  they  had 
quite  a  flood  in  the  Roswell-Dexter-Hagerman-Artesia- 
Carlsbad  region  of  New  Mexico  when  seven  inches  of  rain- 
fall within  48  hours  sent  the  Hondo  and  Pecos  Rivers  on  a 
rampage.  Roswell  amateurs  M'os  BZA  BZB  QKG  TBP 
WPA  YFN  YUM  YWU  ZM  ZU  gathered  on  3838  kc. 
while  mobiles  TT'.5s  BZA  BZB  WPA  YUM  visited  the 
flood  area  and  relayed  reports.  Once  the  situation  was 
"cased,"  a  few  stations  stayed  on  hand  all  night  while 
the  rest  got  some  sleep.  During  the  night,  W5WPA  partici- 
pated in  the  rescue  of  a  truck  and  workers  at  the  Hondo 
Dam,  west  of  Roswell.  At  0830  on  the  7th,  W5ZU  fired  up 
as  control  station  with  Was  ARD  CXC  EFT  PSP  UTS 
QKA  RNG  YAS  ZGG  AHQ  FAB  PGJ  RZS  TDB  UP  in 
the  net,  in  addition  to  those  on  the  previous  night.  Emer- 
gency work  conducted  included:  U)  Assistance  to  Southern 
Union  Gas  Company  in  coordinating  work  on  an  eight-inch 
gas  main  crossing  the  Felix  River  north  of  Hagerman 
(mobiles  Was  CXC  BZA  BZB  WPA,  and  fixed  stations 
ir.5s  .\I\  YAS  PSP).  (2)  An  emergency  call  for  boats  to  be 
furnished  by  the  National  Guard  was  coordinated  by  W5s 
BZA  CXC  and  AK,  and  later  rescue  of  a  man  on  an  over- 
turned boat  was  coordinated  by  Wos  AK  ARD  CXC.  (3) 
Communications  for  radio  station  KSVP,  which  had  to 
leave  the  air;  CAA  was  notified  that  tower  lights  were  off 
(W5PSP  and  W5ZU).  (4)  Reports  on  flood  conditions  were 
relayed  up  and  down  the  valley.  (5)  W5UP  stood  by  at 
National  Guard  Headquarters  in  Roswell  to  link  units  in 
Dexter  and  Hagerman  areas.  (6)  W5BZA  BZB  mobile 
encountered  extremely  high  water  between  Dexter  and 
Roswell;  as  a  result,  the  road  was  closed  to  traffic.  (7) 
Railroad  tracks  were  washed  out  near  Dexter,  W5BZB 
reporting  same  to  the  Santa  Fe  Railroad  office.  (8)  Because 
of  the  loss  of  life  and  number  of  missing  persons,  many 
welfare  messages  were  handled  in  the  3838-kc.  network.

On  January  14th,  an  Air  Force  C-45  ran  out  of  fuel  20 
miles  northwest  of  Austin,  Texas.  Upon  hearing  the  engines 
quit  as  the  plane  passed  overhead,  W5YYM  contacted 
W5TFY  in  Austin  and  set  the  Austin  Emergency  Net  in 
operation  on  29.2  Mc.  A  few  'phone  calls  indicated  the 
authorities  knew  the  plane  was  do\\Ti,  but  had  no  idea 
where.  W5YYM  soon  located  the  airplane  on  a  ranch  about

a  mile  from  the  nearest  road.  Doctors  and  ambulances 
were  ordered  and  the  CAA,  Texas  Department  of  Public 
Safety  and  Sheriff's  department  were  notified.  Mobiles 
W5s  KNM  PRO  QZJ  left  immediately  for  Lake  Travis 
to  aid  in  the  search  for  a  crew  member  who  bailed  out  and 
was  mi-ssing.  For  the  first  30  minutes  YYM/m  was  the 
sole  means  of  commvmications  between  the  scene  of  the 
crasli  and  the  state  police  and  other  authorities.  Much 
traffic  was  handled  concerning  directions  to  the  scene  of 
the  crash,  medical  aid,  etc.  The  missing  crewman  was  found 
by  a  ranch  hand  so  all  mobile  units  excei)t  YYM  returned 
to  Austin  by  2030.  The  net  closed  down  at  211.5.  Mot)ile 
units  participating  were  W.5s  FXN  EHD  QZ.J  PRO.  W5TFY 
was  NCS.  —  ]V5TFY. 

Amateurs  in  Paterson,  N.  J.,  assisted  police  in  solving 
some  mysterious  crimes  during  1954.  EC  W2ESW  was 
contacted  by  the  civil  defense  director,  at  the  request  of 
police,  and  21  amateurs  set  up  a  net  on  two  meters,  with  a

Each  car  was  assigned  a  "beat"  in  the  neighborhood  where 
the  assailant  was  known  to  be  operating.  The  patrol  started 
at  0100  and  continued  until  0.530.  This  continued  for  four 
months,  but  no  further  attacks  were  made.  However,  on 
Octolier  14th  at  0347  one  of  the  cars  (W2Z0E  with 
KN2JCR)  reported  a  suspicious  character  on  one  of  the 
streets  in  the  area,  and  he  was  i)icked  up  by  police.  His 
retention  resulted  in  eventual  arrest  and  the  solving  of  a 
number  of  previously-unsolved  robberies.  This  continuing 
patrol  in  cooperation  with  Paterson  police  was  conducted 
by  the  following  amateurs:  Wl2s  ESW  GQD  ZOE  NEZ

laboratad  in  assisting  search  operations  for  a  crashed  jet 
plane  on  January  13th.  Search  was  conducted  from  1900 
to  0500  the  next  day  using  the  10  meter  c.d.  frequency,  but 
distances  proved  too  great  and  the  search  was  reorganized 
using  75  meters.  Here  the  situation  was  just  the  opposite, 
with  long  skip  making  multiple  relays  necessary.  W6EJU's 
portable  emergency  trailer  was  set  up  as  control  station, 
with  one  relay  viaWOOLG.  W6EJU,  K6ARY  and  K6FCZ 
operated  the  control  station.  Amateurs  were  responsible  for 
finding  the  pilot's  body  and  uno;)ened  pirachute,  first 
reports  of  this  coming  from  W6PIQ.  W6W,JF  says  that 
training  in  traffic  handling  showed  up  clearly  in  all  ojicra- 
tions.  Other  amateurs  reported  to  have  particijjated  in 
this  emergency  include  K6s  HWB  DBH  GZZ  AJN  BNS  and 
WGGRO. 

Reportwise,  we  started  the  new  year  with  a  bang,  as 
17   SECs  submitted  monthly  reports,   representing  3878 


AREC  members.  This  beats  January  of  1954  and  1953  both 
in  reports  and  coverage,  and  also  ties  January  of  1953 
in  reports,  so  we're  off  to  a  flying  start.  Let's  keep  those 
reports  coming  in!  Initial  reporting  sections:  Minn.,  Wash., 
Maritime,  Tenn.,  W.  N.  Y.,  W.  Fla.,  N.  Y.  C.-L.  L,  Ga., 
Ky.,  E.  Fla.,  Ala.,  East  Bay,  San  Joaquin  Valley,  La.,

how  about  you  other  56  SECs? 

RACES  News 

A  good  many  RACES  organizers  have  written  us  for 
"the  latest  dope  on  RACES,"  or  information  on  how  to 
organize  RACES.  These  are  pretty  general  requests,  and 
they  usually  get  pretty  general  answers.  Just  in  case  you 
are  contemplating  asking  us  the  same  sort  of  questions, 
here  are  some  answers: 

1)  There  is  a  brief  boildown  on  how  to  organize  RACES 
in  our  booklet  "Emergency  Communications,"  distributed 
free  of  charge  to  all  AREC  members.  If  you'd  like  a  copy, 
just  ask  for  it. 

2)  The  complete  RACES  regulations  are  included  in 
any  recent  edition  of  The  Radio  Amateur's  License  Manual, 
available  from  ARRL  for  fifty  cents.  Or.  if  you're  interested 
only  in  the  RACES  regulations,  your  best  bet  is  to  write 
to  the  Superintendent  of  Documents,  Government  Printing 
Office,  Washington,  and  ask  for  Part  12,  FCC  Regulations, 
Rules  Governing  the  Amateur  Service.  It'll  cost  you  twenty 
cents  a  copy. 

3)  Three  articles  on  the  subject  of  RACES  were  written 
in  1953,  and  most  of  the  information  therein  still  applies. 
In  any  event,  it's  good  background.  Read  "The  Radio 
Amateur  Civil  Emergency  Service"  in  three  parts,  in 
March,  April  and  May  1953  QST.  Other  articles  on  RACES 
have  appeared  in  1953  QSTs  for  Jan.,  Feb.,  July,  Sept., 
and  1954  QSTs  for  Feb.,  Apr.,  July,  Aug.,  Sept.,  Nov.,  and 
Dec. 

4)  If  you  have  any  specific  questions  or  problems,  write 
and  tell  us  about  them.  We'll  try  to  help  you. 


FCDA  now  will  approve  for  matching  funds  civil  defense 
equipment  installed  in  private  cars  provided  title  remains 
with  the  state  or  political  subdivision.  So  if  you've  been 
held  up  in  getting  that  mobile  rig  installed  for  civil  defense 
because  you  think  you  can't  get  matching  funds  for  installa- 
tion in  private  cars,  now  you  can  go  to  it.  Reference  is 
FCDA  Memorandum  COMM-2. 


Speaking  of  matching  funds,  there  still  seems  to  be 
some  confusion  regarding  the  term  "FCDA  approval"  as 
it  applies  to  RACES  equipment.  Such  approval  has  to  do 
otily  with  matching  funds,  and  admittedly  the  FCDA 
sjjecs  are  high.  If  your  civil  defense  people  want  to  pay  the 
whole  price  (and  this  is  invariably  considerably  less  than 
you  wovdd  have  to  pay  for  gear  that  does  meet  FCDA 
specs),  any  type  of  amateur  equipment  is  permissible, 
provided  it  complies  with  FCC  regulations. 

What's  new  in  your  RACES  outfit?  Got  any  hot  ideas 
you'd  like  to  share  with  the  rest  of  the  amateur  world? 
How  about  gimmicks  for  recruiting,  training,  getting  results 
in  drills,  building  gear,  etc.?  Come  on,  you  RACES  en- 
thusiasts, give!

TRAFFIC  TOPICS 

Someone  reminded  us  tliat  we  have  never  printed  a 
picture  of  our  BPL  Traffic  Medallion,  authorized  by  the 
Board  of  Directors  at  its  1954  meetinj;.  Most  of  you  traffic 
men  (and  gals)  who  have  been  working  so  hard  to  get 
this  award  don't  even  know  what  it  looks  like.  So  here  it  is, 
about  twice  actual  size.  Purty,  ain't  it? 


February  reports: 


How  do  you  get  it?  Well,  it's  easy  —  all  you  have  to  do  is 
to  make  BPL  three  times  since  .June  I,  19ol.  After  your 
third  BPL  is  printed  in  Q^T,  we  send  you  a  little  card 
that  says  you  handled  all  that  traffic  by  yourself,  at  your 
own  station,  on  amateur  freciuencies,  in  standard  ARRL 
form.  You  sign  this  card,  send  it  back  to  us,  and  we  send 
you  the  medallion. 

You  only  get  one  medallion,  so  take  care  of  it.  We're 
not  going  to  send  you  one  for  each  three  times  you  make 
the  BPL.  Wear  it  on  your  watch  chain,  or  as  a  necklace 
ornament,  and  wear  it  proudly  at  club  meetings,  conven- 
tions, or  other  amateur  gatherings.  It's  a  luark  of  distinc- 
tion, like  a  Phi  Beta  Kappa  key. 

Miscellaneous  net  reports:  (1)  The  Early  Bird  Net  traffic 
count  for  February  was  782.  (2)  The  Transcontinental  Relay 
Net  had  28  sessions,  tralTic  total  of  1230,  participation  by 
seven  stations.  (3)  The  North  Te.\as-Oklahoma  Section 
Net  had  28  sessions,  i>23  check-ins,  333  messages  handled. 
(4)  The  First  Call  Area  of  the  Transcontinental  'Phone 
Net  registered  674  m<'SsaKe  counts  with  14  stations  par 
ticipating.  (5)  The  College  Net  met  8  times,  was  attendcl 
by  56  different  stations,  handled  13  messages. 


National  Traffic  System.  We  have  .just  comi)leted  compila- 
tion of  some  NTS  19.54  statistics,  which  might  be  of  interest. 
NTS  nets  reported  9642  sessions  in  1951,  handled  106,904 
messages.  We  received  285  reports  altogether,  about  half 
of  them  reports  of  section  nets,  the  rest  regional  and 
area.  About  25  per  cent  of  the  reported  NTS  traffic  total 
for  the  year  was  reported  by  section  nets.  Kudos  to  the 
managers  of  IRN,  4RN,  8RN,  EAN  and  CAN  for  a  100 
per  cent  reporting  job  during  1954.  RN6,  9RN,  TEN,  TRN 
and  PAN  also  rejjorted  every  month,  but  data  on  the 
report  were  incomplete  or  not  properly  executed  through 
misunderstanding.  This  makes  ten  of  the  14  NTS  nets  at 
regional  and  area  level  turning  in  reports  every  month 
during  1954.  A  very  wonderful  reporting  record,  gang.  We 
dream  of  1955  and  a  perfect  record.  Yes,  we  said  "dream." 

The  Tenth  Regional  Net  handled  by  far  the  greatest 
amount  of  traffic  (21,972)  during  the  year,  with  9RN 
second  with  less  than  half  as  much  (7822).  Much  of  this 
traffic,  in  both  cases,  was  "throvigh"  traffic  not  ordinarily 
handled  at  regional  level,  although  9RN  returned  to  a 
strictly  regional  function  with  its  separation  from  TLJ  in 
April.  Among  the  remaining  regional  nets,  RN6  was  high 
with  4501,  followed  closely  by  RN5  with  3874  and  4RN 
with  3765.  The  three  area  nets  were  very  close,  with  PAN 
tops  at  9506,  followed  by  EAN  with  8109  and  CAN  at 
7715. 

All  in  all,  a  very  good  NTS  year,  showing  a  continued 
increase  in  interest  and  activity.  Of  course  we  can't  show 
an  increase  forever,  but  we  think  still  mere  progress  can 
be  made  before  we  reach  a  peak.  Let  each  NTS  net  endeavor 
to  do  its  share  to  account  for  an  even  better  showing  in 
the  year  1955.

At  the  time  this  copy  was  being  written,  reports  were 
missing  from  3RN,  RN6,  9RN,  TEN  and  two  TCC  direc- 
tors—  just  after  we  got  through  bragging  above  about 
the  reporting  record  for  1954.  No  doubt  some  of  them 
will  be  coming  through  late,  and  whether  or  not  we  can 
get  them  into  the  coijy  remains  to  be  seen.  NCSs  can  help 
their  net  managers  to  report  on  time  by  reporting  their 
session  figures  to  him  promptly.  Depend  on  your  report 
not  making  (jST  unless  received  here  by  the  fifteenth  of 
the  month,  even  though  we  can  sometimes  squeeze  it  in 
late;  because  sometimes  we  can't.

'iSTENiNG  on  almost  any  amateur  band  one  is  likely  to  get  the  impres- 
sion that  a  new  type  of  r.f.  amplifying  system  has  recently  been  developed. 
This  "new"  system  eliminates  all  T.V.I. ,  all  spurious  and  harmonic  radia- 
tions, has  high  efficiency,  has  low  efficiency,  uses  only  special  tubes,  can 
use  any  tubes,  etc.,  etc.  Thus,  it  is  evident  that  some  degree  of  confusion 
exists  and  it  seems  appropriate  to  again  review  some  of  the  clear-cut  facts 
about  linear  amplifiers. 


^ 

^^H 


'hey  are  not  new  at  radio  frequencies  as  they  have  been  used  for  years 
by  commercial  services.  .'\11  amplifiers  have  some  degree  of  distortion  thus 
developing  harmonics  and  inter-modulaticjn  products.  A  linear  by  its  na- 
ture will  have  less  of  these  unwanted  products,  but  good  operating  and 
engineering  practice  make  mandatory  a  carefully  designed,  tuned  tank 
circuit  or  pi-network  output  to  reduce  spurious  radiations  to  a  minimum 
level. 


^. 


'he  efficiency  of  a  linear  amplifier  is  lower  than  a  Class  C  stage  when 
rated  on  a  plate  power  input  basis,  but  when  used  for  S.S.B.  and  properly 
rated  and  measured  can  provide  about  65*^^  [,  plate  efficiency. 

O^LMOST  any  tubes  can  be  used  as  linear  amplifiers.  Some,  however, 
will  have  higher  internal  losses  than  others,  but  would  also  exhibit  these 
same  characteristics  when  used  in  Class  C  applications. 

CyV  convenient  measure  for  evaluating  linear  amplifiers  on  a  cost  basis, 
for  a  given  plate  input,  is  to  compare  the  coml^ined  replacement  cost  of 
the  r.f.  and  rectifier  tubes.  For  500  watts  input  and  Class  B  operation  the 
most  economical  combination  is  a  pair  of  811-A's  and  866-A's  for  a  total 
cost  of  slightly  more  than  $14.00.  The  associated  circuit  simplicity  for  this 
combination  also  assures  increased  reliability  and  further  economies.  The 
dollars  thus  conserved  can  be  spent  for  the  most  efficient  r.f.  input  and  out- 
put ciicuits  to  reduce  drive  requirements  and  obtain  the  maximum  sup- 
pression of  spurious  signals. 


c/i/L 


'LL  of  these  features,  and  more,  are  in  the  new  HT-31  amplifier  soon 
to  be  announced.

"IITTIE  MAC"

.3.W-i*-*, 


Ideal  trimmer 
for  VHF  range 

To  keep  pace  with  the  continuing  efforts  of 
the  electronic  industry  toward  miniaturiza- 
tion of  components,  Hammarlund  has  intro- 
duced a  tiny  variable  capacitor,  type  "MAC". 
This  component  provides  the  low  minimum 
capacity  essential  for  use  as  a  trimmer  in 
the  VHF  range. 

The  silicone-treated  base  is  only  3^  x  % 
inches.  Its  rotor  and  stator  are  soldered  as- 
semblies of  brass,  nickel-plated  for  low  losses, 
while  the  wiper  rotor  contact  is  nickel-plated 
beryllium-copper.  Rotor  and  stator  terminals 
are  positioned  to  permit  short  leads. 
A  threaded  bearing  is  provided  with  fiat 
sides  to  permit  single-hole  mounting  without 
turning. 

The  new  units  are  available  to  fulfill  capacity 
requirements  between  1.4  and  19.6  mmf.  Try 
one  in  your  next  piece  of  gear.

Science  Teachet'Ham  says  — 

"My  HQ-140-X  is  the 
best  buy  I  ever  made" 


Fred  J.  Rescorl  is  both  a  science  teacher 
and  a  ham,  and  as  such  can  appreciate 
both  the  practical  and  theoretical  sides 
of  radio.  Fred  has  been  a  satisfied 
Hammarlund  customer  for  years,  using 
Hammarlund  capacitors  and  other  com- 
ponents in  home-built  equipment,  and 
now  has  a  Hammarlund  HQ-140-X  re- 
ceiver in  his  ham  station. 

Fred  is  enthusiastic  about  Hammarlund 
products.  In  his  latest  letter,  he  says,  "My 
HQ-140-X  is  the  best  buy  I  ever  made. 
It's  the  receiver  I  recommend  to  my 
friends.  It  has  performed  the  way  you 
said  it  would  —  outstanding  sensitivity 


and  selectivity,  with  almost  no  frequency 
drift." 

Fred  J.  Rescorl's  happy  experience  with 
Hammarlund  products  is  no  accident. 
Rather,  it  is  the  result  of  careful  engineer- 
ing exemplified  in  the  professional  char- 
acteristics of  the  HQ-140-X.

Here  it  is!  The  new,  improved  Viking  "Ranger" 
with  the  perfect  keying  system.  No  more 
clicks  and  chirps  even  when  driving  a  full 
kilowatt!  Timed  sequence  keying  provides 
ideal  "make"  and  "break"  on  your  keyed 
signal,  yet  VFO  is  keyed  for  fast  break-in. 
Press  the  key  and  the  VFO  turns  on  quickly 
(before  the  keyed  amplifier),  and  it  stays 
on  a  fraction  of  a  second  after  the  amplifier 
cuts  off.  Wave  shaping  is  then  applied  to 
the  keyed  amplifier  stages  for  a  perfect 
waveform.  Time  delay  sequence  is  adjust- 
able and  may  be  set  to  operate  so  fast  that 
a  "breaking"  signal  can  be  heard  between 
transmitted  dots!  Entirely  electronic  in  oper- 
ation, the  system  utilizes  a  type  of  grid 
block  keying  without  relays  and  provides 
clean  and  crisp  electronic  keying. 

Buy  your  Viking  "Ranger"  today!  Truly 
the  finest  low  power  rig  available,  it  packs 
enough  power  for  enjoyable  contacts  all 
over  the  world.  Later  using  the  "Ranger"  as

Power  Amplifier  and  enjoy  the  ultimate  in 
high  power  performance  and  convenience.

KENTUCKY  — SCM,  Robert  E.  Fields;  W4SBI — 
NIZ  is  really  carrying  the  ball  for  the  new  (KPN)  Ken- 
tucky 'Phone  Net.  The  first  14  days  of  the  new  Kentucky 
Net  operation  showed  these  figures:  236  stations  called  in, 
an  average  of  16.7  stations  per  net;  32  messages  handled, 
an  average  of  2.28  per  net.  Net  time  is  1 :30  p.m.  CST. 
Mon.  through  Sat.  and  8:00  a.m.  Sun.  The  freciuency  is 
3960  kc.  CDA,  SEC  for  Kentucky,  asks  that  all  Kentucky 
ECs  report  to  him  the  number  of  AREC  members  they 
have  signed  up.  Every  amateur  in  Kentucky  should  register 
station  facilities  and  availability  as  an  operator  with 
AREC.  Registration  forms  may  be  had  by  contacting 
your  EC,  SEC,  or  SCM.  The  Mic-Key  Radio  Club  of 
Russellville  has  a  Novice  Emergency  Net  operating  Sun. 
at  2:00  p.m.  CST  and  Thurs.  at  7:00  p.m.  CST  on  3735  kc.

SCMs:  Joe  Beljan,  8SCW;  Bob  Cooper,  8AQA.  SEC:  GJH. 
With  HKT  retiring  as  our  SCM  I  am  sure  that  you  will  join 
me  in  expressing  our  thanks  to  him  for  a  job  well  done  and 
extend  to  him  best  wishes  for  the  future.  In  taking  over 
the  duties  of  this  office  I  pledge  you  my  very  best  effort 
to  maintain  the  same  calibre  of  service  that  you  are  accus- 
tomed to.  Many  thanks  to  all  who  supported  me  in  the 
election.  There  is  no  misunderstanding  on  my  part  that 
this  is  a  one-man  job.  Rather,  it  is  one  of  coordinating  the 
cooperative  efforts  of  all  members  in  this  section.  Let's  all 
keep  striving  to  keep  the  fine  reputation  that  we  in  Mich- 


igan enjoy.  Examination  of  the  appointments  file  indicates 
a  laxity  on  the  part  of  some  appointees  to  have  their  ap- 
pointment certificates  endorsed.  Please  be  reminded  that 
failure  to  keep  your  appointment  current  is  basis  for  can- 
cellation. It  is  impossible  to  notify  each  appointee  when  to 
apply  for  endorsement  —  it  is  your  responsibility.  Word 
from  our  SEC  regarding  approval  of  the  Michigan  Com- 
munications Plan  is  encouraging.  As  soon  as  it  is  ratified 
by  the  FCC  and  the  FCDA,  our  RACES  Plan  can  blossom 
into  being.  Many  AREC  registrations  are  being  received, 
but  many  more  will  be  needed  to  fill  the  ranks.  GJH  has 
spent  much  time  doing  the  ground  work  so  let's  show  our 
appreciation  by  backing  him  and  the  rest  of  his  AREC 
organization  with  a  solid  membership.  Remember,  fellows, 
in  the  event  of  a  disaster  only  those  qualified  as  RACES 
stations  will  be  allowed  to  help.  Trafllc:  (Feb.)  W8NUL

WNSSVL's  25  watts  gives  the  Cincy  "Big  Boys"  some- 
thing to  worry  about.  According  to  DAE,  the  Sat.  and 
Sun.  1100  BN  sessions  are  bringing  'em  out.  The  Net  has 
procured  1000  message  cards  with  a  pool  of  12  sharing  the

and  the  National  Traffic  System.  LVF  has  returned  to

to  do  the  trick.  With  1000  volts  on  the

are  badly  needed  for  the  area  between  Schenectady  and 
Plattsburg.  also  in  Sullivan  and  Delaware  Counties.  At- 
tention ECs:  If  your  appointment  is  due  or  past  due  for 
endorsement  and  you  wish  to  continue,  it  is  important 
that  you  notify  the  SCM  within  the  next  thirty  days. 
Failure  to  do  so  will  result  in  immediate  cancellation.

Further  discussion  of  the 
"Robert  Dollar"  Oscillator 

Lost  month  we  discussed  use  of  the  circuit  shown  in  Fig. 
1  for  overtone  use;  and,  as  redrawn  in  Fig.  2,  as  a  basic 
Pierce  Oscillofor.  (OST,  April,  1955). 

Now,  if  capacitor  C  (Fig.  2)  is  tuned  to  opproach  the 
third  overtone  resonant  frequency,  a  point  will  be  reach- 
ed where  the  crystal  ceases  to  oscillate  on  its  funda- 
mental and  begins  to  oscillate  on  its  overtone  fre- 
quency. At  this  point  a  change  In  the  oscillator  fre- 
quency occurs,  since  the  overtone  frequency  is  not  an 
even  multiple  of  the  fundamental.  An  increase  In  grid 
current  and  output  on  the  third  harmonic  will  be  noted 
as  caplcator  C  is  tuned.  This  some  circuit  may  be  used 
on  even  harmonics,  however  the  crystal  continues  to 
oscillate  on  Its  fundamental  in  this  case.  Thus  it  can 
be  seen  that  the  "Robert  Dollar"  circuit  will  oscillate 
under  a  wide  variety  of  conditions  and  if  the  tuned 
circuit  L-C  is  not  properly  adjusted,  overtone  operotlon 
will  not  be  realized. 

With  plated  overtone  crystals  the  circuit  shown  in  Fig.  3 
provides  equal  or  more  output  under  similar  conditions 
than  does  the  circuit  in  Fig.  1.  In  this  circuit  the  crystol 
will  operate  only  on  its  overtone  frequency  and  depends 
on  the  tuning  of  L-C.

MALLORY  HAM  BULLETIN 


Newj  compact 
Vibrapacks® 
to  power 
your  mobile 
rigs . . . 


Before  vou  start  working  over  your  battery- 
powered  gear  for  the  outdoor  radio  activity 
that  will  soou  be  in  full  swing,  stop  in  and  see 
your  Mallory  distributor.  He  is  prepared  to 
introduce  you  to  a  new  Mallory  Vibrapack 
vibrator  power  supply  that  you  can  fit  into 
almost  any  type  of  mobile  equipment. 

So  small  that  it  fits  into  the  palm  of  vour  hand, 
this  new  power  supply  puts  out  plenty  of 
wattage.  It  embodies  design  principles  that 
Mallory  engineers  have  learned  in  25  years' 
experience  in  building  vibrator  operated  power 
supplies  for  communications  equipment.  Youll 
find  that  our  designers  have  used  techniques 
formerly  reserved  exclusively  for  commercial 
mobile  equipment. 

Here  are  some  highlights.  The  same  communi- 
cation-duty, series  drive  vibrator  found  in 
taxi,  police  and  utility  two-way  transmitters 
and  receivers  is  used.  High  stability  ceramic 
capacitors  are  used  in  critical  parts  of  the 
circuit.  Heavy  gauge  steel  protective  cover  and 
bottom  plate  snap  on  and  off  in  an  instant,  to 
make  replacement  of  vibrator  and  rectifier  tube 
a  few  seconds'  work  even  on  field  location. 
When  you  remove  the  bottom  plate,  all  wiring 


P.  R.  MALLORY  &  CO.  Inc. 

P.  O.  Box  1558 
INDIANAPOLIS  6       INDIANA 


is  exposed  and  accessible  for  trouble-shooting. 

Special  attention  has  been  given  to  hash  filter- 
ing in  the  "A"  and  "B"  power  leads.  A  separate 
external  connection  to  the  rectifier  heater  saves 
your  battery  during  standby,  and  provides 
instant  return  to  operation. 

The  Vibrapack  has  been  designed  to  let  you 
provide  whatever  low  frequency  filtering  is 
necessary  for  your  particular  equipment  .  .  . 
without  paying  for  parts  and  wiring  that  you 
may  not  need.  You  can  connect  the  output 
"as  is"  to  a  transmitter  or  receiver  that  already 
has  its  ow  n  filter  system.  Or.  if  you  w  ant  to  add 
a  filter  to  the  Vibrapack,  the  chassis  has  been 
pimched  and  space  allowed  for  the  installation 
of  a  Mallory  multi-section  FP  electrolytic 
capacitor. 

Power  ratings  are  conservative,  to  assure  you 
of  higher  efficiency,  peak  conservation  of  bat- 
tery power  and  long  operation  between  charges. 

Ask  your  Mallory  distributor  to  show  vou  the 
new  Mallory  VP  (6),  (12)  and  (24)  Series 
Vibrapacks,  and  to  give  you  their  electrical 
characteristics.  Or,  just  drop  us  a  letter  and 
we"ll  send  you  complete  details.

Centralab  Ampec® 

3-stage  P.  E.  C* 
Audio  Amplifiers 

You  can  use  them  to  build  all  sorts 
of  exciting,  miniature  projects  — 
pocket  radios,  mike  preamplifiers, 
signal  tracers,  portable  megaphones, 
phonograph  pick-ups,  hearing  aids, 
model  controls — even  stethescopes 

Yes,  sir,  you  can  really  have  a 
"picnic"   with   Ampec.     It's  the 
highest  form  of  Printed  Electronic 
Circuit  and  provides  complete 
electrical  service  from  input  to 
output.  Wiring,  capacitors,  resistor, 
and  tube  sockets  are  bonded  to  a 
single,  master  plate. 

Even  with  tubes.  Model  2  Ampec 
is  smaller  than  a  book  of  matches. 
Model  3  is  smaller  than  a  postage 
stamp — and  it  has  a  tone  circuit, 
besides! 

Ask  your  Centralab  distributor 
to  tell  you  more  about  Ampec.

ing and  treated  him  royally  in  Chinatown  after  the  meeting. 
The  San  Francisco  Radio  Club  had  John  F.  Honey,  of  the 
Stanford  Research  Institute,  as  guest  speaker  in  February. 
He  spoke  on  single  sideband.  ATO  has  been  doing  a  fine 
job  on  the  speakers  committee  and  has  excellent  features 
lined  up  for  future  meetings.  The  Club  presented  GGC  with 
a  beautiful  plaque.  Thanks  again,  gang.  The  Ladies  Club

than  300  dollars  was  spent  on  sending  out  literature  on 
Senate  Bill  #222  and  Assembly  BillT#593.  ACN  was  ap- 
pointed by  the  Central  California  Radio  Clubs  to  repre- 
sent them  as  lobbyist  at  the  legislature.  To  date  a  clause 
has  been  added  to  the  original  bill;  that  special  plates  are 
to  be  awarded  to  amateurs  with  mobile  installations  only. 
The  Cahfornia  Motor  Vehicle  Dept.  reports  that  the  lists 
sent  to  law  representatives  in  California  cost  $75  per  copy.

MMT.  RM:  KQD.  PAM;  lUF.  We  now  have  about  1100 
hams  in  Colorado  with  only  220  AREC  members.  There  is 
lots  of  room  for  improvement  so  let's  all  join  and  see  how 
close  we  can  come  to  100  per  cent.  MMT  or  your  SCM 
will  be  very  happy  to  send  out  applications,  so  just  send 
either  one  of  us  a  post  card,  and  we  will  answer  promptly. 
Also  remember  the  EC  check-in  around  the  first  of  the 
month.  OMN  has  finished  this  year's  radio  class  and  has 
three  ready  for  Novice  Class  examinations.  Ben  will  con- 
duct a  similar  class  next  fall.  WN0ZZS  and  KN0AAI  are 
two  new  Novices  from  Pueblo.  lUF  has  a  new  final.  TVI 
has  41  states  toward  WAS,  including  WIAW.  The  Colorado 
nets  have  been  having  a  lot  of  trouble  lately  with  QRM. 
Most  of  it  seems  to  come  from  hams  who  do  not  check  their 
frequency  before  transmitting.  Net  operation  is  very  im- 
portant and  can  be  done  efficiently  only  if  all  of  us  co- 
operate. The  news  was  (|uite  sparse  this  month  and  as  a

PL-6569  is  a  new  high-mu  triode,  de- 
signed especially  for  grounded  -  grid 
amplifiers.  It  is  THE  choice  for  a  1-KW 
amplifier  to  follow  a  "100-watt"  trans- 
mitter. 

Its  high  amplification  factor  (mu=45) 
and  its  high  perveance  mean  a  power 
gain  of  ten  or  more.  More  than  800 
watts  output,  with  only  75  watts  drive! 
PL-6569  is  conservatively  rated  at  250 
watts  plate  dissipation.  Its  low  plate-to- 
filament  capacitance  (O.lO^u^f)  makes 
for  real  stability  as  a  grounded-grid 
amplifier.

Angeles  County  are  participating  in  the  American  Heart 
Campaign  by  providing  mobile  units  to  pick  up  money 
from  the  volunteer  workers.  Two  W6s  were  heard  by 
5FAG,  Albuquerque,  on  Feb.  18th,  according  to  ORS,  who 
worked  FAG  on  the  21st  on  75  meters.  -Apparently  this 
was  caused  by  ionization  from  atom  blasts.  K6BAG,  the 
Mt.  Pacifico  Radio  Club,  is  scheduled  for  the  mountain  of 
tlie  same  name  next  Field  Day.  K6JLY,  publicity  secretary 
of  Hamilton  High  Radio  Club,  indicates  that  the  Club's 
constitution  now  includes  words  which  provide  for  expul- 
sion of  any  member  known  to  be  "bootlegging."  The  Oscil- 
lator, from  Long  Beach,  reminds  us  of  the  'YLRL  Convention

THE    AMERICAN 
RADIO    RELAY    LEAGUE 

Wesf  Harfford  7,  Connecticut 


ONTARIO  — SCM,  G.  Eric  Farquhar,  VE3IA  —  We 
record  with  deep  regret  two  Silent  Keys,  OW  and  AP.  OW 
was  well  known  as  a  member  of  the  Air  Transport  Board 
and  an  active  member  of  the  Ottawa  Amateur  Radio  Club. 
AP,  a  past  secretary  of  the  same  club,  and  a  member  of  the 
Dept.  of  Transport,  was  very  active  on  20,  40,  and  80 
meters.  The  Nortown  Radio  Club  of  Toronto  is  possessor 
of  the  Marconi  Trophy  for  being  top  Canadian  scorer  in 
the  1954  ARRL  Field  Day  operation.  Up  Simcoe  way  the 
Norfolk  Club  recently  held  a  banquet,  but  lack  of  informa- 
tion has  us  guessing  as  to  what  took  place.  The  annual 
banquet  of  the  Brantford  ARC  was  a  tremendous  success. 
Some  eighty  hams  who  attended,  representing  Windsor, 
Chatham,  Gravenhurst,  Elora,  Toronto,  Hamilton,  Gait, 
Kitchener,  and  Belmont,  heard  some  very  interesting  data 
on  civil  defense,  ably  iiresented  by  P.  H.  Fox,  Chief  Trans- 
port Officer  for  Canadian  Civil  Defense.  He  described  civil 
defense  as  "'a  pressing  necessity  toward  safeguarding  the 
lives  and  well-being  of  our  people  and  the  preservation  of 
that  way  of  life  wliich  we  hold  so  dearly  and  prize  so  deeply, 
within  our  hearts."  2BE,  ARRL  Canadian  Division  Direc- 
tor, who  recently  completed  25  years  of  service  to  Canadian 
Amateur  Radio  as  its  representative,  outlined  the  benefits 
derived  from  being  a  League  member.  Touching  on  the 
ARICC,  wliich  forms  communication  networks  across  Can- 
ada, he  said,  "These  are  the  boys  who  control  and  operate 
the  civil  defense  networks.  All  other  organizations  get  their 
reservoir  of  trained  personnel  from  this  organization."  TM 
changes  receivers  and  says  "There's  a  difference."  BUR 
and  his  XYL  were  seen  vacationing  down  Tampa  way.  VZ 
reports  OSN  activity  keeps  up.  A  newcomer  in  Belleville  is 
BDT.  VWI,  in  Kapuskasing,  puts  out  a  nice  signal  on  40 
and  80  meters.  BSW  reports  being  the  "first  VE  contact" 
to  about  25  Novices.  U.h.f.  fellows  are  asked  to  be  on  the 
lookout  on  the  420-Mc.  band  for  BDT,  CAB,  BEE,  and 
ASD.  Traffic:  VE3GI  172,  BUR  108,  VZ  12G,  A,TR  95,

QUEBEC  —  SCM,  Gordon  A.  Lynn,  VE2GL  —  PQN  is 
taking  a  beating  these  days  from  poor  conditions,  par- 
ticularly long  skip  making  short  hauls  difficult.  However, 
DR  continues  behind  it  with  quite  a  few  stations  reporting 
in.  The  same  difficulty  is  being  experienced  on  the  Northland 
Net,  as  reported  by  FL.  CA  reports  nothing  new,  just  lots 
of  traffic  for  the  Far  Nortli.  II  has  renewed  ORS  appoint- 
ment after  a  lapse  of  a  few  years,  this  time  from  Sherbrooke. 
The  St.  Maurice  Valley  gang  has  one  station  or  another 
covering  3075  kc.  continuously  throughout  the  day,  as  well 
as  on  3740-kc.  'phone,  on  tlie  lookout  for  traffic  for  that  way. 
Reports  from  all  parts  of  the  VE2  district  are  solicited.

as  the  OK  has  been  received  from  the  R.I.  WC  was  away

for  a  vertical  antenna.  ZR  has  been  hobnobbing  with  the 
Eskimos  and  working  from  VE8-Land.  Congratulations  to 
WO  and  his  XYL  on  the  arrival  of  a  YL  jr.  operator.  CP 
stays  up  nights  chasing  the  elusive  DX.  YE  is  active  on  the 
BC  Net.  Make  plans  now  to  attend  the  Alberta  Hamfest 
which  will  be  held  this  year  in  Lethbridge.  It  is  with  regret 
that  the  death  of  .J.J  is  reported.  A  charter  member  of  the 
Hat  Ham  Club,  his  advice  and  help  were  highly  valued.

MANITOBA  — SCM,  John  Polmark,  VE4HL  — OO: 
RB.  New  officers  of  the  ARLM  are  NW,  pres.;  MO,  treas.; 
PE,  secy.  The  Noon  Net  now  is  registered  with  the  ARRL. 
EF  is  having  trouble  with  his  20-meter  beam.  ML,  IF,  and 
JW  are  sporting  new  mobiles  all  with  very  nice  signals. 
QD  is  having  TVI  trouble.  JW  has  a  new  antenna  but  still 
has  TVI.  It  is  curling  time  so  we  don't  see  much  of  GB.  XW, 
wouldn't  it  be  better  to  stay  on  the  ground?  We  don't  have 
too  many  active  YLs  now.  No  reports  were  received  from 
the  20-meter  gang.  A  fine  time  was  had  by  all  at  the  ARLM's 
annual  "Ham  Do"  Mar.  5th.  The  ARLM  had  a  booth  at

Antenna  Coupler 

{.Continued  from  page  13) 

(Globar)  provides  a  convenient  load  for  trans- 
mitter adjustments.  Our  requirements  were  for 
power  inputs  up  to  250  watts  with  the  transmitter 
terminated  with  50  ohms;  however,  work  is  being 
done  on  a  70-ohm  version  of  the  "Z-match." 

The  transmitter  used  here  has  a  pi-network 
output  circuit  and  this  is  adjusted  for  proper 
plate  loading  with  S2  in  the  first  position,  which 
connects  the  50-ohm  dummy  load.  Power  can 
be  read  in  the  forward  position  of  the  bridge  on 
the  proper  scale.  No  reflected  power  will  be  evi- 
dent with  the  resistive  load.  The  proper  forward 
reading  scale  on  Mi  should  l)e  selected  by  means 
of  S\,  depending  on  the  power  output  of  the  trans- 
mitter. As  can  be  seen  from  the  schematic  antl 
photographs,  R2,  R3,  and  Ri  set  the  0-10-,  0-100- 
and  0-1 000- watt  full-scale  levels.  Reflected  power 
calibrations  are  automatically  taken  care  of  by 
the  settings  of  .^2,  ^3  and  Ri  when  adjusted  in 
the  forward  position. 

It  might  be  well  to  note  here  that  transmitters 
having  outputs  in  e.xcess  of  50  watts  should  be 
tuned  up  at  lower  power,  because  the  dummj^ 
load  in  the  "Z-match"  is  rated  at  50  watts  and 
e.Kcessive  power  could  ruin  the  resistor.  However, 
the  "on-the-air"  rating  of  the  "Z-match"  is 
much  higher  than  50  watts. 

The  antenna  should  be  connected  to  the  out- 
put terminals  J3  or  J^,  depending  on  the  fre- 
quency. (S2  is  then  switched  to  the  second  position 
and  Cio  and  Cn  tuned  for  minimum  reflected 
power,  as  read  on  the  meter.  The  two  controls 
will  interlock  somewhat,  but  a  few  trials  will 
readily  lead  to  a  good  null.  The  system  is  then 
ready  for  use.  In  testing  with  a  wide  variety  of 
both  antennas  and  resistive  loads,  the  reflected 
power  was  below  one  watt  in  all  cases.  After  this 
minimum  or  zero  reflected-power  reading  has 
been  obtained  no  readjustment  of  the  transmit- 
ter is  necessary  if  it  has  previously  been  adjusted 
to  work  into  the  dummy  load. 

The  tuning  capacitor  Cn  will  be  near  maximum 
capacitance  for  both  3.5-  and  14-Mc.  operation, 
while  the  setting  will  be  near  midscale  at  21  Mc. 
On  7  and  28  Mc,  the  capacitance  will  be  nearly 
at  minimum.  The  setting  of  Cio  will  vary  with 
different  loads.  In  the  third  position  of  *S2 
straight-through  operation  can  be  used,  enabling 
the  amateur  with  a  matched  50-ohm  line  to  use 
the  bridge.  The  bridge  is  an  excellent  instrument 
for  adjusting  element  lengths  on  a  beam  for 
lowest  reflected  power.

You  may  have  heard  Bob  Cheek 
on  the  DX  bands  during  the  re- 
cent DX  contest.  Bob  is  a  ham 
of  23  years  standing,  and  is 
recognized  as  an  outstanding 
DX  operator,  both  phone  and 
CW.  Like  many  hams,  Bob  finds 
that  his  "rig"  is  relaxing  and 
educational  ...  and  as  stimu- 
lating as  his  work  on  advanced 
development  projects  at  the 
Westinghouse  Electronics  Divi-

Can  a  job  be  as  interesting  as 
a  hobby?  Bob  says  it  can!  "At 
Westinghouse,"  he  contends, 
"the  combination  of  profes- 
sional surroundings,  creative 
freedom  and  challenging  'proj- 
ects of  tomorrow'  has  put  me 
in  a  real  'engineer's  heaven'! 
In  addition,  the  income  and 
employe  benefits,  fine  suburban 
living  conditions,  and  so  forth 
have  helped  both  myself  and 
my  family  achieve  many  of  our 


lifetime  goals  while  we  are  still

Results 

The  "Z-match"  has  been  in  use  at  the  writer's 
station  for  the  past  several  months  and  the  results 
have  been  excellent  on  all  bands  from  3.5  to  30 
Mc.  Two  transmitters  have  been  used.  One  is  a 
Harvey- Wells  T-90  Bandmaster  running  between 
75  and  90  watts  input  on  hoih  c.w.  and  'phone. 
The  second,  with  a  pair  of  4-65As  in  the  final 
running  inputs  up  to  300  watts,  has  been  used 
with  no  apparent  breakdown  of  capacitors,  coils 
or  the  Z  bridge.  The  first  transmitter  utilizes  a 
pi-network  output  tank,  and  after  tuning  this 
properlj'  on  any  band  into  the  50-ohm  load,  no 
retuning  is  necessary  after  the  "Z-match"  is 
tuned  for  minimum  reflected  power.  The  second 
transmitter  uses  an  all-band  tank  with  series- 
tuned  link  output  and  the  results  were  the  same 
with  this  output  circuit.  The  fact  that  retuning 
the  transmitter  is  not  required  after  tuning  the 
coupler  for  zero  reflected  power  indicates  a  defi- 
nite impedance  match. 

Although  the  functions  of  the  "Z-match"  have 
been  described  in  terms  of  matching  the  trans- 
mission line  to  a  coax  line  to  the  transmitter,  it  is 
equally  useful  for  coupling  the  line  to  a  receiver. 
The  same  antenna  is  used  for  both  transmitting 
and  receiving  at  the  writer's  station,  and  received 
signals  have  been  given  a  tremendous  boost  by 
the  use  of  this  coupler,  mainlj^  because  the  re- 
ceiver has  a  nominal  input  impedance  of  50  ohms 
and  its  antenna  terminals  are  finally  looking  at 
the  proper  impedance.  The  send-receive  switch- 
ing is  of  course  done  in  the  coax  link. 

After  operating  conventional-type  antenna 
couplers  with  no  visual  means  of  obtaining  a 
match,  we  wonder  how  many  times  a  mismatch 
has  been  tolerated.  Quite  often,  we  think,  at  this 
station,  because  the  percentage  of  contacts  for 
stations  called  has  gone  up  tremendously  since 
the  installation  of  the  "Z-match,"  and  in  the 
recent  DX  contest  the  speed  of  tuning  helped  in 
running  up  the  best  score  we  ever  had,  on  both 
'phone  and  c.w.

drop  out  at  the  same  positioning  of  the  sensitivity 
control,  no  balance  adjustment  is  necessary.  If 
one  relay  drops  out  before  the  other,  the  balance 
control  should  be  adjusted  for  simultaneous  oper- 
ation of  Ki  and  K2.  Following  adjustment  of  the 
l)alancc  control,  the  sensitivity  control  may  be  ad- 
justed for  optimum  sensitivity.  This  system  may 
be  made  sufficiently  sensitive  to  respond  to 
carrier  shift  brought  about  by  nonlinear  modu- 
lation and  slight  overmodulation  excursions  and 
to  antenna  detuning  caused  by  passing  pedes- 
trians, automobiles  or  any  phenomena  causing 
even  the  slightest  antenna  r'otuning  effect.  Nor- 
mal sensitivity  adjustment  is  a  matter  of  choice 
and  will  vary  with  individua  operating  require- 
ments. R3  should  not  be  adjusted  to  the  point 
where  Ki  and  K2  are  energized  simultaneously. 
Such  an  adjustment  renders  the  tuning  motor 
inoperative. 

Sensing  of  this  sj'stem  may  be  changed  by  re- 
versal of  the  output  and  input  coaxial  connectors. 
Reversal  of  the  tuning-unit  operation  may  be 
obtained  by  reversal  of  the  two  control  leads 
from  the  remote  control  unit.  In  normal  opera- 
tion, series  inductance  is  automatically  added 
with  a  capacitive  antenna  and  inductance  re- 
duced with  an  inductive  load. 

A  great  deal  of  satisfaction  in  mobile  operating 
has  been  brought  about  by  the  use  of  this  system. 
It  is  a  real  pleasure  to  QSY  about  the  40-  and 
75-meter  bands  without  the  worry  of  antenna 
resonance,  and  to  be  confident  that  no  matter 
what  the  position  of  the  mobile  whip  —  it  is 
resonant.

Using  the  Two-Tone  Generator 

If  the  generator  is  used  to  test  an  s.s.b.  exciter 
equipped  with  a  high-impedance  microphone  in- 
put circuit,  it  will  be  desirable  to  divide  down  the 
output  signal  by  means  of  a  circuit  such  as  shown 
in  Fig.  4.  If  an  input  terminal  or  jack  for  audio

put of  the  generator  to  ground,  a  blocking  ca- 
pacitor should  be  used  if  one  is  not  employed  in 
the  equipment  under  test. 

Two-tone  test  procedures  have  been  outlined 
in  references  (2),  (3)  and  (4).  (See  p.  124.)

In  the  preceding  paragraphs  considerable  em- 
phasis has  been  placed  on  minimizing  distortion. 
Low-distortion  test  signals  are  especially  impor- 
tant when  testing  phasing  types  of  transmitters 
because  distortion  on  the  test  signal  produces 
sideband  components  in  the  region  of  desired 
sideband  suppression. 

Another  point  which  is  worthy  of  consideration 
when  evaluating  the  performance  of  the  phasing- 
type  exciter  is  the  absolute  phase  shift  in  the 
yO-degree  audio  phasing  network  at  the  two  test 
freciuencies  used.  Reference  (5),  which  discusses 
a  typical  phasing  network,  indicates  a  possible 
variation  of  about  ±1.3  degrees  phase  shift  over 
a  frecjuency  range  of  225  to  2750  c.p.s.  For  best 
results  it  is  therefore  desirable  to  select  two  test 
frequencies  such  as  to  produce  equal  phase  shift; 
this  results  in  equal  suppression  at  each  frequency 
and  minimizes  any  slight  ripple  modulation 
which  would  otherwise  be  superimposed  on  the 
two-tone  envelope  output.  Slight  variation  in 
components  of  one  of  the  two  oscillators  may  be 
made  in  this  case  so  as  to  obtain  a  pair  of  fre- 
quencies fulfilling  the  above  requirement. 

The  two-tone  test  generator  is  simple  and  in- 
expensive to  construct  and  is  believed  to  be  a 
very  worth-while  addition  to  the  test  equipment 
used  by  the  s.s.b.  and  a.m.  man.

any  new  dot  selection  made  before  the  dash

through  circuit  symmetry. 

With  their  interlocks  and  activation  circuits, 
7io  and  Fii  comprise  effectually  a  tri-stable  sys- 
tem. Either  one  or  the  other  tube  may  be  con- 
ductive, but  never  both.  However,  both  tubes 
may  be  nonconductive.  The  three  conditions  cor- 
respond to  selection  of  dot,  dash,  and  spacing 
characters.  Bj^  itself,  this  structure  guarantees 
that  a  given  character  will  be  held  in  storage  if  an 
opposite  t>'pe  character(s)  has  been  priorly 
selected,  and  it  will  not  be  released  until  that

side  to  the  other  this  delaj'  guarantees  that  both 
memories  are  not  cleared  by  the  same  clearance 
pulse  and  that  both  generating  triggers  aie  not 
tripped  by  the  same  time-base  pulse.  Without 
capacitive  delay  this  would  occur,  since  generator 
trip,  memory  clearance  and  sequence  transfer  are 
virtually  simultaneous. 

Sequence  Seizure 

Thus  far,  a  given  sequencor  tube  cannot  be 
activated  by  its  associated  memory  or  key  until 
the  opposite  sequencor  is  released  by  both  its 
key  and  memory,  because  of  the  interlock  func- 
tion. I'g  and  Fi2  generate  seizure  pulses  to  over- 
ride the  interlocks  in  such  a  manner  that  the 
output  exacth'  follows  the  order  of  selection, 
regardless  of  subsequent  key  manipulations  or 
holdings.  The  crisscross  grid  and  cathode  con- 
nection to  the  memories  results  in  nonconduction 
in  both  tubes  if  both  memories  are  clear  or  if 
both  memories  are  actuated,  and  conduction  in 
one  of  the  tubes  when  the  memory  associated 
with  its  grid  is  actuated  and  the  other  memory  is 
clear.  This  obtains  from  the  following  potentials 
in  the  memories:  actuated  —  cathodes  -t-U 
volts,  junctions  RuRzs  and  RioRn  +1  volt; 
clear  —  cathodes  4-1.3  volts,  Rz^Rss  and  it!4o/?4i 
—  17  volts.  When  both  memories  are  actuated, 
RziRis  and  R^qRh  rise  to  -+-3  volts  as  the  grid- 
current  loading  in  Fg  and  Vn  is  removed. 

Assume  the  dot  and  dash  keys  closed  in  that 
order  before  any  output  starts,  with  onlj^  the 
dot  key  held  closed.  Without  seizure  the  closed 
dot  key  would  hold  the  sequencor  after  the  first 
dot  on  +10  volts  from  RziRz%  for  continuous  dot 
output,  and  the  stored  dash  would  not  appear  in 
the  order  of  selection.  However,  when  the  dot 
memory  clears,  its  cathode  (and  that  of  Fg)  drops 
to  +1.3  volts  and  Fg  conducts  as  a  result  of  the 
+ 1  volt  on  its  grid  from  the  actuated  dash  mem- 
or}^  Cg,  slowly  reverse  charged  by  R\-j,  charges 
through  Fg  and  R\^.  This  momentarily  reduces 
R19R20  from  +12  to  —7  volts,  to  cut  off  Fio  by 
pulling  down  the  dot-holding  potential  at  DzR<>\. 
Junction  i?28^29  momentarily  rises  to  +12  volts 
while  Fio  is  cut  off.  The  positive  selection  poten- 
tial from  the  actuated  dash  memorj^  seizes  Fn 
via  /?26  while  R2SR29  is  positive,  and  conduction  in 
Fii  permanently  holds  i?igi?20  at  negative  inter- 
lock potential  to  isolate  the  closed  dot  key.  Thus 
sequence  control  has  been  transferred  to  the 
dash  side  despite  the  closed  dot  key,  and  the 
next  output  character  will  be  the  dash.  Wlien 
the  dash  memory  clears,  the  still-closed  dot  kej^ 
will  reestablish  Fio  conduction  for  dot  output. 
If  both  keys  have  been  held  closed,  the  dash 
hold  potential  will  retain  control  of  the  se- 
quencor, since  the  dot  memory  is  now  clear  and 
no  pulse  will  be  generated  by  F12C10  when  the 
dash  memory  clears  in  the  presence  of  an  already- 
cleared  dot  memory. 

Assume  that  the  dash  key  is  not  closed  until 
after  the  first  dot  (or  any  dot  of  a  series)  has 
started.  The  dot  memory  will  be  clear  at  this 
time  with  Fio  conducting  on  the  +10  volts  from 
the  closed  dot  key.  The  cathode  of  Fg  stands  at

+  1.3  volts  and  that  tube  will  conduct  immedi- 
ately when  the  dash  memory  is  activated,  seizing 
the  spquencor  as  before. 

In  both  cases,  with  both  keys  held  closed,  the 
subsecjuent  output  is  a  series  of  dashes  until 
either  the  dash  key  is  released  or  the  dot  key  is 
released  and  redosed.  After  clearance  of  the  dash 
memory,  release  of  the  dash  key  applies  —13 
volts  to  the  grid  of  Vn  and  initiates  a  simple 
seciuencor  transfer  to  the  -|-10  volts  from  the 
closed  dot  key.  Opening  and  reclosing  the  dot 
key  with  the  dash  key  still  closed  actuates  the 
dot  memory  for  a  F12C10  seizure,  and  the  output 
switches  to  dots.  The  opposites  of  these  seizure 
actions  olitain  from  symmetry. 

Summary  of  SMS  Functions 

1)  Momentary  closure  of  a  key  actuates  the 
associated  memory.  The  memory  directs  an 
activating  potential  toward  the  associated 
sequencer. 

2)  Continued  closure  of  a  key  directs  an 
independent  holding  voltage  toward  the  asso- 
ciated sequencor.  This  hold  potential  is  effective 
only  after  the  associated  memory  has  assumed  or 
seized  control  of  the  sequencor. 

3)  Actuation  of  a  memory  with  the  opposite 
key  and  memory  idle  assumes  control  of  the 
sequencor,  isolating  the  opposite  memory  and 
hold  potentials. 

4)  Actuation  of  a  memory  seizes  control  of 
the  sequencor  over  continuously  closed  opposite 
key  hold  potential,  if  the  opposite  memory  is 
clear. 

5)  Actuation  of  a  memory  does  not  take  con- 
trol of  the  sequencor  over  an  actuated  opposite 
memory. 

6)  Clearance  of  a  memory  whose  key  is  closed 
allows  an  actuated  opposite  memory  to  seize 
control  of  the  sequencor  over  the  hold  potential 
from  that  closed  key. 

7)  Clearance  of  a  memory  whose  associated 
key  is  closed  does  not  relinquish  control  to  an 
opposite  closed  key  whose  associated  memory  is 
not  actuated. 

8)  In  the  absence  of  any  actuated  memories, 
release  of  one  key  after  both  keys  have  been  held 
closed  places  the  sequencor  under  control  of  the 
still-closed  key. 

Summary  0/  Actions  0/  the  Keys 

1)  A  single  character  is  generated  by  momen- 
tary or  prolonged  closure  of  a  key.  The  character 
is  held  by  the  memory  for  a  positive  time-base 
pulse  if  the  key  is  released  prior  to  that  pulse. 

2)  Successive  like  characters  are  generated  by 
constant  closure  of  a  key. 

3)  When  one  memory  is  already  actuated, 
closure  of  the  opposite  key  before  generation  of 
the  first-stored  character  activates  the  opposite 
memory.  The  firstly  actuated  memory  retains 
control  of  the  sequencor  until  one  character  of 
its  type  is  delivered  at  the  output.  The  secondly 
actuated  memory  then  assumes  control  of  the  se- 
quencor (as  the  first  key  is  open  or  still  closed)  and 
the  next  output  character  is  of  the  second  type.

4)  Continued  closure  of  this  second  key  main- 
tains control  of  the  sequencer  after  the  transfer 
action,  and  the  output  is  a  scries  of  the  second 
type  until  that  key  is  released.  This  obtains  even 
with  the  fu'st  key  still  closed. 

5)  Release  of  the  second  key,  with  the  first  key 
still  closed,  causes  the  output  to  revert  to  the 
first  character  type. 

6)  Release  and  reclosure  of  the  first  key  (just 
a  flick!)  reactuates  the  first  memory  and  seizes 
control  of  the  sequencer  —  the  second  key  closed 
all  the  while  —  and  the  output  reverts  to  the  first 
character  type  until  that  first  key  is  again  re- 
leased or  until  the  opposite  type  character  is 
flicked  in  by  the  second  kej'.  At  least  one  charac- 
ter of  the  first  type  is  guaranteed  by  the  memorj'. 

7)  In  recapitulation,  any  closure  of  a  key 
guarantees  at  least  one  character  of  that  tj^pe, 
transmitted  in  correct  relationship  to  the  order 
of  closure,  regardless  of  intervening  selective 
motions.  \Vhenever  a  key  makes  contact,  the 
output  subsequent  to  the  character  in  progress 
corresponds  to  that  key  until  the  other  key  makes 
contact  or  the  first  key  is  released. 

With  automatic  spacing,  perfect  characters, 
and  memory  and  seizure  leeways,  all  the  operator 
has  to  do  is  spell.  With  a  few  more  tubes,  the 
kej'er  might  be  tied  in  to  a  dictionary. 

D.C.  Output 

To  eliminate  the  one  relay,  the  circuit  modifi- 
cation of  Fig.  3  (Part  I)  can  be  applied.  With  this 
circuit,  V3  conducts  during  spacing  and  its  plate 
stands  120  volts  negative  wnth  respect  to  ground. 
Cut-off  voltage  from  —30  to  — 120  is  available  at 
the  arm  of  R2,  for  control  of  a  vacuum-tube  keyer. 
/?3  protects  the  memory  clearance  junction 
R1R2  from  loading  effects  by  connected  equip- 
ment and  also  serves  as  the  key-click  filter 
resistance. 

The  plate  of  Vs  drops  60  volts  on  marking, 
transmitting  a  60-volt  negative  pulse  via  Ci  to 
the  grid  of  V3.  The  CiRi  time  constant  is  suffi- 
ciently long  to  hold  F3  cut  off  for  a  2-w.p.m. 
dash.  With  V3  cut  ofT  the  output  load  stands  at 
ground  potential,  marking  condition  for  the 
standard  vacuum-tube  keyer. 

Heavy  line  surges  can  produce  as  much  as  10 
volts  negative  swing  across  Rt.  The  24-volt 
positive  grid  return  of  F3  to  R^Rq  ensures  that 
these  surges  do  not  appear  in  the  output.  Since 
the  generator  and  SMS  trigger  configurations  are 
quite  independent  of  source  voltage,  they  are 
stable  in  the  presence  of  any  surge  short  of  com- 
plete outage.  Use  of  this  output  circuit  demands 
that  F3F4  be  at  the  absolute  ground  end  of  any 
heater  strings.  Even  though  the  12AU7  heater- 
cathode  insulation  is  rated  at  180  volts,  the  maxi- 
mum point  is  approached  in  V3  when  the  line 
voltage  exceeds  125. 

(Scramble  in  Part  I,  April,  1955,  QST:  Page

The  NEW 

ELDICO 

VFO  10/20A 

Variable  Frequency  Oscillator 
for  80  and  20-meter  Bands 

Designed  expressly  for  Central  Electronics  SSB  Exciters 
(Models  lOA.  lOB  and  20A).  Provides  complete  band 
coverage  on  80  and  20  meters.  No  modification  of  Exciters 
is  required. 

Each  band  is  accurately  calibrated  and  divided  into  two 
sections  selected  by  a  front  panel  switch.  Has  6-inch  dial. 
Provides  approximately  5  inches  of  bondspread  on  75- 
meter  phone  bond  and  3  inches  on  20-meter  phone.  Sturdy 
cabinet  construction  and  rugged  mounting  of  components 
achieve  maximum  mechanical  stability.  Electricol  stability 
is  attained  through  the  use  of  circuit  employing  high-Q  in- 
ductor and  a  precision  geared  tuning  condenser.  There  are 
no  tubes  in  the  VFO  proper,  hence  no  heat  to  cause  drift. 
A  single  tube  (6BA6)  oscillator  unit  plugs  directly  into 
octal  socket  on  C.E.  Exciters.  The  only  external  connection 
is  a  single  coax  line  from  the  exciter  to  the  VFO.

Beginner's  Receiver 

{Continued  from  page  32) 

choke  lead.  Four  leads  are  brought  out  from  the 
power  supply  to  connect  to  the  receiver:  the  two 
heater  leads,  the  B  +  lead,  and  the  B  —  lead. 

When  the  power  supply  is  wired  and  the  leads 
connected  to  the  receiver,  the  unit  is  ready  for 
testing. 

Testing  and  Using  the  Receiver 

If  you  already  have  an  antenna  strung  up, 
connect  the  end  of  it  to  Terminal  2  —  the  one 
connected  to  the  rotor  of  Ci.  If  you  don't  have 
an  antenna,  any  wire,  20  to  40  feet  long  or 
longer,  can  be  strung  up.  An  outside  antenna  will 
perform  better  than  one  indoors,  although  you'll 
hear  plenty  of  signals  with  a  wire  just  strung 
around  the  room. 

Connect  your  headphones  to  the  tip  jacks  and 
plug  in  the  80-meter  coil.  Plug  the  power  cord 
into  the  115-volt  a.c.  line  and  watch  the  6U8 
to  see  if  the  heater  lights  up.  If  it  doesn't,  turn 
off  the  power  and  check  your  wiring  from  the 
power  suppl}^  to  the  heater  pins,  4  and  5,  on  the 
6U8  socket. 

The  receiver  wall  only  take  a  minute  to  warm 
up.  Turn  the  regeneration  control  and,  at  one 
point,  3^ou  should  hear  a  change  in  the  character- 
istic of  the  noise.  This  is  the  point  where  the 
receiver  starts  to  oscillate.  Tune  the  general- 
coverage  condenser  slowly  and  you  should  hear 
signals.  Leave  the  capacitor  set  at  or  near  one

Take  The  Fuss  Out  of  Switching  Circuits 


Now  you  can  eliminate  the  fumbling 
and  annoyance  of  screwing  and  unscrew- 
ing coax  connections.  With  B&W's  new 
Model  550  coaxial  switch,  you  can  in- 
stantly select  antennas,  transmitters,  ex- 
citers, receivers,  and  other  r-f  generating 
devices  merely  by  turning  a  knob. 

This  new  multi-position  coaxial  switch 
has  six  S0239  connectors  for  selecting  any 
one  of  five  52  or  75  ohm  lines.  It  will 
handle  up  to  1  kw  of  modulated  power 
with  a  maximum  crosstalk  of  -45  db  at  30  mc.  Housed 
in  a  2M"  diameter  aluminum  case,  the  unit  is  de- 
signed for  single  hole  mounting.

of  the  signals  and  then  tune  the  bandspread  ca- 
pacitor. This  capacitor  gives  a  slower  tuning 
rate,  making  it  much  easier  to  tune  in  signals. 

With  a  signal  tuned  in,  rotate  the  antenna- 
trimmer  control  and  the  signal  should  get  louder 
at  one  point.  If  it  doesn't,  change  the  antenna  to 
terminal  number  1  and  short  terminals  2  and  3 
together  with  a  short  piece  of  wire.  Try  the 
antenna  trimmer  again,  and  j^ou  should  find  that 
the  signal  will  peak  up.  The  regeneration  control 
setting  may  have  to  be  changed  to  maintain 
oscillation. 

Locating  the  amateur  Novice  bands  is  simple. 
Tune  the  receiver  until  you  find  an  amateur 
'phone  station.  The  Novice  band  on  Ijoth  80  and 
40  meters  is  immediately  below  the  'phone  Inxnds. 
To  tune  lower  in  frequency  than  the  'phone 
bands,  the  bandspread  capacitor  is  turned  so 
that  the  capacitance  increases,  or  the  plates 
mesh. 

The  beginner  will  find  great  satisfaction  in 
completing  the  receiver  and  many  happy  hours 
of  listening  will  be  his  for  the  asking.

advanced  in  design,  modern  in  circuitry.  It  covers  a  continuous 
frequency  range  from  1.7  to  54  mcs  and  may  be  operated  xtal 
control  OS-is  or  v/ith  the  Gonset  VFO.  A  6146  output  tube  and 
two  7C5's  as  modulators  permit  plate  voltages  of  400  to  500 
volts— inputs,  (modulated)  to  50  watts.  Two  high  Q  coils  provide 

coverage  of  75-40-20-15-11  and  10  meter  amateur  bonds  and 
are  readily  changed  from  front  of  housing.  The  output  circuit 
eliminates  loading  problems  frequently  present  with  pi  networks 
where  the  load  is  a  short,  loaded  mobile  antenna.  Circuit  also 
couples    into    balanced    or    unbalanced    lines,    can    be    quickly 

converted  to  "Pi"  or  "L"  networks  by  simple  wiring  change. 
Driver  is  bandswitched.  The  Commander  uses  any  standard 
carbon  or  PA-type  dynamic  or  crystal  microphone.  No  preomp 
required. 

An  excellent  VFO  is  available  os  a  companion  unit  for  the  Com- 
mander. This  Is  an  extremely  stable,  low  drift  unit  and  uses  no 
tubes— requires  no  operating  voltage— coax  cable,  (furnished) 
plugs  Into  fitting  on  Commonder  panel.  Unit  covers  75-40-20-15-

financially  able  to  buy  a  super-selective  receiver  at  the  first 
chance.  Each  'phone  station  takes  up  more  room  than  a  few 
c.w.  stations.  If  the  'phone  station  is  stronger  than  the  c.w. 
station,  it  will  blank  it  out.  Furtlxermore,  since  Novices  arc 
crystal-controlled,  they  are  not  able  to  change  frequency  so 
readily  when  'phone  or  other  QRM  appears.

Editor,  QST: 

I  wish  to  take  issue  with  the  viewjjoints  taken  by  Messrs. 
Clark  and  Brogdon  in  March  QST.  Both  of  these  letters 
seem  to  indicate  signs  of  the  so-called  "progressive"  view- 
point prevalent  in  amateur  circles. 

I  agree  with  Mr.  Clark  in  condemning  the  use  of  c.w.  in 
tlie  'phone  bands;  it  is  definitely  an  ungentlemanly  prac- 
tice. But  the  reason  is  not  that  c.w.  was  here  first.  The  same 
argument  could  be  applied  to  argue  that  spark  was  here 
first  so  it  should  be  allowed.  As  has  been  pointed  out  before, 
c.w.  is  necessary  in  case  of  communications  emergency  or 
breakdown  of  speech  equipment,  so  it  is  necessary  to  have 
c.w.  allowed  everywhere  (on  the  hambands  that  is).  This 
does  not  give  c.w-.  operators  the  right  to  use  normally- 
assigned  'phone  channels,  the  reason  being  courtesy  to  the 
'phone  men. 

Mr.  Brogdon  carries  his  "progressive"  ideas  a  bit  too  far. 
Granted  that  "sideband"  is  a  more  efficient  form  of  com- 
munication. But  how  many,  in  spite  of  the  technical  niceties, 
are  on  s.s.b.  compared  to  those  on  double-sideband?  For 
that  matter,  a  kilowatt  is  technically  superior  to  50  watts 
for  reliability  and  readability  of  communication  but  are  50- 
watt  rigs  outlawed?  The  factor  that  makes  for  outlawing 
something  should  be  the  will  of  the  majority  of  hams,  not 
how  closely  some  new  system  approaches  perfection.

Editor,  QST: 

...  I  too  came  up  through  the  Novice  ranks;  I  too  am 
disgusted  with  the  shenanigans  to  be  heard  on  the  75-meter 
'phone  band;  but  please,  I  say  please,  don't  ask  for  five 
hundred  kilocycles  of  unidentified  carriers,  sloppy  splatter- 
band  operators,  etc.  .  .  .  Admitted,  there  are  always  a 
few  c.w.  signals  to  be  found  in  the  'phone  bands,  also  ad- 
mitted that  there  are  quite  a  few  lids  running  "kilowatts." 
Nothing  has  sounded  as  jolly  as  the  character  from  Ohio 
heard  for  several  evenings  calling  "CQ  eighty"  on  the  so- 
called  wide-open  c.w.  portion  of  the  band! 

As  you  have  assumed,  I  am  primarily  a  c.w.  man,  part 
Scotch,  yes,  with  a  full  25  watts  on  80  meters.  I  wouldn't 
be  caught  dead  in  your  end  of  the  band,  because  I  don't  have 
the  patience  or  the  experience  to  make  me  feel  eligible  to 
work  a  band  which  I  always  recall  as  the  Happy-Hunting 
Grounds  for  the  old-timers  of  this  business.

C.W.-BAND  S.S.B. 

2029  Hopkins  Court 
Alameda,  Calif. 
Editor,  QST: 

After  reading  the  pros  and  cons  of  a.m.  'phone  vs.  s.s.b. 
in  the  March  issue  from  some  of  our  (ugh)  brothers,  some 
of  the  heated  arguments  are  rather  nauseating. 

I  think  both  a.m.  and  s.s.b.  definitely  have  their  place 
in  amateur  communications  if  operated  properly  and  I  have 
heard  some  poor  excuses  for  both.  Some  operators  have  the 
idea  that  s.s.b.  operation  eliminates  the  possibility  of  TVI, 
BCI,  and  even  improper  operation,  but  this  to  me  is  only  an 
admission  of  ignorance.  I  have  heard  extremely  wide  signals 
complaining  of  the  other,  while  operating  close  to  each 
other. 

The  a.m.  'phone  men  complain  naturally  about  s.s.b.  and 
c.w.  signals  in  the  'phone  portions  of  bands,  and  I  agree 
with  them  in  many  respects,  but  I  think  the  fault  lies  with

the  FCC  in  allocating  such  large  portions  of  the  bands  to 
c.w.  operation  and  small  portions  to  the  more  useful 
means  of  communications,  a.m.  'phone.  If  the  c.w.  and  s.s.b. 
boys  continually  pat  themselves  on  the  back  for  operating 
on  such  small  segments  then  maybe  they  would  like  to 
liave  less  and  be  forced  to  operate  in  what  tlie  a.m.  boys  are 
using  now. 

It  is  my  belief  tliat  if  s.s.b.  were  forced  to  operate  in 
separate  portions  of  tlie  band  from  a.m.  tliey  would  have 
many  more  join  them  in  true  progress.  The  a.m.  boys  would 
leave  the  crowded  'phone  segments  to  enjoy  the  merits  of 
s.s.b.  This  may  not  lay  too  well  on  the  s.s.b.  boys'  stomachs 
at  first  but  think  it  over  boys,  it  would  be  wonderful  to 
operate  s.s.b.  in  the  c.w.  bands.  It  is  a  nuisance  to  try  to 
operate  a.m.  and  have  a  s.s.b.  close  in  frequency.  Also,  it 
must  be  tough  for  s.s.b.  boys  to  be  repeatedly  referred  to  as 
"voice  modulated  key-clicks." 

So  it  all  boils  down  to  this:  we  are  not  getting  any  place 
beating  each  other  on  the  head,  trying  to  convert  a.m.  to 
s.s.b.,  preaching  lengthy  sermons  over  the  air,  and  committing 
the  very  act  of  libel  and  slander.  The  only  reason  for  rivalry 
between  s.s.b.  and  a.m.  is  because  we  are  guilty  as  poor 
representatives  and  members  of  ARRL  properly  to  govern 
ourselves  and  correctly  allocate  bands  for  proper  operation. 
Instead  of  fighting  each  other  we  should  exert  all  our  force 
to  allow  s.s.b.  to  operate  in  the  c.w.  bands  and  let  the  a.m. 
boys  have  tlieir  segment  in  peace.

were  handled  by  the  Federal  Radio  Commission  between 
1927  and  1934.  However,  some  of  us  who  originally  obtained 
our  amateur  and  commercial  tickets  from  the  Radio  Divi-

I  also  recall  that  originally  the  FRC  was  created  by  Con- 
gress in  1927  to  bring  order  out  of  the  chaos  in  the  broadcast 
field.  At  that  time  its  life  was  only  going  to  be  for  one  year, 
yet  like  many  other  Washington  agencies  that  came  along 
later,  they  imitated  the  "Man  Who  Came  to  Dinner"  and 
picked  up  additional  duties  along  the  way.  That  is  how  they 
got  amateur  affairs  in  1932.  Then,  in  1934,  Congress  straight- 
ened out  the  whole  thing  by  creating  the  Federal  Communi- 
cations Commission. 

It  is  refreshing  to  read  an  article  that  compares  today's 
activities  with  earlier  days. 

—  Lester  C.  Harlow,  W4CVO/I 
[Editor's  Note  —  OM  Harlow  is  correct.  The  story  ap- 
peared in  Sept.  1932  QST.] 


ONE  SOLUTION 

Rt.  1,  Box  82.-> 
Tigard,  Ore. 
Editor,  QST: 

.  .  .  True  —  tliere  is  a  lot  of  QRM  these  days,  but  why 
not  solve  it  nicely  instead  of  trying  to  either  change  the 
rules  or  shove  other  amateurs  around.  Since  one  of  the  prides 
of  being  an  American  amateur  is  to  be  flexible  and  help  witli 
many  new  "firsts "  in  radio,  wouldn't  the  best  solution  be  to 
improve  your  own  operating  techniques  first  and  then  try 
to  help  the  other  fellow  instead  of  drowning  him  out. 

Many  hams  in  this  area  have  taken  their  rigs  "upstairs" 
and  are  finding  a  new  world  in  v.h.f.;  c.w.  for  me  on  80  and 
40,  and  'phone  on  2  —  and  you  can't  ask  for  better  ham 
radio  when  you  practice  good  operating  principles. 

—  Jim  Strickland,  W7SEZ

and  OM  W4HHH.  .  .  .  W5SYL,  Iva,  was  one  of  some  100 
YLs  and  OMs  who  assisted  in  the  search  for  the  body  of 
WoDM,  pilot  of  a  plane  which  crashed  in  Texas.  .  .  .  And 
in  Lancaster,  Calif.,  K6HWB,  Vivian,  stayed  on  the  air 
for  more  than  20  hours  monitoring,  relaying,  and  keeping 
399.5  kc.  clear  during  a  search  for  a  Douglas  jet  test  pilot  on 
(Contitiuid  on  page  ISO) 


Devotees  of  amateur  radio  come  younger  all  tlic 
time.  Here's  one  chap  who  was  exposed  to  7.5-metcr 
QRM  at  the  innocent  age  of  several  hours. 

For  five  days  following  the  birth  of  son  Mark  Eric  in 
Januarv,  Mildred  Drummond,  \^'0GXG,  kept  three 
schedules  daily  with  OM  \^  0BWP,  Rev.  Wesley  J. 
Drummond,  pastor  of  the  Second  Presbyterian  Church, 
Flandreau,  S.  Dak.  Mildred's  transmitted  instructions 
on  household  matters  were  dutifully  carried  out  at  home 
by  her  OM,  11-year-old  son  John,  WN0TLR,  and 
9-year-old  daughter,  Darlene. 

We  note  with  womanly  interest  that  it  is  becoming 
fairly  common  practice  lor  mothers-to-be  to  pack  a 
portable  transmitter  and  receiver  with  a  suitcase  to  take 
to  the  hospital  for  a  maternity  confineraenl.  Seems  op- 
portune for  a  few  days  of  leisurely  (?)  QSOing.

Take  a  teen-ager  and  her  mother,  both  licensed  ama- 
teurs, and  you  can  virtually  see  the  mutual  pride  that 
exists  between  them.  Add  a  teen-age  brother  and  a  father 
with  tickets,  and  you  have  a  situation  that  any  therapist 
would  recommend  for  family  happiness.  In  the  case  of 
the  Hansen  family  of  Cheney,  Wash.,  mother  Rosella, 
W  7ULK,  interested  in  radio  for  twenty  years,  got  her 
license  first,  built  a  transmitter  and  started  teaching  her 
family.  Daughter,  son,  and  husband  followed  with  the 
calls  JTiVZs  VWU,  VWZ,  and  \^  VA  respectively.  An 
ex -schoolteacher,  Rosella  has  been  coaching  a  number 
of  teen-agers  who  aspire  to  become  hams.  She  recently 
worked  her  daughter  for  her  100th  QSI,  and  a  YL  Cen- 
tury Certificate. 


Jan.  1.3th.  Twenty-seven  amateurs  and  11  mobile  units 
helped  locate  the  pilot  witliin  48  hours.  .  .  .  K6DEN, 
Evelyn,  is  on  20  and  75  'phone  regularly  from  Redwood 
City.  ...  At  a  March  meeting,  committee  chairman  for 
the  first  YLRL  International  Convention  gave  various 
progress  reports.  It  was  announced  that  a  fashion  show 
would  be  staged  during  the  luncheon  on  June  25th.  .  .  .  We 
regretfully  note  the  untimely  passing  of  Neva  Josephine 
Fredenburg,  W6YXI,  and  her  husband  John,  W6VJQ.  The 
couple  perished  when  their  automobile  collided  with  an- 
other near  Alpine,  Calif.  A  charter  member  of  the  San  Diego 
YLRL  unit,  Neva  was  past-jiresident,  vice-president,  and 
secretary.  Owners  of  a  radio  and  TV  store  in  San  Diego, 
Neva  and  John  were  particularly  active  in  AREC  and  c.d. 
activities.  They  will  be  missed  by  their  many  friends.

DXCC  NOTES 

Announcement  is  hereby  made  of  the  addition 
to  the  ARRL  Postwar  Countries  List  of  two  new 
countries.  For  purposes  of  identification  these  will 
appear  on  the  list  as  Saint  Martin  and  Sint  Maar- 
ten.  Saint  Martin  will  encompass  all  French  terri- 
tory within  the  limits  of  17  and  19  degrees  north 
latitude  and  62  and  64  degrees  west  longitude. 
Sint  Maarten  shall  serve  to  designate  Netherlands 
territory  within  these  same  boundaries. 

DXCC  credit  will  be  given  starting  Julj'  1, 
1955,  for  creditable  confirmations  dated  on  or 
after  November  15,  1945.  This  will  permit  foreign 
amateurs  to  start  receiving  credits  at  the  same 
time  as  those  in  U.  S.  A.  Confirmations  received 
prior  to  July  1,  1955,  for  these  countries  will  be 
returned  without  credit. 

In  future  ARRL  DX  Competitions,  those 
making  contact  with  amateur  stations  located 
in  either  Saint  Martin  or  Sint  Maarten  may 
claim  credit  for  a  separate  country  in  accordance 
with  DXCC  rules.

THE     NOVICE     PRICE      RANGE 


^ENDS  correctly  timed  signals  from  5  words  to  70  words  per  minute.  Sixteen  lessons. 
^  Its  110  volt  AC.  motor  makes  it  hold  an  even,  steady  speed.  Code  is  received  on  the 
air  over  headphones;  therefore,  it  should  be  learned  with  oscillator  and  headphones.  Further- 
more, an  oscillator  is  an  excellent  device  with  which  to  learn  sending. 

^OU  get  TELEPLEX  TWO  PHASE,  STEP  BY  STEP  instruction   That  means  first  you  train  your  EAR  to  HEAR 
/'  the  signals  in  the  same  manner  you  hear  spoken  words.  You  learn  only  a  few  letters  at  a  time.  You  advance  step  by 
step  in  an  orderly  manner.  You  may  select  for  concentrated  practice  characters  that  give  you  trouble.  You  are  never 
confused  by  jumping  from  one  character  to  another  without  sufficient  time  to  thoroughly  learn  the  sound. 

You  get  plenty  of  cipher  groups  that  you  will  never  memorize.  Speed  up  to  25  words  "is  child's  play  with  TELEPLEX. 
Forty  to  fifty  words  certainly  is  within  reason.

signals  so  that  you  can  see  and  hear 
just  how  you  make  your  signals.  {See

HAM-ADS 


(1)  Advertising  sh?ll  pertain  to  radio  and  shall  be  of 
nature  of  interest  to  radio  amarteurs  or  expeimenters  in 
their  pursuit  of  the  art. 

(2)  No  display  of  any  character  will  be  accepted,  nor  can 
any  special  typographical  arrangement,  such  as  all  or  part 
capital  letters  be  used  which  would  tend  to  make  one  adver- 
tisement stand  out  from  the  others.  No  Box  Reply  Service 
can  be  maintained  in  these  columns. 

(3)  The  Ham-Ad  rate  is  30^  per  word,  except  as  noted  in 
paragraph  (6)  below. 

(4)  Remittance  in  full  must  accompany  copy.  No 
cash  or  contract  discount  or  agency  commission  will 
be  allowed. 

(5)  Closing  date  for  Ham-Ads  is  the  20th  of  the  second 
month  preceding  publication  date. 

(6)  A  special  rate  of  li  per  word  will  apply  to  adver- 
tising which,  in  our  judgment,  is  obviously  non- 
commercial in  nature,  and  is  placed  and  signed  by  a 
member  of  the  American  Radio  Relay  League.  Thus, 
advertising  of  bona  fide  surplus  equipment  owned,  used  and 
for  sal?  by  an  individual  or  apparatus  offered  for  exchange  or 
advertising  inquiring  for  special  equipment,  if  by  a  member 
of  the  American  Radio  Relay  League  take  the  70  rate.  An 
attempt  to  deal  in  apparatus  in  quantity  for  profit,  even 
if  by  an  individual,  is  commercial  and  all  advertising  by 
him  takes  the  300  rate.  Provisions  of  paragraphs  (1),  (2) 
and  (5),  apply  to  all  advertising  in  this  column  regardless 
of  which  rate  may  apply.  To  expedite  handling  of  your 
copy  please  state  whether  you  are  member  of  ARRL. 

(7)  Because  error  is  more  easily  avoided,  it  is  re- 
quested signature  and  address  be  printed  plainly. 
Typewritten  copy  preferred,  but  handwritten  signa- 
ture must  accompany  all  authorized  insertions. 

t8)  No  advertiser  may  use  more  than  100  words  in  any 
one  issue  nor  more  than  one  ad  in  one  issue. 


Having  made  no  investigation  of  the  advertisers  in  the  classified 
columns,  the  publishers  of  QST  are  unable  to  vouch  for  their 
integrity  or  for  the  grade  or  character  of  the  products  or  services 
advertised.

^e4€  (facci   QRK 

THIS  little  quiz  is  based  on  articles 
appearing  in  QSTiox  March.  How 
much  do  you  remember  from  the  issue 
of  two  months  ago? 

1.  What  is  the  least  noisy  vacuum 
tube  amplifier? 

2.  What  benefit  is  gained  by  "fan- 
ning" elements  of  a  beam  antenna? 

3.  Multivibrators  are  usually  used 
to  divide  the  frequency  of  a  crystal 
oscillator  by  a  factor  of  not  more 
than . 

4.  What  adjustments  at  the  transmit- 
ter will  affect  the  s.w.r.  in  the  trans- 
mission line? 

5.  What  bill  of  interest  to  amateurs 
is  pending  in  Congress? 

How  you  scored  doesn't  matter  too 
much.  The  important  question  for  any 
active  amateur  is  "What  magazine 
covers  the  whole  of  amateur  radio — 
regulatory  matters,  operating  activi- 
ties, and  first  class  technical  arti- 
cles?" .  .  .  and  the  answer  is:  QST. 
Is  it  dehvered  to  your  door  every 
month?

90900  Series 
Cathode  Ray  Oscilloscopes 

The  No.  90902,  No.  90903  and  No.  90905  Rack 
Panel  Oscilloscopes,  for  Iwo,  three  and  five  inch 
lubes,  respectively,  are  inexpensive  batic  units 
comprising  power  supply,  brilliancy  and  center- 
ing controls,  safety  features,  magnetic  shielding, 
switches,  etc.  As  a  transmitter  monitor,  no  addi- 
tional equipment  or  accessories  are  required.  The 
well-known  trapezoidal  monitoring  patterns  are 
secured  by  feeding  modulated  carrier  voltage 
from  a  pickup  loop  directly  to  vertical  plates  of 
the  cathode  ray  tube  and  audio  modulating  volt- 
age to  horizontal  plates.  By  the  addition  of  such 
units  as  sweeps,  pulse  generators,  amplifiers, 
servo  sweeps,  etc.,  all  of  which  can  be  con- 
veniently and  neatly  constructed  on  companion 
rack  panels,  the  original  basic  'scope  unit  may  be 
expanded  to  serve  any  conceivable  industrial  or 
laboratory  application.

In  the  Heathkit  DX-100,  a  single  RCA-5763  beam  power 
tube  drives  two  RCA-6146  beam  power  types  in  parallel  in 
the  final— an  ideal  combination  that  is  capable  of  delivering 
a  "healthy"  signal  at  a  very  modest  cost. 

Here's  ONE  basic  reason  — among  many  — why  amateur 
and  professional  designers  prefer  RCA  Tubes. 

RCA  High-Perveance  tubes  deliver  high  power  output  — 
at  loiver  plate  voltages.  For  you  this  means:  (1)  lower-volt- 
age filter  capacitors, (2)  lower-voltage  tank  circuits,  (3)  more 
reasonable  values  of  pi-network  components,  (4)  fewer 
problems  with  rf  and  dc  insulation. 

RCA  high-perveance  power  tubes— both  beam  and  triode 
types  — are  available  at  your  RCA  Tube  Distributor.  For

•  Right:  the  "why"  of  G-E  "Operation  Snow  White".  Unretouched  micro- 
photograph  of  tube  grid,  shows  a  strand  of  lint  which  can  easily  cause 
an  inter-electrode  short-circuit.  Dust  particles  have  similar  effect. 


•  Glass-paneled  hoods  for  General  Klectiic 
5-Star  Tube  assembly  and  microscope  inspec- 
tion, assure  working  conditions  of  optimum 
cleanliness.  Employees  wear  rubber  finger  cots, 


to  avoid  contaminating  tube  parts  with  dirt  or 
moisture.  The  entire  "Snow  White"  area  is  air- 
conditioned  and  pressurized,  and  all  garments 
are  made  of  lint-free  Nylon  and  Dacron. 


G-E  "Operation  Snow  White"  furtlier  increases 
5-StarTube  higli  reliability! 


Inoperatives  among  5-Star  Tubes  have 
been  cut  two-thirds  by  measures  G.E. 
has  taken  to  provide  Hnt-free,  dust-free 
assembly  and  inspection.  100%  5-Star 
factory  tests  prove  this  gain  in  built-i7i 
tube  dependabiUty. 

Most  tube  inoperatives  are  the  result 
of  intermittent  "shorts"  from  lint  and 
dust.  G-E  "Operation  Snow  White",  by 
means  of  pressurized,  filtered,  and  de- 
humidified air,  plus  numerous  other 
steps  to  accent  working  cleanliness,  cuts 
down  on  short-circuits  at  the  source. 
Result:  5-Star  Tubes  are  the  most  trust- 


worthy types  that  you  can  install! 

Use  them  in  civil-defense  work,  where 
dependable  communications  are  a 
"must"!  Specially  designed,  built,  and 
tested,  they're  your  foremost  protection 
against  rig  and  receiver  failures.

75A-4 


Advanced  design  features  of  Collins  new 
75A-4  receiver  provide  the  greatest  ease  in 
SSB,  AM,  or  CW  operation  ever  offered  to 
the  amateur.  Proven  circuitry  of  the  earlier 
75 A  receivers  such  as  crystal  controlled  first 
injection  oscillator,  hermetically  sealed  VFO 
and  mechanically  filtered  IF  selectivity  are 
retained. 


PASSBAND  TUNING 


The  receiver  BFO  is  mechanically  ganged  and 
tracked  with  the  main  tuning  dial.  Once  a 
SSSC  signal  is  tuned  in,  it  can  be  moved  around 
in  the  passband  to  tune  out  interfering  signals, 
and  it  also  allows  selection  of  either  sideband 
for  SSB  operation.  In  CW  reception  the  desired 
signal  can  be  moved  around  in  the  passband 
without  changing  the  received  beat  note,  and  at 
the  same  time,  interfering  signals  can  be  pushed 
off  the  edge  of  the  steep  sided  mechanically 
filtered  passband. 

REJECTION  TUNING 

A  combination  "Q"  multiplier  and  bridged-T 
rejection  notch  filter,  are  used.  The  filter  has 
a  deep,  narrow  notch  and  is  effective  anywhere 
in  the  passband.  Conventional  crystal  filters 
become  inoperative  at  frequencies  several 
hundred  cycles  on  either  side  of  the  resonant 
frequency.  The  "T"  filter  does  not  distort  the 
IF  passband  seriously  as  does  the  crystal  filter. 
Heterodynes  are  effectively  eliminated  with  little 
loss  of  intelligibility. 


AVC 

A  fast  attack,  slow  release  AVC  system  is  em- 
ployed in  the  75A-4.  It  will  respond  to  the 
first  few  cycles  of  a  sideband  transmission  and 
does  not  require  the  presence  of  a  carrier  for 
operation.  Fast  and  slow  release  times  are 
selectable  by  means  of  a  panel  mounted  con- 
trol. The  fast  is  used  normally  for  AM  recep- 
tion. The  slow  is  used  during  sideband  and  CW 
reception  and  prevents  the  receiver  from  open- 
ing up  during  words  and  characters. 

SEPARATE 

AM  AND  SSB  DETECTORS 

Separate  detectors  are  used  for  double  or  single 
sideband  signals.  The  single  sideband  detector 
is  a  mixer  type,  which  generates  much  less  dis- 
tortion than  a  conventional  diode  detector  on 
a  SSSC  signal.  A  diode  detector  is  used  for 
conventional  double  sideband  signals.

^^^  AMERICAN 
RADIO  RELAY 
LEAGUE,  INC., 

is  a  noncommercial  association  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
advancement  of  the  radio  art  and  of  the  public  welfare,  for  the 
representation  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  Incorporated  association  without  capital  stock,  chartered 
under  the  laws  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu- 
facture, sale  or  rental  of  radio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amateur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited.  A  bona  fide 
interest  in  amateur  radio  is  the  only  essential  qualification;  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  gronted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us... 


PUBLIC  RELATIONS 

The  instances  are  fortunately  rare,  but  every 
now  and  then  an  item  in  a  newspaper  will 
carry  an  account  of  amateur  radio  which  can 
be  classified  as  uncomplimentary.  The  subject 
is  usually  amateur  interference.  Occasionally 
the  item  is  directly  antagonistic;  more  often 
the  disparagement  is  implied,  or  convej'ed  by 
an  inaccurate  headline. 

In  some  of  these  few  cases  amateurs  will 
write  the  League  asking  that  a  retiaction  be 
demanded.  In  our  experience,  this  is  entirely 
the  wrong  approach,  for  two  reasons:  Too 
much  time  is  wasted  (any  effective  action  must 
be  immediate) ;  and  generally  speaking  the 
editor  is  more  impressed  with  a  protest  from 
his  local  readers  than  one  from  a  distant 
organization.  Usually,  an  alert  local  ham  or 
club  will  take  immediate  action  by  contacting 
the  paper  or  writing  a  letter  to  the  editor  in 
an  attempt  to  obtain  clarification  and  set  the 
record  straight.  While  this  is  the  preferable 
procedure,  it  still  has  the  disadvantage  of 
again  mentioning  interference  and  amateui-s 
in  the  same  breath,  and  thus  tends  to  accentu- 
ate the  association  of  ideas. 

There's  a  much  better  basic  approach. 

WTiat  is  needed  is  full,  complete  and  accurate 
accounts  of  all  other  amateur  doings,  so  that 
any  localized  interference  problems  will  seem 
minor  in  comjiarison  to  the  good  that  can  be 
and  is  being  accomphshed  by  pubhc-spirited 
hams.  In  other  words,  a  good  long-range  public 
relations  program.  To  paraphrase  the  song 
title,  j^ou  eliminate  or  neutralize  the  negative 
by  accentuating  the  positive. 

Naturally,  an}'  emergency  activities  of  ama- 
teurs should  be  promptly  and  fully  reported 
to  the  newspapers  and  radio  stations.  But  in 
any  one  community  emergencies  are  few  and 
far  between.  You  can't  create  a  disaster,  but 
you  can  be  alert  to  participation  in  civic 
projects,  or  to  initiation  of  some  of  your  own, 
to  maintain  and  improve  the  local  standing  of 
your  amateur  group.  We'd  like  to  mention 
here  several  such  special  projects,  simply  to 
suggest  angles  which  you  might  use. 

"Must"  reading  for  those  concerned  witli 
the  state  of  our  public  relations  is  the  article 
in  November  QST,  describing  Marj'land  Ama- 
teur Radio  Week  activities  of  the  Baltimore 
Amateur  Radio  Club.  It's  full  of  project  ideas. 


A  number  of  clubs  have  cooperated  in  fund- 
raising  drives.  One  helped  out  in  an  aU-night 
Telethon  on  behalf  of  the  March  of  Dimes. 
Persons  wishing  to  contribute  called  the  TV 
station,  whereupon  an  amateur  net  control 
installation  directed  a  mobile  to  the  address, 
where  civic  club  members  performed  the  leg- 
work  of  actually  calling  on  the  donors.  Another 
amateur  club  undertook  a  similar  project  in 
a  cerebral  palsy  drive,  enriching  it  to  the  tune 
of  $50,000  —  and  doing  themselves  a  world 
of  good  in  public  relations. 

In  a  city  famous  for  its  huge  parades,  hams 
offered  their  services  to  the  grand  marshal. 
The  mai-shal  reluctantly  accepted,  and  ended 
up  immenseh'  pleased  —  the  parade  started  on 
schedule  for  the  first  time  in  the  city's  history! 
Needless  to  saj',  hams  are  now  a  fixture  when- 
ever they  "strike  up  the  band." 

But  3'^ou  don't  need  to  wait  for  fund  drives 
or  parades;  except  in  the  larger  cities,  a  great 
many  amateur  occurrences  are  considered 
newsworthy.  The  local  club  receiving  its  char- 
ter of  ARRL  affiliation;  a  local  amateur  mak- 
ing DXCC;  an  emergency  coordinator  being 
appointed ;  participation  by  the  club  members 
in  a  contest,  Field  Day,  or  hamfest;  dehvery 
of  a  message  from  a  serviceman  in  Alaska  to 
his  mother  —  all  these  and  a  host  of  other  ac- 
tivities, however  common  they  seem  to  us,  can 
mean  an  inch  or  two  in  the  Daily  Bugle  or  30 
seconds  on  "The  Voice  of  Podunk." 

What  else?  Well,  is  your  PTA  putting  on 
a  hobby  show?  Be  in  it!  Kiwanis  looking  for 
a  speaker?  Volunteer!  Does  your  company 
have  a  "house  organ"?  Its  editor  would 
probably  be  dehghted  to  have  a  feature  story 
un  the  hams  in  the  company. 

Pubhcity  helps  are  available  at  League 
Headquarters  to  make  it  easier  for  you,  too. 
A  sample  speech,  interview,  radio  broadcast 
program,  and  TVI  script  with  slides  are  avail- 
able. So  are  reprints  of  outstanding  amateur 
stories,  which  have  appeared  in  nationally- 
known  magazines,  to  explain  our  hobby  to 
interested  BCLs. 

Good  public  relations  are  important  to 
nearly  every  society,  corporation,  or  charity, 
but  especially  important  to  us  —  our  ver\' 
licenses  depend  on  our  activities  being  "in  the 
public  interest,  convenience,  or  necessity."  We 
must  leave  no  doubt  in  the  minds  of  the  public 
that  we  meet  this  requirement.

A  Four-Band  S.S.B.  VFO 

Single  Fundamental  Range  for  Use  with  Conversion- 
Type  S.S.B.  Exciters 

BY  GORDON  LAUDER,*  W9PVD 


MOST  of  the  VFOs  used  in  s.s.b.  work  with  the 
Central  Electronics  exciters  and  others 
using  a  9-Mc.  master  oscillator  cover  one, 
or  at  the  most,  two  bands:  75  meters,  or  75  and 
20  meters.  This  is  because  the  same  5-Mc.  in- 
jection frequency  can  be  used  in  the  mixer  stage 
for  both  these  bands,  but  not  for  others.  However, 
the  injection  frequencies  for  40-  and  160-meter 
operation  are  harmonically  related  to  this  same 
5-Mc.  injection  frequency.  The  beautiful  part  of 
this  is  that  the  oscillator  can  always  be  calibrated 
against  the  5-Mc.  signal  of  WWV.  Thus  a  VFO 
with  a  fundamental  tuning  range  of  5.0  to  5.5 
Mc,  plus  a  bandswatched  buffer/multiplier  stage, 
will  furnish  outputs  on  all  four  bands. 

Using  two  miniature  tubes  and  slug-tuned 
coils,  a  complete  unit  can  be  built  horizontally  on 
a  3J^-inch  rack  panel,  as  indicated  by  the  accom- 
panying photographs  of  the  one  used  at  W9PVD. 
The  tuning  is  done  with  a  National  tj-pe  MCN 
dial  which  has  been  equipped  with  a  National 
type  HRT  knob  for  ease  of  tuning. 

The  circuit  uses  two  6AK6  tubes,  one  as  an 
electron-coupled  oscillator  and  the  other  as  a 
buffer/multiplier  stage.  The  plate  coils  of  the 
buffer/multiplier  stage  are  shorted  out  electri- 
call}',  when  not  in  use,  bj-  a  Centralab  switch  that 
connects  all  unused  contacts,  thus  connecting  B- 
plus  to  both  sides  of  unused  coils.  Shorting  the 
coils  allows  mounting  them  in  close  proximity. 
All  that  is  necessar}-  is  to  wire  B-plus  voltage  to 
anj'  unused  contact  on  the  switch. 

An  0B2  VR  tube  is  used  to  stabihze  plate  and 
screen  voltages  of  both  tubes.  Each  stage  uses 
10  ma.  of  cathode  current.  The  Central  Elec- 
tronics exciters  furnish  300  volts  at  25  ma. 
through  the  accessory-  socket  in  the  rear.  The

•  No  doubt  there  would  be  more  s.s.b. 
activity  on  7  and  1.8  IMc.  if  it  were  not 
generally  thought  that  a  separate  VFO 
is  needed.  Here's  how  to  make  one  ^TO 
unit  serve  for  both  the  popular  4/14-Mc. 
combination  and  the  above  two  bands  as 
well. 


0B2  dropping  resistor  is  adjusted  until  a  current 
of  23  ma.  is  drawn  with  the  6AK6s  out  of  their 
sockets.  This  allows  a  margin  of  insurance  against 
loss  of  ignition  in  the  VR  tube.  At  these  current 
and  voltage  settings,  sufficient  VFO  injection  is 
developed  to  give  stable  operation  on  all  four 
bands. 

Con  struc  Hon 

The  author's  VFO  was  built  on  a  homemade 
chassis.  Room  was  reserved  on  the  left  side  of 
the  panel  for  mounting  a  2-inch  'scope  monitor, 
as  described  in  the  1954  ARRL  Handbook. 

The  best  size  in  commercially  available  chassis 
would  be  the  5  X  10  X  3-inch  with  bottom  plate. 
The  dimensions  of  the  chassis  at  W9PVI)  are 
5X7X3  inches.  The  chassis  is  mounted  with 
the  top  down  and  even  with  the  bottom  of  the 
panel,  to  allow  clearance  for  the  bottom  of  the 
National  MCN  dial  mechanism.  The  dial  is 
mounted  with  the  top  flush  with  the  top  of 
the  panel.  The  tuning  condenser,  Ci,  is  mounted 
on  an  aluminum  bracket  so  as  to  line  up  with 
the  dial  drive. 

The  switch  Si  is  mounted  on  another  bracket 
with  the  end  of  the  2-inch  shaft  projecting 
through  a  3/8-inch  hole  in  the  panel  to  allow 
mounting  the  knob.  This  switch  is  mounted  to  be 


The  four-band  s.s.b.  VFO  fits 
readily  on  a  3J4-inch  relay  rack 
panel.  By  choosing  the  proper  funda- 
mental tuning  range  and  using  ap- 
propriate harmonics,  four  bands  can 
be  covered  vtith  exciters  using  a 
9-Mc.  s.s.b.  generating  frequency.

mounted  in  a  roughly  triangular  grouping  to 
give  minimum  lead  length  to  Si.  L5  should  be 
positioned  for  the  shortest  leads  as  it  is  the 
highest-frequency  coil.  After  these  come  F3  and 
the  jack,  Ji.  A  6-prong  Jones  chassis- type  male 
connector  was  used  for  Ji  because  it  was  avail- 
able in  the  junk  box.  However,  any  male  connec- 
tor having  5  or  more  prongs  will  do  the  job.

The  two  stages  are  shielded  to  reduce  the  pos- 
sibility of  feed-back  when  the  buffer/multiplier 
is  operated  at  the  oscillator  frequency.  The 
coupling  capacitor,  Ce,  is  mounted  inside  a  J^- 
inch  rubber  grommet,  both  for  mechanical  sta- 
bility and  insulation. 

Only  two  of  the  coils,  Li  and  L5,  need  to  be 
wound  by  the  constructor.  The  total  number  of 
turns  for  Li  was  wound  on  the  XR-50  coil  form, 
then  5H  turns  were  backed  off  before  cutting 
and  soldering  to  the  ground  end.  The  enamel  is 
carefully  scraped  off  with  a  knife,  and  the  tap  is 
made  by  wrapping  the  bared  wire  around  a 
small  diameter  nail  and  then  twisting  once  to

any  'scope,  providing  necessary  space  for  mount- 
ing the  parts  can  be  found.  In  this  case,  very  little 
space  was  available  immediately  behind  the  front 
panel,  so  two  small  subchassis  were  fabricated 
and  set  back  on  the  main  chassis  with  extension 
shafts  run  through  panel  bushings  for  the  control 
knobs.  As  shown  in  the  front-view  photograph, 
the  added  rows  of  controls  are  placed  midway 
between  the  existing  controls  with  the  voltage 
calibrator  on  the  left  side,  and  the  Z-axis  am- 
plifier on  the  right. 

Voltage  Calibrator 

The  voltage  calibrator  (Fig.  1)  consists  of  a 
fiee-running  symmetrical  multivibrator  (Fi) 
operating  at  approximately  1500  c.p.s.  Its  output 
is  taken  off  the  plate  of  Fib  through  Ci  to  the  top 
(»!'  the  diode  load  resistor,  Ri.  F2A  is  connected  as 
a  diode  and  functions  as  a  clipper  to  square  the 
waveshape.  The  plate  of  V^a  is  direct-coupled  to 
the  grid  of  cathode  follower,  ^20,  and  the  output

peak-to-peak  voltage  in  each  position  of  Si,  as 
indicated,  may  be  taken  from  the  arm  of  the 
switch  and  attenuated  through  the  gain-control 
potentiometer  Rn. 

Potentiometer  Rz  in  the  voltage  divider, 
R^RzRi,  controls  the  bias  on  the  cathode  of  F2A 
which,  in  turn,  controls  the  output  voltage  of  the 
calibrator.  Output  voltage  is  taken  from  the  arm 
of  Rn  to  the  calibrating  position  of  (S2A  for  com- 
parison with  the  signal  being  measured. 

Z-Axis  Amplifier 

The  first  tube  in  the  Z-axis  amplifier  (Fig.  2) 
is  a  12AU7  duo-triode  acting  as  a  phase  inverter. 
The  cathodes  of  both  sections  are  tied  together 
using  the  same  cathode  resistor,  Ru.  The  second 
section  operates  as  a  grounded-grid  amplifier. 
Signals  from  the  plate  of  each  section  to  the 
ends  of  the  center-tapped  potentiometer  R\f,  are 
equal  and  180  degrees  out  of  the  phase.  This 
potentiometer  must  be  linear,  with  25,000  ohms 


each  side  of  center  tap.  The  tube  gives  a  gain  of 
four  for  each  phase. 

The  signal  is  then  taken  from  the  arm  of 
the  gain-and-phase-control  potentiometer,  Ri^,, 
through  Ci  to  the  input  grid  of  F4.  F4  is  a  triode 
voltage  amplifier  with  a  gain  of  12,  thereby  giving 
a  total  gain  of  48  through  the  amplifier  in  either 
a  positive  or  negative  direction.  From  the  plate 
of  F4,  the  signal  is  passed  on  to  the  top  of  Ry^ 
and  through  C3  to  the  grid  of  the  cathode-ray 
tube.  Positive  signals  at  this  point  brighten  the 
trace,  while  negative  signals  bias  the  tube  toward 
cut-off.  Cz  must  be  a  high-voltage  capacitor  to 
withstand  the  negative  d.c.  voltage  on  the  grid

The  pulse  for  blanking  is  taken  from  the 
oscilloscope  horizontal-sweep  oscillator  and  dif- 
ferentiated through  C4  and  Rn.  During  the  slow 
rise  time  of  the  sawtooth  sweep,  no  voltage  is 
developed  but  the  rapid  fall  in  voltage  at  the  end 
of  the  sawtooth  develops  a  pulse  at  the  junction

The  size  and  width  of  this  pulse  is  adjusted  by

grid  of  the  cathode-ray  tube,  thus  biasing  the 
grid  to  cut-off,  and  blanking  during  the 
retrace. 

Con  struc  Hon 

The  material  used  in  the  construction 
of  the  two  subchassis  is  0.026-inch  copper 
sheet,  since  it  is  easily  worked.  They 
were  cut  out,  drilled  and  bent  to  shape  in 
a  small  vise,  as  shown  in  Figs.  3A  and  3B. 

A  photograph  shows  the  voltage- 
calibrator  chassis  with  the  components 
mounted  and  wired.  The  calibration  po- 
tentiometer, i^ii,  is  shown  mounted  on 
the  lip  of  the  chassis,  with  the  multiplier 
switch  (»Si)  just  below.  The  Z-axis  am- 
plifier chassis  is  bent  in  the  opposite 
direction,  with  the  gain-and-phase  po- 
tentiometer, R\-a,  mounted  on  the  lip, 
and  the  selector  switch  Sz  below.  These 
four  controls  are  reached  with  e.xtension 
shafts  through  panel  bushings,  the  re- 
maining controls  being  mounted  on  the 
front  panel. 

In  the  photograph  of  the  voltage  cali- 
brator, the  potentiometer  shaft,  R^,  may 
be  seen  extending  through  the  chassis 
where  it  is  available  after  assembly  for 
adjustment  of  the  voltage-calibrator 
output.  The  potentiometer  is  mounted 
between  the  tubes  on  the  top  side  of  the 
chassis,  its  leads  being  fed  through  a 
small  grommet  to  the  underside. 

Both  amplifiers  should  be  completely 
wired  according  the  schematics,  leaving 
signal,  B  -|-  and  heater  leads  long  enough 
to  reach  their  connections.  Wiring  is  not 
at  all  critical  and  point-to-point  wiring 
was  employed  to  conserve  space. 

The  holes  in  the  front  for  the  added 


controls  are  all  ^-inch  diameter.  The  hole  for  the 
shaft  of  the  voltage-calibrator  gain  potentiome- 
ter, Rn,  is  centered  234  inches  above  the  main 
chassis,  and  midway  between  the  oscilloscope 
vertical-gain  and  frequency-selector  controls.  The 
hole  for  the  shaft  of  the  multiplier  sv^itch.  Si,  is 
1 3^  inches  below.

The  voltage-calibrator  switch,  S2,  is  mounted 
on  the  panel  in  the  most  available  position  be- 
tween the  oscilloscope  vertical-input  attenuator 
switch  and  the  vernier  frequency  control. 

The  hole  for  the  shaft  of  the  Z-axis  gain  and 
phase  control,  Ris,  is  centered  2}4  inches  above 
the  main  chassis,  and  midway  between  the  fre- 
quency-selector switch  and  the  horizontal  gain 
control.  The  hole  for  the  shaft  of  the  selector 
switch,  S3,  is  13^  inches  below.  The  blank-phase 
potentiometer,  R\7,  is  mounted  on  the  panel 
midway  between  the  frequency-vernier  and 
synchronizing  controls.  The  Z-axis  input  jack  is 
located  just  above  the  horizontal  input  switch. 

The  placement  of  the  two  subchassis,  with 
their  extension  shafts  through  the  panel  bushings, 
is  shown  in  the  rear-view  photo  of  the  'scope. 
The  Z-axis  amplifier  chassis  is  on  the  left  side  of 
the  photograph,  just  behind  the  'scope  horizontal- 
sweep-amplifier  tube  (6J5)  and  the  voltage- 
calibrator  chassis  is  on  the  right  in  front  of  the 
power-supply  rectifier  tubes. 

The  Z-axis  amplifier  draws  only  8  ma.  in 
operation,  and  the  voltage-calibrator  requires 
10  ma.,  so  they  may  be  operated  from  the  os- 
cilloscope power  supply,  as  shown  in  Fig.  1.  The 
power-supply  output  voltage  is  340.  This  poten- 
tial is  dropped  to  240  volts  through  Ru  for  the 
voltage  calibrator,  and  to  250  volts  through 
Ri3  for  the  Z-axis  amplifier.  In  the  calibrato 
position,  SiB  puts  plate  voltage  on  the  calibrator, 
and  SsB  has  the  same  function  for  the  Z-axis 
amplifier.  It  is  necessary  to  provide  another 
filament  source  for  the  tubes,  so  a  small  fila- 
ment transformer,  Ti  in  Fig.  3,  is  mountc^l 
alongside  the  power  transformer,  under  the  main 
chassis. 

After  the  units  were  installed  and  the  wiring 
completed,  switch  positions  on  the  front  panel 
were  labeled  with  decals  as  shown.  The  voltago- 
calibrator  multiplier  switch  shows  maximum 
output  voltages  of  50,  25,  10,  5,  1  and  0.1.  These 
voltages  may  be  attenuated  at  each  position 
with  the  gain  potentiometer,  Rn,  which  is  cali- 
brated in  tenths  on  the  front  panel. 

The  only  adjustment  necessary  after  comple- 
tion is  to  set  the  output  level  of  the  voltage 
calibrator.  This  calibration  is  in  peak-to-peak 
volts  which  is  equal  to  2.88  r.m.s.  voltage.  Divid- 
ing the  maximum  output  voltage  of  50  by  2.88 
is  equal  to  17.4  volts  r.m.s.  Turn  on  the  oscillo- 
scope, put  »Si  in  the  50-volt  position,  and  turn  up 
the  gain  pot,  Rn,  to  ma.ximum  output.  A  square 
wave  should  appear  on  the  screen,  as  shown  in 
Fig.  4  (left),  if  the  horizontal  sweep  is  at  a  slow- 
rate.  However,  if  the  sweep  speed  is  increased, 
an  image  such  as  Fig.  4  (right)  will  appear.  Con- 
nect an  a.c.  voltmeter  to  Pin  8  of  V2  and  adjust 
potentiometer  R3  so  the  r.m.s.  output  voltage 
reads  17.4  volts.  The  calibrator  is  now  ready  for 
operation. 

Turn  (82  to  the  signal  position,  and  feed  a  sine 
wave  into  the  'scope  input.  Adjust  the  trace  to 
any  convenient  height  between  selected  lines  on 
the  screen  mask.  Turn  S2  to  the  calibrate  position 
and  adjust  the  multiplier  switch.  Si,  and  gain  pot, 


Rn,  till  the  square  wave  on  the  screen  is  at  the 
same  height  between  the  previously  selected  lines. 
The  sine-wave  peak-to-peak  voltage  may  now 
be  read  by  noting  the  position  of  the  multiplier 
switch  and  the  percentage  of  the  gain  pot  used. 
For  example:  If  the  multiplier  switch  reads  5 
and  the  gain  pot  7,  there  would  be  an  indicated 
voltage  of  0.7  X  5,  or  3.5  volts  peak-to-peak  or, 
dividing  by  2.88,  1.22  volts  r.m.s. 

Turn  S2  to  the  signal  position,  put  the  sine 
wave  back  on  the  'scope  screen  and  turn  up  the 
intensity  control  so  both  the  sine  wave  and 
retrace  are  visible  as  at  5  (left).  Turn  S3  to  the 
blanking  position,  advance  the  Z-axis  gain  con- 
trol, Riz,  to  its  positive  position,  and  advance  the 
blanking-phase  pot,  Rn,  until  the  retrace  just 
disappears  as  at  5  (right).  The  small  bit  of  retrace 
left  on  5  (right)  would  be  eliminated  by  increasing 
the  gain  of  the  blanking  control.  At  low  frequen- 
cies most  of  the  resistance  in  T^iv  will  be  needed 
for  blanking,  but  this  becomes  successiveh^  less 
as  the  frequency  (speed)  is  increased. 

Z-Axis  Amplifier 

Set  the  Z-axis  pot,  72i6,  to  zero  (midposition). 
Turn  S3  to  the  Z-amphfier  position.  "Take  the 
sine-wave  injection  out  of  the  vertical  input  antl 
put  a  sine-wave  signal  of  approximately  1  volt, 
1000  c.p.8.  into  the  Z-axis  input  jack.  Set  the 
'scope  horizontal  sweep  at  approximately  100 
c.p.s.,  and  advance  the  Z-axis  gain  control  toward 
either  positive  or  negative  polarity,  readjusting 
the  sweep  rate  at  the  same  time  until  the  baseline 
becomes  a  series  of  dashes.  The  number  of  dashes 
will  show  the  frequency  ratio  of  the  sine-wave 
input  to  the  sweep  frequency  and  is  a  handy  way 
to  check  frequency  rate. 

Turn  the  Z-axis  pot  to  zero  position.  Leave  the 
sine-wave  signal  on  the  Z-axis  input,  and  inject 
the  same  signal  into  the  vertical  input  of  the 
'scope,  placing  several  cycles  on  the  tube  screen. 
Turn  down  the  'scope  intensity  control  until  the 
trace  disappears,  and  advance  the  Z-amplifier 
gain  control  toward  positive.  The  trace  should 
appear  similar  to  Fig.  6  as  the  cathode-raj'-tube 
grid  is  driven  positive  from  cut-off  by  the  positive 
part  of  the  Z-axis  signal. 

Fig.  6  (left)  shows  a  series  of  two-microsecond 
positive  pulses  which  were  barely  visible  on  the 
screen  before  brightening  with  intensity  modula- 
tion, accomplished  by  injecting  the  signal  into 
both  vertical-input  and  Z-axis  terminals.  Fig.  7 
shows  one  cycle  of  sine  wave  into  the  'scope  verti- 
cal input  with  four  cycles  of  square-wave  input 
to  the  Z  axis,  and  is  another  method  of  checking 
frequency  rate. 

Fig.  8  (left)  shows  the  horizontal  baseline  with 
a  marker-signal  input  to  the  Z-axis  amplifier. 
The  Z-axis  gain  control  is  advanced  toward 
positive  phase,  giving  a  bright  marker  on  the 
baseline.  Turning  the  gain  control  toward  nega- 
tive phase  puts  a  hole  in  the  baseline,  as  at  8 
(right).

of  the  2-axis  amplifier  may  be  found  in  Rider's 
Encyclopedia  on  Cathode-Ray  Oscilloscopes.

Band-Scanning  —  The  Easy  Way 

A  Simple  Means  of  Automatic  Receiver  Tuning 
BY  K.  R.  JONES.*  W70SL 


•  This  simple  gadget  should  appeal  to 
many,  both  as  a  novelty  and  as  a  utility. 
It  lets  you  sit  back  and  hear  the  sigs  go 
by.  The  lazy  man  will  find  it  just  the 
thing  for  watching  for  band  openings. 
It  requires  no  alterations  of  the  receiver, 
and  can  be  connected  or  disconnected 
in  a  second  or  two. 


HAVE  you  ever  spent  valuable  time  tuning 
across  the  10-,  15-,  or  20-meter  bands 
without  finding  a  single  signal?  Then  you 
must  have  wished  for  an  easier  way  to  catch  the 
band  openings  which  are  so  rare  in  this  period 
of  the  sunspot  cycle.  Perhaps  what  you  need  is 
an  automatic  tuner  to  operate  the  receiver  while 
you  sit  in  an  easy  chair  reading  QST. 

Of  course,  any  well-equipped  machine  shop 
could  attach  an  assortment  of  gears,  cranks 
and  motors  to  your  receiver  that  would  do  the 
job,  but  most  hams  would  prefer  to  get  the 
results  without  altering  their  receivers.  It  can 
be  done.  Most  of  the  needed  parts  may  even  be 
in  your  junk  box  now. 

The  theory  is  easy.  All  you  have  to  do  is  vary 
the  tuning  of  the  receiver's  high-frequency  os- 
cillator at  a  slow  rate.  A  motor-driven  capacitor 
clipped  on  in  parallel  with  the  h.f.  oscillator 
tuning  capacitor  will  do  the  trick,  and  the  only 
disadvantage  is  a  temporary  shift  in  dial  calibra- 
tion during  the  time  the  motor-driven  scanning 
capacitor  is  in  use.  Theoretically,  the  r.f.  and 
mixer  tuning  should  also  be  varied,  but  most 
receivers  in  the  lower-price  brackets  have  only 
one  r.f.  stage  and  the  front-end  passband  is  so 
broad  that  little  loss  in  gain  can  be  noticed  over 
a  small  frequency  range  when  only  the  oscillator 
is  tuned. 

The  unit  illustrated  was  assembled  for  use 
with  an  NC-57  receiver.  An  old  electric  clock 
motor  was  used  as  the  base  and  a  scrap  of  alumi- 
num was  bent  to  form  a  mounting  for  a  ball- 
bearing butterfly  capacitor,  as  shown  in  the 
photograph.  The  shaft  coupling  was  made  from 
a  small  block  of  plastic.  An  APC-type  padding 
capacitor  was  fastened  on  top  and  connected  in 
series  with  the  butterfly  capacitor  to  vary  the 
bandwidth  scanned.  The  whole  unit  is  small 
enough  to  fit  inside  the  receiver  near  the  tuning- 
capacitor  gang. 

Although  the  unit  scans  only  about  200  kc. 
on  the  v.h.f.  amateur  bands,  it  has  proved  very 
satisfactory  in  detecting  band  openings.  It  has 

♦  627  Fifth  Ave.,  Salt  Lake  City,  Utah. 


also  been  very  interesting  to  operate  it  on  bands 
where  there  is  plenty  of  activity.  At  a  rate  of 
two  scannings  (one  complete  revolution  of  the 
capacitor  shaft)  per  minute,  the  tuning  is  covered 
so  slowly  that  several  words  can  be  heard  from 
each  station  as  it  is  passed,  and  familiar  voices 
can  be  recognized. 

Con  struc  Hon 

Specifications  are  listed  with  the  schematic, 
but  as  identical  parts  may  not  be  available, 
several  points  in  construction  should  be  stressed. 
First,    and    most    important,    is    keeping   stray

capacitance  at  a  minimum  since  this  will  have  a 
considerable  effect  on  how  far  the  r.f.  stage  must 
be  detimed  from  normal. 

Second,  the  butterfly  capacitor  must  turn 
very  easily.  The  ball-bearing  type  shown  is 
ideal,  but  with  some  ingenuity  in  loosening  and 
lubricating  the  bearings,  a  plain-bearing  type 
might  be  satisfactory.  A  capacitor  with  a  stop 
cannot  be  used,  of  course. 

Third,  the  capacitor  shaft  should  be  very 
carefully  aligned  with  the  motor  shaft  to  prevent 
excessive  bearing  friction  and  overloading  of 
the  motor  during  constant  use.  If  the  alignment 
cannot  be  done  accurately,  a  flexible  shaft 
coupling  should  be  used. 

Fourth,  any  different  tj^pe  of  motor  than 
a  clock  motor  should  be  checked  for  radio 
interference  before  construction  is  begun.  The 
synchronous  clock  motor  shown  caused  no  in- 
terference while  operating  inside  the  receiver, 
but  other  small  motors  could  generate  a  great 
deal  of  noise. 

Fifth,  the  115- volt  wiring  to  the  motor  should 
be  carefully  insulated.  Every  amateur  should 
realize  that  115  volts  a.c.  is  potentially  just  as 
dangerous  as  the  higher  d.c.  plate  voltages  found 
in  power  supplies.

QST  for 


AdjuBtment 

Adjusting  the  scanner  for  operation  is  not 
difficult  with  the  following  procedure: 

1)  Set  the  butterfly  capacitor  to  approximately 
the  center  of  its  capacitance  range  by  running 
the  motor  through  part  of  a  revolution. 

2)  Attach  the  lead  clips  in  parallel  with  the 
receiver  oscillator  tuning  capacitor.  On  the  NC-57 
this  is  the  capacitor  section  next  to  the  front 
panel.  The  lead  from  the  APC  padder  should 
attach  to  the  stator,  and  the  other  lead  to  the 
capacitor  frame. 

3)  Use  a  VFO,  crystal  oscillator,  or  signal 
generator  to  obtain  a  strong  signal  in  the  middle 
of  the  desired  band.  Tunc  in  this  signal  with 
the  receiver  tuning  dial.  Since  the  scanning  unit 
adds  capacitance  in  parallel  with  the  tuning 
capacitor  of  the  receiver,  the  setting  may  be  one 
to  several  hundred  kilocycles  higher  than  the 
normal  dial  setting. 

4)  Peak  the  signal  with  the  antenna-trimmer 
control  if  the  receiver  has  one. 

5)  Run  the  butterfly  capacitor  to  its  maximum 
and  minimum  settings  and  check  these  fre- 
quencies with  the  VFO  or  signal  generator. 
Then  adjust  the  APC  trimmer  to  more  capaci- 
tance for  a  wider  scanning  range  or  to  less 
capacitance  for  narrower  scanning  range.  (The 
total  capacity  added  by  the  unit  is  of  course  equal 

to  t; — r~rry    80)    by    decreasing    C2,    the    total 
Ci  -f-  C2 

capacitance  and  the  scanning  width  are  reduced.) 

6)  Repeat  Steps  3,  4,  and  5  until  the  desired 
range  is  covered. 

The  amount  of  receiver  tuning  capacitance 
in  use  is  different  on  each  amateur  band,  so  the 
scanner  must  be  readjusted  for  each  band. 

To  restore  normal  receiver  operation,  just 
unclip  the  scanner,  lift  it  out,  and  reset  the 
antenna   trimmer.    This   scheme   is,    of   course, 


not  useful  with  receivers  whose  tuning  ranges 
are  restricted  to  the  amateur  bands. 

Addendum 

The  scanning  capacitor  used  by  the  author, 
being  of  the  butterfly  type,  goes  through  its 
capacitance  range  four  times  for  one  complete 
revolution  of  its  shaft,  and  therefore  the  band  is 
swept  four  times  — ■  twice  in  each  direction.  The 
butterfly  type  with  ball  bearings  may  not  be 
generally  available  on  the  market.  However, 
the  standard-type  Hammarlund  VU-30  should 
make  a  satisfactory  substitute,  although  it  will 
take  twice  as  long  to  sweep  the  band  (twice  per 
revolution  instead  of  four  times).  The  VU-30 
has  a  maximum  resultant  capacitance  (two  sec- 
tions in  series)  of  31.5  mm^- 

To  obtain  an  idea  of  the  range  to  be  expected 
on  the  various  lower-frequency  bands,  the  ar- 
rangement of  Fig.  1  was  tried  on  a  Hallicrafters 
SX-71,  with  a  Johnson  21-nni.  capacitor  at  Ci, 
and  a  100-MMf-  unit  at  C2. 

With  C2  set  at  minimum,  the  band-set  on  the 
SX-71  had  to  be  readjusted  about  200  kc. 
higher,  and  the  tuning  range  of  Ci  was  approxi- 
mately 40  kc.  With  C2  set  at  maximum,  the  band- 
sot  had  to  be  set  about  300  kc.  higher,  and  the 
range  of  Ci  was  about  300  kc. 

On  40,  the  band-set  was  adjusted  about  200 
kc.  higher,  C2  at  minimum,  and  the  tuning  range 
was  about  40  kc.  With  C2  at  maximum,  the 
band-set  was  about  250  kc.  higher,  and  the  range 
slightly  over  300  kc. 

On  the  20-  and  10-meter  bands,  the  band-set 
adjustment  was  only  slightly  different  than 
normal.  On  20,  the  bandspread  range  of  C\  could 
be  varied  from  about  30  kc,  with  Ci  at  minimum, 
to  about  300  kc.  with  C2  at  maximum.  The  range 
on  10  was  about  2  Mc.  with  C2  at  minimum, 
and  with  C2  set  at  about  half  capacitance,  the 
entire  band  was  covered. 


This  simple  band-scanner 
can  be  thrown  together  in  a 
few  minutes.  The  ball-bearing

A  Tripler  for  the  1215-iyic.  Band 

Crystal- Controlled  Output  with  420-Mc.  Drive 
BY  RUSSELL  W.  ROBERTSON.*  W6DQJ 


•  Most  of  the  work  done  so  far  on  1215 
Me.  has  been  with  oscillator-type  rigs, 
which  leave  much  to  be  desired  in  the 
way  of  stability  and  efficiency.  Here  is  a 
solution  in  line  with  more  modern  tech- 
niques: a  tripler  that  can  be  driven  with 
a  low-poM'ered  420-Mc.  stage. 


NOW  that  the  design  of  stable  equipment  for 
the  420-Mc.  band  is  fairly  well  standardized, 
experimentally  inclined  hams  are  thinking 
of  going  higher  in  frequency.  Most  of  the  work 
done  so  far  on  1215  Mc.  and  higher  bands  has 
l)een  with  oscillator-type  transmitters.  This  can 
be  fun,  but  experience  has  shown,  as  on  all  lower 
bands,  that  if  we  are  to  accomplish  any  real  good 
it  must  be  with  something  more  stable  and  reUa- 
l)le  in  performance. 

Choice  of  tubes  for  use  as  frequency  multipliers 
or  r.f.  ampUfiers  is  limited  enough  at  420  Mc. 
When  we  go  to  1215,  there  is  practically  no 
choice  at  all.  The  lighthouse  types  such  as  the 
2C40  and  2C43  work  well  at  very  low  power,  but 
if  we  want  to  go  over  the  milliwatt  level  we  have 
only  the  2C39A  to  look  to.  There  are  bigger 
tubes,  of  course,  but  their  cost  puts  them  out  of 
the  reach  of  most  hams. 

Tank-circuit  design  definitely  leaves  the  coil- 
and-condenser  field  when  we  move  up  from  420 
Ale.  This  shift  from  coils  to  lines  to  cavities  leaves 
the  average  ham  wath  the  feeling  of  having  en- 
tered another  world,  but  construction  of  suitable 
cavities  (;an  be  managed  without  too  much  in  the 
way  of  machine  tools.  The  tripler  described  here 
is  a  combination  of  modified  surplus  and  home- 
made tank  circuits  that  should  not  be  beyond  the 
abilit.y  of  many  experimenters. 

The  photographs  show  the  tripler  in  both  as- 
sembled and  kiiocked-down  form.  The  input 
circuit  was  made  from  a  coaxial  tank  circuit  of 
an  r.f.  amplifier  from  an  ASB-series  receiver  de- 
signed for  450  to  500  Mc.  Enough  detail  is  ap- 
parent so  that  a  near  dupHcate  could  be  made,  if 
the  surplus  variety  is  not  available,  though  having 
the  ASB  cavity  makes  the  job  quite  a  bit  simpler. 
The  original  amplifier  was  designed  for  use  with  a 
446A  Ughthouse  tube,  but  most  of  the  parts  can 
be  salvaged  for  this  application  with  the  2C39A. 

Making  the  Cavities 

The  ASB  cavity,  if  used,  should  be  cut  apart 
carefully  so  that  it  is  1^  inches  long.  The  inside 
diameter  is  27-,  e  inches.  The  original  cathode 
ring  is  salvaged  for  use  as  a  plate  contact  for  the 
2C39A.  The  grid  ring  is  used  for  the  grid  contact

for  the  2C39A,  also.  Both  these  are  spring-contact 
finger  stock  and  are  probably  the  most  difficult 
parts  to  make  if  suitable  materials  are  not  at 
hand.  The  plate  line  of  the  446A  is  cut  to  a  length 
of  IJ-ie  inches,  and  then  slotted  to  take  the 
cathode  sleeve  of  the  2C39A.  The  insert  that 
originally  held  the  plate  contact  to  the  plate 
line  is  slotted  to  a  depth  of  about  ^{e  inch,  and 
then  pinched  together  slightly  to  fit  into  the 
heater  connection  on  the  2C39A.  Heater  voltage 
should  be  fed  through  shielded  wire.  Insert  the 


The  tripler  for  1215  Mc.  uses  a  2C39A  tube.  The 
stnall  cylinder  at  the  bottom  of  the  assembly  is  the  420-

normal  operation. 

heater  connection  in  the  end  of  the  tube  before 
putting  the  tube  into  the  cavity. 

The  radial  plate  cavity  is  made  of  thick-wall 
aluminum  tubing,  3  inches  inside  diameter  and 
^^^2  inch  long.  Silver-plated  brass  would  be  fine, 
if  you  can  manage  it.  Top  and  bottom  covers  are 
%  2-inch  aluminum,  fastened  to  the  cyhnder  with 
six  No.  4  screws  each.  The  bottom  cover  is  drilled 
and  countersunk  to  take  four  6-32  flat-head  ma- 
chine screws  that  hold  the  cathode  line  onto  the  as- 
sembly. The  ears  into  which  these  screws  thread 
are  integral  parts  of  the  ASB  tank  circuit. 

Both  grid  and  plate  contact  rings  are  insulated 
from  the  case  for  d.c,  but  there  must  be  capaci- 
tance to  the  case  to  make  the  cavities  function 
properly.  The  rings  are  separated  from  the  cavity 
l)y  sheets  of  Teflon,  though  any  good  insulation 
that  will  stand  heat  may  be  used.  The  grid  con- 
tact ring  is  held  to  the  cathode  side  of  the  bottom 
cover  by  a  round  sheet  of  flashing  copper,  2^ 
inches  in  diameter.  Tiu^  screws  that  hold  this  in 
place  must,  of  course,  be  insulated  from  either 
the  copper  plate  or  the  cover.  In  the  photograph, 
a  short  insulated  lead  for  the  grid  leak  is  shown

attached  to  a  lug  under  one  of  the  nuts  that  holds 
this  assembly  together.  The  screw  is  insulated 
from  the  cavity.  The  other  three  screws  are  in- 
sulated from  the  copper  plate,  but  not  from  the 
cavity.  The  plate  contact  ring,  on  the  top  of  the 
cavity,  is  treated  in  like  manner,  except  that  only 
three  screws  are  used.  One  of  these  makes  contact 
to  the  ring  and  is  used  for  a  plate-voltage  terminal. 
The  other  two  are  insulated  from  the  ring,  but 
not  the  cover. 

Inductive  coupling  is  used  for  both  input  and 
output.  Details  of  the  coupling  loops  should  be 
clear  from  the  photographs.  The  cathode  cavity 
is  tuned  by  means  of  a  disk  capacitor,  the  fixed 
plate  of  which  is  part  of  the  cathode  line.  The 
movable  plate  is  mounted  on  a  fine-thread  screw, 
which  rung  through  a  threaded  fitting  attached 
to  the  inner  wall  of  the  cavity.  The  end  of  the 
screw  is  slotted  to  permit  adjustment  from  outside 
the  cavity.  Coupling  out  of  the  cavity  can  be 
varied  by  turning  the  Type  N  coaxial  fitting. 
Maximum  coupling  is  with  the  loop  vertical.  This 
position  is  indicated  with  a  dot  of  red  paint  on  the 
sleeve  so  placed  that  it  lines  up  with  the  slot  in 
the  fixed  portion  of  the  fitting  when  the  loop  is 
vertical.  Normal  coupling  is  about  15  degrees 
from  the  vertical  position.  Tuning  is  done  with  a 
li  X  5;s  X  ^'s-inch  piece  of  copper,  fastened  to  a 
34-inch  polystyrene  rod  that  is  brought  out 
through  a  shaft  bearing.  Pulling  the  rod  out 
raises  the  tuning  range  higher  in  frequency. 
Normal  tuning  is  done  bj'  rotating  the  rod. 

Operation 

Drive  for  the  tripler  is  furnished  Ijy  a  9903 
tripler  to  432  Mc.  With  a  10,000-ohm  grid  re- 
sistor, grid  current  in  the  2C39A  is  about  12 
ma.,  dropping  to  10  under  load.  So  far  the  tube 
has  been  operated  at  no  more  than  450  volts,  as 
no  cooling  has  been  used.  At  this  voltage  the 
plate  current  dips  to  35  to  40  ma.  at  resonance. 


No  means  of  measuring  output  is  available,  but 
the  appreciable  dip  indicates  that  fair  efficiency- 
can  be  expected. 

Sufficient  cooling  for  low-power  operation  ma}' 
be  obtained  by  blowing  air  across  the  tube's 
plate  fins.  If  anything  approaching  the  maximum 
rating  for  the  tube  is  to  be  run,  a  cowling  should 
be  used  around  the  cooling  fins,  to  confine  the  air 
flow  where  it  will  do  the  most  good.  Air  should 
also  be  blown  through  the  cathode  cavity.  Holes 
should  be  drilled  in  this  cavity  for  ventilation, 
even  at  low  power  levels.  Air  flow  should  be  in- 
creased as  the  plate  dissipation  is  raised.  With  no 
cowling,  a  flow  of  10  cubic  feet  per  minute  will 
take  care  of  up  to  40  watts  plate  dissipation. 
With  a  cowling  just  larger  than  the  plate  fins, 
10  c.f.m.  will  allow  up  to  85  watts  dissipation. 
Running  the  maximum  of  100  watts  dissipation 
raises  the  air  requirement  to  about  13  c.f.m. 
There  should  be  a  forced  air  flow  through  the 
cathode  cavity  if  more  than  about  25  watts  dissi- 
pation is  anticipated. 

The  2C39A  should  be  inserted  into  and  removed 
from  the  cavity  with  care.  The  grid  plane  is 
held  to  the  glass  seal  with  only  a  ring  of  cement; 
it  can  be  broken  loose  very  easily  if  anj'  strain  is 
applied  to  the  grid,  cathode  or  heater  terminals. 
Remember,  too,  that  the  top  plate  is  hot  for  d.c. 
Do  not  attempt  to  handle  the  cavity  when  plate 
voltage  is  applied. 

In  a  cavity  very  similar  to  the  one  described 
here,  it  was  found  that  the  tube  could  be  made  to 
oscillate  b.\-  reducing  the  capacitance  in  the 
cathode  circuit.  The  grid  resistor  was  reduced  to 
1200  ohms  for  this  purpose.  The  oscillation  fre- 
quency was  around  1280  Mc,  l)ut  by  some  re- 
tuning  of  the  cathode  cavity  the  frequency  was 
changed  to  about  960  Mc.  0!)viously  some  accu- 
rate method  of  checking  frequency  should  be 
available  before  oper.it ion  oC  the  unit  as  .in  o.'scil- 
lator  is  attempted.

Subinterval  Markers  from  a  100-Kc. 

Crystal 

More  on  Simple  Secondary  Standards 
BY  W.  C.  SMITH.*  K6DYX 


BEING  in  possession  of  an  old  and  uncalibrated 
receiver,  the  article,  "50-Kc.  Markers  from 
a  100-Kc.  Crj'stal,"  QST,  July,  1954,  was  of 
particular  interest  to  me.  If  this  circuit  would 
divide  a  frequency  by  two,  why  not  by  five,  or 
even  ten,  and  yield  markers  ever}-  20  or  10  kc? 


The    crystal    calibrator    unit    complete    with   power 
supply. 

With  this  possibility  in  mind  and,  with  the  help 
of  H.  Minor,  KN6JIE,  the  circuit  of  Fig.  1  was 
assembled.  We  carried  out  extensive  tests  and

that  appeared  in  the  July,  1954,  issue. 
K6DYX  shows  how  additional  markers 
at  intervals  as  small  as  6%  kc.  may  be  ob- 
tained from  a  100-kc.  crystal.  Included 
is  a  series  of  graphs  that  help  to  explain 
the  manner  in  which  the  circuit  works. 


think  the  results  would  be  of  interest  to  other 
hams. 

Circuit  Operation 

It  was  immediately  apparent  that  the  expla- 
nation offered  in  the  original  article  is  incorrect. 
The  grid  resistor  has  little  effect  on  the  frequency 
of  the  subharmonics.  The  cathode  by-pass  capaci- 
tor is  likewise  ineffective,  although  there  is  an 
optimum  range  for  both  these  components  in 
their  effect  on  the  stability  of  operation. 

The  proper  explanation  seems  to  be  that  the 
relaxation  pulse  from  the  screen  circuit  is  fed 
to  the  LC  network  composed  of  L,  Ci  and  Cz 
through  the  crystal  operating  at  near  its  series 
resonant  frequency.  A  transient  oscillation  is 
excited  in  the  tuned  circuit  which,  for  50-kc. 
markers,  has  a  frequency  of  350  kc.  Thus  the 
grid  signal  consists  of  the  resonant  frequency  of 
the  crystal  with  the  frequency  of  the  tuned 
circuit   superimposed   upon   it    (Fig.   2A).   The

positive  crests  of  this  complex  wave 
trigger  the  tube  in  such  a  way  that  the 
screen  voltage  appears  as  in  Fig.  2B, 
and  the  output  voltage  as  in  Fig.  2C. 
There  is  little  or  no  synchronizing  action,  since 
the  crystal  does  not  feed  back  any  of  the  350-kc.

frequency  present  in  the  screen  voltage.  The 
cathode  bias  is  important,  because  the  tube 
triggers  as  its  grid  returns  from  beyond  cut-off, 
but  the  capacitor  across  the  cathode  resistor 
serves  only  to  stabilize  the  bias,  and  has  no  direct 
effect  on  the  frequency.  The  time  constant  of 
the  screen  circuit  should  be  less  than  the  period  of 
the  crystal  for  strong  relaxation  pulses.  In  this 
case  it  is  47K  X  100  M^f-  =  4.7  microseconds, 
whereas  the  period  of  the  crystal  is  10  micro- 
seconds. 

Other  Subharmonics 

The  existence  of  50  kc.  and  harmonics  thereof 
in  the  output  voltage  is  obvious  from  Fig.  2C. 
Here  every  second  one  of  the  100-kc.  sawtooths 
is  distorted.  According  to  the  theory  of  operation 
given  above,  it  should  be  possible  to  distort  every 
third  tooth  by  tuning  the  LC  circuit  to  333  J/^  kc. 
and  obtain  markers  every  33^  kc.  This  was  found 
to  be  the  case.  In  fact,  it  was  possible  in  our  set-up 
to  distort  the  sawtooths  at  any  periodicity  up  to 
the  15th,  yielding  markers  every  6^  kc. !  A  series 
of  frequencies  to  which  the  LC  circuit  was  tuned, 
the  ratio  of  these  frequencies  to  the  100-kc. 
fundamental,  and  the  separation  of  the  marker 
frequencies  is  shown  in  Table  I.  This  is  not  the 
only  series  that  will  produce  subharmonic  distor- 
tion in  this  way.  A  ratio  of  3/2,  5/2,  7/2,  9/2, 
etc.,  will  result  in  1/2  frequency  harmonics.  A 
formula  giving  the  frequency  of  the  tuned  circuit, 
L  with  Ci  and  C2  in  series  across  it,  is: 

Ft  =  nFi  ±  n 
Where  n  takes  on  integral  values,  Fi  is  the  funda- 
mental frequency,  and  Fh  is  the  frequency  separa- 
tion of  the  harmonics  it  is  desired  to  produce. 
This  formula  was  verified  in  our  experimental 
work,  but  the  frequencies  shown  in  Table  I 
seemed  to  work  out  best. 

Fig.  3  shows  the  grid-voltage  wave  and  the

output-voltage  wave  when  the  circuit  was  ad- 
justed for  10-kc.  separation  of  the  markers.  Note 
that  the  frequency  ratio  in  Fig.  3 A  is  clearly  31 
to  10.  The  adjustment  of  either  Ci  or  C2  is  rather 
critical  because  the  frequency  of  the  tuned  circuit 
must  be  within  a  few  hundred  cycles  of  310  kc. 
We  found  it  advisal)le  to  use  a  cathode-follower 
buffer  after  the  oscillator  circuit  to  avoid  detun- 
ing when  we  changed  loads.  Adjusting  the  funda- 
mental to  exactly  100  kc.  is  also  critical,  because 
tuning  the  LC  circuit  pulls  the  crystal  a  little 
and  it  is  necessary  to  readjust  C3. 

Adjustment  Procedure 

For  our  experimental  work  we  had  available 
rather  ideal  equipment  in  the  way  of  syncro- 
scopes  and  frequency  counters,  but  the  unit  has 
been  adjusted  from  scratch  and  used  in  the  home 
station  with  very  satisfactory  results.  The  best 
procedure  is  to  establish  oscillation,  and  adjust 
either  or  both  Ci  and  C2  until  clean  markers  are 
heard  on  the  station  receiver  at  100-kc.  intervals.

Then  tune  the  receiver  to  the  approximate  point 
where  the  subinterval  marker  is  desired  and 
adjust  either  or  both  Ci  and  C'2  until  a  clear, 
clean  marker  is  heard.  No  difficulty  at  all  was 
experienced  in  getting  markers  every  20  kc, 
but  for  closer  intervals  one  should  check  that 
t  here  are  the  required  number  between  the  100-kc. 
points  previously  noted.  After  the  marker  inter-

Construction 

The  unit  shown  in  the  photographs  includes  a 
cathode-follower  buffer  stage  and  a  built-in 
power  supply  with  voltage  regulation.  The  cir- 
cuits of  these  sections  also  appear  in  Fig.  1.  The 
components  are  assembled  on  a  7  X  7  X  2-inch 
aluminum  chassis.  The  power  transformer,  6H6 
rectifier  and  0D3/VR150  voltage-regulator  tube 
are  lined  up  along  the  right-hand  edge  of  the 
chassis.  At  the  left  are  the  100-kc.  crystal  (at 
the  rear),  the  oscillator  tube,  and  the  cathode- 
follower  tube.  A  coax  output  connector,  pilot 
lamp  and  power  switch  are  set  in  the  front  edge 
of  the  chassis. 

In  the  bottom  view,  at  the  top,  C3  is  to  the 
left,  and  C^  to  the  right.  Ci  may  be  seen  near 
the  center.  Clearance  holes  have  been  cut  in  the 
chassis  so  that  these  three  variable  capacitors 
can  be  adjusted  from  the  top  with  a  screwdriver.

QST  for 


Six  Meters  for  the  Beginner 

Part  III —  Transmitting  Equipment  and  Antennas 
BY  EDWARD  P.  TILTON,  WIHDQ 


THE  50-Mc.  band  is  attractive  to  the  fellow 
who  is  just  getting  started  in  that  it  is  still 
possible  to  do  interesting  work  on  6  with 
very  low  power.  Increasing  power  pajs  off,  of 
course,  but  plenty  of  good  stuff  has  been  worked 
with  no  more  than  a  few  watts.  The  kind  of  work 
you  expect  to  do  will  determine  how  much  power 
you  will  need. 

If  you  want  only  a  rig  that  will  give  you  a  good 
signal  locally,  there  is  little  reason  to  go  beyond 
the  receiving  tube  power  level.  Something  like 
the  rig  described  here  will  do  the  job  nicely,  and 
it  will  help  the  interference  problem  markedlj^  if 
you  sti(;k  with  low  power.  It  may  surprise  you  to 
learn  that  a  10-watt  rig  is  quite  capable  of  giving 
a  good  account  of  itself  when  the  band  is  open, 
too.  When  ponnWc-E  skip  communication  is 
possible  at  all,  signals  are  usually  quite  strong: 
thus  there  is  not  a  large  difference  in  results 
whether  high  or  Unv  power  is  used.  Under  border- 
line conditions,  the  extra  margin  over  the  noise 
that  the  high-powered  signal  enjoys  is  a  major 
factor  in  making  contacts,  but  there  is  probably 
no  field  in  which  low  power  works  out  to  better 
advantage  than  in  6-mcter  DX.  There  is  no  real 
QRM,  and  it  is  unlikely  that  there  ever  will  be, 
so  we  don't  need  high  power  to  override  other 
stations  on  the  same  frequency. 

High  power  does  pay  off  handsomely  in  one 
phase  of  v.h.f.  work.  To  have  a  wide  reliable  op- 
erating radius  you  have  to  lick  one  enemy:  the 
noise  level.  The  edge  of  your  normal  coverage 
is  the  point  at  which  your  signal  disappears  into 
the  receiver  noise.  This  is  farther  out  when  high 
power  is  used,  whether  you're  working  on  50, 
144,  220  or  420  Mc.  (That's  why  we  have  super- 
powered  TV  stations.)  If  your  signal  is  running 
S9  at  the  receiving  point,  increasing  power  from 
10  to  100  watts  (10  db.,  or  about  2  S-units)  won't 
sound  like  much.  But  if  you  are  just  a  whisker 
over  the  noise,  that  10  db.  will  put  j'ou  right  up 
there  in  the  solidly-readable  category. 

When  you're  after  that  additional  10  db.  of 
signal,  the  first  place  to  go  all-out  is  in  the  an- 
tenna. Decibels  come  easier  and  cheaper  there 
than  in  the  transmitter.  In  v.h.f.  work  it  is  ap- 
proaching the  ridiculous  to  increase  power  while 
using  an  ineffective  antenna.  On  80  you  may 
have  to  put  up  with  a  makeshift,  but  on  6  almost 
everyone  can  manage  an  array  that  will  give 
good  results. 

With  TV  antenna  components  and  rotators 
available  at  moderate  cost,  there  is  little  reason 
for  not  having  a  rotatable  array.  Even  a  dipole 
works  well  if  you  can  aim  it  in  the  right  direction 
for  every  station,  and  two  or  three  elements  will 
do  a  real  job.  If  you  have  to,  you  can  make  con- 


tacts on  6  with  an  antenna  designed  for  lower 
frequencies,  but  the  chances  are  that  it  won't 
do  nearly  as  well  as  even  the  simplest  rotatable 
antenna  system  designed  for  the  job.  If  j-ou  can 
put  up  a  4-element  arraj^  of  the  type  described  in 
all  recent  editions  of  the  Handbook,  j^ou'll  have 
gained  as  much,  in  respect  to  coverage  with  a 
dipole,  as  would  result  from  increasing  j'our 
transmitter  power  from  10  to  100  watts.  It  will 
pay  a  much  larger  dividend,  actuall}',  for  it  will 
increase  your  receiving  performance  by  at  least 
as  great  a  factor. 

A  Low-Cost  10-Watt  Transmitter 

The  little  rig  pictured  here  will  take  an  input 
of  10  to  15  watts,  when  used  with  a  300-volt  plate 


A  2-tuhc  50-.Mr.  traiismitter,  capable  of  running  10  to 
15  watts  input.  The  4-pin  connector  on  the  front  wall  of 
the  chassis  may  be  plugged  directly  into  the  modulator, 
or  a  cable  may  be  run  between  the  two  units.  Tip  jacks 
on  the  left  end  of  the  chassis  are  for  measuring  final-stage 
grid  and  cathode  current. 

supply,  and  it  can  be  adapted  readily  to  portable 
or  mobile,  as  well  as  home-station  use.  When  used 
in  conjunction  with  the  modulator  described  in 
QST  for  December,  1954,  it  makes  a  complete 
'phone-c.w.  transmitter  that  will  give  a  good  ac- 
count of  itself  on  6.  After  you've  made  your  start 
with  the  rig  as  described,  it  may  be  used  to  drive 
higher  power  stages  at  a  later  date. 

Two  dual  triode  tubes  are  used.  A  12AT7  serves 
as  an  overtone  oscillator  and  doubler,  using  8.3- 
or  25-Mc.  crystals.  Output  is  on  50  Mc,  driving  a 
12BH7  push-pull  amplifier.  The  second  tube  can 
also  be  a  12AT7,  but  the  larger  tube  handles  the 
power  more  readily.  The  rig  fits  a  5  by  7  by  2-inch 
aluminum  chassis,  with  plenty  of  room  to  spare. 

Building  the  transmitter  r.f.  section  and  modu- 
lator in  separate  units  is  highly  recommended, 
as  the  r.f.  section  for  another  band  can  be  plugged 
into  the  modulator  at  any  time.  If  you  decide  to 
make  changes  in  either  unit,  the  other  can  be  left

intact,  whereaa  a  revamping  operation  may  be 
rather  cumbersome  when  r.f.  and  audio  are  all 
on  one  chassis. 

Looking  at  the  top-view  photograph,  it  may  be 
seen  that  the  tube  sockets  and  the  tuning  capaci- 
tors, Ci  and  Cs,  are  mounted  along  the  center  line 
of  the  chassis.  The  oscillator-doubler  socket,  right, 
is  13^  inches  in  from  the  end.  The  doubler  capac- 
itor is  1  inch  to  the  left,  and  the  two  tube  sockets 
are  23^  inches  apart.  The  plate  tuning  capacitor, 
C5,  is  1 1<^  inches  to  the  left  of  the  amplifier  socket. 
The  output  jack  and  series-tuning  capacitor  are 
either  side  of  the  center  line,  %  inch  from  the  left 
edge  of  the  chassis.  The  oscillator  plate  coil  screw 
is  seen  at  the  far  right,  and  the  crystal  socket  is  in 
line  with  it,  nearly  obscured  by  the  tube.  The 
adjustment  screw  showing  in  front  of  C4  is  the 
balancing  capacitor,  Ci. 

Power  is  brought  into  the  transmitter  through 
a  4-pLn  fitting  on  the  front  wall  of  the  chassis. 
This  plugs  into  a  matching  fitting  on  the  ad- 
jacent wall  of  the  modulator  unit.  If  it  is  de- 
sirable to  mount  the  r.f.  and  modulator  units 
separately,  the  two  may  be  connected  by  a  4-wire 
cable  of  any  convenient  length.  On  the  left  edge  of 
the  chassis  are  two  pairs  of  tip  jacks  for  measur- 


ing the  final-stage  grid  current  and  cathode  cur- 
rent. The  cathode  jacks  may  also  be  used  for 
keying  the  rig  for  c.w.  operation.  It  will  be  noted 
that  one  jack  of  each  pair  is  mounted  directly  on 
the  chassis.  Obviously,  it  is  possible  to  dispense 
with  one  of  these,  using  one  grounded  jack  and 
two  insulated  ones,  if  you  wish  to  do  so. 

In  the  bottom  view  the  oscillator-doubler  tube 
socket  is  at  the  left.  The  12BH7  amplifier  socket 
is  in  the  middle,  with  the  tuned  circuit  and  output 
coupling  coil  at  the  far  right.  At  the  middle  of 
the  picture,  just  above  and  below  the  amplifier 
socket,  are  the  neutralizing  capacitors,  C2  and 
C3.  These  are  plastic  TV  trimmers,  supported  by 
the  wires  that  connect  them  into  the  circuit.  Note 
that  they  are  not  mounted  on  the  chassis.  The 
0.001-/xf.  by-pass  capacitor  in  the  12BH7  cathode 
circuit  should  be  connected  as  close  to  Pins  3  and 
8  as  possible. 

Photographs  of  the  modulator  unit  will  be 
found  in  December,  1954,  QST,  pages  27  and  30. 
Arrangement  of  modulator  parts  is  not  critical. 
The  complete  diagram  and  parts  required  are 
given  here,  so  that  the  unit  may  be  built  without 
reference  to  the  earlier  article,  if  necessary.  Some 
minor  modifications  are  included,  so  follow  the

diagram  given  here,  not  the  earlier  one,  in  wiring 
the  modulator.  The  power  supply  may  be  con- 
nected either  through  the  modulator,  or  directly 
to  the  r.f.  section.  This  permits  operation  of  the 
transmitter  on  c.w.  while  the  modulator  unit  is 
under  construction. 

The  modulator  was  shown  originally  with  a 
6V6GT  in  the  output  stage.  This  may  be  used 
with  the  50-Mc.  transmitter,  but  more  audio  can 
be  developed  with  a  6L6.  If  the  rig  is  used  for 
mobile  work,  retention  of  the  6V6GT  would  be 
advisable,  in  the  interest  of  lower  power  drain. 
When  the  latter  is  used,  the  total  power  drain, 
with  a  300-volt  supply,  is  less  than  100  ma., 
making  it  very  suitable  for  operation  from  a 
vibrator  or  generator  supply. 

Adjustment 

In  hooking  up  the  power  supply  a  cable  should 
be  made  up  with  a  4-pin  female  plug  (Amphenol 
78-PF4).  This  will  attach  to  either  Jg  or  /y-  The 
hot  side  of  the  6. 3- volt  circuit  (a.c.  or  d.c.)  should 
be  connected  to  Pin  1,  the  cold  side  and  the  nega- 
tive side  of  the  high-voltage  circuit  to  Pin  3.  The 
300-volt  lead  is  brought  to  Pin  2.  This  will  ener- 
gize the  oscillator,  doubler  and  audio  circuits, 
but  not  the  amplifier.  It  will  be  helpful  if  the 
power  supply  has  a  separate  filament  transformer 
for  the  transmitter  heaters.  In  this  way  the  tubes 
can  be  warmed  up  before  applying  the  plate 
power,  which  will  increase  tube  life.  It  will  also 
make  it  possible  to  operate  a  115-volt  a.c.  an- 
tenna relay,  connected  in  parallel  with  the  pri- 
mary of  the  plate  supply  transformer,  to  switch 
the  antenna  to  the  transmitter  when  the  plate 
power  is  applied. 

Connect  a  short  temporarily  between  pin  jacks 
J 3  and  Ji,  to  close  the  final  stage  cathode  circuit 
to  ground.  Connect  a  low-range  milliammeter, 
preferably  0-5  or  0-10  ma.,  in  pin  jacks  /i  and  J% 
to  measure  the  current  developed  in  the  final  am- 
plifier grid  circuit  when  drive  is  applied.  The 
positive  terminal  of  the  meter  is  connected  to  /2- 
If  a  low-range  meter  is  not  available,  a  100-ma. 


meter,  that  will  later  be  used  to  measure  the  final 
plate  current,  may  be  substituted.  It  will  be  hard 
to  read  current  accurately  on  this  scale,  however. 

If  a  power  supply  delivering  200  volts  or  so  is 
available  it  may  be  used  for  initial  tests  on  the 
r.f.  section.  If  a  300-volt  source  is  used,  do  not 
leave  it  on  longer  than  necessary,  until  the  stages 
are  tuned  up  properly,  as  damage  to  the  tubes 
may  result  during  off-resonance  operation.  With 
the  tubes  hot,  apply  plate  voltage.  Have  C4  set 
near  the  midpoint  of  its  tuning  range,  Ci  near 
minimum,  and  C2  and  C3  set  with  their  brass 
slugs  about  halfway  into  the  brass  sleeves.  If  the 
coils  are  the  proper  size,  and  the  circuits  properly 
wired,  there  should  be  grid  current  showing  on 
the  meter  connected  to  Ji  and  J2- 

Adjust  the  position  of  the  slug  in  Li  quickly  for 
maximum  amplifier  grid  current,  and  then  tune 
C4  to  see  if  it  can  be  increased  further.  Depending 
on  the  characteristics  of  the  crystal  used,  there 
may  be  oscillation  only  over  part  of  the  tuning 
range  of  Li.  In  this  case,  grid  current  in  the  am- 
plifier will  appear  suddenly  as  the  coil  slug  is 
tuned  through  the  resonance  point.  With  some 
crystals  oscillation  may  not  start  every  time  the 
plate  voltage  is  applied  if  the  coil  is  tuned  exactly 
"on  the  nose"  for  maximum  output.  With  it  set 
for  maximum  amplifier  grid  current,  apply  plate 
voltage  several  times  to  be  sure  that  the  crystal 
always  starts.  Should  it  not  do  so,  detune  the 
coil  slightly  until  easy  and  reliable  starting  is 
obtained. 

It  will  be  noted  that  the  plate  circuit  of  the 
doubler  has  a  center-tapped  coil  tuned  with  a  split- 
stator  capacitor.  R.f.  power  is  coupled  from  both 
ends  of  this  circuit  into  the  grids  of  the  amplifier. 
The  output  capacitance  of  the  12AT7  is  in  paral- 
lel with  the  upper  half  of  the  circuit,  so  some  extra 
capacitance  must  be  added  at  the  bottom  to 
achieve  balanced  drive.  This  is  done  with  Ci, 
which  should  be  adjusted  for  maximum  grid  cur- 
rent in  the  amplifier,  readjusting  C4  each  time 
the  setting  is  changed.  It  is  not  critical. 

Before  going  any  further,  the  frequencies  in

the  two  stages  should  be  checked.  This  can  be 
done  with  a  caHbrated  absorption  wavemeter  or 
grid-dip  meter.  Output  from  the  oscillator  should 
be  on  25  to  27  INIc,  the  doubler  between  50  and 
54  IMc.  Frequency  can  also  be  checked  with  a 
receiver  that  is  capable  of  tuning  these  ranges,  if 
you  can  be  sure  of  its  calibration.  This  is  a  some- 
what risky  business,  however,  as  many  spurious 
responses  may  show  up  in  the  receiver,  and  it  is 
often  difficult  to  tell  when  you  have  the  right 
signal  tuned  in. 

A  listening  check  should  be  made  to  determine 
that  the  frequency  is  crystal  controlled.  With  the 
receiver  b.f.o.  on,  the  signal  should  have  a  clear 
musical  tone,  and  the  frequency  should  show  very 
little  change  when  a  metal  object  is  moved  near 
the  oscillator  plate  coil,  Li. 

The  next  step  is  neutralization  of  the  amplifier. 
With  no  plate  voltage  on  the  12BH7,  tune  its

plate  circuit  (with  Cs)  through  resonance,  watch- 
ing for  variation  in  grid  current.  The  latter  is 
Hkely  to  drop  sharply  as  resonance  is  reached. 
Adjust  the  neutralizing  capacitors,  keeping  them 
at  approximately  equal  settings,  and  check  for 
the  amount  of  grid-current  dip  at  resonance,  in- 
creasing or  decreasing  the  capacitance  of  C2  and 
C3  until  the  grid-current  dip  disappears. 

Now  we're  ready  to  check  the  final  stage.  Con- 
nect a  0-100  milliammeter  between  Pins  2  and  4 
of  the  plug  on  the  power  cable.  This  wall  apply 
plate  voltage  to  the  final  stage,  and  indicate  its 
plate  current.  Tune  C5  for  minimum  plate  cur- 
rent, which  wall  be  about  5  to  10  ma.  Now  connect 
a  lamp  load  to  the  output.  This  can  be  a  10-  or 
15- watt  lamp,  or  four  No.  44  (blue-bead)  pilot 
lamps  connected  in  parallel.  None  of  these  lamps 
will  make  a  good  load,  but  any  will  do  for  the  ini- 
tial check.  With  the  load  connected,  tune  the 


series  capacitor  and  retune  the  plate  capacitor 
for  maximum  brilliance  in  the  load  lamp.  This 
should  show  an  output  of  about  5  watts,  with  an 
input  of  10  or  so.  The  position  of  the  coupUng 
coil,  Li,  should  be  at  the  point  of  lowest  coupling 
to  L3  that  will  give  the  desired  loading.  Normal 
plate  current,  under  load,  will  be  about  40  ma., 
with  a  300-volt  plate  supply. 

The  modulator  is  designed  for  use  with  a  crystal 
or  high-impedance  dynamic  microphone.  The 
speech  amplifier  stages  provide  adequate  gain,  so 
long  as  the  operator  speaks  directly  into  the 
microphone,  at  a  distance  of  not  more  than  two 
inches.  A  rough  check  on  the  required  voice  and 
gain  levels  can  be  obtained  by  watching  the  load 
lamp.  There  should  be  appreciable  brightening  of 
the  lamp  with  ordinary  speech. 

The  final  stage  may  be  keyed  for  c.w.  operation 
l)y  plugging  a  key  into  the  tip  jacks,  J3  and  J4. 
^Vith  the  key  open  no  current  will  be  drawn  by 
the  final  stage.  Stations  nearby  will  hear  the  os- 
cillator-doubler  output,  and  will  report  "back- 
wave"  when  the  key  is  up,  but  more  distant  sta- 
tions will  not  hear  this  radiation  to  an  appreciable 
extent.  The  cathode  jacks  may  also  be  used  for  a 
meter,  which  will  read  the  combined  grid  and 
plate  currents.  If  neither  key  nor  meter  is  con- 
nected, a  short  should  be  inserted  in  the  jacks  to 
close  the  cathode  circuit.  A  conventional  closed- 
circuit  jack  may,  of  course,  be  substituted  for  the 
tip  jacks. 

The  same  is  true  of  the  grid-current  jacks,  Ji 
and  J2,  except  that  a  resistor  is  connected  per- 
manently between  their  terminals,  so  whether  or 
not  a  grid  meter  is  connected  will  make  no  differ- 
ence in  the  operation  of  the  ampHfier. 

Normal  operation  of  the  transmitter,  with  300- 
volt  supply,  will  show  approximately  the  follow- 
ing indications: 

Oscillator  and  doubler  plate  circuits  — 

10  ma.  each.

antennas.  If  you  want  to  feed  your  array  with 
coaxial  line,  the  feedline  may  be  plugged  directly 
into  the  output  connector,  Js.  In  this  case  no 
further  coupling  devices  are  required,  and  adjust- 
ment involves  only  tuning  Ce  for  maximum  load- 
ing. Retune  C5  each  time  an  adjustment  is  made, 
to  be  sure  that  the  final  stage  is  tuned  for  mini- 
mum plate  current.  The  position  of  the  coupling 
loop,  L4,  should  be  set  so  that  35  to  40  ma.  plate 
current  is  drawn  with  the  antenna  connected. 

If  a  long  run  of  transmission  line  is  required  be- 
tween the  rig  and  the  antenna  system,  lower  line 
losses  will  be  encountered  if  open-wire  line  is  used. 
This  will  require  some  form  of  antenna  coupler  or 
balun,  to  take  care  of  the  transformation  from  the 
unbalanced  coax  to  the  balanced  open-wire  line.

What's  the  Answer? 

A  Question-and-Answer  Quiz  for  the  Beginner 

BY  LEWIS  G.  McCOY,  WIICP 


IN  answering  correspondence  from  amateurs 
around  the  countrjj^,  it  becomes  apparent  that 
certain  questions  repeat  more  than  others. 
This  would  indicate  that  the  same  problems  are 
shared  by  many  beginners  and  that  it  would  be 
helpful  to  have  an  article  in  QST  discussing  these 
problems.  People  seem  to  enjoy  quizzes  so  we 
have  listed  the  questions  in  bold-face  t^^pe  and, 
if  you  wish,  you  can  try  answering  them  before 
reading  the  explanations.  If  you  get  all  the  an- 
swers right  it  indicates  that  you  have  a  pretty 
fair  radio  IQ  for  a  beginner. 

1.  What  causes  key  clicks? 

There  are  two  typea  of  clicks.  One  is  caused 
by  electrical  sparking  at  the  key  contacts.  This 
is  the  same  type  of  electrical  noise  you  hear  in 
your  receiver  when  someone  in  the  house  turns 
on  an  electric  light  switch.  Depending  on  the  in- 
tensity of  the  spark  generated  and  the  associated 
wiring,  the  noise  can  cover  quite  a  wide  frequency 
range.  The  electrical  noise  from  this  sparking 
won't  travel  far  —  probably  not  more  than  a 
few  hundred  feet.  However,  it  can  cause  inter- 
ference to  neighbors'  radio  reception,  so  the 
clicks  should  be  eliminated.  This  type  of  click  is 
easy  to  cure;  a  simple  key-click  filter  (Fig.  1)  at 
the  key  contacts  will  usually  get  rid  of  it. 

The  second  t3^e  of  click  is  that  generated  by 
the  actual  turning  on  and  off  of  the  transmitted 
signal.  If  the  signal  goes  on  or  off  too  abruptly,

a  click  will  be  generated.  The  clicks  will  be 
strongest  close  to  the  frequency  of  the  trans- 
mitted signal  but  may  extend  far  enough  to 
cause  interference  across  an  amateur  band.  To 
get  rid  of  this  type  of  click  it  is  necessary  to 
"shape"  the  keying.  The  reader  should  study 
the  keying  chapter  in  The  Radio  Amateur's 
Handbook,  as  proper  treatment  of  shaping  pro- 
cedure is  beyond  the  scope  of  this  article. 

2.  What  causes  chirp? 

Chirp  is  a  change  in  frequency  as  the  trans- 
mitter is  keyed.  There  are  several  possible  causes 
for  the  frequency  change.  One  is  the  voltage 
change  on  the  oscillator  stage  from  the  key-up 
condition  to  key-down.  This  can  be  minimized 
by  regulating  the  screen  and  plate  voltages  of 
the  oscillator  stage. 


Another  common  cause  of  chirp  is  "pulling" 
of  the  oscillator  frequency  by  changing  condi- 
tions in  the  next  stage  or  stages  as  the  excitation 
is  applied  or  removed.  Changing  voltages  and 
currents  in  the  stages  following  the  oscillator 
"reflect"  a  variable  load  on  the  oscillator  and 
pull  the  frequency.  When  such  a  condition  exists 
it  is  necessary  to  have  more  or  better  isolation 
between  the  oscillator  and  the  changing  stage. 

When  persistent  cases  of  chirp  are  encountered 
with  several  different  crystals,  one  should  look 
at  the  circuit  adjustment.  An  overloaded  oscilla- 
tor can  make  any  crystal  chirp. 

3.  How  far  can  one  expect  to  work  with  a 
low-powered  transmitter  of  say  5  or  10  watts 
input? 


udw  POWER  errs  out." 


This  is  not  an  easy  question  to  answer  because 
of  the  many  variables  involved.  It  will  depend 
a  great  deal  on  the  location,  type  of  antenna 
used,  frequency,  time  of  day  and  year,  and  band 
conditions.  The  condition  of  the  ionosphere,  the 
region  above  the  earth  that  reflects  radio  signals, 
varies  with  the  time  of  day,  time  of  year,  and 
the  sunspot  cycle.  However,  it  would  be  safe  to 
state  that  with  a  fair  antenna,  and  exceptional 
band  conditions,  the  transmitted  signal  from  a 
5-  or  10-watt  station  can  reach  any  country  in 
the  world.  This  holds  true  for  any  amateur  band 
from  40  through  10  meters. 

One  amateur  using  approximately  35  watts 
input  worked  over  100  different  countries  on  the 
80-meter  band.  Many  Novices  have  worked  all 
48  states  using  very  low  power. 

4.  What  is  the  advantage  in  using  the  same 
antenna  for  transmitting  and  receiving? 

Nearly  all  antennas  will  give  better  perform- 
ance in  certain  directions  than  in  others.  To 
illustrate,  let's  assume  we  have  a  transmitting 
antenna  that  is  good  for  transmitting  in  the 
east-west  direction  but  is  poor  as  far  as  north 
and  south  are  concerned.  Suppose  we  have  another 
antenna,  used  for  receiving,  that  shows  good 
reception  on  the  north-south  path.  We  can  call 
our  heads  off  at  stations  on  the  north-south 
path  but  because  our  transmitted  signal  in  this 
direction  is  weak,  we  get  no  replies.  By  using 


34 


QST  for 


the  same  antenna  for  transmitting  and  receiving, 
we  eliminate  this  difficulty.  It  doesn't  mean  that 
everybody  we  call  is  going  to  come  back  but  at 
least  we  know  they  might  hear  us.  An  antenna 
relay  or  knife  switch  can  be  used  to  switch  the 
feeders  to  receiving  or  transmitting. 

5.  When  tuning  the  amplifier  plate  circuit, 
which  indication  is  the  correct  setting  for 
resonance  as  shown  by  the  plate  milliam- 
meter,  minimum  or  maximum  current? 

The  tuning  setting  that  gives  minimum  plate 
current,  or  the  "dip,"  is  resonance  in  the  plate 
circuit.  Normally,  the  "dip"  is  the  correct  setting 
for  getting  ma.ximum  output  from  an  amplifier. 
We  say  "normally"  because  in  amplifiers  using 
screen-grid  tubes,  ma.ximum  output  may  occur 
at  a  setting  slightly  different  than  the  "dip." 
The  safest  method  of  tuning  is  to  have  an  r.f. 
ammeter,  or  some  similar  indicating  device,  in 
the  feed  line  and  then  tune  the  transmitter  for 
maximum  output  as  indicated  by  the  r.f.  am- 
meter. The  final  amplifier  should  not  be  loaded 
beyond  the  rated  plate  current  of  the  tube  in  use. 

6.  What   does    "crystal-controlled"    mean? 

This  means  the  frequenc}'  of  the  oscillator 
stage  is  determined  by  a  quartz  crystal.  A  crystal 
wUl  only  oscillate  or  vibrate  at  a  certain  fre- 
quency, depending  on  the  dimensions  and  cut 
of  quartz  used  in  the  crystal.  Using  a  crystal- 
controlled  oscillator  is  one  method  of  making 
sure  the  transmitter  frequency  will  be  stable. 
In  addition,  the  transmitter  frequency  will  be 
accurately  known. 

The  FCC  requires  that  Novices  use  crystal 
control  of  their  transmitters. 

7.  What  is  a  harmonic? 


*WW&T  1$  A  «ARMOMlC?* 

■»-  ■■:mm}        -^^j  cO- 

A  harmonic  is  a  signal  that  is  an  integral  mul- 
tiple of  the  fundamental  frequency.  It  is  char- 
acteristic of  certain  tjT)es  of  r.f.  generation 
that  when  we  develop  a  fundamental  signal,  we 
also  generate  multiples  of  that  frequenc}'.  For 
example,  if  we  generate  a  signal  on  3700  kilo- 
cj^cles,  there  will  also  be  signals  present  at 
7400  kc,  11,100  kc,  14,800  kc,  etc.  Normally, 
these  harmonics  will  be  weaker  in  strength  as 
they  go  higher  in  frequency  but  in  many  cases 
they  will  be  strong  enough  to  cause  interference 
to  other  services  unless  we  do  something  to  at- 
tenuate them. 

8.  Why  are  filaments  and  heaters  necessary 
in  vacuum  tubes? 

When  an  electric  current  is  passed  through 
the  filament,  the  wire  heats  to  incandescence. 


In  a  vacuum,  when  the  wire  gets  hot  enough 
some  of  the  electrons  will  fly  off  the  filament 
and  cluster  around  it.  If  another  element  is 
inserted  in  the  tube  and  a  voltage  is  applied 
between  it  and  the  filament  (-f-  terminal  to  the 
n^yfi  element),  the  electrons  from  the  filament 
will  flow  to  the  added  element. 

The  emitter  of  electrons  in  a  vacuum  tube 
is  called  the  "cathode,"  and  the  filament  de- 
scribed above  is  a  "directly-heated  cathode." 
Indirectly-heated  cathodes  are  also  widely  used 
in  vacuum  tubes.  Here  a  thin  sleeve  of  metal 
is  coated  with  a  material  that  emits  electrons 
at  relatively  low  temperatures,  and  a  small 
heater  coil  is  contained  within  the  sleeve.  In- 
directly-heated cathodes  reduce  hum  problems 
in  audio  work  that  would  be  encountered  with 
filament-type  tubes. 

9.  How  does  a  rectifier  tube  act  to  change 
alternating  current  to  direct  current? 

As  one  can  see  from  the  explanation  of  Ques- 
tion No.  8,  the  filament  or  cathode  of  a  tube 
emits  electrons  which  flow  to  the  positive  plate 
element.  If  an  a.c.  voltage  is  applied  between 
plate  and  cathode,  one  half  of  each  cycle  of  the 
voltage  will  be  positive,  the  other  half  negative. 
During  the  positive  half  cj'cle,  electrons  from  the 
filament  will  flow  to  the  plate.  Current  will  not 
flow  during  the  negative  half  cycle.  This  gives  us 
a  pulsating  d.c.  which  can  then  be  run  through  a 
filter  to  smooth  out  the  ripple  that  will  be  present. 

10.  How  fast  does  a  radio  signal  travel? 

Radio  signals  travel  at  the  same  speed  as  light 
waves,  appro.ximately  186,000  miles  per  second. 
In  this  connection,  it  is  interesting  to  note  that 
recentlj'  two  amateurs  beamed  a  signal  at  the 
moon  and  then  listened  for  the  reflected  signal. 
The  signal  had  to  travel  a  distance  of  some 
440,000  miles  to  get  to  the  moon  and  back. 
With  radio  traveling  at  the  speed  of  light,  the 
distance  would  be  covered  in  about  23^  seconds. 
You  can  imagine  the  thrill  the  two  amateurs  ex- 
perienced when  they  sent  the  signal  and  then  a 
couple  of  seconds  later  heard  the  faint  "beep" 
of  the  returning  signal. 

11.  What  is  the  relationship  of  the  80-meter 
band  to  the  3.5-megacycle  band? 


They  are  the  same.  Probablj'  one  of  the  most 
confusing  things  the  newcomer  encounters  is  the 
reference  to  amateur  bands  by  either  meters  or

Lightning  Protection  for  the  Transmitting 

Antenna 

Grounded  System  for  Open-Wire  Feeders 
BY  R.  C.  CORDERMAN,*  W4ZG 


AN  old  adage  says  lightning  never  strikes  twice 
/\    in  the  same  place.  You  may  not  agree  with 
-^-^  this,  but  if  it  strikes  you  once  it  won't  make 
any  difference  whether  j^ou  do  or  don't  agree. 

Radio  amateurs  for  the  most  part  invite 
destruction  l)y  lightning  bj-  neglecting  to  provide 
any  protection  against  it.  The  antenna  usually 
associated  with  amateur  radio  transmitting 
equipment  is  most  vulnerable  to  lightning  due  to 
its  length  and  height.  To  validate  your  insurance, 
your  antenna  installation  must  comply  with  the 
National  Board  of  Fire  Underwriters  Electrical 
Code  which  saj's: 

Lightning  Arresters  —  Transmitting  Stations.  Except 
wliere  protected  by  a  continuous  metallic  shield  (coax) 
which  is  permanently  and  effectively  grounded,  or  the 
antenna  is  permanently  and  effectively  grounded,  each 
conductor  of  a  lead-in  for  outdoor  antenna  shall  be  pro- 
vided with  a  lightning  arrester  or  other  suitable  means 
which  will  drain  static  charges  from  the  antenna  system. 

A  similar  requirement  is  applicable  to  a  re- 
ceiving  antenna  should   it   extend   outside   the 


building  in  which  the  receiving  equipment  is 
located. 

Many  years  ago  ni}-  antenna  was  struck  by 
lightning.  At  that  time,  there  w'as  an  insurance 
lequirement  which  said  that  a  100-ampere 
switch  should  be  used  for  grounding  the  antenna 
when  the  station  was  not  in  operation.  The 
lightning  completely  destroj'ed  most  of  the 
antenna  wire,  burned  the  wooden  base  of  the 
lightning  switch  and  burned  the  insulation  off 
the  No.  4  copper  grounding  wire  between  the 
switch  and  the  ground  stake.  As  the  switch  was 
in'  the  grounded  position,  no  damage  to  the  house 
or  radio  equipment  resulted.

ages  can  build  up  on  an  antenna  due  to  other 
causes.  About  1920,  while  attending  Carnegie 
Tech,  Pittsburgh,  Penna.,  an  e.xperience  was 
observed  which  will  be  of  interest  in  this  connec- 
tion. The  antenna  at  8XC  consisted  of  10  wires 
600  feet  long,  approximately  165  feet  above  the 
ground  at  its  center.  It  ran  across  a  gully,  at  the 
bottom  of  which  was  a  mainline  railroad  track. 
When  locomotives  pulling  heavy  trains  passed 
under  the  antenna,  the  static  charge  built  up 
was  sufficient  to  cause  flash-over  of  an  8-inch  gap. 
The    flash    repeated    approximately    every    five

seconds  while  the  engine  was  immediately  be- 
neath the  antenna  and  less  frequently  when  it 
was  approaching  or  leaving  the  area  below  the 
antenna. 

Lightning  Arresters 

What  steps  should  we  take  to  protect  ourselves 
and  our  equipment  against  these  hazards?  You 
will  observe  that  the  Electrical  Code  specifies 
that  the  lead-in  may  be  a  coaxial  cable,  the 
shield  of  which  is  permanently  and  effectively 
grounded.  This  means  that  a  ground  connection, 
using  No.  4  wire  or  larger,  should  be  made  to  the 
shield  of  the  coaxial  cable  at  the  point  where  it  is 
nearest  to  the  ground  outside  of  the  house.  If 
the  cable  can  be  run  underground,  a  grounding 


36 


QST  for 


stake  should  be  located  at  the  point  where  the 
cable  enters  the  ground.  The  grounding  stake, 
to  be  effective  in  soils  of  average  conductivity, 
should  be  not  less  than  10  feet  long,  and  if 
possible,  plated  with  a  metal  which  will  not 
corrode  in  the  local  soil. 

When  open-wire  feeders  are  used,  a  lightning 
arrester  is  required.  The  type  of  lightning 
arresters  provided  for  residential  broadcast  and 
television   antennas   may   be   suitable   for   very 


twelve  years  these  gaps  were  in  use  there  was 
never  an  occasion  when  a  Ughtning  hit  came 
closer  to  our  house  than  a  half  block  when  a 
neighbor's  house  was  struck.  This  could  have 
been  a  happenstance  but  it  is  the  fact,  neverthe- 
less. In  the  Pennsylvania  Dutch  country  around 
Lancaster  and  York,  most  bams  nowadays  are 
protected  from  lightning  by  a  length  of  old 
trolley  wire  mounted  on  poles  extending  about 
10  feet  above  the  roof.  Both  ends  of  the  wire

low-power  installations  but  where  higher  power 
is  used,  they  are  inadequate,  since  the  radio- 
frequency  voltage  on  the  transmission  line  is 
usually  enough  to  cause  them  to  operate;  i.e., 
flaah  over. 

During  the  early  Thirties,  advice  was  obtained 
from  the  Naval  Research  Laboratory  at  Washing- 
ton, D.  C,  on  a  suitable  grounding  arrangement 
for  lightning  protection  for  a  1-kw.  installation.  It 
was  their  suggestion  that  a  spark  gap  be  provided 
between  each  of  the  two  open-wire  feeders  and  a 
center  contact,  grounded  with  No.  4  or  larger 
wire.  It  was  recommended  that  3^  X  J/2-iDch 
flat  brass  rod  shaped  as  shown  in  Fig.  1  be  used 
for  the  gaps.  Each  of  the  gaps  should  be  set 
sufficiently  far  apart  so  as  to  prevent  flash-over 
during  normal  operation  of  the  transmitter.  It 
was  found  that  because  of  the  standing  waves  on 
the  open-wire  line  a  gap  of  approximately  Ke 
inch  was  necessary. 

This  device  worked  very  well  during  thunder- 
storms as  it  would  start  sparking  intermittently 
when  a  storm  was  approaching.  As  the  storms 
passed  over  the  immediate  area,  the  frequency 
of  discharge  would  increase.  During  heavy 
thunderstorms,  there  was  a  steady  stream  of 
sparks  at  the  gaps.  It  was  possible  to  operate 
the  transmitter  with  relatively  Uttle  effect 
on  its  performance  even  while  the  static  charges 
were  jumping  across  the  equipment,  but  this  was 
seldom  done  because  of  a  personal  reluctance 
to  be  so  close  to  the  antenna  system.  It  has  been 
my  belief  that  a  properlj'-  installed  spark  gap 
on  an  antenna  system  drains  off  sufficient  static 
from  the  immediate  area  to  prevent  a  direct 
hit.  This  view  stems  from  that  fact  that  during  the 


are  grounded  and,  so  far  as  can  be  learned,  no 
barn  so  protected  has  suffered  Ughtning  damage. 

Direct  Ground  Connection 

Many  of  our  modern  antennas  permit  relatively 
simple  methods  of  direct  ground  connection, 
which  do  not  interfere  with  the  operation  of  the 
antenna.  Rotarj-  beams  using  a  T  or  gamma 
match  may  have  the  center  of  each  of  the  ele- 
ments, including  directors  and  reflectors,  grounded 
to  the  tower  on  which  they  are  mounted.  Two- 
and  six-meter  beams  should  have  the  supporting 
pole  grounded.  If  the  antenna  is  mounted  on  a 
wooden  pole  or  on  the  top  of  a  house,  a  No. 
4  or  larger  wire  should  be  extended  from  the  beam 
to  the  ground,  using  insulators  where  the  wire 
comes  close  to  the  building.  The  ground  wire 
should  be  spaced  away  from  metal  objects  such 
as  gutters,  etc.,  or  should  be  solidly  grounded  to 
them.  If  the  connection  to  such  objects  is  not  a 
good  one,  but  is  variable  in  resistance,  it  may 
be  a  source  of  spurious  signals  when  excited  by  the 
transmitter.  This  often  results  in  interference 
with  your  own  or  your  neighbors'  broadcast  or 
television  reception. 

For  the  past  seven  j-ears,  the  antenna  showai 
in  Fig.  2  has  been  used  at  W4ZG,  Winston- 
Salem,  N.  C.  It  gives  what  appears  to  be  good 
lightning  protection.  It  hasn't  been  hit  yet. 
And  best  of  all,  signal  reports  have  been  more 
than  satisfactory  on  power  comparisons  made 
tt-ith  other  stations  under  hke  conditions. 

The  antenna  may  properly  be  called  an  end- 
fed  Zepp.  Since  much  of  the  work  done  here  is 
on  the  "Tar  Heel  Net  frequency  of  3865  kc,  the

ENGWICHT  NEW  DIRECTOR 

Because  of  a  change  of  employment,  Ray  H. 
Cornell,  W6JZ,  recently  became  ineligible  to 
continue  as  a  director  of  the  League  from  the 
Pacific  Division.  In  accordance  with  Article  8 
of  the  Articles  of  Association,  the  Vice-Director, 
Harry  M.  Engwicht,  W6HC,  was  thereupon 
proclaimed  director  for  the  remainder  of  the 
term  expiring  at  the  end  of  this  year.  As  notice 
of  the  change  was  too  late  to  permit  Mr.  Eng- 
wicht to  attend  the  meeting  of  the  Board  of 
of  Directors  in  Hartford  May  13th-14th,  Mr. 
Cornell  represented  the  views  of  the  Pacific 
Division,  although  necessarily  without  vote. 
In  its  review  of  the  matter,  the  Board  of  Direc- 
tors set  March  14,  1955,  the  date  of  change  of 
employment,  as  the  effective  date  of  Director 
Engwicht's  office. 

7-MC.  NOVICE  SEGMENT  EXPANDED 

Three  years  ago  when  the  Federal  Communi- 
cations Commission  proposed  a  new  7-Mc.  band 
segment  of  7175-7200  kc.  for  Novice  use,  the 
League's  Board  of  Directors  heartily  endorsed 
the  idea  but  urged  that  the  segment  be  50  kc. 
in  width.  FCC  ruled  against  the  larger  band,  at 
the  time,  suggesting  that  operating  experience 
with  the  smaller  assignment  should  be  acquired 
first.  At  its  1954  meeting  the  Board  found  itself 
precisely  of  the  same  opinion  as  earlier,  and 
voted  to  recommend  an  expansion  to  7150-7200 
kc;  the  Commission  has  now  concluded  rule- 
making proceedings  in  the  matter  and  effective 
June  22nd  amended  our  rules  to  authorize  the 
full  50  kc.  for  Novice  use. 

R.E.T.M.A.  AMATEUR  COURSE 

Through  its  Amateur  Radio  Activities  Sec- 
tion, the  Radio-Electronics-Television  Manu- 
facturers Association  has  produced  a  text-and- 
records  course  in  theory  and  code  instruction 
aimed  at  the  Novice  Class  amateur  license.  The 
primary  interest  of  the  industry  association 
lies  neither  in  the  sale  of  this  item,  since  it  is 
non-profit,  nor  in  sales  of  amateur  equipment, 
but  rather  in  urging  that  more  people  take  up 
amateur  radio  aa  a  steppingstone  to  a  career  — 
the  objective  being  to  make  additional  trained 
personnel  available  to  meet  the  needs  of  the 
expanding  electronics  field.  RETMA  suggests 
that  its  course  will  have  particular  interest  for 
civil  defense  training  programs,  amateur  radio 
clubs,  hobby  groups,  schools  and  personnel  in 
all  branches  of  the  military  service. 

The  course  consists  of  an  illustrated  text  on 
basic  theory,  equipment  operation,  etc.;  an 
ARRL  License  Manual;  and  five  LP  records  of 
code    instruction.    Its    price    is    approximately 


$10;  the  course  may  be  secured  from  RETMA, 
777  14th  St.,  N.W.,  Washington  5,  D.  C.  A 
brochure  describing  the  course  is  available  free  of 
charge  upon  request. 

"LMS"  25TH 

The  transcribing  initials  which,  in  the  past, 
appeared  on  countless  thousands  of  letters  and 
bulletins  from  Hq.,  far  more  often  than  any 
other,  are  LMS  —  which  as  practically  every 
ham  in  Christendom  knows  stands  for  LiUian 
M.  Salter,  currently  Administrative  Aide  in  the 
ARRL  Communications  Department.  On  May 
12th,    "Lil"    marked   25   years   on   the   staff  — 


WIZJE 


being  the  seventh  Hq.  member  to  attain  that 
length  of  service. 

Miss  Salter  probably  knows  more  about  the 
day-to-day  operation  of  the  CD  than  anyone 
else.  She  is  the  link  between  policy  and  practical 
accomplishment.  Employed  originally  as  a  stenog- 
rapher, she  soon  acquired  administrative  duties: 
processing  and  editing  section  reports,  super- 
vision of  SCM  appointments  and  appointee 
records,  field-organization  supplies,  club  affilia- 
tions and  records,  to  name  a  few.  She  still 
personally  handles  the  master  stencils  for  the 
numerous  CD  bulletins  to  appointees  and  clubs. 
During  World  War  II,  with  the  title  of  Assistant 
Communications  Manager,  she  provided  an 
important  continuity  in  the  department  through 
a  succession  of  acting  communications  managers 
in  Mr.  Handy's  absence  on  mifitary  dutj'. 

Lil  Salter  managed  for  over  twenty  years  to 
keep  from  becoming  a  ham,  but  a  surge  of  en- 
thusiasm for  the  Novice  license  a  couple  of  years 
ago  caught  her,  too;  she  quickly  graduated  to 
General  Class,  and  is  now  WIZJE.  Don't  look 
for  her  on  the  air  around  the  middle  of  each 
month,  however;  it's  "copy  time"  for  QST 
section  reports,  and  evening  hamming  must  be 
foregone  for  overtime  work  in  their  editing  and 
processing.  That  is  t3T)ical  of  LMS  —  as  loyal 
and  as  conscientious  and  as  devoted  a  worker 
for  amateur  radio  and  the  League  as  has  ever 
graced  the  Hq.  staff.

LICENSE  PLATE  ACTIVITY 

Amateurs  in  several  states  have  been  actively 
promoting  the  issuance  of  call-letter  Ucense 
plates,  and  the  governors  of  four  states  and  the 
Territory  of  Hawaii  have  recently  signed  into 
law  the  coveted  legislation.  Thirty-one  states  now 
offer  this  privilege  and  Headquarters  continues  to 
provide  information  on  the  subject  to  individuals 
or  clubs. 

In  Utah,  W7NVY  was  appointed  to  head  the 
committee  which  saw  its  efforts  to  a  successful 
conclusion  on  March  11th,  when  the  Governor 
put  his  name  to  the  bill.  Maryland  amateurs 
W3EQK  and  W3PRL  were  instrumental  in  their 
state  in  having  Governor  McKeldin  sign  into 
law,  on  April  25th,  a  bill  which  authorizes  plates 
for  mobile  amateurs.  Meanwhile,  in  Pennsyl- 
vania, WSs  BN  QV  YA  ADF  EOZ  RSB  TBV 
and  VZJ  organized  a  drive  that  put  them  over 
the  top  on  May  3rd  when  Governor  Leader  made 
HB  561  into  law.  Hawaii  joined  with  the  Canal 
Zone  and  Alaska  on  May  5th  when  the  Governor 
signed  Act  67.  Sparked  by  W9EU,  W9BHT, 
W9PVD,  and  W9UQT,  in  Illinois,  Governor 
Stratton  signed  the  new  law  on  May  11th  ;  it 
took  three  years  to  get  this  act  through,  and  a 
committee  of  more  than  thirty  coordinated  the 
complete  coverage  that  spelled  success  in  their 
state.  On  May  26th  Connecticut  became  the  latest 
State  to  join  the  parade  when  Governor  Ribicoff 
signed  SB  23  into  law. 

EXAMINATION  SCHEDULE

ARE  YOU  LICENSED? 

•  When  joining  the  League  or  renewing 
your  membership,  it  is  important  that 
you  show  whether  you  have  an  amateur 
license,  either  station  or  operator.  Please

the  invitation  of  the  Board  as  non-participating  observers, 
were  New  England  Division  Vice-Director  Clayton  C. 
Gordon  and  Central  Division  Vice-Director  George  E. 
Keith.  There  were  also  present  Treasurer  David  H.  Hough- 
ton, Technical  Director  George  Grammer,  Assistant  Secre- 
tary John  Huntoon,  and  Quayle  B.  Smith  of  the  General 
Counsel's  office. 

2)  On  request  of  tlie  President,  Vice  President  Groves 
assumed  the  Chair.  Whereupon,  on  motion  of  Mr.  Dosland, 
the  following  resolution  was  unanimously  ADOPTED,  by 
rising  vote  (applause) : 

WHEREAS,  on  January  1,  1955,  Alex  Reid,  VE2BE, 
completed  25  years  of  continuous  service  as  a  member 
of  the  Board  of  Directors  of  The  American  Radio  Relay 
League,  Inc.,  representing  the  League  members  in 
Canada,  and 

WHEREAS,  his  fellow  directors  on  the  Board  are 
mindful  of  the  benefits  which  have  accrued  to  the  Board 
as  the  result  of  his  long  experience  and  wise  counsel,  and 

WHEREAS,  it  is  their  desire  to  make  known  to  Alex 
Reid  their  deep  affection  for  him  as  a  respected  associate 
and  beloved  fellow-amateur,  and 

WHEREAS,  the  Board  wishes  to  express  to  him  its 
sincere  best  wishes  for  liis  continued  success  and  happi- 
ness for  many  years  to  come 

Now,  therefore,  BE  IT  RESOLVED,  that  the  Board 
of  Directors,  meeting  in  Hartford,  Connecticut,  on  May 
13,  19.55,  in  recognition  of  Alex  Reid's  untiring  efforts 
on  behalf  of  the  League,  does  hereby  express  to  him  its 
congratulations  and  deep  appreciation  of  his  quarter  cen- 
tury of  loyal  and  intelligent  devotion  to  the  best  interests 
of  amateur  radio  and  the  League. 
Whereupon,  Mr.  Dosland  resumed  the  Chair.  Mr.  Reid 
spoke  briefly  in  appreciation. 

3)  Moved,  by  Mr.  Born,  that  the  Board  invites  Ray  H. 
Cornell,  of  the  Pacific  Division,  to  attend  tliis  meeting  as 
an  observer,  with  the  right  to  participate  in  discussions,  but 
without  the  right  to  vote;  and  further  that  the  Board 
authorizes  reimbursement  of  the  expenses  incidental  to  his 
attendance.  Moved,  by  Mr.  Maer,  to  amend  the  motion 
to  add  "and  that  the  Board  ratifies  the  action  of  the  officers 
of  the  League  in  this  matter."  Moved,  by  Mr.  Brabb,  further 
to  amend  the  motion  to  add  the  words  '  'and  that  all  Board 
members  are  instructed  to  review  the  matter  of  their 
eligibility  to  serve  and  to  resign  should  they  find  themselves 
ineligible  by  reason  of  their  employment";  but,  after 
discussion,  Mr.  Brabb  withdrew  the  motion  to  amend. 
The  question  then  being  on  the  original  amendment,  the 
same  was  unanimously  ADOPTED.  (At  this  point,  Atlantic 
Division  Vice  Director  Charles  O.  Badgett,  General  Counsel 
Paul  M.  Segal,  and  Ray  H.  Cornell,  of  the  Pacific  Division, 
entered  the  meeting.)  Unanimous  consent  being  given,  Mr. 
Cornell  discussed  the  circumstances  resulting  in  his  vacating

that  the  Planning  Committee  shall  study  the  matter;  but 
the  motion  to  amend  was  rejected.  The  question  then  being 
on  the  original  motion,  the  same  was  unanimously  rejected. 

24)  Moved,  by  Mr.  Rand,  that  the  Board  direct  the 
Planning  Committee  to  study  a  method  of  promoting 
diversification  of  operating  and  use  of  bands  by  establishing 
an  annual  award  for  the  "  Typical  Ham  "  of  the  year  in  each

ment section  will  be  all  new  every  two  years,  instead  of  the 
present  every  three  years;  but  there  was  no  second,  so  the 
motion  was  lost. 

26)  Moved,  by  Mr.  Anderson,  that  the  General  Manager 
investigate  the  establishment  of  appropriate  awards  for 
mobile  operation  —  both  as  to  physical  size  and  merit 
requirements.  Moved,  by  Mr.  Brabb,  to  amend  the  motion 
so  that  the  Merit  Award  Committee  would  investigate  the 
establishment  of  such  an  award;  but  there  was  no  second,

on  the  original  motion,  the  same  was  rejected. 

27)  On  motion  of  Mr.  Anderson,  VOTED,  that  it  be

30)  Moved,  by  Mr.  Born  (on  behalf  of  Mr.  Cornell), 
that  the  Planning  Committee  be  instructed  to  work  out  a 
practical  solution  to  the  matter  of  mobile  log  keeping 
and  that  it  be  abolished,  or  kept  to  a  minimum.  It  is  sug- 
gested that  as  a  basis  of  consideration,  that  if  log  keeping 
by  mobile  stations  cannot  be  abolished  entirely  that  a 
"Trip  Sheet"  log  be  kept,  recording  time  of  starting  and 
ending  a  trip  —  route  covered,  frequency  and  mode  of 
operation.  But  the  motion  was  rejected,  4  votes  in  favor  to 
7  opposed. 

31)  Moved,  by  Mr.  Joos  (on  behalf  of  Mr.  Cornell), 
that  to  implement  and  modernize  the  DX  Section  of  the 
ARRL,  an  unpaid  committee  be  set  up,  whose  recommenda- 
tions, arrived  at  by  joint  agreement  of  a  committee  two 
thirds  majority,  be  carefully  considered  by  the  ARRL  in  its 
DX  policies,  particularly  as  to  the  following;  a)  DX  con- 
test rules;  b)  DX  country  list;  c)  DX  awards.  This  com- 
mittee to  consist  of  one  member  from  each  of  the  ten  highest 
scoring  clubs  in  the  official  ARRL  DX  contest  tabulations 
annually,  club  committee  membership  to  begin  each  year 
on  January  first  following  the  publication  of  the  official 
club  scores  in  QST,  plus  any  other  important  DX  group 
or  individual  deemed  helpful  by  the  ARRL.  No  committee 
membership  to  be  longer  than  one  year  unless  the  same 
club  is  qualified  in  each  succeeding  year  by  its  official  score 
remaining  among  the  top  ten.  Representative  member  to  be 
selected  by  each  club  from  among  its  members.  All  com- 
munication between  the  committee  members  and  between 
the  committee  and  the  ARRL  to  be  by  means  of  corre- 
spondence. Nothing  in  this  proposal  shall  preclude  any 
individual  or  club  from  making  proposals  either  to  the 
ARRL  direct  or  to  the  committee  for  approval  if  con- 
sidered of  merit.  Moved,  by  Mr.  Brabb,  that  the  Board  now 
constitute  itself  a  Committee  of  the  Whole  for  the  purpose 
of  considering  this  matter;  but  there  was  no  second,  so  the 
motion  was  lost.  On  motion  of  Mr.  Brabb,  unanimously 
VOTED  that  the  matter  is  laid  on  the  table. 

32)  On  motion  of  Mr.  Maer,  after  extended  discussion, 
unanimously  VOTED  that  the  salary  of  the  General  Man- 
ager is  increased,  effective  this  date,  to  $18,000  per  annum. 
(Mr.  Maer  requested  that  the  minutes  show  that  all  Head- 
quarters personnel  in  attendance,  some  of  whom  are  mem- 
bers of  the  Board,  requested  leave  to  absent  themselves 
from  the  meeting  during  the  discussion  of  salaries  and  so 
absented  themselves.)  During  the  absence  of  Secretary  Bud- 
long,  in  the  discussion  of  this  matter,  the  Chair  appointed 
Quayle  B.  Smith  to  record  the  proceedings  of  the  meeting. 

33)  Moved,  by  Mr.  Joos,  that  the  General  Manager 
investigate  the  feasibility  of  a  questionnaire  similar  to  that 
recently  sent  out  by  the  New  England  Division  Director  to 
all  League  members  for  information  purposes;  but  the 
motion  was  rejected. 

34)  Moved,  by  Mr.  Joos,  that  the  Board  instruct  the 
General  Manager  to  print  in  QST  quarterly  a  simple  earn- 
ings and  balance  sheet;  but  there  was  no  second,  so  the 
motion  was  lost. 

35)  Moved,  by  Mr.  Crossley,  that  the  League,  through 
its  General  Manager,  request  the  Federal  Communications 
Commission  to  make  a  restriction  in  the  2-meter  band 
(144-148  Mc).  That  c.w.  operation  be  restricted  to  the 
lowest  100  kc.  of  the  band.  But  there  was  no  second,  so  the 
motion  was  lost. 

36)  Moved,  by  Mr.  Crossley,  that  the  Secretary  hereafter 
shall  give  informal  notice  to  the  directors  that,  on  (date) 
the  official  notice  for  the  special  meeting  of  the  Board  will 
be  made.  That,  if  there  are  any  matters  which  relate  to  the 
Articles  of  Association,  notice  of  these  changes  must  be 
filed  with  the  Secretary,  in  his  office  at  West  Hartford 
before  that  time  to  be  legally  included  in  the  Call  for  the 
Special  Meeting.  But  there  was  no  second,  so  the  motion 
was  lost. 

37)  The  Board  was  in  recess  for  dinner  from  6:16  p.m. 
until  8:47  p.m. 

38)  Moved,  by  Mr.  Crossley,  that  the  Board  instruct 
the  General  Manager  of  ARRL  to  write,  edit,  and  publish 
a  Novice  Technical  Handbook  or  Manual,  which  shall 
include  the  fundamentals  of  electricity  and  radio,  as  applied 
to  the  level  of  technical  knowledge  of  the  Novice  amateur 
so  that  he  may  advance  to  be  better  able  to  read  and  under- 
stand the  higher  level  Handbook;  but,  after  discussion,  the 
motion  was  rejected. 

39)  Moved,  by  Mr.  Crossley,  that  the  Board  establish  a 
"Student  Grade"  of  ARRL  membership  much  like  the 
Bimilar   grade   established   by   the   Engineering   Societies.

sary meals  or  one  night  in  a  hotel  if  a  meeting  is  over  50 
miles  from  the  SECs  home,  or  highway  tolls  involved,  for 
example,  reimbursement  in  excess  of  mileage  may  be  made 
in  a  reasonable  amount  per  SEC  organization  meeting, 
this  to  be  approved  by  the  Communications  Manager, 
provided  that  each  miscellaneous  expenditure  must,  to  be 
reimbursed,  be  itemized  and  submitted  with  the  travel 
claim.  In  the  case  of  the  SECs  of  Alaska,  Canal  Zone, 
Hawaii  and  the  West  Indies,  no  specific  provisions  as  to  the 
number  of  trips  reimbursed  shall  apply  but  reimbursements 
will  otherwise  be  guided  bj-  customarj'  provisions,  with  the 
applicable  limit  of  $150  per  annum  as  a  maximum  that

motions  which  have  been  passed  by  the  Board  at  this 
meeting;  but  there  was  no  second,  so  the  motion  was  lost. 

61)  On  motion  of  Mr.  Maer,  the  following  resolution  was 
unanimously  ADOPTED: 

RESOLVED,  that  the  Board  of  Directors  hereby 
compliments  the  staff  of  QST  for  its  fine  work  in  produc-

ods used  by  ARRL  and  others  in  selecting  those  lists  and 
that  the  results  of  this  meeting  be  reported  back  to  the 
Board  in  meeting  with  recommendations;  but  there  was  no 
second,  so  the  motion  was  lost. 

63)  On  motion  of  Mr.  Anderson,  the  following  resolution 
was  unanimously  ADOPTED : 

WHEREAS,  Hugh  L.  Caveness.  W4DW,  had  for

QST  for 


Hints  &  Snarls  -  GVZ  Style 


BY  J.  P.  JESSUP,*  W2GVZ 


THE  HANDBOOK  lias  it  all  wTOiig.  It  is  chuck 
full  of  dope  on  what  to  do  but  there's  not  a 
dern  word  about  what  not  to  do.  For  34 
years  in  ham  radio  I've  needed  a  book  that 
starts  off,  "Listen,  Stupid,  don't  ever  do  it  like 
that."  To  be  a  ham  you've  eventually  got  to  be 
a  plumber,  steeplejack,  ditchdigger,  electrician 
(not  a  libel  on  a  respectable  profession)  and  many 
other  things.  I  can  louse  up  an,y  of  those  special- 
ties with  practically  no  effort.  Let  me  show  j-ou 
what  I  mean. 

Now  take  porcelain  insulators.  They  are  useful 
gadgets  with  a  breaking  point  of  one  ounce  les.s 
pressure  than  I  alwaj^s  exert.  Wonder  if  it's 
tight  enough.''  One  more  turn  and  C-R-U-N-C-H. 
They  should  have  said,  "Go  easy,  you  big  dope." 
In  ye  good  ol'  days  I  used  to  paint  panels  with  a 
graphite  mixture  shorting  everything;  now  I  put 
plastic  spray  on  everything,  connecting  nothing. 

I  am  the  kind  of  guy  who  can  talk  to  a  local 
with  the  final  turned  off  and  then  forget  and  call 
DX  —  minus  final  —  for  two  hours  afterward. 
It  isn't  enough  to  tell  me  how  to  wire  the  switch 
—  you've  got  to  tell  me  to  turn  it  on ! 

Oh  yes,  I  really  have  a  penchant  for  pulling 
plate  caps  off  807s  when  removing  the  safety 
caps,  even  when  I  accidentally  let  them  cool  off 
first.  But  my  real  triumph  was  a  4-125A.  Think- 
ing it  was  shot  anyway,  I  yanked  the  safety  cap 
off  while  it  was  still  hot,  thereby  pulling  off  tlie 
plate  cap  and  breaking  the  glass.  Then  I  find  out 
it  was  OK!  Charge  off  twenty-five  bucks  more 
to  experience. 

When  I  was  your  age,  I  used  to  put  the  trickle 
charger  on  reversed  polarity,  cooking  the  storage 
battery  to  a  smelly  crisp.  Now  I  drop  hot  solder 
in  my  shoe  while  up  a  ladder.  The  tattoo  on  my 
wrist.''  That's  where  I  once  laid  down  the  solder- 
ing iron. 

Connecting  both  sides  of  a  capacitor  to  the 
same  terminal,  putting  high  voltage  on  the  fila- 
ment, drilling  through  a  panel  and  into  a  hard- 
wood floor  —  elementary.  Only  GVZ  could  get 
his  hands  on  a  blinker  socket  and  wire  it  into  the 
primary  of  the  high-voltage  circuit.  You  think 
you've  got  troubles.'  One  guy  topped  me,  though. 
He  accidentally  left  his  beam  turning  all  night

and   couldn't   understand    the   QSB    reports   he 
was  getting. 

The  Handbook  I  need  (and  Lrother,  so  do  you) 
should  go  something  like  this: 

Inside  Construction  Techniques 

1)  Never  drop  pliers  on  the  866s.  You  are  apt  to 
bend  the  pliers  or  melt  them  in  the  resulting  arc. 

2)  If  you  must  use  a  razor  blade,  wipe  the  blood 
off  the  wire.  Corrosion,  you  know. 

3)  When  tacking  up  300-ohm  line  in  the  attic 
flatten  the  thumbtack,  not  .  .   .  YOW! 

4)  Pick  out  nonconductors  to  droi>  in  the  rig, 
you  old  butterfingers! 

5)  Always  wait  two  months  before  using  any  dia- 
grams in  radio  magazines.  That  gives  the  editors 
time  to  sneak  in  the  inevitable  correction:  "Con- 
nection 6  should  have  been  made  to  this  gimmick 
instead  of  that  one." 

6)  Never  dislocate  a  knee  by  crouching  down 
working  on  the  rig.  For  the  sake  of  my  various  in- 
surance records,  that  one  shows  up  as  crouching 
down  to  change  a  tire. 

7)  Never  use  celluloid  coil  forms.  Maybe  you 
ain't  got  big  enough  lungs  to  blow  out  the  flames 
in  one  mighty  puff. 

8)  Don't  ever  sit  on  the  floor  for  hours  stuffing 
beam  elements  with  rock  wool  using  the  XYL's 
broomstick,  only  to  find  out  that  some  big  brain 
invented  insulating  pellets  that  you  can  simply 
pour  in. 

9)  Bounce  a  tube  on  the  floor  with  impunity  but 
never  toss  it  six  inches  onto  a  featherbed  —  that's 
fatal! 

Outside  Construction  Techniques 

1)  It  takes  two  men  to  put  up  a  skywire  on  an 
icy  roof;  one  to  catch  the  other  as  he  slips  over  the 


*337  HamUton  Ave.,  Glen, Rock,  N.  J.

edge.  Any  ol'  timer  will  tell  you  no  antenna  will 
work  unless  it's  erected  in  temperatures  below  15 
degrees.  It  helps  to  leave  hunks  of  your  hide  stick- 
ing to  it. 

2)  If  you  must  stand  on  a  12-foot  ladder  and 
chop  through  a  limb  as  thick  as  your  thigh  to  clear 
the  beam,  get  the  heck  down  pronto  when  she  starts 
to  go  (one  jump  recommended). 

3)  When  throwing  a  rope  with  rock  attached  up 
over  a  limb,  remember  Newton's  Law  of  Gravity. 
This  goes,  too,  for  "OF  Slippery  Mitts"  on  top  of 
the  pole  with  block  and  tackle  while  you  are  trust-

LOW-NOISE  RECEIVER  DESIGN 

1645  Cameron  Drive 
Lemon  Grove,  Calif. 
Technical  Editor,  QST: 

In  the  March  issue  the  article  on  "  Low-Noise  Receiver 
Design"  by  Longerich  and  Smith  was  to  me  both  interesting 
and  profitable,  since  it  enabled  me  to  bring  my  receiver 
up  to  an  acceptable  level.  I  have  an  old  HQ-120-X  which 
I  bought  a  couple  of  years  back  for  $65.  My  first  attempt 
at  improving  the  performance  involved  changing  the  grid- 
cap  tubes  for  more  modern  single-ended  types  of  higher  ffm. 
This  resulted  in  considerable  improvement  on  the  lower 
bands,  but  in  substantially  no  improvement  on  the  bands 
above  7  Mc.  Belie\'ing  at  the  time  that  the  trouble  lay  in 
poor  image  rejection  (with  an  i.f.  of  455  kc.  and  only  one 
r.f.  amplifier  this  is  a  possibihty)  and  in  oscillator  pulling, 
I  was  in  the  process  of  changing  over  to  dual  conversion 
on  the  three  high  bands  of  the  receiver  (above  5.7  Mc.) 
with  a  first  i.f.  of  5.0  Mc.  However,  before  I  had  gone  very 
far  with  this  I  noticed  the  above  article,  and  it  has  done 
the  trick.  The  cathode  follower  on  the  oscillator  has  elimi- 
nated the  pulling  (if  there  was  actually  an  appreciable 
amount  present),  and  the  increase  in  r.f.  tank  circuit  Q 
occasioned  by  the  use  of  the  cathode  followers  has  improved 
the  image  ratio.  This  increase  in  Q,  incidentally,  has  made 
the  tracking  more  critical,  but  not  enough  so  to  be  a  serious 
problem.  But,  of  course,  the  major  improvement  has  been 
in  the  terrific  reduction  in  receiver  self-noise.  I  now  feel 
that  I  have  a  receiver  which  is  equal  or  superior  to  anything 
in  the  $300  class. 

There  were,  however,  several  items  in  the  article  which 
I  feel  were  mistakes,  and  others  which  were  open  to  con- 
siderable question.  One  of  the  items  you  pointed  out,  which 
was  that  two  r.f.  amplifiers  are  not  necessarily  better  than 
one,  since  the  primary  function  of  the  r.f.  stage  (noise-wise) 
is  to  override  the  noise  of  the  mixer.  (Of  course,  for  image- 
rejection  purposes,  the  more  r.f.  stages  the  better,  but  the 
law  of  diminishing  returns  sets  in  very  rapidly.)  In  the 
present  instance  one  r.f.  stage  is  more  than  ample  from  the 
noise  consideration,  since  the  equivalent  noise  resistance  of 
a  6AC7  triode  mixer  is 


fie,   =   4    ^  ffc    =   4    -h   (ffm    -^  4)     =     16     H-   ffn

which  is  about  1450  ohms!  (The  equations  used  may  be 
found  on  page  937  of  Radiotron  Designer's  Handbook,  4th 
ed.)  Therefore,  the  limiting  resistance  for  noise  production 
is  the  r.f.  stage,  which  has  an  iJeq  =  2.5  -i-  gm  =  230  ohms. 


Let  me  back  up  a  bit  and  substantiate  that  "therefore" 
in  the  last  sentence.  Assuming  a  minimum  gain  of  ten  times 
from  the  grid  of  the  r.f.  stage  to  the  grid  of  the  mixer,  the 
effective  resistance  of  the  mixer  at  the  grid  of  the  r.f.  stage 
would  be  1450/10  or  145  ohms.  The  gain  of  the  r.f.  stage  in 
the  original  receiver  was  10,  and  if  anything,  it  is  greater  in 
the  present  configuration.  This  is  based  on  the  consideration 
that  the  ^  of  a  triode-connected  6AC7  is  40,  and  the  Q  of 
the  tank  circuit  has  been  increased.  Hence,  the  mixer  re- 
sistance translated  to  the  r.f.  grid  would  be  less  than  145 
ohms,  and  the  230  ohms  of  r.f.  tube  equivalent  resistance 
at  the  grid  of  the  r.f.  amplifier  would  be  the  controlling 
factor  in  noise  production. 

Another  error,  which  is  in  some  ways  more  obvious,  is 
the  application  of  a.v.c.  voltage  to  the  grid  of  the  2nd  r.f. 
amplifier  cathode  follower  in  Fig.  1  of  the  article.  If  A  is 
the  gain  of  the  tube  in  a  normal  grounded-cathode  amplifier 
application,  then  the  gain  of  a  cathode  follower  is 

A'  =  A  -^  (H-  A) 

and  since  the  gain  of  a  6C4  is  about  10  or  12,  this  fraction 
would  be  in  the  neighborhood  of  12/13  or  about  0.92.  If 
the  gain  of  the  tube  were  reduced  to  }4  by  a.v.c.  action,  or 
to  a  gain  of  4,  then  the  cathode-follower  gain  would  be 
reduced  to  4/5  or  0.8.  This  is  not  my  idea  of  very  good  a.v.c. 
action,  since  it  would  result  in  a  reduction  of  gain  of  small 
percentage  for  a  large  value  of  a.v.c.  voltage.  A  more  prac- 
tical method  would  be  to  apply  the  a.v.c.  (or  even  better, 
partial  a.v.c.)  to  both  r.f.  and  mixer  grounded  grids, 
grounding  the  grids  for  r.f.  through  a  0.01-/if.  capacitor.  In 
my  receiver,  applying  no  a.v.c.  to  the  r.f.  stage  or  mixer 
resulted  in  severe  cross-modulation  in  the  presence  of  strong 
adjacent  signals,  particularly  on  the  broadcast  bands.  This 
was  eliminated  completely  upon  apphcation  of  J^  a.v.c. 
voltage  to  the  r.f.  and  mixer  grids  as  indicated  above. 

In  addition,  the  authors  quoted  a  transconductance  of 
11,000  for  the  triode-connected  6AC7.  However,  the  tube 
manual  gives  this  value  of  ffm  only  for  a  plate  voltage  of  150 
volts  and  a  cathode  bias  resistor  of  160  ohms.  Under  these 
conditions  the  plate  current  is  12.5  ma.,  and  this  results  in 
a  bias  of  —2.0  volts.  The  1500-ohm  cathode  resistor  used 
by  the  authors  in  Fig.  1  is  certain  to  result  in  a  smaller 
effective  value  of  ffm  for  the  operating  conditions,  producing 
a  smaller  gain,  and  more  important,  more  noise.  I  used  a 
cathode  resistor  of  700  ohms  in  both  6AC7  stages,  and  would 
have  used  a  smaller  value  if  the  gain  had  appeared  to  be 
insufficient.  There  should  be  no  difficulty  in  obtaining  suffi- 
cient driving  voltage  even  with  a  cathode  resistor  of  only

100  to  200  ohms,  because  of  the  low-impedance  output  of 
the  cathode  follower.  I  have  not  been  able  to  obtain  a  set 
of  characteristics  for  the  triode-connected  6AC7,  so  I  have 
no  idea  how  the  variation  of  plate  voltage  will  affect  the 
picture,  but  as  a  general  thing,  the  greater  the  bias  voltage 
applied,  the  less  the  transconductance. 

Another  small  point:  In  Fig.  1  of  the  article,  it  is  not 
necessary  to  provide  the  47-MMf-  coupling  capacitor  and  the 
47K  resistor  to  the  grid  of  the  cathode  follower  on  the  oscil- 
lator stage.  The  d.c.  level  at  the  cathode  of  the  oscillator  is 
not  sufficient  to  affect  the  operation  of  the  cathode  follower, 
being  only  a  few  millivolts;  compared  to  that  at  the  cathode 
of  the  cathode  follower  it  is  negligible.  Furthermore,  either 
the  Hartley  or  the  tickler-feed-back  oscillators  showTi  in 
Fig.  2  can  be  used  as  a  grounded-plate  oscillator.  The 
Hartley  circuit  is  so  shown  in  Fig.  2;  the  tickler  circuit  need 
only  be  changed  to  look  as  follows:

This  results  in  a  somewhat  simpler  arrangement  than 
that  shown  in  Fig.  2,  and  uses  about  three  components  less. 
This  is  the  oscillator  circuit  as  I  used  it  in  my  receiver.  It  is 
to  be  noted  that  the  polarity  of  the  feed-back  coil  must  be 
observed  —  the  end  previously  tied  to  the  plate  must  go  to 
ground  to  maintain  oscillations.  In  my  opinion  this  con- 
figuration results  in  a  more  nearly  constant  output  as  fre- 
quency is  varied,  due  to  the  slight  degeneration  inherent  in 
having  a  r.f.  potential  at  the  cathode.  In  addition,  the  signal 
is  not  taken  from  the  tank  circuit  of  the  oscillator,  which 
improves  the  isolation  somewhat. 

In  closing,  let  me  say  that  in  my  case  the  article  was 

very  timely  and  much  appreciated.  I  am  enclosing  a  sketch 

of  the  complete  front  end  on  my  HQ-120  as  it  now  is  wired.

,  .  .  Before  proceeding  with  individual  points  it  might 
be  well  to  examine  the  equation  for  the  noise  figure  of  the 
input  stage  of  a  system  as  given  by  Goldberg  ("  Some  Notes 
on  Noise  Figures,"  I.R.E.  Proceedings,  October,  1948).

(1) 


The  first  term  on  the  right  side  of  this  equation  gives  the 
effect  upon  the  noise  figure  of  a  load  upon  the  source  of 
voltage  when  tube  noise  is  disregarded.  Such  a  load  pro- 
duces noise  but  no  signal;  thus,  ii  R  "  Ri  this  term  in  the 
equation  is  2.  The  second  term  shows  the  effect  of  the  load 


upon  the  source  in  reducing  the  voltage  in  comparison  with 
the  noise  voltage  contributed  by  J?«,.  li  R  —  Ri,  the  second 
term  of  the  equation  becomes  iRt^/R. 

When  iE«,  is  about  the  same  in  value  as  fi  or  larger,  the 
second  term  is,  of  course,  larger  than  the  first  term  and  has 
a  greater  influence  on  F.  Under  these  conditions,  changing 
from  the  actual  antenna  to  a  dummy  may  cause  a  change 
in  R  which  could  swamp  out  the  effect  of  any  external  noise 
present  in  the  antenna. 

Now  let  us  consider  the  simple  test  prescribed  to  deter- 
mine whether  or  not  the  receiver  is  noisy.  If  we  take  the 
assumption  made  by  the  authors  that  we  are  operating  at  a 
frequency  where  external  noise  is  very  low,  there  is  no  reason 
that  substituting  a  dummy  antenna  for  a  real  antenna 
should  reduce  the  noise,  since  the  radiation  resistance  of 
the  antenna  certainly  would  not  have  a  temperature  greater 
than  that  of  the  dummy  resistance.  If  there  were  actually 
no  external  noise,  this  test  could  condemn  the  best  receiver 
that  could  be  built.  The  fact  that  very  few  amateurs  have 
the  equipment  to  measure  the  impedance  of  an  antenna  also 
makes  it  very  difficult  to  assess  the  reason  for  the  change 
in  noise  level  when  the  dummy  antenna  is  substituted  for 
the  real  antenna.  As  shown  above,  with  a  change  in  im- 
pedances between  the  two  it  is  quite  conceivable  that  the 
noise  level  could  increase  when  the  resistor  is  substituted 
for  the  antenna. 

As  mentioned  in  the  article,  a  low-noise-figure  receiver 
has  no  advantages  in  a  noisy  location,  so  another  simple 
test  can  be  prescribed  to  see  if  the  receiver  is  working  down 
to  the  local  noise  level.  The  receiver  should  be  set  to  a  fre- 
quency where  there  are  no  signals  and  the  antenna  trimmer 
should  be  tuned  through  resonance.  If  there  is  an  increase 
in  noise  as  the  antenna  circuit  goes  through  resonance,  the 
receiver  is  satisfactory  for  the  location.  If  no  noise  peak  is 
noticed  then  some  improvement  is  called  for. 

If  we  are  to  make  some  improvement  in  the  receiver  it 
is  nice  to  know  where  to  begin.  Now  we  remove  the  antenna 
and  swing  the  antenna  trimmer  through  resonance.  If  we 
hear  the  noise  peak  there  is  hope  that  the  necessary  changes 
will  not  be  too  drtistic.  Perhaps  in  tliis  case  a  new  r.f.  ampli- 
fier may  be  the  answer.  If  we  hear  no  change  in  noise,  the 
next  step  is  to  vary  the  trimmer  on  the  next  grid.  If  a  change 
of  noise  is  heard,  there  is  still  hope  that  the  receiver  can  be 
improved.  If  no  change  of  noise  is  heard  in  this  case,  I  can 
only  recommend  a  new  receiver  or  a  converter. 

Assuming  that  we  have  decided  that  we  need  a  new  r.f. 
amplifier,  let  us  look  into  the  question  of  what  is  the  best 
type  of  amplifier  to  use.  To  make  our  calculations  easier, 
assume  that  we  match  the  antenna  into  the  receiver,  a  con- 
dition which  is  necessary  if  we  are  to  have  a  flat  transmission 
line  feeding  the  receiver.  Because  of  tracking  difficulties 
most  receivers  covering  wide  tuning  ranges  will  not  be  more 
closely  coupled  than  a  matched  condition.  This  matched 
condition  will  give  us  a  noise  factor  at  least  3  db.  worse  than 
we  would  have  if  we  had  no  loss  in  the  antenna  transformer 
and  maintained  the  same  source  impedance  feeding  the  tube. 

We  should  now  look  again  at  equation  (1). 

As  stated  by  Goldberg,  we  should  take  the  sum  of  the 
ffeqi  -|-  /feq2  for  the  two  tubes  in  a  cathode-coupled  circuit. 
For  simplicity,  lat  us  neglect  the  two  cathode  resistors  in 
the  circuit,  which  will  further  degrade  the  noise  performance 
of  the  amplifier,  and  just  assume  that  if  there  is  a  close 
contest  between  the  cathode-coupled  amplifier  and  one  of 
the  others,  it  would  be  advisable  to  select  the  other  one. 
Although  the  authors  have  selected  the  6AC7  as  a  high  gm 
tube  they  have  proceeded  to  bias  it  until  the  gm  is  down  to 
about  4000  /xmhos. 

In  our  calculations  let  us  consider  two  receivers,  one  with 
a  very  good  input  circuit  which,  when  loaded  by  the  an- 
tenna, offers  a  source  impedance  R  of  5000  ohms  to  the  r.f. 
amplifier  and  the  other  a  relatively  poor  one  which  offers 
a  source  impedance  of  500  ohms  to  the  first  tube.  We  can 
now  look  into  the  noise  figures  of  four  different  amplifiers: 
a  6SK7,  a  6AG5,  the  cathode-coupled  stage  recommended 
in  the  article,  and  a  6BQ7  cascode  circuit.  The  noise  re- 
sistances for  these  follow: 

6SK7  11,000  ohms 

6AG5  1650  ohms 

604  800  ohms 

6AC7  triode  with  1500-ohm  cathode  resistor    600  ohms 

6BQ7  500  ohms 

Goldberg  gives  the  following  formulas  for  the  noise  figures:

From  these  figures  it  can  be  seen  that  very  little  is  gained 
by  going  to  a  sj^stem  more  sophisticated  than  the  6AG5 
pentode  unless  R  is  very  low  and  in  this  case  it  seems  worth 
going  to  the  cascode  which  is  really  a  simpler  modification 
than  the  one  recommended  in  the  article  in  question. 

On  the  basis  of  the  considerations  above,  I  recommend 
that  anyone  contemplating  the  modification  of  a  receiver 
give  the  situation  a  lot  of  study  before  he  digs  in  with  the 
cutting  pliers;  and  it  is  my  opinion  that  the  modifications 
recommended  in  the  article  are  not  the  easy  way  to  improve 
a  receiver.

Whilst  the  writer  can  fully  agree  in  principle  with  the 
findings  of  Longerich  and  Smith  in  their  article  on  low- 
noise  receiver  design,  it  seems  that  they  have  taken  the  long 
way  round  the  problem. 

The  6J6  has  an  equivalent  noise  resistance  of  470  ohms,' 
and  lends  itself  to  use  in  the  circuit  shown  in  Fig.  1,  which 


R.F.  AMP 


is  electrically  identical  to  that  used  by  your  contributors 
in  their  r.f.  stages.^ 

One  of  the  advantages  of  this  circuit  is  its  ability  to  handle 
signals  of  several  volts;  yet  it  is  reasonably  free  from  cross- 
modulation  effects.  This  is  because  the  total  plate  current 
is  almost  constant  when  the  control  voltage  is  varied.  For 
example,  a  drop  in  the  grounded-grid  section  plate  current 
caused  by  a.v.c.  lowers  the  bias  to  the  cathode-follower 
section,  which  in  turn  increases  the  plate  current  in  that 
section.  It  follows  then  that  the  cathode-follower  section 
is  unimpaired  by  a.v.c.  bias  and  may  handle  a  signal  input

of  several  volts.  The  degree  of  curvature  of  the  grounded- 
grid  section  then  determines  the  degree  of  cross-modulation. 
The  stage  gain  compares  more  than  favorably  with  ordinary 
r.f.  pentodes,  and  it  may  have  a.v.c.  applied. 

Mixer  tracking,  instability  and  oscillator  pulling  diffi- 
culties experienced  by  the  authors  were  to  be  expected  under 
the  conditions  of  nonisolation  used.  A  mixer  capable  of  good 
gain  (approximately  14  times  at  30  Mc.)  with  quiet  opera- 
tion is  shown  in  Fig.  2.^  This  circuit  has  good  isolation  from 
the  oscillator.  Circuit  gain  is  independent  of  oscillator  in- 
jection-voltage change. 

An  alternative  oscillator  to  that  used  by  the  authors  is 
shown  in  Fig.  3.  This  circuit  overcomes  switching  difficulties

since  there  is  no  cathode  tap  nor  are  there  two  coils  to  switch 
as  in  pentagrid  circuits.  The  cathode  output  gives  splendid 
isolation  from  the  mixer  and  puUing  troubles  are  virtually 
eliminated. 

Feed-back  control  is  by  means  of  Ci,  which  should  be  a 
silver  mica  for  best  stability.  The  value  shown  for  Ci  is 
satisfactory  for  operation  over  the  range  3.5  to  50  Mc,  but 
for  operation  at  i.f.  requires  a  feed-back  condenser  value  of 
100  nii(.  or  larger,  depending  on  the  i.f.  This  circuit  makes  an 
excellent  b.f.o.,  since  any  old  i.f.  transformer  will  sufi&ce  for 
the  grid  inductance,  no  tap  being  required.  All  these  circuits 
have  been  tried  and  are  in  use  in  the  writer's  receiver.  They 
are  simple  to  adapt  into  existing  commercial  receivers,  re- 
quiring only  a  socket  change  and  realignment.  Manufac- 
turers seem  to  have  overlooked  these  triode  circuits,  and 
it  would  be  worth  their  while  to  experiment  with  them.

In  the  March  issue  of  QST  Longerich  and  Smith  discuss 
low-noise  receiver  design.  The  r.f.  input  circuit  shown  is  a 
cathode-follower  amplifier  followed  by  a  grounded-grid 
stage.  I  believe  their  interpretation  of  the  performance  of 
this  combination  is  somewhat  misleading,  in  that  it  seems 
that  they  assume  that  the  low-noise  performance  of  the 
grounded-grid  amplifier  is  not  spoiled  by  the  preceding 
cathode  follower,  or  grounded-plate  ampUfier,  and  in  fact, 
no  thought  seems  given  to  the  choice  of  a  triode  of  low- 
noise  resistance  for  the  cathode-follower  stage,  since  a  Type 
6C4  tube  is  used.  The  noise  resistance  of  a  6C4  is  1140  ohms 
compared  with  220  ohms  for  a  triode-connected  6AC7.  The 
combination  used  by  the  authors  would  be  somewhat  in- 
ferior to  a  low-noise  design  using  a  single  pentode-connected 
grounded-cathode  ampUfter  employing  a  Type  6AC7  tube. 

Basically,  the  circuit  used  by  the  authors  is  a  grounded- 
plate  grounded-grid  triode  amplifier.  The  conventional  cir- 
cuit is  (simplified) :

new  diagrams,  and  help  us  over  the  transition  period.  We 
all  would  then  concentrate  more  on  the  diagrams  and  less 
on  the  text,  and  thus  more  easily  learn  the  new  and  forget 
the  old. 

Of  course  I  am  not  really  serious  as  I  can  see  the  ad- 
vantages of  standardization,  although  it  is  rather  bitter 
to  take  in  one  gulp.

.  .  .  Maybe  the  alphabet  should  be  revised  too.  It  too 
has  a  lot  of  little  loop  holes  to  fill  up  with  ink  like  the  old 
coil  symbol.  Wonder  how  many  of  those  responsible  actually 
use  the  "New  Look"  in  their  daily  sketches?  My  soldering 
iron  didn't  get  much  work  out  from  the  past  two  issues  of 
QST.  But,  I  suppose  in  due  time  we  will  all  get  accustomed 
to  it.  It  is  about  time  the  different  branches  of  the  elec- 
tronics industries  standardized  in  their  svmbols.

THIRD-PARTY  TRAFFIC 

51  Pettits  Lane 
Romford,  Essex,  England 
Editor,  QST: 

After  reading  the  letter  from  WIDLO  on  the  above  sub- 
ject in  May  QST,  I  feel  that  I  ought  to  correct  a  widespread 
misunderstanding  regarding  G  stations.  We  are  not  allowed 
to  accept  or  originate  third-party  messages  in  any  shape 
or  form  as  laid  down  by  our  license  conditions,  and  any 
station  so  doing  is  liable  to  receive  the  G  equivalent  of  a 
pink  ticket  by  return  of  post. 

In  the  past  I  have  heard  W  stations  calling  specific  cities 
in  this  country  and  saying  that  they  have  traffic.  They 
have  probably  been  disappointed  in  not  receiving  a  reply, 
and  I  hope  the  true  reason  will  be  appreciated. 

While  on  the  subject  of  trafiic,  may  I  enter  a  plea  for  the 


removal  outside  the  ham  bands  of  the  MARS  stations  in 
Europe  and  Africa  who  clutter  up  our  frequencies  with  high- 
power  stations  passing  military  traffic  only.  These  messages 
generally  relate  to  movement  of  personnel  and  supphes, 
etc.  The  stations  use  amateur  call  signs  and  are  prevalent 
on  the  20-meter  band.  In  Europe  we  suffer  enough  com- 
mercial QRM  on  this  band  without  this  addition,  and  I 
woiild  have  thought  that  the  operators,  who  appear  to  be 
hams,  would  have  appreciated  this  fact.  Presumably, 
however,  this  operation  has  oflScial  backing.

.  .  .  -Although  I  could  write  a  great  deal  pertaining  to 
flag  waving  and  sentiment,  I  feel  it  would  have  little  effect 
on  the  FCC.  I  can  fully  understand  the  need  for  the  law; 
however,  I  cannot  see  why  it  should  pertain  to  military 
personnel. 

All  DL4  stations  are  U.  S.  military  persoimel.  Although 
the  licenses  are  issued  by  the  German  government,  all 
exams  are  given  by  U.  S.  military  officers,  all  stations  are 
located  on  property  controlled  by  the  U.  S.  government,  and 
the  majority  of  the  equipment  is  owned  by  the  U.  S.  govern- 
ment. This  certainly  makes  us  controlled  more  by  the  U.  S. 
government  than  most  parties  listed  as  free  to  handle 
third-party  traffic. 

The  majority  of  the  DL4s  are  MARS  operators  and  just 
about  all  the  operating  is  done  from  MARS-controlled 
stations.  However,  there  is  only  one  M.\RS  frequency  on 
which  conditions  and  power  permit  us  to  reach  the  States. 
This  is  hardly  enough  to  handle  priority  traffic  (pertaining 
to  deaths  or  serious  illnesses)  much  less  normal  traffic. 

I  would  certainly  appreciate  you  giving  our  side  of  the 

situation  the  same  consideration  you  gave  the  opposite  side.

LEVELING  PROCESS 

19  Pa  ton  Street 
Piccadilly,  Manchester  1 
England 
Editor,  QST: 

I  read  with  disappointment  the  letter  from  one  of  our 
fellow  Gs  on  the  subject  of  QRP  (April  QST). 

What  he  says  may  be  true  of  a  certain  type  of  ham; 
one,  say,  who  believes  in  bringing  everyone  in  every  way 
down  to  his  level.  But  it  must  not  be  imagined  that  we 
all  feel  like  that.  Some  of  us  are  very  tired  of  this  leveling- 
down  process  we  are  subjected  to  over  here,  and  would  hate 
to  see  it  applied  where  it  does  not  exist  in  other  countries. 

Our  friend's  suggestion  of  a  general  limitation  to  150 
watts  does  not  seem  to  me  to  offer  any  solution  to  his 
complaint,  and  even  if  this  was  the  case,  some  would  get  out 
better  than  others,  and  there  would  still  be  the  same  number 
of  stations.  I  suppose  he  would  then  start  a  campaign  for 
half-wave  dipoles  only  to  be  used. 

Finally,  if  some  brother  ham  wants  to  spend  some  of  his 
money  on  a  bigger  and  better  rig,  I  say  good  luck  to 
him.  .  .  .

QST- Volume  IV 


Part  I ^  —  Foreword  to  Sumner  B.  Young's  (W0CO)  Index 


VOLUME  IV  of  QST  was  the  second  com- 
plete Volume  to  be  published  under  the 
management  of  a  full-time  editor  (the  late 
K.  B.  Warner).  It  was  issued  during  the  period 
August,  1920,  to  July,  1921,  inclusive. 

Volume  III  of  QST  had  been  a  big  one,  as 
readers  of  my  index  will  have  seen;  but  Volume 
IV  was  to  surpass  it,  both  in  size  and  importance. 

As  a  "background"  for  Volume  IV,  let  us  re- 
view some  of  the  events  covered  by  Volume  III. 

A  great  "boom"  in  amateur  activities  had 
followed  restoration  of  transmitting  privileges  in 
October,  1919.  Amateurs  had  begun  flocking  to 
local  and  regional  meetings.  On  a  small  scale, 
"tube"  transmission  had  begun;  and  the  new 
editor  had  encouraged  it  enthusiastically.  A  few 
progressive  amateurs  had  "taken  up  c.w."  de- 
spite the  coolness  toward  it  which  many  friends 
of  the  spark  transmitter  had  instantly  displayed. 
With  the  advent  of  Volume  IV,  the  groundwork 
for  further  progress  in  this  (and  other)  fields  had 
been  accomplished. 

One  of  the  most  interesting  items  in  Volume 
IV  is  an  editorial  published  in  the  September, 
1920,  issue  ("In  Introspect"),  which  contains  a 
review  and  an  evaluation  of  the  happenings  of 
the  previous  twelve  months.  As  of  that  date, 
it  was  Mr.  Warner's  opinion  that  during  the 
first  year  of  amateur  work  following  the  restora- 
tion of  transmitting  privileges  in  October,  1919, 
the  development  of  "tube"  transmitters  had 
constituted  our  most  significant  achievement. 
Despite  the  difficulties  of  obtaining  power 
tubes  (not  yet  placed  on  the  amateur  market), 
and  regardless  of  the  expense  of  producing 
suitable  high  voltage  power  suppUes  for  the 
plate  circuits,  the  "pioneers"  had  done  the  job. 
Some  of  them  had  held  Special  or  Experimental- 
Station  Ucenses,  and  could  lawfully  operate  on 
wavelengths  around  300  to  350  meters  —  which 
was  a  distinct  advantage,  because  most  of  the 
early  c.w.  transmitting  circuits  (a  term  loosely 
applied  to  c.w.,  i.c.w.,  and  'phone  arrangements) 
would  not  operate  below  300  meters.  Others,  who 
had  held  only  General  amateur  station  licenses 
officially  Umiting  them  to  waves  not  exceeding 
200  meters,  had  also  participated  in  this  early 
work  (with  or  without  a  special  permit) ;  but  the 
Department  of  Commerce  had  been  indulgent; 
and,  in  any  event,  it  had  lacked  sufficient  per- 
sonnel and  financial  appropriations  to  enable  it 
to  "crack  down",  even  if  it  had  wanted  to 
do  so.  Nobody  had  paid  much  attention  to  the 
200-meter  restriction,  even  in  the  case  of  spark

ruary. 1956;  Part  I  of  "QST  —  Volume  III,"  March,  1955;

stations;  and  (in  1920-1921)  the  over-all  average 
amateur  wavelength  in  actual  use  was  at  least 
240  meters.  (See  Warner's  editorials,  at  31-32, 
January  1921,  and  at  25,  April  1921.) 

Volume  IV  of  QST  records  some  significant 
events  occurring  in  the  c.w.  field:  (1)  In  the 
Spring  of  1921,  the  R.C.A.  power  tubes  arrived. 
The  famous  "5-watter"  (the  UV  202)  was 
first  released.  Then  came  the  very-popular  "50- 
watter"  (the  UV  203),  and  the  announcement 
that  larger  tubes  (not  so  important  to  the 
widespread  development  of  the  art,  as  it  turned 
out)  would  be  released  in  fall  of  1921.  (2)  P.  J. 
Furlong's  article  on  the  electrolytic  rectifier  waa 
published.  (3)  E.  W.  Whittier's  article  gave 
data  on  the  famous  "IDH"  c.w.  circuit  (also 
called  the  "sure-fire  c.w.  circuit",  the  "reversed- 
feedback  circuit",  the  "Stanley  circuit"  and 
the  "British-aircraft  circuit").  And  (4)  John 
Reinartz  published  his  memorable  article  on  his 
"C.  W.  Tuner". 

Events  (3)  and  (4),  in  the  above  fist,  showed 
amateurs  how  to  operate  "tube"  transmitters 
on  200  meters,  or  on  wavelengths  even  below 
200;  and  they  also  taught  them  how  to  receive, 
and  to  hold,  a  c.w.  signal  over  a  wide  range  of 
wavelengths.  As  a  result,  more  tube  sets  went 
into  operation,  down  below  300-350  meters. 

Another  characteristic  of  the  busy  and  event- 
ful months  covered  by  Volume  IV  of  QST,  was 
this:  Hams  had  become  so  numerous,  that  some 
means  of  controlling  their  own  "use  erf  the  air" 
had  become  imperative.  Almost  everybody  was 
operating  at  about  the  same  wavelength  (240 
meters;  not  at  the  legal  maximum  of  200  meters, 
or  below  it) .  Spark  transmitters  —  notorious 
"QRM-producers"  —  were  still  the  most  widely 
used  type  of  rig.  Practically  none  of  the  c.w. 
stations  were  using  "pure  c.w."  (see  57,  July 
1921);  and  the  radiophones  created  so  much 
interference  that  one  expert  (Kruse)  reached  the 
conclusion  that  as  far  as  he  was  concerned  they 
were  "an  obnoxious  perversion  of  the  c.w.  set". 
(57,  July  1921). 

The  resulting  din  in  the  ether  was  terrific. 

Note  that  this  QRM  situation  was  still  very 
largely  an  amateur  affair.  It  is  true  that  some 
broadcast-listeners  (BCLs)  had  also  arrived  on  the 
scene;  but  the  great  public  "rush"  to  equip  one's 
home  for  the  reception  of  broadcast  programs  did 
not  get  under  way  until  fall  of  1921. 

The  principal  method  of  resolving  this  particular 
problem  was  quickly  developed.  It  was  the  so-called 
"Chicago  Plan",  originated  by  F.  H.  Schnell  and 
R.  H.  G.  Mathews,  and  sponsored  and  adminis- 
tered, originally,  in  the  Chicago  area,  by  the  Chicago 
Executive  Radio  Council.  A  time  schedule  was 
agreed  upon,  and  enforced.  Different  classes  of 


50 


QST  for 


amateur  radio  communication  were  allotted  a 
place  on  the  schedule;  and  (for  a  while  at  least), 
great  improvement  in  operating  conditions  was 
achieved.  This  plan  depended  upon  the  organiza- 
tion of  strong  clubs  —  particularly  near  large 
centers  of  population.  It  had  the  outstanding 
merit  of  providing  an  essential  function  for 
those  clubs  to  perform;  and,  for  that  reason,  it 
tended  to  develop  a  fine  group  of  local  and 
regional  organizations  affiliated  with  the  League. 

The  "Chicago  Plan"  spread  rapidly  over 
the  U.  S.  A.  But  when  (at  a  later  period  of 
time)  the  problems  connected  with  BCI  became 
so  numerous  and  so  serious  that  amateur  radio's 
very  existence  was  endangered,  this  scheme 
proved  to  be  inadequate.  (We  shall  see,  later, 
when  we  examine  Volume  V  of  QST,  that  at- 
tempts to  bring  the  BCLs  into  the  amateur 
clubs,  and  to  make  these  listeners  parties  to  any 
agreements  about  "use  of  the  air,"  were  hopeless; 
and  that  only  technological  solutions  were  of  any 
avail.)  It  is  true  that  even  back  in  the  period 
extending  from  August,  1920,  to  July,  1921, 
some  of  the  more  far-sighted  amateurs  suggested 
that  the  development  and  use  of  waves  below  200 
meters  was  imperative,  from  the  standpoint  of 
QRM  avoidance.^  Unfortunately,  their  views 
were  Uttle  noticed.  But,  "for  the  record,"  I 
wish  to  draw  your  attention  to  three  items:  (1) 
The  work  of  Professor  R.  V.  Achatz,  City  Man- 
ager in  Lafayette,  Indiana :  ^  (2)  A  remarkable 
letter  from  F.  B.  Llewellyn;  '  and  (3)  An  instruc- 
tive and  well-reasoned  letter  from  W.  F.  Scott 
(2PP).'« 

The  period  with  which  Volume  IV  of  QST 
deals  was  also  characterized  by  other  problems. 
One  concerned  allotment  of  wavelengths  below 
WO  meters  at  a  time  before  the  full  usefulness 
of  such  waves  had  been  even  faintly  proved: 


a  series  of  attempted  "grabs"  by  the  U.  S. 
Navy  conunenced."  Another  involved  the  as- 
signment of  wavelengths  around  300  meters: 
the  A.T.&T.  wanted  these  for  use  in  shij>to- 
shore  telephony.'  Editor  Warner  thoughtfully 
sounded  the  warning  that  it  was  necessary  for 
the  radio  art  to  develop  every  single  wavelength 
which  could  be  put  to  practical  u^e.''  How  many  of 
us  paid  attention,  I  do  not  know. 

Closely  aUied  with  wavelength  allocation  prob- 
lems were  activities  in  the  legislative  field. 
With  the  rise  of  broadcasting,  and  the  develop- 
ment of  interest  in  short  waves  as  a  potential 
source  of  many  communication  channels,  the 
old  Radio  Act  of  1912  had  begun  to  "break 
down."  It  did  not  confer  upon  the  Secretary  of 
Commerce  adequate  means  and  discretion,  in 
the  matters  of:  the  classification  of  radio  stations, 
the  prescription  of  the  services  which  they  should 
perform,  and  the  specification  of  the  frequencies 
upon  which  they  should  operate.  He  even  lacked 
power  to  deny  a  request  for  a  broadcasting 
station  license  which  actually  (from  the  stand- 
point of  pubUc  interest,  convenience,  or  necessity) 
would  clearly  be  improvident  to  issue.  Although 
the  first  of  the  so-called  "National  Conferences" 
between  representatives  of  the  radio  industry 
and  various  governmental  agencies  was  not 
held  until  February  27,  1922,^  Secretary  Herbert 
Hoover  (at  an  earlier  date  —  in  1920)  named 
a  committee  to  recommend  a  new  radio  law  "to 
meet  modem  conditions";  and  he  appointed 
Mr.  Charles  H.  Stewart  (of  St.  David's,  Penn- 
sylvania) to  serve  on  it  as  the  League's  represen- 
tative.^ In  1920,  this  committee,  "consisting  of 
representatives  from  every  radio  interest  in  the 
country"  gave  consideration  to  the  question: 
What  should  be  the  amateur's  wavelength 
assignment  in  the  new  law  to  be  recommended 


^  In  fact,  suggestions  to  this  effect  had  been  made  as  far 
back  as  October,  1919.  See  26  to  27,  October  1919.  Other 
references:  20,  January  1920;  17  to  18,  February  1920; 
13  to  14,  February  1920;  40,  December  1920;  and  35, 
November  1920. 

*  44,  June  1921.  This  is  an  item  under  "Strays,"  and 
reads:  "We  are  proud  of  the  city  of  Lafayette,  Indiana. 
Professor  R.  V.  Achatz  of  Purdue  University,  City  Manager, 
reports  he  has  his  city  tuned  down  to  200  meters,  and  has 
personally  checked  up  every  station  under  his  jurisdiction, 
with  several  of  the  smaller  stations  operating  on  160  and  180 
meters.  Let's  have  more  cities  like  Lafayette."  (Italics  by 
S.B.Y.) 

*  59,  64,  January  1921.  This  letter  points  out  the  great 
difficulties  to  be  faced  in  attempting  to  eliminate  inter- 
ference by  time-schedules,  and  then  says:  "...  The  new 
plan  is  taken  from  Naval  procedure. 

"The  idea  is  based  on  a  change  of  wavelength.  A  desig- 
nated wave  is  fixed  on  which  all  calling  shall  be  done.  Other 
wavelengths  are  arranged  so  that  once  having  established 
communication,  it  is  a  simple  matter  to  shift  to  a  wavelength 
on  which  there  is  no  interference.  .  .  . 

"The  amateur  is  limited  to  200  meters.  During  the  war 
the  Navy  used  a  wavelength  of  52  meters  for  short  distance 
work.  Amateurs  whose  powers  do  not  exceed  }4  k.w.  could 
use  100  meters  or  less  without  a  very  appreciable  decrease 
in  range.  They  would  then  be  free  from  jamming  by  higher 
powered  amateur  stations. 

"  Each  higher  powered  station  should  he  tuned  to  a  slightly 
different  wave  under  SOO.  It  would  not  be  diflScult  to  have 
these  waves  published  in  the  call  books. 

"Under  these  circumstances  a  common  calling  wave 
would  not  be  necessary  .  .  ."  (Italics  by  S.B.Y.) 


*  55  to  56,  December  1920.  Scott  described  and  dia- 
grammed a  tuned  spark-coil  set,  using  a  Century  buzzer 
as  an  independent  interrupter,  giving  a  good  500-cycle  note. 
Means  of  bringing  the  primary  circuit  of  the  spark  coil  itself 
into  resonance  with  the  frequency  of  the  buzzer,  by  means  of  a 
large  choke  having  a  sliding  metal  core,  were  disclosed.  This 
transmitter  covered  10  to  20  miles,  with  an  input  of  8  to 
10  Watts,  on  "200  meters."  The  letter  then  states:  "... 
With  the  same  set  using  a  smaller  condenser  and  a  loading 
coil  in  the  open  circuit,  signals  have  been  transmitted  about 
a  mile  on  a  portion  of  the  lead-in  25  ft.  long  and  20  ft. 
high.  The  wave  used  was  about  180  meters.  Good  radiation 
was  obtained  but  very  few  sets  in  the  vicinity  were  able  to 
get  down  to  some  of  the  low  waves  used. 

"  Through  these  experiments  I  believe  it  is  entirely  possible 
for  amateurs  to  have  a  small  indoor  aerial  for  work  on  waves 
as  low  as  100  meters  and  with  which  local  communication  could 
be  carried  on  successfully,  thus  eliminating  some  of  the  QRM 
on  200."  (Italics  by  S.B.Y.) 

^33,  July  1921.  This  editorial  indicates  that  the  Navy 
wanted  a  wavelength,  down  below  the  suggested  amateur 
wavelength  assignments,  for  "chaser  boats." 

«33,  July  1921.  The  editorial  "What  We  Want  in  Radio 
Law,"  here  cited,  states:  "...  with  the  Navy  below  us 
and  the  A.T.&T.  above  us,  both  clamoring  for  more  room, 
believe  us,  we  would  like  to  see  our  wavelength  written  into 
the  law  so  that  there  would  be  no  question  about  it.  .  .  ." 

^  33,  July  1921.  " .  .  .  the  intensive  development  of  radio 
demands  that  use  be  made  of  all  waves.  ..."

by  the  conferees?  The  iiiisvver  was  this:  180 
to  220  meters,  for  spark  stations,  and  180  to  250 
meters  for  c.w.  stations.'" 

As  of  June,  1921,  no  less  than  seven  radio  bills 
were  pending  in  Congress.^'  The  most  "unpalata- 
ble "  of  these  was  "Senator  Poindexter's  infamous 
S.  31."  '^  Offsetting  this,  was  Congressman 
White's  Bill,  H.R.  4132.1'  An  ARRL  "legislative 
committee"  was  watching  developments;  and 
Secretary  Warner  visited  Washington  to  gather 
information  and  to  report  his  findings. '* 

The  June,  1921,  issue  of  QST  also  mentions 
the  fact  that  the  Department  of  Commerce  had 
sent  a  representative  to  Paris  in  the  year  1920 
to  attend  a  preliminary  international  conference; 
and  that  the  report  prepared  at  that  gathering 
was  "already  influencing  practice  in  the  choice 
of  wavelengths,  in  the  classification  of  modern 
types  of  radio  systems,  etc."  '^ 

The  period  of  time  reflected  in  Volume  IV  of 
QST  was  also  marked  by  the  rise  of  the  big 
conventions.  These  eventually  were  to  lead  to  a 
National  Convention,  at  Chicago,  in  September, 
1921.  The  large-scale  affairs  held  at  Philadelphia, 
St.  Louis,  New  York,  San  Francisco,  and  Chicago, 
were  the  most  noteworthy.  ^^ 

In  this  same  period,  amateurs,  in  cooperation 
with  the  U.  S.  Bureau  of  Standards,  participated 
in  several  series  of  so-called  "fading  tests",  in  an 
attempt  to  discover  the  causes  of  fading. 

First  transmissions  were  on  250  meters.  Some 
later  transmissions  were  made  on  200  meters. 
Both  spark  and  tube  transmitters  were  used. 

The  scientific  results  were  not  of  great  im- 
portance; but  the  several  series  of  tests  repre- 
sented an  outstanding  example  of  amateur  co- 
operation with  government  agencies. 

In  the  April,  1921,  "fading  tests,"  one  station 
(9ZN,  at  Chicago)  operated  two  transmitters, 
simultaneously,  on  200  meters;  3XF  and  NSF 
were  "on  the  air,"  at  the  same  time  (on  200), 
with  i.c.w.  sets;  and  9LQ  and  9JZ  transmitted 
(on  200),  at  the  same  time  using  synchronous- 
spark  transmitters.  1^ 


Other  cooperative  activities  involved  the  use 
of  amateur  stations  to  disseminate  poHce,  Mar- 
ket-Bureau, and  Weather-Bureau  reports  and 
information.  A  report  received  (from  KUVS)  by 
Messrs.  Richard  Frank  and  William  Mitchell, 
who  operated  station  2TK,  at  Union  Hill,  N.  J., 
resulted  in  the  recovery  of  the  first  "hot"  car  to 
be  located  with  amateur  help.  This  was  about 
March  21,  1921. '^ 

With  the  increased  use  of  radiotelephone  trans- 
mitters, in  particular,  amateur  stations  began  to 
be  used  for  broadcasting,  and  for  other  purposes 
which  have  long-since  been  declared  illegal. '^ 
(When  we  study  Volume  V,  of  QST,  we  shall  see 
some  of  the  consequences  of  the  indiscriminate 
use  of  poorly  operated  amateur  radiophone 
stations. ) 

The  spark  transmitter  was  still  a  favorite, 
with  most  amateurs;  and,  in  fact,  some  of  the 
DX  records  held  by  such  stations  as  2BK, 
2RK,  6JD,  and  9ZN,  were  "mighty  impressive." 

2BK  was  heard  in  Los  Angeles,  by  6KA,  on 
April  19,  1921,  at  about  4:38  a.m.  (EST).20  The 
world  records  of  2RK  (J.  K.  Hewitt,  of  Brooklyn, 
N.  Y.),2i  listed  on  page  43  of  the  February,  1921 
issue,  included  the  following  items:  (a)  Decem- 
ber, 1920  —  copied  by  an  American  ship,  from 
New  York  to  London  and  return;  (b)  Copied  on 
a  Grebe  CR-6  receiver,  by  an  English  vessel,  at 
Gibraltar  (3,200  miles);  nd  (c)  Reported  heard 
off  Pernambuco,  South  America,  on  a  Navy 
SE-1420  (non-regnerative)  receiver,  a  distance  of 
3,600  miles. 

Stations  6JD,  9ZN,  and  lAW,  "hung  up"  a 
new  record  for  a  round-trip  "transcon"  message, 
on  the  night  of  January  17th-18th,  1921,  when 
they  handled  one  "over  and  back,"  in  63^ 
minutes.^^ 

DX  work,  and  large  scale  message  handling, 
with  various  types  of  tube  transmitters  also  be- 
gan to  be  reported.  These  reports  were  impres- 
sive, largely  for  the  reason  that  the  power  of 
most  c.w.  stations  (as  of,  say,  July,  1921)  was 
under  50  watts.^^  Station  2ZM  was  heard  (on

QST  for 


325  meters)  by  a  ship  in  the  Pacific  Ocean,  lo- 
cated off  Guatemala,  Central  America.^*  Frank 
Conrad's  station,  8XK  (in  Pittsburgh),  which 
used  an  "r.a.c."  plate  supply,  was  heard  3,000 
miles  away.^^  And  on  the  night  of  July  10th, 
1920,  a  non-amateur  station,  NSF,  using  two 
250-watt  tubes,  and  an  Alexanderson  multiple- 
tuned  antenna,  was  heard  in  Bristol,  England.^^ 
With  records  like  these  before  them,  it  was  only 
natural  that  amateurs  should  speculate  on  the 
possibility  of  bridging  the  Atlantic,  by  means  of 
amateur  transmitters;  and  (in  February,  1921), 
the  first  "transatlantic  tests"  were  run.  These 
were  hastily  organized  and  were  not  properly 
planned.  In  any  event,  the  tests  failed;  and  per- 
haps their  principal  value  was  to  disclose  certain 
defects  of  planning  and  of  preparation  which  the 
"second  transatlantics"  avoided.  (The  story  of 
those  second  tests  is  covered  in  Volume  V  of 
QST.) 

In  the  May  (1921)  issue  of  QST,  Mr.  Warner 
(at  page  16)  made  the  interesting  announcement 
that  he  would  bet  his  new  spring  hat  that  if  a 
good  U.  S.  amateur  were  sent  to  England  with  a 
standard  American  regenerative  receiver  (using 
variometer  tuning  in  the  secondary  and  tertiary 
circuits),  and  with  an  Armstrong  superhetero- 
dyne, "reception  of  U.  S.  amateurs  would  straight- 
way become  commonplace."  (Italics  by  S.B.Y.) 

Volume  IV  also  records  the  results  of  the 
"Ideal  Relay  Sjjark  Transmitter  Contest."  This 
represented  the  first  orderl}'  and  systematic  at- 
tempt to  collect,  and  to  summarize,  the  learning 
which  amateurs  had  acquired  on  any  one  subject. 
By  the  time  when  the  findings  were  published, 
however,  the  "shift-over"  from  spark  to  c.w.  had 
acquired  considerable  momentum:  and  amateur 
spark  transmitters  had  only  a  short  time  to  live. 

Emergency  and  relief  work,  by  amateur  sta- 
tions, during  the  period  covered  by  Volume  IV 
of  QST,  was  almost  nil.  Gushing,  of  Duxbury, 
Mass.  (IFBF)  performed  the  most  noteworthy 
work  within  this  category:  On  November  28, 
1920,  the  U.  S.  Minesweeper  Swan  went  ashore, 
near  that  place,  in  a  terrific  northeast  gale.  She 
was  unable  to  "raise"  the  Boston  Navy  Yard, 
on  her  radio;  so  Gushing  relayed  her  traffic  to 
KQZ  (S.S.  City  of  Rome).  She,  in  turn,  passed  it 
on  to  NAD.  (The  crew  of  the  Swan  was  rescued.) 

The  best  "reminiscences"  published  in  Volume 
IV  were  those  written  by  Irving  Vermilj^a,  con- 
cerning the  "passing"  of  old  WCC  (Gape  God). 
These  will  be  found  at  16  to  17,  August  1920. 

In  the  short-wave  field,  the  advent  of  John 
Reinartz's  "G.W.  Tuner"  provided  a  means  of 
receiving  waves  down  as  low  as  150  meters.^^ 


But  commercially-built  receivers  were  still  in- 
adequate for  reception  of  signals  below  200  me- 
ters. The  September,  1920,  issue  of  QST  re- 
ported 28  that  "old"  6KL  (William  Wood),  now 
Canadian  5BR  (of  Vancouver,  B.  C.)  was  trans- 
mitting on  100  meters,  with  H-k.w.  of  power, 
and  that  he  was  hoping  to  contact  some  U.  S. 
amateurs  in  the  7th  District.  (I  have  since  won- 
dered what  results  he  had  down  there.) 

The  November  (1920)  issue,  at  page  35,  an- 
nounced that  E.  A.  Bessey  (6BR,  of  Sunnyvale, 
California)  had  installed  "a  new  panel- type 
transmitter  designed  for  150,  200  and  375  me- 
ters"; and  it  stated  that  this  would  "greatly 
relieve  the  QRM  situation." 

At  page  40  of  the  December  (1920)  issue,  I  find 
that  John  D.  Hertz  (7ZB,  of  Portland,  Oregon) 
announced  that  he  would  do  local  work,  on  c.w.,  on 
150,  175,  and  200  meters.  (Again,  I  wish  I  knew 
what  the  results  of  his  work  turned  out  to  be.) 

Sunspots,  magnetic  storms,  and  Aurora-Bore- 
alis  effects  were  noted  by  various  amateurs.'-^ 

A  "dead-spot",  near  Savannah,  Georgia,  was 
explored  by  4YA.  He  arranged  tests  between  a 
radiophone  station,  mounted  in  a  truck,  and 
other  amateur  stations.^"  Two  other  "deadspots" 
—  between  Springfield  and  Boston,  Massachu- 
setts, and  between  Springfield  and  Worcester, 
Massachusetts  —  were  also  noted,  but  were  not 
explored.^'  The  Bureau  of  Standards  sought 
data  concerning  "dead-spots"  at  sea.'^ 

In  the  "miscellaneous"  category,  readers  of 
the  Index  to  Volume  IV  of  QST  will  be  inter- 
ested in  the  following  items: 

(a)  League  affairs: 

League  Officers  began  to  visit  hams  in  various 
parts  of  the  U.  S.  A.;  and  Mr.  Maxim  became  the 
first  League  officer  to  visit  amateurs  on  the  West 
Coast. ^^  While  in  San  Francisco,  he  made  an 
address  over  the  De  Forest  radiotelephone  sta- 
tion.^ 

F.  H.  Schnell  became  the  League's  first  full- 
time  Traffic  Manager.^* 

During  the  Midwest  Convention  at  St.  Louis, 
the  League's  Board  of  Directors  met  in  that  city; 
and  "for  the  first  time  our  directors  from  the 
west  and  south  actually  sat  in  with  those  from  the 
east  and  north."  ^® 

At  the  Pacific  Division  Convention,  in  San 
Francisco,  "the  question  arose  of  forming  a 
separate  relay  league  on  the  Pacific  Coast,  to  be 
entirely  independent  of  our  American  Radio 
Relay  League."  This  was  overwhelmingly  de- 
feated."

Results —  YL-OM  Contest 

The  Sixth  Annual  YL-OM  Contest  sponsored 
by  the  Young  Ladies  Radio  League  attracted 
more  YLs  and  OMs  than  ever  before.  Two- 
hundred  seventy-four  logs  were  received,  an 
increase  of  about  100  over  1954.  One  hundred 
sixty-eight  of  the  logs  came  from  OMs,  along 
with  such  comments  as: 

"Didn't  realize  there  were  so  many  fine  c.w.  operators — ■ 
and  so  patient  they  would  operate  at  any  convenient 
speed." 

"The  thrill  of  a  century  —  will  be  aboard  next  year." 
"Lots  of  fun  —  more  girls  on  c.w.  this  year." 
"Having   c.w.  and   'phone  on  separate  week  ends  ex- 
cellent." 

The  following  message  was  received  from 
YLRL  Vice-President  Gilda  Shoblo,  W6KER: 

"I  wish  to  thank  everyone  for  sending  in  reports,  and 
of  course,  my  heartiest  congratulations  to  the  winners, 
as  well  as  my  condolences  to  the  very  fine  losers.  In  the  long 
run  we  all  win.  Some  of  the  reports  have  been  altered, 
mostly  due  to  contestants  sending  in  combined  scores.  I 
hope  the  tabulations  and  awards  are  as  near  correct  as 
possible;  if  not,  I  shall  be  very  happy  to  make  corrections. 
Also,  I  shall  be  pleased  to  receive  suggestions  and  com- 
ments on  the  contest,  so  that  the  next  officer  can  know  of 
any  changes  desired  by  the  contestants. 

Since  the  rules  of  this  contest  were  published,  I  have 
discovered  there  is  a  Silver  Cup  awarded  specifically  for 
top  or  aggregate  score.  Since  this  cup  is  awarded  and  so 
inscribed  for  this  "specific"  category,  and  due  to  the 
many,  many  aggregate  scores  sent  in  for  this  award  (osten- 
sibly), having  no  alternative  but  to  give  this  to  the  winners 
for  which  it  is  intended,  I  have  done  so."

venture  into  a  contest.  Merle  says  that  the  ex- 
periences of  those  two  days  "forced"  her  to  pre- 
serve her  thoughts  on  paper,  as  follows: 

The  Monday  Morning  Blues 

My  ears  ring  with  a  dit-dah  tune  'the  the  contest's 
over  and  I'm  back  to  earth  pushing  a  vacuum 
cleaner  through  a  house  that's  a  shambles.  Dirty 
dishes  in  the  sink  —  quick!  close  the  door  to  the 
shack  —  hide  it  from  human  eyes.  Only  a  ham 
would  understand. 

I  brushed-up  my  c.w.  three  weeks  before  the 
YL-OM  contest  when  a  license  renewal  reared  its 
dit-dah  head.  I  gingerly  touched  the  dit  side  of  the 
bug  and  jumped  clear  across  the  room;  the  result 
of  five  years  of  neglect,  I'm  sure. 

But  thanks  you  patient  OMs;  all  65  of  you.  As 
for  those  who  QRSd,  I'm  certain  you'll  go  to  ham 
heaven  where  there's  no  QRM  or  TVI  and  DX  is  un- 
limited! Forgive  me,  W9D0,  for  making  a  DOG  of 
you  —  conditions  you  know,  not  my  13  w.p.m.

test!  Hope  you  know  better  than  to  count  too  much 
on  this  YL's  untrained  ear. 

One  thing  boomeranged,  though.  Once  after 
a  number  of  repeats  on  a  QTH,  I  was  embarrassed 
and  answered  with  an  R.  Thought  I'd  be  smart 
and  look  him  up  in  the  call  book.  But  the  joke's  on 
me  —  he's  not  in  "Summer  1954."  Moral,  gals:  al- 
ways lead  the  good  clean  life. 

Speaking  of  OMs,  mine  is  a  very  patient  one.  Well, 
fairly  patient.  He'd  wander  into  the  shack  and 
remark  something  Uke  "It's  three  o'clock.  How  about 
something  to  eat?"  I'd  stare  glassy-eyed  while 
busily  calling  CQ  OM.  Quietly,  he'd  leave,  but  I 
know  he  didn't  starve  —  not  with  all  those  dirty 
dishes  I  found  in  the  sink.  On  Sunday  I  knew  for 
sure  that  I  had  married  him  for  better,  not  worse. 
At  0830,  into  the  shack  he  strolled  with  a  breakfast 
tray  —  HAM  and  eggs! 

That's  why  I  feel  so  bad  about  dehberately  letting 
our  Sunday  dinner  burn.  A  roast's  the  thing,  I  had 
thought.  I'd  just  throw  into  into  the  oven;  it  would 
cook  itself.  I  cannot  tell  a  he  (other  than  a  signal 
report).  I  smelled  it  burning  and  pushed  the  thought 
from  my  frenzied  brain.  A  Wisconsin  was  caUing  me

For  the  Experimente 


RESISTOR  HINTS 

IN  reworking  a  Q5-er,  it  was  discovered  that  all 
resistors  were  conductive  between  the  out- 
side surface  and  the  leads.  This  condition  was 
especially  prevalent  in  the  gold-band  section 
of  each  resistor.  Upon  breaking  a  few  of  the 
units  open,  it  appeared  that  they  had  no  in- 
sulating coating  such  as  applied  to  present- 
day  jobs.  Apparently,  the  grey  carbon  impreg- 
nating material  extends  all  the  way  to  the  out- 
side of  each  resistor.  Naturally,  faulty  operation 
of  the  receiver  will  occur  if  one  such  resistor 
makes  contact  with  the  chassis,  another  part  of 
the  circuit,  etc.

POWER-REDUCTION  HINTS  FOR  S.W.R. 
BRIDGE  MEASUREMENTS 

ONE  of  the  problems  frequently  encountered  in 
making  s.w.r.  measurements  is  that  of  reduc- 
ing transmitter  power  output  to  a  level  low 
enough  to  prevent  damage  to  the  bridge.  In 
installations  where  there  is  no  existing  means  of 
controlling  output  from  the  amplifier,  it  is  pos- 
sible to  control  the  power  to  the  bridge  by  means 
of  the  simple  system  shown  in  Fig.  1.  In  this  ar- 
rangement, most  of  the  output  from  the  trans- 
mitter is  dissipated  in  the  52-ohm  dummy  load

Fig.  1  —  A  simple  arrangement  for  reducing  power 
during  s.w.r.  measurements.  A  is  a  "T"  coaxial-cable 
coupler  and  B  is  a  variable  capacitor  with  a  range  of 
approximately  0-100  ^^f- 


and  a  portion  of  the  remaining  power  is  fed  to  the 
bridge  through  a  variable  capacitor. 

The  dummy  load  must  be  capable  of  dissipat- 
ing nearly  the  full  output  from  the  transmitter. 
It  should  be  shielded  and  equipped  for  coaxial- 
cable  input.  The  variable  capacitor  should  also 
be  enclosed  in  a  metal  compartment  and  should 
be  terminated  with  coax  connectors.  A  standard 
"T"  connector  and  short  lengths  of  coax  may 
be  used  for  making  connection  between  the  trans- 
mitter, dummy  load  and  variable  capacitor. 

When  using  this  method  of  power  reduction, 
the  bridge  is  inserted  in  the  transmitter  output 
line  in  the  usual  manner.  Then  adjust  the  variable 
capacitor  for  normal  reflection  of  the  s.w.r.  indi- 
cator and  proceed  as  you  would  with  any  other 
set  of  adjustments  or  measurements.

INPUT  CIRCUIT  FOR  EITHER  CRYSTAL 
OR  CARBON  MICROPHONES 

THE  circuit  shown  in  Fig.  2  permits  feeding  the 
output  of  either  a  crystal  or  a  carbon  micro- 
phone to  the  speech-amplifier  tube.  The  closed- 
circuit  jacks  automatically  convert  the  circuit

for  whichever  type  of  microphone  is  used.  When 
using  a  crystal  or  other  high-impedance  niicro- 
phone,  it  is  plugged  into  J\.  In  this  application, 
the  cathode  circuit  for  the  12AX7  is  completed 
through  J2-  With  Ji  closed  (microphone  plug 
removed)  and  with  a  carbon  microphone  plugged 
into  Ji,  the  stage  operates  as  a  grounded-grid 
amplifier.  The  second  half  of  the  dual  triode  is 
used  as  a  conventional  voltage  amplifier  with  a 
gain  control  in  the  grid  circuit.

CUSTOM-MADE  NAME  PLATES 

ALL  you  need  to  make  attractive  custom-de- 
-^  signed  name  plates  for  the  new  rig  are  a 
package  of  transmitter  decals  (Tekni-Labels, 
Burbank,  Calif.),  narrow  strips  of  aluminum, 
clear  finger  polish  and  a  piece  of  crocus  cloth  or 
polishing  paper. 

The  strips  are  cut  to  the  desired  width  and 
length,  a  mounting  hole  drilled  at  each  end, 
polished  with  the  crocus  cloth  or  paper,  cleaned 
of  abrasive  dust  and  given  a  quick  even  coating 
of  nail  polish.  After  the  polish  dries,  the  decal 
may  be  affixed  and  allowed  to  dry  thoroughly. 
Then  one  or  two  more  coats  of  polish  should  be 
applied,  each  coat  being  given  sufficient  time  to 
dry  completely. 

The  result  is  an  inexpensive  indicator  or  name 
plate  that  is  commercial  looking  in  appearance. 
As  the  drying  of  the  nail  poHsh  is  tricky,  since  it 
dries  so  rapidly,  it  is  best  to  experiment  first 
before  going  into  production.  The  instructions 
supplied  with  the  Tekni-Labels  should  be  fol- 
lowed closely.

QST  for 


CHASSIS-LAYOUT  AID 

THE  construction  practices  chapter  of  recent 
editions  of  The  Radio  Amateur's  Handbook 
makes  the  excellent  suggestion  that  one  com- 
mence construction  by  covering  the  chassis  with 
a  sheet  of  paper.  The  location  of  components, 
mounting  holes,  etc.,  is  then  marked  on  the  paper 
so  that  the  latter  maj'  be  used  as  a  drilling  tem- 
plate for  components  to  be  mounted  above  deck. 
After  drilling,  the  parts  which  require  mounting 
underneath  may  be  located  and  the  mounting 
holes  drilled,  making  sure  by  trial  that  no  inter- 
ference exists  with  parts  mounted  on  top. 

An  easy  way  to  ensure  a  good  alignment  of 
components  below  with  those  above  the  chassis 
is  to  place  a  sheet  of  translucent  paper  (onion- 
skin) on  top  of  the  chassis,  and  mark  on  its  top 
surface  the  position  of  topside  parts.  Then  place 
the  same  sheet  against  the  underside  of  the 
chassis,  unmarked  side  exposed,  and  locate  the 
parts  to  be  mounted  inside  the  chassis.  Since  the 
paper  is  translucent,  these  may  be  easily  placed 
so  as  not  to  interfere  with  components  on  top  of 
the  chassis.

PARALLEL  6Y6s  FOR  THE  SIMPLEST 
MODULATOR 

THE  simple  grid  modulator  described  bv 
W6LNN  in  QST  for  Septeml)er,  1953,  has 
usually  lived  up  to  its  name  if  constructed  with 
a  single  tube  in  the  output  stage.  However,  the 
installation  of  parallel  6Y6s  in  the  modulator  has 
occasionally  resulted  in  instability  within  the 
unit.  With  the  assistance  of  W8RXX,  and  with 
the  addition  of  a  few  inexpensive  components, 
it  has  been  possible  to  stabilize  the  parallel- 
tube  arrangement.  Fig.  3  shows  the  revised 
circuit  which,  incidentally,  is  used  to  modulate 


resistors  R12  through  7?i5  are  the  recent  additions 
to  the  modulator  and  are  the  components  which 
stabihze  the  new  arrangement.  Rg  of  the  one- 
tube  layout  has  been  replaced  with  a  100-ohm 
variable  to  provide  a  convenient  means  of  ad- 
justing the  plate  current  of  the  r.f.  amplifier.  This 
adjustment  is  particularly  helpful  when  re- 
setting the  plate  current  to  half  value  after  band 
changing.

[Editor's  Note:  The  simple  grid  modulator  referred  to 
.ibove  is  also  described  in  Chapter  9  of  recent  editions  of 
the  ARRL  Handbook.'] 

ADDING  A  SPINNING  REEL  TO  THE 
BOW-AND-ARROW  TRICK 

THE  trick  of  using  a  bow  and  arrow  to  shoot  an 
antenna  hah'ard  into  place  can  be  improved 
on  by  using  a  spinning  reel  and  rod  as  a  means  of 
pajnng  out  the  guide  line.  Four-pound  nylon 
test  line  and  a  short  rod  is  the  best  combination 
to  use.  Tie  the  line  to  the  arrow  just  to  the  rear  of 
the  feathers.  As  the  arrow  passes  over  the  top 
of  the  tree  or  other  tj'pe  of  support,  have  the 
person  holding  the  rod  apply  enough  pressure  to 
the  reel  to  control  the  flight  of  the  arrow.  \Mien 
the  arrow  has  landed,  untie  the  nylon  line  and 
fasten  the  halyard  in  place.  Now  haul  the  hal- 
yard back  to  the  firing  position  so  that  the 
halyard  and  antenna  can  be  connected  together.

IMPROVED  R.F.  CABLING  FOR 
REMOTE-TUNED  VFOs 

AFTER  constructing  and  using  several  remote- 
1-  tuned  variable-frequency  oscillators,  it  be- 
came apparent  that  one  of  the  weakest  points  in 
this  system  is  the  cabling  between  the  frequency- 
control  box  and  the  rest  of  the  oscillator.  Instabil-

Many  of  the  components  shown  in  Fig.  3 
bear  designations  —  R^,  Ce,  Li,  etc.  —  which 
refer  to  the  original  diagram  inasmuch  as  these 
parts  remain  unchanged  in  both  value  and 
placement.  With  respect  to  the  original  circuit, 
it  should  be  mentioned  that  the  6SL7  section  of 
the  unit  requires  no  modification.  L2  and  L3  and 


ity  or  intermittent  operation  of  a  VFO  can  fre- 
quently be  traced  to  poor  contacts  in  the  plugs 
and  receptacles  used  to  terminate  the  intercon- 
necting coax  Une.  I  have  found  that  Amphenol 
type  83-22SP  and  83-22R  plugs  and  receptacles, 
respectively,  used  in  conjunction  with.  RG-22/U 
coaxial  cable,  provide  the  most  reliable  tank-to- 
tubc  connections  vet  emplo5'ed.

index,  6M  X  9J^,  cloth  cover.  Price,  $5.00. 

A  question-and-answer  manual  covering  the  eight  ele- 
ments of  the  FCC  commercial  operator  examinations. 
Several  appendices  are  included,  one  correlating  examina- 
tion questions  w'ith  the  normal  progression  of  theory  courses 
in  the  various  subjects,  a  second  giving  specific  references 
to  laws  applicable  to  legal  questions,  a  third  listing  the 
Q  signals,  and  a  fourth  tabulating  general  texts  •nith  a 
notation  of  their  usefulness  in  connection  \vith  specific 
elements  of  the  examinations. 

Introduction  to  UHF  Circuits  and  Components, 

by  Milton  S.  Kiver.  Published  by  D.  Van 
Nostrand  Company,  Inc.  408  pages,  including 
index.  Schematics.  6^  X  9^,  cloth  cover.  Price, 
$7.50. 

Although  the  layman  naturally  thinks  "television" 
when  "u.h.f."  is  mentioned,  the  subject  of  u.h.f.  television 
is  discussed  only  in  one  brief  chapter  in  this  volume.  The 
book  is  actually  a  survey  of  components,  methods  and 
circuits  in  the  v.h.f.-u.h.f.  field  generally,  covering  tubes, 
transmission  lines,  waveguides  and  antennas  used  in  this 
part  of  the  frequency  spectrum.  Chapters  on  measurements 
and  receivers  also  are  included.  Gives  a  good  over-all  picture 
of  the  field. 

Elements  of  Radio  Servicing,  by  William 
Marcus  and  Alex  Levy,  second  edition.  Pub- 
lished by  McGraw  Hill  Book  Co.,  Inc.,  New 
York  City.  666  pages,  including  index.  Sche- 
matics. 6J^  X  9J^,  cloth  cover.  Price,  $6.00. 

In  addition  to  the  inclusion  of  new  material  on  features 
of  a.m.  broadcast  receivers  that  have  been  introduced 
since  the  appearance  of  the  first  edition,  new  chapters  have 
been  added  to  cover  f.m.  receivers  as  well.  The  text  is 
general,  dealing  with  types  of  circuits  and  methods  rather 
than  specific  receivers.  Test  instruments  and  their  proper 
use  are  discussed. 

Elements  of  Radio,  Third  Edition,  by  A. 
Marcus  and  Wm.  Marcus.  Published  by  Prentice- 
Hall,  Inc.,  70  Fifth  Ave.,  New  York  11,  N.  Y. 
6  X  8H  inches,  cloth  cover,  771  pages,  including 
index.  Price,  $6.00. 

Very  suitable  for  the  raw  beginner,  as  well  as  useful  to 
those  who  have  some  practical  acquaintance  with  radio 
circuits  and  want  to  get  an  elementary  technical  back- 
ground. The  book  is  divided  into  two  parts,  the  first  of  which 
teaches  by  using  the  development  of  the  broadcast  receiver 
as  a  theme,  carrying  through  from  the  simplest  crystal  set 
to  modern  types.  This  section  is  entirely  nonmathematical. 
The  second  part  is  an  elementary  theory  course  developed 
along  more  conventional  lines.  There  are  questions  and 
problems  with  each  of  the  forty-two  chapters. 

How  To  Install  TV  Antennas,  by  Samuel  L. 
Marshall.  Published  by  John  F.  Rider  Publisher, 
Inc.,  480  Canal  St.,  New  York  13,  N.  Y.  124 
pages,  5V^  X  8V^,  paper  cover.  Price,  $2.50. 

About  half  of  the  book  is  devoted  to  a  discussion  of  TV 
antenna  characteristics,  transmission  lines,  and  pointers  in 
selecting  the  proper  antenna  for  a  given  situation;  the 
remainder  deals  with  the  actual  mechanics  of  installation. 
Available  materials  and  fittings  are  described,  and  con- 
siderable attention  is  paid  to  such  factors  as  the  stresses 
on  masts  and  guy  wires.  Much  of  the  antenna  installation 
data  appears  to  be  useful  for  amateur  antennas  as  well. 


Preview  —  DX  Contest  High 
C.W.  Scores 

Excitement  reigned  supreme  during  the  21st 
ARRL  International  DX  Competition  c.w.  por- 
tions. February  band  conditions  allegedly  were 
the  best  in  years.  Then  came  March  and  Ken- 
neUy-Heaviside  lowered  the  boom  in  a  sudden 
about-face  that  diehard  DXers  have  recently 
learned  to  expect.  With  claimed  scores,  multi- 
pliers and  contacts  shown  in  that  order,  here  are 
the  leaders  in  U.  S.  and  Canada:

QST  for 


CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD 


Whom? 

It's  time  we  dipped  into  our  DXtensive  back- 
log of  potential  "How's"  badinage  and  drew 
forth  a  sequel  to  our  Pearl  Harbor  comments  in 
last  December's  QST.  You'll  recall  we  inquired 
as  to  the  identity  of  the  DXer  —  DXer  X,  if  you 
please  —  who  was  communicating  with  K6SRZ 
on  20-meter  'phone  at  0700  Hawaiian  time  on  the 
morning  of  December  7,  1941.  This  intriguing 
research  project  was  initiated  by  W2TNC, 
K6SRZ  operator  at  the  time. 

Well,  the  plot  thickens,  if  anything  Though 
we  didn't  scare  up  the  western  W  who  held  down 
the  Stateside  end  of  that  historic  QSO  we  did 
raise  a  casual  eavesdropper  who  also  heard  the 
stick  of  bombs  that  overloaded  K6SRZ's  modu- 
lator one  fateful  Sunday  morn  over  thirteen 
years  ago.  It  was  W7GAT,  then  news  chief  of  the 
weekly  Oregon  Statesmen  (Salem,  Ore.)  and  now 
publisher  of  the  Mount  Vernon,  Washington, 
Argus.  Steve  swells  to  a  grand  total  of  two  the 
number  of  persons  who  heard  one  of  the  most 
momentous  transmissions  in  ham  history.  We 
excerpt  from  a  yellowing  page  of  the  special 
Statesman  extra  dated  that  December  7th: 

Hawaiian  Ham  Telia  Salem 
Radioman  of  Things  Amiss 

"This  looks  bad!   I   can't  stay  in   this  place!" 

An  excited,  doubtless  frightened,  voice  spoke 
those  words  over  the  20-meter  radio  band  Sunday 
forenoon,  tipping  oft  [W7GAT1  that  something  was 
amiss  in  the  Hawaiian  Islands. 

"Can't  talk  anymore,"  the  voice  said.  "Signing 
off  —  you  take  over." 

Then  the  Hawaiian  operator  shut  off  his  station 
and  a  Salt  Lake  City  amateur  responded:  "Okay, 
but  you  didn't  say  what  was  the  matter.  73  .  .  ." 

No  time  to  polish  the  doorknob  on  that  QRT! 
This  clipping  considerably  narrows  the  search 
for  Station  X  —  beyond  much  doubt  he  was  a 
W6  in  the  Salt  Lake  City  area.  But  where  is  he 
now?  What  part,  if  any,  did  he  later  play  in  the 
hostilities  he  so  dramatically  heard  begin?  These 
questions  and  others  may  never  be  answered,  for 
Station  X  seems  to  have  vanished  into  the  past 
along  with  the  lost  logs  of  old  K6SRZ. 


Bouncing  back  after  May  mayhem  at  the 
hands  of  DXHPDS  antagonists,  W6MUR  dis- 
turbs us  with  excerpts  from  his  latest  treatise  on 
avocational  communicational  diseases.  The  fol- 
lowing ailments  are  identifiable  with  DX  hunting 
in  particular: 

Operational  Turpitude  —  A  contagion  resulting  from  ex- 
cessive exposure  to  DX  contests. 

*  Pleaae  mail  all  reports  of  DX  activity  to  DX  Editor 
Newkirk  at  4128  North  Tripp  Ave.,  Chicago  41,  Illinois. 


Pigmentary  Impotence  —  Frustrating  inability  to  raise 
the  "easy"  ones  in  DX  contests. 

Immedicable  Perpetuuphobia  — -  Screaming  mimics  as  a 
result  of  agitation  through  immersion  in  pile-ups. 

Mental  Plausabilianism  —  Reflexive  log  entries  made 
when  rare  ones  come  back  to  people  with  calls  like  yours. 

Radiational  Astigmatism  —  A  strange  malady  that  causes 
its  \'ictims  to  answer  directional  CQs  of  any  and  all  types. 

Flatulent  Amphigoria  —  Cultivation  of  a  permanent 
sneer  brought  on  by  DX  column  flashes  about  DXpeditions 
to  HV,  ZA  and  Northeast  Dontundustan. 

These  afflictions  have  several  symptoms  in 
common  —  glazed  eyes,  twitching  elbows,  desul- 
tory mumbling  —  and  accurate  diagnoses  are 
difficult.  Beyond  all  dubiety  the  DX  Bug  is 
secondary  host  to  the  infectious  parasites  in- 
volved. Beware!

Sunspot  numbers  again  soar  upward,  north  Atlantic  propagation  pallis  become  more  solid  day  by  day,  and  it 
won't  be  very  long  before  S9-plus  Europe-LI.S.A.  QSOs  are  the  14-Mc.  rule  rather  than  the  exception.  OZ2KR, 
HER  and  CTICO,  pictured  here  from  left  to  right,  are  among  the  Continental  DX  crew  who  look  forward  to  "the 
good  old  DX  days"  revisited.  All  three  are  OTs;  HER,  especially,  for  Mario  recently  completed  his  30th  year  as  an

From  ubiquitous  Bob  Roberts,  G2RO:  "I  have  just  com- 
pleted my  last  and  longest  tour  of  this  series  and  cards  have

get  one  in  due  course.  Calls  covered  are  VRIRO,  VR2RO, 
VL0RO  (Nauru).  VR4RO,  VQ8AY  and  ZC4R0.  It  may  be 
worth  mentioning  that  VQ8.\Y  is  my  own  issued  call  and 
not  a  borrowed  one  as  some  have  thought,  .\uthorities  cotild 

not  give  me  VQ8R0."  . VU2JP  gives  assurance  that 

QSLs  bound  for  VU  AC3  and  kCA  areas  will  be  relayed  via 
Box  1,  Munnar,  Travancore,  India,  as  usual  even  when  he's 
traveling  or  on  U.K.  furlough  in  Scottish  highlands  ._._._ 
Regarding  the  VPIGG  address  run  last  month,  QSLs  will  be 
held  by  VR2AS  pending  ex-VPlGG's  arrival  in  Fiji  after 
completing  leave  in  the  British  Isles  ._._._  We  learn  from 
W6LTY  that  VK9DB  assumes  managership  of  Papua

after  a  recent  QSO  with  VS2DQ WIYOU  correctly

in  an  envelope  now  can  be  sent  anywhere  in  the  world  via 
air  mail  for  ten  (10)  cents  —  provided  it  is  no  smaller  than

Oceania  —  From  KC6AA  of  Yap,  Western  Carolines: 
"Would  like  to  remind  the  DX  gang  that  KC6  stations  do 
not  work  the  same  frequencies  on  40  that  Stateside  DXers 
work.  Our  40-meter  band  is  7000-7150  kc,  7100-7150  kc. 
for  'phone.  I  work  40  almost  exclusively  and  always  tune  the 
Stateside  'phone  band  when  working  'phone.  KC6AA  can  be 
found  almost  nightly  on  7116  kc."  The  areas  compassed  by 
the  Eastern  vs.  Western  CaroUnes  are  somewhat  tricky  to 
determine.  The  Eastern  Carolines  appear  eis  just  "Caro- 
lines" on  most  maps  and  this  may  account  for  the  difficulty. 
Kno\ving  that  Truk,  Ponape  and  Kusaie  are  in  the  Eastern 
Carolines,  and  that  the  Palaus,  Ulithi  and  Yap  are  in  the 
Western   group   should    help   keep    the   bearings   straight

W5LCI's  Pitcairn  confirmation  finally  came  about  through

bogus  VR6AC  on  14  Mc.  This  time  it  paid  to  work  a  phony! 

Europe  —  The  experience  of  HBIMX  points  up  why 
DX  stations  rarely  QSL  first  these  days.  Kurt's  Liechten- 
stein operation  resulted  in  nearly  2000  QSOs  with  91  coun- 
tries, 852  contacts  with  the  U.  S.  A.  Only  one  out  of  every 
ten  U.  S.  stations  bothered  to  answer  his  cards  and  just  three 
out  of  every  ten  non-U.  S.  stations  replied,  according  to 

F7ER "Present  3A2  activity  is  entirely  confined 

to  local  'phone  work.  The  only  DX  activity  from  Monaco 
occurs  when  some  DXpedition-type  station  gets  on  the  air 
there.  Such  activity  is  usually  announced  in  advance 
through  proper  channels.  Ergo,  any  3A2  aoti\-ity  (particu- 
larly on  c.w.)  that  pops  up  unannounced  should  be  viewed 
with  dark  suspicion,  to  say  the  least."  These  words  from 
OT  DXpediter  W6SAI-FP8AC-3A2AF-7B4QF  who  noted 
that  his  3A2AF  call  recently  was  borrowed  for  14-Mc.  use 
by  some  unscrupulous  individual.  Bill  adds,  "Come  the 
peak  of  the  sunspot  cycle,  I  hope  to  polish  off  some  spots 
like  3A2  PX  and  HV  to  everyone's  satisfaction.  As  you 
know,  the  main  requirement  for  a  DXpeditionary  man  is  a 
strong  back  and  a  weak  mind."  ._._._  Two-letter  Irish

New  Apparatus 

The  Model  587  Audio  Bandpass 
Filter 

NUMEROUS  ARTICLES  in  QST  and  other  publica- 
tions have  pointed  out  during  past  years  the 
advantages  of  restricting  the  speech  range  of  a 
'phone  transmitter.  On  a.m.,  reducing  some  of  the 
low-frequency  response  can  save  modulator  power 
and  actually  add  to  inteUigibihty.  In  s.s.b.  rigs, 
restricting  the  audio  range  "protects"  the  audio 
phase-shift  network  and  results  in  better  side- 
band suppression,  and  it  eases  the  burden  on  an 
e.xciter  using  a  filter.  A  number  of  designs  in  the 
past  have  shown  a  filter  or  other  device  for  re- 
stricting the  audio  range  of  a  speech  ampUfier  for 
the  reasons  outlined  above. 

The  operator  who  has  alwaj^s  wanted  to  try 
an  audio  filter  but  is  reluctant  to  dig  into  the  rig 
to  install  it  will  be  interested  in  the  Model  587 
Audio  Bandpass  Filter.  This  small  unit  is  de- 
signed to  go  in  the  microphone  cable  between 
microphone  and  transmitter,  so  no  work  is  in- 
volved outside  of  making  the  connections.  The 
input  side  of  the  filter  has  an  Amphenol  micro- 
phone jack  that  takes  the  usual  connector,  and 
the  output  side  is  a  53'-2-inch  length  of  micro- 
phone cable  terminated  in  a  microphone  plug. 
The  only  time  you  might  have  to  modify  any- 
thing is  when  j^our  transmitter  is  fitted  with 
something  other  than  the  Amphenol  microphone 
jack,  but  even  then  it  is  easy  to  rig  up  an  adaptor. 

The  filter  itself  is  housed  in  a  1  J^-inch  diameter 
metal  tube  4  inches  long,  so  it  doesn't  take  up 
much  room  on  the  operating  desk.  It  is  designed 
to  work  only  with  crystal  microphones,  and  be- 
cause such  microphones  represent  practically  a 
pure  reactance,  the  filter  has  practically  no  in- 
sertion loss.  This  means  that  if  the  gain  of  your 
speech  amplifier  is  marginal  you  can  stiU  use  the 
filter  without  cutting  down  your  modulation. 
Although  different  microphones  vary  slightly  in 
their  output  capacitance,  the  manufacturer's 
tests  show  that  the  extremes  of  this  range  result 
in  only  about  100  cj^les  difference  in  the  low- 
frequency  cut-off  point.  The  manufacturer's  re- 
sponse curve  of  the  filter  indicates  the  response 
to  be  down  .3  db.  at  450  and  3300  cycles,  and  20 
db.  down  at  210  and  7300  cycles. 

But  a  coldly  scientific  response  curve  doesn't 
give  the  whole  story,  and  we  thought  that  manj^ 
readers  would  be  interested  in  what  the  filter 
does  to  speech.  The  best  test  we  could  think  of 
along  these  lines  was  to  use  the  filter  in  the 
microphone  lead  feeding  a  "medium  hi-fi"  unit, 
svntching  the  filter  in  and  out  as  a  number  of 
office  guinea  pigs  took  turns  speaking  into  the 
microphone.  This  was  considered  to  be  a  better 
test  than  modulating  a  transmitter  and  listening 
on  a  receiver,  since  it  eliminated  the  bandpas.«: 
effects  of  the  receiver  and  the  possible  distortion 
in  both  transmitter  and  receiver.  The  results 
were  rather  interesting,  we  thought.  In  most 
cases,  observers  reported  no  significant  change  in 
the  voice  characteristirs.  However,  on  two  voices 


(one  male,  one  female)  it  did  change  the  voice 
characteristic  noticeablj^  —  observers  agreed  that 
these  were  "high-pitched"  voices.  The  consensus 
was  that  the  filter  has  good  "balance"  for  most 
voices,  but  there  will  be  a  few  where  the  use  of 
the  filter  will  change  the  voice  characteristic. 
Since  this  is  bound  to  occur  with  any  fixed  filter 
design,  it  would  appear  that  the  manufacturer 
has  made  a  very  good  choice. 

The  Model  587  Audio  Bandpass  Filter  is  manu- 
factured by  the  R.  L.  Drake  Company.

CONDUCTED  BY  EDWARD  P.  TILTON,  WIHDQ 


We've  tried  v.h.f.  here,  but  it  just  doesu't 
work!" 
Over  the  past  twenty  years  or  so  we've 
heard  this  lament  from  just  about  every  section 
of  the  country,  including  areas  that  eventually 
proved  to  be  prize  v.h.f.  locations.  How  is  it  that 
80  many  hams,  some  of  them  in  spots  that  could 
hardly  have  been  more  favorable,  have  come  to 
the  conclusion  that  they  could  not  do  interesting 
work  on  the  frequencies  above  50  Mc? 

Some  have  made  their  initial  efforts  with  inef- 
fective gear,  certainly.  You  wouldn't  expect  to 
set  any  of  our  lower  frequencies  on  fire  with  10 
watts,  a  broadband  receiver  and  a  small  antenna. 
Why  "try  v.h.f."  with  such  a  set-up?  Sure,  low 
power  and  simple  gear  work  well  enough  if  you 
have  plenty  of  near-by  activity,  but  if  you're  go- 
ing for  extended  ranges  j'ou'U  need  the  best  gear 
obtainable.  A  good  big  antenna,  a  low-noise 
receiver  and  good  stability  and  selectivity  are 
musts.  High  power  paj'S  off  handsomely,  too. 

But  alert  operating  is  even  more  important. 
Most  of  the  trouble,  we  think,  has  been  lack  of 
knowledge  of  what  to  expect,  and  when  to  expect 
it,  and  too  few  stations  within  the  possible  work- 
ing range.  Coordination  of  operating  schedules 
can  be  mighty  important.  The  best  location  in 
the  world  will  produce  a  complete  blank,  if  there 
is  nobody  on  the  air  in  the  territory  you're  scan- 
ning with  j-our  beam.  Countless  opportunities  for 
v.h.f.  DX  are  missed  in  this  way. 

Take  the  Gulf  States,  for  example.  There  is 
plenty  of  evidence  that  from  Florida  around  to 
Texas,  and  up  the  Atlantic  Seaboard  to  the 
north,  too,  tropospheric  propagation  on  the  fre- 
quencies above  50  Mc.  is  good  more  often  than 
almost  anywhere  else  in  the  United  States,  yet 
tropospheric  DX  on  the  amateur  v.h.f.  bands  is 
still  a  rarity  over  these  routes. 

Early  in  May  j-our  conductor  visited  radio 
clubs  in  several  Florida  cities,  and  met  with 
similar  groups  in  Georgia  and  North  and  South 
Carolina.  All  along  the  line  we  found  evidence  of 
increasing  v.h.f.  interest.  Getting  going  on  144 
Mc,  particularly,  was  a  major  objective.  Befoi'e 
we  arrived  back  in  West  Hartford  2-meter  DX 
had  already  been  heard  or  worked  over  several 


Uoii  Goishay,  president  of  the  2  Meter  and  Down 
Club  of  Los  Angeles,  shows  some  of  the  1215-Mc.  gear 
exhibited  at  a  recent  meeting  of  the  club  during  which 
this  band  was  featured.  Numbered  items  are  described 
in  the  text. 


southern  paths  that  had  never  been  spanned 
before,  and  new  southern  states  should  be  show- 
ing in  the  "worked"  totals  of  Wis,  2s,  and  3s,  as 
they  already  have  appeared  in  the  records  of 
Texas,  Louisiana  and  Mississippi  W5s. 

Here  are  some  reports  that  indicate  the  possi- 
bilities. W4UUF,  Pensacola,  Fla.,  who  got  on  144 
Mc.  through  the  efforts  of  W5RCI  last  summer, 
has  been  working  Texas  stations  frequently  since 
the  middle  of  March.  W5FEK,  Houston,  says 
that  W4UUF  has  hit  S9-plus  levels  on  several 
occasions,  and  has  been  heard  working  stations 
at  500  to  600  miles  as  fast  as  he  could  turn  from 
one  to  another.  We'll  bet  that  Tampa  to  Houston, 
800  miles,  could  have  been  worked  almost  as 
readily. 

From  Orlando,  W4CSS  writes  that  he  and 
W4MSX  and  W4QN  have  heard  W4UUF.  This 
is  an  all-Florida  circuit  of  some  400  miles  that 
almost  certainly  could  have  included  Jackson- 
ville, Miami  and  other  Florida  cities,  too.  Just 
after  midnight,  May  8th,  W4QN  heard  W4SMA, 
Whiteville,  N.  C,  for  more  than  an  hour,  but 
could  not  raise  him.  This  is  a  450-mile  over- 
water  path  that  is  probably  close  to  ideal  for 
v.h.f.  work.  We  suspect  that  Norfolk,  Baltimore, 
or  even  Philadelphia  might  be  worked  from 
Florida  points  now  and  then,  too.  To  aid  in 
establishing  contact  with  distant  points,  Orlando 
stations   aim    their   anteimas   on   the   following

schedule,  transmitting  and  listening  for  DX:  2045 
EST  —  Miami  area;  2100  —  local  check,  beamed 
on  Gainesville  or  Tampa;  2115  —  Pensacola; 
2130  —  Tampa;  2145  —  various  directions,  de- 
pending on  conditions  observed  during  above 
checks. 

Activity  on  144  Mc.  in  North  Carolina  has 
been  coming  along  well  in  recent  months.  Our 
meeting  in  Raleigh  was  attended  by  an  enthusias- 
tic band  of  2-meter  men  who  are  working  the 
band  for  all  it's  worth,  several  of  them  in  loca- 
tions that  should  be  hot  spots  for  2-meter  DX. 
W4MDA,  Wilmington,  N.  C,  has  since  written 
that  on  the  night  of  May  10th,  while  W4MDA 
was  at  work,  K4CTW  picked  up  a  weak  signal

with  his  beam  north.  Peaking  the  beam  position 
indicated  that  the  signal  was  from  the  south,  and 
further  listening  showed  it  to  be  W4GG0  in 
Miami!  He  was  in  contact  with  several  locals,  and 
the  following  were  identified:  W4UIW,  Hialeah; 
W4UTJ,  location  unknown;  and  W4JZB,  Holly- 
wood. The  path  from  Wilmington  to  Florida 
East  Coast  cities  is  entirely  over  water.  Though 
it's  some  600  miles  to  Miami,  we  think  the  hop 
might  be  made  quite  often  on  144  Mc. 

W4CVQ,  Raleigh,  and  W^4MDA  and  W4SMA 
demonstrated  their  ability  to  work  north  on  the 
night  of  May  3rd,  and  into  the  following  morning, 
contacting  innumerable  Wis,  2s  and  3s  on  144 
Mc.  The  best  DX  we've  heard  of  as  the  result 
of  this  night's  work  is  W4MDA  to  WlJSM, 
Waltham,  Mass.,  close  to  700  miles.  As  signals 
were  good  over  this  path  it  is  obvious  that  longer 
distances  await  only  the  appearance  of  stations 
on  144  Mc.  in  South  Carolina  and  Georgia. 

From  now  on  through  the  summer  and  fall 
months  there  will  be  many  opportunities  for 
work  over  distances  of  1000  miles  or  more  on  144 
Mc.  and  possibly  higher  bands.  The  50-Mc.  band 
will  be  open  for  hops  up  to  at  least  2500  miles 
during  the  early  summer.  The  Atlantic  Seaboard 
and  the  Gulf  Coast  are  only  two  of  the  many 
paths  where  such  work  will  be  possible.  The 
Pacific  Coast,  from  San  Diego  to  Seattle,  should 
be  included  in  the  potential  DX  paths  for  144 
Mc.  We  know  that  the  vast  Middle  West  can  be 
crossed  in  any  direction  by  2-meter  signals,  and 
even  the  highest  mountains  and  roughest  terrain 
can  be  covered  under  certain  conditions.  Whether 
or  not  we  work  DX  on  the  v.h.f.  bands  this  sum- 
mer depends  far  less  on  the  character  of  our  loca- 
tions than  on  whether  there  is  activity  in  the 
right  places,  at  the  right  times,  with  the  right 
kind  of  equipment.  If  we  take  maximum  ad- 
vantage of  the  breaks  that  Nature  will  provide, 
there  should  be  many  new  states  worked  on  50 
and  144  Mc.  and  new  DX  records  on  220  and  420 
Mc.  to  report  before  the  end  of  1955. 

Here  and  There  on  the  V.H.F.  Bands 

The  best  432-Mc.  DX  so  far  reported  in  1955  was  worked 
April  30th  by  W3BSV,  Salisbury,  Md.,  and  WlOOP, 
Needham,  Mass.  This  365-mile  contact,  at  2205  EST,  was 
made  with  good  signals  both  ways,  indicating  that  if  the 
432-Mc.  enthusiasts  around  Norfolk,  Va.,  had  been  on 
hand  a  new  record  might  have  been  set. 

The  night  of  May  3rd  was  a  big  one  for  VEIQZ,  Dart- 
mouth, N.  S.  Beginning  about  2120  EST,  Oscar  heard 
144-Mc.  DX  signals,  and  between  then  and  0032  EST  he 
worked  WIDEO,  Cape  EUzabeth,  Maine,  WlKHL,  S. 
Norwalk,  Conn.,  WIKYF,  Ridgefield,  Conn.,  W2TBD, 
Medford,  N.  J.,  K2IEJ,  Oceanside.  L.  I.,  and  WIREZ, 
Stratford,  Conn.  W2TBD  is  about  650  miles.  VEIQY, 
Yarmouth,  N.  S.,  also  had  a  busy  time  that  night,  but  we 
have  no  record  of  his  contacts. 

The  2-meter  DX  schedules  of  W7VMP  (May  QST,  page 
59)  have  yielded  no  positive  results  up  to  press  time,  but  a 
separate  sked  with  W6WSQ  is  producing  regularly.  It  is 
350  miles  and  many  mountains  from  Phoenix  to  Pasadena, 
but  signals  are  being  heard  regularly,  though  weakly,  each 
way. 

We  get  some  of  our  v.h.f.  news  the  long  way.  This  tidbit 
came  from  TI2BX.  He  says  that  C02XZ  will  be  trying  for 
U.  S.  contacts  on  146  Mc.  after  about  the  middle  of  June. 
Transmissions  of  3  minutes'  duration  will  be  made  at  1230 
and  1300,  1800  and  1900,  and  2030  and  2100  EST,  with 
listening  periods  following  each  transmission.

QST  for 


The  advent  of  Technicians  on  50  Mc.  has  helped  the 
activity  picture  markedly.  Not  only  has  the  new  order 
produced  additional  stations,  but  it  has  encouraged  the  old 
hands  to  spend  more  time  on  the  band.  Here  are  a  few 
regularly  scheduled  operations  we've  heard  of  recently.  In 
the  Puget  Sound  area  W7s  TMU  YJE  DYD  TMM  PQS 
UFE  PRW  KGQ  VIC  PZP  KO  and  GOU  are  on  50.4 
regularly,  checking  the  band  at  1900  PST  nightly.  WoZVF 
is  on  51.16  Mc,  evenings  and  early  mornings.  W0FKY 
and  W0CNM  are  active  regularly  in  Grand  Junction, 
Colo.,  also  making  trips  into  Utah  in  the  hope  of  providing 
that  very  rare  state  for  some  of  the  gang.  W0rKY  is  on 
50.064.  Hal  reports  that  there  is  an  active  2-meter  net 
in  Western  Colorado,  comprising  W0CNM,  144.1  Mc, 
W0PXZ,  147.2,  W0QEL,  144.4,  W0PCB,  144.5,  and 
W0FKY,  144.018. 

From  the  R.F.  Carrier,  Dayton  Amateur  Radio  Asso- 
ciation sheet,  we  learn  that  2100  is  6-meter  time  in  the 
Dayton  area.  W8WRN,  Columbus,  checks  6  (makes  trans- 
missions; no  cold-filament  listening)  several  times  daily. 
W8CMS,  Newton  Falls,  Ohio,  says  that  about  20  new  sta- 
tions have  appeared  locally,  with  prospects  good  for  at 
least  10  more  soon.  Claire  now  has  a  4-125A  in  the  final  on  6. 
W8PCK,  Silverton,  Ohio,  is  on  each  morning,  Monday 
through  Friday,  between  0900  and  1115,  and  at  all  hours 
over  week  ends.  He  says  that  W8s  KQK  SVU  QIS  PLB 
JSW  LPD  PCK  and  SDJ  are  keeping  the  band  active  in  the 
Cincinnati  area.  An  unsigned  note  reports  that  the  Joliet, 
111.,  Amateur  Radio  Society  has  a  net  on  53.28  Mc.  W90KM 
and  W9VQ0  monitor  this  frequency  regularly  with  fix- 
tuned  receivers. 

That  Nevada-Utah  expedition  we  reported  in  May  QST 
is  being  whipped  into  final  form  by  W2QCY.  The  6146 
transmitter  delivers  45  watts  output,  and  the  converter 
is  all  set,  as  is  the  audio  section.  Some  test  hops  to  near-by 
liigh  locations  will  be  made  in  June,  to  be  sure  that  all  is  in 
order  for  the  big  one  the  latter  part  of  the  month.  Provision 
will  be  made  for  VFO  operation,  both  'phone  and  c.w. 
Operation  will  be  undertaken  from  Utah  and  Nevada  loca- 
tions during  the  latter  part  of  June  and  early  July. 

That  hard-to-work  state  of  Nebraska  will  be  on  tap 
again  this  summer,  courtesy  of  W9EET/0,  at  Lincoln. 
Gordon  will  be  set  up  about  July  5th,  and  will  operate 
through  at  least  the  16th.  Hia  rig  wiU  run  90  watts  input  on 
50.1  to  50.4  Mc.  He  will  QSL  all  contacts,  but  eager  ones 
may  write  him  at  liis  Callbook  address  in  Chicago. 

"The  50-Mc.  DX  season  got  under  way  in  good  style  over 
most  of  the  country  during  May,  and  DX  reports  were 
coming  in  to  your  conductor's  desk  in  numbers  we've  not 
seen  in  some  years.  Sporadic-£^  skip  of  the  single-hop  vari- 
ety is  a  common  occurrence  in  May,  June  and  July,  despite 
the  fact  that  it  always  comes  as  a  big  surprise  to  the  new- 
comer to  learn  that  contacts  can  be  made  on  50  Mc.  over 
distances  of  1200  miles  or  more.  Individual  reporting  of 
two-way  work  is  out  of  the  question  at  this  season,  because 
of  the  great  number  of  contacts  made.  We're  always  glad 
to  have  the  reports,  however,  as  they  help  to  keep  the 
national  picture  in  focus,  so  keep  'em  coming. 

If  you  have  trouble  reading  the  modulation  on  weak 
signals,  try  turning  on  the  b.f.o.  and  tuning  it  to  zero  beat, 
says  W9GAB,  Beloit,  Wise.  On  some  receivers  this  will 
make  an  appreciable  improvement  in  the  readability  of 
voice  modulation. 

The  2-meter  net  of  the  Atlanta  area,  inactive  for  some 
time,  is  being  reactivated.  W4LRR  reports  that  a  meeting 
is  held  each  Sunday  at  1300,  on  144.138  Mc.  The  gang 
usually  get  together  Saturdays  around  1000. 

W5FEK,  Houston,  reports  some  nice  work  on  144  Mc. 
W5UUM  at  Edna,  W5IHS,  Eagle  Lake,  and  W5IRP, 
Livingston,  work  regularly  at  noon.  Livingston  is  about 
120  miles,  and  Edna  is  160  miles.  W5IRP  has  also  worked 
W5E1V,  Alice,  Texas,  about  290  miles  on  noontime  skeds. 
These  are  not  long  distances  for  band-open  conditions,  but 
the  skeds  are  maintained  at  a  time  of  day  when  propagation 
is  not  likely  to  be  too  favorable. 

V.h.f.  DX  tip  from  a  guy  who  never  works  any,  W9BRD. 
Rod  sits  for  hours  at  the  console  of  KSB242  listening  to  the 
signals  rolling  in  on  the  155-Mc.  police  band.  He  says  that 
there  are  hundreds  of  stations  on  155.37  Mc,  and  155.01, 
1.55.13,  155.25,  155.61  and  155.73  are  other  widely-used 
channels.  Other  frequencies  in  the  same  part  of  the  spectrum 
are  used  locally.  As  the  point-to-point  stations  give  their 
locations  in  each  transmission,  the  signals  are  reUable  in- 
dicators of  good  v.h.f.  conditions.  Now  you  may  not  be  set 
up  for  listening  in  this  frequency  range,  but  plenty  of  ham

Confusion  in  the  Picnic  Department.  Unknown  to  each 
other,  the  Terre  Haute  and  Western  Michigan  v.h.f.  groups 
scheduled  picnics  on  the  same  date,  July  31st.  When  the 
Michigan  gang  heard  that  they  decided  to  move  their  date 
to  August  14th,  Turkey  Run  having  become  something  of 
a  National  Convention  of  v.h.f.  operators  in  recent  years.

Here's  a  220-Mc  item  we  missed  last  month.  On  April 
22nd  W5AJG  hit  the  jackpot.  After  catching  a  new  state 
on  144  Mc.  by  working  W4UUM,  Pensacola,  Fla.,  he 
hooked  up  with  W5JTI,  Jackson,  Miss.  Signals  were  strong 
on  144,  so  they  changed  to  220  and  worked  on  the  higher 
band  with  equal  signal  strength.  This  is  just  under  400 
miles,  and  WSAJG's  first  out-of-Texas  contact  on  220. 

1215  Night  in  Los  Angeles 

The  Two  Meter  and  Down  Club  of  Los  Angeles  has  been 
an  eminently  successful  v.h.f.  club  for  some  years  now,  but 
the  "and  Down"  part  of  the  organization's  name  has  not 
received  too  much  attention.  There  has  been  scattered 
activity  on  220  and  420  Mc,  but  little  on  the  higher  bands. 
To  encourage  members  to  move  to  higher  frequencies,  the 
club  recently  staged  a  1215-Mc.  night,  under  the  direction 
of  its  president,  Don  Goshay,  W6MMU. 

Members  were  urged  to  bring  equipment  for  1215  Mc. 
and  higher  bands  to  the  meeting  for  others  to  see.  Some  of 
the  gear  is  shown  by  W6MMU  in  the  accompanying 
photograph  by  K6GLG.  Item  1  is  Don's  parabolic  reflector. 
The  illuminator  has  a  standing-wave  ratio  of  1.09:1  at  1225 
Mc.  Just  below  it  is  a  collinear  array  with  plane  reflector 
made  by  W6NLZ.  Phasing  lines  are  electrically  one  wave- 
length long,  so  no  transposition  is  needed.  Pairs  are  spaced 
%  wavelength  apart  physically.  Item  3  is  a  mixer  assembly 
by  W6DQJ.  It  has  a  quarter-wave  coaxial  line  tuned  at  the

More  FCC  Suspensions.  Several  different 
and  significant  FCC  actions  have  already  been  re- 
ported to  you;  see  page  70  of  March  '55  QST. 
To  those  now  add  the  following: 

FCC  Ordered  (29  April,  1955)  that  the  Novice  Class 
operator  license  of  A.  R.  Bookoff,  Miami,  Florida,  be 
suspended  120  days,  that  the  license  be  turned  in  to  the 
FCC  and  KN4BQU  not  be  permitted  to  be  operated  by  any 
person  in  the  120-day  period,  it  appearing  that  the  licensee,  on 
Jan.  14,  1955,  violated  Sec.  12.2.3(e)  and  12.158  of  FCC 
rules  by  using  call  sign  K4BQU  which  is  not  assigned  to 
him  and  by  transmitting  on  a  frequency  of  3855  kc.  using 
Type  A-3  emission  which  is  not  authorized  for  use  by 
Novice  Class  licensees. 

FCC  Ordered  (11  May,  1955)  that  the  Technician  Class 
amateur  operator  license  of  Charles  K.  Heath,  Hinsdale, 
Illinois,  be  suspended  for  six  months,  that  the  license  be 
turned  in  to  the  FCC  and  W9ZIZ  not  be  permitted  to  be 
operated  by  any  person  in  the  period  of  the  suspension,  it 
appearing  that  the  licensee  while  operating  or  supervising 
work  at  his  amateur  station  violated  Sections  12.23  and 
12.28  of  FCC  rules  by  transmitting  and/or  authorizing 
others  to  use  his  equipment  on  frequencies  below  50  Mc. 
He  violated  sections  12.82(a)  and  12.158  of  the  rules  with 
regularity  by  using  and/or  offering  others  while  using  his 
equipment  to  use  call  signs  not  assigned  to  him,  especially 
W9WFN/9;  and  also  violated  section  12.136(b)  by  not 
keeping  his  station  log  with  proper  signatures. 

About  Learning  the  Code.  Having  memorized 

the  code  by  its  sound  values  many  (starting  in) 
look  to  some  radio  club  or  operator  who  is  a 
friend  for  'round-the-table  instruction.  This  is 
fine,  when  it  can  be  got;  besides  a  League  booklet 
Learning  the  Radiotelegraph  Code  that  can  help, 
ARRL  also  periodically  prints  a  list  of  clubs  that 
have  arranged  to  give  local  instruction  to  assist 
budding  amateurs.  But  it  is  no  occasion  to  de- 
spair if  completely  without  such  a  local  group. 
Many  of  the  best  operators  learned  their  Con- 
tinental by  listening.  It  is  important  in  getting 
started  to  listen  to  tape-sent  code  or  an  experi- 
enced operator  to  get  the  proper  sense  of  rhythm, 
or  the  spacing  of  characters  and  words  in  code 
work.  The  most  vital  thing  of  all  is  to  practice; 
stick  with  it  for  yet  more  practice.  Only  practice 
makes  progress  and  perfection  possible.  In  using 
WlAW's  daily  hour  of  practice  do  not  stop 
"writing  down"  at  the  speeds  you  can  com- 
fortably set  down  on  paper!  Copy  just  as  diU- 
gently  all  the  letters  you  can  get  at  higher  speeds. 
Use  the  bulletin  transmissions  in  the  earUer  or 
later  period  deUberately  to  get  what  you  can  at 
speeds  definitely  beyond  your  ability  to  make 
solid  copy!  Look  over  the  bands  and  spectrum 
between  the  amateur  bands  for  stations  that  are 
repeating  their  identification  or  calls. 

You  may  not  at  first  be  able  to  make  much  of 
this.  With  careful  listening  to  repeated  calls, 
however,  you  will  start  getting  a  letter  here  and

there,  till  finally  you  have  a  whole  transmission 
and  the  station's  identity.  It  is  bound  to  be  a 
big  thrill  to  ferret  out  this  pioneer  bit  of  intel- 
ligence, entirely  by  j^our  own  efforts !  Don't  over- 
look the  opportunity  to  hook  up  an  inexpensive 
oscillator  and  key  and  send  in  rhythm  with  the 
WlAW  tape,  too.  (Consult  the  monthly  QST 
announcement  of  the  Code  Proficiency  Program 
to  note  those  special  nights  when  we  give  the 
subject  of  the  practice  text.  With  that  in  hand 
you  can  send  in  step  with  the  transmitter  and 
perfect  your  rhythmic  responses.)  A  lot  of  re- 
ceiving practice  is  essential.  Highest  authorities 
in  this  field  of  learning,  however,  recommend  that 
at  least  25  per  cent  or  more  of  one's  time  be  spent 
in  sending  practice.  This  advances  the  general 
ability  to  coordinate  in  fast  recognition  of  all  the 
letters  and  aids  your  reception  as  well  as  sending 
ability.  The  whole  idea  in  amateur  radio  is  ' '  learn 
by  doing."  Once  you  can  memorize  and  buzz  the 
letters  locally,  most  anyone  can  learn  Continental 
just  by  regular  periods  of  tuning  in  and  getting 
the  essential  practice  on  the  stations  that  can  be 
tuned  in. 

Why?  (Echo  from  ARRL  DX  Test!)  P.  W. 
Watson,  ZL3GQ,  writes,  "May  I  say  how  much 
more  satisfactoiy  the  number  system  as  used  by 
the  Ws  in  your  DX  Test  was.  This  must  be  of 
inestimable  value  to  anyone  chasing  WAS. 
However,  I  have  one  minor  criticism  of  W/VE 
operating.  If  a  WVVE  receives  a  report  of  579 
to  599  I'd  estimate  95%  of  the  time  he  could  send 
the  exchange  once.  Wh^^  did  those  getting  such 
reports  send  their  number  three  times.'  .  .  .  And 
when  a  lower  S  report  was  given  even  send  it  four 
times!"  We  confess  we  can't  explain  this,  since 
in  our  poor  efforts  with  a  paltry  200  watts,  we 
never  had  to  use  more  than  a  single  repeat  as  an 
investment  against  a  time-consuming  additional 
transmission.  It  is  our  guess  that  some  operators 
have  never  reflected  that  the  "R5"  means  "per- 
fectly readable"  with  the  S7  to  9  indicating 
"moderately  to  extremely  strong  signals!" 

RACES  Insignia.  Until  recently  we  had  not 
heard  where  RACES  authorized  groups  could 
obtain  the  RACES  insignia  as  mentioned  in  this 
column  in  April  QST  and  as  illustrated  herewith. 
A  number  have  written  for  more  details  so  we 
quote  from  the  FCDA  memo  which  constitutes 
the  legal  background  and  the  detailed  description, 
"The  RACES  insigne  has  superimposed  on  the 
official  Civil  Defense  insigne  a  white  jagged  arrow 
edged  in  blue  resembling  a  flash  of  lightning, 
symbolic  of  space  radiation,  containing  the  in- 
scription 'RADIO'  in  blue  letters,  and  extending

circle  through  the  lower  lefthand  angle  of  the 
triangle.  Below  the  triangle  and  \A-ithin  the  blue 
circle  is  the  inscription  RACES  in  while  letters." 

W9UMS  wTites  us  that  their  c.d.  office  at 
Evansville,  Indiana  i.s  financing  their  group  to 
obtain  50  R.\CES  c.d.  emblems.  \V2BG0  advises 
that  the  Forbes  Products  Corporation,  625  So. 
Goodman  Street,  Rochester  20,  New  York  can 
supply  the  design  at  25  cents  each  in  lots  of  500.

APRIL  CD  QSO  PARTIES 

"One  of  the  best  spring  parties  on  record,"  were  senti- 
ments voiced  by  numerous  participating  ARRL  appointees 
and  officials.  ORS  W6BIP  found  activity  brisk  enough  on 
80  through  1.5  meters  for  him  to  grind  out  146,497  points 
and  leave  other  c.w.  competitors  in  his  wake,  while  New 
Mexico  ORS  W.iDWT  supplied  a  tougher  section  as  he  went 
about  accumulating  144,270  score-points.  W4YHD"s  shrewd 
handling  of  the  M.I.T.  set-up  likewise  resulted  in  a  husky 
tally  for  WIMX.  Sidelight:  W4KFC  took  part  for  just  a 
short  spell  but  reports  his  busiest  flurry  in  any  contest  to 
date;  73  QSOs  in  one  hour  of  3.5-Mc.  brasspounding.  .  .  . 
Despite  fierce  QRX  from  storms  and  rain  static,  P.\M/OPS 
W'4TV0  plied  40  and  7.5  for  a  dandy  20,825-pointer  to  edge 
the  'phone  brethren.  W9KDV,  with  W9VFY  doing  the 
talking  and  switch-throwing,  and  RM  WICRW  reached 
the  other  top  positions  with  scores  of  15,840  and  14,645 
points,  respectively.  Full  results  in  July  CD  Bulletin.

There  seems  to  continue  to  be  some  question  about  the 
relation  between  the  AREC  and  RACES.  Why,  we  wonder? 
On  a  good  many  occasions,  we  have  attempted  to  clear  this 
up,  but  in  some  places  there  is  still  conflict.  Who  causes 
the  conflict  is  a  detail,  but  it  takes  two  to  make  a  fight. 
Obstreperous  AREC  groups  on  the  one  hand,  and  a  cold, 
fishy  attitude  on  the  part  of  c.d.  people  on  the  other  hand 
can  cause  all  kinds  of  trouble.  They  are  matters  for  local 
resolution. 

ARRL's  official  view  of  the  relationship  is  that  the  two 
organizations  are  (i.e.,  should  be)  overlapping  and  inter- 
lacing —  in  some  places  identical.  We  are  not  ready  to  drop 
the  AREC  overboard,  for  several  reasons.  The  most  impor- 
tant one  is  that  we've  worked  hard,  we  amateurs,  for  the 
last  20  j'ears,  to  make  the  AREC  our  own  emergency  service 
organization,  and  we're  proud  of  it.  As  long  as  there  is  a 
need  and  use  for  it,  we  want  to  maintain  it  —  and  where 
no  particular  c.d.  program  exists,  there  is  plenty  of  need 
for  it. 

But  this  does  not  mean  that  the  AREC  wants  nothing  to 
do  with  RACES.  On  the  contrary,  long  before  there  was  an 
FCDA  heading  up  the  nation's  civil  defense  preparedness 
effort,  ARRL  officials  were  urging  that  radio  amateurs  be 
given  a  key  role  in  civil  defense  communications.  As  much, 
if  not  more,  than  any  other  group  or  individual,  ARRL  was 


Amateurs  of  the  Sioux  AinaU-ur  Radio  Assn.  have 
converted  this  bus  into  a  mobile  communications  cen- 
ter. Civil  Defense  and  Red  Cross  have  cooperated  in 
installing  transmitting  and  receiving  equipment,  a 
6500-watt  generator,  field  telephones  and  a  p. a.  system. 

an  active  midwife  at  the  birth  of  RACES.  We  think,  and 
have  thought  right  along,  that  the  AREC  is  the  natural  and 
logical  instrument  at  local  level  for  the  implementation 
of  RACES.  In  the  places  where  RACES  has  been  most 
successful,  it  has  been  just  this.  It's  one  of  the  things  that 
the  AREC  was  set  up  for:  to  serve  any  need  for  emergency 
communications  that  might  arise. 

Such  a  philosophy  will  not  embrace  the  premise  that 
precipitant  abandonment  of  all  previous  organization  for 
a  new  concept  is  a  desirable  course  of  action  to  follow.  You 
might  as  well  ask  the  telephone  and  telegraph  companies  to 
abandon  their  previous  organization  and  set  up  anew,  under 
new  leadership,  new  policies,  using  new  equipment.  It 
won't  work.  Full  use  of  existing  facilities  is  requisite,  both  to 
our  efficiency  and  our  economy.  The  AREC  is  an  existing 
facility.  It  is  flexible  enough  to  embrace  the  new  civil 
defense  function,  and  where  sufficiently  supported  can  (and 
has)  become  RACES.  The  EC  and  radio  oflticer,  if  they  are 
different  people,  must  work  together  toward  the  common 
civil  defense  end,  whether  they  care  for  each  other  per- 
sonally or  not.  AREC  members  must  sign  up  in  civil  de- 
fense. We  have  a  job  to  do  in  implementing  RACES. 
Civil  defense  has  a  job  to  do  in  utilization  of  the  amateur 


ser\'ice  for  communications  purposes.  Let's  stop  asking 
ourselves  and  each  other  foolish  questions,  and  get  the  job 
done! 

The  AREC  and  RACES,  at  top  level,  are  wedded  for  the 
duration.  This  state  of  wedlock  must  be  made  to  extend 
to  all  levels.  That's  the  job  of  you  fellows  on  the  ground 
floor,  so  get  a  firm  grip  on  your  prejudices,  personal  and 
otherwise,  and  let's  get  the  ceremony  under  way. 

A  snowplow  and  its  crew  got  stranded  in  a  blizzard  in  the 
wilds  of  Western  Nebraska  on  P'ebruary  19th,  and  W0AIN 
was  called  on  to  help  find  them.  He  contacted  W0LOD  in 
OgaUala  on  3525  kc,  since  telephone  lines  were  down  be- 
tween Ogallala  and  Lewellen,  and  relayed  the  information 
that  they  had  left  Lewellen  at  1700  on  the  19th.  I<ate  the 
next  afternoon  it  developed  that  the  men  were  safe.  W0AIN 
sent  this  word  to  W0LOD,  who  notified  their  families. 
Other  stations  participating:  W0s  ZAA  GEQ  UOB  BEN. 

When  a  telephone  cable  broke  down  between  the  La 
Crosse  (Wis.)  Municipal  Airport  and  Madison  on  February 
25th,  amateurs  filled  the  communications  gap  until  it  was 
repaired,  obtaining  weather  and  flight  information  from 
Madison  on  behalf  of  airport  officials,  CAA  and  the  Weather 
Bureau.  W9GPU  and  W90GT  held  down  the  La  Crosse 
end,  while  W900L  kept  contact  from  Madison.  Excellent 
publicity  was  received  on  television,  radio  and  the  newspaper 
on  this  bit  of  public  service. —  W9AKY,  EC  La  Crosse,

From  the  Ontario  SCM  we  have  gleaned  the  following: 
"We  would  like  to  commend  VE3UJ  who  tried  for  two  hours 
to  get  Sarnia  and  Chatham  Civilian  Defense  hooked  up 
during  the  windstorm  of  March  22nd.  The  Oil  City  Civil 
Defense  readied  two  trucks  to  dispatch  to  Chatham,  but 
the  efforts  of  VE3UJ  made  the  long  and  dangerous  trip  in 
grim  weather  unnecessary.  Appreciation  from  c.d.  officials 
is  extended  also  to  VESs  AWQ  LB  DIJ  DZ  and  MW. 
Traffic  for  the  London  Free  Press,  civil  defense  and  police 
officials  was  handled  due  to  wire  facilities  being  out.  VE3EI 
and  VE3BVM  also  exchanged  important  traffic. 

A  severe  train  accident  near  Albany,  N.  Y.,  was  the 
occasion  for  some  creditable  work  turned  in  by  amateurs 
of  the  Capital  Area  Radio  Emergency  Net  on  April  2nd. 
W2E0M  and  K2ACB  flashed  word  of  the  emergency  and 
within  a  few  minutes  six  mobiles  were  proceeding  to  the 
scene.  K^CWX  assumed  net  control.  Of  the  six  mobiles, 
W2EOM,  W2SZ,  K2AYH  and  KN2IUE  arrived  at  the 
scene.  KN2JHY  was  turned  back  by  police,  and  W2FEN 
set  up  in  Castleton  to  act  as  a  relay  station.  K2AYH, 
W2SE  and  KN2IUE  placed  their  cars  at  strategic  locations 
while  W2E0M  took  his  portable  down  to  the  wreck. 
Stations  on  the  "home  front"  were  W2s  AWF  DIF  TMM 
and  K^s  BUY  (operated  by  W2GTZ)  ACB  and  GAZ.  The 
net  was  conducted  in  an  efficient  and  businesslike  manner 
throughout.  Much  informal  traffic  was  handled  and  one 
formal  message  was  relayed  out  of  the  area  via  K2BUV. 
Much  credit  for  the  operation  goes  to  the  NCS,  K2CWX, 
at  the  Veterans  Hospital. 

The  Smoky  Mountain  Amateur  Radio  Club  in  April 
organized  a  network  to  furnish  radio  assistance  to  the 
Maryville  (Tenn.)  Police  Department  when  this  com- 
munity was  left  without  adequate  emergency  telephone 
service.  W4BXG  (EC  for  Blount  County)  reports  the 
following  stations  active:  W4s  AM  A  BXQ  FEP  JSP  OKD 
NLJ  TZB  VSS  VTT  ZEN  ZSI  QCZ  FHT,  KN4s  AAO 
AAV  COF  CRY,  and  W5ILR/4.  These  stations  manned  net 
facilities  consisting  of  fixed  and  mobile  unit*  on  two  and 
160  meters.  For  23  days,  police  traffic,  medical  and  other 
matters  were  handled  as  emergency  radio  communications. 

YE5LU,  SEC  Saskatchewan,  reports  that  landlines  were 
out  in  the  blizzard  that  hit  southwestern  Saskatchewan 
April  3rd.  Amateurs  assisted  in  restoring  communications 
for  the  power  companies,  VE5TV  and  VE5LU  maintaining 
schedules  three  times  daily  through  April  6th.  Others 
participating:  YE4AI,  VESs  BO  TV  CM  BH  RU  CX  MS 
LU  and  RE. 

The  Texoma  Amateur  Radio  Club  was  called  into  action 
for  emergency  operation  when  a  tornado  struck  Sherman, 
Texas,  on  April  6th  at  0245,  disabling  telephone  and  power

QST  for 


circuits.  Tlie  first  mobile  was  on  the  air  at  0415,  a  net 
control  station  with  auxiliary  power  having  previously  been 
set  up.  The  civil  defense  radio  unit  operated  three  field 
stations  and  four  mobile  stations  several  hours  following 
the  storm  with  one  out  of  town  trip  to  Perrin  AFB  for 
additional  fire-fighting  apparatus  for  Gunter.  The  work  of 
the  amateurs  participating  was  highly  commended  by  the 
civil  defense  director  and  assisting  auxiliary  police  chief. 
Those  participating  were  W5s  UTB  IDZ  POG  LDG 
SGR    DGG    and    UIQ.         —  W6UTB,  EC  Sherman,  Tex. 

The  snowstorm  that  hit  western  Nebraska  on  April  12th 
took  the  town  of  Potter  out  like  a  light  —  literally.  Potter 
had  no  electric  power  for  two  nights,  and  communication 
lines  were  down,  too.  W0KQX  started  his  putt-putt  in  his 
snow-covered  back  yard  and  made  contact  with  W0UOB, 
in  Sidney,  to  provide  the  only  communications.  He  was 
able  to  tell  Sidney  that  no  special  emergency  measures  were 
required,  althougii  many  Potter  residents  were  suffering 
from  cold.  Tlie  communications  situation  was  returned 
to  normal  on  April  13th. 

On  April  17th,  a  distress  call  from  W6GRU/m  was  beard 
on  the  American  Legion  Amateur  Radio  Net  frequency 
(3975  kc).  He  gave  his  location  as  the  Donner  Pass  road 
east  of  Sacramento,  where  the  snow  had  reached  18  inches, 
resulting  in  blocked  highways.  Traffic  was  heavy  due  to 
the  North  American  Ski  Championships  being  held  in  the 
area.  W6GRO  took  over  the  net,  with  W6EPB  assisting, 
and  contacted  the  California  Highway  Patrol  to  start 
relief  equipment  on  the  way.  The  experience  gained  in  the 
Tehachapi  earthquake  proved  invaluable.  An  amateur 
employed  by  the  California  Highway  Patrol  (call  unknown) 
set  up  a  station  in  the  office  and  maintained  contact  w'ith 
W6GRU/m  until  relief  arrived  about  2240.  K6EJT  and 
K6ECP  maintained  control  with  W6GRU/m  until  he 
reached  Sacramento.  Also  active  were  W6s  QMO  CNA 
OFJ  and  IDY.  This  incident  rated  blare  headlines  in  the 
Los  Angeles  Times  for  April  18th.

The  Alabama  Emergency  Net  P  was  alerted  at  2200  on 
April  23rd  during  a  tornado  warning  for  Northern  Alabama. 
The  alert  lasted  until  0230  April  24th.  W4s  HKK  TKL 
AZX  and  ZSQ  took  turns  as  NCS.  Traffic  was  handled  for 
the  Tennessee  Valley  Authority  to  participate  in  the  search 
for  a  lost  boat  on  the  Tennessee  River.  Other  stations  par-

On  May  3rd,  a  heavy  snowstorm  hit  Saskatoon,  Sask. 
The  wet  snow  clung  to  everything  it  liit,  and  soon  telephone 
and  electric  wires  and  poles  were  bending  and  snapping 
under  the  weight.  At  1730,  VEoLM  called  VE5BG  to 
relay  a  message  to  the  'phone  company  that  his  telephone 
was  out.  W5RE  also  was  without  telephone  communica- 
tions. VE5DR  was  asked  by  the  civil  defense  director  to 
arrange  communications  for  the  power  company.  This  he 
did,  and  VE5DR  and  VE5EH  went  to  the  local  club 
station  set-up  at  c.d.  headquarters.  There  they  found  the 
antenna  down.  After  repairing  tliis,  the  power  went  off; 
so  they  took  a  portable  power  plant  to  the  VE5DR  location 
and  were  soon  on  the  air. 

This  was  the  beginning  of  a  busy  time  for  the  amateurs. 
VESs  DN,  DG  and  RE  were  kept  busy  handling  messages 
for  the  power  company,  which  was  in  dire  straits,  and  later 
the  railroads  called  on  the  amateurs  to  help  them  with  some 
of  their  communications.  Schedules  were  maintained  from 
VE5DR  (with  VE5EH  assisting)  all  through  Tuesday 
night.  VE5JG  at  Regina  also  came  on  the  air,  staying 
until  0200.  VEos  DN  and  RE  remained  operative  through- 
out the  night.  On  Wednesday  morning  (May  4th),  VE5CM 
was  on  from  Regina  and  remained  all  day.  VE5WW  also 
was  on  from  VEoDG,  and  VE5JP  did  some  verj'  valuable 
relay  work.  VEoBLT  operated  on  emergency  power  for  a 
while,  but  ran  out  of  gas.  VE5BG  took  over  from  VE5DR 
at  0830  Wednesday,  later  assisted  by  VESs  BD  RL  and 
DU.  VE5VL  was  on  stand-by.  VESs  FY  and  YF  sent  and 
received  news  dispatches  to  the  outside  by  tape  recorder, 
since  normal  news-dispatching  agencies  were  without 
communications.  Helping  out  in  this  news  coverage  were 
VESs  JP  YJ  RB  VD  DD  and  WW.  Considerable  traffic 


was  handled  during  the  day  by  VE5DR,  who  later  made  a 
radio  broadcast  via  amateur  radio,  VE5DR  to  VE60D. 
VE5HR  was  in  the  hospital  and  unable  to  be  active,  but 
supplied  us  with  all  the  above  data. 

Sixteen  SEC  reports  were  received  for  March  activities, 
representing  5356  AREC  members:  Miim.,  S.  Dak.,  Ky., 
Tenn.,  Maritime,  Ga.,  Wash.,  W.  N.Y.,  E.  Fla.,  N.Y.C.- 
L.I.,  Ore.,  Wise,  San  Joaquin  Valley,  E.  Bay,  Los  A.,  Ont. 
The  Los  Angeles  SEC  reports  1424  AREC  members  in  his 
section,  and  claims  this  to  be  the  highest  in  the  United 
States,  by  plenty.  The  number  increases  a  little  each  month. 
So  far,  no  one  even  comes  close  to  this  number,  N.Y. C.- 
L.I, being  second  with  742. 

RACES  News 

From  FCDA,  we  have  the  latest  info  (May  17th)  on 
states  having  fully-approved  RACES  plans.  We  thought 
this  would  be  of  interest  to  you.  The  fol- 
lowing are  fully  approved  for  RACES: 
Alabama,  California,  Colorado,  Con- 
necticut, Delaware,  Georgia,  IlUnois, 
Kansas,  Louisiana,  Maryland,  Massa- 
chusetts, Michigan,  Missouri,  Nebraska, 
Nevada,  New  Jersey,  New  Mexico,  New 
York,  Ohio,  Oklahoma,  Oregon,  Pennsyl- 
vania, Rhode  Island,  Tennessee,  Ver- 
mont, Virginia,  Washington,  West  Virginia,  Wisconsin, 
Alaska,  Hawaii,  D.C.  Now  being  processed  are  the  state 
RACES  plans  for  Florida,  Minnesota,  North  Carolina  and 
Wyoming.  Not  yet  heard  from  are  Arizona,  Arkansas,  Idaho, 
Indiana,  Iowa,  Kentucky,  Maine,  Mississippi,  Montana, 
New  Hampshire,  North  Dakota,  South  Carolina,  South 
Dakota,  Texas  and  Utah.  Thus,  29  states,  two  territories 
and  D.C.  now  have  approved  RACES  plans,  and  by  the 
time  you  read  tliis  the  chances  are  good  that  four  more  will 
have  been  approved.  RACES  organizers  in  the  states  men- 
tioned above  as  "not  yet  heard  from"  should  get  the  ball 
rolling  toward  their  state  RACES  plan,  if  possible.  The  time 
to  do  this  is  now,  not  after  the  bomb  falls. 

One  place  where  they  have  successfully  combined  the 
AREC  and  RACES  is  Steubenville,  Ohio,  where,  under 
EC/RO  W8ERR,  this  group  had  the  second  FCC-approved 
RACES  plan  in  the  state.  The  main  control  is  located  in 
town,  but  there  is  also  an  alternate  control  station  seven 
miles  out  of  town.  A  22-foot  house  trailer  is  being  equipped 
as  a  mobile  alternate  control  station.  The  call  used  for 
RACES  is  W8ERR. 


In  St."  Lambert,  Que.,  amateurs  are  alerted  for  civil 
defense  by  the  police  station,  which  receives  the  warning 
from  the  Air  Defense  Command,  RCAF.  Only  EC  VE2KG 
is  called.  He  then  calls  two  other  amateurs,  each  of  whom 
call  two  additional  amateurs  until  all  personnel  are  alerted. 
This  process  makes  it  possible  to  notify  all  personnel  within 
six  minutes  after  receipt  of  the  alert. 

^M  ••  •   M- 

We  don't  believe  we  have  previously  recorded  the 
presence  on  the  FCDA  staff  of  another  amateur.  He  is 
Jim  MacGregor,  W8DUA,  formerly  in  charge  of  Kalamazoo 
Police  Radio  and  a  staff  member  of  WOOD-TV  in  Grand 
Rapids.  Mac  visited  us  in  connection  with  the  April  30th 
Region  I  Test,  and  will  work  with  Charlie  Dewey,  W8LBM 
(see  April  QST,  p.  73),  on  RACES.  It  is  good  to  know 
that  we  will  have  two  active  amateurs  on  the  FCDA  Staff 
so  intimately  concerned  with  the  processing  of  RACES 
applications  and  RACES  implementation  on  a  national 
scale.  We  hope  that  their  presence  will  have  a  salutary 
effect  on  the  progress  of  RACES  at  all  levels. 

From  Key-Klix,  publication  of  the  Santa  Barbara 
Amateur  Radio  Club,  we  glean  the  information  that  the 
Santa  Barbara  RACES  plan  has  been  approved  by  FCDA 
as  of  March  21st,  the  first  approved  plan  in  California 
C.D.  Region  Seven.  This  was  the  result  of  "three  years' 
intensive  spadework  by  c.d.  officials  in  this  area,"  says 
the  bulletin.  Frequencies  to  be  used  are  29,550,  29,470, 
145,460,  145,500  and  147,240,  crystals  for  which  will  be 
furnished  authorized  amateurs.  K6BVA  is  the  call  that  will 
be  used  by  all  stations.  Says  the  editor;  "Key-Klix  will  keep 
you  posted  as  the  red  tape  is  unravelled."

MEET  THE  SCMs 

Edward  F.  Conyngham's  interest  in  radio  dates  back 
to  his  early  childhood  when  he  heard  all  the  wonderful 
accounts  of  how  the  operator  on  the  SS  Titanic  sent  out 
messages  reporting  the  disaster.  A  few  years  later  an  ex- 
Na\-j'  operator  gave  him  first-hand  information  on  the 
workings  of  radio  and  in  1934  he  was  issued  his  first  license. 

W7ESJ  is  housed  in  a  special  room  and  transmitting 
equipment  is  comprised  of  a  Navy  TBW-3,  803  final;  a 
Navy  GP-7  modified,  803  final;  a  Navy  TCS-12,  pair  of 
1625s  final;  a  Viking  II;  an  Elmac  AF-67;  a  Lysco  600; 
and  a  homemade  rig  with  a  pair  of  46s  in  the  final.  Re- 


ceivers are  an  S-76,  a  BC-342,  an  Elmac  PMR-6A,  and 
three  Command  receivers  for  monitoring.  Antennas 
regularly  used  are  an  80-meter  half-wave,  center  fed 
with  open- wire  line;  a  100-ft.  Marconi;  and  a  50-ft.  Marconi. 
For  emergencies  a  PE-108  a.c.  generator  is  used  to  power 
the  Elmac  and  TCS  transmitters. 

Since  his  election  as  Oregon's  SCM,  Connie  has  re- 
linquished his  appointments  as  Official  Observer  and 
Section  Emergency  Coordinator,  but  has  retained  the  post 
of  Official  Relay  Station.  He  has  been  issued  Public  Service 
certificates  for  his  assistance  in  Columbia  River  and 
other  emergencies  and  also  has  Rag  Chewers  Club,  Old 
Timers  Club,  and  Code  Proficiency  certificates,  the  latter 
for  35  w.p.m.  While  on  a  destroyer  in  1939  he  was  clocked 
for  IJ.^  hours  receiving  press  at  52  w.p.m.  He  holds  member- 
ship in  the  Portland  Amateur  Radio  Club  and  the  Amateur 
Radio  Association  of  Bremerton  and  is  an  enthusiastic 
participant  in  the  monthly  on-the-air  parties  for  League 
Officials. 

A  retired  Navy  man,  Connie  enjoys  skiing,  sailing,  row- 
ing, and  watching  baseball.  His  other  hobbies  are  cartooning 
and  drawing  (the  picture  shown  here  is  self-drawn). 

TRAFFIC  TOPICS 

We  traffic  men  have  a  tough  row  to  hoe  during  the  sum- 
mer months.  The  QRN  gets  worse,  the  days  get  longer, 
other  activities  get  in  the  way  of  nets  and  schedules,  and  on 
a  national  basis  "daylight  saving"  time  makes  a  mess  of 
our  NTS  time  schedule.  Nets  lose  personnel  while  operators 
go  on  vacations.  It's  a  tough  time  of  the  3'^ear  for  organized 
traffic  handling,  and  many  have  asked  us  why  we  try  to  keep 
going  at  all,  why  we  don't  close  up  shop  in  May  until 
October. 

That's  a  fair  question,  and  it  deserves  a  fair  answer. 
After  all,  isn't  it  true  that  most,  if  not  all,  of  us  traffic  men 
handle  traffic  because  we  like  it?  Never  mind  why  we  like  it 
—  we  just  do.  Do  we,  then,  enjoy  it  during  the  summer 
months,  with  lightning  playing  around  our  antennas,  with 
weak  signals  and  the  crash  of  static  in  our  ears?  Are  we  realhj 
nuts? 

Let's  ignore  that  last  question  as  an  interesting  but  some- 
what irrelevant  matter  of  conjecture,  and  get  at  the  one 
before  it.  We  think  that  the  traffic  man  who  persists  in  his 
efforts  to  handle  traffic  when  the  going  is  rough  does  so 
because  he  finds  challenge  in  it,  and  meeting  this  challenge 
is  a  form  of  enjoyment.  Handling  traffic  under  unfavorable 
operating  conditions,  whether  they  be  atmospheric,  propa- 
gational  or  environmental,  is  something  we  would  certainlj- 
have  to  do  in  a  national  emergency.  Those  who  meet  the 
challenge  of  doing  so,  for  whatever  reason,  are  the  ones  who 
will  be  the  mainstays  in  any  national  emergency,  while 
those  who  throw  up  their  hands  and  quit  during  the  tough 
season  will  find  themselves  severely  handicapped  by  lack  of 
experience  when  the  chips  are  down.  So  we  offer  this  salute 
to  those  of  the  traffic  gang  who  are  still  in  there  pitcliing, 
making  our  amateur  traffic  service  a  year-around  service 


instead  of  a  "fair  weather"  plaything.  Our  hats  are  off  to 
you,  fellows! 

Miscellaneous  reports:  (1 )  W  JsAMH  reports  a  traffic  total 
of  837  for  the  Early  Bird  Transcontinental  Net  for  April, 
eleven  stations  participating.  (2)  The  New  York  State  Phone 
Emergency  and  Traffic  Net  handled  255  messages  in  April, 
with  1114  stations  participating,  according  to  W2GSS.  (3) 
WILYL  reports  678  messages  for  the  First  Call  Area  Section 
of  the  Transcontinental  Phone  Net,  with  15  stations  par- 
ticipating. (4)  The  College  Net  had  eight  meetings,  handled 
18  messages;  62  stations  called  in. 

National  Traffic  System.  Recentlj-  someone  asked  us  about 
the  general  quality  of  our  NTS  leadership  personnel.  We 
replied  that  they  were  all  good,  and  some  were  better  than 
others.  That's  exactly  the  way  we  feel  about  it,  too.  There 
isn't  a  poor  manager  in  the  whole  of  NTS,  and  never  was. 
Managing  an  NTS  section,  regional  or  area  net  is  no  kid's 
game;  neither  does  the  job  get  harder  or  more  important  as 
you  go  up  in  level  —  if  anything,  managing  a  bunch  of 
finished  traffic  men  (such  as  those  at  regional  or  area  level)  is 
easier  tlian  doing  the  same  at  section  level,  where  training 
has  a  more  important  role. 

You  fellows  who  participate  in  NTS  owe  it  to  your  net 
manager  to  do  your  best  to  help  him  out.  Volunteer  for  as- 
signments needed,  criticize  freely  but  constructively,  and  be 
on  deck  as  often  as  you  can  when  the  net  meets.  It's  your 
net  as  well  as  his.  Your  participation  is  not  particularly 
benefiting  him,  or  ARRL,  or  even  yourself;  it's  benefiting 
all  of  amateur  radio  as  well.  Keep  this  in  mind,  and  remem- 
ber also  that  the  net  manager  needs  your  help,  ad\-ice  and 
interest.  Don't  leave  everj'thing  to  him,  tlien  blame  him 
when  the  net  stagnates.  It's  up  to  you,  too.

W4BVE  has  accepted  the  4RN  managership,  so  we  can 
begin  to  look  for  increased  activity  from  that  quarter. 
RN5,  under  the  managership  of  W40GG,  exceeded  their 
previous  record  of  April  traffic  (442)  by  so  much  that  it 


Dave  Goggio,  ^  40GG,  energetic  manager  of  the  Fifth 
Regional  Net  (RI\5)  of  NTS,  relaxes  at  his  operating 
position.  Dave  has  rejuvenated  R]N5  from  low  ebb  into 
one  of  the  hottest  regional  nets  in  INTS.

QST  for 


"ain't  funny."  Dave  is  doing  a  super  job  of  getting  the 
RN5  sections  organized,  and  getting  a  lot  of  support  from 
everywhere  but  Southern  Texas.  W6ZRJ  is  the  new  manager 
of  RN6,  replacing  W6JOH;  let's  give  Doc  plenty  of  support. 
VE7ASR  is  making  a  big  effort  to  get  100%  representation 
of  sections  in  I^iN7,  but  it's  not  easy.  W9UNJ  is  resigning  as 
9RN  Manager  as  soon  as  a  replacement  can  be  found.  TRN 
has  adopted  a  thrice-weekly  schedule  for  the  summer,  but 
will  endeavor  to  continue  100%  liasion  with  EAN.  PAN  is 
going  great  guns,  but  Manager  W7APF  is  having  TVI 
troubles. 

Transcontinental  Corps.  No  report  from  Central  Area  this 
month.  W8UPB  reports  for  Eastern  Area  that  most  sched- 
ules are  holding  together,  but  there  are  some  significant 
vacancies.  Pacific  Area  is  doing  excellently,  but  now  that 
W6HC  is  an  ARRL  Director  he  feels  that  he  cannot  con- 
tinue as  TCC  Director,  so  there  will  be  a  new  TCC  Pacific 
Area  Director  soon. 

AMATEURS  SCORE  IN  TELETHONS 

We  have  eight  reports  of  amateurs  participating  in 
telethons  connected  with  the  Marcli  of  Dimes  early  in 
1955.  Let's  summarize  each  one  briefly,  in  chronological 
order  except  that  dateless  reports  come  last. 

1)  The  Panliandle  Amateur  Radio  Club  of  Amarillo 
assisted  in  the  March  of  Dimes  Telethon  in  that  area, 
which  started  m  mid-January.  Eighteen  amateurs  in  the 
area  participated,  handling  1792  messages  and  collecting 
contributions  or  pledges  for  more  than  $7600. 

2)  Seventeen  members  of  the  Cascade  Net  of  Portland, 
Ore.,  were  among  the  participants  in  tlie  special  March 
of  Dimes  drive  .January  21st-22nd.  A  transmitter  at  the 
KOIN-TV  studios  was  set  up  and  operated  during  a  special 
4J^-hour  program.  As  viewers  telephoned  their  pledges, 
W7AEF  at  tlie  studio  set-up  called  the  nearest  of  19  mobiles 
spotted  throughout  tlie  city,  which  then  proceeded  to  make 
the  collections.  During  the  period,  the  mobiles  picked  up  a 
total  of  $2215.82. 

3)  In  Broward  County,  Fla.,  fixed  stations  in  amateurs' 
residences  were  used  to  radio  dispatch  mobiles  as  the  calls 
poured  in  over  broadcast  and  TV  stations.  Thirty  home 
stations  and  15  mobiles  were  active  in  this  operation  on 
January  29th-30th. 

4)  In  Nashville,  Tenn.,  Operation  Poliothon  was  a 
combination  AREC  workout  and  a  public  service  venture 
of  Nashville  and  Davidson  County  amateurs.  Free  time 
was  furnished  by  WLAC-TV  for  the  full  period  of  the 
Telethon  from  2200  January  29th  to  1300  January  30th.  As 
telephone  pledges  were  received,  a  mobile  would  go  out 
with  a  member  of  the  Junior  Chamber  of  Commerce, 
sponsors  of  the  Telethon.  Nineteen  ten-meter  mobiles  were 
used  during  the  operation,  with  six  fixed  stations  scattered 
around  the  city  as  relay  stations  whenever  the  need  arose. 

5)  The  Owensboro  (Ky.)  Amateur  Radio  Club  supplied 
transportation  and  communication  for  the  "Mothers' 
March  Against  Polio"  in  that  area,  covering  Henderson 
and  Evansville  in  addition  to  Owensboro.  A  base  station 
was  set  up  at  Mothers'  March  headquarters,  and  mobiles 
dispatched  to  make  collection  whenever  a  telephone  pledge 
was  received.  Amateurs  also  conducted  communications 
from  the  various  schools  at  which  the  Mothers'  March  had 
its  headquarters. 

6)  On  February  18th,  the  Calgary  Radio  Emergency 
Net  assisted  the  Canadian  Legion  in  a  polio  drive.  The 
local  radio  station  CKXL  broadcast  a  4-hour  program 
calling  for  telephoned  bids.  These  bids  were  relayed  on 
75  meters  to  hamshacks  around  the  town  where  the  Legion 
had  stationed  cars,  which  were  then  sent  around  the 
district  to  pick  up  the  donations.  About  $4000  was  collected 
for  the  fund.  Fifteen  amateurs  participated  from  seven 
stations  in  Calgary. 

7)  We  don't  know  the  date  of  the  telethon  in  Longview, 
Texas,  but  word  from  W5AFR  via  SCM  W5JQD  is  that 
the  Long\iew  Amateur  Radio  Club  and  other  amateurs  in 
the  district  assisted  in  communications  between  various 
county  headquarters  and  KTVE.  Operation  was  on  160 
and  80  meters,  with  six  amateurs  at  the  TV  station,  for  21 
hours.  Donations,  says  W5AFR,  were  around  $22,000. 

8)  In  Bangor,  Maine,  mobiles  of  the  Bangor  Civil 
Defense  Corps  assisted  in  supplying  communications  for 
the  Mothers'  March  in  Bangor  and  Brewer.  The  mobiles 
were  stationed  at  strategic  points,  with  a  control  station 
dispatching  them  to  points  in  the  two  cities  as  needed. 
Twelve  amateur  mobile  units  assisted  in  this  operation.

BRIEF 

The  Connecticut  'Phone  Net  is  finding  certain  informa- 
tion made  available  by  the  telephone  company's  central 
and  regional  offices  most  valuable.  For  delivery  of  radio 
traffic  the  NCS  and  many  net  members  are  using  the  publi- 
cation Connecticut  Localities  Teleplione  Exchanges,  available 
to  subscribers  on  request.  This  lists  all  Connecticut  towns 
and  under  what  main  city  exchanges  they  come.  Another 
helpful  publication  is  Central  Office  Names,  also  free  on  re- 
quest from  the  New  Haven  office  of  the  Southern  New  Eng- 
land Telephone  Company.  WILIG  suggests  that  traffickers 
in  other  parts  of  the  nation  secure  parallel  publications  to  aid 
in  delivery  of  radiograms. 

DXCC  NOTES 

Our  DXCC  Note  this  month  will  clarify  the  case  of  Corn 
Islands  with  regard  to  our  DXCC.  QSLs  for  Corn  Islands 
count  for  Nicaragua  only.  Information  curently  originating 
with  the  United  States  Department  of  State  indicates  Corn 
Islands  are  solely  under  the  administration  of  Nicaragua. 
Our  FCC  is  fully  cognizant  of  the  position  taken  by  the 


Department  of  State.  Therefore,  any  QSL  submitted  for 
DXCC  credit  from  Corn  Islands  must  be  viewed  with  at- 
tention to  Rule  #7  of  the  DXCC  rules  which  provides  that 
only  the  calls  issued  by  the  administrating  government  or 
licensing  authority  will  be  recognized. 

The  question  of  the  distance  of  the  Corn  Islands  from 
Nicaragua  was  raised  in  some  correspondence.  In  view  of 
these  being  only  35  miles  removed  from  the  parent  country 
there  would  be  no  adequate  precedent  to  justify  country 
status  on  the  basis  of  distance.  (See  page  68,  May  QST, 
Country  Considerations,  point  2.) 

CODE-PROFICIENCY  PROGRAM 

Twice  each  month  special  transmissions  are  made  to 
enable  you  to  qualify  for  the  ARRL  Code  Proficiency  Cer- 
tificate. The  next  qualifying  run  from  WIAW  will  be  made 
on  July  11th  at  2130  EDST.  Identical  texts  will  be  sent 
simultaneously  by  automatic  transmitters  on  1885,  3555, 
7125,  14,100,  21,010,  52,000  and  145,600  kc.  The  next  quali- 
fying run  from  W60WP  only  will  be  transmitted  on  July 
2nd  at  2100  PDST  on  3590  and  7138  kc. 

Any  person  may  apply;  neither  ARRL  membership  nor 
an  amateur  license  is  required.  Send  copies  of  all  qualifying 
runs  to  ARRL  for  grading,  stating  the  call  of  the  station  you 
copied.  If  you  qualify  at  one  of  the  six  speeds  transmitted, 
10  through  35  w.p.m.,  you  will  receive  a  certificate.  If  your 
initial  qualification  is  for  a  speed  below  35  w.p.m.,  you  may 
try  later  for  endorsement  stickers. 

Code-practice  transmissions  will  be  made  from  WIAW 
each  evening  at  2130  EDST.  Speeds  are  15,  20,  25,  30  and 
35  w.p.m.  on  Monday,  Wednesday  and  Friday,  and  5,  7J^, 
10  and  13  w.p.m.  on  Sunday,  Tuesday,  Thursday  and 
Saturday.  Approximately  10  minutes'  practice  is  given  at 
each  speed.  References  to  texts  used  on  several  of  the 
transmissions  are  given  below.  These  make  it  possible  to 
check  your  copy.  For  practice  purposes  the  order  of  words 
in  each  line  of  QST  text  sometimes  is  reversed.

the  13th  BPL  for  DO.  DKW,  formerly  of  the  Starved 
Rock  Club,  now  has  plenty  of  room  for  skywires,  he  writes 
from  Prescott,  Ariz.,  and  will  be  on  40  meters  soon.  ABS 
is  talking  about  getting  on  the  air  from  the  new  QTH  in 
Rock  Island.  LIG  is  enjoying  20  meters  after  more  than  a 
year's  absence.  K4ATN  visited  Vice-Director  QLZ,  ZEN, 
and  many  others  of  the  down-State  gang.  ZEN  hopes  by 
this  time  to  have  his  cruiser  launched  on  the  Illinois  River. 
PHE  had  frequency  drift  in  the  rig  but  eliminated  it  with 
the  help  of  IFA.  Now  he  is  going  to  tackle  repairs  to  the 
beam.  FRP  has  moved  his  shack  into  a  new  trailer  home. 
USI  now  puts  out  Official  Bulletins  on  40,  6  and  2  meters 
as  band  activity  indicates.  IDA  now  is  on  s.s.b.  and  likes 
the  s.s.b.  session  of  lEN  each  Wed.  at  1730.  PVD  obtained 
a  35-foot  pole  for  a  skywire.  SKR  is  busy  trying  to  eliminate 
chirp  in  the  BC-459.  Novice  JZK  has  a  new  Globe  Scout. 
New  Novice  calls  are  PGB  and  NST.  BA  has  been  busy 
organizing  a  back-up  net  in  Belleville  for  the  city  police; 
now  the  sheriff  wants  the  same  thing.  HUX  has  his  vertical 
perking  and  likes  it.  Congrats  to  BRD  and  his  XYL  on  the 


arrival  of  a  second  jr.  operator.  If  it's  a  contest  you  are  lis- 
tening to  you  always  hear  GDI,  while  his  brother  LI  hardly 
ever  stirs  from  20  meters.  Both  KJ  and  BUK  now  have  their 
kw.  rigs  going  and  BUK  won  his  fight  with  the  Evanston 
village  fathers,  who  finally  gave  him  permission  to  erect  a 
60-foot  tower.  EVA  says  we  insulted  him  last  month  when 
we  associated  him  with  a  teletypewriter.  It's  a  teleperfora- 
tor,  he  says,  which  sends  out  dots  and  dashes.  HP.J,  one  of 
the  leading  f.m.  exponents,  was  heard  on  a.m.  and  working 
off  the  frequency  of  147.5  Mc.  UZ  deplores  the  fact  that  so 
many  new  General  Class  licensees  rush  to  build  modulators. 
The  Cenois  Amateur  Radio  Assn.  gets  out  an  interesting 
news  letter.  Officers  of  the  group  are  MUD,  TLE,  and  UFR. 
C.d.  seems  to  be  picking  up.  SEC  HOA  announced  the  is- 
suance of  EC  certificates  to  GLR,  BLO,  EAD,  SXU,  VSX, 
MRT,  and  NGG,  all  active  hams.  NGG  incidentally  works

(  A^o.  G  of  a  St'ritut} 


"More  Roads  to  Rome  Than  One" 

kJELECTiviTY  in  the  last  few  years  has  become  more  and  more  of  a  major  interest  to  the  radio  amateur, 
not  only  from  a  theoretical  discussion  but  also  from  a  practical  operating  standpoint,  because  of  the 
recent  advent  of  at  least  three  manufactured  receivers  offering  a  degree  of  selectivity  that  was  unob- 
tainable at  almost  any  price  just  a  few  years  ago. 

1  HE  theoretical  analysis  and  mathematical  tools  to  develop  narrow  passband  systems  are  not  basically 
new,  having  been  first  presented  in  text  form  by  Shea  in  1929.  Shea's  original  work  covered  filters  only 
from  an  electrical  standpoint,  but  from  his  concepts,  others  (such  as  Mason  in  1942)  have  developed 
low-pass,  high-pass  and  band-pass  networks  for  acoustic  and  mechanical  systems.  Today,  therefore,  the 
electronic  engineer  has  quite  a  few  choices  as  to  the  method  of  achieving  the  selectivity  requirements  of 
the  customer. 

XN  a  theoretical  radio  receiver,  the  ideal  location  for  all  the  selectivity  is  directly  after  the  antenna  and 
before  the  first  tube  of  the  receiver.  .\s  yet,  no  one  knows  a  practical  method  of  obtaining  the  required 
high  order  of  selectivity  that  is  also  tunable  over  a  wide  band  of  frequencies.  Hence  the  practical  re- 
ceiver obtains  some  selectivity  in  successive  stages  by  variable  tuned  circuits  until  the  signal  is  converted 
to  a  convenient  fixed  intermediate  frequency  at  which  point  the  maximum  and  final  selectivity  is 
obtained. 

a/UT  the  I.F.  frequency  the  designer  has  the  choice  of  only  two  basic  systems  and  each  is  composed  of 
resonant  elements:  the  first  —  clr-ctrical  resonance  and  the  second  —  mechanical  resonance.  To  some 
it  may  seem  somewhat  strange  if  quartz  crystals  are  used  in  the  filter;  the  filter  should  be  properly 
described  as  a  "mechanical  filter"  as  the  piezo-electrical  properties  of  quartz  actually  cause  a  change 
in  the  shape  of  the  filter  clement  and  therefore  the  crystal  is  mechanically  vibrating  at  some  specific 
frequency. 

T^iiE  corollary  can  be  drawn  that  other  materials  exhibiting  similar  characteristics,  such  as  the  magneto- 
striction effect,  could  also  be  employed  as  filter  elements.  However,  magneto-striction  effect,  at  present, 
is  used  mainly  for  transducer  elements  in  certain  mechanical  filters.  Certain  Ferro-ceramic  compounds 
are  useful  in  filters  only  because  of  this  magneto-striction  effect. 

x'oR  most  amateur  work  it  is  a  practical  necessity  that  the  degree  of  selectivity  be  varied  over  a  fairly 
wide  range  to  encompass  different  modes  of  transmission  and  different  band  conditions.  Thus  the 
design  engineer  is  now  faced  with  another  decision:  Which  of  the  two  basic  types  of  filter  systems  will 
meet  the  customer  requirements  better  and  still  be  economically  practical?  Of  even  greater  importance, 
which  of  the  two  systems  is  worthy  of  further  research  for  possible  application  to  amateur  receivers  and 
transmitters? 

a/UT  the  present  state  of  the  art  the  only  system  whose  passband  can  be  varied  over  the  necessary  range 
without  complete  substitution  of  a  new  network  is  the  "electrical."'  The  mechanical  systems  offer  some- 
what better  skirt  selectivity  (for  a  given  physical  size)  but  at  a  considerable  increase  in  cost  and,  to  change 
the  passband,  complete  additional  filters  must  be  added.  Thus,  at  the  present  date,  it  seems  that  the 
electrical  system  is  way  out  ahead  from  the  important  cost  point. 

O-  .  .  ,  ,     Fr 

''i  HE  well-known  bandwidth  loimula  B\\  =  ^  clearly  shows  that  when  Q  can  be  maintained  the  elec- 
trical systems  are  primarily  for  low  frequencies,  25  to  200  kc.  At  these  frequencies  a  mechanical  filter 
becomes  quite  large.  For  example  —  some  50  kc.  filters  that  we  made  were  }-^"  x  }^"  x  14".  At  higher 
frequencies  the  physical  size  of  mechanical  resonating  elements  becomes  so  minute  that  production 
problems  become  insurmountable.  Thus,  mechanical  filters  employing  elements  other  than  quartz  are 
practical  at  present  only  in  the  frequency  spectrum  from  about  250  to  700  kc. 

i'fjR  the  higher  frequencies  we  have  only  one  alternate  to  consider,  and  that  is  mechanical  filters  em- 
ploying the  piezo  electric  effect.  Of  all  the  materials  exhibiting  this  effect  only  quartz  has  the  necessarv 
physical  properties,  permitting  the  fabrication  of  thin,  small  elements  which  can  be  combined  into  a 
filter  network.  The  upper  frequency  limit  of  quartz  filters  is  quite  high  and  may  reach  as  much  as 
15  to  20  Mc. 

1  HE  fabrication  of  quartz  crystals  has  progressed  amazingly  since  1940  and,  likewise,  the  scientific 
knowledge  of  the  application  of  quartz  elements  in  bandpass  networks.  It  seems  logical,  therefore,  that 
further  research  may  soon  find  methods  of  obtaining  adjustable  passbands  with  one  crystal  network, 
thus  affording  a  very  versatile  new  device  for  the  design  engineer.

THE  HQ'MO-X 


•  •• 


KEEPS  NOISE  OUT! 
KEEPS  SIGNALS  IN! 


The  noise  limiter  on  the  HQ-140-X  com- 
munications receiver  really  works.  It 
keeps  noise  down  to  a  low  level  enabling 
you  to  pick  up  extremely  weak  signals. 
That's  why  the  HQ-140-X  is  rated  tops 
by  the  hundreds  of  hams  who  use  it  for 
difficult  DX  work. 

Low  noise  level  is  just  another  of  many 
reasons  why  Hams  prefer  the  HQ-140-X. 
It's  the  amateur  receiver  built  to  profes- 
sional standards.  These  professional 
standards  include  those  little  extras  in 
design,  circuitry  and  construction  not 
normally  found  in  an  amateur  receiver. 

The  extras  show  up  in  performance. 
In  addition  to  a  low  noise  level,  the 
HQ-140-X  receiver  gives  you:

for  March  of  the  KYN  (Kentucky  C.W.  Net)  shows  these 
figures:  75  sessions;  traffic  total  310,  with  an  average  of  4.01 
per  session;  48  active  stations.  ZDA  and  ZDB  make  up  an 
OM-XYL  team  on  the  KYN  as  both  are  NCS.  BAZ  is 
working  on  plans  to  get  Kentucky's  first  RACES  net  started 
with  civil  defense  in  Frankfort.  JUI  has  been  working  20- 
meter  DX  lately.  WNH  is  mobile  on  80,  40,  20,  15,  and  10

MICHIGAN  — SCM,  Thomas  G.  MitcheU,  W8RAE — 
Asst.  SCMs:  Bob  Cooper,  8AQA  ('phone);  Joe  Beljan, 
8SCW  (c.w.).  SEC:  GJH.  New  appointees  are  AIJ  as  OPS 
and  HFA  as  OES.  Congrats  to  both.  The  AUegan  V.H.F. 
Picnic  date  has  been  changed  to  Aug.  14th.  Fewer  stations 
reported  traffic  this  month,  but  our  total  is  about  the  same 
as  for  March.  The  biggest  news  for  this  report  is  that  the 
Michigan  ComPlan  for  RACES  has  just  been  approved  by 
the  FCC  and  FCDA.  This  plan  has  been  in  the  works  for 
five  years  and  represents  the  efforts  of  our  SEC  and  his 
associates  over  that  period.  Our  thanks  to  them  for  the  work 
to  date,  but  the  job  of  forming  a  working  RACES  organiza- 
tion requires  the  support  of  stations  in  this  section.  To  all 
who  have  been  waiting  and  wondering  what  we  in  Michigan 
are  doing  about  our  role  in  c.d.,  here  is  your  chance  to  offer 
your  services  and  become  RACES  Ucensed  stations.  Re- 
member, in  the  event  of  an  emergency,  only  RACES  li- 
censed stations  will  be  allowed  to  operate.  Register  via 
AREC  registration  forms,  which  are  available  from  this 
office  or  from  any  EC.  As  yet,  the  ComPlan  has  not  been 
coordinated  with  the  Michigan  Office  of  Civil  Defense 
(MOCD),  but  this  work  is  in  process  and  printed  copies 
will  be  circulated  through  the  AREC  organization  to  all 
concerned.  TBP  and  TIC  both  report  EC  activity  contin- 
uing in  the  Muskegon  Area.  FX,  still  waging  war  on  demon 
line  noise,  is  longing  for  a  rural  QTH  like  HKT's.  lUJ  is 
back  after  his  operation,  as  his  traffic  total  indicates.  AQA 
is  the  new  vice-chairman  of  his  AIEE  section  and  is  very 
QRL.  PHM  is  going  into  MARS  work  and  PHA  regrets 
that  he  can't  use  his  MARS  traffic  totals  on  the  Form  1 
reports.  WXO  has  been  QRT  overhauling  the  rig  and  re- 
building the  antenna  that  "went  with  the  wind."  NUL's 
new  buffer  stage  puts  him  up  in  the  35-watt  class  and  PDF

TJD,  vice-pres.;  CRS,  secy.;  and  HUX,  treas.  On  April 
17th  the  Toledo  Mobile  group  conducted  a  successful  scrap

HPP  as  having  a  romantic  interest.  This  was  a  tremendous 
understatement  as  she  has  been  elected  queen  and  sweet-

the  Eimac 

4X250B 

Radial-beam  power  tetrode 

•  Higher  Power 

•  Easier  Cooling 

•  Longer  Life 


ACTUAL  SIZE 


4X250B/  a  new,  superior  radial-beam  power 
tetrode  by  Eimac  —  originators  of  the  famous 
4X150A— is  now  available.  Unilaterally  inter- 
changeable with  the  4X1 50A  in  practically  all 
applications,  this  amazing  new  bantam  for  mod- 
ulator, oscillator  and  amplifier  application  from 
low  frequencies  into  UHF,  offers  these  advantages: 

HIGHER  POWER— Electrical  advances  permit  on 
increased  plate  dissipation  rating  of  250  watts, 
plate  voltages  to  2000  volts  and  doubled  plate 
power  input  capabilities  of  500  watts. 

EASIER  COOLING— Development  of  the  Eimac 
integral-finned  anode  makes  cooling  so  easy 
that  only  one-third  the  air-pressure  and  one- 
half  the  cubic  feet  of  air  ore  required.  Forced 
air  is  unnecessary  during  standby  periods. 

LONGER  LIFE— A  newly  designed,  highly  effi- 
cient oxide  cathode  and  increased  temperature 
tolerances,  coupled  with  Eimac-developed  produc- 
tion and  testing  techniques  enable  the  4X250B 
to    meet    the    most    critical    standards.   New   lech-

MALLORY  HAM  BULLETIN 


To  solve  switch  problems  around  the 
ham  shack  ...in  portable  test  equip- 
ment ...in  Civilian  Defense  gear . .  . 

USE  MALLORY  SERIES  3100-3200  ROTARY  SELECTOR  SWITCHES 

It  is  probable  that  most  amateurs  are  familiar  with  the  operation  of  Mallory  3100-3200 
series  rotary  selector  switches  when  used  in  antenna  changeover  circuits  of  the  type 
commonly  employed  in  converters,  signal  boosters,  and  RF  pre-aniphfiers  However, 
it  is  doubtful  that  very  many  amateurs  are  fully  aware  of  the  extent  to  which  these 
compact  switches  can  be  used  around  the  ham  shack  to  solve  other  switching  problems. 
In  many  respects,  the  Mallory  3100-3200  series  switches  offer  more  genuinely  useful 
features  to  the  amateur  designer  than  any  other  switch,  or  family  of  switches,  made. 
They  are  small  and  compact,  which  means  they  can  be  extremely  useful  in 
portable  test  equipment  or  Civilian  Defense  gear.  Their  axially  positioned  solder  lugs 
reduce  the  over-all  panel  space  required  for  mounting,  and  at  the  same  tune  permit 
more  convenient  wiring. 

In  spite  of  their  small  size,  the  Mallory  3100-3200  switches  do  not  sacrifice  efficiency 
or  reliability  of  operation.  Each  terminal-contact  is  fabricated  from  a  single  piece  ot 
metal  to  reduce  circuit  loss  and  the  possibility  of  intermittents.  At  6  volts  DC,  these 
contacts  will  carry  10  amperes  of  current  without  excessive  heating.  At  ^50  volts  UL., 
50  milliamperes  may  be  made  and  broken  continuously  without  harm  to  the  switch. 
Triple  X  grade  phenolic  insulation,  used  throughout,  assures  excellent  high  frequency 
operating  characteristics  for  coil  and  crystal  switching  in  either  transmitters  or  receivers. 
The  unique  Mallory  3100-3200  switch  design  has  been  field-tested  thousands  of  times 
as  an  important  component  in  expensive  commercial  test  equipment.  Research  labo- 
ratories use  it  daily  as  a  part  of  precision  measuring  devices.  And  it  is  recommended 
consistently  time  after  time  in  published  plans  detailing  the  construction  of  ordinary 
and  highly  specialized  electronic  apparatus.

in  either  shorting  or  non-shorting  styles.  Switches  of  12  positions  or  less  (30  indexing) 
are  IM"  in  diameter;  all  others  are  l^e"  in  diameter,  have  up  to  17  positions  depending 
upon  the  number  of  circuits,  and  feature  an  adjustable  stop  mechanism  Bushings  are 
standard  Vs"  in  diameter  and  have  a  #32  thread.  Shafts  are  M'  x  2  ,  and  are  pre- 
grooved  at  popular  lengths  to  permit  accurate  cutting.  An  attractive  molded  knob  is 
supplied  with  every  switch. 

Why  not  visit  your  Mallory  Distributor  today,  and  see  these  useful  switches  first  hand?

WITH  THREE  OUTSTANDING 
NEW  ITEMS  JUST  ADDED: 

ORIGINAL  VARIABLE  SINGLE  UNIT 
COIL  WITH   NEW  "DUAL  CONTACT" 

For  75-40-20-15-1 1  and  10  METER  BANDS. 
NOW  IN  THE  1955  DESIGN  with  the  NEW, 
IMPROVED  "DUAL  CONTACT"  between  the 
coil  windings  to  provide  a  greater,  more  posi- 
tive, more  efficient  contact.  Coil  can  be 
INSTANTLY  TUNED  to  ANY  DESIRED  BAND 
or  FREQUENCY  by  ingenious  locking  device. 
Factory  pretuned.  Continuous  coverage  from 
3750  kcs.  to  30,000  kcs.  Highest  "Q"  avail- 
able in  an  ail-band  coil.  Fits  all  whips  and  bases.

VAARO— THE  ORIGINAL 
"WHIP  FLEXOR" 

Since  75  meters  and 
other  low  frequencies 
began,  a  new  prob- 
lem has  arisen.  Any 
change  of  antenna  :: -: t;.; 
(voltage  portion)  in 
relation  to  car  body, 
changes  loading  and 
therefore  changes 
output  tremendously. 
This  problem  has  been  overcome  by  the 
"WHIP  FLEXOR"  which  serves  a  dual  purpose 
...  It  is  designed  to  keep  the  whip  perpendicu- 
lar at  extremely  high  speeds  while  allowing 
the  whip  to  be  brought  down  in  a  horizontal 
plane  for  garage  storage,  etc.  This  elimination 
of  a  base  section  spring  prevents  bad  "QSB" 
action  on  the  receiver  end.  .  .  .

P^DJ  deserves  great  credit  for  the  way  he  has  been  sparking 
the  ORC  for  the  past  two  years.  YDI  is  one  of  the  most 
faithful  reporters  among  the  OPS  gang.  Unfortunately 
Bland  does  not  get  much  traffic  over  the  Mission  Trail 
for  Martinez.  One  of  the  newest  hams  to  liave  an  official

READ  THIS  AMAZING  LETTER:  How  an  inexpensive  riiu. 
SIZE  Gotliam  Rotary  Beam  made  it  possible  to  "worit  the  world!" 


Florida,  13  May  1955 

Gentlemen: 

I'd  like  to  express  my  enthusiasm  and  satisfaction 
regarding  your  20-meter  rotary  beam  antenna.  1  pur- 
chased one  of  your  standard  two-element  units  in 
February  of  this  year.  Prior  to  this  time  I  had  been 
using  a  collinear  array  about  one  wavelength  above 
ground.  The  transmitter  feeding  this  antenna  had  a 
power  output  of  about  35  watts,  and  results  were  (juite 
discouraging. 

When  my  Gotham  arrived,  it  was  easily  assembled 
in  a  couple  hours.  The  same  transmitter  was  used  to 
excite  the  Gotham  antenna,  using  the  same  power  as 
before.  Results  have  been  quite  gratifving,  and  it  is 
interesting  to  note  that  in  the  three  months  since  using 
the  Gotham  anteaaa,  I  have  worked  87  foreign  coun- 
tries, all  continents,  and  40  zones.

I  am  able  to  keep  schedule  with  amateur  radio * 

in  the  Cape  Verde  Islands  cn  ery  week.  It  was  impos- 
sible to  even  hear  this  station  bejore  using  the  Colhant 
beam. 

Extremely  high  winds  are  i>revalcnt  in  this  part 
of  Florida.  The  (jotham  beam  has  withstood  blows 
in  excess  of  50  miles  an  hour  without  failure. 

I  have  enthusiastically  rectimmcnded  Gotham 
to  all  the  liains  who  ask  what  type  I  am  using  (and 
most  of  them  do,  when  1  tell  them  the  amount  of 
power  I'm  using).  I  wish  you  every  success  with  your 
product,  and  feel  that  it  is  well  worth  the  modest  price. 

(name  and  call  letters 
upon  request)* 


EVERY   FULL-SIZE   GOTHAM    ROTARY    BEAM   IS  ENGINEERED  FOR    SIMPLICITY,   STRENGTH,    PERFORMANCE 

Your  Gothom   comes  to  you  completely   fabricoted,   made  good,  solid  tubing  and  not  flimsy  wire.  Easy  assembly,  simple 

(except  for  the  polystyrene  insulator)  entirely  of  new,  rust-  and  quick  matching  of  line  to  antenna.  Yet  Gotham's  price 

less,   first-qualily    mill    stock    aluminum.    You'll    find    no    link  is  25%  to  75%  lower  than  the  midget  beams  which  Gotham 

coupling,  no  complicated   mounts,  no  tuning  stubs.  You  get  so  easily  out-performs.

If  disaster  should  strike,  will  your  com-

time  of  disaster,  there  is  no  substitute 
for  dependability  —  even  initial  cost

words in  the  final  selection  of  these

The  AMPEREX  6252  ICAS  higher  voltage  and  input  ratings  show  the 
advantage  of  the  independently  suspended  anode  construction 
which  eliminates  the  need  for  internal  insulation.  Competitive  tubes 
use  mica  insulators  between  the  plate  and  the  rest  of  the  internal 
structure,  resulting  in  low  maximum  anode  voltage  and  greater 
derating  at  higher  frequencies.

VE7.JT  —  SEC:  DH.  Summer  being  well  on  the  way  every- 
body will  be  doing  all  the  usual  summer  antenna  repairs, 
and  dodging  the  ever-present  household  chores.  Barring  the 
few  traffic  reports  this  month  there  is  not  much  to  report. 
The  mobile  activity  is  picking  up  now  that  the  good  weather 
is  here  with  hidden  transmitter  hunts  and  mobile  picni  s 
in  the  offing.  The  last  hidden  transmitter  hunt  of  May  1st 
was  taped  and  should  have  been  heard  on  the  CBC  Roving 
Reporter  series  on  the  local  Vancouver  CBC  station,  CBU. 
Last  month's  column,  I  hope,  will  bring  some  things  to  re- 
port next  month.  Keep  your  ears  open  for  7JB,  whose  aim 
has  been  to  start  a  swap  and  shop  gimmick  for  the  amateurs 
at  a  convenient  location.  It  should  prove  very  beneficial 
for  the  amateurs  to  trade  or  swap  for  the  stuff  they  need 
with  what  they  have  that  someone  else  wants.  Also  every 
Wed.  night  on  the  AREC  Net  on  3755  kc.  is  the  swap 
column  night.  There  is  a  list  of  phonetirs  printed  in  the 
Handbook.  It  would  save  a  lot  of  the  net's  time  if  the  stations 
would  use  phonetics,  especially  when  making  relays.  Give 
it  a  try!  Traffic:  VE7QC  208,  ASR  105,  AQW  44,  AUF  32,

SASKATCHEWAN  — SCM,  Harold  R.  Horn,  VE5HR 
—  This  report  is  being  made  up  at  the  hospital,  my  QTH 
for  the  past  two  months.  I  would  like  to  say  thanks  to  all  the 
gang  for  the  kind  wishes  that  have  been  received,  both  via 
75  meters  and  by  card.  Through  the  courtesy  of  TH  I  have 
an  S-38  and  it  has  given  me  many  pleasant  hours  listening 
in  on  the  bands.  BD  is  on  28-Mc.  mobile  'phone.  BZ  is  going 
to  14  Mc.  for  the  summer.  FG  is  QSY  Moose  Jaw.  When  two 
local  public  schools  held  Hobby  Shows,  BG  and  HR  set 
their  stations  up.  A  number  of  contacts  were  made  and  the 
display  was  well  received  by  the  public  as  well  as  the  school 
children.  JO  has  been  promoted  with  the  Power  Corporation 
and  is  now  located  at  Regina  Beach.  We  regret  to  record  the 
passing  of  SD  on  Apr.  13th.  He  will  be  greatly  missed  by 
the  Prince  Albert  Club.  DR  made  BPL  with  his  traffic 
handled  during  the  big  blow.  5AJ  and  GAL  were  instru- 
mental in  locating  an  overdue  aircraft  en  route  to  Saskatoon 
during  the  big  storm.  Traffic:  VE5DR  177,  YF  33,  RE  2G.

hold  the  loop  thus  formed.  The  tap  should  l)e 
tinned  before  the  coil  is  mounted,  to  faeiiitate 
connecting  the  lead  from  (\.  L5  is  wound  in  a 
straightforward  manner,  terminating  on  the 
split-ring  terminals  provided  with  the  LS-3  coil 
form.  Cio  is  connected  across  the  coil  to  these 
same  rings.  After  winding,  both  coils  should  be 
coated  with  coil  "dope."  Li,  L3,  and  L4  are  pre- 
wound  coils  and  can  be  adjusted  to  resonate  to 
the  required  frequencies  with  tube  and  circuit 
capacitances. 

Most  wiring  can  l)e  completed  point  to  point, 
except  the  B-plus,  which  is  terminated  on  tie 
points.  In  the  Central  Electronics  e.xciter  the  6.3- 
volt  filament  supply  has  its  center  tap  grounded, 
necessitating  a  two-wire  filament  circuit.  The 
wiring  to  the  oscillator  section  was  run  in  the 
fold  of  the  chassis  and  didn't  have  to  go  through 
the  shield  since  there  was  sufficient  room  for 
these  leads  between  the  shield  and  the  chassis. 
However,  the  wires  could  be  fed  through  a  34- 
inch  rubber  grommet  if  necessary. 

The  interconnecting  cable  is  made  up  of  3 
ordinary  leads  and  a  piece  of  coax  for  the  r.f. 
The  plugs  on  each  end,  and  their  connections, 
will  be  determined  by  the  type  of  socket  on  the 
exciter  (octal  on  the  10-A)  and  Ji.  The  cable  was 
taped  with  Scotch  electrical  tape  for  neatness. 

Adjustment 

First,  check  all  wiring  and  determine  that  no 
errors  exist.  Then  connect  the  cable  between  the 
exciter  and  the  VFO.  Turn  on  the  exciter  and 
determine  that  both  tube  filaments  light.  Do 
this  with  the  VR  tube  out  of  its  socket  as  the 
jumper  in  the  tube  will  open  the  B-plus  to  the 
tubes.  Remove  both  tubes  from  their  sockets, 
replace  the  0B2  and  adjust  the  dropping  resistor 
for  23  to  25  ma.  of  current  through  the  VR  tul)e. 
Next,  insert  the  oscillator  tube,  Fi,  and  listen 
around  5  Mc.  in  the  receiver  for  the  oscillation. 
It  would  be  wise  to  connect  a  low-range  milliam- 
meter  between  the  cathode  choke  and  ground. 
It  should  indicate  approximately  10  ma.  Peak 
the  signal  with  the  slug  in  L<i. 

Now  comes  the  important  part,  to  determine 
the  range  of  the  oscillator  from  maximum  to 
minimum  capacity.  It  will  be  more  than  the  re- 
quired 500  kc.  Set  the  5-Mc.  point  at  5  on  the 
logging  scale,  by  adjusting  the  slug  in  L\.  Now 
carefully  remove  one  plate  at  a  time  from  Ci, 
readjusting  L\  as  necessary.  As  each  plate  is  re- 
moved, record  the  new  range  of  the  os:'ilIator  on 
a  piece  of  paper.  As  you  progress,  a  pattern  will 
emerge  of  the  ratio  of  change  as  each  plate  is 
removed.  When  the  500-kc.  range  occupies  almost 
all  of  the  scale,  the  pattern  will  warn  you  that 
to  take  off  one  plate  more  will  be  one  too  many. 
This  procedure  determines  the  l)andspread  of 
the  VFO.  Th(>  writer's  VFO  covers  the  500  kc. 
nec>ded  between  5  and  S)3  on  th(>  logging  scale 
of  the  MCN  dial. 

Next,  plug  in  the  buffer/multi[)lier  tulie,  set

Air-System 
Sockets 


LllTldC  air-system  sockets  are  custom  designed  to  provide 
adequate  cooling  witli  the  most  economical  blower  requirements 
for  several  Eimac  radial-beam  power  tetrodes. 

4-400A/4000  air-system  socket  is  employed  with  Eimac  tube 
type  4-400A,  Air  enters  through  the  bottom  of  the  socket  and  is 
guided  by  a  pyrex  glass  chimney,  assuring  efficient  cooling  of 
the  various  seals.  If  desired,  this  socket  may  also  be  used  with 
Eimac  4-125A  and  4-250A. 

4-1000A/4000  air-system  socket  is  designed  for  use  with  Eimac 
tube  type  4-IOOOA.  Air  entering  the  bottom  of  the  socket  is 
guided  by  a  pyrex  glass  chimney  toward  the  plate  seal,  assuring 
correct  cooling  even  during  maximum  rating  operation  of  the 
tube. 

4X150A/'4000  air-system  socket  provides  adequate  air  cooling 
and  high  frequency  circuit  arrangement  for  Eimac  4X150A  and 
4X150D.  Air  enters  the  socket  through  the  bottom  and  is  guided 
by  a  ceramic  chimney. 

4X150A/4010  socket  Is  identical  to  the  4X150A,  4000  except  that 
this  socket  is  complete  with  grounded  cathode  connecting  tabs. 

Eimac  air-system  sockets  and  chimneys  are  also  available  as 
separate  units.

end.  Next,  set  the  dial  near  the  5.4-Mc.  point 
and  the  bandswitch  to  the  40-meter  position, 
and  look  for  the  signal  around  16.2  Mc.  on  the 
receiver.  Now  peak  L5.  For  accurate  placement 
of  the  5.0-Mc.  point  (about  5  on  the  logging 
scale)  zero-beat  the  oscillator  with  th'>  5-Mc. 
signal  of  WWV  and  adjust  the  slug  in  Li.  This 
comjjletes  the  adjustment,  but  after  attaching 
the  cover  (bottom  plate)  with  sheet  metal  s:>rews, 
recheck  all  the  above  adjustments,  touching  up 
the  slugs  where  needed. 

The  oscillator  adjustment  procedure  can  also 
be  used  to  adjust  the  handset  dial  on  two-dial 
receivers.  With  the  10-A  in  "Cal,"  set  the  band- 
spread  dial  on  the  receiver  to  4.0  Mc,  then  care- 
fully tune  the  handset  dial  until  the  signal  is 
heard  zero  beat.  The  receiver  is  then  calibrated 
for  the  75-meter  band  at  4.0  Mc.  (provided  the 
9-Mc.  crystal  in  the  exciter  actually  is  on  ex- 
actly 9  Mc). 

Your  VFO  is  now  ready  to  give  j^ou  s.s.b. 
operation  on  four  bands.

Break-In  Keying 

{Continued  from  page  SS) 

If  the  action  just  described  is  not  obtained, 
you  probably  have  the  rectifiers  connected  back- 
wards, and  they  should  be  reversed.  It  should  be 
apparent,  of  course,  that  the  same  principle  can 
be  applied  to  a  transmitter  currently  using  grid- 
block  keying,  since  the  pertinent  parts  of  the 
kej^ed  circuit  are  similar.  A  vacuum  tube  diode 
can  be  used  in  place  of  the  selenium  rectifier,  but  it 
must  be  shunted  by  a  high  resistance  to  simulate 
the  back  resistance. 

I  have  been  using  this  system  for  two  years 
and  have  no  reason  to  ask  for  more.  The  keying 
is  clean  because  the  characters  are  being  formed 
in  the  next  to  the  last  stage  of  the  transmitter, 
and  no  back  wave  is  heard  with  the  key  open  and 
the  receiver  set  at  above  normal  gain. 


Six  Meters 

{Continued  from  page  32) 

Such  a  coupler  or  balun  can  be  connected  any- 
where: at  the  transmitter,  at  any  convenient 
point  between  the  rig  and  antenna,  or  at  the  an- 
tenna itS3lf. 

An  antenna  system  that  is  designed  for  300- 
ohm  Twin-Lead  feed,  such  as  the  4-element  ar- 
ray described  in  all  the  Handbooks,  can  be  fed 
with  coax  and  either  of  the  coupling  devices 
shown  in  Fig.  2.  The  coupling  circuit  of  Fig.  2A 
can  be  used  with  either  50-  or  75-olim  coax,  and 
the  line  can  be  any  balanced  transmission  line 
presently  available.  The  components  of  the 
coupler  can  be  similar  to  those  used  in  the  plate 
and  output-coupling  circuits  of  the  final  stage. 

Adjustment  of  the  coupler  and  the  antenna 
system  can  be  done  positively  only  if  a  standing- 
wave  indicator  of  some  sort  is  inserted  in  the 
coaxial  line.  Adjustments  should  be  made  for 
minimum  standing-wave  ratio  first,  and  then  the 
coupling  at  the  transmitter  should  be  set  for  the 
desired  loading.  A  low  s.w.r.  is  particularly  im- 
portant if  coaxial  line  is  used  all  the  way  to  the 
antenna  system.  The  design  and  use  of  s.w.r. 
bridges  are  covered  in  all  recent  Hanibooks.

What's  the  Answer? 

(Continued  from  page  36) 

frccinency,  expressed  in  kilocj'cles  or  megacycles. 
In  the  earl}-  daj-s  of  radio,  amateur  bands  were 
listed  by  meters.  In  the  interest  of  accuracy, 
the  " povvers-that-be "  switched  to  frequency 
designations  for  the  radio  spectrum.  However, 
habits  die  hard,  and  although  the  change  was 
made  in  the  late  '20s,  it  is  still  common  practice 
to  use  meters  as  band  designations. 

If  one  wishes  to  convert  frequency-in-kilo- 
cycles  into  wavelength-in-met ers,  and  inciden- 
tally, this  is  a  question  sometimes  asked  in  the 
Novice  exam,  the  following  formula  is  used: 

300,000 


A  = 


/ 


where         A  =  Wavelength  in  meters 
/  =  Frequenc.y  in  kilocycles 

Example:  The  wavelength  corresponding  to  a 
frequency  of  3500  kilocycles  is 


A  = 


300,000 
3500 


=  85.7  meters. 


Lightning  Protection 

{Continued  from  page  37) 

antenna  was  cut  to  center  on  this  frequency. 
Operation  is  not  confined  to  this  frequencj', 
however,  as  many  contacts  are  made  even  at 
the  high  end  of  the  band  without  any  retuning 
or  adjustment  of  either  the  driver  or  final- 
stage  tuning  circuits. 

The  antenna  is  125  feet  long  and  the  quarter- 
wave  Zepp  feeders  are  623^^  feet  long,  spaced 
6  inches  apart.  The  feeders  are  tied  together  at 
the  lower  end  and  grounded.  A  metal  rod  6 
inches  long  is  used  as  the  lowest  spacer.  RG-1  l/U 
(72-ohm)  coax  is  used  to  feed  the  Zepp  feeders. 
The  shield  of  the  coax  is  attached  to  the  feeder 
which  goes  to  the  antenna  and  the  center  con- 
ductor goes  to  the  other  feeder  which  dead  ends 
at  the  antenna.  The  point  of  attachment  is  about 
24  inches  from  the  shorting  bar.  The  coax  is  tied 
to  the  feeder  to  which  the  shield  is  connected  and 
follows  it  back  to  the  shorting  bar  and  then 
follows  the  ground  lead  to  the  ground  stake  and 
from  there  runs  underground  to  the  house. 

By  now  you  are  wondering  why  the  shield  is 
connected  to  the  feeder  which  goes  to  the  antenna 
instead  of  being  attached  to  the  feeder  which 
dead  ends.  Actually,  it  makes  no  difference 
which  waj'  you  do  it,  except  that  if  you  use  a 
bridge  to  check  the  standing-wave  ratio,  j^ou 
will  have  more  trouble  with  induced  voltages 
from  local  broadcast  stations  if  you  reverse  the 
connection,  since  the  feeder  plus  antenna  picks 
up  much  more  of  this  broadcast  field  voltage 
than  the  dead-ended  feeder  alone  will  pick  up. 

Another  benefit  from  this  antenna  which  was 
entirely  unexpected  is  the  reduction  in  harmonics 
reaching  the  antenna.  At  the  desired  frequency, 
the  4  feet  of  wire  between  the  ends  of  the  coax 
and  the  shorting  bar  serve  as  a  transformer  to

STEEL  TOWERS 

For  Rotary  Beams,  FM,  TV 


You  can  erect  this  tower  yourself.  Just  dig 
four  holes,  set  anchor  posts  in  place,  bolt  the 
pieces  together.  5h  ft.  ladder  sections  make 
it  easy  to  work  higher  as  tower  goes  up.  It's 
a  lot  of  fun  to  build  your  own  tower  —  and 
saves  you  money,  too!

match  the  impedance  of  the  coax  to  the  imped- 
ance of  the  open-wire  feeders.  At  other  frequen- 
cies, however,  this  is  not  the  case,  and  the  higher- 
order  harmonics  are  effectivel}'  suppressed.  No 
other  filter  is  used  at  W4Zt!  for  this  purpose  and 
there  is  no  oi)servable  interference  on  a  television 
receiver  connected  to  an  antenna  just  15  feet 
away  from  the  Zepp  feeders. 

Should  you  wish  to  use  this  antenna  on  other 
bands,  you  may  do  so  by  reducing  the  dimen- 
sions in  accordance  with  standard  antenna 
formulas.  The  point  of  connection  of  the  coax  to 
the  Zepp  feeders  is  not  critical  and  may  vary 
somewhat  under  different  surrounding  conditions. 
It  can  best  be  done  by  measuring  the  s.w.r.  at 
the  transmitter  end  of  the  coax  at  several 
different  test  positions,  but  if  no  bridge  is 
available,  the  connection  of  the  coax  to  the 
Zepp  feeders  may  be  made  24  inches  from  the 
shorting  bar  for  80  meters,  12  inches  for  40 
meters,  6  inches  for  20  meters,  and  3  inches 
for  10  meters.^  It  is  desirable  that  the  feeder 
spacing  be  reduced  at  the  higher  frequencies 
as  the  length  of  the  shorting  bar  is  a  factor  in  the 
impedance  match.

lengths  are  the  same  as  above  in  terms  of  wavelength.  —  En.

minimizing  the  noise  figure  of  the  second  stage.  To  calculate 
the  noise  figure  of  this  combination  we  need  to  calculate  the 
noise  contributions  of  the  two  tubes,  and  if  for  simphcity 
we  assume  the  two  noise  figures  are  identical,  the  noise 
figure  of  the  combination  can  be  shown  to  differ  little  from 
that  of  the  first  circuit.  * 

If  the  tap  on  the  interstage  coupling  coil  is  left  out  this 
circuit  becomes  the  so-called  "cathode-coupled  amplifier" 
shown  below: 


R.F  AMP 


The  noise  figure  of  this  combination  is  slightly  poorer. 
Since  the  two  triodes  here  are  directly  connected  through 
their  common  cathodes,  a  valve  often  used  in  this  circuit 
is  a  Type  6J6  (whose  equivalent  noise  resistance  is  470  ohms 
for  each  triode  section).  This  circuit  is  identical  to  that  used 
by  Longerich  and  Smith,  except  that  a.c.  coupling  is  em- 
ployed rather  than  direct  coupling  and  the  series-resonated 
coil  in  the  cathode  is  replaced  by  a  resistor.  The  noise  figure 
of  the  cathode-coupled  amplifier  is  in  general  sjmewhat 
better  than  the  grounded-cathode  pentode  amplifier.  This 
circuit  is,  however,  inferior  to  the  grounded-cathode 
grounded-grid  triode  circuit  in  both  noise  figure  and  stability 
(i.e.,  the  so-called  Wallman  circuit  ^  or  cascode  r.f.  ampli- 
fier 3).  Also,  the  lower  available  power  gain  of  the  grounded- 
plate  triode  means  that  contributions  of  third-stage  noise 
are  correspondingly  greater.

Happenings 

{Continued  from  page  44) 

64)  On  motion  of  Mr.  Gowan,  VOTED  that  the  Presi- 
dent appoint  a  Membership  &  Publications  Committee 
for  the  purpose  of  reporting  to  the  Board  at  its  next  meeting 
recommendations  for  increasing  membership  and  interest 
in  ARRL  among  Novices  and  beginning  amateurs.  The 
Committee  is  requested  to  consider,  among  other  things, 
the  feasibility  of  the  establishment  of  a  "Student  Grade" 
membership  and  the  publication  of  a  Novice  Handbook. 

65)  At  this  point,  the  President  announced  the  following 
are  appointed  to  the  Membership  &  Publications  Com- 
mittee for  the  following  year:  Mr.  Maer,  Chairman,  Mr. 
Gowan  and  Mr.  Steed. 

66)  At  this  point,  without  formal  action,  the  Board  and 
its  General  Counsel,  at  the  request  of  Mr.  Cornell,  engaged 
in  an  extensive  discussion  of  Article  12  of  the  Articles  of 
Association. 

67)  On  motion  of  Mr.  Roberts,  the  following  resolution 
was  unanimously  .\DOPTED: 

WHEREAS,  Karl  W.  Weingarten,  W7BG,  had  for 
nearly  twenty  years  served  The  American  Radio  Relay 
League  and  amateur  radio  as  Director  and  Vice  Director 
of  the  Northwestern  Division,  and 

WHEREAS,  the  institution  of  amateur  radio  is  deeply 
grieved  by  his  passing  on  December  2,  1954 

Now,  therefore,  BE  IT  RESOLVED,  that  the  Board 
of  Directors  of  The  American  Radio  Relay  League, 
meeting  at  Hartford,  Connecticut  on  May  14,  1955,  on 
behalf  of  amateur  radio  hereby  expresses  its  deep  sense 
of  loss  at  his  passing. 

68)  On  motion  of  Mr.  Maer  (on  behalf  of  Mr.  Cornell), 
unanimously  VOTED  that  the  Board  of  Directors  of  the 
League  authorizes  a  National  Convention  to  be  held  in  the 
Pacific  Division  of  the  League  during  the  year  1956,  under 
terms  as  may  be  approved  by  the  Executive  Committee 
upon  receipt  of  a  satisfactory  request  from  a  responsible 
group  to  sponsor  such  a  convention. 

69)  On  motion  of  Mr.  Maer,  unanimously  VOTED, 
that  the  General  Manager  is  hereby  authorized  to  pay 
expenses  for  the  operation  of  the  Membership  &  Publica- 
tions Committee  during  the  year  1955  in  an  amount  not  to 
exceed  $1000. 

70)  Whereupon,  on  motion  of  Mr.  Schmidt,  the  Board 
adjourned  sine  die  at  10:46  a.m. 

71)  (Time  in  session  as  a  Board,  9  hours,  54  minutes; 
total  authorizations  $28,150.)

ingiy  working  right  below.  Once  I  almost  had  the 
best  beam  of  anybody  in  the  graveyard. 

4)  Lay  the  ladder  down  gently,  Stupid.  Don't 
bounce  it  off  your  big  toe  as  I  always  do. 

5)  Don't  service  an  antenna,  accompanied  by 
8000  angry  bees,  without  wearing  the  baby's  crib 
netting  over  your  head.  Caution:  Tuck  it  in.  Second 
caution:  If  you  have  a  big  nose  forget  the  whole 
beezness. 

Measuremen  ts 

1)  The  arc  off  the  final  "test."  A  certain  Long 
Island  W2,  who  should  have  known  better,  popped 
a  pretty  good  bottle  that  way.  Now  he's  QRP. 

2)  The  "voltage  measurement  test,"  also  known 
as  the  "grabbed  it"  test.  Not  accurate,  but  rather 
shocking.  LTse  your  own  calibration  system. 

3)  The  "wonder  if  it's  turned  on"  test.  You  too? 

4)  The  "whoops,  shorted  it"  test. 

5)  The  "burned  finger"  test.  Quite  handy  in 
finding  out  which  tube  is  cold.  It's  always  the  last 

one.

Frustration  in  General 

1)  Never  live  on  the  East  Coast.  You  get  all  the 
blackouts  and  magnetic  storms.  When  it  gets  so 
bad  back  East  that  you  can't  even  give  your  neighbor 
his  accustomed  TVI,  the  West  Coast  goes  merrily 
on  it's  happy  DXing  way.  (Known  as  East  Coast 
ulcers.) 

2)  Even  though  the  postman  is  the  ham's  best 
friend,  the  inflated  foreign  postal  rates  will  really 
get  you.  It's  no  longer  "Will  you  send  me  a  card?" 
but  "Can  you  afford  it?".  Just  one  more  hazard  on 
top  of  "Sorry  you  ain't  in  my  log,"  wrong  call  on 
QSL  card,  essential  contact  info  missing,  etc. 

3)  Incidentally,  once  the  other  guy  gets  your  call 
wrong,  you  can  do  a  jig,  stand  on  your  head,  etc., 
while  he  says  "solid  copy  R  R  wrong  call  R  R." 
Why  not  a  Q  signal  for  "Listen  carefully,  dumbbell, 
my  call  is "  ?  Do  you  go  off  talking  to  your- 
self, too? 

4)  Never,  never,  never  put  up  a  brand-new  3-ele- 
ment  beam  just  ahead  of  those  three  witches  — 
Carol,  Edna  and  Hazel.  We  ain't  had  a  hurricane 
around  here  for  nigh  onto  10  years.  So  GVZ  be- 
latedly goes  modern  again.  (This  is  one  case  where 
outdoor  plumbing  is  best.)  And  what  happens? 
Bam,  zowie,  whee  —  Hellion  Hazel  turned  my  hair 
black  again,  what  with  watching  what  looked  like 
my  beam's  death  agonies.  My  hair  even  stood  up 
on  end,  quite  a  trick  considering  that  the  baldies 
wore  it  all  off  years  ago.  Just  when  I  was  mentally 
framing  an  epitaph  which  said  "Born  in  June, 
died  in  October,"  Hazel  went  away  and  bothered 
someone  else.  A  big  apple  tree  fell  on  the  house,  we 
had  no  power  for  three  days,  the  food  in  the  freezer 
went  defunct,  but  who  cared?  The  beam  survived 
undamaged! 

Guess  I  don't  need  that  new  book  after  all. 
For  once  I  must  have  done  it  right!!! 


W4EUV  wonders  if  there  is  any  paint  or  coat- 
ing that  would  keep  woodpeckers  from  slowly 
disintegrating  his  beam  pole! 

K6BF,  B.  J.  Kroger  of  Santa  Barbara,  Calif., 
who  has  kept  a  100  per  cent  log  for  over  thirty 
years,  recently  had  his  20,000th  QSO  on  2  meters 
with  K6HEC,  Oxnard.  Kroger  has  had  11  calls  in 
four  U  S.  districts,  Nicaragua  and  Mexico.

open  end,  with  coupling  loops  for  injection  and  input.  The 
line  is  tapped  for  a  crystal-diode  mixer.  Item  4  is  a  wave- 
meter  tuning  from  300  to  1300  Mc,  by  W6RJS.  Near  it  is 
a  1296-Mc.  tripler  (5)  similar  to  one  soon  to  appear  in  QST. 
It  was  built  by  W6DQJ,  and  it  uses  a  2C39A  tube,  which 
may  be  seen  on  the  floor  in  front  of  it. 

A  converter  for  1215  Mc.  shown  at  (6)  uses  the  r.f.  as- 
sembly from  an  AN/TRC-5.  It  has  two  resonant  circuits 
preceding  the  crystal  mixer.  Its  local  oscillator  uses  a  2C40. 
One  stage  of  30-Mc.  i.f.  amplification  is  included.  It  is  the 
property  of  W6DQJ.  The  APS-13  (7)  is  useful  as  an  i.f. 
system  for  u.h.f.  or  microwave  work.  W6DQJ  uses  its 
30-Mc.  i.f.  with  the  converter  described  above. 

In  his  other  hand  Don  holds  a  complete  transmitter  and 
receiver  for  1215  Mc.  A  local  oscillator  from  a  TPS-1  serves 
as  a  transmitter,  its  type  446A  tube  delivering  about  J^ 
watt.  The  receiver  section  has  another  446  local  oscillator 
feeding  a  crystal  mixer.  A  cascode  i.f.  stage  on  30  Mc.  is 
link  coupled  to  a  TV  i.f.  strip  modified  for  6AK5  tubes.  A 
single  audio  section  is  used  for  both  receiver  output  and 
Heising  modulator.  The  power  supply  for  this  station  is 
shown  between  items  (3)  and  (5). 

At  the  right  of  the  photograph  is  an  APT-5,  property  of 
W6RJS.  This  jammer,  a  common  item  in  the  heyday  of 
low-priced  surplus  gear,  has  a  relatively  high-powered 
oscillator  tuning  from  about  300  to  above  1200  Mc. 

Demonstration  of  the  gear  included  two-way  communica- 
tion by  W6CFL  and  W6MMU,  and  considerable  interest 
was  generated  that  should  provide  company  for  W6CFL, 
W6DQJ,  and  W6NLZ,  u.h.f.  pioneers  of  the  Los  Angeles 
area. 

OES  Notes 

K2GAN,  Murray  Hill,  N.  J.  —  Constructed  chassis  with 
5  different  overtone  oscillator  circuits,  to  permit  compari- 
sons that  will  determine  their  respective  merits  for  use  in 
2-meter  transmitters  and  converters.  Also  experimenting 
with  crystal  grinding. 

K2DYC,  Phelps,  N.  K.  —  50-Mc.  transmitter  similar  to 
October,  1954,  QST,  about  completed. 

WWRA,  Collingswood,  N.  J.  —Activity  on  50  Mc.  pick- 
ing up  steadily  in  the  Philadelphia-to-Washington  area, 
but  little  heard  from  the  north.  Will  cooperate  with  inter- 
ested 50-Mc.  operators  in  early-morning  schedules,  begin- 
ning at  6:30  EDST.  Should  be  attractive  to  those  who  are 
kept  from  operating  in  evening  hours  because  of  the  threat 
of  Channel  2  TVI. 

Recently  put  in  50-Mc.  crystal.  This  may  be  TVI  solu- 
tion for  some  who  think  Channel  2  TVI  is  impossible  to 
correct.  Much  trouble  may  come  from  unwanted  harmonics 
of  6-  or  8-Mc.  crystals  falling  in  Channel  2,  rather  than 
from  blocking  by  the  50-Mc.  fundamental. 

W2UXP,  Webster,  N.  Y.  —  Several  new  stations  ex- 
pected soon  on  50  and  220  Mc. 

W3PMG,  Chinchilla,  Pa.  —  Small  transmitter-receiver 
set-ups  for  50,  144,  220  and  420  Mc.  under  construction  for 
use  by  W3KX/3  in  V.H.F.  Party  and  Field  Day. 

WSUQJ,  York,  Pa.  —  New  2E26  rig  running  on  50.3 
Mc.  with  3-element  array.  Will  soon  have  829-B  final. 
Skeds  being  run  with  W30TC,  Silver  Spring,  Md.,  on  6. 
Activity  growing  on  50  Mc,  new  stations  including  W3s 
OWW  OCI  ALN  AXC  and  SST. 

W4HHK,  Collierville,  Tenn.  —  Monitoring  50.1  Mc. 
daily  with  fix-tuned  receiver.  Six-meter  rig  with  p.p. 
6146s  under  construction.  Also  planning  220-Mc.  exciter  for 
4X150  220-420  final  already  on  hand.  Double  conversion 
with  single  crystal  planned  for  432-Mc.  reception.  Crystal 
on  42.5  Mc.  is  to  be  multiplied  9  times  for  injection  at 
382.5  Mc,  converting  the  432-436-Mc.  range  to  39.5  to 
53.5  Mc.  The  42.5-Mc.  signal  also  beats  with  the  latter 
range  in  a  second  mixer  to  produce  an  i.f.  of  7  to  1 1  Mc.  to 
be  tuned  on  the  HRO. 

W4IKK,  Rome,  Ga.  —  Experimenting  with  50-Mc. 
phase  modulation,  in  attempt  to  reduce  TVI  in  fringe-area 
reception  of  Channel  2  from  Atlanta.  Most  of  the  TVI  was 
of  an  audio  nature  with  the  a.m.  rig,  picture  being  unaf- 
fected except  in  immediate  vicinity.  Working  W4AKX, 
Gadsden,  Ala.,  on  Six,  .55  miles. 

W4UIW,  Miami,  Fla.  —  Active  stations  on  144  Mc. 
include  W4s  RNV  KQG  UIW  FLH  and  JZB,  with  more 
activity  coming.  [See  report  of  reception  of  Miami  area

W7TMU,  Snohomish,  Wash.  —  New  activity  developing 
on  50  Mc.  since  appearance  of  Technicians,  April  12th. 
Now  have  11  stations  using  the  band  locally,  with  more  to 
come.  Activity  on  144  Mc.  dropped,  it  is  hoped  temporarily, 
as  a  result  of  polarization  controversy. 

W7UKI,  Marysville,  Wash.  —  Experimenting  with 
1N34  crystal  mixer,  heard  W7TMU,  15  miles  away,  while 
using  only  indoor  folded  dipole.  Believe  it  would  make  a 
satisfactory  converter  if  used  %vith  good  r.f.  amplifier  and 
crystal-con troUed  injection. 

W7YJE,  Seattle,  TTos;*.  —  First  good  50-Mc.  opening  of 
the  season.  May  14th.  W7s  PRW  UFE  and  DYD  worked 
around  10  stations  each  in  Southern  California.  Local 
6-meter  gang  check  band  nightly  at  1900  PST. 

W8HCD,  Dayton,  0/iio  —  Six-meter  band  used  locally 
principally  for  contests.  Activity  otherwise  is  low  because 
of  Channel  2  trouble.  Have  been  able  to  put  out  up  to  10 
watts  without  TVI,  using  either  c.w.  or  f.m.  Amplitude 
modulation  increases  TVI  potential  greatly. 

New  32-element  144-Mc.  array  at  50  feet  above  ground

—  another  multiplier  —  I  couldn't  give  up  W9CXY. 
An  hour  later  the  burning  odor  persisted.  Not  my 
transmitter,  I  happily  thought.  Then  —  oh  no  — 
our  dinner!  Must  save  it  and  our  once  happy  home. 
Wonder  if  I  can  keep  the  rig  when  our  divorce  is 
final?  Our  dinner  looked  and  tasted  like  a  prehis- 
toric man  dug  from  the  peat  bogs.  There  was  no 
conversation. 

But  I  wouldn't  have  missed  it  —  not  even  for  a 
kilowatt  with  a  charmed  maintenance  life  and  proper 
voltages  on  the  oscillator.  Take  it  from  a  seven  year 
'phone  gal,  c.w.  is  here  to  stay  and  contests  are  a  very 
pleasant  form  of  mayhem.

Net  picnic  in  May  at  Columbus,  Ohio.  .  .  .  W4BLR,  Kay, 
made  BPL  for  April.  .  .  .  WSNNH's  contacts  with  EA8BF, 
Canary  Islands  and  GD3IBL,  Isle  of  Man,  have  spurred 
her  on  to  more  DX  hunting.  .  .  .  KZ5DG  has  100  coun- 
tries confirmed  on  'phone  on  15  meters.  Grace  became  tlie 
first  station  in  the  western  hemisphere  to  contact  Gambia 
on  15  meters  when  she  worked  ZD.3BFC  in  March  (only 
station  in  that  country  on  that  band).  When  FM7WN  put 
Martinique  on  the  15-meter  band  in  April,  Grace  was  his 
first  contact.  .  .  .  WN0AYQ.  of  Ladue,  Mo.,  can  be  num-

(1))  Broadcasting: 

Melba  (famous  opera  and  concert  star)  sang 
over  the  Marconi  radiophone  station  in  Chelms- 
ford, England. ^^ 

The  De  Forest  Company  began  sending  out 
nightly  news-service,  on  1,650  meters,  with  a  1-kw. 
radiophone  located  on  top  of  the  World's  Tower 
Building,  New  York  City.^^ 

The  Naval  Communications  Service  broadcast 
a  concert  given  by  Mme.  Tettrazini.  This  orig- 
inated in  her  apartment  at  the  McAlpin  Hotel 
(in  New  York  City),  and  was  sent,  via  Bell  Tele- 
phone, to  the  Naval  Communication  Service's 
station  at  44  Whitehall  St.*"^ 

In  "Strays,"  the  following  appeared,  on  page 
47  of  the  February,  1921,  issue:  "Wondering  who 
KDKA  is'  Westinghouse  Elec.  &  Mfg.  Co.,  East 
Pittsburgh,  375  meters." 

Later,  in  1921,  a  church  in  Pittsburgh  made  a 
practice  of  picking  up  KDKA's  church  service 
broadcast  each  Sunday  and  delivering  it  to  the 
parishioners  via  a  loudspeaker  installed  in  the 
pulpit.^^ 

(c)  Ship-to-shore  radiotelephone:

A.T.&T.  "bought  into"  the  R.C.A.'*^ 
Near  Jacksonville,  Florida,  the  Lybeck  Ocean 
Harvester  Co.  installed  a  radiophone  on  one  of  its 
fishing  craft,  and  began  experimental  contacts 
with  shore  on  350  meters.^* 

(d)  "Firsts"  or  "Near-Firsts": 

The  QSL  card  for  use  in  reporting  amateur 
signals  over  distances  of  500  miles  was  first  sug- 
gested.^^ 

A  radiotelephone  mounted  in  an  automobile, 
was  exhibited  (by  SDR)  at  the  annual  outing 
of  the  Radio  Engineering  Society  of  Pittsburgh, 
held  on  July  18,  1920.*' 

At  station  4BQ  (Rome,  Georgia),  an  arrange- 
ment whereby  a  telephone  line  could  be  con- 
nected to  a  radio  receiver  was  in  operation.  It 
was  used  to  distribute  distant  radio  concerts  to 
friends.*^ 

The  May,  1921,  issue  of  QST  contained  the

one  now  in  existence,  dealing  with  the  basic 
theory  of  amateur  radio  in  a  way  that  will  give 
every  amateur  operator  a  clear  theoretical  under- 
standing of  how  his  apparatus  functions  so  that 
he  may  experiment  intelligently  and  not  hap- 
hazardly; and  a  book  that  will  likewise  serve  as  a 
text  for  the  non-technically  trained  individuals 
who  in  increasing  numbers  are  taking  up  the 
study  of  Citizen  Wireless."  '*^ 

(e)  "Curiosities": 

The  editor  of  QST  announced  that  he  had 
on  hand  enough  "Calls  Heard"  lists  submitted 
by  amateurs  to  fill  several  thousand  pages  of  the 
magazine. ^^ 

Station  9ZN  covered  the  Moran-Leonard  fight, 
at  East  Chicago  (20  miles  from  the  "windy 
city")  with  a  De  Forest  radiophone  and  a  port- 
able ^-kw.  radiotelegraph  spark  transmitter. 
This  was  done  for  the  Chicago  "Herald  Exam- 
iner". ^^ 

Arthur  W.  S.  Davis  (ILD,  of  Lowell,  Massa- 
chusetts), an  elderly  amateur,  had  his  radio  sta- 
tion moved  into  his  sick  room,  during  his  last 
illness:  and  he  "worked  it"  almost  up  to  the  last 
minute  of  his  life.^^ 

Radio  8ZW  purchased  550- Volt  D.C.,  for  his 
c.w.  set  from  the  trolley  company  for  50fi  per 
month.^'^ 

At  radio  6WN  (San  Diego,  California),  a  5- 
step  amplifier  allowed  the  signals  of  6MZ  (Del 
Mar,  California)  to  be  read  by  sense  of  touch.^^ 

In  this  "Foreword"  I  have  been  able  to  men- 
tion only  the  "high-spots"  of  this  remarkably- 
interesting  Volume  of  the  magazine.  An  examina- 
tion of  the  Index  itself  will  "fill  in  the  details." 
"All-in-all,"  Volume  IV  merits  plenty  of  atten- 
tion.

Editor,  QST: 

I'll  bet  you  a  wooden  nickel  I  can  identify  the  "un- 
licensed" station  "DA"  mentioned  on  page  50  of  March 
QST.  That  has  been  so  long  ago  I  won't  have  to  take 
refuge  under  the  Fifth  Amendment. 

I  believe  this  was  a  rig  using  4  Na\'y  VTls  and  using  B 
batteries  for  plate  voltage. 

To  my  personal  knowledge  this  transmitter  was  used  at 
Seagate  —  old  VVST-NAH7  —  with  regular  station  an- 
tenna, but  I  believe  it  was  also  used  at  several  other  loca- 
tions around  Brooklvn  and  New  York  City.   .   .   .

.  .  .  Financially,  SWL  QSLs  are  embarrassing.  If  I  had 
replied  to  all  the  QSLs  and  letters  that  I've  received  from 
SWLs  since  going  high  power  (for  Canada  at  any  rate)  I'd 
have  had  to  spend  4fi  per  card  as  well  as  4^  for  mailing  that 
card,  and  for  the  SWL  cards  that  I've  received  without  the 
International  Reply  Coupons  alone,  it  would  have  cost  me 
$38.04.  Now  I  ask  you  —  is  that  fair?

.  .  .  Being  a  KG6  SWL  I  spend  a  good  part  of  my  tin  e 
listening  in  on  20  meters  out  here  in  Guam. 

After  spending  a  few  hours  drawing  up  a  card  with  the 
help  of  a  local  ham,  and  a  few  more  photographing  and 
printing  the  cards  up,  I  was  in  business,  .\fter  listening  to  so 
many  stations  saying  they  QSL  100  per  cent  I  thought  that 
I  would  do  pretty  good,  so  started  mailing  out  the  cards. 
All  the  cards  go  airmail  and  it  must  not  be  local  stuff  as 
most  of  them  cost  me  twenty  five  cents  airmail.  Also 
enclosed  are  the  proper  amount  of  International  Reply 
Coupons.  I  have  a  few  hundred  dollars  worth  of  radio  to 
SWL  with  and  don't  liave  too  much  trouble  hearing 
stations  all  over  the  world. 

What  I  would  like  to  know  is  the  secret  to  get  some  QSL 
cards  in  return,  .^fter  a  few  months  of  trying  I  have  received 
one  from  a  W6  and  one  from  a  PY2.  Haven't  given  up 
trying  as  I  sent  out  15  more  this  morning.

Editor,  QST: 

...  I  wonder  if  Mr.  Proetz  (J\Iay  QST,  p.  54)  can  give 
me  an  answer  for  the  following?  On  May  6,  1952,  at  6.25 
P.M.  EST,  I  worked  VQ2DT,  Dave  R.  Taylor  of  Kitwe, 
Northern  Rhodesia.  I  sent  a  QSL  to  him  that  same  daj' 
followed  at  decent  intervals  by  others,  then  a  letter.  No 
answer  to  any  of  them.  Tlien  on  March  6,  1953,  I  sent 
another  letter  containing  five  International  Rei>ly  Coupons. 
I  still  have  not  received  his  QSL.  On  .lanuary  6,  1952,  at 
3:2.")  P.M.  EST,  contacted  VQ3CP,  J.  A.  Doxsey  of  Mwanza, 
Tanganyika.  QSL  card  sent  that  day  and  subsequent  ones, 
also  a  letter,  but  no  reply.  March  6.  1953,  I  sent  him  an 
airmail  letter  containing  five  International  Reply  Coupons, 
but  to  date  1  have  no  QSL  from  liim.  The  same  situation 
prevailed  with  VQ4ERH  of  Nairobi,  Kenya. 

Doesn't  Mr.  Proetz  realize  that  QSL  cards  are  re(iuired 
by  .\RRL  and  other  organizations  for  purposes  of  verifica- 
tion when  certain  certificates  are  applied  for?  And  may  I

PHENOMENON 

Jefferson  City 
Missouri 
Editor,  QST: 

.  .  .  On  an  average  of  one  night  every  three  or  four 
months  during  the  period  of  the  new  moon  at  about  mid- 
night there  is  an  echo  on  signals  in  the  2800-kc.  region. 
A  number  of  us  on  the  Missouri  State  Highway  Patrol  c.w. 
net  on  this  band  have  noticed  the  effect  and  no  two  agree 
on  the  cause.  Our  c.w.  receivers  are  wired  for  full  break-in, 
and  on  the  nights  in  question,  the  operator  can  hear  his 
own  transmitted  signal  with  a  strength  of  about  S8  and  a 
delay  of  up  to  about  2  seconds. 

The  only  details  I  can  supply  are  these:  The  effect  is 
usually  first  noticed  about  midnight  at  the  station  at  St. 
Josepli,  and  here  in  Jefferson  City  anywhere  from  30 
minutes  to  2  hours  later.  It  seems  to  move  in  a  south- 
easterly direction,  usually  observed  at  Poplar  Bluff  a  half 
hour  later  than  here.  Some  nights  only  one  or  two  stations 
will  notice  the  effect,  but  once,  about  three  years  ago,  all 
of  the  Missouri  stations  heard  it.  The  echo  is  never  heard 
by  any  but  the  transmitting  station.  The  duration  of  the 
effect  varies  from  about  5  minutes  to  an  hour. 

Normally,  on  something  like  this,  the  cause  might  be 
attributed  to  too  much  "cough  medicine,"  but  with  old- 
timers  like  W0BNQ,  W5BMI,  W0KG,  W0RTG,  W0ZAO, 
and  a  few  others  to  vouch  for  me,  I  feel  that  someone  else 
has  probably  noticed  it  too.  Anyone  want  to  volunteer 
a  good  explanation?

WHY  SINES? 

5704  Ben  Alder 
Whittier,  Calif. 
Editor,  QST: 

Just  finished  reading  "YB's"  letter  in  the  April  issue 
of  QST  (page  52)  and  would  like  to  add  my  two-bits  to  his. 
Having  worked  as  railroad  telegrapher  and  train  dis- 
patcher for  27  years  I  agree  with  "YB"  that  we  should 
receipt  for  messages  with  our  "sine,"  but  it  is  nice,  when 
just  rag-chewing,  to  know  the  other  fellow's  name. 

—  J.  E.  Muncey,  WOHUJ 

1178  High  Street 
Central  Falls,  R.  I. 
Editor,  QST: 

.  .  .  Well,  "YB,"  I  tried  your  system  on  c.w.,  but 
I  must  say  it  doesn't  fare  too  well!  I  used  "PB"  instead  of 
"Paul"  for  a  sine,  and  7  out  of  10  replied,  without  fail, 
".  .  .  NAME  OM?  PSE  KPT  NAME  OM"  or  better 
still,  "CFM  NAME  PB  IMI  IMI."  I  got  sick  of  this  and 
went  back  to  my  old  stand-by,  P-A-U-L,  and  nobody 
ventured  a  query.  When  one  comes  right  down  to  it,  if 
W70E  ever  gave  me  "  YB"  for  his  name,  I'd  query  quite  a 
bit  also.  So,  Howard,  we  are  not  all  telegraph  office  operators 
and  I'm  afraid  legible  names  will  have  to  be  used  if  we 
want  to  save  gray  hairs!  The  initial  "sine"  system  has  some 
value,  though  —  don't  throw  it  out  yet!  Of  most  practical 
use  would  be  on  NTS  —  our  .\RRL  c.w.  traffic  nets,  where 
tlie  use  of  names  is  totally  unnecessary.  But  then,  the  call 
is  sufficient  so  why  bother  with  sinos  at  all?

(1)  Advertising  shall  pertain  to  radio  and  shall  be  of 
nature  of  interest  to  radio  amateurs  or  experimenters  in 
their  pursuit  of  the  art. 

(2)  No  display  of  any  character  will  be  accepted,  nor  can 
any  special  typographical  arrangement,  such  as  all  or  part 
capital  letters  be  used  which  would  tend  to  make  one  adver- 
tisement stand  out  from  the  others.  No  Box  Reply  Service 
can  be  maintained  in  these  columns. 

(3)  The  Ham-Ad  rate  is  iO(  per  word,  except  as  noted  in 
paragraph  (6)  below. 

(4)  Remittance  in  full  must  accompany  copy.  No 
cash  or  contract  discount  or  agency  commission  will 
be  allowed. 

(5)  Closing  date  for  Ham-Ads  is  the  20th  of  the  second 
month  preceding  publication  dale. 

(6)  A  special  rate  of  70  per  word  will  apply  to  adver- 
tising which,  in  our  judgment,  is  obviously  non- 
commercial in  nature,  and  is  placed  and  signed  by  a 
member  of  the  American  Radio  Relay  League.  Thus, 
advertising  of  bona  fide  surplus  equipment  owned,  used  and 
or  sale  by  an  individual  or  apparatus  offered  for  exchange  or 
advertising  inquiring  for  special  equipment,  if  by  a  member 
of  the  American  Radio  Relay  League  take  the  7p  rate.  An 
attempt  to  deal  in  apparatus  in  quantity  for  profit,  even 
if  by  an  individual,  is  commercial  and  all  advertising  by 
him  takes  the  iOt  rate.  Provisions  of  paragraphs  (1),  (2) 
and  (5),  apply  to  all  advertising  in  this  column  regardless 
of  which  rate  may  apply.  To  expedite  handling  of  your 
copy  please  state  whether  you  are  a  member  of  ARRL. 

(7)  Because  error  is  more  easily  avoided,  it  is  re- 
quested signature  and  address  be  printed  plainly. 
Typewritten  copy  preferred,  but  handwritten  signa- 
ture must  accompany  all  authorized  insertions. 

(8)   No  advertiser  may  use  more  than   100  words  in  any 
one  issue  nor  more  than  one  ad  in  one  issue. 


Having  made  no  investigation  of  the  advertisers  in  the  classified

integrity  or  for  the  grade  or  character  of  the  products  or  services

DEAR  FELLOW  AMATEUR:  — 


"^ 


very  serious  situation 
has  arisen.  Unless  all  of  us 
amateurs  act  quickly,  a  law 
will  be  passed  in  Washing- 
ton which  will  wipe  Amateur 
Wireless  completely  out  .  .  ." 

Thus  in  1918  a  four-year-old 
AFIRL,  already  the  guardian 
of  amateur  radio  in  regulatory 
matters,  wrote  each  amateur  in 
the  United  States,  trying  to  pre- 
vent the  extinction  of  "amateur 
wireless." 

Wouldn't  you  be  astounded 
to  receive  such  an  urgent 
call  from  ARRL  today? 

Certainly  you  would.  Today, 
amateur  radio  is  a  strong, 
stable  group,  represented  by  a 
capable  ARRL  in  battles  to  pre- 
serve amateur  privileges.  Such 
representation,  backed  by  a 
united  membership,  alone  has 
kept  amateur  radio  on  the  air, 
contributing  to  the  pubhc  good. 

Are  you  doing  your  part?  The 
first  step  is  to  take  your  place 
in  the  ranks  of  organized  ama- 
teurs. Join  the  League  today!

LEADING  AMATEUR  DESIGNS 

...  Use  nRCA  Power  Tubes 


Take  Gonset's  Model  500-W  power 
amplifier,  for  example. 

Solidly  designed  to  meet  the  pres- 
ent and  the  future  transmitter  needs 
of  progressive  amateurs,  this  multi- 
purpose rf  power  amplifier  is  built 
to  "deliver  the  goods"— using  four 
RCA-807's  in  parallel. 

Why  is  RCA  the  choice  of  both 
the  commercial  transmitter  designer 
AND  the  amateur? 

RCA  power  tubes  are  built  to 
"take  it."  They  are  conservatively 
rated  and  reliable.  They  have  great 
reserve  of  emission.  They  have  "high 


perveance"  design— deliver  higt 
power  output  at  lower  plate  volt- 
ages. RCA  power  tubes  arp 
ECONOMICAL. 

RCA  has  a  comprehensive  line  o. 
high-perveance  beam  power  tubes 
and  triodes  to  meet  every  amateur 
power  input  requirement— up  to  a 
"gallon."  They're  available  at  your* 
RCA  Tube  Distributor.  For  technic? '

A  peak  in  the  response  curve  limits 
modulation  to  the  peal<  value.  A  peak-free 
response  brings  the  full  power  level  to 
100%  modulation  gaining  an  inteliigibiiity 
increase  equal  to  the  peak  in  the  average 
mike.  The  664  is  peak-free  and  gives  the 
highest  usable  power  of  any  microphone 
for  AM,  NFM  and  SSB. 

See  your  E-V  Distributor, 

or  vfrito  for  Specification  Shoet 


The  664  will  equal  a  useful  power  increase 
of  four  times  over  commonly-used  peaked 
microphones,  and  could  well  be  the  best 
investment,  dollar-wise,  in  your  shack 


Here  is  a  totally  new  concept  in  microphones  for 
amateur  phone  communication. 

The  cardioid  (high  directivity  at  all  frequencies) 
pickup  pattern  enables  you  to  have  a  real  "arm  chair 
QSO."  The  forward  gain  of  5  db**  allows  you  to  speak 
at  nearly  twice  the  distance  you  have  been  working  to 
a  conventional  microphone.  Unwanted  sounds  in  the 
shack  are  rejected  nearly  twice  as  effectively  as  by 
ordinarily-used  non-directional  microphones. 

The  response  curve  is  tailored  to  put  the  highest 
degree  of  intelligibility  on  your  carrier.  Your  100% 
modulation  is  all  speech  ...  in  full  character  .  .  .  with 
bite  and  punch.  This  curve,  compared  to  ordinary 
microphones,  will  give  you  up  to  12  db  more  usable 
audio — without  splatter  or  hash. 

We  invite  you  to  prove  to  yourself  that  the  664  will 
outperform  your  present  mike  by  a  direct  comparison. 
If  it  doesn't  out-hurdle  QRM,  your  distributor  will 
refund  the  purchase  price  without  qualification. 


New  Variable  D*  Dynamic  Microplione  operates  on  tlie  prin- 
ciple of  multiple  sound  paths  to  the  diaphragm.  Spaced 
apertures  to  the  rear  of  the  diaphragm  are  phased  to  pro- 
vide cancellation  of  rear  sounds  and  give  full  response  to 
sound  from  the  front. 

This  new  principle  enables  the  curve  to  be  free  from  peaks 
or  dips.  Insures  freedom  of  blasting  and  boominess  from 
close  talking.  Eliminates  effect  from  mechanical  shock. 
High  level  -55  db.  Acoustalloy  diaphragm.  Switch  easily 
changed  to  relay  control,  if  desired.  Absolutely  unaffected 
by  moisture,  humidity,  or  temperature. 

Model  664.  Without  Stand Net  Price:  $47.70 

Model  419.  Desk  Stand Net:      9.00

•  Right:  the  "why"  of  G-E  "Operation  Snow  White".  Unretouched  micro- 
photograph  of  tube  grid,  shows  a  strand  of  lint  which  can  easily  cause 
an  inter-electrode  short-circuit.  Dust  particles  have  similar  effect. 


•  Glass-paneled  hoods  for  General  Electric 
5-Star  Tube  assembly  and  microscope  inspec- 
tion, assure  working  conditions  of  optimum 
cleanliness.  Employees  wear  rubber  finger  cots, 


to  avoid  contaminating  tube  parts  with  dirt  or 
moisture.  The  entire  "Snow  White"  area  is  air- 
conditioned  and  pressurized,  and  all  garments 
are  made  of  lint-free  Nylon  and  Dacron. 


G-E  "Operation  Snow  White"  furtlier  increases

i 


inoperatives  among  5-Star  Tubes  have 
been  cut  two-thirds  by  measures  G.E. 
has  taken  to  provide  lint-free,  dust-free 
assembly  and  inspection.  100%  5-Star 
factory  tests  prove  this  gain  in  built-in 
tube  dependability. 

Most  tube  inoperatives  are  the  result 
of  intermittent  "shorts"  from  lint  and 
dust.  G-E  "Operation  Snow  White",  by 
means  of  pressurized,  filtered,  and  de- 
humidified air,  plus  numerous  other 
steps  to  accent  working  cleanliness,  cuts 
down  on  short-circuits  at  the  source. 
Result:  5-Star  Tubes  are  the  most  trust- 


worthy types  that  you  can  install ! 

Use  them  in  civil-defense  work,  where 
dependable  communications  are  a 
"must"!  Specially  designed,  built,  and 
tested,  they're  your  foremost  protection 
against  rig  and  receiver  failures.

CRYSTAL 
CONTROLLED 

BUT  NOT 
ROCK  BOUND" 


Skip  around  as  your  heart  desires  ...  be  a 
bandhopper  with  a  vengeance  .  . .  and  yet 
retain  the  priceless  advantages  of  crystal 
control.  All  you  need  is  a  half-dozen  or 
more  PRs.  Multiple  crystal  operation  is  the 
answer  to  today's  maddening  QRM  prob- 
lems on  phone  or  CW.  It's  most  economical, 
too.  See  your  jobber  and  select  low-cost 
PRs  from  his  all-frequencies  stock.  Be  a 
gypsy  on  the  band.

^^^  AMERICAN 
RADIO  RELAY 
LEAGUE 


INC., 


is  a  noncommercial  association  of  radio  amateurs,  bonded  for 
the  promotion  of  interest  in  amateur  radio  communication  and 
experimentation,  for  the  relaying  of  messages  by  radio,  for  the 
odvancement  of  the  radio  art  and  of  the  pubh'c  welfare,  for  the 
representation  of  the  radio  amateur  in  legislative  matters,  and  for 
the  maintenance  of  fraternalism  and  a  high  standard  of  conduct. 

It  is  an  incorporated  association  without  capital  stock,  chartered 
under  the  laws  of  Connecticut.  Its  affairs  are  governed  by  a  Board 
of  Directors,  elected  every  two  years  by  the  general  membership. 
The  officers  are  elected  or  appointed  by  the  Directors.  The  League 
is  noncommercial  and  no  one  commercially  engaged  in  the  manu- 
facture, sale  or  rental  of  radio  apparatus  is  eligible  to  membership 
on  its  board. 

"Of,  by  and  for  the  amateur,"  it  numbers  within  its  ranks  practi- 
cally every  worth-while  amateur  in  the  nation  and  has  a  history  of 
glorious  achievement  as  the  standard-bearer  in  amateur  affairs. 

Inquiries  regarding  membership  are  solicited..  A  bona  fide 
interest  in  omoteur  radio  is  the  only  essential  qualification,-  owner- 
ship of  a  transmitting  station  and  knowledge  of  the  code  are  not 
prerequisite,  although  full  voting  membership  is  granted  only  to 
licensed  amateurs. 

All  general  correspondence  should  be  addressed  to  the,  adminis- 
trative headquarters  at  West  Hartford,  Connecticut.

It  Seems  to  Us..." 


ELECTIONS 

Our  frequent  contention  that  amateurs  are 
pretty  much  a  cross-section  of  the  population 
is  borne  out  in  yet  another  way  by  comparing 
the  percentage  of  votes  cast  in  ARRL  director 
elections  with  those  of  national  political  elec- 
tions. Over  the  past  six  U.  S.  Presidential  elec- 
tions the  national  vote  has  ranged  from  51  to 
62.7  per  cent,  while  in  the  League's  director 
elections  the  vote,  in  the  past  five  years,  has 
ranged  nationally  from  53  to  59  per  cent,  with 
some  division  votes  as  low  as  48,  and  some  as 
high  as  65,  per  cent  of  those  eligible.  These 
figures  show  that,  by  and  large,  amateurs  are 
as  interested  in  the  affairs  of  their  organization 
as  citizens  generally  are  in  national  affairs. 
This,  to  us,  is  a  sign  of  the  strength  of  the 
organized  amateur  movement,  and  speaks  well 
of  amateurs  as  a  grouj). 

But  curiosity  moves  us  —  what  happens  to 
the  other  forty  per  cent?  Have  they  an  active 
interest  in  League  affairs?  Do  they  realize  that 
the  ARRL  directors  are  the  people  who  make 
the  long-range  plans  and  decide  i)olicy  matters 
for  all  League  members?  .  .  .  that  men  of 
judgment  and  wisdom  are  needed?  If  they  did, 
it  would  seem  that  the  vote  would  be  nearly 
100  per  cent,  for  all  would  be  anxious  to 
choose  the  man  they  believe  most  qualified 
for  the  director  position. 

The  usual  reasons  why  one  may  not  be  able 
to  cast  a  ballot  in  a  political  election  don't 
often  operate  in  League  elections.  Transporta- 
tion to  the  polls  is  no  problem  —  the  ballot- 
box  is  your  mail  box.  The  difficulty  in  obtain- 
ing absentee  ballots  doesn't  apply  —  all  our 
votes  are  "absentee."  Temporary  absence 
from  town  on  business  won't  stjonie  you  —  the 
voting  goes  on  continuously  from  October  first 
to  November  twentieth. 

One  more  thing  is  important  —  you  can't 
vote  for  the  man  j^ou  think  best  if  his  name 
isn't  on  the  ballot!  Don't  leave  it  to  someone 
else  —  if  you  have  someone  in  mind  you  be- 
lieve has  the  ciuaUties  and  qualifications  of 
directorship,  get  up  a  nominating  petition 
signed  bj^  ten  or  more  Full  INI  embers,  and  send 
it  into  the  Secretary  before  the  20th  of  Sep- 
tember. 


Let's  make  a  new  record  for  participation 
in  this  autumn's  election  in  the  Atlantic, 
Canadian,  Dakota,  Delta,  Great  Lakes,  Mid- 
west, Pacific  and  Southeastern  Divisions.  Full 
details  are  on  page  50. 

MOBILE  MANUAL 

League  Hq.  takes  pleasure  in  announcing 
the  prei^aration  of  a  new  publication.  The 
Mobile  Manual  for  Radio  Amateurs,  another 
addition  to  the  ARRL  Radio  Amateur's  Li- 
brarv.  Now  printing,  it  will  be  available  some- 
time in  August. 

Like  its  slightly  older  l;)rother.  Single  Side- 
band, the  mobile  manual  is  another  demonstra- 
tion of  the  thorough  coverage  QST  provides  in 
a  specialized  field,  in  this  case  mobile  —  for 
nearly  all  the  material  has  come  from  the 
pages  of  our  monthly  journal  over  the  past 
few  years.  The  result  is  what  you  might  expect 
—  a  veritable  encyclopedia  on  mobile  tech- 
niques —  design,  construction,  installation  and 
operation. 

0-R-MARY 

One  of  the  most  important  and  useful  tools 
of  the  voice  operator  is  phonetics,  ^^^len  con- 
ditions are  rough  and  readibility  is  poor,  the 
use  of  phonetics  can  be  the  difference  between 
communication  and  no  communication.  It 
seems  to  us,  however,  that  sometimes  we  carry 
it  to  extreme. 

In  identifying  your  call  sign,  by  all  means 
use  phonetics  —  an^'time.  But  when  a  'phone 
signal  is  Readability  5  (and  except  in  DX, 
whoever  heartl  a  lesser  report?)  the  only  other 
reason  to  use  phonetics  is  something  like  trans- 
mitting a  trick  word,  or  the  address  of  a  mes- 
sage. Yet  3'^ou've  heard  many  an  R5  voice  say- 
ing, "...  here  in  Schenectady,  S-Susan,  C- 
Charlie,  H-Henry.  .  .  .  "  Or  it  might  be  Phil- 
adelphia or  Detroit,  Springfield  or  Milwaukee. 
Or  simple  operator  names  like  Joe  and  Bill. 
There's  no  need  for  such  phonetics  unless  j^our 
name  is  Zzyinsklf  or  unless  you  five  in  Bfftsplk 
Park. 

Queen-Roger-Mary  and  Queen-Tare- 
Charlie  are  other  cases  in  point.  It  has  always 
been  a  source  of  amazement  that  so  many  of  us 


install  a  modulator  for  the  enjoyment  of  voice 
communication,  and  then  contmue  to  use 
abbreviation  methods  which  were  designed  tor 
teleo-raphy  and  never  would  have  come  into 
existence  without  their  need  in  telegraphing. 
"QRM"  is  for  the  c.w.  operator,  to  save  his 
time  in  otherwise  having  to  spell  out  "inter- 
ference "  Voice  frees  the  operator  from  the 
need  for  such  abbreviations.  'Phone  is  much 
too  useful  a  system  of  communication  to  be 
burdened  with  techniques  designed  for  an

The  somewhat  dubious  honor  of  being  the  first 
ham  to  cause  TVI  may  belong  to  Tom  Marshall, 
W5RFF.  Here's  his  story:  "Back  in  1936  or  '37 
New  Haven,  Conn.,  was  celebrating  its  300th 
birthday,  and  I  set  up  a  ham  station  at  a  booth 
in  the  armory.  Among  the  exhibitions  was  a 
demonstration  of  television  by  the  Baird  outfit  — 
scanning  disk,  neon-bulb  receiver,  and  so  on. 
During  one  of  the  TV  shows  the  director  came 
screaming  out  of  the  darkened  tent  and  made 
straight  for  the  ham  station  — yep,  we  were 
taking  his  picture  out!  To  keep  peace,  we  installed 
a  push-button  at  the  TV  demonstration  and  a  red 
light  at  our  station,  so  when  the  light  went  on  we 
stayed  off."  .  , 

As  W5RFF  says,  "What  a  claim!'    But  its 
probably  another  ham  "first."

An  Improved  Antenna  Bridge 

Increased  Accuracy  and  Convenience  in  Impedance  Measurements 
BY  R.  WADE  CAYWOOD,*  WIKRD 


•  Most  earlier  designs  of  simple  variable- 
impedance  bridges  for  antenna  and 
otbcr  r.f.  impedance  nieasiiremenls  have 
been  open  to  serious  objections  because 
of  inherent  inaccuracies.  Described  here 
is  a  circuit  that  overcomes  these  objec- 
tions and  offers  greater  convenience  in 
operation.  Also  described  is  a  balun  of 
novel  construction  for  eliminating  errors 
in  measurements  on  balanced  lines  and 
loads. 


IT  is  often  desirable  to  determine  the  resistance 
and  resonant  frequency  of  an  antenna,  to 
check  the  standing-wave  ratio  on  a  transmis- 
sion Une,  to  find  receiver-input  impedance,  and 
to  make  many  other  r.f.  impedance  measure- 
ments. The  antenna  bridge  descrilied  here  offers 
an  improved  means  for  making  these  measure- 
ments, and  at  the  same  time  is  simple  in  design 
and  easy  to  construct  and  use. 

Fig.  lA  is  the  fundamental  circuit  of  a  stand- 
ard Wheatstonc  bridge.  P'ig.  IB  shows  two  adap- 
tations of  the  Wheatstone  bridge  for  radio- 
freciuency  measurements;  the  similarity  Ix'twecn 
these  diagrams  and  the  basic  d.c.  resistance  bridge 
is  obvious.  In  the  development  of  such  bridges,  a 
subsequent  step  was  that  of  using  the  adaptation 
in  Fig.  IB  to  make  a  fixed-imi)edance  standing- 
wave-ratio  bridge.  The  schematic  circuit  diagram 
of  such  a  bridge  is  shown  in  Fig.  AC.  Ra  can  be  a 
51-ohm  carbon  resistor  for  50-olim  coaxial  line. 
The  two  ratio  arms  consisting  of  R^i'i  and  RzCz 
are  identical  so  that  the  bridge  unbalance  is 
minimum  when  the  impedance  connected  to  the 
output  jack  is  ecjual  to  51  ohms  and  is  a  pure 
resistance.  If  the  impedance  differs  from  51  ohms 
the  meter  reading  will  not  be  zero  and  the  in- 
strument can  be  calibrated  either  in  terms  of 
impedance  or  standing  wave  ratio.  However,  at 
impedances  other  than  51  ohms,  the  accuracy  of 
measurement  frequently  is  not  too  good.^ 

In  an  attempt  to  avoid  being  restricted  to  a 
fi.xed  impedance,  liridges  have  been  made  using  a 
potentiometer  in  one  arm.  This  seems  like  an 
obvious  solution,  but  there  are  several  disad- 
vantages to  this  type  of  bridge.  Principally,  there

1  This  is  partly  because  the  accuracy  of  such  a  bridge  tends 
to  decrease,  as  a  practical  matter,  with  an  increase  in  the 
ratio  of  the  impedances  in  the  unlcnown  and  standard  arms. 
Also,  as  has  been  pointed  out  many  times  in  QST  and  the 
Handbook,  for  accurate  measurement  it  is  essential  that  the 
indicating  circuit  have  good  linearity  and  extremely  high 
impedance  compared  with  the  bridge  impedance,  and  that 
the  r.f.  input  voltage  be  maintained  constant  wlien  the 
load  is  disconnected  or  short-circuited  for  the  reference 
voltmeter  setting.  —  Ed. 


is  a  substantial  frequency  error  because  a  poten- 
tiometer is  not  a  pure  resistance  but  a  combina- 
tion of  resistance  and  reactance,  and  as  the  arm  of 
the  potentiometer  is  moved,  the  ratio  of  resist- 
ance to  reactance  changes.  Hence  the  accuracy  of 
measurement  is  relatively  poor  and  the  calibra- 
tion depends  on  frecjuency.  Thus  the  substitution 
of  a  potentiometer  in  the  simple  fixed-resistance 
l)ridge  is  not  too  good  a  solution. 

A  disadvantage  of  bridges  using  all  resistance 
arms  is  that  the  r.f.  power  requirements,  while 
not  large  in  terms  of  watts,  are  often  greater  than 
can  be  supplied  1)\"  a  grid-dip  meter.  It  therefore 
becomes  necessary  to  use  a  transmitter  to  supply 
the  power,  but  since  even  a  low-power  transmitter 
generally  has  an  output  sufficient  to  overload  the 
bridge  components,  some  provision  must  be 
made  for  reducing  the  power  to  the  proper  level. 
A  grill-dip  meter  would  be  a  more  convenient 
power  source. 

A  circuit  suggested  by  S.  W.  Seeley,  W2ZE, 
offers  the  possibility  of  very  considerable  im- 
provement in  both  respects.  In  this  arrangement 
a  differential  cai)acitor  supplies  the  variable 
comi)onents  of  an  adjustable-impedance  bridge, 
and  since  capacitance  can   be  measured  much

and  C3  in  this  circuit  are  blocking  capacitors.

The  simplicity  of  the  hridge  is  evident  from  its  ap- 
pearance. The  unknown  impedance  to  be  measured  is 
connected  to  the  coaxial  jack  on  the  side,  and  r.f.  from  a 
grid-dip  meter  is  coupled  to  the  loop  at  the  left. 

more  accurately  than  resistance  at  r.f.,  and  can 
easily  be  kept  "pure"  at  ordinary  frequencies, 
a  high  order  of  bridge  accuracy  becomes  possible. 
A  differential  capacitor  is  a  dual  capacitor  so 
arranged  that  as  the  shaft  is  turned  the  capaci- 
tance of  one  unit  decreases  by  the  same  amount 
that  the  capacitance  of  the  other  increases;  in  a 
bridge,  the  two  capacitors  become  the  variable 
ratio  arms.  The  practical  form  of  W2ZE's  circuit 
is  shown  in  Fig.  2,  where  Ci  is  the  differential 
capacitor.  Ci  does  not  use  up  any  of  the  r.f.  input 
power,  and  when  a  microammeter  is  used  as  an 
indicator,  the  circuit  will  operate  well  from  a  grid- 
dip  meter  source  even  with  loose  coupling. 

The  only  fussy  part  of  the  bridge  is  the  differ- 
ential capacitor.  For  compactness  and  reduction 
of  stray  effects  this  capacitor,  like  the  one  shown 
in  the  accompanying  photograph,  should  be  de- 
signed especially  for  the  purpose.  Two  identical 
single  capacitors,  ganged  together  so  that  one  is 
at  maximum  when  the  other  is  at  minimum 
capacitance,  may  be  usable;  however,  the  fre- 
quency error  will  be  greater  even  though  the 
assembly  is  kept  as  compact  as  possible  to  mini- 
mize stray  inductance. 


Construction 

The  photographs  show  the  construction  of  a 
bridge  l)uilt  to  \V2ZE's  design.  As  can  l)e  seen  by 
looking  at  the  inside  view,  the  unit  is  not  at  all 
complicated;  however,  it  is  advisable  to  stick  to 
the  suggested  components  and  layout.  Obviously 
it  is  undesirable  to  have  unnecessary  lead  in- 
ductances or  capacitances  between  bridge  arms. 
As  shown  in  the  inside  view  of  the  bridge  and  in 
the  photograph  of  the  differential  capacitor,  a 
copper  shield  is  placed  around  the  top  part  of 
the  capacitor  to  shield  the  stators  from  the  other 
elements  of  the  bridge.  Since  the  calibration  ac- 
curacy at  the  upper  end  of  the  frequency  range  is 
limited  by  stray  capacitances  between  bridge 
elements,  the  addition  of  this  shielding  raises  the 
upper  frequency  limit  at  which  the  bridge  main- 
tains its  accuracy.  With  the  shield  around  the 
condenser  the  frequency  error  is  very  small  up  to 
at  least  50  Mc. 

The  choke  in  the  bridge  is  a  miniature  pow- 
dered-iron-core layer-wound  solenoid.  The  lead 


I  111-  clidciciilial  (Mpiicilor  wliich  is  tlii'  lirart  (il  llic 
liridgc  circuit.  The  copper  shielding  fastened  to  the 
rear  end  plate  is  to  prevent  stray  coupling  to  other 
components  in  the  bridge.

Any  revision  in  the  layout  that  results  in  longer 
leads  will  tend  to  result  in  increased  frequency 
error. 

The  Type  1N34A  germanium  diode  was  used 
because  it  is  satisfactory  and  because  it  is  gen- 
erally available.  Other  types  should  be  equally 
satisfactory,  however. 

R.f.  is  introduced  into  the  bridge  circuit 
through  the  crystal  socket  shown  at  the  bottom 
of  the  unit  in  the  inside  view.  Three  i)Iug-in 
pick-up  loops  are  used  for  coupling  the  out})ut 
of  a  grid-dip  meter  to  the  bridge.  These  coils 
have  1,  3  and  10  turns,  respectively,  and  are 
mounted  on  Millen  87412  300-ohm  transmission

1^2  inches  in  diameter,  resonates  in  the  bridge 
over  the  appro.ximate  range  5.2  to  8.8  Mc,  de-

pending  on  the  impedance  (that  is,  capacitor) 
setting.  The  3-tum  coupling  coil,  also  l}4  inches 
in  diameter,  resonates  from  15.5  to  30.5  Mc.  and 
the  1-tum  coupling  coil  (1  inch  in  diam- 
eter) resonates  from  32  to  84  Mc.  With 
the  bridge  set  to  50  ohms  the  lO-turn 
coil  and  the  3-turn  coil  result  in  the  same 
coupling  at  12  \lc.:  consequently,  thr 
10-tum  coupling  coil  should  he  used  for 
measurements  below  12  Mc.  The  3-tuni 
coil  and  the  1-turn  coil  result  in  ap- 
proximately the  same  coupling  at  40  Mc  : 
consequently,  the  3-turn  coil  should  l)i' 
used  for  measurements  between  12  and 
40  Mc.  and  the  1-turn  coil  should  be  uscil 
above  40  ]\Ic.  In  general,  the  coupling 
coil  closest  to  resonance  at  the  particular 
capacitor  setting  in  use  should  be  chosen. 
It  is,  of  course,  possible  to  make  cou- 
pling coils  that  will  be  resonant  at  the 
particular  frequency  for  which  a  meas- 
urement is  desired,  but  experience  has

shown  that  the  three  coils  suggested  cover  the 
range  adequately.  Other  coils  would  be  required 
only  under  certain  very  special  circumstances. 

The  3-turn  coupling  coil  was  made  by  thread- 
ing the  3  turns  through  a  piece  of  spaghetti  cut 
to  the  proper  length.  The  10-tum  hnk  can  be 
wrapped  in  insulating  tape  and  thoroughly 
doped  in  coil  cement,  or  the  coil  can  have  a 
coating  of  \dnylite  built  up  on  it  by  repeated 
dipping  in  liquid  vinylite  material  which  is  readily 
available  for  caulking  and  waterproofing.  This 
material  apparently  has  no  harmful  effect  upon 
the  coils. 

Calibration 

The  theoretical  calibration  of  angular  setting 
of  the  capacitor  rotor  vs.  impedance  is  a  shallow 
S-shajjed  curve,  when  plotted  on  semilog  paper, 
symmetrical  with  respect  to  the  design  center 
impedance.  The  curve  for  the  bridge  described 
here  is  shown  in  Fig.  3. 

A  similar  curve  can  be  constructed  for  a  given 
bridge  by  connecting  carbon  resistors  of  various 
values  between  5  and  500  ohms  to  the  output 
connector  and  adjusting  the  capacitor  for  a  null 
in  each  case,  using  a  calibrated  grid-dip  meter  as 
the  source  of  an  r.f.  voltage  of  knowii  frequency. 
A  similar  procedure  at  various  frequencies  within 
the  range  of  the  grid-dip  meter  will  show  whether 
there  is  any  appreciable  frequency  error,  and  if 
so,  the  freciuency  at  which  it  tends  to  become  im-

portant.  Lead  length  between  the  body  of  the  test 
resistor  and  Jo  should  be  kept  to  a  minimum, 
particularly  with  the  lower  resistance  values. 

For  highest  calibration  accuracy  the  test  re- 
sistors should  be  measured  with  an  accurate  re- 
sistance bridge  or  ohmmeter  so  their  actual  re- 
sistance is  known.  If  suitable  instruments  are  not 
available  for  measuring  the  resistances,  resistors 
having  5  per  cent  tolerances  or  less  should  be  used.

to  amateur  antenna  and  impedance  problems  in 
exactly-  the  same  wa>'  that  the  older-tyix"  bridges, 
both  fixed  and  variable,  have  been  applied.  Since 
this  subject  has  been  very  adequately  covered  in 
amateur  publications,  we  will  add  only  a  few  notes 
here.  The  only  real  difference  between  this  and 
the  previous  instruments  is  the  ease  with  which 
measurements  can  be  made  and  the  improved 


accuracy.  The  r.f.  input  to  the  bridge  is  not 
critical,  but  with  a  50-microampere  meter  move- 
ment such  as  is  used  in  the  circuit  sho\\^l,  the 
measurements  should  begin  with  loose  coupling  to 
avoid  the  possibility  of  damaging  the  meter. 
Actual  use  of  the  instrument  is  very  simjjle  and 
in  general  the  procedure  for  measuring  im- 
jjedance  is  as  follows: 

1)  Couple  an  r.f.  voltage  of  the  desired  fre- 
quency to  the  bridge. 

2)  Adjust  the  coupling  by  moving  either  the 
bridge  or  the  r.f.  source  so  that  the  meter  indi- 
cates about  40  microamperes. 

3)  Connect  the  unknown  impedance  to  Jz- 

4)  Adjust  the  dial  for  minimum  meter  reading. 

5)  Read  the  value  of  the  unknown  impedance 
from  the  calibration. 

In  this  connection,  it  should  be  noted  that  the 
imj)edance  being  measin-ed  may  not  be  a  pure  re- 
sistance, in  which  event  the  minimum  reading 
will  not  be  an  actual  null.  If  a  good  null  (meter 
reading  zero  or  very  close  to  it)  cannot  be  ob- 
tained, the  bridge  calibration  does  not  hold. 
(This  is  true  of  any  bridge  circuit  which  does  not 
incorporate  special  means  for  separating  the  re- 
sistive and  reactive  components  of  the  unknown 
impedance. )  Conversely,  a  complete  null  does  in- 
dicate that  the  unknown  impedance  is  a  pure  re- 
sistance. With  complex  unknowns,  the  reactive

of  well-known  methods,  leaving  only  the  resistive 
component  to  be  measured  by  the  bridge.  In  such 
a  case,  the  criterion  for  proper  reactance  com- 
pensation is  the  fact  that  the  null  is  complete. 

For  s.w.r.  checks  the  bridge  capacitor  should

object  being  to  adjust  the  matching  circuit  to 
obtain  the  lowest  possible  reading  on  the  meter.

Balanced  lines  or  loads  may  be  measured  with

form  of  such  circuit. 

The  Wound  Balun 

A  wound  balun  is  simply  an  accurate  2-to-l 
auto  transformer  with  the  residual  reactances 

2  Although  the  factors  mentioned  in  Footnote  1  do  not 
affect  the  accuracy  of  impedance  measurement  with  the 
bridge  described,  since  the  bridge  is  always  adjusted  for  a 
null  in  such  measurements,  they  do  apply  with  full  weight 
to  the  measurement  of  standing-wave  ratios  higher  than  1 
to  1.  For  s.w.r.  measurement,  provision  for  checking  the 
input  voltage  should  be  included  in  the  circuit  of  Fig.  2, 
and  a  resistance  of  at  least  10,000  ohms  —  preferably  as 
much  as  50,000  —  should  be  placed  in  series  with  the 
mieroammeter.  However,  tliese  precautions  are  not  neces- 
sary for  purely  qualitative  comparisons  nor  for  facilitating 
matching-circuit  adjustments  where  the  object  is  to  attain 
the  lowest  possible  meter  reading.  Most  amateur  uses  of  an 
s.w.r.  bridge  are  in  this  categorj'.  —  Ed.

A  balun  for  40  and  80  meters,  using 
ISO-ohm  Twin-Lead  (Amphenol  14-079 
or  Alpha  1151)  for  the  bifilar  winding. 
There  are  8  turns  of  Twin-Lead  on 
2^-inch  diameter  bakelite  tubing.  The 
shunt  tuning  capacitance  for  80  meters 
is  62  fifii.;  no  shunt  capacitor  is  needed 
for  40  meters.  The  scries  capacitance 
for  80  meters  is  0.0045  tii.  and  for  40 
meters  is  0.001  Aif- 

This  model  uses  a  female  coaxial

tuned  out  and  as  tight  coupling  as  possible  be- 
tween the  two  halves  of  its  total  winding.  If  the 
impedance  is  measured  between  a  grounded 
center-tap  and  one  terminal  of  the  winding  when 
a  balanced  load  is  connected  across  it,  the  2-to-l 
turns  ratio  produces  a  4-to-l  step-down  in  the 
impedance  measurement.  For  example,  a  prop- 
erh^-terminated  balanced  ()00-ohm  line  connected 
to  the  outside  terminals  of  the  winding  would  bo 
measured  as  150  ohms  between  the  grounded 
center-tap  and  either  end.  This  means  that  the 
readings  of  the  antenna  bridge  must  be  multijilied 
by  four  when  using  the  l)alun.  Thus  the  range  of  a 
51500-ohm  bridge^  becomes  20-2000  ohms  for 
balanced  loads.  This  coincides  with  the  usual 
higher  impedances  of  balanced  lines,  l^se  of  a 
balun  maintains  balance  during  measurement  and 
thus  obviates  the  wild  errors  usually  encountered 
when  one  tries  to  measure  any  balanced-line  im- 
pedance without  first  converting  it  to  a  single- 
ended  load. 

There  are  five  principal  requirements  for  the 
construction  of  an  accurate  wound  balun: 

1)  The  two  halves  of  the  winding  must  be  as 
nearly  equal  and  as  symmetrically  positioned  as 
possible. 

2)  The  coupling  between  the  two  halves  of  the 
winding  must  be  as  close  to  100  per  cent  as 
possi)>le. 

3)  The  Q  of  the  winding  must  be  high. 

4)  The  total  inductance  must  be  resonated  to 
the  frequency  of  operation  lay  a  shunt  capacitor 
across  the  balanced  terminals. 

5)  The  residual  leakage  reactances  should  be 
tuned  out  by  means  of  a  capacitor  in  series  with 
the  "hot"  single-ended  terminal. 

These  five  objectives  are  accomplished  in 
the  following  manner: 

Symmetry  and  tight  coupling,  (1)  and  (2),  are 
ol^tained  by  making  the  two  halves  of  the  winding 
bifilar.  In  the  10-20  meter  balun  illustrated  the 
2-inch  diameter  Incite  foi-m  is  wound  c^lth  its 
3-turn  windings  paired  in  double-thread,  7  t.p.i. 
lathe-cut  grooves.  In  winding,  the  wire  starts  at 
the  beginning  of  one  thread,  continues  for  three 
turns  to  the  end  of  that  thread,  goes  through  a 
hole  to  the  inside  of  the  form,  back  to  a  hole

leading  out  to  the  start  of  the  second  thread, 
then  continues  in  that  thread  for  three  more 
turns  to  the  end  of  the  winding.  The  center  of 
the  wire,  where  it  goes  from  the  end  of  the  first 
thread  to  the  beginning  of  the  second,  is  the  exact 
physical  (and  electrical)  center  of  the  two  wind- 
ings. That  point  is  joined  by  a  short,  heavy  strap 
directly  to  the  body  of  the  male  coaxial  connector. 
The  C>  of  the  illustrated  balun  turned  out  to  be 
235  at  14.3  Mc.,  which  is  the  equivalent  of  about 
a  50,000-ohm  resistor  in  shunt  with  the  balanced 
load  to  1)0  measured.  This  causes  an  error  of  about 
4  per  cent  in  the  reading  of  a  2000-ohm  load  but 
only  1  per  cent  for  a  500-ohm  load. 

When  this  balun  was  tuned  to  operate  at  28 
Mc,  it  showed  almost  exactly  the  same  shimt 
resistance.  Several  transmission-line  baluns  that 
were  tried  showed  four  to  five  times  the  error  of 
this  wound  balun  due  to  their  lower  Q. 

Tuning  out  the  residual  reactances  of  the 
wound  balun  can  bo  done  rather  easily  with  the 
aid  of  a  grid-dip  meter.  The  prol)lem  is  somewhat 
simplified  if  one  first  calculates  the  amount  of 
capacitance  recjuired  to  resonate  the  total  wind- 
ing to  the  center  of  the  frequency  band  in  which 
it  is  to  be  used.  In  the  case  of  the  illustrated 
balun,  the  Lightning  Calculator  indicated  2.6  ^h. 
which  would  rofiuiro  a  total  capacitance  of  49  M^f • 
to  resonate  it  to  the  center  of  the  20-meter  liai/d. 
It  was  estimated  that  the  coil  distributed  cai)aci- 
tance  would  be  about  10  M^f-  so  a  fixed  39-MMf- 
ceramic  was  connected  across  the  balanced  termi- 
nals. The  grid-dipper  then  showed  resonance  at 
14.3  Mc,  which  was  plenty  close  enough. 

At  first  it  was  thought  that  the  small  residual 
leakage  reactances  could  be  tolerated  without  a 
correcting  condenser  in  series  with  the  single- 
ended  output.  But  it  turned  out  to  be  such  an 
eas>'  job  to  find  the  correct  value  and  put  it  in, 
and  the  increased  accuracy  thus  gained  was  so 
immediately  apparent,  that  it  seems  well  worth 
while  to  include  it. 

As  a  starter,  it  was  assumed  that  the  leakage 
inductance  of  the  coil  and  leads  would  be  some- 
where in  the  neighborhood  of  2  to  3  per  cent  of 
the  total  coil  inductance.  This  would  take  a  con-

The  Transistorized  "Little  Gem" 

A  Versatile  R.F.  and  D.C.  Meter 

BY  E.  LAIRD  CAMPBELL,  WICUT 


THE  high  cost  of  transistors  has  Umited  tran- 
sistor use  in  amateur  radio.  Recently,  how- 
ever, low-cost  transistors  have  been  made 
available,  and  we  can  expect  to  see  them  in  fre- 
quent use.  Since  the  transistor  is  very  small,  light 
in  weight,  rugged  and  easily  powered  by  a  small 
pen-light  cell,  its  logical  application  is  to  portable 
equipment.  The  above  advantages  obviously  add 
up  to  the  transistor's  application  to  portable 
measuring  devices  for  the  ham.  The  instrument 
described  here  can  be  used  in  five  different  ways: 
field-strength  meter,  wavemeter,  microammeter, 
milliammeter,  and  'phone  quality  monitor.  It  is  a 
"natural"  for  mobile  work  as  it  can  be  carried 
about  without  restricting  wires  or  bulky  batteries. 
The  transistor  in  this  unit  operates  as  a  current 
amplifier  to  multiply  the  input  signal  to  a  value 
high  enough  to  be  indicated  on  a  0-1  milliam- 
meter. This  allows  a  less  expensive  and  more 
rugged  milliammeter  to  be  used  instead  of  the 
usual  expensive  microammeter. 

The  diagram  of  Fig.  1  shows  the  circuit  of  the 
instrument.  When  used  as  a  field-strength  meter 
or  a  wavemeter,  the  signal  from  the  source  to  be 
measured  is  received  by  the  antenna  and  tuned 
by  LiCi.  It  is  then  rectified  by  the  crystal  diode 
and  impressed  on  the  transistor  where  it  is  ampli- 
fied and  indicated  on  the  meter.  Since  the 
transistor  inherently  has  a  static  collector  current 
under  no-signal  conditions,  some  means  must  be 
provided  to  electrically  balance  or  zero  the  meter. 
This  is  accomphshed  by  adjusting  the  variable 


•  Almost  10  years  ago  (January,  1946) 
QST  carried  a  description  of  the  "Little 
Gem,"  an  absorption-type  wavemeter 
that  doubled  as  'phone  monitor  and 
field-strength  indicator.  By  adding  the 
gain  of  a  transistor  d.c.  amplifier  stage, 
the  sensitivity  of  the  gadget  is  increased 
considerably,  and  what  is  normally  a 
milliammeter  becomes  a  microammeter. 
This  Mill  be  found  to  be  a  handy  and 
useful  instrument  to  have  around  the 
shack.  Once  you  have  used  it  you  will 
see  why  it  is  called  the  "Little  Gem." 


resistance,  Ri.  If  the  signal  being  measured  is 
very  strong,  no  external  antenna  will  be  necessary 
for  full-scale  deflection.  When  more  sensitivity 
is  needed,  a  short  piece  of  stiff  wire  can  be  con- 
nected to  the  antenna  binding  post. 

If  it  is  desired  to  check  the  quality  of  a  'phone 
signal,  it  is  only  necessary  to  plug  a  pair  of  head- 
phones into  the  'phone  jack.  The  closed-circuit 
jack  isolates  the  meter  from  the  circuit  and  al- 
lows the  amplified  audio  component  of  the  recti- 
fied signal  to  be  heard. 

When  the  instrument  is  to  be  used  as  a  micro- 
ammeter, the  transistor  is  switched  from  the 
diode  rectifier  circuit  to  polarized  pin  jacks 
mounted  on  the  cabinet.  The  transistor  continues 
to  operate  as  a  current  amplifier,  and  full-scale 
deflection  can  be  obtained  with  a  very  small  cur-

of  the  meter  is  0-1  ma.,  switching  is  provided  to 
isolate  the  meter  for  milliampere  readings.  The 
two  pin  jacks  used  for  microampere  readings  are 
also  used  for  measuring  milliamperes. 

Construction 

The  imit  is  constructed  in  a  4  X  2  X  4-inch 
utility  cabinet.  Placement  of  the  components  is 
not  critical  for  operation,  but  some  care  must  be 
exercised  because  of  space  considerations.  The 
meter  and  the  tuning  control,  C\,  are  mounted  on 
the  removable  front  plate.  Since  the  meter  is 
mounted  at  the  very  top  of  the  face  place,  some 
of  the  lip  on  the  box  will  have  to  be  removed  to 
allow  the  meter  to  fit  properly.  Function  switch, 
zero  adjust  control  and  pin  jacks  are  all  mounted 
on  one  end  of  the  box,  with  the  coil  socket  and 
antenna  post  on  the  other.  The  'phone  jack  and 
holding  handle  are  secured  to  opposite  sides  of  the 
box.  The  handle  on  this  unit  was  placed  for  a 
left-handed  person  but  it  can  be  mounted  on 
either  side.  The  transistor  is  supported  by  its  own 
leads,  and  great  care  must  be  exercised  in  solder- 
ing because  an  excess  of  heat  will  permanently 
impair  its  operation.  It  is  good  practice  to  hold

transistor  can  be  seen  at  bottom  center  supported  by  its 
own  leads.  The  pen-light  cell  is  supported  by  soldering

Operation 

To  use  the  instrument  as  a 
field-strength  meter  or  micro- 
ammeter,  the  function  switch 
is  turned  to  the  desired  posi- 
tion and  the  meter  is  balanced

control  until  the  pointer  is  set  on  zero.  The  meter 
is  now  ready  for  use  and  no  further  adjustments 
are  necessary.  To  measure  the  strength  of  a  signal, 
the  tuning  control  is  turned  until  the  maximum 
reading  is  found.  Once  the  tuning  control  is  set, 
relative  strength  measurements  can  be  made  for 
different  antenna  conditions.  A  calibration  chart

807s  in  Parallel 

75-  to  150'Watt  Amplifier  with  Pi-Section  Output 

BY  FRANCIS  M.   YANCEY,*  K4CDO 


THE  amplifier  shown  in  the  photographs  was 
designed  to  cover  all  bands  from  3.5  to  30 
Mc.  It  can  be  operated  at  an  input  of  150 
watts  on  C.W.,  or  120  watts  on  'phone.  However,  it 
will  operate  efficiently  at  75  watts  input  for 
Novice  use. 

Circuit 

A  pair  of  807s  in  parallel  is  shown  in  the  circuit 
diagram  of  Fig.  1.  A  pair  of  lG25s  may  be  substi- 
tuted if  a  12.6-volt  filament  transformer  is 
provided. 

The  amplifier  is  capacitively  coupled  to  the 
driver  through  the  lOO-ix/jii.  mica  capacitor,  Ci. 
(If  the  driver  includes  an  output  coupling  ca- 
pacitor, Ci  may  be  omitted,  of  course.)  Li  and  Lo 
are  small  inductors  which,  in  conjunction  with 
7?2  and  R3  in  the  screen  leads,  are  used  for  the 
suppression  of  v.h.f.  parasitics. 

A  combination  of  battery  and  grid-leak  bias  is 
used.  Since  the  screens  are  operated  from  a  low- 
voltage  source,  the  fixed  bias  provided  by  the 
battery  will  cut  the  input  to  the  807s  to  zero  when 
excitation  is  removed,  as  in  ke3dng  preceding 
stages  for  c.w.  operation.  When  the  screens  are 
supplied  through  a  dropping  resistor  from  the

plate  supply,  as  required  for  plate-screen  modula- 
tion, the  battery  will  hold  the  input  to  a  safe  level 
in  case  of  excitation  failure,  although  the  input 
will  not  be  reduced  to  zero. 

A  pi-section  tank  circuit  is  used  in  the  output, 
and  parallel  plate  feed  is  therefore  necessary. 
Either  a  rotary  inductor  from  a  surplus  BC-375-E 
antenna-tuning  unit  or  a  Johnson  type  229-201 
inductor  may  be  used  as  the  variable  inductor, 
Li.  L3  is  a  separate  inductor  for  10-meter  opera- 
tion. It  will  not  be  needed  if  the  Johnson  inductor 
is  used,  or  if  the  surplus  inductor  is  used  and  IO- 
meter operation  is  not  required. 

The  required  output  capacitance  is  furnished 
by  a  combination  of  a  variable  capacitor,  C5, 
and  several  fixed  capacitors  that  may  be  switched 
in  parallel  with  the  variable.  A  total  of  about 
2000  nnL  should  be  provided.  For  a  continuous 
range  of  capacitance,  each  of  the  fixed  capacitors

capacitors  and  switch  in  the  corner.  The  variable  input  capacitor  is  to  the  right  of  the  variable  inductor.  The  r.f. 
choke  and  by-pass  fastened  to  the  rear  wall  of  the  chassis  are  in  the  plate  circuit.  The  biasing  battery  can  be  seen  in 
the  compartment  to  the  right  which  also  houses  the  input-circuit  components.  L3  and  Cr,  were  not  used  in  this  unit.

maximum  capacitance  of  the  variable.  As  an 
example,  a  500-^l^f.  variable  and  three  500-At/uf. 
fixed  capacitors  may  be  used.  A  250-MMf-  variable, 
on  the  other  hand,  will  require  seven  2oO-MMf-

them. 

RFC2  removes  the  d.c.  plate  voltage  from 
across  the  input  and  output  tuning  capacitors,

former is  provided  with  a  3-ampere  fuse,  the 
supply  will  be  prot(>ct(>d.

this  case,  the  caj^acitor  can  be  series-resonated  to 
the  particular  channel  by  adjusting  its  lead  length 
(represented  by  L5).  It  should  be  connected  di- 
rectly across  the  output  coax  connector.

Plate  and  grid  milliammeters  are  not  included 
in  the  unit,  but  are  mounted  externally  on  an- 
other panc'l  to  keep  them  out  of  r.f.  fields.  J2 
is  provided  for  plugging  in  a  cord  from  the  grid 
milliammeter  while  checking  grid  cvu'rent.  The 
plate  m(>ter  is  wired  in  permanently  through 
terminals  at  the  rear  of  the  chassis.  If  desired, 
the  jack  can  be  omitted  and  the  grid  milliammeter

An  inverted  10  X  17  X  4-inch  aluminimi

are  drilled  in  the  cover  and  along  the  lips  of  the 
chassis  so  that  the  cover  may  be  secured  tightly 
to  the  chassis  with  Xo.  G  self-tapijing  screws.  The

pins  are  joined  by  the  two  resistors  Ro  and  R^  in 
series.  RFCi  is  a  National  R-IOO-S,  or  similar 
model,  with  an  insulating  mounting.  It  is  placed 
centrally  between  the  two  sockets  and  between 
the  partition  and  the  end  of  the  chassis.  It  is 
eventually  fastened  against  the  bottom  of  the 
chassis.  However,  until  the  assembly  is  ready  to 
be  fastened  in  place,  it  is  suspended  by  its  leads. 
The  two  parasitic  suppressor  chokes,  Li  and  L2, 
are  connected  between  the  No.  2  i)ins  on  the 
sockets  and  the  top  of  RFC\.  If  C\  is  used,  it 
should  be  connected  between  the  top  of  the  r.f. 
choke  and  the  excitation  input  connector,  J\. 
Otherwise,  a  short  piece  of  wire  should  be  substi- 
tuted. The  grid  leak,  Ri,  is  mounted  between  the 


bottom  end  of  RFC\  and  an  insulated  tie  point, 
and  the  grid  by-pass,  €%  is  connected  between 
the  botom  end  of  the  choke  and  a  ground  on  the 
partition.  The  negative  terminal  of  the  biasing 
battery  is  also  connected  to  this  tie  point,  while 
the  positive  terminal  goes  to  J2- 

Three  shielded  and  by-passed  leads  are  pre- 
pared as  described  in  the  TVI  chapter  of  the 
ARRL  Handbook.  One  lead  is  connected  to  the 
junction  of  i?2  and  R-^.  The  other  two  leads  are 
fastened  to  the  No.  1  pins  of  the  sockets.  After 
the  partition  has  been  fastened  in  place,  the  lead 
from  the  junction  of  the  resistors  should  be  con- 
nected to  the  screen-voltage  input  terminal.  The 
other  two  leads  both  are  run  together  to  the  un- 
grounded heater  input  terminal.  The  shields  of 
these  three  leads  are  grounded  at  both  ends,  to 
each  other,  and  to  the  chassis  at  several  points. 

The  plate  blocking  capacitor,  C3,  is  mounted 
with  one  of  its  terminals  central  in  respect  to 
the  two  807  plate  caps  to  permit  plate  leads  of 
equal  length.  The  parallel-feed  plate  choke, 
RFCz,  is  mounted  off  the  rear  wall  of  the  chassis, 
with  its  cold  end  close  to  the  high-voltage  in- 
put terminal.  The  plate  by-pass,  C7,  is  fastened 
against  the  rear  wall  of  the  chassis,  and  is  con- 
nected between  the  cold  end  of  the  r.f.  choke  and 
the  high-voltage  input  terminal  with  the  shortest 
possible  leads. 

The  variable  inductor  cannot  be  mounted 
centrally  in  the  chassis  without  interfering  with 
the  removal  of  the  807s.  It  is  placed  an  inch  or  so 
away  from  the  plate  caps  of  the  tubes,  and  the 
input  and  variable  output  capacitors  are  spaced 
symmetrically  on  either  side.  The  fixed  capacitors 
in  parallel  with  C5  are  stacked  up  and  fastened 
to  a  grounding  bracket  attached  to  the  left- 
hand  end  of  the  chassis.  The  front  terminals  of 
these  capacitors  are  connected  to  the  terminals 
of  *Si  mounted  immediatelj'  in  front. 

Adjustment 

The  values  of  input  and  output  capacitance 
and  the  value  of  the  inductance  to  be  used  in  the 
pi  network  will  depend  upon  the  voltage  and  cur- 
rent at  which  the  amplifier  is  operated.  For  full 
input  on  c.w.,  a  voltage  of  750  at  200  ma.  is 
required  for  the  plates,  and  250  volts  at  12  ma. 
for  the  screen  grids.  In  this  case,  screen  voltage  is 
best  obtained  from  the  exciter  plate  supply.  For 
full  input  on  'phone,  a  supply  delivering  600  volts 
at  200  ma.  is  needed,  and  275  volts  at  13  ma.  for 
the  screens.  For  'phone  work,  the  screen  voltage 
should  be  taken  from  the  plate  supply  through  a 
25,000-ohm  20-watt  resistor. 

For  Novice  operation,  the  amplifier  can  be 
operated,  for  instance,  at  500  volts,  150  ma. 
with  both  tubes  in  use,  or  at  750  volts,  100  ma. 
with  one  of  the  tubes  removed. 

An  accompanying  table  shows  the  values  of 
input  and  output  capacitance  and  the  inductance 
required  for  a  tank-circuit  Q  of  12  and  5()-ohm 
output  under  the  four  operating  conditions 
described  above.  The  Johnson  inductor  does  not 
have  sufficient  inductance  for  a  Q  of  12  under

Power  and  Meter  Facts  in  S.S.B.  Operation 

Interpreting  the  Linear- Amplifier  Plate  Meter  Reading 
BY  HOWARD  F.  WRIGHT,  JR.,*  WIPNB 


•  Here  is  some  down-to-carth  talk  about 
linear  amplifiers,  power  ratings  and 
meter  readings  that  is  "must"  reading 
for  all  s.s.b.  enthusiasts.  WII'NIJ  pre- 
sents the  case  in  simple,  nontechnical 
language  and  with  illustrations  that 
clearly  demonstrate  the  basic  principles. 


DID  you  ever  see  an  cartiole  mainly  concerning 
tlie  plate  meters  of  final  r.f.  ami)lifiers?  For 
that  matter,  have  you  ever  given  the  sub- 
ject much  thought?  Well,  if  not,  it's  certain  that 
you  have  never  used  a  linear  amiJifier  in  single- 
sideband  suppressed-carrier  operation.  Of  course, 
if  you  are  a  person  with  al)solutely  no  aspirations 
toward  s.s.b.  in  the  future,  you  might  be  excused 
for  saying,  "Who  cares.^"  However,  the  way 
things  are  progressing  on  the  "Donald  Duck" 
front,  I  think  there  are  many  who  will  be  inter- 
ested in  the  following  material. 

Why  all  the  fuss  al)out  meters?  In  the  days  of 
regular  a.m.  there  wasn't  much  concern.  The  d.c. 
plate  meter  gave  most  of  the  answers  without 
complaint.  Watch  the  meter.  Tune  up  the  rig. 
Figure  the  power  input  —  no  strain,  no  pain! 
What  could  be  neater?  To  say  that  this  no  longer 
holds  true  with  a  linear  amplifier  in  suppressed- 
carrier  service  would  be  quite  an  understatement. 
Strong  men  have  wej^t  bitter  tears  and  spent 
sleepless  nights  because  of  the  behavior  (or  mis- 
behavior) of  their  linear's  plate  meter.  Why? 
Simply  because  most  of  us  seem  to  find  it  ex- 
tremely difficult  to  modify  our  nearly  complete, 
all-abiding  faith  in  the  value  of  the  plate  meter  in 
indicating  final  amplifier  performance. 

Let's  get  down  to  brass  tacks.  The  attitude  of 
an  amateur  toward  the  plate  meter  of  his  linear 
final,  under  voice  conditions,  is  of  great  impor- 
tance. It  could,  from  a  broad  point  of  view,  mean 
complete  success  or  partial  failure  of  amateur 
narrow-band  communication  techniques. 

Why  does  the  d.c.  plate  milliammeter  fall  down 
so  badly  in  indicating  the  performance  of  ampli- 
fiers in  s.s.b.  voice  service?  It's  because  the  meter 
is  no  longer  able  to  settle  at  a  steady  value  as  it 
did  in  the  amplification  of  unvarying  carrier  sig- 
nals. The  voice  modulation  consists  of  sporadic 
bursts  of  energy.  They  say,  "The  hand  is  faster 
than  the  eye."  If  so,  the  voice  is  certainly  faster 
than  the  meter.  The  meter  just  doesn't  move 
rapidly  enough.  It  starts  to  follow  the  first  voice 
impulse  up,  but  moves  so  slowly  that  it  meets  the 
signal  coming  down.  Then  it  tries  to  follow  down-

ward.  In  this  it  also  fails.  If  a  constant  sound  is 
used  instead  of  words,  the  meter  stabilizes  at  an 
"average"  value.  When  the  signal  varies  with  the 
syllables  of  speech,  the  meter  bobbles  around. 
The  amount  of  movement  depends  upon  many 
factors.  Meters  can  have  differing  time  constants 
(speeds  of  response).  Different  voices  contain 
varying  amounts  of  "average"  power.  The 
amount  of  swing  depends,  to  some  degree,  upon 
the  class  of  amplifier  operation:  ABj,  AB2,  or  B. 

Distortion 

A  "linear"  must  amplify  the  signal  from  its 
exciter  without  changing  the  waveshape  of  the 
original  signal.  Any  change  of  waveshape  is  dis- 
tortion. Distortion  means  that  new  signals  are 
generated.  These  new  signals  result  in  splatter. 
Serious  sjilatter  needs  no  comment. 

Every  linear  amplifier  has  an  amplitude  point 
at  which  it  will  produce  no  further  luidistorted 
output.  Although  the  driving  signal  continues  to 
increase,  the  output  no  longer  increases  in  exact 
proportion.  While  any  change  of  the  signal  wave- 
shape at  levels  other  than  this  maximum  value 
also  causes  some  trouble,  it  is  most  imperative 
that  the  "limiting"  or  "flattening"  point  not  be 
exceeded. 

I  have  previously  indicated  that  the  plate 
meter  is  basically  incapable  of  indicating  the 
peaks  of  a  voice  signal.  Any  relationship  between 
voice  excursions  of  the  plate  meter,  as  it  measures 
d.c.  power  input,  and  undistorted  unflattened 
amplifier  output  is  apt  to  be  purely  coincidental. 

We  now  have  both  elements  of  a  conflict.  On 
one  hand  there  are  the  years  of  reliance  upon  the 
plate  meter  in  indicating  amplifier  performance, 
and  on  the  other  the  meter's  basic  inability  to 
show  lack  of  linearity.  If  the  meter  is  such  a  poor 
performer,  why  do  we  continue  to  use  it?  Simply 
because,  when  properly  interpreted,  the  meter  is 
still  a  valuable  gadget.  It  just  needs  a  bit  of 
understanding. 

Meter  vs.  'Scope 

Articles  concerning  linear-amplifier  adjustment 
make  adequately  clear  the  fact  that  the  oscillo- 
scope is  the  best  tool  for  indicating  performance. 
Whether  the  use  of  this  valuable  instrument  is 
any  more  vital  to  the  adjustment  of  a  s.s.b.  trans- 
mitter than  it  is  to  making  a  conventional  a.m. 
'phone  station  work  properly  might  be  a  matter 
for  debate.  While  a  gratifying  number  of  amateurs 
are  now  using  'scopes,  it  would  be  unrealistic  to 
think  that  all  s.s.b.  stations  will  ever  be  moni- 
tored at  all  times  by  operators  using  such  instru- 
ments. In  fact,  an  operator  who  understands  what 
his  plate  meter  means,  in  conjunction  with  some

of  a  comparison  between 
the  plate  milliammeter 
reading  and  the  output

shows  a  different  type  of 
signal  input,  actual  am- 
plifier adjustment  remains 
unchanged  in  all  cases. 
The  purpose  of  the  com-

the  action  of  the  average- 
reading  meter  as  compared 
to  the  instantaneous-read-

signals  of  varying  wave- 
shapes.

form  of  output  indication,  can  do  quite  well  with 
no  'scope. 

Each  of  the  accompanying  photographs  shows 
a  different  condition  of  amplifier  operation  or 
type  of  signal  input  as  seen  on  both  a  'scope  and 
the  d.c.  plate  milliammeter.  The  purpose  is  to 
demonstrate  the  action  of  the  average-readnig 
meter  as  compared  to  the  instantaneous-reading 
'scope.  Both  continuous  signals  and  voice  are 
used. 

Fig.  1  shows  a  two-tone  test  signal.  This  type 
of  signal  is  used  to  determine  linearity  and  lack 
of  distortion  on  all  parts  of  the  waveshape.  At 
this  time,  notice  only  one  thing.  The  top  of  the 
pattern  remains  unflattened  and  fills  up  the  space 
between  the  limit  lines.  No  splatter  caused  by 
distortion  of  peaks  occurs  as  long  as  we  do  not 
try  to  exceed  the  limits  while  using  this  set  of 
amplifier  conditions.  This  holds  true  in  all  the 
following  pictures  regardless  of  the  type  of  signal 
input. 

Fig.  2  shows  the  amplifier  being  driven  into 
distortion  on  the  two-tone  signal.  The  peak  linear- 
Fig.  1  —  The  "two-tone"  linearity  test  signal  which 
was  used  to  adjiist  the  amplifier  for  low  distortion  over 
all  parts  of  the  waveshape.  At  this  time,  notice  only  one 
thing:  the  top  of  the  pattern  remains  "unflattened"  or 
"unsquashed."  It  extends  exactly  from  one  horizontal 
line  on  the  oscillogram  to  the  other.  These  lines  repre- 
sent the  point  of  peak  linearity  capahility  of  the  ampli- 
fier. No  splatter  caused  hy  "limiting"  of  peaks  can  occur 
as  long  as  we  do  not  try  to  drive  any  type  of  signal  past 
the  amplitude  point  represented  hy  the  lines.  This  holds 
true  in  all  of  the  pictures. 

Fig,  2  —  The  amplifier  driven  into  heavy  distortion 
on  the  same  test  signal.  The  linearity  capability  has  been 
exceeded.  Note  the  "squashing"  of  peaks.  Now  compare 
the  meter  reading  to  that  of  Fig.  1.  The  meter  shows 
what  we  all  like  to  see  —  more  power  input;  but  the 
'scope  indicates  this  is  distorted  power. 

Fig.  3  —  The  result  of  inserting  a  steady  audio  tone 
into  a  s.s.b.  exciter.  It  may  not  look  like  sine-wave  radio, 
but  that  is  because  we  no  longer  have  an  audio  signal. 
The  exciter  converted  the  single  tone  audio  into  single 
frequency  r.f.,  the  same  as  an  unmodulated  carrier.  (The 
slight  ripple  represents  imperfect  sideband  and  carrier 
suppression  and  harmonic  audio  distortion.)  Look  at  the 
meter!  On  steady  signal  the  amplifier  has  no  time  to  rest. 
It  works  regularly  —  not  in  spurts  —  as  on  voice.  The 
meter  has  a  chance  to  indicate  maximum  signal  input. 

Fig.  4  —  Actual  voice  waveshapes.  A  sustained  note 
was  used  for  clarity  of  presentation.  Notice  that  the 
high-amplitude  low-energy  peaks  which  are  encountered 
in  the  voice  just  reach  the  lines  representing  maximum 
permissible  amplitude.  Look  at  the  meter.  Oh,  how  sad! 
That  is  the  current  we  must  use  to  figure  power  input. 


Fig.  5  —  The  audio  gain  increased  to  give  a  more 
satisfying  meter  reading.  Yes,  the  meter  reads  more,  but 
look  at  the  'scope.  Those  peaks  are  really  flattening. 
Splatter!  Zounds!  No  escape!  A  clean  signal  dictates  low 
meter  reading,  while  greater  deflection  causes  trouble. 

Fz'g.  6  —  Another  voice  sound,  purposely  altered  by- 
audio  compression  to  increase  the  "average-to-peak' 
ratio.  Notice  that  the  meter  again  shows  an  increase 
over  the  conditions  of  Fig.  4.  This  is  also  due  to  "flat- 
tening" of  the  waveshape.  Distortion  of  the  audio  signal 
is  again  present,  as  it  was  in  Fig.  5,  but  no  splatter  is 
transmitted  if  the  resulting  new  frequencies  are  carefully 
filtered  out  early  in  the  exciter.  New  frequencies,  caused 
by  r.f.  amphfier  flattening,  cannot  be  removed.  They 
will  he  transmitted  to  plague  adjoining  channels. 


ity  capal)ility  has  been  exceeded.  Note  the  flat- 
tening of  the  peaks.  Now  notice  the  meter  reading 
as  compared  to  Fig.  L  The  meter  shows  what  we 
all  like  to  see  —  more  power  —  but  the  'scope 
indicates  that  it  is  distorted  power. 

Fig.  3  shows  the  result  of  introducing  a  single 
audio  tone  into  the  speech  amplifier.  It  may  not 
look  like  sine-wave  audio,  but  this  is  because  we 
no  longer  have  an  audio  signal.  The  s.s.b.  exciter 
converted  the  single  tone  audio  into  single  fre- 
quency r.f.  —  practically  the  same  as  an  unmodu- 
lated carrier.  Look  at  the  plate  meter!  On  steady 
signal  the  amplifier  has  no  time  to  rest.  It  works 
regularly  —  not  in  spurts  as  on  voice.  The  meter 
has  a  chance  to  indicate  full  maximum  signal 
input. 

Fig.  4  shows  an  actual  voice  waveshape.  The 
sound  used  was  a  sustained  "0-o-o-h-h-h."  No- 
tice that  the  "peaks"  just  reach  the  limit  lines. 
Look  at  the  meter.  Oh,  how  sad!  That's  the  cur- 
rent we  must  use  to  calculate  power  input! 

Fig.  5  is  the  (-ondition  where  the  audio  "gain" 
is  increased  to  conect  the  low  meter  reading.  Yes, 
the  meter  reads  more,  but  take  a  look  at  the 
'scope.  Those  peaks  are  really  flattening.  Splatter! 
Zounds!  No  escape!  A  clean  signal  means  lower 
meter  reading,  while  greater  deflection  causes 
trouble. 

P'ig.  6  shows  the  same  voice  sound,  purposely 
altered  by  audio  compression,  to  increase  the 
"average-to-peak"  ratio.  Notice  that  the  meter 
again  shows  an  increase  over  the  conditions  of 
Fig.  4.  This  is  also  due  to  the  flattening  of  the 
waveshai)e.  Distortion  of  the  audio  is  present,  but 
no  splatter  results  if  the  new  frequencies  are  care- 
fully filtered  out  early  in  the  exciter.  New  fre- 
quenc-ies  resulting  from  r.f.  linear  amplifier  flat- 
tening cannot  be  filtered  out.  They  will  be  trans- 
mitted to  plague  adjoining  channels. 

Study  of  the  photographs  reveals  that  there  is, 
as  previously-  mentioned,  lack  of  connection  be- 
tween d.c.  meter  readings  and  the  type  and  qual- 
ity of  actual  amplifier  output. 

The  situation  looks  rather  gloomy,  doesn't  it? 
Is  it  possible  for  an  average  amateur  to  operate 
a  linear  amplifier  properly  without  access  to 
laboratory  measuring  technitiues:-'  Well,  the  best 
answer  I  can  give  is  that  hundreds  are  doing  it 
every  day.  Perhaps  the  meters  don't  give  all  the 
necessary  indication,  but  never  underestimate  the 
flexibility  of  an  amateur.  The  trial-and-error  sys- 
tem can  do  wonders. 

Splatter 

A  chain  of  two  or  more  linear  amplifiers,  upon 
construction,  is  hardly  ever  able  to  develop  maxi- 
mum rated  output  without  considerable  adjust- 
ment. Luckily,  s.s.b.  transmitting  and  receivhig 
techniques  have  the  valuable  property  of  making 
nonlinear  amplifier  distortion  and  splatter  stick 
out  like  a  sore  thuml).  While  the  same  amount  of 
distortion  would  be  partly  hidden  by  the  voice 
sidebands  of  a  double  sideband  signal  and  be 
somewhat  obscured  by  lack  of  selectivity  in  an 
ordinary  receiver,  such  is  not  the  case  on  s.s.b. 
There  is  no  such  thing  as  distortion  splatter  which

appears  on  only  one  side  of  the  carrier  frequency. 
A  s.s.b.  receiver  has  an  opportunity  to  view, 
generally  unhindered  l)y  readable  signal  from  the 
s.s.b.  exciter,  the  amplitude,  nature  and  fre- 
quency spread  of  nonlinear  amplifier  splatter  ap- 
pearing on  the  unwanted  sideband.  This  situation 
makes  possible  accurate  and  worth-while  on  the 
air  reports  of  amplifier  performance.  In  cases  of 
"peak  limiting"  distortion,  one  can  simply  turn 
down  the  gain  until  the  person  at  the  receiv- 
ing end  reports  a  clean  "unwanted"  sideband. 
Changes  can  then  be  made  to  try  and  allow  more 
power  without  degrading  the  signal. 

Power  Input 

Now  what  about  power  input.'  Ask  a  s.s.b. 
operator  exactly  how  much  power  he  is  running. 
The  answer  might  sound  something  like,  "Well, 
the  plate  voltage  is  2000  and  the  meter  kicks  up 
to  about  200  mils  on  voice  peaks.  That's  about 
400  watts.  Of  course,  that's  only  meter  reading. 
Actually,  the  peak  power  is  a  lot  more  than  that." 

Now  really  pin  him  down.  Ask  him  what  his 
"peak"  power  really  is.  For  that  matter,  what 
does  he  mean  by  "peak  power"?  Chances  are, 
his  eyes  might  take  on  a  rather  furtive  look.  He 
might  mention  something  about  multiplying  the 
meter  reading  by  the  factor  1.57.  Don't  press  him 
too  far.  You  might  become  as  confused  as  he  is.

Actualh',  the  power-input  situation  is  not 
nearly  as  complicated  as  it  is  confused.  The  in- 
discriminate use  of  the  word  "peak"  to  describe 
three  distinctly  different  conditions  is  detrimental 
to  the  clarity  of  the  otherwise  fairly  simple  mat- 
ter of  power-input  considerations. 

The  three  uses  of  "peak,"  as  heard  on  the  air 
and  seen  in  print,  are  "instantaneous  peak 
power,"  "peak  envelope  power,"  and  "meter 
peak,  on  voice,  power."  Unfortunately,  it  has 
seemed  fashionable  to  omit  the  ciualifying  terms 
and  call  any  one  of  them  "peak  power."  When 
this  happens,  even  a  person  who  understands  the 
situation  perfectly  must  determine  which  yard- 
stick is  being  used  l)efore  giving  intelligent  con- 
sideration to  the  particular  situation  involved. 

There  are  two  ways  which  I  could  use  to  ex- 
plain the  different  kinds  of  "peak  power."  One 
would  be  to  draw  a  rather  involved  illustration  of 
a  modulated  r.f.  signal,  showing  both  individual 
r.f.  cycles  and  cycles  of  modulating  voltage.  The 
other,  which  I  shall  try,  is  to  explain  the  same 
effects  in  a  non-radio  exami)le  which  closely  paral- 
lels the  case  of  modulated  r.f.  energy. 

Our  example  is  to  be  a  "four-way"  reading 
lamp,  one  that  plugs  into  the  110-volt  a.c.  socket 
and  allows  the  user  to  select  various  conditions 
of  brightness.  One  setting  is  "off"  —  the  others

range  from  "dim"  to  full  intensity  of  the  100- 
watt  bulb.  Now  let's  imagine  that  this  light  bulb 
represents  the  r.f.  output  signal  of  a  s.s.b.  trans- 
mitter, not  in  the  usual  sense  of  a  "dummy  load," 
but  with  the  more  abstract  view  that  each  cycle 
of  60-cycle  a.c.  current  represents  a  similar  cycle 
of  high-frequency  energy  in  the  r.f.  signal.  Thus 
the  lamp,  burning  steadily  at  full  brilliance,  repre- 
sents a  s.s.b.  amplifier  with  full  "inserted  carrier" 
of  100  watts.  Now,  still  in  the  abstract  vein,  the 
brightness  control  switch  of  the  four-way  lamp 
will  be  used  to  represent  modulation.  The  switch 
is  made  to  vary  the  brilliance  of  the  lamp  at  a 
fairly  slow  and  sporadic  rate  from  one  intensity 
to  another.  This  simulates  voice  modulation.  The 
remaining  item  in  our  flight  of  fancy  is  something 
to  represent  the  plate  milliammeter  in  the  trans- 
mitter. Let's  say  that  we  connect  an  a.c.  ammeter, 
with  a  very  sluggish  movement,  in  series  with  the 
a.c.  cord  to  the  lamp.  This  simulates  the  inability 
of  a  plate  meter  accurately  to  follow  voice  modu- 
lation. We  are  now  ready  to  demonstrate  the 
meaning  of  "instantaneous  peak,"  "peak  en- 
velope or  maximum  signal,"  and  "meter  peak, 
on  voice"  power. 

To  find  "instantaneous  peak  power,"  we  turn 
our  100-watt  light  to  full  brilliance.  For  sim- 
plicity, let's  say  that  the  r.m.s.  voltage  is  100 
instead  of  110.  Ohms  Law  says  that  the  r.m.s. 
current  is  1  ampere.  Consider  only  one  cycle  of 
the  60-cycle  wave.  The  "crest  or  instantaneous 
peak"  voltage  in  this  cycle  is  1.41  times  100  volts. 
This  is  141  volts.  The  current  at  "peak"  is  1.41 
amperes.  If  P  =  IE,  the  concept  of  "instantane- 
ous peak  power"  says  that  200  watts  of  power 
exist  for  an  infinitely  small  period  of  time  at  the 
crest  of  the  cycle.  What  does  this  mean  from  the 
point  of  view  of  a  man  reading  a  book?  Nothing! 
He's  got  a  lamp  that  gives  a  hundred  watts  of 
illumination  and  he  knows  it.  The  same  holds 
true  in  a  radio  transmitter.  "Instantaneous  peak 
power"  has  very  little  value  in  everyday  opera- 
tion and  adjustment. 

Now  to  the  heart  of  the  matter  —  "peak  en- 
velope power"  or  "maximum  signal  power."  This 
is  possibly  the  most  useful  of  our  terms.  It  is  the 
way  tube  manufacturers  rate  their  product.  More 
often  than  not,  it  is  meant  when  one  sees  "peak" 
mentioned  in  print.  What  is  the  value  in  the  case 
of  our  light  bulb  example?  —  100  watts:  it's  as 
simple  as  that!  Just  a  minute!  How  can  the  100 
watts  be  "peak  power"  and  still  be  the  value 
determined  by  multiplying  average  r.m.s.  voltage 
times  r.m.s.  current  (100  volts  times  1  ampere)? 
This  certainly  gives  "average"  and  not  "peak" 
power.  In  this  case,  the  word  "peak"  no  longer 


24 


QST  for 


refers  to  the  crest  of  the  60-cycle  wave.  To  show 
what  is  meant,  we  no  longer  run  the  lamp  at  full 
power,  but  simulate  modulation  by  varying  the 
average  power  all  the  way  from  zero  to  maximum. 
Now  the  light  bulb  (or  amplifier)  doesn't  work 
fully  all  the  time.  It  has  comparative  periods  of 
rest  because  the  signal  is  pulsating  at  a  sporadic 
rate.  In  this  case  "peak"  refers  to  the  fact  that 
the  full  100  watts  average  power  only  exists  for  a 
relatively  short  period  of  time.  So  short,  in  fact, 
that  the  sluggish  a.c.  meter  in  the  line  would 
never  have  a  chance  to  indicate  an  amount  of 
average  power  approaching  the  100  watts  we 
know  briefly  exists. 

The  obvious  solution  to  determining  "maxi- 
mum 'average'  signal  power"  is  to  switch  the 
lamp  to  full  brilliance  and  leave  it  there  while  the 
meters  catch  up.  The  same  holds  true  with  a  s.s.b. 
transmitter.  Never  measure  "peak  envc^lope  or 
maximum  signal  power"  under  voice  conditions. 
Insert  carrier  or  whistle  into  the  microjjhone  and 
the  meters  will  accurately  record  this  kind  of 
"peak"  power.  From  a  strictly  r.f.  point  of  view, 
we  are  still  dealing  with  "average  power"  values. 
These  should  be  familiar  to  all  of  us. 

"Meter  peak,  on  voice,  power"  is  fairly  self- 
explanatory.  I  have  said  that  the  a.c.  meter  in  our 
lamp  cord  was  far  too  sluggish  to  follow  even  the 
relatively  slow  variations  of  power  which  repre- 
sented modulation.  It  has  already  been  explained 
why  power  figiu-es  derived  from  fluctuating  d.c. 
meters  arc  nearly  useless  as  an  indication  of  am- 
plifier performance  unless  correlated  with  other 
measurements.  I  mention  this  type  of  power  again 
onlj'  to  show  the  need  for  learning  what  kind  of 
"peak  power"  is  being  used  whenever  the  sul)ject 
arises  in  a  discussion  of  linear  amplifi(>rs. 

Perhaps  unfortunately,  from  one  point  of  view, 
the  regulations  recjuire  that  s.s.b.  transmitter 
power  be  determined  from  meter  swings  on  voice. 
This  has  the  effect  of  keeping  the  prt'ssure  on  an 
amateur  to  achieve  more  meter  swing.  That's 
fine,  if  it  isn't  done  at  the  expense  of  linearity. 
This  measuring  system  leads  to  an  interesting 
situation.  If  one  has  an  amjilifier  that  "talks  up" 
to  a  kilowatt,  he  wouldn't  be  able  to  whistle  into 
the  microphone  without  exce(>ding  the  legal  limit. 
However,  the  "maximum  signal  power"  would  be 
the  same  in  both  cases. 

Earlier  I  mentioned  the  figure  1.57  in  connec- 
tion with  "peak"  power.  Never  use  it  unless  you 
are  dealing  with  "two- tone"  tests.  What  is  a 
"two-tone"  test.^  Just  because  a  s.s.b.  exciter  is 
generalh'  used  as  a  source  of  signal  for  this  linear- 
ity test  doesn't  mean  that  it  is  a  complicated 
situation.  Actually,  two  ordinary  r.f.  oscillators, 
separated  in  freciuency  by  several  hundred  cycles 
and  simultaneously  feeding  equal  signals  into  a 
linear  amplifier  chain,  would  work  equally  well. 
I  won't  go  into  the  reason  why  two  steady  fre- 
quencies, rather  than  one,  are  used  to  show  dis- 
tortion. However,  one  thing  may  seem  strange. 
The  average  amplifier  power,  as  read  by  the 
meter,  is  much  less  with  two  signals  than  it  is 
with  one.  Due  to  the  coml)ination  of  the  signals, 
the  amplifier  no  longer  works  all  the  time.  It  has 


periods  of  rest.  The  "maximum  signal  power" 
remains  at  full  value,  but  the  "average-reading" 
meter  indicates  far  less  current.  If  the  amplifier  is 
Class  B,  the  meter  now  only  reads  about  6-4  per 
cent  of  its  value  for  one  signal  of  the  same  maxi- 
mum amplitude.  The  reciprocal  of  .64  is  1.57. 
Thus  the  meter  reads  1.57  times  as  much  on  a 


^\\     ptatoDs  Of  n£sx ' 


single  signal  (such  as  carrier )  as  it  does  on  a  "  two- 
tone"  test.  This  factor  only  applies  to  Class  B 
operation.  Class  AB2  and  Class  ABi  have  re- 
spectively lower  ratios  of  difference  in  meter  read- 
ings between  signals  of  one  and  two  frequencies. 
Continuing  in  the  same  direction,  Class  A  entails 
a  ratio  of  imity  because  there  ran  be  no  change 
of  plate  current,  regardless  of  the  type  or  number 
of  signals. 

From  the  above,  one  can  see  that  the  figure 
1.57  should  only  be  used  in  one  specialized  case, 
never  when  referring  to  voice  defiection  of  a 
meter.  A  person  can't  look  at  a  dancing  plate 
meter  and  accurately  see  that  his  "maximum  sig- 
nal or  peak  envelope  power"  is  a  certain  given 
amount.  As  a  final  check  to  i)rove  that  the  factor 
1.57  actually  works  out  in  practice,  refer  back  to 
the  photographs  and  compare  the  currents  in 
Figs.  1  and  3. 

Adjustment  Without  a  'Scope 

This  isn't  basically  an  article  on  linear-amplifier 
adjustment,  but  I  am  going  to  give  an  example 
to  demonstrate  the  proper  use  of  d.c.  meters  when 
nothing  better  is  available.  The  procedure  falls 
into  the  "cheap  and  dirty,  but  rather  effective" 
class. 

Before  I  proceed  I  point  out  that  throughout 
this  article  I  have  mentioned  only  the  "final 
amplifier."  Actually,  flattening  and  distortion 
may  occur  in  any  driver  stage.  I  do  not  think  it 
necessary,  for  our  purposes,  to  stress  meter  read- 
ings and  waveshapes  for  other  stages.  The  indica- 
tions occurring  at  the  output  of  the  final  accu- 
rately reflect  the  condition  of  earlier  stages.  Of 
course,  in  actual  practice  it  is  necessary  to  locate 
and  work  on  the  weak  link. 

Let's  saj^  that  I  have  an  amplifier  whose  specs 
call  for  a  plate  voltage  of  1500  and  ma.ximum 
signal  current  of  300  ma.  (Remember,  the  manu- 
facturer means  on  a  single  steady  signal,  not 
voice.)  First,  I  insert  some  carrier  from  the  ex- 
citer. I  tune  the  grid  and  plate  circuits  to  reso- 
nance as  indicated  by  an  output  indicator.  (Any 
type  of  output  indicator  connected  to  the  feedline

One  Tube -80  and  40  Meters -75  Watts 

Using  the  6146  as  a  Crystal  Oscillator 

BY  LEWIS  G.  McCOY,  WIICP 


YES,  the  title  is  correct.  This  article  describes 
a  one-tube,  two-band,  crystal-controlled 
oscillator  capable  of  running  approximately 
75  watts  input.  By  utilizing  a  single  tube  as  a 
high-power  oscillator,  the  circuitr>-,  wiring,  and 
construction  are  kept  as  simple  as  possible.  In 
addition,  by  making  use  of  the  "economy" 
power  supply,^  watts-per-dollar  is  held  at  a 
maximum.  Another  feature  of  the  rig  is  that 
when  the  Novice  graduates  to  the  General  Class 
ranks,  the  components  can  all  be  used  in  an  all- 
band  rig. 

Circuit  Details 

The  "economy"  power  supply  uses  an  ordi- 
nary' replacement-t^'pe  transformer  in  a  bridge 
circuit.  As  can  be  seen  from  the  circuit  diagram. 
Fig  1,  the  transformer  rating  is  350  volts  each 
side  of  center  tap,  but  the  output  voltage  ob- 
tained is  approximately  500.  The  supply  \\'ill 
deUver  500  volts  at  140  ma.,  which  is  adequate 
for  the  one-tube  transmitter.  For  time-up  pur- 
poses, the  output  of  the  power  supply  can  be 
switched  from  high  to  low  voltage.  The  low 
potential  output  is  280  volts. 

In  order  to  limit  the  input  to  75  watts,  the 
screen  voltage  is  held  to  125  volts  by  /2ii?2-  With 
the  supply  output  switched  to  low  voltage,  the 
screen  drops  to  80  volts,  convenient  for  tune-up 
purposes. 

The  crystal  current  is  monitored  by  a  2-volt 
GO-ma.  bulb  connected  between  the  crystal  and 
chassis  ground.  The  bulb  also  serves  as  a  fuse,  in 
the  event  the  crystal  current  should  accidentall}' 
rise  above  a  safe  value. 

To  avoid  coil  changing,  a  portion  of  the  plate

mighty  hard  to  beat.  At  catalog  prices

Co  Ji  struc  tion 

The  transmitter  is  built  on  an  11X7X3- 
inch  aluminum  chassis  and  the  6146  and  r.f. 
components  above  deck  are  shielded  by  a  6  X 
6  X  6-inch  aluminum  box.  If  one  lives  in  an 
area  where  there  is  no  danger  of  TVI,  the  tube 
and  other  parts  above  chassis  could  be  left  un- 
shielded. The  controls  could  be  mounted  on  a 
panel.  However,  because  TVI  must  be  considered, 
the  construction  shown  here  takes  care  of  the 
bugaboo. 

The  transformer  and  rectifiers  are  mounted  on 
the  chassis  top  at  one  end.  The  other  power  sui> 
plj'  components;  T\,  Li,  the  S-^f.  electrolytic 
capacitors  and  the  20,000-ohm  10-watt  resistors, 
are  moiuited  below  deck. 

The  (5146  socket  is  mounted  l}4  inches  in  from 
the  front  of  the  chassis  and  4J^  inches  from  the 
end.  Two  1-inch  isolantite  standoffs  are  used  to 
support  L2L3,  and  they  are  mounted  2}4  inches 
apart.  The  rear  one  is  2}/^  inches  from  the  chassis 
back  and  2  inches  from  the  side. 

A  row  of  34-inch  holes  is  drilled  near  the  bot- 
tom on  both  sides  of  the  cover  box  to  permit

taps  of  jf'i  and  tlu;  high-voltage  winding  of  T^ 
are  connected  together  and  soldered  to  the  low-

wonder  why  the  two  8-/if.  electrolytic  capacitors 
are  connected  in  series.  This  is  to  double  the

likely  to  run  higher  than  desired.  No  socket 
should  be  used  for  the  2-volt  GO-ma.  dial  lamp  in 
series  with  the  crystal.  A  5^-inch  rubber  grommet 
is  used  to  hold  the  dial  lamp  in  place.  The  inside 
diameter  of  the  grommet  is  ^g  inch,  just  large 
enough  to  accommodate  the  glass  envelope  of  the 
lamp.  Connections  are  made  to  the  lamp  by 
soldering  leads  to  the  base  point  and  to  the  metal 
shell.  The  lead  from  the  shell  connects  to  the 
chassis. 

Standard  coil  stock  (B  &  W  3900,  2-inch  diam., 
8  turns  per  inch.  No.  14  wire)  is  used  for  L2L3.  A 
total  of  38  turns  is  cut  from  the  original  stock.  At 
one  end  of  the  piece,  a  single  turn  is  unwound 
from  the  support  bars.  From  this  end,  count  up 
7}4  turns  and  cut  the  seventh  turn.  The  cut 
should  be  made  at  the  support  bar  opposite  the 
bar  from  which  the  first  lead  extends.  The  leads 
from  the  cut  point  are  separated  from  the  side 
support  bars  and  brought  around  to  the  same  bar 
as  the  first  lead.  At  the  other  end  of  the  coil, 
which  will  be  the  top,  a  lead  is  unwound  from 
the  support  bars  and  extends  from  the  bar  oppo- 
site the  one  with  the  three  leads.  This  coil  is 
showii  in  one  of  the  photographs. 

Counting  from  the  top,  the  15th  and  17th 
turns  are  bent  in,  allomng  access  to  the  16th  turn. 
This  is  for  the  40-meter  tap.  A  four-inch  length  of 
wire  can  be  soldered  to  this  point.  The  other  end 
will  connect  to  the  switch  terminal  on  .S'4. 

The  coil  is  supported  on  the  isolantite  standoffs 
by  two  soldering  lugs.  The  small  ends  of  the  lugs 
are  first  bent  around  the  bottom  turn.  Before 
soldering  them  in  place,  the  large  holes  in  the 
lugs  should  be  located  over  the  holes  in  the  stand- 
offs for  proper  alignment. 

A  coax  receptacle  is  mounted  on  the  back  of 
the  shield  box  and  positioned  so  that  the  terminal 
is  opposite  the  ungi-ounded  end  of  link  L3.  The 
switch  and  capacitor  can  be  mounted  in  the  box 
first  and  then  wired.  However,  it  will  probably  be 
easier  for  the  beginner  to  wire  all  the  components 
first,  and  then  mount  them  in  the  box.  Three 
holes  are  needed  in  the  front  of  the  shield  box. 
The  capacitor  and  switch  holes  are  1}^  inches  in 
from  the  side  of  the  box  and  2}4,  and  4}  9  inches

from  the  bottom,  respectively.  The  hole  for  the 
5^-inch  grommet  is  2  inches  to  the  left  of  the 
capacitor  hole.  With  the  holes  cut  in  the  box,  it  is 
easy  to  fit  the  box  over  the  wired  parts. 

When  mounting  the  glass  bulb  of  the  plate 
circuit  6-volt  dial  lamp  in  its  grommet,  be  careful 
that  none  of  the  metal  parts  of  the  bulb  base  come 
in  contact  with  the  metal  of  the  box.  If  the  bulb 
shorted  to  chassis  ground,  the  power  supply 
might  be  damaged.  If  the  builder  desires,  a  200- 
or  250-ma.  milliammeter  can  be  substituted  for 
the  bulb. 

It  was  found  in  initial  tests  with  the  unit  de- 
scribed here  that  a  bad  v.h.f.  parasitic  was  pres- 
ent. This  was  eliminated  by  using  an  Ohmite 
Z-144  choke  in  series  with  the  plate  lead  at  the 
plate  of  the  tube. 

Testing  the  Transmitter 

After  the  unit  is  wired  it  is  ready  for  testing.

Portable  Antennas  for  50  and  144  Mc. 

Come-Apart  Arrays  for  Use  Away  from  the  Home  Station 
BY  EDWARD  P.  TILTON,  WIHDQ 


•  Mobile  operation  on  6  or  2  is  great 
stuff,  but  if  you  like  to  work  from  the 
mountain  tops,  or  in  other  choice  v.h.f. 
spots,  you'll  soon  come  to  the  conclusion 
that  you  need  something  better  in  the 
way  of  an  antenna  system  than  a  vertical 
whip.  Here  are  portable  beams  for  50  and 
144  Mc.  that  can  be  packed  in  the  back 
of  your  car  and  still  leave  room  for  the 
lunch.  They  can  be  put  up  in  your  fav- 
orite location  in  a  matter  of  minutes. 


EVEN  if  you  live  at  the  busiest  iutorseotion  or 
in  the  lowest  sjjot  in  town,  you  can  still  have 
fun  on  the  v.h.f.  hands.  Pack  up  >our  gear 
and  antennas  and  head  for  the  wide  open  spaces. 
Our  spring  and  fall  V.H.F.  QS(^  Parties  and  the 
Annual  ARRL  P^ield  Day  provide  week  ends  of 
concentrated  v.h.f.  operating,  and  a  family  picnic 
at  any  other  time  can  be  combined  with  an  ex- 
pedition to  some  choice  v.h.f.  sjjot. 

This  calls  for  antennas  that  can  be  erected  and 
dismantled  easily.  The  arrays  for  50  and  144  Mc. 
shown  here  can  be  stowed  in  the  back  of  almost 
any  car,  even  with  only  partial  dismantling.  The 
quick  method  leaves  the  2-meter  antemia  assem- 
bled, and  merely  involves  removing  extensions 
from  the  G-meter  elements.  In  this  form  the  an- 
tennas and  supporting  mast  can  be  assembled, 
ready  for  use  in  your  favorite  v.h.f.  location  in 
less  than  five  minutes.  If  you  require  a  smaller 
package,  removing  a  few  screws  and  folding  the 
2-meter  elements  permits  packing  the  works  in  a 
space  five  feet  long  and  aboiit  six  inches  sciuare. 
From  this  stage  to  on-the-air  might  take  a  matter 
of  10  minutes,  at  the  most. 

The  Iwams  are  not  intended  to  be  world-beaters. 
The  real  v.h.f.  exjiedition  enthusiast  will  want 
something  better,  but  these  antennas  do  surpris- 
ingly well  in  a  good  location.  The  6-meter  arra,y 
has  a  driven  element  and  director,  both  3-piece 
elements.  The  2-nieter  job  is  a  cut-down  TV  array 
originally  made  for  Channel  6.  Its  elements  fold 
back  against  the  boom,  if  necessary.  Both  an- 
tennas use  gamma-match  feed  for  either  52-  or 
75-ohm  coaxial  line. 

A  Quick-Up  Support 

A  convenient  support  can  l)e  made  from  1 }  2- 
inch  aluminum  TV  masting.  Two  10-foot  lengths 
were  purchased  and  cut  in  half.  One  5-foot  piece 
was  cut  for  the  6-meter  boom  and  the  other 
three  are  our  mast.  The  bottom  section  is  fastened 
to  the  door  handle  with  a  sheet  aluminum  clamp 
similar  to  those  described  for  assembling  all- 
metal  v.h.f.  arrays  shown  in  all  recent  editions  of 


the  Handbook.  No  dimensions  are  given  here,  as 
requirements  are  likely  to  be  different  for  other 
makes  of  cars.  A  sample  clamp  can  be  made  of 
stiff  paper  or  from  flashing  copper,  and  this  used 
as  a  template  for  making  the  real  thing  out  of 
3  .32-inch  sheet  aluminvnii. 

In  the  photograph  only  two  mast  sections  are 
shown  in  use,  but  in  many  locations  the  full  15 
feet  may  be  desiral)le,  particularly  if  there  are  low 
obstructions  in  the  immediate  vicinity  of  the  car. 
Checks  in  wide-open  spots  have  shown  that  there 
is  not  a  great  difference  between  the  10-  and  15- 
foot  heights  otherwise.  There  is  more  variation 
in  driven-element  impedance  at  the  lower  height 
as  the  anteima  is  rotated,  but  performance  is  not 
seriously  affected. 

To  provide  a  stable  support  without  guying, 
the  l)Ottom  of  the  mast  must  be  anchored  thor- 
oughly. We  usually  rvm  an  old  screwdriver  into 
the  ground  and  slip  the  mast  over  it.  If  the  car  is 
parked  on  a  hard  surface,  the  mast  can  be  held 
firm  by  j)lacing  some  large  rocks  around  the  base. 

A  helpful  feature,  added  to  the  mast  after  the 
photograph  was  made,  is  a  34-inch  bolt  6  inches 
long,  run  through  the  second  mast  section.  A 
piece  of  the  half-inch  element  stock  \]/i  inches 
long  is  slipiKHl  over  the  bolt  when  it  is  inserted, 
leaving  a  quarter  inch  for  tightening  the  nut  on 


The  portable  6-  and  2 -meter  arrays  ready  for  use. 
They  are  shown  here  on  a  10-foot  support,  but  another 
5-foot  section  can  be  added  without  need  for  guying.

the  other  side  of  the  tubing.  The  telescoping  por- 
tions of  the  masting  are  6  inches  long.  If  this  bolt 
is  run  through  the  outer  tubing  exactly  G  inches 
from  the  end  it  will  provide  a  bearing  for  support- 
ing the  weight  of  the  antenna,  as  well  as  serving 
as  a  turning  handle  and  direction  indicator.  The

driven  element.  The  series  capacitor  and  the  coaxial 
fitting  are  mounted  on  a  small  U-shaped  bracket.  If  the 
elements  are  to  be  removed  from  the  boom  for  carrj  ing, 
the  screw  and  nut  holding  the  connection  to  the  match- 
ing section  can  be  removed.  The  mounting  clamps  must 
also  be  removed  from  the  center  section  of  each  element 
in  this  case.  Ordinarily,  the  boom  and  two  center  sec- 
tions are  left  assembled  for  carrying  in  the  car. 

latter  assumes  that  the  bolt  is  lined  up  with  the 
booms  of  the  antennas.  The  "direction  indicator" 
is  no  gag.  Looking  up  at  the  beam  elements  after 
dark  is  likelj-  to  be  rather  confusing. 

Beam  Details 

The  6-meter  arraj'  was  held  to  two  elements  for 
light  weight  and  compact  design.  Even  this  sim- 
ple antenna  will  be  a  great  improvement  over 
anything  in  the  way  of  a  strictly  mobile  set-up. 
Hilltop  checks  with  horizontally  polarized  fixed 
stations  indicate  an  average  gain  of  25  to  30  db. 
over  the  quarter-wave  whip  normally  used  for 
mobile  work.  If  the  fixed  stations  were  vertically 
polarized  the  story  would  be  quite  clifTerent,  liut 
as  practically  all  6-meter  work  is  done  with  hori- 
zontal beams  today,  the  portatile  array  enjoys  a 
tremendous  advantage  over  a  vertical  whip. 

Construction  follows  the  all-metal  technique 
outlined  in  the  v.h.f.  antenna  chapter  of  all  recent 
editions  of  the  Handbook.  The  boom,  made  from 
the  leftover  piece  of  masting,  is  86  inches  long. 
The  director  and  driven  element  are  34  inches 
apart.  They  pass  through  the  Ijoom  and  are  held 
in  place  by  semicircular  clamps  of  sheet  alumi- 
num. There  must  be  solid  contact  between  the 
boom  and  elements,  otherwise  reception  will  be 
nois}-  when  the  elements  flutter  in  the  wind. 

We  used  half-inch  dural  tubing,  but  the  size  is 
not  critical.  Anything  up  to  one  inch  can  be  run 
through  13^-inch  tubing.  The  center  sections  of 
both  elements  are  363^  inches  long.  Two  more 
363^-inch  sections  are  added  to  the  driven  ele- 
ment, while  the  director  extensions  are  34  inches. 
An  alternative  method  would  be  to  make  the 
center  section  of  the  director  31 3^  inches  long,  in 
which  case  the  extensions  would  all  be  the  same 
length  and  interchangeable. 


Inserts  about  four  inches  long,  for  taking  the 
extensions,  were  turned  down  from  aluminum 
rod.  If  a  lathe  is  not  available  for  this  work,  the 
extensions  can  be  attached  by  the  sleeve  method 
outlined  in  all  recent  Handbooks.  Pieces  of  the 
element  tubing  about  6  inches  long  are  sawed 
lengthwise,  taking  out  enough  of  the  material  so 
that  the  i-emainder  can  be  compressed  to  make  a 
tight  fit  inside  the  tubing.  These  are  inserted  into 
both  ends  of  the  center  sections  to  a  depth  of 
three  inches,  leaving  three-inch  exposed  portions 
onto  which  the  extensions  are  slipped.  The  abra- 
sive nature  of  aluminum  tends  to  make  the  parts 
hold  together  tightly  enough  for  the  purpose, 
without  fastenings,  even  after  considerable  use. 
The  writer  has  used  the  compressed-sleeve  method 
in  portable  antennas  for  years,  and  found  it  quite 
adequate  for  the  purpose.  It  is  most  satisfactory 
with  elements  of  ^-inch  or  larger  diameters, 
when  the  beam  is  for  50  Mc.  or  lower  frequencies. 
Smaller  diameters  and  thin-wall  tubing  are  satis- 
factory for  144  Mc.  or  higher. 

The  6-meter  boom  is  held  to  the  support  by 
the  familiar  aluminum  clamp.  Again,  as  tubing 
sizes  may  vary,  no  dimensions  are  given.  Suitable 
dimensions  are  arrived  at  most  readily  by  the 
template  method  already  outlined.  The  clamp 
assembly  is  held  together  with  No.  8  machine 
screws,  the  ends  of  which  were  swaged  in  a  vise 
after  the  nuts  were  run  on  part  way.  Two  of  the 
four  screws  required  for  the  door-handle  clamp 
can  be  swaged  in  this  wa^',  also,  leaving  only  two 
nuts  that  must  be  removed  in  taking  the  assembly 
apart  for  ordinary  carrying.  If  the  arrays  are  to 
be  completely  dismantled,  removal  of  six  more 
screws  will  do  the  job. 

The  simplest  way  to  make  a  2-meter  antenna 
is  to  cut  down  a  Channel  6  TV  Yagi.  The  one  we 
used  was  originally  a  5-element  jol:)  having  a 
folded-dipole  radiator.  The  boom  was  too  long  to 
fit  in  the  back  of  our  car,  so  it  was  cut  down  to  a 
4-element  antenna.  The  spare  director  element 
was  then  made  into  a  gamma-matched  dipole, 
which  was  installed  in  place  of  the  folded  dipole 
originally  used  for  the  driven  element.  Many  TV 
Yagis  are  supplied  with  elements  that  fold  back 
against  the  boom,  a  mechanical  arrangement  that 
is  ideal  for  portable  use.  Spacing  of  the  elements 
is  not  particularly  critical.  The  Channel  6  spac- 
ings  may  be  used  for  144  Mc,  also,  though  the 
arra>'  can  be  revamped  to  Handbook  dimensions  if 
3'ou  like. 

Element  lengths  were  cut  to  Handbook  dimen- 
sions. As  has  been  done  many  times  before,  we 
experimented  a  bit  with  adjustable  elements  and 
came  to  the  conclusion  that  there  was  little  to  be 
gained  from  attempting  to  tune  up  the  system, 
except  for  the  matching  adjustments,  which  will 
be  detailed  later.  The  length  of  the  driven  element 
in  inches  is  found  by  dividing  the  number  5540 
by  the  frequen(!y  in  megacycles.  The  reflector  is 
5  per  cent  longer,  the  first  director  5  per  cent 
shorter,  and  the  forward  director  6  per  cent 
shorter  than  the  driven  element.  This  applies  to 
both  the  50-  and  144-Mc.  arrays.  Final  dimen- 
sions we  used  were  as  follows:  Driven  element  —

QST  for 


38  inches;  reflector  —  40  inches;  first  director  — 
36  inches;  forward  director  —  35 M  inches.  This 
gives  fairly  uniform  j^crformance  from  144  to  146 
Mc.  Both  gain  and  front-to-back  ratio  fall  off 
slightly,  but  not  seriouslj-,  above  the  middle  of 
the  band. 

Adjustment 

Details  of  the  gamma  matching  systems  are 
shown  in  close-up  photographs.  A  section  of  tub- 
ing or  rod  similar  in  size  to  the  diiven  element  is 
mounted  on  om^  side  of  the  element  and  parallel 
to  it  with  small  cone  stand-off  insulators.  An 
adjustable  aluminum  clamp  makes  contact  be- 
tween the  matching  section  and  the  main  cle- 
ment, the  point  of  coimection  being  moved  until 
the  Ix'st  possible  imijcdance  match  is  achieved. 
A  series  tuning  capacitor  is  coiuiected  between 
the  matching  section  and  the  inner  conductor  of 
the  coaxial  line,  to  tune  out  the  reactance  of  the 
matching  section. 

The  gamma  section  is  12  inches  long  on  the 
50-Mc.  array  and  6  inches  on  th(>  144-Mc.  one. 
A  series  capacitor  of  50  nfii.  will  do  for  either 
array.  The  spacing  of  the  capacitor  may  be  small, 
as  the  r.f.  voltage  is  very  low  at  this  point.  Iwen 
the  smallest  available  capacitor,  the  Hammar- 
lund  type  MAPC-50,  is  suitable  for  the  low 
power  generally  used  in  portable  work.  If  you're 
worried  about  the  effects  of  moisture,  a  piec(>  of 
plastic  film  may  be  wrapped  around  the  tuning 
capacitors  when  the  arrays  are  used  in  rain\- 
weather. 

There  is  only  one  way  to  adjust  a  matching 
system  and  be  sure  that  you're;  doing  it  properly, 
and  that  is  with  a  standing- wave  l)ridge.  The 
point  of  connection  l)etween  t\w  gamma  section 
and  the  driven  element  should  be  set  at  about  4 
inches  for  the  2-metei'  antenna  or  10  inches  for  the 
6-meter  one.  The  series  trimmer  capacitor  is  then 
adjusted  for  minimum  reflected  power.  If  the 
indication  will  not  drop  to  zero  or  v(;ry  close  to 
it,  try  moving  the  connecting  clip,  retuning  the 
series  capacitor  for  each  new  setting  of  the  cli|). 
Be  sure  that  the  clip  is  making  a  clean  tight  ct)n- 
tact  on  each  test  jjosition,  or  it  will  be  impossil)le 
to  obtain  a  good  match.  Good  contact  in  the 
coaxial  cable  connectors  is  also  extremely  im- 
portant. We  had  plenty  of  trouble  in  the  initial 
stages  of  the  projec^t  as  the  result  of  the  outer 
conductor  of  our  coax  making  poor  contact  to  the 
connector  sleeve. 

A  rough  approximation  of  the  correct  setting 
can  be  made  by  adjusting  the  gamma  match  and 
series  capacitor  for  maximum  field-strength  indi- 
cation, but  the  field-strength  metin-  methofl  is  the 
hard  way.  The  lowest  possible  s.w.r.  may  not  be 
too  important,  with  the  short  run  of  coax  used  in 
a  portable  setup  ordinarily,  but  the  bridge  method 
is  so  simple  and  exact  that  it  should  be  used 
wherever  possible. 

Some  Random  Ideas 

Portable  antenna  design  is  a  fruitfid  field  for 
the  gadgeteer,  and  there  are  countless  ways  the 
job  can  be  done.  Perhaps  you  want  to  use  the 


folded-dipole  feed  s>'stem  that  came  on  the  TV 
antenna  originally.  All  right,  just  use  a  coaxial 
balun  and  72-ohm  coaxial  line.  If  the  TV  antenna 
was  designed  for  300-ohm  feed,  the  balun  will  give 
you  a  good  match. 

I\Ia>'be  you'd  like  to  stack  two  antennas  for 
144  Mc.  In  that  case,  if  each  array  has  folded- 
dipole  feed  tlesigned  foi-  300-ohm  line,  space  the 
two  arrays  80  inches  apart  and  feed  through  a 
balun  at  the  midpoint  of  the  open-wire  phasing 
line.  The  balun  and  transmission  line  should  be 
of  50-ohm  coax  in  this  case.  This  will  not  provide 
a  perfect  match,  but  it  will  be  close  enough  for 
the  purpose.  If  you  want  a  better  match,  connect 
a  shorted  quarter-wave  stub  at  the  feed  point  and 
then  slide  the  balun  up  on  this  stub  for  lowest 
s.w.r. 

F'or  more  gain  on  50  Mc,  add  more  elements, 
following  Handhook  dimensions  forelement  lengths 
and  spacings.  The  gamma  match  arrangement 
will  work  well  with  any  number  of  ekuiients. 

Your  car  bulges  below  the  door  handles?  There 
are  many  other  wa>'S  to  anchor  the  support. 
WlDXK  and  WlV'LH  use  their  bumper  jack, 
tying  the  vertical  supi)ort  to  the  jack  with  web- 
l)ing  straps.  This  puts  rotation  of  the  array  out

tage of  leaving  all  doors  free. 

You  want  to  work  10  meters  too?  The  6-meter

Details  of  the  2-metcr  gamma  match.  The  series 
capacitor  is  mounted  at  right  angles  to  the  boom  in 
this  case,  as  adjustment  is  done  from  the  side  of  the 
array  instead  of  the  end.  Elements  can  he  folded  hack 
against  tlie  boom  if  the  array  must  be  packed  away  in  a 
small  space.

sections,  so  that  all  four  extensions  can  be  plugged 
together  to  make  a  dipole  16  feet  long.  Make  the 
gamma  section  longer,  in  this  case,  to  permit  ad-

Or  take  any  of  these  ideas  and  add  some  more 
of  your  own.  The  point  is  that  operating  v.h.f. 
gear  away  from  your  home  location  in  some  high 
clear  spot  far  from  city  noises  is  lots  of  fun.  If 
you  have  a  top-notch  home-station  setup,  the 
chances  ai'e  that  you'll  never  work  as  far  with  the 
portal:)le  gear  as  you  can  from  home,  but  there's 
something  about  portatjle  operation  that  gets  into 
one's  blood,  even  so.  Try  it,  and  see!

The  Automobile  Storage  Battery 
and  Its  Charging  System 

Principles  and  Limitations  of  Car  Power  Plants 
BY  DONALD  MIX,  WITS 


•  The  success  of  any  mobile  installation 
depends  to  a  large  extent  upon  intelli- 
gent use  and  maintenance  of  the  car's 
storage  battery  and  charging  system.  In- 
cluded in  this  article  is  a  discussion  of 
the  principles  of  charging-regulator 
circuits. 


ELECTRICAL  power  for  motor  cranking  and  for 
operating  lights  and  accessories  in  a  car 
when  the  motor  is  idle  is  furnished  by  a 
storage  battery.  Unlike  a  dry  battery,  which 
must  be  replaced  when  it  is  discharged,  the 
storage  battery  ma.y  be  recharged  hundreds  of 
times  before  its  useful  life  is  ended.  The  charging 
is  done  automatically  when  the  engine  is  running 
by  means  of  a  generator  belt-driven  from  the 
crankshaft  of  the  motor. 

The  storage  battery  is  made  up  of  units  con- 
sisting of  a  pair  of  coated  lead  plates  immersed 
in  a  solution  of  sulphuric  acid  and  water.  The 
basic  unit  delivers  a  nominal  voltage  of  2.  The 
number  of  watt-hours  (watts  X  hours)  that  may 
be  drawn  from  the  battery  before  recharging  is 
necessary  is  increased  by  enlarging  the  plate  area 
and  by  connecting  units  in  parallel.  Such  an 
assembly  is  called  a  cell.  Cells,  each  of  which  de- 
livers about  2  volts,  can  be  connected  in  series  to 
obtain  the  desired  batterj^  voltage.  A  6-volt  bat- 
tery therefore  has  three  cells,  and  a  12-volt 
battery  has  6  cells.  The  average  stock  car  battery 
has  a  rated  capacity  of  600  to  800  watt-hours, 
regardless  of  whether  it  is  a  6-volt  or  12-volt 
battery.  Special  heavy-duty  batteries  with  larger 
capacities  are  available. 

Specific  Gravity  and  the  Hydrometer 

The  electrical  power  delivered  by  a  storage 
battery  is  a  result  of  chemical  action  between  the 
sulphuric  acid  in  the  solution  (electrolyte)  and 
the  lead  plates.  As  power  is  drawii  from  the  bat- 
tery, the  acid  content  of  the  electrolyte  is  reduced. 
The  acid  content  is  restored  to  the  electrolyte 
(meaning  that  the  battery  is  recharged)  bj^ 
passing  a  current  through  the  battery  in  a  direc- 
tion opposite  to  the  direction  of  the  discharge 
current.  The  positive  terminal  of  the  charger  is 
connected  to  the  positive  terminal  of  the  battery. 
The  positive  terminal  of  the  battery  is  usually 
identified  by  a  +  mark  and  is  of  slightly  greater 
diameter  than  the  negative  terminal. 

Since  the  acid  content  of  the  ele(!trolyte  varies 
with  the  charge  and  discharge  of  the  battery,  it  is 


possible  to  determine  the  state  of  charge  by 
measuring  the  specific  gravity  of  the  electrolyte. 
Specific  gravity  is  the  ratio  of  the  weight  of  a  unit 
volume  of  electrolyte  to  the  weight  of  an  equal 
volume  of  water. 

An  inexpensive  device  for  checking  the  s.g.  is 
the  hydrometer  which  can  be  obtained  at  any 
automobile  suppl.y  store.  The  h,ydrometer  con- 
sists of  a  calibrated  glass  float  within  an  outer 
glass  tube  that  is  fitted  at  one  end  with  a  rubber 
suction  bulb,  and  with  a  rubber  nozzle  at  the 
other.  Each  cell  of  the  battery  has  a  removable 
cap  giving  access  to  the  electrolyte.  In  checking 
the  s.g.,  enough  electroh'te  is  drawn  out  of  the 
cell  and  into  the  hydrometer  so  that  the  cali- 
brated bulb  floats  freely  without  leaning  against 
the  wall  of  the  glass  tube.  The  hydrometer  should 
be  held  in  a  vertical  position  at  eye  level  and  a 
reading  taken  at  the  surface  level  of  the  elec- 
trolyte. 

Care  should  be  taken  in  using  the  hydrometer 
because  the  acid  is  harmful  to  the  skin  and  cloth- 
ing as  well  as  to  battery  terminals  and  metal 
parts  of  the  car.  The  electrolyte  should  be  re- 
turned to  the  cell  after  testing.  Each  cell  should 
be  tested  in  turn.

While  the  readings  will  vary  slightly  with  bat- 
teries of  different  manufacture,  a  reading  of 
1.275  should  indicate  full  charge  or  nearly  full 
charge,  while  a  reading  below  1.150  should  indi- 
cate a  batter.v  that  is  close  to  the  discharge  point. 
More  specific  values  can  be  obtained  from  the 
car  or  batter_\^  dealer. 

These  readings  are  normal  for  an  electrolj^te 
temperature  of  80  degrees  F.  For  extremes  of 
temperature,  0.004  should  be  added  to  the  read- 
ing for  each  10  degrees  of  temperature  above  80 
degrees  above  80,  or  subtracted  for  each  10 
degrees  below  80  degrees.  Some  hydrometers 
have  built-in  thermometers  that  simultaneously 
check  the  temperature  of  the  electrolyte.  The

s.g.  reading  of  all  cells  in  a  battery  should  be 
alike  within  0.025. 

Readings  taken  immediatel.y  after  adding 
water,  or  shortly  after  a  heavy  discharge  period 
will  not  be  reliable,  because  the  electrolyte  will 
not  be  uniform  throughout  the  cell.  The  battery

should  be  allowed  to  stand  for  several  hours  be- 
fore taking  the  reading.  Charging  mil  speed  up 
the  ec}ualizing,  and  some  mixing  can  be  done  by 
using  the  hydrometer  to  withdraw  and  return 
some  of  the  electrol>'te  to  the  cell  several  times. 

A  battery  should  not  be  left  in  a  discharged 
condition  for  any  appreciable  length  of  time. 
This  is  especially  important  in  low  temperatures 
when  there  is  danger  of  the  electrolyte  freezing 
and  ruining  the  battery.  A  batter.y  discharged  to 
an  s.g.  of  1.100  will  start  to  freeze  at  about  20 
degrees  F.,  at  about  5  degrees  when  the  s.g.  is 
1.150  and  at  16  below  when  the  s.g.  is  1.200. 
There  should  be  no  danger  of  freezing  if  the  s.g. 
is  kept  at  1.250  or  higher. 

If  a  battery  has  been  run  down  to  the  point 
where  it  is  nearly  discharged,  it  can  usualh'  be 
fast-charged  at  a  batter\'  station.  Fast-charging 
rates  may  be  as  high  as  80  to  100  amperes  for  a 
6- volt  battery.  Although  a  discharged  or  nearly 
discharged  battery  cannot  be  brought  back  to  full 
charge  by  fast  charging,  it  can  be  brought  back  to 
useful  condition  within  a  short  time.  Any  6-volt 
battery  that  will  accept  a  charge  of  75  amperes  at 
7.75  volts  during  the  first  3  minutes  of  charging, 
or  any  12- volt  battery  that  will  accept  a  charge 
of  40  to  45  amperes  at  15.5  volts,  may  be  safely 
fast^charged  up  to  the  point  where  the  gassing 
becomes  so  e.xcessive  that  electrolyte  is  lost  or  the 
temperature  rises  above  125  degrees.  If  the 
battery  requires  more  than  the  above  values  of 


voltage  to  produce  the  currents  specified,  fast- 
charging  should  be  done  with  caution  to  avoid 
excessive  heating. 

A  normal  battery  showing  an  s.g.  of  1.150 
or  less  may  be  fast-charged  for  1  hour.  One 
showing  an  s.g.  of  1.150  to  1.175  may  be  fast- 
charged  for  45  minutes.  If  the  s.g.  is  1.175  to 
1.200,  fast-charging  should  be  limited  to  30 
minutes. 

Care  of  the  Battery 

The  battery  terminals  and  mounting  frame 
should  be  kept  free  from  corrosion.  Any  corrosive 
accumulation  may  be  removed  b}'  the  use  of 
water  to  which  some  household  ammonia  or 
baking  soda  has  been  added,  and  a  stiff-bristle 
brush.  Care  should  be  taken  to  prevent  anj-  of  the 
corrosive  material  from  falling  into  the  cells. 
Cell  caps  should  be  rinsed  out  in  the  same  solution 
to  keep  the  vent  holes  free  from  obstructing  dirt. 

All  connections  to  the  battery  and  along  the 
battery  line  to  the  starter  and  transmitter  should 
be  insjjected  regularl\'  for  loose  or  corroded 
connections.  Battery  terminals  and  their  cable 
clamps  should  be  polished  bright  with  a  wire 
brush,  and  coated  with  mineral  grease.  Solid 
connections  and  adequate  cable  size  in  the  bat- 
ter}'  circuit  are  of  great  importance.  A  150-watt 
load  on  a  6-volt  battery  represents  a  load  re- 
sistance of  only  14  ohm.  If  connection  and  lead 
resistances  amount  to  as  much  as  J4  ohm,  the 
power  d(>liver(>d  to  the  load  will  be  only  one 
fourth  of  that  delivered  with  zero  loss  resistance, 
and  only  half  of  the  power  actually  drawn  from 
the  battery  will  be  dissipated  in  leads  and  con- 
nections. 

The  hold-down  clamps  and  the  batterj'  holder 
should  also  be  checked  occasionally  to  make 
sure  that  they  are  tight  so  that  the  battery  will 
not  be  damaged  by  pounding  when  the  car  is  in 
motion. 

Voltage  Checks 

Although  the  readings  of  s.g.  are  quite  reliable 
as  a  measure  of  the  state  of  charge  of  a  normal 
battery,  the  necessity  for  frequent  use  of  the 
hydrometer  is  an  inconvenience  and  wall  not 
always  serve  as  a  conclusive  check  on  a  defective 
battery.  Cells  may  show  normal  or  almost  normal 
s.g.  and  yet  have  high  internal  resistance  that 
ruins  the  usefulness  of  the  batter\'  under  load. 

When  all  cells  show  satisfactory  s.g.  readings 
and  yet  the  battery  output  is  low,  service  stations 
check  each  cell  by  an  instrument  that  measures 
the  voltage  of  each  cell  under  a  heavy  load.  No- 
load  voltage  measurements  usually  are  meaning- 
less because  it  requires  a  large  current  to  detect 
the  difference  in  internal  resistance  between  a 
normal  cell  and  one  that  is  defective.  Under  a 
heavy  load  the  cell  voltages  should  not  differ  by 
more  than  0.15  volt. 

A  load- volt  age  test  can  also  be  made  by  meas- 
uring the  voltage  of  each  cell  while  closing  the 
starter  switch  with  the  ignition  turned  off.  In 
many  cars  it  is  necessary  to  pull  the  central  dis- 
tributor wire  out  to  prevent  the  motor  starting.

If  the  battery  is  down  so  far  that  it  will  not  turn 
the  cranking  motor,  this  voltage  check  can  still 
be  made.  The  average  cell  of  a  fully-charged 
battery  on  discharge  while  cranking  should 
measure  about  1.95  volts  at  80  degrees,  or  1.4 
volts  at  0  degrees.  A  defective  cell  will  show  up 
quite  readily  by  a  voltage  reading  noticeably 
below  the  readings  of  the  other  cells. 

As  the  normal  battery  ajjproaches  discharge, 
its  internal  resistance  increases  so  that  the  differ- 
ence between  no-load  and  loadc^l  voltages  be- 
comes greater.  A  d.c.  voltmeter  with  a  scale  of 
10  for  a  6-volt  system,  or  25  for  a  12-volt  system, 
mounted  on  the  instrument  panel  and  connected 
to  the  battery  terminals,  may  l)e  used  to  provide 
a  continuous  check  on  the  condition  of  the  l)at- 
tery.  The  most  significant  readings,  of  course, 
will  be  those  made  with  the  transmitter  operating 
and  with  the  car  motor  turned  off.  Experience 
will  show  the  normal  drop  in  battery-terminal 
voltage  to  be  expected  when  the  transmitter 
load  is  turned  on.  Voltage  readings  can  be  co- 
related  with  readings  of  specific  gravity  so  that 
eventually  the  operator  should  be  able  to  estimate 
the  state  of  charge  of  the  battery  with  only  an 
occasional  check  with  the  hydrometer. 

Electrolyte  Level 

Water  is  evaporated  from  the  electrolyte,  but 
the  acid  is  not.  Therefore  water  must  be  added 
to  the  solution  in  each  cell  from  ame  to  time  so 
that  the  plates  are  always  completely  covered. 
Since  the  introduction  of  the  charging  regulator 
several  years  ago,  the  most  frequent  cause  of 
subnormal  battery  life  is  failure  to  maintain 
proper  electrol,yte  level.  The  level  should  be 
checked  at  least  once  per  week,  especially  during 
hot  weather  and  constant  operation. 

Distilled  water  is  preferred  for  replenishing, 
but  (;lear  drinking  water  is  an  acceptable  sul)sti- 
tute.  Too  much  water  should  not  be  added,  since 
the  gassing  that  accompanies  charging  may  force 
electrolyte  out  through  the  vent  holes  in  the  cajjs 
of  the  cells  onto  the  surface  of  the  battery.  The 
electrolyte  expands  with  temperature.  If  a  bat- 
tery is  replenished  when  the  electrolyte  is  at  80 
degrees,  the  level  may  fall  off  as  much  as  ^i  e  inch 
when  the  temperature  drops  to  0  degrees.  Con- 
versely, if  the  electrolyte  is  replenished  at  0 
degrees,  the  cell  may  overflow  at  higher  tem- 
peratures. 

Do  not  use  an  open  flame  when  inspecting  the 
electrolyte  level,  since  the  chemical  action  develops 
hydrogen  gas  which  is  highly  explosive.

Cranking  Power 

It  requires  about  65  per  cent  more  power  to 
crank  a  motor  at  32  degrees  than  at  80  degrees, 
and  aliout  250  per  cent  more  at  0  degrees.  At  the 
same  time,  the  cranking  power  delivered  by  a 
fully-charged  battery  at  32  dt^grees  is  reduced  to 
about  65  per  ccmt  of  that  delivered  at  80  degrees, 
and  to  about  40  per  cent  at  0  degrees.  A  cranking 
motor  will  draw  from  125  to  300  amperes  at  6 
volts  in  summer  and  300  to  700  amperes  in 
winter.

Auxiliary  Charging 

Because  a  car  may  not  be  driven  sufficiently 
to  keep  the  battery  charged,  auxiliary  charg- 
ing from  an  external  source  may  be  required 
from  time  to  time.  Battery  chargers  of  various 
types  are  on  the  market  and  can  be  installed  in 
the  garage  so  that  the  battery  can  be  charged 
during  the  night.  It  is  not  necessary  to  remove 
the  battery  from  the  car.  A  battery  is  fully 
charged  when  the  electrolyte  shows  no  increase  in 
s.g.  over  a  3-hour  period. 

Ba  ttery-  Ch  argin  g  Sys  tern 

In  the  normal  stock  installation,  the  car  battery 
is  charged  by  a  d.c.  generator  driven  by  a  belt 
from  the  motor  crankshaft.  The  output  of  the 
generator  is  governed  by  a  regulator  usually  con- 
sisting of  three  relays. 

The  cutout  relay  is  for  the  purpose  of  discon- 
necting the  generator  from  the  battery  when  the 
generator  is  not  ojjerating,  to  j^revent  the  l)at- 
tery  discharging  through  the  generator  windings. 
The  contacts  of  the  cutout  relay  are  in  series  with 
the  ungrounded  wire  between  the  generator  out- 
put (armature)  terminal  and  the  battery.  When 
the  car  motor  turns  the  generator  over  at  suffi- 
cient S]jeed  to  develop  a  voltage  greater  than  the 
battery  voltage,  the  contacts  close  and  the  gen- 
erator is  connected  to  the  battery.  When  the 
motor  is  slowed  down,  and  the  generator  voltage 
falls  below  the  battery  voltage,  the  contacts 
open,  disconnecting  the  generator  from  the 
battery. 

The  curr-ent-regulator  relay  is  for  the  purpose 
of  protec^ting  the  generator  against  overload.  Its 
contacts  are  connected  across  a  resistor  in  series 
with  the  field  winding  of  the  generator.  When 
the  load  on  the  generator  exceeds  the  (current 
value  to  which  the  regulator  has  l)een  set,  the 
contacts  ojjcn  and  dose,  intermittently  inserting 
th(;  resistor  in  series  with  the  field  winding  at  a 
rate  that  limits  the  average  output  current  to  a 


34 


QST  for 


value  that  is  safe  for  the  generator  to  handle. 
Some  older-model  ears  do  not  have  this  current- 
regulator  unit. 

The  purpose  of  the  voltage-regulator  relaj'  is  to 
assure  adequate  batter\-  charging,  while  prevent- 
ing damage  to  the  battery  from  overcharge.  Its 
contacts  are  also  connected  across  a  resistor  in 
series  with  the  field  winding  of  the  generator. 
\A'hen  properly  adjusted,  it  will  regulate  the 
average  generator  output  voltage  so  as  to  cause 
the  batter}'  charging  current  to  rise  to  a  value 
near  the  maximum  safe  limit  set  by  the  current 
legulator,  and  taper  off  almost  to  zero  current  as 
th(!  l)attery  nears  full  charge.  The  life  of  the  bat- 
tery is  highly  dependent  upon  projjer  adjustment 
of  the  voltage  regulator. 

The  design,  oj^eration  and  adjustment  of 
charging  regulators  vary  appreciably  among  the 
various  makes  and  models.  Proi^er  adjustment 
requires  si)ecial  data,  gauges  and  instruments  not 
often  in  possession  of  anyone  but  (jualified  elec- 
tromotive service  shops.  The  critical  setting  of 
several  spacings  according  to  manufacturer's 
specifications  is  recjuired.  It  is  seldom  a  simple 
matter  of  tightening  or  loosening  the  tension  of  a 
spring.  An  amateur  who  makes  a  mol)ile  installa- 
tion should  ask  the  service  shop  to  check  the 
atljustment  of  the  current  regulator  to  make  sure 
that  it  is  set  for  the  maximum  output  current  for 
which  the  generator  is  rated.  This  will  permit 
maximum  safe  output  from  the  generator  when 
operating  from  the  car  motor,  and  will  allow 
maximum  control  of  the  charging  rat(>  by  the 
voltage  regulator. 

In  general,  there  is  little  to  be  gained  by  a  read- 
justment of  the  voltage  regulator  from  its  origi- 
nal proper  setting,  although  it  would  be  well  to 
have  a  service  chop  check  the  adjustment  peri- 
odicall}'  to  maintain  the  proper  adjustment. 
Voltage-regulator  operation  depends  to  a  large 
extent  upon  the  difference  between  the  battery 
and  generator  voltages  at  any  given  time.  So  long 
as  the  load  current  drawn  does  not  exceed  the 
current  limited  by  the  current  regulator,  the  bat- 
tery voltage  will  be  unaffected,  and  the  voltage 
regulator  will  control  the  battery  charging  cur- 
rent in  the  normal  way.  If,  however,  the  total 
current  drawn  from  the  system  exceeds  the  cur- 
rent for  which  the  current  regulator  is  set,  the  cur- 
rent from  the  generator  will  be  limited  by  the 
current  regulator,  not  by  the  voltage  regulator, 
and  the  extra  current  will  be  drawn  from  the 
battery. 

When  the  external  load  is  removed,  the  voltage 
regulator  will  act  in  normal  fashion,  causing  the 
charging  current  to  rise  to  maximum  until  the 
battery  is  again  near  full  charge.  Setting  the  volt- 
age regulator  to  a  higher  limiting  voltage  will  not 
speed  up  the  recharging,  because  the  charging 
current  is  limited  by  the  current  regulator  to  a 
value  that  is  safe  for  the  generator,  as  men- 
tioned previously.  Increasing  the  limiting  voltage 
of  the  voltage  regulator  will,  however,  result  in 
continued  charging  at  an  excessive  rate  after 
the  battery  has  reached  full  charge,  and  this 
can  cause  reduced  batter}'  life.

Revision  of  6-Volt  Equipment  for 
12-Volt  Operation 


UNFORTUNATELY,  there  is  no  simple  and  in- 
expensive way  of  converting  existing  6-volt 
mobile  installations  for  operation  in  the 
newer  cars  having  12-volt  battery  and  charging 
systems. 

The  simplest  solution  is  provided  by  a  dyna- 
motor  that  has  12-volt  input  and  6-volt  output. 
Such  a  dynamotor  is  produced  by  the  Carter 
Motor  Co.,  and  is  called  the  "Change-a-Volt." 
It  is  rated  at  15  amperes,  6  volts  output  continu- 
ously for  receiver  operation,  and  45  am{)eres  in- 
termittently for  transmitter  use.  The  cost  of  this 
unit,  however,  is  comparable  with  that  of  a  new 
power  unit  for  12-volt  input.  There  is  also,  of

anyone  now  contemplating  an  installation  in  a 
car  with  a  6-volt  system  to  purchase  one  of  the 
dual-input  tj^pes  to  cover  future  use  with  a  12- 
volt  system. 

Filaments 

You  may  be  lucky  enough  to  find  12-volt 
equivalents  for  all  of  the  6-volt  tubes  in  your  in- 
stallation, but  this  will  rarely  be  the  case.  The 
simplest  and  most  efficient  filament  conversion 
consists  of  dividing  the  6-volt  tubes  into  two 
groups  totaling,  as  closely  as  possible,  the  same 
current.  The  two  groups  are  then  connected  in 
series,  as  shown  in  Fig.  1.  If  the  two  branches 
cannot  be  matched  exactly,  a  resistor  should  be 
connected  across  the  branch  of  lesser  current  to 
make  the  total  current  of  this  branch  equal  the 
total  current  of  the  other.  The  value  of  the  re- 
sistor in  ohms  should  be 

6.3 


R  = 

ii  -  l2 

where  I\  is  the  greater  total  current  and  I2  the 
lesser,  in  amperes. 

This  system  can  be  applied  to  any  number  of 
tubes  greater  than  1 .  A  single  tube  will ,  of  course, 
require  a  simple  series  resistor,  as  shown  in  Fig. 
IB.  The  value  of  this  resistor  in  ohms  should  be 


R  = 


6.3 


where  I  is  the  rated  filament  current  of  the  tube 
in  amperes. 

In  this  revision  of  the  filament  wiring,  it  is 
obvious  that  only  one  side  of  one  group  of  fila- 
ments may  be  grounded  to  the  chassis.  One  side  of 
this  group  and  both  sides  of  the  second  group 
must  be  insulated  from  the  chassis.  —  D.H.M.

A  Six-Meter  Club  Project 

Andrews  Electronic  Association  Builds  50-Mc.  Gear 
on  Production-Line  Basis 


BY  JOHN  P.  DRUMMOND,*  W3YHI 


THE  Andrews  Electronics  Assn.,  Andrews  Air 
Force  Base,  Aid.,  recently  took  on  the  con- 
struction of  6-meter  rigs  as  a  club  project. 
As  a  result,  eleven  stations  are  making  their 
50-M(\  debut  near  Washington,  D.  C.  All  but 
one  are  entering  the  v.h.f.  ranks  through  this 
project,  and  more  are  expected  to  follow  shortly. 

This  work  was  undertaken  as  a  result  of  many 
factors.  Members  had  long  agreed  that  a  project 
was  needed  to  stimulate  club  interest.  There  were 
as  many  ideas  as  to  what  its  nature  should  be 
as  there  were  club  members.  Opening  of  the  G- 
meter  band  for  Technician  operation  was  then  in 
prospect.  AEA  had  previously  considered  a  2- 
meter  project  to  provide  improved  local  com- 
munications for  the  club's  "  Windbagger's  Net  " 
))ut  there  was  obvious  need  for  more  activity  on 
50  Mc.  Previous  club  e.xperience  in  sports  car 
races  and  in  ])roviding  communications  of  an 
emergency  nature  had  emphasized  the  need  for 
more  suitable  (>(iuii)ment.  The  v.h.f.  bands  ap- 
peared to  provide  the  best  solution,  but  none 
of  the  equipment  owned  by  the  members  could 
be  used  for  v.h.f.  work.  The  50-Mc.  band  seemed 
like  the  oj)timum  frecjuency,  as  it  would  be  easier 
to  construct  e(iuii)ment  and  better  local  range 
could  be  e.xpected  with  simple  antennas  than  on 
144  Mc.  Then  there  was  the  technical  challenge 
of  potential  TVI  with  fringe-area  reception  of 
Chaimel  2  from  Baltimore.  AEA's  previous 
stand  had  been  in  favor  of  opening  both  2  and 
6  meters  to  Technicians.  Although  AEA  opposed 
the  ARIIL  position  against  opening  144  Mc.  to 
Technicians,  it  accepted  the  League's  decision 
and  was  prepared  to  support  the  will  of  the 
majoi'ity  actively. 

The  usual  problems  were  involved  in  getting 
a  group  to  tackle  a  new  problem.  Again  there 
were  nearly  as  many  ideas  as  members.  Some 
were  not  interested  in  50  Mc;  some  had  no 
construction  experience;  others  had  no  place 
to  work.  A  questionnaire  was  made  up  to  deter- 
mine the  general  characteristics  of  the  equip- 
ment desired  by  the  majority  and  their  willingness 
to  assist  each  other  in  a  cooperative  production- 
line  assembly  project.  The  writer  was  given  the 
task  of  designing  and  building  a  pilot  model  of 
the  transmitter.  The  poll  of  the  members  had 
indicated  that  a  unit  of  15  to  20  watts  input  was 
desired.  It  was  to  be  of  simple  design,  rugged, 
and  inexpensive  to  build,  as  each  member  was  to 
pay  for  his  own. 

The  model  transmitter  was  built  and  a  major 
portion  of  one  meeting  was  devoted  to  an  "on- 

•%  Hq.,  AACS,  AAFB,  Washington,  D.  C. 


the-air"  50-Mc.  session  with  \V30JU,  during 
which  Rick  did  an  excellent  job  of  answering 
questions  thrown  at  him  by  the  AEA  member- 
ship. The  thoroughness  of  W.^OJU's  sales  talk 
was  proven  that  same  night  when  AEA  voted  to 
proceed  without  delay. 

For  economy  reasons,  the  transmittc^r  was 
designed  largely  around  parts  stripped  from 
A\/ARC-4s,  as  we  had  a  source  of  these  units. 
The  final  design  met  the  simplicity  recjuirement. 
It  employed  a  12AT7  overtone  oscillator-doubler 
driving  a  2E26  final  amplifier.  The  modulator 
is  a  pair  of  ()L()S  diiven  directly  from  the  micro- 
phone transformer.  Input  runs  around  20  watts. 
A  list  was  made  of  the  parts  and  tubes  which 
had  to  be  purchased. 

Ten  meml)ers  immediately  indicated  the  desire 
to  build  similar  transmitters  and  they  put  their 
cash  on  the  line  to  prove  it.  The  base  hol)by 


The  finished  product,  a  50-Mc.  transmitter  complete 
with  modulator.  The  r.f.  section  is  similar  to  Handbook 
design,  but  modified  to  make  use  of  available  surplus 
parts.  {USAF photos)

shop  was  selected  as  a  site  for  construction,  and 
one  member  was  nominated  to  purchase  the  parts. 
Special  meetings  were  set  up  for  every  Friday 
night  to  carry  the  construction  through  to  com- 
pletion. The  meeting  then  adjourned  and  the 
committees  swung  into  action. 

Sufficient  ARC-4s  were  rounded  up  to  provide 
the  parts  sources.  The  writer  drafted  a  step-by- 
step  instruction  sheet  for  removal  of  the  parts  to 
be  used,  and  both  were  distributed  among  the 
members  in  advance.  To  the  amazement  of 
those  who  felt  that  the  project  would  not  catch 
on,  more  than  75  per  cent  of  the  membership 
showed  up  the  first  night,  loaded  with  tool 
boxes  and  ready  to  work.  Club  Pre.xy  W3TPT 
staggered  in  bearing  a  large  carton  with  the  pur- 
chased parts  and  announced  that  he'd  cleaned 
the  local  dealers  out.  The  final  cost  per  transmitter 
was  less  than  $10. 

Workers  were  assigned  to  places  in  a  production 
line  headed  by  W3VBE,  who  had  previously 
made  a  template  for  the  chassis.  Hacksaws,  drill 
presses  and  soldering  irons  were  manned  and 
we  were  under  Vt'ixy.  The  chassis  work  (usually 
the  toughest  construction  job)  was  accomplished 
in  a  surprisingly  short  time  as  a  result  of  the  pro- 
duction-line techniques  and  the  availability  of 
wiUing  hands.  All  chassis  were  then  run  back 
down  the  line  for  the  mounting  of  parts  and  pre- 
fabricated assemblies  which  had  been  prepared 
b}^  other  members.  Wiring  was  done  by  following 
simple  step-by-step  instructions  prepared  by  the 
writer  in  the  manner  used  by  the  Heath  Co.  for 
their  kits. 

Although  this  project  is  not  at  this  writing 
fully  completed,  it  has  caused  considerable  com- 
ment in  the  Washington  area.  A  number  of  re- 
quests have  l)een  received  for  information  on  the 
transmitter  design,  method  of  starting  the  proj- 
ect, etc.  Certainly  AEA  can  expect  some  TVI 
cases  to  pop  up,  but  thej^  will  be  souglit  out 
and  treated  as  necessary.  A  club  project  of  this 
sort  for  50  IMc.  is  not,  in  itself,  new.  Nothing  new 
in  the  way  of  equipment  development  resulted 


from  this  one.  AEA  feels,  however,  that  the  proj- 
ect has  accomplished  several  very  worth-while 
things  to  date.  It  has  proven  that  a  club  can 
take  on  a  project  type  that  is  new  to  its  members 
and  in  doing  so  draw  the  members  closer  together 
in  the  common  cause.  It  has  also  proven  our 
democratic  principles  of  majority  rule  can  be 
accepted  with  good  grace  and  that  unity  can 
exist  within  the  amateur  ranks  —  even  among 
those  who  "lost"  an  issue. 

We'll  be  seeing  you  on  50  Mc.

The  Viking  Adventurer 


THE  "Adventurer"  is  a  small  transmitter 
which,  while  no  doubt  having  special  appeal 
to  Novice  licensees  because  it  is  crystal- 
controlled  and  operates  at  a  50-watt  final-ampli- 
fier input  level,  also  would  be  useful  as  an  exciter 
for  a  higher-power  amplifier  in  the  3.5-  to  28-Mc. 
bands.  The  power  output  should  be  ample  for 
driving  a  tetrode  of  fairly  large  power  input.  The 
aluminum  cabinet  has  been  designed  for  good 


» 


The  "Adventurer"  is  a  two-tube  50- 
watt  input  transmitter  covering  the 
amateur  bands  between  .'?..S  and  30 
Me.  The  dual-range  milliammeter 
(0-20  and  0-200  ma.)  can  be  switched 
to  read  either  grid  current  or  plate 
current  in  the  final  amplifier.  The  con- 
trol at  the  upper  right  is  for  the  700- 
niii.  variable  output  rapacitor  of  the 
amplifier  pi  network.  The  slide  switch 
just  below  it  cuts  a  700-/i/af.  fixed  cap- 
acitor in  parallel  for  additional  output 
capacitance. 


shielding  and  the  115- volt  and  keying  leads  (the 
only  ones  that  have  external  connections)  are 
fitted  with  harmonic  filters  for  the  TV  frequen- 
cies. The  transmitter  is  available  only  in  kit  form, 
and  the  only  accessories  required  are  a  key  and 
crj'stals. 

There  are  two  r.f.  tubes,  a  6AG7  oscillator  and 
807  amplifier  doubler.  The  oscillator  uses  the 
Pierce-type  circuit  with  the  crystal  connected  be- 
tween grid  and  screen,  output  being  taken  from 
the  plate.  Conventional  parallel  tuning  with  ca- 


pacitive  coupling  to  the  807  grid  is  used  in  the 
oscillator  plate  circuit.  The  807  plate  tank  is  a 
pi  network  with  constants  selected  so  that  loads 
ranging  50  to  600  ohms  can  be  fed.  In  both  tanks 
the  various  bands  are  covered  by  tapped  tank 
coils,  the  unused  portions  of  which  are  shorted 
out  by  the  bandswitch.  Both  coils  are  sectional- 
wound  to  reduce  the  coupling  between  the  active 
and  shorted  portions  and  thus  minimize  losses  in 


« 


The  oscillator  and  amplifier 
tank  coils  arc  wound  on  ceramic 
forms,  with  sections  for  the  vari- 
ous bands  separated  as  shown  to 
reduce  losses.  The  higher-fre- 
(piency  sections  are  space-wound. 
The  phono-type  connector  at  the 
left  on  the  rear  lip  of  the  chassis  is 
for  coaxial  output  from  the  ampli- 
fier tank. 


the  "dead"  turns.  The  oscillator  and  amplifier 
switch  sections  are  ganged,  but  are  separated  by 
a  shield  partition  to  prevent  unwanted  coupling 
between  the  two  circuits. 

In  the  main,  the  r.f.  circuits  conform  to  stand- 
ard practice  and  are  quite  straightforward.  The 
oscillator  operates  straight-through  on  the  3.5- 
Mc.  band,  80-meter  crystals  being  specified  (al- 
though presumably  a  160-meter  crystal  could  be 
used  for  this  band  if  one  happens  to  be  available). 
For  7-Mc.  operation,  either  80-  or  40-meter  crj's-

tals  may  be  used,  with  frequency  doubling  in  the 
oscillator  plate  circuit  in  the  former  case.  Forty- 
meter  crystals  are  recommended  for  14-Mc.  and 
higher-frequency  operation;  the  oscillator  doubles 
for  14-Mc.  operation,  triples  for  21  Mc,  and 
doubles  for  27-28  Mc,  where  the  807  is  also  used 
as  a  frequency  doubler.  On  21  Mc.  and  all  lower- 
frequency  bands,  the  807  operates  as  a  straight- 
through  amplifier.  Since  the  driving  power  tends 
to  become  excessive  on  the  lower  frequencies,  a 
2700-ohm  1-watt  resistor  is  connected  between 
the  21-Mc.  tap  and  the  cold  end  of  the  oscillator 
tank  coil  (shorting  for  the  higher  frequencies 
moves  progressively  from  the  cold  end)  to  absorb 
some  of  the  excess  power.  This  arrangement  re- 
sults in  reduced  "swamping"  by  the  resistor  on 
14  Mc.  particularly,  and  cuts  out  the  additional 
loading  entirely  on  21  Mc. 

Simultaneous  cathode  keying  of  both  tubes  is 
used  in  the  "Adventurer."  There  is  no  built-in 
provision  for  shaping  of  the  keying  waveform. 
VFO-input  terminals  are  provided,   connecting 


between  the  6AG7  stage  grid  and  ground. 

Plate  and  heater  power  are  both  obtained  from 
the  same  power  transformer.  The  rectifier  is  a 
5U4G,  working  into  a  capacitor-input  filter  con- 
sisting of  two  capacitors  and  a  choke.  The  output 
voltage  is  approximately  450  at  a  full-load  current 
of  150  ma.  Power  leads  are  brought  out  to  an 
octal  socket  on  the  rear  chassis  apron  so  the  power 
supply  can  be  used  for  other  purposes  if  desired. 
The  transmitting  tubes  remain  connected  under 
these  conditions,  but  the  full  d.c.  output  is  avail- 
able for  external  use  if  the  key  is  left  open.  To 
use  the  maximum  available  heater  current  of  2 
amperes  externally  requires  removing  the  oscil- 
lator and  amplifier  tubes  from  their  sockets.  The 
same  "accessory"  socket  can  be  used  to  operate 
a  device  of  low  power  consumption,  such  as  a 
VFO,  with  the  transmitter  in  full  operation. 

The  panel  size  is  7^'  by  10  H  and  the  trans- 
mitter is  83^8  inches  deep.  Like  other  Viking  units, 
the  "Adventurer"  is  a  product  of  the  E.  F.  John- 
son Company.  —  G.G. 


Models  650  and  651  Matchmasters 


THE  B  &  W  "Matchmaster"  is  a  piece  of  test 
equipment  incorporating  a  dummy  antenna, 
standing-wave  ratio  bridge,  and  r.f.  power 
meter  in  one  unit.  It  is  made  in  two  impedance 
levels  matching  the  two  commonly-used  types  of 
coaxial  line.  Model  650  being  set  up  for  52-ohm 
lines  and  Model  651  for  73-ohm  lines.  The  dummy 
antenna,  which  uses  noninductively- wound  wire 
resistors,  has  a  continuous  rating  of  100  watts  and 
an  intermittent  rating  of  125  watts.  Power  in  the 
dummy  antenna  is  measiu'ed  by  means  of  a 
rectifier-type  voltmeter,  using  a  1N34,  connected 
through  a  voltage  divider  across  the  dummy  load. 
The  essentials  of  the  dummy  antenna  and 
s.w.r.-bridge  circuits  are  shown  in  the  accompany- 
ing diagram,  in  which  the  power-reading  volt- 
meter and  switching  details  have  been  omitted. 
One  interesting  feature  is  the  compensating  cir- 


The  "Matchmaster"  is  a  combination  of  dummy  an- 
tenna, r.f.  wattmeter,  and  s.w.r.  bridge,  and  is  useful  for 
testinR  and  adjustment  of  transmitters  and  antenna  sys- 
tems. Dimensions  are  834  by  8)4  by  634  inches.

to  reduce  reactive  effects,  particularly  at  the  high-

ment,  and  to  provide  a  means  for  adjusting  the 
resistance  to  the  proper  value.  The  adjustment  is 
an  internal  one  and  is  made  at  the  factory. 

The  s.w.r.  indicator  uses  the  well-known  re- 
sistance-bridge circuit.  Ri,  R2,  and  R?,  are  equal 
resistors  having  a  value  the  same  as  the  charac- 
teristic impedance  of  the  line  to  be  matched.  Ri 
and  /?5  are  identical  and  are  of  high  value  com- 
pared with  the  other  three,  Ri  being  used  to  iso- 
late the  d.c.  meter  circuit  from  the  r.f.  bridge,  and 
/?5  to  balance  the  shunting  effect  of  R^.  The 
10,000-ohm  variable  resistor  is  for  setting  the 
meter  sensitivity  to  conform  to  the  power  taken 
from  the  transmitter.  The  instruction  book  states 
that  power  inputs  between  10  and  100  watts  will 
permit  j^roper  operation  of  the  bridge. 

An  innovation  in  the  bridge  circuit  is  the  use 
of  a  ballast  lamp,  RT,  to  maintain  the  r.f.  voltage 
applied  to  the  bridge  at  a  reasonably-constant

value  when  different  loads  are  connected  to  the 
output  terminals.  The  ballast,  a  GE  15-\vatt  120- 
volt  miniature-base  lamp,  would  seem  to  be  a 
worth-while  addition  to  such  a  bridge  when  no 
other  means  is  used  for  keeping  the  input  voltage 
constant  (the  imiwrtance  of  this  has  been  stressed 
many  times  in  both  QST  and  the  Hamlbook,  when 
reasonable  accuracy  is  to  be  attained  in  s.w.r. 
measurement) . 

A  three-position  switch  is  used  for  the  various 
functions.  In  one  position  the  d.c.  instrument,  a 
0-1  milliammeter,  is  connected  to  the  line  r.f. 
voltmeter  for  power  measurement.  In  this  posi- 
tion the  s.w.r.  bridge  and  output  connector  are 
disconnected.  In  the  second  switch  position  both 
the  dummy  load  and  s.w.r.  bridge  are  connected 
to  the  input  terminals  and  the  milliammeter  is 
switched  to  the  bridge-indicator  circuit,  while  the 
output  terminals  are  still  disconnected.  This  posi- 


tion permits  adjusting  the  meter  reading  to  full 
scale  for  subsecjuent  s.w.r.  measurement.  The 
third  switch  position  adds  a  connection  between 
the  bridge  and  the  output  terminals,  giving  the 
s.w.r.  reading.  Since  the  dummy  antenna  is  per- 
manently connected  in  all  three  switch  positions 
and  the  s.w.r.  bridge  is  of  the  low-power  type,  the 
"Matchmaster"  cannot  be  left  in  the  line  after 
tests  and  adjustments  have  been  made. 

The  dummy  antenna  is  specified  to  have  a 
standing-wave  ratio  of  1.2-to-l  or  less  at  all  fre- 
quencies up  to  30  Mc,  and  the  power  meter  wall 
give  useful  readings  at  frequencies  between 
500  kc.  and  30  Mc.  —  G.G.

What  About  the  Low-Frequency 
Harmonics? 

A  Serious  Problem  for  the  Amateur  Newcomer 
BY  CHARLES  L.  WOOD,*  W2VMX 


•  Although  most  hams  these  <lays  M'orry 
about  TV  I  from  their  v.h.f.  harmonics, 
W2VMX  points  out  that  even  more 
serious  trouble  ran  be  caused  by  the  low- 
order  (second,  third,  etc.)  harmonics 
that  may  interfere  in  channels  used 
by  important  eommunicalions  services. 
This  should  be  of  special  significance 
to  the  Novice  working  on  the  80-  and  -IO- 
meter hands,  since  the  second  har- 
monies fall  outside  the  bands  assigned  to 
amateurs. 


THE  problem  of  harmonics  in  amateur  radio 
is  bj'  no  means  limited  to  the  matter  of  TVI. 
The  v.h.f.  harmonics  which  so  irk  the 
XYL  and  the  neighbors  have  simply  received 
more  attention  in  recent  years.  Yet  there  are 
many  hams  on  the  air  today  radiating  strong 
signals,  outside  amateur  bands,  that  do  not 
bother  TV  sets.  Too  often,  the  first  inkling  of 
trouble  in  these  cases  is  a  letter  from  the  FCC. 
ARRL  Official  Oliservers  are  sending  many  post 
cards  to  amateurs  in  this  category.  It  is  sincerely 
hoped  that  this  service  will  save  many  hams 
from  FCC  notices.  Our  station  alone  has  sent 
cards  to  several  hundred  different  amateurs  heard 
outside  amateur  bands  in  the  last  few  years.

If  you  would  have  first-hand  knowledge  of  the 
situation,  sweep  the  spectrum  from  7350  to  7500 
kc.  on  any  Sunday  afternoon.  We  have  heard 
harmonics  so  thick  in  this  region  that  some 
stations  couldn't  be  copied  because  of  harmonic 
QRM  from  otheis. 

Granted  that  a  prol)lem  exists,  what  are  we 
going  to  do  al)0ut  it?  Let's  begin  by  asking  where 
this  unwanted  energy  comes  from.  A  harmonic 
fre(iuency  is  simply  an  integral  multii)le  of  some 
given  frecjuency  called  the  Jundamenlal.  For 
instance,  if  your  transmitter  operates  on  :5705 

*609  Park  Ave.,  CollinK-swood  7,  N.  J. 


kc,  the  second  harmonic  is  at  7410  kc.,  and 
the  third  is  at  3  X  3705  or  11,115  kc.  Regardless 
of  the  kind  of  transmitter  you  use,  whether 
homemade  or  store-bought,  small  amounts  of 
energy  at  these  harmonic  frequencies  are  present 
in  your  final  tank  along  with  the  useful  energy 
at  the  fundamental  frequency.  Such  energy  can 
create  problems  whenever  (1)  there  is  a  large 
amount  of  harmonic   energy  generated   or   (2) 


—CAM  CttEAT& 
PROI3L.EMS 


when  conditions  exist  under  which  the  harmonic 
emergy  may  be  easily  radiated.  Either  condition 
alone  may  be  bad;  the  combination  is  an  invita- 
tion for  FCC  action. 

The  files  of  our  station  contain  quite  a  number 
of  letters  and  comments  from  the  stations  to 
whom  we  have  sent  ARRL  Official  Observer 
cards.  These  letters  show  that  the  chief  reasons 
for  the  harmonics  we  have  heard  are,  in  order, 
carelessness,  ignorance  of  the  situation,  and  the 
inability  to  correct  the  problem.  Let's  go  through 
the  most  common  mistakes  and  see  whether  we 
can  avoid  these  pitfalls. 

Use  a  Wavemeier 

The  first  question  in  chasing  low-frequency 
harmonics  should  be;  this:  To  what  band  is  the 
final  tank  circuit  tuned?  Many  Novices  are 
building  bandswitching  rigs.  Many  others  have 
built  rigs  in  which  the  final  tank  capacitor, 
without  any  change  in  the  tank  inductor,  will 
tune,  for  instance,  to  both  3.7  and  7.4  Mc.  In 
the  case  of  the  bandswitching  transmitter,  the 
danger  alwa.ys  exists  that  the  operator  will, 
without  thinking,  leave  a  3.7-Mc.  crystal  in 
l)lace  when  the  bandswitch  is  turned  to  the  7-Mo. 
band.  A  frequency-doubling  action  takes  place 
and  the  full  output  of  the  transmitter  i.«  then 
radiated  on  a  frecjuency  outside  the  amateur 
bands.  In  the  case  of  the  transmitter  which  will 
tun(>  l)oth  bands  without  replacing  the  inductor, 
th(^  oi)erator  must  at  all  times  beware  of  the 
resonance  point  which  uses  the  lesser  capacitance 


42 


QST  for 


of  the  tuning  capacitor.  A  special  case  of  this 
same  trouble  may  exist  where  the  transmitter 
is  operated  from  a  crystal  or  VFO  in  the  160- 
meter  region.  In  such  a  transmitter  it  is  some- 
times possible  to  tune  a  multiplier  stage  to  the 
third  harmonic  around  5.4  Mc,  instead  of  the 
intended  second  harmonic  near  3.7  Mc.  Again, 
it  sometimes  happens  that  the  output  of  a 
doubler  stage  tuned  to  3.7  Mc.  may  contain 
sufficient  energy  at  5.4  Mc.  to  drive  a  final  so 
that  it  will  show  a  pronounced  dip  at  resonance 
at  5.4  Mc. 

What  can  be  done  to  make  sure  the  final  is 
tuned  to  the  right  band?  The  FCC  regulations 
provide  that  the  frequency  of  the  transmitter 
must  be  checked  from  time  to  time.  Unfor- 
tunately, we  can't  rely  on  the  receiver  to  tell  us 
about  harmonics.  If  we  have  a  3.7-Mc.  trans- 
mitter right  next  to  the  receiver,  we  will  probably 
hear  a  signal  every  3.7  Mc.  right  up  the  dial. 
The  instrument  we  need  to  be  sure  of  the  right 
band  is  called  a  wavcmeter.  An  e.xcellent  unit 
that  can  be  built  for  just  a  few  cents  was  de- 
scribed in  QST  recently,  comiilete  with  a  cut-out 
dial.^  A  more  elaborate  and  more  sensitive 
instrument   was    described    by    another   author 


in  the  February  issue  of  this  year."  The  latter 
can  be  used  to  indicate  the  presence  of  very  small 
amounts  of  harmonic  energy  at  5.4  and  11  Mc. 

Tank-Circuit  Q 

If  we  find  that  the  final  tank  is  not  tuned  to 
the  right  band,  the  necessary  correction  is  easy 
enough.  If  the  tank  is  tuned  to  the  right  place 
but  there  is  enough  unwanted  energy  to  give  an 
indication  on  the  wavemeter,  this  is  another 
problem.  Then  we  must  find  out  whether  the 
unwanted  signal  is  coming  from  the  final  or  from 
some  previous  stage.  Always  correct  the  trouble 
on  the  lowest  power  level. 

High-Q  tank  circuits  will  minimize  harmonics 
in  lower-level  stages.  Harmonic  generation  in 
ampUfier  stages  can  be  minimized  by  reducing 
drive    to    the    lowest    practical    level.    Consult

Sept.,  1952.

1955.

April,  1955. 

*  Although  the  minimizing  of  the  number  of  turns  in  the 
link  coils  is  desirable  in  reducing  harmonic  output,  it  has 
been  pointed  out  previously  in  QST  that  adequate  output 
coupling  sometimes  requires  a  larger  link  winding  than 
that  supplied  by  coil  manufacturers.  This  is  particularly 
true  when  working  into  higher-impedance  lines,  such  as 
300-ohm  Twin-Lead.  —  Ed. 


the  Handbook  for  proper  grid  drive,  and  do  not 
exceed  this  figure.  These  are  just  two  of  the 
waj's  to  help  cut  harmonic  generation  in  the 
transmitter.  After  we  have  worked  on  this 
angle,  we  will  probably  want  to  ask  if  we  can 
cut  down  the  radiation  of  unwanted  frequencies. 
The  answer  in  most  cases  is  yes. 

Antenna  Coupler 

Let's  make  up  our  mind  that  some  sort  of 
antenna-tuning  device  is  always  in  order,  not 
only  to  get  the  greatest  efficiency  from  the  ra- 
diator, but  also  to  cut  down  spurious  signals. 
Good  designs  are  given  in  the  Handbook,^  and 
many  excellent  commercially-built  units  and  kits 
are  on  the  market.  Where  tuners  provide  for  a 
grounding  arrangement,  this  should  always  be 
the  very  liest  and  most  direct  ground.  One 
special  precaution  is  in  order,  based  on  reports 
we  have  received.  Don't  overcouple  the  trans- 
mitter to  the  antenna  or  tuner!  Beginners  some- 
times get  the  idea  that  the  more  turns  there 
are  in  a  link,  the  more  r.f.  will  be  coupled  to 
the  antenna.  As  a  result,  we  have  heard  of  links 
of  ten  and  twenty  and  even  thirty  turns.  Re- 
member that  such  an  arrangement  is  not  only 
a  link  but  a  very  effective  capacitive-coupling 
device  —  something  harmonics  love  like  mice 
love  cheese.  Any  two  pieces  of  metal  separated 
by  an  insulator  form  a  capacitor  of  sorts,  whether 
these  be  flat  plates  (as  in  an  air  variable)  or 
rolled  foil  (as  in  a  paper  capacitor)  or  in  coil 
form.  Notice  commercially-made  coils  for  the 
40-  and  80-meter  amateur  bands.  Usually  these 
have  only  two  turns,  or  three  at  the  most."* 

Measures  which  >'ou  have  probably  already 
taken  in  connection  with  TVI  will  also  help  with 
your  low-frequency  harmgnics.  For  example:  A 
Faraday  shield  in  the  final  tank  link,  coax  from 
this  link  to  the  shielded  antenna  tuner,  and  a 
shielded  link  in  the  tuner  unit  itself,  grounding

of  center  taps  of  coils  in  Imlanced  systems, 
and  the  like,  are  all  l)eneficial.  A  low-pass  filter 
will  not  have  any  effect  whatever  on  low-fre- 
quency harmonics,  since  it  is  usually  designed  to 
pass  everything  below  30  Mc. 

There  are  always  a  few  special  cases,  and  it 
may  be  that  your  rig  seems  to  radiate  unwanted 
signals  despite  everything  that  you  have  done 
to  it.  This  is  a  good  place  for  a  huddle  at  the 
local  club,  as  two  heads  are  usually  better  than 
one  at  this  point.  If  it  is  a  manufactured  item, 
write  telling  the  maker  exactly  what  happens, 
and   follow   his   suggestions   carefully.    If  your

The  Buffalo  Area  RACES  Organization 

Getting  Organized  for  Civil  Defense  Service  in  Erie  County,  N.  Y. 

BY  C.  E.  JOHNSON,  JR.,*  W2PPY 


•  In  pa!i<t  (JSTs  Me  have  given  you  much 
infurniation  and  advice  on  how  to  get 
set  up  for  RACES.  This  article  will  tell 
you  ahoul  Erie  County's  working  organi- 
zation,  how   it  got   that   way  and   why. 


ERIE  COUNTY,  New  York,  is  the  13th  largest 
county  in  the  United  States  and  has  an  area 
of  1042  square  miles.  There  are  three  cities 
within  its  boundaries,  namely,  Buffalo,  Lacka- 
wanna and  Tonawanda  with  a  total  population 
of  approximately  1,000,000  people. 

The  task  of  establishing  suitable  RACES  net- 
works within  a  county  of  this  size  was  a  formida- 
ble one.  The  local  civil  defense  director  required 
communications  via  amateur  radio  from  one  end 
of  the  coinitry  to  the  other.  The  terrain  in  the 
county  ranges  from  flat  to  extremely  hilly  and  the 
problems  of  reliable  communications  were  many 
and  varied. 

Our  first  task  was  to  decide  how  and  on  what 
frequencies  the  required  networks  would  be  estab- 
lished. A  quick  check  of  the  RACES  freciuencies 
available  to  Erie  County  showed  we  had  10-,  6- 
and  2-meter  frequencies  available.  After  much 
discussion  it  was  decided  to  build  our  networks 
around  6  and  2  meters,  although  there  were  many 
10-meter  mobile  units  available.  Ten  meters  had 
been  found  undependable  for  short-range  com- 
munications. In  the  civil  defense  test  of  1958  this 
band  opened  up  and  stations  from  all  parts  of  the 
country  were  calling  our  main  control  station 
causing  confusion  and  chaos. 

Erie  County  has  two  control  centers,  four  zone 
headquarters,  six  aid  check  points  and  fifteen 
township  report  centers.  The  main  control  center 

♦Radio  Officer,  Erie  County  Civil  Defense,  Room  218, 
City  Hall,  Buffalo,  N.Y. 


is  located  in  the  town  hall  in  Lancaster,  N.  Y, 
This  station,  and  its  alternate,  are  able  to  oper- 
ate on  any  RACES  frequency  assigned  to  Erie 
County  by  state  civil  defense.  Three  si.x- meter 
nets  are  controlled  by  17-watt  transmitters  feed- 
ing ground- plane  antennas:  the  Zone  Headquar- 
ters Net  on  53.6  Mc;  the  Aid  Check  Point  Net, 
50.6  Mc;  and  the  Support  Area  Net  on  53.74 
Mc.  This  small  amount  of  power  seems  ample  for 
the  distance  to  be  covered.  All  other  nets  are 
controlled  by  100-watt  crystal-controlled  trans- 
mitters feeding  ground-plane  antennas  on  2  me- 
ters. One  transmitter  handles  mobile  control  for 
the  NE  and  SW  Zone  Headquarters  on  145.200 
and  145.320  Mc.  respectively.  A  similar  trans- 
mitter is  used  to  control  the  mobile  units  for  the 
NW  and  SE  Zone  Headquarters  operating  on 
147.000  and  147.120  Mc.  respectively. 

The  Township  Net  operates  on  a  frequency  of 
145.440  Mc.  and  the  State  Command  Net,  which 
is  the  main  link  between  the  target  city  and  the 
N.  Y.  State  CD.  Headquarters  in  New  York 
City  operates  on  a  frequency  of  145.680  Mc.  Any 
traffic  for  State  is  relayed  via  this  net  to  a  high- 
powered  station  called  Area  Ten  Control  Station, 
on  3509.5  or  3993  kc.  located  outside  of  the  target 
area.  There  are  two  spare  transmitters  available 
at  each  Control  Center. 

The  main  target  city,  Buffalo,  is  divided  into 
four  zones.  These  zones  are  actually  fully  equipped 
control  points  with  each  service  represented. 
Each  of  our  zone  Headquarters  has  a  RACES 
installation  capable  of  controlling  any  of  nine 
mobile  units  assigned  to  it,  or  of  contacting  the 
Control  Center  should  the  need  arise.  The  mobile 
control  transmitter  is  100  watts  and  the  unit  for 
contacting  Control  Center  is  17  watts,  both  using 
ground-plane  antennas.  On  2  and  6  meters  re- 
spectively the  mobile  units  are  small,  compact

The  ARRL  National  Emergency  Coordinator's  Report  of  the  League's 
Participation  in  FCDA's  Yucca  Flat  Atomic  Test  Observer  Program 

BY  GEORGE  HART,  WINJM 


"The  shot  is  on!" 

None  of  us  really  believed  it.  There  had  been 
too  many  such  announcements  during  the  pre- 
vious nine  da\-s  to  have  this  one  stir  up  any  excite- 
ment. All  it  meant  to  most  of  us  (that  is,  those  of 
us  who  were  still  waiting)  was  another  wearying 
bus  ride  to  the  AEC's  Nevada  Test  Site,  90  miles 
away,  probably  to  be  followed  by  another  last- 
minute  postponement.  By  this  time,  we  were 
hardened  to  such  disappointment.  Already  we 
had  journeyed  to  Yucca  Flat  three  times,  stood 
around  in  the  freezing  cold  (and  once  in  the 
freezing  rain),  went  completely  without  sleep, 
except  what  we  could  snatch  during  the  bus  ride, 
only  to  be  returned  to  Las  Vegas  without  having 
seen  anything  except  a  lot  of  dry  desert. 

It  was  Wednesday  evening,  May  4th.  To  most 
of  us  observers,  the  weather  looked  favorable. 
There  was  very  little  breeze  and  visibility  was 
good.  A  scattering  of  high  cirrus  clouds  was  ex- 
pected to  dissipate  before  morning.  Once  before, 
just  a  week  ago,  the  weather  had  looked  exactly 
like  this,  so  we  weren't  too  optimistic.  Neverthe- 
less, at  0400,  the  announcement  was  made  that 
the  shot  was  "on."  Our  long  days  of  waiting 
seemed  about  to  pay  off.  We  kept  our  fingers 
crossed. 

The  time  from  then  on  flew  rapidly.  At  0430 
daylight  started  to  appear  in  the  east,  but  it  was 
still  quite  dark  to  the  north,  in  the  direction  of 
the  shot  tower.  At  0500,  observers  and  media 
(press,  radio,  TV,  etc.)  personnel  started  shifting 


around  to  find  better  vantage  points  to  watch  the 
shot.  At  0510  minus  thirty  seconds  we  adjusted 
our  high-intensity  dark  glasses  (through  which 
ordinary  sunlight  is  scarcely  visible)  and  listened 
to  the  countdown  over  the  public-address  system. 

The  "Shot" 

At  exactly  "zero"  there  came  a  blinding  white 
flash  (bright  yellow  through  our  glasses)  and  a 
sudden  wave  of  heat.  After  three  seconds  we  cau- 
tiously removed  our  glasses  and  watched  the 
fireball  form  into  its  typical  mushroom  and  fade 
through  the  color  spectrum,  from  yellow  to  orange 
to  red  and  finally  to  purple.  Within  fifteen  seconds 
all  that  was  left  was  a  gigantic  black  mushroom 
with  a  whitening  cap  (ice  crystals).  This  cap  grad- 
ually detached  itself  from  the  rest  of  the  mush- 
room and,  rising  gradually,  it  turned  Ijrown.  Just 
beneath  it  a  scraggly  black  cloud  was  forming, 
and  at  the  base  a  cottony  gray  cloud  of  dust  was 
spreading  rapidly.  The  brown  cloud,  highly  radio- 
active particles  remaining  from  the  shot  tower, 
rose  rapidly  and  approached  the  observer  area. 
When  it  reached  40,000  feet,   however,   it  was 


•  At  the  invitation  of  FCDA,  the  League 
sent  its  NEC  to  take  part  in  Operation 
Cue.  Some  of  his  observations,  including 
participation  by  amateurs,  are  presented 
herewith.

caught  in  a  "shear"  wind  and  dispersed.  At  the 
end  of  an  hour,  it  was  no  longer  visible.  The  black 
cloud,  also  radioactive  but  less  so,  rose  more 
slowl>'  and  was  eventually  also  dispersed.  The 
gray  cloud  of  dust  spread  laterally  luitil  it  covered 
an  area  many  miles  in  diameter,  eventually  per- 
meating our  observer  area;  the  radioactivity  in 
this  dust  cloud  was  said  to  lie  negligible. 

The  shock  wave,  arriving  completely  unan- 
nounced about  forty  seconds  after  zero,  took 
most  of  us  by  surprise.  It  was  a  very  sharp  and 
sudden  "blam!"  rather  than  the  deep  rumbling 
we  had  expected.  At  our  distance  it  was  not 
strong  enough  to  knock  anybody  over,  but  it 
startled  many  observers  and  stirred  up  a  con- 
siderable amount  of  dust. 

Mass  Feeding 

Now  the  mass  feeding  teams,  which  had  been 
feeding  us  coffee  and  doughnuts  all  night,  swung 
into  action  to  feed  us  breakfast.  These  people, 
coming  from  all  over  the  United  States,  were 
part  of  the  Civil  Defense  Field  I']xercise  group 
which  was  stationed  at  Mercury,  Nevada.  They 
also  fed  us  a  good  substantial  lunch  on  the  follow- 
ing day  on  shot-plus-one  tour  of  the  forward 
area. 

Hams  in  Forward  Area 

The  gi'oup  of  vohmteers  who  were  stationed 
in  the  forward  area  10,500  feet  from  ground 
zero  joined  us  for  breakfast.  There  were  two 
amateurs  among  them  (out  of  sixteen  people)  — 
W2TII,  from  Newark,  N.  Y.,  and  W6LYF,  from 
San  Diego,  Calif.  They  both  appeared  somewhat 
shaken  up,  hxxi  otherwise  little  the  worse  for  their 
experience.  Howard,  W2TII,  was  left  without 
appetite  for  breakfast,  so  we  dined  on  one  of  the 
observer  benches  with  W6LYF  and  had  a  very 
pleasant  chat.  Since  then,  we  have  asked  both 
of  them  for  a  brief  paragraph  describing  their  ex- 
periences in  the  forward  trench.  Each  supplied 
us  with  more  than  that,  so  we  had  to  condense 
them  to  the  following: 

W2T1I:  "The  most  blinding  light  I  ever  saw, 
equal  to  100  suns,  was  projected  into  the  bottom 
of  the  trench.  ...  I  became  conscious  of  the 
trench  shaking  from  side  to  side.  .  .  .  Dirt  fell 
in  from  the  sides.  ...  A  terrific  BANG  split  the 
air,  seeming  to  come  from  everywhere  overhead. 
...  All  sorts  of  del)ris  was  flying  over  our  trench. 
.  ,  .  Then  the  command  'Out  of  the  trench!' 
.  .  .  Two  of  the  Jeeps  had  their  lights  turned  on 


Part  nf  the  California  Communications  Cara- 
van. Eight  amateurs  were  in  the  crew  of  25 
who  manned  these  units.  The  buses,  completely 
equipped  with  spotlights,  floodlights,  p. a.  sys- 
tem and  multitudinous  transmitting  equipment 
(note  the  whips),  were  used  for  control  purposes. 
Radio  cars  were  assigned  to  c.d.  service  chiefs. 
All  these  units  operated  with  the  C.D.  Field 
Exercises  and  were  stationed  at  Mercury, 
Nevada. 


by  the  blast.  ...  As  the  base  of  the  atomic 
cloud  approached  menacingly,  we  loaded  into  our 
Jeeps  and  got  out  of  there."  W2TII  is  RACES 
Radio  Officer  for  Wayne  County,  N.  Y.  He 
carried  a  Gonset  transmitter  into  the  trench  with 
him. 

W6LYF:  "  'Shot'  time  found  us  kneeling  in 
tren«h  with  fiber  glass  helmets,  goggles  and  respi- 
rators in  place,  hands  covering  ovu'  e>^es  and  hold-

ing  our  breath.  Could  see  the  light  from  shot 
through  covering.  I']arth  started  to  rumble  (like 
an  earthquake)  and  then  came  shock  wave.  Rocks 
and  dirt  fell  into  trench,  then  came  the  noise  of 
the  l)last,  loud  and  sharp.  At  shot  plus  fifteen 
seconds,  we  were  standing  in  trench  looking  at 
the  enormous  cloud,  brown  with  pink  tints,  rising 
before  us.  At  shot  plus  five  minutes  we  were  in 
Jeeps  headed  for  Media  Hill  six  miles  away  and 
breakfast."  \\'(')LYF  is  Radio  Chief  for  California 
Region  10  (San  Diego  and  Imperial  Counties). 
At  Operation  Cue,  he  was  a  member  of  the 
California  communications  team  which  provided 
communications  for  FCDA-sponsored  field  ex- 
ercises before  and  after  the  shot.

QST  for 


Post- Shot  Briefings 

The  day  following  the  shot  we  made  our  last 
(sixth)  trip  to  Yucca  Flat,  for  most  of  us  com- 
pleting a  total  of  over  1000  miles  of  travel  m  the 
buses  provided.  The  purpose  of  this  trip  was  to 
observe  the  destruction  of  ' '  Doom  Town     by  the 
atomic   blast.    From   a   communications    stand- 
point   let  it  be  said  that  radio  equipment  stands 
up  well  under  an   atomic  blast,   provided  it  is 
not  much  closer  than  a  mile  from  ground  zero. 
Even   then,    if   properly   protected   by   shelters, 
it  has  a  good  chance  of  remaining  in  operating 
condition.  A  250-watt  broadcast  transmitter  in- 
stalled in   one   of   the   steel-reinforced   concrete 
block  houses  at  the  4700-foot  line  was  in  actual 
operation  on  the  Conelrad  frequency  of  1240  kc, 
using  the  call  K()2XBM.  This  rig,  sponsored  by 
RETMA    was  in   operation   until   five   minutes 
before  the  ))last.  After  the  blast  it  did  not  return 
to  the  air  immediatelv,  but  the  trouble  was  found 
to  have  been  power  failure;  the  equipment^  re- 
mained in  operating  condition  and  returned  to 
the  air  shortly  after  the  blast. 

Other  radio  communic-ations  equipment  m 
this  and  similar  houses  was  found  to  be  undam- 
aged and  still  in  working  condition.  Of  the  two 
towers  closest  to  the  blast,  the  guyed  standard 
broadcast  tower  remained  standing,  although 
very  slightly  bowed.  Th<«  ungu>ed  l20-ft.  tower 
had  been  broken  off  in  the  middle.  ^^ 

"Doom  Town"  had  become  "Survival  City, 
but  not  everybody  survived.  "People"  (manne- 
quins, of  course)  in  the  open  didn't  have  a  chance, 
what  with  the  combined  effects  of  heat,  radiation 
and  blast,  each  lethal  by  itself.  Those  in  the 
above-ground  parts  of  the  various  houses  were 
killed  either  h\  blast  or  missiles.  Only  those  in 
basement  shelters  survived,  although  many  were 
injured.  Naturally,  the  closer  to  ground  zero  the 
greater  the  destruction.  Normally-constructed 
houses  4700  ft.  from  ground  zero  were  reduced 
to  rubble,  but  the  specially  built  concrete-and- 
steel  block  houses  stood  up  well. 

Amateurs  in  Field  Exercises 
There  were  a  few  amateurs  in  the  observer  and 
media  groups,  but  most  of  them  were  amateurs 
incidental  to  some  other  capacity.  The  real  com- 
municating was  done  by  the  Field  Exercise  group 
stationed  at  Mercury,  just  a  few  miles  from  the 
shot  area.  This  included  amateurs  belonging  to 
the  CaUfornia  communications  team,  which  came 


in  convoy  from  Sacramento  starting  on  April 
17th,  traveling  via  Los  Angeles  and  picking  up 
members  along  the  way.  Personnel  in  the  convoy 
numbered  about  25,  including  the  following  ama- 
teurs: W6s  JN  ASI  RLB  CIS  LY  CV  OU  and 
WYT.  Equipment  consisted  of  two  completely- 
equipped  communications  buses  and  several  cars 
(see  cut)  operating  in  the  Disaster  Communica- 
tions Service  (1761.5  kc.)  and  47  Mc.  During  the 
period  of  the  actual  exercise,  no  amateur  fre- 
quencies were  used.  One  bus  was  stationed  at  the 
Observer  Area  on  Media  Hill,  the  other  at  field 
crew  headquarters  located  approximately  a  mile 

forward.  i      j    ti. 

The  communications  gang  worked  hard.  The 
Field  Exercises  were  no  picnic.  Troubles  de- 
veloped ^^^th  the  equipment  (as  they  always  do) 
necessitating  long  hours  of  trouble  shooting. 
Some  special  communications  arrangements  had 
also  to  be  set  up,  necessitating  some  equipment 
changes.  Most  of  this  work  was  done  out  in  the 
open  which,  in  the  desert  at  that  time  of  year, 
means  a  scorching  sun  and  swirling  dust  during 
the  day,  i^enetrating  cold  dropping  far  below 
freezing  at  night.  -r^.   .  .     x 

W6CIS  (ex  ARRL  Director,  Pacific  Division) 
received  special  permission  from  the  AEC  to 
use  his  call  from  one  of  the  buses  to  keep  in 
contact  with  home  offices  in  California.  He 
fired  up  one  of  the  rigs  using  8i:^s  running  250 
watts  to  an  18-foot  base-loaded  whip  mounted 
atop  the  bus.  Power  was  supplied  by  a  3.5-kw. 
generator  which  is  standard  equipment  on  the 
buses.  Much  traffic  was  handled,  with  the  as- 
sistance of  many  California  amateurs,  on  the 
California  Civil  Defense  Net  frequency  of  3501 
kc.  and  other  frequencies.  This  circuit  came  m 
mightv  handy  for  getting  word  back  home  in 
lieu  of  the  greatly-overtaxed  telephone  facilities 
through  Las  Vegas.  In  addition  to  personal  traf- 
fic, much  civil  defense  official  traflftc  was  also 
handled.  W6CIS  lists  and  wishes  to  thank  the 
following  stations  for  having  assisted  in  keeping 
this  traffic  moving:  W6s  SWP  BP  SDR  CLV 
E\R  HOR  ATO  JGJ  CJP  IZG  KB  ^YR  JDG 
CGQ  JKW  PQW  IRJ  KM  J,  K6s  JOQ  DM  H\T

ing from  W6CIS/7.

QST- Volume  IV 

Part  II  \  — 1954  Supplement  to  the  Foreword  to  the 
Index  to  Volume  IV  of  QST 


ONE  of  the  puzzles  which  I  have  been  unable 
to  solve,  from  the  data  appearing  in  Vol- 
umes III,  IV,  and  V  of  QST,  is  this:  how 
many  "tube"  transmitters  were  actually  in  oper- 
ation at  amateur  stations  in  the  U.  S.  A.  as  of 
approximately  July  1,  1921? 

It  finally  occurred  to  me  that  it  might  l)e  inter- 
esting to  examine  the  published  lists  of  "Calls 
Heard,"  from  January,  1920  (when  the  first  ex- 
press reference  to  a  "tube"  set  appeared  in  that 
department  of  the  magazine),  up  to  and  including 
August,  1921,  when  the  lists  of  stations  heard 
during  June,  1921,  were  published.  Accordingly, 

I  have  done  this ;  and  I  have  separated  from  those 
lists  the  stations  which  various  reporters  identi- 
fied as  using  c.w.,  i.c.w..  buzzer-modulated  teleg- 
raphy, and  'phone.  To  give  the  reader  some  sort 
of  an  idea  of  when  each  "tube"  station  first  got 
into  operation,  I  have  also  listed  the  issue  and 
page  of  QST  where  its  call  was  first  published 
in  "Calls  Heard";  and  I  have  identified  the  re- 
porting station.^ 

No  attempt  was  made  to  follow  possible 
changes  from  i.c.w.  to  c.w.,  or  from  c.w.  to 
'phone.  I  have  simply  listed  the  description  of  the 
type  (or  tvpes)  of  transmission,  as  first  reported 
in  QSr. 

Unlike  low-powered  spark  transmitters,  v.t.  rigs 
were  potent  distance-getters.  Therefore,  I  believe 
that  almost  all  of  them  were  rather  promptly  re- 
ported in  "Calls  Heard."  A  possible  exception 
would  be  the  low-powered  'phone  stations  which 
would  have  little  range;  but  I  doubt  if  many  such 
stations  were  in  existence  during  the  period 
studied. 

The  geographical  distribution  of  these  "tube" 
sets,  as  between  the  nine  districts,  is  indicated  by 
the  list  —  to  some  extent,  at  least. 

The  totals  are  as  follows: 

Unlicensed 2 

First  District 93 

Second  District 158 

Third  District 45 

Fourtli  District 11 

Fifth  District 9 

Sixth  District 28 

Seventli  District 7 

Eighth  District 126 

Nintli  District 52 

Total 531 

In  addition,  5  Canadian  v.t.  stations  were 
listed    in    "Calls    Heard";    and    23    short-wave 

Arm\',  Nav}',  commercial,  or  government  v.t. 
stations  appeared  there. 

t  For  previous  installments  see  following  Q^T  references; 
Part  I  of  "Q.Sr— Volume  IV,"  July,  1955;  "Q.ST— Vol- 
ume I,"  October,  1954;  "QST  —  Volume  II,"  February, 
1955;  Part  I  of  "Q.ST— Volume  III,"  March,  1955;  Part 

II  of  "QST  —  Volume  III,"  April,  1955;  Part  III  of  "QST 
—  Volume  III,"  June,  1955. 

1  For  absolute  accuracy,  it  probably  would  be  necessary 


As  will  be  seen  by  the  second  table,  following 
the  compilation  of  data  from  "Calls  Heard," 
there  were  some  additional  v.t.  stations  not  ap- 
pearing in  the  published  lists  of  "Calls  Heard" 
which  were  referred  to  in  the  pages  of  QST, 
between  January,  1920,  and  August,  1921. 
(January,  1920,  is  in  Volume  III;  August,  1921, 
is  in  Volume  V.)  The  "score"  on  these  is  as 
follows: 

Unlicensed 1 

First  District 12 

Second  District 4 

Third  District 7 

Fourth  District 1 

Fifth  District 3 

Sixth  District 1 

Seventh  District 3 

Eighth  District 6 

Ninth  District 8 

Total  additional  stations 46 

(Including  2  not  referred  to  by  Call- Letters) 

In  Canada,  3  additional  v.t.  stations  are  shown 
(including  one  which  is  referred  to  by  the  name  of 
its  owner  and  not  by  call  letters). 

These  two  lists  (and  the  appended  tables, 
which  give  details)  demonstrate  that  at  least  577 
amateur  v.t.  transmitters  had  "come  onto  the 
air"  in  the  U.  S.  A.  by  July  1,  1921.  The  ques- 
tion remains:  how  many  more  amateur  v.t.  in- 
stallations were  in  the  United  States  as  of  that 
same  date? 

I  can  only  make  a  guess  on  this;  and  my  best 
guess  is :  not  over  another  400  —  making  a  total 
for  the  United  States,  as  of  July  1,  1921,  of  977 
amateur  v.t.  stations. 

As  of  June  30,  1921,  the  total  number  of  all 
amateur  stations  licensed  by  the  Department  of 
Commerce  had  reached  10,809.  See  page  68  of 
Two  Hundred  Meters  and  Down,  by  the  late 
Clinton  B.  De  Soto,  where  it  is  said: 

.  .  .  The  Department  of  Commerce  reported 
10,809  licensed  amateur  stations  at  the  end  of  the 
fiscal  year  on  June  30,  1921,  an  increase  of  90 
per  cent.   .  .   . 

If  my  guesses  as  to  the  numbers  of  licensed  sta- 
tions using  "tube"  transmitters,  as  of  the  two 
dates  (July  1,  1920,^  and  July  1,  1921),  are  com- 
pared, it  will  be  seen  that  the  indicated  increase, 
in  the  numl)er  of  v.t.  sets,  777  additional  v.t.  sets, 
is  388.5%. 

I  think  that's  "about  right." 


to  check  and  re-check  each  list  of  "Calls  Heard,"  and  to 
transfer  the  items  of  information  to  pvmched  cards;  and  to 
run  the  latter  through  an  IBM  tabulator.  This  I  have  not 
done;  but  I  have  tried  very  hard  to  avoid  errors. 

2  It  was  "not  over  200  stations,"  as  of  July  1,  1920.  See 
"Foreword  to  the  Index  to  Volume  III,"  QST  for  March, 
1955,  page  51.

QST  for 


On  the  same  premise,  one  amateur  station  in 
28.59  had  a  "tube"  transmitter  as  of  July  1, 
1920;  and  one  amateur  station  in  11.06  had  one, 
as  of  July  1,  1921. 

Again,  I  think  those  figures  are  "about  right." 

Remember,  please,  that  on  the  above  subject 
I  cannot  offer  proof.  All  I  can  do  is  to  hazard  an 
intelligent  guess  based  on  my  recollection  of  ac- 
tual operating  conditions  and  on  the  data  above 
set  forth. 

On  another  subject  mentioned  in  my  "Fore- 
word to  the  Inde.x  to  Volume  IV  of  QST,"  I 
would  also  like  to  add  a  few  words: 

As  to  the  short  waves  (meaning  those  below 
200  meters)  there  is  some  later  evidence  showing 
that  amateurs,  in  general,  lacked  proper  receiving 
apparatus  for  picking  them  up;  and  which  shows 
that  this  condition  of  affairs  lasted  for  a  con- 
sideral)le  period  of  time.  For  instance: 

In  the  May  (1924)  issue  of  QST  (Volume 
VII),  at  page  10,  Dr.  A.  Hoyt  Taylor,  Physicist, 
U.S.N.,  in  his  article  called  "The  Navy's  Work 
on  Short  Waves,"  stated  as  follows: 

.  .  .  Our  interest  in  short  waves  is  by  no  means 
a  new  one.  Since  1917  one  of  the  standard  waves  on 
board  every  battleship  has  been  150  meters.  From  a 
modern  point  of  view  the  apparatus  is  pretty  crude, 
being  a  peculiar  type  of  spark  set  which  is  now  of  no 
particular  interest ;  nevertheless  occasionally  extraor- 
dinary long  distances  were  reached  with  it. 

Had  amaU'ura  in  the  last  few  years  had  receivers 
capable  of  tuning  down  below  200  meters,  we  ivould 
doubtless  have  had  a  great  many  reports  on  our  trans- 
missions on  150  meters  by  these  ships.  Plans  are  now 
under  way  to  replace  this  old  equipment  with  mod- 
ern tube  sets  of  our  own  design.  .  .  .  [Italics  added 
by  S.B.Y.] 

In  Volume  VI  of  QST  I  have  also  run  across 
some  additional  material  on  early  amateur  work 
with  small  "tube"  transmitters  which  was  done 
for  the  purpose  of  QRM  avoidance;  and  I  would 
like  to  refer  to  it  now: 

At  12,  March  1923,  S.  Kruse  (Technical  Editor 
of  QST),  in  an  article  entitled  "Exploring  100 
Meters,"  described  some  preliminary  e.xperi- 
raents  on  waves  about  170  meters  long,  as 
follows: 

"...  In  the  winter  of  1920-21,  mainly  to  get 
away  from  NSF's  chopper  and  NAA's  arc  mush,  we 
at  Washington,  D.  C,  began  to  feel  our  way  down- 
ward. To  our  pleased  surprise  we  found  that  our 
regular  sets  would  work  easily  below  170  meters  if 
anyone  could  be  induced  to  get  down  and  listen  for 
them.  A  low-powered  tube  set  in  Washington  and  a 


small  spark-tube  set  in  Hyattsville,  Md.,  were  able 
to  work  beautifully  without  any  interference  at  all 
from  NSF,  NAA  or  anything  else  on  any  wavelength, 
although  3RP  at  Hyattsville  was  using  only  a  West- 
ern Electric  'E'  tube  driven  by  a  Ford  spark  coil. 
His  signals  at  Washington  (8  miles)  were  so  intense 
that  the  phones  were  normally  left  on  the  table. 
The  other  station,  3ABI,  was  able  to  work  ITS  and 
IQP  whenever  they  could  be  induced  to  tune  down 
—  again  there  was  no  interference.   .   .   . 

To  those  readei-s  who  are  interrested  to  know 
what  type  of  amateur  short-wave  work  next  fol- 
lowed the  first  "dips"  below  200  meters  (which 
were  motivated  by  a  desire  to  avoid  interfer- 
ence), I  strongly  recommend  close  study  of  the 
balance  of  this  same  article  by  Mr.  Kruse.  It 
recites:  the  January  (1922)  tests  of  Mr.  Boyd 
Phelps,  at  Minneapolis,  Minnesota,  on  100 
meters;  Phelp's  later  tests,  in  the  spring  of  1922 
(after  he  had  moved  to  Hartford,  Connecticut, 
and  had  joined  QST's  staff);  the  Jaimary  (1923) 
tests  between  9ZN  and  IHX,  3XM,  IQP,  3ALN, 
3JJ,  3APV,  and  the  listening-station  of  Mr.  A.  L. 
Budlong  (at  Washington,  D.  C);  and  also  the 
Februarv,  1923,  tests  between  3ALN,  IQP,  and 
9ZN. 

Out  of  these  experiments'  an  interesting  fact 
emerged.  On  page  12,  of  the  March,  1923,  QST, 
Mr.  Kruse  stated  it  in  these  words: 

.  .  .  Why  all  these  logs?  For  this  reason  —  in 
every  single  test,  with  one  solitary  exception,  the  best 
signals  were  heard  at  some  wave  length  below  170 
meters.  Even  if  we  forget  all  about  the  decrea.sed 
interference  it  is  possible  for  us  to  move  downward, 
work  our  antennas  near  their  fundamentals  (or 
below)  and  get  better  signals  thru. 

The  early  settlers  have  found  the  region  of  100 
meters  good;  they  invite  the  amateur  world  as  a 
whole  to  come  along.   .   .   . 

As  a  first  step  toward  stimulating  general  ama- 
teur interest  in  the  wavelengths  around  100 
meters,  the  League's  Traffic  Manager,  F.  H. 
Schnell,  announced  "A  100- Meter  CQ-Party," 
for  the  nights  of  March  24th  and  25th,  1923.  (See 
Vohmie  VI,  at  12  to  13,  March  1923.)  In  addi- 
tion, the  following  announcement  was  made  by 
that  official  (see  13,  March  1923,  in  Volume  VI): 

"...  We  are  planning  a  system  of  short-wave 
test  stations  which  will,  at  the  same  day  and  hour  of 
each  week,  start  at  200  meters  and  send  tests  down 
to  100  meters  or  lower.  The  schedule  is  not  ready 
but  will  be  broadcast  on  200  meters  on  March  3rd 
and  10th  by  picked  ARRL  stations  in  each  district, 
(^Continued  on  page  1^4) 


'  Mr.  K.  B.  Warner  interjected  a  somewhat  critical  note, 
re  some  of  the  experiments  conducted  by  amateurs  on 
waves  between  80  and  135  meters,  during  the  winter  of 
1922-1923.  On  this  see  his  editorial,  "A  New  Field,"  at  29 
to  30,  March  1923  (Volume  VI).  Here  he  said: 

.  .  .  Last  winter  considerable  work  on  waves  between 
80  and  135  meters  was  done  between  some  amateur  stations 
in  Boston,  Hartford,  and  Pittsburgh,  hul  the  data  seems  to 
have  become  commercially  interesling  and  the  fellows  in  pos- 
session of  it  have  shut  up  like  clams  and  there  is  slight  hope 
that  those  particular  results  will  ever  become  available  to  us. 
As  a  result  some  of  our  own  gang  have  determined  to  dig  up 
the  dope  for  themselves  and  the  preliminary  tests  have  been 
most  encouraging.  .  .  .  [Italics  added  by  S.B.Y.] 


In  the  next  paragraph  of  the  same  Editorial,  Mr.  Warner 
pointed  out  the  freedom  from  interference  which  users  of 
100-meter  waves  were  enjoying,  and  then  referred  to  the 
added  "bonus"  of  appreciable  increase  in  radiation  effi- 
ciency which  had  been  experienced  when  the  wavelength 
was  shortened : 

.  .  .  Do  you  know  that  100-meter  transmission  between 
Illinois  and  Connecticut  is  proving  F.B.?  It  is!  At  the 
present  time  there  is  of  course  practically  no  QRM  on  such 
wave  lengths  except  an  occasional  harmonic.  That  alone 
makes  it  worth  while.  There  seems  to  be  an  appreciable  in- 
crease in  the  efficiency  of  radiation  as  the  tvave  length  is 
dropped:  and  there  is  the  'kick'  the  experimenter  gets  in 
trying  something  new  —  and  succeeding.  .  .  .  [Itahcs  added

KA  STATIONS 

APO  343 

San  Francisco,  Calif. 
Editor,  QST: 

It  has  recently  occurred  to  me  that  much  misinformation 
exists  regarding  operation  of  amateur  radio  stations  in  the 
Far  East.  I  am  therefore  taking  the  litjerty  of  writing  this 
letter  in  an  effort  to  outline  the  operation  of  amateur  radio 
stations  by  members  of  the  United  States  Forces  stationed 
in  the  Far  East  Command. 

As  you  undoubtedly  know,  immediately  subsequent  to 
cessation  of  hostilities  in  this  theater,  operation  of  amateur 
radio  stations  in  .Japan  and  other  portions  of  the  theater  was 
authorized  by  the  Supreme  Commander.  These  stations 
oi)erated  with  the  call  sign  prefix  normally  used  by  citizens 
of  Japan  (J.\).  When  sovereign  rights  were  restored  to  the 
Government  of  Japan,  however,  it  was  necessary  that  defi- 
nite agreements  between  the  United  States  and  Japan  be 
executed.  The  specific  agreement  which  permits  operation 
in  the  amateur  bands  in  Japan  is  outlined  in  the  Telecom- 
munications-Electronics .\greement  supplementing  the  .Ad- 
ministrative -Agreement  under  .Article  III  of  the  Security 
Treaty  between  the  United  States  and  Japan. 

It  was  agreed  that  the  terms  "amateur,"  "license,"  and 
"licensee"  would  not  be  used  in  describing  privately  owned 
stations  operating  in  the  amateur  bands  in  .Japan.  These 
stations  were  known,  instead,  as  .Auxiliary  Military  Radio 
Stations  (.AiMRS),  and  such  stations  were  to  operate  with 
the  call  sign  prefix  "KA"  rather  than  the  "JA"  previously 
authorized. 

Operation  of  tlie  amateur  radio  stations  was  to  be  regu- 
lated by  such  regulations  and  directives  issued  by  the  Com- 
mander in  Chief,  Far  East,  or  his  successor,  as  were  retjuircd 
for  orderly  operation.  One  of  the  stipulations  in  thi.s  agree- 
ment was  that  Far  East  Command  regulations  would  be  in 
consonance  with  the  Japanese  rules  and  regulations  govern- 
ing their  own  amateur  service.  Specifically,  the  difference 
between  the  Jaiianese  laws  and  tliose  laws  which  govern 
operation  of  amateur  radio  stations  in  the  United  States 
were  not  very  great.  Up  until  recently,  amateur  radio  sta- 
tions ojierating  in  Japan  operated  under  rules  and  regula- 
tions very  similar  to  those  of  the  Federal  Comnnmications 
Commission.  Approximately  eleven  months  ago,  however, 
the  Japanese  Government  pointed  out  that  Japanese  Xa- 
rjonal  amateurs  are  prohibited  from  handling  third-party 
traffic;  and  since  the  United  States  had  agreed  to  issue  such 
rules  and  regulations  as  would  be  in  consonance  with  the 
Japanese  laws,  the  Japanese  Government  requested  the 
Commander  in  Chief,  Far  East,  to  issue  the  necessary  di- 
rective proliibiting  the  handling  of  third-party  traffic  by 
United  States  Forces  personnel  operating  in  Japan.  .Also, 
since  Japanese  law  states  that  only  the  licensed  operator 
of  a  station  may  operate  the  station,  the  United  States  was 
requested  to  prohibit  the  privilege  of  a  non-licensed  indi- 
vidual speaking  over  the  microphone  of  an  .AMRS  station. 

Discussion  and  study  of  this  proposal  took  some  eleven 
months  to  eomiilete.  It  was  finally  agreed,  however,  that  the 
Japanese  request  was  valid,  inasmuch  as  the  agreement 
specified  above  clearly  stipulated  that  operation  of  United 
States  Forces  .AMRS  stations  would  be  in  consonance  with 
operation  of  Japanese  National  amateur  stations.  It  was 
therefore  agreed  that  the  United  States  would  issue  such 
directives  as  would  be  required  to  prohibit  the  handling  of 
third  party  traffic  by  -AMRS  stations  located  in  Japan, 
Since  the  agreement  specified  above  did  not  include  any 
territory  outside  of  the  Japan  limits,  operation  of  amateur 
stations  in  Okinawa  was  unaffected. 

I  have  no  doubt  that  some  word  of  the  third-party  traffic 
prohibition  has  reached  you,  and  I  expect  that  some  of  the 
information  you  may  have  received  has  been  garbled.  I  hope 
that  I  have  been  able  to  outline  the  present  conditions  under 


which  members  of  the  United  States  .Army  Forces  are  able  to 
enjoy  their  amateur  ijrivileges  in  this  country,  and  hope  that 
you  may  be  able  to  afford  some  publicity  to  the  capabilities

Thanks  to  WGTKA  (June  QST).  He  has  presented  a  \-iew- 
point  concerning  the  Larson  E.  Rapp,  WIOU,  articles  in 
which  I  concur.  Be  assured  this  is  also  the  opinion  of  more 
of  your  readers  than  you  may  susjject. 

Down  with  Rapp  —  there's  already  enough  "-April

-All  this  fuss  over  the  article  in  the  April,  1955,  issue  of 
QST  has  me  worried.  If  tills  man's  article  is  not  true,  does 
this  mean  that  his  other  articles  were  not  true,  also? 

I'm  only  a  beginner  at  radio  now  (6  months),  and  about  3 
months  ago  I  was  given  past  issues  of  QST.  Naturally  I  read 
them  by  the  hours,  trjnng  to  learn  as  much  as  I  could.  But  it 
just  occurred  to  me  that  the  article  "The  Double-Spectrum 
Theorem  "  (QST,  -April,  1952)  probably  is  not  true.  If  it  was, 
why  aren't  we  using  it?  .An  article  appears  in  every  -April

fuse people.

The  letters  in  June  QST  about  your  Rapp  articles  are 
enough  to  make  one  bury  his  head  in  his  hands  and  cry  like  a

these  indicate.  Here's  a  vote  for  maintaining  your  work  as

New  Term  for  the  YLRL 

The  new  officers  of  the  Young  Ladies  Radio 
League  assumed  their  duties  July  1st  and  will 
serve  an  18-month  term  in  order  to  put  the  club 
on  a  calendar  year  starting  January  1,  1957. 

President  of  the  YLRL  for  1955  and  '56  is 
Alice  "Cris"  Bowlin,  W9L0Y,  of  Chicago,  111.; 
YLRL  chairman  for  the  ninth  district  last  year. 
Cris  is  one  of  the  founders  and  a  past-president 
of  the  LARK  of  Chicago.  \Vith  her  OM,  W9RQF, 
she  operates  on  40  and  75  'phone. 

Last  year's  publicity  chairman  became  the 
V.P.  for  the  new  term.  Also  a  past-president  of

interests  of  amateur  radio  in  general.  Organized  in 
1939  by  Ethel  Smith,  W3IMSU  (then  W7FWB), 
the  current  membership  is  close  to  six  hundred. 
Any  Hcensed  woman  amateur  may  join. 

During  the  past  term  the  club  constitution  and 
by-laws  were  revised  for  the  second  time  (first 
revision  in  1948).  A  second  edition  of  the  YLRL 
Directory  was  edited  by  Lenore  Conn,  W6XAZ, 
and  the  first  YLRL  International  Convention 
was  sponsored  by  the  Los  Angeles  Young  Ladies 
Radio  Club. 

The  YLRL  conducts  two  major  contests  an- 
nually —  the  YLRL  Anniversary  Party  and  the 
YL-6m  Contest.  It  also  conducts  weekly  nets 
on  several  bands.  The  net  schedule  for  the  new 
term  will  be  published  in  this  department. 

YL  Harmonics,  a  publication  issued  bi-monthly 
by  the  organization,  gives  the  membership  cover- 
age of  club  activities  and  news. 

There  are  three  YLRL  awards  available  to  any 
licensed  amateiu-  —  ^Vorked  All  States-YL,  YL

PROTECTION  FOR  VOLT-OHM- 
MILLIAMMETERS 

MANY  of  US  who  make  frequent  use  of  a  general- 
purpose  test  meter  will,  at  one  time  or  an- 
other, inadvertently  apply  voltage  to  the  ter- 
minals of  an  instrument  having  the  function  or 
selector  switch  set  at  the  ohms  jiosition.  This  act 
of  negligence  may  result  in  a  burnt-out  multiplier 
shunt,  a  new  configuration  for  the  pointer  or  even 
more  serious  damage  to  the  meter  movement. 

The  installation  of  a  fuse  as  a  preventive 
measure  against  this  mistieatment  of  a  meter  is 
not  always  desirable  or  completely  effective.  The 
resistance  of  low-current  fuses  may  not  be  too 
uniform  and,  in  some  cases,  the  resistance  — 
whatever  it  happens  to  be  —  is  great  enough  to 
affect  the  calibration  of  the  ohiii-'i  ranges  of  the 
instrument. 

A  more  positive  protection  for  a  meter  may  be 
obtained  by  connecting  a  No.  14  flashlight  lamp 
in  series  with  the  internal  shunts.  It  has  been 
determined  that  the  resistance  of  these  2.5-volt 
0.3-amp.  bulbs  checks  consistently  at  very  close 
to  one  ohm.  Therefore,  once  the  .meter  circuit  has 
been  modified  to  include  a  bulb,  it  is  possible  to 
make  replacements  in  event  of  failure  without 
concern  over  variations  in  calibration. 

Fig.  1  shows  how  a  No.  14  bulb  has  been  con- 
nected into  a  typical  general-purpose  test  meter. 


out  even  before  the  pointer  can  deflect  to  full 
scale.  It  should  be  pointed  out  that  all  resistance 
ranges  of  a  circuit  of  the  type  shown  are  pro- 
tected by  this  simple  installation.

IMPROVED  BLEEDER  CIRCUIT 

THE  arrangement  shown  in  Fig.  2  provides  a 
warning  before  the  bleeder  resistance  burns 
out,  and  also  a  voltmeter  for  the  output  of  a 
power  supijl>'. 

The  normal  bleeder  resistance  is  made  up  of 
two   branches   in   parallel,   each   Ijranch  having

The  circuit  and  constants  shown  are  for  the 
poi)ular  Simpson  type  200  meter.  The  1-ohm 
resistance  of  the  bull)  is  compensated  for  by  re- 
moving approximately  2  inches  of  resistance  wire 
from  the  11.5-ohm  shunt  (/^i6  of  the  Simpson 
circuit).  Usually,  it  is  possible  to  find  mounting 
space  within  the  meter  case  for  a  socket  for  the 
bulb.  This  method  of  installation  simplifies  the 
changing  of  a  burnt-out  lamp. 

Any  voltage  applied  to  the  ohms  terminals 
that  is  lower  than  the  burn-out  rating  of  the 
bulb  will  not  cause  damage;  to  the  meter  shunts. 
At  higher  values  of  voltage,  the  bulb  will  burn

twice  the  resistance  of  the  normal  bleeder.  A 
milliammeter  connected  in  the  common  negative 
leads  reads  the  normal  bleeder  current.  If  one 
branch  of  the  bleeder  opens  up,  the  other  branch 
will  still  discharge  the  filter  condensers,  but  the 
meter  reading  will  fall  to  half  its  original 
value,  warning  the  operator  that  one 
branch  has  burned  out  and  should  be 
replaced  as  soon  as  possible. 

If  the  branches  are  made  of  equal 
resistance,  each  branch  of  the  bleeder 
can  have  half  the  power  rating  of  the 
normal  bleeder.  If,  for  example,  the  nor- 
mal bleeder  resistance  is  25,000  ohms, 
50  watts,  each  branch  can  be  50,000 
ohms,  25  watts. 

The  output  voltage  of  the  supply  can, 
of  coui'se,  be  determined  easily  by  multi- 
plying the  current  indicated  by  the 
milliammeter  and  the  bleeder  resistance  in  series 
with  it.  When  the  branches  are  equal,  this  re- 
sistance will  be  half  the  resistance  of  either  branch. 
Any  milliammeter  \\'ill  read  directly  in  voltage 
if  the  bleeder  resistance  is  10,000  ohms,  or  100,000 
ohms,  the  voltage  being  10  or  100  times,  re- 
spectively, the  reading  in  milliamperes.  A  25-ma. 
meter,  for  instance,  will  read  250  volts  full  scale 
with  a  l(),0()0-ohm  bleeder,  or  2500  volts  wdth  a 
100,000-ohm  bleeder.

CONDUCTED  BY  EDWARD  P.  TILTON,  WIHDQ 


THERE  are  some  300  logs  from  the  June  V.H.F. 
Party  already  in  the  Communications  De- 
partment files  as  we  write,  and  with  the 
reporting  deadline  still  several  days  away  more 
are  arriving  in  every  mail.  A  nationwide  picture 
cannot  be  drawn  at  this  time,  so  we  will  not  at- 
tempt it  until  next  moTith,  but  one  thing  is  cer- 
tain: the  f)-meter  band  has  staged  a  remarkable 
comeback.  For  the  first  time  in  several  years,  the 
downward  trend  of  6-meter  participation  in  our 
contests  has  been  reversed  —  and  decisively. 

Scattered  through  the  correspondence  accom- 
panying the  logs  are  frequent  comments  like 
"Sure  glad  to  see  the  activity  picking  up  on  6 
again!"  "Reminds  me  of  '46,  '47  and  '48!" 
"Made  91  contacts  on  6  this  time,  compared  to 
an  average  of  40  in  previous  contests." 

Obviously,  the  opening  of  the  50-Mc.  band  to 
Technician  licensees  couldn't  have  come 
at  a  more  opportune  time.  The  Ai)ril 
12th  deadline  gave  the  newcomers  a 
running  start  on  the  1955  sporadic-fi' 
DX  season  and,  perhaps  even  more  im- 
portant, the  knowledge  that  there 
would  be  some  new  calls  on  the  band 
to  work  flushed  out  no  small  number 
of  the  old  timers  who  used  to  be  on  6, 
but  have  not  bothered  to  get  on 
recently. 

Many  fellows  write  that,  for  the  first 
time  in  several  years,  they  can  now 
find  something  doing  on  6  any  evening, 
and  occasionally  during  the  daytime 
hours,  too.  It's  certainly  true  in  New 
England;  we're  not  overwhelmed  with 
QRM,  by  any  means,  but  you  can  make 
casual  contacts  once  again.  When  the 
band  is  open,  states  are  heard  that  have 
been  missing  for  the  past  two  or  three 
seasons.  No  longer  is  operation  confined 
to  the  one  "net  night"  each  week. 

This  is  all  to  the  good,  for  6  is  too  fine 
a  territory  to  lie  unused,  DX  season 
or  any  other  time.  Simple  converters, 


The  biggest  2-meter  antenna? 
W7LHL,  Seattle,  Washington,  has 
96  elements.  Each  bay  of  this  gi- 
gantic structure  has  two  half  waves  in 
phase,  with  reflectors  and  directors. 
With  a  high-powered  c.w.  rig  and  a 
low-noise  converter,  W7LHL  is 
loaded  for  bear. 


moderately-sized  antenna  systems,  and  trans- 
mitters that  won't  ruin  the  family  budget  provide 
consistent  coverage  that  could  easily  take  over 
much  of  the  burden  now  carried  by  lower  bands. 
Thousands  of  hams  now  knocking  each  other  out 
(or  trying  to)  in  the  turmoil  between  3800  and 
4000  kc.  could  work  over  much  of  the  same 
territory  on  50  Mc.  with  a  fraction  of  the  power 
—  and  no  strife. 

The  6-meter  band  is  20  times  as  wide  as  the 
75-meter  'phone  band,  and  as  good  or  better,  for 
distances  up  to  at  least  100  miles.  On  6  you  can 
use  any  mode  of  operation  you  like  —  c.w.  a.m., 
f.m.,  teletype,  s.s.b.,  duplex  —  with  little  or  no 
worry  about  stepi)ing  on  anyone  else's  toes.  The 
static  level  is  low  most  of  the  summer,  and  an 
ionospheric  disturbance  means  DX,  not  a  washed- 
out  band.

The  TVI  threat,  once  considered  an  insur- 
mountable obstacle  in  Channel  2  areas,  is  being 
licked.  There  are  many  ways  to  do  it.  W2IDZ 
showed  some  of  them  in  Jiuie  and  July,  1954, 
QST,  and  the  considerable  nightly  6-meter  activ- 
ity now  observed  in  Northern  New  Jersey  is 
evidence  that  he  knew  what  he  was  talking  about. 
As  far  as  the  other  channels  are  concerned, 
eliminating  TVI  with  a  6-meter  rig  is  no  more  of 
a  problem  than  it  is  on  any  other  ham  band;  in 
most  cases  it's  easier  on  6.  A  50-Mc.  "TVI 
Special"  is  undergoing  final  tests  in  the  ARRL 
Lab,  as  we  write.  It  will  deliver  a  clean  and  husky 
40  watts,  and  you'll  not  find  it  difficult  or  expen- 
sive to  build. 

The  series  of  articles  for  the  beginner  just  con- 
cluded in  last  month's  QST,  and  many  other 
QST  features  now  on  the  way,  will  help  the  cause 
along.  If  you're  the  type  that  refuses  to  build  his 
own  gear,  at  long  last  some  of  our  more  enterpris- 
ing manufacturers  are  bringing  out  some  real 
6-meter  equipment.  If  you've  always  been  going 
to  give  6  a  whirl,  there'll  never  be  a  better  time 
than  now  to  get  about  it.  Could  be  you'll  like  it! 

W2UK  Closes  Down 

To  do  an  outstanding  .job  in  any  phase  of  amateur  radio 
requires  a  combination  of  tlie  best  in  equipment  and  skill  in 
operating  that  comes  only  from  experience.  Some  of  us  have 
one  of  these  attributes,  but  we  miss  the  upper  brackets  of 
achievement  in  our  chosen  fields  of  endeavor  for  the  lack  of 
the  other.  This  is  no  less  true  in  v.h.f.  work  then  in  other 
kinds  of  hamming.  A  fellow  who  has  ranked  high  in  DX 
work,  for  instance,  is  likely  to  make  a  pretty  good  v.h.f. 
man,  if  he  is  thoroughly  bitten  by  the  bug.  At  least  one  did. 

The  thrill  of  working  in  a  fast-developing  branch  of  the 
art  caught  the  fancy  of  Ralph  E.  Thomas,  W2UK,  back  in 
the  early  '30s.  DX  men  of  the  prewar  era  don't  need  to  have 
his  record  recounted,  but  some  of  today's  DX  enthusiasts 
might  be  interested  to  see  what  one  of  the  country's  leading 
v.h.f.  operators  did  before  he  began  to  burn  up*the  2-meter 
band. 


We've  just  come  out  from  under  a  pile  of  old  QSTs  with 
the  following  record  of  DX  Contest  participation  by 
W2UK.  In  the  first  contest  in  which  there  was  a  scoring 
system,  back  in  1933,  W2UK  placed  third  in  the  N.Y.C  - 
L.I.  section  in  a  field  of  about  30.  In  1934  he  rated  14th  in 
the  country,  second  in  his  ARRL  section.  The  year  193.5 
found  W2UK  up  to  5th  in  the  U.S.  standing,  with  his  coun- 
tries total  third  in  the  nation.  By  1936  Tommy  was  the  top 
W2,  landing  in  3rd  place  in  the  national  ranking.  In  1937  he 
posted  the  country's  top  score  in  the  c.w.  competition  and 
set  a  new  countries- worked  record  with  71.  His  station, 
operated  by  another  v.h.f.  man  to  be,  W2HNY,  also  made 
the  top  W2  score  on  'phone.  First  place  again,  and  another 
country  record,  76,  were  achieved  in  1938.  The  last  DX 
contest  of  the  prewar  period  found  W2UK  in  third  place 
nationally,  just  a  whisker  behind  the  two  leaders,  with  80 
countries  worked. 

With  this  background,  it  is  easy  to  see  that  W2UK  was 
a  sure  bet  to  make  his  mark  in  v.h.f.  work,  once  he  tired  of 
what  he  now  calls  the  "d.c.  bands."  Tommy  started  in  on 
144  Mc.  about  five  years  ago  with  equipment  not  unlike 
that  used  by  most  2-meter  operators,  then  and  now.  His 
first  2-meter  antenna  was  a  5-over-5,  and  his  transmitter 
ran  about  100  watts.  He  was  just  getting  his  feet  wet  tak- 
ing a  sampling  to  see  if  the  2-meter  water  was  as  fine  as  had 
been  reported  by  some  of  his  ham  friends  who  were  already 
in  all  over. 

It  was!  Extended-range  communication  on  a  regular 
day-to-day  basis  was  just  getting  under  way  on  144  Mc, 
and  it  appeared  to  W2UK,  as  to  many  of  us,  that  pushing 
transmitter,  receiver  and  antenna  techniques  to  the  limit 
would  be  bound  to  produce  communication  over  distances 
then  believed  impossible  on  frequencies  where  ionospheric 
reflections  were  not  involved.  Before  long  the  rig  at  New 
Brunswick,  N.  J.,  had  been  upped  to  a  full  kilowatt,  and 
the  antenna  increased  to  40  elements.  Using  c.w.  mostly, 
and  working  in  conjunction  with  W2AZL,  W2NLY  and 
others.  Tommy  was  soon  keeping  reliable  schedules  on  2  at 
distances  up  to  nearly  500  miles.  His  record  of  consistent 
schedules  with  W20RI  and  W8WXV  has  never  been 
equaled.  And  when  the  band  was  open,  W2UK  had  a  signal 
by  which  all  other  eastern  stations  were  judged.  By  1953, 
W2UK  had  assumed  leadership  of  the  W2s  in  states  worked 
on  144  Mc,  a  position  he  shares  today  with  two  others. 

In  June  of  1953,  W2UK  began  what  turned  out  to  be  one 
of  the  outstanding  amateur  projects  of  a  v.h.f.  nature  of  all 
time,  the  observation  and  recording  of  meteor-scatter  signals 
on  144  Mc.  Working  with  W4HHK,  CoUierville,  Tenn.,  he 
spent  literally  hundreds  of  hours  keeping  schedules  at  all 
hours  of  the  day  and  night.  This  work,  reported  in  detail 
in  October,  1954,  QST,  resulted  in  widespread  attention 
of  the  most  favorable  sort  being  focused  on  amateur  radio. 

In  the  course  of  their  daily  schedules,  W4HHK  and 
W2UK  proved  that  meteor-reflected  signals  from  distances 
of  1000  miles  or  more  could  be  detected  consistently,  with 
the  duration  of  signal  bursts  occasionally  reaching  propor- 
tions that  permitted  the  exchange  of  useful  information. 
Thus  was  opened  to  v.h.f.  men  a  wholly  new  means  of 
making  distant  contacts. 

The  W4HHK-W2UK  schedules  came  to  a  close  June 
5th,  after  exactly  two  years  of  the  most  intensive  kind  of 
work  it  has  been  our  pleasure  to  report.  The  June  V.H.F. 
Party  was  W2UK's  closing  fling.  Though  busy  preparing 


One  of  the  reasons  for  the  out- 
standing 2-meter  signal  radiated  by 
W2UK  was  this  64-element  array 
atop  an  85-foot  pole.  Four  ]6-ele- 
nient  Yagis,  stacked  two  wave- 
lengths vertically  and  one  wave- 
length horizontally,  survived  hurri- 
cane winds  that  wrecked  many  lesser 
antenna  systems.  Another  2-meter 
array  at  W2UK  had  eight  5-eIement 
Yagis  spaced  one  wavelength  in  both 
dimensions,  four  bays  high  and  two 
wide. 


QST  for 


for  his  departure  for  KH6,  he  found  time  to  work  127  sta- 
tions in  19  ARRL  sections  on  144  Mc.  for  241.3  points.  This 
section  total  is  at  least  5  better  than  anyone  else  in  the 
country  was  able  to  do  on  144  Mc,  even  working  the  whole 
contest  period. 

The  famous  station  at  New  Brunswick  is  now  dismantled, 
but  much  of  it  is  on  the  way  to  Kahuku,  on  the  north- 
eastern side  of  Oahu  in  the  Hawaiian  Islands,  where  Tommy 
will  soon  be  taking  up  his  new  job  with  RCA  Communica- 
tions at  their  Kahuku  transmitting  station.  Two-meter 
signals  across  the  Pacific?  We  cannot  escape  the  feeling 
that,  if  the  job  is  to  be  done,  here  is  the  man  to  do  it.  One 
thing  seems  certain,  at  least:  2-meter  interest,  now  just 
gaining  a  foothold  in  KH6-land,  is  due  for  a  big  boost.  And 
while  v.h.f.  men  everj-where  will  feel  the  loss  of  W2UK. 
they  wait  expectantly  for  2-meter  developments  from  Ha- 
waii. Not  the  least  of  the  possibilities:  The  same  moon 
shines  on  both  KH6  and  W.  'Nuff  sed! 

National  V.H.F.  Calling  Channels? 

If  you've  done  much  mobile  work  on  the  v.h.f.  bands, 
you've  probably  tliought  many  times  liow  nice  it  would  be 
if  we  had  some  sort  of  national  calling  fretiviency  for  the  6- 
and  2-meter  bands.  There's  little  need  for  this  in  areas 
where  v.h.f.  activity  is  high,  but  it  would  be  convenient, 
when  traveling  in  the  hinterlands,  to  be  able  to  set  one's 
receiver  on  an  appointed  channel  and  be  sure  of  hearing  a 
signal  if  there  is  one  to  be  heard.  The  question  is  "What 
frequency?" 

There  was  some  attempt  in  the  heyday  of  the  RASO  work 
on  6  to  make  50.1  Mc.  a  national  calling  frequency.  There 
are  plenty  of  crystals  (8.3.50  kc.)  for  this  frequency  extant, 
and  it  gets  quite  a  play  when  the  band  is  open.  Trouble  is, 
no  channel  ever  seems  to  be  used  as  a  calling  frequency 
only,  even  on  lower  bands,  where  such  things  are  supposed 
to  be  standard  practice.  Would  v  h.f.  men  around  the  coun- 
try use  one  frequency  for  calling  and  another  for  carrj^ng 
on  a  contact,  once  made? 

We  doubt  it,  for  long  experience  in  such  matters  shows 
that  only  a  very  few  ever  know  that  the  arrangement  exists. 
Still,  there's  no  harm  in  tr>^ng.  Let's  make  it  50.1  Mc.  for 
calling,  unless  someone  has  a  better  suggestion.  (It  would 
help  if  the  "beacon"  stations  would  scatter  around  a  bit.) 
What  will  it  be  in  the  2-meter  band?  Offhand,  we'd  suggest 
144.6  Mc.  This  is  a  popular  surplus-crystal  spot,  and  out  of 
the  low-edge  QRM  area.  Can  anyone  suggest  a  better 
channel?  Thanks  to  W6BCX  for  bringing  the  matter  up. 

Here  and  There  on  the  V.H.F.  Bands 

Expedition  news  that  just  missed  last  month's  column: 
On  May  28th,  W6LIT  and  W6UID  joined  forces  to  provide 
Utah  contacts  on  144  Mc.  for  several  W6s  and  W7s.  They 
tried  to  reach  Brianhead  Mountain,  an  n,315-foot  eleva- 
tion, but  the  road  was  still  snowed  in,  so  they  had  to  settle 
for  Zion  Canyon  View.  This  is  a  9500-foot  spot  18  miles 
east  of  Cedar  City,  Utah,  and  45  miles  north  of  the  Utah- 


Arizona  border.  Equipment  was  a  3E29  final  stage,  running 
130  watts  input  on  c.w.,  a  crystal-controlled  converter  and 
BC-348  receiver,  and  an  8-element  (W6GD  type)  horizontal 
array.  Power  was  supplied  by  a  gas-engine  generator.  Sta- 
tions worked  included  W7VMP,  Phoenix,  Ariz.,  300  miles, 
W7LEE,  Parker,  Ariz.,  250  miles,  and  W6WSQ/6,  12  miles 
from  his  home  in  Pasadena,  375  miles. 

The  following  morning  they  set  up  at  Castle  Cliff,  a 
3000-foot  elevation  about  7  miles  inside  tlie  Utah  bound- 
ary. Here  they  worked  W6DNG,  Compton.  Calif.,  about 
350  miles,  and  W6WSQ/6  again.  W6DNG  was  the  only 
home  station  worked  in  California,  yet  his  signal  peaked  S7. 
The  location  of  W6DNG  is  only  88  feet  above  sea  level. 
W6NLZ  was  heard,  but  contact  could  not  be  completed. 
Polarization  checks  were  made  with  W6WSQ/6,  with  no 
marked  difference  being  observed  between  horizontal  and 
vertical.  A  final  stop  at  Wilson  Pass,  Nev.,  and  several  W6 
contacts,  completed  the  week  end's  work. 

The  W7VMP  schedules,  reported  in  May  QST,  have  been 
kept  regularly,  but  without  significant  results  except  wHth 
W5FAG,  Albuquerque,  N.  Mex.,  and  W6WSQ.  These  are 
mountainous  paths  of  about  350  miles,  in  nearly  opposite 
directions  from  Phoenix.  W5FAG  is  heard  on  nearly  every 
try,  though  two-way  contacts  have  not  been  made  regu- 
larly. W6WSQ  is  worked  consistently,  with  barely-audible 
c.w.  signals.  Indications  are  that  this  path  can  be  covered 
at  just  about  any  time,  when  high  power,  good  receivers, 
large  antennas  and  c.w.  are  employed.  There  are  few 
rougher  paths  of  3.50  miles  anywhere. 

Perhaps  the  most  pretentious  v.h.f.  expedition  of  all  was 
just  beginning  to  pay  off  as  we  write.  W2QCY/7,  complete 
with  panel  truck,  a.c.  generator,  45  watts  output  on  50 
Mc,  converter,  receiver  and  beam  antenna  (not  to  mention 
low-frequency  gear  for  liaison)  was  set  up  and  ready  for 
business  at  Wendover,  Utah.  June  22nd.  Wendover  being 
only  3  miles  from  the  Nevada  border,  plans  are  to  operate 
in  both  these  rare  states  when  the  band  is  open.  This  trip 
of  several  thousand  miles,  months  in  the  preparation  stages, 
was  made  expressly  for  the  purpose  of  providing  eastern 
6-meter  men  with  a  chance  at  Utah  and  Nevada,  the  two 
states  now  needed  by  just  about  everyone  who  lives  east  of 
the  single-hop  range. 

The  traditional  late-June  double-hop  sessions  produced 
hundreds  of  contacts  for  W2QCY/7,  and  for  a  similarly- 
e<iuipped  panel-truck  station,  W6ABN/7,  Las  Vegas, 
Nevada.  Stan  was  busy  for  hours  on  June  26th,  working 
Wis,  2s,  3s  and  4s  as  fast  as  he  could.  We  expect  a  flood  of 
50-Mc.  WAS  applications,  as  the  result  of  the  splendid  job 
these  two  crews  have  done  for  the  6-meter  gang.  Those 
Nevada  and  Utah  contacts  have  been  a  long  time 
coming! 

Interisland  2-meter  contacts  in  KH6  are  reported  by 
KH6AED,  Hawaii  SCM.  The  first  was  made  on  the  morning 
of  June  5th.  between  the  home  station  of  KH6AED  on 
Oahu,  and  KH6LD,  mobile,  on  Maui.  The  latter  was  atop 
Lookout  Point,  a  10,000-foot  elevation  at  the  top  of  Halea- 
kala,  the  volcano  crater  on  Maui. 


Ralph  E.  Thomas,  \r2UK, 
at  the  controls  of  his  2-meter 
station  at  New  Brunswick, 
N.  J.  Equipment  included  a 
144- Mc.  crystal-controlled 
converter,  working  into  a 
BC-342,  left,  for  quick  band- 
scanning,  or  into  an  SX-88 
for  weak -signal  DX  hunting. 
At  the  right  is  the  kilowatt 
rig  for  144  Mc.  Similar  shots 
of  ^  2L  K  can  be  found  in  the 
DX  Contest  write-ups  of  pre- 
war QSTs. 


August  1955

Odd-propagation  department:  \\'2ALR,  Lockport,  N.  Y., 
lieard  the  2-ineter  'iilione  signal  of  WIDXE,  West  Hartford, 
325  miles,  during  the  widesiiread  aurora  of  May  25th. 
There  was  only  a  sliglit  rumble  on  the  signal,  and  it  was  per- 
fectly readable.  This  was  about  8  p.m.,  when  the  c.w. 
signals  from  the  aurora  were  at  their  peak  strength.  There 
was  no  evidence  of  a  trojiosiiheric  opening  at  the  time.  Just 
a  few  nights  previously,  Larry  heard  a  pronounced  echo  on 
the  c.w.  signal  of  W2UK,  wiien  he  was  in  contact  with 
W20RI,  Lockport.  The  delay  was  estimated  at  50  milli- 
seconds. Question  is,  where  was  W2UK's  signal  going  to 
give  it  a  10,000-mile  echo? 

DX  cliancos  lost:  On  the  morning  of  June  5th,  your  con- 
ductor heard  the  50-iMc.  signal  of  W6ABN  for  a  jieriod  of 
an  hour  or  more,  rolling  in  about  as  well  as  we've  ever  heard 
a  West  Coast  signal  on  6.  WO.\BN  was  knocking  off  the 
W2s  and  3s  rapidly,  but  no  Wis.  How  widespread  the  skip 
was  at  that  time  is  seen  from  the  TV  DX  observations  of 
K6EDX,  Fresno,  Calif.,  for  the  same  period.  Bob  reports

that  between  0630  and  1430  PST  he  picked  up  Baltimore, 
Norfolk,  Va.,  Tulsa,  Philadelijhia,  Washington,  New  York, 
Chicago,  Montpelier,  Vt.,  Kansas  City,  Kalamazoo,  Mich., 
Rochester,  Great  Bend,  Kans.,  Omaha,  Green  Bay,  Wise, 
Wichita  Falls,  Texas,  Si)okane,  Wash.,  and  Great  Falls, 
Mont.,  on  TV  channels  2  through  5!  Si)oradic-£  skip  begins 
on  lower  frequencies,  and  goes  higher;  that  is,  the  50-Mc. 
band  is  open  before,  during,  and  after  the  TV  channels. 
There  was  quite  a  bit  of  DX  worked  on  6  at  that  period, 
but  the  stuff  on  the  TV  frequencies  gives  some  idea  of  what 
6  might  have  been  like  if  we  had  activity  over  the  country 
in  anything  approaching  75-meter  proportions! 

Horizontal  Antennas  for  2-Meter  Mobile 

In  open  country,  at  least,  it's  helpful  to  have  the  polariza- 
tion matched  between  mobile  and  fixed  stations.  The  general 
swing  to  horizontal  has  residted  in  scores  of  ideas  for  hori- 
zontal mobile  antennas.  W20W,  Vestal,  N.  Y.,  has  had  fine 
results  with  a  folded  dipole  taped  to  the  rear  window  of  his 
car.  This  can  be  fed  with  coax  through  a  bahm,  or  used 
with  a  balanced  line.  The  dipole  can  be  made  of  Twin-Lead, 
or  of  fine  w-ire,  the  latter  having  the  advantage  of  being 
almost  invisible  from  even  a  short  distance  away  from  the 
car. 

W9ULF,  Oak  Park,  111.,  has  a  demountable  set-up  that 
has  considerable  merit.  He  cut  a  piece  of  ?^-inch  copper 
tubing  one  foot  long,  and  bent  it  at  the  center  so  that  when 
the  lower  portion  is  parallel  to  the  door  jamb  of  his  car,  the 
upper  half  is  vertical.  Two  clips  of  thin  sheet  metal  hold  this 
tube  in  place,  with  self- tapping  screws  inserted  into  the 
door  jamb.  The  copper  tubing  can  be  chromium  plated,  or 
painted  to  match  the  car,  after  which  it  is  a  nearly  invisible 
socket  for  holding  a  removable  mobile  dipole. 

The  dipole  itself  consists  of  two  19-inch  stiff  wires,  in- 
serted in  a  triangular-shaped  block  of  polystyrene.  This 
mount  is  fitted  over  the  top  of  a  M-inch  aluminum  rod  19 
inches  long,  which  is  inserted  into  the  socket  when  mobile 
work  is  in  prospect.  The  dipole  is  fed  with  coax  directly.  A 
balun  was  tried,  but  with  the  short  run  of  coax  involved,  it 
made  no  practical  improvement  in  performance.  The  coax 
is  65  inches  long. 

If  there  is  a  tendency  to  rotation  of  ^he  dipole  when  the 
car  is  moving,  the  vertical  support  can  be  wrapped  in  fric- 
tion tape.  Pushing  it  down  in  the  socket  tightly  will  hold  it 
in  position  firmly. 

OES  Notes 

W2UTH,  Victor,  N.  Y.  —  Many  new-  stations  coming  on 
6,  some  at  the  expense  of  220  and  420  Mc. 

W30TC,  Silver  Spring,  Md.  —  Appearance  of  Techni- 
cians on  50  Mc.  is  the  best  thing  that's  happened  to  the 
band  in  many  a  year.  A  high  percentage  of  DX  stations 
worked  appear  to  be  newcomers,  and  activity  is  well  above 
recent  years. 

W4IKK,  Rome,  Ga.  —  Have  807  working  fine  as  straight- 
through  amplifier  on  50  Mc,  driven  by  12BH7  as  push-push 
dovibler.  A  pi  network  is  used  for  interstage  coujjling,  with 
a  20-nMf-  variable  capacitor  on  tlie  12BH7  end  of  the  coil 
and  a  40-^^1-  fixed  capacitor  at  the  807  grid.  The  coil  is  7 
turns,  >2-inch  diameter,  J^  inch  long.  The  807  is  mounted 
in  a  shield  made  from  a  small  can  of  the  frozen  fruit  juice 
variety.  No  socket  is  used,  contact  being  made  to  the  807 
with  pins  removed  from  an  old  wafer  socket.  The  cathode 
pin  and  one  heater  pin  are  soldered  to  the  can.  The  807 
plate  timing  capacitor  is  a  neutralizing  unit  from  a  BC-375. 
W'ith  the  tube  mounted  horizontally,  a  short  heavy  lead 
connects  from  the  capacitor  to  the  807  plate  cap,  and  the 
plate  coil  is  at  the  far  end  of  the  capacitor.  The  effectiveness 
of  the  by-pass  at  the  cold  end  of  the  807  plate  coil  was  im- 
proved by  enclosing  it  in  sheet  aluminum.  The  amplifier  is 
completely  stable  at  all  settings  of  the  tuning  controls,  and 
no  parasitic  chokes  are  needed.  It  runs  nicely  at  65  watts 
input,  with  6.50  volts  on  the  plate. 

W'ith  phase  modulation  most  Channel  2  TVI  that  de- 
veloped with  a.m.  is  cleared.  The  closest  receivers  can  be 
handled  nicely  with  a  W2IDZ  filter.  See  July,  1954,  QST, 
page  33,  for  details.

QST  for

Who's  Where: 

This  being  a  prime  vacation  month  we'll  dis- 
pense with  our  usual  abstruse  DXhortation  and 
choose  instead  to  help  beef  up  your  DX  reference 
library.  Avid  DXers  en  route  DXCC  haven't 
much  time  to  sit  around  indexing  their  QST  files 
and  questions  like  "Now  where  did  I  see  a  pic- 
ture of  FG7XB?"  often  arise.  So,  as  an  excerpt 
from  records  that  Jeeves  maintains  for  our  own 
convenience,  here's  a  taljulation  of  photography 
that  appeared  in  "How's  DX?"  over  the  past 
three  years  (asterisks  denote  equipment  only):

Here  are  the  guys  and  groups  that  were  good 
enough  to  entertain  you  by  the  loan  of  those  pix:

If,  as  the  Chinese  long  ago  put  it,  each  pic  is 
worth  more  than  10,000  words,  these  parties 
turned  in  plenty  of  DX  column  copy  during  those 
past  36  months.  Our  efforts  to  document  doings 
in  the  DX  world  are  greatly  enhanced  by  such 
cooperation.  A  special  salute  to  OT  contributors 
an  fait  W6YY  and  W8IV  who  helped  doll  up 
three  separate  DX  columns  since  July,  1952. 

Incidentally,  for  the  statistically  inclined,  it  is 
of  interest  to  note  that  a  check  with  the  ARRL 
DXCC  Countries  List  reveals  more  than  100 
countries  represented  in  the  preceding  photo 
index.  That's  a  fairly  fast  DXCC  for  your 
"How's"  picture  gallery! 

What: 

Time  was  when  July  and  August  were  one-band  months 
so  far  as  the  northern  latitudes  world  of  DX  is  concerned. 
The  band,  of  course,  was  20.  Thanks  to  the  happy  acquire- 
ment of  a  lo-nieter  band  and  an  assist  from  the  valley  of 
the  solar  cycle,  North  American  amateurs  now  get  hot- 
weather  DXercise  on  a  variety  of  frequencies.  Hop  on  our 
"How's"  Bandwagon  and  see  for  yourself,  OM,  bearing  m 
mind  that  in  the  text  to  follow,  frequencies  (given  m  number 
of  kc  above  the  lower  band-limit)  appear  m  parentheses, 
times  without.  E.g.,  (9)  =  14,009  kc,  if  the  paragraph 
deals  with  20-meter  work.  Times  are  GMT,  usmg  the  nearest 
whole-hour  figure  such  as  7  for  0720  or  0()50,  0  for  0015  or 
■^349  .A.S  a  rule  each  DX  call  is  mentioned  but  once  per  band.

An  IIT-9  rig  and  S\-71  inhaler  are  tlie  nucleus  of  the

Reference   the   QSL-VP7NX-via-VV8RVM   squib 

in  our  May  effort,  ex-W8RVM  (now  W4FIQ)  points  out 
that  this  is  true  only  for  about  300  QSOs  dating  between 
July,  1953,  through  January,  '54.  For  obscure  purposes  of 
bookkeeping  long  incomprehensible  to  Jeeves,  certain  li- 
censing authorities  deem  it  necessary  to  issue  almost  im- 
mediately a  given  call  sign  to  successively  different  holders. 
In  view  of  the  importance  of  amateur  radio's  QSL  tradition 
it  sliould  be  obvious  that  such  switching  of  call  signs  easily 
makes  for  confusion  and  the  possible  besmirching  of  inno- 
cent rei)utations.  Two  years  doesn't  seem  an  unreasonable 
length  of  time  for  a  second-hand  call  sign  to  lie  in  abeyance 
while  time  dissociates  it  from  the  identity  of  its  last  pre- 
vious  owner   ._._._    W4QCW    reconiuiends   that   those 

still  shy  ZC7DO  pasteboards  reapiily  to  G4CP 

Stamped  self-addressed  envelopes  are  refiuired  if  you  accept

rent QSL  matters  for  VROAC,  will  use  bureau  paths  unless 
applications  are  accompanied  by  s.s.a.  envelojies  ._._._ 
IIBNU  of  Trieste  advises  that  the  last  published  listing

Italian  licensing  revisions  are  being  completed.  Likewise, 
then,  for  stations  in  Sardinia  and  Italy  proper  ._._._ 
From  HZIAB:  "Our  QSL  situation  has  been  alleviated  by 
the  use  of  one  of  the  Mimeograph  machines  on  the  base.

through  the  bureaus.  As  soon  as  things  slow  down  a  bit, 
cards  will  be  sent  direct."  Incidentally,  HZIAB  makes  use 
of  U.  S.  postage.  Operator  WOCRV  awaits  reassignment

few  hams  in  Italy  because  of  the  new  regulations  issued 
last  year.  All  Italian  hams  have  had  to  sit  for  examinations 
on  theory  and  c.w.  in  order  to  get  their  old  ham  licenses 
renewed.  So  far  the  number  of  new  licensees  is  around  200; 
before  the  regulations  changes  there  were  4000  hams  in 
Italy."  Mario  intersperses  his  own  DX  work  on  80  through

G3.TFD,  via  NNRC's  Official  BuUetin,  clarifies  British  call- 
sign  arrangements.  "Firstly,  no  distinction  is  made  between 
the  various  prefi.\es  of  the  British  Isles  (G  GC  GD  GI  GM 
GW),  which  means  that  if  there  is  a  G3AA.\,  no  other 
British  prefix  can  be  followed  by  "3AAA"  unless  G3AAA 
moves  to  another  area.  Secondly,  the  numbers  in  British 
call  signs  have  no  territorial  significance  whatever."  GI  G7 
and  G9  calls  are  specials  used  by  experimental  stations  of 
various  kinds.  Tlie  GB  prefix  is  reserved  for  use  by  exhibi- 
tion stations  and  the  like.  Only  the  prefixes  G2  and  G3  at 
present  are  followed  by  three  letters,  these  being  call  signs 
issued  since  1945. 

South  America  —  From  South  Shetlander  VP8A: 
"There  will  only  be  four  VPS  stations  active  from  .Antarc- 
tica this  coming  year.  They  are  VP8BD  who  will  be  oper- 
ating from  Grahamland,  VP8s  AQ  BF  and  BH  who  will 
be  oi)erating  from  the  South  Shetlands.  There  is  a  faint 
possibility  that  a  VP8  will  be  active  from  my  old  location 
in  Soutli  Orkney  Islands  but  the  call  is  not  known  at  the 
moment.  The  VP8  stations  who  were  active  from  Antarc- 
tica during  1954  —  VP8s  AA  AO  AX  and  .\Z — already 
have,  or  will  have  in  the  near  future,  returned  to  England."

A  Test  for  Handling  Overseas  Traffic.  Reg- 
ulations prohiliit  the  handling  of  communications 
on  behalf  of  third  jjarties  internationally  by  ama- 
teur ladio,  except  where  special  arrangements 
have  been  made  between  nations.  Chapter  9  of 
the  ARRL  License  Manual  details  this  prohibi- 
tion (Article  42  of  the  Atlantic  City  documents). 
Our  operating  booklet  likewise  mentions  the  re- 
striction in  the  section  on  handling  messages. 
Third-party  traffic  under  certain  treaty  provi- 
sions and  limitations  is  authorized  between  the 
United  States  and  Canada,  Chile,  Cuba,  Ecua- 
dor, Liberia  and  Peru.  Traffic  may  be  freely  han- 
dled with  outlying  U.  S.  territories  and  posses- 
sions wherever  amateurs  are  licensed  by  the 
FCC,  as  well  as  with  the  Canal  Zone.  Message 
traffic  for  U.  S.  military  personnel  overseas  is  per- 
mitted only  with  amateur  stations  identified  by 
properly  authorized  call  signs  having  a  one  or  two 
letter  prefix  beginning  with  a  W  or  K. 

Traffic  of  an  unofficial  nature  that  comes  via 
MARS  or  on  a  military  instead  of  an  amateur 
frequency  is  sometimes  re-originated  or  re-filed  for 
handling  within  the  U.  S.  A.  as  an  amateur  radio- 
gram. Since  Germany  has  been  returned  to  the 
ranks  of  sovereign  nations  Article  42  is  again  ap- 
plical)le  and  traffic  on  amateur  bands  may  not  be 
handled  directly  with  DLs,  though  such  MARS 
re-files  are  perfectly  legitimate.  The  form  or  pro- 
cedure for  such  re- files  is  detailed  on  page  130, 
June  1953  QST. 

Limitations  Requested  on  Japanese  Traffic. 
The  P'ar  East  Auxiliary  Radio  League  is  the 
organization  of  the  KAs  in  Japan.  Pointing  out 
that  their  request  does  not  concern  MARS  pro- 
grams or  amateur  operation  in  other  than  their 
region,  the  FEARL  has  requested  KAs  and  those 
they  work  voluntarily  to  limit  third-party  traffic 
to  personal  problems  such  as  arrival  and  de- 
parture messages,  family  illness,  deaths,  assisting 
dependents  getting  ready  to  go  overseas,  etc., 
and  to  carry  out  a  reduction  in  third-party  traffic 
of  all  kinds.  The  removal  of  any  essential  traffic 
in  KA-land  from  their  amateur  'phone  bands  to- 
either  MARS  (military)  frequencies  or  c.w. 
transmission  and  limitation  of  all  'phone  patches 
to  cases  of  actual  need  is  urged  by  the  FEARL. 
Important  matters  of  finance  or  personal  busi- 
ness they  point  out  should  be  filed  by  commer- 
cial service  both  to  give  privacy  and  assured 
guaranteed  delivery.  It  is  also  re(}uested  that  any 
unnecessary  greeting,  etc.,  messages  that  unduly 
expand  the  volume  of  work  be  curtailed.  From 
the  data  released  by  FEARL  it  appears  that  quite 
I>robably  in  view  of  Japan's  resumption  of  licens-

ing  (sovereignty)  the  JARL  and  commercials 
operating  under  Japanese  Hcense  have  objected 
to  the  essential  character  of  some  of  the  commu- 
nications, doubtless  in  the  light  of  the  conflict 
with  treaty  provisions  (Art.  42)  as  above  men- 
tioned. 

P.A.R.E.C.  The  letters  stand  for  Portable 
Amateur  Radio  Equipment  Contest  and  recall  to 
mind  the  famous  Miles  Per  Watt  contest  of  the 
Twenties.  (u8GZ  using  'OlA's  and  199's  won  the 
Jewell  Contest;  on  40  meters  in  Jan.  and  Feb. 
'26  he  worked  oa6N  and  oz2XA  with  inputs  of 
14  watt,  something  to  try  on  VKs  and  ZLs  to- 
day!) The  Field  Day  challenges  our  ability  to 
"make  under  30  watts  count"  but  stand-by 
radio  provisions  for  civil  defense  are  far  from  ful- 
filled in  the  light  weight,  low-power  equipment 
categories.  The  need  for  amateur  hand-carried 
and  mobile  equipment,  packaged  for  results  with 
minimum  weight,  is  therefore  a  measured  objec- 
tive in  its  own  right  by  anybody's  say  so.  So  here's 
the  background  on  how  you  can  submit  some 
equipment  descriptions  to  a  specialist  group  offer- 
ing you  certificates  for  your  accomplishment  in 
this  constructional  field. 

To  increase  interest  in,  and  encourage  devel- 
opment of  Low  Power  and  portable  equipment  by 
radio  amateurs,  the  QRP  Society,  an  RSGB 
group,  is  running  a  constructional  competition 
not  to  close  until  September  30,  1955  known  as 
their  Portable  Amateur  Radio  Equipment  Con- 
test. This  is  open  to  all  licensed  amateurs  and 
SWLs  throughout  the  world  either  as  individuals 
or  in  club  teams.  Any  number  of  entries  may  be 
submitted,  though  the  equipment  itself  is  not  to 
be  shipped  overseas.  The  QRP  Society  will  give 
certificates  for  overseas  entry  descriptions  ad- 
judged best  with  its  contest  divided  into  four 
equipment-classes. 

Class  A  —  For  hand  carried  portable  receivers  (up  to  3 
pounds),  transmitters  up  to  5  pounds  and  transceivers  up  to 
7  pounds.  Must  be  dry  battery  operated,  weights  exclusive 
of  batteries,  phones,  key,  antenna.  Economy  of  battery  con- 
sumption, lightness,  compactness,  versatility  and  ease  of 
operation  will  be  considered. 

Class  B  —  For  mobile  transmitters,  receivers  or  trans- 
ceivers up  to  10  pounds  maximum  weight,  exclusive  of 
batteries  but  inclusive  of  vibrator  unit  as  necessary. 

Class  C  —  For  transistor  sets  up  to  2  pounds  weight  ex- 
clusive of  avixiliary  equipment. 

Class  D  —  For  portable  lesl  gear  of  any  type  such  as  wave- 
meters,  signal  generators,  etc.  All  must  be  amateur  built, 
battery  operated  and  truly  portable. 

A  special  certificate  will  be  issued  by  the  QRP 
Society  to  the  /*e.s/  three  American  entries  in  each 
class.  Submit  entries  before  September  30,  1955

DX  Club  Sets  High  Operating  Standards. 
The  ^'Southern  California  DXER  Award"  is  to 
be  an  engraved  plaque,  presented  annually  "for 
outstanding  performance  and  meritorious  achieve- 
ment in  amateur  radio  DX  work  among  Southern 
California  amateur  radio  operators."  W6MUR 
explains  that  the  first  presentation  by  the  South- 
ern California  DX  Club  will  be  at  the  joint  DX 
clubs'  meeting  in  Fresno  in  January,  1956. 
Nominations  will  be  received  by  the  club  in  the 
period  November  1st  to  December  loth.  The 
club  stresses  that  the  Southern  California  ama- 
teur who  is  the  winning  candidate  does  not 
necessarily  have  to  be  a  member  of  the  club.  A 
club  committee  will  be  charged  with  weighing 
some  of  the  following  factors  in  making  a  choice 
for  the  plaque  award.  In  the  following,  readers  we 
think,  \\-ill  appiove  of  the  importance  SCDXC 
has  given  in  its  listings  of  factors  to  the  promo- 
tion of  DX  success  in  terms  of  positive  operating 
courtesy  and  ability,  with  initiative  in  club  work 
as  well  as  in  operating.  The  last  item  (k )  spells 
out  that  the  man  with  most  power  and  ruthless- 
ness  does  not  necessarily  win !  The  group  consider- 
ing the  nominations  and  results  for  the  year  1955 
according  to  this  may  consider  DX  results  ob- 
tained contrasted  to  the  capabilities  of  the  sta- 
tion. How  well  an  amateur  performs  with  what  he 
has,  if  given  an  appropriate  weighing  by  the 
award  group,  could  give  a  Southern  California 
amateur  in  the  lowei  jiower  category  a  chance  at 
this  one!  Here  are  the  items  for  objective  rating 
of  all  possible  candidates: 

(a)  Operating  ethics  and  courtesy. 

(b)  Station  activity. 

(c)  Signal  quality. 

(d)  Observance  of  FCC  regulations. 

(e)  Contributions  to  Southern  California  DX:  participa- 
tion in  club  activities,  contests  and  functions;  attendance  at 
club  meetings;  bulletin  contributions,  technical  contribu- 
tions and  similar  factors. 

(f)  Contributions  to  amateur  radio:  helping  new  ama- 
teurs, or  foreign  amateurs  in  any  way  througli  expedition 
traffic,  loans  or  gifts  of  parts  or  equipment,  handling  or  sup- 
plying QSL  cards,  assistance  with  technical  problems,  etc. 

(g)  Attitude  toward  fellow  amateurs. 

(h)  Attitude  toward  the  public,  including  neighbors. 

(i)  Perseverance:  effort  in  listening  for  new  countries;  in 
obtaining  missing  QSL  cards;  in  striving  for  DX  goals  of 
various  sorts  such  as  certificates  or  awards;  in  ferreting  DX 
information. 

(i)  Operating  ability:  copjdng  through  noise  or  QRM; 
code  speed;  ability  to  cope  with  confusion,  etc. 

(k)  Success,  expressed  as  a  quahtative  ratio  of  DX 
worked  to  capabilities  of  station  —  how  well  an  amateur 
performs  with  what  he  lias. 

(1)  (m)  Other  factors  considered  applicable.

WlAW  OPERATING  NOTE 

A  slight  change  has  been  made  in  the  WlAW  General- 
Contact  schedule  effective  June  1st  (see  page  70,  May  QST). 
The  station  will  no  longer  listen  for  No\'ices  after  the  mid- 
night (EDST)  bulletins  on  355.5  kc.  Tuesday  and  7125  kc. 
Friday.  Instead,  WlAW  will  listen  for  Novices  after  the 
midnight  (EDST)  bulletins  on  .3.555  kc.  Wednesday  and 
7125  kc.  Saturday  (a.m.).  The  lithographed  WlAW  sched- 
ule now  available  on  request  shows  this  change. 

The  WlAW  operating  schedule  (page  74,  July  QST)  is 
still  in  effect. 

BRIEF 

In  the  Novice  Round-up  Results  (May  QST).  the  call  of 
the  Santa  Clara  Valley  leader  should  have  been  shown  as 
KN6EM0.  In  addition,  information  brought  to  our  atten- 
tion reveals  that  KN2IBII,  not  KN2ICU,  was  the  rightful 
winner  in  N.Y.C.-L.I.  section.

APRIL  30TH  RACES  TEST 

We  use  the  above  title  with  reservations.  There  seems  to 
have  been  some  question  as  to  whether  this  was  a  RACES 
test  or  an  "Amateur  Test  of  RACES  Potential."  The  latter 
is  probably  a  better  description  of  it,  but  it's  too  long  for  a 
title.  Actually,  the  test  included  AREC  organizations  in  all 
stages  of  RACES  preparation  as  well  as  those  already 
RACES-authorized  in  FCDA  Region  I. 

A  bit  of  background  will  be  pertinent.  As  long  ago  as  last 
October,  FCDA  by  official  letter  requested  ARRL  to  assist 
in  conducting  a  test  of  RACES  facilities  and  potential  in 
one  of  its  regions,  to  serve  as  a  monitor  or  "sounding  board," 
if  you  will,  for  the  nationwide  Operation  Alert  test  to  be 
conducted  in  June.  Naturally,  we  agreed  to  do  so  and 
alerted  our  ECs  in  Region  I  by  special  bulletin.  A  prelimi- 
nary meeting  was  held  in  West  Hartford  in  early  February 
to  discuss  plans  with  representatives  of  FCDA  and  others. 
In  late  March,  a  meeting  of  all  state  c.d.  radio  officers  and 
all  ARRL  SECs  in  the  region  was  held  in  New  York  to 
finalize  plans.  It  was  at  this  meeting  that  the  decision  was 
made  to  include  all  amateurs  working  in  civil  defense, 
whether  they  were  finally  authorized  for  RACES  or  not. 
Only  in  this  way  would  an  accurate  idea  of  RACES  potential 
be  obtained. 

As  it  turned  out,  not  all  RACES  authorized  groups  par- 
ticijjated  —  or  if  they  did,  they  didn't  tell  us  about  it.  We 
ran  two  surveys,  one  before  the  test  on  the  basis  of  those 
who  expected  to  participate,  and  one  after  the  test  on  the 
basis  of  those  who  actually  did  so.  Let's  compare  tliem 
briefly. 

A  total  of  122  ECs  made  preliminary  reports  on  their 
potential  for  the  April  .30th  Test.  Of  these,  only  48  reported 
actual  results;  however,  49  addiliotial  ECs,  Avho  did  not 
make  preliminary  reports,  also  reported  results,  making  a 
total  of  97  ECs  who  did  report  results.  Compared  to  the 
122  preliminary,  tliis  is  a  mighty  good  percentage.  To  be 
statistically  accurate,  however,  the  percentage  of  partic-' 
ipants  compared  to  the  number  who  expected  to  partici- 
pate was  .39.3%. 

A  comparison  of  expected  with  actual  participation  can 
best  be  summarized  in  the  following  table:

No  comment  is  needed  on  the  above  data.  They  speak 
for  themselves.  Naturally,  they  reflect  only  reports  re- 
ceived. We  have  no  notion  of  how  many  groups  who  said 
they  intended  to  participate  actually  did  so  but  didn't 
report  it  —  or  how  many  expected  to  and  did  take  part  but 
didn't  report  either  time.  These  are  just  some  of  the  im- 
ponderables about  this  business. 

A  brief  rundown  on  statistical  results  of  the  April  30th 
Test  and  we'll  be  done  with  them.  There  were  671  AREC 
registrants  participating,  89  non-amateur  operators  and 
113  non-AREC  amateurs  assisting.  Stations  used  consisted 
of  216  fixed  control  stations,  236  other  fixed  stations  and  233 
mobiles.  Most  of  the  mobiles  (62%)  operated  on  ten  meters, 
with  two  meters,  six  meters  and  7.5  meters  following  in  that 
order.  Forty-three  ECs  reported  that  CD  officials  were 
present  at  the  test,  36  that  they  were  not;  tlie  rest  did  not 
say.  Twenty-five  ECs  rated  non-RACES  CD  cooperation 
as  excellent,  fifteen  as  good,  seven  as  fair,  five  as  jioor,  two 
as  "lousy"  and  fourteen  said  cooperation  was  non-existent. 

Eastern  Massachusetts  section  ECs  contribiited  the 
greatest  number  of  reports  on  the  test  (18),  with  Connecti- 
cut second  (12),  Eastern  New  York  third  (11)  and  Western 
New  Yock  fourth  (10).  Western  New  York  had  the  greatest 
number  of  participating  operators  (192),  with  Eastern  New 
York  second  (1.59)  and  New  York  City-Long  Island  third 
(132).  In  mobiles,  Western  New  York  was  high  with  65, 
New  York  City-Long  Island  second  with  41,  and  Eastern 
New  York  third  witli  32. 

The  test  started  at  1530  and  lasted  until  2130  EST,  in 
order  to  get  the  best  j)ossible  cross-section  of  band  condi- 
tions during  daylight,  twilight  and  total  darkness.  Many  of 


the  participating  groups  kept  active  the  whole  period,  chang- 
ing "shifts"  every  two  hours  in  order  to  get  a  better  picture 
of  operating  requirements  in  the  real  thing.  Circuits  were 
kept  heavily  loaded  with  "canned"  messages  in  order 
closely  to  simulate  actual  emergency  operating  conditions. 

FCDA  sent  Jim  MacGregor,  W8DLTA,  into  Region  I  to 
observe  the  test  first  hand.  Jim  visited  the  New  York  State 
control  center  in  New  York  City,  then  in  the  company  of 
New  York  State  RACES  Radio  Officer  W2BG0,  he  jour- 
neyed into  Connecticut  for  a  visit  to  Connecticut  installa- 
tions and  ARRL  Headquarters. 

Our  count  of  ECs  in  FCDA  Region  I  is  440.  Ninety- 
seven  reporting  results  is  22%.  This  is  about  what  can  be 
expected  —  in  fact,  it's  better  than  most  of  our  previous 
reporting  records;  which  isn't  the  same  as  saying  it  is  good. 

The  record  does  not  do  justice  to  the  performance  of  the 
Rhode  Island  gang,  as  reported  by  SEC  WITQW.  Twenty 
recently-appointed  ECs  activated  communications  net- 
works in  16  major  cities  and  towns  throughout  the  state, 
with  200  amaterus  responding  to  the  call  —  about  one  third 
of  all  the  amateurs  in  the  state.  Each  of  the  16  nets,  con- 
sisting of  a  control  station  controlling  a  mobile  net,  main- 
tained contact  with  a  two-meter  substation  operating  at 
state  level.  Traffic  originated  in  any  locality  would  be  picked 
up  by  a  mobile,  transmitted  to  his  control,  passed  to  the 
state  station  and  relayed  into  state  headquarters  in  jig  time. 
A  total  of  307  messages  were  routed  to  state  control  in 
Scituate  by  this  method. 

Termed  a  success  in  glowing  phrases  in  Rliode  Island, 
the  April  30th  Test  was  described  less  enthusiastically 
in  other  states  in  the  region.  The  statistics  show  that  a 
good  showing  was  made  in  New  York,  as  was  to  be  ex- 
pected of  a  well-organized  state  RACES  establishment. 
Statistics  fail  to  do  justice,  however,  to  the  showing  in 
Northern  New  Jersey,  which  was  better  than  indicated. 
Connecticut  maintained  its  standard  as  a  pace-setter  for 
RACES  organization,  although  there  was  some  misunder- 
standing concerning  eligibility  to  participate  which  kept 
attendance  down.  This  same  misunderstanding  occurred  in 
Massachusetts,  another  well-organized  state  from  the  c.d. 
angle.  The  remaining  states  participated  at  about  the  ex- 
pected level. 

It  is  easy  enough  to  be  mealy-mouthed  and  say  the  test 
was  an  "overall  success."  Actually,  whether  or  not  it  was 
so  is  a  matter  of  individual  opinion  —  and  we  have  heard 
opinions  variously  from  "complete  flop"  to  "indeed  a  suc- 
cessful demonstration."  Looking  at  it  from  an  overall  view- 
point, which  probably  we  at  head(iuarters  are  better  ciuali- 
fied  to  do  than  most  others,  the  test  appeared  to  have  only 
partially  served  its  purpose,  which  was  to  indicate  amateur 
radio  civil  defense  potential.  We  tliink  the  potential  is  con- 
siderably greater  than  shown  by  test  results  received  here. 


Under  the  heading  of  "Wouldn't  It  Be  Nice  If  .  .  ." 
most  of  our  emergency  net  organizers  and  net  controls 
would  list  "...  we  had  clear  channels  for  our  emergency 
nets."  We  agree  —  it  xoould  be  nice,  and  if  we  are  going  to 
dream,  that's  a  good  enough  thing  to  dream  about.  But 
alas,  comes  the  awakening  and  we  have  to  face  the  fact 
that  we  do  not  have  clear  channels,  and  only  in  the  direst 
emergency  can  we  expect  to  have  anything  approaching 
them.  It  is  common  practice  among  many  nets  to  request 
casual  stations  to  QSY  when  they  cause  QRM  to  a  net 
drill,  simulated  emergency  test  or  any  other  AREC  or 
RACES  activity.  Some  of  them  move  gladly  (often  only 
to  run  into  another  net),  some  reluctantly  with  mutterings 
or  sarcasm,  and  a  few  stand  on  their  rights  and  downright 
refuse  to  budge.  All  who  are  asked  to  move,  even  those 
few  who  might  agree  that  what  you  are  doing  is  more 
important  than  what  they  are  doing,  experience  at  least 
a  slight  twinge  of  irritation. 

The  averages  amateur  will,  when  he  realizes  that  he 
is  interfering  in  a  net  drill,  move  off  of  his  own  accord,  or 
QRT  until  the  drill  is  over,  without  being  asked.  Those 
who  do  not  do  so  are  usually  the  tj-pe  who  would  not  do  so

even  after  being  asked,  and  the  only  result  of  asking  them 
will  be  creation  of  hard  feelings,  or  exchange  of  harsh  words 
over  the  air.  So  what  have  you  gained? 

The  solution?  There  is  none,  really.  Our  amateur  bands 
are  crowded,  and  we  should  be  glad  they  are,  because  if 
they  were  not  we  probably  wouldn't  keep  them  intact 
very  long.  Such  being  the  case,  we  have  to  make  the  best 
of  a  situation  in  which  not  all  amateurs  are  consciously 
dedicated  to  public  service,  and  grin  and  bear  it  —  and 
think  of  how  nuich  practice  we  are  getting  trying  to  copy 
traffic  or  emergency  dispatches  under  adverse  conditions. 

On  February  25th,  ice  and  water  seepage  broke  an 
underground  cable  in  La  Crosse,  Wise.,  severing  com- 
munications witli  CAA's  French  fsland  facility.  W90GT, 
a  communicator  working  for  CAA,  went  into  action  from 
liis  mobile,  contacting  \V9GPU  in  La  Crosse.  WOfiPU 
contacted  WOOOL  in  Afadison,  who  served  as  a  delivery 
point  for  hourly  weather  se(iuence  reports  to  USWB  officials 
in  Madison  until  the  cable  was  repaired.  North  Central 
Airlines  also  benefited  from  this  operation.  As  a  result  of 
this  service,  W9AZN,  representing  C.\.\,  presented  the 
two  amateurs  with  certificates  of  appreciation. 

On  May  6th,  1819  CST,  tornadic  winds,  rain  and  hail 
hit  Temple,  Texas,  wreaking  much  destruction  and  knock- 
ing out  power.  Members  of  the  Temple  Amateur  Radio 
Club  were  alerted  and  assembled  at  the  Police  Station  on 
a  standby  basis.  Shortly  thereafter,  in  answer  to  a  call, 
the  amate\irs  furnished  a  power  generator  for  flood  lamps 
at  the  scene  of  the  major  damage.  This  power  unit  was 
taken  out  of  service  at  2200  when  the  National  Guard 
arrived  with  other  power  units.  Commimications  were 
furnished  from  the  scene  of  the  disaster  by  \V.3PNP/m 
and  W5VLF/m  through  fixed  station  WoCHF.  Stations 
participating  were  Was  VLF  SBS  CHF  JIB  WDW  WMX

On  May  14th,  wliile  driving  about  .30  miles  from  Houston, 
WoGLS  suddenly  became  ill.  He  contacted  W5GVW/m 
on  75-meter  mobile,  and  had  them  call  his  doctor,  who 
advised  W5GLS  to  get  to  any  hospital  as  soon  as  possible. 
When  GLS  indicated  the  hospital  he  was  headed  for,  the 
doctor  called  this  hospital  and  made  all  arrangements. 
W5GVW/m  also  made  arrangements  for  a  police  escort. 
Tiie  doctor  stated  that  if  GLS  had  not  gotten  to  the  hospi- 
tal, he  would  have  died.  W5GVW,  assisted  by  WN5GWP, 
handled  this  emergency  traffic  like  an  old  timer.  —  WoFEK 


A  plane  crash  in  Northboro,  jMass.,  alerted  the  Worcester 
AREC  group  on  May  26th.  EC  WlSPF  started  the  ball 
rolling  by  firing  up  on  ten  meters  as  soon  as  he  iieard  about 
the  crash  and  calling  WIL'QW,  who  was  talking  witli 
WlYPIv  in  Holden.  In  less  than  two  hours,  nine  other 
stations  had  reported  in,  completely  \\ithout  warning  or 
notification  of  any  kind,  sho\\-ing  how  frequently  members 
of  the  Worcester  AREC-RACES  group  guard  their  emer- 
gency net  frequency.  WlZMM/m  went  to  the  fire  depart- 


ment at  Northboro  and  was  told  an  ambulance  had  already 
been  sent  to  the  scene  of  the  crash.  WIMIA  was  asked 
by  the  Marlboro  Airport  to  locate  the  plane  and  get 
the  name  of  the  party  or  parties  involved  in  the  crash. 
WlZMM/m  and  Wl.iwM/m  proceeded  to  the  scene  of 
the  crash,  Vnit  police  withheld  the  name  of  the  crash  victim, 
wlio  was  killed.  The  i)lane  number  was  reported,  howe\er, 
to  the  Marlboro  authorities  by  amateur  radio.  WILQW 
handled  the  net  activity  and  everybody  cooperated  100 
per  cent.  Others  who  participated  include  Wis  EBU  RCJ 
MEG  MT  BIA  and  PMZ.  —  WlSPF,  EC  Worcester,  Mass. 


The  Purgatoire  River  in  Colorado  went  on  a  rampage 
on  May  26th  and  gave  the  little  town  of  Trinidad,  Colo., 
a  pretty  hard  time,  .\mateurs  from  throughout  the  area 
figured  prominently  in  the  commimications  work.  W0NVU 
took  the  brunt  of  the  load  in  Trinidad  itself,  with  amateurs 
from  all  over  the  state  and  adjoining  states  helping  out 
with  the  traffic,  most  of  it  welfare.  Bob  worked  for  40  hours 
without  a  break.  He  was  assisted  by  the  Hi  Noon  Net  and 
other  stations  from  the  general  area  in  handhng  over  300 
emergency  messages  into  and  out  of  the  flooded  district. 
K0WBB,  with  ^L<lc  operating  from  Fort  Carson,  was  also 
very  active  in  this  work.  Mac  later  took  a  mobile  unit  to 
Trinidad,  leaving  K0WBB  operation  to  two  other  operators, 
Milt  Moore  and  Dave  Morset.  Others  known  to  have  been 
assisting  were  W0s  SUP  PCJX  KQD  ICR  PGN  K0ANZ 
W7SPI/0  Quentin  Fuller,  Tommy  Clark. 

A  missing  person  search  at  Amos,  Quebec,  required  the 
assistance  of  amateurs  in  that  area.  The  Molson  Emergency 
Unit  (a  de  luxe  emergency  trailer  unit  sponsored  by  Mol- 
son's  Brewery)  traveled  from  Montreal  to  Amos  to  par- 
ticipate in  the  search,  but  had  to  leave  without  its  regular 
operator,  VE2MW.  Siscoe  EC  VE2FL  contacted  the 
driver  as  the  unit  was  passing  through  town  and  offered 
assistance.  Then  he  called  Assistant  EC  VE2ADD  at  Amos, 
who  agreed  to  alert  local  amateurs  to  assist  in  the  search. 
Thus,  when  the  unit  arrived  at  .A.mos  it  was  proxided  with 
a  radio  operator  in  the  person  of  VE2AHV,  who  went 
with  it  to  search  headquarters,  20  miles  northeast. 

The  station  in  the  unit  went  on  the  air  at  1430  EST 
and  was  operated  almost  continuously  by  VE2AHV  and 
VE2ADD  (who  arrived  later)  until  2330.  VE2ADA  was 
also  on  hand  to  help  operate  hand-carried  units  with  the 
mobile  unit.  The  search  continued  on  June  8th  and  June 
9th,  with  the  following  amateurs  taking  part  in  the  action: 
VE-2S  AOF  AVH  ADI  AEV  OB  HL  AHU  FL  and  VE3TX. 
The  search  was  abandoned  on  June  10th  at  2300.

Fourteen  SECs  reported  April  acti\-ities  on  behalf  of 
.5228  AREC  members.  This  includes  a  report  from  the 
North  Texas  SEC  which  was  in  written  nonstatistical 
form.  It  also  includes  reports  from  old  stand-bys  in  the 
following  sections:  Minn.,  Wash.,  Tenn.,  Western  N.  Y., 
N.  Y.  C.-L.  I.,  Georgia,  E.  Fla.,  Ala.,  San  Joaquin  Valley, 
Wise,  S.  Dak.,  Los  Angeles  and  Oregon.  Twenty-three 
SECs  have  now  submitted  reports  in  1955.  The  April 
reporting  record  is  equal  to  that  of  a  year  ago  in  number 
of  reports,  far  exceeding  it  in  AREC  members  represented.

RACES  News 

Operation  Alert,  19.55,  has  come  and  gone.  RACES  was 
active  —  more  so,   we   dare  say,    than   most   branches   of 
civil  defense  in  most  parts  of  the  nation, 
generally  speaking.   Reports  from   par- 
ticipants   are    beginning    to    reach    us. 
There  u>iU  be  a.   QST  write-up   on   tlie 
amateurs'   particiijation  in   this  nation- 
wide   exercise,    in    Sejjtember    QST    if 
we    can    make   it.    Its    location    in    the 
magazine  will  of  course  depend  on  the 
material   available.   So  send   us   ijhotos 
if  you  want  to  make  it  "up  front"  material;  otlierwise  it 
may  be  relegated  to  six  point. 

Recent  conversations  with  people  at  Battle  Creek  (FCDA 
National  Hq.)  bring  out  niunerous  facts  and  opinions 
concerning  the  test,  mostly  a  result  of  monitoring.  One  of 
the  most  glaring  deficiencies  noted  from  that  level  was 
the  improper  use  of  frequencies  and  technique,  according 
to  a  pre-copy  telephone  conversation.  The  feeling  is  that 
not  enough  advantage  is  being  taken  of  the  use  of  c.w.  for 
medium-  and  long-haul  traffic  in  most  areas.  Instead, 
attempts  (often  futile,  almost  always  frustrating)  are  being 
made  to  handle  all  this  traffic  on  7.5-meter  'jihone. 

The  above  comments  are  not  oiu's;  they  come  unsolicited 
from  FCDA  Headquarters,  where  monitoring  indicated 
too  mvich  use  of  75  'phone,  not  enough  use  of  80  c.w.  for 
RACES  operations  during  the  drill.  Also,  no  action  was 
heard  on  the  DCS  freq\iencies  of  1750-1800  kc,  and  only 
one  network  was  observed  operating  in  the  160-meter 
RACES  segments.  One  station  was  heard  using  c.w.  on 
.3993  kc,  trying  to  cut  tlirough  the  QRM. 

All  things  are  relative,  however.  We  are  better  off  thinking 
our  performance,  generally  speaking,  was  below  standard 
(that  is,  below  the  standard  we  wovdd  like)  than  resting  on 
our  laurels,  such  as  they  are.  Actually,  the  nation-wide 
RACES  establishment  compares  most  favorably  with  any 
other  branch  of  civil  defense  in  its  participation  in  this  test. 
In  the  few  local  control  centers  we  visited,  RACES  facilities 
operated  longer  and  harder  than  any  other  c.d.  facility. 
Publicity  was  favorable.  We  made  a  good  showing;  but  it 
could  be  a  lot  better.  Next  year  it  shall  be. 


South  Dakota  amateurs  are  getting  after  their  state 
officials  to  start  something  along  RACES  lines.  At  a  meeting 
in  Mitchell  on  April  17th,  W0GCP  called  the  meeting  to 
order  and  speakers  included  W0GCP  (the  SEC),  W0RRN 
(the  SCM)  and  several  other  ARRL  and  state  officials. 
The  governor  has  been  contacted  and  has  expressed  himself 
in  favor  of  organizing  the  amateurs  for  c.d.  The  group  at 
Mitchell  recommended  the  appointment  of  Myron  .Jones, 
W0OXC,  as  state  radio  officer.  The  meeting  continued  to 
discuss  detailed  plans  for  statewide  organization  under 
the  AREC  and  R.-VCIOS.  Keep  your  eye  on  .South  Dakota. 

In  New  York  State,  W2BC;0  reports  that  the  RACES 
organization  is  assisting  the  Radiac  (radiological  monitor- 
ing) branch  of  civil  defense  by  transmitting  c.d.  fallout 
weather  reports  twice  a  day  exceiit  week-ends  and  holidays. 
They  are  received  from  the  Weather  Bureau  in  New  York 
City  by  radioteletype  and  put  on  tlie  air  at  1000  and  1700. 
Radiological  chiefs  throughout  tlie  state  have  the  radiac 


people  receive  these  reports,  break  tliem  down  and  plot  the 
winds  aloft.  It's  good  training  in  communication,  meteor- 
ology and  coordination  combined. 

Another  state  to  keep  your  eye  on  is  Kentucky.  SEC 
W4CDA  reports  having  attended  a  meeting  on  April  8th 
in  which  a  great  many  state  c.d.  officials  were  included, 
including  W4BAZ  (Communications  Director  of  3rd  Mobile 
Support  Ciroup)  and  W4MGT  (Communications  Director 
of  state  OCD).  At  this  meeting,  the  discussion  centered 
around  establishing  c.d.  communications  to  the  amateurs 
in  a  R.^CES  network.  It  was  decided  that  the  state  OCD 
will  endeavor  to  get  funds  for  equipment  to  establish  such  a 
network. 

TRAFFIC  TOPICS 

Every  traffic  net  is  an  emergency  net,  and  every  emer- 
gency net  is  a  traffic  net.  This  is,  or  should  be,  axiomatic  in 
our  public  service  establishment  among  amateurs.  It  is 
something  which  we  have  urged  many  times,  and  it  bears 
repeating. 

Each  of  us  has  at  one  time  seen  an  emergency  net  in 
which  members  seem  to  have  no  conception  of  how  to  handle 
traffic;  and  most  of  us  have  also  seen  traffic  nets  which  not 
only  have  no  plans  for  but  disdain  operating  in  an  emer- 
gency. Each  group  has  something  to  learn  from  the  other. 
Traffic  handling  and  emergency  preparedness  are  not  dis- 
sociated subjects.  For  a  traffic  net  which  cannot  effectively 
operate  under  emergency  conditions  is  not  much  of  a  traffic 
net,  and  an  emergency  set-uji  which  cannot  effectively 
handle  traffic  will  be  an  awful  Hop  in  an  emergency. 

Enough  said?  No,  not  quite.  This  is  a  traffic  column,  and 
we  are  here  concerned  principally  with  traffic  nets.  It  seems 
to  us  tliat  there  are  an  awful  lot  of  them  in  operation  these 
days  which  have  no  plans  to  oi)crate  in  an  emergency.  How 
about  in  your  section?  Do  plans  exist  to  activate  your  net, 
on  its  regular  ojjerating  fre(|uency,  to  handle  both  official 
and  individual  welfare  messages  at  a  moment's  notice?  If 
no,  why  not  get  together  with  your  SEC  to  put  such  plans 
into  effect? 

As  for  the  National  Traffic  System,  plans  for  activating 
these  nets  for  emergencies  have  existed  right  along.  They 
were  first  iiromulgated  in  an  Emergency  and  Traffic  Bulletin 
dated  "Spring,  1950."  We  think  they  will  now  bear  re- 
peating. 

When  an  emergency  situation  arises,  regardless  of  the 
time  of  day  or  night,  the  NTS  net  or  nets  in  the  affected 
area  should  be  activated  and  ready  to  handle  any  and  all 
emergency  traffic,  while  NTS  nets  in  surrounding  areas 
should  be  activated  to  take  care  of  outside  communications 
if  and  when  called  upon.  Deijending  upon  the  urgency  in- 
volved and  the  volume  of  emergency  traffic,  official  or 
otherwise,  the  net  manager  concerned  has  the  duty  of  de- 
termining wliether  his  net  in  any  particular  situation  shall 
handle  official  emergency  traffic  only,  all  emergency  traffic, 
or  all  traffic  as  usual.  His  decision  should  be  complied  with 
by  all  traffic  handlers  concerned. 

The  extent  of  NTS  activation  in  emergencies  depends 
entirely  on  the  extent  of  the  emergency.  If  a  local  flood, 
the  section  traffic  net  will  probably  be  sufficient.  If  covering 
an  area  of  several  states,  probably  the  regional  net  should 
he  activated  in  addition  to  section  nets,  with  "shuttle" 
liaison  between  them,  and  possilile  activation  of  the  area 
circuit  to  provide  outside  contact.  If  the  emergency  is  area- 
wide,  all  NTS  nets  within  that  area  should  be  on  the  job, 
with  possible  activation  of  an  adjacent  area  net  to  provide 
oiitside  contact. 

The  above  is  policy  now  with  the  National  Traffic  System. 
We  think  it  should  be  an  over-all  policy  of  traffic  nets  to  be 
worked  into  their  section-wide  emergency  organization.  In 
some  cases  this  has  already  been  done.  In  those  where  it  has 
not,  don't  you  traffic  men  wait  for  your  SEC  to  act.  Offer 
your  services  and  those  of  whatever  net  you  represent.  As 
a  traffic  man,  you  can  do  a  world  of  good  in  any  emergency. 

Two  miscellaneous  traffic  net  reports:  (1)  Early  Bird  Net 
traffic  count  for  May  was  613;  (2)  The  First  Call  Area  sec- 
tion of  TCPN  registered  749  messages,  with  12  stations 
participating,  during  May.  The  Second  Call  Area  section 
reported  571  messages  with  9  stations. 

From  an  anonymous  contributor:  "Heard  the  following 
on  7.5  'phone:  'Say  OM,  I  am  short  five  or  six  messages  in 
my  tally  for  making  BPL  this  uujutli.  Can  you  think  up  any 


68 


QST  for 


old  thing  and  send  it  to  me  and  I  will  make  a  message  out 
of  it  so  I  can  add  to  the  score.' 

"What  in  the  world  has  happened?  Have  the  young 
squirts  turned  BPL  into  a  SS  contest?" 

National  Traffic  System.  Anent  the  prospect  of  reactivat- 
ing the  Mountain  Area  Net,  W0KQD  has  compiled  some 
statistics  to  show  that  it  "ain't  easy."  The  Mountain  Area 
(i.e.,  generally  speaking  the  area  encompassed  by  the  MST 
zone)  has  a  population  of  less  than  one  third  that  of  the 
Pacific  Area,  about  a  tenth  of  the  Central  Area  and  a 
fifteenth  of  the  Eastern  .\rea.  Amateur  population  is  roughly 
comparable.  There  would  also  be  the  necessity  for  twelve 
additional  TCC  schedules  per  week.  To  reactivate  a  Moun- 
tain Area  Net,  W0KQD  concludes,  would  require  a  great 
many  more  ardent  NTSers  than  now  appear  to  be  extant, 
at  least  equivalent  to  those  in  the  Eastern  Area  with  its 
much  larger  population. 

Do  they  exist?  If  not,  can  they  be  created?  Colorado 
alone  is  contributing  more  personnel  to  TCC  than  any 
other  single  state.  If  the  entire  Pacific  Area  produced  TCC 
operators  at  the  same  rate  as  Colorado,  that  Area  would 
have  7.5  TCC  operators.  Central  Area  would  have  177 
operators,  and  Eastern  Area  would  have  323  operators.  But 
an  area  organization  cannot  rest  on  the  shoulders  of  one 
section.  How  about  some  of  the  other  Mountain  Area  states? 
If  you  want  a  separate  Mountain  Area  organization,  you'll 
have  to  produce  the  operators.  It  was  for  lack  of  operators 
that  MAN  had  to  be  abandoned  in  the  first  place.

Several  section  net  managers  have  asked  why  their  nets 
cannot  get  more  than  summary  mention  in  this  column. 
The  reason  is  that  there  simply  isn't  room,  fellows.  Your 
SCM's  activities  column  is  the  place  for  mention  of  any 
details  of  section  net  operation.  The  mention  below  of  re- 
gional and  area  nets  is  included  here  because  these  nets  are 
not  within  section  boundaries;  if  they  were,  undoubtedly 
they  also  would  receive  no  space  here.  But  section  nets  are 
a  very  vital  part  of  NTS,  make  no  mistake  about  it.  We 
would  like  to  have  data  each  month  on  your  schedule, 
number  of  sessions,  traffic  handled  and  list  of  NCSs. 

Net  notes:  IRN  conducted  a  special  session  on  Saturday, 
May  21st,  to  assist  the  Cranston,  R.  I.,  YMCA  drive,  at 
which  amateur  radio  was  a  feature.  The  net  was  active  from 
1300  until  after  2000  that  day,  handled  86  messages.  A  3RN 
certificate  has  been  issued  to  W3YYC.  Heavy  QRN  is 
hampering  operation  of  4RN,  but  new  manager  W4BVE 
is  showing  progress.  RN5  is  handling  more  traffic  than  ever 
before  in  its  history.  Much  of  this  is  due  to  the  efforts  of 
old-time-traffic-man  W5IGW,  who  is  QNI  almost  every 
session  and  on  May  21st  NCSd  the  net  for  six  hours, 
clearing  204  messages.  RN6  expects  to  have  a  KH6  repre- 
sentative soon.  Many  sessions  of  8RN  were  not  reported 
in  May.  TRN  is  now  operating  two  sessions  nightly,  at 


1845  and  1945  EST  Monday  through  Friday,  the  early 
session  on  7070  kc.  and  the  late  one  on  3535  kc.  TRN 
certificates  have  been  issued  to  VEs  lOM  IHJ  2DR  2CP 
3BUR  3AVS  3TM  3A.JR  and  3AUU. 

TCC  Area  Directors  are  having  a  tough  time  keeping 
their  rosters  full  during  the  summer.  W8UPB  reports  for 
Eastern  Area  that  eight  TCC  stations  made  25  reports  in 
May,  with  WIEMG  passing  the  most  traffic.  W6HC  reports 
for  Pacific  Area  that  nine  TCC  stations  reported,  with 
W0EKQ  handling  the  greatest  amount  of  traffic.  Harry  is 
also  desirous  of  relinquishing  his  TCC  job,  now  that  he  has 
taken  over  as  ARRL  Director.  Any  takers?

DXCC  NOTES 

In  accordance  with  the  DXCC  rules,  "  Confirmations 
from  additional  countries  may  be  submitted  for  credit  each 
time  ten  additional  confirmations  are  available."  The  large 
number  of  cards  currently  being  submitted  in  batches 
smaller  tlian  tlie  required  ten  is  resulting  in  a  tremendous 
amount  of  extra  work  and  conseriuent  delay  in  handling. 
These  can  be  reduced  if  DXCC  members  will  adhere  to  this 
rule.  Endorsements  (and  subsequent  QST  DXCC  box  men- 


tion) are  issued  only  when  sufficient  cards  are  submitted  to 
increase  a  total  from  one  bracket  (110,  120,  130,  etc.)  to 
another.  There  is,  thsrefore,  no  point  to  sending  confirma- 
tions that  increase  j,  total  from  135  to  137,  for  example.  In 
such  a  case,  a  member  may,  of  course,  submit  only  five 
cards,  to  bring  his  total  to  140. 

In  order  tliat  the  Honor  Roll  listings  and  W/VE/VO 
Call  Area  and  Continental  Leader  listings  may  be  main- 
tained from  month  to  month,  three  exceptions  to  the  rule  are 
allowed:  (1)  If  you  already  have  credit  for  235  or  more 
countries  (c.w. /'phone),  or  can  bring  your  total  above  235  by 
submitting  fewer  than  the  ten  cards  required  by  the  rules, 
we  invite  you  to  do  so.  (2)  If  you  already  have  credit  for  200 
or  more  countries  on  'phone,  or  can  bring  your  total  above 
the  200  mark  by  submitting  fewer  than  ten  cards,  you  are 
similarly  invited  to  send  in  the  additional  confirmations. 
(3)  If  a  W/VE/VO  can  bring  his  total  above,  or  tie,  that  of 
the  leader  in  his  call  area,  or  those  outside  of  W/VE/VO  can 
tie,  or  bring  tlieir  totals  above  the  leader  on  their  continent 
as  shown  in  the  DXCC  box.

Tee-Notch  Filters 

cyVlAW  times  in  a  ham  shack  or 
in  the  laboratory,  occasion  arises 
for  the  need  of  a  simple  circuit 
which  can  be  used  to  "null  out"  or 
"notch  out"  a  very  narrow  band 
of  frequencies.  For  example,  at 
audio  frequencies  if  an  amplifier  were  fed  with  a  400  C.P.S. 
input  signal,  if  at  the  output  we  could  trap  out  the  400  C.P.S., 
the  remaining  audio  power  present  would  be  the  harmonics 
of  the  original  400  C.P.S.  and  thus  would  be  had  a  simple 
and  effective  distortion  factor  meter. 

(2^1  BRIDGED  tcc  uctwork  that  performs  this  function  has 
been  available  for  a  number  of  years  and  has  been  used  at 
audio  and  also  r.f.  frequency  to  at  least  as  high  as  50  Mc. 

vVe  at  Hallicrafters  prefer  to  call  it  a  tee-notch  filter  and 
we  use  it  for  all  sorts  of  trap  circuits  around  the  plant  and  in 
the  laboratory  and  also  find  it  \'ery  effective  to  trap  the 
fundamental  output  of  a  transmitter  to  measure  the  remaining 
total  harmonics. 

C/ne  fine  feature  of  this  network  is  that  its  insertion  loss  is 
reasonable,  about  3  db  at  50  kc,  and  also,  its  suppression  of 
the  desired  frequency  may  be  as  much  as  60  db.  It's  simple, 
stable,  and  normally  does  not  require  any  tubes  if  the  circuit 
to  which  it  is  added  has  3  db.  of  reser\-e  gain. 

VVE  feel  that  this  tee-notch  filter  has  many  advantages  in 
receivers  and  for  those  of  you  that  want  more  detail  a  data 
sheet  has  been  prepared.  A  postal  or  QSL  card  addressed  to 
me  will  insure  that  you  will  receive  one  of  these  sheets.

THE  AU  NiW  COMMUNICATIONS  RECEIVER 


THE  TECHNICAL  MATERIEL  CORPORATION,  and  TMC  CANADA,  LIMITED,  have  for  many  years 
been  engaged  in  the  manufacture  and  sale  of  high  quality  precision  communications  equipment 
such  as,  high  stability  direct  reading  oscillators,  radio  teletype  frequency  shifters  and  con- 
verters, broadband  transformers,  tone  telegraph  systems  and  diversity  and  fixed  tuned 
receivers.  Millions  of  dollars  worth  of  this  equipment  is  in  use  in  twenty  or  more  countries 
throughout  the  world.  Three  of  our  receivers,  the  DDR,  the  DRP  and  the  FFR  are  now  in 
regular  use  by  the  United  States  and  Canadian  Air  Forces  and  Navies,  so  we  felt  we  could 
produce  a  really  good  communications  receiver  containing  many  of  the  high  priced  requirements 
of    the    military   and    yet    keep    medium    price    range    for    the    amateur. 

In  our  work,  both  consulting  and  manufacturing,  we  hove  tested  practically  every  receiver 
in  the  field  and  have  included  every  basic  feature  inherent  in  a  good  unit  but  have  added 
some  new  ones  of  our  own.  Compare  our  features  to  any  receiver  in  any  price  range.  Bulletin

K2EQD  is  back  from  a  Naval  Reserve  cruise  to  Florida. 
Network  activities  in  NJN  are  slowing  down  a  bit  because 
of  summer  activities.  JKH  is  off  the  air  until  the  fall  season 
rolls  around.  K2HXP  has  built  a  new  rig  and  would  like  to 
get  in  touch  with  W2HXP.  If  W2HXP  could  arrange  a  sked 
it  would  be  appreciated.  KN2KHZ  is  burning  up  the  air 
these  days.  So  far  he  has  worked  31  states.  K2CHI  is  active 
in  RACES  nets.  CVW  is  QRT  for  a  few  weeks  because  of  a 
moving  job  which  has  to  be  done.  K2GAS  received  a  G.  E. 
certificate  for  participation  in  emergency  traffic  nets  during

Comm.  Officer  for  Interlaken.  At  this  writing  all  hands  are 
hard  at  work  preparing  for  "Operation  Alert  1955."  From 
all  indications  RACES  activities  in  the  section  will  reach  a 
new  high  during  the  period  of  the  test.  State  Civil  Defense 
authorities  are  counting  very  heavily  on  amateur  radio  to 
carry  the  bulk  of  traffic  which  will  flow  from  the  bombed-out 
areas  where  land  lines  have  been  destroyed.  New  Jersey 
State  RACES  networks  have  accepted  the  challenge  and  are 
ready  to  take  over.  Our  thanks  go  to  the  County  ROs  who 
have  made  the  program  possible.  A  late  news  flash  has 
brought  the  good  news  that  the  new  amateur  license  plate 
bill  has  just  passed  both  branches  of  the  State  Legislature 
and  is  before  the  Governor  for  signature.  NUI  has  done  a 
fine  job  in  following  this  project  to  the  bitter  end.  There 
have  been  many  adverses  along  the  road  but  he  has  stayed 
with  it.  He  has  appointed  a  new  committee  to  meet  with  the 
Director  of  Motor  Vehicles  to  pave  the  way  for  the  Gov- 
ernor's signature  to  the  bill.  The  new  committee  is  com- 
posed of  ZI,  HX,  and  your  SCM.  We  hope  by  the  time 
you  read  this  column  the  bill  will  have  been  signed  into  law. 
The  State  Director  of  Civil  Defense  and  Disaster  Control 
has  promised  to  lend  a  hand  in  putting  the  importance  of 
this  bill  before  the  Governor.  K2ICE  has  a  new  horizontal

How  to  select  a  tube  for  single  sideband 


lo  realize  the  advantages  of  Single  Sideband 
operation,  there  are  two  important  points  to  keep 
in  mind  when  selecting  a  final  amplifier  tube. 
First,  since  there  is  no  continuously  running  car- 
rier, high  peak  powers  may  be  reached  when  a 
signal  is  put  on  the  air.  And  second,  because  it  is 
easier  to  produce  an  SSB  signal  at  a  low  power 
level,  it  takes  more  than  an  ordinary  tube  to  build 
this  valuable  low  power  signal  from  the  modulator 
to  high  power  in  a  single  amplifier  stage.  Eimac 
tubes  offer  these  extras.  Their  reserve  supply  of 
filament  emission,  lack  of  internal  insulators  and 
widely  recognized  ability  to  handle  high  peak  pow- 
er has  been  provetl  over  the  years.  And  high  power 
gain  is  inherent  in  all  Eimac  multi-grid  tubes.  When 
planning  or  building  an  SSB  rig,  remember  these 
two  important  points  and  consider  the  Big  Six  of 
Amateur  Radio-Eimac  4-65A,  4-125A,  4-250A, 
4-400A  and  4X250B  radial-beam  power  tetrodes 
and  the  4E27A  radial-beam  power  pentode.

One  of  the  outstanding  features  of  the  new  Bandmaster  line 
is  its  adaptability  to  limited  space.  Each  unit  being  only

MALLORY 

Wire  Wound  Controls 


Tlie  year  after  year  continued  preference  for  Mallory  wire-wound  controls,  in  amateur  handljook  and 
magazine  "how  to  build  it"  articles,  is  a  wonderful  testimonial  to  the  technical  skill  and  ability  of  Mallory 
engineering.  Continued  amateur  patronage,  plus  enthusiastic  acceptance  by  professional  users,  has  made 
the  production  of  small  wire-wound  controls  at  Mallory  a  highly  controlled  and  uniform  process. 

'J  lie  manufacture  of  high  quality  wire-wound  controls  has  been  a  specialty  at  Mallory  almost  as  long  ^s 
such  controls  have  been  used  by  radiomen.  As  a  result,  practically  every  style  and  resistance  value  needed 
for  amateur  or  professional  application  will  be  found  listed  in  the  latest  Mallory  catalog.  There  is  a  style 
or  value  for  use  in  just  about  every  circuit  around  the  ham  shack  — "S"  meter  circuits,  bias  connlrol  »"  the 
cathode  of  RF,  IF,  and  modulator  tubes,  excitation  level  adjustment  in  crystal  oscillators,  T  and  L 
attenuators,  and  all  sorts  of  test  equipment  circuits,  to  mention  only  a  few. 

For  your  information  and  possible  help  the  next  time  you  require  a  wire-wound  control,  a  few  of  those 
available  in  the  latest  Mallory  catalog  are  listed  and  described  below. 


"C"  TYPE  2  WATT  WIRE-WOUND— This  control  is 
one  of  the  smallest  capable  of  dissipating  a  full  2 
watts.  It  measures  only  I'ie"  in  diameter,  and 
as  a  result  it  is  a  handy  control  for  many  bias,  "S" 
meter,  and  other  low  voltage  applications  where 
physical  size  is  a  factor.  It  features  a  grounded  rotor 
arm,  screw  driver  slotted  shaft,  and  a  full  266°  of 
electrical  rotation.  Resistance  values  from  6 
to  15,000  ohms  are  available. 

•R"  TYPE  2  WATT  WIRE-WOUND— The  "R"  control 
ias  many  amateur  applications.  Its  1500  volt  AC 
usulation  between  shaft  and  resistance  element,  and 
its  dust  proof  phenolic  case,  make  this  control  safe 
for  amateur  circuits  where  high  potentials  may  be 
encountered.  The  shaft  is  a  thumb  knurled  and 
screw  driver  slotted  stub  }yi"  in  diameter  to  which 
a  special  3"  extension  shaft  may  be  added  when 
desired.  The  "R"  control  is  made  in  resistances 
from  20  to  5000  ohms. 

In  addition,  the  Mallory  catalog  lists  a  variety  of  resistance  values  in  "T"  and  "L"  pads.  Center-tapped 
wire-wound  controls  and  units  with  tapered  windings  for  special  service  are  all  available  through  your 
nearest  Mallorv  Distributor.  See  him  today  for  Mallory  wire-wounds,  power  resistors,  carbon  controls 
and  those  other  Mallory  components  you  need  to  keep  your  equipment  in  good  operating  condition. 

In  the  meantime,  watch  for  the  announcement  of  new  Mallory  power  controls  from  25  to  500  watts. 


"M"  TYPE  4  WATT  WIRE-WOUND— This  control  is  the 
old  stand-by  used  by  more  amateurs  than  any  other 
made.  Wherever  variable  resistors  of  4  watts  or  less 
are  required,  the  "M"  control  should  be  the  logical 
choice.  With  resistance  values  of  0.5  to  70,000  ohms 
available  it  is  universally  acceptable  for  voltage 
division,  bias  control  and  test  instrument  circuits 
of  all  kinds. 

"E"  TYPE  7  WATT  WIRE-WOUND— The  7  watt  "E" 
control  fills  the  gap  between  the  low  power  "C", 
"R"',  and  "M"  controls,  and  the  higher  power  and 
more  expensive  units  of  25  watts.  This  control  is 
particularly  well  suited  for  use  in  screen  grid  and 
similar  circuits  where  voltage  division  or  adjustment 
is  desired.  Nine  resistances  are  available  from  5,000 
to  150,000  ohms.

The  Tri-Bander  is  a  compensated  type 
beam  with  four  elements  mounted  on  one 
15'  boom.  Two  elements  function  for  20 
meter  operation  and  the  other  two  for  15 
and  40  meter.  Because  the  latter  two 
bands  are  not  in  direct  harmonic  relation, 
the  beam  operates  at  somewhat  reduced 
efficiency  at  21  mcs.  but  gives  maximum 
performance  at  7  mcs.  and  14  mcs.  For- 
ward gain  on  these  bands  is  5  db.  and 
front-to-back  is  20  db.  SWR  is  1.1/1  at 
resonant  fretiuencies.  The  Tri-Bander 
is  complete  with  coils,  Auto-Lectronic 
Coupling  Yoke  and  all  necessary  hard- 
ware. Element  sections  are  pre-driiled

PACIFIC  DIVISION 

HAWAII  — SCM,  Samuel  H.  Lewbel,  KH6AED — 
Here  is  the  call  for  the  c.w.  gang.  Get  in  touch  with  your 
SCM  and  we'll  get  an  a)I  islands  c.w.  net  going.  Once  that 
is  rolling  we  will  arrange  for  scheduled  outlet  into  the 
transcontinental  system  for  deliveries  into  all  the  states. 
With  2-meter  activity  on  the  upswing  3  OES  appointments 
were  made:  KH6LD  Henry  Loo,  KHfiZD  Lawrence  Ching, 
and  OS  Tom  Hori.  LD,  mobile  on  Maui,  and  AED,  on 
Oahu,  made  2-meter  history  with  an  inter-island  contact. 
LD  is  running  less  than  2  watts  output  to  a  ground  plane 
on  the  roof  of  the  car.  Who  will  be  first  with  the  Hawaii- 
Oahu  contact?  Traffic:  (Mav)  KH6AJF  1895,  KA2GE

SANTA  CLARA  VALLEY  — SCM,  R.  Paul  Tibbs, 
W6WGO  — SEC:  NVO.  ZRJ  tuned  up  his  antenna  and 
is  getting  out  very  well  now,  thanks  to  George  Crammer's 
advice.  Doc  and  Ann  attended  the  Pacific  Division  Conven- 
tion at  Fresno.  K6CRN  is  working  on  MARS  under  the 
call  AA6CRN.  FON  received  his  license  renewal.  AIT 
finished  power  supply  for  a  new  final  using  a  pair  of  811s. 
YHM  returned  from  the  East  Coast  in  time  to  attend  the 
Convention  at  Fresno.  Don  left  for  KL7-Land  a  few  days 
after  returning  from  the  Convention  and  expects  to  be  in 
Alaska  for  about  three  months.  On  his  return  he  will  be 
back  on  the  traffic  nets  again.  KIN  just  finished  a  20-meter 
beam  using  inductive  coupling  rings.  Others  at  the  Conven- 
tion were  K6BBD,  W6HC,  WGO,  SHK,  APV,  YPM, 
FYM,  and  BPT.  ZRJ  now  is  Manager  of  RN6.  Doe  should 
have  the  net  operating  on  a  five-night  basis  again  by  the 
time  this  is  read.  NCN  needs  more  stations  in  Northern 
California  so  as  to  be  truly  NCN.  Stations  are  needed 
in  Sacramento  and  up  Redding  way.  Anyone  in  the  Mt. 
Shasta  Area  will  be  welcome.  There  also  is  need  for  a  station 
from  the  'phone  nets  to  work  on  RN6.  Traffic,  both  out- 
going and  incoming,  would  then  be  handled  much  faster. 
How  about  it,  gang?  Let's  make  this  section  again  a  leader 
in  traffic-handling  as  it  was  in  the  "good  old  days."  Traffic:

more  complete  club  papers  published  in  Northern  California. 
The  East  Bay  section  was  well  represented  at  the  Pacific 
Division  Convention  in  Fresno,  and  assisted  the  Fresno 
gang  in  many  ways  with  the  programs.  "Operation  Alert 
1955"  saw  amateurs  participating  fully.  Several  civil 
defense  leaders  have  gone  out  of  their  way  to  express  their 
full  appreciation.  ITH  has  been  traveling  through  a  fascinat- 
ing bunch  of  DX  countries.  The  Albany  Hi-Hi  CQers  club 
station,  KOEPE,  is  now  an  Official  Bulletin  Station.  The 
East  Bay  Radio  Club  heard  talks  by  Walt  Serniuk,  K6HQE, 
formerly  W2JAR,  and  Ray  Renaudo,  W6KEV,  in  May  and 
June.  The  V.H.F.  Party  in  June  was  highlighted  by  the 
activity  of  the  V.H.F.  Expeditionary  Society,  which  set

The  Sonoma  County  Radio  Club  had  ALF  as  guest  speaker 
for  its  May  meeting.  Frank  gave  an  interesting  demonstra- 
tion and  talk  on  the  tune-up  procedure  of  his  beams. 
LOU's  XYL,  Mae,  is  waiting  for  her  Technician  Class  ticket 
and  K6ITY's  XYL,  Joan,  is  awaiting  her  Novice  Class 
ticket.  K6BWQ  moved  from  the  Bay  Area  and  has  settled 
down  in  Eureka,  Calif.  He  is  one  of  the  telephone  company's 
salesmen.  Members  of  the  San  Francisco  Naval  Shipyard 
Club  held  their  annual  dinner  at  the  El  Portal  Cafe  May 
21st.  Your  SCM  had  to  miss  it  as  the  family  had  tickets 
for  the  Fresno  Convention.  HAMS  (the  Red  Cross  Club) 
had  Field  I^ay  business  and  a  6-meter  discussion  at  its  May 
meeting.  SON,  KFS,  URA,  TTB,  JAA,  CAN,  ULA,  OJT,

meters  is  URA,  who  sports  an  unhooked-up  829B  Tripler 
final  and  a  four-element  beam.  Neighbors  can't  blame  him 
for  TVI.  Many  of  the  local  29ers  Club  showed  up  at  Fresno 
but  the  10-meter  transmitter  hunt  signal  was  not  loud 
enough  to  be  heard  by  the  gang.  The  75-meter  transmitter

IDF  spoke  on  modern  trends  in  amateur  receivers  at  the 
U.  C.  Campus  on  May  24th.  Sorry  he  couldn't  stop  over 
longer  and  give  the  same  talk  to  some  of  the  local  radio 
clubs.  Sixty-nine  members  of  the  Mobileers  held  Sunday 
morning  breakfast  at  the  Belmont  Motel  at  Fresno.  Mr. 
Morrow,  of  the  Morrow  Co.,  gave  a  very  interesting  talk 
after  breakfast  and  told  the  boys  how  to  eliminate  some  of 
the  mobile  transmission  noises.  OPL's  XYL  won  the  main 
prize  at  the  YLs'  luncheon.  GGC  and  family  enjoyed  the 
Friday  night  dinner  with  the  Buzzards.  There  was  a  grand 
entertainment  after  dinner.  Dr.  Lester  Reukema,  of  U  C 
spoke  at  the  May  meeting  of  the  SFRC  on  "Industrial 
Ai)phcation  of  Atomic  Energy."  The  fellows  kept  him  busy 
answering  questions  after  a  very  interesting  talk.  Thanks 
to  ATO  for  obtaining  such  a  wonderful  speaker.  BIP  was 
a  very  busy  man  in  May  getting  rigs  and  manjjower  in  line

a  "writing  date"  with  some  of  the  boys  at  Litchfield  Pk. 
and  said  she  should  have  studied  code  because  Gordon's 
dad  was  sending  c.w.  FVK  came  back  via  'phone  so  she 
only  heard  a  one-sided  conversation.  PHS,  the  OM  of  QMO, 
promises  to  write  some  short  articles  about  radio  theory 
for  the  YL  Club.  OMO  is  checking  in  again  with  MTN 
but  stays  on  the  American  Legion  frequency  most  of  the 
time.  AHH  lost  his  way  and  couldn't  even  make  it  in  last

Pacific  Division  Convention  held  at  Fresno  was  a  huge 
success,  with  an  attendance  of  752.  The  gang  at  Fresno  is 
to  be  congratulated  for  a  swell  job.  Word  has  been  received 
that  W.JF  and  FEA  are  leaving  this  section  and  moving 
to  San  Francisco.  I  received  a  letter  from  TFD.  Eldon  is

SCM  I  wish  to  thank  all  the  gang  who  have  helped  me  and 
the  section  in  the  last  two  years.  The  San  .Joaquin  Valley 
section  has  made  great  strides  in  organization  and  activity, 
and  it  is  all  because  of  the  splendid  cooperation  of  the 
whole  gang.  K6EVM  announces  a  change  in  CVN  time  to 
8:00  P.M.  Chuck  is  working  hard  to  keep  the  section  net 
operating,  and  would  like  to  see  more  stations  take  a  part 
in  the  net.  The  section  nets  are  the  heart  of  tlie  National 
Traffic  System,  and  offer  a  wonderful  opportunity  for  those 
interested  in  c.w.  to  get  in  some  pleasant  operating  time. 
There  is  room  for  the  beginner  as  well  as  the  old-timer  on 
the  net,  and  the  section  net  is  ideal  for  the  slow  operator 
who  wants  to  increase  his  speed.  C'heck  in  on  3525  kc  at

For  Generating  Spot  Frequency  Signals  with  Guaranteed  Tolerance 
1000  KC  to  15,000  KC  fundamental  operation 

Since  the  operating  tolerance  of  a  cryslol  is  greatly  affected 
by  the  associated  operating  circuit,  the  use  of  the  FO-1  Oscillator 
in  conjunction  with  the  FX-1  Crystal  will  guarantee  close  tolerance 
operation.  Tolerances  as  close  as  .001   percent    con  be  obtained.

ratio  makes  signals  readable  that  are  ordinarily 
lost. 

100  K.C.  CRYSTAL  CALIBRATOR— Now,  for 

the  first  time,  MORROW  has  made  it  possible  for 
amateurs  to  read  exact  frequency  on  mobile 
receivers.  Assures  high  reset  accuracy. 

SSB  AND  CW  RECEPTION— Excellent  SSB  and 
CW  reception  is  assured  due  to  the  inherent 
stability  of  the  MBR-5.  No  warm-up  delay.  Fully 
temperature  and  voltage  compensated  oscillators. 
Will  hold  calibration  accuracy  with  changes  of 
0  to  150  degrees  F.  and  input  voltages  of  4  to  8

sive new  MORROW  Noise  Balance  Squelch  com- 
pletely eliminates  interstation  noise  but  will  readily 
open  on  weakest  signals.  The  improved  series 
gate  noise  limiter  is  extremely  effective  in  elimi- 
nating pulse  noises. 

ILLUMINATED  ^^S''  METER— Measures  in- 
coming signal  strength  and  used  as  a  field  strength 
meter  for  adjusting  mobile  transmitters  to  maxi- 
mum output.  A  must  for  mobile  amateurs.

BRITISH  COLUMBIA  — SCM,  Peter  M.  Mclntyre, 
YETJT  —  Sorry  to  report  the  passing  of  ZZ,  one  of  the 
original  hams  in  Vancouver  and  also  one  of  the  original 
signers  of  the  charter  of  the  British  Columbia  Amateur 
Radio  Association.  AAJ  reports  that  on  May  29th  amateurs 
in  the  Okanogan  took  part  in  a  civil  defense  exercise.  Those 
known  to  have  taken  part  were  AAJ,  EQ,  FS,  and  QC.  XY, 
at  Dawson  Creek,  is  bewailing  the  fact  that  band  conditions 
are  poor.  AUF,  Lois,  of  Spring  Island,  has  been  appointed 
EC  of  District  #2  of  Vancouver  Island.  Congrats  to  the 
Royal  City  Amateur  Radio  Assn.  on  becoming  an  ARRL 
affiliated  club.  US  suggests  that  3755  kc.  not  be  used  for 
long  ragchew  QSOs  but  be  kept  as  a  listening-out  frequency, 
which  I  believe  was  the  original  intention  of  3755  kc.  as  well 
as  being  the  net  frequency.  Make  your  initial  call  on  3755 
kc.  and  if  you  make  a  contact,  if  you  are  a  fixed  home  sta- 
tion, QSY  up  or  down,  which  will  leave  the  frequency  clear 
for  another  call  and  especially  for  the  mobiles.  But  don't 
forget  to  listen  once  in  awhile  on  3755  kc.  Another  bad  habit 
I  have  noticed  is  that  someone  gives  a  piece  of  traffic  for 
relay  during  the  net  and  all  and  sundry  who  have  heard  the 
traffic  pre-net  time  get  in  the  act  and  pass  that  traffic.  Don't 
do  it,  let  the  person  who  received  it  pass  it  as  he  was  asked 
to  do  by  the  originator.  There  will  be  no  column  next  month 
as  I  will  be  away  on  vacation  in  W9-Land,  I  hope.  Traffic:

p:icitor30  t()50  times  larger  than  the  tot.il  tuiiiiitf 
capacitance  to  counteract  it.  So  a  0.002-;uf.  ca- 
pacitor wa.s  placed  in  series  with  the  single-ended 
output  terminal  (stud  of  the  coa.x  connector)  and 
the  end  terminal  of  the  coil.  Then  the  two  binding 
posts  were  shorted  with  a  piece  of  straight,  round 
wire  and  the  coa.x  connector  was  plugged  into  a 
shorted  female  connector.  The  grid-dipper  then 
showed  resonance  at  12.3  Mc.  This  indicated 
that  the  capacitor  was  about  30  per  cent  larger 
than  it  should  have  been  so  it  was  replaced  with 
.0015  txi.  (1000  fini.  and  470  /x^f.  in  parallel 
shown  in  the  photograph).  A  grid-dip  check  with 
both  input  and  output  shorted  then  showed  reso- 
nance at  14. G  Mc,  again  amply  close. 

The  same  balun  turned  out  to  require  4  njjii. 
(plus  the  8  nfiL  distributed)  for  shunt  tuning  at 
28  Mc.  and  the  series  capacitor  was  420  M^f-  A 
10  per  cent  error  in  the  value  of  either  of  these 
capacitors  is  relatively  unimportant.  With  the 
values  indicated  for  14.3  Mc,  errors  caused  by 
the  balun  itself  were  so  small  as  to  be  unreadable 
when  used  with  a  bridge  such  as  the  one  described 
in  this  article  (well  below  1  per  cent  if  the  50,000- 
ohm  shunt-coil  losses  were  used  to  determine  a 
correction  factor). 

Omission  of  the  leakage-reactance  correction 
capacitor  made  cjuite  a  sizable  error  when  measur- 
ing loads  of  100  ohms  or  less  at  28  Mc.  Inclusion 
of  the  c;  pacitor  reduced  these  to  Ifess  than  2  per 
cent  for  any  value. 

As  mentioned  previously,  the  1000  /xni.  and 
470  MAtf-  forming  the  0.00147-Mf.  series  capacitor 
for  20-meter  operation  are  shown  in  the  illus- 
tration between  the  outer  terminal  of  the  winding 
and  the  center  stud  of  the  connector.  Either 
tuning  capacitor  (4  nfit  for  10  meters  or  39  fi/J. 
for  20  meters)  can  be  connected  externally  across 
the  binding  posts. 

\Yhen  using  the  balun  for  10  meters,  the  1000- 
/x/if.  portion  of  the  series  capacitor  is  opened. 

In  conjunction  with  the  bridge,  the  balun  de- 
scribed can  be  used  over  a  ±500-kc.  range  on  20 
meters  and  ±1  Mc.  on  10  meters,  without  re- 
tuning. 

Conclusion 

The  simple  antenna  bridge  described  here  can 
be  used  for  almost  any  tj^pe  of  r.f.  impedance 
measurement  that  the  amateur  is  called  upon  to 
make.  The  possibilities  in  this  regard  have  only 
been  touched  upon  in  this  article,  but  the  many 
applications  have  been  well  covered  in  amateur 
literature.  There  is  only  one  warning  —  do  not, 
under  any  circumstances,  leave  the  bridge  in  the 
circuit  while  the  transmitter  is  in  use.  The  bridge 
is  a  measuring  instrument,  not  a  device  for 
monitoring  the  performance  of  the  transmitter.

ticular  transistor  used.  The  transistor  in  this  unit 
was  found  to  have  a  current  gain  of  20,  or  26  db., 
so  that  full-scale  deflection  on  the  0-1-ma.  meter 
was  50  ixa.  To  calilirate  the  meter  for  microam- 
meter  measurements,  a  simple  calibration  circuit 
can  be  set  up  using  a  dry  cell  and  several  known 
resistances.  A  diagram  of  the  circuit  is  shown  in

Ohm's  Law  any  current  flow  through  the  circuit 
can  be  calculated  if  the  resistance  and  voltage  are 
known.  By  plugging  in  a  pair  of  headphones  and 
setting  the  function  switch  on  field  strength 
meter,  the  quality  of  a  'phone  signal  may  be 
observed.  The  transistor  is  acting  as  an  amplifier 
in  this  position,  so  the  gain  will  be  more  than 
enough  for  strong  headphone  volume.  This  fea- 
ture will  be  appreciated  when  monitoring  a  mo- 
bile 'phone  signal,  where  the  signal  strength  is 
low. 

The  basic  movement  of  the  meter  in  this  instru- 
ment may  be  used  by  switching  the  function 
switch  to  milliammeter.  Leads  are  connected  to 
the  pin  jacks  and  the  instrument  is  used  accord- 
ingly. External  shunts  may  be  used  with  the 
basic  0-1  ma.  movement  to  provide  an  extremely

Power  and  Meter  Facts 

{.Continued  from  page  25) 

will  do.)  Ne.xt,  I  adjust  the  coupling  of  the  feed- 
line  to  the  final.  The  coupling  is  set  for  maximum 
power  output  at  a  given  plate  current  at  reso- 
nance. If  the  coujjling  is  increased,  the  d.c.  plate 
current  goes  up,  but  the  output  either  remains 
constant  or  decreases.  This  point  of  maximum 
output  for  a  given  amount  of  input  comes  close 
to  the  magic  point  of  proper  adjustment  for  all 
linear  amplifiers.  The  old  method  of  loading  by 
reference  to  "dip  at  resonance"  is  not  recom- 
mended. Once  we  have  reached  the  suggested  ad- 
justment, we  have  had  it  as  far  as  coupling  goes. 
If  the  d.c.  current  is  less  than  800  ma.  (for  the 
amplifier  under  discussion),  we  simply  don't  have 
enough  linear  drive. 

Now,  regardless  of  the  power  I  believe  my  am- 
plifier should  handle,  I  make  a  crude  check  to 
determine  at  what  point  it  actually  flattens.  I 
vary  the  amount  of  carrier  insertion,  watching 
mainly  the  output  indication,  and  note  the  point 
at  which  increasing  the  carrier  no  longer  results 
in  a  rapid  increase  in  output.  I  now  observe  the 
plate  meter  reading,  hoping  in  this  case  that  it  is 
up  to  300  ma.  I  use  this  figure  to  multipl)^  by 
plate  voltage.  This  is  roughly  my  maximum- 
signal  linear  power  available.  Suppose  my  linear 
diive  available  limits  my  actual  plate  current  to 
250  ma.  My  maximum  signal  power  is  then  only 
375  watts  instead  of  the  possible  450. 

Next,  1  remove  the  carrier.  I  change  to  voice. 
This  is  the  point  where  experience  in  using  a 
'scope  counts.  I  know  that  my  voice,  using  the 
average  plate  meter,  will  deflect  the  meter  only 
about  half  as  far,  for  the  same  maximum  signal 
power,  as  the  carrier  did.  Thus,  since  my  steady 
signal  current  was  250  ma.,  I  wouldn't  expect 
much  over  125  ma.  on  normal  talking.  The  only 
way  to  achieve  more  meter  saving  under  this  set 
of  amplifier  conditions  and  not  splatter  would  be 
to  use  properly  designed  and  adjusted  compres- 
sion in  the  exciter's  audio. 

Reviewing  the  preceding  material,  you  can  de- 
termine that  my  "meter  peak,  on  voice"  or  legal 
power,  is  only  187  watts  (125  ma.  X  1500  volts). 
My  maximum  signal  or  peak  envelope  power  is 
375  watts  (250  ma.  X  1500  volts).  The  instan- 
taneous peak  power  is  about  750  watts.  As  the 
saying  goes,  "You  pajs  your  money  and  takes 
your  choice." 

Actually,  your  voice  might  be  able  to  swing  the 
meter  somewhat  more  than  mine  for  the  same 
amount  of  maximum  signal  power.  If  I  were  using 
a  Class  AB  amplifier  I  would  expect  the  meter  to 
swing  somewhat  higher  on  voice  in  relation  to  its 
reading  on  steady  signal. 

Don't  think  that  I  am  recommending  the  above 
procedure  as  a  replacement  for  legitimate  "two 
tone"  adjustment  with  a  'scope.  Anyone  who  has 
worked  with  linear  amplifiers  knows  that  insert- 
ing laige  amounts  of  stead}'  signal  (carrier  or 
single  tone  is  worse;  "two  tone"  less  punishing) 
has  the  rather  disconcerting  and  costly  tendency

OAUL  iO^^fOyU^    with  a  Gotham  Antenna  and  35 


watts. 


READ  THIS  AMAZING  LETTER:  How  an  inexpensive  FULL 
SIZE  Gotham  Rotary  Beam  made  it  possible  to  "work  the  world!" 


Gotham  HoM.v  Corp.  Florida,  13  May  1955 

107  East  126tli  St. 
New  York  35,  N.  Y. 
Gcntlcincn: 

I'd  like  to  express  my  enthusiasm  and  satisfaction 
re>;arding  your  20-metpr  rotary  beam  antenna.  I  pur- 
chased one  of  your  standard  two-element  units  in 
February  of  tills  year.  I'rior  to  this  time  I  harl  been 
using  a  eolliiicar  array  about  one  waveleiifith  above 
ground.  The  transmitter  feeding  this  antenna  had  a 
power  oiitp-.it  of  about  3.')  watts,  and  results  were  quite 
discouraviing. 

\\  hen  my  Gotham  arrived,  it  was  easily  assembleil 
in  a  couple  hours.  I'he  same  transmitter  was  used  to 
excite  the  Gotiiam  antenna,  using  the  same  power  as 
before,  iiesiilts  iia\e  been  (|uite  gratifying,  and  it  is 
interesting  to  note  that  in  the  three  months  since  using 
the  Gotham  antenna,  I  have  worked  87  foreign  coun- 
tries, all  continents,  and  30  /ones. 


I  am  able  to  keep  schedule  with  amateur  radio * 

in  the  Cape  \  erde  Islands  every  week.  It  was  impos- 
sible to  even  hear  this  station  be/ore  using  the  Gotham 
beam. 

I'.xtrcmely  liigh  winds  are  prevalent  in  this  part 
of  Florida.  The  Gotham  beam  has  withstood  blows 
in  excess  of  50  miles  an  hour  without  failure. 

The  elements  bend  almost  double  in  these  high 
winds,  but  readily  return  to  their  original  configura- 
tion when  the  wind  abates.  I  feel  that  this  is  an 
extremely  important  feature  of  the  Gotham  antenna. 
I  have  enthusiastically  recommended  Gotham 
to  all  the  hams  who  ask  what  type  I  am  using  (and 
most  of  them  do,  when  I  tell  them  the  amount  of 
power  I'm  using).  I  wish  you  every  success  with  your 
product,  and  feel  that  it  is  well  worth  the  modest  price. 

Yours  very  truly, 
(Names  and  *call  letters  upon  request.)

of  making  vacuum  tubes  melt.  Discretion  is  al- 
ways indictated  when  making  adjustments.  How- 
ever, if  cautiously  used,  the  procedure  is  guar- 
anteed to  do  one  thing  —  to  produce  a  signal 
vastly  more  neighljorly  than  one  generated  in  an 
all-out  attempt  to  wrap  the  jjoinler  around  the 
pin. 

While  1  have  been  writing,  I  have  had  a  vague 
feeling  of  someone  looking  over  my  shoulder  and 
wanting  to  say,  "I  always  knew  there  was  some 
reason  why  those  'sidebanders'  sound  so  terrible 
and  are  so  l)road.  Now  I  know.  They  are  all 
'meter  benders' !" 

Well,  old  man,  I  don't  want  to  start  an  argu- 
ment now,  but  remember  the  saying  about  peoi)le 
who  live  in  glass  houses.  Just  because  "sideband- 
ers" as  a  whole  are  "distortion  conscious"  it 
doesn't  necessarily  mean  that  they  invented  the 
stuff.  Sideband  enthusiasts  with  their  s.s.b.  re- 
ceiver, transmitters,  and  voice-control  operation, 
are  actually  achieving  a  worth-while  increase  in 
voice  communication  —  per  kiloc^xle  per  watt 
per  hour.  This  would  be  impossible  if  the  linear- 
amplifier  situation  was  really  "rotten." 

This  is  not  a  plea  for  more  than  a  small  percent- 
age of  the  present  operators  to  become  less  meter 
happy.  The  purpose  is  to  collect  a  few  facts  about 
the  use  of  d.c.  meters  in  voice  circuits  and  to  give 
some  pointers  concerning  power  calculations. 

Almost  everyone  who  first  uses  a  linear  ampli- 
fier in  s.s.b.  service  thinks  first  of  the  power  avail- 
able. If  things  progress  normally,  a  change  occurs. 
At  some  point  he  starts  adjusting  for  linearity  and 
then  accepts  the  power  that  results.  When  that 
happens,  you  know  that  he  has  graduated  into  a 
new  and  mature  attitude  toward  our  old  friend 
Mr.  D.  C.  Plate  Milliammeter.

far  on  the  air,  it  can  still  be  nasty  enough  to  cans 3

simple  matter  to  get  rid  of  the  cUck,  and  two

the  plate  dial  lamp.  The  dummy  lamp  should  also 
light  up  at  this  point.  Don't  expet^t  the  lamp  to  be 
at  full  brilliance.  While  lamp  bulbs  make  a  con- 
venient dummy  antenna,  they  don't  always 
match  the  output  characteristics  of  a  transmitter 
and  consequently  won't  load  the  transmitter 
fully. 

For  40-meter  operation,  a  40-metcr  crystal 
should  be  inserted  in  the  crystal  socket  and  S\ 
switched  to  short  out  the  unused  portion  of  the 
plate  coil.  Tune-up  procedure  is  the  same  as  on 
80  meters. 

It  is  possible  to  use  an  80-meter  crystal  and 
double  in  the  plate  circuit  for  40- meter  operation. 
However,  for  maximum  efficiency,  it  is  best  to 
have  crystals  of  frequencies  that  fall  in  the  band 
in  use. 

To  put  the  rig  on  the  air,  it  is  imperative  that 
an  antenna  coupler  be  used.  The  unit  described 
here  was  given  extensive  on-the-air  tes's.  The 
antenna  coupler  used  was  the  one  described  by 
the  writer  in  QST  for  April,  1955.  The  antenna 
was  135  feet  long,  center-fed  with  open-wire  TV 
line.  Over  70  contacts  in  30  states  were  made  in  a 
4-day  session. 

In  constructing,  testing,  and  using  this  trans- 
mitter or  any  transmitter  for  that  matter,  the 
beginner  should  always  exercise  extreme  caution 
in  dealing  with  electric  power.  Be  sure  and  check 
that  all  voltages  are  off  before  touching  any  of  the 
components  below  deck  and  in  the  shield  box

rigs  capable  of  lieing  removed  and  operated  on 
either  110  v.  a.c.  or  6  v.  d.c.  They  use  19-inch 
vertical  whips. 

The  Aid  Check  Points  are  located  around  the 
perimeter  of  the  heavily-populated  areas.  These 
RACES  stations  utilize  a  unit  with  17  watts  out- 
put to  a  ground-plane  antenna. 

Each  of  the  fifteen  large  townships  in  Erie 
County  has  what  is  called  a  Report  Center.  Each 
Report  Center  has  a  complete  RACES  radio 
station  to  relay  traffic  from  the  local  area  di- 
rectors to  the  main  Control  Center.  These  stations 
at  the  Report  Centers  utilize  10!)-watt  transmit- 
ters feeding  a  beam  antenna  centered  on  the 
Control  Center  in  Lancaster,  N.  Y.  All  antennas 
are  vertically  polarized  for  compatibility. 

All  installations  are  completely  independent  of 
commercial  mains  by  virtue  of  having  a  gasoline- 
driven  a.c.  generator  available  delivering  from  2 
to  5  kilowatts,  depending  upon  requirements. 

Many  of  you  reading  this  article  will  probably 
ask  where  do  the  personnel  to  operate  a  com- 
munications system  of  this  size  come  from.  When 
General  E.  G.  Ziegler,  the  County  Director  of 
Civil  Defense,  originally  outlined  his  require- 
ments for  RACES  communications,  we  knew  that

There  are  fifteen  township  report  centers,  each  re- 
quiring communications.  This  is  the  Elma  Township

amateur  radio  operators  would  the  success  of  this 
program  be  insured.  Today,  two  j-ears  later,  it 
can  honestly  be  said  that  the  local  amateur  radio 
operators  in  Erie  County  have  more  than  justified 
the  faith  the  Erie  County  Board  of  Supervisors 
put  in  them  when  they  authorized  the  expendi- 
ture of  $57,000  for  the  equipment  to  outfit  all  of 
the  RACES  installations  in  the  county.  We  have 
a  total  of  167  licensed  amateur  radio  operators 
enrolled  in  civil  defense  and  cleared  in  accordance 
with  RACES  regulations.  There  are  more  ama- 
teurs signing  up  each  day  and  it  is  hoped  that 
eventually  every  amateur  in  Erie  County  will  be 
actively  participating  in  the  RACES  program 


Operation  Cue

during  the  Operation  Cue  program.  It  takes  more 
than  two  weeks  of  concentrated  study  to  absorb 
more  than  a  smattering  of  information  on  atomic 
onerg}^,  but  most  of  us  observers  felt  we  had  in 
t  hat  two  weeks  jjicked  up  far  more  atomic  energy 
information  than  the  average  person  will  get  in 
his  lifetime.  It  was  an  experience  we'll  never  forget. 
.Vnd  spectacular  as  it  was,  the  explosion  itself 
was  only,  as  FCDA's  Harold  Goodwin  put  it,  the 
attraction  to  get  us  out  there  to  attend  the  brief- 
ings. The  pre-shot  and  post-shot  visits  to  the  test 
area  were  as  important  as  the  witnessing  of  the 
shot  itself,  if  not  more  so.  ARRL  was  present, 
not  only  in  the  person  of  ourselves,  but  in  the 
persons  of  the  man_\-  oth(>r  amateurs  who  attended 
and  took  part.

including  Canada.  These  stations  will  send  at  1 1 :30 
P.M.  their  own  local  time.  .  .  . 

In  Volume  VI,  at  11,  May  1923,  the  short- 
wave "CQ  Party"  was  reported  as  being  a  "de- 
cided success."  Receipt  of  many  logs  was  men- 
tioned; and  QST  stated  that  "surprising  dis- 
tances on  surprisingly  low  waves  were  recorded." 
The  details  were  shown  on  pages  75  to  76,  May 
1923,  under  "Calls  Heard."  Logs  were  received 
from  every  district  except  the  seventh.  The  range 
of  wavelengths  repres3nted  in  the  reports  rani 
from  80  to  190  meters. 

One  result  of  some  unspecified  League  test, 
conducted  in  1923  was  later  recorded  in  a  head- 
note  affixed  to  an  article  by  Dunmore,  reporting: 
some  of  the  work  done  by  the  Bureau  of  Stand- 
ards in  the  short-wave  region.  (See  75  to  77,  July/ 
1923,  which  is  also  in  Volume  VI) : 

.  .  .  Attention  is  also  invited  to  the  fact  that  im 
our  short-wave  tests  6GI  with  a  5-watt  tube  set 
dropped  to  the  suppcsedly  impractical  wave  of  125' 
meters  and  on  both  nights  of  the  test  put  a  roaring, 
signal  into  every  state  in  the  Union.   .   .   . 

On  the  night  of  November  27th,  1923,  trans- 
atlantic amateur  communication  was  first  ac- 
complished. A  wavelength  of  100  meters  was; 
used.  Station  IMO,  at  West  Hartford,  Connec-- 
tic.ut,  with  Traffic  Manager  Schnell  at  the  key,, 
worked  French  SAB  (Leon  Deloy,  of  Nice, 
France^.  Shortly  afterward,  on  the  same  night, 
John  L.  Reinartz  (IXAM,  ex-lQP,  of  South 
Manchester,  Connecticut)  also  worked  SAB.  All 
three  stations  ussd  transmitting  circiits  devised 
bv  Reinartz.  (On  all  of  this,  sse  Volume  VI  of 
QST,  at  9  to  12,  January  1924;  and  26  to  27, 
January  1924). 

Thereafter,  there  was  no  doubt  in  any  ama- 
teur's mind  that  the  use  of  waves  around  100 
meters  in  length,  or  even  shorter,  possessed  DX 
capabilities;  and  that  the  rew^ard  arising  from 
their  us  3  would  be  long-distance  two-way  com- 
munication with  low  power  and  not  simply 
temporary  relief  from  QRM.  The  lure  of  DX  work 
was  irresistible;  and  amateur  developments  in  the 
short-wave  field  followed  very  quickly  —  both  as 
to  transmitting  and  receiving  equipment.

The  Indian  sang  his 
death  song 


-I  r\f\  YEARS  AGO,  during  a  frontier  skir- 
iUUmish,  an  Indian  brave,  singing  his 
own  death  song,  charged  down  on  a  young 
officer.  Lieutenant  George  Crook,  4th  Infan- 
try, coolly  fell  to  one  knee,  carefully  aimed, 
and  dropped  the  brave  in  his  tracks. 

It  was  not  Crook's  first  Indian,  nor  his  last.  By 
the  time  he  made  general,  Crook  was  the  great- 
est Indian-fighter  this  country  has  ever  had. 

Yet,  he  was  also  one  of  the  best  friends  the 
Indians  have  ever  had.  For  he  understood 
them  well,  dealt  fairly  and  firmly,  and  always 
kept  his  promises. 

When  Crook  died,  Indians  wept.  And  a 
Sioux  chief  named  Red  Cloud  said :  "He  never 
lied  to  us.  His  words  gave  the  people  hope." 
No  nation  can  ever  have  enough  men  like 
George  Crook.  But  America  had,  and  still 
has,  a  lot  of  them.  That's  important  to  re- 
member. Because  it  is  a  wealth  of  human 
character  rather  than  a  wealth  of  money  that 
gives  America  its  real  worth.  Just  as  it  is  the 
Americans,  all  160  million  of  them,  standing 
behind  our  country's  Savings  Bonds,  who 
make  these  Bonds  one  of  the  world's  finest 
investments. 

For  your  sake  — and  America's  — why  not 
take  advantage  of  this  fact?  Invest  in -and 
hold -United  States  Savings  Bonds. 


It's  actually  easy  to  save  money -when  you 
buy  United  States  Series  E  Savings  Bonds 
through  the  automatic  Payroll  Savmgs  Plan 
where  you  work!  \ou  just  sign  an  application 
at  your  pay  office:  after  that  your  saving  is 
done  for  you.  And  the  Bonds  you  receive  will 
pay  you  interest  at  the  rale  of  37o  per  year,  com- 
pounded semiannually,  for  as  long  as  19  years 
and  8  months  if  you  wish!  Sign  up  today!  Ur, 
if  you're  self-employed,  invest  in  Bonds  regu-

to  put  your  money,  for  United  States  Savings 
Bonds  are  as  safe  as  America !

What  Is  This  Thing 

Called  the  '*Hiimp'' 

in  CODE? 


X   HE  hump  (around  8  words)  is  the 
thing  that  tells  you  you  have  wasted 
your     time     by     starting    out     wrong. 
Thirty  years  ago  when  we  started  teach- 
ing Code  our  students  too  ran  head-on 

into  the  hump.  We  went  to  work  to  find  out  why.  TWO-PHASE, 
STEP  BY  STEP  instruction  is  the  perfect  answer.  In  this  method 
dotdash  is  not  A.  The  SOUND  resulting  from  dotdash  is  A.  There 
is  also  the  important  factor  of  correct  timing.  If  the  signals  are  not 
timed  correctly  the  resulting  sound  will  not  be  correct.  There  are 
many,  many  things  connected  with  proper  Code  instruction,  many 
of  them  so  small  they  seem  inconsequential.  Others  are  so  technical 
that  many  so-called  experts  fail  to  understand  them.  It's  a  long 
story  but  I  have  it  all  written  up  and  will  be  glad  to  send  it  to  you. 
A  postcard  will  bring  you  the  full  story.

Transmit-Receive  o»  One  Antenna 

WITH    AUTOMATIC    CHANGEOVER 


Here  is  fully  automatic  electronic  antenna  changeover  from 
receiver  to  transmitter  and  vice-versa — Suitable  for  all  power 
applications  up  to  the  legal  limit.  B&W's  new  T-R  switch 
is  ideal  for  voice  operated  SSB — AM  phone  and  break-in 
CW — all  with  one  antenna. 

•  Ends  annoying  antenna  changeover  relay  clatter 

•  Lets  you  select  one  antenna  for  receiving  and 
transmitting — automatically 

•  You  get  actual  signal  gain  from  1   mc  to  35  mc 

•  Broad  band — no  tuning  or  adjustments 

•  Fail-safe  device  protects  final  amplifier,  low-pass 
filter,  shielded  link — antenna  load  is  always 
coupled  to  transmitter 

•  Power  loss  virtually  unmeasurable 

•  Operates  with  either  52   or  75  ohm  coax  line 

•  Compact — completely  self-contained

Provides  accurate  check  points  for  transmitting 
frequency  or  for  calibrating  receivers  and  VFO's! 

Extremely  compact,  this  tiny  crystal  calibrator  provides  accurate 

100  kc.  check  points  to  55  mc.  High  quality,  hermetically  sealed 

military  type  crystal  is  superior  to  those  usually  found  in  a  unit 

of  this  type.  Circuit  uses  a  6BH6  tube  and  has  an  adjustable 

ceramic  trimmer  condenser  for  exact  zero  beating  of  the 

crystal  to  WWV  or  other  standard. 

Measuring  only  IVt"  x  IVi"  x  l'/?",  the  chassis  may  be 
mounted  inside  receiver  cabinet  or  in  any  convenient 
spot.  (Overall  height  to  top  of  tube  is  Sys".)  Power 
may  be  taken  from  your  receiver  or  other  source — 
requires  only  6.3  volts  at  .15  amps,  and  150  to  300 
volts  at  2  ma.  Special  clips  are  provided  for  tube 
prongs  of  equipment  furnishing   power  take-off. 
Power  cable  and  extension  leads  are  included  to 
permit  remote  mounting  of  switch.  Furnished  com-

Editor,  QST: 

For  years  it  has  been  a  pleasure  to  scan  the  diagrams 
printed  in  QST.  That  is,  until  recently  —  the  henscratcliing 
which  seems  to  be  the  current  vogue  could,  in  my  opinion, 
provide  satisfaction  only  to  a  power  engineer  or  an  Egyptian 
stone  cutter. 

If  this  is  progress  I,  for  one,  would  prefer  to  remain  static 
in  this  instance  and  let  the  power  people  conform  to  the 
communication  standard  if  they  should  so  desire.  If  not,  let 
them  wallow  in  a  maze  of  hieroglyphics  and  leave  us  be.

I  cannot  understand  what  all  the  fuss  over  the  new  sym-

Any  move  to  keep  the  ham  informed  is  a  good  one,  in  my  es- 
timation. Would  suggest  to  draftsmen  that  larger  dots  at 
junctions  would  be  easier  for  the  eye  to  follow  a  circuit.  .  .  .

vdce  to  these  people  is  (censored] !  The  new  symbols  are  cer-

'  OR  more  than  forty  years,  the  Ameri- 
can Radio  Relay  League  has  been  the 
amateur's  own  organization,  operating 
under  policies  established  by  directors  of 
his  choice,  serving  as  a  clearing-house  for 
information,  representing  him  at  inter- 
national conventions,  before  Federal 
agencies  and  national  groups,  and  pro- 
viding other  services  to  make  his  hobby 
enjoyable  as  well  as  useful. 

f  f  /embers  of  the  League  in  eight  ARRL 
Divisions  will  soon  be  nominating  and 
voting  for  the  directors  who  will  represent 
them  for  the  next  two  years.  Every  amateur 
taking  part  in  these  elections  helps  further 
the  aims  and  protects  the  privileges  he  has 
as  a  ham.  Naturally,  only  League  mem- 
bers vote  in  ARRL  elections.  Let  your 
voice  be  heard — sign  up  now.

39  Sobro  Avenue 
Valley  Stream,  N.  Y. 
Editor,  QST: 

Read  W0PDN's  letter  in  May  QST  with  considerable  in- 
terest. He  refers  to  an  ET2  station.  ...  I  don't  think  that 
W0PDN  has  much  experience  in  the  QSL  rackets  as  they 
exist  today.  Tliis  station  is  one  of  a  number  of  rare  ones  that 
periodically  show  up  on  the  bands  and  work  .5-600  stations, 
mostly  VVs  and  then  never  QSL  —  except  to  DX  editors  and 
prominent  liams,  for  obvious  reasons.  Now  .  .  .  my  ques- 
tion is:  What  do  they  do  witli  tlie  International  Reply  Cou- 
pons? 

—  Theodore  J.  Seiter,  W2FJH 

P.  O.  Chileka 
Nyasaland 
Editor,  QST: 

I've  had  more  than  a  little  correspondence  with  various 
stations,  mostly  Ws,  who  have  sent  me  QSLs,  claiming 
QSOs  which  have  not  taken  place.  I  have  returned  the  cards 
to  the  senders. 

Some  time  ago,  I  informed  W9BRD  of  the  stations  who 
qualify  for  my  blacklist.  Maybe  it's  a  coincidence  tliat  these 
hopeful  QSL  seekers  make  up  the  greater  part  of  this  list. 

One  W3  gentleman  waxed  indignant  in  a  letter  to  me, 
after  I  had  returned  his  card.  In  it,  he  states  that  DX  sta- 
tions only  reply  to  the  "kw.  and  beam"  fraternity  and  that 
W  QRP  stands  no  chance  of  working  the  DX.  If  he  had  the 
opportunity  of  scanning  my  QSL  files,  he  would  see  that 
over  half  my  W  cards  are  for  QSOs  with  stations  using  150 
watts  and  less.  This  self-same  VVS  was  responsible  for  ruining 
a  QSO  with  a  much  wanted  EA8,  by  carefully  zeroing  the 
latter  and  calling  me  as  I  stood  by  to  pull  the  E.48  through 
the  racket.  How  crazy  can  one  get? 

To  cap  it  all,  this  W3  fella  says  "  why  do  you  work  a  W 
more  than  once  and  why  don't  you  keep  the  QSOs  snappy 
when  there  are  lots  waiting?"  It  would  be  funny  if  it  weren't 
tragic.  As  an  example  from  my  log  on  Nov.  16,  1954,  I 
worked  47  W  fellas  in  1 10  minutes.  If  that  isn't  good  enough, 
I'll  apologize  for  being  a  slow  operator.  As  for  the  number 
of  times  I  QSO  any  particular  W,  I  guess  that's  my  business. 
There  are  some  Ws,  in  particular,  with  whom  a  QSO  is  a 
pleasure  indeed,  when  I  feel  like  more  than  a  mere  exchange 
of  RSTs  and  73. 

Finally,  j  ust  a  reminder  —  let's  not  forget  that  remote 
stations  are  keen  on  DX  themselves  and  do  not  exist  solely 
to  provide  fun  for  Ws  and  Gs.  I've  held  VS7,  VSl  and  G 
calls  since  the  end  of  '45  and  therefore  have  been  on  both 
sides  of  the  DX  fence.  It's  flogging  a  dead  horse,  I  know,  but 
how  fine  it  would  be  if  the  over-eager  beavers  would  be  a 
little  more  patient  and  keep  their  fingers  off  the  bug  until 
they  know  the  DX  station  is  ready  for  a  call. 

That's  my  little  piece.  Good  huntin'  to  the  savvy  boys  and 
may  the  others  learn  the  error  of  their  way.

Editor,  QST: 

I  read  witli  interest  the  article  on  TV  servicing  in  the  June 
issue  of  QST .  Wliile  I  realize  that  QST  is  supposed  to  be  "of, 
by  and  for  the  radio  amateur,"  I  think  such  articles  are 
timely  and  of  interest  to  a  large  portion  of  the  ham  frater- 
nity. ... 

I  think  more  such  articles  from  time  to  time  would  im- 
prove QST.

territory,  but  tliis  one  is  certainly  one  of  the  best  in  QST  for 
some  time,  and  this  i.ssue  will  be  especially  marked  on  the 
binding,  as  arc  some  others,  for  ready  reference.  I  tliink  that 
space  in  QST  was  very  well  used.

Leading  J^mateur  Designs 

: .  .USE  RCA  TUBES 


You  are  looking  at  the  business  end  of  a  Harvey-Wells 
T-90  Transmitter/In  this  "final"  an  RCA-6146  beam  power 
tube  delivers  the  signal  punch  that  gives  this  transmitter 
its  reputation  for  ability  to  "get  out." 

Here's  why  RCA  high-perveance  beam  power  tubes,  like 
the  6146,  are  preferred  by  leading  designers  of  amateur 
and  commercial  transmitters. 

RCA  beam  power  tubes  make  it  practical  to  use  fewer 
components;  fewer  tuning  controls— /ei^'^r  stages.  They  lend 
themselves  to  bandswitching  circuits  — take  full  plate  input 
with  smaller  drivers  (a  big  help  in  reducing  TVI).  RCA 
beam  power  tubes  give  you  the  power  you  want  at  lower 
plate  voltages. 

RCA  High-Perveance  Beam  Power  Tubes  are  available 
at  your  RCA  Tube  Distributor— for  amateur  transmitters 
having  input-power  ratings  up  to  a  "gallon."  For  technical 
data  on  any  specific  beam  power  tube  type  including  the 
6146,  write  RCA,  Commercial  Engineering,  Section  H37M,

It  Seems  to  Us... 


HELPING  NEWCOMERS 

Here  it  is  September  again  —  our  vacations 
are  over,  the  ol'  swimmin'  hole  has  lost  some 
of  its  grip  on  us,  the  sununer  QRN  has  started 
to  fade  away.  Our  thoughts  turn  once  agam 
to  active  hamming;  the  local  club  gets  gomg 
again  in  full  swing.  It  seems  tune  for  a  re- 
minder of  a  couple  of  related  worth-while 
projects  for  the  local  gang  to  tackle. 

Hams  have  long  held  out  a  helping  hand  to 
newcomers  on  an  individual  basis.  In  the  past 
few  years,  more  and  more  radio  clubs  have 
been  offering  formal  courses  in  amateur  radio 
for  beginners,  with  club  members  sharing  the 
teaching  tasks.  Prospective  hams  have  been 
attracted  to  the  courses  by  notices  m  the 
papers,  in  schools,  and  at  Scout  and  civic 
club  meetings.  Now  is  a  good  time  for  your 
club  to  start  laying  plans  for  this  year's  course. 
If  help  is  needed,  the  Communications  De- 
partment of  ARRL  offers  assistance  in  the 
form  of  code-practice  schedules,  course  out- 
lines, and  training  aids.  Whether  or  not  you 
ask  for  aid,  however,  the  Communications 
Department  would  like  to  know  about  your 
course  so  that  other  newcomers  in  your  area 
can  be  steered  your  way. 

A  closely-related  project  is  the  setting  up 
of  a  committee  to  conduct  examinations  for 
Novice,  Technician  and  Conditional  Class  as- 
pirants. As  earlier  editorials  pointed  out,  it 
is  important  that  these  "mail"  examinations 
be  conducted  with  uniform  standards,  to  en- 
sure that  only  qualified  people  obtain  licenses, 
and  to  ensure  that  all  applicants  have  equal 
opportunity.  The  objective  can  best  be  ac- 
compUshed  by  appointing  mature,  qualified 
amateurs  to  serve  on  examination  committees 
in  every  club  throughout  the  country.  This 
system  has  an  advantage  over  the  use  of 
individual,  uncoordinated  examiners,  however 
qualified  they  may  be  personally,  in  that 
prospective  amateurs  can  be  notified  through 
the  press,  radio  and  other  media  mentioned 
above  of  the  time  and  place  of  the  tests. 

FCC  has  expressed  {QST,  September,  1954, 
page  9)  the  hope  that  all  clubs  will  establish 
such  committees.  The  District  Engineers  are 
anxious  to  know  when  these  groups  go  into 
operation  and  are  always  ready  to  assist  in 
getting  them  started.  It  may  be  possible  for 
committees  to  keep  a  supply  of  application 


blanks  and  test  papers  on  hand,  speeding  the 
licensing  process  considerably  for  anxious  ap- 
pUcants. 

Every  activity  needs  new  blood,  and  these 
two  projects  will  help  to  assure  the  continuing 
flow  of  eager  newcomers  into  amateur  radio. 
Here's  your  chance  to  train  new  operators  the 
way  they  should  be  trained,  and  build  up  the 
club  at  the  same  time. 

WHICH  CALL  TO  SIGN? 

As  we  hams  are  a  thoroughly  fraternal 
bunch,  it  is  hardly  news  that  many  new- 
licensees  quickly  take  up  the  pleasant  custom 
of  station-visiting.  But  our  correspondence 
recently  indicates  a  misunderstanding  on  one 
aspect  — what  call  does  WIAAA  sign  when 
he  is  visiting  WlBBB? 

There's  only  one  answer.  When  operating 
another  ham's  station,  you  sign  his  station 
call,  not  your  own  personal  stations  call. 
You  can  indicate  in  the  course  of  conversation 
that  your  own  station  is  WlAAA,  but  that's 
pure  conversation  and  not  part  of  the  signing 
procedure.  The  call  you  sign  for  the  station  s 
operation  is  WlBBB.  And  of  course  the  data 
goes  into  the  station's  log,  not  your  own 
back  home. 

We  should  perhaps  remind  you  that  a  sta- 
tion may  be  operated  only  within  the  privileges 
available  to  both  operator  and  station  license. 
For  example,  Novice  \\^1AAA  can  visit 
General  Class  WlBBB  and  operate  the  latter 
station,  but  only  in  the  Novice  bands,  using 
crystal-control,  and  75  watts  or  less  input. 
The  call  to  be  signed  is  WlBBB.  The  General 
Class  operator  can  pay  a  return  visit  and 
operate  ^\"N1AAA,  of  course  signing  that  call, 
but  again  only  under  Novice  privileges.  It 
would  not  be  proper  for  the  General  Class 
operator  to  operate  the  Novice-licensed  sta- 
tion by  signing  his  personal  station  call  in  other 
than  Novice  bands.  Nor  can  he  use  VFO  or 
more  than  75  watts  input  at  the  Novice  station 
on  the  theory  that  he  is  licensed  for  such 
operation;  surely  he  is,  but  the  Novice's  station 

Keep  up  the  visiting,  OMs,  but  remember 
that  you  sign  the  call  of  the  station  being 
visited,  and  are  Umited  by  the  scope  of  its 
station  license  and  your  operator  license, 
whichever  privileges  are  the  lesser.

W7GND  has  come  up  with  an  easier  way  of 
modifying  the  1625  tetrodes  used  in  the  "200- 
Watt  Linear  amplifier,"  June  QST. 

He  found  that  the  cathode  and  suppressor 
leads  are  brought  out  to  the  tube  pin  in  the  Na- 
tional Union  type  1625.  By  driUing  a  ^  inch  hole 
in  the  side  of  the  tube  above  the  cathode  pin  and 
one  over  an  unused  pin,  the  suppressor  wire  can 
be  unsoldered  from  the  cathode  and  connected 
to  the  unused  pin. 

In  order  to  determine  which  lead  is  the  cathode 
and  which  is  the  suppressor,  the  filament  is 
lighted  and  the  electron  flow  from  each  of  the 
unknown  wires  to  the  plate  is  measured.  The 
combination  with  the  larger  current  determines 
the  cathode  lead,  while  the  other  is  the  supressor.

Amateur  Communication  Using  Solar  Power

to  visualize  a  future  of  ultra-compact

then  bolted  to  a  bracket  on  a  ball  and  socket

The  "2B3"  Superheterodyne 

A  Simple  "Minimum"  Receiver  for  80  and  40  Meters 
BY  BYRON  GOODMAN,  WIDX 


THE  title  of  this  article  has  no  more  justifica- 
tion than  that  it  identifies  a  particular  de- 
sign and,  if  you  know  the  code  we  just 
invented,  it  signifies  a  "2-band  3-tube"  super- 
heterodyne. It  is  the  dull  end  result  of  looking 
around  for  a  title  to  describe  a  little  super- 
heterodyne that  will  serve  anyone  quite  well  as 
his  first  ham-station  receiver. 

This  receiver  started  out  as  an  attempt  to  build 
a  practical  two-band  receiver  that  would  more 
than  hold  its  own  with  anything  selling  for  thirty 
dollars.  No  attempt  was  made  to  make  it  an 
"all-band"  affair  —  we  figured  we  were  licked 
from  the  start  in  that  department.  But  by  con- 
fining the  tuning  range  to  two  amateur  bands, 
we  knew  it  would  be  possible  to  build  in  operat- 
ing features,  such  as  adequate  bandspread  and 


•  The  receiver  described  on  these  pages 
is  called  a  "minimum"  receiver  by  the 
author  because,  in  his  opinion,  it  rep- 
resents the  minimum  in  receiving 
equipment  that  will  give  a  good  account 
of  itself  under  present  band  conditions. 
The  simple  construction  makes  it  an  easy 
matter  to  duplicate  the  receiver. 


lating)  state,  hoping  that  the  resultant  selectivity 
would  be  sufficient  for  adequate  single-signal  c.w. 
reception.  It  wasn't,  and  it  was  also  observed 
that  the  6U8  pentode  section  used  as  the  re- 
generative detector  was  a  little  more  microphonic 
than  we  care  to  have  such  things,  so  a  6BD6 


This  two-band  superhetero- 
dyne receiver  uses  an  auto- 
dyne  second  detector  and  ad- 
justable antenna  coupling.

good  stability,  that  are  quite  hard  to  come  by  in 
an  inexpensive  all-band  commercial  job.  We 
started  out  with  three  dual  triodes:  one  as  a 
mixer-oscillator,  one  as  a  detector-b.f.o.,  and 
the  third  as  a  two-stage  audio  amplifier.  In- 
vestigating selenium-rectifier  vs.  tube-rectifier 
power  supplies,  it  was  found  that  the  latter  was 
cheaper.  The  dual  triodes  were  6SN7s,  because 
the  sockets  for  these  tubes  are  cheaper  than  those 
for  the  miniature  tubes.  But  the  performance  of 
the  finished  product  didn't  come  up  to  our  e.x- 
pe(;tations  —  the  triode  mixer  was  touchy  and 
the  detector-b.f.o.  combination  didn't  behave  as 
had  been  hoped.  The  original  objective  of  abso- 
lute rock-bottom  cost  was  scrapped,  and  w^e 
turned  to  the  use  of  miniature  tubes.  Here  a  log- 
ical choice  for  mixer-oscillator  and  detector- 
b.f.o.  seemed  to  be  the  6U8  triode-pentode.  A 
homemade  1700-kc.  i.f.  transformer  was  substi- 
tuted for  the  commercial  unit  previously  used, 
but  again  we  weren't  satisfied  with  the  detector! 
We  were  using  it  in  a  regenerative  (but  nonoscil- 


oscillating  detector  was  substituted.  Although 
the  original  objective  of  single-signal  reception 
had  to  be  given  up,  the  resultant  receiver  turned 
out  to  be  a  husky  little  gentleman  in  every 
other  respect.  The  over-all  gain  was  enough  to 
rattle  the  daylights  out  of  a  pair  of  high-im- 
pedance headphones,  the  stability  was  good, 
and  the  receiver  will  stack  up  well  against 
anything  in  its  price  class  ($.35)  or  slightly  higher. 
Now  that  the  inherent  modesty  of  the  author 
has  been  demonstrated,  let's  get  down  to  details. 

The  Circuit 

While  few  will  argue  about  the  sensitivity  of 
an  autodyne  detector,  anyone  who  has  worked 
with  one  knows  that  the  loading  is  critical,  and 
an  antenna  swinging  in  the  breeze  may  "pull" 
the  frequency.  Then,  too,  the  regeneration 
control  setting  may  need  changing  as  one  tunes 
a  band.  Using  an  autodyne  detector  at  a  low  fixed 
frequency  obviates  these  shortcomings  but  dic- 
tates  a   superheterodyne   type   of   receiver.    By

limiting  the  frequency  range  of  the  receiver  to 
two  consecutive  amateur  bands  and  using  an  i.f. 
of  half  the  frequency  difference  l)etvveen  the 
two  bands,  it  is  possible  to  "change  bands' 
simply  by  tuning  the  input  circuit  to  the  one 
l)and"or  the  other.  For  example,  with  the  high- 
fiequencv  oscillator  tuned  to  5.3  Mc,  and  the 
i  f  at  1700  kc,  the  receiver  responds  to  either 
a  3.6-Mc.  signal  (5.3  -  3.6  =  1.7)  or  a  7.0-Mc. 
signal  (7.0  -  5.3  =  1.7),  depending  upon  the 
tuning  of  the  mixer  grid  circuit.  It  is  a  convenient 
arrangement  that  pernuts  building  a  bandspread

Referring  to  the  circuit  in  Fig.  1,  it  can  be  seen 
that  adjustable  input  coupling  is  provided 
(variable  coupling  between  Li  and  L2).  While 
the  signal  level  can  be  reduced  by  detuning  the

mixer  input  circuit  is  tuned  close  to  the  oscillator 
frequency,  a  condition  that  is  never  used. 

The  1700-kc.  i.f.  transformer  (L5  and  Le 
and  the  associated  shunt  capacitors)  uses  two 
of  the  compact  ferrite-cored  b.c.  antenna  coils 
that  have  become  popular  recently.  They  have 
the  twin  virtues  of  low  cost  and  quite  adequate 
Q  for  this  job.  The  regenerative  detector  uses 
the  Colpitts  circuit  to  eliminate  the  need  for 
tapping  the  coil  or  adding  a  tickler  winding.  An 
electrolytic  capacitor  across  the  regeneration 
control  eliminates  the  noise  produced  by  varying 
the  wire-wound  potentiometer.  This  potentiom- 
eter was  selected  instead  of  a  composition  affair 
because  of  a  personal  preference  for  such  controls 
wherever  any  significant  current  is  involved. 

The  two-stage  audio  amplifier  is  conventional, 
except  that  we  started  out  with  no  cathode  by- 
pass capacitors  and  found  that  the  one  shown  on 
the  first  stage  reduced  some  a.c.  hum.  The  a.c. 
switch,  Si,  is  mounted  on  the  audio  volume 
control. 

Construction 

An  8  X  12  X  3-inch  aluminum  chassis  plus  a 
7  X  13-inch  panel  provides  enough  metal  for  the 
receiver,  with  the  single  exception  of  the  scrap 
of  aluminum  needed  for  the  bracket  that  sup- 
ports the  15-;uyuf.  tuning  capacitor,  C2.  The  panel 
is  held  to  the  chassis  by  the  two  shaft  bearings 
and  the  regeneration-control  potentiometer,  as 
can  be  seen  in  one  of  the  photographs.  It  will  pay 
oflf  to  take  a  little  care  in  the  location  of  the  holes 
for  the  National  type  K  dial,  in  the  interests  of  a 
smooth-tuning  receiver.  We  built  the  tuning- 
capacitor  bracket  first,  hned  up  the  capacitor 
shaft  against  the  panel  to  mark  the  dial  bushing 
hole,  and  then  used  the  template  that  comes  with 
the  dial  to  locate  the  drive  bushing  hole.  The 
small  knob  that  comes  with  the  Type  K  dial  was 
replaced  by  a  large  one,  and  a  couple  of  drops  of 
oil  were  used  to  lubricate  the  drive  bushing. 

Practically  everything  else  in  the  receiver  can 
be  located  from  the  photographs,  but  we  will 
touch   on   one   or  two   points.    The  adjustable 
antenna-coupling  coil  was  mounted  on  the  end 
of  a  length  of  ^-inch  diameter  Incite  rod  by 
cutting  the  end  of  the  rod  at  45  degrees  and 
cementing  a  small  scrap  of  polystyrene  sheet  to 
this  face.  The  scrap  was  then  filed  to  fit  inside 
the  coil  and  secured  with  a  few  drops  of  Duco 
cement.    Four  small   holes  are  drilled   through 
the  rod:  two  for  the  coil  ends  (which  also  serve 
as  tie  points  for  the  flexible  antenna  and  ground 
leads),    one    through    which    the    antenna    and 
ground  leads  are  threaded  and  cemented,  and 
the  fourth  through  which  a  piece  of  No.  20  wire 
is  pushed  and  bent  back  around  the  rod.  This  last 
wire  serves  as  a  shoulder  that  bears  against  a 
fiber    (or    metal)    washer    that    in    turn    bears 
against  a  large  rubber  gronamet  with  a  M-inch 
hole,  as  shown  in  Fig.  2.  The  other  side  of  the 
grommet  has  another  washer  between  it  and  the 
panel  bushing.  The  rod  is  pushed  through  the 
bushing,  two  more  washers  are  added,  and  then 
the  knob  is  put  on.   By  pushing  the  rod  out 


through  the  panel  as  the  knob  is  tightened,  the 
rubber  grommet  is  left  in  compression,  and  it 
serves  as  a  simple  friction  lock  for  the  control. 
It  almost  takes  longer  to  describe  the  gadget 
than  it  does  to  build  it. 

The  two  coils  Ls  and  Le  are  mounted  on 
1-inch  separated  centers.  The  "phones"  jack  is 
insulated  from  the  chassis  by  fiber  washers.  Both 
C2  and  Ci  capacitors  are  insulated  from  the 
chassis  —  the  former  by  mounting  it  with  short 
bushings  on  the  mounting  bracket,  and  the  latter

by  fastening  it  to  the  chassis  with  a  machine 
screw  through  small  extruded  fiber  washers. 
Clearance  holes  for  leads  from  both  stators  and 
rotors  of  these  capacitors  were  provided,  as  can 
be  seen  in  the  photographs.  For  those  who 
question  the  author's  sanity  in  going  to  this 
trouble  to  provide  for  rotor  leads  that  could 
be  made  by  simply  anchoring  the  rotors  to  the 
chassis,  we  hasten  to  point  out  that  one  of  our 
pet  tricks  is  to  provide  short  and  single  r.f. 
paths  for  circuits  that  are  sometimes  left  to 
chance.  In  several  instances  it  has  apparently 
added  considerably  to  the  stability  of  oscillators, 
and  we  now  do  it  as  a  matter  of  course. 

The  only  other  touch  someone  might  argue 
with  is  the  shielded  leads  to  and  from  the  volume 
control.  These  pass  through  a  grommet  in  the 
chassis  and  make  connection  to  the  chassis  only 
at  the  12AX7  socket.  This  is  a  precaution  that 
reduces  hum  in  some  cases  where  there  are 
heavy  a.c.  chassis  currents.  The  lead  from  the 
arm  of  the  regeneration  control  was  shielded  also, 
in  an  effort  to  confine  the  1700-kc.  energy  to  the 
vicinity  of  the  detector. 

Alignment 

Assuming  that  the  wiring  is  correct,  that  the 
tube  heaters  light  when  you  turn  on  the  set, 
and  that  the  power  supply  delivers  250  to  300 
volts,  the  first  step  is  to  check  the  detector. 
This  is  conveniently  done  with  the  6U8  out  of 
its  socket  —  then  if  something  is  wrong  in  the 
"front  end"  it  won't  confuse  the  detector  check- 
mg.  With  headphones  plugged  in  and  the  receiver 
(less  6U8)  warmed  up,  advancing  the  volume 
control  should  give  a  hissing  sound  in  the  head- 
phones. Advancing  the  regeneration  control  (in- 
creasing the  voltage  on  the  6BD6  screen)  you 
should  _  find  a  point  where  the  hiss  increases 
appreciably  and  perhaps  a  very  slight  hum  is

heard    This   is   the   point   where   the   detector 
"oscillates"  — below  this  point  you  wont  get 
a  beat  note  with  c.w.  signals,  and  beyond  it  you 
will    The  detector  works  —  the  next  step  is  to 
get  it  on  1700  kc.  (If  it  doesn't  work,  check  your 
wiring  and  the  voltages  at  the  6BD6  and  12AX7 
Dins)  If  you  can  beg,  borrow  or  steal  a  test 
generator,  it  is  a  cinch  to  put  the  detector  on 
1700  kc.  by  adjusting  the  slug  in  Le  until  the 
1700-kc.  signal  is  heard.  The  test  signal  need 
only  be  loosely  coupled  to  Le-a  wire  placed  a 
foot  from  the  coil  and  connected  to  the  test 
generator  should  suffice.  Lacking  the  test  gener- 
ator  you  may  be  able  to  use  a  b.c.  receiver  by 
tuning  it  to  around  1245  kc  If  the  receiverhas  a

and  if  the  b.c.  receiver  is  placed  within  a  few  feet 
of  the  receiver  under  test,  there  will  be  enough 
radiation  from  the  b.c.  receiver  to  act  as  the  test 
signal.  Don't  go  by  the  caUbration  on  the  b.c.

When  the  autodyne  detector  is  working  satis- 
factorily and  you   have  acquainted  yourself  a 
Httle  with  its  operation,  plug  in  the  6U8  and  let 
it  warm  up.  Trim  U  until  you  find  a  point  where 
it  pulls  the  detector  out  of  oscillation,  and  detune 
it  slightly  until  regeneration  starts  about  10  or 
15   degrees   farther   along   on   the   regeneration 
control,  Ri,  than  it  did  when  U  was  tuned  well 
off  the  frequency.  Check  again  to  make  sure  that 
you  are  still  on  or  close  to  1700  kc.  „  ^    ,

capacitor  on  80  or  40  meters,  tune  around  with 
the  TUNE  capacitor,  C2,  until  you  locate  some 
amateur  signals.  If  you  lack  a  frequency  standard 
or  the  ability  to  borrow  one,  you  have  no  al- 
ternative but  to  identify  the  bands  by  the  linuts 
of  'phone  or  c.w.  signals  in  the  various  subbands. 
In  any  event,  once  you  have  found  the  signals, 
you  can  move  the  bands  on  the  TUNE  scale  by 
changing  the  setting  of  the  mica  compression 
trimmer.  However,  unless  the  i.f.  is  exactly  on 


1700  kc,  the  7.0-  and  3.6-Mc.  points,  7.1  and 
3  7  Mc  etc.,  won't  coincide  as  they  do  on  the 
homemade  scale  shown  in  the  photograph. 
Observing  the  error,  however,  you  can  brmg  the 
if  to  1700  kc  easily.  Incidentally,  the  home- 
made scale  is  simply  a  sheet  of  white  paper  held 
down  with  black  Scotch  Tape,  with  a  shver  of 
tape  on  the  dial  to  serve  as  a  pointer.  The 
pointer  laps  over  the  "O"  end,  and  the  0-100 
scale  of  the  dial  can  stiU  be  used  for  logging  by 
referring  it  to  the  upper  edge  of  the  lower 
horizontal  black  strip  on  the  right-hand  side. 

Operation 

For  the  reception  of  c.w.  signals,  the  regener- 
ation control  is  advanced  far  enough  for  the 
detector  to  oscillate,  as  indicated  by  the  sudden 
increase  in  hiss.  It  may  be  noticed  that  on  strong 
signals  it  is  impossible  to  tune  in  a  signal  at  a 
low  beat  note  (200  to  300  cycles).  This  mdicates 
that  the  signal  is  too  strong  and  is  "pulling 
or  "blocking"  the  detector.  To  overcome  this, 
increase  the  regeneration  control  or  reduce  the 
antenna  coupling.  After  you  have  used  the  re- 
ceiver for  a  while,  you  will  get  used  to  the  teei 
of  it  and  you  will  find  the  settings  that  work 
best  for  various  QRM  levels. 

When  receiving  a.m.  'phone,  the  regeneration 
control  is  maintained  just  below  the  oscillation 
point    It  will  soon  be  noticed  that  this  is  the 
most  sensitive  point  for  'phone  reception,  since 
the  gain  of  the  detector  decreases  as  you  back 
off    the    regeneration    control    stiU    more.    The 
selectivity  of  the  receiver  for  'phone  reception 
is  not  as  great  as  can  be  expected  from  a  small 
superheterodyne  using  several  tuned  circuits  in 
a  455-kc.  i.f.  ampUfier.  However,  you  can  make 
up  a  lot  of  this  selectivity  by  decreasing  the 
antenna  coupling  and  running  the  detector  just 
under  the  oscillation  point.  A  strong  signal  de- 
creases the  selectivity  of  the  regenerative  de- 
tector, hence  the  need  for  reducing  the  signal 
by  decreasing  the  antenna  coupling.  S.s.b.  'phone 
is  received  the  same  as  a  c.w.  signal,  by  advancmg 
the  regeneration  control  past  the  oscillation  point 
and  tuning  carefully  about  the  signal  until  it 
becomes    intelligible.    Overload    is    again    your 
enemy  here,  so  run  the  antenna  coupling  at  a 
value  consistent  with  good  signal/noise  ratio. 


The  mixer  input  and  high- 
frequency  oscillator  coils  are 
mounted  on  tie  points,  as 
shown  here.  The  antenna  coil, 
Li,  is  mounted  on  the  end  of  a 
piece  of  lucite  rod,  as  shown 
here  and  in  Fig.  2.  The  leads 
to  it  are  wrapped  several  times 
around  the  rod,  to  provide  a 
"pig  tail"  connection.

Upper- Air  Conditions  for  Two -Meter  DX 

Temperature  and  Water-Vapor  Content  Soundings 
for  Some  Famous  Dates 


BY  JAMES  S.  COLLIER.*  W20BB 


THE  v.h.f.  man  is  well  aware  that  a  "tem- 
perature inversion,"  "steep  water  vapor 
gradient"  or  some  such  thing  is  necessary 
for  tropospheric  propagation  of  his  signals  over 
extraordinary  distances. 

W2BAV  in  his  article,  "Painless  Prediction 
of  Two-Meter  Band  Openings"  {QST,  October, 
1919),  pointed  out  the  correlation  between  sur- 
face weather  conditions  and  some  good  2-meter 
openings.  Similarly,  this  article  will  show  the 
vertical  distribution  of  temperature  and  moisture 
for  times  of  good  2-meter  DX. 

Consider  first  the  variation  of  temperature 
and  water  vapor  wnth  height  as  shown  in  Fig.  1. 
There  are  no  temperature  inversions  (that  is,  an

sharp  changes  in  the  water  vapor  curve  —  just  a 
steady  decrease  with  altitude  from  a  maximum  at 
the  earth's  surface. 

If  a  radio  wave  is  to  remain  near  the  earth's 
surface  and  not  be  lost  to  outer  space,  some  down- 
ward refraction  is  necessary.  There  would  be  no 
v.h.f.  DX  with  the  average  sounding  of  Fig.  1, 
but  the  refraction  under  such  conditions  is  suf- 
ficient to  extend  the  v.h.f.  range  somewhat  be- 
yond the  line  of  sight.  A  condition  known  as 
superrefraction  (that  is,  more  than  ordinary  re- 
fraction) is  needed  for  real  tropospheric  DX.

'  An  inversion  is  sometimes  considered  to  exist  if  the  tem- 
perature lapse  rate  (decline  in  temperature  with  altitude) 
is  less  than  3  degrees  Fahrenheit  for  1000  feet  of  altitude.

•  Most  v.h.f.  operators  develop  weather 
consciousness  before  they  have  been  in 
the  game  very  long.  They  know  that  the 
daily  weather  maps  can  give  indications 
of  possible  favorable  propagation.  Here 
W2QBB  shows  the  actual  upper-air  con- 
ditions needed  for  2-nieter  DX,  and 
presents  some  soundings  taken  in  areas 
where  long-distance  contacts  were  made. 


Now  that  we  have  seen  what  won't  produce 
2-meter  DX,  let's  look  at  a  sounding  that  has  a 
superrefracting  layer  in  it.  Fig.  2  is  a  plot  of  an 
actual  upper-air  sounding  obtained  at  Johet, 
Illinois,  on  September  6,  1950.  The  data  were  ob- 
tained from  a  radiosonde  instrument  released  at 
2200  EST.  The  moisture  content  of  the  air  is 
shown  by  plotting  the  ratio:  grams  of  water 
vapor  per  kilogram  of  dry  air.  This  is  called  the 
mixing  ratio.  In  this  sounding  and  those  to  fol- 
low, the  altitude  scale  shows  the  height  above 
sea  level  of  the  significant  points.  Therefore,  the 
first  point  on  a  curve  is  at  the  elevation  above  sea 
level  of  the  station  and  not  necessarily  at  zero

Fig.  4  —  Some  idea  of  the  upper-air  conditions  at

soundinfr  made  at  Nashville,  Tenn.,  on  October  30,  1950, 
at  2200  EST.  The  water-vapor  gradient  at  5000  feet  was 
more  than  four  times  that  necossarv  for  superrefraction 
when    Vi4irirK    worked    \\3NK  M,'  Pittsburgh,    Penna. 


In  Fig.  2,  the  temperature  at  the  inversion  AB 
is  seen  to  increase  from  13°C  to  18°C  through 
an  altitude  difference  of  800  feet.  The  gradient  is 
therefore  (18-13) /8  =  O.C°C  per  100  feet  and  is 
insufficient  for  superrefraction.  At  CD  on  the 
water-vapor  curve,  there  is  a  decrease  from  6.2 
grams  per  kilogram  to  1.9  grams  per  kilogram 
through  an  altitude  difference  of  -100  feet.  The 
gradient  is  (6.2-1.9) /4  =  1.1  grams  per  kilogram 
per  100  feet,  giving  us  a  level  of  superrefraction. 

Now  let's  see  how  some  soundings  check  out 
with  various  2-meter  band  openings. 

On  the  evening  of  September  6,  1950,  W2NLY, 
Oak  Tree,  New  Jersey,  worked  W9EQC,  Aurora, 
Illinois,  a  distance  of  nearly  750  miles.  The  near- 
est available  sounding  for  the  eastern  end  of  this 
path  is  one  made  at  Albany,  New  York.  It  is 
shown  in  Fig.  3.  The  sounding  of  Fig.  2,  already 
discussed,  is  representative  of  conditions  at  the 
western  end  of  the  path. 

On  October  30,  1950,  W4HHK,  Collierville, 
Tennessee,  contacted  W3NKM,  Pittsburgh, 
Pennsylvania,  about  650  miles.  The  Pittsburgh 
sounding  is  plotted  in  Fig.  5,  while  the  Nashville, 
Tennessee,  sounding  in  Fig.  4  shows  the  probable 
conditions  at  Collierville.

Fig.  7  —  This  sounding  made  at  Charleston,  S.  C,  on

South  Carolina  contact  was  not  made  in  spite  of  good 
conditions  in  the  northern  stales.  Only  weak  tempera- 
ture and  water-vapor  gradients  are  evident. 


In  none  of  these  soundings  do  the  temperature 
inversions  meet  the  criterion  for  superrefraction, 
but  in  every  case  there  is  a  superrefracting  water- 
vapor  gradient. 

With  only  surface  weather  data  available 
to  him,  W2BAV  expressed  the  view  that  a 
South  Carolina-Michigan  contact  was  apparently 
missed  for  lack  of  activity  on  July  23,  1949. 
While    Michigan   conditions   were  favorable   as

shown  by  the  Toledo,  Ohio,  sounding  in  Fig.  6, 
conditions  in  South  Carolina  were  something 
different.  The  Charleston  sounding  (Fig.  7)  does 
not  show  any  water-vapor  gradient  steep  enough 
nor  any  temperature  inversion  strong  enough  to 
produce  superrefraction. 

From  this  it  may  be  seen  that  upper-air  soimd- 


ings  are  the  only  reliable  source  of  information 
as  to  where  and  when  tropospheric  DX  may  be 
worked.  The  isobars  (lines  of  common  atmos- 
pheric pressure)  shown  on  daily  weather  maps 
provide  good  clues,  but  they  are  not  infallible, 
as  any  experienced  and  observant  v.h.f.  man  will 
testify. 


The  Little  Shack 


A  Neat  Installation  for  the  Living  Room 

BY  LEN  H.  SMELTZER,*  W4KZF 


PROBABLY  many  XYLs  have  frowned  on  hav- 
ing the  ham  shack  in  the  living  room  because 
it  doesn't  look  much  like  normal  home  fur- 
nishings. We  wanted  to  put  a  small  transmitter 
and  receiver  in  the  Uving  room  so  we  wouldn't 
spend  all  our  time  ia  the  basement,  so  the  ques- 
tion of  a  suitable  enclosure  immediately  presented

Sufficient  space  (approximately  one  inch)  was  left 
on  top  and  on  each  side  of  the  transmitter  com- 
partment for  air  circulation,  and  the  backs  of 
both  compartments  were  left  open  for  the  same 
reason.  The  panel  under  the  transmitter,  near  the 
floor,  has  sufficient  room  on  the  rear  for  mounting 


itself.  When  the  16-ycar-old  junior  operator  came 
up  with  a  design  for  a  modern  cabinet  that  met 
with  the  approval  of  the  XYL,  he  and  yours 
truly  went  to  work  with  some  %-inch  plywood, 
glue,  and  nails.  The  result  is  shown  in  the  photo- 
graphs. 

This  cabinet  was  built  to  size  for  a  Viking 
Ranger  and  BC-342N  receiver,  with  additional 
space  in  the  receiver  compartment  for  the  control 
panel  and  Q-5er,  plus  storage  space  for  mike,  key,

Details  of  construction  will  not  be  given  here 
because  the  sizes  of  the  compartments  will  vary 
with  each  installation  to  accommodate  the  equip- 
ment in  use.  Also,  the  accessory  equipment  used 
with  the  receiver  will  help  to  determine  the  size 
of  that  compartment.  Our  purpose  here  is  just  to 
give  an  idea  of  what  can  be  done  with  a  little

maybe  you  have  a  friend  or  relative  who  likes  to

The  S-FS  Indicator 

A  Signal/ Field- Strength  Meter  for  Mobile  Use 

BY  C.  VERNON  CHAMBERS,  WIJEQ 


•  The  combination  is  a  natural  for  mo- 
bile work.  It  will  be  found  indispensable 
in  the  adjustment  and  servicing  of  re- 
ceiving, transmitting  and  antenna  sys- 
tems. It  is  also  most  useful  in  transmit- 
ter hunting  —  a  mobile  activity  that  is 
enjoying  widespread  popularity. 


SEPARATE  UNITS  foF  measuring  signal  and  field 
strength  were  described  by  W8IWB  and 
W0WLR  in  an  eariier  issue  of  QST}- «  Both 
of  these  used  a  1-ma.  meter  as  the  visual  indica- 
tor, and  a  500-ohm  potentiometer  for  adjustment. 
The  S-FS  Indicator  combines  the  original 
circuits  in  a  compact  package  permitting  a  single 
meter  and  potentiometer  to  do  double  duty.  The 
cost  of  the  dual-purpose  unit  is  very  little  more 
than  that  of  either  instrument  alone. 

The  unit  is  small  enough  for  mounting  either 
above  or  under  the  dashboard  of  a  car,  or  it 
may  be  stored  in  the  glove  compartment  when 
not  in  use.  It  is  housed  in  a  4  X  5  X  3-inch  gray 
hammertone  box  and,  complete  with  a  new 
meter,  costs  appro.ximately  $17.00  to  build. 

A  simple  toggle  switch  changes  from  one 
function  to  the  other.  Power  drawn  from  the 
broadcast  receiver  for  the  S-meter  circuit  is  less 
than  2}4  watts.  The  field-strength  circuit  re- 
quires no  external  power. 

The  field-strength  meter  can  be  used  installed 
in  the  car  as  an  antenna-resonance  indicator  or 
as  an  output  indicator  for  transmitter  adjust- 
ments, as  described  by  Abel,  or  it  can  easily  be 
removed  for  antenna-pattern  plotting,  adjust- 
ment of  other  mobile  installations  or  even  for 
use  in  the  home  station.  The  sensitivity  adjust- 
ment makes  the  indicator  useful  over  a  ■n-ide 
range  of  field  strengths. 

One  handy  feature  of  the  S-meter  arrangement 
is  the  sensitivity  control.  This  control  can  be 
adjusted  to  prevent  extremely  strong  signals 
from  pinning  the  meter,  ^^^len  working  with 
really  weak  signals,  the  sensitivity  control  may 
be  adjusted  to  provide  a  noticeable  meter 
deflection. 

Aside  from  ordinary  signal-strength  work, 
the  S-meter  may  be  used  to  advantage  when 
aligning  converter  or  receiver  circuits,  and  it  is 
worth  its  weight  in  gold  in  adjusting  antenna 
trap  circuits  to  suppress  QRM  from  b.c.  signal 
feed-through  in  converters.^  Mobileers  interested

Circuit 

The  circuit  of  the  S-FS  Indicator  is  shown 
in  Fig.  1.  A  12AX7  is  used  in  the  S-meter  section. 
One  grid  is  returned  directty  to  chassis  and  the 
second  grid  is  connected  to  the  sensitivity  con- 
trol, Ri.  The  input  end  of  Ri  is  returned,  via  J2 
and  a  shielded  cable,  to  the  a.v.c.  line  in  the

6-  and  12- volt  operation.  Pin  9  of  the  tube  is  not 
used  in  the  12- volt  circuit. 

For  S-meter  operation,  the  meter  and  R2  are 
switched  across  the  cathode  terminals  of  the 
tube  by  Si.  The  500-ohm  potentiometer,  R2, 
becomes  a  zero-adjust  control.  Zero  reading  is 
obtained  -nath  R2  adjusted  for  equal  voltage 
at  Pms  3  and  8  of  the  12AX7.  After  an  initial 
zero  adjustment,  the  application  of  a.v.c.  voltage 
through  Ri  will  drive  the  cathode  of  Fia  nega- 
tive with  respect  to  the  cathode  of  F2B,  thus 
upsetting  the  meter  balance  and  causing  an 
upward  deflection.  For  a  given  a.v.c.  voltage.

the  amplitude  of  the  deflection  will  l)e  controlled 
by  Ri. 

The  S-FS  Indicator  uses  a  Type  12AX7  in 
preference  to  the  6SN7  employed  by  W0WLR 
because  it  draws  considerably  less  plate  current. 
This  saving  is  important  if  power  for  the  S-meter, 
as  well  as  the  converter,  is  taken  from  the  b.c. 
receiver.  The  6SN7  and  its  prototype  (12BH7) 
will  work  well  in  the  circuit,  but  only  at  the 
expense  of  increased  current  drain. 

The  circuit  of  the  field-strength  section  is 
electrically  equivalent  to  the  one  described 
previously.^  It  is  made  active  by  switching  the 
meter  and  R2  into  the  circuit  and  by  applying 
r.f.  through  Ji.  The  amount  of  r.f.  fed  to  the  cir- 
cuit may  be  controlled  bj^  adjusting  the  length 
of  the  pick-up  antenna  attached  to  Ji.  R2  is  a 
shunt  to  prevent  off-scale  readings  when  measur- 
ing strong  r.f.  fields. 

Con  struc  Hon 

As  shown  in  the  top  view,  the  Triplett  model 
227-T  meter  is  mounted  on  the  front  panel  of 
the  utility  box.  If  the  meter  is  centered  with  its 
top  edge  1^  inches  down  from  the  top  of  the 
panel,  the  barrel  of  the  meter  will  not  strike  the 
folded-over  lips  at  the  front  of  the  box  when  the 
unit  is  assembled.  <Si  and  R2  are  below  the  meter 
with  a  1 3^-inch  space  between  mounting  centers. 
Each  control  is  centered  1^^  inches  up  from  the 
bottom  of  the  panel. 

The  rear  and  the  bottom  views  show^  the 
"U"-shaped  chassis  made  from  1/16-inch  thick 
aluminum  stock.  The  width,  depth  and  height 
of  the  chassis  are  2J/8,  3  and  1  11/16  inches, 
respectively.  Panel-mounted  controls  {Ri  and 
.Si)  clamp  the  chassis  against  the  rear  of  the 
front  panel  as  showTi   in   the  bottom  view.    A

mounted  meter.  The  tuning  slug  for 
L\,  the  sensitivity  control  and  the 
power  and  antenna  jacks  are  also 
visible. 


]  2-inch  space  is  left  between  the  bottom  edge 
of  the  chassis  and  the  bottom  of  the  panel  to 
provide  clearance  for  the  lower  front  lip  of  the 
cabinet. 

The  socket  for  the  12AX7  is  centered  1  inch 
in  from  the  rear  edge  of  the  chassis.  L\  is  located 
just  to  the  right  of  the  tube  socket  as  seen  in  the 
rear  view.  Li  is  a  North  Hills  type  120-H  inductor 
having  an  inductance  range  of  105  to  200  Aih. 
However,  any  coil  that  will  resonate  around 
3.9  Mc.  (and  still  fit  into  the  chassis)  with  the 
circuit  capacitance  may  be  used.  A  hole  in  the 
front  of  the  socket,  fitted  with  a  rubber  grommet, 
passes  the  leads  between  the  meter  and  the 
toggle  switch.  Ri,  Ji  and  J2  are  mounted  on  the 
rear  wall  of  the  chassis. 

The  bottom  view  shows  the  r.f.  choke  and  the 
disk  capacitors  for  the  field-strength  circuit 
mounted  on  a  2-terminal  tie-point  strip  at  the 
right  side  of  the  unit.  The  extra  terminals  on  the

slug-tuned  coil  are  used  for  mounting  the  1N34 
crystal  diode.  Ordinarj'  hook-up  wire  is  used 
throughout. 

Installation 

Heater,  plate  and  a.v.c.  voltages  for  the  S- 
meter  are  obtained  from  the  car  b.c.  receiver 
and  should  be  brought  to  the  indicator  through 
shielded  leads.  A  suitable  cable  can  be  made  from 
lengths  of  Belden  No.  8885  shielded  wire.  The 
heater  lead  may  be  tapped  onto  the  hot  side  of 
any  receiver  tube  (it  is  a  good  idea  to  stay  clear 
of  the  rectifier  tube)  close  to  a  hole  or  receptacle 
provided  for  the  output  cable.  The  plate  lead 
may  be  connected  to  the  screen  pin  of  an  audio 
output  tube  socket,  to  a  low-voltage  tap  on  the 
power  supply  or  to  any  other  point  delivering 
approximately  150  volts  (higher  voltages  merely 
increase  the  current  drain  unnecessarily).  A  series 
resistor  may  also  be  used  to  drop  the  voltage. 
It  should  have  a  value  of  approximately  285 
ohms  for  each  volt  in  excess  of  150. 

Finding  the  a.v.c.  line  in  a  car  b.c.  receiver  is 
not  always  an  easy  job  unless  you  are  lucky 
enough  to  have  a  circuit  diagram  and  a  layout 
plan.  It  is  frequently  possible  to  spot  the  line  by 
tracing  back  from  the  control  grid  of  either  the 
r.f.  amplifier  tube  or  the  converter.  The  grid  of 
each  tube  is  usually  returned  to  the  a.v.c.  bus 
through  a  '^  o-  to  1 -megohm  resistor.  If  you  test  a 
junction  for  a.v.c.  voltage,  just  connect  a  high- 
resistance  d.c.  voltmeter  betwotMi  the  point  and 
ground  and  watch  for  a  negative  reading  that 
increases  with  increased  signal  input.  Local  b.c. 
stations  can  supply  the  test  signals. 

After  the  interunit  cabling  luis  been  completed, 
the  receiver  may  be  returned  to  the  dash  of  the 
car.  The  performance  of  the  S-meter  may  now  be 
checked  bj-  tuning  in  signals  —  either  amateur 
or  b.c.  —  and  observing  the  deflection  of  the 
meter.  If  b.c.  station  signals  cause  only  a  small 


deflection,  it  indicates  that  Ri  is  adjusted  toward 
minimum  sensitivity.  In  that  case,  readjust  Ri, 
zero  the  meter 'by  means  of  Ro,  and  try  again. 
It  is  necessary  to  reset  the  zero-adjust  control 
each  time  that  the  sensitivity  control  setting  is 
altered.  Of  course,  if  signals  tend  to  pin  the 
meter,  the  sensitivity  can  be  reduced  by  adjust- 
ment of  Ri. 

With  150  volts  applied  to  the  plates  of  the 
12AX7,  with  the  grid  of  I^ia  grounded  (,Ri  at 
minimum  sensitivity  position),  and  with  the 
meter  adjusted  to  zero,  the  tube  should  draw 
about  3.5  ma.  The  voltage  at  the  two  cathode 
terminals.  Pins  3  and  8,  should  be  0.4  volts. 

The  field-strength  meter  can  be  most  quickly 
tested  by  using  the  mobile  transmitter  as  the 
source  of  signal.  Either  a  short  length  of  wire, 
the  b.c.  antenna,  or  an  insulated  fender  guide'- 
may  be  used  as  the  r.f.  pick-up.  Just  terminate 
the  pick-up  antenna  at  Ji,  throw  <Si  to  the  proper 
position,  adjust  Ro  for  maximum  resistance 
across  the  milliammeter,  turn  on  the  transmitter 
and  watch  the  needle.  Lengthen  the  pick-up 
antenna  if  the  meter  deflection  is  not  great 
enough,  or  regulate  the  shunt,  Ro,  if  the  reading 
is  too  high.  It  is  just  as  well  to  shorten  the  pick-up 
antenna  a  bit  if  the  shunt  resistance  has  to  be 
lowered  appreciably.  Try  and  end  up  with  an 
antenna  length  that  serves  the  purpose  as  far 
as  j'our  own  installation  is  concerned  and  also 
provides  enough  pick-up  to  permit  making 
measurements  of  a  more  sensitive  nature.  The 
latter  would  include  measuring  the  field  strength 
from  the  mobile  transmitter  of  a  fellow  ham  who 
is  parked  alongside  of  your  vehicle. 

Li  should  ordinarily  require  adjustment  only 
if  the  indicator  is  used  for  checking  at  75  meters. 
In  that  case,  it  is  advisable  to  increase  the 
sensitivity  to  maximum  by  resonating  the  coil. 
Abel  has  explained  \vh.\-  a  tuned  circuit  is  not 
required  at  the  higher  fretiuencies. 


The  function  switch  is  to 
the  left  of  the  zero-adjust 
control  in  this  bottom  view  of

the  components  mounted  on

A  Low-Cost  Code-Practice  Oscillator 

A.C.  Power  with  Safety  Features 

BY  ROBERT  E.  FOLTZ,*  W9GBT 


IN  looking  for  a  good  design  for  a  code-practice 
oscillator,  certain  requirements  were  estab- 
lished: The  unit  must  be  powered  from  the 
a.c.  line  yet  provide  complete  isolation  for  safety; 
there  should  be  no  shock  hazard  in  the  keying 
circuit ;  and  in  addition,  speaker  operation  was  de- 
sired without  added  cost  or  circuit  complication. 

Units  have  been  described  using  a  filament 
transformer  for  the  tube  heaters,  with  the  plate 
voltage  obtained  from  batteries  or  a  rectifier 
supply.  A  study  of  transformers  available  dis- 
closed a  type  used  in  TV  boosters  having  a  plate 
winding  of  110  to  150  volts  at  15  to  25  ma.,  in 
addition  to  a  filament  winding,  at  a  cost  of  only 
fifteen  cents  more  than  a  single  filament  trans- 
former. 

A  selenium  rectifier  was  first  considered  for  ob-

•  Using  a  TV  horizontal-oscillator  coil  in 
the  oscillator  circuit  makes  it  possible 
to  drive  a  speaker  voice  coil  without  a 
matching  transformer.  Combined  with  a 
"booster"  transformer,  the  result  is  an 
inexpensive  self-contained  code-practice 
oscillator. 


taining  the  necessarj'  d.c.  plate  voltage,  but  fur- 
ther stud}^  indicated  that  a  dual-triode  tube 
would  be  more  economical  in  both  cost  and  space, 
by  using  one  section  as  a  half-wave  rectifier  and 
the  other  as  the  audio  oscillator. 

The  ordinary  audio-oscillator  circuit  calls  for 
an  audio  interstage  transformer,  which  accounts 
for  a  good  portion  of  the  total  parts  cost.  In  this 
design,  a  horizontal-oscillator  coU,  as  employed 
in  TV  receivers,  is  used  in  the  feed-back  circuit. 
In  addition  to  economj^,  the  adjustable  ferrite 
core  provides  the  means  for  adjustment  of  tone 
without  the  added  cost  of  the  usual  potentiometer. 

The  number  of  components  in  the  circuit  of 
Fig.  1  is  small,  as  all  frills  were  eliminated  in  the 
interests  of  simplicity  and  low  cost.  New  parts  as 
checked  in  a  catalog  total  under  $6.00,  not  includ- 
ing the  speaker  or  cabinet.  Many  of  the  parts  can 
be  found  in  special  sale  catalogs  or  at  bargain 
counters  at  most  of  the  larger  supplj-  houses.  The 
parts  for  this  particular  unit,  bargain-purchased, 
amounted  to  only  $4.03.  An  additional  $1.05  pro- 
vided a  2-inch  speaker. 

The  Circuit 

Referring  to  the  circuit,  it  will  be  noted  one 
triode  section  of  the  12AU7  functions  with  grid 
and  plate  tied  together  as  a  half-wave  rectifier.

A  28-Mc.  Civil  Defense  Package 

Three-Channel  Fixed- Portable-Mobile  Station  for  Emergency  Use 
BY  PHILIP  S.  RAND.*  WIDBM 


•  The  three  basic  units  —  transmitter, 
receiver,  power  supply  —  of  an  emer- 
gency station  have  to  be  coordinated 
electrically  as  a  matter  of  practical 
operation.  Here's  a  "package"  that  car- 
ries the  coordination  still  further,  put- 
ting three  identical-size  units  into  a 
compact  station  that  can  be  picked  up 
and  carried  anywhere  in  one  piece,  yet 
which  can  readily  be  separated  into  com- 
ponents for  separate  use  or  servicing. 
Utility  and  appearance  are  combined 
without  excessive  cost. 


THE  EQUIPMENT  to  be  described  is  the  result 
of  the  efforts  of  three  amateurs  who  joined 
together  to  solve  a  civil  defense  communica- 
tions problem  in  a  small  Connecticut  town.  This 
same  problem  probably  exists  in  hundreds  of 
other  small  communities  all  over  the  country. 

Redding,  a  rural  community  with  a  population 
of  only  about  2500,  is  situated  in  the  hills  of 
Connecticut  about  sixty  miles  northeast  of  New 
York  City  and  about  twenty  miles  northwest  of 
Bridgeport,  Connecticut.  The  people  live  in  a 
number  of  small  villages  scattered  throughout 
the  town  limits.  Redding  is  one  of  the  twenty- 
two  towns  and  cities  which  constitute  "Area 
One"  of  the  State  of  Connecticut  Civil  Defense 
system.  Area  One  is  one  of  the  most  active  civil 
defense  areas  of  Connecticut.  Unfortunately  for 
Redding  there  are  only  three  amateurs  in  the 
town,  two  of  whom  are  already  up  to  their  ears 
in  c.d.  work  at  Area  Headquarters. 

One  of  the  problems  was  how  to  organize  an 

*  Redding  Ridge,  Conn. 


efficient  RACES  program  with  only  one  ham 
available  locally.  Another  problem  was  that  of 
obtaining  appropriate  station  equipment  without 
any  funds,  because  it  was  found  that  although 
Redding  had  the  nucleus  of  a  c.d.  organization  it 
waa  not  active  and  there  was  no  money  for  radio 
gear.  The  third  problem  was  how  to  make  the 
c.d.  organization  in  Redding  more  active  so  it 
would  take  part  in  the  weekly  training  exercises. 
It  was  sort  of  Hke  the  old  question  of  which  came 
first,  the  chicken  or  the  egg:  No  c.d.  activity,  no 
communications;  no  communications  wnth  the 
rest  of  the  area,  no  activity  locally.  Past  experi- 
ence with  other  towns  in  Area  One  had  shown 
conclusively  that  if  radio  communications  could 
be  set  up  and  maintained  between  an  inactive 
town  and  Area  Headquarters,  interest  in  all 
branches  of  the  local  c.d.  set-up  was  stimulated 
enough  to  spark  the  whole  operation  into  life. 
WIDBM,  WIKGT  and  WlODW  held  a  meet- 
ing, procured  an  egg,  and  hatched  out  the  fol- 
lowing: 

1)  They  formed  a  bona  fide  radio  club  with 
themselves  and  their  XYLs  as  members  and  ap- 
plied to  FCC  for  a  club  radio  station  license.  This 
station  was  to  be  the  local  c.d.  station  for  contact 
with  Area  Headquarters  and  was  to  be  located 
at  c.d.  headquarters  in  the  Town  Hall.  FCC  is- 
sued a  station  license,  WlDUL. 

2)  Through  notices  in  the  newspapers,  at  the 
school  and  by  word  of  mouth,  they  w-ere  able  to 
get  about  ten  new  members  for  the  radio  club. 
All  of  the  non-amateur  members  are  obtaining 
Restricted  Radiotelephone  Permits  from  FCC, 
are  being  trained  in  RACES  operating  proce- 
dure, and  will  be  used  as  operators. 

3)  WlODW  was  appointed  Redding  Radio 
Officer  by  the  local  c.d.  director,  and  he  imme- 


(Lefi):  The  three  units  assembled  in  their  carrier.  Transmitter,  receiver,  and  power  supply  are  included  in  the 
"package."  The  outfit  can  run  either  on  regular  a.c.  or  on  a  6-volt  battery  supply.  The  carrier  is  made  from  a  cut- 
down  3^-inch  aluminum  relay  rack  panel  as  a  base,  with  aluminum  uprights  and  crosspiece  supporting  the  handle. 
Individual  units  are  fastened  to  the  base  with  screws.  {Right):  Rear  view  of  the  assembled  station  shows  the  con- 
verter mounted  in  place  on  the  back  of  the  receiver. 


diately  made  out  the  necessary  RACES  applica- 
tion forms  tying  Redding  into  the  Area  and 
State  RACES  plan.  These  forms  were  forwarded 
to  the  State  Radio  Officer. 

4)  Redding  had  previously  been  assigned  to 
the  Area  ten-meter  net.  WlDBM,  WlKGT  and 
WlODW  pooled  ideas  and  parts  and  divided  up 
the  actual  work  in  designing,  constructing  and 
installing  a  complete  ten-meter  c.d.  station  for 
the  town.  The  station  will,  of  course,  be  owned 
and  operated  by  the  Redding  Radio  Club,  with 
one  of  the  amateur  members  as  Trustee. 

When  planning  a  RACES  station  like  this,  it 
must  be  kept  in  mind  that  it  will  take  more  than 
just  one  radio  operator  to  man  it.  A  typical  c.d. 
set-up  would  require: 


a)  one  Communications  Officer  with  three  as- 
sistanta  or  alternates  (in  charge  of  all  types  of 
communications) ; 

b)  one  Radio  Officer  with  three  alternates  (in 
charge  of  all  radio  communications); 

c)  three  dispatchers; 

d)  one  chief  operator  in  charge  of  all  operators; 

e)  one  technician  in  charge  of  all  equipment; 

f)  four  radio  operators  for  each  transmitter 
in  use; 

g)  at  least  four  messengers  for  delivering 
messages. 

This  makes  a  total  of  twenty-four  people  for  a 
one-transmitter  station,  a  rather  imposing  list; 
however,  all  RACES  stations  should  be  organ-

the  time  ever  comes  when  c.d.  communications 
are  vitally  needed,  half  of  your  personnel  may  be 
knocked  "out  or  otherwise  unavailable,  so  you 
need  plenty  to  start  with.  (Incidentally,  all  ama- 
teur stations  not  in  RACES  will  be  definitely  off 
the  air  in  the  event  of  a  national  emergency  re- 
sulting from  enemy  action.) 

Fortunatelv  for  small  towns  wnth  only  a  few 
hams,  only  the  Radio  Officer,  his  alternates  and 
the  technician  need  be  hcensed  amateurs.  The 
rest  need  only  hold  Restricted  Radiotelephone 
Permits.  RACES  mobiles  can  be  owned  and  op- 
erated by  Restricted  Permit  holders,  if  need  he. 

Transmitter 

In  the  actual  design  of  the  equipment,  it  was 
first  determined  by  a  mobile  test  that  a  15-watt 
transmitter  with  a  10-meter  ground-plane  an- 
tenna would  be  adequate  to  span  the  twelve  air- 
line miles  from  the  Redding  Town  Hall  to  Area 
One  Control.  With  this  as  a  basis,  it  was  possible 
to  build  a  rig  with  a  combination  120-volt  a.c./6- 
volt  d.c.  power  supply  so  that  the  transmitter 
could  be  independent  of  power  failures.  By  the 
addition  of  a  carrying  handle,  it  could  also  be  used 
as  a  portable  or  a  mobile  if  need  be. 

Going  on  from  this  point,  a  simple  yet  effective 
r.f.  unit  was  built  and  tested  using  a  6AU6  crystal 
oscillator  followed  by  a  6AQ5  doubler  and  a  2E26

final    amplifier.    The    circuit 
is  shown  in  Fig.  1,  along  mth 
the  12AU7  Class  B  modula- 
tor.  There  are  three  crystal 
frequencies  available,  one  for 
the  Area  channel,  one  for  the 
local  channel  and  one  for  the 
statewide  mobile  support  fre- 
quency.   In   the   interests   of 
good    audio    c[uaUty    (which 
cuts  dowii  on  repeats  and  fills 
in  handling  messages),  a  crys- 
tal microphone  was  selected 
and  the  necessary  audio  am- 
plification was  built  in.  The 
12AU7    Class    B    modulator 
was  chosen  because  of  its  low 
static  plate  current.  The  use 
of   a  cathode   follower  for  a 
driver    eliminated    the    need 
for  a  Class  B  driver  trans- 
former. 

For  simplicity  in  tuning 
and  antenna  loading,  a  pi 
network  was  used  in  the  final 
plate  circuit.  The  plate  tun- 
ing and  antenna  loading  con- 
trols are  the  only  ones  brought 
out  to  the  front  panel.  The 
crystal-oscillator  plate  and 
doubler  plate  are  tuned  with 
a  screwdriver  through  suit- 
able holes  in  the  top  of  the 
cabinet. 
In  addition  to  the  crystal  switch  and  the  audio 
gain  control,  there  is  a  s.p.d.t.  toggle  switch  on 
the  front  panel  for  turning  on  the  crystal  oscil- 
lator alone  so  that  the  transmitter  can  be  spotted 
on  the  receiver.  This  is  a  big  help  to  inexperienced 
operators  in  locating  the  net  frequency. 

A  small  d.p.d.t.  120-volt  a.c.  relay  shifts  both 
the  antenna  and  B-plus  from  the  receiver  to  the 
transmitter  when  the  send-receive  switch  is 
thro\\-n.  This  relay  is  connected  to  the  120-volt 
winding  on  the  transformer  so  that  it  works  re- 
gardless of  whether  a.c.  or  battery  is  being 
used  for  primary  power. 

Receiver 

Many  ideas  on  receivers  were  discussed  and 
rejected,  including  using  a  BC-348,  a  312,  or  an 
ARC-5  with  a  tunable  converter,  or  rebuilding  a 
junked  ham  receiver.  The  amount  of  work  involved 
in  designing  and  building  a  complete  10-meter 
receiver  with  a  good  noise  Umiter,  adequate  stabil- 
ity, sensitivity,  bandspread,  and  so  on,  was  a  Uttle 
frightening.  A  good  solution  finally  came  when 
some  144-Mc.  technique  was  borrowed,  resulting 
in  a  simple  crystal-controlled  converter  ahead  of 
a  homemade  broadcast  receiver.  Fig.  2  shows 
the  circuit  of  the  converter,  which  uses  a  7-Mc. 
crvstal  and  a  pair  of  6AG5s.  Fig.  3  gives  the  cir- 
cuit of  the  tunable  i.f.  amplifier  (540  kc.  to  1750 
kc).  This  has  the  useful  feature  that  the  home- 
made dial  can  be  calibrated  in  both  10-meter  fre- 
quencies and  b.c.-band  frequencies,  and  if  the

need  arises  the  converter  can  be  unplugged  and 
the  Conebad  channels,  640  kc.  and  1240  kc,  can 
be  received.  These  are  both  marked  on  the  paper 
dial.  Also,  other  crj^stal  converters,  such  as  for 
144  or  50  Mc,  can  be  plugged  in  either  for  regular 
use  or  for  monitoring  purposes.  The  tuning  range 
is  about  1210  kc,  or  from  approximately  28.5 
to  29.7  Mc.  This  same  range  would  apply  on 
either  6  or  2  meters,  so  an  appropriate  crystal 
would  have  to  be  used  in  these  converters  to 
cover  the  desired  1.2-Mc.  portion  of  the  band. 

The  untuned  r.f.  stage  used  in  the  broadcast 
tuner  was  found  necessary  to  prevent  birdies 
resulting  from  the  two  oscillators  beating  to- 
gether in  the  mixer  grid  circuit.  It  is  recommended 
that  anyone  building  a  similar  receiver  use  a 
tuned  stage  of  r.f.  with  a  three-gang  capacitor  in- 
stead of  the  two-gang  unit  we  used,  ^^^len  we 
discovered  the  birdies  it  was  too  late  to  install  the 
three-gang  condenser,  so  we  did  the  next  best 
thing  and  isolated  the  two  oscillators  with  the  un- 
tuned stage. 

A  6U8  was  used  as  an  oscillator-mixer  because 
one  was  available.  A  6BE6,  or  another  type  of 
converter,  could  have  been  used  just  as  well.

Two  stages  of  455-kc.  i.f.  were  used  to  provide 
enough  gain  so  that  the  i.f.  transformers  could  be 
stagger  tuned  for  a  broader  passband,  making 
tuning  easier  for  inexperienced  operators. 

The  second  detector,  a  6AL5,  also  provides 
a.v.c.  and  noise  limiting.  The  audio  is  conven- 
tional, except  that  a  s.p.d.t.  toggle  switch  allows 
switching  from  'phones  to  loudspeaker  when 
needed.  Normally  all  reception  is  with  'phones 
in  c.d.  work. 

Povrer  Supply 

A  schematic  of  the  power  supply  is  shown  in 
Fig.  4.  A  combination  a.c. /vibrator  transformer 
is  used  so  that  primary  power  can  be  either  reg- 
ular a.c.  or  6  volts  d.c.  By  using  12-contact  power 
plugs,  the  selection  between  a.c.  and  d.c.  is  made 
simply  by  plugging  in  the  proper  plug.  ^Iien  the 
d.c.  cable  is  plugged  in  the  vibrator  is  automati- 
cally connected  in  the  circuit. 

The  circuit  is  straightforward,  except  perhaps 
for  the  use  of  selenium  rectifiers.  These  were  used 
in  order  to  save  2  amp.  that  would  have  been 
needed  for  heating  the  rectifier  filaments  if  tube 
rectifiers  had  been  used.  Four  200-ma.  selenium

units  were  used  in  each  stack  because  they  were 
available;  three  75-ma.  units  could  have  been  used 
just  as  well. 

The  fixed  bias,  —22  volts,  for  the  r.f.  and  mod- 
ulator is  obtained  from  the  drop  across  a  200- 
ohm  25-watt  adjustable  resistor  in  the  trans- 
former center  tap.  This  robs  22  volts  from  the 
high  voltage;  however,  the  drop  in  plate  voltage 
is  not  missed,  and  the  sjstem  is  better  than  re- 
placing "C"  batteries. 

Construction 

As  can  be  seen  from  the  photographs,  the  en- 
tire station  is  made  up  of  three  small  units.  This 
was  done  for  ease  of  construction  and  servicing. 
In  use,  these  units  are  all  bolted  to  a  common 
bottom  or  base  plate  which  is  equipped  with  a 
carrying  handle.  In  the  front-view  photograph 
the  transmitter  unit  is  on  the  left,  the  receiver  is 
in  the  center,  and  the  power  supply  is  on  the 
right.  The  crystal-controlled  28-Mc.  converter  is 
attached  to  the  rear  of  the  main  receiver  and  the 
low-pass  filter  is  tucked  in  back  of  the  transmitter. 

In  actual  use  in  the  Town  Hall,  the  complete 
set-up  is  housed  in  a  plywood  cabinet  with  a 
hinged  door  that  can  be  either  locked  when  not 
in  use  or  can  be  dropped  down  for  use  as  an  op- 
erating table.  There  are  shelves  and  compartments 
for  the  microphone,  headsets,  logbook,  message 
pads,  and  similar  accessories. 

The  crystal  converter  is  built  in  a  3  X  4  X  5- 


inch  utihty  box  with  the  components  mounted 
on  one  of  the  covers.  This  box  is  attached  with 
small  aluminum  brackets  to  the  top  rear  of  the 
main  receiver. 

The  transmitter,  receiver  and  power  supply 
are  each  constructed  on  a  standard  3  X  5  X  10- 
inch  aluminum  chassis  equipped  with  homemade 
front  and  rear  panels  8  inches  high.  The  panels 
have  J^-inch  hps  folded  over  so  that  the  per- 
forated aluminum  sheet  (Rej'nolds  "  do-it-j'our- 
self"  material  now  available  in  most  hardware 
stores)  for  the  shielding  can  be  secured  ^vith 
sheet  metal  screws.  In  our  case  we  completed  all 
three  cabinets  (all  holes  drilled  and  punched) 
and  then,  after  assembling  them,  sprayed  them 
with  grey  wrinkle  enamel.  Baking  under  some  in- 
frared heat  lamps  finished  the  paint  job.  Next, 
Tekni-Label  decals  were  appUed  and  the  result 
was  a  professional-looking  job. 

On  the  transmitter  chassis  the  speech  amplifier 
tubes  are  across  the  rear,  separated  bj^  the  mod- 
ulation transformer  from  the  r.f.  The  cr>'stal 
oscillator  is  in  the  center  of  the  chassis  and  the 
final  amplifier  is  toward  th^^  front  panel.  The  an- 
tenna relay  is  j  .st  behind  the  antenna  loading 
condenser. 

The  two  coax  cables  from  the  connectors  on  the 
rear  panel  run  to  a  bracket  just  behind  the  relay. 
One  of  these  goes  to  the  antenna  and  one  to  the 
converter.

meter  and  the  meter  switch  are  both  locat-ed  in 
the  power  supply  and  a  12-wire  cable  intercon- 
nects these  two  units.  The  meter  shunts,  how- 
ever, are  in  the  transmitter.  These  must  be  tail- 
ored to  fit  the  particular  meter. 

The  vibrator  and  the  filter  condenser  can  are 
mounted  along  the  rear  edge  of  the  power  suppl>' 
chassis.  The  power  transformer  occupies  most  of 
the  space  in  the  middle.  The  selenium  rectifiers 
are  mounted  on  two  5-inch  6-32  threaded  rods 
lietween  two  aluminum  end  brackets,  toward  the 
front  just  behind  the  2-inch  milliammeter.  The 
filter  choke  is  mounted  under  the  chassis  in  the 
center  while  the  r.f.  choke  for  the  battery  lead 
is  just  to  the  rear. 

Note  that  all  terminals  of  the  output  cable 
sockets  are  by-passed  with  0.001  disk  ceramic 
capacitors.  In  the  transmitter  unit  this  keeps  TV 
harmonics  from  escaping,  while  in  the  power 
supply  it  keeps  vibrator  hash  in  its  place.  In  the 
receiver  it  helps  to  keep  the  two  oscillators  from 
beating  together.  This  by-passing  also  helps  to 
keep  broadcast  signals  from  entering  the  receiver 
via  the  power  leads.  These  precautions  may  not 
be  needed  in  every  installation,  but  since  it  was 
easier  to  put  the  bj'-passes  on  before  installing 
the  sockets  we  put  them  on  "just  in  case."  All 
0.001  and  0.01  capacitors  are  of  the  disk  ceramic 
tj'pe,  including  the  audio  coupling  units.  This 
makes  for  a  very  neat  and  compact  wiring  job. 

In  lajdng  out  the  receiver  chassis,  the  tuning 
capacitor  had  to  be  mounted  slightly  off  center 
to  allow  room  for  the  shield  cans  of  the  r.f.,  mixer 
and  oscillator  coils  which  line  up  on  the  left.  The 
i.f.  transformers  and  tubes  are  along  the  right 
side,  with  the  two  audio  tubes  on  the  rear  edge. 
Miscellaneous  components  are  grouped  on  termi- 
nal boards  on  either  side  under  the  chassis.  The 
volume  control  is  mounted  on  a  small  bracket 
toward  the  rear  so  as  to  be  near  the  first  audio 
stage.  The  audio  output  transformer  is  mounted 
near  the  output  tube,  with  shielded  leads  running 
to  the  'phones-speaker  switch  up  front  and  thence 
back  to  the  two  jacks. 

The  dial  was  made  by  cutting  and  filing  an 


aluminum  frame  to  mount  over  white  cardboard 
on  which  the  frequencies  were  lettered  in  India 
ink.  The  knob  itself  is  one  from  the  junk  box  with 
a  celluloid  pointer  attached.  A  vernier  action  dial 
woukl  be  more  suitable,  if  available. 

The  i.f.  output  coil  of  the  converter  is  a  broad- 
cast-band untuned  antenna  coil  hooked  up  in 
reverse.  If  the  builder  should  use  this  same  coil,  it 
will  be  necessarj'  to  separate  the  two  windings,  the 
ground  ends  of  which  are  both  soldered  to  the 
same  lug  on  the  coil  form,  and  connect  the  an- 
tenna-winding lead  to  the  spare  lug.  This  pre- 
vents B-plus  from  appearing  on  the  output  wind- 
ing. It  was  found  that  this  particular  coil  reso- 
nated near  600  kc,  so  about  half  the  turns  were 
removed  from  the  "grid"  winding  and  the  out- 
put was  much  more  uniform  across  the  10-meter 
band.  These  same  modifications  were  made  to 
the  untuned  r.f.  stage  in  the  receiver  proper,  to 
make  the  coil  tune  better  and  to  avoid  shorting 
out  the  a.v.c.  Before  removing  turns  it  is  well  to 
check  the  receiver  response  to  see  if  such  modi- 
fication will  be  necessary. 

The  interconnecting  power  and  coax  cables  all 
connect  to  the  rear  of  the  chassis  and  are  about 
24  inches  long  so  that  the  various  units  may  be 
readily  separated  and  turned  upside  down  for 
testing  and  servicing. 

Testing 

After  all  four  units  are  assembled  and  wired, 
the  power  supply  should  be  tested  first.  Check 
the  circuit  over  before  turning  on  the  power,  to  be 
sure  there  are  no  mistakes  or  shorts.  Remember 
that  the  negative  side  of  the  filter  capacitors  goes 
to  the  -22  volts,  not  to  ground;  there  will  be  a 
bad  a.c.  hum  in  the  audio  if  the  capacitors  are 
grounded.  With  no  load  the  B-plus  voltage  will 
run  around  400  or  higher,  but  with  full  load  on 
transmitting  it  is  down  to  about  300  volts. 

The  voltage  during  receiving  runs  about  350 
volts  but  is  reduced  in  the  receiver  by  the  rather 
high  values  of  decoupling  resistors  used  in  addi- 
tion to  a  series  resistor  in  the  transmitter  unit. 

Alignment  of  the  receiver  follows  usual  prac-

The  perforation  pattern 
on  the  bent-over  edges  of 
the  front  and  rear  panels 
results  from  spray-paint- 
ing the  cases  with  the  cov- 
ers in  place.  This  avoids 
necessity  for  subsequent 
scraping  of  paint  to  make 
good  electrical  contact 
with  the  perforated  shields.

tice.  Feed  a  signal  from  a  signal  generator  at  455 
kc.  into  the  last  i.f.  grid  and  align  Tt  first,  then 
work  toward  the  mixer  one  stage  at  a  time, 
reducing  the  output  of  the  signal  generator  each 
time  so  that  nothing  overloads.  A  vacuum-tube 
voltmeter  plugged  into  the  a.v.c.  test  jack  makes 
both  a  good  S-meter  and  an  alignment  indicator. 
The  i.f.  should  be  stagger-tuned  according  to  the 
frequencies  given  in  the  caption  for  Fig.  3. 

After  ahgning  the  i.f.,  proceed  wth  the  r.f. 
and  mixer  stages.  When  the  receiver  proper  is 
lined  up  so  that  it  works  well  on  the  broadcast 
band,  the  converter  may  be  tested.  Check  the 
two  r.f.  coils  with  a  grid-dip  meter  after  {hey  are 
wired,  but  with  the  tube  filaments  turned  off.  The 
crystal-oscillator  plate  coil  should  dip  at  around 
28  Mc.  while  the  mixer  coil  should  show  resonance 
at  about  29  Mc. 


The  receiver  section  has 
too  much  gain  with  the  i.f. 
transformers  tuned  on  the 
nose  and  the  full  power  sup- 
ply voltage  applied,  so  some 
trouble  from  oscillation  may 
result  if  one  attempts  to 
operate  it  in  that  fashion. 
As  pointed  out  earlier,  large 
decoupling  resistors  were  in- 
tentionally used  to  drop  the 
plate  voltage,  and  the  i.f. 
transformers  were  stagger- 
tuned  to  increase  the  i.f. 
bandpass  for  easier  tuning. 
The  two  oscillators,  one 
in  the  converter  and  one  in 
the  receiver,  should  both  be 
operated  at  as  low  a  value 
of  plate  voltage  as  is  con- 
sistent with  good  mixing. 
This  keeps  the  amplitude  of 
any  beats  or  birdies  as  low 
as  possible,  birdies  always 
being  a  problem  in  double- 
(!onversion  receivers.  A  final 
check  should  be  made,  after 
the  unit  is  operating,  to 
make  sure  that  the  voltages  at  each  tube  socket 
are  near  those  given  in  Table  I.  If  they  differ  ap- 
preciably, the  appropriate  resistors  should  be 
changed  accordingly. 

The  transmitter  coils  should  be  checked  with 
a  grid-dij)  meter  to  be  sure  they  tune  to  the  right 
frequencies  —  the  oscillator  coil  to  14.5  Mc,  and 
the  doubler  and  final  coils  to  29  Mc.  —  with  their 
condensers  about  one-half  capacitance.  If  the 
transmitter  is  tuned  up  on  29.5  Mc,  7-Mc. 
crystals  giving  output  frequencies  from  29.4  to 
29.6  may  be  switched  in  without  any  retuning. 
If  you  plan  to  use  widely  separated  frequencies 
it  will  be  necessary  to  retune  all  stages  when 
switching  crj^stals. 

No  trouble  was  experienced  in  getting  the 
transmitter  on  the  air.   However,   there  was  a

A  500- Watt  144-Mc.  Amplifier 

High  Efficiency  at  Moderate  Cost  with  War-Surplus  Triodes 

BY  LEONARD  F.  GARRETT,*  W7JIP 


THE  idea  of  running  high  power  is  attractive 
to  many  2-meter  men,  but  the  cost  of  the 
tubes  and  other  components  often  proves  to 
be  a  stumbhng  block.  The  amplifier  described 
here  doesn't  quite  make  the  kilowatt  level,  but  it 
will  handle  500  watts  with  ease,  and  with  good 
efficiency.  It  is  built  around  surplus  HK-54s  that 
were  purchased  for  two  dollars  each,  so  the  total 
cost  is  far  below  that  for  a  tetrode  amplifier  of 
similar  power  level  using  new  tubes. 

Much  of  the  "low-drive  "  advantage  of  tetrodes 
fades  when  they  are  used  at  frequencies  near  the 
maximum  at  which  they  are  capable  of  operating 
with  reasonable  efficiency.  A  9903  or  an  829-B 


*3003  S.E.  71st  Ave.,  Portland,  Ore. 


is  customarily  used  to  drive  high-powered  tetrode 
amplifiers  on  144  Mc,  and  this  triode  amplifier 
will  get  along  nicely  with  the  same.  The  9903 
driver  here  runs  at  105  watts  input  (700  volts  at 
150  ma.)  and  this  furnishes  50  ma.  grid  current 
and  270  volts  bias.  The  final  stage  will  operate 
satisfactorily  with  grid  current  as  low  as  35  ma., 
so  an  829-B  should  handle  the  job  without  ex- 
ceeding its  normal  c.w.  ratings. 

Design  Considerations 

In  laying  out  a  high-powered  amplifier  that 
requires  conventional  cross-over  neutralization, 
symmetry  and  short  leads  are  mandatory.  The 
top-view  photograph  shows  how  these  ends  are

served.  Standard  components  were  used  wherever 
possible,  the  only  handmade  items  being  the  grid 
coil,  the  plate  line,  and  the  blower  trough.  The 
last  item  doubles  as  a  submount  for  the  tube 
sockets  and  furnishes  a  low-inductance  return  for 
the  filament  by-passes. 

Considerable  time  was  spent  experimenting 
with  various  filament  by-pass  arrangements,  with 
the  result  as  shown  in  the  view  of  the  blower 
trough  and  the  filament  wiring.  Silver-mica  but- 
ton by-passes  were  mounted  close  to  each  filament 
pin,  and  the  leads  to  the  filament  transformer 
were  wound  up  into  r.f .  chokes.  Using  a  grid- 
dip  meter  as  an  r.f.  indicator,  very  httle  r.f. 
can  be  found  in  the  filament  circuit,  and 
achieving  this  end  helped  considerably  with 
the  grid-drive  problem.  With  ineffective  fila- 
ment by-passing  the  final  stage  was  harder 
to  drive;  that  is,  more  driver  output  was 
needed  for  a  given  final  stage  grid  current. 

Similar  thought  was  given  to  plate  b>'- 
passing.  Checks  on  all  available  high-voltage 
by-passes  showed  series  resonance  at  30  to 


60  Mc,  so  their  effectiveness  at  144  Mc.  is  rather 
doubtful.  The  amplifier  is  operated  without  ap- 
parent r.f.  return  in  the  plate  circuit,  as  the  rotor 
of  the  tank  capacitor  is  floating  and  there  is  an  r.f . 
choke  at  the  mid-point  of  the  plate  line.  This  is  a 
satisfactory  arrangement  with  push-pull  ampli- 
fiers and  RFCi  does  an  adequate  job  of  keeping 
r.f.  energy  out  of  the  power  leads. 

Mechanical  Work 
Details  of  the  parts  of  the  amplifier  that  must 
be  made  are  best  explained  by  the  drawings 
and  photographs.  It  will  be  seen  that  the  cooling 
fan  is  mounted  on  the  rear  wall  of  the  chassis. 
Its  flow  of  air  is  directed  around  the  tube  bases 
by  the  copper  trough,  Fig.  2,  the  opposite  end  of 
w'hich  is  closed  off.  Eight  quarter-inch  holes  are 
drilled  in  the  chassis  around  each  tube,  and  a 
small  baffle  plate  is  inserted  in  the  trough  mid- 
way between  the  two  sockets  to  equalize  the 
flow  of  air  to  each  tube.  The  fan  is  a  Dayton 
type  1C180,  supplying  approximately  50  cubic 
feet  per  minute. 

In  making  the  plate  tank  circuit  no  soldering 
is  done.  The  entire  assembly  is  bolted  together, 
and  all  components  are  silver-plated.  The  line  is 
somewhat  longer  than  necessan,',  and  a  shorting 
bar  is  provided  so  that  its  electrical  length  can  be 
adjusted.  Details  of  the  shorting  bar,  the  supports 
for  the  end  of  the  line,  and  the  contact  straps 
that  connect  to  the  tuning  capacitor  are  given  in 
Fig.  3  (page  116). 

The  brass  end  fittings  are  mounted  on  ceramic 
stand-offs  SVo  inches  high  (Millen  31004).  The 
output  coupling  link  is  supported  on  3-inch 
lengths  of  polystyrene  rod,  fs  inch  in  diameter.

standoffs.  The  neutralizing  capacitors  are  held  H

Operation 

Neutralization  of  the  amplifier  is  completely 
conventional,  following  procedure  used  on  lower 
frequencies.  It  was  found  simpler  to  neutralize 
the  rig  when  the  lead  from  the  high- voltage  power 
supply  was  disconnected  completely.  Otherwise, 
self-rectification  takes  place  in  the  tubes  when 
grid  drive  is  applied,  and  plate  current  will  flow- 


in  the  final  due  to  the  d.c.  return  path  through

if  drive  is  removed,  regardless  of  the  setting  of

A  Miniature  Mobile  Antenna 

Using  the  B.C.  Whip  for  Ham' Work 

BY  ROBERT  J.  BONEBRAKE.*  W9GCQ 


THE  reason  often  given  for  using  an  arrange- 
ment such  as  the  one  about  to  be  described 
—  "The  XYL  won't  allow  holes  drilled  in 
the  car"  —  would  probably  be  sufficient  in  this 
case  also.  However,  in  this  instance  there  were 
additional  considerations.  Originally,  a  perma- 
nent mobile  rig  was  not  installed  in  the  family 
automobile  because  we  contemplated  buying  a 
new  one  in  the  not-too-distant  future.  A  few 
months  ago  we  were  building  a  small  self-con- 
tained all-band  batter}'-  or  a.c./d.c.-powered 
receiver  and  transmitter  for  portable  use.  Having 
alwaj'S  had  the  desire  to  operate  mobile,  the  idea 
was  conceived  that  it  should  be  possible  to  use  the 
portable  rig  in  the  car,  using  either  its  self-con- 
tained batteries  or  an  inverter  to  produce  115 
volts  a.c.  from  the  6-volt  car  batterj'.  This  would 
make  possible  the  use  of  the  small  rig  as  both  a 
portable  and  mobile  rig,  except  for  one  problem 
—  what  to  use  for  a  mobile  antenna.  Since  the  rig 
would  not  be  in  the  car  permanently,  it  did  not 
seem  worth  while  to  mount  a  permanent  center- 
or  base-loaded  antenna  on  the  car.  Yet  to  get  any 
power  into  the  antenna  it  must  be  resonant,  and 
*  3027  Memphis  Street,  El  Paso,  Texas. 


•  If  there  are  objections  to  the  mounting 
of  the  conventional  8-ft.  transmitting 
antenna  on  the  family  car,  \^9GC0  tells 
here  hoM-  to  make  use  of  the  standard 
b.c.  antenna  for  mobile  operation. 


the  ordinary  auto  antenna  is  not  long  enough  to 
resonate  at  any  frequency  lower  than  the  50-Mc. 
band. 

Thus  it  was  decided  to  use  the  existing  auto 
antenna,  fully  collapsed,  as  the  bottom  section  of 
a  center-loaded  whip.  The  rest  of  the  antenna 
consists  of  a  center  insulated  section  on  which  are 
mounted  banana  jacks  for  plug-in  loading  coils, 
and  a  top  section  made  of  a  standard  auto  an- 
tenna. The  center  section  is  connected  to  the  top 
and  bottom  antenna  sections  by  two  5^6-  to 
J^4-inch  copper-tubing  reducer  fittings.  Thus  the 
center  insulated  section  and  the  top  section  can 
be  quickly  attached  to  or  removed  from  the  car 
antenna. 

It  might  be  pointed  out  at  this  time  that  in 
any  mobile  installation  where  it  is  desired  to  use 
the  existing  auto  antenna  on  the  converter,  this 
loading-coil  arrangement  can  be  used  to  advan- 
tage. On  40  meters  and  20  meters,  signals  which 
are  unreadable  using  the  standard  auto  antenna 
become  S9-plus  when  the  extension  is  attached 
and  the  proper  loading  coil  plugged  in.  In  our 
case,  since  the  portable  transmitter  has  a  very 
low-power  output,  separate  loading  coils  were 
made  for  each  band  in  the  interest  of  highest 
possible  efficiency.  However,  if  the  antenna  were 
to  be  used  onh'  for  receiving,  the  coil  could  be 
made  sufficiently  large  for  use  on  the  lowest- 
frequency  band  to  be  used,  and  tapped  down  for 
the  higher-frequency  bands. 

Construction 

The  construction  of  the  center  insulated  section 
is  shown  in  the  drawing  and  photographs.  It  was 
made  entirely  from  readily  available  parts,  since

The  center  loading  section  connected  to  the  b.c. 
antenna,  with  the  40-meter  coil  in  place.  At  the  risk  of 
somewhat  lower  efficiency,  this  single  coil  could  be 
tapped  for  use  on  the  higher-frequency  bands. 

we  did  not  have  tools  or  materials  to  do  any 
machining  of  connectors,  tapping  of  polystyrene, 
etc.  Undoubtedly,  anyone  with  proper  equipment 
could  produce  a  better  center  section  from  a 
mechanical  standpoint. 

The  bottom  section  of  ordinary  automobile  an- 
tennas is  approximately  5^6-inch  in  diameter,  and 
makes  a  fairly  close  fit  into  the  ^-inch  end  of 
the  reducer  fitting.  The  outside  diameter  of  the 
J^-inch  end  of  the  fittings  is  smaller,  thus  pro- 
viding a  larger  shoulder  to  bear  against  the  end 
plate  when  the  retaining  nut  is  tightened. 

In  normal  use  of  the  copper-tubing  fittings,  the 
nut  is  tightened  until  the  copper  compression  ring 
is  compressed  tightly  against  the  tubing,  thus 
producing  a  leakproof  seal.  In  our  apphcation, 
the  ring  cannot  be  compressed  enough  because 
the  antenna  tubing  is  slightly  smaller  than  ordi- 
nary ^6-iiich  copper  tubing.  Even  if  it  could  be. 


it  would  be  impossible  to  remove  it  easily  when 
taking  the  extension  piece  from  the  car  antenna. 
Therefore,  since  the  joint  does  not  have  to  be 
leakproof,  the  compression  rings  can  be  split 
lengthwise  on  one  side  with  a  hacksaw.  Then, 
when  the  nut  is  tightened,  the  ring  can  compress 
around  the  antenna,  closing  the  slot  made  with 
the  hacksaw,  and  clamping  tightly  to  the  antenna. 
The  copper  compression  rings  should  not  be  used 
in  the  ends  of  the  reducer  fittings  that  fasten 
permanently  to  the  end  plates. 

To  provide  more  rigidity  where  the  insulated 
center  section  clamps  to  the  bottom  antenna  sec- 
tion, a  34-inch  brass  shaft  coupling  is  soldered  or 
brazed  to  the  nut  on  the  34-inch  side  of  the  bot- 
tom reducer  fitting.  When  connecting  the  insu- 
lated section  to  the  auto  antenna,  the  center 
section  of  the  auto  antenna  is  allowed  to  extend 
up  through  the  shaft  coupling,  and  the  set  screws 
are  tightened  down  on  it. 

The  side  pieces  are  made  from  J^-inch  poly- 
styrene. Polystyrene  makes  a  good  insulator  at 
radio  frequencies,  but  it  has  a  tendency  to  dis- 
color when  exposed  to  sunhght  for  long  periods 
of  time,  and  also  may  crack  when  subjected  to 
high  pressures.  Therefore,  it  is  suggested  that 
other  types  of  insulating  materials  may  be  better 
for  this  application.  However,  we  have  used  this 
antenna  for  several  months  and  no  serious  ill 
effects  have  been  noted.  We  have  found  that  if 
the  polystyrene  is  heated  slightly  at  the  points 
where  pressure  is  applied  to  it,  the  cracking  will 
be  minimized.  For  example,  after  the  polystyrene 
pieces  have  been  bolted  to  the  end  plates,  the 
bolts  can  be  heated  slightly  with  a  soldering  iron. 
Too  much  heat,  of  course,  will  cause  excessive 
melting  of  the  polystjTene. 

The  end  plates  on  which  the  reducer  fittings  are 
mounted  are  made  of  16-gauge  cadmium-plated 
sheet  metal.  Sheet  brass,  if  available,  would  be 
better  due  to  its  increased  conductivity  and  re- 
sistance to  corrosion.  If  the  dimensions  given  in 
the  drawing  are  followed,  the  unit  must  be  as- 
sembled in  the  following  sequence  after  all  holes 
have  been  drilled:  First,  solder  the  banana  jacks 
to  the  end  plates  and  bolt  the  polystyrene  to  that 
side  of  each  plate.  Then  put  the  reducer  fittings 
on  and  bolt  the  other  piece  of  polystyrene  in. 

The  top  section  of  the  antenna  is  a  standard

Loading  Coils 

To  date,  we  have  made  loading  coils  for  40,  20, 
and  10  meters.  (A  small  coil  is  necessary  for  10 
because  the  total  length  of  the  antenna  is  not 
quite  }4:  wavelength.)  The  coils  are  made  from 
B  &  W  inductors,  as  shown  in  the  table.  After 
determining  the  proper  number  of  turns  for  each 
coil,  the  coil  was  cut  and  mounted  on  a  3^  X 
%-inch  piece  of  ^le-inch  polj'styrene,  using  Poly- 
weld  912  coil  dope,  and  banana  plugs.  The  type 
of  construction  can  be  seen  in  the  photographs. 
The  coils  were  adjusted  by  starting  with  too  much 
inductance,  and  decreasing  the  size  one  turn  at  a 
time,  tapping  the  coil  with  a  small  alligator  cUp. 
Indication  of  the  proper  inductance  was  obtained 
by  observing  the  S  meter  of  a  receiver  each  time 
the  tap  was  changed.  The  receiver  was  located 


The  loading  coils  are  mounted  on  polystyrene  strips 
fitted  with  banana  plugs. 

about  100  feet  away,  with  the  antenna  terminals 
grounded.  The  size  of  the  coils  given  in  the  table 
should  be  fairly  accurate  for  any  installation,  pro- 
vided the  length  of  the  two  antenna  sections  is  the 
same  as  ours  —  64  inches  above  the  coil,  and  20 
inches  below.  The  length  of  antenna  above  the 
coil  has  the  most  effect  on  the  required  induc- 
tance, longer  lengths  requiring  less  inductance. 
The  antenna  in  our  installation  is  fed  through  53^ 
feet  of  coaxial  cable  by  a  link  on  the  final  tank 
coil.  The  cable  consists  of  the  regular  auto  an- 
tenna lead-in,  plus  a  3-foot  extension  made  of 
RG-59/U. 

Results 

The  over-all  efficiency  of  the  antenna  seems  to 
be  quite  good.  Two-way  checks  have  been  made 
with  a  fixed  station  using  a  nondirectional  an-

Although  it  may  seem  that  the  added  weight  of 
the  loading  coil  and  antenna  extension  might 
cause  undue  strain  on  the  auto  antenna  and  its 
mount,  we  have  used  this  arrangement  for  several 
months  with  no  apparent  damage.  Since  it  takes 
but  a  matter  of  seconds  to  remove  the  extension 
from  the  auto  antenna,  or  to  telescope  the  top 
section  down,  it  can  easily  be  lowered  when  put- 
ting the  car  in  a  low  garage  or  driving  through 
low  wooded  areas.  For  even  greater  flexibiUty,  if 
desired,  the  top  extension  could  be  connected  to 
the  center  insulated  section  by  means  of  a  fle.xible 
mounting  spring,  similar  to  the  tjpe  that  is  now 
on  the  market  for  that  purpose.

Simple  Single-Band  Preamplifiers 


More  Gain  for  the  Receiver 

BY  W.  W.  DEANE,  *  W6RET 


•  The  author  fouiicl  that  this  little  fixed- 
tuned  preamplifier  helped  a  lot  in  pull- 
ing in  State-side  signals  on  his  75A-1 
Mhile  he  was  in  the  South  Pacific.  It  can 
be  duplicated  with  a  handful  of  parts 
and  a  couple  of  spare  hours. 


OCCASIONALLY  \ve  all  wish  we  could  get  a  little 
more  gain  out  of  the  receiver,  particularly 
one  not  emploj'ing  an  r.f.  stage.  A  very 
satisfactory  waj^  to  improve  the  gain  is  to  add  an 
r.f.  preamplifier  ahead  of  the  receiver.  The  ulti- 
mate, of  course,  would  be  a  bandswitching  unit 
to  cover  all  bands.  However,  the  majority  of 
hams  seem  to  confine  their  operations  to  one  or 
two  bands,  and  the  cost  and  complexity  of  con- 
structing a  switchable  unit  makes  it  desirable  to 
utilize  a  simple  preampUfier  confined  to  a  single 
band.  Fig.  1  illustrates  a  preampUfier  for  any  one 
band  from  80  to  10  meters.  It  requires  a  minimum 
of  parts,  expenditure,  or  labor,  and  will  pay  big 
dividends  in  bringing  in  a  lot  of  heretofore  un- 
heard signals. 

Con  struc  Hon 

In  the  model  illustrated,  a  6AK5  tube  was  used, 
but  there  are  several  different  tubes  that  could 
be  substituted,  such  as  the  6AG5,  6CB6,  6BC5, 
6BH6,  or  6AU6.  It  should  be  noted  that  all  of  the 
above  tubes  are  not  direct  replacements  for  the 
6AK5,  and  a  tube  manual  should  be  consulted

807s  in  a  150-Watt  Bandswitching  Rig 

Operating  Convenience  with  Medium  Power 
BY  GEORGE  G.  SYMES.  JR.,*  W3WXP/0 


•  This  150-watt  transmitter  has  a  iiuni- 
hcr  of  attractive  features.  Provision  is 
made  for  both  crystal  and  \  l'"0  opera- 
tion. The  VFO  and  multiplier  stages  are 
gang-tuned,  and  a  multiband  tuner 
requiring  no  switching  is  used  in  the 
parallel  807  final.  Other  features  include 
a  metering  system,  excitation  control, 
and  a  built-in  power  supi>ly  for  the 
driver  stages.  The  only  external  unit  re- 
quired is  the  power  supply  for  the  final. 


NOT  long  ago,  after  a  shutdown  of  some  12 
years,  I  moved  into  quarters  that  per- 
mitted resumption  of  ham  activities.  The 
old  6L6-807  band-switching  rig,  quite  modern 
when  it  was  built  15  years  ago,  was  dusted  off, 
fired  up  and  put  on  the  air.  After  replacing  a  few 
small  parts  (casualties  of  a  5-year  storage  in  sea 
air),  and  refreshing  my  memory  on  its  peculiari- 
ties, it  gave  a  good  account  of  itself.  However, 
passage  of  time  showed  up  two  serious  drawbacks. 
The  yield  of  QSOs  in  proportion  to  the  number 
of  calls  using  crystal  control  was  very  disappoint- 
ing, and  TVI  restricted  operation  to  almost 
impossible  hours. 

The  quickest  solution  seemed  at  first  to  lie 
in  an  alteration  of  the  old  rig.  But  the  more  I 
thought  about  adding  an  external  VFO,  fitting 
shielding,  installing  by-passes,  v.h.f.  filters  and 
shielded  wiring  in  already  restricted  space,  the 
more  it  seemed  desirable  to  rebuild  completely 
so  that  many  ideas  accumulated  over  later 
years  could  be  included.  Consequently,  the  rig 
shown  in  the  photographs  was  born. 

The  circuit,  shown  in  Fig.  1,  is  a  result  of 
browsing  through  the  ARRL  Handbook  and  issues 
of  QST  for  the  last  few  years.  Either  a  6AG7

Clapp  VFO  covering  1.6  to  2  Mc.  (to  include 
the  11-meter  band),  or  an  80-meter  Pierce 
crystal  oscillator  may  be  switched  {Sia)  to  feed 
a  6AG7  buffer  doubler  followed  by  a  string  of 
6.\Q5  frequency  multipliers  covering  80  through 
10  meters.  Each  stage  (excepting  the  one  covering 
14  and  21  Mc.)  covers  only  one  band  and  there- 
fore is  more  easily  stabihzed  and  adjusted  for 
optimum  performance  than  a  stage  required  to 
cover  several  bands.  Sib  and  Sic  remove  screen 
and  plate  voltages  from  the  idle  oscillator. 
These  voltages  are  held  constant  by  VR  tubes 
in  the  low-voltage  power  supply  included  in  the 
assembly. 

The  output  of  any  multiplier  stage  may  be 
switched  (Sza  —  <S2d)  to  feed  a  final  using  a 
pair  of  8078  in  parallel.  (61468  could  be  sub- 
stituted with  a  saving  in  space,  although  some 
details  might  have  to  be  altered.)  Sje  removes 
plate  and  screen  voltages  from  the  idle  multiplier 
stages.  The  multiplier  stages  are  tuned  simul- 
taneously with  the  VFO  by  ganging  their  tuning 
capacitors  (Cia  —  Cie)  to  the  VFO  frequency 
control.  Thus,  the  tuning  controls  are  reduced 
to  three,  including  the  output  coupling  control. 

The  6AG7  amplifier-doubler  doubles  frequency 
only  when  working  from  the  1.6-2-Mc.  VFO 
Crystals  in  the  3.5-Mc.  region  are  used  in  the 
crystal  oscillator,  although  160-meter  crystals 
may  be  used  if  they  are  on  hand.  The  6AQ5

inductor,  Li,  thus  reducing  the  effective  in- 
ductance for  the  higher-frequency  band. 

C2,  Ce,  Cg,  Cio,  Cn,  and  the  adjustable  slugs 
in  the  multiplier  plate  inductors  provide  con- 
venience in  adjusting  the  tracking  of  the  mul- 
tiplier circuits.  C^,  C9  and  Cn  are  included  so 
that  the  circuit  capacitances  will  remain  the 
same  whether  a  multiplier  stage  is  working  into 
the  final  amplifier  or  into  the  following  multiplier

stage.  Thia  is  necessary  to  preserve  tracking. ^ 
The  potentiometer  Ri  in  the  screen  circuit  of  the 
6AG7  buffer-doubler  is  used  to  adjust  excitation 
and  is  a  convenience  no  rig  should  be  without. 

When  the  rig  was  first  fired  up,  the  6AG7 
buffer-doubler  oscillated.  Thia  instability  was 
eliminated  by  connecting  a  second  by-pass,  C5, 
shown  in  dotted  lines,  at  the  cathode,  and 
experimentally  grounding  it  at  various  points 
on  the  chassis  until  the  right  spot  was  found. 
Slight  differences  in  wiring  or  layout  may  make 
this  unnecessary.  Another  oscillation  showed  up 
in  the  40-meter  6AQ5  stage.  This  was  cured  by  a 
1-turn  neutralizing  link,  also  shown  in  dotted 
lines.  This  link  may  or  may  not  be  required  in 
every  case. 

'At  10  meters,  the  reactance  of  the  parasitic  chokes  used 
(1  ixh.)  becomes  appreciable  relative  to  the  reactance  of  C13 
and  Ci4  plus  the  tube  input  capacitance.  This  tends  to 
increase  considerably  the  apparent  capacitance  across  the 
circuit,  and  this  is  probably  the  reason  that  the  50-^i/if. 
variable  capacitor  was  found  necessary  to  cover  the  IO- 
meter band.  It  should  be  possible  to  eliminate  v.h.f.  para- 
sitic oscillation  without  the  use  of  the  grid  chokes  (see  recent 
editions  of  The  Radio  Amateur's  Handbook).  With  the 
chokes  removed,  capacitor  values  the  same  as  those  used  in 
the  40-  and  20-meter  stages  should  be  adequate  with  an 
appropriate  increase  in  tank  inductance.  —  Ed. 

»  See  QST.  July,  1954. 

'  It  is  advisable  to  use  a  rotary  switch  at  this  point,  since 
the  switch  must  stand  the  full  807  plate  voltage.  —  Ed. 


To  avoid  switching  in  the  final  amplifier, 
a  multiband  tuner "  is  used  in  the  output  tank 
circuit.  Ss  selects  a  proper  proportion  of  the 
output  coupling  inductor,  L12,  depending  on  the 
output  frequency.  Cn  is  the  output  coupling 
control.  L7,  Ls,  Lg,  C13  and  Cu  were  installed  to 
suppress  parasitic  oscillation.  The  two  capacitors 
are  also  an  aid  in  reducing  TVI.  The  807s  are 
protected  by  a  6L6  screen  clamper.  85^  grounds 
the  screens  while  tuning  up  the  exciter. 

Two  milliammeters  are  included.  A  10-ma. 
unit,  MA  I,  may  be  switched  to  read  either  final 
grid  current  or  total  exciter  current.  The  resistor 
Ri  is  a  20-times  shunt  to  increase  the  full-scale 
reading  to  200  ma.  The  shunt  was  made  from 
copper  wire  as  described  in  the  measurements 
chapter  of  the  ARRL  Handbook.  The  second 
meter,  a  300-ma.  unit,  reads  combined  plate 
and  screen  currents  to  the  807s. 

All  power  leads  are  of  shielded  wire,  and  have 
filters  for  the  operating  frequency  as  well  as  for 
v.h.f.  The  low-frequency  filtering  may  not  be 
strictly  necessary,  but  it  does  help  to  keep 
fundamental  r.f.  out  of  the  power  supply  and 
off  the  a.c.  line  where  rectification  might  take 
place,  resulting  in  the  generation  of  TVI. 

Construction 

A  system  of  permanent  yet  flexible  construction 
was  found  in  building  the  exciter,  final  ampHfier 
and  low-voltage  power  supply  as  separate  units. 
Any  of  these  may  be  quickly  removed  from  the 
assembly  for  replacement,  rebuilding  or  use 
elsewhere.  A  pair  of  5  X  13  X  3-inch  chassis 
takes  care  of  the  low-voltage  power  supply  and 
the  final  amplifier.  The  exciter  is  assembled  in  a 
12  X  7  X  4-inch  ICA  "  Flexi-mount "  box. 

In  the  exciter  unit,  the  VFO  occupies  the 
front  end,  with  the  tuning  capacitor  Cia  enclosed 
in  an  aluminum  box  on  top,  and  the  inductor 
Li  mounted  underneath  on  a  small  stand-off 
insulator  fastened  against  the  front  wall.  In  the 
rear/top  view,  the  crystal  and  crystal-oscillator 
tube  are  to  the  right  of  the  tuning-capacitor  box, 
and  the  VFO  tube  is  to  the  left,  followed  by  the 
string  of  multiplier  tubes.  The  10-meter  stage

attached  to  the  tail  shaft  of  the  VFO  tuning 
capacitor,  Cia  above,  and  another  gear  on  the 
shaft  of  the  first  multipher  tuning  capacitor, 
CiB,  below.  The  gears  engage  through  a  slot  cut 
in  the  chassis.  (I  may  say  that  this  arrangement 
is  not  as  satisfactory^  as  it  might  be  and  if  I  were 
going  to  do  the  job  again,  I  would  mount  the 
entire  gang  on  top  of  the  chassis,  cover  it  with 
a  long  narrow  box  of  aluminum,  and  feed  the 
stator  leads  through  holes  to  the  switch  sections 
below.) 

The  bandswitch,  with  the  wafers  spaced  ap- 
proximately according  to  the  tube  spacing,  is 
mounted  between  a  partition  that  shields  the 
VFO  from  the  rest  of  the  exciter,  and  the  rear 
wall  of  the  box.  The  last  wafer,  S2E,  is  mounted 
on  the  outside  of  the  box.  The  partition  shielding 
the  VFO  also  serves  as  a  mounting  for  the 
crystal-VFO  switch.  Si,  and  the  excitation  con- 
trol, Ri. 

In  the  bottom  view,  the  inductors  for  the 
multiplier  stages  and  the  padder  capacitors, 
Ce,  Cg,  Cio  and  C12,  are  to  the  right  of  the  band- 
switch.  The  tube  sockets  and  the  grid  trimmer 
capacitors,  C7,  Cg,  and  Cn,  are  to  the  left.  The 
VFO  trimmer,  C2,  is  to  the  right,  close  to  the 
front  wall  of  the  chassis.  (Its  control  shaft  is 
behind  the  crystal-oscillator  tube  in  the  rear 
view.) 

A  1-inch  extension  of  aluminum  is  attached 
to  the  rear  of  the  exciter  box  to  make  its  over-all 
length  13  inches  to  match  the  adjacent  chassis. 
The  r.f.  filter  componentB  and  the  6AQ5  ecreen 


resistors  (as  well  as  the  last  section  of  the  band- 
switch,  iSoe),  are  placed  inside  the  enclosure, 
and  the  compartment  is  fitted  with  a  cover 
plate  of  aluminum.  A  terminal  strip  is  set  in  the 
upper  edge. 

Capacitor  Gang 

In  building  this  unit,  I  made  use  of  components 
on  hand  whenever  possible.  The  condenser  gang, 
Ci,  is  made  up  of  individual  capacitors  connected 
together  with  shaft  couplers.  Care  must  be  used 
in  selecting  capacitors  that  will  fit  into  the  length 
of  the  "Flexi-mount"  box.  One  inch  must  be 
allowed  for  the  hub  of  the  National  ACN  dial, 
leaving  only  11  inches  for  the  tuning  gang. 
A  suitable  gang  can  be  made  up  of  Bud  "Tiny- 
Mite"  dual  capacitors.  A  dual  25-fxiJ.L  unit  (LC- 
1661)  with  its  sections  connected  in  parallel  will 
serve  for  Cia-  A  dual  50-Mjuf.  unit  (LC-1662)  can 
be  used  for  Cib  and  C\c-  Five  plates  (3  rotor  and 
2  stator)  should  be  removed  from  the  Cic  section. 
Another  dual  50-MMf-  unit  can  be  used  for  Cm 
and  CiE,  removing  plates,  as  above,  for  Cm. 

Amplifier 

The  amplifier  is  enclosed  in  a  homemade 
aluminum  box  fastened  to  the  top  of  the  5  X  13 
X  3-inch  chassis.  The  box  is  4)^  inches  high 
(limited  by  the  height  of  the  8%-inch  panel), 
the  same  width  as  the  chassis,  and  long  enough 
to  include  the  807s  and  the  multi-band  tank- 
circuit  components,  yet  leave  sufficient  room  for 
the  6L6  clamper  tube  in  front  and  a  terminal 
strip  at  the  rear.  The  sides  and  top  are  perforated 
to  provide  ventilation.  The  tuning  capacitor 
Ci4  and  the  output  inductors  Lio,  Ln  and  L12, 
are  placed  centrally  in  the  box,  and  as  far  toward 
the  front  as  possible.  The  capacitor  is  mounted 
directly  on  the  front  wall  of  the  box,  and  rests 
against  the  chassis.  In  an  effort  to  reduce  the 
length  of  the  path  between  the  rotor  of  the 
capacitor  and  the  807  cathodes,  short  leads  from 
each  end  of  the  rotor  were  brought  through 
holes  and  fastened  to  the  under  side  of  the 
chassis.  To  allow  room  for  the  300-ma.  meter, 
which  has  a  2} ^-inch-diameter  flange,  the  dial

must  be  set  bo  low  on  an  8^-inch  panel  that  it 
is  necessary  to  use  a  flexible  shaft  between  the 
dial  and  the  tuning-capacitor  shaft.  With  a 
10%-inch  panel  this  would  not  be  a  problem,  of 
course. 

Holes  to  clear  the  bases  of  the  8078  are  cut  in 
the  top  of  the  chassis,  and  the  sockets  are  sub- 
mounted,  on  a  U-shaped  strip  of  aluminum, 
to  a  depth  that  brings  the  caps  of  the  807s  clear 
of  the  top  cover  of  the  box.  Here  again,  a  10%- 
inch  panel  might  provide  greater  freedom  in  the 
method  of  mounting.  Millen  shield  cans  are 
used  with  the  tubes. 

Inductors 

The  inductors  were  originally  all  made  from 
B  &  W  3907  strip  inductor  stock  as  shown  in  the 
top  view,  simply  opening  up  the  winding  where 
necessary  to  provide  the  proper  terminals.  How- 
ever, the  high-frequency  secition,  Ln,  ran  warm 
enough  to  soften  the  plastic  supporting  strips. 
This  difficulty  was  solved  later  by  making  Ln  a 
separate  section,  wound  on  a  ceramic  form. 
Similar  forms  may  be  hard  to  come  by,  but  it 
should  not  be  too  difficult  to  make  a  self-support- 
ing coil  of  the  same  inductance,  since  the  dimen- 
sions are  small.  The  output  coupling  inductor, 
L12,  should  be  placed  between  Lio  and  La- 

The  output-link  switch,  S3,  and  the  link 
tuning  capacitor,  Cn,  are  mounted  under  the 
chassis,  as  shown  in  the  bottom-view  photograph. 

Shielded  phonograph  jacks  are  mounted  near 
the  rear  ends  of  the  exciter  and  amplifier  chassis 


and  are  connected  with  a  short  length  of  RG- 
59 /U  coax  fitted  with  phonograph  plugs. 

Power  Supply 

The  low-voltage  power  supply  is  built  on  the 
second  5  X  13  X  3-inch  chassis.  The  circuit  is 
shown  in  Fig.  2.  The  arrangement  of  components 
is  not  critical  so  long  as  they  are  accommodated 
in  the  available  space.  This  section  includes 
the  10-ma.  meter  and  its  switch,  indicator  lights 
for  filament  and  plate  voltage,  and  a  pair  of  toggle 
switches  to  control  these  supplies.  The  high- 
voltage  supply  is  conventional,  using  choke 
input  and  a  transformer  rated  at  600  or  750  v. 
d.c,  200  to  300  ma. 

Adjustment 

After  checking  the  crystal  oscillator  to  make 
sure  that  it  is  functioning  properly,  the  VFO 
should  be  checked  and  its  tuning  range  adjusted 
to  cover  the  desired  range  of  frequencies.  Setting 
Ci  to  minimum  capacitance,  C2  should  be  ad- 
justed until  the  oscillator  is  heard  at  4000  kc, 
or  a  few  kc.  higher.  Then,  with  the  bandswitch 
in  the  80- meter  position,  and  the  milliammeter 
reading  grid  current  to  the  807s,  Cg  should  be 
set  at  midscale  (Ci  still  at  minimum  capacitance) 
and  the  slug  in  Lo  adjusted  for  maximum  807 
grid  current.  Then  Ci  should  be  adjusted  until 
the  oscillator  signal  is  heard  at  3200  kc,  and 
Ce  readjusted  for  maximum  grid  current.  If  this 
last  adjustment  requires  an  increase  in  the 
capacitance  of  Cq,  the  tuning  range  of  the  80-

Ripple  on  the  S.S.B.  Scope  Pattern 


IT  IS  well  known  that  a  perfect  single-tone  single- 
eideband  signal  consists  of  but  a  single 
radio  frequency.  When  such  a  signal  is  displayed 
on  the  face  of  a  'scope  being  swept  horizontally 
at  an  audio-frequency  rate,  the  pattern  is  a 
horizontal  band  having  perfectly  smooth  and 
straight  upper  and  lower  edges.  It  is  identical 
with  the  pattern  of  any  unmodulated  carrier. 

If  the  suppression  of  the  other  sideband  or 
the  carrier  is  not  complete,  the  edges  of  the 
pattern  show  a  ripple.  Assuming  that  the  carrier 
is  completely  suppressed,  the  relationship  be- 
tween the  desired  and  undesired  side  frequencies 
can  be  represented  by  the  phasor  ^  diagram 
shown  in  Fig.  1.  AB  represents  the  amplitude 


X 


\  Fig.    1  —  The    mechanism 

I  by  which  the  undesired  side 

/  frequency   makes  a  "ripple" 

on  the  desired  side  frequency 
of  an  s.s.b.  signal.  Other  pos- 
sible spurious  components  are 
neglected  in  this  drawing,  but 
can  be  included  if  their  rela- 
tive amplitudes,  phases,  and 
frequency  separation  from  the 
desired  side  frequency  are 
known. 


of  the  desired  side  frequency  and  BC  the  am- 
plitude of  the  undesired  side  frequency.  The 
latter  rotates  with  respect  to  AB,  with  C  de- 
scribing the  dashed  circle.  The  rate  of  rotation  is 
equal  to  twice  the  audio  modulation  frequency 
since  the  two  frequencies  are  separated  in  the 
spectrum  by  that  number  of  cycles.  At  some 
instant  during  each  such  period  of  rotation  point 
C  will  reach  X  and  the  total  instantaneous  am- 
plitude will  be  the  distance  AX.  A  half-period 
later  C  will  coincide  with  Y  and  the  total  in- 
stantaneous amplitude  will  be  AY.  As  displayed 
on  the  face  of  the  'scope,  this  time  variation  is 
transformed  into  a  ripple  along  the  horizontal 
edges  of  the  pattern,  the  maximum  vertical 
excursions  lying  between  A  Y  and  AX. 

Since  the  relative  amplitudes  of  the  desired 
and  undesired  are  AB  and  BC,  respectively,  the 
ratio  of  desired  to  undesired  is  AB/BC.  This 
amplitude  ratio  is  also  equal  to  twice  the  length 
AB  divided  by  the  distance  XY.  In  terms  of  the 

^  The  term  "pliasor"  is  not  used  in  an  attempt  to  confuse 
the  reader,  but  to  conform  with  a  recommendation  of 
I.R.E.  "Phasor"  is  preferred  to  "vector"  because  while 
the  vector  representation  is  convenient  for  showing  relative 
phase  and  amplitude  of  a.c.  currents  and/or  voltages, 
these  quantities  are  not  actually  vectors  —  that  is,  there  is 
no  spatial  direction  associated  with  them. 


'scope  pattern,  this  means  that  the  average 
height  of  the  pattern  divided  by  the  vertical 
distance  between  a  peak  and  valley  of  the  ripple 
gives  the  ratio  by  which  the  undesired  side 
frequency  is  suppressed. 

Fig.  2  shows  these  quantities  as  they  appear  on 
the  tube  face,  together  with  typical  patterns 
for  various  ratios  of  spurious  suppression.  The 
latter  are  drawn  as  closely  to  scale  as  possible, 
and  therefore  can  serve  as  a  guide  to  estimating 
spurious  suppression  without  actual  measure- 
ment and  calculation. 

In  examining  such  a  pattern,  it  is  necessary 
that  the  horizontal  sweep  in  the  'scope  be 
synchronized  at  some  submultiple  of  the  modula- 
tion frequency  in  order  to  get  a  stationary  pic- 
ture. Without  such  synchronization  the  ripple 
becomes  merely  a  blur.  Since  the  edge  of  the 
blur  is  a  straight  line,  the  unwary  operator  can 
lead  himself  to  believe  he  has  a  "perfect"  s.s.b. 
transmitter  when  in  actuality  it  may  be  pretty 
poor. 

It  is  also  necessary,  although  it  should  not  be, 
to  emphasize  that  the  audio  gain  must  be  kept 
below  the  point  where  any  stage  in  the  trans- 
mitter tends  to  saturate.  Saturation  of  an  am- 
plifier gives  a  beautiful  pattern,  but  unfortu- 
nately, the  actual  output  contains  all  sorts  of 
spurious  that  the  'scope  can't  show. 

Total  Spurious 

The  actual  situation  in  a  practical  transmitter 
is  not  quite  so  simple  as  it  has  been  outlined 
above.  The  assumption  that  the  transmitter 
output  consists  only  of  the  desired  side  frequency 
and  its  undesired  "image"  can  seldom  be  justi- 
fied in  practice.  There  are  always  other  compo- 
nents present  in  the  transmitted  signal  even 
when  the  audio  input  is  ostensibly  a  single  tone. 
These  are  (1)  the  residual  carrier,  if  it  is  not 
balanced  out  to  considerably  better  than  40  db. 
below  the  desired  side  frequency;  (2)  compo- 
nents resulting  from  harmonic  distortion  either 
in  the  audio  input  signal  or  added  to  the  signal 
in  the  speech  amplifier  and  modulator;  (3) 
intermodulation  components  generated  in  r.f. 
stages. 

These  components  have  a  definite  frequency 
spacing  in  the  spectrum,  always  appearing  at 
some  multiple  of  the  audio  modulation  fre- 
quency on  one  side  or  the  other  —  or  on  both 
sides  — ■  of  the  carrier  frequency.  The  amplitudes 
of  the  last  two,  at  least,  can  easily  exceed  the 
amplitude  of  the  undesired  side  frequency  in  a 
well-designed  single-sideband  transmitter.  What 
the  'scope  shows,  consequently,  is  the  composite 
of  all  the  spurious  components  present. 

As  a  result,   the  actual  shape  of  the  ripple

along  the  edge  of  the  pattern  is  seldom  as  con- 
ventionally sinusoidal  as  the  ripple  in  the  draw- 
ings of  Fig.  2.  The  ripple  peaks  are  a  measure 
of  the  total  effect  in  about  the  same  way  that 
the  corresponding  peak-to-peak  variations  are  a 
measure  of  the  total  effect  of  an  ordinary  a.m. 
signal  displayed  on  a  'scope.  That  is,  when  the 
a.m.  signal  is  tuned  in  in  the  normal  way,  with 
the  beat  oscillator  off,  using  a  receiving  band- 
width large  enough  to  accept  the  entire  trans- 
mitted spectrum,  the  audio  output  is  the  total 
effect  of  the  variations  seen  in  the  'scope  pattern. 
If  the  s.s.b.  signal  is  tuned  in  similarly  (using  the 
desired  side  frequency  as  the  carrier)  the  audio 
output  from  the  signal  is  the  total  effect  of  the 
ripple. 

No  one  component  of  the  several  always  pres- 
ent in  an  actual  signal  can  be  separated  readily 
from  the  others  in  the  'scope  pattern.  To  do 
this  requires  a  "spectrum  analyzer"  such  as  a 
receiver  having  sufficient  selectivity  for  the 
purpose.  Also,  the  peak-to-peak  ripple  as  shown 
by  the  'scope  is  usually  less  than  the  arithmetic 
sum  of  the  individual  components  that  make  up 
the  composite  signal  because  of  the  non-uniform 
phase  relationship  between  components.  How- 
ever, it  is  not  likely  that  any  single  component 
would  have  an  amplitude  greater  than  that  of 
the  composite  ripple.  Hence  the  latter  would 
appear  to  offer  a  reasonable  basis  for  rating  the 
desired /spurious  ratio  of  the  transmitter.  As 
compared  with  other  methods  of  rating  that 
might  be  chosen,  it  has  the  advantage  of  being 
readily  measured  with  the  conventional  'scope 
set-up. 

A  desired/spurious  ratio  not  exceeding  30 
db.  at  any  audio  frequency  within  the  nominal 


3A/VW 

a.f.  band  of  the  transmitter  can  be  achieved 
if  the  transmitter  is  adjusted  and  operated  with 
reasonable  intelligence.  On  a  pattern  having  an 
average  height  of  2  inches  (typical  of  a  5-inch 
'scope)  the  peak-to-peak  ripple  height  is  3^6 
inch  for  a  30-db.  ratio.

The  T-90  Transmitter 


ALTHOUGH  the  T-90  transmitter  can  be  used  in 
L\  mobile,  portable  or  fixed  locations,  it  is 
■'-^  apparent  that  mobile  considerations  were 
paramount  when  it  was  designed.  The  packaging 
and  shape  are  such  that  it  should  fit  easily  under 
any  dashboard,   and   the  scheduled  companion 


The  T-90  covers  80  through  10  meters  with  VFO  or 
crystal  control,  'phone  or  c.w.  Here  it  is  out  of  its  case 
—  the  audio  section  is  in  the  foreground  and  the  6146 
output  stage  is  at  the  upper  left,  behind  the  shield.  The 
switch  mounted  above  the  chassis  (upper  center)  selects 
the  fixed  capacitors  in  the  output  of  the  pi-tank  circuit. 
The  antenna  relay  can  be  seen  right  next  to  it. 


receiver  in  the  same  sized  package  further  con- 
firms the  viewpoint.  However,  it  isn't  fair  to  label 
this  a  "mobile"  transmitter  and  give  the  im- 
pression that  home-station  operation  has  thus 
in  some  way  been  compromised,  because  the 
T-90  is  a  full  station  within  its  tube  capabiUties. 
A  built-in  antenna  relaj^  and  the  aforementioned 
packaging  simply  means  that  j^ou  don't  have  to 
add  extra  gadgets  when  j-ou  put  this  home  sta- 
tion in  your  car. 

The  transmitter  falls  just  under  the  100-watt 
class,  since  the  rated  d.c.  input  to  the  output- 
stage  6146  is  90  watts  on  c.w.  and  75  watts  on 
'phone.  A  glance  at  the  block  diagram  in  Fig.  1 
will  show  a  lot  more  than  a  mess  of  words,  and 
you  can  see  that  the  tube  line-up  is  similar  to 
other  transmitters  in  this  class.  A  6AQ5  clamp 
tube  is  included  to  protect  the  6146  by  holding 
the  screen  voltage  down  when  there  is  no  excita- 
tion, and  6AQ5s  are  used  in  the  two  fixed-tuned 
amplifier /multiplier  stages  as  well.  The  oscillator 
job  (VFO  or  crystal)  is  delegated  to  a  6CL6,  and 
its  voltages  are  regulated  by  the  0B2  to  minimize 
frequency  changes  with  changes  in  line  voltage. 
The  r.f.  section  can  be  keyed  in  either  the  oscilla- 
tor and  first  amplifier /multiplier  stage  cathodes 
or  in  the  cathode  of  the  first  amplifier/multiplier 
alone,  depending  upon  your  preference  and  the 
setting  of  a  function  switch  on  the  panel  that  also 
cuts  in  the  modulator  for  'phone  work. 

The  audio  portion  starts  with  a  6AU6  speech 
amplifier,  with  a  chassis-mounted  switch  that 
permits  either  carbon  or  high-impedance  crystal 
or  djaiamic  microphone  to  be  used.  This  is 
followed  by  a  6AQ5  driver  and  a  pair  of  6AV5 
modulators.  A  negative  feed-back  loop  around

QST  for 


the  driver  stage  is  included,  and  it  may  account 
for  the  good  quality  we  observed  when  the  unit 
was  checked  on  'phone. 

The  front  panel  of  this  compact  (12^^8  wide 
bj"  103^  deep  by  6^  inches  high)  unit  has  a 
couple  of  departures  from  usual  practice.  The 
first  that  hits  your  ej'e  is  the  apparent  lack 
of  a  VFO  tuning  knob!  You  stop  worrying  about 
this  when  you  discover  that  the  VFO  tuning  and 
the  bandswitch  are  concentric  controls  (a  la 
TV),  a  dodge  that  makes  for  an  uncrowded 
panel.  The  audio  gain  control,  instead  of  a  large 
knob  matching  the  others  in  size,  is  a  small 
knurled  shaft  that  can  hardly  be  seen.  And  why 
not?  —  the  audio  volume  control  on  a  trans- 
mitter doesn't  get  the  steady  handling  that  a 
receiver  volume  control  does.  The  rest  of  the 
controls  are  what  you  would  expect  on  a  trans- 
mitter of  this  type:  a  meter  switch  for  the  r.f. 
grid  and  plate  current  and  the  modulator  cathode 
current,  a  TUNE-CW-HET-PHONE  switch 
(TUNE  reduces  power  to  the  output  stage  and 
disables  the  modulator,  and  HET  turns  on  the 
VFO  for  frequency  spotting  or  amplifier-only 
keying),  a  DRIVE  switch  for  varying  excitation 


Fig.  2  —  Simplified  oscillator  circuit  of  the  T-QO. 
V  hen  using  VFO,  the  crystal  socket  requires  a  shorting 
plug.  When  crystal  control  is  used,  the  VFO  tuned  cir- 
cuit can  be  used  to  "pull"  the  crystal  frequency  slightly 
and  thus  "zero  in"  on  a  net  frequency. 

by   changing   the   screen   voltage   to   the   driver 
stage,  and  PLATE  and  ANT  tuning. 

The  ANT  tuning  control  is  more  than  meets 
the  eye.  Since  a  pi-network  output  circuit  is 
used,  there  is  the  normal  need  for  a  wide  varia- 
tion in  output  capacitance.  In  the  T-90,  the 
control  turns  the  rotor  of  a  150-MA'f-  variable 
capacitor.  On  the  far  end  of  the  rotor  shaft  there 
is  a  pin  that  engages  a  spoke  on  a  switch  shaft 


An  additional  shield  cover  has  been  removed  to  show 
the  VFO  compartment  (lower  center).  The  hub  and 
spokes  at  the  center  left  drive  the  output-capacitor 
switch  shown  in  another  photograph.  The  spokes  are 
driven  by  an  arm  on  the  shaft  of  the  output  tuning 
capacitor  at  the  lower  left. 


This  close-up  view  of  the  6146  output  stage  shows  the 
plate  tuning  capacitor  and  the  three  sections  of  tin- 
output  inductor. 

once  every  revolution.  Thus  each  time  the  capaci- 
tor shaft  makes  a  full  revolution,  more  or  less 
fixed  capacitance  is  also  thrown  into  the  circuit 
via  the  switch.  This  tricky  little  device  can  be 
seen  in  one  of  the  photograi)hs. 

When  cr3'Stal-contrull('il  operation  is  desired. 
the  crystals  can  be  changed  from  the  front  panel 
by  removing  the  crystal  access  door  on  the  nanel 
and  plugging  in  the  desired  crystal.  When  VFO 
operation  is  used,  a  shorting  plug  is  required  in 
the  crystal  socket.  The  oscillator  circuit  is  shown 
in  Fig.  2  —  it  is  a  little  unusual  in  that  the  VFO 
tuned  circuit  is  used  to  "rubber"  the  crj'stal  and 
jx»rmit  its  frequency  to  be  pulled  slightly. 

Two  power  supplies  are  available  for  use  with 
the  T-90.  The  APS-90  is  for  use  in  fi.xed-station 
operation  and  works  from  the  115-volt  6()-cycle 
line,  and  the  VPS-90  vibrator  supply  is  designed 
to  furnish  the  necessary  power  from  either  a  6.3- 
or  12.6-volt  d.c.  source. 

The  T-90  is  a  product  of  Harvey- Wells  Elec- 
tronics, Inc.

ELECTION  NOTICE 

To  All  Full  Members  of  the  American  Radio 
Relay  League  Residing  in  the  Atlantic,  Cana- 
dian, Dakota,  Delta,  Great  Lakes,  Midwrest, 
Pacific  and  Southeastern  Divisions. 

An  election  is  about  to  be  held  in  each  of  the 
above-mentioned  divisions  to  choose  both  a 
director  and  a  vice-director  for  the  1956-1957 
term.  These  elections  constitute  an  important 
part  of  the  machinery  of  self-government  of 
ARRL.  They  provide  the  constitutional  oppor- 
tunity for  members  to  put  the  direction  of  their 
association  in  the  hands  of  representatives  of 
their  own  chosing.  The  election  procedures  are 
specified  in  the  By-Laws.  A  copy  of  the  Articles 
of  Association  and  By-Laws  will  be  mailed  to 
any  member  upon  request. 

Nomination  is  by  petition,  which  must  reach 
the  Headquarters  by  noon  of  September  20th. 
Nominating  petitions  are  hereby  solicited.  Ten 
or  more  Full  Members  of  the  League  residing  in 
any  one  of  the  above-named  divisions  may  join 
in  nominating  any  eligible  Full  Member  residing 
in  that  division  as  a  candidate  for  director  there- 
from, or  as  a  candidate  for  vice-director  there- 
from. No  person  may  simultaneously  be  a  candi- 
date for  both  offices;  if  petitions  are  received 
naming  the  same  candidate  for  both  offices,  his 
nomination  will  be  deemed  for  director  only  and 
his  nomination  for  vice-director  will  be  void. 
Inasmuch  as  all  the  powers  of  the  director  are 
transferred  to  the  vice-director  in  the  event  of  the 
director's  resignation  or  death  or  inability  to 
perform  his  duties,  it  is  of  as  great  importance  to 
name  a  candidate  for  vice-director  as  it  is  for 
director.  The  following  form  for  nomination  is 
suggested: 

Executive  Committee 

The  American  Radio  Relay  League 
West  Hartford  7,  Conn. 

We,  the  undersigned  Full  Members  of  the  ARRL  residing 

in  the    Division,   hereby 

nominate of 

as  a  candidate  for  director;  and  u'e  also  nominate 

of as  a  candidate  for  vice- 
director:  from  this  division  for  the  1956-1957  term. 

{Signatures  and  addresses) 

The  signers  must  be  Full  Members  in  good  standing. 
The  nominee  must  be  a  Full  Member  and  the  holder  of  an 
amateur  license,  and  must  have  been  a  member  of  the 
League  for  a  continuous  term  of  at  least  four  yaars  at  the 
time  of  his  election.  No  person  is  eligible  who  is  commercially 
engaged  in  the  manufacture,  sale  or  rental  of  radio  apparatus 
capable  of  being  used  in  radio  communications,  or  is  com- 
mercially engaged  in  the  publication  of  radio  literature  in- 
tended in  whole  or  in  part  for  consumption  by  radio 
amateurs. 

All  such  petitions  must  be  filed  at  the  headquarters  office 
of  the  League  in  West  Hartford,  Conn.,  by  noon  EDST  of 
the  20th  day  of  September,  1955.  There  is  no  limit  to  the 


number  of  petitions  that  may  be  filed  on  behalf  of  a  given 
candidate  but  no  member  shall  append  his  signature  to 
more  than  one  petition  for  the  office  of  director  and  one 
petition  for  the  office  of  vice-director.  To  be  valid,  a  petition 
must  have  the  signature  of  at  least  ten  Full  Members  in 
good  standing;  that  is  to  say,  ten  or  more  Full  Members 
must  join  in  executing  a  single  document;  a  candidate  is  not 
nominated  by  one  petition  bearing  six  valid  signatures  and 
another  bearing  four.  Petitioners  are  urged  to  have  an  ample 
number  of  signatures,  since  nominators  are  occasionally 
found  not  to  be  Full  Members  in  good  standing.  It  is  not 
necessary  that  a  petition  name  candidates  both  for  director 
and  for  vice-director  but  members  are  urged  to  interest 
themselves  equally  in  the  two  offices. 

League  members  are  classified  as  Full  Members  and  Asso- 
ciate Members.  Only  those  possessing  Full  Membership 
may  nominate  candidates  or  stand  as  candidates;  members 
holding  Associate  Membership  are  not  eligible  to  either 
function. 

Voting  by  ballots  mailed  to  each  Full  Member  will  take 
place  between  October  1st  and  November  20th,  except  that 
if  on  September  20th  only  one  eligible  candidate  has  been 
nominated,  he  will  be  declared  elected. 

Present  directors  and  vice-directors  for  these  divisions 
are  as  follows:  Atlantic:  Gilbert  L.  Crossley,  W3YA,  and 
Charles  O.  Badgett,  W3LVF.  Canadian:  Alex  Reid,  VE2BE, 
and  Reginald  K.  Town,  VE7AC.  Dakota:  Alfred  M.  Gowan, 
W0PHR,  and  Forrest  Bryant,  W0FDS.  Delta:  George  H. 
Steed,  W5BUX,  and  George  S.  Acton,  W5BMM.  Great 
Lakes:  John  H.  Brabb,  W8SPF,  and  Robert  L.  Davis, 
W8EYE.  Midwest:  William  J.  Schmidt,  W0OZN,  and  James 
E.  McKim,  W0MVG.  Pacific:  Harry  M.  Engwicht,  W6HC, 
and  (no  vice-director).  Southeastern:  James  P.  Born,  jr., 
W4ZD,  and  Randall  E.  Smith,  W4DQA. 

Full  Members  are  urged  to  take  the  initiative  and  to 
file  nomination  petitions  immediately. 

For  the  Board  of  Directors:

F.C.C.  NOTES 

Richard  A.  Mack,  for  some  years  a  member 
of  the  Florida  Railroad  &  Public  Utilities  Com- 
mission, has  been  appointed  to  the  Federal 
Communications  Commission.  He  replaces  Miss 
Frieda  Hennock,  whose  term  expired  June  30th; 
she  is  returning  to  law  practice. 

Edwin  L.  White,  W4AS,  since  its  establish- 
ment in  1950  the  Chief  of  FCC's  Safety  &  Special 
Radio  Services  Bureau  (parent  bureau  for  the 
amateur  service)  retired  July  31st  from  many 
years  of  government  service.  His  successor  is 
Curtis  B.  Plummer  (e.x-W3KRK),  former  head 
of  the  Broadcast  Bureau. 

"WT"  PREFIX  DENIED 

A  Texas  amateur  recently  petitioned  the  Com- 
mission to  include  the  letter  "T"  in  the  prefix 
of  call  signs  issued  to  Technician  Class  amateurs 
"for  the  purpose  of  distinguishing  this  class  of 
amateur  radio  station  from  other  classes  of 
amateur  radio  stations  and  discouraging  un- 
authorized operation  by  Technician  Class  sta- 
tions in  frequency  bands  allocated  for  the  ex- 
clusive use  of  higher  class  amateur  radio  stations." 


46 


QST  for 


FCC  has  denied  it,  sa3ang  that  adoption  "would 
require  the  modification  of  approximately  12,207 
Technician  Class  Amateur  Radio  Stations,  and 
with  the  ever  increasing  work  load  in  the  Com- 
mission and  with  the  limited  personnel  available, 
the  administrative  difficulties  created  by  the 
adoption  thereof  would  not  be  justified  by  the 
benefits,  if  any,  derived  therefrom." 

F.C.C.  APPLICATIONS 

Amateur  applicants  commonly  suffer  nervous- 
ness in  taking  the  code  test;  they  apparently  are 
similarly  afflicted  when  filling  out  application 
forms.  FCC's  licensing  branch  has  recently  had 
more  trouble  than  usual  with  errors  in  applies^ 
tion  blanks,  including  renewals.  Many  appli- 
cants, undoubtedly  through  oversight  or  care- 
lessness, fail  to  answer  the  question,  "Are  you  a 
representative  of  an  alien  or  of  a  foreign  govern- 
ment?" Many  fail  to  notarize.  Many,  in  the 
case  of  renewals,  omit  necessary  data  such  as 
place  and  date  of  birth,  apparently  figuring  FCC 
already  has  this  information  (it  does,  but  the 
info  is  usually  required  for  positive  identification 
of  the  application).  And  you'd  be  surprised  how 
many  fellows  fill  out  "date  of  birth"  with  the 
proper  month  and  date  —  but  with  the  year 
1955! 

We  can  all  help  ourselves  by  helping  FCC  —  be 
careful  that  your  application  is  completely  and 
accurately  filled  out  so  that  processing  will  not 
be  delayed. 

LAOS  OFF  BANNED  LIST 

In  mid-July  FCC  announced  that  the  govern- 
ment of  Laos  has  withdrawn  its  objection,  earli(M- 
filed  with  the  International  Telecommunications 
Union,  to  communication  between  its  amateurs 
and  the  rest  of  the  world.  The  prefix  is  XW8, 
and  work  with  these  stations  is  now  permissible. 

THIRD-PARTY  TRAFFIC 

In  the  handling  of  third-party  traffic  inter- 
nationally, aside  from  countries  where  special 
agreements  exist  (Canada,  Chile,  Cuba,  Ecuador, 
Liberia,  Peru)  we  have  had  a  convenient  rule-of- 
thumb  that  traffic  is  permissible  with  any  ama- 
teur station  possessing  a  one-  or  two-letter  W  or 
K  prefix.  There  is  now  an  exception:  KA.  The 
Japanese  government  has  indicated  that  it  wishes 
privileges  available  to  all  amateur  stations  in  its 
country  to  be  uniform ;  inasmuch  as  J  As  of  course 
have  no  third-party  privileges,  the  KAs  in  Japan 
are  now  also  restricted  from  such  activity.  Other 
prefixes,  even  in  the  same  area,  are  not  affected; 
e.g.,  Okinawa,  with  the  prefix  KR6,  is  still  okaj- 
for  traffic. 

RTTY  SHIFT 

The  ARRL  Board  of  Directors  at  its  May 
meeting  instructed  the  General  Manager  to  file, 
subject  to  an  investigation  as  to  its  feasibilit}^, 
a  request  with  the  Federal  Communications 
Commission  to  amend  the  amateur  rules  so  as  to 
permit  frequency  shifts  of  less  than  the  present

DEBURRING  TOOLS 

JAGGED  BURRS  around  screw,  ventilation,  bezel 
and  socketlholes  are  not  only  unsightly  indicators 
of  poor  workmanship  but  also  constitute  a  con- 
siderable hazard,  as  the  burrs  have  and  retain 
razor-sharp  edges. 

Deburring  is  an  irritating  and  time-consuming 
job  under  most  conditions  because  of  lack  of 
suitable  tools.  With  soft  metals,  a  knife  blade  is 
partially  satisfactory,  but  may  slip  out  of  the 
hole  being  deburred,  cutting  a  deep  gouge  in  the 
panel,  or  a  gash  in  the  hand.  Small  hand  grinders 
are  somewhat  more  satisfactory,  at  a  cost  of  about 
$25.00  each,  plus  about  one  cent  per  hole  for 
wheel  replacement.  Metal  countersinks  have 
been  used,  but  these,  having  a  55-  or  60-degree 
included  angle,  ream  the  hole  almost  as  fast  as 
they  remove  the  burr. 

Quite  satisfactory  deburring  can  be  done 
with  a  carpenter's  wood  countersink  having  an 
included  angle  of  approximately  90  degrees. 
These,  which  come  in  all  sizes  up  to  about  % 
inch  in  diameter,  are  supplied  with  a  square 
shank.  To  convert  a  carpenter's  wood  counter- 
sink into  a  deburring  tool,  grind  off  the  corners 
of  the  shank  and  drive  the  shank  into  a  plastic 
screwdriver  handle  from  which  the  blade  has  been 
pulled. 

Performance  will  be  most  satisfactory  if  the 
axes  of  the  handle  and  of  the  countersink  coin- 
cide. Length  of  the  finished  tool  should  be  ap- 
proximately six  inches,  with  a  tolerance  of  about 
plus  or  minus  one  inch  to  suit  the  materials 
available  and  the  user's  personal  taste. 

Larger  holes  are  easily  deburred  by  use  of  an 
automotive  valve-seat  reamer.  These  come  with 
four,  five,  and  six  blades  and  cost  from  $2.00 
up.  No  changes  are  needed  in  this  tool,  and  those 
with  a  large  number  of  blades,  such  as  six,  are 
preferable  to  the  four-bladed  type.  When  only 
steel  is  to  be  used,  an  abrasive  valve  seater,  which 
is  merely  a  conical  grindstone  with  a  large 
included  angle,  such  as  105  degrees,  is  very  effec- 
tive. This  cannot  be  used  with  soft  metals,  such 
as  aluminum,  as  the  abrasive  will  plug  up  after 
deburring  onlj'  a  few  holes.

STAND-BY    SWITCH    FOR   THE    H0-129X 

DURING  week  ends  it  was  desired  to  leave  my 
recently  acquired  HQ-129X  on  stand-by  for 
long  periods  and  this  made  desirable  the  removal 
of  B  +  from  all  tubes  of  the  receiver.  This  meant 
the  addition  of  a  switch  in  the  ground  side  of  the 
plate-supply  circuit,  but  the  thought  of  any  panel 
drilling  that  might  adversely  affect  the  resale 


value  of  the  receiver  was  deemed  objectionable. 
The  solution  arrived  at  was  to  remove  the 
existing  5000-ohm  sensitivity  potentiometer  and 
replace  it  with  a  type  having  an  on-off  switch 
mounted  on  the  rear  cover.  The  switch  is,  of 
course,  used  to  break  the  negative  plate-supply 
lead.  With  the  revision,  the  receiver  is  turned 
on  or  off  with  the  sensitivity  control,  the  front 
panel  remains  intact,  and  the  "relay  control" 
function  of  the  original  stand-by  switch  (Se  of 
the  circuit  for  the  HQ-129X)  is  not  impaired.

MORE  ABOUT  THE  NOVEL  VENTI- 
LATING SYSTEM  FOR  MOBILE  UNITS 

WHEN  using  the  ventilating  suggested  by 
W9JX  in  QST  for  June,  1955,  it  is  advisable 
to  avoid  connection  to  the  vacuum  line  from  the 
intake  system.  Otherwise,  you  may  run  into 
valve  trouble  caused  by  an  improper  air-gas 
mixture  from  the  carburetor.

PERIODIC  INSPECTION  FOR 
COPPERCLAD  WIRE  ANTENNAS 

HERE  is  a  tip,  learned  from  bitter  experience, 
that  should  benefit  any  of  the  gang  who  use 
surplus  copperclad  wire  for  their  sky  hooks. 
Antennas  made  from  this  material  require  in- 
spection once  a  year  or  so  if  deterioration  in 
advance  of  actual  breakdown  is  to  be  detected. 
In  my  own  case,  I  had  a  nifty  340-footer  about 
50  feet  high  that  was  made  with  surplus  aircraft- 
trail  wire  obtained  from  a  bargain  3000-foot  reel. 
After  about  four  years  of  service  —  without  in- 
spection —  trouble  started.  Wherever  the  wire 
came  in  contact  with  stand-offs,  strain  insulators 
or  other  supports,  and  at  points  where  bends 
were  necessary,  the  copper  coating  had  worn 
through  and  rust  had  eaten  into  the  core,  thus 
creating  about  half  a  dozen  high-resistance  joints 
that  finally  broke  down.

SCORING  ALUMINUM  WITH  A 
GLASS  CUTTER 

AN  ordinary  dime-store  glass  cutter  (disk  roller 
-  type)  makes  an  excellent  tool  for  cutting 
aluminum  sheet.  Just  score  each  side  of  the 
sheet  and  then  flex  the  aluminum  until  it  parts 
at  the  score.  If  the  sheet  being  worked  with  is 
fairly  large,  it  pays  to  clamp  the  metal  along 
the  score  lines  by  one  means  or  another.

YOU'RE  COVERED 

705  Ninth  Avenue 
Brookings,  So.  Dak. 
Editor,  QST: 

I  have  read  with  interest  your  article  "  Lightning  Protec- 
tion for  the  Transmitting  Antenna  (July  QST)."  Inasmuch 
as  I  am  in  accord  with  the  article  and  endorse  all  the  ideas 
involved  there  is  one  thing  that  should  be  straightened  out. 
There  is  no  condition  in  any  of  the  fire  forms  used  for  in- 
surance purposes  on  a  private  dwelling  that  would  invali- 
date an  insurance  policy  insuring  such  private  dwelling 
whether  that  antenna  is  a  TV  antenna  or  a  5-element  beam 
for  10  meters. 

There  are  too  many  people  now  who  believe  that  in- 
surance is  a  necessary  evil  and  one  of  those  articles  that 
have  to  be  paid  for  because  of  a  loan  on  their  dwelling.  If 
you  can  find  any  of  the  so-called  fine  print  excluding  cov- 
erage in  a  private  dwelling  fire  form  because  of  an  improp- 
erly-installed antenna,  please  send  it  out  to  this  ham.  It 
would  be  very  interesting,  I  can  assure  you. 

For  further  information  I  would  suggest  that  you  contact 
two  of  the  best  insurance  companies  in  the  world  for  further 
information,  The  Hartford  Fire  and  The  Travelers,  both 
of  whom  we  represent.  —  Robert  T.  Bales,  W6  UDI

fine  print  invalidates  a  policy  specifically  because  of  an  an- 
tenna installation.)

Many  thanks  to  W0PDN  for  his  understanding  letter  in 
the  May  issue.  He  is  correct  in  his  assumption  that  air  mail 
stamps  for  every  QSO  is  completely  out  for  most  Ethiopians. 
Especially  those  in  the  Armed  Forces  have  an  allowance  not 
at  all  comparable  with  that  of  the  U.  S.  Forces,  and  the 
civilian  standard  could  be  regarded  much  in  the  same  way. 

One  of  the  most  active  ham  stations  is  that  of  the  Im- 
perial Ethiopian  Air  Force,  ET3Q  and  ET3R,  which  is 
worked  entirely  by  A.  F.  personnel.  I  will  admit  that  the 
promised  QSLs  from  here,  in  many  cases,  have  not  been  sent 
in  the  past.  I  enclose  a  QSL  card  from  ET3Q  which  has  been 
released  for  use  only  some  weeks  ago  by  His  Imperial 
Majesty.  I  now  hope  the  QSL  cards  from  here  will  drop 
in  more  regularly  at  the  stations  of  U.  S.  hams.  Please,  don't 
ask  for  air  mail.

P.  O.  Box  3093 
Rochester  14,  N.  Y. 
Editor,  QST: 

.  .  .  Recently  I  came  back  to  75  because  a  fellow  ham 
friend  of  mine  vacationing  in  Canada  asked  me  to  keep 
morning  skeds  with  him.  .  .  . 

I  listened  around  and  I  found  new  voices  and  recognized 
some  old  ones.  But  what  surprised  me  very  much  was  a  new 
mode  of  calling  which  must  be  peculiar  to  75  because  I 
have  not  heard  that  stuff  on  other  bands.  For  example: 
"Calling  CQ  class  A,"  and  "Calling  CQ  no  lids."  Then  I 
heard  guys  talking  about  guys  and  mentioning  names  and 
call  letters  openly.  Intentional  QRM  galore.  Traffic  nets  in 
bunches,  where  real  traffic  just  is  not  it.  I  asked  one  old 
tinier  "How?"  and  he  said  "Oh,  that's  been  going  on  for 


years,  where' ve  ya  been?"  In  that  period  of  time  I  was  ab- 
sent from  75  I  think  I've  come  back  a  couple  of  times  before, 
but  did  not  stay  as  long  as  this  time.  I  listened  some  more 
and  I  got  disgusted  with  it. 

My  opinion  of  that  particular  brand  of  ham  radio  is  that 
it  is  not  genuine  ham  radio  at  all;  one  of  the  guys  I  heard  is 
suffering  from  such  an  inferiority  complex  that  he  is  making 
his  friends  and  others  who  bother  with  it,  act  like  foolish 
kids.  As  soon  as  my  friend  returns  from  his  vacation,  I'll  go 
back  to  DX-c.w.  for  that  band,  75,  is  for  the  birds  as  far  as 
I'm  concerned.

Editor,  QST: 

I  am  secretary  of  the  Reading  Radio  Club,  members  of 
which  have  participated  in  many  of  the  activities  mentioned 
in  your  July  editorial,  "Public  Relations."  .  .  .  Our  latest 
effort  was  the  Powder  Puff  Derby;  we  were  asked  to  relay 
between  the  Reading  Airport  and  the  terminus  of  the  Derby, 
Springfield,  Mass.  .  .  .  Most  of  the  boys  on  75  are  swell 
fellows;  many  of  them  cooperated  with  us  100%;  however, 
two  or  three  gave  us  a  rough  time.  .  .  . 

We  fully  realize  that  all  amateur  frequencies  are  open  to 
everyone,  and  we  also  realize  that  the  public  in  general  re- 
sents being  pushed  around.  .  .  .  But  when  we  politely  re- 
quested W3  —  to  keep  this  particular  channel  clear  he 
resented  the  request,  called  us  Space  Cadets,  and  flatly  re- 
fused to  stay  off  the  frequency.  .  .  .  Several  other  stations 

also  resented  our  request.  For  instance,  W2 ;  every  time 

we  would  sign  he'd  come  on  the  frequency  calling  another 
station.  We  doubt  that  he  actually  was  in  contact  with 
anyone  because  of  the  fact  that  whoever  he  might  have 
been  talking  to  surely  could  not  have  stopped  transmitting 
at  the  exact  time  we  did,  so  many  times  in  succession.  This 
same  W2 would  hook  up  with  a  powerful  station  else- 
where in  the  band,  tell  him  he  had  QRM  and  that  he  should 
change  frequency  and  move  down  on  the  frequency  we  were 
using.  Then  both  would  carry  on  a  QSO. 

What  would  the  Old  Man  think  about  such  tactics?  What 
would  happen  in  an  emergency?  Why  can't  we  look  at  it  in 
this  way  and  realize  that  here  are  a  bunch  of  hams  doing 
something  to  publicize  ham  radio,  giving  of  their  time, 
gratis,  trying  to  live  up  to  the  concept  of  your  editorial,  and 
give  us  a  band  instead  of  a  fist. 

Before  I  close,  we  of  the  Reading  Radio  Club  wish  to 
thank  again  the  fellows  who  cooperated  with  us  in  this 
venture.

EXTRA  CLASS  PRIVILEGES 

446  N.  W.  8th  St. 
Homestead,  Fla. 
Editor,  QST: 

I've  been  thinking  over  the  situation  of  the  Amateur 
Extra  Class  license  and  have  come  up  with  an  idea  which 
might  provide  a  little  incentive  for  getting  a  ticket. 

Some  of  the  little  used  portions  of  the  ham  bands  could 
be  set  aside  exclusively  for  Amateur  Extra  ops.  For  ex- 
ample, 14,300-14,350  kc.  could  be  used. 

Another  thing,  which  would  probably  bring  a  lot  of 
argument,  would  be  to  allow  only  Amateur  Extra  operators 
to  employ  such  advanced  techniques  as  RTTY  and  s.s.b. 

Let's  hear  from  the  fellows  on  this  subject. 

(Incidentally,  I'm  not  Amateur  Extra,  but  General  Class, 
although  I  do  intend  to  get  it  just  as  soon  as  I  have  had  my 
ticket  long  enough.)

Amateurs  in  Operation  Alert,  1955 

A  Summary  of  Reports  of  Amateur/ RACES  Participation  in  FCDA's 
Nation-wide  Civil  Defense  Test 

BY  GEORGE  HART.  WINJM 


ON  June  15th,  at  1600  GMT,  Civil  Defense  or- 
ganizations throughout  the  country  swung 
into  action  to  put  to  the  test  our  nation- 
wide c.d.  establishment.  The  entire  nation  was 
subjected  to  a  thorough  simulated  plastering  by 
nuclear  weapons,  from  twenty  kiloton  (Ix)  to  five 
megaton  (250x)  in  size.  As  far  as  nuclear  attack 
is  concerned,  FCDA  was  assuming  the  worst,  ex- 
cept that  all  concerned  were  notified  in  advance. 
Under  date  of  June  1st,  ARRL  notified  its 
entire  contingent  of  Emergency  Coordinators 
(some  1700  of  them)  of  the  coming  exercise,  urg- 
ing them  to  activate  their  RACES  or  pending 
RACES  plans  in  this  exercise.  Instead  of  re- 
questing them  to  fin  out  another  questionnaire 
form,  we  this  time  asked  for  a  simple  narrative 
of  activities  in  their  area.  This  report  is  a  sum- 
mary of  such  narratives,  condensed  or  reduced  as 
necessary  to  fit  into  available  QST  space.  If  the 
report  of  activities  in  your  area  is  not,  perchance, 
included,  it  is  because  up  to  copy  time  nothing 
was  received  indicating  that  you  were  active. 

Arizona 

In  Tucson,  the  civil  defense  council  dispersed 
to  a  fringe  area  (Marana  Air  Base)  and  depended 
on  Al  Steinbrecher,  W7LVR  (SCM),  to  maintain

contact  with  elements  not  present  at  this  control 
center.  Al  did  a  good  job  and  was  relied  on 
heavily. 

California 

The  Lennox  District  of  the  Los  Angeles  County 
Disaster-Civil  Defense  Authority  (RACES)  op- 
erated as  the  Lennox  Disaster-Civil  Defense  Net 
(AREC)  extensively.  Prepared  messages  were 
distributed  by  the  ten-meter  mobile  stations, 
who  reported  the  locations  of  messages  left  and 
the  party  to  see  the  NCS.  This  was  posted  on  a 
map.  Then  2-meter  stations  were  dispatched  to 
pick  up  the  messages  and  transmit  them  to  the 
2-meter  NCS,  where  they  were  answered  and  re- 
layed back  to  the  originating  station.  RACES 
tactical  calls  were  used  by  all  authorized  stations. 
RO  and  EC  W6NHP  states  that  there  are  now 
52  members  of  the  Lennox  C.D.  Net  with  RACES 
certifications.  Forty-eight  amateurs  participated. 

British  Columbia 
SEC  VE7DH  summarizes  the  operation  in 
British  Columbia.  Nineteen  stations  participated, 
with  sixteen  monitoring  and  ready  to  help.  A  total 
of  322  messages  were  handled,  including  87  by 
VE7QC,  118  by  VE7KL  (NCS)  and  47  by 
VE7N0.  VE7ASR  acted  as  mobile  net  control. 
VE7AHJ  monitored  Alaska  alert  KL7TI.  Fre- 
quencies used  were  3505,  3740,  3755,  3995  and 
147.33  Mc.  VE7DH  says  only  one  thing  bothers 
him:  how  did  controls  keep  on  operating  at  ground 
zero  after  a  fifty  kiloton  bomb  exploded? 

Colorado 
W0TVB,  EC  for  Mutual  Aid  Area  No.  10  in 
Northwestern  Colorado,  reports  operation  from 
the  Moffat  County  Courthouse  in  Craig,  using 
his  transmitting  equipment  and  call.  Activity 
commenced  at  0900  MST,  with  total  operation  of 
15  hours  before  the  test  terminated.  Contact  was 
maintained  sporadically  with  state  control  at 
Denver,  handling  nine  outgoing  and  ten  in- 
coming messages.  W0SJJ  was  active  from  Steam- 
boat Springs,  Colo.  All  amateurs  taking  part 
were  AREC  members.  Operation  was  completely 
on  auxiliary  power  for  one  hour.  The  EC  gives 
full  credit  to  members  of  the  Yampa  Valley  Radio 
Club,  all  AREC  members,  for  all  equipment  and 
improvements,  including  the  installation  of  the 
civil  defense  director  himself.  He  says,  "We  are 
proud  of  the  accomplishments  we  have  made  — 
so  far." 

Connecticut 

In  Manchester,  18  operators  were  asked  for  but 
24  signed  up  to  keep  the  control  station  open  for

A  partial  shot  of  Connecticut's  Area  I  RACES  Con- 
trol Station,  located  at  the  State  Police  Barracks  in 
Ridgefield.  At  this  location,  six  nets  were  manned  by 
sixteen  operators  working  in  two  shifts,  six  hours  on  and 
six  hours  off,  during  Operation  Alert. 


the  full  twenty-six  hour  period  of  the  drill.  Traf- 
fic was  handled  both  for  the  local  area  and  re- 
layed for  stations  not  in  good  contact  with  Area 
Control  in  Rocky  Hill.  Civil  defense  officials  were 
greatly  pleased  with  the  amateurs'  response. 

Connecticut's  Area  I  RACES  organization, 
consisting  of  22  towTis  in  Fairfield  County,  was 
active  to  the  extent  of  180  operators  manning 
65  stations  throughout  the  26  hours  of  the  test. 
The  message  total  was  2700.  This  is  a  considerable 
increase  over  the  2156  total  for  1954,  indicating 
both  the  increased  efficiency  and  expansion  of 
the  organization.  Traffic  was  handled  at  the  rate 
of  104-per-hour  or  1.7-per-minute  throughout  the 
entire  test  period.  Area  I  Radio  Officer  WlDBM 
spent  most  of  the  time  traveling  from  one  local 
control  to  another  to  visit,  inspect  and  take  pic- 
tures. Many  of  the  control  centers  had  a  full  staff 
of  service  chiefs  on  dut}',  while  others  had  only 
skeleton  crews.  WlDBM  opines  that  although 
the  performance  in  Area  I  was  outstanding,  it 
would  be  inadequate  in  the  event  of  a  real  bomb- 
ing, the  2700  messages  being  but  a  drop  in  the 
bucket  compared  with  the  actual  need. 

Dela  ware 

For  the  first  time,  the  Communications  Divi- 
sion of  Delaware  Civil  Defense  functioned  as  ex- 
pected and  desired,  reports  W3DB,  Deputy 
Chief  of  Communications.  RACES  operated  on 
3507.5  kc.  and  3580,  with  local  work  on  10,  6 
and  2  meters.  The  State  control  station  at  Dela- 
ware City,  New  Castle  County  control  at  New 
Castle,  Kent  County  control  at  Dover  and 
Sussex  Count}^  control  at  Georgetown  were  all 
alerted  and  ready  to  go  at  the  appointed  time. 
The  state  control  station  alone  handled  more 
than  250  messages  during  the  test.  Over  fifty 
amateurs  took  part. 

Illinois 

From  DeKalb,  111.,  we  have  a  clipping  quoting 
the  DeKalb  c.d.  director  as  sajdng  that  "the 
mobile  communications  sj'stem  set  u>  by  the 
Kishwaukee  Radio  Club  made  an  excellent  show- 
ing." Mobiles  were  organized  to  patrol  various 
sections  of  the  city,  reporting  conditions  to  a  cen- 
tral location.  W9WTF  is  the  spark-plug. 

Indiana 

The  Evansville  gang  was  active.  A  rig  on  147.3 
Mc.  f.m.  was  used  at  the  control  center.  Dress 
Memorial  Airport,  to  control  a  similar  unit  lo- 
cated in  the  "devastated"  area.  A  unit  on  29.6 
Mc.  was  used  to  handle  traffic  to  20  mobiles  be- 


longing to  RACES  members.  Ten-meter  set-ups 
were  also  located  at  the  National  Guard  Armory 
and  the  local  taxicab  dispatcher's  office  so  that 
medical  units  and  taxicabs  could  be  dispatched 
as  needed  from  the  control  point  within  the 
affected  area.  St  ate- wide  communication  was 
conducted  on  3910  kc. 

Kentucky 

SEC  W4CDA  reports  that  Kentucky  civil  de- 
fense was  provided  with  c.w.-  and  'phone-net 
communications  for  their  five  Mobile  Support 
Group  cities.  W4CDA  ojjerated  the  c.w.  net  on 
3600  kc,  using  equipment  set  up  bv  State  Radio 
Oflicer  W4MGT.  W4TFK,  Frankfort  EC,  op- 
erated his  own  'phone  station.  Each  station 
handled  approximately  30  test  messages. 

W4JSH,  EC  for  Lexington,  reported  on  Op- 
eration Alert  for  the  Fifth  Mobile  Support 
Group.  This  group  handled  65  messages,  partici- 
pation by  nineteen  stations  on  3600,  3945  and 
3960  kc.  Operating  time  w^as  from  1815  to  2215 
EST.  Representation  was  thus  provided  for  seven 
of  the  25  counties  making  up  the  Fifth  Mobile 
Support  Group. 

Louisiana 

SEC  W5IUG  reports  that  eight  ECs  reported 
participation,  plus  the  SEC  and  SCM,  and  that 
69  amateurs  took  part  throughout  the  state. 

Maryland 

In  Baltimore,  165  amateurs  participated.  Radio 
Officer  W3NNX  and  his  assistant,  W3YYB, 
quickly  alerted  and  activated  all  stations  with 
such  good  effect  that  Col.  Milani,  c.d.  director 
for  the  city,  said,  "This  group,  following  amateur 
tradition,  fulfilling  a  most  important  function, 
seriousl)',  calmly  and  expeditiously  carried  out 
their  duties  in  a  professional  manner." 

St.  Marj-'s  County  amateurs  also  report  par- 
ticipation. W3BUD  moved  his  75-meter  station 
to  county  c.d.  headquarters  at  Leonardtown, 
maintaining  a  circuit  to  W3CBW  at  state  c.d. 
headquarters  during  the  alert.  In  addition,  a 
county  net  of  six  stations  on  another  frequency

Young  Ladies'  Radio  League  First 
In  tern  a  tion  al  Con  ven  tion 

Judging  from  reports  received,  the  YLs  who  attended  the 
Young  Ladies'  Radio  League's  First  International  Conven- 
tion will  long  remember  the  precedent-setting  affair.  The 
convention  is  reported  here  in  considerable  detail  so  that 
those  YLs  who  were  not  able  to  be  there  in  person  may  catch 
the  spirit  of  the  affair.  Thanks  are  due  to  Mary  Brandvig, 
W6LB0,  Convention  Publicity  Co-Chairman,  for  furnishing 
most  of  the  information. 

On  Friday  afternoon,  June  24th,  the  three-room  suite 
engaged  by  the  YLRL  at  the  Miramar  Hotel  in  Santa 
Monica,  Calif.,  bulged  with  registrants.  The  club  photo- 
graph albums  and  scrapbooks  were  on  display  and  continu- 
uous  rag-chewing  was  in  order. 

At  the  business  meeting  Saturday  morning,  Mildred 
Griffin,  W6PJU,  past-president  of  the  Los  Angeles  YLRC, 
presided  as  official  hostess.  Each  YL  was  given  a  bracelet 
of  copper  coiled  links  with  YLRL  insignia,  on  which  Martha 
Edwards,  W6QYL,  and  her  committee  —  K6s  EJE  and 
GMX,  and  W6s  T>Xl,  PJU,  and  QGX  —  had  worked  since 
fall.  Souvenir  program  booklets  in  the  official  club  colors  — ■ 
silver  and  blue  —  were  distributed. 

General  Convention  Chairman  Maxine  Willis,  W6UHA, 
opened  the  meeting  with  a  welcome  and  introduction  of 

*  YL  Editor,  QST.  Please  send  all  news  notes  to 
WlQON's  home  address:  318  Fisher  St.,  Walpole,  Mass. 

*  All  officers  were  in  office  at  the  time  of  the  convention, 
which  occurred  only  a  few  days  before  a  new  term  began 
(July  1st).  A  new  slate  of  officers  now  rules. 


YLs  from  the  following  areas:  W3,  5,  6,  7,  8,  and  0,  KZ5 
and  KL7. 

The  importance  of  communication  in  today's  world  was 
stressed  in  an  address  by  the  Mayor  of  Santa  Monica,  the 
Honorable  Ben  Benard. 

Business  Meeting 

President  of  the  YLRL,  Vada  Letcher,  W6CEE,*  con- 
ducted a  brief  business  meeting,  which  included  the  reading 
of  reports  from  her  officers.  The  report  of  Publicity  Chair- 
man, Gloria  Matuska,  W9YBC,  was  read  in  absentia  by 
W6LBO.  W3PVH,  Betty  Frederick,  delegate  from  W3UUG, 
Miriam  Blackburn,  Secy.-Treas.,  read  the  financial  report, 
which  revealed  a  treasury  balance  on  June  1,  1955,  of 
$964.35.  Vice-President  Gilda  Shoblo,  W6KER,  reported 
on  contest  activity  during  the  year  and  requested  that 
suggestions  regarding  the  conducting  of  contests  and  activ- 
ities be  forwarded  to  the  new  Vice-President,  W9YBC. 
W6CEE  thanked  each  member  and  officer  for  the  coopera- 
tion extended  to  her  and  expressed  the  hope  that  the  new 
President,  Cris  Bowlin,  W9L0Y,  and  all  of  the  other  officers 
would  receive  the  same  consideration. 

The  First  and  Second  Vice-Presidents  of  the  YLRL,  Carol 
Witte,  W6WSV,  and  Enid  Aldwell,  W6UXF,  spoke  of  the 
history  and  development  of  the  organization,  from  its  begin- 
nings in  1939  to  the  present  day.  Greetings  were  given  by 
W5RZJ,  W6NZP,  W6MWU,  and  WIQON  (the  last  a 
written  message  read  by  W6KER). 

Honorary  membership  for  life  in  the  YLRL  was  conferred 
on  Ethel  Smith,  W3MSU,  YLRL  founder  and  first  Presi- 
dent. An  acrostic,  composed  and  hand-worked  by  Vi 
Grossman,  W2JZX,  was  to  be  sent  to  Ethel. 

The  YLRL  song,  with  words  by  Dorothy  Willett, 
W8UDA,  was  sung  in  unison  and  led  by  Betty  Wilson, 
W6REF.  Betty  also  sang  a  new  YLRL  Convention  song, 
with  words  and  music  by  W6UHA. 

Three  convention  tickets  were  awarded  —  one  to  W5RZJ, 
who  won  the  Membership  Contest,  one  to  W6WSV,  who 
was  the  member  with  the  highest  indiWdual  score  in  the 
Los  Angeles  YLRC,  the  club  which  had  the  greatest  number 
of  new  members.  The  third  ticket  was  awarded  to  KZ5DG, 
Grace  Dunlap,  as  a  representative  of  the  area  which  had 
the  greatest  percentage  of  membership  increase  during  the 
past  year. 

Five  special  gilt-trimmed  YLRL  certificates  were  awarded 
to  W4JCR,  Anita  Bien,  for  outstanding  work  in  revising 
the  club  Constitution  and  By-laws  (see  W4  YL  photo 
elsewhere  in  this  department) ;  to  W6NAZ,  Lenore  Conn, 
for  her  excellent  work  in  editing  and  publishing  the  YLRL

QST  for 


Directory;  to  W6UHA  for  her  efficient  organization  of  the 
convention;  and  to  W6LB0  and  W9YBC  for  their  nation- 
wide campaign  of  publicity  for  the  YLRL. 

Reception 

After  the  business  meeting,  the  group  adjourned  to  the 
Palm  Room  of  the  hotel,  where  anthurium,  orchids  and  ti 
leaves,  flown  from  Hawaii  by  WCSHR's  OM,  provided  a 
tropical  background  for  the  miniature  ceramic  ham  shacks 
made  by  W6MFP,  Agnes  Langevin,  Decorations  Chairman. 
Jayne  Dynes,  K6GMX,  had  assembled  and  soldered  a 
variety  of  antenna  arrays  which  stood  over  the  little  ham 
shacks.  One  of  the  little  shacks,  with  a  three  element  20 
meter  beam,  duplicate  of  WGUHA's  station  beam,  was 
wired  for  a  lamp  as  a  gift  to  Maxine  from  the  Los  Angeles 
YLRC. 

Presentation  of  leis  from  members  of  the  Honolulu  YL 
club,  flown  from  that  city  by  arrangement  of  KH6AFN 
and  W6SHR,  was  done  in  the  Hawaiian  manner  with  88s 
from  W6KER  to  W6CEE,  W6UHA,  and  to  each  new 
district  chairman  or  her  proxy. 

Fashions  from  a  near-by  clothing  salon  were  modeled. 
While  Martha  Edwards,  W6QYL,  modeled  the  wedding 
gown  she  made  of  the  silk  brocade  her  recent  bridegroom, 
W6RDQ,  brought  from  Japan,  Lenore  Conn,  W6NAZ, 
narrated  the  story  of  their  courtsliip  and  wedding. 

Elizabeth  Zandonini,  W3CDQ,  and  Evelyn  Scott, 
W6NZP,  recounted  meetings  with  overseas  YLs  during 
recent  travels  abroad.  KL7RN  and  KZ5DG  spoke  on  YL 
activities  in  Alaska  and  in  the  Canal  Zone. 

Banquet 

Hundreds  of  Hawaiian  orchids,  tall  green  tapers,  and 
giner  leis  decorated  the  tables  for  the  evening  banquet. 
W6UHA  was  mistress  of  ceremonies.  Each  YL  bamjuet 
guest  was  presented  with  a  certificate  designed  liy  W6KER 
and  W6MFP,  making  the  recipient  a  charter  member  of  all 
future  YLRL  Conventions. 

A  talk  on  the  early  days  of  amateur  radio  by  John 
Reinartz,  K6BJ,  was  one  of  the  features  of  the  evening. 
Mr.  Reinartz  declared  that  he  was  especially  happy  to 
speak  on  the  occasion,  for  after  thirty-five  years  of  married 
life,  his  wife  had  recently  become  Novice  KN6iMJH. 

Enid  Aldwell,  W6UXF,  and  her  Bavarian  Dance  Group, 
entertained  with  colorful  and  authentic  dances  of  Bavaria. 

Bernard  Linden,  Engineer-in-Charge  of  the  Los  Angeles 
area  office  of  the  FCC,  brought  a  message  of  congratulations 
and  clippings  of  early-day  YLs  from  his  personal  scrapbook. 

Although  many  YLs  had  to  leave  after  the  main  conven- 
tion events  on  Saturday,  a  number  remained  in  tlie  area  and 
visited  the  homes  of  Los  Angeles  YLs  and  attended  a  mobile 
caravan  to  CBS-TV  City  on  Monday,  arranged  by  Mary 
Kay,  W6JMC. 

And  thus  the  first  international  convention  of  the  YLRL 
came  to  an  end. 

The  convention  is  significant  not  only  of  the  progress 
of  the  YLRL  —  it  reflects  the  increase  in  numbers  and 
activity  of  YLs  in  general.  A  few  years  ago  a  convention  of 
this  sort  could  not  have  occurred.  Now  the  question  is  when 
and  where  is  the  ne.\t  one  going  to  be?  With  the  example  of 
hard  work  and  enthusiasm  displayed  by  the  YLs  of  the 
Los  .\ngeles  YLRC,  the  way  points  to  bigger  and  better  YL 
get-togethers  in  the  future.

TVI  IN  GREAT  BRITAIN 

The  Engineering  Department  of  the  GPO 
(Government  Post  Office)  of  Great  Britain  has 
released  recent  figures  on  TVI  and  BCI  in  that 
country.  The  GPO  is  the  British  equivalent 
of  our  FCC.  Figures  shown  were  extracted  mainly 
from  an  editorial  appearing  in  the  R.S.G.B. 
Bulletin  and  partly  from  The  Short  Wave  Maga- 
zine, British  amateur  publications. 

Interference  Caused  by  Transmitters 
Amateur  Others 

BCI  — 125  BCI  — 142 

TVI  — 303  TVI  — 476 

Other  TVI  offenders  were : 
8956  se\ving  machines 
7056  commutator-type  motors 
6954  hair  dryers 
1064  TV  receiver  local  oscillators 

The  GPO  classified  21,877  TVI  cases  under 
the  all-embracing  category  "unknown."  Also, 
G805  instances  of  BCI  were  recorded  as  caused  by 
TV  receiver  time-base  circuits. 

INTERFERENCE  COMMITTEE  DIRECTORY 

The  Southern  California  Electronics  Inter- 
ference Committee  publishes  "Cooperative  Inter- 
ference Committee  Directory."  This  pamphlet, 
compiled  under  the  supervision  of  Ray  E.  Myers, 
W6MLZ,  contains  valuable  information  for  TVI 
committee  members  as  well  as  other  groups. 

To  be  found  in  this  booklet  are  three  lists.  The 
first  is  an  index  of  those  participating  in  the 
program.  It  gives  addresses  and  also  home  and 
office  telephone  numbers  where  authorization  to 
do  so  was  received.  The  second  shows  the  geo- 
graphic location  of  the  participants.  The  last  is  a 
compilation  of  the  various  interests  of  those 
taking  part. 

Also  included  is  an  investigation  report  form. 
Its  purpose  is  to  show  sufficient  data  so  as  to 
indicate  quickly  causes  and  corrective  measures 
on  future  reports  called  to  the  committee's 
attention. 

LATEST  TVI  COMMITTEE  LIST 

The  following  is  the  latest  FCC  roster  of  TVI 
committees.  It  is  interesting  to  note  that  since 
March  1,  1954,  95  new  committees  have  been 
organized,  bringing  the  total  to  437.  These  com- 
mittees now  serve  412  cities  as  compared  to  328 
as  of  March  1,  1954.  Such  progress  is  indeed 
gratifying  and  statistics  indicate  that  much

Military-to- Amateur  Test 

Operating  on  miUtary  frequencies,  AIR,  NSS 
and  WAR  worked  amateurs  on  the  80-,  75-, 
40-,  and  20-meter  bands.  The  three  militarj'^ 
stations  made  a  total  of  564  QSOs  with  amateurs 
during  the  six-hour  test.  Special  Armed  Forces 
Day  QSL  cards  have  been  mailed  to  all  stations 
worked.  It  was  possible  to  receive  three  cards  by 
working  all  three  stations. 

Radioteletypewriter  Receiving  Competition 

There  were  fiftj'-two  participants  in  radio- 
teletype  waiter  competition  this  j-ear  and  27  of 
this  number  made  perfect  copy.  A  letter  of 
acknowledgment  has  been  mailed  to  each  par- 
ticipant. All  suggestions  received  for  improving 
and  creating  interest  in  this  phase  of  Armed 
Forces  Day  \\dll  be  taken  into  consideration 
during  the  forthcoming  j-ear. 

The  Army,  Navy  and  Air  Force  look  forward

September  1955 


55 


June  V.H.F.  Party  Summary 

Scores  and  Activity  Set  Many  New  Records 


PICK  any  category  in  which  v.h.f.  contests 
can  be  compared,  and  the  chances  are  good 
that  the  June  V.H.F.  Party  of  1955  will 
rate  a  record.  The  festivities  of  June  11th  and 
12th  resulted  in  a  new  high  in  participation,  with 
455  valid  entries,  compared  to  a  previous  record 
of  370  for  any  of  the  spring-fall  contests.  There 
were  many  more  portable  and  multiple-operator 
stations,  as  clubs  more  and  more  make  use  of 
the  June  Party  as  a  test  of  Field  Day  facilities. 
The  advent  of  Technician  licensees  on  50  Mc. 
brought  a  new  surge  of  life  to  that  band,  and  the 
number  of  operators  using  6  was  up  60  per  cent 
over  last  June.  More  ARRL  sections  (55)  were 
heard  from  than  in  any  previous  v.h.f.  activity, 
and  the  scores  of  both  individual  operators  and 
groups  broke  all  records. 

The  highest  total  ever  posted  in  a  v.h.f.  contest 
was  turned  in  by  the  Waltham  Amateur  Radio 
Association,  WlMHL/1.  Of)erating  from  Pack 
Monadnock  Mountain,  near  Peterboro,  N.  H.,  as 
they  have  in  every  party  for  years,  the  Watch 
City  club  made  97  contacts  on  50  Mc,  243  on 
144  Mc,  15  on  220  Mc,  and  10  on  420  Mc. 
Their  section  multiplier,  a  staggering  43,  netted 
them  16,770  points.  Taking  their  single-band 
totals,  we  find  them  leading  the  country  on  50, 
220  and  420  Mc.  The  2-meter  job  of  WIPYM, 
who  ran  the  2-meter  position  throughout  the 
contest,  was  second  in  the  country  for  2-meter 
work.  His  3157  points  (figured  on  the  basis  of 
2-meter  operation  only)  was  exceeded  in  that 
category  only  by  W3IBH. 

The  top  single-operator  score  was  made  by 
W2FBZ,  Montclair,  N.  J.  Lee  won  the  Northern 
New  Jersey  Section  Award  again  with  233  con- 
tacts on  4  bands.  Her  section  multiplier  of  34 
brought  this  to  8534  points,  another  record. 
Right  behind  Lee  in  the  home-station  category 
was  WlRFU,  Wilbraham,  Mass.,  with  211  con- 


tacts on  50,  144  and  220  Mc,  for  7548  points. 
W3KKN,  Willow  Grove,  Pa.,  made  the  most 
contacts  of  any  single-operator  station,  251  on 
6  and  2  meters,  for  5522  points.  His  neighbor, 
W3IBH,  Philadelphia,  worked  220  stations  in 
15  ARRL  sectioni  for  3300  points,  the  country's 
high  one-band  effort. 

The  San  Bernardino  Microwave  Society, 
W6VIX/6,  hung  up  three  marks  for  groups  to 
shoot  at  in  future  contests.  Operating  from 
Sierra  Peak,  near  Corona,  Calif.,  they  made  an 
even  400  contacts,  306  of  which  were  on  144 
Mc,  for  a  new  Western  record  of  6165  points. 
They  used  50,  144,  220,  420,  2400  and  3300 
Mc,  but  they  say  that  this  is  only  the  beginning. 
Their  u.h.f.  and  microwave  gear  is  going  to  be 
much  more  effective  for  the  September  Party. 
Congratulations  to  operators  W6VIX,  W6JMY, 
K6GMV,  and  K6HXM  for  demonstrating  that 
a  West  Coast  station  can  be  right  up  among  the 
leaders,  despite  the  handicap  of  geographically 
immense  ARRL  sections. 

Dozens  of  other  portable  stations  contributed 
mightily  to  the  fun.  K2CMB/2,  Paterson,  N.  J., 
posted  the  next  to  the  highest  single-operator 
score,  7714  points,  on  50,  144,  and  220  Mc.  with 
his  trailer  station.  W3KX/3,  the  Electric  City 
Radio  Club,  maintained  their  customary  leader- 
ship in  the  Eastern  Pennsylvania  Section  with 
8103  points  made  on  four  bands.  WlUIZ/1, 
Mt.  Equinox,  Vermont,  put  that  hard-to-get 
section  within  the  reach  of  many,  working  50, 
144,  220,  420,  and  3300  Mc.  His  sole  contact  on 
3300  was  with  WlIUN/1,  who  used  gear  built 
in  1947,  with  which  he  made  what  may  have 
been  the  first  amateur  contacts  on  that  band. 

Scores  of  Technicians,  using  50  Mc.  for  the 
first  time  in  a  contest,  kept  that  band  jumping 
with  activity.  Oddly  enough,  no  Technician 
qualified  for  an  award,  however,  as  there  were  no 


Members  of  the  San  Bernar- 
dino Microwave  Society  oper- 
ating W6VIX/6  in  the  June 
V.H.F.  Party  made  an  even  400 
contacts  on  ,S0,  144,  220,  420, 
2400  and  3300  Mc.  K6GMV,  left, 
runs  the  420-Mc.  gear,  while 
K6HXM  supervises  the  2400-Mc. 
tests  being  made  by  W6JMY. 
The  W6VIX/6  score,  6165  points, 
was  an  all-time  high  for  a  station 
outside  the  small-section  East, 
and  their  contact  total  was  the 
highest  in  v.h.f.  contest  history. 


QST  for 


instances  where  the  necessary  three  entrants  in 
that  category  were  received  from  any  one  section. 
Note  to  Technicians:  Be  sure  to  show  your  class 
of  license  on  future  contest  reports,  and  bear 
down  on  6  in  the  September  Party.  WlZWL/1, 
Paxton,  Mass.,  was  the  country's  leading  Tech- 
nician, and  the  top  50-Mc.  operator,  as  well, 
with  90  contacts  in  13  sections,  for  1170  points. 
This  was  done  without  benefit  of  sporadic-E' 
skip,  as  the  band  remained  closed  throughout 
the  contest,  as  far  as  the  Wis  were  concerned. 

The  50-Mc.  band  opened  in  other  areas,  how- 
ever, and  some  nice  scores  were  turned  in  as  a 
result.  W70AY/7  knocked  off  36  W6s  in  a  3- 
hour  Es  session  Saturday.  Their  1703-point  total 
is  believed  to  be  the  first  4-digit  V.h.f.  score  ever 
turned  in  by  a  station  in  the  Northwest.  They 
made  129  contacts  on  50,  144,  and  420  Mc. 

A  study  of  the  pile  of  logs  brings  out  many 
facets  of  the  contest  that  don't  show  in  the 
score  tabulation.  W60HQ/6,  Mt.  San  Benito, 
210  miles  northwest  of  Los  Angeles,  worked  all 
eight  California  sections  on  144  Mc.  K6GVB, 
Ukiah,  Cal.,  worked  29  stations  in  four  sections, 
all  of  which  are  more  than  50  miles  distant. 
Ukiah  is  in  the  northern  part  of  California, 
with  mountains  in  all  directions.  W2TK0  handled 
emergency  traffic  for  an  hour  following  a  CAP 
crash  and  breakdown  of  CAP  communications 
facilities.  W3TDF  soldered  the  last  connection 
on  antenna  systems  on  his  new  tower  minutes 
before  the  start  of  the  contest,  and  went  on 
to  make  203  contacts  in  22  sections,  for  4466 
points.  W2UK,  taking  his  last  fling  at  the  2- 
meter  band  before  dismantling  his  station  for 
shipment  to  the  Hawaiian  Islands,  worked  127 
stations  in  19  sections  on  144  Mc.  We  reported 
this  last  month,  tentatively,  as  the  best  section 
total  made  on  144  Mc,  but  now  we  find  that 
W2CXY  was  giving  a  new  50-element  array 
the  acid  test  in  the  party  and  duplicated  Tommy's 
section  total. 

Scores 

In  the  following  tabulation,  scores  are  listed  by  ARRL 
Divisions  and  Sections.  Unless  otherwise  noted,  the  top 
scorer  in  each  section  receives  a  certificate  award.  Columns 
indicate  the  final  score,  the  number  of  contacts,  the  section 
multiplier,  and  the  bands  used.  A  represents  50  Mc;  B, 
144  Mc;  C,  220  Mc;  D,  420  Mc;  E,  1215  Mc.  and  above. 
Multiple-operator  stations  are  shown  at  the  end  of  each 
section  tabulation.

V.H.F.  QSO  Party 

September  17th-18th 

Another  V.H.F.  QSO  Party,  open  to  amateurs 
who  can  work  any  band  or  bands  above  50  Mc, 
will  be  held  from  2:00  p.m.  Local  Standard  Time, 
Saturday,  September  17th,  to  11:00  p.m.  Local 
Standard  Time,  September  18th. 

Call  "CQ  Contest"  or  "CQ  V.H.F.  QSO  Party" 
to  get  in  touch  with  other  contestants.  During 
contact,  operators  must  exchange  names  of  their 
ARRL  sections  for  full  credit. 

Work  as  many  stations  on  as  manj'  v.h.f.  bands 
as  j^ou  can.  Count  1  point  for  successfully  con- 
firmed exchanges  of  section  information  on  2  or 
6  meters,  2  points  for  such  QSOs  on  220  or  420 
Mc,  and  3  points  on  1215  Mc.  or  higher  bands. 
To  determine  your  final  score,  multiply  this  sum 
of  contact  points  by  your  section  multiplier, 
which  increases  by  one  when  the  same  section 
is  reworked  on  another  band.  A  station  may  also 
be  reworked  for  credit  on  additional  v.h.f.  bands. 

A  certificate  will  be  awarded  to  the  top  scorer 
in  each  ARRL  section.  In  addition,  a  certificate 
will  go  to  the  high-scoring  Novice,  Technician, 
and  multioperator  station  in  each  section  from 
which  three  or  more  valid  entries  in  these  three 
special  categories  are  received. 

Submit  your  results  as  soon  as  the  competition 
is  over.  A  simple  tabulation  of  stations  and 
sections  worked,  as  shown  on  page  60  of  June, 
1953,  QST,  is  all  that  is  required.  Convenient 
reporting  forms  are  now  available  from  ARRL. 

Rules 

1)  The  contest  starts  at  2:00  p.m.  Local  Standard  Time, 
Saturday,  September  17th,  and  ends  at  11:00  p.m.  Local 
Standard  Time,  Sunday,  September  18th.  All  claimed  con- 
tacts must  fall  within  this  period  and  must  be  on  authorized 
amateur  frequencies  above  50  Mc,  using  permitted  modes  of 
operation. 

2)  Name-of-section  exchanges  must  be  acknowledged  by 
both  operators  before  either  may  claim  contact  point(s). 
A  one-way  exchange,  confirmed,  does  not  count;  there  is  no 
fractional  breakdown  of  the  1-,  2-  or  3-point  units. 

3)  Fixed-,  portable-  or  mobile-station  operation  under 
one  call,  from  one  location  only,  is  permitted.  A  transmitter 
used  to  contact  one  or  more  stations  may  not  be  used  subse- 
quently under  more  than  one  other  call  during  the  contest 
period. 

4)  Scoring:  1  point  for  completed  two-way  section  ex- 
changes on  50  or  144  Mc;  S  points  for  such  exchanges  on 
220  or  420  Mc;  3  points  for  such  exchanges  on  the  higher 
v.h.f.  bands.  The  sum  of  these  points  will  be  multiplied  by 
the  number  of  different  ARRL  sections  worked  per  band; 
i.e.,  those  with  which  at  least  one  point  has  been  earned. 
Reworking  sections  on  additional  bands  for  extra  section 
credits  is  permitted.  Cross-band  work  does  not  count.  Con- 
tacts with  aircraft  mobile  stations  cannot  be  counted  for 
section  multipliers. 

5)  A  contact  per  band  may  be  counted  for  each  station 
worked.  Example:  W2GLV  (S.N.J.)  works  WIDBM  (Conn.) 
on  50,  144  and  220  Mc.  for  complete  exchanges.  This  gives 
W2GLV  4  points  (1  -|-  1  +2)  and  also  3  section-multiplier 
credits.  (If  W2GLV  contacts  other  Connecticut  stations  on 
these  bands,  they  do  not  add  to  his  section  multiplier  but 
they  do  pay  off  in  additional  contact  points.) 

6)  Each  section  multiplier  requires  completed  exchanges 
with  at  least  one  station.  The  same  section  can  provide 
another  multiplier  point  only  when  contacted  on  a  new 
v.h.f.  band. 

7)  Awards:  A  certificate  will  be  awarded  to  the  high- 
scoring  single-operator  station  in  each  ARRL  section.  In 


addition,  the  high-scoring  multiple-operator  station  will 
receive  a  certificate  in  each  section  from  which  three  or 
more  valid  multiple-operator  entries  are  received.  Cer- 
tificates \vi\\  also  be  given  to  the  top  Novice  and  Technician 
in  each  section  where  three  or  more  such  licensees  submit 
logs.  Award  Committee  decisions  will  be  final. 

8)  Reports  must  be  postmarked  no  later  than  October  5, 
1955,  to  be  eligible  for  awards.  See  the  box  on  page  60,  June, 
1953,  QST,  for  correct  form,  or  a  message  to  Headquarters 
will  bring  a  lithographed  blank  for  your  contest  report. 


W/VE  Contest 

September  24th-25th 

The  annual  W/VE  Contest,  sponsored  by  the 
Montreal  Amateur  Radio  Club,  will  be  held 
from  6  P.M.  EST,  September  24th,  to  11:59 
P.M.  EST,  September  25th.  The  rules  are  the 
same  as  those  of  last  year.  Amateurs  in  the 
U.  S.  A.  will  be  trying  to  trade  contest  exchanges 
with  as  many  Canadians  in  as  many  provinces 
and  territories  as  possible;  VE/VO  stations  will

CONDUCTED  BY  EDWARD  P.  TILTON.  WIHDQ 


WHEN  2-meter  DX  beyond  1000  miles  or  so 
is  worked,  a  discussion  usuall.y  follows  as  to 
the  mode  of  propagation.  Was  there  a  reflec- 
tion from  an  ionospheric  layer,  50  miles  or  more 
above  the  earth,  or  did  the  signal  follow  earth 
curvature  throughout  the  route  as  the  result  of 
favorable  conditions  in  the  lower  atmosphere? 
There  seems  little  doubt  that  both  modes  have 
produced  DX  on  144  Mc,  but  the  distances 
over  which  they  make  communication  possible 
overlap  to  some  extent. 

For  a  time  the  possibility  of  ionospheric  DX 
on  144  Mc.  was  questioned,  but  several  examples 
of  long-distance  work  seem  to  have  been  of  this 
nature.  One  of  the  first  was  the  1200-mile  contact 
between  W8WXV  and  W5VY,  in  June,  1950. 
This  came  at  a  time  when  the  50-Mc.  band  was 
boiling  with  sporadic-^^  skip,  and  weather  con- 
ditions along  the  path  were  not  such  as  to  en- 
courage tropospheric  propagation.  In  June  a  year 
later  a  whole  string  of  Texas-California  contacts 
were  made.  W6ZL  and  W5QNL  set  the  1400-mile 
record  that  still  stands,  but  several  other  stations 
worked  similar  hops  only  a  few  miles  shorter. 
Here  again,  the  6-meter  band  was  going  strong, 
and  there  was  extensive  thunderstorm  turbulence 
along  the  route  that  would  appear  to  rule  out 
tropospheric  propagation. 

On  the  other  hand,  just  about  every  September 
we  have  one  or  more  2-meter  openings  of  major 
proportions  when  there  is  no  evidence  of  spo- 
radic-£'  skip  on  lower  frequencies.  The  W2BAV- 
W0DSR  contact  of  September,  1950,  was  in  the 
1200-mile  range,  and  W2BAV  was  heard  out  to 
more  than  1400  miles  on  that  occasion.  There 
have  been  contacts  beyond  1000  miles  under 
similar  conditions  every  fall  since.  The  question 
then  arises,  how  to  tell  when  favorable  conditions 
for  2-meter  DX  exist,  whether  for  Ea  or  tropo- 
spheric propagation? 

Often  during  the  early  summer  DX  season  on 
50  Mc.  we  hear  6-meter  stations  arranging  chucks 
on  2.  Practically  all  of  these  fail,  but  once  in  a 
blue  moon  one  pays  off.  Such  a  check  by  W5AJG, 
DaUas,    Texas,    started   the    1951    session    mth 


New  array  on  the  way  up  at 
VE3DIR,  Toronto.  Two  years  of  plan- 
ning went  into  this  "nest"  of  20- 
element  arrays  for  144,  220  and  420 
Mc.  The  steeplejack  is  W2ALR. 


stations  in  the  Los  Angeles  area.  Leroy  did  it 
again  on  July  3rd  of  this  year;  this  time  with 
W7LEE,  Parker,  Ariz.  They  worked  on  6  and 
then  changed  to  2  at  1242  CST,  continuing  the 
contact  successfully  on  c.w.  on  the  higher  band. 
The  144-Mc.  c.w.  signal  of  \V5AJG  was  heard  by 
\V7JU,  Boulder  City,  Nev.,  at  this  time.  W5AJG 
made  similar  checks  with  W5LFH,  Sandia  Park, 
N.  Mex.,  and  W4CVQ,  Raleigh,  N.  C,  without 
success.  The  following  day  W7LEE  heard  un- 
identified 2-meter  signals  from  the  East  again. 

The  W5AJG-W7LEE  path  is  about  1020 
miles,  which  we  suspect  is  near  the  minimum 
over  which  Eg  work  is  likely  to  be  done  on  144 
Mc.  W5LFH,  under  600  miles,  was  undoubtedly 
too  close.  W4CVQ  is  about  the  same  distance  as 
W7LEE,  but  ionization  densitj^  was  probably 
greater  on  the  western  path.  W5LFH  and 
W5SFW,  Amarillo,  Texas,  worked  on  50  Mc. 
that  day,  with  both  beams  aimed  west.  As  they 
are  onlj^  220  miles  apart,  a  high-density  cloud  to 
the  west  is  indicated. 

In  looking  for  2-meter  DX  prospects  on  6, 
we  should  not  be  fooled  by  extremely  strong 
signals  on  the  lower  band  at  500  to  1000  miles. 
A  wavery  signal  on  6  at  1200  miles  might  be  a

much  better  bet,  especiall}'  if  signals  much 
closer  in  are  heard  at  the  same  time.  If  50-Mc. 
stations  under  300  miles  away  are  heard  by  the 
ionospheric  route  (that  is,  during  a  hot  opening, 
with  signals  showing  Eg  characteristics)  there 
may  be  a  chance  of  2-meter  work  over  much 
longer  hauls.  But  don't  waste  much  time  making 
tests  with  some  big-signal  6-meter  man  700  miles 
away  under  such  circumstances;  your  best  pros- 
pects will  most  likely  be  beyond  1100  miles  dis- 
tant. And  they  will  be  south  of  Winston-Salem, 
Nashville,  Tulsa,  the  Grand  Canyon,  and  San 
Francisco,  if  past  experience  in  this  department 
means  anything. 

The  chances  for  8poradic-.E/  DX  on  144  Mc. 
will  be  sUm  until  early  next  summer,  but  the 
fall  tropospheric  DX  season  will  be  just  getting 
under  way  by  the  time  this  issue  is  mailed. 
This  kind  of  DX  knows  no  geographical  bounds, 
in  the  early  fall,  at  least.  A  close  watch  of  nation- 
wide weather  conditions  and  frequent  monitoring 
of  TV  Channels  7  to  13  (with  a  good  receiver 
and  high-gain  antenna  system)  will  provide  the 
best  indications  of  the  possibility  of  DX  on 
144,  220  and  420  Mc.  during  this  season.  The 
lower  TV  channels  and  the  amateur  50-  and 
28-Mc.  bands  are  of  little  help  in  estabHshing 
one's  chances  for  v.h.f.  DX  during  the  fall 
months. 

SO.Mc.  Expeditions  Pay  Off 

A  6-iiieter  bull  session  last  February  resulted  in  one 
of  the  most  pretentious  expeditions  ever  organized  for  the 
purpose  of  providing  v.h.f.  DX  contacts.  The  laments  of 
New  Jersey  50-Mc.  operators  over  the  lack  of  Utah  and 
Nevada  contacts  on  6  gave  W2QCY  an  idea  for  a  1955 
vacation  trip.  At  least  one  East  Coast  50-Mc.  WAS  re- 
sulted, and  scores  of  calls  all  over  the  country  were  moved 
one  or  two  more  rungs  up  the  WAS  ladder. 

Planning  of  the  expedition  began  at  once,  and  from 
February  to  June,  W2QCY  did  little  else  but  build  and 
test  equipment  and  scout  prospects  for  driving  and  oper- 
ating assistants  for  the  5000-mile  jaunt.  A  new  50-Mc.  home 
rig  was  in  the  planning  stages,  so  the  expedition  set-up  was 
built  in  de  luxe  form,  to  serve  as  a  permanent  home  station 
later  on.  The  result  was  a  transmitter  delivering  50  watte 
output  on  either  o.w.  or  a.m.  'phone,  equipped  with  gang- 


tuned  VFO  and  following  stages,  speech  clipping  and  filter- 
ing, and  all  metering  and  operating  features  necessary  for 
convenient  and  effective  use;  yet  built  in  compact  enough 
form  to  permit  installation  in  Roy's  panel  truck. 

A  recruiting  program  that  included  mention  of  the 
advance  plans  for  the  trip  in  these  pages,  and  much  on- 
the-air  talk,  was  launched  early  in  the  spring.  It  was  not 
easy  to  find  two  men  who  could  take  the  time  to  make  a 
trip  of  this  sort,  though  scores  of  fellows  felt  the  urge. 
The  first  Ukely  prospect  turned  up  was  Erret  "Reb"  Allen. 
His  license  had  lapsed  some  time  ago,  but  his  interest  in 
ham  radio  was  rekindled  by  talk  of  the  trip.  In  three  weeks 
he  had  passed  his  General  Class  exam,  and  as  K20DA 
became  a  definite  member  of  the  Project  Utah  staff.  The 
third  member,  George  Whattam,  W2CZE,  was  signed  up 
almost  at  the  last  moment. 

The  cab  of  the  1949  Dodge  panel  truck  was  equipped 
with  reflective- type  insulation,  and  the  roof  given  two 
coats  of  chrome  paint,  in  anticipation  of  desert  heat.  An 
operating  table  was  installed  in  the  truck  compartment, 
and  all  gear  readied  for  use.  Luggage  carriers  on  the  roof 
took  care  of  the  nine  10-foot  TV  mast  sections  and  the 
Telrex  6-element  array.  Gear  for  use  on  7,  14  and  21  Mc. 
was  installed.  Test  runs  were  made,  with  all  gear  and 
operators,  to  determine  their  suitability  for  the  job  coming 
up.  Letters  had  been  written  to  several  W7s  for  advice 
and  assistance,  and  the  approximate  location  was  selected 
for  the  Nevada-Utah  operating. 

The  expedition  left  Morristown,  N.  J.,  the  night  of 
July  17th,  and  by  the  morning  of  the  20th  they  were 
ready  for  a  rendezvous  with  Andy  Norgaard,  W7UPS, 
Wendover,  Utah!  Sites  were  surveyed  and  Three-Mile  Hill, 
a  mountain  just  over  the  state  line  in  Nevada,  was  selected 
for  the  first  work.  Between  then  and  June  26th,  59  different 
stations  were  worked,  winding  up  the  Nevada  stay  with 
a  fine  double-hop  opening  Sunday,  the  26th.  Eastern 
stations  worked  included  WSa  PCB  MQU  HFY  FPH, 
W2s  MEU  ZKE  KNQ  IDZ  WCM  UQQ,  and  KSa  BDF 
and  JNS.  Contacts  were  made  at  the  rate  of  one  every  90 
seconds  through  terrific  QRM. 

The  scene  of  operation  was  shifted  to  a  saddle  between 
two  peaks  NNE  of  Wendover,  Utah,  on  the  27th,  from 
which  point  26  stations  were  raised.  Conditions  were  never 
so  favorable  during  the  three  days  left  for  Utah  work, 
and  only  two  eastern  stations  were  worked:  WIVNH  and 
W2IDZ.  The  latter  made  possible  the  first  50-Mc.  WAS 
award  to  a  W2.  W2IDZ's  Certificate  No.  11  is  the  second 
to  be  issued  to  an  operator  located  east  of  W9.  Special 
QSLs  are  being  prepared  and  will  be  sent  to  all  stations 
worked. 

While  W2QCY/7  was  busy  in  Nevada,  another  Nevada 
expedition  very  similarly  equipped  was  making  hay  in 
Las  Vegas.  The  night  of  June  26th,  W6ABN/7  worked 
some  of  the  same  stations  as  W2QCY/7,  but  in  addition, 
many  Wis,  most  of  whom  had  never  heard  a  Nevada  signal 
before.  Stan  used  100  watts  input  to  an  829B,  and  a  4- 
element  array  mounted  about  10  feet  above  his  panel 
truck.  Though  he  spent  most  of  a  three-week  vacation 
in  Las  Vegas,  it  was  only  between  June  24th  and  July  4th 
that  many  contacts  were  made.  In  this  time  W6ABN/7 
worked  115  different  stations  in  27  states,  all  call  areas,  and 
VE3.  VE3AET,  the  sole  Canadian  worked  by  W6ABN/7, 
reports  that  he  abo  worked  W6COH/7,  near  Jean,  Nev., 
on  June  25th. 

The  work  of  these  stations  demonstrates  that  only 
activity  is  needed  to  make  any  state  in  the  country  available 
to  any  other  on  50  Mc.  This  is  supported  by  the  work  of 
W7JPN,  Salt  Lake  City,  and  W7QDJ,  Clearfield,  Utah, 
who  worked  many  stations  throughout  the  East  during 
July  openings.  These  two  are  the  first  Utah  home  stations 
to  work  double-hop  sporadic-^  DX,  and  as  such  they  pro-

vided  many  operators  with  their  first  Utah  contacts.  Among 
the  beneficiaries  was  WILLL,  Windsor,  Conn.,  who  worked 
both  for  No.  48  on  July  16th.  One  of  the  country's  most 
consistent  50-Mc.  DX  hounds,  Brownie  had  been  watching 
for  Nevada  and  Utah  constantly  for  several  years.  He  now 
holds  50-Mc.  WAS  Award  No.  12. 

Here  and  There  on  the  V.H.F.  Bands 

As  frequently  happens  in  peak  v.h.f.  months,  a  tremen- 
dous volume  of  mail  reached  your  conductor's  desk  during 
July.  We'll  sift  it  carefully  and  report  interesting  tidbits 
in  briefest  possible  form, 

Miles-per-watt  record  on  50  Mc?  On  July  10th  W2IDZ 
asked  a  W4  to  look  for  his  transistor  oscillator  rig,  an- 
nouncing the  frequency.  The  station  with  whom  the  test 
was  made  did  not  hear  the  flea-power  signal,  but  W4QN, 
Orlando,  and  W4AYV,  Umatilla,  Fla.,  did.  Both  called  Ed 
to  let  him  know  that  the  3.6  milliwatts  of  output  had 
produced  readable  c.w.  signals.  Ed  figures  tliis  as  something 
around  263,000  miles  per  watt.  The  rig,  built  by  W2JEP, 


W7UPS  at  the  operating  position  of 
W2ACY/7.  Complete  station  was  de- 
signed for  the  trip  from  Morristown, 
N.  J.,  to  Utah  and  Nevada. 


has  also  been  used  by  W2QCY/2,  Greenwood  Lake,  N.  J., 
to  work  40  miles  on  6-meter  ground  wave. 

It  pays  to  check  6  noontimes  if  you  can.  WIVNH, 
Agawam,  Mass.,  worked  W2QCY/7,  Utah,  during  a  noon 
opening  when  no  other  signals  were  audible.  He  was  the 
only  Wl  worked  during  tlie  entire  W2QCY  expedition. 

The  trip  to  L'tah  and  Nevada  was  so  much  fun  that  a 
Labor  Day  trip  to  West  Virginia  is  being  planned  by  the 
same  W2QCY  crew.  Advance  surveys  were  made,  so  that 
the  whole  week  end  can  be  put  to  best  use  in  providing  50- 
Mc.  contacts  with  that  hard-to-get  state.  W2QCY/8  will 
be  on  about  50.2  Mc.  from  a  high  point  near  Martinsburg, 
about  20  miles  southwest  of  Hagerstown,  Md. 

Examples  of  the  big  pick-up  in  50-Mc.  activity:  Tennessee 
stations  are  heard  whenever  the  band  is  open  in  that 
direction.  W4ZBQ  says  that  there  are  27  stations  on  50 
Mc.  in  the  Knoxville  area  alone.  W5HEZ,  Baton  Rouge, 
La.,  worked  85  different  stations  in  one  day  recently. 
WIVNH  counted  27  Ohio  W8s  during  a  July  session.  W6s 
by  the  score  have  been  heard  in  the  East  during  the  better 
double-hop  openings.  W8CMS  worked  20  states,  8  call 
areas,  July  9th.  VE3AET  heard  or  worked  56  stations  in 
16  states,  June  26th.  Fifteen-minute  tape  recording  made 
by  WIHDQ  on  June  26th  has  35  different  calls  in  17  states 
in  evidence.  W70AY/7  worked  36  W6s  in  the  June  V.H.F. 
Party.  W0ZJB  worked  44  stations  in  24  states  and  all  call 
areas,  July  8th. 

This  brings  on  a  considerable  QRM  problem,  with  every- 
one trying  to  use  the  low  end  of  the  band.  With  sparse 
occupancy  of  the  band,  concentration  on  the  first  100  kc. 
did  no  great  harm,  but  there  just  isn't  room  for  everyone 
there  any  more.  Stations  in  Channel  2  areas  need  to  work 
as  low  in  the  band  as  possible,  to  minimize  TVI.  W2IDZ 
suggests  that  where  Channel  2  TVI  is  not  a  problem,  6-meter 
men  take  it  upon  themselves  to  move  up  in  the  band,  at 
least  during  widespread  openings.  And  all  of  us  should 
tune  more  of  the  band  than  we  do.  Your  conductor,  using 
50.57  Mc.  for  mobile  work  of  late,  has  lost  plenty  of  calls 
because  fellows  don't  tune  that  high,  even  when  the  band 
is  dead.  Too  many  operators  run  up  to  about  50.4  Mc.  and 
give  up.  Let's  use  more  of  it,  boys! 

That  last  state  for  W0DZM,  Robbinsdale,  Minn.,  was 
not  Nevada  or  Utah,  but  Montana.  He  nailed  this  one 
down  with  W7JRG,  Billings,  Mont.,  July  15th.  When 
that  last  card  comes  tlirough.  Shorty  will  be  in  line  for 
Award  No.  13.  All  48  were  worked  with  30  watts  input 
to  an  815,  which  may  be  the  low-power  record  for  50-Mc. 
WAS.  Two  near-misses:  W0TKX,  wlio  missed  the  shot  at 
W2QCY/7  and  W6ABN/7  by  being  out  on  Field  Day,  and 
W9VZP,  who  raised  W6.\BN/7  just  as  Stan  developed 
transmitter  trouble  and  couldn't  reply. 

Six-meter  oddity:  W8WVP  finished  his  rig  and  installed 
his  antenna  system  on  July  9th.  His  first  CQ  on  6  raised 
W5ZVF,  who  had  also  just  finished  erecting  a  beam  and 
putting  liis  station  in  order  in  a  new  location,  making 
his  first  transmission  in  calling  W8WVP.  It  was  the  first 
Michigan  contact  for  W5ZVF,  and  the  first  Arkansas  con- 
tact for  W8WVP. 

W0ZJB,  Wichita,  Kan.,  suggests  the  possibility  of  an 
out-of-tliis-world  2-meter  net  that  could  be  put  into  service 


September  1955 


by  using  high  TV  towers  during  the  station's  off-the-air 
hours.  TV  transmitting  arrays  are  broadband  affairs. 
They  are  several  hundred  feet  higher  than  any  ham  is 
likely  to  get  his  antenna,  and  they're  fed  with  low-loss 
lines.  They  may  not  have  the  best  match  in  the  world  for 
144  Mc,  but  even  with  a  high  s.w.r.  (who's  worrying,  at 
amateur  power  levels?)  they  still  do  quite  a  job  on  2. 
W5DFU  and  W5VKH  have  used  a  600-foot  tower  for  Chan- 
nel 8  at  Muskogee,  Okla.,  on  several  occasions.  W5I0W  has 
worked  Mississippi,  Oklahoma,  Texas  and  Kansas  with  fine 
sigs  on  the  Channel  10  array  at  Ada,  Okla.  Vince  now  plans 
to  use  the  Channel  10  array  of  KAKE,  Wichita,  the  night  of 
Sept.  10th,  and  the  following  morning.  He  will  be  on  144.32, 
and  would  like  to  have  as  many  fellows  as  possible  keep 
a  sharp  lookout  for  W0ZJB/0  at  that  time. 

This  should  be  something  for  some  of  the  members  of  the 
"Flashlight  Net"  reported  by  W3KCA,  Greenmount,  Md. 
These  are  hams  who  work  at  radio  and  TV  stations,  and 
consequently  cannot  be  on  the  air  during  the  popular  eve- 
ning hours.  WSs  HFG  OWW  QFM  OLR  YPL  BJG  SST 
KCA  and  YQO  cannot  be  on  the  air  before  0100.  They  hold 
forth  each  morning  until  0300  or  later,  and  invite  others  to 
join  in.  They  use  145.62  Mc.  for  a  net  frequency,  but  look 
for  other  callers  regularly. 

VE3DIR,  Toronto,  is  another  all-nighter.  Tony  gets 
home  late  and  has  a  tough  time  making  contacts  on  144  Mc. 
He  calls  CQ  to  the  west  at  0100,  but  usually  finds  it  a  lonely 
proposition. 

A  midnight  watch  is  kept  each  Saturday  on  50  Mc.  by 
the  Royal  Order  of  Hootowls,  of  Seattle,  Wash.  W7YJE  has 
a  certificate  available  to  any  6-meter  operator  who  will 
join  their  hooting  on  6  for  one  hour  beginning  any  Saturday 
at  midnight.  Net  frequency  is  50.4  Mc,  and  charter  mem- 
bers are  W7s  YJE  TMU  VIC  UFE  and  VMH. 

South  Carolina  has  been  beyond  the  horizon  for  2-meter 
men  of  the  Eastern  Seaboard,  so  it  looked  like  a  good  place 
to  spend  a  vacation  to  W2FBR  and  W2FBZ.  Accordingly, 
they  set  out  for  two  weeks  at  Myrtle  Beach,  S.  C,  in  June. 
Using  a  6146  rig  and  a  24-element  portable  array,  Ralph 
and  Lee  operated  on  2  from  June  20th  to  July  1st,  providing 
first  South  CaroUna  contacts  for  W4s  in  North  CaroUna  and 
Virginia.  No  South  Carolina  stations  were  heard,  though 
contacts  were  made  regularly  with  W4CVQ,  Raleigh, 
K4AMX,  Winston-Salem,  W4MDA,  Wilmington,  W4NtQ 
and  W4SMA,  WhiteviUe,  and  other  North  Carolina  stations. 
On  June  30th  they  worked  W4s  IKZ  OLK  WE  ZBU  and 
SCJ  in  the  area  around  Norfolk,  Va.,  about  280  miles  to  the 
north.  Skeds  were  kept  each  morning  with  WIHDQ  and 
others,  but  there  was  no  real  band  opening  to  the  north 
during  their  stay,  so  no  DX  was  worked.  Just  a  few  nights 
previous  to  the  arrival  of  W2FBR/4,  the  North  Carolina 
stations  had  a  field  day  with  Wis  and  2s  on  144  Mc! 

A  new  mountainous  path  broken  down  on  144  Mc. 
W7UVH,  Olympia,  Wash.,  writes  that  he  and  W7PVZ, 
and  W7LHL,  Seattle,  now  work  W7HEA,  Toppenish,  Wash. 
This  is  only  about  130  miles  in  each  case,  but  the  Cascade 
Range  intervenes.  Big  antennas  (horizontal)  and  improved 
receivers  seem  to  be  major  factors  in  breaking  down  this 
circuit.  We  showed  W7LHL's  96-element  array  last  month. 
W7UVH  has  a  24-element  job  composed  of  six  4-element 
Yagis. 

VE7FJ,  New  Westminster,  B.  C,  works  into  the  Portland 
area,  260  miles  to  the  south,  when  conditions  are  good. 
Using  horizontal  polarization  he  has  connected  with  W7s 
SEZ,  NNR  and  OKV.  Art  would  like  to  see  a  "  v.h.f.  circuit 
of  the  month"  in  each  issue  of  QST.  So  would  your  con- 
ductor. We'll  be  glad  to  run  information  on  any  novel  ideas 
you  fellows  care  to  send  in,  as  we  have  in  the  past.  We  need 
more  material  to  make  it  a  regular  thing,  however. 

Anyone  for  Bermuda  on  144  Mc?  VP9BM  is  all  set  and 
will  keep  schedules.  He  is  on  144.35  Mc.  VP9AY,  who  was 
making  contacts  on  50  Mc,  has  left  Bermuda  and  is  now  on 
duty  at  Selfridge  Field,  near  Detroit.  VP9BM  will  keep 
skeds  on  20,  for  checks  on  2.  Address:  M/Sgt.  J.  W.  Wen- 
glare,  1934  AACS  Sqdn.,  APO  856,  New  York,  N.  Y. 


September  V.H.F.  Party  Coming  Up 

Elsewhere  you'll  find  the  announcement  of  the  regular 
fall  v.h.f.  contest.  Note  two  minor  changes  in  tlie  rules  for 
this  and  subsequent  contests.  Because  of  the  difficulty  in  es- 
taVjlisliing  the  exact  location,  and  the  ease  with  which  they 
move  from  one  section  to  another,  contacts  with  aircraft 
stations  are  ruled  out  hencefortli   for  section  credits.  All

moving  stations  have  been  excluded  from  competition  by  the 
rules  for  some  years,  though  many  provide  contacts  for 
participants,  and  we  hope  that  they'll  continue  to  do  so.  But 
if  you  work  an  aircraft  over  a  section  you  don't  catch  with 
a  ground  station,  you  can't  count  the  section  hereafter. 
Makes  it  fairer  for  everyone,  we  feel. 

Another  change  has  been  made,  to  bring  v.h.f.  contest 
rules  into  conformity  with  the  Field  Day  rules,  and  to 
prevent  excessive  numbers  of  contacts  with  a  single  piece 
of  equipment.  A  rig  used  to  make  one  or  more  contacts  in 
the  contest  can  be  used  thereafter  under  only  one  additional 
call.  You  work  from  home  with  a  Communicator,  say.  Then 
you  can  go  out  and  work  from  a  portable  location  with  the 
same  rig.  That's  legal  and  logical  so  far.  But  your  wife  (or 
girl  friend  or  anyone  else  who  is  licensed)  cannot  then  take 
the  rig  and  make  more  contacts  under  another  call.  This  is 
designed  to  prevent  "manufactured"  contacts,  and  to  make 
the  contest  results  a  more  accurate  indication  of  the  extent 
of  v.h.f.  activity  in  any  area. 

And  here's  some  advance  information  on  events  sched-

QST  for

CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD 


However: 

Amateurs  who  joined  the  countries  race  within 
the  past  four  years  find  themselves  at  a  certain 
disadvantage  with  respect  to  their  OT  competi- 
tors in  DX  ranks.  The  U.S.S.R.  portions  of  their 
ARRL  DXCC  Countries  List  check-off  sheets 
are  bare  as  Mama  Hubbard's  celebrated  cup- 
board. It's  indeed  difficult  for  the  new  school  to 
visualize  how  plentiful  and  workable  those  U 
signals  were  during  years  immediatelj^  following 
World  War  II. 

Anyway,  around  1951  they  stopped  coming 
back.  At  the  same  time  receipt  of  QSLs  from 
Russian  stations  dwindled  to  zero.  That  is  the 
situation  generally  maintaining  today.  Stations 
bearing  U.S.S.R.  amateur  prefixes,  while  quite 
frequently  heard,  work  only  each  other  and 
satellite-country  stations  ^  —  except  in  curious 
and  isolated  instances.  An  increase  in  these  rare 
exceptions  to  the  rule  is  what  prompts  Jeeves  to 
bring  things  up  to  date  by  recording  here  the 
status  of  1955  DXing  with  respect  to  the  Iron 
Curtain. 

Beginning  last  year  UB5s  in  the  Odessa  area 
began  QSOing  and  QSLing  on  a  modest  world- 
wide basis.  Other  U  stations  now  give  scattered 
comebacks  but  deliver  no  QSLs.  This  may  estab- 
lish a  trend  but  the  pattern  still  is  too  vague  to 
be  much  of  a  pattern.  A  spot-check  of  the 
"How's"  mailbag  turns  up  the  following  Russian 
call  signs  logged  in  North  America  on  20-  and 
40-meter  c.w.  during  the  past  several  weeks: 

UAls  CF  DH  KAE  KAI  KAQ  KFA  KIA  KJA  RF  TT. 
UA3s  AF  CR  DH  EG  FE  KAF  KBD  KET  KMB  KWA 
MP  TV,  UA48  HI  KCE  KKC  KPA  KV.  UA6s  KAB  KOB, 
UA9s  CM  DH  KOG  KQB,  UA0s  KAD  KCA  KCI  KKB 
KOA  KOH  SJ,  UB5s  BP  CF  CI  CR  KAA  KAB  KAC  KAD 
KAG  KHE,  UC28  KAB  KAC  KBC,  UD68  KAB  KAD, 
UF6KAF,  UG6AL,  UI8KBA,  UJ8KAA,  UM8KAA, 
UNI  KAA,  U05s  A  A  KAA,  UP2s  AA  KBC,  U02s  AN 
KAA,  UR2KAA. 

Some  have  swapped  reports  with  stations  out- 
side the  Curtain.  A  few  have  produced  QSLs. 
These  U  stations,  almost  invariably  multi- 
operator  manned,  usually  are  heard  working  each 
other  in  periodic  organized  activities.  Their  ripply 
signals  are  generated  by  gear  which  apparently 
is  on  a  par  with  U.  S.  ham  equipment  of  the 
1930s.   Their  operating  technique,   however,   is 

*  Please  mail  all  reports  of  DX  activity  to  DX  Editor 
Newkirk  at  4128  North  Tripp  Ave.,  Chicago  41,  Illinois. 

1  Satellite-country  stations  bearing  amateur  prefixes  — 
DM  HA  LZ  OK  SP  YO,  etc.  —  continue  limited  world-wide 
activity,  QSOing  both  sides  of  the  Curtain.  In  Albania 
and  Red  China  ham  radio  in  any  form  appears  to  be  nil. 
See  "Whence"  for  info  on  the  licensing  structure  in  a  typical 
satellite  country. 


capable;  fast  break-in  and  30-w.p.m.  code  speeds 
are  common. 

Beyond  the  preceding  evidences  Churchill's 
descriptive  "riddle  wTapped  in  a  mystery  inside 
an  enigma"  easily  still  includes  Russian  amateur 
radio.  That  chink  we  now  perceive  in  the  radio 
Curtain  is  neither  extensive  nor  is  it  necessarily 
permanent. 

The  DX  contest  season  is  upon  us!  Brazil's 
annual  LABRE  affair  comes  off  early  this  month 
(see  p.  126,  August  QST)  and  DARC  of  Germany 
throws  its  WAE  Test  (see  "Whence")  shortly 
thereafter.  In  October  the  VK/ZL  show  will  take 
the  stage.  Battle  stations!  .  .  . 


What: 

A  general  call  to  quarters,  too,  for  our  yearly  African  DX 
hunting  season.  "Ye'U  take  the  long  path  and  I'll  take  the 
short  path  and  the  W6s  will  be  in  Kenya  before  us,"  as  the 
GMs  oft  lament  to  each  other.  Anyway,  our  DX  bands 
will  see  the  Dark  Continent  boiling  through  with  excellent 
openings  —  even  10  meters  is  slated  to  join  the  party  now 
and  then.

Asia  —  The  Nicobar  Islands  have  been  inconspicuous  by 
their  ham-band  ab.sence  since  VU5AB  shut  down  a  couple 
of  years  ago.  VS2DQ  observes:  "A  recent  VU5AB  definitely 
is  a  pirate.  There  are  VSl  amateurs  who  visit  there  regularly 


and  sometimes  stay  there  a  considerable  time.  But  licenses 
are  issued  by  the  government  of  India  and,  alas,  it  seems 
impossible  for  any  of  the  VSl  boys  to  get  one."  VSIGO 
affirms  this  in  penning  WIWPO:  "Haven't  heard  any 
further  about  the  VU5  deal  —  guess  that's  fallen  through. 
I  return  to  the  U.K.  in  the  fall,  anyway."  VSIGO  (ex- 
VS9AW)  has  been  working  160,  80  and  40  meters  but  hopes 
to  get  in  some  sessions  on  20,  15  and  10  before  moving 
Europeward.  Reliable  power  components,  he  says,  are  ex- 
tremely difficult  to  come  by  over  there  ._._._  AC4NC,  on 
leave  in  Calcutta  of  late,  is  expected  to  be  back  in  action 

at  the  Tibet  Indian  Mission  before  long W5EVW, 

trying  his  luck  as  MP4BBT,  verifies  that  MP4s  QAG  and

legitimate  ham  licenses  but  HSl  authorities  still  haven't 
bothered  to  remove  their  country  from  the  International

month's  QST).  W6Z0L  ran  across  one  HSIBC  on  40  c.w.

Oceania  —  ZC3AC  was  plagued  by  transformer  burn- 
out troubles  throughout  the  summer  —  winter  on  Christmas 
—  but  VS2DQ  finds  him  still  hopeful  of  a  full-scale  14-Mc. 
onslaught  before  1956  sets  in.  Christmas  Island  has  no  air- 
strip, receiving  mail  but  once  monthly  by  sea  from  Malaya 
or  AustraUa.  High  humidity  remains  the  curse  of  tropical 
electronics;  FW8AB  of  WaUis  also  fights  continual  power- 
component  failings  ._._._  VK90K  has  another  year  or 
so  left  on  Norfolk  Island,  according  to  E.  G.  Riggle.  Len 
most  of  all  desires  consistent  contact  with  the  United  King- 
dom but  the  G  paths  are  rarely  open  for  him  on  20  . 

According  to  Amateur  Radio  of  WIA,  W2CPN  (ex-W9RCQ) 
is  making  quite  a  hit  during  his  Down  Under  visit.  Also, 
shipboarders  XINE  and  XINP  again  are  hamming  on  14

Europe  —  DARC  (Germany)  invites  world-wide  par- 
ticipation in  its  WAEDC  contest,  an  interesting  new  affair 
Biheduled  for  (c.w.)  0000  GMT  Sept.  17th  to  2400  on  the 
18th,  and  ('phone)  the  same  hours  Sept.  24th-25th.  Euro- 
pean stations  will  QSO  non-European  stations  on  all  bands 
3.5  through  28  Mc.  The  serial  exchange  is  the  usual  five- 
digit  ('phone')  and  six-digit  (c.w.)  numeral  —  RSTOOl , 
RST002,  etc.  Scoring  (for  non-European  entries):  Each 
completed  QSO  counts  one  point  and  each  station  can  be 
worked  but  once  per  band.  Additional  points  can  be  earned 
Ijy  transmitting  "QSO  reports"  to  European  stations,  these 
designated  as  "QTC"  at  one  point  each.  Each  QTC  consists 
of  three  parts—  (1)  time  in  GMT,  (2)  station  call,  and  (.3) 
QSO  number,  of  any  previous  WAE  Test  QSO.  For  instance,

W5XXX  raises  DL7AA  and  thereby  garners  a  QSO  point; 
W5XXX  previously  worked  G6ZO  at  1207  for  GGZO's 
113th  Test  QSO.  So,  in  addition  to  the  QSO  point  for  his 
DL7AA  contact,  W5XXX  gains  another  point  if  he  sends 
"1207/G6ZO/113"  to  DL7AA.  As  many  as  ten  QTCs  can 
be  sent  per  QSO  but  each  QTC  can  be  sent  but  once.  Ergo, 
the  more  QSOs  you  rack  up,  the  more  QTCs  you  have 
available  to  parlay  into  additional  points.  More  additional 
points,  termed  bonus  points,  are  gained  by  working  a  station 
on  three  different  bands  (2  points),  four  bands  (3  points) 
and  five  bands  (4  points).  Multipliers  are  derived  from  a 
modified  version  of  DARC's  WAE  Award  countries  list,  as

Perennially  a  feature  in  DX  doings  is  the  sudden 
appearance  of  HBl  portables  on  DX  bands  during  the

Two  unsohcited  bouquets  from  the  Continent  for  of  ten-ma- 
Ugned  W  DX  chasers.  SM5ARP,  reference  his  recent  summer 
idyl  in  Monaco:  "Had  much  trouble  with  the  3A2AW  rig 
this  time,  lots  of  troubleshooting.  W  manners  were  excellent 
and  permitted  speedy  operation."  And  from  HB9HT  of 
Swiss  FD  set-up  HBIHT:  "I  would  hke  to  express  our 
thanks  to  all  the  many  W  stations  who,  with  their 
snappy  operating,  were  a  great  deal  responsible  for  .  .  .  our 
high  score."  ._._._  IR'TS  (Eire)  had  a  field  day,  too  — 
everybody's  doing  it  —  and  declares  that  "this  year's  Na- 
tional Field  Day  will  go  down  on  record  as  one  of  the 
wettest  ever  experienced."  [No,  Boss,  they  mean  rain. — 
Jeeves]  ._._._IlsBRN  and  DCO  gave  the  gang  some  good

napping  on  this  quickie.  Hayden  is  among  the  many  W/K 
brethren  on  the  watch  for  an  HBl  or  HB9  in  Valais  canton,

with  111  countries  to  his  150-watter's  credit,  states  that  his 
is  the  most  nortliern  ham  station  in  Scotland.  Furthermore, 
he  and  GM3BZJ  are  the  only  amateurs  in  County  Caith- 
ness. GM3JDR  still  needs  Miss.,  Nev.,  N.  Mex.,  S.  Dak. 
and  Utah  for  WAS  and  guarantees  100  per  cent  QSL 
._._._  Supplementing  this  month's  introductory  remarks, 
W9UKG  passes  along  info  on  the  Hungarian  ham  set-up. 
There  are  about  00  HA  licensees  active,  about  half  of  which 
operate  collective  (multiop)  layouts.  The  remainder  stick 
to  v.h.f.  bands.  License  classifications  go  like  this:  Ultrahigh, 
10  watts  input  from  144  to  10,500  Mc;  Class  A,  10  watts 
on  3500-3850  kc,  c.w.  only,  for  one  year;  Class  B,  50  watts 
on  "all  bands"  with  all  permitted  emissions;  and  Class  C, 
200  watts,  same  as  Class  B  otherwise.  HA5KBA,  the  Hun- 
garian "headquarters  station,"  appears  to  be  in  a  class  by 
itself  with  a  flock  of  operators,  750  watts  input  and  much 
American-made  equipment  ._._._  DM2ABK  informs 
W9UKG  that  three  East  German  prefixes  now  are  in  use: 
DM2  for  "private"  amateur  stations,  DM3K  for  collective 
stations,  with  DM0K  calls  representing  individual  operators 
of  collective  stations.

New  Season  Ahead.  September  marks  the 
l)eginning  of  another  operating  season!  The  old 
sunspot  cycle  has  definitely  turned  the  corner,  is 
over  a  year  on  its  way,  and  such  bands  as  10  and 
15  meters  will  be  open  for  longer  periods  with 
more  DX  offered  up  for  those  alert  to  work  it. 
Net  activity  and  traffic  will  continue  to  be  well 
supported  as  the  nets  "up"  their  number  of  ses- 
sions and  the  amateurs  returning  from  vacation 
get  back  in  the  swim.  The  v.h.f.  activities  this 
September  (and  at  other  periods  in  the  season 
schedule)  should  be  the  best  ever;  there  were 
new  highs  in  accomplishments  and  participation 
in  the  '54-'55  season.  Don't  overlook  the  chance 
to  get  into  the  FMT  (Frequency  Measuring  Test) 
on  the  evening  of  September  15th  .  .  .  see  an- 
nouncement elsewhere  in  these  columns. 

Individual  report  of  FMT  results  is  sent  you, 
if  you  report,  and  with  an  information  copy  to 
the  appropriate  SCM.  This  is  so  that  if  you  do 
well  enough  this  can  document  your  application 
to  the  SCM  for  an  Observer  post  in  the  frequency 
measuring  classes.  But  more  amateurs  are  needed 
in  00  operations  to  send  "cooperative  mail  no- 
tices" to  fellow  amateurs  to  help  them  avoid 
FCC  citations,  also  "for  better  operating." 
Whether  or  not  appointed  in  a  frequency  measur- 
ing classification  you  can  get  lined  up  for  c.w.  or 
'phone  observing  posts  aside  from  frequency 
measuring. 

For  RMs,  PAMs  and  NCSs  who  have  not  al- 
ready done  so,  this  is  a  reminder  that  it  is  time 
to  reregister  the  frequency  and  operating  periods 
of  all  nets  to  get  them  included  in  the  annual  Net 
Directory. 

On  the  Correct  Handling  of  Messages.  Dur- 
ing the  vacation  season,  the  undersigned  was 
shocked  to  get  the  radio  suggestion  from  one 
member  of  a  'phone  net  to  whom  a  message 
was  being  relayed  that  he  would  change  the 
text;  he  thought  it  more  clear  if  the  text  were 
worded  a  different  way!  Let  it  be  clear  to  every- 
one, once  and  for  all,  that  it  is  a  standing  com- 
munications principle  in  all  communications 
systems  worthy  of  the  name  that  the  text  of  the 
message  cannot  be  changed  except  by  the  originator. 
To  do  so  would  result  in  distortions  of  meanings, 
and  lack  of  confidence  in  any  such  undependable 
service  that  turned  out  messages  with  modified 
texts.  Besides  watching  such  things  that  by 
observance  spell  out  sound  communication 
practices,  every  new  and  old  traffic  handler  is 
urged  to  require  "place"  and  "date"  given  with 
the  other  vital  information  preambles  should 
include.   The  check  is   helpful   and   important. 


GEORGE  HART,  WINJM,  Natl.  Emerg.  Coordinator 
ELLEN  WHITE,  WIYYM,  Asst.  Comm.  Mgr.,  'Phone 
LILLIAN  M.  SALTER,  WIZJE,  Administrative  Aide 

Our  young  friend  who  volunteered  to  add  a 
word  to  the  text  had  apparently  no  thought 
that  this  would  not  be  compatible  with  the 
group  count  that  the  message  already  carried ! 

It  should  in  fairness  be  said  that  the  over-all 
picture  of  vacation  message  service  was  impres- 
sively good  and  co  Operation  high  in  all  directions. 
Many  functioning  nets  were  observed. 

FD  Post-Mortems.  W8ENS  (Springfield,  Ohio, 
Amateur  Radio  Club)  compares  the  exigencies 
of  the  Field  Day  to  those  of  civil  defense  or 
emergency  operations.  He  says  planning  should 
involve  tents  painted  with  a  broad  stripe  to 
identify  them,  stakes  the  same  color  (80-meter 
tent  with  red  poles  and  stakes,  for  example).  A 
100-foot  rope  to  attach  to  the  power  unit  to 
prescribe  the  exact  distance  to  set  up  the  different 
tents  would  have  helped.  W8ENS  notes  the  con- 
trast between  loud  emergency  talkers  and  joiners 
and  the  "amazing  few  that  show  up  when  the 
real  shake  is  on."  As  he  puts  it,  where  would  we 
stand  if  members  of  an  emergency  group  had 
never  put  up  a  wire  in  rain,  sleet  or  ice  or  didn't 
own  a  pair  of  boots  or  raincoat,  nor  had  a  gallon 
of  gasoline  stashed  away  for  use  in  emergency? 
One  objective  of  Field  Day  is  to  learn  these 
things.  (We  gather  there  was  rain  in  Ohio  and 
some  missing  items  for  coping  with  these  offenders 
speedily  and  with  highest  efficiency!) 

W7IIGL  in  the  wee  Sunday  morning  hours  of 
FD  heard  many  calls  sent  poorly  and  too  fast.  He 
reduced  his  17-w.p.m.  speed  to  set  a  striking 
example  of  change  in  technique  and  reports  the 
results  worthy  of  duplication.  He  says,  "Chang- 
ing to  8  w.p.m.  I  called  CQ  FD.  The  result  was 
immediate,  four  slow  but  clean  replies.  In  the 
next  hour  sticking  to  8  w.p.m.  I  doubled  the  num- 
ber of  contacts  per  hour." 

The  Joliet  Amateur  Radio  Society  in  "Ground- 
Waves"  reviews  its  performance  and  for  the 
record  lists  six  points  it  will  take  up  for  next  year. 
Other  groups  may  have  a  different  list  but  some 
points  are  sure  to  be  generally  applicable:  (a) 
have  not  less  than  four  operators  for  each  posi- 
tion; (b)  each  operator  to  be  given  a  chance  to 
practice  with  transmitter  and  receiver  before  FD 
to  minimize  f umbling-time ;  (c)  plan  beams;  (d) 
use  speech  compression;  (e)  arrange  training 
Novices  to  improve  logging  and  assist  checking, 
several  advance  one-hour  sessions. 

All  early  reports  indicate  that  several  groups 
topped  last  year's  showing.  It's  amazing  to  us 
that  eyes  are  so  soon  focused  on  '56  plans.  QST 
will  have  more  on  preliminary  results  for  this 
year  soon.

For  Enjoyable  Operating.  The  quarterly 
(summer)  CD  Party  in  July  was  the  day-off  or 
"chance  to  live  it  up"  for  the  whole  family  of 
ARRL  appointees.  Sometimes  the  newer  ama- 
teurs write  in  to  ask  about  these  things  and  we 
are  only  too  glad  to  tell  all  readers  about  the 
set-up. 

The  operating  highlights  for  appointees  known 
as  CD  Parties  are  scheduled  four  times  a  year, 
usually  in  the  later  weeks  of  January,  April,  July 
and  October.  Such  radio  get-togethers  promote 
fraternalism.  One  meets  fine  operators  and  has 
QSOs  "all  over"  wherever  the  equipment  used 
is  flexible  enough  to  permit  changing  easily  from 
band  to  band.  There  can  be  long  chats  or  fast 
contacts  and  an  unparalleled  opportunitj'  to  test 
station  range  and  consistency. 

To  be  an  ARRL  appointee  one  has  to  agree  to 
send  consistent  activity  reports  monthly  to  his 
SCM  (address  page  6,  QST).  The  activity  in  a 
selected  SCM-appointment  status  that  assists 
fellow  amateurs  earns  the  right  to  participate  in 
the  quarterly  radio  activities  as  they  come  along. 
The  idea  is  that  appointees  do  more  for  each 
other  and  fellow  amateurs  than  in  casual  work, 
each  appointment  being  dedicated  to  particular 
aims.  Send  a  radiogram  or  a  postal  card  for  a 
copy  of  "Operating  an  Amateur  Radio  Station" 
for  detailed  information  on  each  appointment 
post.  If  you  are  more  than  a  casual  amateur  and 
have  some  time  to  dedicate  to  definite  objectives, 
get  your  SCM  to  accept  your  application  for 
appropriate  station  or  leadership  appointments 
along  the  lines  of  your  natural  interest.

FREQUENCY  MEASURING  TEST. 
SEPTEMBER  15TH 

All  amateurs  are  in\dted  to  try  their  hand  at  frequency 
measuring.  WlAW  vfiU  transmit  signals  for  the  purpose  of 
frequency  measurement  starting  at  9:30  p.m.  EDST  (6:30 
P.M.  PDST),  Thursday,  September  15th.  The  signals  -will 
consist  of  dashes  interspersed  with  station  identification. 
These  \vi\\  follow  a  general  message  sent  to  help  listeners  to 
locate  the  signals  before  the  measurement  transmission 
starts.  The  approximate  frequencies  used  will  be  3622, 
7054  and  14,078  kc.  About  4J^  minutes  mil  be  allowed  for 
measuring  each  frequency,  with  long  dashes  for  measure- 
ment starting  about  9:36  p.m.  It  is  suggested  that  fre- 
quencies be  measured  in  the  order  listed.  Transmissions  will 
be  found  ^vithin  5  or  10  kc.  of  the  suggested  frequencies. 

At  12:30  A.M.  EDST,  September  16th  (9:30  p.m.  PDST, 
September  15th),  WlAW  will  transmit  a  second  series  of 
signals  for  the  Frequency  Measuring  Test.  Approximate 
frequencies  used  \vill  be  3675,  7046  and  14,125  kc. 

Individual  reports  on  results  will  be  sent  to  all  amateurs 
who  take  part  and  submit  entries.  When  the  average  ac- 
curacy reported  shows  error  of  less  than  71.43  parts  per 
million,  or  falls  between  71.43  and  357.15  parts  per  million, 
participants  will  become  eligible  for  appointment  by  SCMs 
as  Class  I  or  Class  II  OOs  respectively. 

This  ARRL  Frequency  Measuring  Test  will  be  used  to 
aid  qualification  of  ARRL  members  as  Class  I  and  Class  II 
observers.  Present  observers  not  demonstrating  the  requisite 
average  accuracy  wiU  be  reclassified  appropriately  until  they 
demonstrate  the  above-stated  minimum  required  accuracy. 
Class  I  and  Class  II  OOs  must  participate  in  at  least  two 
FMTs  each  year  to  hold  appointments.  SCMs  (see  listing, 
page  6)  invite  applications  for  Class  III  and  IV  observer 
posts,  good  receiving  equipment  being  the  main  require- 
ment. All  observers  must  make  use  of  the  cooperative  no- 
tices (mail  forms  provided  by  ARRL)  reporting  activity 
monthly  through  SCMs,  to  warrant  continued  holding  of 
appointment. 

Any  amateur  may  submit  measurements  on  one  or  all 
frequencies  listed  above.  No  entry  consisting  of  a  single 
measurement  will  be  eligible  for  QST  listing  of  top  results ;  at 
least  two  readings  should  be  submitted  to  warrant  QST 
mention.  Listing  will  be  based  on  over-all  average  accuracy, 
as  compared  with  readings  made  by  a  professional  fre- 
quency-measuring lab.

CODE  PROFICIENCY  PROGRAM 

Twice  each  month  special  transmissions  are  made  to 
enable  you  to  qualify  for  the  ARRL  Code  Proficiency  Cer- 
tificate. The  next  qualifying  run  from  WlAW  will  be  made 
on  September  14th  at  2130  EDST.  Identical  texts  will  be 
sent  simultaneously  by  automatic  transmitters  on  1885, 
3555,  7125,  14,100,  21,010,  52,000  and  145,600  kc.  The  next 
qualifying  run  from  W60WP  only  will  be  transmitted  on 
September  3rd  at  2100  PDST  on  3590  and  7138  kc. 

Any  person  may  apply;  neither  ARRL  membership  nor 
an  amateur  license  is  required.  Send  copies  of  all  qualifying 
runs  to  ARRL  for  grading,  stating  tlie  call  of  the  station  you 
copied.  If  you  qualify  at  one  of  tlie  six  speeds  transmitted,

TRAINING-AID  NOTES 

AffiUated  clubs  will  want  to  note  the  addition  of  two 
films  to  the  League's  visual  aids  hbrary.  The  General 
Electric  Company  has  placed  two  films  on  deposit  for  use 
by  affiliated-club  groups,  whose  secretaries  are  invited 
to  write  in  to  the  ARRL  Communications  Department  for 
booking  information. 

1)  "And  a  Voice  Shall  Be  Heard,"  22  minutes,  black 
and  wliite  sound.  The  importance  of  communications  in 
coordinating  the  reUef  activities  of  a  disaster-stricken 
city  is  demonstrated  with  emphasis  on  the  part  played  by 
the  radio  amateur. 

2)  "Principles  of  Electricity,"  20  minutes,  color  sound. 
This  animated  film  gives  individual  treatment  to  the  volt, 
ampere,  ohm,  etc.  The  latter  portion  explains  the  essence 
of  magnetism  and  magnetic  fields. 


Note  too  the  new  addition  of  a  slide  collection,  produced 
by  the  Rochester  Antique  Wireless  Association,  the  object 
of  wide  acclaim  throughout  the  country.  Titled  "The  First 
Thirty  Years  of  Amateur  Radio,"  the  slides  and  accompany- 
ing tape-recorded  lecture  are  sure  to  please  old  and  new 
club  members  alike.  Affiliated  club  officers  are  urged  to  fol- 
low standard  booking  procedure,  allowing  ample  notice  and 
choice  of  dates.  Address  all  correspondence  to  the  League's 
Communications  Department.

QST  for 


The  dates  for  this  year's  Simulated  Emergency  Test  have 
been  set  as  October  8th-9th  (see  Activities  Calendar,  June 
and  subsequent  issues  of  QST).  Now  don't  say  you  weren't 
given  advance  notice.  The  customary  bulletin  will  be  in  the 
hands  of  ECs  by  the  end  of  this  month. 

We've  been  doing  some  thinking  about  the  SET.  Wish  you 
would,  too.  In  past  years,  we  have  been  most  liberal  with 
dates  on  each  side  of  the  designated  week  end,  and  this  has 
resulted  in  ability  of  ECs  to  combine  SET  with  local  ci\'il 
defense  or  Red  Cross  activities,  or  pick  a  date  or  week  end 
more  convenient  for  AREC  registrants.  It  has  had  the  dis- 
advantage of  detracting  from  the  nation-wide  demonstration 
aspect  of  our  SET,  about  which  we  are  usually  called  by 
newspapers  and  press  associations. 

The  SET  is  the  ARRL's  and  the  amateur's  own  exercise. 
It  has  been  conducted  every  year  since  1947,  in  conjunction 
with  whatever  agencies  the  AREC  is  ser\'ing.  Naturally, 
since  the  Red  Cross  is  and  always  has  been  one  of  the  pri- 
mary agencies  to  be  served,  it  played  a  key  part  in  the  exer- 
cise, to  the  extent  that  many  amateurs  got  the  impression 
that  the  SET  was  a  Red  Cross  test.  In  these  cold-war  days, 
civil  defense  has  become  more  important,  and  inevitably 
c.d.  has  played  a  bigger  part  each  year  in  the  SET.  Such 
participation  has  not  necessarily  been  at  the  expense  of  Red 
Cross  participation,  although  in  some  places  where  the 
emphasis  has  shifted,  this  has  been  the  net  effect. 

We  would  Uke  to  request  that  ECs,  if  at  all  possible,  this 
year  plan  their  SET  for  the  designated  week  end.  We  expect 
to  continue  the  liberal  policy  regarding  dates,  and  any  par- 
ticipation within  a  week  or  more  of  the  October  8th-9th 
week  end  will  be  considered  eligible  for  inclusion  in  the  SET 
data.  But  it  makes  a  better  national  impression  if  we  all 
conduct  our  tests  at  the  same  time,  or  at  least  on  the  same 
week  end,  particularly  since  many  stations  operate  on  the 
National  Calling  and  Emergency  Frequencies  during  that 
week  end  for  the  specific  purpose  of  assisting  in  the  handling 
of  traffic. 

Only  a  few  stations  copied  the  Test  Emergency  Alert  last 
year.  It  was  sent  only  once,  by  WIAW.  This  year,  we  hope 
to  have  WIAW  repeat  it  several  times,  and  perhaps  have 
stations  in  the  Midwest  and  Far  West  send  it  at  unspecified 
times  also.  In  any  event,  we'll  have  TEA  in  this  year's  SET. 
Watch  for  the  details  in  the  announcement,  October  QST. 

W6PKI  reports  that  on  May  7th  the  only  medical  man  on 
Falalop  Island,  a  pharmacist's  mate,  was  seriously  injured 
when  struck  by  a  military  vehicle,  and  aid  was  summoned 
by  amateur  radio.  Ed  Pitta,  operator  of  KC6CG,  made  con- 
tact with  KA3MD  in  Japan  who  immediately  got  ad%ace 
from  military  doctors  which  enabled  him,  with  the  aid  of  a 
native  girl  nurse,  to  do  the  things  necessary  to  save  the 
victim's  life.  KA3MD  then  contacted  KG6AA,  operated  by 
Capt.  Comstock  on  Guam,  who  instigated  an  emergency  air 
flight  to  Falalop  to  evacuate  the  injured  man.  Military  doc- 
tors credit  Ed  Pitta,  KC6CG,  with  saving  the  man's  life  by 
his  prompt  action  in  getting  medical  ad\ice. 

The  AREC  10  Meter  Net  of  Nassau  County,  L.  I., 
held  their  first  hidden-transmitter  hunt  on  January  6th. 
W2KCW/m  was  the  hidden  transmitter  at  a  spot  where 
Hewlett  Bay  almost  surrounded  him.  Four  fixed  stations.

with  the  help  of  beams  and  W2ZJB  with  a  loop,  made  a  fix, 
plotted  it  on  a  map  and  directed  the  twelve  mobiles  to  the 
location.  Within  the  "fix"  area  of  one  square  mile  the  gang 
had  to  drive  up  and  down  the  various  canal  roads  until  the 
correct  one  was  found.  K2AMN's  mobile  loop  proved  so 
good  that  most  of  the  mobiles  are  planning  to  install  one.

An  emergency  drill  called  the  "  Hia-Springs "  drill  was 
conducted  by  the  Dade  County  AREC  starting  at  1400  EST 
on  Feb.  27th.  EC  W4IYT  alerted  the  AREC  and  Dade 
Emergency  Net.  Emergency  net  control  stations  were  set 
up  at  the  Hialeah  Fire  Department  and  at  City  Hall  in 
Miami  Springs.  Mobile  roll  call  began  at  1405,  and  twelve 
mobiles  responded,  nine  of  which  were  dispatched  to 
"bombed"  bridges,  others  kept  on  stand-by.  Each  mobile, 
upon  arri\'ing  at  destination,  dispatched  a  damage  report  in 
standard  ARRL  form,  after  which  they  were  redispatched 
to  specified  councilmen  in  Miami  Springs,  many  of  whom 
rode  along  in  mobiles  during  much  of  the  drill.  After  disaster 
traffic  had  been  cleared,  W4NVU  took  net  control  to  contact 
all  fixed  stations  wishing  to  take  part  throughout  the  coun- 
try, and  five  additional  stations  did  so. 

A  recording  was  made  of  the  whole  operation,  to  be 
played  back  later  and  checked  for  mistakes  in  procedure. 
Publicity  was  given  by  both  the  Miami  Herald  and  the 
Miami  Daily  News.  The  drill  was  secured  at  1600  EST.

The  Tennessee  SEC,  W4RRV,  conducted  a  sectionwide 
surprise  drill  on  April  21st,  to  determine  how  quickly  the 
state-wide  AREC  could  mobiUze  if  necessary.  The  drill  was 
opened  at  1800  EST  and  terminated  at  1924.  W4RRV  says 
that  cooperation  was  wonderful,  and  that  when  the  boys 
called  in,  they  stood  by.  The  drill  was  conducted  on  3980  and

3635  kc,  and  some  local  acti\-ities  were  reported  on  both  ten 
and  two  meters.  A  total  of  65  stations  checked  in  on  3980 
kc,  six  on  3635  and  fourteen  out-of-state,  including  stations 
from  Virginia,  Alabama,  Mississippi,  Kentucky  and  Geor- 
gia. Alabama  SEC  W4TKL  said  he  would  have  activated 
his  extensive  Alabama  AREC  establishment  if  it  had  been  a 
real  emergency.  SCM  W4SCF  and  PAM  W4PFP  were  both 
active. 

Local  nets  were  abo  activated  throughout  the  state.  In 
Nash\'ille,  EC  W40EZ  alerted  his  AREC  gang  after  getting 
word  of  the  surprise  drill  at  1820  CST.  Ten  stations  reported 
into  the  two-meter  net,  which  was  turned  loose  at  1910.  On 
ten  meters,  sixteen  stations  reported  between  1842  and  1855. 
All  this  was  completely  without  any  advance  notice  that  a 
drill  was  to  be  held. 

We  think  the  Tennessee  boys  deserve  a  big  hand  for  this 
spontaneous  demonstration  of  their  readiness. 

The  Communications  Section  of  the  Third  Mobile  Sup- 
port Group,  supported  by  members  of  the  New  Albany 
(Ind.)  Mike  and  Key  Club,  gave  a  communications  demon- 
stration to  the  chiefs  of  the  20  volunteer  fire  departments  of 
Jefferson  County,  Ky.,  on  Monday,  May  16th.  The  exercise 


was  designed  to  give  training  to  the  members  of  the  com- 
munications section  and  to  acquaint  the  fire  people  with  the 
eapabihties  and  Umitations,  and  to  give  them  a  general 
knowledge  of  communications,  equipment  and  personnel; 
also  to  show  them  how  properly  to  word  messages,  which 
were  then  transmitted  from  the  president  of  their  association 
to  the  various  chiefs.  Replies  came  through  in  most  cases. 
The  test  was  quite  successful.  The  communications  picture 
in  Louisville  is  shaping  up  right  nicely.

Seventeen  ECs,  representing  5710  AREC  members,  sub- 
mitted reports  for  May  activities.  This  represents  an  in- 
crease of  seven  reports  from  last  year's  mark,  and  over  3000 
AREC  members  represented.  An  encouraging  sign  of  prog- 
ress, we'd  say.  The  following  sections  reported,  tlirough 
their  SECs  (new  sections  for  the  year  in  italics) :  Ontario, 
Western  N.  Y.,  Western  Fla.,  Maine,  South  Dakota, 
Montana,  Alabama,  Los  Angeles,  West  Va.,  Minnesota, 
N.  Y.  C.-L.  L,  Oregon,  San  Joaquin  Valley,  Eastern  Fla., 
Nebraska,  \\'isconsin,  Washington.  Twenty-si.\  sections  have 
reported  in  1955,  only  six  below  last  year's  total.  Midyear

RACES  News 

Some  time  ago  we  received  a  very  fine  article  from 
W6JAL'  on  the  Arcadia,  Calif.,  civil  defense  emergency 
radio  set-up.  W6JAU  is  not  only  EC  for 
Arcadia,  but  also  communications  chair- 
man for  the  Arcadia  Red  Cross  Disaster 
Corps  and  radio  officer  for  Civil  Defense 
Area  D.  In  Arcadia,  civil  defense  and 
Red  Cross  work  hand-in-hand  with  the 
AREC  to  form  a  closely-knit  organiza- 
tion to  provide  any  kind  of  emergency 
communications  called  for.  They  have 
14  mobiles,  two  pack  sets  and  one  hand-carried  unit,  two 
gasoline-driven  generators  and  necessary  fixed  station  equip- 
ment to  set  up  a  net  control  station  anywhere  in  a  matter 
of  minutes.  Mobility  and  versatility  of  equipment  are  para- 
mount in  Arcadia.  The  fixed  net  control  is  K6AQT,  located 
in  the  basement  of  the  City  Hall.  Vertical  polarization  is  used 
by  all  units  to  facilitate  mobile  work. 

Arcadia,  being  the  control  center  headquarters  for  Civil 
Defense  Area  D,  has  the  responsibility  of  coordinating 
eleven  cities  in  its  area,  some  of  which  have  similar  mobile 
nets  of  their  own.  Those  which  do  not  are  served  by  the 
Arcadia  group  or  that  of  a  near-by  or  adjacent  city.  The 
Arcadia  group  meets  each  month  and  conducts  frequent  net 
drills  and  demonstrations.  All  members  have  Red  Cross  and 
civil  defense  identification,  including  RACES  clearances. 
The  group  even  has  a  TVI  Committee. 

A  salute  to  Arcadia  and  its  well-organized  establishment 
of  amateurs  serving  civil  defense  and  the  Red  Cross! 

Recent  reports  from  the  City  of  Baltimore  indicate  a 
healthy  increase  in  interest  and  activity  among  the  RACES 
group.  In  addition  to  participation  in  "Operation  Alert" 
(see  summary  elsewhere  in  this  issue  of  QST),  a  city-wide 
radio  alert  is  held  the  tliird  Friday  of  each  month,  with  six 
rigs  each  putting  30  watts  into  a  ground-plane  antenna  on 
145-147  Mc,  working  from  1930  to  2130  EDST  and  working 
into  120  field  units. 

These  alerts  and  practice  drills  pay  off,  interest-wise, 
training- wise  and  civil  defense- wise.  Join  your  RACES  group

1955  FIELD  DAY  NOTE 

Field  Day  High  Claimed  Scores  will  appear  in  October 
instead  of  September  QST  due  to  the  later  scheduling  of 
the  contest  this  year. 

TRAFFIC  TOPICS 

On  the  first  day  of  August,  we  put  all  present  net  registra- 
tion file  cards  behind  a  tab  marked  "Inactive  Nets."  Since 
then,  nets  reregistered,  or  new  nets  registered,  have  been 
transferred  to  the  "Active  Nets"  tab.  This  is  regular  prac- 
tice in  our  net  registration  department.  August  1st  is  the 
renewal  date.  September  QST  makes  the  announcement. 
November  QST  carries  the  first  net  list,  followed  by  sup- 
plementary lists  in  QSTs  for  Januarj',  March  and  May.  The 
complete,  multilithed  net  directory  comes  out  in  December. 

Each  year  we  try  to  aim  at  getting  nets  reregistered  a 
little  earlier,  but  so  far  we  haven't  been  making  it.  One  big 
reason  for  this  is  that  compiling  and  maintaining  the  direc- 
tory is  a  stupendous  job  requiring  a  lot  of  someone's  time; 
then  it  must  be  cliecked,  rechecked  and  cross-checked  before 
it  can  be  reduced  to  lithograph  process.  After  that,  it  must 
be  shepherded  tlirough  the  lithographing  room  and  mail 
room  in  competition  with  regular  bulletins  like  the  CD 
Bulletin,  LO  Bulletin,  Club  Bulletins,  'Phone  Bulletins, 
Bidletins  about  Bulletins,  etc.  ad  infinitum.  And  because  the 
Net  Directory  is  somewhat  voluminous,  and  getting  more 
so  each  year,  it  is  often  by-passed  to  get  at  other  bulletins 
which  carry  mailing  suspense  dates. 

Each  of  you  can  help  by  getting  your  net  registered  early. 
This  year,  we'd  like  to  start  putting  together  the  litho  net 
directory  around  the  first  of  November,  have  it  completed 
by  mid-November  and  in  the  mail  by  December  Ist.  We 
can't  do  this  unless  you  cooperate  by  registering  or  re- 
registering now,  and  make  it  a  standard  practice  on  some- 
one's part  to  keep  that  registration  up  to  date  immediately 
any  changes  are  made. 

We  have  registration  cards  (Form  CD-85)  available  upon 
request.  They're  the  same  as  last  year's,  and  have  space  for 
the  following  information:  (1)  Name  of  Net;  please  adopt  an 
official  name  and  stick  to  it.  (2)  Net  Designation,  if  any; 
most  c.w.  nets  have  designations  and  some  'phone  nets  have, 
such  as  EAN,  TCPN,  etc.  (3)  Frequency  (or  -ies);  give  the 
exact  frequency,  not  just  the  band.  (4)  Days;  tell  us  which 
days,  not  how  many;  "daily"  means  every  day,  including 
Sunday.  (5)  Manager;  the  guy  who  runs  the  net,  called 
NCS  on  some  nets;  what  we  want  is  the  call  of  the  head  man 
on  the  net,  to  whom  any  correspondence  can  be  directed. 
(6)  Time  the  net  starts  and  time  it  ends;  please  use  standard 
time,  and  be  sure  to  indicate  which  time  zone.  (7)  Direct 
Coverage;  area  covered  by  regular  net  members,  not  through 
liaisons  wth  other  nets.  (8)  Purpose  of  net;  this  year,  we're 
not  registering  social,  or  rag-chew  nets,  but  only  those  with 
an  emergency  or  traffic  purpose.  (9)  Starting  Date;  if  an  old 
date,  give  the  year;  if  a  new  one,  the  month  and  year.  (10) 
N^et  Control  Stations;  list  them;  they  go  on  our  NCS  mailing 
list  to  receive  Emergency  and  Traffic  Bulletins.  (11)  NTS; 
indicate  whether  or  not  the  net  is  affiliated  with  the  Na- 
tional Traffic  System.  (12)  Liaisons;  list  the  nets  with  which 
regular  liaison  is  conducted.  (13)  Name  and/or  call  of  the 
person  submitting  the  information. 

Most  of  this  information  is  transferred  to  a  regular  net 
file  card.  Original  registration  cards  (the  ones  you  send  in) 
are  kept  on  file  for  a  year,  then  discarded.  Use  of  the  regular 
registration  card  is  not  required,  but  it's  a  convenience  both 
to  you  and  to  us  to  use  it.  If  not  used,  please  give  us  the

National  Traffic  System.  We  seem  to  need  a  small  "shot 
in  the  arm"  about  reporting.  It's  natural  enough  for  net 
reports  to  fall  off  during  the  summer  months,  but  now  that 
NTS  is  an  established  institution  among  organized  traffic 
circles,  we'd  like  to  feel  that  100%  reporting  is  the  cus- 
tomary thing,  not  the  exception.  Can  we  have  a  bit  better 
consistency  in  this  regard,  gang?

A  complete  list  of  NTS  net  managers  at  regional  and 
area  level  may  be  in  order;  it  has  been  quite  some  time  since 
one  was  presented  here: 

Area  Nets:  Eastern  Area  Net  —  W8SCW;  Central  Area 
Net  —  W9JUJ;  Pacific  Area  Net  —  W7APF. 

Regional  Nets:  IRN  — WIBVR;  2RN  — W2LPJ;  3RN 
—  W3NRE;  4RN  — W4BVE;  RN5  — W40GG;  RN6 — 
W6ZRJ;  RN7  — VE7ASR;  8RN  — W8DSX;  9RN — 
W4KKW;  TEN  (Tenth  Regional  Net)— W0DQL;  TRN 
(Thirteenth  Regional  Net)  —  VE3GI.  The  Eleventh  and 
Twelfth  Regional  Nets  have  never  materialized,  being 
originally  intended  for  the  Mountain  Area.  These  nets 
were  absorbed  into  the  Seventh  and  Sixth  Regional  Nets 
respectively  and  report  into  the  Pacific  Area  Net. 

Transcontinental  Corps:  Eastern  Area  Director — ■ 
W8UPB;  Central  Area  Director  —  W9JUJ;  Pacific  Area 
Director  —  W6HC  (until  September  30th). 

Maine  and  W.  Mass.  made  perfect  attendance  in  IRN 
during  June.  W40GG  reports  that  morning  sessions  (0600 
CST,  3645  kc,  Mon.  through  Sat.)  are  still  going  strong. 
RN6  has  good  representation  from  California  sections,  not 
so  good  from  others;  a  very  fine  RN6  Bulletin  was  issued 
in  July.  W9D0  reported  his  eleven  sessions  of  9RN,  and  is 
filUng  in  until  new  manager  W4KKW  takes  hold.  TEN 
conducts  a  session  at  1700  CST  in  addition  to  the  regular 
sessions  at  1945  and  2130.  VE3GI  reports  that  VE2DR 
is  holding  down  Quebec  representation  to  TRN  single 
handed,  that  Maritimes  coverage  is  very  spotty,  and  that 
the  use  of  7070  kc.  has  been  dropped  as  of  August  Ist. 

W6HC  indicates  that  the  following  TCC  stations  sub- 
mitted reports  for  June:  W0KQD,  W7CCL,  K6BDF, 
W6ADB,  VE7QC,  K0WBB,  W6IPW.  Total  traffic  reported 
amounted  to  189.  Many  TCC  stations  are  off  for  vacations. 
W6HC  announces  his  resignation  as  TCC  Director  effective 
September  30th  due  to  the  pressure  of  other  business.

HOBBY  SURVEY 

In  a  recent  ARRL  field  organization  survey  asking  about 
"any  other  hobbies"  and  "your  favorite  contest,"  answers 
came  from  all  classes  of  appointees.  Results  apply  in  the 
main  to  the  field  organization  group,  of  course.  The  typical 
appointee-operator  has  an  input  of  236  watts  and  operates 
43  hours  per  month.  His  interest  in  broad  terms  shapes  up 
as  follows;  30%  traffic,  30%,  rag  chewing.  22.3%  DX,  17.7% 
construction. 

Favorite  contest?  Looking  at  the  "big  four"  in  ARRL 
affairs  it  came  out  like  this:  SS  40.4%,  FD  31.9%,  DX 
Competition  19%,  V.H.F.  SS  8.7%.  The  one  favorite  band? 
80  got  68%  of  the  votes,  40  got  15%.  Looked  at  from  the 
standpoint  of  all-band  use  the  bands  looked  as  follows:  160 
2.2%,,  80  38.7%,  40  20.5%,  20  18%,  15  5%,  11  .4%,  10 
6.6%,  6  1.7%,  2-and-above  6.9%.  Half  the  gang  used  two 
favorite  bands  most  of  the  time.  Over  a  quarter  of  the  gang 
have  just  one  favorite  band.  Few  use  over  three  bands.  25% 
had  emergency  power  for  a  home  emergency  station;  37% 
had  mobiles.  Answers  about  interests  included  such  ex- 
pressions as  "What  other  hobby  could  there  be?"  "Are  you 
kidding?"  "Who  could  afford  another?"  "No  favorite  con- 
test, I  love  'em  all."  20%  insisted  there  could  be  no  other 
hobby  interest  than  amateur  radio.  But  this  group  was  out- 
numbered by  those  with  other  interests. 

It  is  said  that  a  man  is  fully  alive  only  in  proportion  to  his 
interests.  There  is  a  lot  in  that  view  but  we  amateurs  have 
very  little  to  worry  about  ...  to  judge  from  the  survey  of 
other  hobbies.  We  found  over  100  hobbies  listed  by  name! 
No  indication  of  hobby-time  for  these  other  things  was  indi- 
cated. However,  a  variety  in  interests,  the  balanced  life  our 
Amateur  Code  indicates  is  by  most  standards  rich  in  the 
things  that  make  for  contrast  and  triumphant  living  values. 
Seventy  percent  of  our  gang  engage  in  five  most  popular 
additional  hobbies  among  the  one  hundred:  (1)  photog- 
raphy 32%;  (2)  fishing  9.7%;  (3)  music  7%;  (4)  stamps 6.6%; 
(5)  hi-fi  5.8%.  Others  run  the  gamut  from  bird  watching  and 
skin  diving  to  breeding  peonies,  raising  parakeets,  canaries, 
tropical  fish,  dogs,  keeping  bees  and  building  models. 
There's  hardly  anything  amateurs  don't  do  wlien  it  comes  to 
other  hobbies,  too!

MARYLAND  DELAWARE-DISTRICT  OF  COLUM- 
BIA—SCM,  John  W.  Gore,  W3PRL  —  From  the  view- 
point of  the  SCM's  visits  to  the  many  areas  within  the 
section,  and  also  reports,  and  despite  the  inclement  weather 
Saturday  afternoon  and  night,  which  did  not  seem  to 
dampen  the  ardor  or  enthusiasm,  this  section  should  in  the 
final  analysis  show  exceptional  results  in  the  Field  Day 
Contest.  Operation  Alert  resulted  in  considerable  activity 
by  amateur  groups;  typical  examples  being  the  Hagerstown 
group  with  OYX,  OXL,  JVZ,  TJV,  and  YRK  on  the  local 
net  frequency  of  3827  kc.  tying  into  State  C.D.  Head- 
quarters on  3820  kc,  and  St.  Mary's  group  with  BUD  at 
C.D.  Headquarters  at  Leonardtown  handling  the  local  net, 
consisting  of  ADQ,  PPY,  AVL,  and  ZZK,  who  operated 
both  fixed  and  mobile.  ZZK  and  AVL  also  relayed  traffic  via 
2  meters  to  N3ZYB  in  Calvert  County.  The  Governor  hav- 
ing proclaimed  the  week  of  June  19-25th  as  "Radio  Amateur 
Week,"  it  was  decided  that  it  would  be  appropriate  to 
hold  a  Victory  Dinner  in  celebration  of  the  signing  of 
the  Maryland  License  Plate  Bill.  This  dinner  was  held 
June  22nd  at  the  Park  Plaza  where  those  who  were  active 
in  securing  backing  for  the  Bill,  as  well  as  Senator  Demp- 
sey  of  the  Legislature  and  other  guests,  were  present. 
CARC  members  NH,  UYJ,  LZZ,  BYG,  CJN,  and  KOU 
totalled  1064  points  in  the  1955  V.H.F.  QSO  Party  on  2 
meters.  The  Harford  County  C.D.  Net  is  rapidly  progress- 
ing in  both  attendance  at  regular  drills  and  installation  of 


equipment  at  the  ocal  headquarters  at  Bel  Air.  Those 
participating  regularly  are  8CPN/m3,  K2GDH/m3,  LDD/- 
m3,  0MZN/m3,  0OKI/m3,  and  /3,  9QOI/m3  and  /3, 
RMY/3,  SZY/3,  UCR/3,  2YAY/m3,  and  5ZOG/3  and 
/m3.  The  V.H.F.  Contest  of  June  11-12  found  CIQ  and 
RAH  operating  at  Gambrill  State  Park  under  CIQ,  where 
they  worked  101  stations  in  6  sections.  BNC,  EPV,  and 
VAM  operated  from  their  own  QTH  in  the  Hagerstown 
section.  The  Hagerstown  group  mustered  20  members 
participating  full  time,  with  others  helping  during  their 
available  hours  during  Field  Day,  and  over  800  contacts 
were  made.  ECU  has  completed  his  813  final  and  will 
operate  on  40  and  20  meters.  MCQ  has  acquired  a  5-kw. 
gas-engine  generator  for  emergency  use  after  he  returns  from 
a  month's  trip  to  New  Mexico.  WV  reports  unexpected  level 
of  acti^^ty  on  the  MDD  Net  during  the  early  part  of  the 
period.  HKS  has  a  Viking  Ranger.  WG  surprised  himself 
with  the  operation  of  his  4-watt  brief-case  portable  on  75- 
meter  C.W.  and  'phone.  RV  reports  the  Andrews  Air  Force 
Base  Wind  Bag  Net  now  is  operating  on  7240  kc.  The  Radio 
Engineers  Club  of  CREI  in  Washington  is  on  the  air  with 
a  kw.  and  the  club  call  YXM.  EQK  probably  has  reported 
from  more  remote  locations  by  mobile  into  the  MEPN  than 
any  other  member.  His  latest  accomplishment  was  to  report 
in  on  his  marine  mobile  from  the  upper  Chesapeake  Bay. 
AVL  and  BH  have  operated  on  the  air  with  s.s.b.  YYB  and 
YYF,  George  and  Merle,  a  father-and-son  combination, 
completed  their  10-meter  beam  on  July  4th  and  are  looking 
forward  to  highly  increased  activity.  Their  first  contacts 
on  the  new  beam  were  with  stations  in  Bermuda  and  Puerto 
Rico.  PGB  is  back  on  the  air  after  a  delayed  recovery  from 
"Hazel."  Traffic:  (June)  W3WG  1130,  WV  515,  UE  112,

{JVo.  8  of  a  Series} 


/n  February  of  this  year  we  made 
our  first  appearance  on  this  page.  In 
the  intervening  months  we  have  tried 
through  this  means  to  open  the  doors 
of  HaUicrafters  engineering  laboratories 
to  thousands  of  hams  throughout  the 
world.  We  hope  we  have  been  of  service  to  you  in  the  growing  field  of 
single  sideband  with  articles  on  receivers,  exciters  and  amplifiers.  As 
the  world's  largest  manufacturer  of  ham  equipment,  we  will  continue 
to  cover  these  and  other  technical  subjects  in  the  future. 

^UT  let's  look  back  for  a  moment  on  what  has  happened  in  the  way 
of  product  development  since  February.  We  introduced  the  SX-96 
with  selectable  sideband  which  promises  to  be  the  most  popular 
medium  priced  receiver  ever  produced.  In  recent  months  the  HT-31 
linear  amplifier  made  its  appearance,  giving  "talk  power"  equivalent 
to  a  kilowatt  of  AM  in  a  compact,  table-top  package. 

^THER  new  and  exciting  products  have  been  engineered  for  you,  the 
hams. 

/Tn  extremely  stable  filter-type  AM-CW-SSB  transmitter/exciter 
(model  HT-30)  will  be  available  soon.  A  new  receiver  (model  SX-100) 
incorporating  the  highlights  of  the  SX-96  —  and  then  some  —  is  in 
production.  A  complete,  highly  styled  console  made  up  of  the  HT-30, 
HT-31  and  SX-100  —  ready  to  operate  —  is  planned  for  later  this  fall. 

/mmediately  available  for  ham,  novice  and  short-wave  listeners  are 
popular  receivers  like  the  S-38D,  S-53A,  S-85,  SX-99  and  SX-62A. 
For  industrial,  emergency  and  Civil  Defense  use  we  have  the  low 
cost  S-94  and  S-95  FM  receivers  as  well  as  our  deluxe  "Littlefone" 
two-way  radio  telephones. 

/he  parade  of  new  products  will  continue  in  1956;  but  in  this  brief 
report  we  wanted  to  keep  you  posted  on  our  plans  for  the  immediate 
months  to  come.  We  hope  that  your  plans  will  include  HaUicrafters 
equipment.

Ideal  trimmer 
for  VHF  range 

To  keep  pace  with  the  continuing  efforts  of 
the  electronic  industry  toward  miniaturiza- 
tion of  components,  Hammarlund  has  intro- 
duced a  tiny  variable  capacitor,  type  "MAC". 
This  component  provides  the  low  minimum 
capacity  essential  for  use  as  a  trimmer  in 
the  VHF  range. 

The  silicone-treated  base  is  only  ^  x  % 
inches.  Its  rotor  and  stator  are  soldered  as- 
semblies of  brass,  nickel-plated  for  low  losses, 
while  the  wiper  rotor  contact  is  nickel-plated 
beryllium-copper.  Rotor  and  stator  terminals 
are  positioned  to  permit  short  leads. 
A  threaded  bearing  is  provided  with  flat 
sides  to  permit  single-hole  moimting  without 
turning. 

The  new  units  are  available  to  fulfill  capacity 
requirements  between  1.4  and  19.6  mmf.  Try 
one  in  your  next  piece  of  gear.

\fter  three  years  engineering  and  design  f/me  •  • . 


Three  years  ago,  Hammarlund  set  out  to  design 
and  build  an  amateur  receiver  that  would 
provide  absolutely  the  last  word  in  perform- 
ance. And  here  it  is  — the  NEW  Pro-310. 

This  rig  was  designed  with  performance  in 
mind.  We've  not  cut  corners.  Frequency  read- 
ings can  be  read  to  1  part  in  5000;  the  band- 
spread  can  be  continuously  calibrated  over  the 
entire  range;  it  is  exceptionally  stable;  construc- 
tion is  sectionalized;   and   many  other  features 


are  built  in  to  give  one  thing  — top  performance. 
If  you've  longed  for  a  receiver  that's  as 
modern  as  this  minute,  you  want  a  new  Pro-310. 
Look  it  over  at  your  dealers'.  If  he  doesn't  have 
one  now,  he'll  be  getting  his  stock  soon.  Get 
specs  and  other  information  either  from  him  or

MODULATION  8  MAXIMUM  POWER 


A  peak  in  the  response  curve  limits 
modulation  to  the  peak  value.  A  peak-free 
response  brings  the  full  power  level  to 
100%  modulation  gaining  an  intelligibility 
increase  equal  to  the  peak  in  the  average 
mike.  The  664  is  peak-free  and  gives  the 
highest  usable  pov^er  of  any  microphone 
for  AM,  NFM  and  SSB. 

See  your  E-V  Distributor, 

or  write  for  Specification  Sheet 


The  664  will  equal  a  useful  power  increase 
of  four  times  over  commonly-used  peaked 
microphones,  and  could  well  be  the  best 
investment,  dollar-wise,  in  your  shack 

Here  is  a  totally  new  concept  in  microphones  for 
amateur  phone  communication. 

The  cardioid  (high  directivity  at  all  frequencies) 
pickup  pattern  enables  you  to  have  a  real  "arm  chair 
QSO."  The  forward  gain  of  5  db**  allows  you  to  speak 
at  nearly  twice  the  distance  you  have  been  working  to 
a  conventional  microphone.  Unwanted  sounds  in  the 
shack  are  rejected  nearly  twice  as  effectively  as  by 
ordinarily-used  non-directional  microphones. 
The  response  curve  is  tailored  to  put  the  highest 
degree  of  intelUgibility  on  your  carrier.  Your  100% 
modulation  is  all  speech  ...  in  full  character  .  .  .with 
bite  and  punch.  This  curve,  compared  to  ordinary 
microphones,  will  give  you  up  to  12  db  more  usable 
audio — without  splatter  or  hash. 

We  invite  you  to  prove  to  yourself  that  the  664  will 
outperform  your  present  mike  by  a  direct  comparison. 
If  it  doesn't  out-hurdle  QRM,  your  distributor  will 
refund  the  purchase  price  without  qualification. 

New  Variable  D*  Dynamic  Microphone  operates  on  the  prin- 
ciple of  multiple  sound  paths  to  the  diaphragm.  Spaced 
apertures  to  the  rear  of  the  diaphragm  are  phased  to  pro- 
vide cancellation  of  rear  sounds  and  give  full  response  to 
sound  from  the  front. 

This  new  principle  enables  the  curve  to  be  free  from  peaks 
or  dips.  Insures  freedom  of  blasting  and  boominess  from 
close  talking.  Eliminates  effect  from  mechanical  shock. 
High  level  -55  db.  Acoustalloy  diaphragm.  Switch  easily 
changed  to  relay  control,  if  desired.  Absolutely  unaffected 
by  moisture,  humidity,  or  temperature. 

Model  664.  Without  Stand Net  Price:  $47.70 

Model  419.  Desk  Stand Net:      9.00 


**Forward  gain  is  that  compared  to  a 
pressure  mike;  actual  front-to-back 
hemisphiere  pick-up  ratio  is  20  db.

KENTUCKY  — SCM,  Robert  E.  Fields,  VV4SBI — 
SEC:  CDA.  RM:  KKW.  Acting  PAM:  NIZ.  A  large  num- 
ber of  the  Kentucky  amateurs  turned  out  for  Field  Day,  the 
clubs  turning  in  the  liighcst  scores  and  having  the  highest 
number  of  operators.  Several  Field  Day  messages  were  sent 


to  the  SCM  for  a  twenty-five  (25)  point  credit.  It  sure  is 
good  to  see  so  many  working  their  gear  with  emergency 
power  and  operating  conditions.  Our  next  big  day  is  the 
Lexington  Hamfest  Sept.  25th.  CDA  suggests  that  all 
Kentucky  stations  obtain  copies  of  the  ARRL  Operating 
Manual  and  Emergency  Communications  Manual,  free  to 
.\RRL  members  on  request  from  either  CDA  or  SBI. 
WNH  is  planning  a  300-watt  final  for  2  meters.  SBI  now 
has  an  antenna  up  for  80  meters  and  hopes  that  it  will  work 
across  the  state  line  at  least  and  also  hopes  to  have  a  pair 
of  813s  on  before  too  long.  Jl'I  says  he  has  a  13-year-old

Asst.  SCMs:  Joe  Beljan,  8SCW  (c.w.);  Bob  Cooper,  8AQA 
Cphone).  SEC:  GJH.  A:tivitiesseem  to  have  hit  the  summer 
slump  after  a  successful  Field  Day.  Conditions  have  taken 
a  toll  on  the  traffic  nets  and  the  hot  weather  seems  to  have 
driven  most  of  us  outside.  Judging  from  the  Field  Day 
activity  noticed,  there  should  be  some  new  records  this  year. 
Despite  the  odds,  many  of  the  emergency  nets  seem  to  be 
functioning  through  the  summer  months  as  they  well  should. 
There  is  no  new  word  from  the  SEC  this  month,  but  I  am 
assured  that  he  is  continuing  to  work  with  the  MOCD  offi- 
cials as  mentioned  in  tlie  last  report.  FGB  reports  that  the 
call  KQ.4A4  has  been  issued  as  a  "Disaster  Communications 
Service"  for  the  St.  Joseph-Benton  Harbor  Area  and 
will  be  operated  by  Ground  Observer  Corps  personnel.  This 
station  will  use  1761.5  kc.  (Ch.  9)  and  1782.5  kc.  (Ch.  12) 
for  fixed  and  mobile  work.  This  is  the  second  such  station 
authorization  granted  in  Michigan.  More  details  may  be 
obtained  from  FGB.  New  officers  ('55-'56)  of  the  Catalpa 
Amateur  Radio  Society  are:  WD,  pres. ;  GBT,  vice-pres. ; 
UEO,  rec.  secy.;  ELR,  corr.  secy,  and  treas.  JKX  says  he 
needs  some  good  dope  on  an  80-meter  vertical  antenna. 
Sounds  like  he  is  penned  in.  Anybody  have  any  ideas  for 
him?  QIT  sent  some  pictures  of  liis  neat  basement  shack 
and  his  magnesium  three-element  wide-spaced  20-meter 
rotary  that  weighs  only  90  pounds.  He  should  be  ready  for 
the  DX  openings  that  are  starting.  DUS  is  going  after  the 
DX  business  in  an  S-9  manner.  He  is  charting  the  CRPL 
information  about  two  months  in  advance  and  it  is  most 
interesting  to  note  the  accuracy  of  the  predictions.  His 
stacked  10-,  1.5-,  and  20-meter  beams  above  the  120  feet 
of  tower  will  be  there  when  the  times  are  right.  PRL  is 
eager  to  become  active  again  and  solicits  word  from  those 
having  good  equipment  available  for  sale.  Traffic:  (June)

AUTOMATIC  T  -  R  ANTENNA  SWITCH 

Fully  automatic  electronic  antenna 
changeover  from  receiver  to  transmitter 
and  vice-versa.  Suitable  for  all  powers 
up  to  legal  limit.  Ideal  for  voice  operated 
SSB — AM  phone  and  break-in  CW--all 
with  one  antenna  .  .  .  ending  annoying 
antenna  changeover  relay  clatter.  You 
can  automatically  select  one  antenna  for 
receiving  and  transmitting,  getting  an 
actual  receiving  signal  gain  from  1  mc 
to  35  mc.  Because  the  Model  380  is 
broad  band,  there's  no  tuning  or  adjust- 
ments to  make,  and  as  a  fail-safe  device, 
it  protects  your  final  amplifier,  low-pass 
filter,  etc.  Power  loss  on  transmission 
is  almost  unmeasurable.  Operates  with 
either  52  or  75  ohm  coax  line.

1  with  this  new  B&W 
low  pass  filter.  Wave 
Guide  principle  and 
novel  multi-sectional 
construction  mean  more 
attenuation  in  less  space 
at  lower  cost. 


ALL  OF  THESE  FINE  B&W 
products  are  available  at  leading 
distributors' everywhere.

VN.J  and  OBU  operated  from  the  Statler  Hotel  handling 
traffic  for  the  VValther  League  Convention.  K2HYK's 
antennas  are  up  an  extra  few  feet  to  help  his  traffic  count 
go  higher,  too.  Many  of  our  stations  enjoyed  vacation  trips 
with  ham  radio  gear  accompanying  them.  .JCJV/1  made  a

NKD,  and  CGG.  The  Irvington  Radio  Amateur  Club  has 
suspended  activities  for  the  summer  season.  CVW  now  is 
settled  in  his  new  QTH,  and  hopes  to  become  more  active 
again.  DRV  finds  that  time  slips  by  very  rapidly  and  sends 
in  a  five-month  traffic  re|)ort  covering  the  period  February 
to  .Jime.  We  will  list  the  total  of  62  in  this  part  of  the  column 
to  eliminate  confusion.  Thanks,  Bob,  even  if  it  is  late  we 
appreciate  it.  KN2KHZ  now  is  K2KHZ,  having  passed  the 
General  Class  exam  on  ,J\ily  6th.  Congrats,  Dave.  He  was 
very  active  in  DX  work  while  a  Novice,  running  up  a 
total  of  which  to  be  very  proud.  The  1.5-w.p.ni.  CP  did  the 
trick  for  Dave  and  helped  him  on  to  the  new  ticket.  As  a 
further  reward  the  XYL  has  presented  him  with  a  new  jr. 
operator,  David  Alan.  K2HXP  has  a  6146  rig  on  the  way. 
K2GLS  partieipated  in  his  first  Field  Day  and  was  very 


favorably  impressed.   EFJ  won  the  Ir\'ington  RC  hidden 

transmitter  hunt.  The  "booby"  prize  went  to  WFK  who, 
according  to  reports,  had  to  be  roped  into  the  site.  Many 
activity  reports  have  been  received  on  Field  Day  activities. 
K2GAS  is  in  bad  shape;  he  is  on  with  the  six- watt  exciter 
fighting  the  QRM.  K2GAN  and  K2BFE  are  organizing  a 
civil  defense  communications  net  for  New  Providence.  A 
remarkable  Field  Day  job  was  done  by  VAV  and  H.JD. 
They  joined  together  as  a  team  and  with  a  30-watt  trans- 
mitter worked  right  on  through  the  entire  contest  period. 
The  heavy  rains  slowed  them  down  a  bit,  but  never  was  the 
rig  silent.  A  special  Field  Day  QSL  card  is  the  reward  for 
any  station  working  them.  In  fact,  the  cards  come  in  two 
designs  and  are  sure  FB.  A  great  deal  of  credit  goes  to  these 
two  fellows  who  have  the  real  old-fashioned  Field  Day 
spirit.  K2BWQ  has  a  new  75A-4.  The  KWSl  has  not  been 
delivered  as  yet.  K2ELTN  has  left  for  Northern  Texas.  Drop 
a  line  to  the  local  SCM  (page  6  QST)  for  a  transfer  of  your

A  PAIR   OF  EIIVIAC   aX250B'3- 

the  easy,  modern  approach 
to  a  compact  one-kilowatt  CW  and  SSB  rig 


You'd  be  amazed  how  easy  it  is  fo  build  a  one- 
kilowatt  rig  using  Eimac  4X250B  radial-beam  power 
tetrodes.  Each  of  these  bantam  lubes  handles  500 
watts  input  with  only  2000  volts  on  the  plate. 
A  pair  in  the  final  amplifier  provides  a  kilowatt 
with  the  power  supply  and  transmitter  combined 
taking  only  a  fraction  of  the  space  required  for  ar» 
old-fashioned    kilowatt  rack. 

The  straight  forward  modern  approach  afforded  by 
4X250B's  allows  simple  circuit  design.  Driving  power 
is  so  low  that  annoying  TVI-producing  harmonics 
generated  in  the  driver  stages  are  minimized.  Low 
feedback  capacitance  makes  stabilization  of  the 
amplifier  stage  easy. 

The  versatile  4X250B  can  supplant  the  famous 
4X1 50A,  and  it  offers  the  advantages  of  easier 
cooling  and  higher  power.  No  forced-air  cooling  is 
required  during  stand-by  periods  if  convection  air 
is   provided   properly. 

For  further  information  on  the  new  4X250B,  contact 
our  Amateur  Service  Bureau  or  visit  your  Eimac 
distributor.

ALASKA  — SCM,  Dave  A.  Fulton,  KL7AGU  —  The 
CD.  Test  of  June  15th  went  very  well  in  the  Anchorage 
Area  with  a  good  turnout  of  mobiles  as  well  as  a  crew  at  the 
c.d.  headquarters,  which  handled  the  situation  very  well 
as  far  as  comnmnications  were  concerned.  The  mobiles  in 
the  Anchorage  Area  were  called  upon  a  second  time  this 
month  for  aid  in  the  Lions  Club  operation  "Little  Red 
Wagon"  Teletlion.  There  was  a  good  turnout  of  mobiles  on 
this  operation  also,  even  though  it  came  on  the  same  week 
end  as  Field  Day.  There  seems  to  be  quite  a  bit  of  interest 
in  the  Alaskan  DX  certificate.  Maybe  it's  a  little  harder 
to  get  than  we  thought.  No.  1  has  not  been  given  out  as 
yet,  but  we  do  know  of  one  station  just  waiting  for  the  con- 
firmations to  roll  in.  There  were  some  15-meter  openings  to 
the  States  from  the  Anchorage  Area  in  both  June  and  July.

proved  himself  as  a  hard  and  conscientious  worker  for  the 
good  of  his  fellow  hams.  I  feel  sure  that  a  better  choice 
could  not  have  been  made  and  iiope  the  gang  will  give  Ralph 
the  same  splendid  cooperation  that  I  received  during  my 
term  of  office.  Field  Day  once  more  was  the  main  event  of 
June.  From  tlie  reports  received  here,  it  was  equal  to  or 
better  tlian  last  year.  I  received  five  Field  Day  messages, 
whicli  is  tlie  most  yet,  indicating  the  section  was  well  repre- 
sented. FEA  and  WJF  have  moved  to  the  Bay  Area,  but

c.d.  alert  drill  was  a  success.  It  was  the  first  in  Stanislaus 
County  to  use  ham  radio,  and  many  c.d.  officials  were  sur- 
prised to  find  ham  radio  so  efficient.  The  CVRC  Picnic  was 
a  success  and  all  who  attended  enjoyed  themselves.  Maybe 
it  will  be  an  annual  event.  Traffic:  W6TTX  517,  ADB  80,

all  of  the  time.  Mobile  stations  would  like  to  work  also. 
When  you  have  a  sked  on  the  net  freciuency  move  off  the

You'll  like  every  feature 
of  the  New 
MALLORY 
VIBRAPACK 
Power  Supply 


Designing  a  battery-operated  mobile  rig?  For 
the  power  supply,  take  a  look  at  the  features 
that  are  built  into  the  new  Mallory  Vibrapack. 

HEFT  IT — the  Vibrapack  fits  easily  into  the  palm 
of  your  hand.  It's  less  than  53^  inches  in  its 
longest  dimension. 

CHECK  ITS  WEIGHT— it's  barely  4  pounds. 

LOOK  INSIDE— its  sturdy  steel  cover  and  bot- 
tom plate  snap  off  quickly,  without  need  for 
struggling  with  screws  or  complicated  fasteners. 

SEPARATE  TAP  for  the  rectifier  filament  assures 
instant  restart  after  stand-by. 

HOOK  IT  UP— there  is  a  model  for  6,  12  or  24 

volt  operation. 

LOAD  IT  DOWN — each  model  is  conservatively 
rated  to  deliver  the  power  you  need  at  high 
efficiency  and  with  minimum  battery  drain.  One 
model  has  taps  for  either  210  or  260  VDC  at 
60  MA;  another  has  an  output  of  325  VDC  at 
100  MA.  Both  ratings  apply  when  used  with 
rated  input  voltage,  and  working  into  a  mini- 
mum of  10  MFD  input  capacitance. 


TRY  it  with  a  sensitive  receiver.  Its  built-in  Avide 
range  input  and  output  RF  filters  provide  hash- 
free  performance. 

LISTEN  to  its  quiet  operation.  Mechanical  hum 
is  reduced  practically  to  zero  in  the  new  Mallory 
Vibrator  used  in  the  Vibrapack. 

ASK  any  police  radio  engineer  about  the  long 
Hfe  and  dependabiHty  of  its  series-drive,  heavy- 
duty  communications  vibrator  .  .  .  the  same 
components  used  in  police,  taxi  and  utility 
2-way  mobile  gear  everywhere. 

Designed  for  the  economy  minded  amateur  or 
commercial  engineer,  the  new  Vibrapack  gives 
you  a  lot  of  performance  at  modest  cost.  Its 
ruggedness  and  dependability  are  based  on 
principles  developed  by  Mallory  during  more 
than  25  years  of  building  vibrator  power  sup- 
plies for  communications  equipment. 

See  your  local  Mallory  distributor  for  a  first- 
hand look  at  this  new  line  of  power  supplies.  If 
you'd  like  A\Titten  data,  just  drop  us  a  letter.

1955  VIRGINIA  SECTION  QSO  PARTY 
Sunday,  September  11th 

A  QSO  Party,  open  to  all  Virginia  hams,  will  be  held 
between  the  hours  of  8:00  a.m.  and  8:00  p.m.  EST  on  Septem- 
ber 11,  19.55.  Any  band  or  mode  may  be  used,  but  only  one 
QSO  per  station  per  band  (except  for  mobiles)  is  allowed. 

Information  to  be  exchanged  consists  of  Number  of  QSO, 
RS  or  RST  report,  County  in  Virginia,  and  operator's 
"handle."  Example:  W4YYY,  working  W4XXX  for  his 
tenth  contest  QSO,  sends  him  "NR  ID  W4YYY  599 
CL.4RKE  (COUNTY)  IGNATZ."  W4XXX  then  sends  a 
similar  message  in  return. 

Scoring:  Between  General  Class  or  higher  licensees,  score  1 
point  for  each  message  sent  and  for  each  received,  or  a 
maximum  of  2  points  per  contact.  For  each  message  sent 
and  received  where  at  least  one  end  of  the  QSO  is  a  Novice 
(i.e.  Novice  to  Novice,  or  Novice  to  higher  class  licensee), 
score  5  points,  or  a  maximum  of  10  points  per  contact. 
Multiply  total  number  of  contact  points  by  the  number  of 
diferent  stations  worked,  and  multiply  that  in  turn  by  the 
number  of  different  counties,  to  determine  final  score. 

Call  "CQ  VA"  on  c.w.  and  "CQ  Virginia  Section  Party" 
on  'phone.  General  or  higher  class  licensees  should  call  "CQ 
VA  WN"  to  indicate  they  intend  to  listen  within  the  ap- 
propriate Novice  sub-band.  Novices  should  listen  outside 
the  nearest  sub- band  limit  for  calls  from  higher  class  licensees. 

Mobiles  operating  in  more  than  one  county  may  be 
worked  once  in  each  different  county  by  a  fixed  station. 
Similarly,  a  mobile  operating  in  more  than  one  county  may 
count  the  same  fixed  station  as  another  contact  from  each 
new  county. 

Good  rallying  points  include  the  Virginia  Net  frequencies, 
3680  and  3&35  kc. 

Abstracts  of  logs  should  be  mailed  to  SCM  W4KX  not 
later  than  October  1,  1955.

POWERHOUSEI 

Here  is  Penta's  new  PL-6549  beam  pentode, 
a  compact  power  package  which  is  daily  finding 
new  apph'cations  where  reliabih'ty,  high  effi- 
ciency at  low  and  medium  voltages,  low  driving 
power,   and    excellent   linearity   are  required. 

For  r-f  output  of  50  to  250  watts,  or  audio 
output  up  to  325  watts,  the  PL-6549  outclasses 
all  other  transmitting-type  tubes.  The  beam 
pentode  construction  improves  linearity — pro- 
vides distortion-free  high  peak  power  output  in 
audio  or  linear  r-f  amplif.ier  service.

FO-1       PRINTED  CIRCUIT  OSCILLATOR 


For  Generating  Spot  Frequency  Signals  with  Guaranteed  Tolerance 
1000  KC  to  15,000  KC  fundamental  operation 

Since  the  operating  tolerance  of  a  crystal  is  greatly  affected 
by  the  associated  operating  circuit,  the  use  of  the  FO-1  Oscillator 
in  conjunction  with  the  FX-1  Crystal  will  guarantee  close  tolerance 
operation.  Tolerances  as  close  as  .001    percent    can  be  obtained.

FX-1  CRYSTAL  Companion  to  the  FO-1  Oscillator 


The  FX-1  Crystal  is  designed  for  use 
only  with  the  FO-1  Oscillalor.  For  tol- 
erances of  .01  %  and  .005%,  ony  FX-1 
Crystal  can  be  used  with  any  FO-1 
Oscillalor. 


For  tolerances  closer  than  .005*/. 
the  oscillator  and  crystal  must  be  pur- 
chased together.  The  oscillator  is  factory 
wired,  ond  the  crystal  custom  calibrated 
for  the  specific  oscillator.

was,  of  course,  the  West  Gulf  Division  Convention  at  Fort 
Worth,  which  was  excellently  managed  and  had  a  wonderful 
attendance,  giving  many  of  us  a  chance  for  a  QSO  "vi,s-a- 
vis"  with  those  we  had  been  meeting  on  the  air  for  years. 
Many  ciuestions  were  thrashed  out  at  the  various  sectional 
meetings.  The  Bar-B-Q  and  dance  was  well  attended  and 
only  marred  by  the  sudden  death  of  UK.  One  of  the  fine 
things  at  the  Convention  was  tlie  presentation,  in  absentia, 
of  a  scroll  signed  by  the  net  controls  of  the  North  Texas- 
Oklahoma  Traffic  Net  to  PAK  in  recognition  of  his  splendid 
sevices  as  net  manager.  Everyone  who  attended  seemed 
satisfied  that  CF  had  been  elected  Director  of  the  West 
Gulf  Division.  The  Watonga  Ham  Picnic  was  reported  a 
success  by  all.  We  expect  good  results  from  JCB,  new

READ  THIS  AMAZING  LETTER:  How  an  inexpensive  FULL 
SIZE  Gotliam  Rotary  Beam  made  it  possible  to  "worit  the  world!" 


Gotham  ITobby  Corp.  Florida,  1955 

107  East  126th  St.      , 
New  York  35.  N.  Y. 
Gentlemen: 

I'd  like  to  express  my  enthusiasm  and  satisfaction 
regarding  your  20-meter  rotary  beam  antenna.  I  pur- 
chased one  of  your  standard  two-element  units  in 
February  of  this  year.  Prior  to  this  time  I  had  been 
using  a  collinear  array  about  one  wavelength  above 
ground.  The  transmitter  feeding  this  antenna  had  a 
power  output  of  about  35  watts,  and  results  were  quite 
discouraging. 

When  my  Gotham  arrived,  it  was  easily  assembled 
in  a  couple  hours.  The  same  transmitter  was  used  to 
excite  the  Gotham  antenna,  using  the  same  power  as 
before.  Results  have  been  quite  gratifying,  and  it  is 
interesting  to  note  that  in  the  three  months  since  using 
the  Gotham  antenna,  I  have  worked  87  foreign  coun- 
tries, all  continents,  and  30  zones.  ^ 


EVERY    FULL-SIZE    GOTHAM    ROTARY    BEAM   IS  ENGIN 

Your  Gotham  comes  to  you  completely  fabricated,  made 
(except  for  the  polystyrene  insulator)  entirely  of  new,  rust- 
less, first-quality  mill  stock  aluminum.  You'll  find  no  link 
coupling,  no  complicated  mounts,  no  tuning  stubs.  You  get 
good,  solid  aluminum  tubing  — and  more  of  it,  in  both  length 
and  thickness  (the  only  true  gauge  of  $  value)! 
No  flimsy  wire,  no  wood  to  rot  or  weather-proof.  W

I  am  able  to  keep  schedule  with  amateur  radio * 

in  the  Cape  Verde  Islands  every  week.  It  was  impos- 
sible to  even  hear  this  station  before  using  the  Gotham 
beam. 

Extremely  high  winds  are  prevalent  in  this  part 
of  Florida.  The  Gotham  beam  has  withstood  blows 
in  excess  of  .50  miles  an  hour  without  failure. 

The  elements  bend  almost  double  in  these  high 
winds,  but  readily  return  to  their  original  configura- 
tion when  the  wind  abates.  I  feel  that  this  is  an 
extremely  important  feature  of  the  Gotham  antenna. 

I  have  enthusiastically  recommended  Gotham 
to  all  the  hams  who  ask  what  type  I  am  using  (and 
most  of  them  do,  when  I  tell  them  the  amount  of 
power  I'm  using).  I  wish  you  every  success  with  your 
product,  and  feel  that  it  is  well  worth  the  modest  price. 

Yours  very  truly, 
(Names  and  *call  letters  upon  request.) 


EERED  FOR   SIMPLICITY,  STRENGTH,    PERFORMANCE 

Easy  assembly,  simple  and  quick  mashing  of  line  to  antenna. 
Yet  Gotham's  price  is  25^o  'o  ^^lo  'o^er  than  the  "toy" 
midget  beams  which  Gotham  so  easily  out-performs.

What  Is  This  Thing 

Called  the  ''Hump'* 

in  CODE? 


J.  HE  hump  (around  8  words)  is  the 
thing  that  tells  you  you  have  wasted 
your  time  by  starting  out  wrong. 
Thirty  years  ago  when  we  started  teach- 
ing Code  our  students  too  ran  head-on 
into  the  hump.  We  went  to  work  to  find  out  why.  TWO-PHASE, 
STEP  BY  STEP  instruction  is  the  perfect  answer.  In  this  method 
dotdash  is  not  A.  The  SOUND  resulting  from  dotdash  is  A.  There 
is  also  the  important  factor  of  correct  timing.  If  the  signals  are  not 
timed  correctly  the  resulting  sound  will  not  be  correct.  There  are 
many,  many  things  connected  with  proper  Code  instruction,  many 
of  them  so  small  they  seem  inconsequential.  Others  are  so  technical 
that  many  so-called  experts  fail  to  understand  them.  It's  a  long 
story  but  I  have  it  all  written  up  and  will  be  glad  to  send  it  to  you. 
A  postcard  will  bring  you  the  full  story.

CQ-1)  amplifier.  Although  the  receiver  was 
usually  limited  to  'phone  reception  only,  the 
"rushing"  noise  of  very  strong  c.w.  signals  could 
sometimes  be  copied.  A  separate  random-length 
antenna  was  used  for  receiving. 


Fig.  3  —  Transistor  receiver  using  a  crystal  detector 
and  transistor  amplifier. 

Results 

A  total  of  four  two-way  contacts,  two  'phone 
and  two  c.w.,  was  made  with  Field  Day  stations 
WlICP/1  and  WlDXI/1.  Both  of  these  stations 
reported  the  solar-powered  signals  loud  and 
clear.  Although  the  distances  involved  for  these 
contacts  were  only  a  few  hundred  feet,  several 
miles  could  probably  be  worked  with  proper  an- 
tennas and  good  conditions. 


Code-Practice  Oscillator 

(Continued  from  page  22) 

the  peak  current,  and  in  conjunction  with  the 
20-Mf.  condenser  provides  sufficient  filtering  to 
give  a  crystal-like  tone.  The  two  resistors  in  series 
across  the  plate  supply  serve  as  a  bleeder  and  help 
to  hold  the  voltage  under  control  when  the  oscil- 
lator section  is  not  operating. 

The  second  triode  section  of  the  12AU7  func- 
tions as  an  oscillator  in  a  Hartley  circuit  in  which 
the  plate  is  at  ground  potential  for  audio,  with 
output  taken  from  the  cathode  circuit.  The  volt- 
age drop  across  the  2000-ohm  resistor  in  the  plate- 
supply  section  provides  the  necessary  10  volts  to 
bias  the  triode  to  cut-off.  Only  the  bias  voltage  of 
10  volts  appears  across  the  key. 

The  3-4-ohm  voice  coil  of  the  usual  2-  to  4-inch 
speaker  is  connected  directly  in  the  cathode  re- 
turn, eliminating  the  output  to  voice-coil  trans- 
former usually  required.  A  speaker  without  the 
output  transformer  compares  in  cost  with  low- 
cost  'phones,  therefore  speaker  output  can  be 
obtained  without  increased  cost.  If  it  is  desired 
to  use  headphones,  thej'  may  be  connected  at  the 
points  indicated.  Suitable  output  was  obtained 
using  'phones  from  500  ohms  up.  (If  the  speaker 
is  omitted,  the  negative  supply  lead  is  connected 
directly  to  the  bottom  of  Li.) 

The  heater  circuit  should  not  be  grounded,  be- 
cause the  full  plate  voltage  would  appear  between 
the  cathode  and  heater  in  the  rectifier  section. 
With  the  heater  floating,  the  cathode-to-heater 
insulation  of  the  two  sections  is  in  series,  provid- 
ing sufficient  rating  for  the  voltage  used.

Con  s  tru  c  Hon 

To  benefit  from  the  circuit  design,  the  unit 
should  be  completely  enclosed  in  a  cabinet.  A 
midget  speaker  case  makes  a  fine  enclosure,  and 
can  be  fitted  with  a  subpanel  and,  if  required,  a 
perforated  metal  back  plate.  Alternately,  a  slop- 
ing-front meter  case  can  be  easily  fitted  with  a 
grille  at  even  less  cost. 

The  original  unit  pictured  was  constructed  in 
a  case  which  may  be  recognized  as  a  surplus  elec- 
tric-blanket control.  A  perforated  metal  speaker 
grille  replaces  the  original  thermometer-type  dial 
arrangement.  The  knob  on  the  left  is  the  off-on 
switch  which  was  an  original  part.  The  key  jack 
is  located  behind  the  hole  on  the  right.  Although 
these  surplus  units  have  been  available  for  a 
nominal  price,  few  parts,  other  than  the  case,  are 
adaptable  to  this  construction.

Wiring  is  straightforward  and  no  difficulty  will 
be  experienced  if  the  socket  terminals  are  checked 
carefully  and  the  proper  polarity  of  the  20-/zf. 
electrob'tic  filter  condenser  is  observed.  Polarity 
of  the  coil  Li  is  not  critical,  in  event  one  of  an- 
other make  is  used  and  its  leads  are  coded  differ- 
ently from  the  one  shown  (the  center-tap  must 
of  course  be  correctly  identified).  Since  the  values 
of  Li  and  C'2  determine  the  tone,  any  large  devia- 
tion in  Li  may  require  a  change  in  the  value  of  C2. 
A  simple  trial-and-error  process  will  achieve  a 
pleasing  tone.

amplifier  grid  current.  This  should  be  3  or  4  ma. 
with  a  doubler  plate  current  of  about  20  ma. 
Attach  a  10- watt  light  bulb  as  a  dummy  load  and 
tune  the  final  amplifier  for  maximum  brightness 
of  the  bull).  The  bulb  should  just  perceptibly 
brighten  further  with  voice  modulation.  The 
plate-current  dip  in  the  final  amplifier  should  run 
around  40  to  50  ma.,  loaded,  and  the  modulator 
plate  current  should  kick  up  from  a  static  value 
of  2.5  ma.  to  a  maximum  of  50  to  60  ma. 

Measure  the  bias  voltage  across  the  resistor 
in  the  center  tap  of  the  power  supply  and  adjust 
the  slider  for  22  volts  bias.  The  slider  should  be 
set  at  166  ohms.  Make  the  adjustment  with  the 
transmitter  on,  as  it  takes  the  full  current  in  the 
transmit  position  to  cause  the  22-volt  drop  across 
the  resistor.  The  voltage  will  be  less  during  re-

MOST  DEPENDABLE 

If  disaster  should  strike,  will  your  com- 
munication equipment  meet  the  test?  In 
time  of  disaster,  there  is  no  substitute 
for  dependability  —  even  initial  cost 
becomes  secondary!  Long  life,  rugged- 
ness  and  reliability  were  the  watch- 
words in  the  final  selection  of  these 
tubes.  If  you  are  planning  new  fixed  or 
mobile  stations,  insist  on  AMPEREX  type 
5894  or  6252  to  be  sure!

The  AMPEREX  6252  ICAS  higher  voltage  and  input  ratings  show  the 
advantage  of  the  independently  suspended  anode  construction 
which  eliminates  the  need  for  internal  insulation.  Competitive  tubes 
use  mica  insulators  between  the  plate  and  the  rest  of  the  internal

ceiving,  but  the  bias  is  not  used  during  reception. 
For  dependable  service,  which  is  necessary 
in  c.d.  work,  all  components  should  be  used  well 
within  their  ratings.  This  applies  to  tubes  as  well 
as  resistors  and  condensers.  A  stock  of  spare  tubes 
and  parts  should  be  kept  wdth  the  equipment  in 
case  of  failure  at  a  critical  time. 

Results 

In  actual  use  on  the  air  in  c.d.  drills,  this  little 
peanut  whistle  has  performed  very  well.  The  re- 
ceiver also  performs  well,  and  although  it  is  not 
selective  enough  for  regular  amateur  use  (it  could 
be  made  so)  it  is  ideal  for  c.d.  w^ork.  No  retuning 
is  necessary  for  different  net  stations  even  though 
their  crystals  are  1  or  2  kilocycles  high  or  low. 

Installed  as  a  mobile,  other  mobiles  have  been 
worked  at  distances  up  to  30  miles  during  c.d. 
drills. 

Last  but  not  least,  there  is  no  TVI  from 
harmonics  when  a  good  low-pass  filter  is  used 
(this  is  a  must),  even  though  the  TV  set  is  in 
the  same  room.  However,  it  may  be  necessary 
to  install  a  few  high-pass  filters  on  some  near-by 
TV  sets  to  prevent  fundamental  overload,  even 
with  the  low  power.

contact;  (2)  your  call;  (3)   RST  report  given;  (4)  ARRL 
section.  Example:  NR  1  W0ZZZ  579  Kansas. 

4)  One  point  may  be  counted  for  each  exchange  sent  and 
acknowledged.  One  point  may  be  counted  for  each  ex- 
change received.  For  contest  credit  a  station  may  be 
worked  once  on  'phone  and  once  on  c.w.  on  each  band. 
VE/VO  stations  will  multiply  the  total  points  by  the 
number  of  U.S.A.  ARRL  sections  worked.  W/K  stations 
vdW  multiply  the  total  points  by  the  number  of  VE  areas 
worked  and  also  by  7.11,  there  being  nine  Canadian  areas 
(VEl  through  8  plus  VO). 

A  station  using  a  power  input  of  30  watts  or  less  will 
receive  an  additional  multiplier  of  2,  and  a  station  using 
from  30  watts  to  100  watts  will  receive  one  of  1.5.  The 
final  score  consists  of  "total  points"  multipUed  by  "sec- 
tions" (times  7.11  in  case  of  W/K  stations)  multiplied  by 
the  "power  multiplier." 

5)  Each  entry  must  be  accompanied  by  the  following 
declaration:  "I  hereby  state  that  my  station  was  operated 
strictly  in  accordance  with  the  rules  of  the  contest  and 
governmental  radio  regulations,  and  I  agree  that  the 
decision  of  the  Contest  Committee  of  the  Montreal  Ama- 
teur Radio  Club,  Inc.,  shall  be  final  in  all  cases  of  dispute." 

6)  All  entries  shall  be  sent  to  Gordy  Webster,  VE2BB, 
69  Pine  Beach,  Dorval,  Quebec,  Canada,  and  must  be  post- 
marked not  later  than  midnight  October  15,  1955. 


During  a  practice  alert,  messages  poured  into 
Pinedale,  Calif.,  civil  defense  headquarters.  The 
texts  of  these  messages  were  concerned  with 
evacuation,  radioactive  fall-out,  etc.  Operators 
were  stunned  though  when  they  received  this  one : 
"Waiting  since  5:30,  stop.  Dinner  cold,  stop. 
Drop  dead,  end."  It  was  sent  by  the  wife  of  a 
Fresno  ham!

OR  more  than  forty  years,  the  Ameri- 
can Radio  Relay  League  has  been  the 
amateur's  own  organization,  operating 
under  pohcies  established  by  directors  of 
his  choice,  serving  as  a  clearing-house  for 
information,  representing  him  at  inter- 
national conventions,  before  Federal 
agencies  and  national  groups,  and  pro- 
viding other  services  to  make  his  hobby 
enjoyable  as  well  as  useful.

'embers  of  the  League  in  eight  ARRL 
Divisions  will  soon  be  nominating  and 
voting  for  the  directors  who  will  represent 
them  for  the  next  two  years.  Every  amateur 
taking  part  in  these  elections  helps  further 
the  aims  and  protects  the  privileges  he  has 
as  a  ham.  Naturally,  only  League  mem-

switch  to  the  "in"  position  and  adjust  the  slugs 
for  maximum  reading  on  the  S-meter.  If  the  re- 
ceiver does  not  have  an  S-meter,  the  preamplifier 
can  be  adjusted  for  maximum  signal  or  noise 
while  listening  to  the  audio  output  of  the  receiver 
with  a  pair  of  headphones  (this  eliminates  outside 
noises).  If  the  receiver  has  an  S-meter,  it  should 
show  an  increase  of  4  to  6  S-units  when  switching 
the  preamplifier  in.  Coils  have  not  been  included 
for  80  and  40  meters,  since  most  receivers  operate 
satisfactorily  at  the  lower  frequencies  and  a  pre-

meter  stage  is  too  small.  Ce  should  then  be  set 
at  less  capacitance  than  originally,  the  VFO 
reset  to  4000  kc,  and  the  slug  in  to  readjusted 
for  maximum  grid  current.  If  the  readjustment 
for  maximum  grid  current  at  3200  kc.  has  re- 
quired a  decrease  in  the  capacitance  of  C'e,  the 
tuning  range  of  the  80-meter  stage  is  too  great. 
In  this  case,  Ce  should  be  set  initially  at  a  higher 
capacitance  at  4000  kc. 

When  an  adjustment  has  been  secured  where 
the  grid  current  remains  essentially  constant 
across  the  80-meter  band,  the  bandsvvitch  should 
be  turned  to  the  40-meter  position.  The  VFO 
should  be  set  to  the  low-frequency  end  of  the 
band,  and  a  high-resistance  voltmeter  connected 


The  v.h.f.  filter  components  are  enclosed  in  an  ex- 
tension added  at  the  rear  of  the  exciter  chassis.  The 
switch  section  is  S2e- 


across  the  40-meter  doubler  grid  leak.  Cy  should 
then  be  adjusted  for  maximum  voltage.  This 
voltage  should  remain  essentially  constant  over 
the  band. 

The  4t>meter  stage,  as  well  as  the  following 
multiplier  stages,  are  lined  up  by  the  same 
method  used  for  the  80-meter  stage.  The  band- 
set  condenser  is  set  at  midrange  in  each  case, 
the  VFO  is  tuned  to  the  high-frequency  end 
of  the  band,  the  slug  in  the  plate  inductor  is 
adjusted  for  maximum  807  grid  current,  and  then 
a  check  made  at  the  low-frequency  end  of  the 
band,  repeating  the  process  if  there  is  a  con- 
spicuous difference  in  grid  current  at  the  ends 
of  the  bands.  On  21  Mc.  it  should  be  necessary 
to  adjust  only  the  slug  of  L5  after  the  circuit  has 
been  lined  up  on  14  Mc. 

If  parasitic  oscillation  occurs  in  the  final 
amplifier  when  plate  and  screen  voltages  are 
applied,  L7,  Lg,  and  L9  should  be  adjusted,  a 
turn  at  a  time,  until  the  parasitic  is  suppressed. 
In  the  multiband  tuner,  it  is  advisal)le  to  adjust 
Lii  carefully  so  that  14  Mc.  comes  at  maximum 
capacitance  of  Tis,  and  adjust  Lw  so  that  7.3 
Mc.  comes  with  the  capacitor  near  minimum 
capacitance.  This  procedure  should  result  in 
maximum  separation  between  funtlamental  and 
harmonic  resonances. 

After  the  stei)S  descril)ed  earlier  were  taken, 
no  sign  of  instability  could  l)e  found  on   any

uled  for  the  contest  week  end,  September  17th  and  18th. 
K4AMX  will  be  operating  from  Mt.  Mitchell,  N.  C.  (highest 
point  in  eastern  U.S.A.),  on  50,  144  and  possibly  220  Mc. 
Frequency  on  2  will  be  144.23,  with  16-element  horizontal 
array. 

An  International  2-Meter  Relay  is  planned  for  the  con- 
test week  end  by  the  2-Meter  and  Down  Club  of  Los 
Angeles.  Stations  will  be  manned  at  various  Cahfornia  high 
spots  from  the  Mexican  border  north,  but  cooperation  of 
W7s  will  be  needed  to  complete  the  route  to  Canada.  The 
northern  terminal  will  probably  be  VE7FJ,  in  the  Van- 
couver area. 

The  third-party  traffic  angle  has  been  taken  into  consid- 
eration (we  have  an  agreement  with  Canada,  but  not  with 
Mexico)  and  if  no  special  dispensation  can  be  arranged  for 
the  occasion,  the  work  from  the  Mexican  end  will  be  handled 
in  such  a  way  as  to  conform  completely  with  our  inter- 
national obligations  in  such  matters. 

OES  gang:  Due  to  long  copy  this  month  we're 
holding  back  OES  notes.  Will  combine  two 
months  in  ne.xt  issue.  Reports  are  getting  better 
all  the  time.  Keep  'em  coming!

limits  of  800-900  cycles.  No  major  difficulty 
having  been  disclosed  by  a  preliminary  examina- 
tion, the  petition  has  now  been  filed  as  follows: 

FEDERAL  COMMUNICATIONS  COMMISSION 
Petition  for  amendment  of  Paragraphs   12.   107(c)    ) 
and    (d)    of   the   Rules   Governing  Amateur  Radio  y 
Service,   titled   "Special  Provisions  Regarding  Ra-  C 
dio  Teleprinter  Transmissions."  ) 

Petition  of  the  American  Radio  Relay  League,  Inc. 

The  American  Radio  Relay  League  files  this  petition  on 
behalf  of  the  more  than  47,000  U.  S. -licensed  amateur 
radio  operators  who  are  members  of  the  League. 

This  petition  was  formulated  pursuant  to  instructions 
of  the  Board  of  Directors  of  the  League. 

The  League  proposes  that  the  present  restriction  on  fre- 
quency-sliift  keying  in  the  amateur  service,  now  800  to  900 
cycles  shift,  be  removed  and  that  instead  there  be  permitted 
any  shift  under  900  cycles.  Specifically,  the  League  proposes 
that  Section  12.  107(c)  of  the  amateur  rules  be  amended 
to  read  as  follows: 

(c)  When  frequency-shift  keying  (type  F-1  emission) 
is  utilized,  the  deviation  in  frequency  from  the  mark 
signal  to  the  space  signal,  or  from  the  space  signal  to  the 
mark  signal,  shall  be  less  than  900  cycles  per  second. 

and  in  consonance  therewith,  that  Section  12.  107(d)  be 
amended  to  read  as  follows: 

(d)  When  audio-frequency-shift  keying  (type  A-2  or 
type  F-2  emission)  is  utilized,  the  highest  fundamental 
modulation  audio  frequency  shall  not  exceed  .3000  cycles 
per  second,  and  the  difference  between  the  modulating 
audio  frequency  for  the  mark  signal  and  that  for  the 
space  signal  shall  be  less  than  900  cycles  per  second. 

This  proposal  is  based  on  the  following  considerations: 

Fxperimentation 
In  recent  years,  with  the  availability  of  teleprinters  to 
the  Amateur  Service,  a  number  of  experimentally-inclined 
amateurs  have  been  using  radioteleprinter  communication, 
first  with  audio-frequency-shift  keying  primarily  on  the 
144-Mc.  band  and,  since  the  Commission's  authorization 
for  the  use  of  F-1  emission  on  lower-freriuency  bands,  with 
carrier  frequency-shift-k eying  in  the  non-voice  portions  of 
the  .3. .5-,  7-,  and  14-Mc.  bands.  Although  at  one  time  the 
number  of  available  printer  units  sharply  limited  the 
number  of  amateurs  who  could  engage  in  this  work,  at 
present  there  is  an  adequate  supply  of  such  imits  with  the 
result  that  amateur  use  of  F-1  teleprinter  communication 
is  increasing  rapidly.  The  League  believes  that  this  is 
anotlier  field  in  which  the  amateurs  can  contribute  to  the 
advancement  of  the  art,  but  amateurs  are  now  handicapped 
with  the  limitation  of  frecjuency  shift  within  the  range 
800-900  cycles  per  second.  A  number  of  leading  amateurs 
in  this  field  have  indicated  a  strong  interest  in  conducting 
experimental  communication  with  lesser  frequency  shift, 
and  the  League  believes  they  should  be  encouraged  to  do 
so.  It  is  understood  that  commercial  and  military  research 
groups  also  feel  that  a  shift  of  considerably  less  than  the 
present  850-cycle  standard  may  well  be  found  to  be  much 
more  effective  in  teleprinter  communication.  Tlie  League 
urges  tlie  Commission  to  permit  amateurs  to  take  part  in 
this  investigation. 

Improremenl  in  Techniques 

A  reduction  in  [jermissible  frei|uency  shift  will  allow  the 
use  of  receivers  with  narrower  bandwidth,  resulting  in  an 
improvement  in  signal-to-noise  ratio.  It  will  be  possible  to 
shariien  intermediate-frequency  filters  and  amplifiers.  It 
is  also  expected  that  a  reduction  in  frequency  shift  will 
lessen  the  effects  of  selective  fading,  since  this  problem  is 
eased  when  mark  and  space  signals  are  brought  closer  to- 
gether. A  smaller  freciuency  shift  is  also  more  easily  obtain- 
able when  using  crystal  control,  compared  to  the  present 
difficulty  of  achieving  direct  850-cycle  shifts  with  3.5-Mc. 
crystals. 

Reduction  in  Interference 

Although  this  is  a  matter  of  lesser  importance,  it  should  be 
mentioned  (if  only  to  point  out  that  potential  interference

to  other  types  of  emission  in  these  amateur  bands  \vill 
certainly  not  be  increased)  that  it  is  expected  the  use  of  a 
lesser  frequency  shift  will  accomplish  a  reduction  in  inter- 
ference. Since,  practically  speaking,  an  F-1  signal  uses  the 
spectrum  space  of  a  c.w.  signal  with  corresponding  onoff 
keying,  plus  the  frequency  shift,  it  is  apparent  that  a  smaller 
shift  will  occupy  less  sjiectrum  space  and  thereby  provide 
less  opijortunity  for  interference. 
*     *     * 

In  summary,  the  League  believes  that  authorization  for 
amateurs  to  employ  F-1  emission  frequency  shifts  less  than 
900  cycles  per  second  will  permit  more  extensive  experi- 
mentation with  radioteleprinter  communication,  will  result 
in  an  improvement  in  and  simplification  of  teleprinter 
techniques,  and  thereby  will  provide  a  more  reliable  means 
of  communication.

Board  meeting  minutes  in  July  QST  (paragraph 
59).  Mr.  Cowan  of  the  West  Gulf  Division,  not 
Mr.  Gowan  of  the  Dakota  Division,  is  the  third

official  who  could  not  be  contacted  by  telephone. 
W3AVL  and  W3ZZK  relayed  traffic  via  2  meters 
to  WN3ZYB  in  Calvert  County.  Eighteen  c.d. 
messages  were  handled  during  the  alert.  Partici- 
pating amateurs  received  congratulations  from 
the  county  Civil  Defense  Director  for  the  man- 
ner in  which  these  messages  were  handled. 

Massachusetts 

In  Winthrop,  EC  and  RO  WlBB  alerted  his 
group  to  participate  on  the  basis  that  radio  was 
the  only  means  of  communication.  Both  control 
and  alternate  control  stations  were  operated,  on 
six  meters.  The  test  was  conducted  on  an  area 
basis,  although  local  stations  were  ready  and 
standing  l)v. 

Acting  EC  and  Radio  Officer  WlWGN  re- 
ported some  confusion  in  New  Bedford  as  to 
whether  the  city  was  to  be  bombed  or  not.  Nev- 
ertheless, amateurs  participated  wholeheartedly. 
The  control  station  was  operated  from  1200  to 
2145  by  five  amateurs  to  maintain  contact  with 
sector  headquarters,  with  mobiles  in  New  Bed- 
ford and  the  center  of  the  city.  Ten  and  two 
meters  were  used. 

Sector  1-B,  which  includes  21  cities  and  to\ATis 
in  Eastern  Mass.,  was  activated  from  Quincy 
City  Hall  by  nine  amateurs.  Seventeen  towns  re- 
ported into  the  nets  on  ten  and  two  meters.  Net 
control  WlIA  was  on  the  air  from  1130  the  15th 
until  1330  the  following  day.

EC  and  RO  WlSPF  of  Worcester  reports  par- 
ticipation l)y  five  amateurs  and  two  non-amateur 
operators.  The  city  was  "bombed"  at  1428,  smash- 
ing all  communications  in  Worcester,  leaving  only 
one  control  center  and  two  mobiles  in  operation. 
Those  left  had  a  mighty  hard  time  of  it,  demon- 
strating that  additional  and  more  dispersed  facil- 
ities are  needed. 

Sector  1-C  was  alerted  at  1800  and  was  on  the 
air  until  2)^00.  Traffic  was  handled  regarding  food 
shortages  for  the  evacuees  who  had  been  moved 
from  Boston  to  Framingham.  Communications 
from  Framingham  to  sector  headquarters  in 
Sherborn  was  on  50,745  kc.  The  Sector  1-C  RO 
is  WIZOP.  the  EC  WIAIEG.  The  laHer  is  also  al- 
ternate radio  officer  and  sent  us  this  information. 

Waltham  EC  WIJSM  reports  that  they  were 
alerted  for  control  center  and  zone  base  action 
from  1800  to  2300  on  the  15th.  Four  amateurs 
were  active.  The  local  net  tied  in  zone  bases  to 
the  control  center.

New  Jersey 

Maplewood  EC  W2C0T  reports  sixteen  sta- 
tions on  stand-by,  of  which  five  were  mobile,  but 
no  local  incidents  were  attempted. 

New  York 

K2DVC,  EC  and  RO  of  Genessee  County, 
N.  Y.,  combined  his  RACES  and  AREC  oper- 
ators for  a  successful  RACES  test  on  RACES 
frequencies.  K2IDQ  set  up  his  rig  at  c.d.  head- 
quarters. Activity  commenced  shortly  before 
noon  on  the  15th  and  continued  until  1022  the 
16th.  Ten  and  six  meters  were  used.  Everything 
went  off  fine,  says  K2DVC,  and  the  c.d.  director 
was  very  pleased  and  impressed. 

Ontario 

VE3AIB  took  over  in  Operation  Alert  due  to 
the  absence  of  the  regular  communications  offi- 
cer (and  Toronto  EC)  VE3IL.  Operation  was 
conducted  on  80,  75,  40,  and  2  meters,  concerned 
primarily  wath  traffic  direct  between  the  various 
regional  headquarters  and  provincial  headquar- 
ters at  Toronto.  Most  regions  also  operated  their 
own  amateur  nets  on  other  frequencies.  This  set- 
up worked  very  well  during  the  hours  1800  to 
2300  EST  on  the  15th. 

Pennsylvania 

Philadelphia  County's  Operation  Alert  was 
primarily  concerned  with  evacuation  procedures. 
Four  sample  evacuations  were  conducted,  one 
from  each  of  the  city's  four  c.d.  regions.  Com- 
munications with  the  caravans  were  maintained 
at  all  times  to  the  respective  regional  control 
centers  on  29  Mc.  A  Navy  blimp  carried  civil  de- 
fense observations,  communications  with  Phil- 
adelphia's Mobile  Communications  unit  being 
conducted  on  RACES  frequencies  under  the 
call  K2NBD.  The  mobile  unit  operated  as 
W3YXU/3.  This  mobile  unit  also  maintained 
contact  with  the  four  control  centers  on  29  Mc. 
The  turnout  was  large  and  verj^  encouraging.  EC 
W3DYL  lists  41  amateurs  and  10  amateur/ 
RACES  mobiles  participating. 

Puerto  Rico 

Puerto  Rican  amateurs  participated  in  Opera- 
tion Alert  through  their  club  station  KP4ID, 
located  at  c.d.  headquarters  in  Rio  Piedras.  This 
station  was  on  the  air  from  0800  through  2030 
on  June  15th.  Operation  was  on  3925  kc.  Sixteen 
stations  on  Puerto  Rico  and  the  Virgin  Islands 
checked  in,  handling  53  messages.  Stations  were 
also  located  at  Gurabo  C.D.  Headquarters  and 
Ramey  Air  Force  Base,  the  latter  maintaining 
contact  with  FCDA  Regional  headquarters  in 
Thomasville,  Georgia.  A  total  of  22  amateurs 
participated. 

Tennessee 

Five  amateur  stations  were  set  up  and  operat- 
ing in  Chattanooga  when  the  yellow  alert  was 
sounded  on  June  15th,  according  to  newspaper

the  RACES  group,  maintaining  communications 
with  other  cities  in  the  state.  More  than  50  op- 
erators participated,  and  amateurs  supplied  their 
own  oriuipment. 

I'^ight  emergenc3'-po\vered  rigs  were  used  by  the 
Oak  Ridge  gang  over  a  24-hour  period.  SEC 
W4RRV  was  present  at  c.d.  headquarters,  along 
with  the  city  manager  and  c.d.  director.  All 
transmitters  were  of  home  construction. 


Virginia 

The  Hampton  RACES  organization,  under  EC 
W4AJA  and  RO  W4RGN.  provided  the  nucleus 
for  ()j)eration  Alert  in  the  Hampton-Newport 
News-Warwick  area.  Nine  amateurs  staffed  the 
control  station  in  Hampton,  while  W4AJA  acted 
as  alternate  control.  Local  units  were  not  alerted, 
the  tricities  set-up  acting  in  support  of  Norfolk, 
the  target  area.  Sixty-five  official  messages  were 
handled. 

No  previous  planning  was  made  in  Norfolk, 
but  32  amateurs  responded  to  the  alert,  20  of 
whom  were  mol)ile.  Assignments  were  made  on 
the  air  or  in  person  after  the  alert.  At  1515  all 
mobile  and  portable  stations  were  called  in  for 
regrouping  and  reassignment.  Most  traffic  from 
then  on  was  directed  to  Richmond  (state  control). 
A  total  of  99  messages  were  handled.  The  boys 
had  their  transmitter  and  antenna  troubles,  but 
the  drill  went  off  successfullv. 

The  Falls  Church  RACES  net  held  their  own 
exercise  on  29,580  kc.  RO  W40P  operated  the 
control  station,  and  mobiles  were  stationed  at 
check  points  on  evacuation  routes.  Four  mobiles 
and  four  fixed  stations  participated,  handling 
nine  messages  without  difficulty.  C.D.  head- 
quarters RACES  station  in  Fairfax  was  covered 
by  mobile  W4TNQ,  with  VV4ZNU  assisting, 
maintaining  communication  with  Falls  Church 
on  145.3  Mc. 


Con  clu  sion  s 

The  first,  and  most  obvious,  conclusion  is  that 
a  great  deal  more  activity  was  conducted  than 
has  been  reported  above.  We  can  report  only  the 
information  we  receive.  Secondly,  we  congratu- 
late and  commend  all  who  participated,  whether 
an  authorized  or  pending  RACES  group,  on  their 
representation  of  amateur  radio  in  this  very 
important  national  activity  very  much  in  the 
public  eye.  Thirdly,  and  last  but  not  least,  we 
want  to  jjoint  out  to  those  who  operated  outside 
RACES  frequencies  (although  they  undoubtedly 
already  know  it)  that  they  are  conducting  tests 
that  are  almost  totally  unrealistic  in  view  of  the 
certainty  that  only  RACES  frequencies  under 
RACES  will  be  available  after  any  commence- 
ment of  hostilities.  It  doesn't  matter,  unfortu- 
nately, that  these  frequencies  are  not  sufficient 
for  our  n(!eds.  Until  or  unless  additional  fre- 
quencies can  be  made  available,  we  have  to  plan 
to  use  the  ones  we  have. 

Thanks  to  those  who  reported  for  making  it 
possible  for  us  to  give  some  idea  of  participation 
by  amateuis in  civil  defense  throughout  the  nation.

Radioteletype  Filter  Set 

One  of  the  stumbling  blocks  to  RTTY  opera- 
tion has  been  the  receiver-converter  filters  used  to 
separate  the  "mark"  and  "space"  signals,  and 
amateur  "scrounging"  of  one  type  or  another  has 
usually  been  the  only  recourse.  This  situation  has 
been  improved  by  the  recent  availability  of  the 
BF-Ml  and  BF-Sl  Radioteletype  Filters.  These 
compact  {4%  by  2^  by  2>2  inches  high)  units

U.  S.  N.  R. 


RE.\R  Au.MiRAi.  Henry  C.  Bruton  assumed 
duties  as  Director,  Xaval  Communications, 
on  1  April  1955,  succeeding  Rear  Admiral  Wil- 
liam B.  Amon  who  was  assigned  command  of 
B.\TDIV  TWO. 

In  his  new  assignment,  Admiral  Bruton  is  re- 
turning to  the  field  of  communications  in  which 
he  sei'ved  during  the  early  part  of  his  naval  career 
following  his  graduation  from  the  U.  S.  Naval 
Academy  in  1926.  He  is  holder  of  an  amateur 


radio  license  (since  1920),  a  degree  in  radio  en- 
gineering from  the  University  of  California,  and 
a  law  degree  from  George  Washington  University. 

A  large  part  of  his  career  has  been  in  the  sub- 
marine service.  During  Woild  War  II,  as  com- 
manding officer  of  the  USS  Greenling,  he  com- 
pleted four  successful  submarine  patrols,  credited 
with  a  total  of  11  sinkings.  He  also  participated 
in  the  Korean  hostilities  as  commanding  officer 
of  the  USS  Wisco)isin. 

Admiral  Bruton's  assignments  have  included 
Administrative  Aide  to  Fleet  Admiral  Chester 
Ximitz  when  he  was  Chief  of  Xaval  Operations, 
and  Aide  to  Fleet  Admiral  ICrnest  J.  King  when 
he  was  Commander-in-Chief,  U.  S.  Fleet.  From 
June,  1953,  to  Sej^tember,  1954,  he  was  Com- 
mander of  the  Xav>'  task  group  at  the  Bikini 
atom  bomb  tests,  and  then  was  named  Deputy 
Chief  of  Xaval  Operations  (Administration). 

Admiral  Bruton  holds  several  military  awards, 
including  the  Xavy  Cross.  He  is  a  member  of 
the  ARRL.  His  present  call  is  W4IH  and  although 
he  is  now  inactive  on  the  ham  bands,  he  peri- 
odically threatens  to  open  up  again  any  day.

r 


Take  the  Collins  75A4,  for  example.  Known  by  radio  amateurs  for 
its  high  signal  sensitivity  and  operating  stability,  this  versatile  re- 
ceiver uses  RCA  Receiving  Tubes  to  assure  maximum  circuit  perform- 
ance from  the  input  to  the  output. 

Here  are  reasons  why  leading  amateur  and  commercial  designers 
specify  RCA  Receiving  Tubes:  RCA  Tubes  are  known  for  their  back- 
ground "quietness"— a  feature  that  provides  a  lower  noise  threshold 
and  enables  you  to  boost  receiver  sensitivity.  RCA  Receiving  Tubes 
have  high  uniformity  of  characteristics,  can  be  "interchanged"  with- 
out a  lot  of  circuit  "fussing"— no  matter  where  or  when  you  buy  your 
tubes.  And  RCA  Receiving  Tubes  "stand  the  gaff"  of  on-air  opera- 
tions; you  can  plug  them  in  and  then  forget  them! 

There  is  an  RCA  Receiving  Tube  for  virtually  every  receiver  and 
transmitter  application  in  amateur  radio.  See  your  RCA  Tube  Dis- 
tributor for  the  types  you  need.  For  technical  data,  write  RCA,

It  Seems  to  Us... 


"IN  THE  PUBLIC  INTEREST  .  .  ." 

We  write  this  just  a  week  after  a  flood 
disaster  ravaged  our  Northeast,  still  aghast 
at  the  tragedy  of  loss  of  life  and  property, 
vet  with  a  growing  feeUng  of  pride  in  being 
"a  member  of  the  body  of  amateur  radio  which 
did  such  a  magnificent  job  of  providing  vital 
emergency  communication. 

This  brief  tribute  will  be  woefully  incom- 
plete. In  the  true  tradition  of  service,  amateurs 
have  been  too  busily  engaged  in  disaster  work 
to  take  time  out  to  inform  Hq.  of  their  many 
accomphshments.  Yet  our  own  experience, 
even  though  Umited  almost  entirely  to  the  two 
spot  frequencies  housing  the  Connecticut 
'phone  and  c.w.  nets,  makes  it  thoroughly 
evident  that  amateurs  throughout  the  disaster 
areas  banded  together  in  the  public  interest, 
convenience  and  necessity,  whether  they  wore 
c.d.  armbands  and  manned  the  Radio  Amateur 
Civil  Emergency  Service  organization,  or 
served  strictly  as  amateurs  in  the  various  sec- 
tion and  regional  nets.  A  full  week  after  the 
first  alert,  many  are  still  at  their  posts,  ex- 
hausted from  endless  hours  at  key  or  mike, 
hanging  on  because  of  the  importance  of  the 
job  being  done.  . 

In  general  amateur  communications  worked 
smoothly  despite  the  confusion  which  Nature 
foisted  on  us  all.  Net  disciphne  was  good, 
station  cooperation  excellent.  Amateurs  bv 
the  hundreds,  not  in  the  immediate  flooded 
areas,  must  have  been  standing  by  hour  after 
hour  to  offer  assistance  if  and  when  needed, 
and  we'd  hke  to  observe  that  one  good  measure 
of  the  efficiency  of  disaster  commumcation  is 
the  number  of  stations  standing  silently  by. 
The  key  was  teamwork,  the  aim  to  get  the 
job  done. 

Teamwork  and  efficiency  it  was.  in  one 
instance  WlAW  had  a  circuit  to  a  station  m  a 
hard-hit  area  for  most  of  four  days  without 
knowing  just  where  he  was  located,  what  kind 
of  power  he  was  using,  or  even  his  name,  and 
when  the  press  made  inquiries  for  such  in- 
formation we  were  not  ashamed  to  profess 
ignorance  —  there  just  wasn't  time  for  such 
details.  In  another  instance,  few  if  any  ama^ 
teurs  handUng  official  disaster  traffic  to  and 
from  one  civil-defense  installation  knew  of 
the  heroic  performance  of  its  operator  — his 


house  had  been  washed  away  and  his  mother 
drowned,  vet  as  an  amateur  his  first  thought 
was  to  fight  his  way  to  c.d.  headquarters  to 
provide  the  town  with  urgently-needed  com- 
munication. 

QST  wants  to  record  the  performance  of  the 
amateur  body  in  the  Great  Flood  of  1955,  and 
we  solicit  your  help  in  providing  information 
to  that  end,  whether  it  be  an  outstanding 
story  of  personal  or  group  sacrifice  and  accom- 
pUshment,  or  the  mere  fact  that  you  were 
standing  by  to  help  if  needed.  Then  there  is 
one  more  job  to  be  done.  We  must  all  admit 
there  were  occasional  foul-ups  in  our  opera- 
tions just  as  there  were  in  all  flood-fighting 
activities.  As  will  undoubtedly  be  done  by 
other  agencies  wanting  to  profit  by  the  tragedy 
of  experience,  we  should  examine  our  own 
performance  to  determine  how  next  time — 
and  there  will  be  a  next  time  —  we  can  be  even 
better  prepared. 

THE  REASON  WHY 

From  time  to  time  most  of  us  have  occasion 
to  explain  amateur  radio  to  BCLs.  It  isn't 
too  hard  to  tell  them  how  we  establish  contact 
with  another  ham,  nor  to  answer  the  perennial 
question  "How  far  can  you  talk  with  that 
thing?"  —  perhaps  with  a  sUght  exaggeration! 
More  difficult  to  explain  is  the  fascination 
which  keeps  us  active  year  after  year,  which 
makes  us  stay  up  all  night  calling  CQ  bb 
or  chasing  DX.         ,       .     .  ,  ,    , , 

One  of  the  best  descnptions  of  our  hobby 
was  written  not  by  an  amateur  but  by  a 
sociologist  who  had  picked  amateur  radio 
as  an  example  of  an  American  institution 
which  had  gone  from  its  earUest  beginnings  to 
a  respected  position  in  the  Twentieth  Century. 
In  his  doctorate  thesis  the  sociologist,  Di-. 
Raymond  V.  Bowers  of  Yale  University,  asked 
himself  "^Miat  are  the  elements  of  this  core 
complex  in  the  amateur  radio  institution?  , 
then  proceeded  to  answer  in  this  fashion: 

The  central  trait  is  the  means  of  communi- 
cation with  others  on  equal  terms,  of  finding 
friendship,  adventure  and  prestige  while 
seated  at  one's  own  fireside.  In  picking  his 
human  contacts  out  of  the  air  the  amateur 
is  not  seen  by  them.  ...  He  is  not  known 
by  the  company  he  keeps  nor  by  the  clothes 


he  wears  but  by  the  signals  he  emits.  He 
enters  a  new  world  whose  qualifications  for 
success  are  within  his  reach.  A  good  home- 
made set  give.s  liim  more  prestige  than  a 
commercially-manufactured  one.  There  are 
no  century-old  class  prejudices  to  impede  liis 
progress.  He  enters  a  thoroughlj'  democratic 
world  where  he  rises  or  falls  by  liis  own 
efforts.  When  he  is  W9XYZ,  a  beginner,  the 
radio  elders  help  him  willingly,  and  when  he 
becomes  W9XYZ  the  record-breaker  and 
efficient  traffic  handler,  he  willingly  helps  the 
>ounger  generation.  Without  a  pedigree,  a 
chauffeur,  or  an  old  master  decorating  hi.s 
living  room  he  can  become  a  prince  —  of  the 
air.  At  the  close  of  the  day,  filled  with  the 
monotonous  routine  of  the  machine  age,  he 
can  find  adventure,  \-icarious  travel,  prestige 
and  friendsliip  by  throwing  in  the  switch 
and  pounding  his  signals  into  the  air. 

Though  this  was  written  over  twenty  years 
ago,  it  still  expresses  the  attractions  that  call 
us  to  our  hobby  today.  Though  perhaps  the 
game  has  become  more  compUcated,  a  new 
and  friendlj^  world  still  opens  its  arms  in 
welcome  whenever  the  rig  is  fired  up  and  a 
good  fist  or  well-modulated  voice  sends  out 
a  CQ. 


ers  that  you  won't  want  to  mifis,  and  that  "  once-a-year " 
opportunity  to  viait  with  all  of  the  old  gang.  A  social  hour 
and  a  'teen  party  have  been  scheduled  as  well  as  YL  and 
XYL  activities.  The  most  important  part  hasn't  been  for- 
gotten either  —  the  food  will  be  good  and  there  will  be 
plenty  of  it.  For  reservation  information  write  P.  O.  Box

Typical  "Hoosier  Hospitality"  will  be  extended  to  al' 
amateurs  and  friends  attending  this  Convention.  The  Hotel 
Ohver  will  be  headquarters,  although  other  fine  hotels  in  the 
city  mil  share  in  the  accommodations  for  guests.  Rates  are 
moderate,  and  a  special  discount  of  25  per  cent  is  ofifered  to 
conventioneers. 

The  program  will  be  of  interest  to  amateurs  in  every  phase 
of  operating,  be  it  s.s.b.,  v.h.f.,  DX,  MARS,  or  what  have 
you.  Even  tiie  Novice  hasn't  been  forgotten.  There  will  be 
lectures  and  demonstrations  of  general  interest  and  again, 
these  features  will  be  headed  by  the  top  men  in  their  fields. 
There  will  be  a  banquet  on  Saturday  night,  with  a  nation- 
ally-known speaker  and  headhne  entertainment.  The  mobile 
enthusiast  will  find  plenty  of  acti\aty  to  attract  liis  attention, 
and  of  course  there  will  be  an  initiation  into  the  Royal  Order 
of  Wouff  Hong  at  midnight  on  Saturday. 

Has  the  XYL  been  forgotten?  No,  Sir!  Plans  for  her  en- 
tertainment are  high  in  priority.  XYL  activities  are  being 
planned  by  XYLs,  and  many  acti%dties  outside  of  ham  radio 
will  make  her  stay  as  pleasant  as  possible.  A  handsome  gift 
will  be  presented  to  each  lady  registering. 

The  registration  fee  is  $3.50  in  advance  and  $4.00  at  the 
door.  Advance  registrations  close  to  October  7th,  and  the 
committee  will  take  care  of  your  liousing  arrangements,  too!

FEDERAL  COMMUNICATIONS  COMMISSION 
Washington  25,  D.  C. 

Editor,  QiST: 

Because  it  concerns  a  rule  which  appears  to  have 
been  widely  misunderstood  as  to  its  correct  applica- 
tion, we  are  requesting  your  cooperation  in  giving 
publicity  to  this  letter. 

Section  12.113  of  Part  12,  Rules  Governing  Ama- 
teur Radio  Service,  specifies  that:  "Sideband  fre- 
quencies resulting  from  keying  or  modulating  a 
carrier  wave  shall  be  confined  within  the  authorized 
amateur  band."  This  appUes  to  all  amateur  fre- 
quency bands  allocated  for  telephony  emissions. 
Radiation  of  normal  or  spurious  sideband  fre- 
quencies, resulting  from  modulation,  outside  tlie 
amateur  telephony  bands  is  in  violation  of  Section 
12.113  regardless  of  whether  such  radiation  is  on 
frequencies  allocated  to  the  Amateur  Service  or  to 
other  radio  services. 

Questions  as  to  what  operating  carrier  frequency 
near  the  edge  of  a  telephony  band  would  assure  that 
transmissions  would  be  in  compliance  with  Section 
12.113  cannot  be  answered  in  terms  of  a  specific 
carrier  frequency.  Obviously,  the  characteristics  of 
the  voice  modulating  the  transmitter  and  the 
operational  characteristics  of  the  transmitter  itself 
determine  the  bandwidth  of  emission.  At  the 
present  time,  it  is  believed  that  the  exact  specifica- 
tion of  allowable  bandwidths  for  amateur  telephony 
together  with  the  necessary  specification  of  meas- 
uring equipment  and  techniques  would  introduce 
unnecessary  and,  therefore,  undesirable  complica- 
tion of  the  Amateur  Rules. 

It  is  the  responsibility  of  €»ch  operator  of  an 
amateur  station  to  make  sure  that  the  operation 
of  his  station  is  within  the  requirements  of  Section 
12.113.  That  part  of  Section  12.133  which  states 
that  "This  spurious  radiation  shall  not  be  of  suf- 
ficient intensity  to  cause  interference  in  receiving 
equipment  of  good  engineering  design  including 
adequate  selectivity  characteristics,  which  is  tuned 
to  a  frequency  or  frequencies  outside  the  frequency 
band  .  .  ."  is  considered  applicable  to  the  deter- 
mination of  compliance  with  Section  12.113. 

If  operation  near  either  edge  of  an  amateur  te- 
lephony band  is  contemplated,  all  amateurs  are 
cautioned  that  radiation  of  energj'  outside  the  band 
to  the  degree  indicated  in  Section  12.133  will  be 
considered  to  be  in  violation  of  Section  12.113, 
whether  double-sideband  full-carrier  or  single-side- 
band suppressed-carrier  is  used. 

Very  truly  yours,

A  Modern  Medium-Power  Transmitter 

The  4-65A  in  a  Multiband  VFO  Rig 

BY  RICHARD  A.  EGBERT,*   W8ETU.  EX-W2QMO 


•  Built  with  an  eye  primarily  on  contest 
competition,  this  neat  piece  of  construc- 
tion comhines  features  that  will  appeal 
to  all  types  of  operators.  Designed  around 
the  versatile  t-65A.  it  will  operate  effi- 
ciently at  any  plate  voltage  from  600  to 
2000  or  more,  at  inputs  from  90  watts  or 
less  up  to  .300  watts.  Features  include  re- 
mote-tuning VFO.  handpass-coupled 
multiplier  stages,  multihand  driver  tun- 
ing, pi-section  output,  and  differential 
keying  for  clean  hreak-in  operation. 
Covers  all  hands  fr.mi  80  through  10. 


THE  urge  to  rebuild  and  improve  the  station 
equipment  periodically  hits  us  all.  In  the 
author's  case,  this  urge  was  brought  about  b\- 
the  trend  in  the  local  amateur  radio  club,  The 
Order  of  Boiled  Owls,  toward  the  more  serious 
amateur  activities,  such  as  Sweepstakes,  DX 
contests,  and  a  generally  competitive  program. 
Since  the  main  transmitter  at  \V2QM0  was  a 
far  cry  from  what  is  needed  in  the  way  of  a 
tran.  mitter  for  contests  and  the  like,  several 
lequirements  for  what  we  thought  would  make 
:i  truly  modern  rig  were  written  down.  It  was 
iVlt  that  the  new  rig  should  be  capable  of  the 
lV)llos\-ing:  .   j      • 

1)  Respectable     power     output     by     toaay  s 

standards. 

2)  Full  break-in  operation. 

3)  Excellent  keying  characteristics. 

4)  Absolute  freedom  from  TVI.

.5)  Safety  from  electrical  shock  in  the  course  of 
normal  operation. 

fj)  Minimum  fus.sing  to  get  from  one  band  to 

another. 

7)  Pleasing,  commercial  appearance. 

The  usual  perusal  through  recent  issues  of  QST 
and  other  magazines  failed  to  turn  up  a  design 
that  quite  fitted  the  above,  but  many  good  fea- 
tures were  noted,  some  of  which  have  been  in- 
corporated in  the  transmitter  to  be  described. 
The  rig  shown  in  the  accompanying  photographs 
has  been  in  constant  operation  for  more  than  a 
year,  with  results  that  have  more  than  justified 
the  time  and  effort  expended  in  building  it. 

The  Circuit 

I'ig    1  shows  the  schematic  circuit,  beginning 
with  the  familiar  Clapp  oscillator.  The  oscillator 
tuned  circuit,  padders,  and  feed-back  capacitors 
are  mounted  in  a  separate  5  X  6  X  9-inch  alumi- 
num utilitv  box,    and   connected  to  the  mam 
transmitter  chassis  by  a  six-foot  length  of  R(- 
92 /U  cable  This  arrangement,  as  introduced  ami 
discussed  in  previous  issues  of  Q^T,'  has  proved 
to  be  a  sure-fire  method  of  building  an  oscillator 
that  "sits  still"  almost  from  the  moment  it  is 
turned  on.  There  is  nothing  more  disconcerting 
than  working  in  a  net,  or  sweating  out  DX,  with 
a  VFO  that  wanders  for  a  number  of  hours  before 
settling  dov\-n.  With  the  VFO  tuned  circuit  apart 
from  the  main  portion  of  the  transmitter,  anc 
kept  a  reasonable  distance  from  other  sources  ot 
heat    the   oscillator   frequency   becomes   st^able 
verv'  soon  after  the  rig  is  turned  on.  As  with  all 
oscillators,    the    quality   of    the   components   in 
the  fiequencv-determining  circuits  should  be  the 
highest  possible,  and  the  construction  rigid.

The  oscillator  tube,  a  6AH6,  was  chosen  after 
a  struggle  wath  the  types  that  are  more  usually- 
used  in  this  service.  One  of  the  requirements  tor 
the  keying  circuit  employed  is  that  the  oscillator 
start  with  as  little  delay  as  possible  after  the  key 
is  closed.  Since  the  feed-back  to  the  oscillator  is 
low,  due  to  the  high  values  of  d  and  C5  and  the 
L/C  ratio  used,  plus  the  capacitance  of  the  length 
of  RG-22/U,  a  tube  with  a  high  value  of  trans- 
conductance    must    be    used.    In    the    so-caUed 
electron-coupled  type  of  circuit,  the  screen  grid 
is  used  as  the  principal  anode,  instead  ot  the 
plate,   and  the  transconductance  we're  talking 
about  is  the  grid-to-screen  transconductance.  Al- 
though the  6AG7  is  the  most  frequently  used 
oscillator  tube  these  da>-s,  it  did  not  perform  well 
in  this  circuit.  The  5763  was  also  tried  but,  vnth 
either  tube,  the  oscillator  did  not  start  quickly 
enough,  and  the  output  signal  was  chirpy.  AH 
other  things  being  equal,  the  6AH6  seems  to  be 
the  best  of  the  bunch  for  the  job,  and  further 
work  along  these  lines  is  contemplated. 

The  oscillator  operates  in  the  80-meter  band, 
and  is  switched  to  either  of  two  ranges  by^i- 
With  Si  closed,  the  oscillator  tunes  from  3_5  to 
3  75  I^Ic.  and  when  Si  is  open,  the  range  is  from 
about  3.75  to  4.0  Mc.  This  arrangement  pro- 
vides 180  degrees  of  bandspread  on  80-meter 
c  w.,  nearly  135  degrees  on  40  meters,  90  degrees 
on  20,  and  about  75  degrees  on  the  15-meter  band 
The  10-meter  band  is  spread  over  most  of  the  dial 
and,  in  the  second-range  position,  the  75-meter 
'phone  band  occupies  almost  all  of  the  dial,  ^\lth 
the  5-to-l  ratio  of  the  National  ACN  dial,  tunmg 
is  quite  easy.  ^

A  6C4  cathode  follower  isolates  the  oscillator 
from  subsequent  stages,  and  its  output  is  more 
than  adequate  to  drive  the  6AK6  80-meter  stage. 
L2  in  the  grid  circuit  of  the  6AK6,  is  tuned  to  a 
frequency  slightly  higher  than  4.0  Mc.  This  ad- 
justment provides  fairly  constant  drive  to  the 
6\K6,  since  the  output  from  the  Clapp  oscillator 
falls  off  very  seriously  as  the  circuit  is  tuned  higher 
in  frequency. 

Quick  and  easy  frequency  changing  in  a  trans- 
mitter dictates  the  use  of  fixed-tuned  cu-cuits 
%vherever  possible.  Having  to  search  through  pUes 
of  charts  for  the  proper  multiplier-control  settmgs, 
and  adjusting  numerous  controls  is  hardly  easy 
operation.  Loaded,  broadband  inductors  eUim- 
nate  the  need  for  tuning,  but  result  m  wide 
variations  in  output  from  the  stages  usmg  them 
\vhen  the  frequency  is  shifted  appreciably.  In 
addition,  self-oscillation  sometimes  occurs  in  the 
multiplier  stages  at  some  frequency  between  the 
center  frequencies  of  two  of  the  coils. 

\lthough  not  new  by  any  means,  the  bandpass 
coupler  has  been  sadly  neglected  by  the  amateur 
fraternity  as  a  means  of  having  one's  cake  arid 
eating  it  too.^  The  bandpass  coupler,  if  properly 
used  can  be  made  to  provide  uniform  output 
over'an  entire  amateur  band.  Because  the  coup- 
hng  is  inductive,  rather  than  capacitive,  and  smce 
there  are  two  tuned  circuits,  rather  than  one,  a 
measure  of  protection  against  transfer  of  un- 
vvanted  harmonics  is  provided.  The  bandpass 
couplers  are  adjusted  as  described  later,  and  then 
sv^dtched  in  and  out  of  the  circuit,  as  needed, 
^yithout  further  adjustment.  As  it  turns  out,  the 
switching  scheme  of  this  transmitter  is  quite  a 
bit  more  simple  than  one  would  e.xpect,  smce  it  is 
accomplished  with  a  3-pole,  4-position  switch. 

Except  for  the  bandpass  couplers,  the  multi- 
plier stages  are  conventional,  mth  cathode  bias 
to  Umit  the  plate  dissipation  of  the  tubes  not  in 
use  at  anv  given  time.  One  of  the  6C4s  is  a  tripler, 
to  provide  output  on  15  meters.  The  other  two 
are  doublers. 

For  the  purist,  a  small  ceramic  trimmer  capaci- 
tor could  be  connected  from  grid  to  ground  in 
each  of  the  multiplier  stages,  since  the  input 
capacitance  of  the  6C4s  is  somewhat  lower  than 
that  of  the  pentode  driver,  and  some  change  in 
the  coupler  secondary  tuning  occurs  when  switch- 
ing from  a  multiplier  grid  to  the  driver  grid. 

The  driver,  a  5763,  is  driven  on  80  meters  by 
the  6\K6,  and  on  all  other  bands  by  one  of  the 
multipliers.  The  screen  voltage  to  the  5/63  is 
suppUed  from  a  potentiometer,  Ri,  which  con- 
trols the  output  of  the  driver  stage,  and  cons^ 
Quentlv  the  drive  to  the  final  amphfier.  The  5/63 
is  shunt  fed  in  its  plate  cucuit,  and  its  output  is 
capacitively  coupled  to  a  multiband  tuner  m 
the  grid  of  the  final  amplifier. 

The  driver  operates  straight  through  on  all 
bands  except  10  meters.  It  is  driven  by  the  20-. 
meter  multiplier,  and  doubles  to  10  nieters  foj 
output  in  the  10-meter  band.  Adequate  output 
from  the  driver  is  available  on  all  bands  to  dnve 
the  final  amplifier  to  full  output.  .  , 

The  pi-section  tank  circuit  is  a  good  choice  in

any  transmitter,  but  where  the  voltages  are 
high  enough  to  be  extremely  dangerous,  it  is 
literally  a  lifesaver.  No  need  to  put  one's  hands 
inside  the  transmitter  during  normal  operation 
as  with  plug-in  coils,  and  the  additional  harmonic 
attenuation  and  operating  ease  afforded  by  the 
pi  network  makes  this  type  of  final-amplifier 
tank  circuit  very  desirable  indeed. 

The  final  amplifier  shown  in  the  schematic 
diagram  and  photographs  is,  with  the  exception 
of  the  tube  type,  almost  an  exact  duplication  of 
one  described  in  an  earlier  issue  of  QST.*  It  was 
found  unnecessary^  to  neutralize  the  final  in  our 
particular  layout,  since  the  amplifier  was  stable 
on  all  bands.  Although  not  shown  in  the  schematic, 
a  parasitic  suppressor  is  used  in  the  plate  lead  of 
the  4-65A,  to  rid  the  transmitter  of  the  inevitable 
v.h.f.  parasitic. 

The  final-amplifier  tube,  a  4-65A,  was  chosen 
because  of  its  reputation  for  stability  and  rug- 
gedness,  and  its  ability  to  operate  efficientlj'  at 
plate  voltages  from  600  to  3000  volts.  At  a  plate 
voltage  of  2000  volts,  it  is  possible  to  load  the 
final  to  an  input  of  300  watts. 

Li4  is  a  rotary  inductor  whose  origin  is  mi- 
known,  but  whose  inductance  turned  out  to  be 
just  what  was  needed.  It  is  considerably  larger, 
physically,  than  is  necessary  in  a  transmitter  of 
this  size,  and  one  of  the  smaller  commercial  vmits 
could  be  used  instead.  Lu,  an  air-wound  inductor, 
constitutes  nearly  all  of  the  tank  inductance  when 
the  transmitter  operates  on  10  meters,  and  its 
inclusion  shifts  the  shunt  capacitance  of  the  ro- 
tary inductor  to  the  output  side  of  the  pi  network,

mica  capacitor,  Cie,  and  a  few  turns  of  wire,  Lis, 
is  connected  across  the  output  of  the  transmitter, 
at  the  output  connector.  This  series-tuned  circuit 
is  adjusted  to  resonate  at  the  frequency  of  the 
television  channel  most  likely  to  be  interfered 
with  in  a  given  locahtj',  and  is  effectively  a  short 
circuit  across  the  transmitter  output  at  this  fre- 
quencj'.  Thus,  any  harmonics  generated  within 
the  transmitter  at,  for  example,  50  Mc,  are 
prevented  from  reaching  the  antenna. 

Screen  voltage  to  the  final  amplifier  tube  is 
supplied  through  a  dropping  resistor,  and  the 
tube  is  protected  in  the  usual  manner  with  a 
()W6GT  clamp  tube.  Two  clamp  tubes  in  parallel 
would  afford  better  protection,  in  the  event  of 
failure  of  one  of  them.  The  0B2  voltage-regulator 
tube  is  connected  in  series  with  the  screen  lead 
of  the  4-65 A  to  reduce  the  input  to  minimum 
under  key-up  conditions.  The  0B2  can  be  seen 
mounted  on  a  bracket  under  the  chassis.  (It  was 
an  afterthought.) 

Keying 

As  shown  in  the  schematic,  the 
transmitter  is  equipped  with  a  built-in 
differential  kej'er.  For  those  who  are 
not  familiar  with  differential  kejdng,  it 
ma3'  seem  to  be  excess  baggage. 
This  is  not  at  all  the  case.  Much  of 
the  break-in  operation  on  the  air 
today  is  accomplished  liy  keying  the 


■J'he  VFO  remote  tuning  unit  and 
control  box.  The  tuning  unit  is  enclosed 
in  a  5  X  6  X  9-inch  ahuninum  box 
mounted  on  shock  absorbers.  The  con- 
trol-unit enclosure  is  made  up  of  two 
T  X  9  X  2-inch  aluminum  chassis,  bot- 
tom to  bottom.  The  range-control 
switch  and  remote  cable  connector  are 
mounted  on  one  end  of  the  tuning  unit. 
A  fuse  holder  projects  from  the  end  of 
the  control  unit.

oscillator.    Fortunately,    the    Clapp    oscillator, 
which  is  now  almost  universally  in  use,  keys  bet- 
ter than  its  forerunners,  but  there  aren't  many 
kej-ed  oscillators  that  can  be  boasted  about  when 
compared  to  a  keyed  amplifier.  For  the  ham  who 
takes  pride  in  his  signal,  oscillator  keymg  of  any 
kind  is  pretty  much  out  of  the  question.  Of  course, 
break-in  operation  can  be  had  by  using  a  well- 
shielded  oscillator,  left  running  while  keymg  a 
later  stage,  or  by  using  some  form  of  heterodyne 
exciter.  These  two  schemes  are  certainly  work- 
able, but  present  problems  that  are  not  easily 
overcome  by  the   average  ham.   Many  of  the 
differential   keying  arrangements  require   high- 
voltage    bias    supplies    and    high-priced    relays. 
Some  time  ago,  an  article,  in  QST°  descnbed  a 
keyer  circuit  that  needs  only  75  volts  of  negative 
bias,  and  no  relays.  It  is  this  keyer  that  is  incor- 
porated into  the  rig  being  described.  The  extra 
components  involved  are  few  and  inexpensive, 
and  good  ampUfier  keying  can  be  had,  with  all  the 
conveniences  of  the  keyed  oscillator. 

The  keyer  circuit  consists  of  a  twin-tnode  os- 
cillator-switching tube,  and  another  twin  triode 
in  a  standard  vacuum-tube  keyer  circuit.  With 
the  key  up,  the  6BL7GT  is  cut  off,  and  the  cui-- 
rent  through  the  right-hand  section  of  the  12AU7 
is  limited  to  a  low  value  by  the  cathode  resistor. 
Ro  is  adjusted  to  provide  a  sufficiently  negative 
potential  at  the  plate  of  the  left  half  of  the 
12AU7  to  cut  the  oscillator  off.  When  the  key  is 
closed,  the  grid  of  the  right  half  of  the  12AU7  is 
grounded  immediately,  the  cathodes  assume  a 
low  positive  voltage,  the  gi'id  of  the  left  triode 
becomes  negative,  and  the  plate  of  the  left  half 
assumes  gi'ound  potential.  Thus,  in  a  very  short 
period  of  time,  the  oscillator  is  turned 
on.  The  resultant  cUck  generated  by  the 
oscillator  coming  on  quickly  is  not 
heard  in  the  output  because  the  charge 
accumulated  in  Cn  must  leak  off  to 
ground  through  Rs  before  the  6BL7GT

lays," QST,  September,  1953. 


conducts.  By  the  time  the  6BL7GT  is  conducting, 
and  the  signal  is  on  the  air,  the  click  generated 
by  the  oscillator  is  over  wdth. 

'  When  the  key  is  released,  the  grids  of  the 
6BLG7T  and  the  right  half  of  the  12AU7  will 
start  falling  to  the  bias-supply  voltage.  The 
6BL7GT  will  cut  off  first,  and  some  time  later  the 
voltage  across  the  key  will  get  to  a  sufficiently 
negative  value  for  the  left  half  of  the  12AU7  to 
conduct,  cutting  the  oscillator  off.  The  oscillator, 
therefore,  has  been  turned  on  before  the  ampli- 
fier (in  this  case,  the  driver)  is  keyed,  and  is 
turned  off  after  the  amplifier  has  stopped  deliver- 
ing power. 

The  keyer  bias-supply  transformer,  I2,  is 
simply  a  low-current  filament  transformer,  con- 
nected backwards,  with  its  6.3-volt  winding 
e.xcited  from  Ti,  and  its  primary  deHvering  115 
volts  to  a  selenium  rectifier,  CRi,  and  a  conven- 
tional resistance-capacitance  filter. 

Metering  is  necessary  only  in  the  final-amphfier 
grid  and  plate  circuits,  since  all  other  stages  are 
fixed  tuned.  Two  meters  are  employed  —  a  2-inch 
unit  MA  1,  mounted  under  the  chassis  to  measure 
grid' current,  and  a  3-inch  meter,  MAo,  on  the 
panel,  reading  plate  current. 

Connections  to  the  transmitter  are  made  via 
a  barrier  strip  mounted  on  the  rear  skirt  of  the 
chassis,  and  a  MiUen  safety  terminal  for  the  high 
voltage. 

Construction 

The  r.f.  section  of  the  transmitter,  witfi  the 

exception  of  the  oscillator  tuned  circuit,  is  built 

on     a    standard     13  X  17  X  3-inch    aluminum 

chassis,  with  a  lOH  X  19-inch  rack  panel.  All

of  the  mechanical  work  was  done  at  home,  in  the 
shack,  using  the  common  hand  tools  that  most 
hams  possess,  and  a  couple  of  chassis  punches. 
Most  of  the  details  are  readily  apparent  from  the 
photographs,  and  the  layout  is  quite  straight- 
forward and  conventional.  About  one-third  of  the 
main  chassis  is  taken  up  by  the  exciter  chassis. 
The  remainder  is  enclosed  in  a  "doghouse"  con- 
structed of  aluminum  sheet  and  angle,  and  fas- 
tened together  with  machine  screws.  The  enclos- 
ure is  approximately  10  by  10  by  7  inches. 

The  top-view  photograph  shows  most  of  the 
chassis  layout,  with  the  6AH6  oscillator  tube 
located  in  the  top  right-hand  corner  and  the 
cathode  follower  next  to  it  at  the  left.  Imme- 
diately to  the  left  of  the  cathode  follower  is  the 
12AU7  keyer  tube.  Directly  below  the  6AH6  is 
the  6AK6  80-meter  stage  and,  to  its  left,  the  40- 
meter  doubler.  The  15-meter  tripler  is  located 
behind  the  40-meter  stage,  and  the  20-meter 
doubler  to  its  right.  Arranged  to  the  right  and 
left  of  the  associated  tubes,  the  adjusting  screws 
for  the  bandpass  couplers  can  be  seen. 


The  multiband  tuner  used  in  the  grid  circuit 
of  the  final  amplifier  is  housed  in  a  3  X  4  X  5- 
inch  aluminum  utUity  box,  bolted  to  the  side 
of  the  final-amphfier  enclosure.  The  dial  drive  to 
this  unit  is  equipped  with  a  5-to-l  reduction 
mechanism  for  easier  tuning.  (A  National  AX  or 
AVD  driver  may  be  used  here.)  To  the  right  of 
the  multiband-tuner  box,  the  5763  driver  tube 
is  mounted,  with  the  6BL7GT  kc^er  tube  directly 
above  it. 

The  final-amplifier  components  are  mounted 
inside  the  enclosure,  and  arranged  for  short  leads 
and  panel  symmetry.  The  socket  for  the  4-65A  is 
mounted  above  the  chassis  on  short  spacers,  with 
holes  for  air  circulation  below  it.  By-pass  capaci- 
tors for  the  screen  and  heater  of  the  final  tube  are 
grounded  directly  below  the  respective  socket 
terminals,  with  suitable  ground  lugs  fastened  to 
the  chassis.  A  shielded  lead  from  the  multiband 
tuner  to  the  grid  terminal  of  the  4-65A  socket  is 
run  through  the  bottom  of  the  utility  box  and  the 
chassis  and  up  through  a  hole  in  the  chassis  di- 
rectly below  the  tube  socket. 


Top  view  of  W2QM0's  transmitter.  At  the  right,  from  left  to  right,  progressing  toward  the  bottom  are  the 
12AU7,  the  6C4  cathode  follower  and  the  6AH6,  the  40-meter  6C4  and  the  80-meter  6AK6,  the  15-  and  20/10- 
meter  6C4s,  the  6BL7GT,  and  the  5763.  The  6W6GT  clamper  tube  is  at  the  upper  left.  The  multiband  tuner  for 
the  5763  is  enclosed  in  the  box  fastened  against  the  final-amphfier  enclosure.  The  tank  capacitor  is  placed  so  that  its 
shaft  is  central  on  the  panel,  and  the  rotary  inductor  is  located  so  that  its  control  and  the  control  for  the  multiband 
tuner  are  symmetrical  in  respect  to  the  tank-capacitor  control.  The  turns  counter  for  the  rotary  inductor  is  geared  to 
the  coil  drive  shaft.  S3  and  the  mica  output  capacitors  are  off  the  left  rear  corner  of  the  inductor.  The  v.h.f.  series- 
resonated  circuit  is  mounted  against  the  rear  wall,  adjacent  to  the  output  connect.  A  copper  strap  connects  the  top  of 
RFCi  to  the  plate  cap  of  the  tube.

The  6W6GT  clamp  tube  is  mounted  in  front  of 
the  final-amplifier  enclosure  toward  the  right  side 
of  the  chassis.  Above  the  clamp  tube,  the  Veeder 
Root  counter  can  be  seen.  This  was  included  to 
provide  accurate  resetting  of  the  variable  induc- 
tor. The  counter  is  gear-driven  from  th(^  rotary- 
induction  shaft. 

The  bottom-view  photograph  shf)ws  the  com- 
ponent layout,  terminal  strip  and  connectors. 
Since  the  photographs  were  made,  a  fan  has  been 
mounted  below  the  final-amplifier  tube  socket, 
to  aid  in  cooling. 

Building  the  Bandpass  Couplers 

The  bandpass  couplers  started  life  as  i.f.  trans- 
formers. The  original  windings,  forms,  and  cans 
were  removed  and  discarded,  and  polj'styrene  coil 
forms,  1  inch  in  diameter  and  IH  inches  long, 
were  drilled  through  their  bottoms  to  be  mounted 
on  the  studs  that  project  from  between  the  air- 
padding  capacitors.  The  primarj'  windings  of  the 
80-  and  40-meter  coils  are  wound  at  the  bottom 
ends  of  the  forms  and  cemented  in  place  with  coil 


The  iiiiilliliand  Viiiii-r  used  between  the  driver  and 
final  amplifier  is  housed  in  a  3  X  4  X  5-inch  box  fastened 
to  the  side  wall  of  the  amplifier  enclosure.  The  5763 
and  6BL7  have  been  removed  in  this  view. 

dope.  After  the  dope  has  dried,  the  rest  of  the  coil 
form  is  sprinkled  with  talcum  powder,  and  a 
layer  of  cellophane  tape  is  woimd  around  it,  with 
the  adhesive  side  out.  On  the  stickj^  side,  the 
secondary  turns  are  wound  firmlj^,  but  not  so 
tightly  that  the  winding  can  not  be  slid  along  the 
form  for  adjustment.  The  ends  of  the  secondary 
windings  are  held  in  place  with  coil  dope,  applied 
carefully  so  that  the  whole  thing  doesn't  become 
cemented  to  the  form  so  that  the  secondary  can- 
not be  moved.  The  ends  of  the  windings  are  now 
soldered  to  the  capacitors,  and  the  80-  and  40- 
meter  couplers  are  complete. 

The  20-  and  15- meter  couplers  are  made  from 
Barker  &  Williamson  Miniductors,  lengths  of 
which  are  slid  inside  the  polystj'rene  coil  forms. 
The  forms  are  first  slit  with  a  fine  saw  to  permit 
the  ends  of  the  windings  to  come  out  radially. 
The  primary  windings  are  inserted  in  the  poly 
forms  first,  and  the  secondaries  are  slid  in  and  out 
as  needed  for  adjustment. 


This  photograph  shows  the  method  of  assembling 
the  bandpass  couplers  as  described  in  the  text. 

Power  Requirements 

Power  supplies  for  the  author's  transmitter 
were  built  on  a  single  13  X  17  X  3-inch  steel 
chassis.  Although  the  4-65A  will  operate  satis- 
factorily at  plate  potentials  from  600  to  3000 
volts,  at  least  2000  volts  is  necessary  for  an  input 
of  300  watts.  Ti  supplies  the  final-amplifier, 
clamp-tube,  the  GBL7  keyer-tube  heaters,  and  To, 
the  kej'er  bias  transformer.  The  balance  of  the 
heaters  are  supplied  from  a  replacement-type 
power  transformer,  rated  at  750  volts,  center- 
tapped,  and  6.3  volts  at  3.5  amperes. 

It  will  be  noticed  that  no  power  switches  appear 
on  the  transmitter  proper.  AH  switching  is  done  at 
a  central  control  panel,  located  beneath  the  VPO 
tuning  unit.  As  the  schematic  of  Fig.  2  shows,  115 
volts  a.c.  is  brought  into  an  automobile  ignition 
switch.  Si,  which  allows  the  entire  station  to  be 
shut  off  with  a  key.  Since  the  key  is  carried  in  the 
author's  pocket,  there  is  little  likeUhood  that  the 
junior  ops  will  get  their  little  fingers  across  the 
high  voltage.  The  switching  is  arranged  so  that  it 
is  necessary  for  the  exciter,  final  heaters  and  high-

Bottom  view  of  the  main  chassis  showing  the  grouping  of  the  handpass  couplers  around  the  handswitcli  in  tlie 
upper  left-hand  corner.  Rz,  the  bias-adjusting  potentiometer  for  the  v.t.  switch  circuit,  is  to  the  left  of  the  grid- 
current  milliammeter,  top  center.  The  0B2  in  the  4-65A  screen  circuit  is  mounted  on  a  bracket  below  the  meter.

voltage-rectifier  heaters  to  be  turned  on  before 
the  power  can  be  apphed  to  the  plate  transformer. 

The  switch,  S5,  a  d.p.d.t.  toggle,  is  the  usual 
spotting  switch,  which  grounds  the  key  lead 
and  opens  the  primarj'  circuit  of  the  plate  trans- 
former. 

The  power-control  panel  is  made  from  two 
7  X  9  X  2-inch  aluminum  chassis,  bolted  to- 
gether with  their  bottoms  facing,  with  most  of 
the  front  skirts  cut  away  to  receive  an  aluminum 
panel.  The  VFO  tuned-circuit  bo.x  is  mounted  on 
this  with  shock  mounts. 

Tuning  Up 

After  all  wiling  is  checked,  the  oscillator  tube 
and  cathode  follower  are  plugged  into  their 
sockets,  and  the  exciter  power  turned  on.  If  all 
is  well,  the  signal  will  be  heard  in  a  receiver,  in 
the  vicinity  of  the  80-meter  band.  Ne.xt,  Si  is 
opened,  Ci  set  at  minimum  capacitance,  and  Co 
adjusted  until  the  signal  is  heard  slightly  above 
4  Mc.  WTien  d,  is  set  at  maximum  capacitance, 
the  signal  should  be  found  in  the  vicinitj-  of  3.75 
Mc.  Si  should  now  be  closed,  and  C3  adjusted 
until  the  signal  is  heard  at  slightly  below  3.5  Mc. 
Some  Blight  pruning  of  the  tuned  circuits  may  be 


necessarjr,  but  it  should  be  possible  to  get  the 
oscillator  to  operate  from  below  3.5  Mc.  to  over 
4.0  Mc,  with  a  slight  overlap  around  3.75  Mc. 

Now  the  bandpass  couplers  can  be  tuned,  and 
this  takes  a  lot  more  time  to  tell  about  than  it 
does  to  accomphsh.  Set  the  bandswitch  in  the  80- 
meter  position,  the  excitation  control  at  zero, 
and  plug  in  the  rest  of  the  tubes  in  the  exciter 
section.  Temporarily  ground  the  cathode  of  the 
5763,  and  connect  a  high-resistance  voltmeter 
across  the  5763  grid-leak  resistor.  All  bandpass- 
coupler  secondary  windings  should  be  pulled  as 
far  away  from  the  primaries  as  possible.  The  VFO 
is  now  set  at  3.75  Mc,  and  Ce  and  C7  tuned  for 
maximum  indication  on  the  voltmeter.  The 
secondary  winding,  L4,  should  now  be  moved 
toward  L3,  until  the  spacing  is  that  given  in  the 
coil  table.  This  spacing  should  be  set  very  care- 
fully in  all  cases,  since  a  small  deviation  wiU  result 
in  a  change  in  the  bandpass  characteristic.  It  is 
also  to  be  noted  that  the  coupler  tuning  capacitors 
are  to  be  adjusted  only  when  the  windings  are  at 
the  maximum  spacing. 

Next,  move  the  high-resistance  voltmeter  to 
read  the  drop  across  the  6AK6  grid-leak  resistor 
and  set  the  VFO  frequency  at  4  Mc.  Now  adjust 


18 


QST  for 


/>2  for  maximum  grid  voltage,  and  swing  the  \'F0 
through  its  entire  range.  If  the  grid  voltage  in- 
creases when  the  frequenc}-  is  lowered,  decrease 
the  inductance  of  L2.  Correct  adjustment  of  L2 
will  result  in  nearlj'  constant  drive  to  the  6AK6 
throughout  the  entire  VFO  range. 

The  rest  of  the  bandpass  couplers  can  now 
he  adjusted,  following  the  procedure  described 
above  for  the  3.5-Mc.  coupler,  and  with  the  volt- 
meter once  again  reading  driver  grid  voltage.  The 
40-meter  coupler  should  be  adjusted  with  the  VFO 
set  at  3.6  Mc,  the  20-meter  coupler  should  be 
adjusted  at  3.6  Mc,  and  the  15-meter  coupler  at 
3.55  Mc.  It  should  now  be  possible  to  time 
through  anj'  of  the  bands  mth  less  than  ten  p^r 
cent  variation  in  drive  to  the  5763. 

The  multiband  tuner  can  now  be  checked,  with 
the  4-65A  in  its  socket,  and  heater  voltage  ap- 
plied. It  is  suggested  that  a  grid-dipper  be  used 
to  ascertain  that  the  grid  circuit  is  tuning  to  the 
proper  frequenc}'  and  not  to  a  harmonic.  Grid 
tuning-dial  settings  should  bo  logged  for  future 
reference,  and  note  taken  if  two  bands  resonate 
at  the  same  dial  setting.  If,  for  example,  the  80- 
and  20-motcr  resonance  points  occur  at  or  near 
the  same  dial  setting,  priming  of  one  of  the  coils 
will  be  necessarJ^ 

Adjustment  of  the  keyer  can  now  be  made 
after  removing  the  ground  from  the  5763  cathode. 
/?2  is  advanced  toward  its  positive  end  (ground) 
until  the  voltage  at  Pin  1  of  the  12AU7  is  —15 
volts.  The  kcAnng  characteristic  can  be  adjusted 
to  individual  taste  later  bv  adjusting  the  value 

of  C17. 


Pi-Tank  Adjustment 

The  final  amplifier  is  best  tested  at  reduced 
plate  voltage.  Either  a  50-ohm  dummy  load  or  an 
antenna  known  to  present  a  resistive  load  of  50 
ohms  should  be  used  for  initial  tune-up.  Adjust- 
ment of  the  excitation  control,  R\,  will  provide 
the  correct  grid  current  of  15  ma.  to  the  final. 
With  the  bandswitch  set  in  its  80-meter  position, 
and  the  grid  tank  resonated,  the  plate  tank 
capacitor,  C15,  should  be  set  at  about  90  per  cent 
of  its  maximum  value,  and  the  rotary  inductor 
set  at  near-maximum  inductance.  A  grid-dipper 
could  be  used  here  to  establish  a  near-resonance 
point.  The  plate  voltage  should  be  applied,  and 
Ci5  quickly  tuned  for  a  plate-current  dip.  If  an 
appreciable  change  in  capacitance  is  necessarj-  to 
establish  resonance,  a  new  setting  of  the  variable 
inductor  vshould  be  tried,  until  the  plate  circuit 
resonates  at  3.5  Mc.  with  almost  all  of  the  capaci- 
tance of  Ci5  in  the  circuit.  Full  plate  voltage  can 
now  be  applied,  and  loading  adjusted  for  a  plate 
current  of  150  ma.  Now  is  a  good  time  to  check 
the  4-65.\  screen  voltage,  which  should  be  250 
volts. 

Adjusting  the  final  amplifier  on  the  other  bands 
is  carried  on  in  much  the  same  manner,  setting 
the  final  tank  capacitor  to  approximately  the 
correct  value  (see  Table  II),  adjusting  the  rotary 
inductor  for  resonance  with  a  grid  dipper,  and 
finally  resonating  the  circuit  with  j^ower  on.  .Ml 
settings  should  be  logged  for  future  reference. 

It  must  be  borne  in  mind  that  the  values  of  in- 
ductance and  capacitance  given  in  the  tune-up

The  "Extended  Lazy  H"  Antenna 

BY  WALTER  E.   SALMON,*   VK2SA 


ROTYRY   BEAMS   Were   uukno\TO   in   the  early 
days  of  amateur  radio,   and  most  hams 
-  contented  themselves  with  horizontal  or 
vertical  mres  from  which,   after  much  patient 
work  thev  obtained  varying  degrees  of  ettective- 
ness  "with  the  development  of  the  Yagi  antenna 
the  2-  3-  and  4-element  rotary  beam  became  com- 
monplace, and  it  would  appear  that  the  trend  in 
this  direction  is  increasing,  particularly  with  ama- 
teurs residing  in  thickly-populated  areas  where 
land  space  is  limited.  No  comment  ^n\\  be  in- 
cluded about  V  beams  and  rhombics,  since  this 
article  is  written  for  the  amateur  who,  although 
he  is  interested  in  operating  on  several  bands, 
is  not  prepared  to  erect  a  costly  mast  structure 
to  support  several  beams  and  also  does  not  have 
the  relatively-unUmited  space  necessary  for  the 
usual  "dream"  antenna  farm. 

The  antenna  to  be  described  is  completely 
original  and  to  the  writer's  knowledge  has  not 
been  described  in  any  local  or  overseas  journa  . 
We  have  "ZL  Specials"  and  "G8P0  antennas 
and  for  want  of  a  name,  this  antenna  might  be 
caUed   the   "extended  lazy   H."    Several   years 
aeo  a  conventional  lazy  H  antenna  was  cut  tor 
14  Mc   and  installed  at  VK2SA.  This  aenal  con- 
sisted of  two  horizontal  coUinear  elements  stacked 
and  separated  a  half  wavelength.  The  top  of  the 
array  was  supported  by  two  41-foot  masts,  thus 
leaving  the  bottom  section  only  9  feet  above  the 
ground   The  effective  height  of  this  type  of  an- 
tenna is  measured  from  the  halfway  pomt  be- 
tween top  and  bottom  elements  and  thus,  m  this 
case  the  effective  height  was  about  25  feet    ihe 
observed  effectiveness  was  only  about  equal  to  a 
full-wave  Zepp  41  feet  high. 

Attention  was  then  directed  to  the  possibilities 
of   the    "extended   double    Zepp"    described  in 
QST  for  June,  1938.  The  height  of  one  mast  was 
increased  to  45  feet,  to  compensate  for  ground 
slope,  and  the  antenna  was  cut  for  14  Mc    and 
erected   for   NE-SW   directivity.    Improved   ef- 
fectiveness by   comparison   with  the  full-wave 
antenna  was  apparent  on  14-Mc.  W  contacts. 
In  addition,  some  excellent  'phone  contacts  were 
made  on  7  Mc.  wnth  W  stations.  Results  on  21 
Mc  indicated  a  number  of  major  lobes  that  gave 
good  DX  contacts.  From  the  results  it  would 
appear  that  this  type  of  antenna  possesses  the 
desirable  feature  of  good  effectiveness  on  several 
amateur  bands.  The  gain  of  the  extended  double 
Zepp  is  given  in  most  textbooks  as  3  db. 

The  theoretical  gain  of  the  conventional  lazy

and  one  would  normally  connect  half-wavelength  elements 
at  thl  point  for  in-phase  drive  of  all  elements.  The  modifica- 
S.n  by  VK2SA  is  not  the  simplest  array  to  analyze,  but  in 
S  of  his  excellent  results  it  is  thought  to  be  of  considerable 
interest.  — Ed. 


H  antenna  is  given  as  close  to  6  db.,  but  it  was 
considered  attainable  only  if  it  could  be  supported 
about  70  feet  in  the  air,  so  that  the  bottom  ele- 
ments were  at  least  a  half  wavelength  above 
ground.  This  was  impossible  with  the  existing 
masts.  Consideration  was  then  given  to  the  pos- 
sibility of  adding  two  additional  extended  hall- 
wave  lower  elements  to  the  extended  double 
Zepp    The  additional  elements  were  connected

good  general  coverage.  On  7,  14  and  21  Mc  an 
antenna  tuner  is  used,  and  an  open-wire  hne 
with  4-inch  spacing  is  used  between  tuner  and 

^  On  14  Mc.  the  antenna  has  outperformed  all 
previous  wire  antennas  tried  out  for  W  contacts 
on  both  long  and  short  paths.  The  lower  two  ele- 
ments were  added  to  the  extended  double  Zepp 
on  December  19,  1954,  and  numerous  W  phone 
contacts  have  been  made  since  that  date,  ihe 
majority  of  the  signal  reports  are  S8  and  by 
and  nothing  below  S6  from  East  Africa.  The 
power  input  to  the  transmitter  is  /5  watts 

An  analysis  of  all  signal  reports  mdicates 
equal  if  not  better  performance  compared  with 
rotary  beams,  and  it  would  appear  that  the  gam 
exceeds  6  db.  Comparison  reports  have  also  been 
made  by  the  simple  expedient  of  removing  the 
two  lower  elements  -  the  antenna  then  becomes 
an  extended  double  Zepp  -  and  the  signal  was 
reported  to  drop  2  and  sometimes  3  b  points.

The  Simplest  Converter 

A  One-Tube  Design  for  Reception  on  15,  10,  6,  2  or  1  1/4  Meters 
BY  MASON  P.  SOUTHWORTH,  WIVLH 


•  A  common  request  slio^ving  up  in  mail 
for  the  ARRL  Technical  Information 
Service  in  recent  years  has  been,  ^AXheie 
can  I  find  information  on  a  simple  con- 
verter for  21.  28,  50  or  114  Mc,  not 
cryslal-conlrolled?"  Seems  that  there 
are  plenty  of  beginners,  and  not  a  few 
old-timers  too,  ^vho  want  to  receive  on 
one  or  more  of  these  bands  without 
going  to  something  complicated  or 
tough  to  build.  Here's  the  answer,  and 
then  some  — a  one-tuber  that  Provides 
usable  reception  on  21,  28,  50,  144  or  220 
Mc.  You  can  cover  15,  11  and  10  meters 
without  changing  coils. 


TO  a  fellow  getting  started  in  ham  radio,  or 
even  some  new  phase  of  the  game,  life  can 
seem   pretty   compUcated   at   times.    A  lot 
of  the  gear  described  in  the  magazines  looks  very 
nice  and  undoubtedly  works  well,  but  is  just  too 
complicated  or  takes  too  many  hard-earned  parts 
for  beginners  to  think  about  buildmg  it.  Here  s 
a  converter  that  was  designed  with  these  fellows 
in  mind.  It  uses  as  few  parts  as  is  practical  and 
construction  is  simple  and  straightforward.   It 
also  covers  a  lot  of  territory.  You  can  build  it 
for  21    28,  50,  144  or  220  Mc.  You  can  use  it  to 
listen  'in  on  any  v.h.f .  band,  or  to  improve  your 
reception  on  15  or  10  meters,  where  many  of  the 
lower-priced  commercial  receivers  fall  short.  The 
output  frequency  can  be  anywhere  in  the  40- 
meter    region,    and    almost    any    receiver    that 
tunes  this  range  will  do  for  the  i.f.  system 


You  ma>-   have  noticed   that  we  haven't  re- 
fmred  to  this  design  as  a  multiband  converter. 
You  just  can't  have  all  those  bands  at  once  and 
simplicitv    too.    Wide    freciuency    coverage    by 
means  of  switching  or  plug-in  coils  nearly  always 
involves  performance  compromises,  even  at  50 
Mc,  and  it  is  practically  out  of  the  question  for 
144  or  220  Mc.  Bandchanging  in  this  case  is 
accomplished  by  removing  two  coUs  and  soldermg 
in  a  new  pair.  This  approach  doesn't  lend  itselt 
to  hopping  around  the  spectrum,  but  it's  hard 
to  beat  for  simphcity  and  performance  on  any 
one  band.  Four  coil  sets  are  shown.  One  pair 
covers  15   11  and  10  meters  while  the  other  three 
sets  are  for  6,  2  and  1^-  H  the  thought  of  solder- 
ing and  unsoldering  worries  you,  the  converter 
is  so  simple  that  you  can  always  build  another 
for  a  second  favorite  band. 

Perhaps  the  best  way  to  describe  a  piece  ot 
gear  like  this  is  to  state  what  it  wUl  do  and  what 
it  won't   It  will  give  usable  reception  on  all  the 
above  bands.  The  noise  figure  does  not  represent 
the  ultimate  by  any  means,  but  you  wUl  hear  al 
but  the  weaker  ones  on  144  and  220  Mc     and 
sensitivity  on  the  lower  bands  wUl  equal  that  ot 
all  but  the  best  communications  receivers,  btabil- 
ity  is  satisfactory  after  a  warm-up  period:  good 
enough  for  c.w.  reception,  even  on  144  Mc.  Image 
rejection  is  low  on  144  and  220  Mc,  of  course 
but    this    is    not    often    troublesome    m    actual 
operation.    If   this   sounds   Uke   something   you 
could  use,  let's  see  how  little  it  takes  to  do  the

receiver  instruction  book  for  the  required  plug 
connections. 

The  various  components  visible  in  the  bottom 
view  have  been  labeled  for  ease  in  identification. 
Most  of  the  small  parts  are  grouped  around  the 
tube  socket  near  the  renter  of  the  chassis.  There 
is  ver>-  little  firing  to  be  done  other  than  solder- 
ing in  these  resistors  and  capacitors  by  their 
leads.  Below  the  tube  socket  are  the  slug-tuned 
Ls  and  a  two-terminal  tie  point  supporting  i?4. 
Lz  is  held  in  place  bj^  passing  its  leads  through 
holes  in  the  plastic  rings  supplied  with  the  XR-91 
coil  form.  L4  is  wound  around  the  by-passed  end 
of  Lz  and  is  cemented  or  doped  in  place.  Its  leads 
are  then  twisted  and  run  over  to  the  output 
connector  on  the  back  of  the  chassis.  If  the  dual 
connector  shown  is  not  available,  two  standard 
phono  jacks  can,  of  course,  be  substituted. 

The  mixer  grid  circuit  is  visible  above  and  to 
the  left  of  the  tube  socket.  Ci  is  mounted  on  the 
front  wall  of  the  chassis  and  Li  is  soldered  across 
its  terminals.  A  short  piece  of  coax  (RG-58,  U 
or  RG-59/U)  is  run  from  the  input  connector 
to  the  grid  circuit.  Here  the  braid  is  grounded  to 
the  rotor  of  Ci  and  the  inner  conductor  is  tapped 
onto  Li  in  the  proper  place.  Note  the  two  ^-inch 
holes  drilled  between  the  tube  socket  and  the 
tuning  capacitor.  These  are  for  the  leads  from 
d  and  Pin  1  of  the  6J6.  These  should  pass 
through  the  chassis  near  the  centers  of  the  holes. 
The  tube  socket  should  be  mounted  as  shown 
with  Pin  1  adjacent  to  the  large  hole  near  the 
middle  of  the  chassis. 

The  third  photograph  shows  the  coils  for  15, 
10,  6  and  134  meters,  the  2-meter  coils  being  on 
the  converter  when  the  pictures  were  made. 
The  oscillator  coils  with  their  trimmers  (Cs)  and 
decoupling  resistors  (R3)  are  in  the  back  row,  and 
the  mixer  grid  coils  are  in  the  front  row.  It  is  not 
necessary  to  use  separate  trimmers  for  each 
oscillator  coil,  of  course,  but  doing  this  eliminates 
the  need  for  readjustment  when  changing  coils. 
The  use  of  separate  decoupling  resistors  does 
away  with  repeated  soldering  to  the  coil  center

tap.  The  coils  for  50  Mc.  and  below  are  made  of 
sections  of  B  &  W  Miniductor.  It  will  be  easier 
to  solder  to  these  if  the  turns  each  side  of  the 
desired  one  are  bent  toward  the  center  of  the 
coil.  The  higher  frequency  coils  are  made  from 
No.  14  wire  as  described  in  the  parts  list. 

The  oscillator  capacitor,  Ce,  was  modified 
slightly  to  secure  more  bandspread  on  the  higher 
ranges.  The  end  stator  plate  and  the  last  two 
rotor  plates  of  each  section  should  be  removed 
by  twisting  carefully  with  long-nosed  pliers.  This 
leaves  four  stator  and  three  rotor  plates  in  each 
section.  If  the  converter  is  to  be  used  on  144

Wait  and  See 


BY  ROBERT  D.  REED  *  W5KY 


PEOPLE  have  a  peculiar  ability  which  probably 
is  the  world's  best  method  for  an  adult  to 
get  his  left  foot  into  his  right  ear  by  waj^  of 
his  mouth.  This  ability  combines  the  faculty  of 
speech  with  the  idea  that  firm  opinions  on  sub- 
jects are  not  only  necessary'  but  must  be  defended 
to  the  last  ditch,  the  last  shell,  and  the  last  807. 

Genus  Homo  Sapiens  {sub-phylum  Hammus 
Electronicii  Radioicus)  is  particularly  adept  at 
having  opinions  plus  the  ability  to  spray  them 
loudly  over  the  world  by  virtue  of  his  super 
blaster-band  ear  buster  nmning  a  jillion  watts  to 
a  whang-doodler  of  an  antenna  which  has  major 
lobes  in  360  directions.  Defense  of  said  ideas  and 
opinions  may  be  audible  or  b}^  certain  rhj'thmic 
undulations  of  the  fingers  in  cooperation  with  a 
key. 

It  is  a  brave  man  who  approaches  JIamraus 
with  the  idea  of  changing  his  opinion  on:  (1)  pol- 
itics, (2)  religion,  (3)  the  peerless  qualities  of  his 
children,  (4)  the  fire-snorting  dash  and  perform- 
ance of  his  Detroit  gasoline-burner  eight,  (5)  the 
best  wa}^  to  enhance  further  the  state  of  ham- 
band  QRM,  and  (6)  either  side  of  the  s.s.h.  vs.  a.m. 
controversy.  The  amateurs  doing  the  most  and 
best  with  their  hobby,  we  think,  are  those  keep- 
ing clear  of  the  fray.  .  .  .  It's  best  of  all  to  wait 
and  see. 

He  who  ventures  forth  on  any  of  the  items 
from  (1)  through  (5)  is  the  victim  of  simple  as- 
sault and  can  usually  be  patched  up  with  some 
salve  and  a  few  bandages  placed  in  strategic 
spots.  But  that  number  (fi) !  ^Iurder  and  maj-hem 
are  mild  in  comparison  with  what  happens  to  the 
innocent  venturer  forth  on  that  subject.  His  an- 
tenna vanishes  in  a  cloud  of  green  smoke.  His  re- 
ceiver melts  into  a  blob  of  assorted  steel,  copper, 
glass  and  aluminum.  The  antenna  relaj'  breaks 
down  and  the  surge  into  his  transmitter  com- 
pletel}"  discombobulates  it  back  to  the  VFO. 

Old  Growler,  licensed  prior  to  1920,  sageh' 
nods  his  head  when  he  hears  such  goings  on.  Lis- 
ten carefulh'  as  he  mumbles  softlj'  to  himself. 
Long,  long  ago  he  learned  of  the  hazard?  of  speak- 
ing loudly  about  differences  of  opinion. 

Heh!  Heh!  Beats  all  how  history  repeats.  Like 
in  the  early  Twenties,  just  like  'em!  When  I  think 
how  brave  those  little  210s  and  VTls  and  VT2s 
were  as  they  looked  the  kilowatt  sparks  straight 
in  the  eye  with  their  innocent  little  chirps,  I'm 
surprised  all  over  again.  It  took  a  whale  of  a  lot  of 
convincing  for  me  to  get  it  into  my  thick  skull 
that  a  little  five-  or  ten-watt  chirp  could  nm 
circles  around  mj-  big  old  spark  rig.  It  didn't  seem 
possible  that  something  that  just  sat  there  and 
glowed  could  work.  Seemed  as  if  it  just  had  to 
make  some  noise.  But  I  was  young  then,  and 
pretty   dad-burned   stubborn.    (Got   my   come-

uppance  though  just  as  lots  of  young  fellows 
now-a-days  might  get  theirs.) 

Never  will  forget  the  night  that  Old  Joe  called 
me  on  the  land  line  to  ask  me  to  take  a  look  at 
his  new  210  rig.  It  was  cold  and  clear  and  signals 


SEEMED   IT  JUST  HAD 
TO  MAKE  SOME  NOISE 


were  rolling  in  like  mad.  Old  Joe  had  moved  his 
rig  into  the  kitchen,  now  that  the  rotarj'  gap 
didn't  make  so  much  household  QRM.  His  XYL 
met  me  at  the  door  and  took  me  to  the  kitchen 
where  Old  Joe  grinned  at  me  over  the  coffee  pot 
and  waved  me  to  a  chair  beside  him  as  he  threw 
the  switch  to  the  "transmit"  position. 

As  he  tapped  out  the  call  of  the  station  he  was 
working  I  nearly  fell  off  of  my  chair !  He  was  work- 
ing  more  than  1800  miles  with  that  quiet  little 
fugitive  from  an  electric  light  factory!  I  had 
thought  Old  Joe  was  kidding  but  I  sure  got  con- 
\nnced  when  he  turned  it  over  to  his  contact.  By 
gum,  he  was  in  contact  with  him ! 

I  had  planned  to  stay  just  a  little  while  and 
then  get  back  to  the  home  rig  to  stop  fooling 
around  and  work  some  DX.  Seems  funny  now 
but  DX  to  me  with  my  old  kilowatt  spark  was 
about  1000  miles.  This  business  of  working  1800 
miles  needed  looking  into.  So  I  looked,  but  did  I 
catch  it  from  the  XYL  when  I  got  home  in  the 
wee  small  hours.  She  even  smelled  my  breath  to 
verif}^  my  story. 

That  night  of  DX  in  the  pleasant  warmth  of 
the  kitchen  at  Old  Joe's  made  a  cautious  convert 
of  me  to  the  tune  of  a  210,  some  coils,  condensers 
and  such,  which  I  tied  to  my  antenna.  My  little 
chirp  added  to  those  already  hunting  for  better 
and  better  DX.  I  had  to  learn  to  tune  mj'  re- 
ceiver all  over  again  and  learn  how  to  get  away 
from  pesky  capacity  effects  which  came  as  I 
reached  for  the  dial  to  touch  up  the  receiver.  I 
learned!  But  in  the  meantime,  dust  began  to 
gather  on  the  old  spark  rig. 

After  a  few  weeks.  Old  Bill,  who  had  a  spark 
like  mine  across  town,  was  having  coffee  with  me 
at  the  local  beanery.  He  was  not  as  free  and  eas}' 
with  me  as  he  used  to  be.  I  found  out  what  was 
wrong  when  I  began  to  tell  him  about  that  inno- 
cent looking  little  210  and  the  contacts  I  was

from  the  driver's  seat. 

THE  writer  has  expended  his  share  of  time 
and  energj'  in  trjdng  out  the  usual  arrange- 
ments of  mobile  installation  —  transmitter 
under-dash  mounting  and  trunk  mounting,  an- 
tenna with  base  loading  and  center  loading, 
direct  couphng  and  the  tapped-coil  method 
(shunt  feed),  and  the  usual  array  of  tuning  slugs 
and  capacitive  hats.  The  result  was  considerable 
frustration  and  a  family  gas  buggj^  with  enough 
holes  in  the  body  to  make  a  car  dealer  shudder. 

For  ease  of  operation,  it  was  finally  decided 
that  the  transmitter  had  no  place  in  the  trunk, 
but  belonged  up  front  in  constant  range  of  the 
operator's  hand  and  eye.  Furthermore,  after 
shattering  an  overhead  fluorescent  lamp  in  a 
filling  station  one  night,  with  a  cowl-mounted 
job,  the  antenna  was  transferred  to  the  rear 
bumper  as  the  only  safe  place  for  an  8-ft.  whip. 

The  abilitj^  to  QSY  more  than  a  few  kilocycles 
on  any  band  with  such  an  arrangement  was  a 
hopeless  dream,  nursed  in  despair  for  a  long 
time.  The  usual  procedure  is  to  tune  up  before 
the  car  is  put  in  motion,  and  then  stop  a  couple 
of  times  to  adjust  the  antenna  to  compensate 
for  the  change  in  capacitance  as  the  wind  bows

the  whip  backward.  Wlien  it  is  desired  to  QSY, 
the  procedure  must  be  repeated.  (This  sort  of 
stuff  can  lead  to  divorce  if  the  XYL  is  along 
expecting  an  uninterrupted  Sunday  drive.) 

A  Convenient  Tuning  System 

The  remote  tuner  described  has  solved  this 
problem  well,  and  the  author  is  now  at  peace 
with  himself  and  the  familj^  No  cross  words 
from  the  XYL,  even  after  miles  of  rag-chewing 
on  75  meters.  The  antenna  is  tuned  by  a  variable 
inductor  connected  at  the  base  of  the  antenna, 
and  driven  remotely  from  the  driver's  seat  by 
means  of  a  flexible  shaft.  The  number  of  turns 
needed  to  cover  the  75-meter  band  is  so  small 
that  it  has  little  effect  on  the  performance  of 
a  center-loaded  antenna.  Some  commercially 
manufactured  tuners,  similar  in  principle,  em- 
ploy reversible  d.c.  motors  for  rotating  the  coil. 
If  a  suitable  motor  and  reduction  gears  are 
available,  fine,  but  for  economy  and  downright 
simplicity,  the  flexible  shaft  is  hard  to  beat. 

To  facilitate  accurate  and  easy  tuning,  a 
resonance  indicator  that  may  be  placed  within 
view  of  the  operator  is  included. 

The  tuning  mechanism  consists  of  the  rotocoil 
and  associated  rider,  springs  and  a  bakelite  strip 
taken  from  the  antenna  circuit  of  a  BC-696. 
Since  only  about  12  turns  are  required  to  cover 
the  band,  the  coil  from  a  BC-457  may  also  be 
used.  The  BC-696  is  often  converted  for  75-meter 
components  may  be  simply  transferred  from  the 
BC-696  to  the  antenna  tuning  unit.  A  coaxial

cable  is  then  used  between  the  antenna  tuner 
and  the  output  link  of  the  BC-696. 

The  BC-442  Command  antenna-relay  unit 
(another  available  surplus  item)  offers  a  meter 
with  an  external  thermocouple  that  can  be 
used  in  the  remote  resonance  indicator.  If  the 
mounting  plate  for  the  BC-442  can  also  be 
obtained,  it  makes  an  ideal  mounting  for  the 
tuning  unit  that  can  be  removed  simply  by 
releasing  the  four  slip  catches  which  clamp  on 
the  shock  mounts. 

Construction 

To  begin  the  construction,  completely  dis- 
mantle the  BC-442,  and  remove  the  studs  to 
which  the  cover  is  fastened,  by  twisting  them  out 
with  pliers.  The  studs  on  the  flanges  under  the 
base  plate  were  left  intact  so  that  a  cover  could 
be  mounted  over  the  assembh'  in  case  trouble 
developed  from  dirt  on  the  rider  contact.  So  far 
this  has  not  happened.  It  will  be  found  that 
when  the  coil  is  mounted  with  one  side  flush  with 
the  edge  of  the  base,  and  the  bakelite  mounting 
strip  for  the  rider  and  springs  is  mounted  about 
}4,  inch  in  from  the  opposite  side,  the  rider  will 
fit  the  coil  with  about  the  right  amount  of 
tension.  The  rider-spring  mounting  screws  pass 
nearly  through  the  bakelite  strip.  The  chance  of 
a  short  can  be  reduced  by  mounting  the  strip  over 
a  sheet  of  mica,  fiber  or  pasteboard  cut  to  size. 

It  will  be  observed  that  the  ungrounded, 
or  floating  end  of  the  coil  has  a  pressed  aluminum 
mount.  This  plate  is  large  enough  to  accom- 
modate a  coax  receptacle  if  one  of  the  four 
comers  is  sawed  off  flush  with  the  threads. 
It  was  feared  that  the  plate  would  be  twisted 
or  weakened  if  the  receptacle  were  mounted 
in  the  usual  manner,  so  a  7/16-inch  hole  was 
drilled  for  a  center,  and  the  fitting  mounted 
flush  against  this  support. 

To  the  coil  hub  at  this  end  is  soldered  a  short 
length  of  brass  rod  to  which  the  flexible  shafting 
can  be  connected  with  a  small  coupler.  This 
hub  looks  something  like  aluminum  or  pot  metal, 
but  it  is  actually  tinned  brass  and  solders  very 
easih'  if  a  heavy  soldering  iron  is  used. 

The  pick-up  transformer,  L1-L2,  for  the  reso- 
nance indicator  consists  of  one  turn  of  wire  on 
each  coil,  wound  on  a  ceramic  form  around  a 
powdered  iron  slug.  This  transformer  is  mounted 
at  the  end  of  the  bakelite  strip,  near  the  ground 
end  of  the  rotocoil,  with  a  machine  srrew  passed 
up  from  l^elow  the  base.  The  thermocouple 
can  be  mounted  directly  over  the  rider-spring 
strip,  between  the  two  springs.  The  mounting 
screws  will  have  to  be  slightly  longer  than  the 
ones  that  originally  mounted  the  thermocouple. 
One  turn  of  the  transformer  is  connected  between 
the  cold  end  of  the  rotocoil  and  ground.  The 
other  turn  is  connected  to  the  thermocouple 
terminals  marked  ''line."  Use  a  small  solder  lug 
on  the  wire  going  to  the  rotocoil. 

Matching 

In  matching  the  antenna  to  the  line,  several 
methods  might  be  used.  The  author  has  tried 


paralleUng  two  or  three  lengths  of  RG-8/U  to 
reduce  the  line  impedance.  \^Tiile  a  match  can 
be  obtained  in  this  manner,  difficulty  is  usually 
encountered  in  getting  sufficient  coupling  from 
the  transmitter  output  to  such  a  low-impedance 
line,  especiallj'  with  the  pi-section  output  circuits

SO  popular  in  manufactured  mobile  rigs.  Shunt 
feed  with  a  separate  matching  coil  at  the  base 
of  the  antenna  is  feasible,  but  the  most  simple 
and  satisfactory-  arrangement  tried  consists  of  a 
link  coil  coupled  to  the  ground  end  of  the  rotocoil. 
In  constructing  the  coupling  link  coil,  it  was 
found  that  3  turns  of  No.  14  could  be  fashioned 
so  that  when  one  end  is  grounded,  and  the  other 
end  fastened  to  a  J^-inch  stand-off  insulator,  no 
other  support  was  necessary-.  A  more  rugged 
and  professional-looking  job  might  be  done  bj* 
fastening  the  turns  together  at  several  points 
with  sealing  wax  or  poly  spacers.  The  link  is 
mounted  so  that  it  clears  the  rotocoil  b}-  about 
1/16  inch,  and  the  turns  are  spaced  about  the 
same  distance.  The  link  should  overlap  about 
5  turns  at  the  end  of  the  rotocoil.  It  will  be  neces- 
sary to  remove  the  solder  lug  and  lead  to  the 
thermocouple  transformer,  and  also  the  end 
mounting  of  the  rotocoil  in  order  to  slip  the  link 
coil  over  the  rotocoil.  A  short  length  of  stranded 
wire  is  soldered  to  the  lug  on  the  end  of  one  of 
the  rider  springs,  and  a  small  banana  plug 
is  soldered  to  the  other  end  to  connect  to  the 
antenna  mount. 

Installation 

The  unit  described  is  small  enough  that  it 
can  be  mounted  in  the  trunk,  close  to  the  base  of 
the  antenna,  without  interfering  with  the  use 
for  which  the  compartment  was  intended.  A 
ground  should  be  made  to  the  car  body  with  a 
short  length  of  copper  braid. 

The  flexible  shaft  and  timing  head  from  an 
SCR- 183  were  used  to  drive  the  coil.  This  was 
passed  forward  under  the  car  and  up  through  a 
hole  under  the  front  seat.  The  tuning  head  was 
mounted  on  the  hump  in  the  center  of  the  floor,

Little  Oskey"— A  Monitoring  Oscillator 

and  Keyer 

A  Simple  C.  W.  Break-in  Monitor  and  Code-Practice 

Oscillator 

BY  E.  LAIRD  CAMPBELL,  WICUT 


•  This  is  a  versatile  uuxiliary  uiiil  lliat 
■vvill  he  vcleonied  to  many  an  amatein- 
shack.  Without  modifying  a  receiver  or 
cathode-keyed  transmitter  in  any  >vay, 
and  without  the  need  for  extra  r.f.  pick- 
up, il  hlaiiks  ihe  receiver  and  injects  a 
sidetone  in  the  headphones  when  the 
key  is  down.  It  can  also  be  used  as  a  code- 
practice  oscillator,  on  those  occasions 
when  you  can't  fiml  anyone  to  QSO. 


SEVERAL  different  methods  of  c.w.  monitoring 
have  been  tried  at  WlCUT.  The  first,  and 
•■ —  most  simple,  involved  lowering  the  gain 
control  of  the  receiver  to  a  comfortable  level 
while  transmitting.  However,  even  with  the  gain 
turned  down  it  was  difficult  to  reach  a  pleasant 
listening  point,  and  constant  adjustment  was 
required.  If  the  station  being  worked  happened 
to  be  off  the  transmitting  frequency,  it  was  im- 
possible to  monitor  without  retuning  the  receiver 
to  the  transmitted  signal. 

The  second  method  for  c.w.  monitoring  made 
use  of  a  crystal  diode  to  rectify  r.f.  from  the 
transmitter.  The  rectified  voltage  keyed  a  neon 
bulb  audio  oscillator  and  produced  a  sidetone. 
This  system  proved  unsatisfactory  because  severe 
TVI  was  produced  by  harmonic  generation  in  the 
crystal  diode.'  Since  the  r.f.  for  the  unit  was 
obtained  from  a  pick-up  wire  near  the  final  am- 
plifier there  was  the  danger  of  high  voltage,  and 
when  changing  bands  it  was  necessary  to  alter 
the  position  of  the  pick-up  wire  to  obtain  suffi- 
cient r.f.  to  operate  the  unit.  Since  none  of  the 
above  monitoring  sj'stems  proved  satisfactory,  it 
was  decided  to  construct  a  break-in  monitor 
which  basicall}'  had  two  jobs  to  perform.  When 

'"Harmonic  Radiation  from  External  Nonlinear  Sys- 
tems," QST,  January,  1953. 


the  key  was  down  the  receiver  output  would  be 
completely  squelched  and  a  sidetone  would  ap- 
pear in  the  headphones,  and  when  the  kej'  was  up 
receiver  output  would  he  fed  through  to  the 
headphones.  Provisions  must  also  be  made  for: 

1)  No  adjustment  when  changing  frequency' 
or  bands. 

2)  Installation  in  station  without  revision  of 
transmitter  or  receiver. 

3)  A  sidetone  that  is  keyed  exactly  as  the 
transmitted  signal. 

4)  Keying  the  transmitter  and  sidetone  simul- 
taneously. 

5)  Mixing  the  outputs  of  the  receiver  and 
sidetone  oscillator. 

6)  Electronic  switching  from  sidetone  to  re- 
ceiver output. 

7)  Switching  the  monitor  out  for  the  purpose 
of  zero-beating  another  signal. 

The  monitor  described  here  can  perform  all 
of  the  above  jobs.  Since  the  unit  needs  no  external 
excitation,  it  can  also  be  used  as  a  code-practice 
oscillator. 

Circuit  and  Construction 

No  special  precautions  are  necessary  in  laying 
out  the  unit.  In  fact,  the  monitor  may  be  built 
in  a  cabinet  and  placed  alongside  of  the  receiver. 
When  wiring  the  unit,  it  is  a  good  idea  to  keep 
the  leads  carrying  a.c.  away  fi'om  the  amphfier 
input  to  prevent  hum.  Care  should  also  be  taken 
when  soldering  the  crystal  diodes.  Holding  the 
diode  leads  with  a  pair  of  long-nose  pliers  while 
soldering  is  good  insurance  against  ruining  a 
crystal.  Terminal  strips  can  be  used  conveniently 
for  mounting  parts  such  as  the  selenium  rectifier 
and  to  serve  as  tie  points  for  resistors,  capacitors, 
etc. 

Two  small  6-volt  filament  transformers  con- 
nected "back  to  back"  are  used  for  obtaining 


C.w.  monitor  and  code-practice  oscillator.

the  necessary  operating  voltages.  A  novel  voltage 
tripler  composed  of  one-half  of  the  12AU7  and 
two  crystal  diodes  supplies  the  voltages  for  re- 
ceiver squelching  and  the  audio  oscillator.  This 
voltage  is  controlled  by  the  transmitting  key  and 
is  turned  on  when  the  key  is  closed.  At  this  in- 
stant (when  the  key  is  closed)  the  sidetone  is 
produced  and  the  receiver  is  squelched  by  placing 
the  negative  voltage  on  the  grid  of  the  input  am- 
plifier tube.  When  the  key  is  opened  the  received 
signal  is  amplified  and  heard  in  the  'phone.';,  while 
the  sidetone  is  off. 

The  frequency  of  the  sidetone  audio  oscillalor 
can  be  adjusted  by  changing  the  grid  capacitoi', 
Ci.  If  the  audio  oscillator  fails  to  oscillate,  the 
primary  leads  of  the  interstage  transformer 
should  be  reversed. 


High  voltage  is  obtained  from  the  115-volt 
side  of  transformer  7'i.  This  is  followed  bj'  a 
selenium  rectifier  and  RC  filter  which  provides 
enough  voltage  for  good  amplification  in  the 
amplifier-mixer  stage. 

Operation 

It  is  a  very  simple  matter  to  insert  the  monitor 
into  an  existing  station.  The  cable  from  the  unit 
is  plugged  into  the  keyed  circuit  and  the  receiver 
output  and  head-phones  are  plugged  into  the 
unit.  Switch  .S'l  is  a  s.p.s.t.  switch  on  the  volume 
control  and  is  used  to  tiu'n  the  unit  off  and  on. 
If  for  some  reason  it  is  desired  to  operate  tem- 
porarilj'  without  the  unit  (such  as  when  zero- 
beating)  the  toggle  switch,  So,  may  be  opened  and

More  Power  with  the  AT-1 

Simple  Modifications  for  Greater  Output 
BY  LEWIS  G.  McCOY,  WIICP 


•  By  a  few  simple  modifications,  the 
power  output  of  the  Heathkit  AT-1  can 
be  raised  tw«>  to  three  times.  Any  Novice 
who  has  huilt  the  rig  and  used  it  h>ng 
enough  to  become  familiar  with  its  op- 
eration should  be  ready  for  the  slightly 
more  complicated  circuit.  This  article 
gives  step-by-step  directions. 


LISTENING  to  the  Novice  bands  for  a  short  time 
will  quickly  convince  anyone  the  Heathkit 
-*  AT-1  transmitter  is  a  very  popular  item.  As  it 
stands,  the  rig  will  handle  approximately  30  watts 
input  on  all  amateur  bands,  80  through  10  meters. 
Its  amplifier  works  straight  through  on  80,  but 


having  been  designed  for  loads  much  higher  than 
100  milliamperes,  will  not  deliver  much  more  than 
35  watts.  The  plate  voltage  drops  as  higher  cur- 
rent is  drawn  and  one  runs  into  the  law  of 
diminishing  returns. 

In  order  to  use  the  second  stage  as  a  straight- 
through  amplifier  it  is  necessary  not  only  to  install 
a  neutralizing  circuit  but  also  to  change  the  os- 
cillator coil  and  switching  circuit  to  permit  tuning 
the  amplifier  grid  and  plate  circuits  to  the  same 
frequency.  This  should  be  done  on  all  bands  with 
the  exception  of  10  meters,  where  the  change  is 
not  worth  while  because  the  oscillator  cannot 
deliver  sufficient  grid  drive  on  that  band  from  a 
7-Mc.  crystal.  If  a  6BQ6  is  to  be  substituted  for 
the  6L6  —  a  change  that  is  recommended,  and 


6B06

modifications  for  the  AT-1. 
The  changes  are  shown  by  the 
heavy  lines. 


20ppF 


on  all  other  bands  it  acts  as  a  frequency  doubler, 
presumably  to  avoid  the  necessity  for  neutralizing 
the  6L6.  Although  this  results  in  a  simpler  cir- 
cuit, it  also  means  that  the  power  output  is  con- 
siderably less  than  could  be  obtained  from  the 
same  6L6  as  a  straight-through  amplifier. 

To  operate  the  amplifier  straight  through,  the 
6L6  (and  practically  any  tube  that  might  be  sub- 
stituted for  it)  must  be  neutralized  to  prevent 
self -oscillation.  Neutralizing  is  neither  difficult 
nor  expensive,  and  the  additional  power  output 
is  certainly  worth  the  effort. 

Just  how  much  the  power  output  can  be  in- 
creased by  such  a  change  is  shown  by  Table  I, 
w^hich  gives  the  results  of  measurements  made  on 
a  modified  AT-1  vs.  the  unmodified  unit.  The 
table  also  includes  data  on  a  0BQ6  which  was 
substitutc^d  for  the  6L6,  this  tube  having  l)een 
tried  because  its  characteristics  indicated  that  it 
should  be  a  better  p(;rformer  than  the  (iLO.  A 
6146  was  also  tried  in  the  hope  that  its  ability  to 
draw  larg(!  piat(;  current  with  re^lativcly  low  plate 
voltage  would  result  in  greater  output  but,  un- 
fortunately, the  power  supply  in  the  AT-1,  not 


is  included  in  the  instructions  below  —  the  am- 
plifier socket  also  must  be  changed. 

Other  Modifications 

In  the  original  version  of  the  AT-1,  the  output 
links  are  fixed,  with  no  means  provided  for  ad- 
justing the  coupling.  According  to  the  instruction 
manual,  the  links  are  designed  to  work  into  a 
50-ohm  load. 

With  certain  types  of  antennas  and  antenna 
couplers,  a  fixed  link  may  be  OK  for  the  job,  but 
in  many  cases,  it  is  well-nigh  impossible  to  load 
the  output  stage  to  the  normal  input.  A  variable 
coupling  circuit  is  therefore  a  very  much  worth- 
while addition,  and  since  it  requires  little  more 
than  adding  an  inexpensive  variable  capacitor, 
it  is  included  in  the  modifications  described  below. 

Another  change  that  can  easily  be  made  con- 
sists of  adding  a  resistor  between  the  oscillator 
screen  and  chassis  ground  to  help  stabilize  the 
voltage  on  the  oscillator  screen.  This  results  in 
better  keying  characteristics. 

The  modifications  described  Ix^low  are  ar- 
ranged in  a  series  of  steps,  each  numbered.  The

QST  for 


component  designations  referred  to  are  the  same 
as  those  given  in  the  original  Heathkit  instruc- 
tions. The  circuit  diagram,  Fig.  1,  is  the  modified 
circuit  showing  only  the  information  necessary 
for  the  changes.  A  list  of  material  needed  for  the 
modifications  is  given  elsewhere  in  the  article. 

Oscillator  Modifications 

1)  Unsolder  the  leads  from  SBl,  2,  3,  and  4. 

2)  Unsolder  the  lead  from  XCl  to  COl  and  also  the  lead 
to  C02A.  Unsolder  the  leads  from  XCl,  2,  3,  and  4  and  clean 
the  solder  from  the  terminals. 

3)  Remove  CO  from  the  panel. 

Note:  In  some  of  the  AT-1  units  the  oscillator  capacitor 
is  insulated  from  the  panel  while  in  other  models  the  rotor 
shaft  of  the  capacitor  is  mounted  directly  on  the  panel.  If 
your  unit  is  the  type  with  the  insulated  mounting,  you  can 
omit  Step  4  and  the  use  of  insulating  washers  described 
in  Step  7.  (Check  parts  list  for  correct  type  of  capacitor 
needed.)  . 

4)  Enlarge  the  panel  hole  for  capacitor  GO  to  >t-inch 

diameter.  . 

5)  Drill  a  J/^-inch  diameter  hole  in  the  chaasis  top  one 
inch  in  from  the  panel  and  one  inch  to  the  left  of  the  large 
opening  in  the  chassis. 

6)  Mount  a  one-lug  terminal  strip  at  this  new  hole. 

7)  Mount  the  new  IOO-mmI-  variable  in  the  position  for- 
merly occupied  by  CO  using  an  insulating  washer  on  each 
side  of  the  panel.  . 

8)  Unsolder  the  end  of  the  osciUator  coil  winding  from 

terminal  No.  1.  ,.,,..    ^u    c    * 

9)  Unwind  the  top  turns  from  the  coil  down  to  the  hrst 
tap  point  but  do  not  remove  or  cut  the  wire;  then  drill  or 
punch  a  small  hole  in  the  coil  form  approximately  M  mch 
below  terminal  No.  2.  .     ,   t.t      o       j 

10)  Unsolder  the  2-wire  tap  from  terminal  No.  2  and 
solder  the  two  wires  to  terminal  No.  1. 

11)  Wind  three  turns  back  on  the  form,  and  at  the  point 
where  the  third  turn  is  opposite  the  new  hole  carefuUy 
scrape  the  enamel  from  the  wire.  ,     ,    . 

12)  Using  a  3-inch  piece  of  No.  18  tinned  wire,  feed  the 
end  of  the  wire  down  through  the  top  of  the  coil  form  and 
out  the  new  hole.  Solder  the  end  of  the  wire  to  the  point 
where  the  enamel  was  removed  from  the  third  turn. 

13)  Draw  the  other  end  of  the  wire  through  terminal  No. 
2  and  solder  to  the  terminal,  trimming  off  any  excess  length. 

14)  Wind  the  remaining  wire  from  the  coil  back  on  the 
form  and  bring  the  end  through  the  hole  immediately  below 
terminal  No.  3.  then  dress  the  end  of  the  wire  over  to  and 
through  the  hole  opposite  terminal  No.  2.  This  point  will

Maximum  plate  current  for  the  6BQ6  is  approximately  90  ma. 
With  a  plate  voltage  of  approximately  400  volts,  this  gives  an 
input  of  35  watts.  The  screen  current  with  this  tube  is  very  low

combined  plate  and  screen  current)  is  very  nearly  the  same  as  the 
plate  current  alone.

modifications. 

15)  Mount  the  coil  back  in  place. 

16)  In  the  original  instructions.  Pictorial  1  shows  a  lead 
connected  from  SB3  to  the  tinned  wire  between  TB2  and 
TCl.  Unsolder  and  remove  this  lead  (not  the  lead  between 
TB2  and  TCI). 

17)  Cut  an  8-inch  length  of  No.  18  tinned  wire  and  solder 
one  end  to  the  same  point  on  the  TB2-TC1  lead  as  the  short 
piece  formerly  occupied. 

18)  Bring  the  wire  up  through  the  large  opening  in  the 
chassis  and  bend  it  toward  the  oscillator  capacitor.  The  wire 
should  clear  the  top  of  the  chassis  by  approximately  IJ^ 
inches.  Dress  the  lead  over  to  the  stator  terminal  of  the 
oscillator  capacitor.  Bend  the  wire  at  this  point  so  that  the 
end  dresses  up  to  XC5.  Solder  the  wire  at  the  stator  terminal 
and  to  the  end  of  the  coil  at  XCo. 

19)  Feed  the  end  of  a  9-inch  length  of  tinned  wire  through 
XC4  over  to  SB4  and  solder  the  end  to  SB4.  Draw  the  wire 
tight  and  solder  at  XC4.  Feed  the  free  end  of  the  wre

through  the  insulated  lug  on  the  one-lug  terminal  strip 
mounted  in  Step  6.  This  lug  is  designated  TP2.  Draw  the 
wire  through  TP2  and  bring  the  end  up  to  the  rotor  side  of 
tlie  oscillator  capacitor.  Slip  a  piece  of  spaghetti  insulation 
over  the  wire  and  make  it  long  enough  to  cover  the  wire 
between  the  rotor  terminal  and  TP2.  Solder  the  connection 
at  the  rotor  terminal  but  not  at  TP2.  The  length  of  the  wire 
between  XC4  and  TP2  should  be  dressed  so  that  it  does  not 
touch  nearby  objects. 

20)  Connect  one  lead  of  a  470-;i/if.  mica  capacitor  to  TP2 
and  solder  the  other  lead  to  chassis  ground.  The  ground 
connection  can  he  made  at  the  screw  which  liolds  the  TP2 
terminal  strip  to  the  chassis. 

21)  Using  short  lengths  of  No.  18  tinned  wire,  connect 
one  lead  between  SB3  and  XC3,  one  lead  from  SB2  to  XCl, 
and  one  lead  between  SBl  and  XC2.  Solder  all  connections 
and  be  sure  that  no  lead  touches  another.  This  completes 
tlie  oscillator  modifications. 

Amplifier  Modifications 

22)  Remove  the  r.f.  choke  from  between  TC3  and  Pin  3 
of  the  6L6  socket.  Also  unsolder  the  end  of  the  lOO-M^f- 
capacitor  from  Pin  3. 

23)  Drill  a  J-g-inch  hole  in  the  chassis  top  }4  inch  from  the 
side  and  opposite  the  }^-inch  hole  near  the  tube  socket. 

24)  Mount  a  three-lug  terminal  strip  at  this  new  hole. 
The  lug  closest  to  the  panel  is  designated  TPAl,  the  middle 
lug  TPA2,  and  the  rear  lug  TPA3. 

25)  Unsolder  the  47K  resistor  from  B5  and  TC2. 

26)  Unsolder  the  0.001  capacitor  from  B8  and  cliassis 
ground.  Also  remove  the  lead  from  B8  to  Jl.  Clean  the  solder 
from  B8. 

27)  Cut  the  bare  wire  lead  between  Bl  and  B2  and  clean 
the  solder  from  Bl.  B2  is  left  connected  to  chassis  ground. 

28)  Solder  one  end  of  a  22K  J^-watt  resistor  to  TC2  and 
connect  the  other  end  to  Bl.  Solder  one  end  of  a  2.5-mh.  r.f. 
choke  to  Bl  and  solder  the  other  end  to  B5. 

29)  Solder  one  end  of  a  2.5-mh.  r.f.  choke  to  Jl  and  con- 
nect the  other  end  to  B8.  Solder  one  end  of  a  0.01  disk 
ceramic  capacitor  to  B8  and  solder  the  other  lead  to  chassis 
ground. 

30)  Solder  one  end  of  a  0.01  disk  ceramic  capacitor  to 


chassis  ground  and  connect  the  other  lead  to  TC3.  Solder 
one  end  of  a  four-inch  length  of  insulated  wire  to  TC3.  Feed 
the  other  end  up  through  the  J^-inch  liole  near  the  tubt^ 
.socket  and  connect  it  to  TPAl. 

31)  Solder  one  end  of  the  1.1-mh.  r.f.  choke  to  TP.\1  and 
connect  the  other  end  to  TPA2.  Connect  the  free  end  of  the 
100-MAif.  mica  capacitor  that  is  soldered  to  CA2A  to  TPA2. 

32)  Solder  one  end  of  a  13-inch  length  of  No.  24  enameled 
wire  to  one  lead  of  a  lOO-ohm  1-watt  carbon  resistor.  Make 
the  connection  close  to  the  body  of  the  resistor.  Be  sure  to 
scrape  the  enamel  from  the  end  of  the  wire  before  soldering. 

33)  Wind  14  close-spaced  turns  of  the  enameled  wire  on 
the  body  of  the  resistor  and  solder  the  end  of  the  wire  to 
other  resistor  lead.  Cut  one  resistor  lead  to  M  inch  long  and 
the  other  to  }^  inch. 

34)  Solder  the  J^-inch  resistor  lead  to  the  ceramic  plate 
cap  for  the  6BQ6.  Solder  the  other  lead  of  the  resistor  to 
the  end  of  a  31'^-inch  length  of  insulated  wire  (see  photo- 
graph). Connect  the  other  end  of  the  35^-inch  length  of  wire 
to  TPA2. 

35)  Cut  a  piece  of  tin  %  inch  wide  by  1  '/g  inches  long  from 
a  tin  can.  This  will  serve  as  a  mounting  plate  for  the  20M11 
neutralizing  capacitor.  See  Fig.  2  for  details  of  this  plate. 

36)  Mount  the  neutralizing  capacitor  on  the  plate  using 
the  shaft  nut  to  hold  the  capacitor  to  the  plate. 

37)  Cut  a  piece  of  No.  18  tinned  wire  8^4  inches  long  and 
also  a  piece  of  spaghetti  7V^  inches  long.  Slip  the  spaghetti 
on  the  length  of  tinned  wire. 

38)  Solder  one  end  of  the  tinned  wire  to  TPl,  which  is 
near  the  oscillator  capacitor.  Dress  the  wire  above  the  chassis 
top  and  feed  the  end  through  TPA3  so  that  approximately 
yi  inch  of  wire  extends  through  TPA3. 

39)  Mount  the  neutralizing  capacitor  plate  against  TPA3 
by  feeding  the  end  of  the  tinned  wire  lead  through  the  small 
hole  in  the  plate  and  then  bending  the  lead  back  around 
TPA3.  Heat  the  connection  and  flow  solder  around  the 
.joint  to  insure  a  good  connection. 

40)  Take  a  short  piece  of  No.  18  tinned  wire  and  solder 
one  end  to  the  stator  section  of  the  neiitralizing  capacitor. 
Connect  the  other  end  to  TPA2.  This  completes  the  ampli- 
fier modifications. 


The  AT-1  shown  here  was  the 
model  that  had  the  rotor  of  the 
oscillator  capacitor  grounded  to  the 
panel.  The  rotor  is  insulated  by 
enlarging  the  panel  hole  and  using 
insulated  washers  at  the  rotor 
mounting.  Just  above  the  oscillator 
tube  is  the  lead  from  the  stator  of 
the  oscillator  capacitor  to  the  new 
terminal  XCS  on  the  oscillator  coil. 


QST  for 


Output  Link  Changes 

The  variable  capacitor,  C3  in  Fig.  1,  can  be  one 
of  the  inexpensive  broadcast  replacement  types. 

The  maximum  capacitance  must  be  more  than 
:500  fifxi.  Because  of  manufacturers'  variations  in 
construction,  the  method  of  installation  may 
vary  in  each  case.  In  the  unit  described  here,  a 
^2-iiich  hole  was  drilled  in  the  panel  1}4:  inches 
from  the  top  of  panel  and  directlj-  over  the 
amplifier  capacitor  CA.  A  small  aluminum 
bracket  was  made  to  hold  the  capacitor  in  place. 
The  frame  of  the  capacitor  was  mounted  on  the 
bracket  with  two  small  screws  and  the  bracket 
mounted  to  the  panel.  The  important  thing  to 
remember  when  mounting  the  capacitor  is  that 
the  frame  or  rotor  is  grounded  to  the  chassis  and 
the  stator  is  insulated  from  the  chassis. 

After  the  capacitor  is  mounted  in  place,  the 
amplifier  coil  assemblies  —  80C,  40C,  20C.  and 
IOC  —  must  be  removed  from  their  holders.  The 
easiest  method  of  removing  them  is  to  unsolder 
the  leads  on  the  80-meter  coil  at  Terminals  2  and 
4  and  then  1  and  3,  working  down  in  this  manner 
until  all  coils  are  removed.  The  coils  are  then 
ready  for  modification. 

41)  Unsolder  the  link  ends  from  Terininala  3  and  4  on 
IOC  and  remove  the  link.

42)  Punch  a  small  hole  in  the  coil  form  between  the  sec- 
ond and  third  turns  of  the  amplifier  coil  counting  from  the 
link  end  and  on  the  same  side  of  the  coil  form  as  terminal 
No.  4. 

43)  Using  No.  24  enameled  wire,  insert  one  end  of  the 
wire  through  the  new  hole,  bring  the  end  up  to  terminal  No. 
4,  and  solder.  Be  sure  to  scrape  the  enamel  from  the  end  of 
the  wire  before  soldering. 

44)  Wind  2J2  turns  of  the  No.  24  enameled  wire  on  the 
coil  form,  the  first  IJ^  turns  being  interwound  with  the 
amplifier  coil  in  the  same  direction.  Insert  the  end  of  the 
wire  into  the  hole  just  at  the  end  of  the  amplifier  coil,  feed 
the  end  up  to  terminal  No.  3,  and  solder.  Remount  the 
coil  in  place  but  do  not  connect  leads  to  terminals  1  and  3. 
Solder  the  leads  from  the  switch  to  their  original  connections 
on  terminals  2  and  4. 

45)  Unsolder  and  remove  the  link  from  terminals  3  and  4 
of  20c.  Wind  on  7}i  turns  of  No.  24  enameled  wire  using 
the  same  holes  for  the  new  link.  Remount  the  coil,  making 
connections  to  the  switch  leads  but  not  terminals  1  and  3. 

46)  Using  the  same  procedure  outlined  above,  wind  a 
new  link  on  40C  consisting  of  12}4  turns  of  No.  24  enameled 
wire.  Mount  the  coil  back  in  place.

an  80-meter  ciystal  into  the  crj-stal  socket,  and

The  GPR-90  Communications  Receiver 


BE  it  automobiles  or  communications  receivers, 
interest  always  runs  high  when  a  new  one  is 
announced.  Each  j^ear  the  new  models  are 
carefully  scanned  to  see  if,  at  last,  "they"  have 
built  our  dream  car  or  dream  receiver.  But, 
dreams  being  what  they  are  and,  we  hear,  so 
widely  diversified,  there  never  will  be  a  dream  job 
that  will  match  up  with  everyone's  reveries. 
To  be  practical  about  it,  one  should  look  for 
the  refinements  and  new  ideas  that  add  up  to 
the  evolution  of  this  and  next  year's  models. 

The  GPR-90  will  serve  as  a  good  example. 
It  is  a  two-dial  receiver  and  it  has  double  con- 


The  manufacturers  of  the  receiver  are  new  to 
the  amateur  field  but  not  to  the  receiver-building 
game,  since  they  have  been  building  radio  gear 
for  the  government  and  military  for  years.  This 
experience  is  reflected  in  the  GPR-90.  There  is  a 
clean  and  refreshing  look  about  the  receiver  and 
a  quality  about  the  finishes  and  wiring  that  one 
recognizes  as  the  result  of  having  to  satisfy 
government  inspectors  and  quality-control  de- 
partments. The  receiver  looks  as  though  it  might 
stand  some  rough  handling. 

Electrically,  you  can  get  a  fair  idea  in  a  hurry 
from  the  block  diagram  in  Fig.   1.  Hey!  How

The  bottom  cover  over  the

plified  circuit  is  shown  in  Fig.  2. 
There  will  undoubtedly  be  some 
customers  who  will  hook  a  random- 
length  antenna  on  the  receiver 
and  not  get  as  good  signal  transfer  as  they 
would  with  a  proper  antenna  and  feed  line, 
but  this  is  true  with  all  short-wave  receivers. 
The  GPR-90  at  least  gives  the  knowing  op- 
erator a  choice  of  two  popular  impedance  lev- 
els. On  the  lower-frequency  bands  the  antenna 
couples  to  Li  through  a  primary  winding,  and 
under  these  conditions  the  ANT  TRIM  panel 
control  (a  small  variable  across  C2)  is  truly 
an  antenna  trimmer.  When  the  6AB4  is  in 
the  circuit,  the  ANT  TRIM  becomes  a  trim- 
mer control  to  bring  the  r.f.  stages  into  align- 
ment.  Since   the   value   of   i?i   is   increased  on 


Fig.  2  —  Simplified  schematic 
diagram  of  the  grounded-grid  r.f. 
stage  used  above  3.2  Mc.  Ri,  Ci 
and  Li  are  switched  for  the  various 
ranges  and  have  different  values 
on  the  various  bands.  Ti  is  the 
same  on  all  bands. 


the   higher-frequency   ranges,    the   gain   of   the 
grounded-grid  stage  increases  in  these  ranges. 

Getting  back  to  the  over-all  picture,  the 
grounded-grid  stage  is  followed  by  a  more  usual 
r.f.  stage.  The  6AG5  oscillator  is  coupled  into 
the  cathode  circuit  of  the  6AU6  mixer.  In  the 
two  lowest-frequency  ranges  the  output  of  the 
6AU6  mixer  is  switched  into  the  6BA6  buffer 
i.f.  stage  at  455  kc,  but  on  the  higher-frequency 


ranges  it  is  switched  into  the  6BE6  converter 
stage.  The  grid  circuit  of  the  6BE6  has  three 
circuits  tuned  to  3.995  Mc,  and  its  oscillator 
circuit  is  self-controlled.  The  manufacturer  states 
that  no  appreciable  improvement  in  stability 
could  be  gained  by  using  crystal  control  at  this 
point.  With  the  6BE6  converter  active,  the 
6BA6  buffer  i.f.  is  not  used. 

The  crystal  filter  circuit  is  similar  to  that  used 
in  most  receivers  today,  and  has  provision  for 
five  degrees  of  selectivity.  The  SELECTIVITY 
switch  on  the  panel  is  marked  in  bandwidths  at 
the  —  3  db.  points,  and  these  range  from  200  to 


feAB4 


6CB6 


2000  cycles.  A  sixth  position  on  the  switch  cuts 
out  the  crystal  filter  and  gives  a  6-kc.  bandwidth 
at  —  3  db.  and  an  18-kc.  bandwidth  at  —  40  db. 
The  manufactiurer's  bandwidth  curves  show  the 
—  40  db.  bandwidth  in  the  sharpest  position  to 
be  5  kc. 

Following  the  crystal  filter  there  are  three  i.f. 
stages.  The  first  two  are  included  in  the  gain- 
control  circuits  (cathode  control  for  manual,  grid

control  for  a.v.c.)  and  the  last  stage  runs  at 
constant  gain.  The  b.f.o.  is  injected  at  the  grid 
of  the  last  i.f.  stage,  and  there  is  also  an  i.f.  take- 
off at  this  point  for  s.s.b.  adapters  and  other 
accessories.  The  diode  detector  and  automatic 
noise  Umiter  (series  diode)  are  conventional,  but 
the  use  of  variable  audio  selectivity  is  not.  This 
consists  of  a  paraUel-tuned  circuit  peaked  at 
around  1200  cycles.  A  variable  resistor  in  series 
with  the  inductance  allows  the  operator  to 
change  the  Q,  and  consequently  the  selectivitj' 
of  the  circuit,  from  a  sharp  position  that  will 
separate  the  mark  from  the  space  signal  of  a 
teletype  signal  to  a  broad  position  that  is  useful 
for  'phone  reception.  The  inductor  is  a  toroid. 

The  receiver  includes  most  of  the  auxiUary 
outlets  found  to  be  useful  in  present-day  re- 
ceivers: phono  input,  accessory  socket,  and  even 
a  utiUty  a.c.  outlet  and  a  power  plug  for  vibrator 
or  battery  operation. 

The  six  tuning  ranges  of  the  receiver  are  0.54 
to  1.4  Mc,  1.4  to  3.3,  3.2  to  5.6,  5.4  to  9.7,  9.4 
to  17.8  and  17.3  to  31.5  Mc.  The  band-set  dial 
has  an  auxiliary  scale  that  can  be  used  for  ac- 
curate logging  of  the  settings  necessary  for  ham- 
band  operation  or  anything  else,  and  for  wide- 
range  use  following  a  6-  or  2-meter  converter  it 
was  noted  that  it  requires  four  knob  rotations  to 
cover  14.0  to  17.8  Mc.  There  are  locks  for  both 
dials.  Dial  mechanisms  are  always  interesting,  we 
think  —  in  the  GPR-90  these  consist  of  rim  fric- 


tion drive  of  the  celluloid  scales,  from  which  a 
small  gear  drives  a  spring-loaded  gear  on  the 
capacitor  shaft.  There  are  heavy  flywheels  on  the 
knob  shafts  to  furnish  inertia  for  smooth  tuning. 

On  the  bandspread  side,  5M  turns  are  required 
to  cover  3.5  to  4.0  Mc,  3^  for  the  40-meter  band, 
4J^  for  the  20-meter  band,  2'^i  for  15,  and  3H 
for  10  meters. 

Mechanically,  there  are  a  few  things  in  the 
GPR-90  that  you  don't  normally  find  in  com- 
munications receivers.  One  of  the  photographs 
shows  the  tuning  capacitors  —  these  are  securely 
tied  at  two  points  to  the  heavy  front  subpanel 
and  at  no  other  point.  An  extension  at  the  rear 
of  each  capacitor  floats  in  a  rubber  grommet,  and 
consequently  it  is  difficult  for  any  chassis  defor- 
mation to  be  transmitted  to  the  capacitors.  We 
have  seen  receivers  with  the  tuning  capacitors 
bolted  to  the  chassis  that  were  very  sensitive  to 
chassis  deformation  —  apparently  the  GPR-90 
engineers  have  too.  Frequent  use  of  tie  points 
and  terminal  boards  underneath  the  chassis,  and 
tube  locks  on  the  5U4G  and  6V6,  reflect  the 
government-specification  work  mentioned  earlier. 
The  components  appear  to  be  high  quality:  A-B 
type  variable  resistors,  and  ceramic  insulation 
and  air  trimmers  throughout  the  oscillator  section 
are  examples.

The  Gonset  V.H.F.  Linear  Power  Amplifier 


UNTIL  the  advent  of  single  sideband,  the  linear 
amplifier  was  little  known  in  amateur  cir- 
cles. Among  v.h.f.  men,  particularly,  the 
linear  was  almost  unheard  of,  but  here  is  a  com- 
mercial product  that  seems  bound  to  change  all 
that. 

The  Gonset  V.H.F.  Linear  Power  Amplifier  is 
designed  as  a  matching  unit  for  the  popular 
Communicator,  and  it  is  available  for  either  50 


or  144  Mc.  When  driven  by  the  Communicator, 
or  any  amplitude-modulated  rig  of  3  to  6  watts 
output,  the  linear  amplifier  provides  a  power  step- 
up  of  about  10  db.,  and  it  requires  no  additional 
accessories  of  any  kind.  It  contains  its  own  send- 
receive  relay,  so  that  the  receiver  of  the  Commu- 
nicator can  be  used.  Only  two  cables  are  required; 
one  between  the  Communicator  output  and  the 
amplifier  input,  and  the  other  between  the  an- 
tenna relay  and  the  receiver. 
These  are  furnished  with  the 
unit. 


The  Gonset  V.H.F.  Lin 
ear  Power  Amplifier,  shown 
here  with  its  companion 
unit,  the  Communicator,  as 
a  driver,  is  availahle  for 
either  50  or  144  Mc. 


42 


QST  for 


The  Gonsct  v.h.f.  amplifier  uses  a  pair  of  8268,  aiitl 
has  its  own  built-in  high-voltage  and  bias  supplies. 
Power  output  is  about  50  watts,  on  voice,  when  drive 
is  supplied  by  the  Communicator  or  a  similar  modulated 
rig  of  3  to  6  watts  output. 

The  amplifier  uses  two  826s  in  push-pull. 
Plate  voltage,  between  1050  to  1100  under  nor- 
mal load,  is  supplied  by  a  pair  of  5U4GB  rec- 
tifiers in  series.  Grid  bias  is  obtained  from  a  se- 
lenium rectifier.  The  send-receive  relay  is  con- 
nected in  the  negative  high-voltage  lead,  and  is 
adjusted  to  close  when  the  plate  current  of  the 
826s  is  100  ma.  or  more.  In  addition  to  switching 
the  antenna,  the  relay  also  shorts  out  a  section  of 
bias  supply  bleeder,  decreasing  the  effective 
operating  bias  when  the  ampUfier  is  being  driven. 
Closing  of  the  relay  at  about  100  ma.  plate  cur- 
rent means  that   a   minimum  of  about   3   watts 


of   drive   is   required   to   operate   the   amplifier. 

A  meter  jack  is  provided  in  the  center  tap 
of  the  826  filaments,  but  a  meter  is  not  required 
for  normal  tuning  or  operation.  A  tuning  lamp  is 
coupled  to  the  transmitter  output,  and  the  user 
merely  tunes  the  various  controls  for  the  highest 
brilliance  in  the  lamp  that  will  allow  upward 
modulation.  This  \\411  be  about  40  to  50  watts 
output,  with  the  drive  that  is  obtainable  from  the 
Communicator.  If  the  amplifier  is  to  be  used  for 
c.w.  or  f.m.  service,  it  is  merely  adjusted  for 
maximum  tuning  lamp  brilliance  as  modulation 
capability  is  then  of  no  importance. 

The  operator  should  also  take  note  of  the 
plate  color  of  the  826s,  and  this  is  observed  read- 
ily through  a  panel  window.  A  tendency  to  run 
hotter  than  the  normal  cherry  red  is  an  indication 
of  excessive  grid  drive.  A  300-ma.  meter  should 
be  plugged  into  the  center-tap  jack,  and  the  drive 
adjusted  until  no  more  than  about  225  ma.  is  in- 
dicated, corresponding  to  a  driving  power  of 
about  6  watts. 

Safety  note:  As  soon  ar.  the  operating  switch 
is  turned  on,  plate  voltage  is  appUed  to  the 
826s.  This  makes  operation  of  the  unit  outside 
the  cabinet  extremely  dangerous,  as  the  tubes 
themselves  show  no  indication  of  plate  voltage 
until  drive  is  applied.  There  should  be  no  oc- 
casion for  operation  of  the  ampUfier  with  the 
cover  removed.  Neutralization,  the  only  adjust- 
ment that  is  likely  ever  to  be  required,  is  accom- 
pUshed  through  the  bottom  of  the  case,  and  no 
high-voltage  circuits  are  exposed  with  the  back 
cover  removed.  If  you  must  look  at  "the  works" 
be  sure  that  the  a.c.  cord  is  removed  from  the  out- 
let, and  then  short  the  plate  coil  to  ground  with 
an  insulated  screwdriver  before  touching  any  of 
the  circuits.

TUNING  WHIP  LOADING  COILS 

AN  electric  windshield-wiper  motor,  mounted 
-  adjacent  to  the  base  of  a  mobile  whip,  pro- 
vides a  convenient  and  inexpensive  means  of 
tuning  a  roller-type  base  loading  coil.  It  is  very 
easy  to  arrange  for  reverse  rotation  of  the  motor 
because  the  field  winding  is  brought  out  to  a 
switch.  Wiper  motors  can  usually  be  obtained 
from  an  auto  junk  yard  for  a  dollar  or  two.

MOBILE  ANTENNA  MOUNTS  FOR 
144  MC. 

THE  antenna  mounting  bracket  shown  in  Fig.  1 
is  made  from  a  piece  of  0.064-inch  aluminum 
strip.  It  permits  vertical  moimting  of  a  quarter- 
wave  144-Mc.  whip  and  can  be  easily  fastened  to 
the  rain  trough,  above  a  car  door,  by  self-tapping 
screws. 

The  %-inch  mounting  hole  at  the  top  of  the 
bracket  will  accommodate  the  base  of  a  Master 
Mobile  2-meter  whip.  On  the  other  hand,  the 
bracket  may  be  fitted  with  a  Type  83-lJ  coax

Type  83-1 SP  connector,  can  be  quickly  fastened 
to  the  assembl^^ 

Fig.  2  shows  a  more  complex  but  more  efficient 
antenna  mount.  The  base  for  the  assembly,  a 
rubber  suction  cup  such  as  is  used  with  car-top 
carriers,  is  fitted  with  a  brass  adapter  (home- 
made) that  mates  with  a  Type  83-lT  coax  "Tee" 
adapter.  The  suction  cup  and  the  brass  insert  are 
fastened  tog«!ther  with  a  flat-head  machine  screw. 
The  head  of  the  screw  is  covered  with  a  fiber 
washer  to  prevent  contact  between  the  screw  and 
the  inner  conductor  of  the  Tee  adapter.  If  the 


inner  conductor  of  the  Tee  is  drilled  out  at  the 
bottom  end,  it  will  not  be  necessarj^  to  use  the 
fiber  washer. 

R.f.  power  is  fed  to  the  center  tap  of  the  Tee 
adapter  via  a  length  of  RG-58/U  cable,  a  Type 


4"  of   RG-58/U  WITH

The  19-inch  whip,  equipped  with  a  83-lSP  con-

Both  of  the  installations  are  neat  in  appearance, 
can  be  easily  mounted  on  the  car,  and  permit 
rapid  removal  of  the  antenna.  When  mounting 
the  system  shown  in  Fig.  2,  it  is  advisable  to  applj' 
a  thin  film  of  glj-cerine  to  the  inside  of  the  cup 
before  ^he  latter  is  fastened  to  the  roof  of  the  car. 

Incidentally,  a  gain  in  signal  strength  is  evident 
when  changing  over  from  the  rain  trough  to  the 
roof-center  mounted  antenna.

OSCILLATOR  MODIFICATION  FOR 
THE  "GLOBE  SCOUT"  TRANSMITTER 

THE  6V6  oscillator  tube  in  the  W.R.L.  "Globe 
Scout"  transmitter  requires  more  drive  than 
some  of  the  small  VFO  units  will  deliver.  This 
condition  can  be  quickh'  remedied  bj'  changing 
the  oscillator  tube  to  a  6AG7,  as  suggested  to  me 
by  WlDJC.  The  oscillator  tube  socket  must  be 
rewired  to  accommodate  the  new  tube,  but  it  is 
not  necessary  to  alter  the  basic  circuit. 

After  the  modification,  the  transmitter  can 
be  driven  by  a  small  VFO  such  as  the  Heathkit 
VF-1,  and  will  work  as  well  with  crystal  control 
as  it  did  before.

of  plate  voltages  —  ratings  being  150  ma.  each

A  TRANSISTORIZED  OSCILLATOR 
FOR  3.5  MC. 

HAMS  have  found  man}-  appUcations 
for  junction  transistors,  even  though 
manj^  previous  types  have  been  limited 
to  audio  and  intermediate  frequencies. 
The  most  recent  transistor  is  Raytheon's 
tjTje  2N112  (formerly  known  as  CK760). 
It  has  a  cut-off  at  5  Mc.  and  easily  oscil- 
lates at  3.5  Mc.  and  above  with  only  a 
1.5-volt  source  of  power. 

The  schematic  in  Fig.  4  is  that  of  a 
simple  oscillator  useful  at  3.5  Mc.  and 
its  harmonics.  With  a  crjstal  inserted 
into  the  socket.  Ci  tunes  broadly  to  the 
desired  frequency.  For  VFO  output,  re- 
move the  cr\stal  and  insert  a  dummy 
crystal  holder  with  its  terminals  shorted. 
Then  Ci  tunes  the  band  with  sufficient 
overlap  at  each  end.  The  tone  is  T9  and 
remains  stead\'  as  a  rock  after  a  minute 
or  two  drift.

supply.  Ci  should  be  rated  at  1500  volts  or  more.  Si

transformer  ratings  are  discussed  in  the  text. 


it),  I  came  up  with  the  following  gimmick  which 
may  be  of  interest  to  some  rig  builders. 

Originally  I  planned  to  put  a  pair  of  807s  or 
equivalent  tubes  in  the  final,  and  so  provided  a 
600-volt  250-ma.  power  supply  for  them.  I  also 
planned  to  use  a  pair  of  the  same  tubes  as  modu- 
lators, and  provided  a  separate  600-volt  250-ma. 
power  supply  for  them.  After  both  power  sup- 
plies were  installed  on  the  chassis  and  working,  I 
considered  the  fact  that  half  of  my  available  d.c. 
power  was  unused  on  c.w.  A  little  thought  evolved 
the  circuit  showm  in  Fig.  3. 

Basically,  the  control  is  a  3-pole  3-position 
switch.  In  the  'phone  position  it  runs  the  r.f. 
section  from  one  600-volt  supply,  and  the  modu- 
lator from  the  other.  In  the  c.w.  position  it  re- 
moves plate  power  from  the  modulators  and 
shorts  out  the  secondary  of  the  modulation  trans- 
former. In  the  third  position,  called  hi-power  c.w., 
it  places  the  two  600-volt  supplies  in  series,  giving 


Fig.  4  ■ —  Circuit  diagram  of  the  transistorized  oscilla- 
tor. Li  is  the  plate  winding  of  a  broadcast-oscillator  coil 
(Meissner  14-1058  or  equivalent). 


This  circuit  may  be  used  as  a  signal  generator 
for  ham  frequencies,  calibration  purposes  or  as  an 
external  b.f .o.  for  a  short-wave  receiver  having  no 
beat  oscillator  of  its  own.  Simph^  tune  the  tran- 
sistor circuit  approximate!}'  to  that  of  a  c.w.  sig- 
nal. This  creates  a  beat  with  the  incoming  signal. 
No  need  to  alter  the  receiver. 

The  oscillator  uses  less  than  0.5  ma.  at  1.5  volts, 
but  it  can  be  driven  safely  with  up  to  6  volts.

ANOTHER  SOURCE  OF  COIL  FORMS 

Two  TYPES  of  vials,  used  by  druggists  for  pack- 
aging pills,  make  excellent  coil  forms  of  the 
inexpensive  variety.  Complete  with  plastic  caps 
that  may  be  used  as  mounting  feet,  the  vials

come  in  two  convenient  sizes.  One  has  a  diametei' 
of  slightly  less  than  Jg  inch  and  the  other  is  an 
even  1  }s  inches  in  diameter.  Both  types  provide  a 
wuiding  length  of  1 3  2  inches.  If  a  plug-in  assem- 
l)ly  is  required,  either  form  ma>-  be  mounted  on 
an  old  tube  base  or  an  octal  plug.  The  caps  can  be 
pierced  by  a  pin,  scribe  or  other  pointed  object. 
A  drill  held  by  a  pair  of  pliers  may  be  used  for 
drilling  holes  in  the  forms. 

The  vials  are  manufactured  by  Lermer  of 
Garwood,  X.  J.  My  local  drug  stoi-e  retails  them 
at  two  for  a  nickel.

RTTY  REGULATOR  CIRCUIT 

IN  the  process  of  building  an  RTTY  converter,  I 
ran  into  trouble  regulating  the  60  ma.  for  the 
printer  coils.  The  problem  was  solved  b}'  using 
the  circuit  shown  in  Fig.  5. 


TO    PRINTERO 


C0IL(60MA)O 


Fig.  5  —  Circuit  diagram  of  llic  1{  TI'V  regulator  cir- 
cuit. Ri  should  have  a  linear  taper. 

In  operation,  the  parallel  tjSNTGT  acts  as  a 
voltage  regulator  for  the  screen  of  the  (jLb,  hold- 
ing the  screen  voltage  to  verj^  close  Umits  regard- 
less of  screen  current.  Under  these  conditions,  the 
plate-current  v>s.  plate-voltage  curve  of  all  beam 
power  tubes  comes  into  effect,  thus  holding  the 
current  in  the  plate  circuit  to  the  value  selected 
by  adjustment  of  the  U.5-megohm  potentiometer. 
In  practice,  I  found  that  the  addition  to  the  cir- 
cuit of  two  more  printing  coils  (1500  ohms  each) 
plus  700  ohms  of  line  dropped  the  printer  current 
not  more  than  2  ma.  The  arrangement  helped  to 
straighten  out  the  inductive  lag  in  the  build-up 
of  the  60  ma.  It  almost  completely-  removes  the 
mark  bia.s  previously  present. 

The  circuit  works  directly  into  the  printer  coil 
without  using  the  polar  rela.\'.  I  did  this  because 
the  onl.\'  polar  rela>'  on  hand  was  Ijad  and  couldn't 
be  quieted  down.  However,  after  using  this  for 
kejing,  I  will  nevei'  use  another  polar  relay.  No 
filtering  whatever  is  necessar\-.  and  there  is  just 
that  much  less  equii)ment  to  give  tiouble.  The 
polar  relay  was  never  intended  to  be  used  for 
RTTY  or  short-haul  work  hi  the  first  place.  Its 
intended  use  is  on  long  lines  where  the  excessive 
capacity-  lesults  in  a  delay  in  the  mark  without  a 
corresponding  delay  in  space.  The  polar  normally' 
works  into  a  circuit  where  the  line  furnishes  25 
ma.  plus  for  mark  and  25  ma.  minus  foi-  space. 
Thus  any  delaj'  or  other  distortion  on  marU  will 


be  matched  by  a  corresponding  distortion  on 
space,  which  can  be  compensated  for  in  the  ad- 
justments in  the  relay.  All  this  is  unnecessar\'  for 
RTTY  or  short-haul  work. 

Notice  that  the  power  supply  used  with  Fig.  5 
is  connected  with  the  plus  side  grounded  (for 
safety  reasons)  and  that  it  also  furnishes  voltage 
for  the  d.c.  amplifier.

RE  THE  THREE-WAY  SWITCH  FOR  THE 
SIMPLEST  MODULATOR 

SOME  time  ago,  one  of  ni}-  students  installed  a 
circuit  similar  to  the  one  shown  on  page  86, 
QST  for  March,  1955.  In  doing  so,  the  original 
cathode-to-ground  lead,  a  short  length  of  stout 
wire,  was  replaced  by  a  pair  of  long  leads  running 
to  and  from  the  switch.  His  rig  was  thereby  ren- 
dered inoperative  because  of  instability.  The 
problem  was  solved  by  connecting  a  0.001-yuf.  disk 
ceramic  directly  between  the  cathode  terminal 
of  the  tube  socket  and  ground.  A  simple  point  to 
be  sure,  but  one  that  may  easily  be  overlooked 
Ijj'  inexperienced  amateurs.

CONELRAD  FOR  AMATEURS 

As  previously  reported  in  QS7'  (p.  9,  April, 
1953;  p.  46,  August,  1954)  the  Federal  Communi- 
eations  Commission  has  been  in  process  of  bring- 
ing the  amateur  radio  service  under  a  radio  se- 
curity system  called  "Conelrad"  (for  CONtrol 
of  ELectromagnetic  RADiation).  Its  purpose  is 
to  shut  down  amateur  radio  stations  —  except 
RACES  stations  —  in  the  event  of  enemy  attack, 
so  that  no  navigational  aid  may  be  available  to 
enemy  aircraft.  The  system  has  alread,y  been 
j)Ut  into  effect  in  many  other  radio  services.  On 
August  31st  FCC  issued  proposed  rule-making 
to  add  the  amateur  service,  the  text  of  which 
appears  below.  Any  comment  must  be  filed  by 
October  3rd. 

As  an  inspection  of  the  text  will  show,  amateurs 
will  be  required  to  have  some  means  of  knowing 
whether  a  radio  alert  is  in  process.  Since  a  princi- 
pal means  of  dissemination  of  the  alert  is  by 
standard  broadcast  stations  (as  well  as  FM  and 
TV),  monitoring  a  near-by  b.c.  station  either 
aurally  or  with  a  simple  visual  indicator  will  un- 
doubtedly be  the  simplest  solution.  QST  will 
carry  information  on  appropriate  methods  in 
future  issues;  see  also  p.  17,  September,  1953.

APPENDIX 

It  is  projjosed  to  amend  Part  12  of  the  C'oiiimi.ssion'.s 
Rules  by  adding  the  following  new  Sections: 

CONELRAD 

12.190  Scope  and  Objeclirc  of  CONELRAD.  CONtrol  of 
ELectromagnetic  R.^Diation  applies  to  all  radio  stations 
in  the  .Amateur  Radio  Service  and  is  for  the  purpose  of 
providing  for  the  alerting  and  operation  of  radio  stations 
in  this  service  during  periods  of  air  attack  or  imminent 
ttireat  thereof.  The  objective  is  to  minimize  the  navigational 
aid  that  may  be  obtained  by  an  enemy  from  the  electro- 
magnetic radiations  emanating  from  radio  stations  in  the 
.\mateiir  Radio  Service  while  simultaneously  providing  for 
a  continued  service  under  controlled  conditions  when  such 
operation  is  essential  to  the  pubhc  welfare. 

12. 191  The  CONELRA  D  RADIO  A  LERT  is  the  term  ap- 
plied to  the  Military  Warning  that  an  air  attack  is  probable 
or  imminent  and  which  automatically  orders  the  immediate 
implementation  of  CONELR.^D  procedures  for  all  radio 
stations.  The  CONELRAD  RADIO  ALERT  is  distinct 
from  the  military  or  Civil  .Air  Defense  Warnings  YELLOW 
or  RED,  but  may  be  coincidental  with  such  warnings. 

12.192  Reception  of  RADIO  ALERT,  (a)  The  licensee  of 
a  station  in  the  Amateur  Radio  Service  is  required  to  provide 
a  means  for  reception  of  the  CONELRAD  RADIO  ALERT 
or  a  means  for  the  determination  that  such  ALERT  is  in 
force. 

(b)  All  operators  of  stations  in  the  .\niateur  Radio 
Service  will  be  responsible  for  the  reception  of  the  CONEL- 
RAD RADIO  ALERT  or  indication  that  such  ALERT  is  in 
force  by: 

(1)  reception  of  a  CONELRAD  RADIO  ALERT 
MESS.\CiE  which  will  be  broadcast  by  each 
standard.  FM  and  TV  broadcast  station  on  its 
regular  assigned  frequency  before  they  leave  the 
air;  or 

(2)  reception  of  standard  broadcast  stations  operat- 
ing under  CONELRAD  requirements  during 
the  period  of  the  .\LERT  on  640  or  1240  kc;  or 

(3)  determining  that  an  .\LERT  is  in  force  by  lack 
of  normal  broadcast  station  operation  (observa- 
tions made  before  amateur  station  operation  is 
begun  and  at  least  once  every  ten  minutes  dur- 
ing operation  thereafter  will  be  considered  as 
sufficient  for  compliance  with  this  Section) ;  or 

(4)  other  means  if  so  authorized  by  the  Federal 
Communications  Commission. 

12.193  Operation  Dwing  an  ALERT.  During  a  CONEL- 
RAD R.\DIO  .\LERT  the  operation  of  all  amateur  radio 
stations,  excejit  stations  in  the  Radio  Amateur  Civil  Emer- 
gency Service  (R.ACES)  and  stations  specifically  author- 
ized otherwise,  will  be  immediately  discontinued  until  the 
RADIO  ALL  CLEAR  is  issued.  Stations  in  the  RACES 
and  such  others  as  are  specifically  authorized  to  operate 
during  the  .\LERT  will  conduct  operation  under  the  fol- 
lowing restrictions. 

(a)  No  transmission  shall  be  made  unless  it  is  of  ex- 
treme emergency  affecting  the  national  safety 
or  the  safety  of  life  and  property. 

(b)  Transmissions  shaU  be  as  short  as  possible. 

(c)  No  station  identification  shall  be  given,  either 
by  transmission  of  call  letters  or  by  announce-

AMATEUR'S  CODE 

P.  O.  Box  26 
Cliauvin,  La. 
Editor,  QST: 

Paul  M.  Segal's  Amateur's  Code  is  worth-while.  Here's 
another  way  of  putting  it: 
Amiable 
Moderate 
Alert 

True  to  ARRL  (high  fidelity) 
Energetic 

Useful  for  self,  church,  community,  country 
Refined  —  pure  in  taste,  mind  and  morals. 

—  Rev.  M.  Finnegan 


SAYING  IT  WITH  WORDS 

7528  Tripp  St. 
Skokie.  111. 
Editor,  QST: 

Aren't  you  guys  getting  a  little  stuffy  in  that  rarified 
West  Hartford  atmosphere?  While  I  agree  with  your  Q-R- 
Mary  editorial  in  the  August  issue  of  QST  on  the  abuse  of 
phonetics,  I'm  out  of  phase  with  you  when  you  criticize  the 
use  of  Q  signs  in  'phone  conversation. 

Every  profession,  racket,  sport  or  hobby  has  its  own 
lingo,  including  Hamdom.  Verbal  use  of  the  Q  code  is  no 
more  reprehensible  than  a  doctor  referring  to  an  "OB" 
case;  a  policeman  mentioning  a  "  B  of  I "  record;  or  a  soldier 
talking  about  his  "ID"  card. 

What's  wrong  with  a  'phone  man  saying:  "Sorry,  buddy, 
but  the  QRM  got  you  that  time.  If  you  can  QSY  up  a 
kaycee  or  two,  maybe  we  can  continue  this  QSO.  If  I  don't 
hear  you  again,  don't  forget  that  QSL.  My  QTH  is  okay  in 
the  callbook."  What's  so  bad  about  that? 

Assuming  the  other  guy  has  been  a  ham  for  at  least  a 
week,  I'm  sure  he  would  know  what  I  was  talking  about. 
And  if  he  didn't,  he'd  look  up  those  Q  signals  in  a  hurry. 
How  would  he  ever  use  them  on  c.w.  if  he  didn't  know  what 
they  mean  on  'phone? 

If  you're  really  serious  about  this,  you'd  better  start 
revising  your  own  Handbook.  The  terms  BCI,  TVI,  VFO, 
r.f.,  i.f.,  and  so  on,  are  used  rather  profusely.  To  quote  your 
ovra  editorial:  "Say  it  with  words."

P.  O.  Box  188 
Chester,  Vt. 
Editor,  QST: 

...  I  think  that  misuse  and  excessive  use  of  phonetics 
in  the  'phone  bands  may  be  due  to  several  factors. 

Most  of  us  began  as  SWLs,  and  when  we  got  our  tickets 
we  fell  into  the  habits  of  those  we  listened  to.  Once  we  were 
on  the  air  we  tended  to  perpetuate  the  habits  because  those 
with  whom  we  talked  had  themselves  been  "trained"  and 
in  turn  passed  along  their  methods  of  operating,  which 
we  aped. 

Most  important  is  the  tendency  of  any  group  of  persons 
engaged  in  a  specialized  operation  to  develop  a  "lingo"  of 
"trade  talk"  for  intercommunication.  But  whereas  such 
specialized  speech  often  serves  continuing  needs  in  trades, 
in  ham  radio  time-saving  c.w.  abbreviations  have  been 
adopted  by  'plione  men  as  a  sort  of  badge  of  the  amateur. 
In  using  phonetics  they  feel  more  like  their  conception  of 
what  a  ham  should  sound  like;  it  makes  them  feel  that  they 
now  belong  to  the  fraternity.  This  tendency  can  be  heard 
by  listening  to  those  hams  newly  bitten  by  the  "  traffic  bug" 
who  phonetisize  all  over  the  place  and  adopt  a  clipped, 
terse,  snappy  delivery  in  imitation  of  what  they  believe  to 
be  the  "Ijest"  communications  style.  These  hams,  in  turn, 


are  heard  by  SWLs  who,  admiring  the  "professional"  tech- 
nique, become  conditioned  and  thus  perpetuate  the  system 
when  they  become  hams. 

In  this  manner  the  cycle  continues.  At  worst,  excessive 
phonetics  annoy  those  who  abhor  wasted  time  and  in- 
efficiency. At  best,  they  satisfy  those  using  them  that  they 
are  "real"  hams. 

The  least  that  all  of  us  can  do  in  any  contact  is  to  size  up 
the  situation  quickly  at  the  beginning,  use  phonetics  where 
confusion  might  arise,  and  speak  normally  and  distinctly 
throughout  the  contact.  .  .  .

SHADES  OF  THE  WOUFF  HONG 

P.  O.  Box  59 
Beverly  Hills,  Calif. 
Editor,  QST: 

In  the  August  issue  of  the  American  Heritage  there  is  an 
article  on  the  early  days  of  radio  as  told  by  several  of  the 
men  who  were  in  at  the  beginning,  including  former  Presi- 
dent Hoover  who,  as  Secretary  of  Commerce,  had  much  to 
do  with  formulating  the  laws  and  regulations  governing 
communications. 

I  quote  the  following  from  this  article: 

"The  small  boys  in  radio  were  a  constant  interest  to 
me.  Having  their  own  wave  band  they  had  established  an 
association  of  radio  amateurs  with  whom  we  dealt  con- 
stantly. 

"One  day  I  asked  them  how  they  were  going  to  deal 
with  enforcing  the  assignments  of  their  wave  band  to  pre- 
vent interference. 

"The  president  of  the  association  said,  'Well,  I  don't 
think  you'd  like  to  know  what  we  do.' 
"  'Oh,  yes,'  I  said,  'I  would.' 

"He  said,  'Well,  we  just  take  the  fellow  out  and  beat 
him  up.'  " 

The  mystery  of  the  Wouff  Hong  finally  solved!

I  doubt  very  much  whether  we  would  have  been  able  to

MORE  ON  SYMBOLS 

67  Bro&d  St. 

New  York  4,  N.  Y. 
Editor,  QST: 

The  several  letters  published  in  QST  regarding  the 
new  standard  graphical  symbols  are  most  encouraging  for 


48 


QST  for 


although  they  object  to  a  change  they  find  little  fault  with 
the  symbols  themselves. 

It  is  curiously  human  that  while  we  all  insist  on  being 
proponents  of  progress,  we  view  with  great  suspicion  any 
new  proposal  that  will  make  us  act  or  think  differently 
than  in  the  past.  We  are  all  too  willing  to  declare  such 
proposals  to  be  the  act  of  some  hidden  despot  for  certainly 
it  cannot  be  progress  if  we  must  change.  Fortunately,  time 
heals  all  woimds,  even  those  inflicted  by  standardization. 

Ever  since  the  first  ca\'e  man  selected  those  stones  that 
fitted  most  comfortably  into  his  hand  and  consequently 
made  the  best  weapons,  we  have  had  standards.  His  hand 
became  a  rough  "go  -  no  go"  gauge.  Since  then,  standards, 
both  written  and  unwritten,  have  provided  us  with  simple 
routine  answers  to  questions  that  are  met  frequently.  They 
are,  in  effect,  a  set  of  habits  that  we  purposely  set  about  to 
learn  because  we  know  we  will  benefit  from  them. 

The  whole  structure  of  amateur  radio  is  based  on  stand- 
ards, some  of  which  are  purely  legal  but  most  of  which  are 
arbitrary.  The  frequency  bands  in  which  we  operate,  types 
of  emission,  maximum  power,  the  telegraph  code,  abbrevia- 
tions and  Q  signals,  operating  procedures,  and  a  host  of 
other  everyday  things  are  carefully  planned  standards, 
seldom  of  the  amateurs'  making  and  changed  as  time  and 
conditions  dictate.  .  .  .

.  .  .  MIL-STD-122  obligates  those  of  us  who  earn  our 
dough  in  making  electronic  equipment  for  the  services  to 
use  the  new  and  "distasteful"  symbols.  Most  of  us  don't 
draw  enough  schematics  as  hams  in  this  era  of  store-bought 
equipment  to  become  rapidly  accustomed  to  any  change. 
I  personally  allowed  myself  one  frightful  grimace  and  then 
got  busy  getting  used  to  them.  I  don't  believe  the  majority 
of  guys  would  seriously  want  to  stick  with  the  old  symbols 
if  they  knew  that  the  commercial  designers  are  switching 
over.  How  do  the  "die-hards"  propose  to  convert  to  ham 
use  the  dandy  BC- 1099785  they'll  buy  surplus  in  1960  if 
it's  diagram  is  expressed  in  symbols  used  only  by  the 
commercials?  .  .  .

A  KIND  OF  PLAGUE 

.504  N.  Michigan 
CJlendora,  Calif. 
Editor,  QST: 

Not  long  ago  I  became  aware  of  a  special  type  of  operating 
that  couldn't  be  blamed  entirely  on  lid  operators.  After 
much  research  into  the  matter  I  found  that  this  person  was  a 
sufferer  of  that  dreaded  disease,  Vacume  Cranium  Callites, 
which  is  especially  contagious  to  new  operators. 

I  have  mentioned  below  some  of  the  easily  recognizable 
symptoms  and  simple  cures. 

The  symptoms  are : 

1)  Spasmodic  sending  often  bearing  a  resemblance  to  CQ. 

2)  A  jumble  of  dits  and  dahs  (his  call)  interspersed  once 
every  1}^  to  2  minutes. 

3)  A  break  for  listening  every  5  to  7  minutes  at  which 
time  the  suflferer  of  this  terrible  malady  sometimes 
musters  the  strength  to  tune  2  kc.  each  side  of  wherever 
his  receiver  happens  to  be  set. 

4)  If  he  does  happen  to  hook  up  he  never  sends  each  call 
less  than  5  times  at  the  beginning  and  end  of  each 
transmission. 

Cure: 

1)  Sending  in  step  with  an  ARRL  practice  tape. 

2)  Get  a  free  copy  of  Operating  an  Amateur  Radio  Station 
from  the  ARRL. 

3)  Examine  your  operating  practice. 

4)  Use  your  head.

DX-CURED  HAM 

APO  102 

San  Francisco,  Calif. 

Editor,  QST: 

Greetings  from  Korea,  "the  land  of  the  morning  calm." 

In  my  visit  to  this  lonely  far  eastern  peninsula  I  have  dis- 


covered a  cure  for  the  despised  DX  hog  which,  I  believe, 
surpasses  even  the  wrath  of  the  Old  Man  or  the  fearsome 
Rettysnitch. 

The  picture:  The  QTH  here  is  within  shouting  distance  of 
such  prefixes  as  VSl,  2,  4,  and  6,  VKs,  KL7s,  KAs,  KRs, 
JAs,  VU2,  AC4,  and  Europeans  and  South  Americans  by  the 
dozens  along  with  many  others.  Most  of  these  are  heard 
regularly  on  20-  and  40-nieter  'phone  and  c.w.  with  S9-plus 
signals  and  no,  repeat  no,  QRM  from  W  stations. 

The  rig  here  is  a  BC-610  with  500  cool  watts,  and  the 
receivers  are  a  pair  of  Collins  51Js.  Antennas  are  your 
choice  of  doublets  cut  to  frequency,  long  wires,  or  verticals. 
There  are  also  plenty  of  high  mountains  for  those  who  dream 
of  stacked  rhombics,  etc.  The  emission  is  on  'phone,  c.w.,  or 
RTTY  for  those  guys  who  like  to  have  a  big  TFC  count. 
In  addition,  the  entire  rig  is  mobile  on  a  large  truck  with  a 
10-kw  a.c.  generator  if  you  like  a  change  of  scenery  from 
time  to  time. 

The  qualifications:  All  you  need  is  a  hoggish  interest  in 
working  DX  and  a  Signal  Corps  high-speed  radio  operator's 
MOS,  plus  overseas  orders  for  Korea.  The  orders  are  all  too 
easy  to  get,  hi. 

The  catch:  Amateur  radio  operation  with  the  Army 
equipment  I  just  described  is  strictly  illegal  in  Korea.  So  all 
you  can  do  night  after  long,  long  night  is  just  sit  and  listen 
while  the  rare  DX  booms  in.  (Unless  you  want  to  take  a  good 
chance  of  losing  your  rank,  ham  ticket,  and  about  10  years 
of  your  freedom  by  turning  pirate.)  They  have  monitor 
stations  over  here,  too. 

The  cure:  After  16  months  of  just  listening  like  this  and 
tearing  your  hair  out  you  will  become  either:  (1)  a  reformed 
man  and  honest  DX  chaser,  (2)  a  drunken  derelict,  or  (3) 
a  babbling  idiot.  In  my  own  sad  case  I  already  lean  dan- 
gerously toward  this  third  alternative  after  only  a  few 
months  of  exposure  to  this  horrible  cure.  However,  if  I 
manage  to  survive  these  next  crucial  months  I  shall  see 
you  on  20-meter  c.w.  from  the  good  old  Stateside  QTH.  In 
the  meantime,  I  can  only  hope  that  my  poor  miserable 
replacement  will  be  the  fellow  that  QST  has  voted  as  Mr. 
DX  Hog  of  1955.

BOOK  BANTER 

P.  O.  Box  662 
Nairobi,  Kenya 
Editor,  QST: 

Some  little  time  ago  I  came  across  a  copy  of  your  Radio 
Amateur's  Handbook  —  it  was  being  used  as  a  building 
block  by  a  very  young  acquaintance.  I  rescued  this  some- 
what tattered  copy  and  at  once  realized  that  it  was  a  master- 
piece of  ingenuity,  organization  and  clarity.  Being  somewhat 
of  an  enthusiast  at  that  time  it  became  a  sort  of  bible  of 
radio  to  me.  I  can  honestly  say  that  I  learned  more  from 
your  book  than  from  a  collection  of  others  costing  some  30 
pounds  or  so. 

I  have  today,  at  great  inconvenience,  managed  to  secure 
your  latest  copy,  an  absolute  gold  mine,  for  40  shilhngs.  It 
seems  to  me  that  with  the  general  run  of  such  texts  the  au- 
thor is  at  great  pains  to  point  out  his  own  magnificent  in- 
telligence and  learning.  Teaching  seems  to  be  of  secondary 
importance  in  spite  of  five  or  six  pages  in  the  introduction 
enlivened  with  persuasion  to  the  contrary. 

Why  is  it  that  American  texts,  I  find,  are  so  clear  and  con- 
cise, with  an  invaluable  knack  of  guiding  the  seeker  after 
knowledge  painlessly  on  through  the  pitfalls  of  learning. 

However,  I  have  now  donated  the  old  copy  to  my  African 
assistant  who  also  aspires  to  be  a  radioman.  The  new  copy 
could  not  be  torn  from  me  with  \nld  horses. 

...  I  wish  you  aU  the  strength  in  the  world  and  hope 
you  will  continue  your  work  for  many  decades  to  come.

Editor,  QST: 

During  the  last  few  years  I  have  collected  and  read,  cover 
to  cover,  most  of  the  League's  major  publications.  The 
Handbook,  for  instance,  is  the  bible  of  the  amateur  and  those 
even  mildly  interested  in  amateur  radio.  But  your  v.h.f. 
section  has  been  somewhat  ignored  in  view  of  the  recent 
swing  to  the  higher  bands. 

It  is  my  suggestion  that  the  League  publish  an  "ARRL 


October  1955 


49 


V.H.F.  Handbook"  and  include  in  it  the  many  articles  that 
have  been  WTitten  about  v.h.f.  equipment  in  the  last  few 
yoars.  I  started  to  prepare  a  representative  list  of  things  that 
could  be  included,  but  gave  up  as  it  could  really  get  to  be 
monstrous.  But  sections  on  v.li.f.  propagation,  receivers, 
transmitters  and  antennae  coidd  certainly  round  out  a  good 
publication  to  say  nothing  of  the  advertising  you  could  get 
from  the  many  makers  of  v.h.f.  equipment. 

In  short,    I'd  say   that  a  v.h.f.   handbook   would  be  a 
worth-while  addition  to  the  League's  fine  line  of  publications. 

I  would  appreciate  any  comment  on  my  idea  although 
I  doubt  if  it  is  original  with  me.

LISTENER'S  ADVICE

Re:  SWL  Davis'  letter  in  July  QST.  Mr.  David  can  get  a 
100%  return  to  his  SWL  cards  if  he  can  perform  only  one 
feat  —  tell  the  amateurs  just  one  good  reason  why  they 
should  waste  their  time  and  money!  I  agree  wholeheartedly 
with  V02AW,  having  been  deluged  with  SWLs  myself.  I 
think  we  liams  should  write  SWL  Davis  saying,  "I  collect

we'd  get.

Espanola,  Ontario 
Editor,  QST: 

The  two  letters  headed  "Listener  Reports"  on  p.  142 
of  the  July  issue  of  QST  merit  thoughtful  consideration  by 
all  SWLs. 

Since  going  to  high  power,  a  VO  is  deluged  with  SWL 
cards  —  worthless  to  him. 

Meanwhile,  an  SWL  on  Guam  says  he  doesn't  have  too 
much  trouble  hearing  stations  all  over  the  world. 

Now  a  little  bit  of  evidence  from  me.  I  run  a  30-watt 
Heathkit,  and  for  the  past  few  months  have  run  an  un- 
successful sked  with  a  G.  (I  have  had  many  W  and  VE 
QSOs,  naturally.)  I  would  like  some  evidence  that  m.v  signal 
is  going  somewhere  off  this  continent.  In  other  words,  SWL 
cards  would  be  useful  to  me.  Do  I  ever  get  any?  Not  on  vour 
life! 

The  moral,  Mr.  SWL,  is  that  if  you  can  "hear  him  with- 
out too  much  trouble,"  you  won't  get  a  card.  Instead,  learn 
code  (10  w, p.m.  is  ample  for  this  kind  of  thing)  and  dig  down 
through  the  QRM  and  QRN  to  find  the  lower-power  station 
who  is  calling  CQ  without  success.  He  has  a  haunting  feeling 
that,  despite  the  tests  he  has  made,  and  the  winking  of  the 
neon  bulb  on  the  antenna  tuner,  he  is  not  getting  out.  He 
will  s"nd  you  a  grateful  QSL  —  International  Ref>ly  Cou|ion 
or  not. 

So,  Mr.  Davis,  14.02,  Saturda.vs  and  Sundays,  1600- 
2000  GMT,  for  the  first  4  iiiinutes  of  the  liour,  if  you  really 
would  like  a  W.  card,

Editor,  QST: 

I  have  heard  quite  a  few  Ws  complaining  about  DX  sta- 
tions not  QSLing  100  per  cent  so  I  have  made  a  list  of  per- 


centages of  W  QSLs  received  here  at  KL7AQU.  Here  it  is: 
Wl— 30%,  W2  — 45,  W3  — 75,  W4  —  4,  W5  —  25,  W6 
—  65,  W7  —  60,  W8  —  65,  W9  —  30,  W0  —  90. 

This  is  from  2000  QSOs  over  a  period  of  2  years.  I  wonder 
how  this  compares  with  DX  station  QSL  percentages. 
What  say,  Ws'?

SKY'S  THE  LIMIT 

Orchard  Lane  &  EUicott  Rd.

Editor,  QST: 

We  have  always  read  with  considerable  stimulation  your 
extracurricida  articles  on  the  aurora  borealis,  meteor  scat- 
tering and  "Project  Moonbeam"  to  mention  a  few.  For 
those  scientifically  and  experimentally  minded  we  recom- 
mend Prof.  Kraus'  article  on  "Radio  Telescopes"  in  the 
March  issue  of  Scientific  American.  For  those  who  like  to 
build  complex  arrays,  here  they  can  build  an  array  of  dipoles 
1500  feet  long  or  a  parabolic  dish  reflector  250  feet  in 
diameter  if  they  wish. 

The  fact  that  there  are  many  stars  emitting  tremendous 
quantities  of  radio  energy  should  open  up  a  new  field  for  the 
amateur  experimenter,  and  as  for  one  who  feels  like  Colossus 
with  his  1  kw.,  let  him  contemplate  one  of  the  objects  in  the 
sky  called  Cygnus  A  which  astronomers  estimate  radiates 
in  a  single  second  enough  radio  energy  to  supply  the  earth's 
requirements  of  heat  and  power  for  the  next  trillion  years 
if  converted  and  translated  to  heat.

22nd  ARRL  Sweepstakes  — 
12th-13th  and  19th-20th 

How  many  ARRL  sections  and  how 
many  stations  in  those  sections  can  you 
work  in  two  week  ends.*  If  j^ou  are  located 
anywhere  in  the  League's  field-organiza- 
tion territory  (see  page  6),  you  are  cor- 
dially invited  to  take  part  in  this  popular 
annual  operating  activity.  Any  amateur 
bands,  'phone  or  c.w.,  may  be  used.  The 
total  operating  time  allowed  each  con- 
testant is  40  hours.  'Phone  entries  are  com- 
pared only  with  other  'phone  entries  — 
c.w.  scores  only  with  other  c.w.  scores  — 
in  your  particular  section,  in  the  competi- 
tion for  awards.  The  week-end  periods 
starting  Saturday  afternoon  (1500  PST 
or  1800  KST)  on  the  12th  and  19th  of 
November  mark  the  open  season  for  SS 
contacts. 

A  complete  aiuioimcement  of  the  con- 
test, including  the  rules  governing  partici- 
pation, will  appear  in  November  QST. 
The  rules  will  be  the  same  as  those  of  tlie 
1954  SS.  Amateurs  in  remote  ARRIj  s(>c-

usual  W6  activity  are  missing  this  year,  for  an 
understandable  reason.  The  YLRL's  first  Inter-

can't  afford  not  to  take  part  in  Hamdom's  most

1955  AWTAR 

For  the  fourth  year  the  pilots  who  flew  in  the  1955  AU- 
Women  Transcontinental  Air  Race  had  the  assistance  of 
amateurs  throughout  the  countrj\  Race  information,  such 
as  take-off  and  arrival  times,  weather  conditions,  progress 
reports,  etc.,  was  relayed  by  a  network  of  more  than  one 
hundred  amateur  stations  from  the  start  on  July  2nd  at 
Long  Beach,  Calif.,  to  the  finish  on  July  6th  at  Springfield, 
Mass.  Serving  for  the  third  consecutive  term,  Betty  Gillies, 
W6QP1,  was  Air  Chairman  for  the  Ninth  Annual  Powder- 
Puff  Derby.  Eunice  Gordon,  WIUKR,  headed  amateur 
operations,  with  Viola  Grossman,  W2JZX,  assisting  her. 
Evelyn  Scott,  W6NZP,  was  again  in  charge  of  radio  opera- 
tions at  Long  Beacli.  Other  Radio  Chairmen  at  each 
stop-over  city  were  as  follows: 

Blythe,  Calif.,  W6FLD;  Phoenix,  Ariz.,  YL  Janis  Ken- 
nedy, W7PWU  Tucson,  Ariz.,  W7LAD;  El  Paso,  Tex., 
WoKBP  and  W.5IAF  Midland.  Tex.,  W5GGC  and  WoGOS; 
Wichita  Falls,  Tex.,  YL  Garlena  Powell,  W.5QJZ;  Tulsa, 
Okla.,  W5PA:  Springfield,  Mo.,  W0HUI;  St.  Louis,  Mo. 
W9YVVL  and  W0MSX;  Terre  Haute,  Ind.,  W9ZHL; 
Dayton,  Ohio.  \V8FPZ  and  KL7PIV/W8:  Wheeling,  W.  Va., 
W8PHY  and  W8KXD:  Reading,  Pa.,  W3PFT. 

Others  who  assisted  the  various  chairmen  were  WIKUL, 


W3BN.  W5UUR,  W8DWT,  W8YFX,  W0DLS,  W0VZC, 
W0PUS  and  YLs  W2KEB,  K6CPX  and  W6LMQ.  Copy 
deadline  prevents  a  complete  list  of  participating  amateurs 
in  this  issue. 

Ninety-two  participants  flew  in  54  300-horsepower-or-less 
aircraft.  Flying  a  Cessna  180,  Mrs.  Frances  Bera  of  Los 
.\ngeles,  with  her  sister  Mrs.  Edna  Bower  of  Long  Beach 
as  copilot,  placed  first  in  the  handicap.  The  plane  that 
placed  third  was  piloted  by  WIYUO,  Jerry  Gardiner,  of 
Waterford,  Connecticut. 

Portable  or  mobile  stations  operated  directly  from  the 
airport  at  each  stopover  city.  Conditions  on  75  and  20,  the 
two  bands  used,  were  reported  very  good  by  WIUKR, 
who  actually  lived  at  the  Barnes- Westfield  Airport  for  six 
days.  Operators  at  Springfield  monitored  on  20  meters  the 
take-off  at  three-minute  intervals  of  the  planes  from  Long 
Beach. 

At  a  post-race  banquet,  members  of  The  Ninety-Nines, 
Inc.,  sponsors  of  the  race,  expressed  their  appreciation  to 
Eunice  for  the  valuable  assistance  that  the  amateurs  had 
given  to  them.  The  husband  of  one  of  the  flyers  remarked: 
"I  used  to  have  to  sweat  it  out,  not  knowing  where  my  wife 
was,  nor  how  she  was  progressing.  Now,  thanks  to  you 
hams,  I  can  literally  follow  her  everj^  mile  of  the  course."

TRANSISTOR  TRANSMITTER  DX 

4815  S.W.  Patton  Road 
Portland  1,  Ore. 
Technical  Editor,  Q&T: 

From  the  standpoint  of  interest  in  the  use  of  transistors 
on  the  amateur  frequencies,  I  submit  the  following  for 
whatever  value  it  may  have. 

Using  a  transistor  and  running  1.8  mw.  I  worked  the 
following  stations : 

August  22nd  —  W7DIS,  Portland,  Ore.,  approximately 
2  miles  air  line. 

August  23rd  —  WN7AAV,  Salem,  Ore.,  approximately 
45  miles  air  line. 

August  24th  —  W7TNF,  Astoria,  Ore.,  approximately 
85  miles  airjline. 

The  transistor  transmitter  is  crystal  controlled  on  3701  kc. 
The  W7DIS  and  W7TNF  QSOs  were  arranged,  but  the 
WN7AAV  QSO  was  not.  The  reports  were  W7DIS,  339; 
W7TNF,  449;  WN7AAV,  369. 

On  August  25th,  contact  was  made  with  W7WPR,  using 
the  transistor,  running  2.5  mw.  input.  W7WPR  is  in  Seattle, 
Washington,  approximately  200  miles  away,  and  a  459 
report  was  received.  He  was  receiving  me  on  an  SX-25 
receiver  and  a  folded-dipole  antenna. 

The  transistor  used  in  this  circuit  is  a  Motorola  type 
XN-2  PNP  junction  transistor.  It  is  primarily  designed  to 
operate  at  frequencies  around  455  kc,  but  experiments 
have  sho^vn  that  it  operates  very  satisfactorily  at  fre- 
quencies in  the  80-meter  band. 

Maximum  (absolute)  ratings  of  tliis  transistor  are: 
Collector  volta  minus  10 

Collector  current  minus  2  ma. 

Collector  dissipation  20  mw.  at  25  degrees  C

TUNING 
INDICATOR 


The  transistor  transmitter  at  W7UUZ  uses  a  Motorola 
type  XN-2  PNP  transistor.  L\  tunes  to  3.5  Mc.  with  the 
capacitor  fully  meshed.  L2  in  the  tuning  indicator  is 
a  6-  to  8-turn  pick-up  loop. 

Tuning  the  transistor  transmitter  is  relatively  easy,  and 
the  only  precaution  worth  mentioning  is  that  the  collector 
current  must  not  exceed  the  maximum  ratings  of  the  transis- 
tor used.  To  preclude  this  possibility,  the  arm  of  the  potenti- 
ometer should  initially  be  at  the  ground  end. 

The  tuning  procedure  then  is  first  to  turn  the  receiver  to 
the  frequency  of  the  crystal  used.  Apply  the  collector 
voltage  (make  sure  that  the  arm  of  the  potentiometer  is 
turned  to  the  grounded  end).  Turn  the  potentiometer  up 
until  the  miUiamnieter  reads  approximately  IJ^  ma.  Then 
tune  the  tank  condenser  until  maximum  current  is  indi- 
cated (do  not  exceed  2  ma.).  If  it  starts  to  go  over  2  ma. 
return  the  arm  of  the  potentiometer  closer  to  the  groimd 
end  (this  much  will  indicate  that  the  circuit  is  oscillating). 
Connect  the  antenna  and  go  through  the  same  procedure, 
always  being  careful  not  to  exceed  the  maximum  ratings  of 
the  transistor  (tests  have  shown  that  in  c.w.  service  currents 
of  up  to  4  ma.  will  not  harm  a  transistor  of  this  type). 

Because  of  the  small  available  output  I  found  that  it  was 
very  difficult  to  tune  the  antenna  to  resonance.  Using  a  few 
turns  of  coil  with  a  1N34  diode  and  a  0-2.50  microaiumeter 
makes  for  a  very  sensitive  tuning  indicator.  Loading  of  the 
tuning  network  with  this  gimmick  will  cause  the  circuit  to 
go  off  resonance,  and  when  tlie  instrument  is  removed  maxi- 
niimi  transfer  of  the  signal  to  the  antenna  has  dropped  off.

Annual 
Simulated  Emergency  Test 

(October  8-9,  1955) 

By  the  time  this  appears  in  print,  all  EC's,  SECs,  and 
SCMs  will  have  received  a  copy  of  the  "SET  Bulletin" 
outlining  details  and  last-minute  instructions  concerning 
the  ARRL's  annual  Simulated  Emergency  Test.  This 
announcement  is  for  the  benefit  of  all  amateurs,  so  that 
you  will  know  ahout  the  imminence  of  the  test  and  have  a 
general  idea  how  it  works  and  what  to  do  if  you  wisli  to 
take  part. 

The  SET  is  nut  a  contest.  It  is  tlie  annual  test  of  AREC 
facilities  in  conjunction  with  the  principal  agencies  we 
serve.  Each  AREC  organization  will  attempt  to  better  its 
last  year's  score,  so  the  scoring  system  will  be  the  same  as 
in  pre\'ious  years.  Here's  a  brief  run-down  of  how  the  SET 
works : 

1)  The  EC  calls  a  surprise  alert  of  his  AREC  organization 
sometime  during  the  October  8th-9th  week  end.  If  another 
date  is  more  convenient  for  local  reasons,  such  an  exercise 
can  be  counted  as  the  SET  exercise.  Conduct  your  drill  on 
the  designated  week  end  if  you  can. 

2)  The  group  conducts  a  simulated  emergency  test  under 
the  EC's  direction.  The  test  may  be  slanted  toward  natural 
disaster  (with  Red  Cross  participation,  if  feasible)  or  enemy 
attack  (in  coordination  with  local  civil  defense).  During  the 
test,  each  local  participant  should  dispatch  a  message  in 
standard  ARRL  form  to  the  EC,  indicating  liis  presence  and 
availability,  or  anything  else  the  EC  directs. 

3)  The  EC  dispatches  a  message  to  ARRL  Headquarters 
briefly  describing  the  test  and  mentioning  calls  of  parti- 
cipants. 

4)  At  the  EC's  solicitation,  the  local  Red  Cross  Disaster 
Chairman  (or  other  official)  dispatches  a  message  to  the 
American  National  Red  Cross  in  Richmond,  Va.,  %ia 
amateur  radio,  reporting  Red  Cross  participation  in  the  test^ 

5)  Also  at  the  EC's  solicitation,  the  local  Civil  Defense 
Director  dispatches  a  message  by  amateur  radio  to  his 
State  Civil  Defense  Director  reporting  civil  defense  partici- 
pation in  the  test,  if  any.  This  is  a  job  for  the  SEC  and  state 
or  section  traffic  and  emergency  nets.  A  list  of  state  directors 
is  included  in  the  SET  Bulletin. 

6)  The  local  press  is  brought  into  tlie  exercise  for  the 
maximum  in  publicity.  ARRL  sends  out  a  publicity  release, 
but  your  best  publicity  is  generated  at  the  local  level.  Imite 
the  press  to  your  exercise. 

7)  Some  time  during  the  October  8th-9th  week  end,  a 
Test  Emergency  Alert  (TEA)  message  will  be  transmitted 
on  the  National  CaUing  and  Emergency  Frequencies.  If 
you  copy  the  message,  send  vis  a  radiogram  indicating 
you  copied  it  (gi\'ing  station  from  which  copied,  date, 
time  and  frequency),  then  send  ue  a  confirming  copy  of 
the  complete  message  (not  just  the  text)  by  mail,  you'll 
get  special  QST  mention  in  the  SET  write-up.  Last  year 
the  message  was  sent  by  T\'1AW  only  once  on  c.w.  and 
once  on  'phone.  This  year  we  hoi^e  to  have  it  sent  more 
often,  and  by  stations  in  the  Midwest  and  Far  West  also, 
if  possible.  Keep  your  receiver  tuned  to  one  of  the  National 
Calling  and  Emergency  Frequencies  during  the  week  end 
and  you  can't  miss  it. 

8)  After  the  test,  tlie  EC  rejiorts  details  on  a  form  ]iro- 
vided  witli  the  Bulletin.  See  thai  yours  reporls.  no  i/oiir  irork 
will  receive  credit. 

WlAW  and  other  stations  operated  by  ARRL  staff 
members  will  be  active  to  take  incoming  traffic  for  ARRL.

Traffic  for  the  Red  Cross  or  state  civil  defense  offices  can 
follow  regular  routes,  most  of  wlu'ch  are  normally  activated 
on  Saturdays  and  will  be  activated  especially  on  Sundays 
during  the  SET.  If  Amateur  Red  Cross  Stations  W6CX0  (San 
Francisco),  W9DUA  (Springfield,  111.)  and  W3PZA  (Wash- 
ington, D.  C.)  are  able  to  be  active,  they  can  take  traffic  for 
American  National  Red  Cross.  If  you  cannot  clear  your 
hook  on  the  NCE  frequencies,  try  one  of  these:  3640  or 
3880  (for  Conn.),  3680  or  3835  (for  Va.). 

In  Canada,  Red  Cross  traffic  should  be  forwurded  to 
Canadian  National  Red  Cross  in  Toronto,  civil  defense 
traffic  to  Provincial  Civil  Defense  headquarters.  Canadian 
ECs  send  their  SET  reports  to  ARRL,  same  as  all  ECs. 
Designated  Canadian  National  Calling  and  Emergency 
Frequencies  are  3535,  3765,  7050,  14,060,  14,160  and  28,250 
kc. 

If  you  are  not  already  signed  up  in  the  AREC,  now  would 
be  a  good  time  to  get  lined  up  with  your  EC  and  start  your 
public-service  work  right  by  participating  in  the  SET. 
Why  not  look  into  it  locally  and  see  what's  cooking?  We'll 
tell  you  the  name  and  address  of  your  EC  (if  any)  if  you 
don't  already  know  it. 

See  you  on  October  Sth-9lh  in  the  SET,  OM?

QST  for 


CONDUCTED  BY  ROD  NEWKIRK,*  W9BRD 


t 


'Ow: 

^^'hen  an  unbeliever  (stranger  to  amateur 
radio)  pays  a  visit  to  j^our  hamshark,  chances 
are  you're  more  than  a  Uttle  perplexed  at  the 
naive  questions  put  to  you.  One  such  BCL-type 
acquaintance  of  Jeeves'  early  Oxford  gyp  days 
called  on  us  recently  and  performed  true  to  this 
form.  After  those  two  well-qualified  quidnuncs 
put  the  Boss's  brandy  stock  to  rout  Jeeves 
brought  the  chap  into  our  shack.  Their  discon- 
certingly discursive  conversation  took  the  fol- 
lo\\ing  course.  .  .  . 

Guest:  Good  'eavens,  .I.J.  —  'ow  far  do  you  communicate 
«-ith  this  curious  apparatus? 

Jeei'es:  Boundless,  boundlessly  far,  Reginald.  On  a  still 
evening  we  may  be  detected  inside  Outer  Mongolia,  you 
know. 

Guest:  'Zooks!  And  you  constructed  this  gadgetry  en- 
tirely yourself,  J.J.? 

Jeeves:  Not  quite,  old  top.  The  factory,  you  know. 

Guest:  Those  gaily-lettered  pasteboards  on  the  wall.  .I.J. 
■ —  some  sort  of  optoraetrical  claptrap,  what? 

Jeeves:  Oh,  an  uncommonly  rare  collection  of  long- 
distance QSLs,  Reginald.  Uncommonly  rare.  The  Boss 
conducts  a  DX  column  —  samples,  you  know. 

Guest:  I  observed  no  aerial  outside,  J.J.,  yet  I  would 
imagine  one  should  require  an  imposing  structure  to  radiate 
such  great  distances.  Incongruous,  what? 

Jeeves:  The  neighbors,  Reginald  —  we  had  one  up  this 
morning.  Moreover,  the  Boss  is  using  his  underground 
antennae  for  Ceylon.  Straight  down,  you  know. 

Guest:  Doubtless  much  i^ower  is  consumed  by  this  vast 
thingamabob.  Expensive,  what? 

Jeeves:  Riglito,  Reginald,  the  meter  does  whirl  a  bit. 
But  not  as  furiously  as  formerly.  Jumper,  you  know. 

Guest:  I  cnce  'eard  of  a  wireless  chappie  who  made  quite 
a  nuisance  of  himself.  Downright  rum  performance  — 
'arrassed  local  video,  the  wireless,  gramaphoncs  and  what 
not.  Are  you  faced  with  such  a  lot,  J.J.? 

Jeeves:  A  ripping  amount  once,  Reginald,  but  negligible 
now.  Silent  hours,  you  know. 

Guest:  Wires,  boxes,  switches,  valves  and  more  wires  I 
I  say,  J.J.,  'ow  do  yo\i  manage  to  tidy  it  up? 

Jeei-es:  Elementary,  dear  Reginald.  I  shove  off  into  the 
cellar,  open  all  switches  and  remove  all  fuses  beforehand. 
Silent  Keys,  you  know. 

Guest:  I  say,  J.J.  old  bean,  my  brother-in-law's  solicitor's 
nephew  in  Sussex  is  a  wireless  bug.  Do  you  suppose  you 
could  chat  with  'im  and  permit  me  to  shout  a  cheerio  back 
'ome?  Do  you  really,  now? 

Jeeves:  Nothing  to  it,  Reginald.  But  as  you  do  not  know 
liis  call  sign  I  shall  have  to  call  "CQ  Reginald's  brother- 
in-law's  solicitor's  nephew  in  Sussex."  Beastly  cumber- 
some, you  know.  .  .  . 

Well,  the  imperturbable  Jeeves  had  his  usual 
smooth  answer  for  everything  but  surely  he  was 
going  overboard  on  that  one.  \'isitors  who  have 
ham  acquaintances  they  want  you  to  contact  on 
the  spur  of  the  moment  ^\'ithout  schedules,  call 
signs  or  other  clews  —  hah!  Just  "'give  Egbert  a 
call  and  let  me  say  hello  to  him."  A  million  to 
one  would  be  comfortable  odds. 


*  Please  mail  all  reports  of  DX  activity  to  DX  Editor 
Newkirk  at  4128  North  Tripp  Ave.,  Chicago  41,  lUinois. 


But  would  _\ou  believe  it?  After  Jeeves  com- 
pleted a  short  "CQ  Reginald's  brother-in-law's 
solicitor's  nephew  in  Sussex,"  back  came  a 
clipped  British  voice  on  the  frequency  saying, 
■'.  .  .  This  is  Reginald's  brother-in-law's  solici- 
tor's nephew,  CiSZZZ  in  Sussex,  returning. 
Thanks  for  the  call,  you  know."  And  Reginald, 
Jeeves  and  Egbert  conversed  amiably  for  the 
next  two  hours  without  batting  an  eye. 

Anyone  for  the  rest  of  that  brandy?  (Nerves, 
you  know.) 

What: 

Reginald  is  back  on  the  road  for  Schweppes  now,  and 
Jeevesie  has  his  head  down  in  the  mailbag  to  see  what  the 
gang  has  to  say  this  month.  There  are  squeals  of  delight  on 
all  sides,  we  note,  as  we  swing  toward  Old  Sol's  acne  acme 
on  pox  peak.  "Just  had  about  .'?00  Statewide  QSOs  with 
signals  running  to  5  by  5  to  9  plus  40  db.,  the  latter  pre- 
dominating—  all-around  good  Stateside  QSOs.  "  —  HZlAB 
.  .  .  "We've  had  several  days  of  wonderful  long-path 
propagation  la,te\y."  —  ZD6BX  — .  .  .  .  "Twenty  sure  is 
hoppin' these  days  (for  a  change)."  —  W2BRV.  .  .  ."Very 
good  night  openings  to  Europe  for  two  to  four  hours  at  a 
time  and  some  nights  the  band  is  wide  oi>en  all  night  long 
—  guess  that's  a  big  improvement  over  last  vear  at  this 
time."  —  W6GPB.  And  so  it  goes!

recent  month Ex-ET3S,  now  VE3RE,  rolled  up 

155  countries  in  Ethiopia  during  the  period  July  15,  1954, 
to  May  10,  1955,  using  a  4-stage  814  rig,  12-tube  receiver, 
dipoles  and  a  Lazy-H  beam.  Phil  still  awaits  QSLs  from 
some  of  the  rarer  items  logged  although  one  dandy  did 
come  through  from  ZC3AC.  Drop  a  hne  to  VE3RE  if  you 

have  ET3S  QSL  problems WIWPO  points  out 

that  the  present  VQ8AG  attests  to  no  responsibility  or 
connection  with  VQ8AG  operation  prior  to  February  of 
this  year.  Frank  gets  around  on  20  c.w.  quite  handily  with 
a  c.c.  2-stage  20-watter,  a  modified  b.c.  5-tuber  and  a 
long-wire  radiator  ._._._  IIBNU/Trieste,  perhaps  the 
most  active  Il/T  on  DX  bands,  strongly  emphasizes  that 
incoming  QSLs  should  be  sent  only  \'ia  ARI  or  direct  to 
F.  Venezian  5,  Trieste  ._._._  All-band  Faeroes  DX 
champ  OY7ML  asserts  that  Box  184,  Torshavn,  is  the 
sole  QTH  that  ensures  delivery  of  his  incoming  paste- 
boards    From    MP4.TO's  agent,   W2PCI:  "There 

will  be  considerable  delay  in  QSL  cards  from  MP4J0. 
.  .  .  Some  of  the  fellows  are  sending  follow-up  cards  and 
letters  that  are  keeping  me  busy  to  answer  —  just  got  hit 

with  52  cards  in  the  same  mail!" HI8WF,  inactive 

since  July  1st  of  last  year,  knows  nought  about  the  current 

usurper  of  his  call.  —  W6CUQ F08AC  indicates 

he's  now  up  to  snuff  in  the  confirmation  department  after

Asia  —  This  month's  WOYY  one-man  DX  omnibus  is 
ornamented  with  many  an  Oriental  item:  VS2DQ  has 
ZC3  intentions  upon  returning  from  his  L^.K.  holiday. 
He  mentions  one  of  the  hazards  of  hamming  on  Christmas 
Isle  —  gregarious  eight-foot  land  crabs.  .  .  .  VS6BE 
awaits  delivery  of  a  brand  new  KW-1  and  75A-4.  .  .  . 
XZ2KN's  protruding  signal  does  credit  to  a  newly  installed 
6-element  beam.  .  .  .  C3WV  fires  up  several  evenings  per 
week  with  a  BC-610.  51J  and  half-wave  vertical.  Dick  is 
slated  for  return  to  Uncle  Sugar  this  month  and  hopes  his 
relief  will  keep  C3WV  available.  The  other  Formosan 
active.  BVIUS,  is  located  some  150  miles  to  the  south  of 
CSWV's  diggings  ._._._  VS2DW,  who  states  he's  the 
only  nati\-e  Malayan  licensed,  ^\Tites  W9VP  of  DX-band 
trials  and  tribs.  The  Dancing-Witches  BC-610  expired  in 
smoke  some  time  back,  requiring  him  to  fall  back  on  a  e.c. 
6V6-6L6  combo  which,  surprisingly  enough,  performed 
quite  comparably.  Tan  uses  dipoles  and  a  thoroughly  re- 
vamped HRO-M  inhaler.  When  not  performing  official 
duties  as  a  legal  interpreter  in  Ipoh  (now  quite  a  boom- 
town),  VS2DW  hits  20  meters  and  keeps  the  peace  in  a 
household  which  includes  three  sons  and  a  daughter.  His 
particular  pet  peeve  is  the  DXer  who  far  exceeds  the 
bounds    of    eivilitv    in    pursuing    an    inadvertently    tardy 

"First   VS2!"   QSL W"6AM   reports  that  public 

demand  forced  XW8AB  to  scrounge  up  parts  for  a  modu- 
lator after  dispensing  scores  of  Laos  c.w.  QSOs  ._._._ 
W6CRV,  whose  Saudi  Arabia  assignment  was  extended 
a  month,  has  been  assisted  of  late  at  HZIAB  by  the  keying 
and  miking  of  K4DCC  and  W4EGG.  Ron  is  the  DXer  of 
the  group,  though,  and  has  pushed  up  HZlAB's  DX  tally 
to  a  respectable  140/126.  That's  not  at  all  bad  in  -i-iew  of 
limited  on-the-air  tours  and  an  accentuated  traffic  program 

K2IXD,   one   of  OE13USA's   mainstay   ops  for

presentation  of  a  weU-earned  4X4  =  16  DX  award,  ac- 
cepted by  K2IXD  on  behalf  of  0E13USA A  bow

Africa  —  ET3LF  writes  concerning  a  gala  ham  exhibit 
to  be  installed  at  the  Haile  Selassie  I  Silver  Jubilee  Anni- 
versary Fair  which  opens  in  Addis  on  the  second  of  next 
month.  The  Imperial  Board  of  Telecommunications  of 
Ethiopia  intends  to  show  off  amateur  radio  to  advantage. 
"We  plan  mainly  operation  on  20-meter  c.w.  and  'phone 
and,  conditions  permitting,  we  ^"ill  be  on  10  and  15  meters, 
too."  The  call  isn't  specified  but  if  you  encounter  an  ex- 
pertly handled  unfamiliar  ET3  call  early  in  November 
this  should  be  explanatory.  Souvenir  QSLs  doubtless  will 
be  forthcoming  ...._._  With  an  assist  from  buddy  ZD6EF, 
ZD6BX  blossomed  out  with  a  husky  805  final  to  replace 
his  old  trio  of  parallel  807s.  ZD6EF  frisks  about  on  'phone 
with  a  hundred-watter  and  ZD6RM  sprinkles  n.f.m. 
'phone  among  his  many  14-,  21-  and  28-Mc.  c.w.  QSOs. 
(Yes,  we  said  28-Mc.  c.w.!)  "There  may  be  another  ZD6 
active  soon,  solely  on  'phone.  .  .  .  We  now  have  50  Mc. 
open  for  ZD6  fellows  and  gear  for  that  band  already  is 
under      construction."      Whoops^  we're     slipping     into 

WlHDQ's  domain! ZSISW,  who  runs  100  watts 

from  3.5  through  144  Mc,  and  50  watts  on  432  Mc,  sports 
this  variety  of  skybait:  a  320-foot  wire  on  80;  66-footer  on

Oceania  — WIA  (Australia)  and  NZART  (New  Zea- 
land) invite  world-wide  participation  in  the  1955  VK/ZL 
DX  Contest  to  be  held  ('phone)  from  1000  GMT,  October 
1st,  to  1000  on  October  2nd,  and  (c.w.)  from  October  8th 
through  9th,  same  hours.  The  serial  e.xohange  is  the  usual 
five-digit  (A3)  or  six-digit  (Al)  figure—  RSTOOl,  RST002, 
etc.  —  except  that  an  operator  may  commence  operation 
with  any  number  between  1  and  99.  E.g.,  your  first  QSO 
can  be  numbered  RST0()3,  your  second  contact  RST0')4, 
etc.  Any  amateur  band  can  be  used.  Scoring:  One  point 
per  contact,  each  station  to  be  worked  but  once  per  band, 
this  point  total  to  be  multiplied  by  the  combined  numbers 
of  VK/ZL  call  areas  worked  on  all  bands  (ZLl  through 
ZL4;  VKl  through  VK9,  excluding  VK8).  Logs:  For  each 
contact  record  the  date,  GMT,  band,  call,  and  serials 
sent/received  in  that  order.  Use  a  separate  sheet  for  each 
band  and  underhne  each  new  band-area  as  worked.  Attach 
a  summary  sheet  bearing  total  score,  a  brief  station  de- 
scription and  a  signed  declaration  that  rules  have  been 
observed.  Entries  must  be  postmarked  on  or  before  Octo- 
ber 31,  1955,  addressed  to  WIA  Federal  Contest  Com- 
mittee, Box  1234K,  GPO,  Adelaide,  S.  A.,  Australia. 
From  these  will  be  ascertained  winners  of  certificates  to 
be  awarded  high  scorers  in  each  ARRL  DXCC  Countries 
List  country  and  U.  S.  A.  call  area.  Note:  There  is  no  pro- 
vision for  multioperator  work  in  this  competition;  opera- 
tors manning  the  same  station  will  submit  separate  entries 
as  individual  competitors.  Good  fishin'!  ._._._  One 
more  peek  at  WGYY's  dopesheet,  this  time  from  an  Oceanian 
angle:  VR2AB  tried  a  few  QSOs  as  VR2AB/ZM6  this 
summer,  traveling  via  the  Tokelaus  where  he  (sob!)  found 
no  opportunity  to  fire  up.  Friend  VR2BZ  still  entertains 
strong  slant-VR5  notions.  .  .  .  YJIDL,  intermittently 
active  on  20  and  40,  states  that  the  McCoy  YJIAA  has 
not  been  active  during  the  past  year  because  of  power 
deficiencies.  .  .  .  No.  1  WAVKC.\  DX  award  (see  p.  63, 
August  QST)  went  to  W6YY.  .  .  .  All-band  DX  phenoni 
DL'7SV  reached  the  DXCC-mark  in  the  confirmation  de- 
partment. A  hearty  huzzah  for  Volt  —  DU7SV  no  doubt 
could  have  worked  dozens  more  countries  if  he  had  hard- 
heartedly  ignored  the  DU-hungry  W/K  pack  always  yap- 
ping on  his  heels KC6CG  (W2UDI)  has  another 

month  or  two  to  fatten  his  log  before  moving  Jerseyward.

navigating westward. 


Europe  —  K2IXD  (0E13USA)  tells  WlVG  that  OEl3s 
will  be  no  more.  The  advent  of  the  Austrian  Peace  Treaty 
brought  this  about  and  the  resident  OE  crew  will  take 
over  on  DX  bands  in  good  stride.  OE13L'SA  recently 
managed  to  accumulate  the  wherewitlial  for  DXCC  despite 
the  heavy  demands  of  frequent  traffic  skeds  ._._._

Results,  21st  ARRL  DX  Contest 

Entries  Rise  for  Fourth  Straight  Year;  328  Earn  Certificates 
BY  PHIL  SIMMONS,  WIZDP 


"  How  high  can  scores  go  in  an  ARRL  DX 
Contest?  That  question  comes  to  mind  each 
year  ichen  we  analyze  entries  in  these  periodic 
coiUests  of  DX  operating  skill.  And  each  year 
we  say  to  ourselves  in  answer,  '  This  is  it. 
We've  reached  the  leveling-off  point.  It's  im- 
possible for  scores  to  go  any  higher!'  We've 
been  UTong  .  .  .  which  proves  that  impossible 
goals  have  just  not  appeared  on  the  DX  Contest 
horizon,  at  least  not  for  the  experienced  DX 
operator  who  comes  up  annually  with  new 
score  records  or  the  neophyte  who  keeps  im- 
proving .  .  .  in  an  attempt  to  break  into  the 
top  score  brackets.  It  all  adds  up  to  the  fact 
that  these  contests  are  great  builders  of  operator- 
station  performance.  If  DX  is  your  meat,  you'll 
continue  taking  part  and  become  more  skilled 
as  time  goes  on;  if  you're  new  to  DX  operating, 
you  just  haven't  been  indoctrinated  in  the  game 
until  you've  come  through  your  baptism  of  fire 
in  an  ARRL  DX  Contest!" 

THOSE  words,  concocted  by  WIJMY  in  his 
16th  ARRL  DX  Contest  round-up  in  Sep- 
tember 1950  QST,  are  apropos  today.  Again 
the  long-time  enthusiasts  returned,  some  to  register 
postwar  scoring  records,  and  when  the  usual 
generous  helping  of  fresh  converts  is  taken  into 
account,  we  emerge  with  1242  entries  (886  c.w., 
356  'phone),  up  11.5  per  cent  over  1954.  There 
has  now  been  a  steady  participation  increase  — 
'though  scarcely  a  meteoric  one  —  in  each  of  the 
past  four  Tests. 

The  unexpected  makes  every  DX  Test  a  con- 
tinual game  of  fox  and  hounds,  keeps  the  brethren 
hoping  and  hopping.  An  hour  of  fruitless  calling 
elapses  and  you  are  as  discouraged  as  a  wood- 
pecker in  the  Petrified  Forest  —  suddenly  three 
new  countries  reply  in  as  many  minutes  and  all 
thoughts  of  "pulling  the  big  switch"  are  ban- 
ished; now  a  block  and  tackle  couldn't  detach 
you  from  the  operating  position!  This  3'ear 
TI9MHB,  PJ2MA  and  HK0AI,  in  spots  "that 
even  some  DXCC  Honor  Rollers  lack,  injected 
spice.  In  Februarj^,  15  meters  briefly  cleared  for 
Europe,  allowing  alert  code  proponents  to  hijack 


several  multipliers  in  a  short  span.  A  gorgeous 
array  of  African  prefixes  —  including  CR5,  CR6, 
CR7,  CT3,  EA8,  EA9,  EA0,  ET3,  FB8,  FF8, 
KTl,  ST2,  VQ2,  VQ3,  ZD3  — were  catchable. 
KH6IJ  and  W6AM  QSOd  on  7  bands,  and 
W4KFC  did  the  same  with  HK4DP.  W2SKE 
snapped  up  16  countries  on  10  'phone  and  was 
thrilled  to  raise  Africans  there  for  a  change;  Bill 
prophesies  W/'VE  radiotelephone  totals  of  one 
million  points  in  sunspot  peaks  soon  to  arrive. 
The  newly-introduced  rule  whereby  Ws  and  VEs 
identified  their  states  and  provinces  was  happily 
endorsed  by  those  in  far-awaj^  places;  many  kept 
careful  track  of  their  states  worked  and  several 
got  all  48. 

Let  us  pay  tribute  to  such  Test  regulars 
overseas  as  CTISQ,  CT2B0,  CT3AB,  DLIBR, 
DLIDX,  EAIAB,  EA9AP,  EI9J,  F8VJ,  G2PU 
(who  has  earned  the  last  nine  'phone  awards  for 
England),  G5RI,  KH6IJ,  KH6MG,  KTlUX, 
KV4AA,  KZ5BC,  LA6U,  LU3EX,  LU9AX, 
OKIMB,  0N4TQ,  OZIW,  PA0UN,  PA0VB, 
TF3MB,  VK2E0,  VK2GW,  ZLIBY,  ZLIMQ, 
ZS6DW  —  to  mention  a  few.  Each  year  they 
hurl  themselves  into  the  melee  on  one  mode  or 
the  other,  sometimes  on  both.  When  we  raise 
them  there  is  seldom  a  moment  for  even  "HI 
JIM"  or  "PSD  CUAGN  OB,"  the  hustle-bustle 
tempo  being  what  it  is.  But  they  swap  exchanges 
with  thousands  of  us  on  numerous  bands  and 
we  are  grateful  that  they  pop  up  perennially. 
Now  that  the  furor  has  subsided,  the  League 
savs,  on  behalf  of  the  W/VE  contingent,  "MNI 
TNX  OMs  ES  CU  IN  1956."  And  sure-as- 
shooting  we  shall! 

In  line  with  long-estabUshed  policy,  competi- 
tion for  awards  was  confined  to  competitors  in 
each  ARRL  mainland  section  and  in  each  country 
outside  the  U.  S.  and  Canada  from  which 
qualifying  entries  were  received.  Certificates 
of  Performance  will  be  issued  in  these  categories:

QST  for 


thereabouts,    and    with   each    will    go    ARRL's 
congratulations  for  a  job  well  done! 

The  21st  International  DX  Competition, 
however,  was  the  only  recently-scheduled  ARRL 
contest  which  did  not  smash  all  previous  records 
for  participation  (see  Fig.  1).  Despite  vigorous 
advance  promotion  via  lARU  societies,  foreign 
QSL  bureaus,  clubs  and  hundreds  of  prominent 
DXers,  the  success  of  the  contest  appears  to 
depend  principally  upon  the  vagaries  of  sunspot 
numbers  and  the  m.u.f.  This,  of  course,  is 
because  it's  a  DX  activity,  not  a  domestic  QSO 
Party,  and  as  such  it's  particularly  susceptible 
to  the  status  of  the  ether.  Under  the  rules  U.  S. 
and  Canadian  amateurs  must  work  the  270-plu8 
other  items  on  the  ARRL  DXCC  Countries  List. 
It's  the  only  contest  in  amateur  radio  which  pits 
Ws  and  VEs  "against"  the  world,  and  your 
letters  tell  us  that  you  prefer  it  this  way. 

Even  when  the  Kennelly-Heaviside  layer  just 
about  dries  up  and  blows  away,  more  logs  arrive 
from  good  old  Europe  than  from  any  other  con- 
tinent save  North  America.  Reflecting  the  re- 
liability of  the  North  Atlantic  path,  European 
high  scores,  like  statistics  dealing  with  valid 
entries,  testify  to  the  importance  of  ionospheric 
behavior.  In  1949,  for  example,  IS  European 
c.w.  ops  tallied  over  100,000  points,  and  26  did 
it  in  1950.  Their  signals,  with  db.  to  burn,  con- 
sistently blasted  our  eardrums  on  three  or  four 
bands  during  that  banner  era,  an  era  when  the 
Zurich  sunspot  count  hovered  well  over  100.  Alas, 
came  1951  and  the  average  European  score 
plummeted  like  a  helicopter  with  a  jammed  rotor 
—  GW3ZV,  sporting  a  fabulous  combination  of 
gear  and  ability,  was  the  sole  100,000-pointer. 
The  next  three  dreary  years  drew  blanks  but 
results  inched  upward,  and  in  1955  DJIBZ  and 
DLIKB  broke  the  tape  at  138,462  and  102,258 
points  respectively.  As  Europe  goes,  it  seems, 
so  goes  the  DX  Testl^ 

The  C.  W.  Section 

When  records  are  made,  j'ou  can  bet  j'our  r.f. 
gain  control  that  W3BES  will  be  involved.  Mr. 
Mathis  moseyed  over  to  W2SAI  (the  boss  himself 
was  out  of  town)  and,  emplojnng  all  bands  but  1 1 
meters,  achieved  601  QSOs,  a  246  multiplier  and 
443,538  points,  a  brand  new  U.  S.  A.  single- 
operator  high. 

Others  that  reached  the  coveted  6-digit  mark: 

'  There  has  been  no  change  in  the  mathematics  of  scoring, 
but  two  special  factors  modify  postwar  European  compari- 
sons: (1)  The  twofold  liiking  of  W/VE  c.w.  quotas  has  served 
to  swell  QSO  figures  of  DLs,  Gs  and  others  in  the  densely 
populated  countries.  (2)  21  Mc,  available  the  past  three 
contests,  has  already  upped  South  American  and  African 
results  enormously;  Europe- to- W/VE  openings  on  this 
spectrum  portion,  however,  have  been  infrequent  and  tlms 
far  have  affected  European  totals  to  a  negligible  degree. 


VP7NM  dispensed  1939  A-1  exchanges  on  all  bands 
1.8  through  28  Mc.  for  453,725  markers  and  third  high 
non-W  /VE.  Charles,  proprietor  of  the  Bahamas  QSL 
Bureau,  has  142  confirmed  on  the  DXCC  roster.  You 
can  QRO  to  50  w.p.m.  in  his  direction  any  old  time  — 
he's  an  ex-commercial  op.

Herewith  a  couple  of  elaborate  antenna  layouts  that  paid  off  handsomely  in  the  scoring  columns.  Left:  W6YMD's 
beams  and  verticals  form  picturesque  angles  as  they  jut  skyward  at  Pacific  Palisades;  that's  the  base  of  the  3.5-Mc. 
ground  plane  in  the  foreground.  A  quintet  of  Southern  California  DX  Club  brasspounders  utilized  the  whole  shebang 
to  good  avail,  got  a  thumping  363,480  points  ._._._  Right:  Have  a  look  at  the  maze  of  48  elements  comprising

The  'Phone  Section 

In  the  frenzied  battle  of  the  microphones, 
veteran  DXer  WIATE  set  a  staggering  all-time 
high  of  492,184   points.   Chad,   with   his   lavish 


antenna  collection,  scored  everj^place  from  160 
through  10  but  had  his  best  luck  on  20,  where 
435  of  690  QSOs  were  consummated.  He  also 
snared  105  different  countries  for  a  multiplier 
of  238,  was  active  94  hours  out  of  the  possible  96.

These  partook  of  the  verbal  fisticuffs  on  a 
"Winter  Field  Day"  basis  and  fared  well  as 
multioperator  set-ups:  W2SAI  314,880,  W9AVJ

Hawaiian  KH6IJ  shoved  aside  his  electronic 
key,  unshorted  the  modulation  transformer  and 
QSYd  to  the  'phone  segments.  And  before  he 
plopped  into  his  four-poster  on  March  13th, 
Katashi  had  logged  918  contacts,  a  59  multiplier,

The  Clubs 

The  c'ocobolo  gavel  with  the  engraved  silver 
band,  issued  annually  to  the  club  whose  members 
accumulate  the  largest  aggregate  score,  is  dearly 
sought  after  indeed.  Some  groups,  we're  told, 
employ  any  method  short  of  the  cat-o'-nine-tails 
to  effect  a  full  turnout.  Winner  in  1955  was  once 
again  Philadelphia's  Frankford  Radio  Club, 
whose  41  entries  added  up  to  a  brilliant  3.753,930 
points.  In  a  valiant  bid  to  repeat  their  1950 
gavel-winning  drive.  Southern  California  DX 
Club  memlxn's  forged  into  second  position  onl>- 
265,000  points  shy  of  FRC's  total.  The  accom- 
panying tabulation  shows  the  standings  of  the 
36  competing  groups  and  the  calls  of  their  45 
certificate  awardees.

QST  for 


This  neat  arrangement  features  (from  left)  a  p.p. 
8108  rig,  voltage  regulator,  \  FO,  'scope  and  HQ-129X. 
It's  the  property  of  CTISQ,  top  voice  man  for  Europe 
with  46,440  points  and  389  contacts,  47  of  which  came 
about  on  the  allegedly  uninhabitable  40-meter  'phone 
band.  Nice  going,  Humberto!

Timber!  While  he  transmitted  "569  KANSAS"  to 
IIADW  the  first  morning  of  the  c.w.  affair,  WpDAE's 
TO-foot  tower  collapsed.  Undaunted,  Jack  carried  on 
with  makeshift  skyhooks,  got  104,538  points,  tops  for 
his  call  area  and  section.  Dry  those  tears  of  sympathy, 
fellows!  DAE  is  back  in  business  with  an  eflfective  as- 
sortment of  rotaries,  doublets  and  ground  planes.

Of  all  the  areas  around  the  globe,  Asia  has  perhaps 
been  hardest  hit  by  the  ionospheric  doldrums  of  recent 
Tests.  In  1955  Tokyo's  JAICJ,  unimpressed  by  the 
propagation  forecasts,  stacked  485  QSOs  for  50,715 
points,  the  largest  c.w.  total  out  of  the  Far  East  since 
1950.  {Photo  by  JAIGJ^

CONDUCTED  BY  EDWARD  P.  TILTON.  WIHDQ 


IT  is  now  more  than  two  years  since  the  first 
work  of  W4HHK,  W4A0  and  W2UK  in 
sending  2-meter  signals  over  long  paths  by 
meteor  scatter  was  reported  in  these  pages.  In 
this  time  tape  recordings  have  been  played  and 
the  general  subject  discussed  in  nearly  all  parts 
of  the  United  States,  and  the  work  has  attracted 
considerable  favorable  attention  in  scientific 
circles.  Relatively  few  2-meter  men  have  been 
more  than  casuallj'  interested  in  the  new  method 
of  working  v.h.f.  DX,  however,  and  you  can 
count  on  your  fingers  the  number  who  have 
actually  tried  it. 

Yet  W4HHK,  who  was  in  there  first,  has  had 
exciting  success  in  working  2-meter  DX  by  the 
meteor  route.  Two-wav  meteor  communication 
with  New  Jersey  (W2s  UK,  AZL  and  NLY)  and 
Connecticut  (WIHDQ)  was  achieved  last  year, 
the  contacts  with  all  but  W2UK  coming  at  the 
height  of  the  Perseid  meteor  shower  late  August. 
The  Perseids  put  on  a  show  last  August,  peaking 
just  before  the  middle  of  the  month,  so  W4HHK 
was  busy  again  this  summer  drumming  up  some 
schedules  for  exploitation  of  the  opportunity' 
they  would  afford  in  1955. 

New  states  were  the  objective,  and  there  were 
at  least  two  good  prospects.  WIFZJ,  Medfield, 
Mass.,  a  big-antenna  man  from  away  back  as 
W8UKS,  had  been  burning  up  the  2-meter  band 
with  a  high-powered  rig  and  a  64-element  array. 
He  was  an  almost  certain  bet  for  the  first  Tennessee- 
Massachusetts  2-meter  QSO.  Some  sign  of  signals 
had  been  heard  from  W7VMP,  Phoenix,  Ariz.,  in 
the  past,  so  Paul  lined  up  a  series  of  morning 
skeds  with  the  Fenwick  brothers,  too. 

A  test  with  WIFZJ  on  Aug.  12th  produced  the 
first  break.  Using  the  one-minute-each-way 
method  that  had  worked  so  well  under  marginal 
conditions  last  year,  Sam  and  Paul  started  in  at 
0500  CST.  Nothing  was  heard  for  45  minutes, 
but  at  0545  WIFZJ  was  heard  caUing  and 
breaking.  Complete  exchange  of  signal  reports 
and  confirmations  was  accomplished  between 
then  and  0556. 

Then  followed  an  hour  test  sked  with  W7VMP, 
beginning  at  0600  CST.  Several  calls  and  signs 
were  copied,  but  no  complete  exchange  was 
possible  until  the  following  morning.  On  the 
13th,  just  an  hour  was  consumed  in  exchanging 
calls  and  signs,  signal  reports  and  final  confirma- 
tions. One  not  accustomed  to  meteor-scatter  talk 
would  not  think  much  of  the  QSOs  that  are 
achieved  by  this  hit-and-run  approach,  but  the 
fact  remains  that  useful  information  can  be 
e.xchanged  and  positive  identification  established 
b}^  the  meteor-scatter  method.  You  have  to  send 


fairlj'  fast,  on  c.w.,  and  you  have  to  try  again 
and  again,  usually;  but  if  we  judge  a  QSO  by 
whether  or  not  useful  information  can  be  ex- 
changed, then  certainly  these  meteor-scatter  tests 
qualif}'.  Much  more  so  than  some  of  the  exchanges 
that  pass  for  QSOs  in  DX  pile-ups  or  during 
some  of  our  more  hotlj'-contested  operating 
activities  on  lower  frequencies! 

The  W1FZJ-W4HHK  contact  was  good  for 
more  than  1100  miles,  and  the  W7VMP  haul  is 
just  under  1300.  The  limit?  Who  knows,  for  sure? 
What  we  need  is  more  of  this  sort  of  thing,  to 
find  out.  Surely  meteor  scatter  represents  a  way 
to  communicate  with  states  and  over  paths  that 
are  highly  unlikety  to  be  bridged  on  144  Mc.  by 
other  means.  It  put  W4HHK  at  the  top  of  the

states-worked  standings,  with  28,  and  he  is  the 
only  operator  known  to  have  worked  9  call  areas 
on  144  Mc.  Shouldn't  this  be  enough  to  stir  up 
some  interest  on  the  part  of  other  2-meter  DX 
hounds? 

The  possibilities  of  the  6-meter  band  in  this 
department  should  not  be  overlooked,  either.  In 
fact,  the  chance  of  working  long  hauls  under 
otherwise  dead-band  conditions  is  probably  much 
better  on  50  than  on  144  Mc.  The  potentialities 
of  the  50-Mc.  band  will  remain  hardly  more  than 
touched,  so  long  as  the  vast  majority  of  6-meter 
men  operate  with  low  power,  small  antennas,  no 
better  than  mediocre  receivers,  and  voice.  At 
least  a  few  of  us  should  be  going  for  the  limit  in 
all  these  categories,  and  on  c.w.  There  are  some 
surprises  in  store  on  6,  we're  sure,  when  we  give 
it  the  full  try. 

Here  and  There  on  the  V.H.F.  Bands 

The  discussion  of  national  calling  frequencies  for  the 
v.h.f.  bands  (August  QST,  page  57)  has  so  far  brought 
only  three  written  responses.  WIDPO,  Chatham,  Mass., 
and  WN90KB,  who  travels  widely,  are  all  for  the  idea. 
W30TC  likes  the  idea  too,  but  suggests  other  channels 
than  the  50.1-  and  144.6-Mc.  in  the  original  proposal. 

Bob  feels  that  the  6-meter  channel  should  be  in  the 
lower  c.d.  segment,  and  suggests  50.4  Mc,  already  widely 
used  by  nets  in  many  parts  of  the  country.  He  says  that 
members  of  a  fixed-frequency  net  in  Annapolis  have  worked 
18  states  with  both  transmitters  and  receivers  set  on  this 
channel.  For  the  2-meter  band,  W30TC  wants  the  channe 
to  be  in  the  No\'ice  band.  This  also  takes  care  of  the  c.d. 
angle,  but  no  specific  suggestion  has  been  made  as  to  what 
the  frequency  should  be.  Suggestions? 

A  special  frequency  to  monitor  would  be  helpful  to  fellows 
situated  like  XEIGE,  Cuernavaca,  Mexico.  Jeff  has  heard 
DX  signals  in  the  region  j  ust  below  the  50-M(  .  band  many 
times  when  no  amateurs  could  be  heard.  It  is  interesting 


to  note  that  he  has  found  some  resumption  of  the  spring-fall 
50-Mc.  DX  between  Mexico  and  South  America  in  1955, 
after  a  lapse  of  several  years.  XEIGE  heard  harmonics  of 
Latin  American  stations  in  and  near  the  6-meter  band 
several  times  in  March  and  April.  LU8AE  and  LU4BJ 
were  worked  on  March  12th,  his  first  South  American  DX 
on  6  in  4  years. 

Single-hop  contacts  were  made  with  several  W5s  during 
the  May-to-July  Eg  season,  and  on  July  21st,  WICLS, 
WIVNH,  WIHDQ  and  W2MEU  were  worked,  between 
2000  and  2045  CST.  These  are  the  first  XE  —  Wl  and  2 
contacts  since  about  1950,  as  far  as  we  know.  The  50-Mc. 
DX  in  May,  June  and  July  was  better  all  over  the  country 
than  in  several  years  past,  so  it  looks  as  if  we're  on  the 
upgrade  again. 

The  F2-layer  predictions  issued  by  the  Central  Radio 
Propagation  Laboratory  begin  to  look  interesting  again,  too. 
The  charts  for  November  actually  show  a  small  ellipse  of 
50-Mc.  m.u.f.  just  above  Latitude  20  North  in  the  Pacific 
Ocean  area.  KH6s  please  take  not«!  North  Africa,  Southern 
Europe  and  South  America  give  indications  that  50  Mc. 
might  be  open  for  F2  DX  on  the  peak  days  in  both  October 
and  November. 

Here's  a  late  50-Mc.  DX  report.  (Late  because  it  came 
to  your  conductor's  home  address,  and  got  mislaid  in  per- 
sonal papers.  Moral:  Mail  v.h.f.  news  to  ARRL  Head- 
quarters, not  the  home  address  of  WIHDQ!)  VP9AY  made 
what  is  believed  to  have  been  the  first  50-Mc.  contact  from 
Bermuda,  working  W2KNQ,  on  June  23rd.  W2IDZ  and 
W2MEU  were  worked  the  same  night.  On  June  26th,  Max 
(now  WITJZ)  worked  W20HJ,  W8CMS,  W8SVY, 
W8NQD,  W3ZKR  and  W8IIH  between  1935  and  2245 
Bermuda  time.  Signals  were  heard  from  Wl,  4,  6,  7  and  CO. 

VP9BM  writes  that  while  he  is  doing  his  best  to  work 
some  144-Mc.  DX  from  Bermuda  (he's  on  144.35  Mc.)  he  is 
working  on  a  receiver  to  provide  continuous  monitoring 
of  the  f.m.  services  just  below  the  50-Mc.  band,  to  give  him 
tip-offs  on  possible  50-Mc.  DX  to  W. 

In  addition  to  his  5-over-5  that's  120  feet  above  ground 
in  Johnstown,  Pa.,  W3TIF  has  erected  a  4-element  array 
atop  2700-foot  Pleasantville  Mountain  near  by.  Doc  drives 
up  there  and  operates  his  TB8-50,  and  occasionally  a  200- 
watt  24G  amplifier,  in  search  of  contacts  with  Vermont  and 
Rhode  Island,  two  of  the  six  states  he  now  lacks  for  WAS 
on  6. 

Members  of  the  Andrews  Electronics  Association,  whose 
50-Mc.  club  project  was  described  in  August  QST,  operate 
their  Windbag  Net  each  Tuesday  night  at  1900  local  time. 
Frequency  is  50.4  Mc,  and  at  present  10  members  are 
active.  Daily  at  1730  EST  an  informal  get-together  Is  held, 
this  spreading  out  over  Pennsylvania,  New  Jersey  and 
Delaware.  Everyone  is  invited  to  join  in  helping  to  keep  the 
band  hot  through  the  fall  and  winter  months.  This  from 
W3RV  and  W3ZQD,  who  started  the  ball  rolling. 
^-y  Two  more  50-Mc.  men  reached  the  coveted  48-worked 
spot  this  month.  W0DZM,  Minneapolis,  who  had  been  on 
the  hot  seat  with  47  for  years,  finally  caught  up  with 
W7JRG,  Billings,  Mont.,  and  got  the  cards  through  in  time 
to  qualify  for  special  50-Mc.  WAS  Award  No.  13.  W0HVW, 
Pleasant  Hill,  Mo.,  was  the  beneficiary  of  an  expedition 
to  Rulo,  Nebr.,  by  W0QZT.  W0HVW  had  done  this  same 
favor  for  W0INI  a  couple  of  years  ago,  so  it  was  quite 
fitting  that  he  should  make  his  48th  in  a  similar  manner. 
The  Nebraska  activity,  what  little  there  has  been  in  recent 
years,  has  been  beyond  the  reach  of  Missouri  stations,  even 
though  the  two  states  share  a  common  boundary  in  some  50 
miles  of  the  Missouri  River.  The  cards  for  official  confirma- 
tion have  not  yet  been  received  from  W0HVW  as  we  write 
but  he  is  in  line  for  No.  14.  The  W0QXT  expedition  also 
provided  first  Nebraska  contacts  for  W0s  PYK  TOQ  VFF 
VRF  WNU  and  YKI. 


This  array  helped  to  make  the  first  50-Mc.  WAS  by  a 
W2.  The  stacked  4-over-4  at  W2IDZ,  Denville,  N.  J.. 
has  a  12-clement  2-meter  job  in  between  the  6-meter 
bays.  The  2-meter  portion  may  see  some  service  now 
that  Ed  has  nailed  down  the  elusive  48  on  50  Mc.

\".h.f.  men  of  central  New  York  are  invited  to  a  V.H.F. 
Round-up  being  planned  by  the  Syracuse  V.H.F.  Club, 
Saturday,  Oct.  15th.  Starting  time  will  be  2  p.m.  Location: 
I'lank  Taylor's  on  Route  IL  North  Syracuse.  Speaker: 
Art  Koch,  W2R^L\,  well  known  for  his  v.h.f.  and  micro- 
wave gear  in  the  GE  Ham  A'ews  and  QST.  Price:  $2.50. 
including  dinner.  Tickets  and  further  information  from  Joe 
Lando,  K2JIM,  R.D.  1,  East  Syracuse. 

Contacts  over  the  Cascade  Mountains  to  Eastern  Wash- 
ington on  144  Mc,  distances  of  150  to  250  miles,  are  re- 
[lorted  by  W7JIP,  Portland,  Ore.  Higher  power,  big  beams 
(horizontal)  and  better  receivers  are  turning  the  trick. 
\V7JIP's  first  contact  over  this  route  was  with  W7HEA, 
Toppenish,  Wash.  Both  stations  run  about  500  watta. 
Contacts  over  the  Cascades  by  W7LHL,  Seattle,  and  W78 
PVZ  and  UVH  of  Olympia,  130  miles,  were  mentioned  last 
month.  This  work  and  the  contacts  over  the  mountains  to 
Arizona  from  Southern  California  demonstrate  that  there 
is  hardly  any  such  thing  as  an  "impossible"  v.h.f.  path  at 
distances  under  300  miles  or  so.  The  presence  of  high  moun- 
tains in  between  you  and  your  objective  may  actually 
improve  your  chances  of  covering  the  distance.  Under  ideal 
conditions  this  "obstacle  gain"  can  reach  quite  remarkable 
proportions. 

Another  mountainous  path  broken  down  for  the  first 
time:  W7JU,  Boulder  City,  Nev..  finaUy  worked  W7FGG, 
Tucson,  Ariz.,  353  miles,  after  almost  a  year  of  trying. 
VV7JU  runs  100  watta  input,  c.w.,  feeding  a  6-over-6  hori- 
zontal array. 

There  never  has  been  enough  use  of  the  consistently  good 
conditions  that  prevail  on  the  v.h.f  bands  in  the  morning 
hours.  VE3DER,  Toronto,  would  like  it  known  tliat  she 
calls  CQ  to  the  west  each  morning  at  9  on  144  Mc.  If  no 
contact  is  made  she  also  tries  east  and  south. 

Two-meter  mobile  record?  G2HCY  asks  if  his  contact 
with  F9JY,  Cherbourg,  250  miles,  has  been  bettered  by  a 
2-meter  mobile  station  in  this  country.  He  was  actually  in 
motion  at  the  time  contact  was  made,  traveling  about  3 
miles  south  of  his  home  in  Warrington,  Lancashire.  He  has 
also  worked  EI2W  while  mobile,  at  a  distance  of  more 
than  200  miles. 

Those  States-Worked  Boxes 

Every  few  days  someone  writes  in  to  know  how  to  get 
his  call  listed  in  the  50-  or  144-Mc.  states-worked  standings. 
The  answer  is  that  you  just  send  in  your  record.  No  QSLs 
are  needed,  unless  you  are  claiming  WAS;  in  that  case  we 
must  have  proof  in  the  form  of  48  cards.  A  special  hand- 
httered  and  serial-numbered  certificate  is  awarded  to  any- 
one who  makes  the  grade  on  50  Mc.  and  can  prove  it.  We 
may  have  to  get  a  144-Mc.  WAS  award  ready  one  of  these 
days,  at  the  rate  some  of  the  gang  are  going,  but  up  to  now 
we'll  take  your  word  for  the  number  of  states,  call  areas  and 
best  DX  you've  worked  on  2. 

Obviously,  we  can't  list  every  active  v.h.f.  man  in  these 
bo.xes,  so  we  try  to  spot  the  outstanding  achievements  in 
each  call  area.  A  W6  with  3  or  4  states  has  done  an  out- 
standing job,  but  a  Wl  or  W2  with  12  may  never  have 
done  anything  noteworthy.  WIMMN,  in  northern  Ver- 
mont, has  worked  hard  for  his  10  states,  so  he  stays  in,  but 
a  Connecticut  station  with  12  hasn't  done  much  yet,  so  he 
stays  out.  A  rule-of-thumb  check  on  whether  you'll  be 
accepted  for  listing  is  to  see  if  your  record  is  equal  to  or 
better  than  some  fellow  in  your  neighborhood  who  is  already 
listed.  If  it  is,  you're  ehgible.  And  once  you're  in,  be  sure  to 
let  us  know  when  you  move  up  in  any  category. 

Canadian  Provinces  do  not  count  as  states,  and  Canadian 
call  areas  do  not  count  in  the  second  column  of  the  2-meter 
listing.  DX  with  a  Canadian,  Mexican  or  other  non-L^^.S. 
station  can  be  included  for  your  best  DX,  however.  Mobile 
or  portable  contacts  made  while  more  than  25  miles  from 


the  licL'iiscil  lucalnjii  are  not  ac.^,, t-Zi  !■_  :jr  states  claims 
by  the  mobile  operator.  Ship  or  aircraft  stations  are  out,  too. 

We've  received  quite  a  few  requests  to  begin  Usting 
similar  accomplishments  on  220  and  420  Mc.  This  would 
probably  be  done  by  skipping  the  50-  and  144-Mc.  boxes 
occasionally,  and  running  the  box  scores  for  the  higher 
bands.  If  you  want  such  a  listing,  now  is  the  time  to  send 
in  your  records  for  those  bands.  If  we  get  enough  data  we'll 
give  the  higher  bands  a  whirl  now  and  then.  Include  the 
number  of  states  and  call  areas  and  your  best  DX  worked 
on  either  band,  or  both,  in  your  next  report. 

Special  to  Technicians  —  let's  have  your  record  for  50- 
Mc.  work  to  date.  We'U  list  any  respectable  total  of  states 
worked  on  6  by  a  Technician.  Don't  feel  that  you  have  to 
wait  to  catch  up  with  the  fellows  who  have  been  at  it  for 
nearly  10  years! 

OES  Notes 

K2DYC,  Phelps,  N.  Y.  — Operating  on  50.4  nightly,  7  to 
9  P..M.,  looking  for  new  stations.  Western  N.  Y.  activity  on 
6  very  promising. 

K2GAN,  Murray  Hill,  N.  J.  —  Experimenting  with  two- 
tube  compact  transmitter-receiver  for  144-Mc.  local  com- 
nmnication,  presently  using  two  12AT78,  and  operating 
from  90-volt  supply. 

W2UTH,  Victor,  N.  Y.  —  Much  new  activity  on  50  Mc. 
Several  Saturday  morning  skeds  with  WlHDQ,  250  miles, 
show  slightly  better  signals  on  50  than  on  144,  though 
e\-idence  is  inconclusive  as  yet. 

W30TC,  Silver  Spring,  Md.  —  Good  summer  on  50  Mc. 
Worked  7  W6s  on  July  9th,  along  with  stations  in  many 
other  states.  Band  open  more  than  half  the  days  in  July. 
VP9G  worked  July  19th. 

W4FLW,  Dresden,  Tenn.  —  BX  heard  or  worked  19 
different  days  during  July.  Using  converted  Howard  f.m. 
tuner  to  monitor  50-Mc.  band.  As  it  tunes  broadly,  signals 
will  usually  be  heard  if  band  opens  well. 

WoXSJ,  Albuquerque,  N.  Mex.  —  Completed  portable 
transmitter-receirer  for  50  Mc.  Works  from  250-volt  100-ma. 
supply. 

WoRFF,  Albuquerque  —  Off  the  air  due  to  damage  to 
home  and  ham  shack  by  flash  flood.  Antennas  down;  shack 
roof  blown  off,  and  ham  library  and  QSLs  ruined. 

W5SCX,  Ardmore,  Okla.  —  Using  Channel  10  trans- 
mitting antenna,  W5I0W,  Ada,  Okla.,  was  up  more  than  3  S 
units  over  normal  signal.  He  worked  Mississippi,  Kansas 
and  Texas  Panhandle  stations  that  were  inaudible  at 
W5SCX.  The  TV  antenna  is  700  feet  above  ground  level. 

W6CFL,  Los  Angeles,  Calif.  —  Keeping  nightly  sked 
with  K6KHD  on  420  Mc. 

W7JHX,  Port  Orchard,  Wash.  —  Changed  over  to  hori- 
zontal polarization  in  July,  with  varying  results.  Signals 
that  were  reflected  from  mountain  peaks  with  vertical 
polarization  now  seen  weaker  and  more  subject  to  fading 
with  horizontal.  On  the  other  hand,  one  of  the  stations  so 
affected,  VE7JG,  Duncan,  B.  C,  is  able  to  work  Seattle 
stations  regularly  with  horizontal.  These  stations  were  not 
heard  often  with  vertical.  Check  to  be  set  up  with  W7BML, 
Port  Angeles,  Wash.,  who  is  on  the  opposite  side  of  a  6000- 
foot  range  of  mountains,  at  a  distance  of  about  75  miles. 
Signals  over  this  path  have  been  mostly  steady  on  vertical,

F.  E.  HANDY,  WIBDI,  Communications  Mgr. 
GEORGE  HART,  WINJM,  Natl.  Emerg.  Coordinator 
PHIL  SIMMONS,  WIZDP,  Asst.  Comm.  Mgr.,  C.W. 

The  Simulated  Emergency  Test.  By  far  the 
most  important  first-of-season  activity  is  the 
SET.  For  ARRL  Emergency  Coordinators  this 
is  also  their  "annual  roll  call"  time,  and  a  time 
to  extend  the  continuing  invitation  to  all  licensed 
amateurs  to  register  in  the  AREC. 

The  SET  as  explained  more  fully  elsewhere  in 
this  issue  is  a  practical  communications  test 
exercise  based  on  communications  plans  for  the 
locality.  For  those  in  leadership  capacities, 
Emergency  Coordinators  and  Radio  Officers  as 
well  as  AREC  members,  it  is  the  kick-off  for  the 
new  fall-winter  season  of  activity  and  the  proper 
time  to  initiate  the  SET  as  the  first  of  some 
recurrent  planned  tests  to  be  held  during  the 
year.  Responsible  officials  for  the  city  or  area 
and  agencies  to  be  served  should  be  contacted 
by  ECs,  both  to  maintain  friendly  relations  and 
so  that  full  advantage  of  the  exercise  to  improve 
on  past  deployments  of  mobiles  and  facilities, 
or  get  a  statement  or  message  from  officialdom  to 
transmit  as  part  of  the  exercise. 

There  should  be  a  workout  for  emergency- 
powered  equipments,  and  an  attempt  made  to 
build  up  our  capabilities  in  both  size  and  quality 
of  performance  in  connection  with  this  chance  to 
demonstrate  all  our  operative  mobile  gear. 

ARRL's  new  Emergency  Radio  Unit  placards 
are  available  through  ECs  for  temporary  or 
permanent  use  with  cars  or  rigs  and  should  be 
utilized  at  this  time  wherever  justified  by  the 
equipment.  All  AREC  members  with  mobiles 
also  should  ask  ECs  about  the  Official  Mobile 
Unit  pocket  cards  where  mobile  equipment  has 
been  acquired  since  a  previous  AREC  registra- 
tion. This  as  well  as  the  regular  AREC  identifica- 
tion card  will  be  issued  by  ECs  where  warranted. 
Purpose  of  these  forms  is  to  insure  the  individual 
operator  better  public  understanding  of  his 
public  and  amateur  radio  service  functions.  The 
ERU  card  on  one's  car  or  set-with-handles  ad- 
vertises the  public  service  aspects  and  identifies 
amateur  work  as  more  than  a  casual  hobby! 

We  encourage  ECs  to  sign  up  Novice  operators 
in  AREC  (and  newly  licensed  General  Class 
personnel)  as  well  as  amateurs  working  all  bands 
regardless  of  specialized  interest.  The  availabili- 
ties of  WNs  and  Technicians  when  registered 
will  be  considered  by  ECs  and  ROs  to  man  cir- 
cuits and  posts  and  assist  in  other  ways  in  the 
larger  emergency  plans  developed  by  the  whole 
amateur  group.  It  is  essential  to  create  and 
maintain  "one  strong  facility"  through  AREC/ 
RACES  in  connection  with  general  emergency 
work  and  civil  defense  planning.  There  are  not

enough  persons  with  advance  training  and  skill 
to  meet  most  emergencies,  so  every  registrant 
fills  a  real  need  and  should  be  made  a  part  of  the 
team.  We  suggest  that  local  leaders  schedule 
periodic  discussion  periods  and  operating  exer- 
cises through  the  year  and  get  the  help  of  clubs 
in  advancing  know-how  and  in  recruiting  active 
amateurs.  By  critiques  of  the  operations  and 
classes  to  advance  methods  and  procedures, 
strides  in  accuracy  and  speed  of  handling  record 
communications  are  possible.  All  this  helps  each 
individual  make  of  himself  one  of  the  more 
accomplished  rather  than  merely  casual  opera- 
tors in  amateur  circles. 

Results  of  this  test  (the  SET)  are  a  barometer 
scanned  each  _year  indicating  the  over-all  ability 
of  amateurs  to  serve  in  emergencies.  This  test 
therefore  calls  for  every  active  licensee  to  register 
with  his  EC  or  SEC  .  .  .  participating  in  every 
disaster  and  exercise  as  his  circumstances  permit. 
So  be  ready  for  this  test,  whatever  form  your 
local  SET  takes,  on  or  about  October  8th-9th. 
You  as  an  individual,  and  your  community,  and 
the  whole  body  of  amateurs  can  thus  demonstrate 
as  fully  as  possible  our  communications  readiness 
for  either  c.d.  or  natiu-al  disaster  operations. 

Amateurs  Again  Serve  in  Flood  Emergency; 
Report  Your  Part.  Once  again  scores  of  amatevus 
in  and  about  the  stricken  communities  of  several 
states  have  risen  to  support  the  tradition  of  the 
amateur  service  for  providing  stand-by  radio 
communications.  We  have  reason  to  be  proud  of 
the  radio  work  chalked  up  by  amateurs  which 
began  following  the  unprecedented  deluge  deliv- 
ered by  dying  hurricane  Diane.  As  we  write  after 
five  strenuous  days,  operations  are  still  in  prog- 
ress from  Pennsylvania  to  Massachusetts  with 
radio  taking  only  high  priority  traffic  for  those 
points  in  the  Naugatuck  valley  (Conn.)  areas 
where  very  limited  wire  service  has  been  restored. 

Since  WlAW  itself  was  engaged  each  day  we 
had  to  suspend  the  code  practice  periods  dur- 
ing the  peak  of  this  effort;  we  hope  all  parties 
will  understand.  The  National  Emergency  Co- 
ordinator found  himself  in  Pennsylvania,  also 
hard  hit  by  the  storm.  No  few  words  can  ade- 
quately record  the  operating  events  that  have 
transpired  over  such  a  wide  area  in  such  a  short 
space  of  time.  But  the  NEC  will  start  work  on 
the  story  on  return,  when  the  radio  work  itself  is 
completed  and  your  reports  are  in  hand.  We 
want  to  call  on  each  and  every  amateur  par- 
ticipant to  report  his  work,  whether  as  part  of  an 
organized  AREC  or  RACES  facility,  for  gov- 
ernmental units  or  Red  Cross  or  individuals  —

Additional  FCC  Suspensions.  Latest  FCC  ac- 
tions enforcing  indicated  amateur  service  regula- 
tions are  now  reported.  See  page  70  of  March 
'55  QST  and  page  68  of  July  '55  QST  for  suspen- 
sions covering  other  tj^ies  of  violations. 

FCC  ordered  (Augiist  10,  1955)  that  the  amateur  operator 
license  of  Ronald  F.  Ridenour,  Denver,  Colo.,  be  suspended 
for  ninety  days,  that  the  license  be  turned  in  to  the  FCC, 
and  W0CNK  not  be  permitted  to  be  operated  by  any  person 
in  the  90-day  period,  it  appearing  that  the  licensee  on  various 
occasions  during  the  period  from  September  19.52  to  .June 
1955  and  particularly  on  June  4,  1955,  violated  Sections 
12.91  and  12.93  of  FCC  rules  by  engaging  in  the  operation 
of  his  station  after  changing  residence  from  Fort  Dodge, 
Iowa,  to  Denver,  Colo.,  without  first  notifying  the  Commis- 
sion's Field  Office,  Denver,  of  his  intended  portable  opera- 
tion, and  continued  such  radio  operation  for  a  period  ex- 
ceeding four  montlis  without  having  his  amateur  radio 
licenses  modified  to  provide  for  his  change  of  residence,  and 
it  further  appearing,  that  said  licensee  in  this  period  failed  to 
maintain  an  accurate  radio  station  log  and  have  same  avail- 
able for  inspection  by  a  representative  of  FCC,  in  violation 
of  Sec.  12.136  and  12.137  of  FCC  rules. 

FCC  ordered  (.\ugust  17,  1955)  that  the  amateur  operator 
license  of  Jack  A.  Gardiner,  Havre,  Mont.,  be  susi)ended 
for  sixty  days,  that  the  license  be  turned  in  to  FCC,  and 
W7DZF  not  be  permitted  to  be  operated  by  any  person  in 
the  sixty-day  period,  it  appearing  that  the  licensee  on  March 
13,  1955,  operated  on  14,197.9  and  14,198.1  kc,  using  .\-3 
emission  in  violation  of  Section  12.111  of  FCC  rules;  also 
that  he  failed  to  respond  to  FCC  violation  notices  pertaining 
to  the  alleged  improper  operation  which  is  a  violation  of 
Sec.  12.1.55  of  FCC  rules. 

Stuttered    Speech    for    Clearness?    "In    the 

course  of  a  study  of  voice  communication  that 
is  being  made  at  Ohio  State  University.  ...  It 
was  found  that  a  radiotelephone  conversation  is 
much  clearer  if  the  speakers  seem  to  stutter, 
that  is,  if  they  say  'wuh-one,  tuh-two'  instead 
of  the  usual  'one,  two.'  This  method  of  saving 
'wuh-one,  tuh-two'  is  known  as  the  'bounce 
block'  stutter.  .  .  ."  Quote  is  from  the  Nett^ 
York  Times.  K2FG  wonders  if  this  could  lead 
to  'phone  operator  use  of  such  expressions  as 
"Bounce  the  blocks.  Boy  [i.e.,  please  stutter], 
QRM  is  tough"  or  "Gimme  that  ole  double 
stutter,  friend.  The  block  is  bouncing."  A  few 
years  of  this  and  the  only  way  the  XYL  can  get 
through  the  OM's  mental  haze  will  be,  "Nuh- 
now,  duh-dear,  ITi-about  thuh-that  nuh-new 
huh-hat."  With  tough  going  we'll  have  to  stutter 
our  way  thi-ough.  Speaking  of  intelligibilitj',  the 
psychoacoustic  laboratory  at  Harvard  com- 
pleted several  outstanding  studies  during  the 
last  world  war.  Their  conclusions  —  indicating  that 
in  any  phonetic  alphabet,  the  more  sjilables  that 
can  be  used  emphasizing  a  given  character,  the 
better  the  intelligibility  —  agree  firmly  with  the 
above  principle.

DXCC  NOTES 

We  should  like  to  call  attention  to  two  matters  concerning 
DXCC.  A  number  of  DXCC  applicants,  both  for  initial 
applications  and  endorsements,  are  neglecting  to  comply 
with  rule  4  of  the  DXCC  Rules  (copy  upon  request).  Rule  4 
specifically  states  that  a  list  must  be  sent  in  with  all  such 


applications.  Such  a  list  helps  keep  track  of  your  card  mail- 
ings, assists  in  rechecking  at  future  times  and  aids  us  in 
speeding  ser%'ice  to  aU  the  DXCC  gang.  Your  cooperation 
in  complying  with  such  rules  will  be  appreciated. 

At  this  time  we'd  like  to  make  mention  of  a  relatively  new 
U.  S.  Mail  ser\ice  known  as  certified  mail.  As  far  as  safe 
mail  deliverj'  is  concerned,  this  new  ser\ice  does  exactly  the 
same  thing  as  registered  mail,  but  at  less  than  half  the  cost 
of  registered  mail.  Incidentally,  registered-mail  fees  have 
gone  up  to  40  cents  for  North  and  South  America  and  55 
cents  for  all  other  parts  of  the  World  (4  and  5  IRCs  respec- 
tively). Regrettably,  the  certified  mail  ser\ice  is  applicable 
only  in  the  U.  S.  and  possessions.

In  most  AREC  organizations,  the  EC  has  enough  to  do 
in  just  organizing  and  promoting.  Yet,  we  here  at  ARRL  are 
constantly  hounding  iiini  to  report:  report  this,  report  that, 
give  us  figures  on  the  other  thing,  and  so  on.  Along  with  this, 
we  say  we'd  rather  have  an  EC  who  does  things  but  reports 
nothing  than  one  who  does  nothing  and  reports  just  that. 

The  value  of  statistical  reports  is  tremendous,  and  yet 
it's  a  big  chore  for  the  ECs  to  compile  and  submit  them  — 
especially  for  some  ECs  who  are  super-active  when  it  comes 
to  operations  but  not  the  slightest  interested  in  statistics. 
We've  done  some  thinking  about  this  and  would  like  to  make 
a  suggestion. 

How  about  an  AREC  reporter?  Our  organizational  stand- 
ards provide  for  Assistant  ECs  to  take  on  specialized  depart- 
ments of  the  work,  especially  in  large  organizations.  Why 
not  designate  one  of  your  members  who  is  statistically  in- 
clined, or  handy  with  the  pen,  as  Assistant  EC  in  charge  of 
reports  and  publicity?  It  could  be  a  big  job,  and  a  most 
important  one.  He  would  need  to  know  what's  going  on  in 
the  AREC  organization,  how  RACES  is  progressing  locally; 
he  would  want  statistics  on  all  sub-groups;  he  would  need 
contact  with  local  newspapers,  radio  and  TV  stations  to 
give  the  group's  efforts  publicity;  and  his  would  be  the  job 
of  writing  up  regular  EC  reports  for  the  EC's  signature  to 
go  to  the  SEC  or  headquarters  and  any  writing  or  reporting 
to  be  done  for  QST  or  other  publications. 

An  Assistant  EC  serving  as  "AREC  Reporter"  would  be 
most  valuable  in  the  larger  organizations,  of  course  — 
such  as  those  in  large  cities.  There,  unlike  the  small  com- 
inunity,  the  EC  cannot  do  all  the  work.  He  has  to  delegate  a 
lot  of  functions  and  be  pretty  inuch  an  overseer  of  work 
being  done  rather  than  the  one  who  does  the  work.  To  an 
active  amateur,  overseeing  is  a  harder  job  than  doing  the 
work  himself;  that's  why  many  of  our  ECs  are  overworked 
and  quickly  burn  themselves  out.  An  AREC  statistician  or 
general  reporter  could  do  much  to  take  some  of  the  hated 
statistical  and  reporting  burden  off  his  shoulders.  Has  any- 
one tried  this? 

Supplementary  "Operation  Alert"  reports: 
In  Omaha,  two  separate  operations  were  conducted. 
One  was  to  provide  communication  between  c.d.  Medical 
and  18  first  aid  stations.  The  other  was  to  provide  communi- 
cations between  county  and  state  civil  defense  headquarters. 
The  former  was  done  on  ten  meters,  with  mobiles  reporting 
in  from  first  aid  stations.  The  latter  was  done  on  75,  and  a 
relay  established  between  county  c.d.  headquarters  and  2- 
meter  control.  Thirteen  mobiles  were  operated  and  18  otlier 
amateurs  participated. 


W8HZA  reports  that  the  West  Virginia  Net  (WVN)  in 
cooperation  with  the  West  Virginia  Phone  Net  was  active 
in  "Operation  alert"  from  1600  to  22.30  on  June  15th.  Ten 
meter  links  maintained  contact  between  state  c.d.  head- 
quarters (W8QHG),  the  'phone  message  center  (W8CLX) 
and  the  c.w.  message  center  (W8HZA/8). 

Oregon  SEC  W7WAT  reports  participation  in  his  section. 
In  Portland,  W7VS  operated  from  c.d.  headquarters  under 
the  direction  of  W7KY  on  3995  kc.  In  Medford,  participa- 
tion was  on  a  limited  basis  by  members  of  the  Rogue  Valley 
Amateur  Radio  Club,  including  W7s  HLF  (RO)  QMK  ULR 
OFS  and  LYR. 

On  April  25th  the  Red  Cross  alerted  the  AREC  in  Hamil- 
ton, Ont.,  to  render  service  in  connection  with  a  flood  and 
high  waves  in  the  Crescent  Beach  area  of  Lake  Ontario.  Two 
mobiles  were  put  into  action  at  the  Beach,  and  the  Red 
Cross  official  was  transported  to  the  beach.  Four  mobiles 
and  a  control  station  saw  action  in  this  emergency. 

—  VESKM,  SEC  Ontario 


On  July  23rd  a  soldier  drowned  near  Great  Falls,  Mont., 
in  the  Missouri  River.  Amateurs  from  Great  Falls  were 
called  upon  to  assist  in  rendering  communications  between 
the  scene  and  the  Great  Falls  Army  Air  Base.  W7PCZ/m 
operated  at  the  scene  while  W7TSG  and  W7KUH  handled 
other  necessary  communications  contacts. 

—  W7KUH,  SEC  Montana 


W70KM  was  able  to  perform  an  emergency  service  on  the 
"Seven  Devils  Road"  (U.  S.  Route  101)  between  Coos  Bay 
and  Bandon,  Ore.,  on  July  31.  Spotting  a  car  off  the  road 
on  the  brush  on  one  of  the  many  bad  turns  in  the  road,  he 
stopped  his  car  and  investigated.  The  stalled  vehicle  was 
from  British  Columbia  and  was  teetering  perilously  on  the 
edge  of  a  canyon,  occupants  still  inside  and  afraid  to  move. 
While  W70KM  contrived  to  steady  the  teetering  car,  the 
British  Columbia  couple  climbed  out  safely.  Then  he  con- 
tacted W7VPF  from  his  car  and  had  him  summon  a  tow 
car,  which  arrived  45  minutes  later  and  pulled  the  en- 
dangered automobile  to  safety. —  W7QKU,  PAM  Oregon. 

We  want  to  enter  herewith  a  few  words  of  praise  for  the 
Alabama  Section  emergency  organization.  There  has  just 
recently  come  to  our  desk  an  eighteen-page  manual  of 
"Instructions  for  Members  of  AEN  CW  and  Phone  Nets," 
issued  and  approved  jointly  by  the  Section  RM  (W4KIX), 
the  Section  PAM  (W4WOG),  the  SEC  (W4TKL)  and  the 
SCM  (W4MI).  Although  the  cover  realistically  states  that 
the  manual  covers  only  the  "barest  essentials,"  it  is  one  of 
the  most  complete  and  comprehensive  section  net  operating 
manuals  and  directives  we  have  seen.  Other  sections  might 
well  take  a  cue  from  Alabama  on  their  fine  net  organization. 

Fifteen  SECs  reported  June  activities,  representing  5195 
.\REC  members.  Two  reports  did  not  include  figures  on 
AREC  membership.  Reporting  sections:  Minn.,  Wash., 
Tenn.,  West  N.  Y.,  NYC-LI,  Georgia,  Kentucky,  San 
Joaquin  Valley,  Louisiana,  Wis.,  Colo.,  S.  Dak.,  Los  Angeles, 


Here  is  the  Mobile  Squad  of  Civil  Defense,  Saline  County,  Salina,  Kans.  Most  of  them  are  members  of  the 
Central  Kansas  Radio  Club.  All  members  of  the  mobile  squad  are  police  commissioned  and  carry  out  their 
duties  with  the  full  support  of  the  police.  A  great  deal  of  commendable  work  has  been  done  in  this  manner.

QST  for 


The  Western  Illinois  Radio  Club  of  Quincy  purchased 
this  bus  and  turned  it  over  to  the  city  of  Quincy  to  be 
made  into  a  communications  control  center.  The  city 
purchased  some  equipment  for  it,  and  club  members  did 
most  of  the  work  installing  it.  It  is  intended  primarily 
for  civil  defense  use  and  contains  several  transmitters 
and  receivers,  a  {;as-driven  generator  and  a  public  ad- 
dress svstem. 


Mont.,  Ore.  This  June's  results  exceed  those  of  June  a  year 
ago  and  two  years  ago,  both  in  number  of  reports  and  num- 
ber of  AREC  members  represented.  The  mid-year  record 
thus  shows  a  gratifying,  if  not  considerable,  increase  over 
that  of  last  year.  For  example,  at  midyear  1954  we  had 
reports  from  21  different  sections;  this  year  we  have  26 
different  ones.  At  mid-year  1954  we  had  a  total  of  77  reports 
on  file;  this  year  we  have  98.  The  record  even  compares 
favorably  with  our  good  1953  record,  but  does  not  yet  ex- 
ceed it  in  all  particulars.  It  would  be  easy  to  do  so  if  more  of 
you  SECs  would  drop  us  a  report  on  Form  8  each  month. 
The  following  sections  have  a  100%  reporting  record  so 
far  this  year:  Minnesota,  Western  N.  Y.,  NYC-LI,  San 
Joaquin  Valley,  Wisconsin,  South  Dakota.  These  have 
missed  only  one  report:  Washington,  Tennessee,  Georgia, 
Eastern  Florida,  Los  .Angeles,  Oregon. 

RACES  News 

We   have  just   received   from   FCDA   a   comprehensive 
listing  of  states  and  local  areas  now  operating  under  RACES 
plans.  Although  it  will  take  up  quite  a 
lot  of  room,  we  think  it  is  worth  repro- 
ducing here.  The  following  states  are  now 
operating    under    state    R.A.CES    |)lans: 
.\labaina,  California,  Colorado,  Connecti- 
cut, Delaware,  Florida,  Georgia,  Idaho, 
Illinois,    Kansas,    Louisiana,    Maryland,

Carolina,  Ohio.  Oklahoma,  Oregon,   Pennsylvania,  Rhode 
Island,   Tennessee,   Vermont,  Virginia,   Washington,   West 
Virginia,  Wisconsin.  That  makes  34  states  under  RACES, 
leaving   14   who  have  not   yet  submitted   R.\CES   plans; 
however,  of  these  14,  six  have  local  RACES  authorizations

BPL  medallions  (see  Aug.  1954  QST,  p.  64)  have  been 
awarded  to  the  following  amateurs  since  last  month's 
listing:  K4AKP,  W4DDY,  K4WBG,  W5DTA/5, 
W5KPB.  W9YWL. 

The  BPL  is  open  to  all  amateurs  in  the  United  States, 
Canada,  Cuba,  and  U.  S.  possessions  who  report  to  their 
SCM  a  message  total  of  500  or  more,  or  100  or  more  orig- 
inatlons-plus-deliveries  for  any  calendar  month.  All  mes- 
sages must  be  handled  on  amateur  frequencies,  within 
48  hours  of  receipt,  In  standard  ARRL  form. 


TRAFFIC  TOPICS 

It  is  entirely  inevitable  that  we  continue  to  regard  traffic 
activity  on  the  amateur  bands  in  terms  of  "seasons"  rather 
than  calendar  years.  Not  only  is  this  a  result  of  habit,  be- 
cause we've  always  done  it  that  way  and  years  ago  nearly 
all  traffic  activity  was  suspended  in  May  until  October,  but 
also  of  the  necessity  of  taking  into  account  the  fact  that 
most  traffic  men  handle  traffic  because  they  enjoy  it  —  and 
they  don't  enjoy  it  in  the  summer,  with  heat,  insects,  QRN 
and  diversions  occasioned  by  vacations  and  other  invitations 
to  the  great  out-of-doors. 

Since  the  advent  of  NTS,  however,  and  the  tendency  in 
other  traffic  circles  as  well  to  keep  the  traffic  moving  all 
year  around,  the  aspect  of  "seasons"  of  traffic  handling  has 
been  less  noticeable.  Oh,  activity  still  drops  off  in  summer- 
time, and  network  organization  goes  all  to  pot  when  people 
start  legal  clock-changing,  but  you'll  notice  that  the  BPL 
is  far  larger  by  comparison  during  the  summer  months  than 
it  used  to  be,  say,  in  1936.  For  example,  in  December  of 
1935  we  had  109  BPLs,  but  the  following  August  only  nine 
—  this,  mind  you,  during  the  lush  traffic  years  when  traffic 
handling  was  described  (by  Clinton  B.  DeSoto)  as  the 
"major  activity"  in  amateur  radio.  Compare  this  with  the 
BPL  total  of  114  in  December  of  1953  and  85  in  August  of 
1954.  Our  summertime  traffic  activity,  these  days,  is  equal 
to  some  of  the  lower-yielding  winter  traffic  months.

QST  for 


This  is  as  it  should  be.  If  we  are  going  to  have  a  function- 
ing  traffic  organization,  it  should  function  all  year  around. 
If  training  is  ene  of  the  most  important  objectives  in  our 
traffic  work  (and  we  think  it  is),  training  in  handling  traffic 
under  unfavorable  conditions  is  one  of  the  best  kinds,  if  not 
Ihe  best  kind.  Why?  Because  most  training  is  conducted  un- 
der favorable  conditions,  causing  almost  complete  break- 
down when  the  trainee  is  faced  with  difficulties. 

We  have  no  quarrel  with  "fair  weather"  traffic  men. 
In  fact,  we're  miglity  glad  to  have  them  working  in  the  sys- 
tem during  the  good  radio  months.  All  we're  saying  is  that 
the  boys  who  stick  with  it  all  summer  are  getting  the  great- 
est benefit  and  doing  the  greatest  good.  And  now  that  the 
fall  operating  season  is  on  us  again,  let's  make  this  the 
greatest  traffic  year  yet. 

HAVE  YOU  REGISTERED  YOUR  NET?  If  not, 
better  do  it  if  you  want  it  in  the  annual  Net  Directory. 
Deadline  for  November  QST  listing  was  September  15;  for 
January  QST  listing,  November  15.  For  the  cross-indexed 
net  directory,  December  1.  See  Traffic  Topics  in  September 
QST  for  details  on  how  to  register. 


Traffic  nets  will  have  a  part  to  play  in  the  Simulated 
Emergency  Test,  October  8th-9th.  This  is  an  ideal  activity 
with  which  to  pry  the  lid  oflf  the  so-called  fall  operating  sea- 
son. See  complete  announcement  elsewhere  in  this  issue  of 
QST. 

The  First  Call  Area  Section  of  the  Transcontinental 
Phone  Net  registered  614  message  counts  with  14  stations 
participating  in  July.  During  June,  the  message  total  was 
400  by  8  stations.  The  Second  Call  Area  Section  reports  608 
messages  by  12  stations  in  July,  786  messages  by  12  stations 
in  June.  This  info  by  WILYL. 

National  Traffic  System.  As  of  this  writing,  the  Eastern 
Area  Net  of  NTS  can  handle  traffic  addressed  to  APO  New 
York  City.  This  is  handled  by  a  corps  of  stations  organized 
by  W2JOA  who  reiiort  into  EAN  for  that  purpose  each  night. 
The  traffic  is  handled  via  MARS  circuits,  not  by  amateur 
radio.  Stations  participating  are  W2JOA,  K2JEB,  K2AEQ 
and  W3WG.  If  you  have  traffic  for  APO  New  York,  it  can 
be  routed  to  EAN  through  normal  NTS  channels. 

Traffic  for  APO  San  Francisco  (or  other  Pacific  points)  is 
an  assignment  of  the  Sixth  Regional  Net  and  should  be 
routed  through  PAN  to  RN6.  APO  Seattle  is  similarly 
handled  by  RN7. 

Of  course  we  can't  guarantee  that  these  routings  won't 
be  changed  by  the  time  you  read  this!

It  appears  that  one  of  the  hardest  things  for  net  managers 
to  do  is  get  their  reports  in  here  on  time.  This  isn't  always 
their  fault,  after  all,  they  have  to  get  QNS  reports  from 
NCS  before  they  can  make  out  a  report,  simple  as  it  is  after 
that.  So  this  is  a  plea  to  NTS  Net  Control  Stations  at  all 
levels:  report  to  your  net  manager  promptly  after  you  control 
a  net  session,  whether  you  are  the  regular  control  or  not. 
Failure  to  do  so  results  in  a  delayed  report  (which  may  then 
miss  its  proper  issue  of  QST),  or  an  incomplete  report  which 
prevents  us  from  indicating  the  true  status  of  NTS.  NCS: 
report  to  net  manager  promptly!  Net  Managers:  Get  reports 
into  headquarters  not  later  than  the  fifteenth  of  each  month! 

Despite  the  "summer  slump,"  only  two  regional  nets 
and  one  area  net  failed  to  report,  and  fifteen  section-level 
nets  reported.  Traffic  is  low,  but  organizational  morale  is 
high.  RN5  reports  a  sharp  decrease  in  traffic  with  cessation 
of  traffic  from  MARS  sources;  K4AKP  has  been  most  con- 
sistent station  during  July.  RN6  certificates  have  been 
awarded  to  K6GID,  W6TTX,  and  K6EVM.  July  RN7 
representation  has  been  nil  from  Wyoming,  Montana, 
Saskatchewan,  Alberta  and  Alaska.  W4KKW  submits  his 
first  report  as  9RN  manager.  W0KLG  submitted  the  July 
TEN  report  for  W0DQL.  VE3GI  reports  that  Maritime 
representation  is  badly  needed  on  TRN. 

In  TCC,  W0KQD  will  take  over  the  TCC  Pacific  Area 
directorship  being  vacated  by  W6HC  at  the  end  of  Septem- 
ber. W9JUJ  will  continue  with  the  Central  Area  directorship 
and  W8UPB  with  Eastern  Area.  The  present  roster,  accord-

You  are  hereby  notified  that  an  election  for  Section  Com-

Section.  This  notice  supersedes  previous  notices. 

Nominating  petitions  are  solicited.  The  signatures  of  five 
or  more  ARRL  full  members  of  the  Section  concerned,  in 
good  standing,  are  required  on  each  petition.  No  member 
shall  sign  more  than  one  petition. 

Each  candidate  for  Section  Communications  Manager 
must  have  been  a  licensed  amateur  for  at  least  two  years 
and  similarly  a  fuU  member  of  the  League  for  at  least  one 
continuous  year  immediately  prior  to  his  nomination. 

Petitions  must  be  in  West  Hartford,  Conn.,  on  or  before 
noon  on  the  closing  dates  specified.  In  cases  where  no  valid 
nominating  petitions  were  received  in  response  to  previous 
notices,  the  closing  dates  are  set  ahead  to  the  dates  given 
herewith.  The  complete  name,  address,  and  station  call  of 
the  candidate  should  be  included  with  the  petition.  It  is

tained, since  on  checking  names  against  Headquarters  files,

petition  may  be  found  invalid  by  reason  of  expiring  mem- 
berships, indiWdual  signers  uncertain  or  ignorant  of  their

After  making  380  c.w.  QSOs  at  W1.\W,  statistics-minded 
WIWPR  sat  down  and  did  some  figuring  on  the  distribution 
of  appointments.  There  were  273  stations  worked  once,  78 
two-banders,  14  three-banders,  and  one  four-bander.  Here's 
the  way  the  273  different  broke  down:  ORS  138,  OO  47,  EC 
24,  RM  18,  OBS  13,  OPS  7,  Asst.  Director  5,  SCM  5. 
Director  4,  PAM  3,  OES  2,  Headquarters  2,  Vice-Director 
2,  QSL  Manager  2,  SEC  1.  Since  those  holding  more  than 
one  appointment  can  pick  any  one  of  several  to  identify 
themselves,  the  figures  must  be  taken  with  a  pinch  of  salt. 
Apparently,  however,  in  a  c.w.  CD  Party  more  than  half 
your  contacts  will  say  "  HR  ORS."

About  "S''  Meters 

^^E  ARE  all  familiar  with  the  "S"  meter  calibration  on  communications  receivers  and  know 
that  indications  on  that  meter  present  a  measure  as  to  the  strength  of  signal  being  received 
in  comparison  with  other  signals.  This  is  the  basic  purpose  of  the  meter  and  in  that  func- 
tion it  serves  well,  but  what  about  the  calibration  of  that  meter  as  far  as  its  being  a  standard 
is  concerned? 

/ALTHOUGH  there  are  occasional  departures,  the  standard  S-unit  interval  has  come  to  be 
established  at  about  6  db.  If  you  dig  into  the  subject  a  little  further,  you  will  come  up  with 
the  fact  that  a  signal  indicating  S-9  on  one  receiver  will  not  necessarily  be  S-9  on  another. 

/HE  "S"  meter  readings  can  be  quite  different  even  on  identical  receivers  run  off  the  same 
production  line  unless  some  special  care  is  employed  during  manufacture.  Actually,  "S" 
meter  readings  between  different  makes  of  receivers  are  about  as  standard  as  a  yard  deter- 
mined by  the  stride  of  a  six  foot  man  and  a  four  foot  man. 

Basically  an  "S"  meter  is  a  current  reading  device  connected  in  some  point  of  the  receiver 
circuit  controlled  by  AVC  where  a  change  in  received  signal  strength  will  cause  a  change  in 
current  flow.  Whatever  will  affect  that  circuit  will  also  affect  the  current  readings. 

Ti^E  AT  Hallicrafters  employ  a  0-5  MA  meter  connected  in  series  with  the  B+to  an  RF  or 
IF  tube.  This  is  a  very  effective  circuit  which  will  iminediately  indicate  changes  in  plate 
current  caused  by  a  variation  of  AVC  voltage  at  the  grid  of  the  tube  according  to  the  strength 
of  the  signal  being  received. 

/  F  A  conventional  meter  is  used  in  this  circuit,  the  meter  calibrations  would  be  somewhat 
confusing  as  they  would  be  backwards.  To  avoid  complex  bridge  network  circuitry  we  simply 
purchase  our  "S"  meter  movements  with  the  springs  reversed,  so  with  no  current  through 
the  meter,  the  pointer  rests  at  the  right  hand  side  of  the  scale. 

„fTLTHOUGH  all  tube  manufacturers  fabricate  tubes  to  certain  industry  standards,  there  still 
will  be  differences  in  the  actual  operating  characteristics  of  each  tube.  Tolerances  of  tubes 
and  other  parts  in  the  communications  receiver  may  also  be  affected  by  aging  and  other 
conditions  to  which  the  receiver  is  subjected  during  its  lifetime.  Therefore,  the  "S"  meter 
readings  will  be  affected  also. 

/t  is  obvious  that  with  a  poor  antenna  the  signal  strength  on  a  given  signal  will  be  less  than 
the  same  signal  on  a  better  antenna.  Hence,  an  "S"  meter  report  should  be  considered  in 
view  of  the  antenna  used.  To  provide  some  standardization,  we  at  Hallicrafters  have  as- 
sumed that  a  50-microvolt  signal  at  the  antenna  posts  on  the  80  meter  band  is  an  S-9  signal. 
To  afford  more  versatility  to  the  meter,  on  our  large  sets  we  also  provide  a  second  scale 
calibrated  in  microvolts.  On  certain  larger  receivers  it  is  possible  to  hold  this  calibration 
fairly  close  throughout  the  tuning  range.  However,  production  variations  in  tube  Gm  pre- 
clude extreme  accuracy  in  calibration  and,  therefore,  don't  consider  your  receiver  as  a 
Standard  Field  Strength  Meter. 

/Tging  of  the  receiver  and  resultant  changes  in  component  values  and  operating  character- 
istics may  affect  the  original  factory  set-up  of  the  "S"  meter,  thereby  making  it  impractical 
to  use  an  "S"  meter  as  a  standard  of  measurement.  But  even  though  the  "S"  meter  cannot 
be  used  as  a  measurement  standard  unless  calibrated  frequently  from  a  local  standard 
signal  source,  it  is  still  an  invaluable  aid  and  helpful  tool  in  the  operation  of  an  amateur 
radio  station.

Here  .  .  .for  the  first  time  ...  is  a  truly  selective 
bandpass  type  adapter  for  briiifiing  the  perform- 
ance of  yesterday's  receivers  up  to  the  requirements

A  PAIR   OF  EIM 

the  easy,  modern  approach 
to  a  compact  one-kilowatt  CW  and  SSB  rig 


You'd  be  amazed  how  easy  it  is  to  build  a  one- 
kilowatt  rig  using  Eimac  4X250B  radial-beom  power 
tetrodes.  Each  of  these  bantam  tubes  handles  500 
watts  input  with  only  2000  volts  on  the  plate. 
A  pair  in  the  final  amplifier  provides  a  kilowatt 
with  the  power  supply  and  transmitter  combined 
taking  only  a  fraction  of  the  space  required  for  an 
old-fashioned   kilowatt  rack. 

The  straight  forward  modern  approach  afforded  by 
4X250B's  allows  simple  circuit  design.  Driving  power 
is  so  low  that  annoying  TVI-producing  harmonics 
generated  in  the  driver  stages  are  minimized.  Low 
feedback  capacitance  makes  stabilization  of  the 
amplifier  stage  easy. 

The  versatile  4X250B  can  supplant  the  famous 
4X1 50A,  and  it  offers  the  advantages  of  easier 
cooling  and  higher  power.  No  forced-air  cooling  is 
required  during  stand-by  periods  if  convection  air 
is  provided   properly. 

For  further  information  on  the  new  4X250B,  contact 
our  Amateur  Service  Bureau  or  visit  your  Eimac 
distributor.

Mallorv  #1600  Series  Rotary  Switches,  better  known  as  "Hamband  switches  were  designed 
e  pec  I  U  for  coil  switching  in  high  frequency  transmitter  service.  How^ever,  the  heavy,  wade- 
Zccd  contacts,  high  quaUty  ceramic  insulation,  and  positive  indexing  which  make  these  switches 
.o  desirable  for  use^n  transmitter  plate  circuits,  also,  give  them  exceptional  capability  for  many 
other  switching  functions. 

For  example,  the  diagram  above  shows  how  a  #164C  (4  section  "Hamband"  switch),  connected  as 
a  crcuit  changer,  permits  operation  of  two  separate  RF  chassis  from  common  power  supplies  and 
a  sin.  e  modulator  VHF  operators  in  particular,  who  operate  separate  rigs  above  and  be  ow  50 
m'Icvcres  w  11  recognize  the  economy  and  convenience  this  arrangement  adds  to  such  a  s  a  ion. 
With  contact  carrying  abilitv  of  several  hundred  milliamperes  and  with  1000  volt  insulation, 
this  switch  is  entirely  adequate  for  transmitter  powers  up  to  100  watts. 

Tlie  circuit  shown  was  devised  bv  a  dyed-in-the-wool  VHF  man  to  permit  the  addition  of  a  low 
frequencv  RF  unit  to  his  existing  VHF  transmitter,  and  still  use  only  the  common  power  supplies 
and  si  ie  modulator  shown.  However,  there  is  no  reason  why  a  dyed-in-the-woo  lou^^  frequenry 
man  coudnt  make  the  change  the  other  way  'round,  and  let  the  #164C  switch  help  him  explore 
The  polibilities  of  VHF  operation  with  a  minimum  expenditure  of  funds  for  new  gear. 
When  usin-  the  #164C  for  this  apphcation,  the  usual  high  voltage  wiring  precautions  should  be 
Iserved  e';-en  though  the  exact  circuit  arrangement  may  be  modified  to  suit  individual  require- 
ments The  one  shovs^i  has  the  indicator-lamp  circuit  located  adjacent  to  the  panel,  the  low  voltage 
iTplv  next  then  the  high  voltage,  and  last  the  modulator  transformer  shorting  section  for  CW 
ope  a  ion  The  phvsical  location'^of  the  switch  in  relation  to  the  power  supplies  modulator  and 
RFchas  is  i  not  important,  and  mav  be  placed  for  maximum  convenience.  The  circuit  shown 
has  the  switch  located  within  the  modulator  housing.  Separate  input  and  output  sockets  for  each 
piece  of  equipment  are  mounted  at  the  rear  of  the  modulator. 

The  convenience  and  efficiencv  added  by  this  circuit  has  been  reported  by  its  user  to  be  most 
Satisfying!  Why  don't  you  investigate  the  money  saving  possibilities  Mallory  rotary  switches  offer? 
Your  Mallory  distributor  will  be  glad  to  help  you  select  the  right  one.

"Designed  for  the  Ham 

Who  Demands  the  Best" 

Rod.o  Spedalfies,  Inc.  proudly  presents  the  greatest  devel- 
opment in  rotary  antennas.  This  is  the  result  of  20  years 
of  development  and  research  by  S.  E.  "Dick"  Adcock  of 
Miami,  Florida  who  has  designed  and  perfected  this  most 
revolutionary  antenna  ever  to  be  used  by  the  Amateur.  The 
ultimate  in  engineering  design  and  the  finest  of  materials  are 
combined  with  precision  workmanship  to  create  a  product 
unexcelled  in  the  antenna  field. 

The  extremely  low  vertical  angle  of  radiation  will  provide 
the  BEST  in  DX  reception.  Extraordinary  front  to  back  ratio 
guarantees  minimum  QRM.  Exceptionally  high  forward  gain 
assures  outstanding  reports.  On  the  air  tests  by  W4GL  over 
a  period  of  many  years  have  proved  that  this  all  driven  array 
has  outperformed  any  parasitic  antenna  as  to  forward  gain, 
front  to  back  ratio  and  a  desirable  radiation  angle.  W4GL'S 
outstanding  signal  using  the  all  driven  array  has  been  heard 
the  world  over  with  excellent  reports.

NORTHWESTERN  DIVISION 

ALASKA  — SCM,  Dave  A.  Fulton,  KL7AGU  —  The 
1955  All-Alaska  Ham  Convention  was  a  great  success.  The 
Hamfest  was  sponsored  by  the  Anchorage  Amateur  Radio 
Club  and  was  held  in  Anchorage  this  year.  There  were  120 
licensed  hams  registered  and  119  attended  the  banquet. 
AOT  and  ANG  shared  honors  for  the  best  mobiles.  BJW 
won  the  hidden  transmitter  hunt,  BK  the  ragchewers  con- 
test, and  CC  walked  away  with  the  c.w.  honors  (35  w.p.m. 
with  a  stick).  The  highlight  of  the  affair  was  a  visit  by 
Northwestern  Division  Director  R.  Rex  Roberts,  W7CPY. 
Rex  visited  Fairbanks  before  attending  the  hamfest  in 
Anchorage  and  stopped  at  Juneau  on  his  way  back  home. 
This  is  the  first  time  that  an  ARRL  official  has  ever  visited 
the  territory  and  we  certainly  hope  it  won't  be  the  last.  If 
Rex  enjoyed  it  here  half  as  much  as  we  enjoyed  having  him, 
we  know  it  will  not  be  the  last  time  for  him.

MONTANA  —  SCM,  Leslie  E.  Crouter,  W7CT  —  Capt. 
Albert  White,  ZKV,  of  the  Great  Falls  Army  Air  Force 
Base,  felt  that  their  l.f.  communications  channels  could  be 
jammed  but  that  they  could  get  a  fix  to  a  particular  location. 
ZKV  thought  that  amateur  radio  (mobile  with  loop  anten- 
nas) in  those  localities  when  alerted  and  with  arrangements 
with  the  local  sheriff  could  track  down  and  make  an  arrest 
of  the  jamming  station.  The  Great  Falls  Emergency  Corps 
responded,  as  reported  by  net  control  and  EC  DSS.  TLA, 
mobile,  assisted  by  TSG,  was  the  hidden  transmitter,  with 
19  hams  and  17  stations  taking  part,  of  which  9  were  mobile 
doing  the  himting.  All  used  loop  antennas  to  look  for  the 
hidden  rig  on  3910  kc,  with  GFT  the  only  one  using  an  FS 
meter.  GFT  found  the  station  in  about  ten  minutes.  Capt. 
White  wants  something  like  this  in  all  of  four  or  five  of  these 
northern  states  but  wanted  it  tried  out  to  gain  experience 
to  help  in  organizing.  The  Old  Faithful  Radio  Club  oper- 
ated under  the  club  call,  ZOD,  at  the  Park"  County  Fair. 
YPN  lias  been  in  the  hospital  and  is  now  taking  it  easy. 
VGY  is  finishing  a  new  150- watt  rig.  LPL  spent  his  vacation 
in  YeUowstone  Park.  On  July  3rd  TPE,  Wolf  Point;  OYP, 
Wolf  Point;  TNJ,  Glasgow;  and  SEW,  Malta,  set  up  com-

READ  THIS  AMAZING  LETTER:  How  an  inexpensive  ¥\}LL 
SIZE  Gotliam  Rotary  Beam  made  it  possible  to  "work  the  world!" 


Gotham  Hobby  Corp.  Florida,  1955 

107  East  126th  St. 
New  York  35,  N.  Y. 
Gentlemen: 

I'd  like  to  express  my  enthusiasm  and  satisfaction 
regarding  your  20-meter  rotary  beam  antenna.  I  pur- 
chased one  of  your  standard  two-element  units  in 
February  of  this  year.  Prior  to  this  time  I  had  been 
using  a  collinear  array  about  one  wavelength  above 
ground.  'I'he  transmitter  feeding  this  antenna  had  a 
power  output  of  about  35  watts,  and  results  were  quite 
discouraging. 

\\  hen  my  Gotham  arrived,  it  was  easily  assembled 
in  a  couple  hours.  The  same  transmitter  was  used  to 
excite  the  Gotham  antenna,  using  the  same  power  as 
before.  l{esults  have  been  quite  gratifying,  and  it  is 
interesting  to  note  that  in  the  three  months  since  using 
the  Gotham  antenna,  I  have  worked  87  foreign  coun- 
tries, all  continents,  and  30  zones. 


EVERY    FULL-SIZE    GOTHAM    ROTARY   BEAM   IS  ENGIN 

Your  Gotham  comes  to  you  completely  fabricated,  made 
(except  for  the  polystyrene  insulator)  entirely  of  new,  rust- 
less, first-quallly  mill  stock  aluminum.  You'll  find  no  link 
coupling,  no  complicated  mounts,  no  tuning  stubs.  You  get 
good,  solid  aluminum  tubing — and  more  of  it,  in  both  length 
and  thickness  (the  only  true  gauge  of  $  value)! 
No  flimsy  wire,  no  wood  to  rot  or  weather-proof.  W

I  am  able  to  keep  schedule  w  ith  amateur  radio * 

in  the  Cape  \  erde  Inlands  every  week.  It  tras  impos- 
sible to  even  hear  lliis  station  before  using  the  Gotham 
beum. 

Fxlremely  high  uinds  are  i)revalent  in  this  part 
of  i'lorida.  ihe  (jotliani  beam  has  withstood  blows 
in  excess  of  50  miles  an  hour  without  failure. 

The  elements  bentl  almost  double  in  these  high 
winds,  but  readily  return  to  their  original  configura- 
tion when  the  wind  abates.  I  feel  that  this  is  an 
extremely  important  feature  of  the  Gotham  antenna. 
I  have  enthusiastically  recommended  Gotham 
to  all  the  hams  who  ask  what  type  I  am  using  (and 
most  of  them  do,  when  I  tell  them  the  amount  of 
power  I'm  using).  I  wish  you  every  success  with  your 
product,  and  feel  that  it  is  well  worth  the  modest  price. 

Y  ours  very  truly, 
(Names  and  *call  letters  upon  request.) 


EERED  FOR    SIMPLICITY,  STRENGTH,    PERFORMANCE 

Easy  assembly,  simple  and  quick  matching  of  line  to  antenna. 
Yet  Gotham's  price  is  25^o  *o  75%  lower  than  the  "toy" 
midget  beams  which  Gotham  so  easily  out-performs.

mercially-built amateur  radio  equipment.  BIP  reported 
that  Field  Day  was  very  successful;  more  than  100  contacts 
were  tallied.  With  Dad's  new  call,  KN6JUK,  the  Harlan 
boys  now  have  a  complete  "ham  family."  Sons  Harry  and 
John  are  K6AES  and  W60ST.  W6IKO  and  club  treasurer

National  Convention  in  Santa  Monica.  The  HAMS  (Red 
Cross  group)  and  the  Hi-50  Club  say  there  have  been  lots 
of  band  openings  on  6  meters  lately.  The  29ers  invite  all 
amateurs  locally  who  have  10-meter  installation  in  mobile 
to  join  them  in  montlily  transmitter  hunts.  The  29ers  held 
its  annual  breakfast  July  24th  at  Fosters  Restaurant  with  a 
good  turnout.  PKI  is  operating  at  Devenshire  Uranium 
Supplies  in  San  Carlos.  PCN  was  hostess  for  the  ladies' 
club  at  the  July  meeting  and  it  served  two  purposes.  The 
OMs  also  were  invited  and  all  enjoyed  a  housewarming  at 
PCN's  and  GCV's  new  QTH.  The  Tamalpais  Radio  Club 
held  its  first  after-summer  session  meeting  on  Sept.  9th. 
The  Humboldt  Radio  Club  had  an  ARRL  membership 
drive  wth  good  results.  GDV,  YQZ,  K6CNV,  W6BWV,

Asst.  GHI.  JWF  finished  the  new  100-watt  Heathkit  and 
expects  to  be  on  the  air  soon.  CBE  has  the  new  pair  of 
4-125As  final  finished  and  working  swell.  He  received  MARS 
appointment  and  has  been  keeping  daily  skeds  with  mobile 
PKH  on  his  Eastern  trip.  SWP,  Pat  Ryan,  has  been  criti- 
cally iU  and  wiU  not  be  heard  on  the  air  for  some  time.  He  is 
in  Ward  74-A,  Oak  Knoll  Hospital,  Oakland,  Calif.  His 
XYL  reports  that  Pat  may  never  be  active  in  radio  again. 
His  many  friends  will  be  sorry  to  hear  this  as  Pat  was  very 
active  on  the  nets  and  a  faitMul  worker.  WB  has  accepted 
the  assignment  as  chairman  of  the  National  ARRL  Con- 
vention wliich  will  be  held  in  San  Francisco  in  '56.  With 
Bud  as  top  man  tlie  Convention  is  expected  to  be  a  huge 
success.  Your  SCM  had  a  wonderful  time  meeting  the  boys 
of  the  "Grandpappy's  Net"  at  the  roundup  in  July  at 
KUP's  QTH  in  Ruth,  Cahf.,  and  attended  the  Humboldt 
Radio  Club  meeting  in  Eureka  and  then  on  to  the  Oregon

was  had  and  I  enjoyed  meeting  7SY  (at  the  Salem  OEN 
Picnic)  and  many  of  the  other  fellows  I  had  talked  to  over 
the  air.  I  also  met  that  swell  fellow,  7FIX,  who  does  such  a

other  activity.  VFN  and  VN  members  cooperated  in  the 
AREC  "Hurriiane  Drill,"  which  is  designed  to  prevent  the

BRIDGE 


The  Millen  90672  Antenna  Bridge  is  an  accurate  and  sensitive 
bridge  for  measuring  impedances  in  the  range  of  5  to  500  ohms 
at  radio  frequencies  up  to  200  mc.  //  is  entirely  different  in 
basic  design  from  previous  devices  offered  for  this  type  service 
inasmuch  as  it  employs  no  variable  resistors  of  any  sort.  The  vari- 
able element  is  an  especially  designed  differential  variable  ca- 
pacitor capable  of  high  occurocy  and  permanency  of  calibration 
over  a  wide  range  of  frequencies.  A  grid  dip  meter  such  as  the 
Millen  90651  may  be  used  as  the  source  of  RF  signal.  The 
bridge  may  be  used  to  measure  antenna  radiation  resistance, 
antenna  resonance,  transmission  line  impedance,  standing  wave 
ratio,  receiver  input  impedance  and  many  other  radio  frequency 
impedances.  By  means  of  the  antenna  bridge,  an  antenna  match- 
ing unit  may  be  adjusted  so  as  to  provide  the  minimum  standing 
wove  ratio  on  the  radiation  system  at  all  frequencies.

GEORGIA  —  SCM,  George  W.  Parker,  W4NS  —  SEC: 
CFJ.  PAMs:  ACH  and  LXE.  RMs:  MTS  and  OCG.  It  is 
with  much  regret  that  we  accept  the  resignation  of  OPE 
as  SEC.  Abbott  has  done  an  outstanding  job  in  this  office, 
and  we  are  very  sorry  that  his  job  will  make  it  impossible 
for  him  to  continue.  However,  we  were  fortunate  in  secur- 
ing the  services  of  CFJ,  of  Atlanta,  to  fill  the  vacancy. 
We  have  every  confidence  that  Bill  will  carry  on  with  the 
work  Abbott  has  so  well  begun.  DX-lOOs  are  sprouting  all 
over  Atlanta.  They  can  be  found  in  the  shacks  of  N8,

SANTA  BARBARA  — SCM,  William  B.  Farwell. 
\V6QI\V  —  The  Santa  Barbara  Hamfest  held  in  July  was 
a  roaring  success,  as  was  Ventura's  held  in  August.  K6BV/C 
is  the  first  RTTY  station  in  Santa  Barbara.  Sorry  to  see 
8BN,  the  c.w.  traffic  net,  fold  up  for  lack  of  interest.  The 
Tri  County  (3820  kc.)  and  the  Peanut  Whistle  (3860  kc. 
'phone)  Nets  still  cover  the  section  for  traffic  at  noon,  and 
ALN  (3975  kc.)  is  a  good  representation  at  night.  The 
Ventura  Field  Day  group  got  its  activities  "taped"  and 
released  over  a  broadcast  station  with  a  swell  plug  for  the 
hams  and  their  emergency  activities.  KN6LFQ  also  was 
interviewed  at  KTMS,  Santa  Barbara,  at  a  later  date, 
giving  amateurs  another  big  boost.  Tri-County  newspapers 
are  opening  up  with  articles  and  interviews  with  hams. 
Public  reaction  is  very  favorable.  We  have  good  c.d.  and 
AREC  groups  now  with  K6KPU,  as  SEC,  ready  for  any 
emergency.  I  am  very  pleased  with  the  progress  made  by 
all  clubs  in  the  South  Barbara  section.  There  will  be  a 
full  traffic  report  next  month.

went  to  the  track  meet  at  Houston  July  24-27.  He  also 
participated  in  the  CD  C.W.  Contest.  NVH  has  his  over- 
seas orders.  We  are  glad  to  get  your  traffic  reports,  but 
please  just  send  a  line  or  two  of  happenings.  KN5BCV 
broke  his  collar  bone  and  shoulder  blade  the  day  he  re- 
ceived his  call.  DTA  is  going  mobile  in  August.  AWT  is 
finishing  a  modulator  but  must  build  a  beam  yet.  ACK 
took  3  weeks  to  build  but  has  an  FB  Viking  Ranger.  TTU

—  Asst.  SCM:  Ewing  Canady,  5GIQ.  SEC:  KY.  RM: 
GVS.  PAMs:  PML,  SVR,  and  ROZ.  A  look  at  the  traffic 
totals  shows  clearly  the  results  of  hot  weather  and  un- 
favorable band  conditions.  Increased  openings  on  the 
10-meter  band  have  had  a  definite  effect  on  the  75-meter 
band  and  there  have  been  some  indications,  such  as  skip 
and  dead  areas,  that  the  75-meter  band  will  become  in- 
creasingly poor  for  daytime  operation.  The  Novice  crop 
has  been  picking  up,  as  quite  a  number  have  been  reported 
around  the  State,  including  KN5BXZ  and  KN5BPX.  Also 
the  three  ten-year-old  licensees  in  McAlester  have  gotten 
their  General  Class  tickets  and  are  heard  on  the  air  quite 
frequently.  Several  DX-lOOs  are  in  operation  around  the 
State  and  are  putting  out  good  signals.  Many  hams  are 
reporting  from  vacation  trips  and  to  military  and  National 
Guard  camps.  There  was  some  excellent  newspaper  pub- 
licity from  Holdenville  on  ADC,  NVD,  PGN,  TKI,  and 
WN5BXZ:  also  publicity  on  OQT  and  YL  and  XYL 
operators  in  Oklahoma  City,  all  with  pictures.  All  Asst. 
Directors  got  a  fine  letter  from  our  grand  West  Gulf  Divi- 
sion Director,  CF,  and  he  certainly  should  get  the  help 
and  cooperation  he  is  requesting.  Dad  promises  a  letter  at

Medium-Power  Transmitter 

(Continued  from  page  19) 

ch.'irt  and  parts  list  were  calculated  to  provide  a 
Q  of  al)out  12  in  the  plate  tank  circuit,  for  a  plate- 
voltago/plate-current  ratio  of  about  13:1  (2000 
volts,  150  ma.).  Departure  from  this  ratio  will 
make  it  necessary  to  change  some  of  the  values  of 
the  tank  components  if  a  Q  of  12  is  to  be  main- 
tained.'' Ideally,  the  transmitter  should  work  into 
a  50-ohm  antenna  or  an  antenna  coupler  that  will 
present  50  ohms  to  the  transmitter,  Init  reason- 
able variations  can  be  compensated  for  nicely 
by  juggling  the  loading  capacitors  and  the  value 
of  Li4.  A  little  time  invested  in  getting  the  trans- 
mitter adjusted  to  a  i)articiiiar  antenna  will  pay 
off  in  signal  reports.

As  mentioned  earlier,  the  rig  described  here 
has  been  in  use  for  over  a  year,  on  80,  40,  and  20 
for  the  most  part,  and  has  been  a  pleasure  to 
operate.  Changing  bands  is  a  simple  process,  and 
is  done  very  quickly  —  a  great  help  in  the  SS 
contest.  Living  in  a  relatively  strong  TV-signal 
area,  with  a  TV  antenna  about  every  50  feet  in  all 
directions  as  far  as  the  eye  can  see,  not  a  single 
TVI  complaint  has  been  received  to  date.  This 
includes  our  own  TV  set,  the  antenna  for  which 
is  about  10  feet  from  the  20- meter  ground  plane, 
the  mast  of  which  also  serves  to  hold  up  one  end 
of  the  80/40-meter  horizontal  antenna. 

Many  complimentary  reports  have  been  re- 
ceived on  the  keying  and  no  clicks  can  be  heard 
off  frequency,  even  by  the  nearest  locals.  Opera- 
tion is  full  break-in,  and  since  a  TVG  unit '  has 
been  installed  in  the  station  receiver,  switching 
from  receive  to  transmit  involves  only  the  move- 
ment of  the  hand  to  and  from  the  bug. 

Application  of  Tekni-Cals  to  the  front  panel, 
plus  careful  layout  has  resulted  in  what  we  feel 
is  a  "finished"  look. 

The  author  would  like  to  acknowledge  with 
gratitude  the  contributions  made  by  W2RDK, 
W2HSZ,  and  K2E0C  during  the  design  and 
construction  of  this  rig,  and  the  patience  of  my 
XYL,  who  puts  up  with  this  sort  of  thmg. 

*  A  lOO-M/if.  tank  capacitor  is  sufficient  over  the  plate- 
voltage  range  of  600  to  3000  (assuming  a  plate  current  of  150 
nia.,  and  a  50-olim  load  in  each  case)  for  all  bands  except  80 
meters.  On  80  meters,  100  M^f.  is  adequate  for  2000  volts  or 
more.  A  IbO-fi/if.  capacitor  is  recommended  for  plate  voltages 
down  to  1000,  while  a  200-Ai/tif.  unit  should  be  provided  if 
operation  down  to  600  volts  is  contemplated.  Also,  for  80- 
meter  operation  into  a  50-olim  line,  an  output  capacitance 
adjustable  up  to  900  or  1000  MMf-  would  provide  greater 
assurance  of  obtaining  a  proper  match.  —  Ed.

gottuig.  "Yeah,"  he  says,  with  a  sour  look,  "I've 
been  listening  to  you  lately  but  if  I  have  to  have 
a  note  like  a  bunch  of  sparrows  just  to  get  to  talk 
with  some  guy  a  little  farther  awa.y  than  I  can 
get  normally  I'll  be  doggoned  if  I  don't  jest  lock 
up  the  shack  and  take  up  photography."  If  I  had 
been  set  up  with  store  teeth  then  I  sure  would 
have  dropped  my  uppers.  The  guy  meant  it!  I 
know  he  did  because  a  .year  later  he  was  off  the 
air  and  so  help  me  he  has  never  returned. 

It  makes  me  sad  to  think  about  Old  Bill.  He 
had  one  of  the  best  fists  on  the  air  and  more  fun 
with  his  hamming  than  any  three  hams  are  en- 
titled to  have.  But  he  had  an  opinion  and  he 
defended  it  even  to  the  point  of  dropping  his 
hobl>y.  I  have  always  thought  he  just  couldn't 
endure  the  thought  of  learning  a  new  set  of  tech- 
nicjues  in  order  to  hold  his  own  with  the  rest  of 
the  gang.  After  all,  spark  operation  was  simple 
and  the  new  c.w.  method  was  much  more  com- 
plicated by  comparison.  Oh  well,  I've  seen  many 
Old  Bills  in  other  fields  and  I  guess  there's  noth- 
ing I  can  do  about  them  even  if  they  do  make  me 
sad. 

Along  about  last  year  Old  Joe  went  single 
sideband.  Now  the  whole  gang  of  locals  are  say- 
ing mean  things  about  him  and  his  "rubber- 
voiced"  'phone  communications.  They  say  he  is 
taking  up  too  much  of  the  band  and  I'm  kinda 
inclined  to  agree  with  them  when  I'm  listening 
to  a.m.  on  my  receiver.  But  you  know,  I  notice  he 
doesn't  have  the  least  bit  of  trouble  with  QRIVI

Progress  is  necessary  and  it  must  come.  The 
s.s.b.  bo}-s  tell  some  fantastic  stories  about  the 
wonders  of  their  'phone  method.  Their  stories  are 
almost  too  good  to  be  true  and  I  can't  help  but 
be  suspicious  of  them.  If  what  they  say  is  even 
partially  true,  s.s.b.  does  represent  progress.  It 
looks  to  me  as  though  all  this  fuss  about  s.s.b.  is  be- 
cause the  new  method  is  gumming  up  the  old. 
When  c.w.  came  along,  it  was  the  old  method 
which  interfered  with  the  new.  But  the  new 
method  was  the  better  method.  It  represented 
progress  and  it  did  win  out,  but  it  took  several 
years  to  win  the  boj's  over. 

It  seems  to  me  as  though  both  sides  in  this 
s.s.b.-a.m.  row  have  a  few  new  tricks  to  learn.  It 
seems  the  s.s.b.  boj's  need  to  be  very  sure  their  rigs 
are  clean  and  the  a.m.  boys  have  a  few  more  things 
to  learn  about  their  receivers.  It'll  take  time  for 
the  row  to  be  decided,  but  all  concerned  should 
wait  and  see.  Many  on-the-air  friendships  will  be 
broken  up  by  the  a.m.  vs.  s.s.b.  row.  Many  of  the 
voices  which  are  now  so  familiar  as  I  tune  across 
the  band  will  no  longer  be  heard.  It  makes  me 
sad  to  see  this  history  repeating  itself.  Seems  it 
is  just  my  bounden  duty  to  ask  both  sides  to  be 
patient  if  the  urge  to  spout  off  about  opinions 
comes  along.  Seems  I've  just  got  to  ask  all  the 
boys  to  say  as  little  as  possible  to  hurt  the  other 
fellow  until  time  gives  us  the  answer.  Wait  until 
time  does  give  that  answer,  please! 

You  know,  since  QRM  is  so  heavy,  it  would  be 
foolish  to  get  into  this  subject  on  the  air.  I  believe 
I'll  just  give  Old  Joe  a  call  on  the  land  line  so  I 
can  go  and  sit  with  him  and  really  look  into  this 
s.s.b.  business  first  hand.  It  might  need  a  lot  of 
looking  into.

as  far  back  against  the  front  seat  as  possible. 
This  location  keeps  the  control  within  easy 
reach,  although  nothing  of  the  cable  is  in  sight. 
The  hole  in  the  car-body  floor  is  also  hidden  and 
is  easily  covered  when  the  installation  is  removed. 
No  fastener  or  adapter  could  be  found  for  the 
cable  at  the  tuner  end,  so  it  was  merely  clamped 
to  the  car  body  about  a  foot  from  the  tuner. 

In  connecting  the  line  that  runs  between 
the  thermocouple  on  the  unit  and  the  r.f. 
ammeter  on  the  dash  board,  be  sure  to  observe 
the  polarity  markings  on  both  the  thermocouple 
and  the  meter. 

Adjustment 

Operation  of  this  unit  is  so  simple  and  straight- 
forward 1^  that  ^  little  explanation  is  necessary. 
However,  a  few  pointers  may  be  helpful  in  getting 
best  results  on  the  first  trial.  Mount  the  unit  as 
close  as  possible  to  the  receptacle  at  the  base 
of  the  antenna.  Prune  the  loading  coil  so  that 
about  five  turns  of  the  rotocoil  are  in  the  circuit 
at  the  high-frequency  end  of  the  band.  This  will 
mean  about  seven  turns  less  on  the  Hi-Q  type 
Master-Mount  coil,  or  slightly  more  on  coils  of

smaller  diameter.  Here  is  where  a  grid-dip  meter 
comes  in  handy,  although  the  job  is  by  no  means 
impossible  using  just  the  transmitter  tuning 
indicator  and  the  antenna-current  indicator. 
Now  trj^  tuning  the  antenna  to  the  low  end  of 
the  band  by  means  of  the  tuner.  You  will  be 
surprised  at  how  few  more  turns  of  coil  arc- 
necessary.  It  is  advisable  to  mark  each  end  of  the 
band  on  the  dial  of  the  tuner  with  paint  or  white 
ink.  After  these  adjustments  are  made,  operation 
consists  onty  of  tuning  the  transmitter  and  then 
tuning  the  antenna  for  maximum  indication  of 
the  r.f.  ammeter.  It  may  be  found  that  with  very 
low-power  transmitters  (10  watts  or  less)  there 
is  only  a  slight  indication  of  current  at  exact 
resonance.  Meter  deflection  can  be  increased 
by  adjusting  the  leads  to  the  meter  transformei- 
so  that  slightly  more  than  one  turn  surrounds 
the  core. 

As  might  be  expected,  the  entire  system  works 
equally  well  for  receiving.  The  antenna  change- 
over relay  should  be  placed  in  or  near  the 
transmitter.

the  unit  becomes  inoperative. 

With  Si  closed,  everything  is  ready.  When  the 
key  is  up  the  receiver  is  heard;  when  the  key  is 
down  a  sidetone  is  heard  and  the  transmitter  is 
keyed.  The  oscillator  tone  level  can  be  adjusted 
with  the  gain  control  on  the  unit,  while  the  re- 
ceiver level  is  controlled  at  the  receiver.  If  the 
station  being  worked  wishes  to  break  in,  his  sig- 
nals can  be  heard  between  the  chai'acters  being 
transmitted. 

Since  the  receiver  is  actually  on  during  key- 
down  conditions  (even  though  it  appears  to  be 
off  in  the  headphones),  care  should  be  taken  not 
to  damage  the  receiver  by  r.f.  overloading.  The 
monitor  has  been  used  successfully  at  WlCUT 
with  a  cathode-keyed  transmitter  running  as 
high  as  200  watts  input.  For  simplicity,  separate 
transmitting  and  receiving  antennas  are  used. 
The  unit  cannot  be  used  with  grid-block  keyed 
transmitters  —  it  is  designed  for  cathode-keyed 
rigs  only. 

If  the  transmitter  and  receiver  are  turned  off 
the  monitor  can  be  keyed  and  used  as  a  code- 
practice  oscillator.  The  sidetone  will  appear  in 
the  headphones  as  the  unit  is  keyed. 


K2KTX  tells  us  that  during  an  operation, 
K2IWT  was  reported  to  have  been  tapping  out 
code  while  unconscious  from  the  effects  of  the 
anesthesia.  Evidently  K2IWT  is  one  fellow  who 
does  not  have  to  worry  alwut  learning  the  code 
s'lbconsciously.

What  \s  This  Thing 

Called  the  ''Hump'' 

in  CODE? 


JL  HE  hump  (around  8  words)  is  the 

thing  that  tells  you  you  have  wasted 

your     time     by     starting    out     wrong.  ^ 

Thirty  years  ago  when  we  started  teach-  V_      "" 

ing  Code  our  students  too  ran  head-on 

into  the  hump.  We  went  to  work  to  find  out  why.  TWO-PHASE, 

STEP  BY  STEP  instruction  is  the  perfect  answer.  In  this  method 

dotdash  is  not  A.  The  SOUND  resulting  from  dotdash  is  A.  There 

is  also  the  important  factor  of  correct  timing.  If  the  signals  are  not 

timed  correctly  the  resulting  sound  will  not  be  correct.  There  are 

many,  many  things  connected  with  proper  Code  instruction,  many 

of  them  so  small  they  seem  inconsequential.  Others  are  so  technical 

that    many   so-called   experts  fail    to    understand    them.    It's   a   long 

story  but  I  have  it  all  written  up  and  will  be  glad  to  send  it  to  you. 

A  postcard  will  bring  you  the  full  story.

{Continued  from  page  39) 

while  holding  the  key  down.  If  the  amphfier  is 
neutralized,  the  grid  current  will  drop  to  zero 
and  the  lamp  bulb  will  go  out.  Hold  the  key  down 
only  for  a  second  or  two  when  making  these  tests, 
because  the  amplifier  tube  draws  e.xcessive  cur- 
rent when  it  has  no  grid  excitation. 

If  grid  current  is  present  with  the  crystal 
removed  it  indicates  that  the  amplifier  is  os- 
cillating and  must  be  neutralized.  Hold  the  key 
down  and  adjust  Cn,  the  neutralizing  capacitor, 
to  a  setting  that  shows  no  grid  current  on  the 
meter.  Use  a  small  insulated  screw  driver  to 
adjust  the  neutralizing  capacitor. 

When  the  amplifier  is  neutralized  on  80  meters, 
reinsert  a  40-meter  crystal  and  tune  the  rig  up  on 
15.  Make  the  same  tests  and  follow  the  procedure 
as  on  80.  If  the  amplifier  is  not  already  neutralized 
on  15,  the  setting  of  Cn  should  not  have  to  be 
changed  very  much  to  stabilize  the  amplifier. 
When  the  amplifier  is  neutralized  on  15,  it  should 
be  stable  on  all  bands.  It  is  not  necessary  to  neu- 
tralize on  10  meters  because  the  amplifier  works 
as  a  frequency  doubler. 

Additional  Information 

In  its  modified  condition,  the  transmitter  can 
be  used  with  80-meter  crystals  for  80,  40,  and  20. 
A  40-meter  crystal  will  take  care  of  40,  20,  15, 
and  10.  In  the  15-10-meter  position,  the  oscillator 
tuning  is  near  minimum  capacitance  for  15  and 
near  maximum  for  10  (20-meter  drive  to  the 
amplifier  on  this  band) .     »*»:  -ii  -"' 

A  very  noticeable  keying  chirp  was  present 
both  before  and  after  modification,  most  of  it 
being  caused  by  the  change  in  oscillator  screen 
voltage  between  the  key-up  and  key-down  con- 
ditions. The  change  was  minimized  by  connect- 
ing a  68,000-ohm  1-watt  resistor  from  Pin  6  of  the 
oscillator  tube  socket  to  chassis  ground. 

To  convince  yourself  that  the  modifications 
described  here  are  worth  while,  try  this  test: 
Before  making  any  changes,  connect  a  40-watt 
lamp  bulb  to  the  output  terminal  and  tune  the 
rig  up  on  each  band,  observing  the  brilliance  of 
the  lamp.  After  the  modification,  go  through  the 
same  procedure.  You  won't  need  dark  glasses, 
but  you  should  be  pleasantly  surprised  by  the 
difference  in  output.  And  don't  forget  —  trans- 
mitters may  be  rated  by  input,  but  it's  the  out- 
put that  works  'em!

W9EET,  Chicago,  III.  — Ten  days  of  operating  on  50

Another  Communicator  Hint 

In  June  QST  we  described  a  method  for  using  the  Gonset 
Communicator  as  a  converter  with  a  communications 
receiver  as  the  i.f .  This  involved  retuning  of  the  i.f.  system 
slightly,  so  it  might  sca,re  off  a  potential  user.  (The  i.f.  is 
broad  and  the  adjustment  is  in  no  way  critical.)  WIEOI 
goes  us  one  better  by  wrapping  an  insulated  wire  around 
the  leads  to  the  noise-clipper  switch,  poking  this  through 
the  back  screen  on  the  Communicator  so  that  it  protrudes 
about  one  inch.  A  piece  of  coax  is  connected  between  this 
wire  and  the  communications  receiver,  in  the  usual  manner. 
Enough  i.f.  energy  on  6  Mc.  is  thus  made  available  to  give 
a  reading,  on  noise  alone,  of  S6  on  WlEOI's  NC-183  S- 
meter.  No  readjustment  of  the  i.f.s  is  needed,  and  the 
\vire  may  be  pulled  out,  leaving  the  unit  in  exactly  its 
original  condition.

wife  Alice  has  done  a  lot  of  operating  on  80  and  2  since 
becoming  WNIDQF.  The  Perrys  think  the  answer  is  to 
set  the  XYL's  rig  right  in  the  kitchen — cooking  and 
QSOing  blend  well  together.  With  the  pet  parakeet

ment  of  location  (if  station  identification  is 
necessary  to  carry  on  the  service,  tactical  calls 
or  other  means  of  identification  will  be  utilized 
in  accordance  with  12.246). 
(d)  The  radio  station  carrier  shall  be  discontinued 
during  periods  of  no  message  transmission. 

12.194  Special  Operation.  In  certain  cases,  the  Federal 
Communications  Commission  may  authorize  specific  sta- 
tions to  operate  during  a  CONELR.\D  RADIO  ALERT  in 
a  manner  not  governed  by  these  Rules,  provided,  such  op- 
eration is  determined  to  be  necessary  in  the  interest  of 
National  Defense  or  the  public  welfare. 

12.195  Resumption  of  Normal  Operation.  At  the  conclu- 
sion of  a  CONELRAD  RADIO  ALERT,  each  standard, 
FM  and  TV  broadcast  station  will  broadcast  a  CONELRAD 
RADIO  ALL  CLEAR  MESSAGE.  Unless  otherwise  re- 
stricted by  order  of  the  Federal  Communications  Com- 
mission, normal  operation  of  stations  in  the  Amateur  Radio 
Service  may  be  resumed  upon  reception  of  the  CONELR.\D 
RADIO  ALL  CLEAR.  Only  the  CONELRAD  RADIO 
ALL  CLEAR  will  authorize  termination  of  the  CONEL- 
RAD RADIO  ALERT. 

12.196  CONELRAD  TESTS.  So  far  as  practicable,  tests 
and  practice  operation  will  be  conducted  at  appropriate 
intervals. 

CODE  PRACTICE  FROM 
VOICE  STATIONS 

Over  the  years  various  amateur  stations  have 
conducted  programs  of  instruction  in  the  In- 
ternational Morse  Code  to  help  newcomers  ac- 
quire sufficient  skill  for  their  tickets  (e.g.,  see  p. 
69,  May  QST).  In  some  instances  this  activity  is 
conducted  on  the  voice  bands,  with  an  audio  os- 
cillator in  front  of  the  mike  so  that  code  charac- 
ters and  voice  instruction  might  be  interspersed. 
A  special  action  of  FCC  some  twenty  years  ago 
made  an  exception  for  this  emission  in  code  prac- 
tice on  A-3  bands,  but  because  of  its  age  and  ob- 
scurity there  has  been  difficulty  in  recalling  its 
text  and  application.  As  the  result  of  conversa- 
tions between  ARRL  and  FCC  it  has  now,  log- 
ically, been  decided  to  write  the  exception  into 
our  regulations,  and  the  Commission  has  pro- 
posed to  add  a  Section  12.114  (b)  to  our  rules  to 
provide  that  "Whenever  code  practice,  in  ac- 
cordance with  Section  12.106  (d),  is  conducted  in 
bands  authorized  for  A-3  emission,  radiotele- 
phony  tone  modulation  may  be  utilized  when 
interspersed  with  appropriate  voice  instructions." 
Any  comment  on  the  proposal  must  be  filed  bj'^ 
November  15th. 

AT  PRESS  TIME  —  420-MC.  RULING 

FCC  has  just  issued  an  order  providing  that 
effective  October  1st  the  present  420-Mc.  limit 
of  50  watts  peak  power  will  be  changed  to  50 
watts  plate  input. 


Amateuis  everywhere  will  be  saddened  to 
note  that  the  name  of  Edward  Clark  Crossett, 
W6DZH,  ex-WlCCZ,  appears  in  Silent  Keys  this 
month.  During  the  late  Twenties,  many  experi- 
ments with  beam  antennas  were  conducted  by 
prominent  amateurs  at  the  site  of  WICCZ,  Mr. 
Crossett's  station  at  Wianno,  Mass.

ances at  the  kilowatt  level.  Single  knob  bandswitching,

Equipped  with  a  heavy  duty  antenna  changeover  relay, 
the  Kilowatt  "Matchbox"  permits  separate  matching  of  the

CRYSTAL  STORAGE  RACK 

WE  find  it  necessary  to  have  quite  a  number  of 
crj'stals  on  hand  to  cover  the  whole  of  any 
amateur  band.  When  changing  frequency,  it  has 
l)een  necessary  in  the  past  to  dig  and  sort  through 
a  bo.\  or  jar  until  the  appropriate  crystal  was 
located. 

The  confusion  associated  previously  with  the 
selection  of  a  crystal  has  been  eliminated  by  the 
rack  showii  in  Fig.  7.  The  holder  was  made  from  a 
l)iece  of  oak  board  measuring  %  by  23^^  by  6 
inches.  The  four  rows  of  holes  shown  in  the  draw- 
ing are  made  with  a  No.  39  drill  and  accommodate 
a  total  of  20  Type  FT-243  crystals. 


Fig.  7  — This 
crystal  storage 
rack  can  be  an  at- 
tractive and  use-  g  ' 
ful  addition  to 
the  shack. 


■ZVz" 


The  size  of  the  rack  was  determined  by  the 
number  of  crystals  on  hand  and  may  be  altered 
to  suit  the  individual  requirements.  Oak  board 
was  selected  because  of  its  hardness,  thereb>'  pre- 
venting the  enlargment  of  the  holes  through  pro- 
longed usage.  The  whole  unit  was  finished  in  light 
oak  stain  and  coated  with  good  varnish.  A  back- 
ing of  pool  cloth  is  an  extra  refinement  and  a  pair 
of  screw  eyes  permit  hanging  on  a  wall.

The  No.  90672 
ANTENNA  BRIDGE 

The  Millen  90672  Antenna  Bridge  is  an  accurate 
and  sensitive  bridge  for  measuring  impedances 
in  the  range  of  5  to  500  ohms  at  radio  frequen- 
cies up  to  200  mc.  It  is  entirely  different  in  basic 
design  from  previous  devices  offered  for  this 
type  service  inasmuch  as  it  employs  no  variable 
resistors  of  any  sort.  The  variable  element  is  an 
especially  designed  differential  variable  capaci- 
tor capable  of  high  accuracy  and  permanency 
of  calibration  over  a  wide  range  of  frequencies. 
A  grid  dip  meter  such  as  the  Millen  90651  may 
be  used  as  the  source  of  RF  signal.  The  bridge 
may  be  used  to  measure  antenna  radiation 
resistance,  antenna  resonance,  transmission 
line  impedance,  standing  wave  ratio,  receiver 
input  impedance  and  many  other  radio  fre- 
quency impedances.  By  means  of  the  antenna 
bridge,  an  antenna  matching  unit  may  be 
adjusted  so  as  to  provide  the  minimum  stand- 
ing wave  ratio  on  the  radiation  system  at  all 
frequencies.

N«w  Hallicraftare  SX-IOO 
Communications  Rocoivor 


And  the  new  Hallicrafters  SX-100  is  another  example. 

Featuring  such  modern  circuitry  as  double  I-F  con- 
version and  single-sideband  reception,  the  SX-100  is  the 
newest  addition  to  the  Hallicrafters  line  that  has  been 
making  communications  history  on  the  amateur  bands 
for  many  years. 

In  this  fine  receiver,  as  in  many  other  leading  amateur 
and  commercial  designs,  RCA  Receiving  Tubes  are  speci- 
fied—because the  tests  of  time  have  proved  that  RCA 
Receiving  Tubes  can  really  take  it  in  day-in  and  day-out 
operation.  High  uniformity  of  characteristics  makes  it 
possible  to  interchange  them— no  matter  where  or  when 
you  buy  them— without  a  lot  of  circuit  readjustment. 
RCA  Receiving  Tubes  help  with  greater  background 
quietness  enabling  you  effectively  to  boost  receiver  sensi- 
tivity without  "knocking  out"  the  signal. 

There  is  an  RCA  Tube  for  practically  every  receiver 
and  transmitter  application  in  amateur  radio.  See  your 
RCA  Tube  Distributor  for  the  types  you  need. 


NEW  RC-17 
RCA   RECEIVING 
TUBE  MANUAL 

Includes  basic  tube  the- 
ory, installation  and  oper- 
ation data,  application 
help,  charts,  circuits. 
Revised  and  up-to-date. 
Only  60  cents,  from  your 
RCA  Tube  Distributor.
