Cat. No. 200-509 Stationmaster Collinear Gain Antenna
is designed to meet the ever increasing needfor high antenna
gain in minimum spaceand at
lowest cost. This antenna,consisting of a number of collinear
radiating elementsfed inphase
and encapsulatedin a continuous weatherproof fiberglass
housing, meets the above requirements.Low overallweight
eliminates the need for extensive erection equipment required by previous antennas
offering equal power gain. The
input fitting on these antennas
is a standard Type N male connector mounted at the end of
an 18" flexible terminal extension, Designed for maximum
strength with minimum crosssection, Cat. No. 200-509 is
capable of withstanding winds
in excessof 100 MPH.

of nry experiences

may follow.

it has grown from a few hundred licenseesto more than 250,000. The equipment has changed
fr.om relatively sintple hontentade gear to complex receivers and transmitters of sophisticated
design and, often, of comntercial manufacture. The frequencies available for amateut use have

present harmonically related bands located throughout the spectrum. Under normal conditions,
amateurs can now work each other anywhere in the world, at any time of night or day. As we look
back, it has been a most extraordinary developn-rent.
Yet, in the processof this growth and progress, there is danger we may have taken some things
for granted, rvithout analyzing them very carefully, simply because they have become an accrlstomed habit. One of these is the continued availability of our high frequency bands from 1.8 to

led by Hiram Percy Maxim, Amateur Radio was
recognizedfor the first time as a full-fledged
TelecommunicationsService. This was despite
vigorous opposition by many other countries
who wished to give Amateur Radio no recognition whatever, or at best, to class it as an
experimental hobby. The view of the United
Stateswas that amateurs had performed in the
"public interest, convenience
and necessity";
they were competent in their operations, and
their technical contributions were of such farreaching significancethat they were justified in
being formally designatedas a "Service."
This does not in itself guaranteeus any frequency allocations. We will have to fight for
them in the future just as hard as we have in
the pas!-and probably a lot harder. But it does
make the job easierbecausewe have a recognized
status,
In subsequentconferences,the United States
continued to maintain its support of the Amateur Service,and, in each instance,it has been
joined by enough other countries-Canada in
particular-to constitute a majority. However,
there have beenrepeatedproposalswhich, if they
had prevailed, would have severely reduced or
eliminated our amateur bands. As we shall see,
the latter attitude will probably be much stronger
in the future than heretofore.
At the next Conference,which may well take
place within three to five years. there are expectedto be more than 100 nationsparticipating.
and each will have an equal vote. Approximately
thirty countries have come into being as brandnew nations since the last Conference in 1959,
and this will be the first such affair they have
attended. Most of them are among the rapidly
developingcountriesof Africa.
There are thirty or forty additional nations
which, although older, also have little or no
amateur activity. It is significant that many of
the proposalsto curtail amateur activitiesin past
conferenceshave been originated by this group.
All of the nations,in both of thesegroups, have
radio and communicationsproblemswhich they
feel are far more pressing than providing for
an amateur service.It requiresonly simple arithmetic to realizethat the sum of thesetwo groups
add up to substantiallymore than a majority of
the whole.
The next Conference, when it occurs, will
again be concernedprimarily with the High Frequency portion of the spectrum-from 3 to 30
mc. This is the area where the most difficult
interferenceproblems must be resolved, and it
is here. too. where our most valuable amateur
bands are located.
The pressurefor more high frequency channels is far greater than ever before. Almost all
of the newer nations-and many of the older
ones, too-feel they have a vital need for more
short-wavebroadcasting.They have great pride
in their new-found sovereigntyand they want to
8

broadcasttheir virtues, philosophiesand aspirations to the rest of the world. They feel a myriad
of listenersare eager to hear their story if only
a clear channelcould be obtained.Unfortunately,
all the channelsassignedto broadcastingat the
1959 Conferenceare already overcrowded,and
they must squeezethemselvesinto some other
part of the spectrum-at least, they hope, until
the next Conferencelearrangesthe allocationsto
their satisfaction.
The desire for more broadcastchannelsfalls
primarily in the band from 7 to 22 mc. In this
band. thesecountriesalso want more commercial
frequenciesto keep in touch with the world centers of diplomacy and commerce.
They also have an internal communications
problem. Being sparsely settled, telephone and
telegraphby land wire seem inordinately expensive, and radio links in the 3 to 7 mc part of the
spectrum appear most inviting. Again, if these
channels are occupied-as they usually arethen they move into the first vacant spot to be
found.
A number of such stationshave moved in on
us already.What is not fully realized,at least by
most amateurs,is that there will again be a concerted move to take over most-if not all-of
our amateur bands. And let us not delude ourselves,there are the votes available this time to
make it extremely difficult.
When the next Conferencetakes place, there
is .little we can do directly, as amateurs.These
conferencesare betweengovernments,and, while
the League and the IARU will have representatives present. we are only a small part of the
over-allpicture.
The final outcome will be determinedby two
things, namely ( I ) the attitude of the smaller
countries,whose votes will be decisive,and who
feel they are in desperateneed of more spacein
the spectrum;and (2) how vigorouslyour own
Government-and thoseof other countrieswhere
substantialamateur activity has been supported
-will defend our frequency allocations.
The attitude of the newer and smaller countries will be largely determinedby their own selfinterest.They will not be impressedso much by
the historic achievementsof amateur radio in the
past as by what it can do for them in the future.
It will help us in anticipating their reaction if
we ask ourselvessome straightforwardquestions.
Are we, for instance,in the daily use of our frequencies,creating the kind of image we would
like these governmentsto have about amateur
radio? Are we demonstratingour full capability
to servethe public interest?Are we trying to improve our technical competenceand keep pace
with the progressin communicationsgenerally?
Does amateur radio have a seriousside to it, or
is it primarily a hobby for entertainment?The
answersto thesequestionsand to many more like
them will largely determine what happens to
amateur radio in the immediateyears ahead.
There are seriousand well-qualified amateu.rs

outcome will depend largely upon what we, as

by literally thousandsof individuals who founcl
that chatting over the air could b..o-. u rno.i

has becomeso great that the original purposes
were lost, and the FCC is now consiiering

There is an

worth serious reflection.especiallyconsidering
the sourcefrom which it contes.
In view of all thesecircumstances.
it is useful
to consideragainjust why we have our present
frequencies.The amateurbandswere made avail_
able to us instead of to other essentialservices
becauseit was believed to be in the over_all
natjonal interest.The purposewas to create a
body of technicallycompetentand experienced
operators:who would advancewith ihe radio
art and, whereverpossible,make substantialcon_
tributions to its continued progress; and who
would be active in promoting the public welfare.
These definitionsoccur all through the legal justification for our domestic existence.In t-urn, it
is basically on these grounds that our Govern_
mental agenciesare able to support us at the
international level.
During the annual meeting,the directors con_
sidered both the international and the domestic
situationsat length.It was recognized
that unless
vigorousmeasureswere taken there was a gravc
possibilitywe might losea substantialpart o1 our
high frequencybands at the next iniernational
confelence.Furthermore,the Board concluded
this was not a matter that could be counteracted
by strenuousarguments alone. Such arguments
would have-tobe accompanied
by a genuineup_
grading of the amateurserviceitself if the futu;e
could be faced with any degreeof confidence.
It was also recognizedthat there was no single
solution to the problem, and that any chanles
which might be recommendedin licensingpio_

Prolecl Your Equipment?
Editor, CQ:
Dale and Morey (Noyember, CQ) suggest dogs as
good burglar insurance.
I suggest extreme caution to this approach! In the first
place, the Humane Society would be all over you if you
leave a dog unattended while you lake off on a vacation.
Furtlrermore, if the dog gets loose in the heavily populated areas in Nebraska, meaning primarily Lincoln and
Omaha, just the fact of being loose lays the owner open
ro a fine from 55 to Sl00-Nebraska
Statutes 54-608.
If a dog does damagc, or bites a meter reader, paper
flvE-coRE
SOTDER
ilHft;;**.,
bo), milkman, or an)'one else on your property legitiDrirtely or bites anyone ofl l"our property at all, you are
open to claims for damages-Nebraska Statutes 54-601.
If a loose clog does darnage oft tlre orvner's property,
the owner is further liable to a fine of from the amount
of the damage to twice the damage, over the liability to
civil recovery-Nebraska
Statutes 54-613. . . .
This hardening of attitude toward dogs is nationwide,
varying only in degree. It has it's roots in steadily rising
numbers of complaints involving bites, property damage,
loss of livestock, and general nuisances.
Eugene Austin, WfiLZL
1334 N. 20th Street
Lincoln, Nebraske
The authorls expert knowledge of dogs comes from material prepared for an article in a local Lincoln newspaper --Editor.
License Fees
Editor, CO:
Concerning the impending application fees, it may become quite obvious that the notion of fees will be rather
obnoxious to some of the brethren, and I would like to
point out a few facts in the event some of them label
tlre FCC unfair.
Being "amateur"
in nature, we are inc'lined to object
to anything that might indicate we are otlterwise. Observing it another way, paying for the use of something
intangible, suclr as a portion of the frequency spectrum
5-C0Rt$0tDrR
somehow doesn't harbor r conyincing apperl.
However, looking at it from still another viewpoint,
the instigationot the application fees is in reality a boon
Ior the amateur service. By its very existence,ue cs
"parasite" serYice whereby
xmrteurs will no longer be a
w e w e r e i s s u e d l i c e n s e s ,a n d l o o k e d s l t e r g r a t i s . T o a
c e r t a i n e x t e n t ,w e w i l l n o w p a y o u r o w n w a y . . .
I sincerely believe it will alleYiate a certain amount
of unfavorable censuring,and may to a ccrtain degree
create a stronger position for the amateilr service. In
a sense, the concept of application fees constitute an
excellent example of applied psychology in our favor.

To Build or Not To Build
Editor, CO:
In answer to a recent letter about today's hams relying on manufacturer's products and doing no building
of their own, I would like to state the following:
So often, details, clear to the old timer, are not fully
explained, leading Novices to confusion and frustration.
Schematics are shown without mention of parts placement, or specifications are incomplete,
I wanted to build a piece of equipment from a recent
article. The parts listed a coil thusly: 16T Air Dux f816.
How am I to know what Air Dux #816 is? Another coil
was simply 2T hookup wire. Two turns of what?
AII this discouraged me from building and I will probably buy a commercial version of the article.
I appeal to you more experienced hams, when writing
construction (and theory) articles, not to take details
for grant€d and explain things fully.

Described below is on 8-tube horne-brew sidebond

HERE'sno use denying it, sidebandis here
to stay. The question is no longer whether
to make the changeto sideband.it is how
to accomplishthe transition.
Unfortunately, many hams are saddle<iwith
expensivea.m. rigs that have suddenlylost much
of their trade-in value. Furthermoie, since a
large number of us still enjoy working a.m..
we're not overly anxious to acquire new gear
that won't operate on a.m. at all.
A logical, and relatively low cost, solution to
this dilemma is to procure an s.s.b.adapter and
hook it into your presenta.m. rig. Rather than
purchasean adapter,I decidedto build one mv_
self.The resultis the SB-8describedhere.
Costing in the neighborhoodof $t00.00. its
performancecomparesfavorablywith that of the
most expensivefactory-mades.s.b.rigs.
The unir was designedprimarily fo-r insertion
betweenthe driver and final amplifier of an a.m.
rig. However. there is no reason why you can't
tack it onto the output of a low-powe. u.-. o.
c.w. transmitter and then use a linear amnlifier
to boostthe signalseveralhundredwatts.
The adapterwill convert r.f. at the transmittins

same frequency. Thus, if you feed a 7.23 mc
carrier into it, you'll get 7.23 mc s.s.b.out. Like_
wise,if you use a21.407 mc carrier, you,ll obtain
21.407 mc sideband.

A small amount of r.f. from the companion
a.m. transmitteris applied to the grid of the balanced first mixer. Z.',.another 6JH8. The transwithin this stageand,
mitter carrier is suppressed
for all praciical purposes,doesnot appearat the
output of 25. However. the amplifieds.s.b.signal
coming from V+ is mixed in Z; with the transmitter carrier to produce sidebandoutput at a
frequency which is either the sum of. or difference between. 9 mc I I 500 cycles, and the
frequency of the transmitter.
If the transmitter is set at 7.25 mc, for example, a 16.2515mc s.s.b. signal (7.25 plus
9.0015) will appear on the plates of Z.-,.This
signal is then fed to the injection grid of Zr;. a
high-gainpentagrid secondmixer. The 9.0015
mc energy from Vt, coupled to grid # | of Vs,
beatsagainstthe 16.2515mc s.s.b.signalto produce still another s.s.b. signal at a difference
frequencyof 7.25 mc. As you can see,we have
arrived back at the original transmitter frequency. Instead of a carrier, though, we now
have s.s.b.,minus carrier.
Two 6AG7 r.f. amplifiers, wiled in parallel,
amplify this s.s.b.energy sufficientlyto drive a
transmitting tetrode biasedfor AB1 linear operation. Output is more than adequate for two
6 1 4 6 ' so r a n 8 1 3 .
An interesting characteristic of this unit is
that no matter what crystal frequency is employed at V1, the frequency of the suppressed
carrier at the output of the adapter will be e,rnctly the same as that of the transmitter carrier
fed into Z;. Consequently,
any slightdrift rvhicb
may occur in the 6C4 oscillatorcan have absolutelyno effecton the transmittedfrequency.
-l-his
meansthat the generateds.s.b.signal has
exactly the same degreeof frequencystability
as the a.m. or c.w. transmitterto which it is
connected,becausewhatever we add in V;, we
subtract in Z6 or vice-versa.

Construction
Chassis dimensions are 3" X 15" X 8r/2"
The front panel is \Vz" wide and 9" high.
Shields,3" X 7V2", cut from sheetaluminum
are installed betweenstagesas illustrated in the
photographs.The shieldsare placed41/+",77a"
and 9/2" from the chassisfront. An 8/+" X
143/+"botlom olate should also be used.
The shield betweenthe input and output terminals of the Mccoy filter is especiallyimportant, since any unwanted energy that sneaks
around the filter will degradeits -55 db attenuation spec.
Trimmer capacitor C3 comes into use only
when ,Sr is thrown to the ruNr, position. It provides extra capacity to pad the frequency of Y2
down to exactly 9 mc, right in the middle of the
filter's passband.At the same time, another section of 51 grounds pin I of 22, unbalancingthe
tube and preventing suppressionof the 9 mc
signal from Zr. This arrangementallows plenty
of carrier to reach the following stages of the
adapter and transmitter for tuning purposes.
With this arrangementyou don't have to whistle
in the mike or utilize an audio tone generator
when peaking and loading the final.
Do not change the indicated capacitor values
associatedwith T1 and 72. If you do, the filter
will be improperly terminatedand humps will
appearin its passbandcurve. The two unmarked
capacitorsshown outsidethe shieldsof Ir and
ft are suppliedconnectedto the transformers
and shouldbe rewiredas shown.

holes large enough to accommodatethe shaft
and support rods in the other two shieldsthrough

The SB-8 may now be aligned for the higher
frequency bands following the procedure outlined in Table I. At 40 meters,a certain amount
of residual carrier will appear in M1 no matter
how you adjust Co and Lc. This effect is due to
the broad band characteristicof 111 which allows a small amount of 9 mc energy to reach

can also be usedon the I I meter Citizen Band.
The mode of operationmay be chosenwith a

power supplyis also included.

the Model HE-73 will proAs a pre-selector,
vide additionalr.f. anrplificationfor a receiver,
resulting in increasedgain and sensitivity.In
many casesit also will better the overall signalto-noise ratio of the receiving system. Besides
this, it will add front-end r.f. selectivity and
thereby inrprove i.f. image rejection. This is an
especiallydesirablefeature for single-conversion
receiverswhich use a low-frequencyi.f. system.
With recciverswhich do not have an r.f. stage
ahead of the first n-rixer,the use of the HE-73
not only will improve the r.f. selectivityand i.f.
image rejection. but will also increasethe sensitivity considerably.
Referring to the block diagram, fig. 1A, high
gain is obtained by the use of two stages of
r.f. amplification, while the desirableselectivity
characteristicsare obtained with a high-Q r.f.
circuit in each stage, both of which are gangtuned from the front panel to peak up the signal.
A 68A6 pentode,21, is used in the first r.f.
stageand the pentodesectionof a 6BL8, Z:r, in
the second stage. (The triode section of the

Crystol-ControlledConverter
When used as a crystal-controlled
converter,
the HE-73 will make a sensitivedouble-conversion system out of a single-conversionreceiver
for use on the 10, l5 and 20 meterbands.High
signal-to-noiseratio with excellent image rejection will be realized and it will make possiblea
higherdegreeof frequencystabilitythan usually
is experiencedon these bands with many receivers.Also, it will extend the frequency range
of receiverswhich have limited coverage.
A block diagram of the converter arrangement is shown in fig. 18. /:. is now used as a
pentodemixer insteadof a straight-throughr.f.

for the 10, 15 and 20 meter bandsrespectively.
When the converteris usedfor 10, it's output
frequenciesfall in the 3.5 to 5.2 mc range over
which the receivermust then be tuned.On 15 the
tuning rangeis from 3.5 to 3.95 mc. and on 20
metersit is from 3.5 to 3.85 mc. These ranges
are directly marked on the panel of the Precon.
The actual receivedfrequency may be deternrined by addingthe frequencyindicatedon the
receiver'sdial to the heterodyningfrequencyfor
the band in use. For example: A receiverdial

An RTTY Audio Oscillcrtor
Modifying An Inexpensive Commerciql Kit
BY BYRON H. KRETZMAN'I., W2JTP
r had a problem. A good variable frequency audio oscillator was needed.
Specifically, we needed something to
cover the range from about 800 cycles to 5000
cycles.These are the audio frequenciesof prime
interestto the RTTYer, and to the v.h.f. (f.m.)
operator who is experimentingwith tones and
filters for remote control purposes. Available
kit-type audio oscillators are mostly sine and
squarewave generatorscovering wide frequency
ranges.Besidesbeing more than necessary,and
expensive, for our purposes, their dials are
crowded over the frequency range in which we
are most interested.This makes it difficult to
resetto a particular frequencywith a reasonable
amount of accuracy.
The solution was to build an audio generator.

Modifying the Heqthkit lT-12
Looking over the IT-i2 SignalTracer, it immediatelybecameobviousthat, to find room for
the dual sectionbroadcast-typevariablecapacitor
requiredfor the oscillator,the speakerhad to go.
The next considerationwas the dial. The National Type BMI ($1.10from Barry Electronics)
proved to be exactly the right size. It covers the
speakerhole and easily mounts by drilling only
three small holes. The dual section tuning capacitor, which must be insulated from the
chassis,was mounted on a bakelite plate stood
off from the chassisby two metal pillars. The
audio output transformer which formerly
mounted on the speakerwas found to fit nicely
under the tuning capacitor.
The tuning eye tube and its bracket was next
to go. The hole for the tuning eye tllrned out to
be the right size openingfor a 1tlz-inchsquare

PM-LV2 miniature speaker. (Who needshi-fi?)
The flocked speaker grill was cut down to fit.
One of the holes in the chassisfor the tuning eye
bracket provided the center for draw-punching
(with a GreenleeNo. 730 SocketPunch) a %
inch hole for a nine pin socket for the 12AU7
audio oscillator.
Other incidental modificationswere to replace
the rotary a.c. line switch with a 500 ohm pot
(with switch) to control the output of the oscillator, disconnectionof the binding posts from
the signal tracer output transformer; and, installation of a speakerjack and an input jack

for the probe. The red

The panel switch marked NoISEwas disconnected from the probe circuit and wired as a
B-plus oN-oEnswitch for the oscillator.Incidentally, the filter capacitor was dropped below the
chassisby a couple of 3/q-inchlong metal pillars
to enable the tuning capacitor rotor plates to
clear.
The OscillotorCircuit
Fig. one shows the schematicdiagram of the

to make the output uniform over the full range

that 30 mmf kept the output within 0.5 db over
the entire range. Open circuit output of the os'
cillator is *3 dbm.
Figure two shows the minor circuit modifications of the signal tracer itself, made mainly to
add feedback.
Cqlibrotion
Before beginningcalibration,a v.t.v.m. (a.c')
should be connected to the output terminals,
and capacitor C adjusted so that the output is
as constant as possible.Since listening to what
you are doing is the purposeof the signal tracer,
output from the signal generator is coupled-in
by simply connectinga 100K resistorbetweenthe
two red binding posts. Calibration was done by
also coupling-in the output from a 425 cycle
tuning fork standard,actually the one described
in Chapter7 of the New RTTY Handbook.By
adjustingthe relative levelsof the two oscillators
by means of the panel gain controls, it is very
easy to hear the beat notes betweenthe tunable
audio oscillator and harmonics from the fork
standard. A calibration point then is recorded
every 425 cycles.On the low end of the scale,additional beat notes may be heard from 3-times

The antenna works on the principle that a

present an almost infinite impedance to radio
frequency current at that particular frequency.

pass through the trap almost as though it were

can be taken advantage of to build an antenna
with an overall length of only 108 feet which
will give almost as good performance on 75 as
a fttll /z wave doublet, as well as being very
good on the higher bands. Twenty meters gives
a higher s.w,r. but for l0 and 15 the s.w.r. is

immediately noticesa very prominent landmark.
A black painted ship'smast completewith crow's
nest and rigging. It stands near the end of the
ilon-pile jetty, and as I was to discoverlater, is
almost 70 feet high. A somewhat melancholy
reminder, no doubt, of a disasterwhich occurred
many years ago in the breakers-but, quite
naturally, the only thought which crossed my
mind at that moment was, what a gift for a
ham's antennal

I entered the anchorageslowly until I could
discernthrough the crystal clear water the white
sand and seaweedon the bottom. Then I let go
in 5 fathoms. Even though close up to land, as
close as I dare go, the ocean swells passingthe
protecting horns of the reefs to the north and
south of us. meeting in the midst of the anchorage in the form of uneasy mounds of water,
causedour small vesselto roll and pitch. I could
see at a glance that during bad weather-especially with the wind, anything west of southour position would becomeuntenable.
Shorewards,all along the edge of the reef the
swell broke in a smother of foam on jagged
coral. The moment hardly seemedfit for a landing; nevertheless,I hadn't time to lose, The boys
were all waiting for VQ8BFA, and moreover the
weather might deteriorate at almost any time.
I therefore decided to launch the pirogue and
proceedashore.
It was half tide. Near the entranceto the channel we found that we had to contend with the
fierce current still pouring out from the lagoon.
Soon heavy breakers foamed over the coral on
both sidesof us. We were now strugglingin the
midst of alarming rip tide. Suddenly a huge hissing breaker reared up astern,and gathering the
pirogue on its back, surf-boarded us into the
channel at a fierce speed,Then there was an appalling crash; a vast smother of water amidst
which the pirogue broached-to.We lay almost
on our beam on the back of a huge slantingcoral
head where, as the wave receded,we were left
momentarily high and dry. Realizing in a flash
that there was no seriousdamage;that the next
comber might fill us, capsizeus, and so perhaps
finish us all, we leapt from the boat onto the
rock and into the surge,and managedby frantic
shoving to slide the pirogue off just in the nick
of time before the next breaker arrived.
VQSBFA had started off somewhat inauspiciously; and this experience was more than
enoughto convinceme that no attempt shouldbe
made to land any heavy equipment until the
weather moderated.I therefore decidedto await
more favourable conditions, at the turn of the
tide, and eventhen, only to ferry ashorethe small
battery rig that day.
OperotionsBegin
Fortunately there were no more setbacks'And
by 1500hours crar the rig had beensetup ashore
in a small shack convenientlyplaced at the edge
of the beach, and kindly put at my disposalby
the Administrator.
I supposethat most hams will find the rig rudimentary. The transmitter, an old TCS-12, converted to bring it on to the 20 meter band by the
simple process of peaking up the v.f.o. inductance;broad-bandingthe v.f.o. and buffer-doubler
plate inductors; and modifying the p.a. output
and antenna-couplingcircuits. In this instancea
132 foot long wire was brought down to the
shackfrom the 70 foot ship'smast, alreadymentioned.This was end fed, being simply clipped on
to the p.a. tank. The astenna was orientatedin

an east-westdirection. (Needlessto say, no TVI
or other similar problems existed). Power was
suppliedfrom 12 volt accumulatorsthrough conventional dynamotorsfor both the transmitter
and receiver.
The big snag about this set-upwas that in order to avoid continuousdemandson the batteries,
the tx could only be left switched on during actual periods of transmission.Hence, when the
band was open and speedy operation essential,
many preciousminutes were lost waiting for the
tx heaters to warm up. Again, under these circumstances,the tx could never be worked at its
optimum temperatureand this of courseresulted
in considerablefrequency drift. (A11 this was
later corrected by separatingthe heater circuit
and runningit off a separatebattery'The heaters
rverethen left on continuously,and only the Bplus power was cut during receive.)But there remained still one other difficulty; owing to the
rough weather, no battery charger had yet been
landed.We had to ferry all the batteriesonboard
lhe Mctrsottinevery morning for re-charging,and
back ashoreagain later in the day. This deiay was
responsiblefor the loss of a considerableamount
of operating time.
So at 1505cMT, the day of our arrival at Agalega, I switched on and VQ8BFA was on the
air. A thrill of expectationran right through me,
even to my finger tips, as I tapped out the first
cQ.

the other hand, certain proposals, although not
clear in their intent. appeared to be sttbject to
the interpretation that space activities would be
prohibited for services which have not been
specifically allocated any frequencies for space
communcations. The conference began, therefore, with the possibility that amateur-radio activity in space might not be permitted in the

Perhaps as a move to avoid any misinterpretation that might result in prohibiting space

position to the proposed British allocation was
such that no headwaycould be made. It became
obvious that the conferencerequired a briefing
on the accomplishmentsof amateur radio in th!
field of spacecommunications,and plans for the
future. The chairman of Working Group 5C
called a temporary halt to the diicussion and
requestedthat the IARU submit a briefing paper
to the conferenceon this subject.This in^itself
can be consideredas an important milestonefor
amateur radio in the international field, since it
was the first time since the days of Hiram percy
Maxim that the IARU had been invited to narticipateactivelyin the deliberationsof an international conference!
Fortunately, the IARU delegationcame well
prepared wilh reports, articles, photographs,
letters, etc. describingin detail the-Oscli ama_
teur radio satellite program. The ,,night oil,'
burned brightly in severalhotel rooms in-Geneva
until the wee hours of the morning as the IARU
representatives summarized the Oscen data
into an official conferencedocument.The document, bearing the number Doc. g4, and entitled.
"Oscen

nationalAmateur Radio Union," was circulated
to the conferenceon October 14.
Coincidentally [?], a model of the Oscrn
beacon satellite was in Ceneva at the time. and
was immediately put on exhibition at the Con_
ferencelocation. This enabledskepticaldelegates
to see and handle the satellite themselves.
On October 12, the chairman of Workins
Group 5C appointedan atl-ltocgroupcomprisin!
delegatesfrom Canada, the USA, the UK and
the USSR to try to break the deadlock. It aopearsas if the IARU documentand the Oscan
exhibit helped accomplishthis, since a few days
later..the ad-hoc group proposed the following
wording which subsequentlywas found to be

taking into account the desire of amateurs to
use space satellites for amaleur communications and in
light of any recommendation received from the Interna_
tional Amateur Radio Union, the conference resolves
that the CCIR be requested to study and recommend
upon the technical principles on the basis of which such
use of satellites can be conducted taking into account
the use of the band concerned by normal Grrestrial ama_
teur radio operations,',
During the course of discussionon this oroposal. it again became apparent that furiher
information concerningamateur radio had to be
supplied to the conference.On October 29, the
IARU submitted its second official conference
document. This document, number Doc. 107
Rev., describeshow amateurshave handled the
problem of interference in the amateur bands
without requiring regulatory assistance, and
answeredseveraladditionalquestionsthat were
raised in previous discussionson the conference
floor. The document also called attention to the
Union'sdesireto havea segmentof the 10 meter
band allocatedfor radio amateurspaceactivities.

(The
CCIR is the technical area of the ITU and is
responsiblefor studying technical questions of
an international level in the field of communications).
At a full Committee 5 meeting on November
2, amateur radio was again the subject of long
and heated debate. At this meeting, however,
a majority of nations approved Document 95
and agreedto deletethe resolution to the CCIR.
Privately, many delegatesstated that thev took
this action as a result of the information made
available by the IARU in Document 107. The
Committeedid not approvea l0 meter allocation
ror amateur spacecommunicationson the basis
that no experimentshad as yet been carried out
in this band, and there was no evidencethat anv
were being planned for the future.
On November 5, Document 95 moved into
the Plenary Assembly of the conference,where
delegatesfrom 70 countriesconvenedto discuss
it. The Plenary meeting approvedDocument 95,
but shortenedit to read as follows:
"In the
band 144-146 mc, artificial satellites may be
used by the Amateur Senice."
.. The Plenary dropped the original wording,

amateurradio:
1. The amateurradio servicereceiveda worldwide allocation, on an exclusivebasis,for space

great majority of nations to the side of amateur
radio.
ln these days of controversy over the future
of amateur radio, it is encouragingto note that
nationswill still lend support to the experimental
and comntunication aspectsof this service,and
that an organization is available to represent
these interests on a worldwide, international

line each
conductor is at high potential with respect to
ground, thus creating high currents which florv
in opposite directions in each conductor. This
high current flow would normally cause the
feedlineto act as an antenna.but. the conductors
are spacedclose enough so that any radiation is
cancelled.
The situation is different with coaxial feedline.
the inner conductor being at high potential with
respectto the outer conductorwhich is grounded.
Matching this type of uttbalancedtransmission
line to a balancedline (or antenna) cennot be
accomplishedsimply by connectingto the coax.
Assumingequal surgeimpedancesfor both lines,
currents from the balancedline will flow on the
outer conductor of the coax causingradiation. A
proper connectioncan be achieved.however, by
using a "line balanceconverter" or balun.
The purpose of the balun is to increase the
impedance of the outer conductor to prevent
r.f. from flowing over it. The balun is essentially
a quarter-waveIine acting as a metallic insulator.
This shorted, quart€r-wave line will exhibit
standingwaves when the open end is resonated.
At the shorted end. a voltage node (minimum)
and current loop (maximum) occurs and at the
open end, a voltage loop and current node occurs. Thus, an extremely high impedanceexists
at the open terminals and the line acts as a
quarter-waveinsulator. The vector sum of any
unbalancedcurrentsat the antennaterminalswill
be zero at the shorted end of the stub thus preventing these currents from flowing into thc
remainderof the line.
Although the balun is limited to a narrow
bandwidth, it tends to stabilize the existing impedancevalues.The explanationof this fact is
that the equivalentcircuit for a shorted line less
than a quarter wave in length is inductive.Should
the transmitting frequency be slightly less than
resonant,the antennareactancewould be capacitive. The balun would then tend to maintain the
existing impedancevalue by inductively cancel+19265 Santa Rita Street, Tarzana, Calif.

ling out the capacitivereactance.Similarly, the
equivalent circuit for a shorted line more than
a quarter wave in length is capacitive.With a
transmitting frequency slightly above resonance,
the antenna reactanceis inductive. The balun
would then tend to maintain the existing impedancevalue by capacitivelycancellingout the
inductive reactance.
A type of balun pertaining to coaxial lines is
the detuning sleeveor bazooka.This. essentially,
forms a secondarycoaxial systemwith the sleeve
acting as the outer conductor and the outer conductor of the coaxial line as the inner conductor.
The balun shown in fig. 1, made with coaxial
cable. is easier to construct than a sleeve.
The quarter wavelengthcan be determinedby
formula:

J<v,)
In constructing the line, however, a recommended practical approach is to cut the line
several incheslonger than the formula indicates
and then to resonate the line with a grid-dip
oscillator before connection is made to the antenna. The g.d.o. should be coupled to the
shorted end while equal small lengths of outer
conductor braid are cut from both open ends
(leaving sufficient inner conductor for antenna
connection) until resonanceis determined.The
procedureis tedious,but don't rush through it. I

-f lf you can beg, borrow or steala coil set for
any HRO from the HRO Jr. on up, you can
wind your own. Try to get a set with two trimmers mounted on each coil board. The set I
converted had only one trimmer and made the
job of alignment more tedious and involved
extra work. Figure I shows a pictorial of the
finished product.
Preporotionof Coil-set
Clean out the coil set carefully leaving all
the air trimmers. If there are two air trimmers
in the r.f. and oscillator sectionsin your coil set,
remove plates from one of them to brine it
down to a 5 to 15 mmf range.
If there are U shapedhandleson the coil-set
they have to be removed and replaced with a
bolt and sleevearrangementsimilar to the other
HRO-60 coil sets.

completing the antenna section the two r.f. sections should be tackled. If the coil set used has
two air trimmers the layout will have to be
slightly different than shown in fig. 1. Fabricate
and assemblethe coils and wire them in. Now
mount the 3-12 mmf NPO ceramic trimmers on
stiff wire leadsand position them in such a manner so you can reach the adjustment screws
through the front of the coil can for alignment
purposes.
The oscillator sectionmust have a hole cut in
the back of the shield can so that the double
conversion stage will operate. Check the 20
meter coil set and notice the position of the hole.
Placea pieceof paper on the rear of the 20 meter
oscillator coil and rub your finger over it to get
an impressionto use as a template. Need I tell
you to drill the 15 meter oscillator cover without the coil in it? Install the oscillator coil and
the 3-12 mmf NPO ceramictrimmer on stiff wire
and position it so that it can be adiustedfrom the
front.
Coil Preporotion
The coils are prepared from two lengths of
Miniductor stock. A length of #3003 is used
for the primaries and a length of #3011 makes
up the secondary windings. When cutting the
coil sections as listed in the chart be sure to
allow enough additional turns to peel ofi connectingleads.
The construction is simple since the primary
windings are insertedin the secondarywindings
and held in place with a few drops of glue placed
at strategicpoints. The coils are self supporting

To begin the alignment I used a signai generator to get as close as possibleto the desired
frequency. After that I used the transmitter

large air trimmer sets the overall range and its

When the alignment is complete mount all

is not placed on the finger contacts in the receiver. If you break one off, you have a real job

SunspotCycle
The SwissFederalSolar Observatoryat Zurich
reportsmonthly mean sunspotnumbersof 4l for
September
and 36 for October,1963.This results
in smoothedsunspotnumbers of 30 centeredon
March and 29 centeredon April, 1963.The sunspot cycle has remainedpracticallyconstantfrom
October,1962throughApril, 1963,droppingless
than 2 numbersduring this sevenmonth period.
A smoothed sunspot number of 16 is predicted
for January,I 964.
Next month's column will contain a detailed
analysis of the present sunspot cycle, including
predictionsfor its remainingmonths, and for the
beginningof the new cycle.
I963 ln Review
The past year marked the ninth of the present
sunspot cycle, which began during April, 1954,
and reacheda peak during March. 1958.Sunspot
activitycontinuedto declineduring 1963,but at
a slower rate than during previous years.
1he year beganwith a smoothedsunspotnumber of 30, and by December, solar activity had
decreased to an estimated smoothed sunsDot
l e v e lo f 1 8 .S u n s p oat c t i v i t yd u r i n g 1 9 6 3* u . i p proximately one-third lower than the level recorded during 1962,and was the lowest recorded
since 1955. Propagationconditions observedon
the h.f. amateur radio bands were typical for a
period of low solar activity.
DX propagationconditionson the 10. 15 and
20 meters bands were adverselyaffectedby reducedsolar activity during the pastyear.Except
for an occasionalnorth-southDX openingduring
the daylight hours, DX propagation was not
possibleon l0 meters.Fifteen meter DX openings were also noticeablyfewer during 1963 as
compared to previous years. Often, when the
band did open, it was usually for much shorter
periodsof time and to fewer areasof the world
than during periodsof higher solar activity.
DX propagationconditions on 20 meters also
becamepoorer during 1963,but to a lesserdegree than on 10 and 15 meters.Despitea considerablereduction in late afternoon and early
evening openings,the band, however, did open
to many areasof the world during the daylight
hours.Twenty meterswas the optimum band for
DX during 1963 from shortly after sunrise
through the late afternoon hours.

Jcnuory, 1964
While a weaker ionosphereresultedin poorer
DX propagation conditions on 10, 15 and 20
metersduring the past year, conditionson 40, 80
and 160 metersimproved considerably.This improvement resulted from a marked decreasein
ionosphericabsorption associatedwith a weaker
ionosphereand lower solar activity. Signals,both
DX and short-skip.were noticeably stronger on
40 meters,and the band openedmore frequently
for DX, and to more areasof the world than during previous years, In fact, 40 meters was the
optimum band for DX during the hours of darknessduring the pastyear. A similar improvement,
although not as outstandingas on 40 meters,also
was observedon 80 meters.
The most noticeableimprovement in propagation conditionsduring 1963,at leaston a relative
basis,took place in the 160 meter band. During
periods of high solar activity, this band is generally limited to short-skipopeningsof no more
than severalhundred miles during the hours of
darkness. During the past year, however, the
band beganto open regularly for DX as early as
the first days of September,and continued to
open for DX more often, and to more areas of
the world than had ever occurred previously.
Considerablyfewer ionosphericopeningstook
placeon the v.h.f. bandsduring 1963.This probably results from a marked decreasein auroral
displays associatedwith the reduction in solar
activity. On the other hand, Morgan and Dorothy
Monroel report a continuedincreasein the number of Sporadic-Eshort-skipopeningswhich occurred during the spring and summer months of
the past year. This adds further evidenceto the
theory that Sporadic-Epropagationincreasesas
the solar cycle declines.
High frequency, or shortwave, propagation
conditionsduring 1963were, therefore,generally
poorer on 10, 15 and 20 meters, and improved
on 40, 80 and 160 meters.There was a greater
amount of Sporadic-E propagation, but fewer
v.h.f. ionosphericopeningsduring the year.
O u t l o o k1 9 6 4
The sunspot cycle is expectedto continue its
declineduring 1964,and the year will be marked
by a period of low solar activity. This is expected
to result in a further decreasein the number of
10, 1-5and 20 meter DX openings.Except for an
occasionalopening during the daylight areasto
southernor tropical regions,DX openingson 10
metersare consideredto be unlikely during 1964.
Somewhat fewer DX openings are expectedon
15 meters during the new year, but openings
should be possibleto many areas of the world
during the late fall. rvinter and early spring
months. When 15 meter openingsdo take place,
they will most likely occur during relatively short
periodsof time from a few hours before noon to
a few hours after noon. Not much changeis expectedin 20 meterpropagationconditionsduring

1964.Although there may be fewer DX openings,
the band is still forecast to open to almost all
areas of the world between the sunrise period
and the early afternoon hours. Twenty meters is
expectedto be the best band for DX during the
hours of daylight, and through the early evening
hours of the summer months.
On the other hand, DX conditionsare expected
to continuetoimprove on 40, 80 and 160 meters.
The improvementon 40 metersis expectedto be
slight, and for the most part, propagationconditions on this band are expectedto be similar to
what they were during 1963.Forty metersis expected to remain the best band for DX during
the early eveninghours of the fall, winter and
spring months, and during the hours of darkness
in the summer season.A considerableimprovement is expectedin DX propagation conditions
on 80 meters. This improvement has already
been noted during the last months of 1963,
and it is expectedto continue during the new
year. DX openingsare expectedto be more numerous on this band than ever before, and signal
levelsare forecast to be unusually strong dLrring

The schedulefor the FrenchContesthas been
changed this year and thesedates will probably
be retained for future contests.Unfortunately
the c.w. sectioncoincideswjth our 160 contest;
this is going to cost them someactivity as many
contest minded operators will be concentrating
on the top band.
Rules are practically the same as previous
years with one exception. The multiplier will
now be determinedby the numberof French departments worked on each band. (Previously
the provincewas usedas a multiplier,a confusino
qrrcnoemenf
)
l. The usual serial numbers,RST or RS report plus a progressive
3 digit QSO numberstarting with 001.
2. French stationswill give their Department

the clock in the old town of Genevastruck
midnight on November 8, a new era in
communicationsbegan.At that moment,
representativesfrom the last of the 70 nations
attendingthe SpaceCommunicationsConference
of the International Telecommunication Union
aflflxedtheir signaturesto the Final Acts of the
Conference.The Final Acts contain the results
of this five week conferencewhich succeededin
allocating frequencies,for the first time, to the
various spacecommunication services.On January 1.,1965,the Final Acts will officially become
a part of the International Radio Regulations.
the basic document governing the operation of
radio throughout the world. The Radio Regulations have the status of an international treaty
so far as the United Statesand most other countries of the world are concerned.
Every spacesatelliteor spacevehiclelaunched,
whatever its purpose, is dependent upon communicationsfor its link with the earth. The conference, attended by more than 400 scientists,
engineers and government officials from 70
countries, discussed all facets of radiocommunication between earth and space, and between space vehicles. After five weeks of discussion and negotiation. the conferenceagreed
to allocatefrequencybandsin the crowded radio
spectrumto servespacecommunicationrequirements for at least the next generation.A total of
nearly 6,100 mc have been allocated for the
various kinds of spacecommunicationservicesin
discretebandsbetween10 mc and 35.2gc (a gc,
or gigacycleis equivalentto 1,000mc). The successof the conferencehas beenhailed by experts
as a great step toward the eventualdevelopment
of communication. weather and navigational
satellitesystems,as well as permitting expanded
spaceresearchand exploration,both mannedand
unmanned.

radio amateurs will be able to here signals from satellites launched in the future. It is expected that satellites
launched by the United States will make greatest us of
the bands 136-137 mc and 137-138 mc. while satellites
launched by the USSR will make greatest use of the h.f.
bands and the band L43.G143.65 mc, for telemetering

Spoce Definitions
In addition to the above listed frequency allocations, the conferenceadopted a number of
important definitions, resolutions and recommendations.The following is a partial listing of
the definitions agreed to internationally at the
conference.
Space service-A radiocommunication service between
earth stations and space stations, or between space stations, or between earth stations when the signals are
re-transmitted by space stations, or retransmitted by reflection from objects in space, excluding reflection or
scattering by the ionosphere or within the earth'satmosphere.
Earth station-A station in the space service located
either on the earth's surface, including on board a ship,
or on board an aircraft.
Space station-A station in the space service locatcd on
an object which is beyond, is intended to go beyond, or
has been beyond, llre major portion of the earth's aimosphere.
SDacesystem-Any group of co-operating earth and spacc
stations, providing a given space service and which, in
certain cases, may use objects in space for the reflection
o f t h e r a d i o - c o m m u n i c a t i o ns i g n a l s .
Communication satellite servic€-A space service between
c a r t h s t a t i o n s , w h e n u s i n g a c t i v e o r p a s s i v es a t e l l i t e sf o r
rhe exchange of communications of the fixed or mobile
service, or between an earth station and stations on active satellites for the exchange of communications of the
mobile service, with a view to their retransmission to or
from stationsin the mobile scrvice.
Communication-satellite
earth station-An
earth station
i n t h e c o m m u n i c a l i o n - s a r e l l i l es e r v i c e .
Communication-satellite
spac€ station-A
space station
in the communication-satellite service, on an earth satelIi t e .
Active satellite-An earth satellite carrying a station intended to transmit or re-transmit radiocommunication
signals.
Passive satellite-An earth satellite intended to transmit
radiocommunication signals by reflection.
Sat€llite system-Any group of co-operating stations providing a given space service and including one or more
active or passive satellites.
Space ressarch seryic€-A space service in which spacecralt or other obiects in space are used for scientific
or technological research putposes.
Broadcasting-satellite service-A space service in which
signals transmitted or retransmitted by space stations,
or transmitted by reflection from objects in orbit around
the earth. are intende.d for direct rec€ption by the general public.
Radionavigation-satellit€ service-A service using space
stations on earth satellites for the putpose of radionayigation, including, in certain cases, transmission or
transmission of supplementary information necessary for
the operation of the radio navigation system.
Mcteorological-satellit€ s€rvice-A space service in which
t h e r e s u l t s o f m e t e o r o l o g i c a l o b s e r v a t i o n s ,m a d e b y i n struments on earth satellites, are transmitted to earth
stationsby space stationson these satellites.
Space telemet€ring-The use of telemetering for the transmission from a space station of results of measurements
made in a spacecraft, including those relating to the
functioning of the spacecraft.
Maintenance space telemetering-Space telemetering relating exclusively to the electrical and mechanical condition of a spacecraft and its equipment together with the
condition of the enyironment of the spacecraft.
Space tel€command-The use of radio:o:nmi nication for
the transmission of signals to a space station to initiate,
modify or terminate functions oi the equipment on a
space object, including the space station.
Space tracking-Determination
of the orbit, velocity or
instantaneous position of an object in space by means of
radiodetermination, excluding primary radar, for the purpose of following the movement of the object.
Deep space-Space at distances from the Earth equal to
or greater than the distance between the Earth and the
Moon.
Orbit-The path in space described by the enter of mass
of a satellite or other object in space.
Angle of inclination of an orbit-The
acute angle (less
than 90 degrees) between the plane containing an orbit
and the plane of the earth's equator.
Period of an object in space-The time elapsing between
two consecutive passages of an object in space through
the same point on a closed orbit.
Altitude of the apogee-Altitude above the surface of
the Earth of the point on a closed orbit, where a satellite is at its maximum distance from the center of the
E ar t h .
Altitude of the perige€-Altitude above the surface of
the Earth of the point on a closed orbit, where a satellite is at its minimum distance from the center of the
Earth.
Stationary satellite-A satellite, rhe circular orbit of
which lies in the plane of the earth's equator and which
lurns about the polar axis of the Earth in the same
direction and with the same period as that of the earth's
IOtatlon.
Spacecraft-Any type of space vehicle, including earth
satellites, deep space probes, whether manned or unmanned.
One of several important amendmentsto the
Radio Regulations adopted by the conference
deals with ceasing radio transmissions fron"r
satellites.The amendmentstatesthat "spacestations shali be made capable of ceasing radio
emissionsby the use of appropriatedevicesthat
will ensure definite cessationof emissions(battery life, timing devices,ground control, elc.)."
The conference also approved technical standards and criteria permitting space services to
share most of its frequency allocationswith existing terrestrial communication services.This
was accomplishedby agreeingto limit the signal
strengththat certain spacestationscan deliver on
the Earth, and by setting up "coordination distances"within which countriesmust coordinate
their space communicationactivitieswith terrestrial communication activities in order to
ensurethat interferencewill not occur to either
communicationactivity.

Both Sides Of The Coln
The most controversialissueever facing ama_
teur radio operatorsin the U.S. was thrJwn in
the hopper when the Leaguepetitioned the FCC
for a Rule change (RM-499) covering both
licensecategories,restrictions,special privileges
and re-allocationof band usage,under the guise
of "License Incentive."
A major reasonfor the bitter controversyhad
nothing to do with "License Incentive" but resulted from the drastic approach by ARRL and
their failure to honestly state their political
motives.
On November 9th, 1963, the writer debated
this controversialissuewith First Vice president
of ARRL, Wayland (Soupy; Groves,W5NW,
for three hoirrs before the annual Texas SwaoFest held at Brownfield,Texas. Folks from all
over Texas came to Brownfield seekinganswers

The cathodeleadsfor the 2E26 shouldbe made
with a copperstrap betweenpins 1-4-6and connected by another copper strap to the chassis
with as short a lead as possible;this is important
-many casesof TVI have been traced to this
spot.Disc ceramiccapacitorsshould be usedto
provide low inductance bypass paths. Coils
should be resonatedwith a grid dip meter and
may be wound on any availablecoil form. The
coil data given may not hit the band with the
coil forms that you have, but is given as "bail
park" data.
Modulator wiring should also be kept sholt
and routedas far as possiblefrom the r.f. wiring
to prevent feedback.lt is a good idea to use
shieldedwire for all low level audio wiring.
Use a cleansolderingiron and keepall solder
joints free of dust and filings. Use enoughheat
to effect a good bond and be sure that all joints
are electricallyperfect.Cold solder joints are
the causeof many transmitter'snot delivering
their maximum power olltput.
I have not had to neutralrzeany of the transrnittersthat I have built, but if your transmitter

any of the popular methodsof neutralization.I
think that one possiblereason I've had little

amplifiers; attenuation of spurious signals;harmonic distortion; intermodulation,and oscillation.
Commercial manufacturersutilize tubes having fairly high gain and low noisecharacteristics'
Usually, the first stages(amplifiers) are triodes
but the succeedingisolation stagesare pentodes
with the suppressortied to the cathode to give
more stability.
Actually, by substitutingtunedcircuitsfor the
broadband fixed tuned circuits, it is possibleto
use the multicoupler as a preselector-amplifier.
However, if high gain tubes are used,there is
alwaysa possibility(if care is not taken in isolating input and ouput circuits) of oscillation.
Of course,commercially available multicouplers are out of the price reach of the average
ham. Furthermore, they are generally designed
for up to at least six outputs.
receiversare connecteddirectly (in tandem) to
an antenna. The overall gain of both sets was
appreciably higher on 7 and 2l mc than it was
on the other bands. However. the lower noise
and increasedgain on 10 meters was well worth
the effort putting the coupler together.
Note that the grids of the 7587 isolationamplifiers are in parallel, while their plate circuits are
isolated from each other. Perhaps pentodesin
these stageswould make for better isolation. If
you decide to try pentodes,be certain that the
suppressorgrid is connectedto the cathode and
that you use all of the isolation resistorsshown.
HowNeutralizationwas found unnecessary.
ever,if you run into oscillation,any of the usual
neutralizationmethodsnormally used in transmitter stageswill work.
If additional receiversare used, all you need
do is to duplicatethe last isolationstagefor each
extra set. Just make sure that you have the required filament and plate power for the extra
tubes available.
You can try tuning the secondaryof the antenna input coil assembly for added gain by
paralleling it with a variable capacitor of 250
mmf on 3.5 mc to about 50 mmf on 28 mc.
Make certain that your inputs and outputs of the
coupler are isolated mechanically so that there
will be no feedback.
The input of this unit was roughly designed
for 72 ohms. but if you wish to changeto some
other value, the link may be modified accordingly.
If your receivershave different input impedances,yor-lcan modify the coils in the outptlts

personal friendships out of these DX contacts,

Unit Types
These surplus units are found in both single
and double coupler types. The single coupler
type will respond only to incident power and
will produce a full scale deflection on an appropriatemeter and multiplier from 1.2 to 1200
watts. The double coupler types are really two
single directional couplers built together with
one adjusted to respond to incident power and
the other to reflectedpower.
The incident and reflectedpower pick ups in
the couplerare fed to connectorswhich contain
type 1N21 crystals.These rectify the r.f. and
the d.c. voltagesare fed to the indicator unit
which may be placed at any remote point.
Functions

can be determinedby the differencein the readings betweenthe incident and reflectedpowers.
The single couplers can only monitor the incident power to the load which will differ from
the net power by about ten per cent for an s.w.r.
of up to 2:1.

the meter was calibrated full scale for a known
power in the ronweno position. For example,if
the full scalereadingwas producedby 100 watts
in the ronweno position, a quarter scalereading
in the reverseposition indicatesa reflectedpower
of 25 watts. This means that only 75 watts is

the past few yearsthe ranksof the video

then, you ask. is 440 mc not bustling with
strangely buzzing 8 mc wide carriers? The answer is not hard to find.
Interest in amateur television has been around
for years. There are even some stout fellows who
have been orr for years. However, the vast majority preferred to believe that television was too
expensive, too complicated, etc. Many of these
reasons were quite valid at the time. Anyhow,
back in 1957 interest in ham TV started to pick

be a never-ending wave of ups and downs. Some
have even tried to relate these spasmodic pulses
of activity to the I I year solar cycle. This time,
however, things were different. Possibly it was
the advent of commercial TV gear or the flying
spot scanner. alias the B&K analysis. No one
knows for sure, but TV activity has been climbing ever since. Or should we say video activity.
I for one tend to associateamateur TV with a
whole station. and this is just where the prescnt
trend is deficient. Many of the newcomers (ex.
perimenting with the most up-to-date amateur
emission) have tlansmitters and receiverswhich

A lot of fellows are using 416B's or better. I am
sllre many of you have ideas to add to this. Let's
hear from you.
Porobolic Refleclors
We have received several requests for some
elementary parabolic antenna theory. The principle behind the parabolic antenna is really quite
simple. and probably familiar to most amateursi
!et there does seem to be a lot of misunderstanding. The usual way of explaining the dish antenna's operation is in terms of light. When a
light beam shines on a mirror. it is reflectedvery
much in the same way a radio wave is reffected
bl a flat rnetal sutface. The angle of incidence
is equal to the angle of reflection. The sanle effect is true for a t'adio *'ave. A source of light
(a light bulb or a dipole in the case of raclitr
r i , r v e s) e n r i t s l i g h t i n a l l d i r e c t i o n s . C o n s i c l e r
rvhat rvould happen if we ptrt a rnirror behind
o u r l i g h t b u l b b e n t i n s r - t c ha w a y t h a t e v e r y
light ray which hits it would be reflected in the
same direction (see fig. I ). A parabolic reflector
has just such a surface; rvhen a point source of
wave energy is placed at its focal point, parallel
rays should theoretically' be radiated. This case
of infinite gain can. of course, not be met in
actual practice. The biggest stumbling block to
i t s a t t a i n m e n t i s t h e n e c e s s i t yo f a p o i r t t s o u r c e '
Since all radio waves have a finite wavelength'
a point source can never be reached. The divergence of light rays from an auto's headlights
(parabolic reflector) is an example of this fact.
In the radio spcctrum this obstacle bccomeseven
morc pronounced. Howevcr, we do have a way
out. As a pzrrabolicreflector is made larger and
larger, the radiating element will look smaller
and smaller relative to the reflector. or in other
words it will act more and more like a point

feet) is one-quarter of the reflector's diameter.
Not a verl good point source. and the gain
cguation shows-12 db. We might as rvell have
used a plane reflector of the same size! On 431
mc where a half wave dipole is about one tenth
the diameter. a little better approximation is
obtained and a gain of 23 db is possible. If we
go really high in frequencl', values for gain bec o r n e e s t r o n o r n i c a l .O n l 0 k n r c a l 2 f o o t < i i s h

I hope this little refresher-in elernenlarl'
physics clears the air and possible even stirs a
little interest in the parabolic antenna. We plan
to show in the future that a parabolic antenna
is actually not difficult to construct.

same rigs, MA 40624 varactor diode triplers
with 15 watts output and homebrew 70'77 converters-and notes that the 7077 is a very good

Agreed, but we are more interested in those
varactor diodes. Anyone have information on
the MA 4062A'!
We have news of 432 s.s.b. activity in the
California area from another Jim. K6JC. According to him, K6HCP in San Jose is holding
skeds with W6FZA, Porterville. on 432 c.w. and
occasional s.s.b. every Sunday and Tuesday
night at 2200 ps-r. Thus far contacts have been
made alnrost every try with signalspeaking as
high as 53 to .+. A look at the topography will
show a very rough 200 mile path between the

over a 120 nrile path. Conditions over this path
were very good clLrringthe month of August,
however Septenrber proiecl disappointing. We
have had no word of s.s.b. activity from this
group, but rllmors indicate that many 432 t'nc
California stations are contemplating its use.

capacitance bridge; or, if this is not availabie,
a grid dip meter can be used.
If you use a grid dip metet, a 100 mmf mica
capacitor can be connected across the ends of
any convenient coil and the resonant point found
on the grid dipper. The capacitor is then disconnected and the tubular thinwall capacitor is
inserted in its place. By carefully adjusting the
capacitance the same setting on the grid dipper
can be made to dip. During this operation be
sure that you do not have stray hand capacitance
or metal in the immediate vicinity. Otherwise
the setting will be inaccurate and the trap will
be tuned to a wrong frequencY.
After the tubular capacitor has been adjusted
mark the position and drill a hole for a 10-32
screw exactly one inch from each end. These
screws will serve to fix the capacitor to the
dowel and also will be used as terminals for
each end of the indttctor.
To make the inductor gct a piece of 514
enameled wire about 12 to 15 feet long. One
end should be clamped in a vise and the wire
stretched to remove all kinks. Now' using a
cylinder of about 1tr^" in diameter close wind
the entire length of the wire on the cylinder.
When the tension is released the wire will
"
spring out so that it is jrrst under l7z diameter.
A c o i l f o r m o f c l e a r p l a s t i c , l a n - r i n a t e db a k e l i t e ,
or other insulating material 2" long can be used
and 17 turns of the wire are carefully rvorked
over the form, allowing enough on each end to
make connection with the 10-32 screws. These
are uniformiy spaced over exactly lVz" fot an
inductance of 5 ph. This, in parallel with the 100
mmf capacitor will tune to 7200 kc. For construction details of the trap refer to the accot.npanying photographs. On each end a small hole
is drillecl through both the wood and thin wall
for the #14 copperweld wire. Both ends of the
trap are tinned for a good electrical connection.

GIANT ]IEW CATATOG
Anlenno Construcfion
Dimensions of the antenna are as follows: A
center insulator is fed on each side with the
center and braid, respectively,of a 50 ohm coax
cable. Exactly 31 feet 4 inches on each side of
the center of the insulator, install the traps with
the larger thin wall toward the center to prevent water from collectingaround the wooden
dowel. The outer sectionsof the antennaextentl
beyond each trap 22 teet for a total antennit
length of 108 feet. This is shown in fig. L
Theoretically the center of a dipole should
have an impedanceof 72 ohms. However, most
hams do not place their antennashigh enough
to be l/a wave length above ground, and as a
result the impedance is usually lower and 52
ohms gives a better match.
Feeding with RG-8/U coax the best feeder
length was found to vary with location but
around 70 feet seemedto give the lowest s.w.r.
on all bands.
As in all antennas, maximum efficiency is
available only at one frequency in each band,
and the s.w.r. will increaseas the transmitter is
tuned farther from the resonant point. It does
not changemuch for abotrt 100 kc on each side
of the resonantfrequency.
lf you are interestedin operationin the c.w.
portion of the bands the center sectionsshould
each be made two feet longer and the end sections should be made three feet longer for a total
length of 118 feet. The trap should also be
tuned to 105 mmf before winding the inductances.This will give a much lower s.w.r. in the
area of the bands you are most interestedin.
This antenna offers an interesting and inexpensive building project and will allow the
average ham with limited space and budget a
chance to improve his transmitting efficiency

County Identity Ctarified
While we feel USA-CA Rulesregardingcounty
identity are not subject to interpretation, thel.e
h a s a r i s e na q u e s t i o no f w h e t h e it h e n a m i n go f
just the collnty on QSLs for mobile operations
suffices.Obviously if the mobile station is within
a city, both city and county should be named if
for no other reason than common sense.However,for mobileor portableoperationsnot within
a city proper and when such QSLs bear the markings /M or /(district), and countyis named,then
county identity is complete for purposes of
USA-CA.
Regardlessof printed matter on any QSL card
or postmark, the statementby the operator that
the contactwas made from a statedcity, or city
and county,or county,is the valid QTH of contact for USA-CA purposes.USA-CA is concerned only with common sensevalid proof of
contactwith countiesand is not concernedwith
technicalities.

in fact "letters" and more than one could not be

Llnder this P.O. decision then, ARRL's eSL
Bureausalso were in violation of interpretation
of the postal regulations.The LeagueCeneral

to the Post Office Department with claim that
the informationloggedon QSL_cardswasin fact
only confirmation of over-the-aircontacts alreadymadeand recordedunderFCC regulations;
thereforewere not original lettersrequiring action on the part of the receiverbeyondthat alreadycontainedin tbe radio log.

You will note that this young man, very much

stalled a coax connector for the 6 meter band
antenna input. He tapped the coil I turn from
the bottom for a better match for a beam antenna. This modification allows the 50 mc antenna to remain connected,and still provides
a 2 merer converterconnection,Tbe oiiginal 6
meter coil connection to the antenna terminal
strip is, of course,removed.Thank you, KBZHZ.
Incidentally, to further improve the He-170,
replace the tube rectifier with silicons.This cuts
down the internal heat.

We have been receiving a number of letters
which go somewhat like this: ". . so because
you are in Europe, we would certainly appreciate your telling us all about living conditions,
jobs. travel.worthwhilethingsto buy, etc.,over
there."
Although we are happy to help fellow hams
with specific questions we cannot (nor do we
have the time) to write long essayson Europe.
Again, do not forget the two IRC's or 25c in
coin for a direct answer from us. We cannot
bear the postagebill alone.
Our bestto you this month.

Here on the eastcoast,two very strong foreign
commercial or governmentRTTY stationshave
appearedat 3608 and 3650 kc. First noticedin
November, these stationsare using 850 cycle
shift and continuous tape transmission;however, their transmissionspeed is apparently
greaterthan our FCC-decreed
60 w.p.m.,so most
of us cannot copy them. Our c.w. friends undoubtedly are cussin' us out for this. It is suggestedthat we passalong the word that theseare
/lol amateur RTTY stations; and. that amateur
RTTYers also must sign in Internal Morse code
as well as in the teleprinter code.

Atso it will hurt my antennalocationquite a bit.
I now have a 50 ft. pole right beside the ocean.
My wife. by the way. is W9VFP. I'm going to
tly and get her a call here, but don't know for
sure if it will bc possible.
"Six has provided many interesting hours for
me down here. I'm very anxious to see what it
has to offer next year. l'm well into my third six
nreter logbook since the first opening after I got
my ticket. back on November 25. 1962. l'll bc
looking forward to ntore of the same next season.
Still need those W7 states,Minnesota. KH6 and
KL7. I'll be trying this winter to stir up sonrc
nrore activity down this way. I would like to see
beacons on some of the islands if possible' It
would be interesting to find out more about
propagation such as you mentioned some months
ago via the north-south Path."
From Portsmouth. Va., comes word that
"went
over our head in the CQ Summer
K4NEH
V.H.F. Contest in August." Vernon had about
65 contacts in four states (Va., N.C., Minn. and
Tenn.), coming in with a grand total of 7289
points. Three new stations are now on in the

"Ask
VPTCX where those
K4NEH continues.
QSL cards are? Still waiting. Also waiting for
VE2BEW and VElAHR. Bob, let's get a gun on
those boys in South Carolina Haven't heard one

adopt a broacl policy of genuinely trying to upgrade the AnlateLrr Service.
In this connection. I would like to add a further point. The directors of the ARRL are elected
individLrally b-v the members in each of the
League's l6 divisions. They in turn elect a majority of the Executive Committee from among
their own members. This is a thoror:ghly democratic procedure.
Grass roots control of League affairs by the
m e m b e r s h i p i s d e m o n s t r a t e d b - vt h e f a c t t h a t h a l f
of the present Directors of the Board. as well as
all of the Director-nrembers of the Exectrtive
C o m m i t t e e , t h e C e n e r a l N I a n a g e r .t h e G e n e r a l
Counsel and the Presiclcnt have been newly
chosen within the last fir'e years.
ln the past )ear that I have been associated
with them. I have founcl the Directors to be witho u t e r c e p t i o n a s i n c e r c a n d c o n s c i e n t i o l l sg r o t l p
o f m e n . d e d i c a t e t lt o t h e b e s t i n t e r e s t so f A m a teur Radio. I anr proud to servewith them. and
I am in full accord with the policies thcy have
adopted to strengthen Amateur Radjo.
ln conclusion, it is my opinion there are two
general courses of action that are open to us.
The first is to drift along, do nothing, and hope
f o r t h e b e s t .T h i s i s t h e e a s y w a y . a n d t h e c h a n c e s
are that if we choose it we will get thoroughly
clobbered, one of these days, at home as well as
abroad.
The second alternative is to face up to the
f a c t s a n d s t a r t t o d o s o m e t h i n g c o n s t r t l c t i v et o
preserve Amateur Radio for the future. That is
the sole reason behind the Board's recent action.
and I think the Directors are to be congratulated
for their courage in taking the initiative.
Thank you.
