Introducing EICO's New "Cortina Series "!
Today's electro-technology makes possible near -perfect
stereo at moderate manufacturing cost: that's the design concept behind the new EICO "Cortina" all solid
state stereo components. All are 100% professional,
conveniently compact (31 /8 "H, 12 "W, 8 "0), in an
esthetically striking "low silhouette." Yes, you can pay
more for high quality stereo. But now there's no need
to. The refinements will be marginal and probably
inaudible. Each is $89.95 kit, $119.95 wired.
Model 3070 All- Silicon Solid -State 70 -Watt Stereo
-
-
Amplifier: Distortionless, natural sound with unre-
stricted bass and perfect transient response (no inter
stage or output transformers); complete input, filter
and control facilities; failure -proof rugged all- silicon
transistor circuitry.
Model 3200 Solid -State FM /MPX Automatic Stereo
Tuner. Driftless, noiseless performance; 2.44V for 30db
quieting; RF, IF, MX are pre-wired and pre -tuned on

related troubles. The last chapter in the book
explains in detail how to test and troubleshoot
with color -bar generators. Without this helpful

How to get into one of today's hottest
money -making
fields-servicing 2 -way radios!
More than 5 million two -way transmitters have skyrocketed the demand for service men and field, system, and R &D engineers. Topnotch
licensed experts can earn $12,000 a year or more. You can be your
own boss, build your own company. And you don't need a college
education to break in.
s
WOULD YOU LIKE
to Start col-
HoW
lecting your share of the big
money being made in electronics
today? To start earning $5 to $7 an
hour...$200 to $300 a week...$10,000
to $15,000 a year?
Your best bet today, especially if
you don't have a college education, is
probably in the field of two-way radio.
Two-way radio is booming. Today
there are more than five million twoway transmitters for police cars, fire
trucks, taxis, planes, etc. and Citizen's
Band uses -and the number is growing
at the rate of 80,000 new transmitters
per month.
This wildfire boom presents a solid
gold opportunity for trained two-way
radio service experts. Most of them
are earning $5,000 to $10,000 a year
more than the average radio-TV repair man.
Why You'll Earn Top Pay
One reason is that the U.S. doesn't
permit anyone to service two -way
radio systems unless he is licensed by
the Federal Communications Com-
mission. And there simply aren't
enough licensed electronics experts to
go around.
Another reason two-way radio men
earn so much more than radio -TV
service men is that they are needed
more often and more desperately. A
home radio or TV set needs repair
only occasionally, and there's no real
emergency when it does. But a twoway radio user must keep those transmitters operating at all times, and
must have them checked at regular
intervals by licensed personnel to
meet FCC requirements.
This means that the available licensed experts can "write their own
ticket" when it comes to earnings.
Some work by the hour and usually
charge at least $5.00 per hour, $7.50
on evenings and Sundays, plus travel
expenses. Others charge each customer a monthly retainer fee, such as
$20 a month for a base station and
$7.50 for each mobile station. A survey showed that one man can easily
maintain at least 15 base stations and
85 mobiles. This would add up to at
least $12,000 a year.
Be Your Own Boss
There are other advantages too. You
can become your own boss -work by
yourself or gradually build your own
fully staffed service company. Instead
FEBRUARY- MARCH, 1967
of being chained to a workbench, machine or desk, you'll move around,
see lots of action, rub shoulders with
important police and fire officials and
business executives who depend on
two-way radio for their daily operations. You may even be tapped for a
big job working for one of the twoway radio manufacturers in field service, factory quality control, or laboratory research and development.
time and getting your FCC Licensecan be easier than you think.
Cleveland Institute of Electronics
has been successfully teaching electronics by mail for over thirty years.
Right at home, in your spare time,
you learn electronics step by step.
Our AUTO- PROGRAMMEDTM lessons and coaching by expert instructors make everything clear and easy,
even for men who thought they were
"poor learners." You'll learn not only
the fundamentals that apply to all
electronics design and servicing, but
also the specific procedures for installing, troubleshooting, and maintaining two-way mobile equipment.
Get Your FCC License...
or Your Money Back!
How To Get Started
How do you break into the ranks of
the big -money earners in two -way
radio? This is probably the best way:
1. Without quitting your present job,
learn enough about electronics fundamentals to pass the Government FCC
Exam and get your Commercial FCC
License.
2. Then get a job in a two-way radio
service shop and "learn the ropes" of
the business.
3. As soon as you've earned a reputation as an expert, there are several
ways you can go. You can move out
and start signing up and servicing
your own customers. You might become a franchised service representative of a big manufacturer and then
start getting into two-way radio sales,
where one sales contract might net
you $5,000. Or you may be invited to
move up into a high- prestige salaried
job with one of the major manufacturers.
The first step -mastering the fundamentals of electronics in your spare
By the time you've finished your CIE
course, you'll be able to pass the FCC
License Exam with ease. Better than
nine out of ten CIE -trained men pass
the FCC Exam the first time they try,
even though two out of three non CIE men fail. This startling record of
achievement makes possible the CIE
Warranty: you'll pass the FCC Exam
upon completion of your course or
your tuition will be refunded in full.
Before Ed Dulaney studied with
CIE, he was a crop duster. Today he
owns the Dulaney Communications
Service, with seven people working
for him repairing and manufacturing
two-way equipment. Says Dulaney:
"I found the CIE training thorough
and the lessons easy to understand.
No question about it -the CIE course
was the best investment I ever made."

Cobra V CB Transceiver
Running a whopping 100% modulated 5 -watt
input on any five channels, the set puts up quite
a showy front with a walnut grain finish ('neath
that frilly walnut finish is an all steel housing).
For those wise guys out there in the reading
audience who come on strong with the fancy

A Real Charmer. No, the Cobra V isn't some
kind of late model snake, it's a glitzy new CB rig
which just blew on the scene from the windy city.
The Cobra is right in step with the latest trends
in CB gear -little in size, all transistorized, low
cost, efficient; and it claims to be the first rig on
the market with a "special protective circuit for
transmitter components."
In the performance department, the Cobra V
has transistorized transmit /receive switching
(that means no moving parts and therefore less
chance for mechanical failure when a tired old
relay drops dead of fatigue). There's also a clever
new voltage filter to improve the clarity of the
signals inhaled by the Cobra V.
B &K
what's
to
read
tech talk, we note that the Cobra V comes on
strong with better than half a microvolt sensitivity (for 10 db S/N) and a selectivity of 6 db
at ± 3 kc -O.K.?
You can get enough literature on the Cobra V
to stuff a megacycle if you drop a card or letter
to the manufacturer, B &K Division, Dynascan
Corp., 1801 West Belle Plaine Ave., Chicago,
Ill. 60613.
A' Matchless Antenna? We've
seen some wild looking things
connected to the output of CB
rigs but the Antenna Specialists
MACH III makes the rest of them
look like as tame as a tranquilized
bunny rabbit.
Not knowing exactly how to
describe it, the best we can do is
simply parrot the description of
the thing as stated by the
manufacturer: "A spiral shaped,
printed- circuit coil, waterproofed
and shock -suspended inside a
wing- shaped ornamental base."
This all boils down to the fact
that this circuitry is a "involute
transducer" (wha ?).
Now that the engineering is clear to you (because it certainly isn't to us) we can get into the
performance of the little devil. It's a 32 inch
steel whip, basically, set into a futuristic cyco -lac
plastic base containing all of the sophisticated
jazz we just told you about (don't ask us to repeat it please).
Available in a variety of mounting types (with
or without shock spring), the MACH III is DC
grounded for optimum SWR across the band.
The antenna may be peaked up to your particular rig by means of an adjustment in the base.
Prices (depending on mounting hardware)
range from $12 to $25. The folks who figured
this one out are at Antenna Specialists, 12435
Euclid Avenue, Cleveland, Ohio 44106.

One Of Our Aircraft Is Missing. Not long ago
we suggested that walkie-talkie users might make
good use of the Class C radio control channels
which lie between the Class D CB channels
thereby avoiding harmful interference from their
more powerful 5 -watt brothers. Unfortunately
we forgot to consider the possible effects on the
radio controlled aircraft using these channels. A
number of model fliers quickly brought this to
our attention- mentioning several instances
when a walkie- talkie became the instrument of
destruction to a prized model aircraft; knocked
it right out of the sky.
The aircraft folks will be moving to their new
70 MHz me channels and perhaps we might hold
off on invading their 27 MHz channels until
they're all moved out.

Lit -Up Base Antenna
The "Speakin' Beacon" Citizens
Band base station antenna is a
27 MHz omnidirectional coaxial
antenna with a permanent- circuit
neon light built into its tip. Whenever the transmitter is keyed, the
11
neon tube glows, visually verifying the RF power output and acting as a beacon to help guide mobiles. A Stati -Light ball surrounding the neon tube dissipates static
electricity and helps eliminate
noise. The ball, part of the neon light circuitry,
provides proper capacity to ground to generate
necessary voltage to light neon when RF energy
is present. The Speakin' Beacon is 19 feet, 3 inches,
aluminum, built to withstand winds up to 80 mph,
has its own built -in lightning protection, and can
be installed anywhere a vertical pipe would Lit.
Gamma matched, it has exceptionally low VSWR.

Ham
Station
in a
Needle
By DICK FLANAGAN
Many's the Ham longing for a super sky hook, but Bob Ryan, W7GWA, isn't one of
them. For Bob numbers among the operators of what may very well be the highest
Ham station in the world, which, because of
its unusual location, also boasts a skyhook to
top all skyhooks.
Installed on the observation deck of the
Seattle Space Needle some 550 feet above
the city's rooftops, station WA7GBD is operated by the Space Needle Amateur Radio
Club. And Bob, who is one of the club's 75
members, takes turns working Hams around
the world from this strange Ham- station -ina- needle.
Bob generally works 20 -meter SSB, using
Drake TR-4 transceiver and a companion
RV -4 remote VFO. Currently, the station is
heard as far away as Japan, Brazil, and Rusa
22
sian Siberia. Even greater range and reliability are expected when the present 300 watt transmitter is joined by a kilowatt
linear, which is now on order from Drake.
When it arrives, Seattle's Ham- station -in -aneedle will be as powerful as any amateur
station going.
In spite of the Club's extraordinary offerings, there are no membership dues or other
fees. The Space Needle organization simply
issues free elevator passes to all members so
they can have ready access to the station at
any time. And since nearly a million people
visit the observation deck annually, the public relations value of the station is thought to
be excellent. Most of the visitors see the
station in operation, frequently handling
traffic from U.S. servicemen on ships and at
bases overseas.

Detector for FM, AM, CW and SSB
High- Frequency Problem
How can 1 modify a communications receiver
to work on FM as well as AM, CW and SSB?
I have a (Brand X) 4 -tube superhet shortwave
receiver which has good selectivity and sensitivity up to about 14 mc. But, from there up to
30 mc, it lacks the ability to pull in all but the
very strongest signals. Would the addition of
a preselector solve this problem?
-C. L., Brantford, Ontario
Have you had the tubes checked on a critical
tube tester? Try new converter and IF-amplifier tubes. Also adjust the highest frequency
band RF trimmer when tuned in to a CB or
10 -meter ham station and again when receiving
the weakest signal you can tune in. If you have
or can borrow a signal generator, realign the
IF transformers. Be sure to use a proper outdoor antenna. A preamplifier (preselector)
would help, but it doesn't sound as if you were
getting all of the performance that was designed
into your receiver.
-R. H., Seattle, Wash.
You can replace the AM detector and first
AF stage with a gated -beam tube (such as
6BN6) using the circuit shown in the schematic
diagram. The existing IF transformer feeds the
control grid of the tube. When SI is set to
AM and S2 is set to F (for fast AVC response)
or S (slow AVC response), the grid and cathode
function as a grid leak or diode detector and
the rest of the tube functions as an AF amplifier.
AVC voltage is developed across R2 -R3 and is
tapped off at their junction. Diode DI prevents
AVC action until the signal reaches a satisfactory level. With S3 open, the positive bias on
the quadrature grid can be varied with R1 for
minimum audio distortion.
When SI is set to SSB /CW, the signal from
the receiver's BFO (beat frequency oscillator)
is fed to the quadrature grid to form a product
detector. AVC attack time can be selected by
setting S2 to F or S.
For FM narrow band reception, Si is set to
FM and C1 -LI are connected to the quadrature
grid to form a gated -beam discriminator. By
setting S2 to the None position, AVC is cut out
and the tube also functions as a limiter. Closing
S3 makes it possible to vary the cathode bias
on both the control and quadrature grids with
RI for maximum sound recovery and best
limiter action. The quadrature coil (LI) is
tuned to the same frequency as the receiver IF
and trimmed for maximum FM audio recovery.
Sure Mike!
Can you give me the address of a company
that produces a transceiver-type mike for ham
transmitter use?
-L. Dec., Austin, Texas
Roanwell Corp., 180 Varick Street, New
York, N. Y. 10014 makes mikes of this type.
So do many others including Electro- Voice,
Turner and Sonotone. Try your local electronics -parts distributors who should have them
in stock.

A Hot Note
recently read in Variety that a musician was
as a result of electrocution while playing
an electric guitar. How can this happen?
-H. H., Van Nuys, Calif.
He must have been in a bathtub or standing
on a wet floor when it happened. Alvino Rey
and others have been playing electric guitars for
years with no ill effects. The danger of electric
shock can be great under some conditions. For
example, a skindiver, who was testing an underwater TV camera in Al Ogilviés swimming pool
in California would have been electrocuted
when he took the camera into the pool if it
hadn't been noted that the camera was "hot" to
the touch when the camera was handled at pool side. Grounding the shield of the camera cable
saved the skin diver's life. The camera was "hot"
because of the line -filter capacitors in its power
supply which put the case about 60 volts above
ground potential. The same hazard exists with
TV sets and hi -fi devices. Moral: Don't touch
any appliance connected to the AC line when
bathing.

Does it Pay?
How can I boost the input power of my
5-watt, 2 -meter transceiver to 75 watts?
-L. B., Morton Grove, Ill.
Get a linear amplifier. Connect its input to
the output of your transceiver and the antenna
to the output of the linear amplifier which
should have internal antenna switching facilities.
However, you can quadruple your effective
radiated power by installing a 6 db gain antenna
which costs less than a linear amplifier and
won't increase your electric bill. Call AM 2 -2903
in Chicago and ask for Griff. He's near you and
can tell you what kind to use, where to get one
and for how much.
Just a Minute
In one of your articles about building a
novice antenna loader, a B & W Miniductor coil
form was specified. Where can I get one?
-D. P., Cuyahoga Falls, Ohio.
It is made by Barker & Williamson in Bristol,
Penna. If you can't find it at your local radio
parts store, write to Mr. A. Consalvi at B & W.
Carrier for Frequency Standard
How can I recover the unniodulated carrier
from an AM broadcast station so I can use it
as a frequency standard?
T. H., Pittsburgh, Pa.
Rig up an oscillator using a circuit such as
the one shown in the diagram. Place it near an
AM broadcast receiver and tune in a station at
the desired frequency. Then tune the oscillator
close to the broadcast -station frequency so you
will hear an audio beat (whistle). Carefully
tune the oscillator for zero beat, the point where
no whistle is heard. You'll have it set right if
you get a whistle when you turn the tuning
capacitor either way. When set to zero beat
with a signal of known frequency, your oscillator will be within a few cycles of that fre-
-J.
quency.
Four IN1693 or similar diodes, a 6.3 -volt
filament transformer and an electrolytic capacitor, connected as shown in the diagram, should
do the trick. The no -load voltage should be
around 9.8 volts which will drop somewhat
under load.
Engineering Takes Years
I want to assemble a transistor radio capable
of receiving radio signals in Canada from radio
stations of Indo -Pak Subcontinent, especially
the following: All India, Radio Delhi, Radio
Pakistan Karachi, Radio Lahore (Pakistan),
Radio Sirinagar (occupied Kashmir), Radio
Jammu (occupied Kashmir), Radio Jallunder
(Panjab, India), Radio Ceylon (commercial
station operated from Bombay, India), Radio
Dacca (Pakistan) plus local longwave stations.
If it is possible, could you please draw a
diagram and advise equipment to be used to
produce a "perfect model."
-A. A., Vancouver, British Columbia
If it were possible to give you a diagram of
an all-transistor, all -wave receiver meeting your
requirements, we would do so gladly. There is
such a receiver on the market (National) but it
costs more than $1,000. It probably cost the
manufacturer more than $100,000 and several
man -years to design it. While we could dream
up a diagram, there are countless other problems you would have to solve yourself. It would
cost you a great deal in money and time with
no assurance of satisfaction. As a compromise,
you might consider Lafayette's 11 -band portable
at around $160 or Zenith's Transoceanic, ready
to use.

Please don't make fun of the use of a mechanical filter with a "Q" multiplier. I have a
Hammarlund HQ -100 with a Lafayette mechanical filter and the results are excellent. Adjacent channel QRM is much reduced and
stability is considerably improved. For CW
reception it cannot be beat for the price.
-R. C., Manchester, N. H.
Of course a mechanical filter is a good device.
But, in a receiver which already has a crystal
filter, why add another one? Since your receiver
does not have a crystal filter, the addition of a
mechanical filter makes sense.

-A reader, Someplace, USA
The first diagram is the circuit of the oscillator stage of your set, according to the
schematic you sent. The second diagram is the
modified circuit. Use the same oscillator coil
tuned by a trimmer capacitor. Disconnect the
oscillator section of the main tuning capacitor.
You still use the tuning dial to tune the RF
amplifier and mixer to 39.46 MHz. For that
frequency, use a 28.76 MHz crystal.

OCR for ZIP
What is OCR and what is it used for?
K., Philadelphia, Penna.
-N.
One meaning of OCR is optical character
recognition, a technique for reading printing
and written matter electronically. In one system, each character is looked at quickly by a
flying -spot scanner, a kind of TV camera.
What the scanner "sees" is sent in the form
of electrical signals to logic circuits which
identify the character and send a digital signal to a computer. For example, the logic
circuitry can determine the difference between a handwritten lower-case E and a
lower-case L. Both look alike but one is
taller. OCR systems are used to read accounting forms and other documents as well
as the ZIP code on letters.

-W. A. W., Huntington, West Va.
Checking with a major TV station in New
York City, it was learned that no back -up film is
used. In case of failure, the operator probably
winds the film back up on the reel and reruns
it. Thus, you will see it from the beginning.
Even though film problems do sometimes arise,
station and network executives often let operators know that "it will not happen here."

You can use the circuit shown. The transformer furnishes 3.15 and 6.3 volts AC. Plate
voltage is obtained from the AC line through a
voltage divider composed of four No. 327 pilot

-P. L. McG., Knoxville, Tenn.
Looking up the circuit of your sets we find
that a noise limiter is included and the sets
should be very sensitive, the latter accounting
for the noise. You probably live near a busy
street and pick up ignition noise from passing
cars. Try moving your base antenna away from
the street and, in your car, suppress the noise at
the source with adequate suppression devices.

By KC. Kirkbride
It all started with a pill, a pill that was a radio station, a radio
station that could transmit "news" direct from a human stomach.
The pill was followed by a camera, a camera so small it could be
swallowed and photograph a man's stomach in living color.
At first, no one took these tiny pioneers very seriously. For at the
time medicine appeared to be in one corner, electronics in another,
and the two weren't going to pull off any full- fledged marriage for
ever. But that was before man began to seriously

Tuning in
on the
bodys ills
This realization led to a new science called
biomedical engineering, a discipline that
combines electronic with medical techniques,
sometimes borrowing from space and military research to create new diagnostic wonders. One day soon such marvels may rule
out the hit -or-miss human error that has
characterized medicine up to our time. Come
that happy hour and current medical techniques may seem as medieval as when man
applied leeches to cure his aches and pains.
All One. Now being introduced in major
hospitals is a master six -unit electronic medical internist built by Honeywell. Its big claim
to fame is the fact that it can instantaneously
record eight types of information about a
patient and show them on a 17 -in. screen.
ECG, EEG, EMG, PCG, and other electrodes sensing surface and below -skin
changes show heart, brain action, and skin
temperatures on a television screen to a doctor as he operates. This new system's sharp focus screen is so bright it can be seen 20
feet away. And the device promises to elimi-
nate much of the hazard in surgery as well
as store vital information for later consultation and record.
Life Savers. Not as comprehensive but
already a veteran of 250 neurological operations is an IBM -Mayo Clinic system on duty
at St. Mary's Hospital in Rochester, Minnesota.
To monitor patients, electrical detector
signals are converted to digital coding, processed and printed out on a special typewriter to be scanned by a closed -circuit TV
camera. The machine will show a patient's
heart and breathing rates, arterial pressures,
and body temperatures on a 14-in. screen
while an operation is in progress. Meanwhile, a 5 -in. satellite oscillograph set up
near the patient will give automatic electrocardiograph readings.
Warnings. Another team of Advanced
Systems engineers borrow techniques used to
analyze missile status before test firing. Their
purpose: to have "early warning" of changes
in a patient's condition before clinical signs
appear.
Sensors relay information to an IBM 1800
computer, report on an operating room
screen warning of changes that could bring
on an emergency in the seriously ill.
Nuclear.
Still another biomedical life-

Some advances in medical electronics fall in the evolutionary
(rather than revolutionary) category, with recent improvements
in X -ray equipment a prime
example. X -ray installation at
right dates from the late '20s
and consists of a vertical fluoroscope in conjunction with a radiographic table, with the same
power source being used for each.
Note that over -table tube is
still of the non- shockproof type,
with exposed high -tension leads.
Modern X -ray installation (at
left) conceals X -ray tube in
rayproof body of enclosed table,
while image is now made thousands of times brighter by means
of image intensifier on deck
extending across table. Further,
over -table X -ray tube is supported
on telescoping column, in turn
suspended from overhead
carriage traveling on ceiling
racks. Resulting arrangement
permits rapid positioning and
angulation of X -ray tube.
saver supplying emergency information is
nuclear. A surgeon may need to know before an operation if a patient needs a transfusion, what kind of anesthetic may be best,
and whether or not the heart is getting
enough blood.
To answer these questions, Picker X -Ray
built a machine it calls a "Hemolitre." This
unit shows just how much blood is circulating in a patient, information that can mean
the difference between life and death in heart
cases, serious surgery, or an automobile accident emergency.
Picker does it by tagging a small amount
of serum with a radioactive substance such
as Iodine 131 which is then injected into a
patient's bloodstream. A few minutes later,
a small sample of blood is withdrawn. The
Hemolitre then calculates the radioactive potency of the blood before and after the injection, as well as the radioactivity of the
serum itself.
This information is then fed into a computer which spins its electronic gears and
ultimately reveals what the doctors want to
know on its front panel.
FEBRUARY- MARCH, 1967
Chair Is Examiner. Philco isn't that formal. Their engineers at Western Development Laboratories division at Palo Alto,
California, have developed a diagnostic
chair. Once a patient is comfortably seated,
the chair picks up respiration rate, pulse rate,
-
heart sounds, and electrocardiograph readings, then records the data on graph paper
all without the patient's knowledge!
While the Philco sensor chair borrows its
tricks from space research, a new development at RCA was once in the Army. The
image amplifier, adding amplification and
TV skills to the already powerful electron
microscope, is a direct descendant of the
World War II "Snooperscope." Combined
with an image orthicon, it gives 50,000
times the light gain of the conventional studio camera.
The very intense intensifier can now see
and record images too faint to be seen by an
electron microscope alone, and it will even
record them for TV tape or film playback.
Honorary RCA Vice President Dr. Alfred
N. Goldsmith calls the new amplifier "among
the most powerful and useful electronic de39

Dr. Goldsmith is so enthusiastic about the
amplifier he hopes we will one day improve
electron-optical powers to the point where
sequences of nucleic acids will be seen,
classified, and their significance N isually decoded.
Living Color. Probing even more deeply
into human body secrets is the Picker MagnaScanner, a new machine that will scan inner
organs and glands in both black- and -white
and color. Mounted on the end of a beam
on a scanner that can be rolled across the
room and wheeled right up to a patient's bedside, the machine scans radioactive material
inside the body.
A photorecorder picks up a black -andwhite picture of the organ or gland involved
at the same time a multicolor dot recorder
pictures the same areas in eight colors. The
two systems, black -and -white and color, are
designed to supplement each other, showing
different versions of the same organ to the
diagnosing doctor.
Already in use at Cedars of Lebanon Hospital in Los Angeles, the scanner pictures
a patient's liver, spleen, pancreas, parathyroid, brain, heart, lungs, thyroid, kic;neys or
spine.
Sound Tells. Sound waves can diagnose,
too. Doctors at the Albert Einstein Medical Center in Philadelphia say a good many
elderly patients cannot take prolonged X -ray
examination, so a medical -engineering team
40
built
a machine that scans people with sound
waves. High- frequency sound cites vascular
disease, particularly hardening of the arteries,
by photographing an artery blocked by deposits or harmed by an aneurysm.
Ultrasonic waves at a frequency of about 2
MHz reflect from body tissues, register an
image on an oscilloscope, and are then pho-
tographed for future records.
Skin Changes. Even a more revolutionary diagnostic tool is one that spots disease
by skin -temperature changes.
Called thermography, the technique hinges

on the theory that the average internal temperature of the body remains pretty much
unchanged if a person is healthy. Skin temperature, in contrast, fluctuates, depending
on both internal and external factors.
At the Einstein Medical Center, physicians
scan skin surfaces with infrared radiometers
to cite internal disturbances. The method
calls for rapid, high -resolution infrared
scanners and very basic scientific know -how
to be able to accurately analyze. But in
spite of the revolutionary aspects of the new
technique, it has already won its colors by
early detection of some types of cancer and
vascular troubles.
Model Organs. For the new electronic
internists to completely rule out diagnostic
error, the modern doctor applying the techniques must know more about the workings
of the human body, still enigmatic in many
respects. This information IBM and University of Mississippi School of Medicine engineers and physicians try to supply. Borrowing from space science they successfully simulate body organs with a computer.
FrtBauABY-MARCH, 1967
Feeding all known information along with
mathematical descriptions of body organs
and systems into analog and digital computers, they simulate such organs as the human lung, kidney, and heart.
One model of a kidney has already afforded doctors a clearer comprehension of
the relationship between kidney function and
high blood pressure. And they hope to learn
more about arterial blood pressure, blood
flow, and blood composition through a
mathematical model of the circulatory system.
For years, doctors have tried to discover
how kidneys control rates at which substances are eliminated or reabsorbed into the
body. To date, they have only theories, but
they now hope to solve their problem by
building a mathematical model. The computer can then show which theory best simulates actual function.
The Body A System. Dr. Arthur C. Buy ton of the Mississippi School explains the
work by saying he believes the body the best
engineered and most complicated system
known. Since it is controlled by several
hundred patterns, only a computer, he thinks,
can aid in understanding its workings.
To discover why elderly women fall and
break a hip more often than men, Moss Rehabilitation Hospital in Philadelphia has carried out another study. Two hundred women
clad in shorts and wired to an electronic
machine, walk across a "copper" carpet. Six
muscular movements are recorded: the angle
of each hip, knee, and ankle joint, plus muscular potentials during five walking positions.
Each of the motions is then measured
electronically with the thought that if the
doctors can find why the women fall they
may discover a preventive.
Pain Cure. For the study, analysis, and
diagnosis of the human body and its complaints, the new biomedical engineering has
already proved revolutionary in its promise
to rule out human error. But so far it has
come up with few cures.
One, however, seems so extraordinary it

Mounted on the wall at some level or other,
the then new -fangled creations could be utilized only with a preposterous amount of
stretching or stooping -and only if the party
line wasn't engaged.
Today, most of these phones have gone
the way of the Stanley Steamer, though a
few still lurk in attics and antique shops
(the one in the photos was picked up at a
country sale for a five -dollar bill). And
though their days as telephones are over,
such oldies can be returned to service in a
way grandpop would never have dreamed of
a conversation -inspiring cabinet for a
table radio.
Strip Treatment. The old oak wall telephone in the photos took its first steps toward its new role when it was dusted, then
given the strip treatment. All of the old
wiring and small parts were removed from
the inside of the main case, leaving only the
box and the exterior paraphernalia.
The front -hinged lid of the telephone
came off when we removed the screws from

one side of the three brass hinges. We then
cleaned up the main cabinet and the wooden
back, removing a variety of grease, pencil
marks, and stains. What we didn't touch,
of course, were the dents and scratches (remember, we wanted this to be an antique!).
Almost any long and narrow radio chassis
could have gone into the telephone cabinet.
The type or age of the radio really made
precious little difference as long as the radio
worked and would fit in the main compartment. Though we were tempted at one
point to use a small, battery- powered transistor job, we eventually settled on a new
G -E T1220A AM /FM table model (which,
incidentally, uses an AC /DC circuit).
Trial Run. Once the etched circuit board
had been removed from the radio's plastic
case, we temporarily lined up the chassis
and marked the mounting holes for its controls. Since we wanted to mount the dial
plate separately, we cut it free from the cabinet with a hacksaw blade. Having smoothed
off the rough edges, we laid the dial on the
side of the telephone case, carefully traced
around it, then slid the radio chassis into

be plenty of room to mount the chassis in the
telephone compartment and also to fasten it
to the dial.
Masking tape was placed on the marked
edge of the antique cabinet to serve as a
guide line for the dial cutout and to protect
the case against possible mars and scratches.
We then drilled two 1/2-in. holes on opposite ends of the masked area to start a small
saber saw. Since the oak case was very
hard, we were careful not to feed the power

Plastic Grille. We mounted a 4 -in. speaker at the bottom of the telephone case, having first drilled several 4/8 -in. holes and then
covered them with a small piece of plastic
screening. The line cord was passed through
another 3/s -in. hole at the speaker end of
the cabinet, and a knot was tied in the cord
at a point just inside the cabinet to secure
it against accidental stress.
Next, we replaced the circuit board in the

removed the chassis and drilled two '/o -in.

we drilled two mounting holes at either end
so the dial could be fastened to the telephone cabinet. The dial was mounted in
place and the radio chassis was then bolted

Finishing Touches. With the project almost completed, we then soldered the wires
from the output transformer to the speaker
voice-coil terminals and taped the FM antenna wire to the inside of the telephone
cabinet. After the radio had been mounted
and tested, we sealed the dial in place by
squirting rubber seal around the dial.
Later, we removed the telephone bells,

Dim View On A Dark Subject
You won't have to grope around blindly in your darkroom
after you install this miniature safe -lighting system.
by Robert Hertzberg, W2DJJ
fumble around in your photo darkroom trying to read the markings on an
enlarger lens or a print timer? The time you
spend in your darkroom will be much pleasanter if you install a very simple lighting
system using a few inexpensive parts, most
of which can be salvaged from an experimenter's "junk box." Even if bought new
they cost little.
The actual sources of illumination are a
couple of pilot -light assemblies with red jewels and No. 47 miniature bayonet -base lamps.
Why
44
These fit neatly inside 35 -mm film cans. The
holes for them are made in the can with an
ordinary penknife, the metal being very soft
aluminum. One can is mounted on the pivoted safe -light arm of the enlarger by a short
piece of brass or aluminum, which is bent
to throw the light upward to the rim of the
lens. The usefulness of the filter is not impaired at all: the whole assembly swings
back and forth smoothly. The other can is
mounted over the face of the print timer,
pointing downward.

The lamps are powered by a 6.3 -volt filament transformer which is enclosed in a small
wooden box at one end of a board used for a
base -the front portion of the base supports
the timer itself. The various dimensions of
the box are adjusted to suit the size of the
timer. The top of the box holds a line switch
and four binding posts; the right side, a
single AC outlet -for the timer's AC plug.
The light for the timer dial connects to
one pair of binding posts, the enlarger -lens

just as well, since the lamps are in parallel,
but the extra pair is handy if still another
light is wanted, perhaps to illuminate a clock
face or a paper safe. There is absolutely
no shock danger from the low- voltage wiring powered by the filament transformer.
Placed next to the enlarger, the timer transformer unit is very convenient to operate. The bright red jewels end all squinting,
yet do not fog the fastest black-and -white

The shocking truth about the bitter battles that may determine
the future of every Ham and CB operator in the United States
"It's wart" The words of a militant professional protest leader? Hardly. Fact is, they
were grumbled only recently by a fellow
radio operator
normally quiet and bookwormish chap who probably thinks twice
before he swats a fly. But this time he had
good reason to be infuriated. And his sentiments are typical of those being muttered in
radio circles throughout the country.
Several factors precipitated his declaration: first, the seemingly hostile attitude towards Hams and CBers by the Federal
Communications Commission; second, the
strained relations between the American Radio Relay League and Hams; third, the growing realization among operators that they
might well have to fight to defend their operating rights and privileges!
The battle lines are most definitely drawn;
wits are being sharpened right this minute!
But what are the issues? What is at stake,
and what brought on this unusual battle royal? Many of the facts have never been revealed -until now, that is.
Down The River. It is believed by some
that the Hani radio situation began at a
-a
46
private meeting in New York between the
FCC and the executives of the ARRL and
QST (the ARRL's official publication). With
a major international radio frequency allocation conference looming on the horizon,
the FCC regretfully reported that some of
the new African nations were complaining
about the lack of radio frequencies for their
use; possibly they would try to steal the Ham
frequencies. If such a thing actually came to
pass, Hams throughout the world would
blame the FCC because it permits U.S. citizens to get Ham licenses with a minimum of
red tape, exams, and waiting time. As a result the U.S. has amassed a tremendous number of Hams per capita -many of them
rotten operators who have earned (for
American Hams in general) an international reputation as obnoxious loudmouths running far more power than is necessary.
The FCC was on a spot and felt that
something would have to be done to show
the rest of the world that U.S. Hams weren't
so bad as to cause the loss of Ham radio
frequencies. The ARRL was quick to accept
the challenge of coming up with some sort of
RADIO -TV EXPERIMENTER
solution to save face for the Commission.
The ARRL brass itself had long been unhappy with many of the new breed of Hams
as
and said it had "increasing concern
to whether the basic purposes and objectives
of the amateur radio service, particularly
those relating to technical qualifications and
proficiency," were being achieved. The
League claimed that many Hams "just go out
and buy their equipment, plug it into the
light socket, connect an antenna and operate."
All of this was far below the dignity of the
pompous and tradition- steeped League executives, many of whom still live in the days
when operators wound their coils on oatmeal
boxes and put India ink on crystals to change
frequency. It seemed to them that this would
be the right time to weed out these new rascals by either kicking them off the air altogether or at least openly branding them as
second-class operators.
The Plan. Back the ARRL folks went to
Connecticut and into the conference room
for secret talks. The result of the brain picking session was a mish-mash of ideas
which had been previously rejected by the
ARRL and the FCC, only now the plan was
rearranged and dubbed with the new title of
"Incentive Licensing." Worded in fancy legal terms, it was rushed down to the FCC
on a silver platter for prompt approval. QST,
having the uneasy feeling that the plan might
not sit too well with some ARRL members,
gingerly tried to explain Incentive Licensing
to its 105,000 reader /members. The result
was an upbeat explanation intended to sell
...
FEBRUARY -MARCH, 1967
an idea which had few selling points (no
mention was made of the FCC's inspirational
role in its creation).
Stripped of the fancy frills, the plan suggests creation of a new "elite" class of Ham
license to be called the "Amateur First Class
License." This license would be available
only to those Hams who had held an Advanced, General, or Conditional Class License for at least one year.
To get the new license, the Ham would
have to take a new written exam which
would be harder than his previously taken
test: he would also have to pass a 16 -wpm
code test (existing General Class tests call
for 13 wpm) . Only operators of this new
license class (or those who held the coveted
"Extra Class" license, which is harder to
obtain) would be allowed to operate a phone
station on the prime DX frequencies below
50 MHz (160 through 10 meters). Those
Hams who couldn't pass the exam would be
forced to jam into a small band of phone
frequencies or use CW (which, for all practical purposes, is now obsolete).
In addition, all phone privileges, for Novice operators (the 2-meter band) would be
withdrawn. To round the plan off, the FCC
was asked by the ARRL to devise "distinctive" call -signs for each particular class of
license so that Hams would immediately be
able to ascertain the prowess of fellow ama-
teur operators.
The Prospects. The FCC's acceptance of
these ideas would see thousands of long -time
DX phone operators unceremoniously evicted
from their operating haunts until (and un47
It's Warr
less) they could pass a rougher exam than
they had ever before taken. (Fact of the
matter is that many Hams couldn't pass the
very exam they took to get their original
license if a year or so had elapsed.) Their
only hope would be to cram for the new
exam and, failing that, squeeze onto the few
remaining frequencies or pack their DX gear
in mothballs and migrate to the local-coverage VHF bands-where the FCC was to
reserve them some "exclusive" frequencies.
The regular VHF operator, already
plagued with split-up bands and class distinction between General, Technician and Novice class operators, would then be faced with
the prospect of slicing up the pie for yet
another group. For new immigrants from
the lower bands would be now joining the
VHF fraternity by taking away the regular
VHF operators' best frequencies. The idea,
of course, was to force the Technician class
VHF operator to get the incentive to step up
his code speed and pass a General Class license which would permit him to again
operate on his old frequencies.
Not On Your Life. The grass roots reaction was instantaneous and rather violent.
Enraged Hams flooded both the ARRL and
FCC offices with highly impassioned messages, all carrying the same theme, namely,
that they weren't buying even one little bit
of this proposal. CQ magazine, an independent Ham publication, offered its own plan
for upgrading the American Ham, but the
damage had already been done. The ARRL
plan had been formally submitted to the
FCC. And Wayne Green, Ham radio's angry young man (and publisher of another
Ham publication, 73, promptly sailed into
the ARRL with one of his famous tirades
over that one.
With cannon bombarding it from all sides,
the ARRL found itself in a rather embarrassing situation, especially since the FCC unexpectedly decided to play it cool and not
rubber-stamp Incentive Licensing into the
law of the land. The League was simply
left to hang by its thumbs while the folks
in Washington pigeon -holed the idea and
announced that they were "thinking over"
the plan's alleged merits.
The League landed out in the cold with
many Hams, too. In fact, when mid -1965
48
membership stood at 105,000, the League
had confidently predicted that mid-1966 rolls
would fatten up to about 108,000 to 110,000
members. In actuality, membership had
shriveled to less than 80,000 by mid -1966!
Panic Button. Not only had Hams
stopped renewing their memberships in the
League, but the proposal had triggered one
of the most horrendous business slumps Ham
radio had ever known. The proposal was
also the best explanation for one of the
most severe drops in license applications for
years.
The ARRL hastily engaged a public relations firm to find out what had gone wrong
and what had happened to its membership.
The poll- takers in turn announced that the
"crux of the situation" was that "if the people are indeed representative, then too many
Hams just do not feel the sense of personal
relationship with the League they want to
feel." In other words, most Hams just
couldn't understand why their good Ham
buddies at the League would have officially
proposed Incentive Licensing without having
taken the minor courtesy of asking members
for their opinion beforehand.
Meanwhile, the League itself explained
causes of non -renewal thisaway: that the
League was "out -of- touch" with the operators' interests; the operator simply "had not
gotten around to renewing;" and the operator
was "just not active" any longer.
By the fall of 1966, things had gotten so
desperate at the League that QST announced
what appeared to many to be an almost
pathetic last-gap measure to recapture the
badly fumbled ball; a panacea for regaining
its composure, lost prestige, and members.
The new idea, "Ham Quest 67," had the
League pleading (in QST), "Strength
through unity- that's what is needed."
Carefully skirting any mention of the
dreaded Incentive Licensing plan, the ARRL
rehashed all of the reasons why it's really
pretty wonderful to have the kindly ARRL
folks lending their prestige to Ham radio
and watching out for the interests of the
operators. Part of "Ham Quest 67" included sending out "ammunition to be used
in convincing non-members that they ought
to join the League . ," offering prizes
for the member or affiliated local club bringing in the largest number of new members.
The FCC? Yes, it's still thinking over
the proposal. But it also offers no inkling
as to when (if ever) a decision will issue
forth.

RADIO -TV EXPERIMENTER
w
The way things stand now, Ham radio has
been shaken to its foundations. Operators
are angry and confused. The industry is
pulling in its belt a few notches. And the
FCC (still meditating the Incentive Licensing
plan and seemingly unaware that Ham radio
has been hurt badly) has managed to find
the time to turn its helping hand towards yet
another radio service.
The CB Scene. In September of 1966, the
FCC sent a letter to all CB manufacturers
expressing the FCC's unhappiness with the
CB service. The letter innocently hoped
that the manufacturers (who have a $50million per year thing going in CB) "will
assuredly agree . . . that . . . a healthy
state of affairs" hardly exists. Manufacturers
were told that unless things got better the
FCC might consider putting a temporary
freeze on new CB licenses.
Established with the best of irttentions and
the worst of planning, the CB service was
created by the FCC on a frequency band
long regarded as useless for communications
because of the fantastic noises generated
there by industrial, scientific, and medical
electronic gadgets. Even Hams, some of
whom can turn almost anything into a useful
communications tool, had precious little use
for it. The band was "given" to CBers much
as a useless scrap of meat is tossed to a
dog, except that the FCC made it clear that
the meat could he eaten only in certain
ways, and only without enjoyment. The
Commission announced that CB communications could not consist of "hobby type
communications" or "idle chit chat."
Biting The Hand. As had been feared,
the CB operator picked up on the CB service
as a great way to be a "sort of" ham operator, using CB sets as telephones in a gigantic
party -line gossip and bull- throwing festival.
This sent the FCC into apoplectic convulsions and brought forth upon the users a
number of purges which saw new rules
FEBRUARY- MARCH, 1967
added, old ones strengthened, fines invoked,
licenses revoked, and even the old ogre of
the Federal Trade Commission trotted out
to frighten manufacturers. Despite these
efforts some 20,000 new license applications
still arrive at the FCC each month, and the
present license records show about 800,000
citizens licensed and using about 2' í- million
transceivers ( most of them incorrectly, one
can presume).
But what gives? Wasn't the FCC created
to control radio communications in the
task that includes issuing
United States
licenses and making and enforcing laws in
the public "interest, convenience and necessity"? True. But to enforce those laws it
receives a grubby little pittance with which
it must also run a huge monitoring network
to tune in on hams, CBers, commercial
broadcasters, business -band operators, police, ships, aircraft, and dozens of other radio
stations.
Although the FCC doesn't admit it openly,
some officials have privately confessed that
the money available for enforcement purposes simply isn't enough to adequately foot
its monitoring network. Nor is it sufficient for
the Commission to even attempt to enforce
most of the rules which it grinds out in
an almost endless procession. And therein
lies the rub.
CB is not only a newcomer to the family
of radio services, it's a difficult one to handle
at best. Worse yet, it's considered to be nonessential (for the protection of life or property or for informing the public, that is). The
FCC perhaps feels that if it can't get more
money, maybe it would be better off with
less radio services -and guess which is at the
uppermost tip of the totem?
It's a pity that the FCC can't keep some
of the money it takes in on fines and licenses.
CBers alone toss Uncle Sam about $160,000
per month in license fees. The money comes
into the FCC alright. but it goes right out
for placement in the government's kitty
where it is doled out in support of European
junkets for VIP's, insect research, and programs to lull farmers into not growing
wheat. Maybe a little of this money pumped
into anemic FCC veins would give it stomach
enough to carry on in the traditions of the
Great Society.
The most ludicrous thing about the whole
CB "dilemma" has yet to be mentioned.
For in spite of all the FCC's bellyaching,
nobody would be any the worse if CBers
were simply left alone to talk themselves blue
-a
49
It's Warr
wouldn't this be in the public "interest, convenience and necessity "?
Holding The Bag. Yet the FCC, staffed
by political appointees and public servants,
insists that it is acting in the best interests
of the American public. And despite the
abject poverty under which the FCC must
exist, when the COMSAT communications
satellite arrived on the scene an Act of Congress was rushed through to establish a new
FCC division just to handle the single satellite. (They probably haven't been too busy
in the new division since the rates are so
high that even the TV networks don't use it
very often.)
In the meantime, the American public has
watched the FCC give token interest to the
rigged quiz shows which duped 190-million
citizens (threats to put a freeze on broadcast
station licenses were not heard). Users of
essential communications services are crowding each other off the air due to lack of
sufficient channels, yet the FCC insists on
reserving 470 MHz worth of UHF -TV space
for a mere 250 broadcasters. And on the
marine bands, casual listening discloses opulent yachtsmen broadcasting language so
salty it would bring a blush to the face of
even the crustiest old navy Chief.
Are these problems of a lesser nature than
those facing CB or Ham radio? Are the
broadcasters truly the "darlings" of the FCC
(as has been suggested for years) ? Or is it
that the FCC is so understaffed that they
just haven't seen these problems or so underfinanced that they can't afford to do anything about them?
Regardless of the answer, one gets the impression that the FCC might perhaps have
had a master plan right along which would
explain some of its activities. A hint of this
was perhaps dropped when FCC Commissioner Kenneth A. Cox recently stated that
if all other alternatives fail to sufficiently relieve the present congestion, additional frequencies would have to be given to needy
services. This, he said, would be accomplished by a complete reorganization of the
radio spectrum (Cox likened it to "unscrambling an egg "). Obviously, new frequencies
can't be created by a wave of the FCC's
magic wand. They would necessarily have to
be taken away from "non- essential" radio
service.
It's Wad Yes, it really is a war, still a
cold one at this point but warming up by
the minute! Hams are thoroughly disgusted
at being made fools of by the ARRL, and
even more annoyed with the FCC which (for
reasons unknown to the operators) is still
fumbling with the Incentive Licensing
scheme. The ARRL is wobbling around on a
shaky pair of legs. Ham and CB manufacturers are wondering where they go from
here, and CB operators are still trying to figure out the justice in their paying $8 for a
CB license only to be divested of their rights
to freedom of speech and the pursuit of
happiness.
One guess is as good as another as to
where the next battle will be fought. If the
FCC would ever attempt to shut down these
services, it would undoubtedly be faced with
the specter of three million bootleg operators
jamming the reallocated frequencies. And
could the rumor be true that three million
CBers and Hams intend marching on Washington, right up to the FCC's Ham /CB office
(above a supermarket, by the way) to sing
"We Shall Over-modulate! "?

Privacy is almost a thing of the
past. Nearly every day the papers
detail some new horizons in eavesdropping, from the phone company
listening in to subscriber's conversations to executives bugging the rank and-file employee's washroom. And of
course, in this modern era of recording
tape and the scissors, even the most innocuous of conversations can be rearranged into the most damning of evidence. What to do? Nothing. You can
scream and the most you'll get is a few
sympathetic words from your Congressman, but not much else; for the
poletzi you complain to are up to their
ears in wiretaps and bugs, the Feds
have a sorry record of eavesdropping
prosecutions, the phone company
has been getting away with it for at
least 30 years, and your Congressman's indignation dies with yesterday's headlines.
About the only thing you can do is
fight to protect the truth; make certain
that what's used against you isn't the
result of some brilliant tape editing.
Make certain that when you tell your
neighbor "I need some money for termite poison" it doesn't come out "I
poison for money."
And you can easily protect yourself with the Tie -Spy-known in the
trade as an 007 FM mike. Just clip

where it can be transferred to tape in an
unedited version of what was said.
As shown in the photographs, the Tie -Spy
consists of an miniature, very- short -range
FM transmitter and a microphone that appears to be a high -class diamond -studded
tie-pin. You simply clip the mike to your
tie (naturally you're out of luck if you wear
bow ties), place a battery in the transmitter,
and you're on the air. A nearby confederate
can monitor your conversation on an FM
portable and handle the recording.
Construction. The unit shown is housed
in a plastic case approximately 21/s x 11/4 x
13/4 inches. Actually it can be made smaller
by using subminiature components. But to
keep the price down to rock bottom, we
have used standard components available
from Allied and Lafayette Radio (among
others). If you want to squeeze it into an

aient miniature values- nothing is really critical except the coil.
In a similar vein, the sound quality is
exceptionally "tinny " -readable but "tinny."
This is due to the low- impedance loading of
the high -impedance crystal tie-clip mike we
used to keep costs down. If you want to go
for a few extra bucks get a better mike, a
low impedance job -say a dynamic type
from 500 to 500 ohms. You can even try a
small transistor radio speaker, or might even
add a matching transformer. As we said,
nothing is really critical.
The electronics is assembled on a 15/s x
no inch section of perf- board. If you slightly round -off the corners the perf -board will
just fit into the plastic case.

Flea clips or Vector T28 push-in terminals

mount the C5 -L1 assembly, push in a set of

install a very short support lead from C5's

To insure frequency stability C6 should
be the silver mica type or its equivalent.
Space gets a little tight on top of the board
so miniature resistors (Mo or 1/s watt) and
capacitors are suggested. The components
on the bottom of the board can be "standard"

By Art Trauffer
Build this novel amplifier -in-miniature
and you'll no longer have to fire up a high powered stereo amplifier just to drive a pair
of headphones. This little stereo -headphone
driver will cost under $3.00, entail less
than an hour's work, and yet give you beautiful, clean, wide -range headphone reproduction. Utilizing the Euphonics Miniconic
semiconductor stereo phono cartridge, the

this simple setup is perfect for personal hi -fi.
The photo below gives some idea of how
easy this little amplifier is to put together,
and the schematic diagram reveals how few
parts are involved. No volume controls are
used because headphone volume is just right
for persons with normal hearing, and the
stereo balance is good.

Flat amplifiers are great

EQUALIZING
PREAMP
by Jay Copeland
One of the problems with home -made
phono amplifiers is that they are invariably
flat-good circuit design can make even the
cheapest transistor audio amplifier flat to
within ±3 db throughout the usable portion
of its frequency curve. You would think this
feature would be desirable, but its not
necessarily so when you take a hard look
at the signal supplied by the phono pickup.
The unequalized output voltage curve for
a typical ceramic cartridge extends from 50
to 10,000 cps. peaks at about 300 cps, and
falls about 6 db per octave at 50 cps and
15 db per octave at 10,000 cps. Also, the
impedance of a ceramic pickup decreases
as the frequency is increased. On top of
this non -linear characteristic the signal is

further complicated by the record manufacturers. Recordings are deliberately made
with reduced amplitudes at low frequencies,
a relatively flat middle frequency range, and
increased amplitudes at high frequencies due
to manufacturing difficulties in the preparation of plastic platters. Therefore, a carefully designed preamplifier circuit is needed
to boost the low- frequency signals, reduce
the highs and match the ceramic pickup's
impedance before passing an equalized audio
signal to the frequency -flat amplifier.
Fortunately, the recording industry had
decided on a recording equalization standard
(R.I.A.A.) and the characteristics of ceramic pickups are almost universally identical
with respect to frequency response and im-

pedance output. Now, a preamplifier can
be designed to straighten the frequency -output curve from a ceramic pickup's signal
prior to being fed to a flat amplifier.
How it works. The schematic diagram
for the ceramic- pickup preamplifier appears
to be a basic common-emitter type using an
npn small -signal transistor -except for the
collector-base network (resistor R2 and capacitors Cl and C2). Resistors R1 and R3
provide fixed base bias. The amplifier's input
impedance is made smaller than the pickup's
impedance and Ql's current gain is made to
vary inversely to the velocity response of
the R.I.A.A. recording characteristics.
The negative feedback characteristics of
the collector-base network does the equalizing-C1 is the effective circuit element for
frequencies between 30 and 500 Hz (cps);
R2 between 500 and 2000 Hz; and C2 above
2000 Hz.
The large amount of negative feedback
reduces distortion and permits the use of
low operating current in the collector circuit. This is essential for a low -noise output signal. The fact that no equalizing network is connected in series with the base also
helps reduce noise.
The low input impedance of the preamplifier permits hookup to all available
ceramic pickups on the market today. Remember, unlike a vacuum -tube amplifier circuit, this transistor preamplifier depends on

Putting It Together. Parts layout, shown
in photo, closely matches the schematic diagram. All resistor, capacitor and transistor
leads terminate at flea clips. If you prefer not
to use flea clips, make all connections by
passing leads through perf -board holes and
soldering underneath perf- board. Twisted
wire leads can be used to connect to ceramic
pickup and amplifier input terminals.
Shielded cables should be substituted if hum
level is high. Also, it may be necessary to
connect a 10 -mf. 6-volt electrolytic capacitor
across the power supply leads (watch polarity ) if preamp taps power from phono's
power supply.
Installation is not critical. Keep leads
short and locate perf -board away from heat.

serve as a test record. Play the recording

It should be evident to every CBer that
the FCC is bent on a real crackdown, for the
monthly list of fines and forfeitures now
runs several pages rather than several lines.
And a quick perusal of the list shows that
next to transmitted obscenities, off -frequency
operation ranks near the top of the pinkticket list.
But there is really no reason why any
CBer should risk losing his license because
of off-frequency operation. For the truth of
the matter is that any communications service shop or CB club shop should be equipped
with a frequency meter.
A frequency check is difficult? Nonsense.
With a frequency meter specifically designed
for CB, such as International Crystal's model
C-12B, it takes but ten seconds to check
each channel. Equally important, operation
is so simple the check could be performed
by a child.
Twenty -three Plus. The C-12B is a hybrid (tube and transistor), battery -powered
frequency meter specifically designed for the
Citizen's Band. It has 23 switch -selected
frequencies plus a spare (the 24th position).
In addition to checking frequency with a
claimed accuracy of .0015 %, the meter
will also measure percent modulation and
the transceiver's RF power output.
The meter is supplied with a separate pickup box (called the PK) that provides a dummy load for the transmitter and acts as an
attenuator when the frequency meter is used
as a precision signal generator. The meter's
direct output provides an unmodulated signal
(for alignment, say) of 100 microvolts; with
the PK box in the circuit, the output at the
end of the PK's test cable is one microvolt.

On The Beat. Block diagram shows how
the frequency tests are performed. The output of a precise crystal -controlled oscillator
is mixed (beat) with the transceiver's output
signal. The difference signal below is first
amplified, then rectified, and the resultant
DC passed to a calibrated meter. The greater
the difference frequency, the higher the
meter reading. This, in turn, is interpolated
into deviation from center -frequency.
Let's look at a practical example. Suppose
you wanted to check out a channel -9 crystal.
Setting the frequency meter to channel 9 produces an internal 27.065 MHz signal. If the
signal from the transceiver were off- frequency by 100 Hz, its output would be 27,065,100
Hz. And when 27,065,000 Hz is beat against
27,065,100 Hz, the output from the mixer
will be the difference between the two frequencies-a 100-Hz beat note.
This is then amplified, rectified and the
resultant DC displayed on the meter as 100 Hz deviation. A special switch is provided
that tells you whether the deviation is above
or below center channel. If the signal from
the transmitter were exactly 27.065 MHz,
there would be no (zero) beat note and the
meter would therefore indicate "0 "
deviation from center channel. The meter is
calibrated from 0 to 3000 Hz deviation, with

column 4 the C -12B's error in Hz. Note
that the error is less than the specified 100
Hz and in many instances less than 10 Hz.
Allowing for interpolation of the meter
scale (which is calibrated in units of 60 Hz),
the maximum error of the model we obtained
would be considerably less than 100 Hz. Frequency drift from the moment of throwing
the power switch to the moment of measurement (a few seconds) was less than 10 Hz,
again keeping total error well within the
claimed 100 Hz.
As far as the mechanical operation is concerned, things couldn't be easier. You feed
in the transmitter's signal, set the mode
switch to RF, adjust the level control until
the meter pointer lines up with a scale mark,
then switch to deviation. The meter then indicates frequency deviation instantly; total
measurement time is less than 10 seconds.
Other Functions. To use the C-12B as a
power meter, you simply set the mode switch
to RF and turn the level control full clockwise. The C-12B then indicates the transmitter's output power, and in the unit we tested
it does so with an accuracy better than the
claimed Vs watt. For example, when the
actual power fed into the unit was 3.0 watts,
the C -12B indicated an input of 3.2 watts.
Since the C-12B's meter is damped, a sustained word rather than a string of words
must be used for modulation tests in order
to permit the meter to rise to peak value. For
example, when the speech input was a long

You can add a Beat -Frequency Os-
cillator to just about any all -band
receiver without digging into the
chassis. All connections are external
but you can get better shortwave
reception with a direct connection.
INSTANT
by C. M. Sranbury II
Many receivers for the general public
have a short wave band but no BFO (beat frequency oscillator). Most hams today use
either Morse code (CW) or single -sideband
(SSB) voice (both of which require a BFO),
and cannot be tuned in on receivers without
a BFO circuit. But there is a solution. Go
to a war- surplus dealer, purchase the lowest
priced longwave receiver he has at hand,
and you're in business.
Here's How. Just about all modern receivers, especially those which are intended
for the general public, are put together using
a superheterodyne circuit (not that there is
anything necessarily "super" about the home entertainment version of it). The signal
from the antenna is picked up by the RF
stage of the receiver
the station's actual
frequency. In the type of set we're dealing
with here, little amplification takes place in
the RF (radio frequency) stage. Instead it
is immediately converted to a fixed intermediate frequency (IF), and usually centers
on 455 kHz (kc). Because this narrow band
of frequencies is fixed, tuned -amplifier circuits can be built much more economically.
Now if you had a receiver intended for
amateur or communications listening, it
would have a beat -frequency oscillator oper-
-at
62
ating very near the intermediate frequency.
The BFO is actually a miniature transmitter
(oscillator) built into the receiver and putting out a microvolt signal. For example,
in Lafayette's brand new HA -700 the BFO
operates at either 452.5 or 457.5 kHz (and
if necessary can be adjusted for any value in
between). When a CW carrier is tuned dead
on, it appears in the IF stage at exactly 455
kHz, beats with that BFO just 2.5 kHz away
and in turn produces an audio note of 2500
Hz (cps). (1 kHz equals 1000 Hz, of
course.) The dots and dashes are then easily
readable (heard as dots and dashes).
What To Do? But we're forgetting
you've inherited a SW receiver without a
beat-frequency oscillator. So obviously what
you must do is add a BFO to your present
receiver. And because you are just a beginner, this must be accomplished in the
simplest way possible. Which brings us back
to that war -surplus longwave receiver. Most
of these are blessed with a BFO which operates at the LW sets' own IF (somewhere
below 200 kHz) and all will tune the SW
rigs' IF. (Be careful -some were regenerative circuits not superhets.) By now I'm
sure the idea is beginning to dawn on you.
If not then consider this little experiment.
-
RADIO -TV EXPERIMENTER
Put the two receivers side by side on a table.
Pick out a station on the SW dial, then turn
the set's volume down to nil but not far
enough to turn the power off. Now tune the
LW receiver to 455. Lo and behold -there
is your SW station.
Why? Well, because every inexpensive
shortwave rig radiates slightly at its intermediate frequency. Whatever it picks up is
rebroadcast at 455 kHz and your longwave
receiver will pick this up. Of course you'll
want maximum IF pickup. To obtain this,
the two receivers should he connected to
a common antenna. And if this still doesn't
provide enough pickup, have a qualified
technician hitch the SW 1F's output directly
into the LW's RF circuit. But we emphasize
the person who does this must be fully qualified. If you try it yourself, the results could
he "shocking." Anyway, in most cases the
common antenna will do the trick.
Pitfalls. Now in setting up this system
there are a few pitfalls to avoid. First be
sure the LW receiver does tune to the IF-
that is, it must have a band covering the 400
through 500 kHz range. Next, be sure the
LW rig you buy is war surplus and not a
new one, otherwise you could wind up paying
more than a regular Ham receiver would
have cost. Sometimes the hand switches on
these old rigs act up, however, for amateur purposes, once the receiver is on that
455 kHz band, you shouldn't care less. On
the other hand, this should knock down that
price still further. For more exact details
on price, pick out the appropriate dealers
from their ads in this issue (and Literature
Library), then write them.
There is one more thing to look out for.
We said that the two receivers should be
connected to a common antenna. But sometimes connecting the SW receiver on the
hookup will badly detune the LW antenna
circuit. If this does happen, simply place
a very small capacitor (not bigger than
50 µµf but the value is not critical) between
the longwave lead and main antenna which
in turn is attached directly to the SW rig.
This effectively isolates the two tuning circuits. This is a must if you decide to connect into the IF amplifier directly.
All Set. So now you're all set for CW
reception. You're also ready to receive
single-sideband transmissions but these will
require much more careful tuning. A SSB
signal is just like one using standard AM
(amplitude modulation) except that one sideband (which you won't miss) and the carrier have been removed. In order to hear
single -sideband voice transmissions in an intelligible manner you must produce your
own carrier within the IF. The BFO, of

comparative strengths unaltered. Then because just about all superheterodyne sets are
blessed with AVC (automatic volume control), you merely have to tune the LW receiver up and down those IF signals until
the desired modulation becomes readable.
However, because of the military rig's own
high degree of selectivity, the amateur station's modulation level will probably be
weaker than normal. To compensate for
this, push the LW's audio gain (volume)
well up.

Pick up a small twist switch with threaded

the cover or housing from your doorbell and
drill a hole through it large enough to pass
the threaded shaft on the switch. Make sure
the switch body inside the housing won't interfere with the bell mechanism.
Remove the wire coming from the bell

one of the pigtail wires on the switch to the
transformer terminal. Then connect the
transformer wire to the other pigtail wire on
the switch by twisting them together and

Each of the 22 numbers represent a prearranged message. And when the sender
hears a responsive hum in his helmet he
knows his message has been decoded. Immune to jamming, the "entry" will be especially valuable for future allied soldiers
who speak different languages, since they
will be able to communicate in code.
Tiny TV. Though digital messages cannot show tactical situations as they happen
on the battlefield, the television picture can.
To send pictures to field commanders behind the front lines, Westinghouse has devised the world's tiniest TV camera. Even
today the smallest space camera weighs up

fashion "shoes" for the foot soldier forced
to parachute -land or drop onto a tree -top
landing mat from a helicopter, Lockheed
borrowed from its moon-landing know -how.
Originally designed to cushion the lunar
excursion modules (LEM) when they land
on the moon, the DynaSorb "shoes" are
fashioned of metal tubing slotted at one end.
Under stress the metal curls in upon itself,
much in the manner of a party noisemaker.
In this way, the new shoes will absorb energy
impact on landing.
In Lockheed's design, a cylindrical tube
is notched at measured intervals around its
base. On impact a cone rises within the tube
and extends the splits which have a natural
tendency to coil. A control ring on the outside of the tube will govern the splitting
rate and the tightness of the coils which bear
the impact. The "shoes" come in a variety
of hardy metals that can withstand Superman stresses.

It's not uncommon these days to run into
people who automatically assume that anything offered as professional equipment is
pure junk. And they do have a point, since
anyone exposed to "professional recorders"
at $29.95 and "professional amplifiers" at
$19.95 could hardly believe otherwise.
This makes it all the more unusual to find
a really professional recorder that isn't touted
as such. Yet the Heath AD -16 is just that
a professional recorder of the type you could
very well find in a broadcast or recording
studio. What makes the Heath a professional
recorder is that it originally started out as a
Magnecord.

It appears that Heath took an already existing "professional" recorder, reduced it to
its component parts, and eliminated some
tricky equalization adjustments that could

Heath then added a construction manual,
packed the unit in a shipping carton, and
offered it at a savings of almost $200 below

we can determine, the major difference between the Heath AD -16 and the original

KNIGHT-KIT SAFARI III
23- Channel Portable
CB
Transceiver
The latest addition to Knight's line of CB
transceivers really offers something different
and unusual, which, although it may not
appeal to all, will certainly find a home with
some.
The Safari III looks much the same as any
other solid -state rig, with the usual PTT
microphone. But the difference is that the
mike is in reality a speaker /mike; release
the PTT switch, and the sound is right out
there in front of your face. Ambient noise
too high? Just move the mike next to your
ear and literally pour the sound down the
canal.
Priced at $84.50, the Safari III is available only as a semi -kit. To insure that the
transmitter meets FCC regulations, the entire transmitter section is factory -wired,
tuned, and adjusted. The builder makes absolutely no adjustments to the transmitter
section during or after construction. Building the kit consists, essentially, of mounting
the receiver and modulator components on
the printed circuit board (the transmitter
and receiver utilize the same board). And
output jack is part of printed -circuit assembly, entire transceiver can be removed as unit for service and adjustment.

with the exception of the front panel controls and power-cord socket, there are few
components which are not mounted on the
PC board.
Push And Solder. Construction is not difficult since most of the work consists of
pushing the components through the matching holes and soldering. Typical of Knight kits utilizing printed- circuit wiring, the
printed wiring in this unit has an "anti -run"
coating that exposes the copper foil only at
the point to be soldered. Even if you use
excessive heat or solder, the solder will be
confined to the exposed copper (a good feature for beginners and oldtimers alike).
The only point at which extreme care must
be taken is with the crystal- socket -to-selectorswitch wiring. Although the transceiver is
normally supplied with but one set of crystals, there are sockets for full 23-channel
operation. That means 46 crystals, and,
therefore, 46 leads running to the selector
switch. While the selector switch wires are
color -coded, the same color is used several
times. As a result, extra care must be used
to insure that the right socket lead goes to
the right selector terminal (yep, we goofed).
Ready To Go. When the kit assembly is
completed you're in for a real surprise. For

Limited in antenna space? Here is a low
cost three -band system that will fit the average backyard and is ideal for the novice
amateur operator since it's designed for 80,
40 and 15 meters.
The system is constructed with 300 -ohm
television twin lead and consists of a 40- and
80 -meter dipole with the same feed line at
the center. The entire system is "shrunk"
to 100 ft. by bending the 80 -meter section
back 12 ft. at each end. There is no noticeable sacrifice in performance.
Construct the antenna to the dimensions
in the diagram, using copper -clad steel TV
twin lead. Start by cutting two 50-ft. lengths
of twin lead and attaching an egg insulator
to a single insulator to form the center feed
point.
From each outer end, measure back 12 ft.
toward the center, then remove a 5 -ft. section of conductor from one side of the twin
lead. Attach the feed line and the system is
ready to go on the air.

Either 72 -ohm coax or twin lead may be
used for feeding the system. A 72 -ohm twin

it will also work fairly well on 20 and 10

ammeter
for
experimenters
by James A. Fred
Measuring the current drawn by an AC- powered circuit will often pinpoint those obscure defects in power transformers and other parts.
One of the benchmarks that separates the
tinkerer from the serious electronic experimenter is an AC ammeter. Everyone has a
VOM or a VTVM, but very few tinkerers
ever measure AC amperes. There are many
times when the ability to measure current
will save the day on a repair job or an electronic design project.
To keep from draining the bank account
an ammeter should be a multi -range job. I
started with a 0 -50 AC milliammeter simply
because I had acquired one in a trade. You
can usually pick up a good used one from
Bigelow Electronics, P. O. Box 71, Bluffton,
Ohio 45817 or buy an inexpensive new one.
There are two general types of AC milli ameters in use today. One is called an iron
vane type while the other is simply a DC
movement with a rectifier to change the ACcircuit current to DC -meter current. The second is referred to as a rectifier -type ammeter.
For the experimenters the inexpensive iron vane type is preferred and is the one used
here.
Since the meter has a full -scale reading of
50 ma it is best to make it read three different values of current beginning with a five.
FEBRUARY- MARCH, 1967
The selected ranges were: 0 -50 AC ma., 0500 AC ma., and 0 -5 AC amperes.
It's The Shunt. You can make any range
current meter that you need by following
these directions. To make a milliameter read
higher values of current it is necessary to put
a shunt across the meter -you put a lower
value resistance in parallel with the metercoil resistance. To make the 0 -50 ma meter
indicate 500 ma select the shunt so that 50
ma goes through the meter and 450 ma goes
through the shunt. On the 5 ampere range
there will be 50 ma flowing through the
meter and 4.950 amperes through the shunt.
Internal Resistance. To find the resistance of the shunt you must know the internal resistance of the meter. To find this
value connect the unknown meter in series
with a battery and a rheostat. Adjust the
series rheostat until the meter reads full scale.
Connect a second rheostat in shunt (across
the meter) and adjust the shunt until the
meter reads half scale. See the drawing for
this circuit. Disconnect the rheostat from
across the meter and carefully measure its
resistance. This value of resistance is equal
to the resistance of the meter.

In this formula R equals the shunt resistance. Rn: is the meter resistance and n is the
scale multiplication factor. For example let's
convert the 0 -50 ma meter to read 0 -5 amperes. The scale multiplying factor is 100.
If the meter resistance is 100 ohms then:
R
= (100-1) =
1.01 ohms.
The 1.01 -ohm shunt will have to carry
4.950 amperes at the full scale reading. By
using the power equation
P=1R
we find that we need a 27 -watt resistor. A 50watt adjustable resistor will work nicely

be necessary to make it from copper or
nichrome wire. Remember it will be necessary to multiply the scale readings by 100
when using this shunt. You can use the same
formula to figure other values of shunts.
Calibration. When you get ready to
check the calibration of your meter it would
be wise to have another meter to use as a
standard. Connect the standard ammeter,
your meter, and a load of the proper size in
series. (See the circuit diagram for this step.)
Adjust the load for 2.5 amperes through the
standard meter and adjust the shunt's resistance until your meter reads 2.5 amperes.
Recheck the meter with a 5-ampere load. A
four -position single -pole switch is wired, as
shown, to select the different meter ranges.
A meter short -circuit position is included because it is good practice to always short out
the meter until you are sure of your circuit.
A phenolic board is used to mount the switch
and resistor. The meter is mounted first in
the aluminum box and then the phenolic
board is mounted to the meter by the meter
studs. The photographs show how everything
goes together.

Since there was no room in the meter box
for an AC receptacle or fuse holder I decided to make an additional box that could
be easily fastened to the meter box. The end

that would match this would be great, but
none are available. The nearest standard -size

mounted on the front of the box-on the

Many defects in electronic equipment can
be detected with an AC ammeter. Some of
these are: shorted or partially- shorted power
transformers, bad tubes, and bad or leaky

safe rule -of-thumb is to install a fuse rated

The Tape -Slide Synchronizer is an electromechanical device which automatically
actuates the slide-changer mechanism at the
exact instant dictated by the commentary
on the magnetic recording tape-thus
assuring perfect synchronization of commentary and slides at all times. A taped
slide -show commentary has a number of
advantages over live, off -the -cuff commentary. One advantage is that important facts

FEBRUARY -MARCH, 1967
Early units were difficult to use. Some
required conductive marks to he placed on
the tape, others used a high -level audio
signal in the sound track (which was objectionable as it could be heard). In order
to overcome the objection of the noise from
the sync signal, one unit operated on the
complete absence of sound on the tape. A
four-second (or longer) silent period would
activate the slide- changer mechanism. This
system was workable with monaural tapes
but it was difficult to record the commentary
without pausing, thus causing unwanted
slide changes. Some success was also had
using inaudible (ultrasonic) sync signals.
For Stereo Tape Recorders. With the
o- and tonr -track stereo-tape
advent of the
record and playback equipment the disadvantages of the early units were automatically eliminated as the commentary could
be recorded on one channel and the sync
signal on the other. On playback the sync
signal would operate the slide changer via
the switch in the synchronizer. But even
%ith thi, there were relay contact problems.
A Unique Circuit. This Tape-Slide Synchronizer is solid state. Using the unilateral
SCR (silicon -controlled rectifer) alone will
pass only one half of the AC (sine wave)
power -still requiring a relay to switch on

and o/i the AC to the shaded -pole induction
motor-which normally powers the semiautomatic slide changers. By using the SCR
with a diode bridge circuit both halves of
the 60-cycle (Hz) power are passed and the
relay can be eliminated. Another way to
eliminate the relay is to use two SCRs in
inverse parallel but this is more expensive.
Originally this Tape -Slide Synchronizer
was used with a stereo record -playback tape
deck with only one power amplifier and
speaker -for the commentary channel.
The three-stage transistor amplifier operates the SCR circuit. It provides plenty of
gain for use with the tape deck and even a
small crystal microphone can be used to
operate the slide changer and put a sync
signal on the tape.
SCR-Diode Bridge Switch. The heart of
this unit is the SCR -diode bridge switch
the basic switch circuit is shown top right.
The SCR has high resistance between anode
(A) and cathode (C) when there is no signal on the gate (G), and no AC can flow
through the diode bridge to power the motor

-it is off.
When the gate of SCR1 is made positive
(by a positive -going signal between gate and
cathode) the resistance of SCR1 becomes
very low between anode and cathode (it
conducts) and the motor runs.
Conduction of both halves of the ACpower sine wave is brought about as follows:

flows through motor M1, then through D5
from A to B, through SCR1 to D2 (from D
to C) back to the other side of the line
(Y).
When the positive cycle of the AC line
is at Y, current flows through D3
(from
C to B), through SCR1 to D4 (from D
to A), then back through motor M1 to the
other side of the line (W) .
In like manner, the sync signal from the
output of the tape recorder, when rectified
and applied as a positive ( +) pulse to the
gate of the SCR -diode bridge, switches the
slide-changer motor.
Solid -State Synchronizer. The complete
schematic wiring diagram, including that for
the slide changer, is shown below. Remote pushbutton S2 is used to operate the

The output of the oscillator is also fed to
the stereo -recorder input (from J3) and it is
recorded as the sync signal on the control
channel of the tape. The commentary is
recorded in the usual manner on the other
channel of the tape at the same time.
During playback the output of the control

J2) to the input of the second stage of the

(without power amplifier) is available, there
is ample amplification for both recording
and playback of the sync signal on the control channel using either the microphone or

necessary amplification. During recording

light, I'd taken the ocean drive (to pick out
a parking place in advance) and no sooner
was I committed to this route than fog commenced to roll in. At 8:30 I crawled along
at 10 per, still a good 15 minutes from Ora's
beach house. I tried to find some jazz on
FM, which is scarce along this coast. Nearest station is on the island, 50 miles away,
and it wasn't making it through the fog.
I switched over to CB just as Ora put
her carrier on and pinned my needle. "This
is Unit 2," she said softly. "Unit 1, where
are you?" A sweat trickled down my spine.
I came back, "Crawling along in this darn

I'm driving from Cometland toward Ora's.
They're only a mile or so behind me on the

further south."
Yours truly pushed a little harder on that
accelerator. "Sure you will."

Nat kept it up. "I'm not fooling, Unit 1.
They've turned Cometland into a base and
more spaceships are landing right now. You
can hear them coming in from here." There
was a loud hum in the background.
I yawned a little. "So you brought your
shaver with you. And don't forget the last
CB'er who sent a phony distress got two
years in the pen."
It was her turn. "Maybe he's not worried
because the license is in your name. Anyway, man, you'd better make it here within
five minutes."
"Just passed the lighthouse, Ora. That
makes it less than a mile." The fog horn
was really blowing up a storm and now the
visibility had dropped to absolute zero. I
slowed down, thought about that license bit,
and began to sweat a little. "Unit 3, this is
Unit 1. As licensee I've just cancelled your
operating privileges."

A moment of quiet and then he returned.
But now that hum was really tremendous.
"One of their ships is right overhead. I think
it's after me. The thing is draining power
from my batteries." His signal dipped appropriately. "Now my car has stalled and
I can't move." With the most tremendous
panic you ever heard come out of a CB
receiver, "They're landing on the road in
front of me." He faded out completely.
Ora took over the channel. "Hey, Unit
1, it's now 8:45. Do you figure those astronauts out there in the fog would treat me
better than you guys do ?"
I inched around a final curve by following
the shoulder of the road. "Wouldn't bet on
it."
"Well, I may get the chance to find out
because there's a big bright light coming up
over the northern horizon."
I put myself back on the air quick. "If
Nat's arrived there first, both your operating
privileges are cancelled."
Thirty seconds of dead air.
"Nobody here except me, yet. But if he's
kidding, how come we're the only two people on the air?" She laughed ever so slightly,
almost nervous. "Anywhere, any band."
Enough! Between the fog and Nat's phony
distress, I was really hung up. "All right,
girl, if you really want to play, standby." I
switched on my general coverage converter
and began working down through the international SWBC bands. 16 and 19 meters
were absolutely dead but on 15,016 kHz
some bird with a phony accent and a made up language was sending messages. I returned to CB and hit the airwaves again.
"Nat, it's also illegal to transmit off the

Silence.
On 15,016 those weird messages continued to flow. I moved on down through 25
and 31 meters which were also blank. Static
showed up around 6 MHz but still no stations. A funny feeling crept into the pit of
my stomach.
The AM broadcast band was also silent.
I put my CB transmitter on in a hurry.

Propagation
Forecast
Starting this issue we have made our propagation forecasts even easier for shortwave
listeners to use. If you are DXing at a certain hour, simply run down the left -hand
column in the Forecast table until you find
the appropriate time slot, then look across to
the right and determine what is available on
which bands for each major area in the
world. Bands in brackets are promising second choices. Time intervals are for your local standard time. If you live in the Central
Standard Time (CST) zone then the Time
column in our Forecast table is CST.
On the other hand, if you are listening for
one particular part of the world only, check
February /March
1967
the Peak DX Periods table first to see what
time the best DX is available from that area.
Follow this time slot across in Forecast table
to determine the best bands. If you live in
the CST zone, use the Eastern column but
deduct hour.

To use the table put your finger on the region you want to hear and log, move your finger down until it
along side the local standard time at which you will be listening and lift your finger. Underneath your
pointing digit will be the shortwave band or bands that will give the best DX results. The time in the above
propagation prediction table is given in standard time at the listener's location which effectively compensates for differences in propagation characteristics between the east and west coasts of North America.
However, Asia and the South Pacific stations will generally be received stronger in the West while
Europe and Africa will be easier to tune on the east coast. The shortwave bands in brackets are given
as second choices. Refer to White's Radio Log for World -Wide Shortwave Broadcast Stations list.

t,i 1011f ofIhti
open road
By Bob Angus
Like peas and pods, tapes and cars are pretty
much inseparable these days. For the cartridge
player has at last found a home for itself
countless highways and byways throughout the nation.
-on
If there's a Ford in your future, you may
well find a stereo tape- cartridge system in it.
And Ford's not alone. For today's boom in
car -cartridge players is so big it's second only
to the craze for color TV. Some industry
optimists even see highway hi -fi as the greatest thing to hit the recording industry since
the LP.
But what's the big deal about car-cartridge
players? (They have, after all, been around
for more than a decade.) And given four
tracks (and often eight) at a tape speed of
33A ips (sometimes 1%), the question is
whether such players produce any stereo
worth having. In short, just how bad is
highway hi-fi?
The answer, as well see shortly, depends
FEBRUARY -MARCH, 1967
on what we define as hi -fi and which particular highway hi -fi is under discussion. For
the fact is that at the moment, there's not
one but three major and several minor systems for putting stereo tape in your car. The
majors include the Fidelipac system, developed in 1956 by George Eash; the Lear-Jet
system, introduced in 1965 and espoused by
Ford and RCA Victor; and the Norelco system, introduced in 1964 but only recently
adapted for automotive use.
Also clouding the picture is a major battle of-the -systems. At the moment, the industry
is going through a set -to reminiscent of the
one between RCA Victor (with its 45s) and
Columbia (with its then -new LPs) over a
decade ago. Significantly enough, no system
89

seems to have a clear technical superiority.
Instead, each seems able to provide satisfactory sound reproduction in the car, and at
least two of the three have plenty of music
available to match most tastes. All three can
move from car to home, so you can play
the identical cartridge in your car or your
living room. And all three, in large part,
became possible as the result of the development of reliable, low -cost transistors.
Fidelipac. The Fidelipac cartridge features an endless loop of tape wound around
a hub inside a plastic shell. The tape feeds
from the pack's center, travels past notches
cut in the plastic to accommodate a playback
head and pinch roller, then rewinds at the
outside of the tape pack. The cartridges are
recorded at 33/4 ips in four -track stereo and
sell at prices ranging from $2.95 for about
15 minutes' playing time to $9.95 for over
an hour's worth of music. Prices for players
run from about $70 to $140.
Fidelipac players are sold by such manufacturers as Craig Panorama; SJB, Inc.;
Telepro Industries; Trans -World, Inc.; Midland International; Viking of Minneapolis;
Muntz Stereo -Pak; Auto -Sonic; Nu-Vox;
Audio Stereo; and Metra Electronics. These
and other manufacturers provide a wide
range of music from the libraries of MGM,
Command, Verve, ABC Paramount, Westminster, Pickwick, Audio Fidelity, Mercury,
Dot, Elektra, and a host of other record
companies. Prices for the players themselves
vary, depending on whether speakers are
included, whether the unit plays back
through an existing car radio, whether AM
or FM radio is included, and so on.
In view of Fidelipac's lead time over the
other systems, it's hardly surprising that an
estimated 70 per cent of the car -cartridge
players now in use utilize this system. All
of these units were bought for cars already
on the road. At the moment, Fidelipac also
accounts for better than 60 per cent of
cartridge sales.
Lear-Jet. Lear-Jet units are to be found
mainly in current -model Fords, Mustangs,
Thunderbirds, some Mercurys and Lincolns.
The cartridge is about the same size and
shape as the Fidelipac, and it is also recorded
at 33/4 ips. However, recordings are in eight track rather than four -track stereo. Further,
unlike the Fidelipac four -track units, a pinch
roller is included in each cartridge. Prices
for recorded cartridges are comparable to
Fidelipac's, and the catalogs include many
of the same titles plus albums from RCA
Victor, London, Decca, and Capitol. Player
prices are comparable to Fidelipac's.
In addition to the units Ford is installing
in its new cars, players are available from
Lear -Jet and Soundex Corporation for cars
already on the road. And Lear hopes to
entice General Motors into joining Ford and
Chrysler into putting its players in their new
cars. "With the auto industry turning out
over nine million cars a year," a Lear spokesman said recently, "it looks like something
between 15 and 20 per cent of these new

cars will have stereo tape playing systems."
Norelco. With all this activity, another
cartridge system would seem to have little
chance of gaining a foothold. Nevertheless,
Norelco last year introduced a dashboard
harness for its battery-operated portable
tape- cartridge recorder and thus made a bid
to capture part of the growing market. And
the real breakthrough came when Norelco
managed to persuade Mercury Records,
Minnesota Mining, General Electric, Sony,
Aiwa, Concord, Panasonic, and 31 other
firms to adopt its system. Norelco -type players now cost from $70 to $100 and, unlike
the others, are powered by self- contained
flashlight batteries.
The Norelco system centers around a two hub cartridge roughly a fifth the size of the
other two. Similar to a design that was
introduced by RCA in 1959, the Norelco
model utilizes 1/2-in. tape recorded at 17/a ips.
At the moment, recording is twin -track
mono only -but the developers plan to introduce compatible four -track stereo soon.
Blank cartridges, which cost from $2.65 to
$3.25, hold 45 minutes of uninterrupted
recording and are available from Norelco,
Mercury, and Minnesota Mining. Prerecorded cartridges will cost about $4.95 for
32 minutes (about the same price as a
stereo LP).
Among the machines which now fill the
Norelco car harness are the Norelco CarryCorder ($89.95), the Mercury TS8000
($89.95), the Wollensak 4100 ($89.95),
and the General Electric M8300 Lively Set
(about $90). Both Norelco and Mercury
project four -track stereo models using 1/2-in.
tape at prices around $150.
The versatility of a 3 -lb. recorder that
operates equally well in a living room, at
the beach, or under the dashboard-plus the
fact that the owner can record his own fare
-are the major assets of the Norelco system. Of course, given the know -how, it is
possible to record Fidelipac tapes on a conventional four -track recorder, then load the
tape into a cartridge. And Soundex now
offers a Lear -Jet record /playback deck,
while Roberts has introduced eight-track
cartridge record /playback as an extra feature
on its model 1725 -8L recorder.
But for the most part, Fidelipac and Lear
users are limited to commercially- recorded
cartridges. At press time, there were only
50 prerecorded Norelco -type cartridges-all
monaural, and all from the Mercury, Philips,
Smash, Wing, and Limelight catalogs. But
more were promised.
SJB, Tenna. For those who can't make
up their minds as to which of the three
major systems they prefer, there are a number of hybrid compatible units on the
market. SJB's line, for example, includes six
models, ranging in price from $100 to $170.
The model ST308, at the bottom of the scale,
comes with indicator light. For $130 you
have a choice of model ST408, with indicator light and autpmatic light or model
603M/48, an all- chrome unit with speakers,
adjustable bracket, cigarette lighter plug, and
carrying handle. Another $10 adds FM
radio to the ST308. Shell out $170, and
you have a choice of two compatible
tape -FM units, models ST408 /FM and
603M/48/FM.
Still another compatible unit comes from
Tenna Corporation. Said to be the least expensive on the market, it sells for $69.95
and features automatic sensing of cartridge,

Homeward Bound. With most of the
cartridge problems licked, manufacturers are
beginning to design players for the living
room (and a few models which can be connected directly to a component hi -fi system).
Accepting Lear-Jet cartridges are Soundex's
$80 player, RCA's Mark 8, and models from
Lear -Jet, Roberts, and General Electric.
Fidelipac units are available from Muntz
Stereo-Pak, Telepro, SJB, and others.
Among the four -track home players are
Telepro's Satellite II; and Muntz's A -HW -1,
AR -300 and AR-400. The latter two are
complete home -entertainment centers with
record changer, amplifier and tape- cartridge
handler. The AR -400, mounted in a cabinet,
also contains two speaker systems, while the
AR-300 is the heart of a stereo compact
system.
Installation. In theory, some of the
prices quoted by manufacturers include installation of the player in your car. In practice, you can save money on virtually any
model by installing the unit yourself. Just
how much work is involved depends on the
type of unit you buy. The Norelco models,
for example, simply slip into their harness
with no additional work required. Those
which operate through an existing car radio
fit in a bracket mounted below the dashboard. (You'll also have to connect the
player output to the radio amplifier -often
merely a matter of inserting a jack.)
The most complicated to mount are the
stereo models with speakers, since you'll
have to cut holes for the speakers in your
door panels. Which tools you'll need depends on the type of padding your car has
inside the door. Speaker brackets and protectors usually are supplied with the do -ityourself kits. Wiring from the player to the
speakers is fairly simple, and consists of
tucking the wire up under the dash, then
running it through the panelling to the point
where it meets the door frame.
Sound -Box -On- Wheels. Where does it all
lead? Surely eight -track tape must have
a significantly higher tape hiss than four track? And isn't it logical to expect 33/4-ips
or 17/8 -ips recordings to sound inferior to
71/2 ips? Actually, there's an aural trick involved. Tapes that sound very ordinary in
a living room sound very good (if not excellent) in a car. The trick is similar to the
one which permits 31/2 -in. speakers in stereo
headphones to produce such startling bass
tones.
In short, much of the system's success
stems from the setup itself; you're enclosed
in a relatively small space with two speakers
and are in effect smack in the middle of a
veritable sound -box-on- wheels. At the same
time, road and traffic noises mask any imperfections in the recording or the equipment so that you hear
think you hear
strikingly good sound.
In the living room, however, it can be

Unlike both Fidelipac and Lear -Jet systems,
Norelco's cartridge contains two separate
reel hubs that unwind and wind in
standard fashion. Cassette (seen in hand

World -Wide Shortwave Stations
With
this copy of White's Radio Log
at your operating desk you will be
able to quickly identify and spot over 300
international broadcasting stations -the majority of the currently active stations being
monitored by our readers and by the RADIO TV EXPERIMENTER monitoring station, DX
Central.
Each issue brings you a completely revised and updated version of the shortwave
section which reflects new frequencies and
schedule changes by the broadcasters. Our
list may lack only one thing, that is your
own personal listening experiences.
Yes, we find that the best way to compile
a listing of active shortwave stations is to
rely upon the latest reception loggings of
our readers and, although we know that
thousands of our readers make use of
White's, only a handful of readers take the
trouble to send us a copy of their loggings.
Naturally we don't expect to hear from each
and every reader for each and every issue,
but we would like to hear from you at least
once in a while. Why not let us know when
you stumble upon particularly difficult staetion to log, or when you come upon a reCall

sustained 400 Hz and 15 kHz tones for both
azimuth and bias adjustments, using the
built -in VU meters as indicators. For those
who prefer it, an instrument alignment procedure is described, although it is neither
easier nor better than that with the test tape.
How It Performed. The actual frequency
response of the AD-16 is shown in Figs. 1
and 2. Although the response "wavers," it is
well within Heath's specs which are given
in the table. (The "waver," by the way, is
normal with professional recorders that don't
attempt to get a "ruler flat" frequency response by excess equalization at the expense
of substantially higher high- frequency dis-
tortion.)
The kHz THD (total harmonic distortion) was right on the button of Heath's
claims. In fact, a record input level that
1
exceeded 0 VU did not noticeably increase
the reference distortion of 1.5% THD, even
.,1,1,,,,11,,,,,,,
-at
THD).
The AD-16's price of $399.50 represents
only the recorder; the walnut base is an optional extra at $19.95. For additional information write to Dept. EB, Heath Co., Benton Harbor, Mich. 49023.

right through the case.... If desired, melt a
hole opposite the adjusting screw of C5 -so
you can change frequency without removing
the transmitter from the case.
Checkout. Insert the battery into the clips
-get the polarity right -close the case, place
an FM receiver near the transmitter, and
place the mike near the receiver's speaker.
As you tune the receiver you can't miss the
transmitter's frequency, the feedback will be
unbearable. To change the transmitter's frequency, adjust C5 until there is no interference from strong FM- broadcast stations.
Protecting yourself. To use the Tie -Spy,
clip the mike to your tie, place the transmitter
in your trouser's side pocket, and run the
antenna around your waist under your belt
or under the back of your shirt, or wherever
you prefer. The effective transmitter range
will be about 25 to 50 feet. Don't try to
speak directly into the mike as the gain is
very high and the modulation will severely
"pop" -the gain is designed to pick up voices
from one to three feet. Naturally, the better
the mike the better the reproduction.

another story. Played through their own
speakers most cartridge systems sound like
table -model FM radios. Bass is not really
adequate by audiophile standards, and treble
has been boosted to provide a slightly unnatural sound. Played through a component
system, Fidelipac, Lear, and Norelco cartridges all sound somewhat better -though
none is the equal of a good 71/2-ips reel -toreel tape.
The best sound comes from Fidelipac (we
sampled some of International Tape Cartridge Corp.'s Command titles), which provides generally good and full bass response
through a big speaker system. Mid-range
is accurately reproduced, as is treble. We
found only a slight mellowing of the upper
ranges, compared with a disc copy of the
same music. The Lear-Jet system produces
a similar frequency response (on the basis
of RCA Victor recordings by Morton Gould,
the Boston Pops, and Peter Nero), but there
is a definite increase in tape hiss and a slight
accentuation of treble response compared to
Fidelipac.
table -model player also accepts Nor elco cassette. Lid exposes speaker grille.
This
Norelco's I %B -ips tape has slightly less
audible tape hiss than Lear-Jet, but a slightly
less natural treble sound as well. At the
same time, Norelco's bass tones are not as
clear or crisp as Fidelipac's (tests were made
with cartridges recorded from Command
discs).
Wow and flutter, however, which used to
bedevil reel -to -reel slow -speed recordings,
are inaudible on all these systems. And
while none of these systems offers a hi -fi
alternative to a good component disc- or
tape-reproducing system, one significant fact
remains. For the truth of the matter is that
all can produce excellent results on the
road.

The Body's Ills
Personal Hi -Fi

Continued from page
J2 are mounted directly on one metal panel,
and the stereo headphone jack (J3) is
mounted directly on the other metal panel
no insulating washers are necessary. Resistors R1 and R2, and transistors Q1 and
Q2, are all mounted by their own leads, and
no spaghetti (insulating tubing) is needed if
you keep all leads well apart. When soldering the transistor leads, use a pair of long nose pliers as a heat sink.
How It Works. The PS -15 low- voltage
DC source feeds a current through the piezoresistive elements in the phono cartridge. As
the stylus rides in the stereo record grooves,
the piezoresistive elements are flexed and
stretched and act as rapidly varying resistances. The varying currents from the cartridge are given one stage of transistor AF
amplification in the PS -15 unit.
The output from the PS-15 is fed into the
input of our little headphone driver and
given another stage of transistor AF amplification to drive the stereo headphones. The
two 2.2K (2200 ohms) resistors (R1, R2)
provide base biás for Q1 and Q2; you might
experiment with other values for best results
with your particular transistors.
The amplifier is turned off simply by pulling the headphone plug out of the jack.

ulus blocks pain stimuli coming from other
parts of the body and prevents their traveling on to the brain. Still experimental, it
promises to ease suffering now relieved only
by narcotics or dangerous operations.
Another remedial operation that can be
ruled out is the one often necessitated by accidental swallowing of a ferrous object. Gen-
-
eral Electric engineers have come up with a
gadget that has already removed a padlock,
a coffee -can key, coins, pins, dental burrs,
hypodermic needles, and metal toys from innocent human tummies.
About 30 in. long and IA -in. in diameter,
the new wizard consists of a stainless steel
cable in a plastic tube and ends with an iron
tip. When the magnet at the end of the control cable is slid forward until it touches the
iron tip, the tip magnetizes. When the permanent magnet is retracted into a magnetic
shield, the tip loses its magnetism.
An important breakthrough, the new instrument can retrieve foreign objects in a
matter of two to three minutes. No anesthesia is needed, and a general practitioner requires the help of only a fluoroscope.

and J2 are added to the PK -522
amplifier to make this simplification of
operation possible. Volume control R1 is
set to about its mid -range position for this
setup.
Shock Hazard and Grounding. The yellow lead of the output transformer was
grounded to the positive (+ ) battery terminal in the original PK -522 circuit. To
completely eliminate shock hazard the
printed- circuit foil was cut leaving the secondary ungrounded as shown at X in Fig. 2.
A separate transformer power supply (T2R2 and C3) provides DC for the amplifier
eliminating possible shock hazards from this
source. To prolong its life, R3 is used to
reduce the light output of the pilot lamp.
The value of C3 must be at least 1000 mf
as it holds the power supply voltage on the
amplifier for good operation, after the AC
supply to T2 has been cut off by the motor driven cam switch (S4) in the slide changer.
Construction Details. Placement of parts
is not critical. And using subassemblies for
the amplifier, SCR switch and the amplifier
power supply makes for a neat and compact
unit which should be easy to service if this
should ever be necessary.
The photo of the under side of the chassis
(Fig. 3) shows the location of parts. The
PK -522 amplifier is shown fastened to the
right side of the chassis box on 3/a -inch
stand -off insulators. These can easily be
made from test-lead handles or banana -plug
insulators.
The SCR -diode bridge switch (SCR I, Z1,
D1, R2 and C4) is mounted on a phenolic
panel and fastened to the left side of the
cabinet with 1/2-inch spacers. The power
supply (Z2 and R3) is mounted on another
small phenolic panel which is then attached
to the bottom side of the chassis box with
1/2-inch spacers. T2 is mounted direct to the
lower side of chassis as shown.
Fig. 4 is a photograph of the Tape -Slide
Synchronizer and shows, in conjunction
with Fig. 3, the location of the other

components.
Cables. The two -wire power cable which
connects the slide- changer unit to the Tape Slide Synchronizer has a 4- contact plug
number Jones P- 304 -CCT on one end which
mates with the original Jones 4- contact
The female Cinch-Jones chassis socket
S- 304 -AB shown on the chassis is not essen-
tial unless the original remote pushbutton
cable operation is desired.
The shielded wire connecting the synchronizer unit with the recorder has a miniature
phone plug on one end and whatever type
fittings needed (on the other end) to mate
with the input and output of the particular
recorder used.
Conclusion. The Tape -Slide Synchronizer
can be used with any stereo -tape record/
playback unit and practically any remote pushbutton- operated semiautomatic slide
changer. Adequate gain is available from
the 3- transistor amplifier to operate with the
preamps of most stereo tape decks. Furthermore, if desired, a small crystal microphone
can be plugged into the synchronizer's input
for voice operation of the slide changer and
simultaneous recording of the sync signal on
the tape.
Since the Tape -Slide Synchronizer is all
solid state there are no relays, contacts or
moving parts to wear out. This unit has been
in service for nearly a year and has required
no service of any kind to date.
Perfect synchronization of commentary
and slides is assured at all times because the
sync pulse and commentary are recorded on
a single 2 -track tape.

C -1 2B
Continued from page 58
"wo- o -of," or "hello-o -o -o," the C -12B indicated somewhat in excess of 90% modulation. The actual scope value under these
conditions was 100 %.
Summing Up. The C-12B frequency meter, functioning as a frequency meter, precision signal generator, RF power output meter, and modulation meter, essentially performs all the tests required to insure a CB
set is completely legal in its operation and
that it is performing at optimum efficiency.
We therefore recommend it as a must -have
item for any shop doing CB servicing.
The C -12B is priced at $300.00. Additional
information is available from Dept. RF, International Crystal Mfg. Co., 18 N. Lee, Oklahoma City, Okla. 73102.
