DESCRIPTION
The FM 60A is a rugged, compact communica-
tions unit designed to operate from any 6 or 12
volt d.c. (negative or positive ground) vehicle
power source or a 117 volt a.c. 50 to 400 cycle land
station power source.
The FM 60A is designed for narrow-band phase/
frequency modulation (5KC deviation) opera-
tion in the frequency range of 25 to 54 megacycles.
The receiver and transmitter sections are designed
for single channel, crystal controlled operation.
The transmitter and receiver may be operated on
the same channel (simplex frequency assignment)
or on different channels (duplex frequency assign-
ment).
All necessary components for 6 or 12 volt dic.
operation of either polarity or 117 volt AC opera-
tion are built into the basic communications unit.
The proper circuitry is selected by the wiring of
the external power plug thereby eliminating the
need for jumpers or switches in the basic unit. The
FM 60A may be interchanged in any 6, 12 or 117
volt system without modification and without re-
gard to battery polarity.
OPERATING INSTRUCTIONS
CONTROL FUNCTIONS:
There are only three external controls. The left
knob is a conventional volume control; the right
knob controls the squelch. By turning the squelch
knob clockwise, the sensitivity is increased and as
this control is advanced clockwise, a point will be
reached beyond which a loud hiss will be heard.
However, there is a setting before this point where
the receiver is operating at optimum sensitivity in
a squelched (noiseless) condition.
The three-position power switch on the panel
is “OFF” in the extreme left setting. In the center,
or “STDBY™ position, the receiver only is operat-
ing, and the transmitter filaments are turned off.
In the “OPERATE” position, the receiver remains
“ON” however the transmitter filaments are also
“ON.” After a warm-up period of about 20 seconds,
the transmitter is ready for operation by depressing
the “push-to-talk” switch on the microphone.
The “on-off” pilot lamp located to the left side
of the power switch lights when the set is turned
on. The pilot lamp on the right side lights only
when the transmitter is on the air.
When the push-to-talk microphone switch is de-
pressed, the transmitter section of the communica-
tion unit is actuated, the red transmit lamp lights
and the receiver is muted. Release of the push-to-
talk switch, turns the transmitter section off, ex-
tinguishes the red transmit lamp and actuates the
receiver section. This sequence of events is in the
“OPERATE” position of the power switch. When
this switch is in the “STDBY” position the micro-
phone push-to-talk circuitry is inoperative.
The use of the “STDBY” mode of operation is
highly recommended where long periods of listen-
ing only is expected as lower power drain together
with longer transmitter tube life will result.
The FM 60A is a highly efficient receiver-trans-
mitter and will provide reliable communications
over great distances if properly used. Radio operat-
ing is an art that is easily learned with practice.
The limitations of a system installation in any
particular area may be learned through use. Every
system, regardless of its frequency or power, will
have some locations where it is not possible to
communicate. However, within its range, trees,
buildings, small hills and similar obstructions will
have little or no effect on communications. The
range of a system is dependent on a few important
factors, such as location and height of base station
antenna, power, and nature of surrounding terrain.
The use of a half-wave rather than a quarter-wave
base station antenna is highly recommended in all
installations for best possible performance.
Assuming that the most efficient installation of
the FM 60A is made, one important consideration
remains. This is correct operating procedure and
a few important notes in this regard are:
1. Before transmitting, listen to the receiver and
make certain no one else is on the channel.
2. Let the mobile operator get in the practice
of calling the base station for instructions. Since
the base station is in a known, fixed location, the
mobile operator can call when he knows he is in
a good location.
3. Show each mobile operator how radio ac-
tually helps him in his work by eliminating doubts
about delivery, reducing unnecessary travel, etc.
4. If you are trying to contact a mobile unit
from the base station, remember that he may be
in a poor radio-location, he may have both hands
busy in heavy traffic, or he may have stopped in
the local diner. If you do not contact him after one
or two quick calls, wait a few minutes before calling
again.
5. Keep messages short and brief. Know what
you are going to say before you depress the micro-
phone button. Many 100 word discussions can be
reduced to 10 word messages by thinking and
planning before going ~on-the-air.”
6. Adopt a system of routine and preventative
maintenance with your serviceman.
7. Become familiar with the F.C.C. rules and
regulations concerning operation of two-way radio
for your particular class of service.
TRANSMITTER TUNE-UP PROCEDURE:
CAUTION
The plate cap of the type 6146 output
stage is “hot” at all times when power is
turned ON. This applies to both the
“STANDBY” and “ON” positions of the
power switch.
The transmitter duty cycle is one minute on, four
minutes off; therefore, all adjustments should be
made as quickly as possible. keying the transmitter
only when ready for actual adjustment or measure-
ment. To minimize interference, on-the-air testing
(with antenna connected) should be kept to a
minimum. The use of a 50 ohm dummy load is
recommended for all but the final on-the-air use
of the equipment.
If extended periods of testing and/or servicing
the exciter stages of the transmitter are required
it is recommended that the screen of the 6146 PA
stage be grounded. All tests up to and including
the grid of the final stage can be made.
TEST EQUIPMENT REQUIRED:
A. 0-100 micro-ammeter (2000 ohm internal re-
sistance) see schematic diagram for recom-
mended test meter circuit.
B. RF wattmeter with 52 ohm dummy load.
C. Modulation deviation meter.
D. Frequency meter with an accuracy of at least
+.001%.
1. With a 0-100 micro-ammeter connected from
terminal 3 of J105 to ground (terminal 11)
adjust L118 for maximum indication. (Position
3 of recommended test meter. !
2. With the micro-ammeter now connected from
terminal 4 of J105 to ground. adjust L116 and
L115 for maximum indication. (Position 4 of
recommended test meter.)
3. With the micro-ammeter now connected across
terminals 5 and 7 of J105. adjust C159 for
maximum indication. The value of shunt R153
is such that a microammeter with an internal
resistance of 2000 ohms will actually read 10
milliamperes at full scale. When making this
adjustment, a minimum of 2.5 milliamperes
should be obtained. (Position 5 of recommended
test meter.)
4. With the micro-ammeter connected across ter-
minals 9 and 10 of J105 (position 6 of recom-
mended test meter), C153 set at maximum capa-
city (minimum loading CCW). C154 should be
adjusted for minimum plate current. The value
of meter shunt R149 is such that the micro-
ammeter will read 200 milliamperes full scale.
With the dummy load connected to the output
terminal, C153 should be slowly reduced in
capacity watching the plate current rise. This
loading should be increased until a plate current
reading not exceeding 160 milliamperes is
achieved. Simultaneous with this loading adjust-
ment the PA plate tuning condenser C154
should be continually readjusted for minimum
plate current so that the final value of 160
milliamperes is achieved with this adjustment
always set for the lowest possible plate current.
Excessive loading as indicated by abnormally
high plate current may be cured by the use of
additional capacity in parallel with the antenna
loading capacity, C153, or changing taps on
L112. This is normally taken care of at the
factory when the transmitter is tuned to the
customer’s frequency.
5. After making the above adjustments, the trans-
mitter frequency should be set against a known
standard. This adjustment is C183 associated
with the crystal oscillator stage V113A.
6. After making the previous adjustments the
deviation should be adjusted by applying a
1000 cycle tone of 1.0V rms amplitude to the
microphone connector J104. Potentiometer R172
should be adjusted for +5 Ke deviation as indi-
cated on a deviation meter. This adjustment
should always follow step 5 above.
Note: Since this transmitter covers a frequency
range of greater than 2 to 1, it is possible to tune
one or more stages to the incorrect harmonic and
still get drive and output. When making large
changes in operating frequency or if it is not
possible to get proper drive at any stage, check
for proper multiplier adjustment with an absorp-
tion wave meter or grid dip meter.

COMPLETE RECEIVER ALIGNMENT PROCEDURE
TEST EQUIPMENT REQUIRED:
A. 0-100 micro-ammeter (2000 ohms internal re-
sistance).
B. DB Audio output meter.
C. Low frequency signal generator covering 1650
KC, 10.7 MC and 10.7075 MC.
D. High frequency FM signal generator covering
25 to 54 MCS.
1.(a) Connect a 1650 KC signal to pin 9 of VIO4A.
(b) Connect micro-ammeter from J105 pia 3 to
ground. (Position 3 of recommen:'d test
meter. )
(c) Adjust top and bottom of T104 for maximum
indication.
2.(a) Connect micro-ammeter from J105 pin 2 to
ground. (Position 2 of recommended test
meter. )
(b) Adjust top and bottom of T102 and T103
for maximum indication.
(c) As each adjustment is brought into reso-
nance, the output of the signal generator
should be decreased so as to produce a meter
reading between 25 and 75 microamperes.
This precaution is necessary so as to elimi-
nate the possibility or overload which will
result in false peak indications.
3.(a) Connect a 10.7 MC signal to pin 1 of V102A.
(b) Leave micro-ammeter connected to pin 2 of
J105. (Position 2 of recommended test
meter. )
(c) Adjust L106, L107 and L108 for maximum
indication observing step 2(c) above.
4.(a) Connect a 10.7075 MC signal to pin 1 of
: V102A.
(b) Leave micro-ammeter connected to pin 2 of
J105. (Position 2 of recommended test
meter. )
(c)
8.(a)
(c)
Readjust L106 and L107 for maximum indi-
cation observing step 2(c) above. Do not re-
align adjustment L107.
Connect micro-ammeter from pin 1 of J105
to ground. (Position 1 of recommended test
meter.)
Adjust L103 (oscillator) for maximum indi-
cation.
Connect signal generator on signal frequency
to antenna terminal, J102.
Connect micro-ammeter from J102 pin 2 to
ground. (Position 2 of recommended test
meter. )
Adjust T101, ZF101 for maximum indication
observing precaution outlined in step 2(c).
With an input signal of approximately .5
microvolt, touch up T101, ZF101 and L108
for maximum quieting. This will approxi-
mate the same resonance points as maximum
lst limiter grid current indication.
Adjust L109 for maximum hiss level keeping
the front panel volume control below the
overload point.
With an on-channel frequency modulated
signal applied to the input of the receiver,
readjust L109 for maximum recovered audio.
Some interaction between T104 and L109 is
normal. The recommended procedure is to
de-tune L109 off the peak of maximum out-
put, adjust T104 for maximum grid current
as indicated at position 3 of the recom-
mended test meter and then adjust L109 in
accordance with step (b) above. Do not
touch the adjustments of T104 after L109
has been adjusted.
9.(a) Loosely couple an accurate 10.7 MC signal
to the grid of V102A (Pin 1) and adjust
L103 for an aural zero beat indication in the
loud speaker with an on frequency signal
applied to the antenna input terminal J102.
(b) With the same unmodulated input signal
follow step 7(a).
(c) Adjust the FM detector coil L109 as outlined
in steps 8(a) and 8(b). In lieu of this tech-
nique the modulation of an “on-frequency”
base station or mobile transmitter may be
used. In this instance L109 should be ad-
justed for maximum audio consistency with
lowest distortion.
It is highly recommended that the service tech-
nician make a few practice runs on a normal operat-
ing unit. With a little practice the alignment may
be accomplished in less time than that required to
read the procedure outlined above.
RECEIVER ALIGNMENT PROCEDURE, FIELD SERVICE
The “Complete Receiver Alignment Procedure”
will rarely be required in the field however it
should be reviewed in order to become thoroughly
familiar with the receiver section of the unit. Re-
ceiver field alignment should be accomplished as
follows.
10.(a) With an input signal (unmodulated) strong
enough to produce approximately 20 db
quieting of the thermal noise (hiss) adjust
L103 to zero the first oscillator with the
incoming signal as outlined in step 9(a).
NoTE: Frequency netting of the receiver is ex-
tremely important particularly when ignition
noise is present. Follow the previous instructions
carefully for best performance.
10.(b) Perform step 7(a) above.
CABLE INSTALLATION
Certain precautions must be observed when in-
stalling the FM 60A. It is very important that
polarity be observed on vehicle installations. Using
the power cable chart. at the rear of the manual,
first, determine which cable is to be used. In most
installations, you will find that modern vehicles
employ a 12 volt negative ground system, therefore,
be sure to use the cable required for 12 volt nega-
tive ground installations. If the vehicle is a positive
ground system be sure to use the 12 volt positive
ground cable, etc. Refer to rear of manual for cable
connections for front mount installations.
New vehicles will generally be no problem so far
as polarity is concerned. On older vehicles, the best
policy is to use a volt meter and check the battery
voltage and polarity before proceeding with the
installation. Experience will generally tell you
what the voltage and polarity of the various make
and type vehicles in the field are.
It is extremely important that polarity and volt-
age be observed because if the polarity is acciden-
tally reversed, you will, almost without exception.
burn out at least one of the power transistors. TO
PREVENT BURNING OUT POWER TRANSIS-
TORS, OBSERVE VOLTAGE AND POLARITY.
Once the proper cable has been installed in a
vehicle, the FM 60A receiver-transmitter unit may
be exchanged or inter-changed throughout the fleet
with no modification or switch selection required.
COMMUNICATIONS UNIT INSTALLATION
There are generally three or four different ways
that the unit may be mounted in the cab or in the
area that is accessible to the driver. In most busi-
ness and industrial applications, it will be found
that it is most desirable to locate the receiver-
transmitter somewhere in the cab of the truck or
the front seat area of the vehicle. This has the
advantage of short battery cables with less voltage
drop and less chance of abrasion and wear.
FLOOR MOUNT:
Using the FM 60A receiver-transmitter as a pat-
tern, place it on the floor of the vehicle and various
locations until the most convenient location ‘is
found. The best location will be one where the
driver can tel] at a glance whether his set is on
or off and where he can reach the controls on the
front panel. When setting up this location, be sure
to give consideration to the length of the battery
cable. After the location is found, secure the uni-
versal mounting bracket, Hammarlund Part No.
PL26610-Gl. When drilling through the floor of a
vehicle, or through any other panel or part of it,
use every precaution to avoid drilling through a
gas line or electrical] wiring, etc. Wherever it is not
possible to use nuts and bolts, drill with a proper
size drill for self tapping screws and, using a good
long screw driver, drive the steel screws firmly
into place. Always fasten parts securely to the
vehicle to avoid noise from “shaky” installation.
UNDER-DASH MOUNT:
Using the radio as a template. find the best loca-
tion under the dash of the vehicle. Take into con-
sideration, special handles found on dump trucks
and controls found on various types of vehicles in
the field. After a practical location is found, secure
the universal mounting bracket in place with the
proper hardware. Use every precaution to make the
battery cable as'short as possible and route it in
such a way that it will not interfere with the various
controls under the dash. Wherever the cable goes
through the chassis. use a heavy rubber grommet
to prevent chafing and eventual short circuit. Extra
precautions seldom take more time when the in-
stallation is being made, but can save many hours
of future maintenance and possibly a dangerous
situation for the driver.
REMOTE INSTALLATIONS:
Whenever it is not practical or desirable to have
the radio unit mounted in view of the driver, it
should be mounted remotely. In a passenger car
the most practical place is usually in the trunk;
however. there are certain vehicles that adapt them-
selves to other locations. Always. bear in mind that
the hattery cable should be as short as possible and
use the same precautions discussed for the floor
mount. Place the unit in such a way that it will not
interfere with loading and unloading of the trunk
and find the shortest route from the unit to the
battery. running the cable along this route. Avoid
sharp metal, protrusions, and use every means to
protect the cable from abrasion. Whenever it is
necessary to run the battery cable on the outside of
the vehicle under the floor, stay clear of areas that
get extremely hot, such as the exhaust pipe or the
muffler. The cable connecting the unit to the remote
head, should be run on the inside of the vehicle
unless it is possible to employ metal flexible tubing.
Type CU-11A mobile remote contro] unit has
been designed specifically for this purpose. This
remote contro] unit consists of an “on-standby-off”
power switch, a volume control. a squelch control.
a built-in speaker and indicator lights. The CU-l1A
is shipped with installation instructions including
the wiring connections of the rear mount cables.
These cables differ from the front mount cable
somewhat because the power switch on the front
panel of the FM 60A is inoperative in a rear mount
installation. This provides for complete power con-
trol of the unit from the dash of the vehicle includ-
ing the battery saving switch feature. Refer to the
complement chart of this instruction manual for
other rear mount items, such as contro] and power
cables, etc.
BATTERY CABLE INSTALLATION:
The battery cable should be run from the unit
to the battery in as short a line as possible. Some-
where near the battery. mount the fuse holder and
fuse with the two sheet metal screws furnished.
Terminate the “hot” lead at the fuse holder. cutting
off any extra cable. Using this extra cable. run a
lead from the other side of the fuse holder to the
“hot” side of the battery. Terminate this “hot” lead
at the battery terminal, or on the starter post. Never
connect to a voltage point on the vehicle that has
wire smaller than the starter cable. Do not substi-
tute a wire that is of smaller diameter than that
furnished with the installation kit.
The ground lead in the trunk mount installations
should be securely bonded in the immediate vicinity
of the unit. Do not ground to upper braces and /or
trunk lid mounting bolts. It is preferable to attach
the ground lead to the floor of the trunk and solder
same if at all possible. This will require an un-
usually large iron (500 watts preferably) and a
good mechanical, as well as electrical connection
is a must. In front mount installations the ground
lead (black) should be securely fastened to the
battery terminal or to the engine block.
ANTENNA INSTALLATION:
General installation instructions are furnished
with the various antenna kits. However, there are
certain precautions that must be observed when
installing any antenna.
The most frequently used antenna will be the
quarter wave whip. Although the ideal location
for this antenna is the center of the roof of the
vehicle, rarely will it be possible to so locate it.
Avoid mounting the base of the antenna on the
bumper or in the vicinity of the rear bumper if at
all possible. The preferred location is in the area
of the trunk near the rear window. This is a happy
compromise between the area of the bumper and
the center of the roof.
If at all possible avoid mounting the antenna at
the front of the vehicle where ignition noise pick-
up may be excessive. In some cases the use of a
“disguised” type may be beneficial and same may
be had on special order. The “disguised” antenna
is supplied complete with cable harness and mount-
ing instructions.
Note: Before attempting to install the antenna in
the vehicle, it is a good idea to try all pieces for
fit to make sure that possible burrs or foreign
matter might cause mating pieces to bind during
final assembly.
ROUTING OF ANTENNA
TRANSMISSION LINE:
Always route the transmission line through the
area which provides maximum clearance. AVOID
SHARP BENDS. As the cable may go under up-
holstery, metal fittings, etc.. be sure to place it in
such a way that it will not be squeezed when the
fittings, frames, etc., are put back in place. After
replacing all trim and metal work, the co-axial
cable and roof top antenna should be checked for
continuity between the center conductor and the
whip. The co-axial cable should next be checked
for lack of continuity between its inner and outer
conductors.
ATTACHING CO-AXIAL CABLE
CONNECTOR:
1. Cut cable off square at the proper length.
2. Cut off 1144” of outside plastic insulation
jacket.
3. Comb out copper shield.
4. Cut inner insulation off to expose 52” of
inner conductor.

5. Trim stranded shielding so it is about 146
shorter than the inner insulation. Slide
coupling through and adapter on cable.
folding the combed strands over the
adapter.
6. Tin center conductor and screw plug on
cable and adapter.
7. Solder shield strands through holes in
plug and solder center conductor of the
cable to the plug end.
Use enough heat to get a good solder joint. Avoid
using so much heat that the solder will flow from
the shell to the center conductor inside the plug.
Avoid handling the cable and plug until the soft-
ened insulation between the center conductor and
shield has had a chance to cool off and return to
its firm state.
8. Recheck for continuity.
The above instructions on attaching the co-axial
cable connector may be ignored when antenna cable
assemblies are ordered complete with connectors,
as same are already attached. Refer to the comple-
ment chart of this manual for further information.
Note: The antenna should be cut to its proper
operating frequency. The preferred method is to
use a test whip which may be adjusted for mini-
mum standing wave ratio and the final adjust-
ment length used as a cutting guide for the whip.
The standard 8 ft. whip (prunable) will require
cutting to exact length depending upon the
operating frequency of the unit and/or the physi-
cal configuration of the vehicle to which it is
attached. Low band test whip Hammarlund part
number 53164-1 is highly recommended. If this
is not available the whip may be cut in accord-
ance with the following chart:

After the installation is complete, insert a “thru-
line” RF watt meter between the FM 60A antenna
output connector and the PL259 plug of the an-
tenna transmission line. Tune the output stage of
the FM 60A in accordance with previous instruc-
tions supplied in this manual. Check the reflected
power which should normally not exceed 10%. Un-
usually high reflected power may he caused by one
or more of the following reasons:
1. Incorrect whip length.
2. Damaged transmission line.
Break in outer shield of transmission line.
pw
. Antenna mounted in close proximity to other
objects on the vehicle.
In the latter instance (4) modifying the whip
length from the “free space” dimension may
correct the condition.
FREQUENCY ADJUSTMENT:
The Federal Communications Commission re-
quires that all transmitters of this type be checked
for frequency upon installation and at least once
every twelve months thereafter with an instrument
having an accuracy of twice that of the equipment
being measured. In this instance the measuring in-
strument should be rated at +.001%.
All transmitters are adjusted to frequency prior
to shipment, however, the installer is required by
the FCC to make this test upon completion of the
installation.
