INSTALLATION
A
LOCATION
Plan the location of the transceiver and microphone bracket before starting the installation.
Select a location that is convenient for operation and does not interfere with the drive or
passengers in the automobiles, the transceiver is usually mounted the dash panel with the
microphone bracket beside it.
MOUNTING THE RADIO
The transceiver is supplied with a universal mounting bracket. When mounting the bracket and
radio to your car, make sure it is mechanically strong. Also provide a good electrical connection
to the chassis of the vehicle. Proceed as follows to mount the transceiver:
1. After you have determined the most convenient location in your vehicle, hold the
transceiver with mounting bracket in the exact location desired. If nothing will interfere with
mounting it in the desired position remove the mounting bolts. Before drilling the holes,
make sure nothing will interfere with the installation of the mounting bolts.
2. Connect the antenna cable plug to the standard receptacle on the rear panel. Most
transceiver antennas are terminated with a type PL-259 plug and mate with the receptacle.
3. Connect the red DC power input wire (with the fuse) to +13.8V DC. This wire extends from
the rear panel. In automobile installation, +13.8V DC is usually obtained from the
accessory contact on the ignition switch. This prevent the set being left on accidentally
when the driver leaves the car and also permits operating the unit without the engine
running. Locate the accessory contact on most ignition switches by tracing the power wire
from the AM broadcast receiver in the car.
4. Connect the black lead to –13.8V DC. This is usually the chassis of the car. Any convenient
location with good electrical contact (remove paint) may be used.
5. Mount the microphone bracket on the right side of the transceiver, using two screws
supplied. When mounting in an automobile, place the bracket under the dash so that
microphone is readily accessible.

INSTALLATION
A
IGNITION NOISE INTERFERENCE
Use of a mobile receiver at low signal levels is normally limited by the presence of electrical
noise. The primary source of noise in automobile installation is from the generator and ignition
system in the vehicle. Under most operating conditions, when signal level is adequate, the
background noise does not present a serious problem. Also, when extremely low level signals
are being received, the transceiver may be operated with vehicles engine turned off. The unit
requires very little current and therefore will not significantly discharge the vehicle battery.
Even though the transceiver has ANL and NB controls, in some installation ignition
interference may be high enough to make good communications impossible. The electrical
noise may come from several sources. Many possibilities exist, as variations between vehicles
require different solutions to reduce the noise.
ANTENNA
A vertically polarized, quarter-wavelength whip antenna provides the most reliable operation
and greatest range. Shorter, loaded-type whip antennas are more attractive, compact and
adequate for applications where the maximum possible distance is not required. Also, loaded
whips do not present the problems of high wind resistant imposed by a full quarter-wavelength
whip.
Mobile whip antennas utilize the metal body of the vehicle as a ground plane. When mounted
at a corner of the vehicle they are slightly directional, in the direction of the body of the vehicle.
For all practical purpose, however, the radiation pattern is nondirectional. The slight directional
characteristic will be observed only at extreme distances. A standard antenna connector (type
SO-239) is provided on the transceiver for easy connection to a standard PL-259 cable
termination.
If the transceiver is not mounted on a metal surface, it is necessary to run a separate ground
wire from the unit to good metal electrical ground in the vehicle. When installed in a boat, the
transceiver will not operate at maximum efficiency without a ground plate, unless the vessel has
a steel hull.
Before installing the transceiver in a boat, consult your dealer for information regarding an
adequate grounding system and prevention of electrolysis between fittings in the hull and water.

INSTALLATION
A
TUNING THE ANTENNA FOR OPTIMUM S.W.R
Since there is such a wide variety of a base and mobile antenna, this section will strictly
concern itself to the various types of mobile adjustable antennas.
Because the antenna length is directly related to the channel frequency, it must be tuned to
resonate optimally on all channels of the transceiver. Channel 1 requires a longer antenna than
Channel 40 because it is lower in its frequency of operation.
Due to the various methods of adjusting antennas for proper S.W.R. we have chosen what
we think is the optimum method:
A. Antenna with adjustment screws (set screws).
1. Starts with the antenna extended and tighten the set screw lightly enough so that the
antenna can be lightly tapped with your finger for easy adjustment.
2. Set your transceiver to Channel 20. Press the PTT (push-to-talk) switch, and tap the
antenna (making it shorter). The S.W.R meter will show a lower reading each time the
antenna is tapped. By continuing to shorten the antenna, you will notice the S.W.R reading
will reach a low point and then start rising again. This means that you have passed the
optimum point for Channel 20.
Extend the antenna a short distance and again follow the procedure above. When the lowest
point has been reached, switch to Channel 1 and then to Channel 40 and compare S.W.R
readings. They should be almost equal.
NOTE
The proper setting is achieved when the SWR is 1.5 or
below, and when it has the same reading for channels 1
and 40.
B. Antennas which must be cut to proper length
1. Follow the same procedure as above but adjust the length by cutting in 1/8” increments
until a good match is obtained.
2. Be very careful not to cut too much at one time, as one it is cut, it can no longer be
lengthen.
3. The whip is easily cut by filing a notch all the way around and breaking the piece off with
pliers.

INSTALLATION
A
If you’re having difficulties in adjusting your antenna, check the following:
a. All doors must be closed when adjusting the antenna
b. Make sure the antenna base is grounded.
c. Check your coaxial cable routing (it may be pinched when routed into the car)
d. Try a different location in your car (keeping in mind the radiation pattern you wish.)
e. Is the antenna perfectly vertical?
f. Try a different location in your neighborhood. Stay away from large metal objects when
adjusting (metal telephone polls or light post, fences, etc.)
NOTE
The transceiver will operate into an SWR of 2 to 1
indefinitely and sustain an SWR of 20 : 1 for a maximum of
5 minutes at rated operating conditions.
EXTERNAL SPEAKER
The external speaker jack (EXT SP.) on the rear panel is used for remote receiver monitoring.
The external speaker should have 8 ohms impedance and be able to handle at least 4 watts.
When the external speaker is plugged in, the internal speaker is disconnected.

ALTERNATE MICROPHONES AND INSTALLATION
For best results, the user should select a Condenser type microphone. The microphones
must be provided with a four-lead cable. The audio conductor and its shielded lead
Comprise two of the leads. The third lead is for transmit control and fourth is for receiving
Control
The microphone should provide the functions shown in schematic below.
4 WIRE MIC CABLE
Pin Number Mic Cable Lead
1 Audio Shield
2 Audio Lead
3 Transmit Control
4 Receive Control
Fig. 1 Transceiver Microphone Schematic Diagram
If the microphone to be used is provided with precut leads, they must be revised as follows.
1. Cut leads so that they extend 7/16" beyond the plastic insulating jacket of the microphone
cable.
2. All leads should be cut to the same length. Strip the ends of each wire 1/8" and tin the
exposed wire.
- 13 -
OPERATION
A
Before beginning the actual wiring, read carefully the circuit and wiring information provided
with the microphone you select. Use the minimum heat required in soldering the connections.
Keep the exposed wire lengths to a minimum to avoid shorting when the microphone plug is
reassembled.
Fig. 2 Microphone plug wiring
To wire the microphone cable to the plug provided, proceed as follows:
1. Remove the retaining screw.
2. Unscrew the housing from the pin receptacle body.
3. Loosen the two cable clamp retainer screws.
4. Feed the microphone cable through the housing, knurled ring as shown Figure 2.

OPERATION
A
5. The wires must now be soldered to the pins as indicated in the above wiring tables. If a vise
or clamping tool is available it should be used to hold the pin receptacle body during the
soldering operation, so that both hands are free to perform the soldering. If a vise or
clamping tool is not available, the pin receptacle body can be held in a stationary position
by inserting it into the microphone jack on the front panel. Before soldering the wire to the
pins, pre-tin the wire receptacle of each pin of the plug.
Fig. 3 Microphone plug pin numbers viewed from rear of pin receptacle.
6. Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the
microphone cable before starting to solder.
7. When all soldering connections to the pins of the microphone are completed, push the
knurled ring and the housing forward and screw the housing onto the threaded portion of
the pin receptacle body. Note the location of the screw clearance hole in the plug housing
with respect to the threaded hole in the pin receptacle body. When the housing is
completely threaded into the pin receptacle body, a final fraction of a turn either clockwise
or counterclockwise may be required to align the screw hole with the threaded hole in the
pin receptacle body. When these are aligned, the retaining screw is then screwed into place
to secure the housing to the pin receptacle body.
8. The two cable clamp retainer screws should now be tightened to secure the housing to the
microphone cord. If the cutting directions have been carefully followed, the cable clamp
should secure to the insulation jacket of the microphone cable.
9. Upon completion of the microphone plug wiring, connect and secure the microphone plug
in the transceiver.
