40 channel CB Transceiver
Professional Quality And Performance Standards
Advanced Circuitry With PLL Synthesis

GENERAL INSTRUCTIONS
Your model is an all solid-state SSB/AM transceiver for 27MHz Citizens' Band
use. It uses a frequency synthesized circuit to provide Phase Locked Loop
controlled transmit and receive operation on all 40 channels. You can use
your transceiver on any one of the 40 channels in the conventional AM mode,
plus the same 40 channels in either the Upper Single Sideband or Lower Single
Sideband mode. The flexibility of SSB mode not only doubles the effective
number of channels from 40 to 80, but also increases the effective range of
communication because all the power is concentrated in one sideband to provide
100 percent talk-power. Single Sideband reception also adds advantages in
sensitivity and selectivity, plus lower signal-to-noise. This of course also
contributes to increase in operating range.
Your model is carefully designed for ease of operation. You can select the
SSB mode of the Upper Sideband or Lower Sideband, and/or AM with simple switch
of the button. Transmission is simple, too - just press the microphone button.
Ordinarily SSB signals reach farther and are heard more clearly than equivalent
AM signals. SSB reception on the selected sideband is simple, too - you just
adjust the Clarifier control for fine tuning of the received voice.
We add all the other wanted features for optimum communication - RF Gain
Control, Squelch Control, Noise Blanker, full-time Automatic Noise Limiter to
combat ignition noise and S-RF-PA level meter.
This transceiver is designed to operate from a normal 12 volt DC supply (positive
or negative ground system).

Fig. 1
MOBILE INSTALLATIONS
A location in the Car or Truck should carefully be chosen for convenience of opera-
tion and non-interference with normal driving functions. Mounting may be under the
dash or the instrument panel or any place where a secure installation.can be made.
DC POWER CONNECTION
This transceiver may be operated from a 12 volt DC battery source on Negative or
Positive ground system. It is designed to operate within an input voltage range
of 11.6 to 15.6 volts DC. Make sure that the voltage to the transceiver does not
exceed 15.6 volts DC.
NOTE:
Before making any power connection, you must determine whether the vehicle or boat
has a negative or positive electrical ground system. Then make the following
connections.
1.
Using the end of the DC power cable, connect the fused Red lead to the "+"
(positive) side of the electrical system and the Black lead to the "-" (negative)
side of the electrical system. In case of the negative ground system, the Red
lead should be connected to the accessory post on the ignition switch, the
voltage regulator side of the ammeter and/or the accessory side of the fuse block.
The Black lead should be connected to the metal firewall or any other point that
is connected to the vehicle chassis(ground).
2.
In case of the positive ground system, the Black lead should be connected to
the accessory post on the ignition switch, the voltage regulator side of
ammeter and/or the accessory side of the fuse block. The Red lead should be
connected to the metal firewall or any other point that is connected to the
vehicle chassis(ground).
TRANSCEIVER MOUNTING
Before installing the transceiver in a car, truck and etc., be sure to choose a
location which is convenient to the operating controls and will not interfere with
the normal functions of the driver. The transceiver may be mounted to the under-
side of the instrument panel or„dashboard of a car, truck and etc., by means of
the special brackets which are supplied with the transceiver. Attach the brackets
to the underside of the instrument panel using self-threading screws (See Fig. 1).

Secure the transceiver to the brackets by means of the large knurled thumbscrews.
Tilt the transceiver to a position which provides the operator with the best view
of the front panel, then tighten knurled thumbscrews securely.
ANTENNA CONNECTION
The antenna lead-in cable (RC-58U or RC8/U) should be terminated with a PL-259 type
coaxial conne·ctor which should then be attached to the matching S0-239 connector
at the rear of the transceiver.
MICROPHOl~E ( ONNECTICJN
Insert the 4-pin plug at the end of the coiled cord into the microphone socket.
MOBILE ANTlNNI\
The antenna system is included the transmission line and it is very important that
you use the correct type of the transmission line. The transmission line should
be the coaxial type and should have an impedance equal to the antenna impedance
which must
be 50 ohms. Generally speaking, you should keep the length of the
transmission line minimum. Remember that line losses increase with frequency.
To use a foam-insulated coax for best results. The above discussion is as
important for reception as it is for transmission. If a mismatch exists between
the antenna and the transceiver, the excellent sensitivity and signal-to-noise
ratio of the receiver circuitry will be defeated.
The most popular fixed station antenna is a 5/8 wave type for omnidirectional opera-
tion and various beam antennas for directional operation. The directivity can be a
disadvantage unless a rotar is used. Since a beam antenna is directional, it
generally reduces noise and interference from all other directions. This can be
a decided advantage on the CB bands where man-made noise is a problem. The antenna
system should be adequately grounded and extreme care should be exercised to prevent
it from contacting with a power line during installation.
'1,NITIOr'J INTLRFRlNCE
Your transceiver is equipped with a special RF Noise Silencer which is designed
to provide outstanding reduction of ignition noise. Ignition interference should
not therefore be a problem in most cases. However, sufficient noise may be
generated by some vehicles to make it necessary to install additional suppression.
Several noise suppressor kits are available which include all necessary parts and
instructions. Take your vehicle to a skilled auto radio technician who will be
able to carry out the suppression for you.
USING YOUR TRANSCEIVER
Do not transmit without a suitable antenna or load to the antenna connector.
For installation, refe~ to that section.
1. Set the RF Gain Control (6) maximum clockwise.
2. Set the Squelch Control(8) maximum counter-clockwise.
3. Set the Mode Switch(l2) to AM.
4. Push the Power Switd1(S) 01~.
5. Set the Channel Selector(ll) to the desired channel.
6. Adjust the Squelch Control(8) to cut out annoying background noise when,-00
signal is being received. To do this, set the Channel Selector(ll) to a
channel where no signals are present (or wait until signals cease on your
channel). Then rotate the Squelch Control(8) in a clockwise direction to
the point where the background noise just stops. Now, if a signal is present,
you will hear it without being disturbed by noise on the channel in between
signals. When properly set, the Squelch will keep the receiver "dead" until
a signal is coming in on that channel. Do not set the Squelch too high or
weak signs.ls. Th~s will not be able to "open" the Squelch circuit. To
receive weak signals, it is best to leave the Squelch setting to the minimum
position (maximum counter-clockwise).
7. Use the Clarifier(?) to tune in slightly off-frequency stations.
8. Adjust the Volume Control(5) for suitable listening level.
1. Set the RF Gain Control(6) maximum clockwise.
2. Set the Squelch Control(8) maximum counter-clockwise.
3. Set the Mode Switch(lZ) to either LSB or USB, depending on which sideband
is being used by the transmitting station.
4. Push the Power Switch(5) ON.
5. Set the Channel Selector(ll) to the desired channel.
6. Adjust the Squelch Control(8) as noted above.
7. Use the Clarifier(?) to tune in the SSB signal. The SSB tuning takes
practice, it is not difficult, it just takes a little experience. When
first listening to an SSB signal, it will probably not be understandable.
The noise may sound like "Donald Duck" or just a low guttural sound, In
either case, adjust the Clarifier(?) very slowly to bring the signal into its
natural voice level range. If the signal is "Donald Duck" like, tune the
Clarifier(?) to lower tones. If the signal is low and guttural, tune the
Clarifier(?) to higher tones. Careful tuning will make the noise sound
natural. If you try above procedure and are not able to make the signal
intelligible, it may be operated on the other sideband. Try the other
SSB mode (LSB or USB as the case may be).
8. Adjust the Volume Control(5) for suitable listening level.
NOTES ON RlCE'VIN'~
An SSB signal produces a fluttering and unintelligible sound when receiving in the
AM mode. In such a case, use either the LSB or USB mode and adjust the Clarifier
for intelligility. You can tune AM signals when the Mode Switch is in the LSB or
USB position, tune the Clarifier to eliminate the steady tone cased by the AM
carrier ("zero-beat" the tone so it disappears). When receiving an extremely strong
signal, you will find it best to use the RF Gain Control to vary the volume (rather
than using the Volume Control).
(,ENERAL TRM~SMIT TIN1 INSTRUCTIONS
Make sure that the proper connections have been made on the power cable, antenna
system and microphone, and the correct cable has been used. Be sure that the
transceiver is properly grounded (if not mounted directly to a metal surface).
To transmit, (after all controls are preset for receive), ~old and press the micro-
phone "push~to-talk switch". Hold the microphone about 5-10 ·centimeters from your
mouth and speak in a normal tone of voice. Release the "push-to-talk switch" to
receive.
