C. Check your coaxial cable routing (it may be pinched when routed
into the car).
D. Try a different location on 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 or light posts,
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.SPK) 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.

Operation

CONTROL FUNCTIONS

There are thirteen controls and three indicators on the front panel of
your transceiver.

FRONT PANEL

1. OFF/ON/VOLUME (inner dual concentric). Turn clockwise to apply
power to the unit and to set the desired listening level. During normal
operation, the VOLUME control is used to adjust the output level
obtained either at the transceiver speaker or the external speaker, if used.
2. SQUELCH (outer dual concentric). This control is used to cut off or
eliminate receiver background noise in the absence of an incoming
signal. For maximum receiver sensitivity it is desired that the control be
adjusted only to the point where the receiver background noise or
ambient backgrounds noise is eliminated. Turn fully counterclockwise
then slowly clockwise until the receiver noise disappears. Any signal to
be received must now be slightly stronger than the average received
noise. Further clockwise rotation will increase the threshold level, which
a signal must overcome in order to be heard. Only strong signals will be
heard at a maximum clockwise setting.
3. MIC GAIN (inner dual concentric). Adjust the microphone gain in the
transmit and PA modes. This controls the gain to the extent that full talk
power is available several inches away from the microphone.
4. RF GAIN CONTROL (outer dual concentric). Use to reduce the gain
of the RF amplifier under strong signal conditions.
