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.).
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 fifteen controls and four 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 CONTROL (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. ECHO (inner dual concentric): This control is used to echo effect.
4. TONE (outer dual concentric): This control is used to intervals of echo
sound.
