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.). 

 
 
 
 
 

 
 

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 eighteen 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 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.  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. 

 
 
 
 
 

- 8 - 

 

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.
