PROCEDURE TO RECEIVE AND TRANSMIT 

 

A. MICROPHONE 

 
The receiver and transmitter are controlled by the push-to-talk switch on the 
microphone. Press the switch and the transmitter is activated, release switch 
to receive. When transmitting, hold the microphone two inches from the 
mouth and speak clearly in a normal voice. This transceiver comes complete 
with a low impedance dynamic microphone.  
 

B. PROCEDURE TO RECEIVE 

 
1. Be sure that power source, microphone and antenna are connected to the 

proper connectors before going to the next step. 

 
2. Press the 

POWER

 switch to apply power to the radio. 

 
3. Set the 

VOL

 for a comfortable listening level. 

 
4. Set the 

MODE

 switch to the desired mode.   

 
5. Listen to the background noise from the speaker. Turn the 

SQ

 knob slowly 

clockwise until the noise just disappears. The 

SQ

 is now properly 

adjusted. The receiver will remain quiet until a signal is actually received. 
Do not advance the control too far or some of weaker signals will not be 
heard. 

 
6. Set the 

CHANNEL

 selector switch to the desired channel. 

 
7. Set the 

RF GAIN

 control fully clockwise for maximum RF gain. 

 

C. RF POWER CONTROL 

This feature allows for the adjustment of the RF power output continuously 
over the range of 1 to 4 watts in AM and 4 to 12 watts in USB or LSB. 
 

D. PROCEDURE TO TRANSMIT 

 
1. Select the desired channel of transmission 
 
2. Set the 

MIC GAIN

 control fully clockwise. 

 
3. If the channel is clear, depress the push-to-talk switch on the microphone 

and speak in a normal voice.
