Adjusts 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. In the Public Address (PA) mode, the 
control functions as the volume control. 
 
4. RF GAIN CONTROL 
This control is used to reduce the gain of the RF amplifier under strong signal conditions. 
 
5. MODE SWITCH 
This control allows you to select one of the following operating modes: PA/FM/AM. 
 
In the PA position, the radio...

17. S-RF/SWR SWITCH 
This is a two-function switch. In the S-RF position, the meter will indicate the strength of the signal 
being received, as well as the relative RF output of transmission. To use the meter to measure the 
standing wave ratio, turn the switch to the SWR position. The SWR function is self-calibrating. 
 
18. NB/ANL/OFF SWITCH 
In the NB/ANL position, the RF Noise Blanker and the Automatic Noise Limiter in the audio circuits 
are also activated. The Noise Blanker is very...
