✔ What is the AGC?

The AGC controls the receiver gain to produce a con-

strength varies dramatically. Select “FAST” for tuning and

then select “MID” or “SLOW,” depending on the receiving

condition.

The speech compressor compresses the transmitter

audio input to increase the average audio output level,

to increase talk power. This function is effective for long-
