Convenient functions for transmit
q
Speech compressor (p. 46)
The speech compressor compresses the transmitter
audio input to increase the average audio output level.
Therefore, talk power is increased. This function is ef-
fective for long distance communication or when prop-
agation conditions are poor.
w
VOX (voice activated transmit) (p. 43)
The VOX function starts transmission without pushing
the transmit switch or PTT switch when you speak into
the microphone; then, automatically returns to receive
when you stop speaking.
e
Transmit quality monitor (p. 45)
This function allows you to monitor the quality of your
transmitted signal.
