Hint!
Voice patterns and audio characteristics vary with
each operator, therefore the [MIC GAIN], DSP TX
Audio Pass Band and Microphone Tone Control
settings will be different for each operator. Actual on
air experimenting is necessary to get just the right
sound. Listen to your transmit audio with head-
phones and the monitor function turned ON. It's
also best to test and adjust your audio on the air,
while someone who knows what your real voice
sounds like listens, and provides and opinion on
your audio quality.
