The RF speech compressor increases the average RF
output power, improving signal strength and readability
in SSB and AM modes.
Push [SSB] or [AM/FM] to select SSB or AM mode.
While menu set 1 is selected, push [F3](
turn the speech compressor ON.
• "COMP" appears when the function is ON.
Set the [MIC GAIN] to the 9 to 12 o'clock position.
While speaking into the microphone, adjust [MIC
GAIN] so that the ALC meter reads within the ALC
zone whether you speak softly or loudly.
Use the monitor function (see previous page) to
check that any distortion to your transmitted audio
is at a minimum.
