Drive gain adjustment
The drive gain is active for all modes other than SSB
mode with speech compressor OFF. The [DRIVE] con-
trol adjusts the amplifying gain at the driver stage.
Before transmitting, monitor your selected operating
frequency to make sure transmitting won’t cause inter-
ference to other stations on the same frequency.
