MOD POWER OFFSET
0.0 dB
Modulator power offset adjust. Offsets the
modulator output power readout in the
Configuration menu. This feature does not
actually change the modulator power level,
but displays an offset value in the monitor.
The modulator power offset range is -99.9 to
+99.9 dB, in 0.1 dB steps.
Note: Anything except 0.0 dB will cause ADJ
to be displayed for the TX power level
