K3 Rf gain tracking (main vs. sub)

[Vic K2VCO]

There are two 'gain calibration' procedures. One is for TRANSMIT gain which requires a
dummy load. The other is for receiver RF gain and it can be done with a signal source or
by loading the factory defaults without a signal source.

It is on the Calibration page of the K3 Utility and is a button labeled 'Calibrate RF Gain'.
