[Lowfer] 600MRG> WE2XGR/2 in WOLF mode 506.5 kHz ... USB

While WOLF (and some other modes) will decode in either sideband (if proper calibration is 
maintained) other digital modes that have a 'polarity' will require the 'REV' setting ... to be 
consistent with the transmitting end (USB by convention). My R-75 is cal'ed for 'REV' only ... since 
that provides USB CW reception and works with all modes.
