[R-390] A Little Help Needed

[Cecil Acuff]

Also a pretty good test would be to check for the calibrator signal on each 
band and note it's signal level reading after peaking the signal with the 
antenna trimmer control...turn the BFO on while doing this...makes it a bit 
easier.

Should be a difference between MGC and AGC in most all cases.
