Hi Bob, I have a spare XG1 I can send you if you want to do gain calibration, but don't have any other means of getting an S9 and S1 signal source.
This is almost certainly a simple calibration issue. You should start by running K3 Utility's "RF GAIN Cal" routine, selecting factory defaults, which doesn't require a signal generator. You can follow this with tweaking of CONFIG:SMTR OF and SMTR SC until a no-signal condition gives you no bars. 73, Wayne N6KR On Oct 13, 2009, at 10:11 AM, Bob Harvey - K2PI wrote: > > Hi: I've been noticing s2-s3 receiver noise on my K3 (SN:2195) with > the > antenna's disconnected.
