[Elecraft] K3 P3 Spurious signals

[Dave Van Wallaghen]

Tried another BNC cable I had here and it knocked the problem down 
appreciably. Without an antenna connected (well, a 6' piece of RG8) I 
can barely see them on 40m - they are non existent now on 10m. With my 
antenna connected, I can't see them at all anymore - well below the 
noise level I have here.

The cable I tried has connectors that fit much tighter (no wiggling at 
all) than the Elecraft supplied cable. So I'm not sure if it is the 
connectors or a bad crimp as others have suggested.

I may tear my P3 down at some point to look at the case grounding and 
clean them up. This may help even further if there is a grounding problem.

73,
