Re: [Elecraft] K3 P3 Spurious signals

2013-02-19 Thread 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

Fred and I discussed this problem off line a couple of weeks ago as I have the same thing here. I did wiggle and re-seat my BNC cable but did not try another one. I will try that first thing in the morning when I get home as I found wiggling the cable did alter it a bit. Thanks Ian, Dave
