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
K3 [#642] w/P3 in FixTune mode [cursor moves, ends of screen are fixed].
K3 has the resistor mod to increase the 8 MHz IF output. I see them
on CW, I haven't tried SSB.
I've got a pair of weak, steady spurious signals ~14.5 KHz above and
below the VFO A cursor. They tune with the VFO [i.e.

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
