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.

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,

Fred, Peter: have you replaced the Elecraft supplied BNC-BNC cable?
I had very similar problems because the cable shield was improperly
crimped at both ends. A BNC cable from the junk box cured the problem
almost completely.
