[Elecraft] P3 Hash

[Rowland R Johnson]

I'm not sure what you're asking but I'll give you an answer anyway. It 
may not have been entirely clear what Gene and I saw on our P3 that 
turned out to be a problem fixed by a different BNC cable. On my P3 the 
BNC connector problem caused signals to be presented on the P3 display 
that could not have been present at the antenna. The P3 showed two bands 
of increased noise floor that were each roughly 38 kHz wide. One was 62 
kHz above center freq and the other was 62 kHz below center freq. These 
noise bands were always present, regardless of operating band or center 
freq, with the same width and at the same distance from the center freq. 
If you're seeing signals invariant of the center freq then try a 
different BNC cable. If that doesn't help take a close look at the BNC 
receptacle on the P3 to see if it is damaged.

Certainly it is not flat (or is it?), but mine was so ugly that I moved it down off the screen...hmmm, might be time to try a different bnc cable. My radio isn't set up at the moment as I remod my shack, but I remember hearing signals that were too small to be seen in the grass. Thanks, Jim WN8A
