[Elecraft] P3 Noise signature

[Dave Van Wallaghen]

Thanks Jim - I should try it. I have never tried to curb it mainly 
because it is usually off when I'm in the shack. This is a 10 year old 
Panasonic set and I seem to remember reading on the RFI list a few years 
ago about a couple of guys trying to work on their sets. As I remember, 
they said the set (screen) radiated most of the RFI and that putting 
toroids on the AC line did not help.

But you can never have enough #31's around so it won't hurt to try it 
here! It is getting pretty close to replacement time for this thing 
anyway. A much lighter (and a little bigger) LCD is in the future ;-)

Thanks again & 73,
Dave W8FGU
