Hi Kostas,
Two possibilities. 1) Direct radiation from the computer or the display.
2) Radiation from the cables connected to the computer or the display or
both.
Easy fix for #2 -- see k9yc.com/RFI-Ham.pdf and the applications note on
k9yc.com about killing receive noise. Multi-turn ferrite chokes on the
cables. No easy fix for #1 -- it's a design defect of the
noise-generating product. You've got to junk one or the other, depending
on which is the culprit.

Hello to all and Merry Christmas
We have a problem in my club's station. When I turn on the computer's
screen everything is ok in our Kenwood 950. When I run VE7CC's cluster
program I can see 3 s-units noise. I thought that it was because of
the white colour but this does not happen if I open painting which has
also a white colour as background. Any ideas where is the problem?
