Is this noise broadband, or is it concentrated in
frequency, and then showing another concentration at
say 200 Khz away? My VCR when off was this last way,
and the pulse rate would vary just like you said. One
of those clusters was centered at 3885 (abt 15 kc
wide), and this would vary maybe +/- 20 Khz depending
I tracked it down pretty quickly with a cheap
Chinese SW portable I picked up in Shanghai a few
It's amazing how much stuff we have sucking power
in our houses 24/7 just so that we can turn something
on with a remote. Count all the wall-worts, and other
gizmo's, and I bet it adds up to over 100 watts all
the time. Some of this junk is now using switching
power supplies with little or NO filtering. Sigh.
Good luck with finding the culprit!
