This is very true. A typical SVGA copper cable puts out all sorts of
hash (as well as the monitor!). And lotsa junk is radiated and
conducted out by the power supply cable, even for the "best of the
best" PC clone supplies.

I've discovered and/or engineered some workarounds, consisting of
going
to optical fiber instead of metal whenever possible. But my
converters
are usually outside the PC case so this doesn't completely eliminate
the radiation from copper cabling.

I'm starting to think I should just sit inside the Faraday cage with
my
computer, and put all the radios outside!

Tim,

You are really close to your own answer. I built a Faraday cage area
around my laptop. And also plugged into a surge/noise filter for
the AC and use metal hood cables to hook up to the radios.
I hardly experience any noise at all.

The reason is most manufacturer are turning to plastics and putting
less and less shielding in them. Keep in mind the OEM's are building
for the general public.
