Hello, Computers are very noisy, but I think monitors are worse, I read
the
plasma screens are quite. I have to shield a lead to the PC for data
decoding, I have ferrite rings that the wire is wound round and some beads
the wire threads through. I also have the radio in a foil covered
cardboard
box with holes for wires, the radio and the box have a good earth wire
to,,,, water pipe earth.

For the fellow with the whistling radio, If you could try another power
source. Wire a battery pack, or a car battery to see if the noise is still
there, get true DC. If it goes get a proper ham radio type shielded PSU a
good one will have filters to stop the noise rubbish. All the best.



Wow, sound more like to me you're just trying to build the worlds most
complex bong to smoke pot out of. :0)

Sorry I couldn't resist and I'm sure
you are not the sort of person to
allow any of that demon weed to
pass your lips.

My apologies sir.
