The best solution that I can offer is to replace it with a TFT (LCD)
monitor. Takes up a lot less space on the operating desk and does not
generate so much trash in the RF spectrum. I suffered from the same thing
for a long time and finally just bit the bullet and bought one - I have been
very pleased.
I agree. Recently I had to buy a new computer for my XYL, who already
had a flat-panel monitor. Dell offered a nice one for $100 with the
computer, so the old one ended up in my shack. It definitely is more
RF-quiet, as well as being easier on the eyes.
Having said that, most of the noise from CRTs is radiated by the cables.
I would wrap as much of the power cord and video cable as possible
around big ferrite cores. If your problem is mainly on 160 or 80 meters
you might best use the 43 mix, which is more effective at low
frequencies. Simple snap-on beads are ineffective at HF. My attempts
to shield the whole monitor with aluminum foil, etc., also did not
produce good results.
