Hi guys, my K1 is picking up hash on most bands from a pc which is in the
upstairs bedroom about 12 feet away. After conducting a few tests I have
found that the radiation is from the monitor lead. With the monitor
switched off and lead connected the hash is still there but if I disconnct
the lead from the pc the hash drops significantly. The lead has the normal
split ferrite on it and I had another one in the box so tried that but with
no difference. Is it worth me buying a large ferrite ring and trying to
wind a few turns on it. On the monitor end the lead is not disconnectable
and at the PC end has a moulded-on multi pin plug which means you need a
fairly big ferrite ring to get the plug through (not cheap).
Anybody have any advice?
