Just a quick repeat of my comment earlier - you can't just turn off the
PC and the monitor.  You must remove all AC and backup DC power from
them.  I had a monitor that spewed noisy carriers all over the place and
the only way to quiet it was to pull the AC plug.  Simply powering it off
made no discernable difference.  Threw me off until I used a portable
radio to home in on the problem, and when I pulled the AC cord, the QRM
disappeared.  It got replaced with a nice quiet LED monitor.

73, Duane

Hi Jim,
Have you tried turning off the computer? I suspect if it's
coming from the computer system it's the monitor. I have a lot of
monitor noise on the TV with this monitor and some on spot
frequencies on HF. Yes it could be the cables. You could slip
some braid over the leads and ground one end, that will usually
take care of cable radiation. I've never found the snap-on
ferrites to do much. 73 Jim K4CGY
