Steve -
I had the exact same issue with my (now deceased) Samsung 24" LCD
computer monitor.
What fixed it was running the AC power cable 6 turns around a "Big Clamp
On" ferrite. See Jim K9YC's doc @
http://www.audiosystemsgroup.com/RFI-Ham.pdf.
Prior the hauling out the Big Clamp On, I'd tried two smaller clamp on
ferrites, with no measurable effect.
I also use a Big Clamp On ferrite on a touch-lamp that my wife uses; it
turns on and off in sync with my transmitting on various bands unless
the power cord is choked down.
Thanks again to Jim for sharing his generous research!
73/HNY to all,
Steve
