[RFI] LCD Monitor Interference

[Pete Smith <n4zr@contesting.com>]

Very interesting -- my generic 15" LCD monitor is completely quiet at HF, 
so far as I can tell, but today, I was listening to FM radio on a little 
clock radio.  We are in a fringe area, so the signal wasn't very strong, 
but it was full quieting.

When I connected the signal cable to the monitor, semi-white-noise 
interference could be heard on the radio.  Power down the monitor or shut 
down the computer, and the noise goes away, so I presume it is related to 
the minotor itself, rather than to the power supply.

This really isn't a problem for me, since I don't operate VHF, but I 
thought others might want to know.  The monitor is a LiquidVideo, sold by 
Circuit City stores.
