I also had a Plasma TV, a 42 inch Visio purchased many years ago, and had the terrible RFI problem on 80 meters especially. My 80 meter dipole hangs across the house , one leg over the plasma. I never operated much in the lower bands where the RFI was worse, but figured I would eventually get a LCD or LED TV and the problem would go away.
Well, the day came and I was itching to get a larger screen TV. I saw another Visio (they have good clear displays), so I thought I would opt for a LCD 55 incher. i had forgotten about the RFI problem with the plasma, but heck, this is a LCD so it should not have any problem. I got it home and really liked it. Well, as you might expect, I was on 80 meters working some CW one night and on the P3, I saw these little spikes, maybe 160 KHz apart (-85 dBm +/- a few dB). I hollered at my wife to turn off the TV and well, you guessed it, the spikes went away. So, in my case, an LCD TV does have some RFI, although not as much as the plasma. Interesting, a 32 inch LCD Visio in the shack has no RFI as best I can tell and the dipole goes directly over the shack. ----- Roger W5RDW -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Plasma-Question-tp7562401p7562432.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
