I have a neighbor a couple of hundred yards (yes, that far) that away that purchased a plasma approximately 15 months ago; since then, when it's on, I have s7-s9 noise from the AM band through 80m (at various points). I offered to purchase a new LCD display for him to replace it, but he "likes the way it looks better than any other". I don't expect to be able to obtain relief short of FCC intervention. It even interferes with vehicle AM radio while driving near his house. While the ARRL recommends to work with your neighbor to try to solve the issue (with ferrites and the like), I don't believe this advice is in tune with today's social conventions, liability laws, "last mechanic syndrome", and the like. I would be reluctant to touch anything on anyone else's equipment lest I be responsible for any future real or perceived issues with proper operation. I think the only effective solution would be to 'go nuclear' and get the FCC involved; what I find is that I just operate less.
Quite the bummer, because my favorite band over the last few years has been 160m.

When you get near a plasma you will hear it. The LCDs are fairly quiet. Plasma set noise comes right off the screen and is strong enough to be heard for some distance. The only cure is to unplug the TV. They even radiate some when turned off! I believe my neighbor has a Plasma set. It wipes out 80 meters mostly. I plan to find out soon and if necessary I'll help him replace it. 73 Steve N4LQ ----- Original Message ----- From: "Chris Hembree" <[email protected]> To: <[email protected]> Sent: Friday, January 21, 2011 7:56 PM Subject: [Elecraft] (Very OT)Plasma TV noise >I am helping a friend track down some RF noise that is riding on the Cable >TV line.
