You can buy a TV for the neighbor and if he cooperates that's fine. But they don't always cooperate. Sports fans like plasmas because they have no latency effects in fast live action. And sports live action when the screen is constantly changing is when they blast out the most noise.
The screen radiates because it is the nature of plasma. Every little pixel is a gas bubble that is fired by around 10KV to ionize the gas inside to emit light. It's a matrix of thousands of arcing electrodes. The h.v. supplies are often unfiltered and their noise is coupled to power lines. If the TV is wired to the phone and internet to display in-coming call ID when the phone rings, out goes the noise on the phone lines. Now you are surrounded. You can buy the TV if they'll go along, but what's next--grow lights...solar panels...variable speed furnace motors... You can't control everything and if you can't move to a QTH where you can establish a 500 foot buffer all around your antennas, you are left with trying to control how this RF gets into your systems. So far, I've had pretty good success with a pair of RF Pro-1B loop antennas and the DX Engineering NCC-1 phasing box. It won't solve everything but it knocks the noise level down to where it seems like it's the year 1995. But for those of us with these problems, the days of hearing QRP stations is probably coming to an end. Low band hamming is going to eventually become a luxury for those with a lot of land. I know hams who have already abandoned the low bands. The broadcast industry trade associations are trying to get action but it is probably too little too late. The FCC has not done enough to protect and defend the spectrum in the U.S. that is HF and lower. 73 Rob K5UJ _________________ Topband Reflector Archives - http://www.contesting.com/_topband
