Plasma TV --- Mother Of All RFI Producers on HF bands
Plasma screens are nothing like LCDs. LCDs use low voltages to twist
the crystals. Plasma screens use very high voltage high frequency current to "egnite" the tiny cells of plasma. That can make a pretty effective transmitter.

Plasma TV --- Mother Of All RFI Producers on HF bands
It all adds up, but after reading through all those old posts about Plasma
Screen TV - the evidence was not convincing, except the one chap who obviously has a problem with his own set. I work for a comsta that has large PSTV's surrounding the opcenter and receivers, and there is no effect whatsoever from them. When I got rid of my old lunker computer monitor for a flat screen LCD, it reduced the RFI from about 30 frequencies to 5. Just the same, I don't plan on addding a pstv to my home anytime soon, I'm trying to minimize rfi not test the limits, lol. Jack Va Beach "Larry W4CSC" wrote in message ...
