Don, they should force mfg to recall all plasma TV's. I have one next door,
it's a little more than 150 feet from my shack, the noise from it is S-9 on 75
meters. DXing is good on 75 and 40 till about 6:30 AM when the TV comes on,
it's a kitchen TV. It's on all weekend long, I get relief during the week for
a few hrs after about 8 AM, otherwise I am on the upper bands where the
interference is not as bad. IT IS a bummer to say the least. I refuse to be
the bad guy and make enemies of my next door neighbor, I feel it is NOT my
responsibility to quiet these ill-made plasma TV's. THAT is what we pay
government agencies for otherwise why keep funding them at all.
73 and thanks for the attention
