[Elecraft] Plasma TV Noise any ideas on how to filter it out.

[Steve Ellington]

Same thing here but the neighbor is no help other than allowing me to buy 
them a new TV. Theirs is a Samsung 58" plasma. Forget using any kind of line 
filters. The noise is radiated from the SCREEN....straight out.
After months of experimentation, the only cure has been the MFJ-1026 and it 
works magic! Having a K3 with LP-PAN or P3 makes adjustments easy. Otherwise 
it would be a real pain to tweak.
You do need decent noise receiving antenna for the 1026. The K3 has the 
RX-IN/OUT jacks which allows to interface the 1026 with ease and retain your 
QSK without using the MFJ internal relay.
Contact me for any further info. 73

My next-door neighbor was probably one of the early adopters of plasma TV
several years ago.

One night at bedtime I switched on the AM radio and was met by severe buzz 
all
over the dial. Not a single station was listenable. I could hear the buzz 
all
the way up to 10 meters. It only took me a few minutes to determine that it 
was
coming from my neighbor's house.

I informed him the next day. Lucky for me, he is the type of guy who can't 
stand
the idea that a brand-new device of his is causing pollution-- he saw it as 
a
defect. And, of course, his own AM radios were affected, too. He had a 
Panasonic
tech out there in a couple of days. I don't know what the tech did, but he
managed to reduce the noise by about 10 dB though he never eliminated it
entirely. I've had to live with it ever since.

Since then I have said that the two things that have the most potential to 
kill
HF ham radio are homeowners' associations and plasma TVs.

Pray that your neighbors don't buy one of these evil devices.
