The solution is to buy the neighbor a nice large-screen LCD TV with
the condition that you get his plasma TV in trade. Sell the plasma
TV to someone a long way from you. You probably will not net
completely your costs in this.

This is only slightly off-topic, but since I do operate a K3, it still fits -
kinda!
We have two plasma TV's in our home. One is a ten year old Sony 42 inch unit.
The other one is a two year old Samsung 63 inch TV. They are about 50 feet from
the shack, and only eight feet away from each other
Jim,
Plasma TVs are wideband signal generators, and almost certain to cause
QRN. Go for a good LED TV and things will be interference free. Yes,
the plasma TVs are less expensive, but if you value your on-air time
while the XYL watches TV, you will need to use something other than a
plasma

Jim,

If you are a ham, just say NO to plasma TV. Even if they have a generally
successful shielding scheme, YOURS could just have one little defective
connection whose only outcome is noise. Techs will never be able to fix
it. You have to take it apart to work on it. Taking it apart disconnects

Matt,
Quite interesting. In my situation, the nearest neighbor is 1/4 mile away,
so hopefully the effects of a plasma TV will not be apparent to me

Indeed!
My neighbor bought a large-screen Plasma TV about 6 months ago.
When he's watching it (most of the day!) it blocks out large chunks of 80m and

His TV is about 40ft from the middle of my dipole and about 30ft from my gear.

I also had a Plasma TV, a 42 inch Visio purchased many years ago, and had the
terrible RFI problem on 80 meters especially. My 80 meter dipole hangs
across the house , one leg over the plasma. I never operated much in the
lower bands where the RFI was worse, but figured I would eventually get a
Anytime there is high-speed digital logic in operation there is RFI being
generated. After all, those logic signals are no different from a square
wave RF signal, and being square waves means they have very high levels of
harmonic energy across the spectrum.
The big difference is that a plasma

Experiences in the UK and across Europe are that Panasonic Viera Plasma TV's
are particularly bad at causing interference to the radio spectrum.
There are more energy efficient and pollution free alternatives available.
