[South Florida DX Association] Plasma TV --- Mother Of All RFI Producers

[Bill]

In tests the link did not go all the way to the article. If that's the 
case scroll down the left colum and you will see the Tech Notes and 
there you can find the articles....the link did not work when I sent it 
to myself directly either, so scroll down and enjoy the article. Good 
reading as well as all their Tech Notes...

Hi Bill,

Just in case your email client didn't parse that URL correctly:

With an indoor antenna I've become acutely aware of RF noise sources 
around the home.
- Any of the new TVs use switching power supplies which emit noise all 
over the spectrum.
- Lap top chargers are incredibly noise, especially when charging a 
depleted battery, expect
   noise  to past 5-6 GHz!
- Computer power supplies.
- The new Compact Fluorescent Bulbs  (CFB)  are big HF polluters, so are 
Fluorescent tubes.
- Light dimmers are especially noisy as well.

Fortunately, many of the new LED bulbs are quite, especially if they do 
not use switcher supplies.
