Hi,
See:

That will get you started... It is a single part of a three part series on dealing with RFI.

Hey folks,

                 I don't work a lot of 20 meters, but was thinking I might use 
it during Field Day for a 1E operation. I have some 'noise' that starts around 
11 MHz and gets stronger as I tune up the band. It is about S8-S9 across all of 
20 meters and finally plays out around 15.600 MHz. I made a video showing the 
issue and placed it on Youtube here:

                 I have preformed tests turning the breakers off to my home one 
at a time as well as turning the master breaker off and running the radio from 
a battery. The noise is unchanged by this. The noise is there 24 hours a day 7 
days a week.

                 The antenna is a simple ground mounted vertical in my backyard.

                 Any and all help and suggestions are appreciated.

Thanks and 73,
Gary "Joe" kk0sd
