Hi Ken,
I think you need to take a step back. No matter were you look you will
find sources of interference. The question is what source of interference
is causing your problem. Therefore the first questions that I would expect
you to answer would be as follows :
1) Is it broadband (like 100 khz wide or more versus located on a very
specific frequency or frequencies), and what is the frequency range that
you hear it?
2) Is it on continuous or does it sometimes go away?
3) If broadband does it go away when it snows or rains?
4) Is it local (groundwave)?
5) *What direction from your house is its heading*.
You are a very smart guy, and if you have not answered the above questions
then you need to do so before you go any further. It does not matter what
you think the source is at this time, and don't depend on "he said she
said" stuff that people are saying around town. What matters is
identifying *what direction it is from your location* and then narrowing it
down to within a city block or smaller via DFing. Until you have done this
there is no point wasting resources (FCC, power company, etc.).
Note : when determining what direction from your house it is heading you
really need to make sure existing antennas and other metal structures are
not fooling your DF antenna. I normally walk out to the center of the
street (making sure I don't get hit by a car) or large field with my DF
antennas to make sure nearby metal structures are not re-radiating the
signal and tricking me out (HF antennas, rain gutters, metal chimney flue,
aluminum siding, house wiring, above and below grade utility feeds, etc.
can couple to your DF antenna or re-radiate the signal so you have to make
sure you eliminate their influence). You also need to make sure you
determine this heading when you are in eye shot of your house (don't drive
a mile from your house, get out of the car, and determine a heading from
that location as it may or may not be the signal that's causing problems at
your QTH).
I still am interested in hearing and seeing a youtube video of the noise
when you get the time.
73,
