I take it, that this is a broad band noise. Does it cover 160 and all
the way to 80, or just the two bands? Does it cover the entire band(s)
with the same strength? How about the broadcast band? Strong station
nearby? Any noise lower than 160?
An arc, even a low voltage on on a wire, piece of wire (guy for instance
or an antenna), particularly if its anywhere near resonance.
Power pole grounds?
How about a voltage differential in the ground, causing a poor
connection to the tower to radiate. Poor solder joint with DC or AC to
a remote antenna switch. In this case it sounds like it may not be an
obvious source.
We have occasional Fox hunts. Could you put together a team to hunt for
the source? (With someone coordinating)?
We've hit the bottom of my well<:-)
73 and good Luck!

And can it be prevented? Trying to track down a loud “buzz” on 160/80.......I used to be able
to kill it by turning off the breaker to my outdoor pole light with a photo-eye on it......now, that doesnt
even phase it.....found several sources in the house last night (cfl bulbs, a bad flourescent tube,
external hard drive power supply) but none even touched the noise I was hearing.....so today, had a little
time when I got home from work before dark to walk around the yard with a portable SW radio.....thought
maybe it was pad moount power transformer in the neighbors yard, nope...tried the power ped in the corner
of my yard, nope...maybe my relatively new “smart” power meter, nope.......then as I walked
past the tower, I picked up the buzz in the portable......really bad the closer I got to the
tower......thought maybe it was one of the cables, nope.....it seems to be coming from the tower, 50ft Rohn
25....is that possible? Is the tower picking up RFI from a remote source and re-radiating it? It certainly
couldnt be generating RFI could it?
