Make sure you check thru your own house. Run off a battery if possible and shut
off your electrical breakers one at a time and check for noise each time. Had
one just like this and it turned out to be a bad wallwart transformer.

Hi Fred,
Do you have a police radio scanner that covers the aviation band? If so it
makes for a great 136 MHz AM receiver that can be very helpful in narrowing
in on the faulty pole especially when a portable directional antenna is
connected to it (especially if you can throw in 20 or 30 db of

have my work cut out for me. I think it's coming from the south. My South
Beverage picks it up the strongest North Beverage still strong but little
weaker. On 40m I have 2 full wave loops and the n/s loop picks it up
Power pole noise can be difficult to find with a portable receiver that
is not directional. It's also difficult to find when all you have is an
ultrasonic detector because those have to be pointed right at the source
to hear anything.. Power lines make a good antenna for radiating power

Hi Fred,
Google: 160 meter receiving loop antennas
You'll get lots of good ideas for antennas you can build in
just a few hours with simple parts.
An 8 foot diameter loop will provide the best sensitivity,
but a smaller 4 foot loop will provide deeper nulls
You'll need a good preamp
Thanks everyone for the help/info.
The noise is there almost all the time the only time it stops is when it
rains.
In my video the it just stopped raining and it was just getting going again.
I wanted to show the noise when it was not there too.
I know one of the guys who are involved in
You could always run open-wire feedline the 620 feet.
