Mike,
Thanks for the info. I understand locating the noise is more
important than identifying the noise. I am just try to play all the angles as I
was hoping to work the WPX contest nest weekend. I have been walking the
neighborhood a good chunk of the afternoon, and have not been able to hear the
noise on my portable shortwave and loop antenna. It is as strong as ever on my
home station.
I have an MFJ 852 Noise Finder and it seems to go crazy when
broadside to any house. The neighbors on each side of me drive the meter full
scale.
Yep I only want to knock on one door, as I know that can get
dicey. I would rather place a call to a utility, but can’t really do either
until I know.
Keep the suggestions coming!
Thanks and 73,
Gary “Joe” kk0sd

Joe I haven't had time to read all the other input but I can tell you it is not
an arcing source or a sparking source. either one of the two would be much
broader than what you're reporting. if someone were to tell you exactly what it
is you really wouldn't be any further ahead. You would still have to find which
residents or business it's in. My suggestion would be to either go mobile or on
foot, preferably on foot listening to the frequency that you know the problem
affects. once you locate the residents then go through the breaker scenario and
locate what the source is. Be 100% certain of the structure or home that the
problem is in before knocking on the door. The last thing you want to do is
start guessing. Guessing we'll ruin the relationship with your neighbors.
Be safe,
Mike k3RFI

My last problem was tracked down to a neon sign in a neighbors garage. I had
several months of blissful relatively low noise operation, but now have a new
RFI issue.
You can see a recording of it here:

I have turned all of the breakers in my home off and run the radio from a
battery and the noise remains.
My neighborhood utilities are all underground.
There are no solar installations in my neighborhood, and the noise is there at
night anyway...
The noise is not detectable on the AM broadcast band, but starts around 2 MHz
and runs to at least 6 meters.
It is there 7 days a week 24 hours a day.
It is not detectable from my pickup when I drive the streets of my neighborhood
(checking both AM broadcast and Shortwave).
If any one has heard something like this, I would love to hear what you found.
Thank You for your input and help!
73,
Gary "Joe", kk0sd
