Guessing will also ruin your relationship with the local Power Company as well, not just for you, but in a lot of cases for ALL hams in your area... So do be careful...

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.

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:
https://www.youtube.com/watch?v=GKf4P44FXMo

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
