Mike, I have found that my small local electric company, which has zero capability for finding RFI sources, is great about coming and fixing them if I can identify the pole or the neighborhood (within a few poles).
My major source, now mostly fixed, was slack spans rigged with taut span hardware. These are commonly used where the primary wire needs to cross a road and there is no room to guy the pole counter to the direction of the cross-over. If the right hardware is not used, there is sparking between loose parts on the insulators.
If I were you, I'd look for slack spans in the direction of the interference and report the pole numbers. It wasn't until I found them all and got them all fixed that my noise environment calmed down.
73, Pete N4ZR
