I snooped on your QTH. Nice remote area with single phase lines. I am
jealous :-).

Thanks Ed and Charles,
With all the great input from Ed, I now know the "lay of the land", i.e.
what administrative tools and regulations apply.
I've located two power poles that are likely sources. I drove around
listening on my car radio to the noise in a clear channel in the AM
broadcast band. When the noise peaked next to a power pole, I got out of the
car and did some direction finding with a portable AM radio (that has the
typical directional internal antenna). Next, I verified the findings using
an MFJ-852 AC Power Line Noise meter. Everything was in agreement, so I made
note of the pole identification number (from its metal ID label). I've
already contacted the power company, and they've issued a work order number.
They said that it might take a week or two, and if needed, I should call
them back.
Hopefully the problem will now be fixed, although there were many additional
power poles that caused much lower noise on the car radio. But, this is a
good starting point for now.

I've recently become plagued by power line interference that is most
noticeable on 80M and 160M. In the past,, the local power company had been
cooperative in fixing the source(s) of such interference. However it's been
about 7 or 8 years since I've been in touch with them about such issues.
Just to be prepared, I would like to know what specific limits there are on
power line emissions (if any). I know that in the past, the requirements
were very lenient - only requiring power companies to follow good
engineering practice without any quantitative emission limits. In any case,
having the actual reference paragraph numbers in the FCC rules would be most
helpful. As I recall, this had been somewhere in Part 15. Any help would be
appreciated.
