Regarding power line noise.
It could be coming from some distance, say another street. I suggest
you go out one dark night and walk along under the lines and listen by ear as
well as radio and watch carefully at each pole.
I had a similar problem some years ago. If it is leaking accross the
insulator (ususally a cracked insulator) it may have a visible arcing.
I my case I used a large sledge hammer to hammer the pole and this would
stop it for some time.
If your power poles are metal try connecting a portable radio antenna to
the poles and the one with the leak should produce a very high level of
noise.
Perhaps the wooden poles would give the same result if you could get some
contact with the timber.
