Hi Ken,

I totally agree with Frank, and I would never report anything to anyone
including the power company until you are 99.9 percent sure you have
identified the suspect property.

Regarding power line interference the only time I called local power
company without knowing the exact power pole responsible for a problem was
when I had 2 very closely spaced power poles and could not eliminate one or
the other as being the root cause of the problem (they were just a feet
apart from each other).

I don't think any of us have mentioned the obvious first test that should
have been done, and that's to kill entire power to KC4Ds house (including
UPS systems) and power his receiver with a battery to make sure the problem
is not from within.

P.S. were you able to hear the noise from just outside KC4Ds house with
your portable equipment when not located near overhead lines or near his TX
antennas?  If so you should be able to confirm direction of the noise (or
at least the two possible directions it could be coming from, and did it
match up with what his beverages yielded (about ENE)?  If so, then were you
able to go to a clear field in that general direction but off to the side
to get another set of headings, etc?
