sorry about the double post
I live in a rural area that is full of 3-phase transmission lines and only
this particular 2 mile square section has noticeable interference. The power
lines are owned by a small rural coop utility company so I think they are
motivated to resolve the problem if it is theirs.
What are the references to BPL?
thanks

I posted a few months back about this problem and have narrowed down the
root cause. The symptom are an overpowering hum at the low end of the am
band. It's being caused by a 3-phase distribution line. I can follow
this line in any direction for several miles any time of day with any of
my vehicles and get the interference. I contacted the power company and
supposedly they're going to look for the cause. Has anybody else dealt
with this type of problem?

Surely this is normal on AM near power lines, particularly high voltage
ones.
