Good advice from K4XS. I track all my power pole noise problems to the pole and since I built an ultrasonic detector, I can even identify the component on the pole that is causing the problem. When giving this info to the power company, the response has been amazing. The record repair time so far is under 3 hours.

Power pole surge suppressors have been the highest failure item around here.

With most of the guys coming out, you can't just tell them...I have an RFI
problem and you need to find it.

It is imperative you go out and do your homework.

The first suggestion is something you can't do...turn the beam around to
see where the source seems strongest.  usually there are multiple sources  so
this can be tricky.

Second, if you have a mobile rig, hit the road and using your AM radio as a
  starter, drive around the neighborhood.  When you start getting pretty
strong noise on the AM radio, switch to your mobile rig.  Turn it on AM to
the highest freq it will go.  Higher is better.    When it  peaks in a general
area.  You have a culprit.  Check to see if anyone  in your local club has
an MFJ "sniffer" or something similar.  With that  you can usually nail down
the problem to one or two poles.  Tie a piece of  survey tape to the

After you have identified the offending sources, call up the power company
again and tell them you know for sure which poles are the problem.  I can
tell you from experience they will be a lot more cooperative if you do this
sort  of thing.  You , as the one with the complaint, will seem more
knowledgeable, and you will find them easier to work with.

I am currently working with my local power company using the above method
and they have been very cooperative.  In FL we have lots of thunderstorms
and as a result many arrestors on the poles get blown.  If you can lead  them
to the source they MUST and will fix it.
