Phil, W0XI, has put a kit ultrasonic detector on the market. Well worth
looking into.

Subject: Re: Topband: Noise problem question
I have used one which the ARRL RF lab brought down here to address a very
serious problem. We were able to identify the BOLT on the insulators where
arcing was coming from, photograph it, attach both the audio file and the
spectral display unique to each offender and the power company still
reneged. Until FCC saw this and that was the end of the power company
resistance. Problem fixed. Those devices are not easy to aim however. You
need a steady hand and lots of patience.
