All of this is great info. If whoever wrote the majority of this wants to
rework it to include all useful suggestions, I can add it to the ARRL pages on
power-line noise. I may edit it to include some of my own thoughts, based on
our experience, but will leave the attribution there to acknowledge the author.
Send it to me with an email that says that we can use it.

Hand-held UHF Yagi - can you point a Yagi at the offending pole with those
insulators and demonstrate THAT is the source of noise?
It's most convincing when you can swing the beam back and forth and
the noise picks up when pointing at the offending hardware.

I live near the territory boundary of two utilities. My work with PP&L has
fruitful and they have been very cooperative in resolving RFI issues i would
report to them over the years.
I have been struggling with MetEd for the same powerline noise for at least 5
years now. I recently got their attention again and reopened a new work order.
I spoke to their tech today and learned they have been replacing cut-outs and
repairing resistive connections. All good but my RFI issue continues mostly
driven by drier windier weather conditions, the RFI swamps the 25-150 MHz
spectrum.

There are old bell type insulators on poles near this suspected line area. I
consistently request they replace those problematic antiquated bell insulators
that are notorious for RFI issues. They(MetEd) seem to avoid this. With my work
with PP&L, replacing those bell insulators have completely resolved those
reported issues. The techs from MetEd use their ultrasonic detectors to find
issues but it is my impression these bell type insulators do not show up as
issues when they look around with their ultrasonic detectors. True statement ?
How does one convince a utility to actually listen to the RF spectrum for
issues ? Is there a specific model spectrum analyzer that the utilities tend to
use to scan for RFI ???
