I was out running errands today and got a call from the utility. They think
they found and fixed the problem and wanted me to check to confirm the noise
was gone. As soon as I got home, I powered up the rig and sure enough - noise
is GONE!
I relayed this back to the utility guy and asked him what they found. Turns out
it was a bad lightning arrestor (as several suggested) a little less than 2
miles due north of me as the crow flies. I thanked him profusely for their
efforts and he told me to call him directly whenever I have a noise issue.
Happy ending to 2024!
Hope everyone has a wonderful 2025.

Thank you all for the suggestions.
I have contacted a fellow ham who lives a mile of so from me and he has the
same issue. He has been in contact with the utility, PECO, and gave me the
guy's number, I called him this afternoon. They have been out "hunting" but so
far have found nothing - looking for needle in a haystack - he tells me.
I do not have any portable equipment other then the Tiny SA that is coming
(which I bought to tinker with). The only thing I can tell from my station is
that the peak is just about North of me swinging the beam around. Strongest on
20 meters, CW portion. I can still hear it on 6 meters but not as strong.
Mike,
I will call you to discuss / pick your brain, (I see from your website you have
dealt with PECO in the past).
I'll supply updates as I get them.
Thanks,
Tom

I just picked up this message on the thread and didn't see where it originated
but the recording that I just played is most definitely power line noise. By
that I mean it's being generated by your power electrical utility outside of
your home. If you want to call me for further information or instructions or
points to ponder just give me a call if I don't answer your call please leave
your phone number. I'm on the phone a lot and traveling a lot. Best wishes

Yes, the RFI is related to the power grid, either in-house or somewhere else.
Therefore, don't spend more time identifying what is causing the
interference, but go looking for it. Any more sleithing as to what is a
waste of time and effort.
As broadband as it is, I doubt it's a switcher, but more like a discharge on a
line somewhere. But everything connected to the power grid is up for grabs.
