I'm in the middle of a city, so there are no electric fences or horses
nearby.
I was able to hear it with a portable receiver just now. As I was
standing near a neighbor's house which seemed a likely source, it just
stopped. A few minutes after I got home, it started up again. Assuming
it persists, I should be able to track it down and post the results.

How close to somebody with a large fenced horse yard do you live?
Sounds like an electric fence charger cycling.

I'm hearing a new local RFI source. It produces a 1 second burst of
broadband noise at regular intervals of 3.5 seconds. I'm hearing it on
80 through 15 meters. In AM mode, it sounds like it's modulated at 120
Hz. It's very broad-band, so not likely a switching supply.
Any ideas on what kind of device might be producing this?
