This RFI source has appeared recently:
https://sdellington.us/hr/RFI/24.07.31.png
It appears to be harmonics of about 78 kHz. However, unlike most SMPS
RFI, it is very stable. It disappears at night, suggesting a solar
system, but it persists, weakly, an hour or so after sunset. Maybe a
solar system comm link, with a supercapacitor? However, I'm not aware of
any new solar systems nearby. Anyone seen anything like this before?
Needless to say, I'll be out tracking it soon.
