A new source has just shown up:

The harmonics are about 8 kHz apart, which is awfully low for a SMPS, though that's what it looks like. I'm only hearing it on 80. It's not coming from my house, but I have many nearby neighbors. It's definitely local. So far, I haven't been able to detect it with a portable receiver, but I need to do some more tracking. Any ideas on what this might be?

73,
