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?
