Hi Dan, I get similar 20 - 30 dB above the noise (S8 - S9) carriers spaced out like yours. I don't usually get the wiggly wide bits. I cannot reduce them, even a little, with my ANC-4 noise canceller, so I don't think they are originating in my house. Mine seem to be 61 KHz apart on 20 meters. I have a bunch of small ones (5 - 8 dB above the noise) spaced about 10 KHz on 80 meters. I can't null these out either.
I have a bunch of smallish ones on 160 spaced at 20 KHz that I can null right out with the ANC-4, so I suspect these are wall-warts or other switching supplies in my house.
There are folks with solar in the neighborhood, but I can't be sure if that is the source. A couple of years ago I tried to correlate sunny days vs nighttime to see if there was a difference, but I couldn't see any particular pattern.
If I am having a QSO on top of one of these things, I usually just create a TNF and get rid of it that way.

Morning Len, thanks. these show up randomly any time of the day, not so much after the sun goes down. they move latterly. do not know if they are geophysical or solar. never seen a solar panel do this. its usually the inverter that makes the noise. catch you later. Daniel
