Anyone using any switch mode power supplies in your area? Or maybe Ethernet over powerline adapters? Could also be LCD TVs, CFL/LED lightbulbs. Hard to know exactly.

What SDR hardware are you using? If you are using an RTL-SDR, are you using AGC? Or perhaps you have the manual gain turned up too high?

I would say this is either powerline adapters, or images of strong signals such as nearby FM radios.
