One known source is a pool pump, no longer a simple induction motor, but something more exotic a couple doors down. Occasionally it goes off, and things clear up noticeably, though not completely.

It's worth many hours chasing down and eliminating all of those noise 
sources -- they're also raising the noise level on the ham bands.
