There seems to be dozens of noise sources in my neighborhood, to the point that radio and TV reception is no longer enjoyable, and DX is impossible.
Trying to locate the sources is nearly impossible, since some seem to change constantly.
Many problems are due to faulty outdoor lights in the apartment complex...curly florescent bulbs that were installed in place of incandescent, and decades old High Pressure Sodium Vapor lights that (should) illuminate the parking areas (except they only illuminate for a few seconds at a time while cycling on and off).
Add that to the thousands of daytime lights (24/7) in the huge mall across the street, and there's noise constantly...even in to the VHF TV bands.
I've reported the apartment lights to my landlord numerous times, even giving them written lists of the problem ones. They always smile sweetly, and promise to take care of it, but never do. Other times, they say they are hoping to budget for new lighting "next year or so", but nothing ever happens except cosmetic changes to the grounds ("curb appeal").
Managers change every year or so,
so promises mean nothing.
