I hold an AM pocket-sized receiver near the mains in mysuburban home with
underground AC mains (utilities) and I hear overwhelming white noise that
degrades the SNR on major stations in this market even ... different tones and
rep-rate cyclic noise can be found at different spots. 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.
On weaker in-the-market stations I have to find the right position for the
pocket portable AM receiver for a reasonable SNR (w/o the white noise and
cyclic tones.)
