I often "FM band dial twiddle" whilst long distance driving. I not infrequently note some unidentified distant FM bc station totally overriding for a variable period of time some also weak FM station i am listening to. AM bc stations are so well freq controlled now that if there's any audible beat, your best guess is that one station is Mexico or overseas. You can hear both audios at once. Yes, it is hard to sort out, maybe impossible, but both - or more - are in there.

Re AI - it seems that Ebay has done a good job selling it to the rubes. These glowing AI listing descriptions all sound so alike, very high BS factor.
