For those of wondering why, when driving, you heard oddball music, etc. near the start of the FM dial: it could be someone's Ipod/mp3 player via a mini FM transmitter, or someone putting their satellite radio through the same thing. Thus Stern winds up on "free" radio...often in the non-commercial part (88-92 MHz)

Many of these mini FM transmitters only operate in the lower part of the FM band but some offer the chance to transmit on any frequency...

example of a mini FM tranmitter--takes a couple AAA batteries and can broadcast at 88.1, 88.3, 88.5, and 88.7

Same thing can happen with XM satellite radios as well. I used to use the built-in FM modulator in my vehicle, but have since switched to a cassette adaptor.
