@jerzone Huh. Never knew about that, but then I was still using a walkman type device in those days. I did have the gizmo shaped like a cassette cartridge with a wire and headphone jack for use to convert your walkman to send music to your car's cassette player.

@bosquebill I'd use it on cross country trips, but near any sizable city it was too much of a pain trying to find a usable frequency. Cassette converter much better quality if the car had a player.
