This is a radio station in Sacramento which is run by highschoolers, with a 10-watt (mono) transmitter reaching a 5-mile radius. I haven't been able to find an Internet stream anywhere, but it's a great listen if you're ever in the area. There were a few dedicated weekly shows, but the bulk of the programming was just whatever the kids wanted to play, punctuated by haphazard and occasionally awkward or goofy airbreaks. They were constantly dropping stuff that was totally off my radar.
