KURE

88.5 FM KURE is a student-run radio station broadcasting from Iowa State University in Ames, IA.  They went on the air in 1949 as KMRA and went through a host of other call letters including KMRI, KISU, KPGY and KUSR before becoming KURE in the mid-1990s.  It's unclear if the station was named for the band of college radio faves with (almost) the same name or if they had nothing to do with it.
KURE has an event called Kaleidoquiz which they've held every year since 1967.  KQ is a 26 hour marathon trivia contest which now encompasses scavenger hunts, murder mysteries, physical puzzles, photo/video challenges and prize giveaways all taking place while a new question is asked every 6 minutes.  Teams are scattered around campus listening to KURE for trivia questions and instructions.
