WRMU began as a carrier current station at Mount Union College (now known as the University of Mount Union) in 1966. FCC approval to broadcast at 91.1 FM was granted in 1970. The station is student-run but programming is aimed at the surrounding community as well as MU's campus with Smooth Jazz during the day and Oldies on weekends. Students pick their own music at night when the "After 10" DJs take over. WRMU is licensed to Alliance, Ohio.
