WOCR (89.1 MHz) — branded 89-1 The One — is a non-commercial FM campus radio located in Olivet, Michigan. The student-operated station, on the air 24/7, broadcasts on 89.1 FM and is owned by Olivet College Board of Trustees.

The station operates with 500 watts of power centering on the immediate Olivet area.

WOCR came on the air in 1975 as a 10 watt FM educational license radio station operating at a frequency of 89.7. Charles G. Mefford was the first general manager, obtaining an FCC license and the WOCR call letters, building the studios/tower and training a staff. He put the station on air with the help of Olivet College professors, Robert C. Fisher and Willis "Bill" Seldon and the eventual second general manager and student, Michael Oyster. A new transmitter a few years later took WOCR up to 125 watts of power until October 2010, WOCR operated on 89.7 with 125 watts of power. In certain areas the station would interfere with the signal of 89.7 WLNZ in Lansing; the frequency shift to 89.1 has alleviated this issue. WLNZ has since been granted a construction permit to increase power to 1,000 watts from its current 420.

WOCR "The One" is a full-service campus radio station featuring music, campus information, and sports programming, including play-by-play of Olivet College and local high school teams.

WOCR is the official station for Olivet Comets football and broadcasts all home and away games.
