WOCR (89.1 MHz) — branded 89-1 The One — is a non-commercial FM campus radio station located in Olivet, Michigan.
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.
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.
