WOBN is an American college radio station owned and operated on 97.5 MHz FM by Otterbein College in Westerville, Ohio. The station's studio is located at 33 Collegeview Road and tower is located at Cowan Hall on the campus of Otterbein College. The station began operations in 1948 as an AM station with the callsign of WOBC. In 1968, the station's programming moved to the FM band on 91.5 FM. In the early 1980s, the station changed frequencies to 105.7 MHz - a frequency located within the current commercial portion of the FM band. In 1989, the FCC required that Otterbein relinquish the commercial frequency to make room for a new commercial station in Marysville (now licensed to Hilliard as WBWR-FM). In 1990, WOBN-FM moved to the frequency of 101.5 MHz. In November 2008 WOBN moved once again to the present frequency of 97.5.
