The station shares a tower with its sister GPB Public Broadcasting Service (PBS) member television station, WMUM-TV, in Cochran, its city of license.
The station is a partnership, established in 2006, between Mercer University and GPB.
The station provides local content to central Georgia public radio listeners from its broadcast studio on Mercer's Macon campus.
The studio, constructed in 2006, offers various media-related educational opportunities for Mercer students.
As WDCO-FM, the station only simulcasted the GPB radio network, with no local origination.
