The original call sign for 88.5 FM's construction permit was WAAQ, but the station was never on the air with those calls. It signed on as WDQV, "88-Dot-5 Dove FM," airing a satellite-fed contemporary Christian music format from Salem Communications ("Today's Christian Music"). Interlochen purchased WDQV in March 2005, and after a brief period of silence, 88.5 FM became WIAB, simulcasting WIAA, in July.
WIAB was formerly simulcast on a translator in Mackinaw City, W237CF (95.3 FM), which was formerly owned by Xavier University and then Cincinnati Classical Public Radio as a translator of WVXU 96.7 FM (now WRGZ) in Rogers City, Michigan. W237CF, now on 95.1 FM as W236BZ in St. Ignace, is now owned by Baraga Broadcasting and simulcasts Catholic radio station WTCK in Charlevoix.
