Founded in 1966 by Donald E. Benson's Mighty-Mac Broadcasting Company, WIDG was just the second radio station to launch in the Eastern Upper Peninsula of Michigan The station was known for many years as "Widge by the Bridge" and aired mainly middle of the road music, at times a blend of top 40. The nickname "Widge by the Bridge" was coined by a longtime friend of station founder Donald E. Benson, a Lansing-based dentist who thought WITL-Lansing's slogan "Whittle while you work" was something that WIDG needed. The original CP for the station had the call letters WSTI, "St. Ignace" but Benson felt the call letters looked like "Stye". In the late 1970s, Benson obtained a construction permit for an FM station that would become WMKC. Construction on the new FM station began shortly after the license was granted on July 30, 1979; and in December of that same year, Benson also obtained a dark license for WIDG and kept the station dark until April 1981, when he was required to return WIDG to the air in order for WMKC to come on the air. WIDG returned with an MOR format until a format change to Big Band and standards and the call letters WLVM. In 1985, the station returned to the WIDG calls with a top 40 oldies format until 1988, when WIDG simulcast sister FM's WMKC St. Ignace and WCKC-Cadillac's country music format. Eventually, in the early 1990s, WIDG once again adopted separate programming from WMKC, airing first oldies and then classic country before the sports-talk format was introduced. WIDG was initially an affiliate of One-on-One Sports before switching to the ESPN Radio feed. WIDG operates with an omnidirectional antenna and with very low power after local sunset to avoid interference with the now-defunct CINW in Montreal. In WIDG's heyday, it constantly fought for a good signal into the north and was stymied by 10 kW CKCY-920 Sault Ste. Marie, Ontario. WIDG's signal was obliterated by CKCY north of Rudyard. When CKCY went dark, WIDG finally got the full potential of its 5 kW signal and can be heard well into the province of Ontario. Though CINW has been silent since 2010, WIDG must still power down from 5,000 watts to 4 watts at sunset per FCC rules. In October of 2019, WIDG and its sister stations were acquired by Immaculate Heart Media, bringing Relevant Radio programming to Northern Michigan.
Baraga's main studio and offices were originally located at WTCK's studio at Indian River, Michigan near The Cross in the Woods Catholic Shrine. It also airs national programming from EWTN Global Catholic Radio and Ave Maria Radio based at WDEO in Ypsilanti. In the fall of 2014, Baraga Broadcasting announced plans for a new website which is now online and was used in transition from its former Indian River location to new studios in Traverse City, Michigan thus making WTCY which serves Traverse City the new originating station.
