WTCK (90.9 FM) is a radio station broadcasting a Catholic religious format. Licensed to Charlevoix, Michigan USA, the station is currently owned by Baraga Broadcasting...named for the Catholic missionary to native American tribes and later Venerable Bishop Frederik Baraga. It is the originating station of Baraga's six station network airing local Catholic programming in addition to network programming from EWTN Global Catholic Radio and from Ave Maria Radio based at WDEO in Ypsilanti, Michigan. Its main office and studio is located at Indian River near The Cross in the Woods Catholic Shrine.
WTCK began as a construction permit issued by the FCC to Broadcasting For The Challenged Inc. in April of 2003. On May 15 of that year the call letters WWCZ were granted. In May of 2006,the new FM,after having its construction permit modified,began broadcasting Catholic programming. Later, in September Baraga Broadcasting purchased WWCZ from the original licensee..which was approved by the FCC in November of that same year.
WTCK programming is also heard in St. Ignace on simulcast station WIDG 940 AM (formerly a commercial station that had a variety of formats through the years) and on translator W236BZ 95.1 FM also in St. Ignace(formerly W237CF 95.3 in Mackinaw City), and in Gaylord on translator W221CA at 92.1 FM.
On October 22, 2011, another station was added to the Baraga Broadcasting family when WRQC at 91.3 FM in East Tawas returned to the air after a lengthy period of silence, prior to which the station had programmed a contemporary Christian music format under the ownership of Northern Christian Radio. WRQC has since changed its call letters to WGJU.
In July 2012, Baraga also began broadcasting on WGZR 89.1 FM in Alpena, at first licensed to All Saints School,then sold to Baraga in October of 2011 which was given FCC approval the following month of that year. 
A new logo and branding "Barago Radio" was introduced in the fall of 2014 with a new updated website: The Catholic Light dot com in addition to announcing that its offices will be moving to the Traverse City area .
