WWKM is a non-commercial, Christian FM radio station licensed to serve Imlay City, Michigan. It is owned by Michigan Community Radio which is in turn owned by Jennifer and Edward Czelada. The station is part of their Smile FM network of Contemporary Christian music stations.
The station came on the air on December 18, 2000 with the callsign WHYT. It was the flagship of the Joy-FM network of stations planned by the Czeladas. In June 2004 the two networks owned by Jennifer and Edward Czelada, The Light and Joy-FM, were merged to form Smile FM.
In August 2004 the station switched call letters with its sister station on 88.1. The new WHYT remained in the Smile FM network while the older station switched to a traditional Christian music format and began calling itself Classic Christian Radio International.
In January 2008, WWKM switched to a Christian contemporary worship music format calling itself Smile FM Praise. WWKM was to be the flagship of the Smile FM Praise network. After the Smile FM Praise format was discontinued, the station switched back to the main Smile FM network in preparation for an increase in power and move to 88.9 from a tower near Oxford (see below).
The station had approval from the FCC to move its transmitter closer to Detroit and increase power to 6,000 watts. However, the construction permit expired on April 7, 2009. On August 26, 2009, WWKM was granted a construction permit for 6 kW on 88.9 from a different tower near Oxford. According to the station affiliate list on the Smile FM web site, WWKM will broadcast the main Smile FM network programming to the Rochester area and northern suburbs of Detroit. The coverage area will include portions of Oakland, Macomb, St. Clair, and Lapeer counties.
