WHYT is a non-commercial, contemporary Christian FM radio station licensed to serve Goodland Township and Imlay City, Michigan. The transmitter is located between Imlay City and Marlette, Michigan. The station broadcasts on 88.1 with .4 kW and is owned by Superior Communications (aka Michigan Community Radio and Northland Community Broadcasters) which is owned by Jennifer and Edward Czelada.
WHYT began broadcasting in October 2003 as Joy FM with the callsign WWKM. In June 2004 it merged with the other The Light and Joy FM stations owned by Superior Communications to form Smile FM and took the WHYT callsign from its sister station on 89.1 which switched to a different format. Programming with local inserts originates from WLGH in Lansing.
WHYT was granted a Construction Permit on March 24, 2009, to increase power to 12.5 kW.
Smile FM Internet streaming originates from WHYT and includes the WHYT/WTAC/WCZE ID at the top of each hour.
The WHYT call letters were first used at a small market daytime AM station in Noblesville, Indiana (now silent and defunct),then used for many years by 96.3 Detroit (now WDVD) and were also used by what is now WHLX in Marine City after 96.3 FM dropped the calls. The call letters WTAC were used by AM 600 in Flint when it was a popular top 40 station during the 1960s and 1970s, and subsequently through country and contemporary Christian formats. That station is now WSNL. WCZE is based on the first three letters of the owners' last name.
