The station signed on the air on November 11, 1946. As WMRP (Methodist Radio Parish) in the 1960s, it served as a broadcast ministry of the
United Methodist Church, featuring
MOR music with some
Christian talk and teaching shows. The conservative owners of WMRP-AM and
WMRP-FM 105.5 (unrelated to today's current
WMRP-LP at 104.7) refused to allow any cigarette or alcohol advertising on the stations. The United Methodist Church decided to sell WMRP-AM/FM in 1971, and the stations were purchased that year by John W. Nogaj, who converted 105.5 to
Top 40 and later
album rock as WWCK (the calls being a tribute to
CKLW in
Windsor, Ontario). The new owner installed a
country music format on AM 1570 with the new
call sign WCZN ("Your Country Cousin"). The country format was replaced by
oldies as "Solid Gold 16" in 1974. In 1975, following the sale of WWCK and WCZN to Reams Broadcasting, WWCK-FM went full-time album rock, and WCZN picked up the Top 40 format. This was followed by religious programming as WLQB (1976), a female-oriented talk/
adult contemporary format as WWMN (1981), and
beautiful music/
easy listening as WGMZ (picking up the calls and format that were dropped by 107.9 FM when it became
WCRZ in 1984). In 1986, AM 1570 became WWCK and began to simulcast WWCK-FM (which switched from
AOR to a
CHR format on January the 1st of 1989 following the sale of the stations from Reams Broadcasting to Majac of Michigan). Originally a daytime-only station on a Mexican clear channel, a treaty signed between the American and Mexican governments allowed the station to broadcast full-time at reduced power at night in 1986.
Cumulus Media took control of WWCK-AM/FM in March 2000, and a year later, WWCK dropped its simulcast of the FM station in favor of
urban contemporary gospel music via
ABC Radio's "Rejoice - Musical Soul Food" network. The Gospel format lasted four years. On March 1, 2004, WWCK switched to a
talk radio format. This allowed Flint to once again have a talk station of its own following
WFDF AM 910's move into the Detroit radio market as a
Radio Disney network affiliate. WWCK featured a roster of mainly
syndicated conservative talk show hosts including
Mark Levin,
John Batchelor and
Red Eye Radio. News, weather, sports, and traffic reports were provided by anchors from
WJRT-TV, state news from The Michigan News Network and national/international news from
Westwood One News. Weekend programs and hosts included
Kim Komando,
Joe Pags,
Bob Brinker,
Leo LaPorte,
USA Financial Headquarters,
Free Talk Live, and ''Mike Avery's Outdoor Magazine''. On January 1, 2021, WWCK changed its format from talk to
classic hits, branded as "K107.3". It also carries
Michigan State Spartans football and
men's basketball games. Cumulus Media suspended operations of the station and its FM translator on March 29, 2025. On March 5, 2026, WWCK and its translator resumed operation, with Cumulus submitting a resumption of operations letter to the
Federal Communications Commission on March 9, 2026. On March 30, 2026, Cumulus Media once again took WWCK and W297CG silent, 25 days after resuming operations. The latest Silent
Special Temporary Authority (STA) was filed on April 6, 2026. Mentioned in an attached file on the STA request Cumulus is in negotiations with a potential buyer of the station, no details were mentioned on who the buyer is. ==Previous logo==
