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).

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).

WWCK featured a roster of mainly syndicated conservative talk show hosts including Mark Levin, John Batchelor and Red Eye Radio.

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.
