sentences:  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 withdrew support for 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) and installed a country music format on AM 1570 with the new calls WCZN ("Your Country Cousin").The country format was replaced by oldies as "Solid Gold 16" in 1974.
