What is "wcht"

WCHT (600 AM) is a radio station broadcasting a news/talk format. Licensed to Escanaba, Michigan, it first began broadcasting under the WLST call sign in 1958, and then became WBDN around 1971. WBDN programmed adult contemporary music throughout the 1970s and then went country around 1979, keeping that format until late 1986, when the station switched formats to oldies under the WCHT calls (with the call letters standing for Classic Hits).
