History

The station started as WSDC in 1951, then WDOG and later became WSMA with country music.

Early years

WHLX went on the air on December 10, 1951 with the call letters WSDC, operating from its transmitter facility at 5300 Marine City Highway, on the outskirts of Marine City. Doing business as Radio St. Clair, Inc., Jerry Coughlin served as the station's first president and general manager.

By 1954, Coughlin had turned the duties of general manager to sales director John Bell and renamed the station WDOG. Fred Cale assumed sales and management duties by 1960.

First sale

In February 1967, Coughlin sold WDOG to Sommerville Broadcasting Company, owned by Richard S. Sommerville. He renamed the station WSMA, and adopted a country music format. It maintained this format and call sign for the next 26 years.
