Radio First (Liggett Communications) is the owner of five radio stations in St. Clair and Sanilac Counties. Radio First primarily serves listeners in the Thumb area of Michigan and Southwestern Ontario. Radio First's offices and studios are all located at 808 Huron Avenue, Port Huron, Michigan. Prior to 2000, WHLS and WSAQ were owned by Wismer Broadcasting, while WPHM, WBTI, and WHYT were owned by Hanson Communications.
In early 2000, Liggett Broadcasting entered into an agreement with Hanson Communications to purchase WPHM, WBTI and WHYT (WHLX). Liggett also entered into another agreement to purchase Hanson's crosstown competitor, Wismer Broadcasting (whose owner and founder had died the previous year), licensee of WHLS and WSAQ. Liggett moved the operations of all five stations into Wismer Broadcasting's existing facility, as the building at 2379 Military Street did not have the office or parking space necessary to accommodate all of the stations.
