The FM translator originally started broadcasting on and off beginning in the summer of 2014 from the Radio First studios in Downtown Port Huron with 250 watts. After the switch from "The Cruise" (which never branded itself as being on FM) to "Rock 105.5" (which only brands itself as being on FM), a construction permit was granted to WHLS to move the translator to their parent station's tower on 32nd Street in Port Huron Township. The station currently broadcasts with only 49 watts but from a much higher tower and covers the immediate Port Huron, Fort Gratiot, and Marysville areas.
