The 1000-watt station covers much of the Mid-Ohio Valley, which includes parts of Southeastern Ohio and Northwestern West Virginia around the cities of Marietta and Parkersburg, West Virginia.

The station, upon receiving a Federal Communications Commission (FCC) license, relocated its broadcast studios to the basement of the historic Lafayette Hotel in downtown Marietta. The studios relocated again to the Citizen's Bank Building during the latter part of the 20th century before settling at their current location on Lancaster Street in Marietta.
