History
Knoxville Family Television, Limited Partnership, was granted a construction permit on November 3, 1982, to build a station on Knoxville's channel 43; the proposal from Knoxville Family beat out another by Marvin E. Palmquist, who owned WQRF-TV in his hometown of Rockford, Illinois.[1] Channel 43 had previously been used for several years by WBIR-TV as a UHF relay to aid areas in the city of Knoxville that did not receive a satisfactory picture on VHF and was discontinued upon an upgrade to the VHF facility.[2]
