on march 23, 1972, lake huron broadcasting sold the station to rust craft broadcasting, who changed the call letters to the current weyi-tv. soon afterward, the station moved to its current tower and studios on west willard road in vienna township. the new tower significantly improved channel 25's coverage in flint while still being within of saginaw as required by federal communications commission (fcc) regulations. prior to 1972, the southern side of the flint/saginaw/bay city market, including flint itself, got a better signal from lansing's wjim-tv (now wlns-tv). rust craft merged with magazine publisher ziff-davis in 1979. the wknx callsign is currently being used by an independent station in knoxville, tennessee.
