 The main KNCT signal barely covered Waco, while KAMU's signal just missed it.In 1989, it was upgraded to a full-fledged station, KCTF, which was spun off as a separate station in 1994 and ultimately taken over by Baylor University in 2000 as KWBU-TV.However, in July 2010, KWBU-TV began winding down operations and dropped all PBS programming prior to going off the air entirely on July 31 (it would later become KDYW, whose license was voluntarily canceled in 2012 following a failed attempt to sell the station to Daystar).
