On June 26, 2006, KOTV-DT2 was converted into a standard definition simulcast feed of Muskogee-based WB affiliate KWBT, in order to relay that station's signal to portions of northeastern Oklahoma located north of a line from Salina to Drumright that—because the channel 19 transmitter is located in rural northwestern Muskogee County, in compliance with FCC regulations that prohibit broadcast transmitters from being located more than 25 miles from the station's city of license—could not adequately receive the KWBT signal.
