License swap
Because it was granted an original construction permit after the FCC finalized the DTV allotment plan on April 21, 1997 [4], the station did not receive a companion channel for a digital television station. Instead, on or before February 17, 2009, which is the end of the digital TV conversion period for full-service stations, KTAZ will be required to turn off its analog signal and turn on its digital signal (called a "flash-cut").
