Analog-to-digital conversion
WPXK-TV shut down its analog signal, over UHF channel 54, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 23. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 54, which was among the high band UHF channels that were removed from broadcasting use as a result of the transition.
