The station shut down its analog signal, over VHF channel 4, on June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal remained on its transition period UHF channel 35, using PSIP to display KDFW's virtual channel as 4 on digital television receivers.
