Analog-to-digital conversion WNDU-TV discontinued regular programming on its analog signal, over UHF channel 16 on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 42, using PSIP to display the station's virtual channel as its former UHF analog channel 16. As part of the SAFER Act, WNDU-TV kept its analog signal on the air until March 3 at 7 p.m. to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
