WHBF-TV shut down its analog signal, over VHF channel 4, at 6:01 a.m. 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 relocated from its pre-transition UHF channel 58, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 4. WHBF-TV is now one of the very few TV stations in the United States to broadcast its digital signal on a low VHF channel assignment, alongside former sister station WOI-DT in Des Moines and ABC O&O station WPVI in Philadelphia.
