 WJMN-TV discontinued regular programming on its analog signal, over VHF channel 3, at around 1 a.m. (occurring within a commercial break during "The Late Late Show with Craig Ferguson") on February 17, 2009, the original 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).The station's digital signal remained on its pre-transition UHF channel 48, using PSIP to display the station's virtual channel as its former VHF analog channel 3.As part of the SAFER Act, WJMN kept its analog signal on the air until March 3 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.
