On April 2, 2009, WCPX officially began broadcasting Ion Television programming in high definition (available in the 720p resolution format). Analog-to-digital conversion WCPX-TV shut down its analog signal, over UHF channel 38, 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 continued to broadcast on its pre-transition UHF channel 43. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 38 (which, in its physical form, is now occupied by the post-transition digital signal of Univision owned-and-operated station WGBO-DT, virtual channel 66). The "WCPX" callsign was also transferred from the former analog channel 38 to digital channel 43, and the "WCPX-DT" callsign was discontinued; the callsign was modified to "WCPX-TV" on June 15.
