in high definition, starting with its weekday noon broadcast, with the introduction of a new set and weather center. KDKA was the last major Pittsburgh television station to begin airing newscasts in HD and the WPCW shows were included in the upgrade. Technical information Subchannels The station's digital signal is multiplexed: Analog-to-digital conversion WPCW shut down its analog signal, over UHF channel 19, 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 moved its digital signal from its pre-transition UHF channel 49 (where its digital signal was originally slated to remain post-transition) to VHF channel 11 (the former allocation of WPXI's analog signal). Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 19. Interference with Cleveland CBS affiliate WOIO that existed when both stations operated analog signals is no longer an issue as that station is broadcasting its digital signal on VHF channel 10. In July 2009, the station applied with the FCC for a repeater digital signal on channel 27 in Johnstown. Translator WPCW was previously relayed on WBPA-LP in Pittsburgh (owned by Venture Technologies Group) from the days when it did not have a strong signal throughout the city.
