ATSC 3.0 is Coming to Rochester, NY

On March 23, 2023 at 10 am, Rochester, NY’s first ever ATSC 3.0 signal will be on the air. Using Sinclair’s WUHF, Rochester will have ATSC 3.0 versions of its CBS, ABC, PBS, and FOX affiliates. In order to make this happen, channels that are currently on WUHF’s existing ATSC 1.0 signal will be added to various stations broadcasting on Pinnacle Hill. WUHF’s Fox Rochester will become a subchannel of Nexstar’s WROC-TV, Antenna TV and Comet TV will become subchannels of Sinclair’s WHAM-TV, and TBD will become a subchannel of WXXI’s WXXI-TV. Essentially, for having a broadcaster’s channel on the ATSC 3.0 signal, the agreement is the respective broadcaster will add a former WUHF subchannel to their station. This way, WUHF’s programming stays on the air in ATSC 1.0, and in return, these other broadcasters get their main channel on an ATSC 3.0 signal, in addition to their own ATSC 1.0 signals. The current ATSC 1.0 Rochester signals I receive in Niagara County, NY suffer from multipath fading, a phenomenon that plagues ATSC 1.0 signals. ATSC 3.0 fixes this by using OFDM for modulation. OFDM uses a guard interval, and has significant symbol multipath tolerance, compared to almost none from ATSC 1.0’s 8VSB modulation.
