KFPH-CD, Channel 35 in Phoenix, Arizona was granted a Special Temporary Authority by the FCC in early April to broadcast an experimental signal compliant with the current ATSC 3.0 interim digital transmission standard. The Unimas low power sister station of KTVW-DT will serve as “lighthouse” host to the subchannels of several other Phoenix TV stations, including KASW (Nexstar/CW), KPNX (TEGNA/NBC), KNXV (Scripps/ABC), KPHO (Meredith/CBS), KSAZ (Fox), KTAZ (NBC/Telemundo), KTVK (Meredith/independent), KTVW (Univision/UniMas), and KUTP (Fox/MyTV).

KFPH-CD proposes to adhere to the current FCC Report and Order that requires KFPH-CD to simulcast an ATSC 1.0 signal on its main KTVW-DT physical channel.

The experiment is being operated by the Pearl TV consortium run by several of the aforementioned participating owner groups “with a shared interest in exploring forward-looking broadcasting opportunities, including innovative ways of promoting local broadcast TV content and developing digital media and wireless platforms for the broadcast industry.”
