WNDT-CD, (channel 14) is a class A low–power, First Nations Experience-affiliated television station, licensed to New York, New York. Owned by The WNET Group (formerly known as the Educational Broadcasting Corporation and later as WNET.org), it is sister to the city's two PBS member stations—Newark, New Jersey-licensed WNET (channel 13) and Garden City, New York-licensed WLIW (channel 21)—and Class A station WMBQ-CD (channel 46). Under a channel sharing arrangement, WNDT-CD and WMBQ-CD share transmitter facilities with WNET at One World Trade Center. Despite WNDT-CD and WMBQ-CD legally holding low-power class A licenses, they transmit using WNET's full-power spectrum. This ensures complete reception across the New York City television market. In addition to FNX programming, WNDT-CD airs some news and public affairs shows from WNET and NJ PBS. History W73AP and W17AC (1973–1992) The station was signed on over UHF channel 73 in 1973 by its original owner, WPIX, Inc., as W73AP. It was one of multiple television broadcast translators in New York City that operated at the upper end of the UHF television band in order to provide reliable coverage to sections of New York City where reception was compromised by the construction of the World Trade Center. It relayed WPIX, which operates over VHF channel 11. Originally, most of the New York City television stations operated their main transmitters from the Empire State Building. However, reliable reception was compromised for some viewers once the majority of the World Trade Center was constructed, thus necessitating the use of the UHF translators. In response, nearly all of the TV stations, including WPIX, relocated to the North Tower of the World Trade Center in 1975. In 1982, UHF channels 70 through 83 were decommissioned for use as television stations, and the frequencies were reassigned for the Advanced Mobile Phone System (AMPS), an analog mobile phone system standard developed by Bell Labs that was officially introduced in the Americas in 1983. TV stations operating on these channels were either displaced to in-core broadcast channels, sold, or deleted. WPIX filed for displacement around this time, and the station's translator was reallocated to channel 17 with the new alpha-numeric call sign W17AC, reflecting the station's new channel number. The station continued to operate as a relay for WPIX. More than a year after WPIX became a Tribune Broadcasting station outright in 1991 and expanded coverage in New York City, New Jersey and Long Island over
