WPBS-TV (channel 16) is a PBS member television station in Watertown, New York, United States, owned by the St. Lawrence Valley Educational TV Council. The station's studios are located on Arsenal Street in Watertown, and its transmitter is located on St. Lawrence County Route 194 in Denmark, New York. WNPI-DT (channel 18) in Norwood operates as a full-time satellite of WPBS; this station's transmitter is located in South Colton, New York. WNPI covers areas of northeastern New York that receive a marginal to non-existent signal from WPBS, although there is significant overlap between the two stations' contours otherwise. WNPI is a straight simulcast of WPBS; on-air references to WNPI are limited to Federal Communications Commission (FCC)-mandated hourly station identifications during programming. Aside from the transmitter, WNPI does not maintain any physical presence locally in Norwood. The two stations combined have significant viewership in much of eastern Ontario, Canada, including Ottawa and Kingston; their slogan "Your Two-Nation Station" reflects this Canadian audience. History The St. Lawrence Valley Educational Television Council, which was organized in 1958, originally produced educational television programming to be carried by local CBS affiliate WWNY-TV (channel 7). In 1971, it established a free-standing PBS station, WNPE-TV, using WWNY's original studios on Champion Hill as the commercial station had already relocated to a larger facility in Watertown. Full-time satellite WNPI-TV signed on a few weeks later. Outgrowing the Champion Hill location itself, WNPE moved to a new building in Watertown in 1978. Because of its large Canadian viewership, WNPE was one of the more successful PBS stations, with fundraising totals often exceeding those of stations in much larger markets. For a minor sum, the rights to use the WPBS call letters were purchased from a small radio station in Conyers, Georgia in the late 1990s; the call sign change to WPBS-TV took effect on September 1, 1998. Following the shutdown of analog television signals, WPBS switched to a "-DT" suffix on July 2, 2009, as did WNPI; WPBS returned to the "-TV" suffix on March 11, 2020. Despite the calls, which mimic the callsign schemes used by stations owned by ABC, NBC and CBS in New York City and Los Angeles, WPBS-TV is not an owned-and-operated station (nor is similarly named KPBS in San Diego), as PBS cannot own or operate any of its member stations or regional member networks due to the network's local and non-profit nature; the
