WGBX-TV, virtual channel 44 (UHF digital channel 43), is a non-commercial educational PBS member television station located in Boston, Massachusetts, United States. The station is owned by the WGBH Educational Foundation, and is a sister station to fellow Boston area PBS member station WGBH-TV (channel 2), Springfield, Massachusetts-based PBS station WGBY-TV (channel 57) and Boston area public radio stations WGBH (FM) and WCRB, and WCAI radio (and satellites WZAI and WNAN) on Cape Cod. WGBX's studios are located on Guest Street in Boston, and its transmitter is located in Needham, Massachusetts.
The X in its callsign stands for "Experimental", as WGBX (more primarily in the 1970s) was home to programming that was given a trial run on the lower-rated UHF signal before possibly moving onto the more-established WGBH-TV. Such Eastern Educational Network imports from the United Kingdom as Doctor Who were seen first or more frequently on WGBX, and one late 1970s local "nightclub"-style variety show, Club 44, proved popular enough to be moved over to WGBH and retitled The Club. The station airs PBS programs that are not aired by WGBH-TV as well as additional supplemental programming. Reruns of the previous night's programming either from WGBH-TV or from WGBX-TV itself also makes up part of channel 44's programming schedule. WGBX also carries the digital subchannels owned by the WGBH Educational Foundation; this enables WGBH to maintain a full 1080i high definition picture resolution on its main channel 2 signal, without any loss in visual quality.
