of educational, New England and local programming to a schedule nearly identical to that of WGBX-TV), and master control operations were relocated to the WGBH studios in Boston. Following the changes, Comcast dropped WGBH and WGBX from its New Hampshire systems and NHPTV from its Massachusetts systems. Stations As of the DTV transition on February 17, 2009, the NHPBS stations were: Notes: 1. WENH did not use the -TV suffix in its callsign during its construction permit until April 17, 1959. Subchannels The digital signals of the NHPBS stations are multiplexed: Analog-to-digital conversion NHPTV's stations shut down their analog signals on February 17, 2009, the original date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). Each station's post-transition digital allocations are as follows: WEKW-TV shut down its analog signal, over UHF channel 52; the station's digital signal remained on its pre-transition UHF channel 49. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 52. WENH-TV shut down its analog signal, over VHF channel 11; the station's digital signal relocated from its pre-transition UHF channel 57, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 11. WLED-TV shut down its analog signal, over UHF channel 49; the station's digital signal remained on its pre-transition UHF channel 48. Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 49. Translators Notes: 1. Successor to W18BO, which operated on analog channel 18 in Pittsburg. From 2005 until November 4, 2009, W26CQ was owned by Hearst Television and served as a translator for ABC affiliate WMTW. The license for W26CQ was cancelled by the Federal Communications Commission on October 5, 2016. 2. The Federal Communications Commission (FCC) considers W34DQ-D to be the same station as the former W18BO. It went on the air on September 27, 2010 and is currently operated in addition to W26CQ. 3. Formerly W15BK, which operated on analog channel 15 (it flash-cut to digital on September 4, 2007). All three translators directly repeat WENH. Colebrook and Pittsburg are part of the Portland market, while Hanover is part of the Burlington–Plattsburgh market. In addition,
