Subchannels The signals of CPTV's stations are
multiplexed: WEDW is currently broadcasting 480i video on RF channel 21 with CPTV programming (49.1 virtual, 25% of packets). It shares its 6 MHz bandwidth with
WZME (43.1 virtual, 720p video, 32% of packets) and
MeTV+ programming (43.2 virtual, 480i video, 22% of packets). 21% of transport stream packets are null packets. Subchannels 49.2 and 49.3 are not currently broadcast by WEDW. As of 2023, WEDN currently broadcasts on
ATSC 3.0.
Analog-to-digital conversion in 2009, leading up to the
analog-to-digital television transition on June 12, CPTV shut down the analog transmitters of its stations on a staggered basis. Listed below are the dates each analog transmitter ceased operations as well as their post-transition channel allocations: • WEDH shut down its analog signal, over
UHF channel 24, on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 45, using
virtual channel 24. • WEDW shut down its analog signal, over UHF channel 49, on February 17, 2009, the original date on 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). The station's digital signal relocated from its pre-transition UHF channel 52, 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 UHF channel 49. • WEDN shut down its analog signal, over UHF channel 53, on June 12, 2009. The station's digital signal remained on its pre-transition
VHF channel 9, using virtual channel 53. • WEDY went off the air on July 31, 2005, as the result of equipment failure. Connecticut Public Broadcasting was granted permission by the
Federal Communications Commission to temporarily keep the station off the air until repairs were completed. CPBI also petitioned the FCC to allow WEDY's analog signal to remain off the air permanently, citing the need to use available funds on the construction of its digital facilities. The station's digital signal resumed on its pre-transition VHF channel 6 on June 13, 2009, using virtual channel 65. However, most New Haven viewers kept access to PBS programming due to the high penetration of cable and satellite in the area. On March 16, 2011, the FCC granted WEDY's petition to move from VHF channel 6 to UHF channel 41 because of viewer reception issues and interference from both
WPVI-TV in Philadelphia and
WRGB in
Schenectady, New York (both also operate on channel 6), after those two stations implemented recent power increases. ==CPBN Learning Lab==
