WBGH-CD
WBGH-CD is the Class A, NBC- affiliated television station for the Eastern Twin Tiers of Southern Upstate New York and Northern Pennsylvania. Licensed to Binghamton, it broadcasts a low-powered digital signal on UHF channel 20 from a transmitter at its studios on Ingraham Hill Road southwest of downtown. The station can also be seen on Time Warner Cable channel 5 (hence the NBC 5 branding) and in full high definition on digital channel 1203.
Owned by the Nexstar Broadcasting Group, WBGH is sister to ABC affiliate WIVT and the two outlets share studios. It can be seen in 720p high definition over-the-air on its own signal and on the second digital subchannel (UHF channel 34.2) of full power WIVT from the same tower.
