KWSU-TV's main signal serves a corner of the Spokane market as a "beta" station through the Program Differentiation Plan complementing KSPS-TV and Idaho Public Television.
The station is carried on the Spokane DirecTV and Dish Network feeds, expanding its potential audience to over 600,000 people in Washington, Idaho, Oregon and Montana.
KWSU-TV operates sister station KTNW (channel 31) in Richland, Washington, which serves as a full PBS member for the Tri-Cities area.
Although this station maintains its own studios on the WSU Tri-Cities campus in Richland, master control and most internal operations are based at KWSU-TV's facilities.
Collectively branded as Northwest Public Broadcasting, the two stations cover southeastern Washington and north central Idaho as well as Wallowa County, Oregon.
