Based on what I know though all of the TV Guides and newspaper archives, KSCH Channel 58 (now KQCA) in Sacramento, CA aired NBC's Saturday Morning lineup because it's NBC affiliate KCRA 3 pre-emepted it for a Saturday Morning local newscast, and WPXI 11 in Pittsburgh also pre-empted it for a Saturday local newscast in 1990 but I don't know if WPGH 53 or WPTT 22 aired NBC's Saturday Morning lineup. So do you guys know of any other Fox or Independent station that aired the ABC, NBC, or CBS Saturday Morning lineup?
