While looking at the Services Edition of the 1979 Television Factbook, which includes what local stations were carried on almost every CATV system in the country at this time, I noticed that there were quite a few stations that covered at least parts of a handful of states.
Some examples include:
WBBJ (7) Jackson, TN (AL, AR, KY, MO, MS, TN) [6 states]
WLOS (13) Asheville, NC (GA, KY, NC, SC, TN, VA) [6 states]
WGAL (8) Lancaster, PA (DE, MD, PA, VA, WV) [5 states]
WFSB (3) Hartford, CT (CT, MA, NH, NY, RI, VT) [6 states]
KELO (11) Sioux Falls, SD/KDLO (3) Florence, SD/KPLO (6) Reliance, SD (IA, MN, ND, NE, SD) [5 states]
KOTA (3) Rapid City, SD/KDUH (4) Hay Springs, NE/KHSD (11) Lead, SD (CO, MT, ND, NE, SD, WY) [6 states]
The Salt Lake City stations were carried as far away as Williston, North Dakota
