KDKA and Philadelphia's KYW are the only "K" call
letters for television stations east of the Mississippi
AFAIK (Pittsburgh does, I think, have KQV radio).
But there are still quite a few "W" calls west; besides
WOWT I can think of:
WHO and WOI Des Moines, IA
WIBW Topeka, KS
WDAF Kansas City, MO
WDAY Fargo, ND
WFAA Dallas/Ft. Worth
WOAI San Antonio
and Minneapolis is on the west side of the Mississippi,
but that's where WCCO is; Duluth has WDIO.
The original call letters dividing line was west of the Mississippi (100 deg. longitude, I think) and included Louisiana, Arkansas, Missouri, Iowa, and Minnesota, and most of North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas in the "W" section. When the line was moved to the Mississippi, existing stations were grandfathered in. In some cases, new "W" calls were allowed in the west and new "K" calls in the east if the TV station was co-owned with a radio station with grandfathered calls.
San Antonio's WOAI-TV used to be KMOL. Pittsburgh's KDKA-TV used to be WDTV back in its Dumont days.
Another "W" TV station licensed to a state west of the Mississippi is WDAZ Devils Lake ND.
Another "K" TV station licensed to a state east of the Mississippi is KBJR Superior WI.
If I'm not mistaken, because Minnesota and Louisiana lie on both sides of the Mississippi, stations in each state can use either "K" or "W". In those states, communities west of the Mississippi with "W" calls are WCCO, WUCW and WFTC, all licensed to Minneapolis MN. Communities east of the Mississippi with "K" calls are KTCA, KSTP and KTCI of St. Paul MN, KDLH and KQDS of Duluth MN, KRII of Chisholm MN and KGLA of Hammond LA.
