KDKA wasn't the only exception.

Indeed, there's another K-station in Pittsburgh, KQV. Some other
examples include KFIZ in Fond du Lac, Wis. and KTGG in Spring Arbor,
Mich.. (the latter only a few years old; reportedly a FCC clerk thought
"MI" stood for "Missouri") There was a WPXJ-TV in Minden, Louisiana
(near Shreveport) for awhile, but when the error was caught it got
changed to KPXJ.

I can't think of any W-stations in the West, unless you count those
located between the old and new dividing lines that were compliant the
old way but aren't now.
