Still more:
WHB Kansas City MO, WDAY, Fargo ND, WCCO Minneapolis (west of the Mississippi), KSTP St Paul (east of the Mississippi) and many, many others in the Twin Cities, WACO Waco TX (no longer on AM but now an FM), I think WNAD Norman OK is gone but was replaced by WWLS. There are more W calls west of the Mississippi than K's east. The only three K's east of the Mississippi that I can think of have already been mentioned in this thread--KYW, KDKA, and KQV.
About 10 years ago, a station in Hew Hampshire, which was legally WKOS (930 in Rochester, I believe--now WGIN), identified as KOST--except at the TOH legal ID, when they also gave their CoL. At all other times, they referred to themselves as The Coast: K-O-S-T. Meanwhile, the REAL KOST was on FM in Los Angeles. Using another station's calls (at least those of a station on a different band) outside of the legal ID apparently doesn't violate FCC rules--and it got A LOT of attention for a short time. The station flipped format and calls in less than a year, however.
