Dave offered: >There is still WRR (FM) City of Dallas commercial operation. Which was originally WRR from 1920, and KVP prior to 1920. ---------- 3-letter calls? How about KOA in Denver, KSL Salt Lake Ciy, KMJ Fresno. The KOB call is still in use at KOB-TV, though the AM call is now KKOB. At least they're not in Spanish! <g> Glen Kippel KHCS Palm Desert, CA
