810AM first went on the air in 1948, as KCMO-AM moved to the frequency for a 10-fold boost of its previous 5k-watt day/1k-watt night signal at 1480AM.  Five years later Tom Evans & Lester Cox sold the station to Meredith Corporation, who maintained the full service format for ten more years.  In 1963, KCMO became a Middle of the Road outlet, eventually seguing to an innovative mix of MOR and country music dubbed "Mod Country."  In 1981, the station adopted a news/talk format, which survived a procession of new owners in the 80s and 90s, and moved to 710AM in 1997 as part of a frequency swap with then-country WHB-AM.  Two years later, fledgling Union Broadcasting would purchase WHB in order to launch a 24-hour home for the sports programming that had been aired on daytime-only Sportsradio 1510 KCTE.
