At night, programming is largely from the Radio Fórmula talk network based in Mexico City.
KNRV is the Spanish-language flagship station for Colorado Rockies baseball and Denver Broncos football.
MacLee later sold the station to Western Broadcasting Corporation, owned by Corky Cartwright and Marvin Davis, in 1975.
[citation needed] In 1992, Radio Unica Communications bought the station in 1999 from Den-Mex LLC for $2.8 million.
The station went dark on July 27, 2004, due to the failure of KNRC's talk format.
