History
KPER was founded by Don Bernard and Chuck Jobbins, co-owners of the Bernard & Jobbins Broadcasting Company.[4] After being granted a construction permit by the Federal Communications Commission (FCC) on January 23 that year, the station first broadcast on August 31, 1957, with call sign KPER and five watts of power.[5][6] The FCC officially granted KPER its broadcast license on November 21, 1957, and KPER increased its transmitting power to 500 watts and was licensed as a daytime-only station.[6] A member of the Keystone Broadcasting System, KPER also broadcast programming in Spanish and Portuguese.[4] KPER increased its power to 1,000 watts on January 21, 1959.[7] On May 2, 1963, KPER increased its power to 5,000 watts.[7]
On October 3, 1966, Bernard & Jobbins sold KPER to South Valley Broadcasters for $325,000.[8][9] KPER became KAZA on July 15, 1967.[6] By 1968, KAZA began broadcasting 85 hours of Spanish programming weekly, in contrast to seven hours of Portuguese.[9]
South Valley Broadcasters sold KAZA to Radio Fiesta on March 29, 1973, for $522,500.[10]
KAZA began carrying Spanish language broadcasts of Oakland Raiders games in 2002, the most recent season the Raiders made the Super Bowl.[11] The broadcasts continued for the 2003 season,[12] before they moved to KZSF in 2004.[13]
In November 2010, Tron Dinh Do's Intelli LLC began operating KAZA on a local marketing agreement with Radio Fiesta and began broadcasting the Vietnamese language Viên Thao Radio network. Radio Fiesta ultimately sold KAZA to Intelli for $1,000,000 in October 2014.[14]
