KSJX (1500 AM) is a radio station broadcasting a Vietnamese format. Licensed to San Jose, California, the station serves the San Francisco Bay Area. The station is currently owned by Multicultural Radio Broadcasting Licensee, LLC.[1]


AM 1500 signed on in 1948 with the call letters KXRX and 1,000 watts of power.[2] On September 7, 1982, KXRX became KHTT and later switched from a news format to middle of the road music.[3][4][5] KHTT began carrying Santa Clara University and San Jose State University men's basketball games in the 1985–86 season.[6][7] By 1986, KHTT switched to 1960s oldies.[8] In 1987, KHTT won the rights to live San Jose State football broadcasts; in the previous season, San Jose State football radio affiliate KCBS carried most games on tape delay due to conflicts with Stanford football games.[9]

On March 1, 1989, the station picked up its current call letters KSJX and a business news format.[10] Rival station KLIV picked up the rights to San Jose State football and men's basketball beginning in the 1991–92 season.[10][11] In 1992, KSJX began carrying Vietnamese programming.[12][13]

On October 9, 2010, a fire started in vegetation near the building where KSJX is based. It soon engulfed the radio station, destroying it, and also took out KZSF, a Mexican language radio station that is based at the same transmitter. The fire also caused the evacuation of a Kellogg's factory nearby.[14]
