KSJX (1500 AM) is a broadcast radio station licensed to San Jose, California, United States. Owned by Multicultural Broadcasting, the station broadcasts programming in Vietnamese. Founded in 1948 with the call signs KXRX, the station had various music formats in its early decades. The station was locally owned for most of its first 50 years of operation except 1978 to 1991. In the 1970s, KXRX expanded its programming to include news. From 1972 to 1980 and 1987 to 1991, the station was the radio home for San Jose State University sports. After an ownership change, KXRX became KHTT in 1982 and changed its music playlist from middle of the road to current hits. In 1986, KHTT switched to oldies.
