KHJ (AM)
KHJ is an AM radio station licensed to Los Angeles, California and broadcasting at 930 kHz. Owned and operated by Immaculate Heart Radio, through licensee IHR Educational Broadcasting, the station broadcasts religious Catholic programming as an affiliate of their regional radio network.
KHJ was a Top 40 station from 1965 to 1980. KHJ switched to country music in 1980 and back to pop music in 1983. In 1986 the station adopted an oldies format as KRTH. Two years later the station was sold to Liberman Broadcasting and a format of regional Mexican music aired from 1990 to November 2014. KHJ is triplexed to three of the six towers of KBLA (1580 kHz), near the intersection of Sunset Boulevard and Alvarado Street in Los Angeles. Radio station KYPA (1230 kHz) also uses two of KBLA's towers for its signal. The KHJ towers at the intersection of Venice and Fairfax Avenue were removed in February 2013.
History
1920s and 1930s
KHJ went on the air at 720 AM on April 13, 1922. It later moved to 760 AM in response to increased interference on the AM band. The Federal Radio Commission (FRC) regulated the band in 1927-28 and reassigned KHJ to the regional-service frequency of 900 kc. with 1000 watts of power, where it remained until 1941. At that point, a reorganization of the AM band by the Federal Communications Commission (successor to the FRC) in conjunction with the North American Radio Broadcasting Agreement raised KHJ's power to 5,000 watts and moved to 930 kc. (where it continues to operate).
