The station first signed on April 7, 1974 as KZIQ. Originally owned by Space/Time Broadcasting Company, it aired a country music format.[4] In June 1986, Space/Time sold KZIQ and its FM sister station KZIQ-FM to Bel Air Broadcasting Corporation, owned by Robert M. Rosenthal, for $335,000.[5]
Bel Air attempted to sell KZIQ-AM-FM in 1991, but the first two deals fell through. The first deal reached was in January with Michaels Media, headed by Pat Michaels, for $650,000.[6] In March, a sale to Blessing Broadcasting valued at $682,500 also failed to close.[7] By the end of the year, Bel Air successfully sold the combo to James Knudsen for $250,000 — less than half of either previous deal. At the time, KZIQ aired an oldies/classic rock format.[8]
On May 21, 2001, KZIQ changed its call letters to KWDJ. In May 2006, KWDJ flipped from country music to talk radio as "Fox Radio 1360". Featured talk shows included The Rush Limbaugh Show, The Glenn Beck Radio Program, The John Gibson Show, and The Alan Colmes Show. The station aired Fox Sports Radio programming on weekends.[9]
In January 2013, James and Donna Knudsen sold KWDJ and KZIQ-FM to Adelman Broadcasting for $220,000. The deal included a time brokerage agreement allowing Adelman to begin programming the station immediately; the sale closed in April.[10][11] Until early 2014, KWDJ aired a sports format as a Fox Sports Radio affiliate.
In 2016, the station became a radio affiliate of the Los Angeles Rams of the National Football League.[12]
