KDAY 1580

US radio station from Los Angeles, California, on 1580 AM. Active under this name from 1948 to 1991. Later resurrected as kday (2004-?). KDAY first signed on in 1948 as a 10,000-watt soul/R&B outlet at 1580 AM. After his firing from WABC in November 1959, famed disc jockey Alan Freed arrived at KDAY. In 1983 KDAY fought back by hiring Greg Mack from KMJQ in Houston as music director. Mack eventually added hip hop music to the station's playlist to appeal to mostly young Black and Latino listeners. Dr. Dre and DJ Yella became the first mixer DJs at the station. In 1990, Mack left KDAY. Real estate investor Fred Sands, bought KDAY the next year, and on March 28, 1991, at 1 p.m., KDAY switched to a business format with call letters KBLA.
