After a few short stints at other stations, Edwards was hired at KMPC in Los Angeles, occupying the 9 a.m.-noon slot for several years beginning in February 1968 until December 1979 when he resigned to focus on his TV career. He later worked at KFI from 1987 to 1989 but he ultimately resigned, as a protest against fellow KFI personality Tom Leykis, destroying Cat Stevens' (Yusuf Islam) records following Stevens' call for a fatwa on Salman Rushdie. Most recently, Edwards was a morning DJ with KSUR (now KKGO) in Los Angeles. One of the features of his radio show was "Radio's Answer Lady," in which listeners could call in with questions — some serious, some not so serious — and he would answer on the air, sometimes with serious answers, sometimes with quips.
