KDKB-FM's rock format was simulcast on 1510 KDKB (AM). In 1978, the AM simulcast was broken and 1510 changed formats to oldies. The AM call letters were changed to KDJQ ("The Golden Rock") with program director Robert M. Chenault and morning DJ Griffin Gary "Toad Hall" Kinsey, followed later by Bruce "Brother" Baumbush. In 1980, the format on KDJQ changed to new wave music for a brief time, with Jonathan "Johnny D." Dixon as the program director and Jonathan L as assistant program director, music director, and evening personality. 1510 is now broadcasting a Financial/Business News format as KFNN. KDKB was the first Album Oriented Rock (AOR) station in the Phoenix media market, and one of the first AOR stations in America.
