In late 1967, KHJ in Los Angeles offered Tuna the 9 to noon slot, where he debuted on Thanksgiving Day 1967. On February 9, 1971, he had just commenced his morning show at 6:00 a.m. when the San Fernando earthquake occurred. In early 1972 he did mornings at KCBQ in San Diego (during the original presentation of "The Last Contest") and later that year became one of the original DJs at KROQ AM, a new Top 40 station (formerly Country KBBQ). In 1973 he moved to KKDJ as program director and morning personality. He presided over its 1975 call-letter change to KIIS, and broadcast the first show at KIIS-FM as it began its AM/FM simulcast. He also worked at KTNQ, KHTZ (later KBZT), KRLA, KODJ (later KCBS-FM), KMPC, KIKF, and KLAC.
