Earth Radio also dumped their eclectic rock format in September 1979 in favor of disco.
Program Director Dennis Newhall was let go and took the same position at KROY-FM under Operations Manager Richard W. Irwin (who has an interesting radio history site at www.reelradio.com). Several other staff members were let go as the station dropped the "Earth Radio" name and took on the identity of "FM 102" while retaining the KSFM call letters. The format followed the pop charts, which had become flooded with dance hits. The new regime, consulted by Jerry Clifton, delivered ratings that not only put FM 102 ahead of KROY and all other top 40 competitors within a year, but also among the top stations in the market for years to come.
FM 102 prevailed in a lawsuit with KWOD over supposed slanderous remarks about KWOD made in 1989 on air by Chris Collins. His last day on FM 102 was November 5, 1991 after twelve
years at the station. In 1992 Collins filed a huge wrongful termination suit against KSFM, claiming drug abuse among management personnel,
which he did not conform to, but the parties ended up settling out of court. Collins briefly did a talk show on KSTE (650 AM) but later became a
sports commentator for the San Jose Sharks on KFRC then CEO of Digicast Corporation in Seattle.
