After at least twenty years of coordinating broadcasting auxiliary frequencies below 1 GHz, John Barcroft is passing on those duties to Gary Stigall. Fred Swift of KUSI coordinates channels above 1 GHz.
Those wishing to submit frequency coordination requests should use the form posted on the SBE 36 Coordination Page. There are links posted there for NFL and Southern California Frequency Coordination Committee that handles coordination outside of San Diego County.
Barcroft was KGB (FM) and KPQP (AM) Chief Engineer for decades before leaving in 2006 and was quite active in the SBE during his radio career. He and Ron Foo produced the SBE Chapter 36 newsletter until 1997.
