The Auxiliary Communications Service is a program created by government to supplement its emergency communications with professional, unpaid volunteer staff. ACS is not an amateur radio club. It is part of local government and operates under the authority of the Sonoma County Fire and Emergency Services Department.
ACS supports any and all government public service communications systems in the event of failure, overload or other problems that might jeopardize their usefulness. The volunteers provide emergency communications between the county and its jurisdictions, county and city governments and neighboring county governments.
ACS may provide communications support using amateur radio, cellular and regular phones, computers, e-mail, facsimile, internet, microwave, public service radio (police, fire, law enforcement), satellite, television, and video-conference systems; as well as field and in-office support of personnel, in order to maintain the highest possible level of staff and equipment readiness.
