We are a unit of trained professionals who supply communications assistance to the agencies of the City and County of San Francisco on an ongoing basis, but particularly in times of disaster. Our goal is to support the gathering and distribution of information necessary to respond to and recover from a disaster. Our standard method of communication is amateur radio (ham radio), but we also use telephone, internet, text messaging, Twitter and public service radio frequencies.

Volunteers are primarily licensed Amateur Radio operators; individuals possessing other technical and communications skills and licenses are also welcome to apply. Training in basic emergency communications is provided, as well as in-depth training and exercises to familiarize personnel with the many City agencies we serve.


The ACS Leadership Team is comprised of the following:

Lawrence Lin AB2PS

Deputy Chief
Corey Siegel KJ6LDJ

External Stations Lead
Bob Peterson KG6QDK

Membership Lead
Cathy Peterson KG6QDJK

Facilities Lead
Tom Wenger KJ6TGS

Training Lead
Peter McElmury AA6SF
