Public Service

We normally assemble our list of events to serve, early in the year [Jan.-Feb.].

Updated: 12/11/2017
We assist local community-based non-profit organizations by providing volunteer radio communications for their events.
We welcome any interested licensed amateur to volunteer to assist us.  Let us know your available hours, and any preference of assignment when signing up for an event, and we will accommodate your schedule, if we can.
If you would like to request our club’s assistance for your event, please check our schedule below for conflicts, please read the Public Service FAQ, and download and submit the form found there. You may also wish to consult the Calendar of Public Events in the San Francisco Bay Area for dates for which volunteer Amateur Radio Service communication support has been requested.
Some worthy events are not served, either due to conflicting dates with other established commitments, or other amateur radio events,  a lack of available volunteer operators, because our small club does not have enough time to recruit volunteers, because our schedule is already full, because an event or the sponsoring organization does not fall within our established guidelines or FCC Rules for radio support; or because the event falls outside our repeaters’ reliable coverage area.  Our Board of Directors reserves the right to decline any request for communications support for any reason.
