2019 Public Service Events (be sure to check back for updates and additions)

Beginning in early spring each year and continuing into early winter many ham radio operators from the Mt. Diablo Amateur Radio Club become involved in doing radio team communications to support various public service events that occur nearby. The events include long distance bike rides, bike races, running races, walkathons, a March for Babies, a half marathon, a Mt Diablo Trail Ride, and local city parades.

The locations include beautiful scenic areas such as nearby regional and wilderness areas, Mt.Diablo State Park, and municipal trails and parks. Some of the agencies and causes that we have helped are: Children's Hospital of Oakland, the MS Society, the March of Dimes, Meals on Wheels, and Save Mt. Diablo.

Contact the MDARC Public Service Coordinator, Klaus Berkner K6KHB, to sign up for events.
Call 925-370-1865(h), 510-610-1865 (c), or email  khberkner@comcast.net

Participating in these events is a thrilling experience for many different reasons. These include:

  • The magic of radio transmissions

  • The camaraderie of being part of a radio team that helps make things safer for hundreds, sometimes thousands of event participants

  • The chance to do something meaningful for a good cause

  • The fun and satisfaction of using your radio equipment and opportunity to learn its various capabilities in real-life situations

  • The beautiful places and settings that you get to enjoy

Radio operators are assigned to check points, or to support (SAG) vehicles, or are on bikes, or sometimes in boats. Radio communications in some of these areas can be a challenge, but very gratifying and a whole lot of fun! For most events all you need is a 2 meter hand-held radio with an extra battery. When you participate, consider bringing a family member or friend to show them the excitement of the ham radio hobby.

This is a fun way to get out and use your radio, help a worthwhile cause and gain valuable experience that will come in handy in the event of a major emergency or disaster. It's also great PR for the club and amateur radio in general.
