Mount Diablo
Amateur Radio Club


The Mount Diablo Amateur Radio Club (MDARC) was founded in 1947. Today it has a membership of over 300 dedicated hams and is one of the largest amateur radio clubs in California. MDARC's purpose is to encourage innovation in amateur radio, provide public service and educational opportunities, foster goodwill within our community, and have fun in the process.               




COVID-19 Note:
02/12/2021
Our Club is aware that vaccines are becoming available and we encourage  our members to take advantage of the opportunity to receive these. We encourage members and guests to continue following the health order requirements from the various Counties by wearing face coverings, washing our hands, and abiding by in-person restrictions based on the County tier.

Until we receive the “All Clear” from the County for meeting in person, we will continue holding meetings using Zoom which we have found to be very effective for conduction Club business and continuing camaraderie.

Take advantage of the many Nets on our W6CX repeater. 

As we all work through these times, please bookmark these websites and for more information .
