Mount Diablo
Amateur Radio 


The Mount Diablo Amateur Radio Club (MDARC) was founded in 1946. 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 good will within our community, and have fun in the process.               


Our Mission

MDARC provides a wide variety of programs and activities for its members. These include hosting and staffing PACIFICON (ARRL Pacific Division convention) each October, bringing in great speakers and offering ham radio classes to the public.  Our annual picnic, holiday party and radio equipment auction are all enjoyable events!
