Amateur Radio Club
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.
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!

Membership in MDARC includes autopatch access to all three MDARC voice repeaters (W6CX). We also maintain an ATV repeater, and support Packet / APS EchoLink, and IRLP. The W6CX D-STAR repeater is operational and connected to our gateway on the Internet.
