American Radio Relay League (ARRL) is the national association for Amateur Radio in the United States; and with more than 161,000 members, it is the largest organization of radio amateurs (“Hams”) in the world.  ARRL's mission is based on five pillars:  Public Service, Advocacy, Education, Technology, and Membership.  By design, Amateur Radio has always been an open-source type environment with much of its equipment, tools, and technology being self-built and freely shared (by Hams).  

Once again, the ARRL has authorized a "Special Events" station to operate at the Southern California Linux Expo 2017 (SCaLE-15x) under the temporary call-sign of "N6S".  In addition to demonstrating various aspects of radio communication, the station will highlight the synergistic relationship between Amateur Radio and the open-source community.  SCaLE-15x participants are invited to come, see, listen to, ask about, and even operate!
