SC4ARES Membership

ARES® volunteers are prepared to assist in public service events, emergencies and disasters. The first requirement of membership is that they must hold a current amateur radio license and indicate their willingness to serve by registering with their local Emergency Coordinator. ARES members are given a task book in which they track and document their training plan elements as they are completed toward levels of increasing proficiency. Membership in ARRL or a local radio club is not a requirement for ARES membership.


In addition to ARRL standardized training basic level 1 requirements, SC4ARES requires completion of the FEMA IS-100 course (or equivalent) and periodic participation in radio net and training exercises to demonstrate and maintain proficiency. If you are interested, visit our registration page.
