Amateur radio has consistently been the most reliable means of communications when other systems have failed. Hams work closely with disaster relief agency officials from FEMA, the American Red Cross, the Salvation Army, and other response organizations to offer wireless communications aid. From wildfires and earthquakes to marathons and road races, when getting the message through is critical, ham radio works. This book is for all hams who volunteer their time and skill to serve their communities. It provides knowledge needed for communicating quickly and effectively during disasters, emergencies, and community events, as well as an opportunity for learning more about the Amateur Radio Service and its unique role in supporting the public.
