Every year, on the fourth weekend of June, amateur radio operators from across North America gather for ARRL Field Day—the largest and most recognized event in the world of amateur radio communications. Held continuously since 1933, the event combines emergency preparedness exercises, technical education, operating competition, and public outreach. This year's edition will take place on June 27–28, when thousands of radio amateurs will once again set up temporary stations in parks, campgrounds, and other outdoor locations to test their skills and readiness to provide communications during emergencies.
Field Day is an annual amateur radio exercise and contest organized by national member societies of the International Amateur Radio Union (IARU). In the United States, it is the largest volunteer-led emergency communications exercise, with more than 30,000 operators participating each year. The primary goal of the event is to evaluate the ability to rapidly deploy independent radio communication systems when conventional telecommunications infrastructure is damaged or unavailable.
Since the first Field Day in 1933, amateur radio operators have practiced building and operating stations away from their permanent locations—from simple tent setups in parks and forests to sophisticated installations at Emergency Operations Centers (EOCs). The use of alternative power sources such as batteries, generators, and solar energy is strongly encouraged, as electrical power and other public infrastructure are often among the first services to fail during natural disasters and severe weather events.
During the 24-hour operating period, participants strive to make as many contacts as possible using a variety of frequency bands and operating modes. While the competitive aspect helps evaluate operator skills and equipment effectiveness, the educational and community-building components are equally important. Additional points are awarded for activities such as experimenting with unique operating modes, making contacts through amateur radio satellites, conducting public demonstrations, and actively involving youth in amateur radio.
Field Day is much more than a contest. For many clubs, it is an opportunity to camp together, host radio demonstrations, enjoy family activities, and showcase the capabilities of modern amateur radio to the public. The event demonstrates that amateur radio operators continue to play an important role in emergency communications while also fostering a vibrant community of technology enthusiasts, educators, and public-service volunteers. Once again, Field Day 2026 will provide an opportunity to test operating skills, promote technical education, and strengthen relationships among amateur radio operators across the country.
