What is ARRL Field Day?

ARRL Field Day is amateur radio’s largest annual operating event. Each year, radio operators across North America set up temporary stations to practice emergency communications, demonstrate amateur radio to the public, and enjoy a weekend of learning, operating, and fellowship. 

What You'll Experience

Field Day offers something for everyone. Whether you're a licensed amateur radio operator or simply curious about the hobby, you'll find hands-on activities, demonstrations, and a welcoming community.
