Field Day 2024 is the weekend of June 22-23. CARS is currently planning this event.
From the American Radio Relay League (ARRL) :
Field Day is ham radio’s open house. Every June, more than 40,000 hams throughout North America set up temporary transmitting stations in public places to demonstrate ham radio’s science, skill and service to our communities and our nation. It combines public service, emergency preparedness, community outreach, and technical skills all in a single event. Field Day has been an annual event since 1933, and remains the most popular event in ham radio.
