Jamboree on the Air is the largest Scouting event in the world. In a typical year over 1 million Scouts participate with over 11,000 stations operated by 20,000+ amateur radio operators in operation from 150+ countries around the world.
The National Radio Scouting Committee develops and maintains a great deal of JOTA supporting information online at Jamboree-on-the-Air in addition to all the information, station registration, and USA Reports posted on this site. You can see video reports of past year's activities below.
The official dates for 2015 are October 16, 17, 18. Note that JOTA officially begins on Friday evening at the start of the weekend.
