The Jamboree on the Air (or JOTA) is an annual event that allows around 500,000 members of the Scout Movement Worldwide to communicate using amateur radio.

JOTA has taken place ever since 1958 and now takes place over the third full weekend in October every year. Although the event officially starts at 0000 hours on Saturday, and finishes 48 hours later at 2359 hours on the Sunday, there is often traffic before (and after) because of variations in timezone.

Although the event is available for the whole weekend, local circumstances will govern when people actually join in; there is no need to take part for the whole period.

More information is available in Factsheet (FS120521) "Jamboree on the Air", available from the Information Centre.
