Jamboree-on-the-Air Kurz (JOTA) is an event of the international scout movement and will be held on the 3rd weekend in October. With the help of amateur radio stations, connections between the individual scout groups are established. The radio stations make it possible for scout groups to speak, write or even exchange pictures with one another across borders and continents. These contacts often lead to friendships that last for a long time. Shortwave radio links are mostly used. This enables contacts over great distances, even worldwide. The term "Jamboree" comes from English and describes a large camp of boy scouts.
The event has been held annually since 1957. In 2017, 1.5 million scouts from 160 countries took part in the event, making it the largest scout event worldwide. The event starts on Friday evening and ends on Sunday afternoon.
