The Jamboree on the Air is an annual event in which half a million Scouts and Guides all over the world make contact with each other by means of amateur radio. Short-wave radio signals carry their voices to virtually any corner of the world. The use of amateur radio means that many Scouts get the opportunity to discover the skills of wireless radio techniques and electronics. JOTA is also the only event that offers each individual Scout the opportunity to speak to other Scouts across the world. In 2019 JOTA took place place from 18 to 20 October 2019. Jamboree on the Internet connects Scouts across the world using the internet. ScoutLink Active Support Unit and volunteer organisations like Scoutnet provide the necessary technical support and server capacity. In 2019, JOTI took place from from 18 to 20 October.
