JOTA-JOTI
Jamboree-on-the-Air is held the third weekend in October. A change in policy from previous years, there is no set time for the start or end. Since it isn’t a contest, there’s no designating starting point. When your station is ready to go, get on the air and make contacts. You'll have the whole weekend.
