As we noted in our post Radio-active this season, there are many national Scout camps on the air this summer. One of those is K2BSA from the USA National Scout Jamboree in West Virginia. They will be on the air from 19 to 27 July.
You can see the frequencies, modes, and planned operations at Amateur Radio—Live From the Jamboree.
They also plan to launch an amateur radio high altitude balloon on 20 July. You can learn more about the launch and find links to track the balloon at Jamboree Balloon Tracking. Please note that the links presently shown on that page will not be active until the balloon launches.
