QSL paths for K2BSA can be a bit trying since most operations are conducted by others who have used the call sign in support of a Scouting event. Effective July 2011, all approved K2BSA operations also have submitted their QSL contact information. That information is posted on the QSL Paths page.
Also, effective January 2012, K2BSA established a Logbook of the World account and is uploading all ADIF logbook files that are forwarded from the K2BSA operating events. Of course, the operator must log all the contacts and then forward the file for this to work.
K2BSA Jamboree logbooks for 2013 and 2017 are available on Logbook of the World and on ClubLog. The NA1WJ World Scout Jamboree logbook is also available on those services.
Here are a few QSL cards found in the National Scouting Museum archives as well as a few recent ones.
Here’s a very early one from the Boys’ Life Radio Club.
