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. We'll see how it goes.
The 2013 National Scout Jamboree operation of K2BSA from the Summit Bechtel Scout Reserve in West Virginia will provide QSL cards via online QSL request, direct to K5ND with SASE, via bureau automatically for overseas stations, and via Logbook of the World. You can verify your call is in the logbook here.
Here's a few QSL cards found in the National Scouting Museum archives. Send scans if you have some BSA QSL's and we'll post them here. Here's a very early one from the Boys' Life Radio Club.
For those engaged in an authorized K2BSA operation, we've provided two version of at QSL card that you can use to support your event. They are provided in a PDF four-up on an 8.5 x 11 sheet. The back side of the cards are blank for inserting your information. Print them on your color printer, cut them into four cards, print your information on the back, and you're good to go.
