We've developed a couple of infographics that help display the full history of Radio Scouting. The one show first was developed in late 2015. You can download the PDF file here: Radio Scouting V2015
It can be printed on 11 x 17 paper.
The Radio Scouting infographic shown below was originally developed for the 2012 Dayton Hamvention where it was displayed in the Icom America booth at the introduction of the BSA and Icom partnership. It's since been updated.
