Gonna have to do more research to find it. I was part way thru the course. He had a pic on the webpage and the guy at the start talked about how it was often used in scouting.
All he did basically in each lesson was throw in a new series of letters, then you copied them as he gave the code etc...There were probably 30+ lessons. I found it pretty good but they were definetly old because he used the old style phonetics.
