10 meters and English
Almost all of the radio operators world wide speak English when on the air. In my opinion, it's because most foreign radio ops are professional people, doctors, dentists, engineers, probably educated in either the U.K. or the U.S. Also, most foreign schools make learning English a requirement for graduation.
