ham radio

On this day in 1925 during a congress in Paris held by a consortium of national organisations representing hobbyists and enthusiasts, the International Amateur Radio Union was formed. Its mission, continuing to the present, is to safeguard a frequency spectrum reserved for the purposes of non-commercial exchange, experimentation, training, recreation and contests and competitions, including radio direction finding, a type of geocaching, and speed telegraphy using Morse-code—“ham” originally a gently pejorative term for operators with poor sending accuracy, being somewhat ham-fisted.
