American Radio Relay League
Founded in 1914 by citizen radio operators who wanted to pass messages over the air, the American Radio Relay League (ARRL) is currently the largest organization of radio amateurs in the United States. Their stated goal is to: "promote and advance the art, science, and enjoyment of Amateur Radio".
Beginning in December 1915, the league began publishing a monthly journal called QST. Except for a brief period during the Great War, their journal has been published continuously.
