QST is a magazine for amateur radio enthusiasts, published by the American Radio Relay League (ARRL). It is a membership journal that is included with membership in the ARRL. The publisher claims that circulation of QST in the United States is higher than all other amateur radio-related publications in the United States combined
The name of the magazine is derived from the radio Q signal that means "calling all stations". The magazine was first published in December, 1915, and has been continuously published since May, 1919.
Publication of QST was temporarily suspended after the September 1917 issue. In April 1917, the United States government, following its entrance into World War I, banned all amateur radio activities, and a large percentage of the magazine's subscribers had entered military service. The ban on amateur radio was lifted after the conclusion of the war. QST returned in May 1919 with no cover - billed as "ARRL Special Bulletin" - and only 8 pages long. Publication continued throughout World War II, despite amateur radio's hiatus by order of the U.S. government. During both wars, amateurs were in high demand as military radio operators, and QST's staff pitched in for the war effort.
