CQ is the magazine for active hams, with a focus on the practical. Every article is clearly written and aimed at involving you, the reader...whether it's a story of operating from some exotic location, an article to deepen your understanding of ham radio science and technology, or a fun-to-build project that will have practical use in your ham shack. Join us on our monthly journey through the broad and varied landscape of the world's most fascinating hobby!
