Traffic passing by formal relay (via amateur radio) originates from the founding of the American Radio Relay League. The NTS as it exists today was first outlined by George Hart, W1NJM (died 24 March 2013) in “New National Traffic Plan: ARRL Maps New Traffic Organization for All Amateurs” as part of the September 1949 issue of QST. While traffic passing between amateur radio operators was nothing new, Hart’s system extended coverage of traffic capability in a uniform manner across the U.S. and Canada, creating formal section and area nets devoted to handling NTS-organized traffic.
