73 Magazine

73 Magazine (also known as 73 Amateur Radio Today) was a United States-based amateur radio magazine that was published from 1960 to 2003. It was known for its strong emphasis on technical articles and for the lengthy editorials in each issue by its founder and publisher, Wayne Green. According to the ARRL Letter, "73 was a pioneer promoter of SSB, FM, solid-state, easy construction projects, and the marriage of personal computing and amateur radio." After completing 43 years of publication, 73 Amateur Radio Today magazine ceased publication with the September 2003 issue.

The articles high-lighted for each issue are basically construction articles and do not relect the entire contents, including tech discussions, editorials, columns and reader letteers.
