73 Magazine is another great resource on all brands of vintage radio gear and the history of radio. Articles cover a wide range of subjects. The magazine ceased publication with the September 2003 issue. There are no sources for purchasing back issues. This means that hamfests, eBay, etc. are probably the best (or only) places to find issues. What follows is a chronological listing of Eico related articles gleaned from the 73 Magazine Index created by Steve KB9MWR.
