"Ham Radio Magazine" was a periodical that ran for almost 22 years from 1968 to 1990. Use this indexed search to quickly find what you'd like to look at and then go purchase the scanned magazines (On CD, elsewhere, or occasionally from some generous download website) or look for the old paper magazine at used bookstores.
