Amateur Radio - Ham Radio Magazine Searchable Index - List by Category

A Searchable Index of the old "Ham Radio" Magazine

"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.

If you use the Internet Archive frequently, consider making a small donation for their continued great work - or at least for the bandwidth.
