Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Waaaay back in the mid-1980s when I first became aware of Digi−Key, it was one of the relatively few electronics component suppliers that had a large on-hand stock of commonly used parts and provided fast shipping. Places like Newark Electronics and Allied Electronics also provided good service, but Digi−Key usually offered lower prices than the others. By the 1990s, I was placing orders at least weekly during circuit design projects. Digi−Key was founded in 1972 in Thief River Falls, Minnesota - the town that for many years often had the country's lowest recorded daily temperature. This 1/4-page advertisement appeared near the back of a 1974 issue of Popular Electronics magazine. By the mid-1990s, their multipage ads in electronics magazines were proliferating like today's Harbor Freight ads. Here's a bit of trivia I just learned: The company's name is a reference to the "Digi−Keyer Kit," a digital electronic keyer kit that founder Ronald Stordahl developed and marketed to amateur radio enthusiasts.

If you are a Millennial or younger, the reference to a "Reader Service Card" at the bottom might be an enigma. It was a cardboard mail-in insert where you filled in circles next to companies from whom you wanted information mailed to you (which was more often than not ignored). They were sort of the pre-Internet version of a 2-D scan code.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
