January 1940 Radio News

January 1940 Radio News
January 1940 Radio News Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

Judging by some of the letters written to magazines by their readers, obtaining parts referenced in many construction articles proved difficult or impossible to procure. Ziff-Davis, a major publisher in 1940 as well as today, ran this notice in a 1940 issue of its Radio News magazine offering advice as to how one might go about getting everything needed. Unlike nowadays where nearly every available source worldwide can be found on the World Wide Web, back then searching could be - and too often was - a long, slow process. Just finding a phone number or mailing address for a potential supplier presented a major obstacle to anyone without a collection of catalogs and magazines - or at least knowing someone who did. Imagine needing ten non-standard parts and having to write letters to manufacturers and/or distributors trying to located critical components. The back-and-forth with postal mail could require weeks or even months. One notable omission from the list is to contact a local amateur radio club for assistance, where there is a chance one of the member might have the part you want, or at lease know of a good way to find it - possibly via wireless communications.
