July 1934 Radio News & Short-Wave

July 1934 Radio News and the Short-Wave 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.

Back in the early days of radio - and then later television - companies used big-name media personalities to promote their wares. To a lesser extent some of that happens today as well. Advertisements like this one for RCA's Radiotron vacuum tubes appearing in a 1934 issue of Radio News magazine is typical of what you would have seen in the era. In it, none other than Bing Crosby was joined by a trendily dressed woman who was rejoicing in her decision to buy a new radio that contained those newfangled "Micro-Sensitive" receiver tubes. Radio was considered a mystical entity by most people, and in 1934 there were still many households that did not yet host a radio of any sort. Rural residences often did not have AC service and relied on storage batteries to power machinery and appliances. Farmer Brown had to haul a wagon loaded with heavy lead-acid batteries to town to get them recharged. Some of the more prosperous ruralites had windmill- or water-driven generators to produce the necessary power. In fact, in 1934 a complete power generator setup could be purchased from the Sears, Roebuck catalog.

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...
