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.

June 1931 Radio-Craft[Table of Contents]
People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Radio-Craft was published from 1929 through 1953. All copyrights are hereby acknowledged. See all articles from Radio-Craft.
June 1931 was a year and a half into the Great Depression, which began with the Wall Street crash of October 1929. It followed on the heels of the very prosperous decade known as the "Roaring Twenties," when significant, rapid advances in technology had taken place in electronics, medicine, physics, chemistry, and other fields. A huge number of radios were sold to the military, businesses, and private consumers both before stock market crash and after. A quick look at my list of Radio Service Data Sheets from the era show that to be so. In fact, it wasn't until World War II that production of new radio sets began to decrease, as all available resources were applied to winning the war rather than creature comforts. Back to 1931, though. Even with a severe downturn in the economy and unemployment skyrocketing, a few industries continued to provide relatively decent opportunities for skilled workers; electronics servicing was one of them. Although pay levels were not as good as before the Crash, at least there was work available to electronics technicians who were able to keep equipment functioning. This ad is typical of many placed by Coyne Electrical School in Radio-Craft and other trade magazines.
