National Radio Institute Home Study Course

RF Cafe University "Factoids," "Kirt's Cogitations," and "Tech Topics Smorgasbord" are all manifestations of my ranting on various subjects relevant (usually) to the overall RF Cafe theme. All may be accessed on these pages:

Old Ad for National Radio Institute: 'I Will Train You at Home!' - RF Cafe Website

Bob Davis sent me a link to Mike Yancey's (KM5Z) website where there is a scanned version of the 1948 National Radio Institute (NRI) home study course for radio technicians. It is a very extensive collection of 55 volumes (PDF format) covering topics like Simple Radio Circuits and Meters, Radio Coils and How They Work, How Detectors Work in Radio and Television Receivers, Current, Voltage and Resistance Measurements, and How to Eliminate Man-Made Interference. KM5Z also has some other good content that you might be interested in while you're there like a 1958 edition the RCA Radio & TV Course, online calculators for toroids, inductor Q, voltage dividers, and antenna field strength, and radio restoration projects.

NRI ran full-page advertisements in many electronics and mechanics magazines from the 1940s through the 1980s; e.g., Popular Science, Popular Mechanics and Radio News. I am a proud graduate of the National Radio Institute's "Electronic Design Technology" course, circa 1987.
