National Radio Institute Home Study Course

National Radio Institute (NRI) Advertisement 1926 - RF Cafe

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.

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

About RF Cafe Copyright: 1996 - 2024 Webmaster: Kirt Blattenberger, BSEE - KB3UON 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...
