Retrofit kits for adding shortwave bands to commercial broadcast band radios were a big deal back in the 1930s. Magazines like Radio-Craft were full of articles and advertisements for such kits. Few layman radio owners were capable of installing the conversion kits, so radio service shops took in a lot of business installing them. A large percentage of radio models soon thereafter began shipping with the shortwave bands incorporated into the base unit - known as 'all-wave' radios. This Majestic Model 11 Short-Wave Converter is a prime example of the kits. My 1941 Crosley Model 03CB vacuum tube console radio has shortwave bands, as does my 1970s vintage Magnavox 789 transistorized radio.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

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...
