United Models 980744, 980745 SAMS Photofact, January 1947 Radio News - RF CafeUnited Models 980744, 980745 Buick 'Sonomatic,' January 1947 Radio News - RF CafeMagazines usually provided at least a brief description on the circuit functionality for each of the radio models presented in schematic format. The January 1947 issue of Radio News published schematics and parts lists for six sets, including this for the United models 980744 and 980745 "Sonomatic," but not a word about any of them accompanied it - just the schematic and PL.

Radio Service Data Sheets

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...
