December 1947 Radio & Television News Cover - RF Cafe[Table of Contents]  These articles are scanned and OCRed from old editions of the Radio & Television News magazine. Here is a list of the Radio & Television News articles I have already posted. All copyrights are hereby acknowledged.

Farnsworth model EC-260 (radiomuseum.org) - RF CafeFarnsworth model EC-260 (SAMS Photofact) - RF CafeMagazines usually provided at least a brief description on the circuit functionality for each of the radio models presented in schematic format.

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...
