May 1958 Radio & TV News Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

If you happen to be a retired television repairman from the era of analog broadcast and cathode ray tube (CRT) displays, or if you have studiously read the many articles I have posted from vintage electronics magazines about TV, then you will probably breeze right through this themed crossword puzzle from a 1958 issue of Radio & TV News. I have to admit to having done poorly myself, even after having been the one who posted all that stuff. Just having a general knowledge of electronics doesn't help much here since all the clues and words are very specific to television circuits. Still, it's worth the challenge and if nothing else you'll learn a little more about old time television- it really was a quite ingenious scheme for cramming a lot of information into a relatively small bandwidth, especially for color TV.

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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
