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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

May 1963 Electronics WorldTable of Contents
People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Electronics World was published from May 1959 through December 1971. See all Electronics World articles.
Nearly every week I create and publish a crossword puzzle filled with words and clues all of which are relevant to the realms of engineering, science, mathematics, chemistry, mechanics, optics, communications, amateur radio, etc. It is rare to find a crossword puzzle that contains no 'filler' type words used just for the sake of being able to construct a puzzle. I use software that takes my custom-built dictionary of a few thousand words and definitions, and fits them to grids that I create. Probably an hour is spent every Sunday making the RF Cafe Crossword Puzzles, and I really don't know how many people even bother with them. This "Electronic Crosswords" puzzle appeared in the May 1963 issue of Electronics World. While it does have a large percentage of technical words, there are still a large number of fill words as well.
