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...

RF Cafe Website Categories Crossword Puzzle
October 18, 2015

OK, I admit that this week's crossword puzzle is a little self-serving and self-promoting, but what the hey. All of the clues with an asterisk (*) after them are categories in the table of contents at the tops of RF Cafe website pages, so that should help a bit. To make it even easier, they are all on the 'Main' TOC menu. All the rest of the words, as usual, are related to engineering, science, mathematics, etc.


Reproduction of this puzzle without the express permission of RF Cafe is prohibited.

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
