RF Cafe Engineering & Science Crossword Puzzle
July 14, 2019

Unlike all of the other engineering and science-themed crossword puzzles I have ever seen, every word and clue - without exception - in these RF Cafe puzzles has been personally entered into a very large database of relevant terms. The list has been built over nearly two decades of creating these crossword puzzles. Let me know if you would like a custom crossword puzzle built for your company, school, club, etc. (no charge). The same software, Crossword Express, has been used to generate the puzzle for all those years - made by the good guy at AUS-PC-SOFT (in Australia) that wrote the program. Read down near the bottom of the linked page and you will see where he was doomed by people distributing his software without paying for it (I paid for mine). I suffer the same injustice from people who receive my RF Stencils for Visio and RF Cascade Workbook software without paying me for my hard work. You might be surprised at how widely my stuff has been pirated. It doesn't provide much of an incentive to create new versions.

cruciverbalist: [noun]  cruci- ("cross") +‎ verbal ("words") +‎ -ist ("agent, person") -- A person who constructs or works crosswords.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...
