About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

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

Engineering Crossword Puzzle
December 28, 2014

This is the final engineering crossword puzzle of 2014, that is to say the 52nd of the year. I have created more than 500 crossword puzzles, each using a custom-built library of words and clues specific to engineering, science, mathematics, etc. - no numbnut celebrity names, clothing articles, or mountains on the continent of Africa. Thanks, fellow cruciverbalists, for another year of participation. Don't forget to print out an extra copy to leave in the John for your fellow indisposed workmate to pass time with.

Visit the Crossword Express website - RF CafeTake a well-deserved break and try your hand at some of these goodies. Every word in the RF Cafe crossword puzzles is specifically related to engineering, mathematics, and science. There are no generic backfill words like many other puzzles give you, so you'll never see a clue asking for the name of a movie star or a mountain on the Russia-China border.

All of these crossword puzzles were created using the fabulous Crossword Express (now called "Magnum Opus") software.
