Amateur Radio Crossword Puzzle
January 25, 2015

This is likely the last engineering-themed crossword puzzle that I will be creating. It takes about an hour to make and publish each one, and since I suspect the number of dedicated cruciverbalists out there are few, it is just not worth the effort anymore. Without any memorable exceptions, I have created a crossword puzzle every week since sometime in the year 2000 (more than 700 total). Each one was made with personally selected words to avoid non-relevant terms and clues. The puzzles will resume if enough requests come in to do so, otherwise, today marks the end of an era.

I will still be glad to create a special edition crossword for your newspaper, newsletter, etc.

Visit the Crossword Express website - RF CafeTake a break from the drudgery by trying 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.
