For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has a theme related to
engineering, mathematics, chemistry, physics, and other technical words. This one has extra words pertaining to radar
and radio. You will never be asked the name of a movie star
unless he/she was involved in a technical endeavor (e.g., Hedy Lamarr). Enjoy!

 Take 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.
