Electronics Theme Crossword Puzzle
October 8th, 2023

This custom RF Cafe electronics-themed crossword puzzle for October 8th contains only clues and terms associated with engineering, science, physical, astronomy, mathematics, chemistry, etc., which I have built up over more than two decades. Many new words and company names have been added that had not even been added to the world's technical lexicon when I started in the year 2002.

As always, this crossword contains no names of politicians, mountain ranges, exotic foods or plants, movie stars, or anything of the sort unless it/he/she is related to this puzzle's technology theme. You might, however, encounter the name of a movie star like Hedy Lamarr or a geographical location like Tunguska, Russia, for reasons which, if you don't already know, might surprise you.  The technically inclined cruciverbalists amongst us will appreciate the effort. A full list of all RF Cafe crosswords is at the page bottom. Enjoy!

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

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

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...
