Electronics Theme Crossword Puzzle
October 15th, 2023

This week's crossword puzzle for October 15th sports an electronics theme. This being the 15th day of the month, many of the words begin and/or end with the letter "O." Clues for words containing "O" are marked with an asterisk (*). All RF Cafe crossword puzzles are custom made by me, Kirt Blattenberger, and 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!

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

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...
