Electronics Theme Crossword Puzzle - Final for 2023!
December 31st, 2023

This week's crossword puzzle for December 31st sports an electronics theme. Hard to believe it is the final crossword for 2023! This being the 31st day of the month, many of the words begin and/or end with the letter "E." Since there are only 26 letters in the alphabet, I use the modulo function to derive the letter to use; i.e., 31 mod 26 = 5. Clues for words containing "E" are marked with an asterisk (*). Related clues are marked with an asterisk (*). All RF Cafe crossword puzzles are custom made by me, Kirt Blattenberger, and have only words and clues related to RF, microwave, and mm-wave engineering, optics, mathematics, chemistry, physics, and other technical subjects. 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 (e.g., Reginald Denny, Hedy Lamarr, or the Tunguska event in Siberia). The technically inclined cruciverbalists amongst us will appreciate the effort. Enjoy!

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