Here is your custom made Electronics Themed crossword puzzle for December 4th,
2022. The four newly minted numerical prefixes are included and are indicated with
an asterisk (*). The prefixes were declared in 2022 by the
General Conference on Weights and Measures in Versailles, France. All RF Cafe
crossword puzzles are custom made by me, Kirt Blattenberger, and have only words
and clues related to electronics, electricity, radio, radar, 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 or the
Tunguska
event in Siberia). The technically inclined cruciverbalists amongst us will appreciate
the effort. Enjoy!
