This week's crossword puzzle for March 5, 2023 sports an electronics theme. 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!
