This week's crossword puzzle for September 24th sports an electronics theme.
This being the twenty−fourth day of the month, many of the words begin and/or end
with and/or contain the letter "X" (denoted by an asterisk). Expect a few repeats, since words with and "X"
in them are harder to come by. 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!
