Here is your custom made Filter-themed crossword puzzle for April 3rd, 2022.
Clues for words relevant to the theme 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 or the
Tunguska
event in Siberia). The technically inclined cruciverbalists amongst us will appreciate
the effort. Enjoy!
