Here is RF Cafe's electronics-themed crossword puzzle for January 28th. 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!
