This custom made Electronics theme crossword puzzle for January 1st is provided
compliments of RF Cafe. A special message is included (marked with 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 puzzle 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!
