Amateur Radio Theme Crossword Puzzle
May 8th,
2022
|
|
This May 8th custom made crossword puzzle has an Amateur Radio (aka Ham Radio)
theme, compliments of RF Cafe. Clues specifically related to the Ham Radio
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 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!

RF Cafe is prohibited.
