Radio Themed Crossword Puzzle
October 4th, 2020

October 4th's custom Radio themed crossword puzzle contains only only words from my custom-created lexicon related to engineering, science, mathematics, chemistry, physics, astronomy, etc. (1,000s of them). You will never find among the words names of politicians, mountain ranges, exotic foods or plants, movie stars, or anything of the sort. You might, however, find someone or something in the otherwise excluded list directly related to this puzzle's technology theme, such as Hedy Lamarr or the Bikini Atoll, respectively. The technically inclined cruciverbalists amongst us will appreciate the effort.

cruciverbalist: [noun]  cruci- ("cross") +‎ verbal ("words") +‎ -ist ("agent, person") -- A person who constructs crosswords.

Reproduction of this puzzle without the express permission of RF Cafe is prohibited.

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
