This custom RF Cafe electronics-themed crossword puzzle for February 19th
contains words and clues which pertain strictly to the subjects of electronics,
mechanics, power distribution, engineering, science, physics, astronomy,
chemistry, etc. 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. You might,
however, encounter the name of a movie star like
Hedy Lamarr
or a geographical location like
Tunguska,
Russia, for reasons which, if you don't already know, might surprise you. The technically inclined cruciverbalists amongst us will appreciate
the effort. Enjoy!
