R-E Puzzler
March 1967 Radio-Electronics

March 1967 Radio-Electronics

March 1967 Radio-Electronics Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Electronics, published 1930-1988. All copyrights hereby acknowledged.

These R-E Puzzlers look like a typical crossword puzzle, but they are not. The only "crossword" aspect is a single letter being shared by two words. There are no words formed vertically, only horizontally. That makes them a little more difficult because if you don't know one of the words, there is no way to discover any additional letters in it other than the one given. This particular R-E Puzzler appeared in a 1967 issue of Radio-Electronics (hence the R-E part), so it is no surprise that there are a couple vacuum tube related words. It should present no problem if you know common numerical prefixes and append "ode" to the end. Have fun.

If you like this R−E Puzzler, there are other in the Jan '67, Mar '67, Apr '67, Aug '67, and Oct '67 issues.

A cruciverbalist is a person who is skilled at creating or solving crossword puzzles. The term is a combination of "cruci-" from "crucifix," meaning cross, and "verbalist" from "verbal," indicating a person who deals with words. cruciverbalists are often responsible for designing crossword puzzles, and they possess a deep knowledge of wordplay, vocabulary, and the techniques used in constructing and solving crosswords. They aim to make puzzles that are both challenging and enjoyable for crossword enthusiasts.
