 Jerry
Rappel (WWØE), current VP of the Eastern Iowa DX Association
(EIDXA) and newsletter editor, contacted me about using one of the weekly engineering-themed crossword puzzles in the group's newsletter. I
responded by offering to create a custom crossword for them. The result is this week's puzzle. Clues for words specific to EIDXA have asterisks
(*) after them. All the rest of the words are related to engineering and science.
