Radio Reactions

December 2023

Ms. Marquis’s otherwise excellent summary of “Radio Grows Up” contains an error. The crystal radio sets of the early twenties didn’t use germanium; instead, it was galena, a much cheaper and more plentiful crystal, which then sold for twenty-five cents apiece. Ask any old-timer!

We hope you enjoy our work.
