Radio Boys was the title of three series of juvenile fiction books published by rival companies in the United States in the 1920s:
There was also a related Radio Girls series, another Stratemeyer Syndicate product, published by Cupples &amp; Leon and authored by "Margaret Penrose".
All of these series were launched seemingly simultaneously in 1922 and the earliest books in each series were by far the biggest sellers, often incorporating details on how to build a crystal set (a simple radio receiver). Later installments tended toward routine action adventure.
