There may be a few people out there who personally remember, but for those of you of younger generations, in the early 1900s there were a number of book series written for pre-teen and early teen children. Some of the more well known were the Bobbsey Twins, Hardy Boys, Tom Swift, and Biggles series.
In 1922, the first of another series appeared – The Radio Boys. Bob Layton, Joe Atwood, Jack Hampton, and other young amateur operators get involved in numerous adventures, all of which require the use of their homebrewed radios to rescue the victim, capture the criminals, or what have you.
A first time reader today would find these books somewhat odd, as compared to what passes for juvenile literature today. But in their day, each new title was eagerly awaited.
So, if you want a glimpse back into the early (and admittedly sometimes vaguely unbelievable) days of amateur radio, you could do worse than reading one or two of these books.
