Jerryre Jackson KE5VZH just discovered a set of books published in the 1930s called, The Radio Boys. The “Radio Boys” first books were about the boys meeting a man who helps them build their first receiver and their adventures with that. The first five are available free on Kindle. Here is a LINK to the first one in the series. Thanks Jerryre for providing the information!
Just for Fun
