Just downloaded and have started reading through the 400 plus pages of Frank K0IYE’s work:

Crystal Sets to Sideband

The Four State QRP Group is very pleased to offer the latest version of Crystal Sets To Sideband by Frank W. Harris, KØIYE. This book has become an icon within the QRP community as an excellent treatise on the homebrewing science/art. When first released in 2002 Mr. Harris donated his work to amateur radio. He provided these Version 12 pdf files to Four State on 21 Jan 2011, they are free and are posted here with his permission. Frank is a retired engineer and an excellent author. His easy to read style makes this not only a fine and informative reference book, but also a very pleasant reading experience.. Click on the links below to download and save each chapter. Enjoy this great book with our best wishes, it’s a FB read.
