Crystal Sets to SidebandI am 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. 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. I strongly urge you to take a read and share with potential hams.
