I came across a helpful free online book by Frank Harris, K0IYE,
Crystals Sets To Sideband, A Guide to Building an Amateur Radio Station.
This book offers a great introduction into the world of home brewing with a simple easy to read format. I especially like his idea of picking up an ARRL Amateur Radio Handbook from the 1980's for the more do able projects. The newer editions have tougher projects that I have passed up on. The book link is listed below.
Frank's station is also 100% home brewed!
A very nice read!!
