Japanese QRP Book (1)


Prominent QRP books are introduced in this blog. The first one is 'QRP Handbook' published in 1996. More than 30 QRPers contributed. Articles are divided into three section as operation, homeblew equipment and antennas. Thus the position of this book is similar to 'QRP POWER' of ARRL. This book is already out of print and sometimes found in auction at double price.
