IC-7850/IC-7851 Technical Reference Books

1 Customer Reviews

The IC-7850/IC-7851 Technical Reference Book is a comprehensive resource regarding the IC-7850/IC-7851. As well as giving precise technical information, it illustrates practical know-how and points for successful operation based-on actual user situations. This book is also interesting reading material if you are an IC-7850/IC-7851 owner or even just an HF enthusiast. The over-title of this book is "The Art of Radio Communication," which is ICOM's attitude toward radio design.

These 132 pages are the ultimate source of information for the "How" and "Why" of the world's ultimate transceiver. The information contained within its covers goes beyond the owner's manual to explain and educate. ICOM explains how they approach the creation of leading-edge radio equipment and why it is an art… something beyond the technical ability required.

Whether you own an IC-7850/51 or not, this book is a fascinating insight on ICOM's attitude and reasoning behind communications radio development.
