Radio Amateurs Guide to the Ionosphere
Radio Amateurs Guide to the Ionosphere
by Leo F. McNamara
Edition: Paperback
Price: 37.50

5.0 out of 5 stars The key to more contacts, 9 Nov 2009
This book contains a massive amount of information for the serious radio amateur concerning propagation. It is well written and concise, however there are a number of sections which were too deep for me, as I have no plans to do mathematical modeling before going 'on air'.

Nonetheless, if you are serious about learning more, this is a great book that will deepen the knowledge of any radio amateur. Even skipping those sections that are not relevant for your particular situation or needs you will still learn a tremendous amount about how the atmosphere affects radio waves and how you can improve your chances for better and long distance contacts.

5.0 out of 5 stars A subject worth a lot more attention, 9 Nov 2009
For those who followed Lars Brownworth's podcast, this book will not come as a total surprise as is builds upon that series with additional information. However, it is more than just a repeat performance with greater details, material, facts and a deeper sense of context, in particular concerning the Muslim invasions.

Things that happened less than 1,500 years ago are clearly still affecting us today in a most extreme fashion; Lars' new book will asisst anyone who values history in grasping a sense of the historical background that tragically propels certain cultures today. When you see all the mistakes present day decision makers who never opened a history book make by repeating the same mistakes as others did 1,500 years ago, this book becomes highly relevant in ways one might not at first imagine....

If you want to learn more about this period of history and get a compact overview of its most salient events, this book is the perfect starting point, and it is filled with suggestions for further research if you feel so inclined. Heartily recommended!
