Exploring the Magic of Wireless Communication
There are countless ways for radio signals to travel from transmitter to receiver, and understanding how radio waves interact with their environment is an important factor in successful radio communications. While amateurs can maximize station performance and reliability with the right equipment, knowledge and skill, we cannot control propagation. Through scientific exploration and experimentation, we can improve our understanding of propagation and how it affects radio signals.
Propagation and Radio Science presents a comprehensive overview of one of the most fascinating and rewarding activities in Amateur Radio. Author Eric Nichols, KL7AJ, uses his lively, engaging approach to present the complex subject of radio propagation in simple, easy-to-understand terms. This book covers topics ranging from theoretical exploration to practical application. It explains the phenomena we observe on the amateur bands and invites you to embark on the journey through the still-unknown radio propagation universe.

About ARRL Founded in 1914 by Hiram Percy Maxim, ARRL (American Radio Relay League) is the national association for Amateur Radio in the US. Today, with more than 161,000 members, ARRL is the largest organization of radio amateurs in the world. ARRL's mission is based on five pillars Public Service, Advocacy, Education, Technology, and Membership.

At first I did not take this book seriously. The author uses waaay too many puns and spends too much time developing analogies for simple concepts that are clear enough already. But after a while, I learned to ignore this stuff and found there is really quote a lot of meat here.The book starts with very basic particle physics, optics and refraction with a focus for how these topics control and modify passing EM waves. It then applies these to the rarified plasma that makes up the ionosphere. Also covered is the effects of ground on propagation and goes into how this all relates to antenna performance. Finally, I think the last few chapters are the best, where the book discusses questions that are still open and potential areas of further research.
So if you don't get distracted, this book has lots of good info and ideas for experimentation.

Propagation and Radio Science First ARRL Inc Reviews
As being new to radio operations this has all the valuable information
Item as described, arrived in good condition. Thank you.
Extremely informative yet easy to read. I am am new HAM and this is such technical topic that it's easy to get lost. However this book breaks the concepts and topics down very well. I recommend this book to anyone trying to learn more about propagation for their HAM radio hobby.
A most welcome book on propagation. Very good explanation on how propagation work without being to complex or using high math. covers the mechanism behind the propagation of radio waves and the being of the radio-waves them self.
Also covers different modulations and there behavior under certain propagation conditions and when to use what.
A good book for the more interested HAM or radio addict who wants to know how things work in the 'ether'. A good start to explore more.
The writer understands the art of wakening the taste for more.

This title provides the amateur radio enthusiast with a macro and micro view or wave propagation. At times, this text is dry and contains some filler content to review past material but the text is full of great material and explanation of propagation, the ionosphere and how to instructions. Highly recommended and worth your money.
This is an excellent book. It is written in an informal style (appropriate to its intended Radio Amateur "Ham" audience), Although lacking in a formal academic style, the text is clear and easy to read. I found no technical errors and found the book to be easy to read, although for a non professional reader, there are sections which the reader will want to read several times over.
The scope of the book is surprisingly wide, covering a broad topic with delightful completeness. Whether a reader is interested in completeness or in a quick review of radio wave propagation science, this book should satisfy.
There is much more to the science of world wide radio signal propagation than a casual observer might suspect, and this book does an excellent job.
This reviewer was one of the original designers of the "Topside Sounder", the first satellite ionosounder to probe the upper side of the ionosphere, and is proud to have made a contribution to ionospheric physics; this book brought back many vivid memories, some of them sad because they relate to friends and coworkers who are no longer with us ...
I got interested in the DX hobby, and intend to extend to Amateur Radio and Amateur Astronomy. Based on that I bought some books and this was one of them. If your interest is in any of the three topics above or are curious in this aspect physics, you will not regret buying this book. Reasons are
1 - Language - The author has the skill of depicting technical topics in a very easy to understand and informal way, nevertheless I finished the book with a clear picture of the processes involved.
2 - Crescendo - I like the style of starting with something we are familiar (light) and then building on that to explain the other topics. This requires a bit of understanding in physics, particularly polarization. You will need that concept, but chances are that if you heard of that, you did it for light in whatever physics classes you took.
3 - Coverage - I figured out that radio propagation is a vast field. The author tackles many concepts in a concise way, but it provides links on concepts you want to expand.
On the improvement side, I think some graphs need to be a bit bigger, like the Ionograms (I bought the kindle version of the book), but then jump on Google and you will get the graphs and axis you need to read.
Overall great reading. Good job.
