5.0 étoiles sur 5 One of the two best ways to prepare for your Extra Exam 4 juillet 2012
Par The Travel Insider - Publié sur Amazon.com
Format: Broché Achat vérifié
First, a quick check - as you probably know, the question pool for the Extra exam changed on 1 July 2012. Make sure that you get the matching edition of this book and CD - if you order from this page you will be getting the correct edition - the tenth edition. The ninth or earlier editions are useless now.

This new tenth edition corrects the shortcomings and problems in the ninth edition which I'd earlier commented negatively about, and uses the same layout and logic as is present in the current version of the General exam study manual too.

I've found the best way to study is to use the CD/computer questions/review together with the printed manual. I work through the CD's questions, and if I both get a question wrong and don't understand the short explanation that is then provided, I turn to the relevant page in the book to read the more detailed explanation. If necessary, I'll expand to read the entire chapter in the book.

This gives a fairly directed approach to learning just enough to pass the test. Sure, we could all try to learn every one of the hundreds of pages of material in the manual, and maybe in a perfect world that would be ideal. But for those of us keen to simply extend our license that magic extra step, and if we're not going to need to go into the fairly advanced math to design and build our own R-C and other types of circuits, it is sufficient to simply adopt this directed approach to working through the 'need to know' material, and will save you hundreds of hours.

That is the great thing about this manual. You can approach it either comprehensively or selectively, and using the CD's random generated tests, you can check your knowledge progress and know when you're able to actually go to be tested with a high degree of confidence you'll pass.

I said this is one of the two best ways. The other excellent way is the online hamradiolicenseexam.com product, which claims to give you the skills you need in only 30 hours of study. Both are great, but I like ending up with the excellent, well laid out and clearly written book that you get if you choose this product, and it is good to support the ARRL too.

5.0 étoiles sur 5 Excellent Study Guide - But I used other resources as well to score 100%! 10 avril 2013
Par Charlie Hicks - Publié sur Amazon.com
Format: Broché Achat vérifié
This is a very thorough guide that is well worth getting. It not only has all the Rules + Regs you need to know, along with all technical theory, it also has the complete (700+) question pool and answers in the back separated by groups. I used this book as my primary study guide.

I did not use the CD at all. I did use QRZ.com to take practice tests and I also bought the Amateur Radio Exam Prep Extra Class iPhone app and I found the iPhone app invaluable. Anytime I had a few minutes - whether at home, on the road, waiting for someone, etc., I would take out my iPhone and start taking a practice test.

Here's how I studied and passed with 100%: I started the third week of January, 2013 after not being active on the air for 4 or 5 years. I held a General license. I first started looking online for resources and settled on QRZ and the iPhone app. When I first started taking the sample tests I was getting 40% - 50% on them. I quickly realized I needed to study so I bought this guide. I went through each section and took practice tests from each chapter in the book. When I didn't get something right, I'd go back and re-read it and try it again. I received this book on Jan 29th and took the test on Feb 9th. The book was a lifesaver.

In just over two weeks of studying quite a bit I got down to the last 3 days prior to the test date. In two of those days I went through the ENTIRE question pool twice and familiarized myself with the questions and the answers. This may seem extreme but I was finding certain things were confusing me when studying the theory. Over the last 2 days my sample testing grades went from about 80% - 85% to 95% - 98%. I never once got 100% on any practice test from any testing source (QRZ or iPhone app)!

When the VE test day came (Feb 9) I went in and took the test with a very high degree of assurance I would score well. After the test there were only two of the 50 questions I wasn't sure about. It turns out I got 100% and was very pleasantly surprised.

By the way - when taking the test and you aren't sure about the answer - always take you first hunch. You'll find that 80%+ of the time you'll be right.

Go for it - you'll be glad you did. If this 60+ year old who hasn't studied for a ham radio exam in 20+ years can do it, so can you.

This book was invaluable in my preparation - don't think twice - just get it.

3.0 étoiles sur 5 Great text, poor CD supplement 17 mars 2014
Par Capt J. D. Obenberger - Publié sur Amazon.com
Format: Broché Achat vérifié
The same author wrote all three of the ARRL's study guides for the three levels of FCC amateur radio licensing exams. In general, he is an excellent author, with some important few lapses. The Amateur Extra exam is by far, the hardest exam because of its theoretical and mathematical content, and because it's longer than the two prior exams for Tech and General classes; the Amateur Extra has fifty questions while the first two exams have 35. And there is serious math on the exam way past what I saw in Algebra II in high school, imaginary number and some pretty fancy work in trigonometry. Yikes. Before reading this book, I did not know that trig had anything to do with electronics! Like many other users of this book, I'm sure, I am not a math person. But the author really does skip a bit lightly and then plunges right into the deep end of the pool. I think that he expects that many users will be in a prep class and use this work as a backup. He does provide links to websites that cover the math and some other technical matters, but I think the readers have a right to expect this book to tell the whole story about understanding all of the questions and all of the answers, and, as related, he really does take the reader to two places at the deep end of the pool. Actually, a check of all ARRL-sanctioned classes within 75 miles of Chicago showed no scheduled classes for this exam, and going further in the search, the ones within 250 miles were held on weeknights, making it impossible for someone living here. I expect that the large majority of people around the US will be on their own. So I do expect the ARRL extra class manual to cover the turf in depth as the only instruction most candidates will have. Again, in general, this is an absolutely excellent work except for what I've mentioned, and a handful of others, typically "handling" stray questions from the published question pool here and there where he either rounds the corner without much of an explanation, presumably expecting the student to just blindly memorize the answer, or otherwise expects a bit too much of prior knowledge. My technique was to primarily rely on this book, reading chapters in stray moments for a month, and then to cram hard for about a total of ten hours during the final weekend before the test. I suplemented it by looking at some of the math web pages he mentions, and by printing out and intensely reviewing the free downloadable work by Jack Tiley that covers the same material; the bulk of Tiley's download is comprised of the test questions, all of them in the pool, and only the CORRECT answers, in some hard areas supplemented by an attempt to teach what it means, sometimes at length. He also has an appendix of formulas. Using these two works, I took the test a week ago today and passed on my first attempt, getting 7 questions wrong out of fifty, well within the pass range. I could have gotten 13 wrong and still passed. I think that I blew all of the questions relying on the fancier math that the test required, and got all or almost all of the text-based questions right. Perhaps if I'd spent more time trying to absorb the math, including side-excursions outside this book, I might have succeeded in actually learning this material. That light treatment of the higher math is my only big criticism, and in full context, I do think that this book really is well-written overall. If you use it as I did, and even if you blow all of the math, the odds are good that you will pass the exam with this book if you study it hard. The reason why I do not give the work four stars is because of the terrible and inadquate CD that is a selling point of the of the book. It's in an envelope in the back, and is intended to prepare sample test exams, picking at random from the questions in the published question pool, with the right number for each part. The major trouble is that the disc's designer is incompetent. Some of the questions present a diagram and ask such things as what the function of a particular identified component is. The question pool probably has ten to twenty such questions relying on diagrams. However, the design of this program includes a blue bar on each screen identifying that if you click there, the diagram on which the question is based will display. The trouble is that in every case, that blue bar covers the question! And when you click on it, the diagram covers the question! So, when sample exams are created that include diagram questions, you actually will never be able to answer the question based on the diagram, and that's a serious fault. Because the CD is a big selling point of the book, I could not give this product the four stars that it would otherwise deserve. In sum, a damn good and generally well-written text with a couple of flaws that may not be fatal, and a terrible CD that comes with it.

5.0 étoiles sur 5 A good way to study for and pass the Extra test 23 février 2014
Par Joe - Publié sur Amazon.com
Format: Broché Achat vérifié
The book goes into a lot of detail on all of the test sections of the Element 4 test for the extra class license. Some of the parts of the test don't need much explanation, such as the rules and regulations - those have to memorized. The theory, circuits, antennas, propagation, and other theory and practical parts are explained in plenty of detail.

Upon reading this book, you may feel overwhelmed. My suggestion would be to try the tests on the enclosed CD and scan the questions in the back of the book. It includes all 700 questions in the current pool both in writing and on the CD. All of the questions have references to where in the book the answer is explained. At least trying the questions will give you a sense of where you'll need to concentrate your efforts.

I went through all 700 questions 3 times and also took over 15 practice exams. When test day came, I scored 100% and thought that the actual test I got was one of the easier mix of questions that I had studied for. I spent about 5 or 6 weeks studying for this and probably could have passed the test (though not with a 100%) after 2 weeks. My background is in electrical engineering, although I've been in software design for many years.

Other resources are QRZ dot com and AD7FO's Amateur Radio Extra Class Syllabus.

Although I gave this 5 stars, one weakness, perhaps, is that the enclosed CD will run only on Windows (needs .NET). I have a Mac and tried to run the software in Wine but got various errors trying the install the program. I finally ended up installing it on a Windows 7 VM running on VirtualBox.

Read this book, take your time, study and you'll pass.

4.0 étoiles sur 5 THE book for those who want to know 22 août 2014
Par Paladin_Cody - Publié sur Amazon.com
Format: Broché Achat vérifié
If all you want to do is earn your Extra Class license, you can certainly do it with this book. But if just passing the test is not enough, and you really want to learn a lot of what is going on behind the questions then this is the ONLY book you want to buy. Ward Silver does an excellent job (most of the time) in explaining a lot of the theory and practice of what you SHOULD know if you are an Extra Class ham.

I learned a LOT from this manual. And for me at least, it made me want to know more. You won't learn everything from this manual, but it will send you a long way down the road to understanding how radio actually works and what is going on. In fact, it kind of makes you want to have another license level, so Silver can write another manual, advancing the state of your ham radio knowledge.

I gave the book only five stars because the writing was less clear in some areas than others. I learned a lot from all chapters, but Silver's writing is makes some things more clear, other things less clear. Luckily the less clear areas are pretty minimal and can be shored up on the ARRL web site.

I passed the Extra Class exam with ease, and this book was the only study material (other than a couple of articles on the ARRL website) that i used. This book is highly recommended for anyone who wants to pass the exam AND know what they are doing.
