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.

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.

The Quintessential Study Guide for the Extra Class Exam 8 mai 2011
Par D Anderton - Publié sur Amazon.com
Format: Broché
NB: This edition has expired. The pool of license questions is changed every four years. Be sure to get the latest edition.

If you are contemplating taking the element 4 exam--this book is the quickest and surest route to successful completion.

The element 4 (extra class) exam consists of 50 multiple choice questions taken from a pool of over 700 questions.

The technical questions are tougher than for the lower grade licenses--you will need to know how to work with complex numbers, calculate impedances, describe the salient features of a Smith Chart, etc.

The exam topics cover 10 subjects:

E1 FCC Rules
E2 Operating Principles and Procedures
E3 Radio Wave Propagation
E4 Amateur Radio Technology and Measurements
E5 Electrical Principles
E6 Circuit Components
E7 Practical Circuits
E8 Signals and Emissions
E9 Antennas and Transmission Lines
E0 Safety

Some familiarity with general electronics and sophomore circuit theory will likely see you through the technical sections (E5-E7)--but the test also includes several questions on FCC Rules (E1) and amateur radio practice (E2) that simply must be committed to memory. For example:

>>> What transmit and receive time sequencing is normally used on 144 MHz when attempting Earth-Moon-Earth contact?

This book covers all of the questions (and answers). The text is well written and I found it a joy to read. There is a companion CD with software that includes all of the questions (and answers). You can review by technical topic (e.g., E3) or by book chapter. You can also generate an unlimited number of sample exams.

I purchased this book and studied the contents diligently for two weeks. I just returned from the exam session--and I PASSed. My sincere thanks go to the author Ward Silver (N0AX), the contributing editor Mark Wilson (K1R0) and to the production staff!

I enthusiastically recommend this book.

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.

10th Edition needed after Jun 2012 30 mai 2012
Par College Professor - Publié sur Amazon.com
Format: Broché
This is a great book for studying for the Extra Class exam. Very good chapters that are arranged by topic, not by question # so this is not a 'just memorize' book but a real study manual for concepts. Each sub-section has questions from the exam so you can test your knowledge. There are tons of practice online exams to help you.

*** NOTE: *** You will need the _10th_ edition if you are taking the exam after Jun 30, 2012 because that is when the FCC changes the questions.
