GROL+RADAR is the study manual for the new 2009 FCC Commercial Radio Operator / Maintainer License examinations that are mandatory for exams on and after 12/26/2009. GROL+RADAR covers Element 1, Marine Radio Operator Permit (MROP); Element 3, General Radio Telephone Operator License (GROL); and Element 8, Ship RADAR Endorsement. The book is fully illustrated and contains the exact questions and answer choices from the official FCC question pools. Author Gordon West provides an educational answer explanation for each question, telling the reader which answer is correct and discussing why it is correct. GROL+RADAR also is available with study software that allows the student to take practice examinations on their PC. A new feature of the software includes the answer explanations from the book. If the student answers the question wrong on the software, the correct answer appears along with the Gordon West explanation to reinforce learning. See ISBN 9780945053613 for the book and software package.
Well, I guess this was as good as such a book can be. I passed Elements 1 and 3 with 100% and 96% respectively, so it certainly served it's purpose. Be prepared for a slog, though.
In this book, West lists all the multiple choice questions on the MROP and GROL exams, gives the correct answer, then adds a bit of explanation. I did find his explanations helpful on material I had never seen before. On things like, ya know, maritime and aviation radio law (because *those* are things I expected to study in my lifetime. Oh well, life is weird). The test requires a lot of rote memorization of things like frequencies and VHF channels and such. As I don't have any background in aviation or boating, it was tricky to get those into my thick skull.
My approach was to read this cover to cover. I don't recommend that approach. Instead, I suggest going through the test at https://www.fcctestonline.com/ and consulting this book when you need a bit of extra help.
