style="font-size:15px;">      Chapter 7 provides full coverage of call signs. In this section, I give you a brief overview.

      Call-sign prefixes and suffixes

      Each call sign is unique. Many call signs contain NØ or AX, for example, but only one call sign is NØAX. Each letter and number in a call sign is pronounced individually and not as a word — “N zero A X,” for example, not “No-axe.”

      

Hams use the Ø (ALT-0216 on keyboards) symbol to represent the number 0, which is a tradition from the days of teleprinters and typewriters. It avoids confusion between capital-O and zero.

      Ham radio call signs around the world are constructed of two parts:

       Prefix: The prefix is composed of one or two letters and one numeral from Ø to 9. (The prefix in my call sign is NØ.) It identifies the country that issued your license and may also specify where you live within that country. For U.S. call signs, the numeral indicates the call district of where you lived when your license was issued. (Mine was issued when I lived in St. Louis, Missouri, which is part of the tenth, or Ø, district.)

       Suffix: The suffix of a call sign, when added to the prefix, identifies you, the individual license holder. A suffix consists of one to three letters. No punctuation characters are allowed — just letters from A to Z. (The suffix in my call sign is AX.)

      

The ITU assigns each country a block of prefix character groups to create call signs for all its radio services. All U.S. licensees (not just hams) have call signs that begin with A, K, N, or W. Even broadcast stations have call signs such as KGO or WLS. Most Canadian call signs begin with VE. English call signs may begin with G, M, or 2. Germans use D (for Deutschland) followed by any letter; almost all call signs that begin with J are Japanese, and so on. You can find the complete list of ham radio prefix assignments at ac6v.com/prefixes.php.

      Class and call sign

      As a newly licensed ham, your license class will be reflected in your assigned call sign. When you get your first license, the FCC assigns you the next call sign in the heap for your license class, in much the same way that you’re assigned a license plate at the department of motor vehicles. Just as you can request a specialty license plate, you can request a special vanity call sign — within the call sign rules, of course. The higher your license class, the shorter and more distinctive your chosen call sign can be.

      Preparing for Your License Exam

      IN THIS CHAPTER

      

Breaking down the exam

      

Finding resources to get ready

      

Getting help from a mentor

      You’ve decided to take the plunge and get your ham radio license. Congratulations! Although you can’t just run down to the store, buy your gear, and fire it up, becoming licensed isn’t that hard. A lot of resources are available to prepare you for the ham radio exam. This chapter gives you some pointers on how best to prepare so that you will enjoy studying and do well at test time. (Exams and exam sessions are also referred to as tests or test sessions. I use mostly exam in this chapter.)

      This chapter doesn’t teach the answers to the exam’s specific questions — that’s the job of study guides and manuals. There are quite a few questions in the exam question pools! Use one of the several excellent print and online study resources that review each individual question. This book will help you through the process of studying and passing your exam.

      The exam for each license class is called an element. The written exams for Technician, General, and Amateur Extra licenses (see Chapter 4) are Elements 2, 3, and 4, respectively. (Element 1 was the Morse code exam, which has been dropped.)

      Your studies will focus on the question pool, the complete set of actual questions used on the exam. The questions are available to help you study. The exam that you’ll take is made up of a selection of questions from that pool.

      The exam covers four basic areas:

       Rules & Regulations: Important rules of the road that you have to know to operate legally including some important definitions.

       Operating: Basic procedures and conventions that hams follow on the air to be effective. In essence, you’ll learn “radio manners.”

       Basic Electronics: Elementary concepts about radio waves and electronic components, with some basic math involved. There are some equipment questions, too.

       RF Safety: Questions about how to transmit safely.

      The exam must include a certain number of questions from each area; questions are selected randomly from those areas. The Technician and General exams have 35 questions; the Amateur Extra has 50. If you answer at least three-quarters of the questions correctly, you pass.

      

Because the exam questions are public, you’ll experience a strong temptation to memorize the questions and answers. Don’t! Take the time to understand as much of the material as you can, memorizing only what you must. After you do get your license, you’ll find that studying pays off when you start operating.
