BG TECH. VERSION III 2001/2/28 INTRODUCTION TO AMATEUR RADIO Your transceiver is the perfect first radio for anyone entering the exciting world of amateur radio, s well as a great additional transceiver for the experienced amateur radio operator. Your transceiver opens a door for you to the world from almost anywhere! All you need is an Amateur Radio Operator’s License (Technician Class or higher) issued by the Federal Communications Commission (FCC). If you do not have a license, it is easier than ever to get one, and help from licensed operators is available. Here are a few tips to help you get started. You can turn on your transceiver and scan the entire band to hear what is going on; however, do not attempt to transmit until you get your license. If you transmit without a license, you are in violation of federal law that can lead to severe penalties. Note that ham operators take the FCC rules very seriously and want nothing to do with “bootleggers” – their term for people who operate without a license. Find out if there is a ham radio club in your area. Most clubs welcome new transmissions, write to the American Radio Relay League (ARRL) at the following address to find out how to cntact a local affiliate. The ARRL is the national organization representing amateur radio in the United States. The league has more than 150,000 members. Most are ham operators, or members in the process of obtaining their license. The American Radio Relay League 225 Main Street Newington, CT06111 http://www.arrl.org Starting for the license exams. Do not be intimidated by the word “study” because most people can go from knowing absolutely nothing about amateur radio to passing the Novice and Technician written exams in less than a month. The exams test your knowledge of basic radio regulations and elementary radio theory. Many clubs hold license classes which can be a fun and easy way to learn about amateur radio. There are good books, cassette tapes, computer programs, and many other study aids available. Your local RadioShack store sells FCC License Preparation study guides for amateur radio operator licenses. While you are no longer required to
BG TECH. VERSION III 2001/2/28 learn Morse code for a Technician Class license, we encourage you to learn it anyway so you can advance to higher levels of operating privileges. There is no fee to take the Novice exam. As soon as you pass the Novice exam, you can immediately take the Technician exam. All license level tests are administered by a three-member Volunteer Examiner Team. Contract the ARRL for a schedule of exam opportunities in your area. The Technician Class license lets you use the transceiver to communicate directly with other operators, and use repeaters for distant communication. Amateur radio is a great hobby that has enriched the lives of millions of people all over the world. The ARRL would be glad to hear from you if you need more information or would like to join!
