The FCC regulates Amateur Bands by requiring individuals to have licenses before transmitting. There are various licensing levels, each with its own level of privileges. The higher your license, the more frequencies you are allowed to transmit on. The first license level is Technician, followed by General, and then Extra.
In order to receive a license, you must first pass a short multiple-choice test of approximately 35 questions for Technician and General licenses, and 50 questions for Extra licenses. The Technician exam tests your knowledge of basic electronics, FCC regulations, and behavioral guidelines for transmitting on amateur radio bands. Exams are given periodically in multiple locations.
The American Radio Relay League (ARRL) publishes instructional books and sample questions to help prepare you for your exam. For more information, please visit the ARRL Question Pools.
