ARRL Technician Class is a type of amateur radio license granted by the American Radio Relay League (ARRL) to individuals who have passed an examination demonstrating their knowledge of basic radio theory, regulations, and operating practices.

The ARRL Technician Class license is the entry-level license for amateur radio operators in the United States. It provides the operator with basic privileges on specific frequency bands and modes of operation, including voice and digital modes on very high frequency (VHF) and ultra-high frequency (UHF) bands.

To qualify for the ARRL Technician Class license, an individual must pass an examination consisting of 35 multiple-choice questions covering topics such as basic electronic theory, regulations, operating practices, and safety. The exam is designed to test the individual's knowledge of the basic concepts and practices of amateur radio and to ensure they are aware of the rules and regulations governing the operation of amateur radio stations.

Holders of the ARRL Technician Class license have access to a limited range of frequencies and modes of operation, including voice and digital modes on VHF and UHF bands, such as the 2-meter and 70-centimeter bands. They can communicate with other amateur radio operators within a local area and participate in various activities, such as contests, public service events, and emergency communications.

The ARRL Technician Class license provides a starting point for individuals who wish to explore the world of amateur radio and learn more about its technical and operational aspects. Many amateur radio operators begin with this license and later advance to higher levels of licensing, such as the ARRL General Class and Amateur Extra Class licenses, to gain additional privileges and knowledge.
