How the FCC Manages the Amateur Radio Spectrum (Part 97)

FCC Part 97 of Title 47, Code of Federal Regulations, is the comprehensive set of rules governing amateur radio in the United States. Understanding Part 97 is not just regulatory compliance — it is the foundation of how the amateur radio community organizes its activities, allocates frequencies, and self-governs through the Auxiliary program.

The Basis and Purpose of Amateur Radio

Part 97 opens by stating the basis and purpose of the amateur radio service. This is not just bureaucratic preamble — these stated purposes shape how ambiguous situations are interpreted and how the FCC evaluates rule changes:

• Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service
• Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art
• Encouragement and improvement of the amateur service through rules which provide for advancing skills in communication and technical phases of the art
• Expansion of the existing reservoir of trained operators, technicians, and electronics experts
• Continuation and extension of the amateur's unique ability to enhance international goodwill

Key Part 97 Concepts

Control Operator

Every amateur radio transmission must have a control operator — a licensed amateur responsible for the proper operation of the station. The control operator must hold at least the license class required for the frequency being used.

Station Identification

Amateur stations must identify with their FCC-assigned call sign at least every ten minutes during a contact and at the end of each transmission. Phone stations identify in English; CW stations identify in Morse code.

Prohibited Transmissions

Part 97 prohibits music, encrypted communications, one-way transmissions (with exceptions for beacons and control links), and any transmission intended to facilitate a crime. Amateur radio may not be used for business communications or for compensation.

Self-Governance Through the Auxiliary

The FCC Amateur Auxiliary is a program of volunteer monitors who enforce Part 97 rules within the amateur community. Extra class operators serve as OOs (Official Observers) who identify and report Part 97 violations, maintaining the self-policing tradition that has kept amateur radio largely interference-free for over a century.
