FCC Part 97 Rules: Complete Guide to Amateur Radio Regulations

What is FCC Part 97 and Why it Matters

Part 97 consists of six subparts (A through F) and two appendices. Subpart A contains fifteen sections, numbered 97.1–29. Subpart A defines a number of terms relevant to the provisions of Part 97 and establishes the amateur service as a "voluntary, noncommercial communications service" devoted to advancement of the amateur art, the skills associated with it, and the international goodwill that it brings, especially with regard to the provision of emergency communications. The significance of Part 97 extends far beyond mere regulatory compliance. These rules create the legal framework that allows amateur radio to operate as a self-policing service while maintaining protection from harmful interference. Understanding these regulations helps operators maximize their privileges while avoiding violations that could result in enforcement action or loss of license.

History and Evolution of Amateur Radio Regulations

The amateur service has evolved significantly since its early days, and Part 97 reflects this progression. This guide includes the complete Part 97 rules from Title 47 of the Code of Federal Regulations effective January 8, 2024. Recent changes continue to modernize the rules while preserving the fundamental principles of amateur radio. Recent developments include significant changes to data transmission rules. The Commission adopts this R&O and FNPRM to eliminate the baud rate limitation and establish a bandwidth limitation in certain amateur bands. The item also proposes removal of the baud rate limitation in several additional bands. These modifications reflect the FCC's ongoing effort to adapt amateur radio regulations to technological advancement.

Relationship Between Part 97 and Other FCC Rules

Part 97 doesn't operate in isolation. It references numerous other sections of the CFR, particularly regarding RF exposure limits, antenna structure regulations, and equipment certification requirements. Amateur operators must be familiar with how Part 97 interacts with these broader telecommunications regulations. The rules also establish international coordination requirements and define how amateur radio operates within the International Telecommunication Union (ITU) framework. This ensures that U.S. amateur operations remain compatible with global amateur radio practices.

Amateur Radio Service Fundamentals Under Part 97

Basis and Purpose of the Amateur Service

Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service, particularly with respect to providing emergency communications. 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 both the communication and technical phases of the art. Expansion of the existing reservoir within the amateur radio service of trained operators, technicians, and electronics experts. Continuation and extension of the amateur's unique ability to enhance international goodwill. These five fundamental purposes define why amateur radio exists and guide all regulatory decisions regarding the service. Every amateur radio activity should advance one or more of these objectives.

Amateur Radio Operator Responsibilities

Each amateur station must be operated in accordance with good engineering and good amateur practice. Each station licensee and each control operator must cooperate in selecting transmitting channels and in making the most effective use of the amateur service frequencies. This establishes the self-policing nature of amateur radio, where operators are expected to use good judgment and technical knowledge. Control operator. An amateur operator designated by the licensee of a station to be responsible for the transmissions from that station to assure compliance with the FCC Rules. The control operator concept ensures that every transmission has a licensed amateur responsible for compliance with regulations. At all times and on all frequencies, each control operator must give priority to stations providing emergency communications, except to stations transmitting communications for training drills and tests in RACES. This priority system ensures that amateur radio can fulfill its emergency communication mission when needed.

Station Identification Requirements

Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station. The call sign must be transmitted with an emission authorized for the transmitting channel in one of the following ways: By a CW emission. When keyed by an automatic device used only for identification, the speed must not exceed 20 words per minute; By a phone emission in the English language.

Frequency Allocations and Band Plans

Amateur Frequency Bands Overview

The following transmitting frequency bands are available to an amateur station located within 50 km of the Earth's surface, within the specified ITU Region, and outside any area where the amateur service is regulated by any authority other than the FCC. These allocations form the spectrum foundation for all amateur radio activities. Amateur radio operates across a wide range of frequencies, from the low frequency bands near 136 kHz up through the millimeter wave bands above 241 GHz. Unless otherwise noted, the maximum power output is 1500 watts PEP. Novice/Technicians are limited to 200 watts PEP on HF bands. The frequency allocations are carefully structured to accommodate different license classes and operating modes. Band Allocations define the frequency ranges the FCC has allocated for amateur radio use in the United States. Each band is subdivided into segments with specific rules about which emission modes are permitted and which license classes may transmit. The FCC issues four active license classes — Technician, General, Amateur Extra, and the grandfathered Advanced class.

Frequency Sharing and Coordination

On shared bands, amateurs may be secondary users and must not cause harmful interference to primary services. The 60-meter band is a notable example — amateur use is restricted to five specific channels with a maximum ERP of 100 W relative to a dipole. The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. Amateurs can not cause inference to and must accept interference from the Primary Government users. The NTIA says that hams planning to operate on 60 meters "must assure that their signal is transmitted on the channel center frequency."

International Coordination Requirements

Amateur radio operates within international frequency coordination agreements. International agreements assign amateur radio bands which differ by region. These agreements ensure that amateur radio can operate effectively across international boundaries while minimizing interference to other radio services. The ITU divides the world into three regions, and frequency allocations may vary between regions. U.S. amateurs must understand these differences when operating in other countries or when communicating with stations in different ITU regions.

License Classes and Operating Privileges

Technician Class Privileges and Limitations

Higher-class licenses unlock additional frequency segments, particularly on HF (below 30 MHz). Technicians have full VHF/UHF privileges and limited HF access: 10 meters plus CW on narrow portions of 80, 40, and 15 meters at 200 W PEP. Technician class licensees have extensive privileges on VHF and UHF bands, making this license class ideal for local and regional communications. The limited HF privileges provide introduction to long-distance communication while encouraging advancement to higher license classes.

General Class Frequency Access

General class operators gain significant additional frequency privileges, particularly on the HF bands that support worldwide communication. In the 40-meter band, the General class license allows transmission for voice between 7.175 MHz and 7.300 MHz but not between 7.125 and 7.175 MHz. 28.000 MHz to 28.025 MHz and 21.275 MHz to 21.300 MHz are both allowed spaces to transmit on with a general class license. The General class license provides access to most amateur frequency segments, enabling participation in most amateur radio activities while still providing incentive for advancement to Amateur Extra class.

Amateur Extra Class Benefits

Amateur Extra license holders have the broadest access across the amateur radio spectrum, including exclusive segments in various bands. Below are detailed breakdowns for key bands where Amateur Extra licensees have additional privileges. These tables provide a comprehensive overview of the expanded and exclusive privileges available to Amateur Extra license holders, showcasing the wide range of frequencies and modes they can explore. Amateur Extra class operators have privileges over all other operator classes, thus if a portion of the phone allocation in a band is reserved for the exclusive use of Amateur Extra operators, then it will be the portion of the band towards the center for the benefit of the lower SWR and not towards the upper end where antennas generally sport a higher SWR. Therefore it follows that if General class operators aren't able to use the portion of a phone allocation towards the center of a band they will be relegated to using the phone portion towards the top end.

Reciprocal Operating Agreements

CEPT radio amateur license. A license issued by a country belonging to the European Conference of Postal and Telecommunications Administrations (CEPT) that has adopted Recommendation T/R 61-01 (Nice 1985, Paris 1992, Nicosia 2003). These agreements allow qualified foreign amateurs to operate in the United States and vice versa.

Technical Standards and Equipment Requirements

Spurious Emission Limits

Spurious emission. An emission, or frequencies outside the necessary bandwidth of a transmission, the level of which may be reduced without affecting the information being transmitted. These unwanted emissions must be controlled to prevent interference to other services. For transmitters installed after January 1, 2003, the mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency below 30 MHz must be at least 43 dB below the mean power of the fundamental emission. For transmitters installed on or before January 1, 2003, the mean power of any spurious emission from a station transmitter or external RF power amplifier transmitting on a frequency below 30 MHz must not exceed 50 mW and must be at least 40 dB below the mean power of the fundamental emission.

Bandwidth Limitations by Band

Bandwidth. The width of a frequency band outside of which the mean power of the transmitted signal is attenuated at least 26 dB below the mean power of the transmitted signal within the band. This technical definition establishes how bandwidth is measured for compliance purposes. Recent rule changes have modernized bandwidth restrictions. The Commission adopts this R&O and FNPRM to eliminate the baud rate limitation and establish a bandwidth limitation in certain amateur bands. These changes reflect technological advancement while maintaining spectrum efficiency.

RF Exposure Compliance Requirements

Before causing or allowing an amateur station to transmit from any place where the operation of the station could cause human exposure to RF electromagnetic field levels in excess of those allowed under § 1.1310 of this chapter, the licensee is required to take certain actions. The licensee shall ensure compliance with the Commission's radio frequency exposure requirements in §§ 1.1307(b), 2.1091, and 2.1093 of this chapter, where applicable. Recent changes to RF exposure rules have updated amateur radio requirements. For applicants and licensees in the Amateur Radio Service, we substitute our general exemption criteria for the specific exemption from routine evaluation based on power alone in Section 97.13(c)(1) and specify the use of occupational/controlled limits for amateurs where appropriate. In a lengthy document in ET Docket 19-226 released on December 4 that addresses a broad range of RF safety issues, the FCC said current amateur radio RF exposure safety limits will remain unchanged, but that the amateur-specific exemption from having to conduct an RF exposure evaluation will be replaced by the FCC's general exemption criteria. Under the revised Section 97.13(c)(1), "In lieu of evaluation with the general population/uncontrolled exposure limits, amateur licensees may evaluate their operation with respect to members of his or her immediate household using the occupational/controlled exposure limits in Section 1.1310, provided appropriate training and information has been accessed by the amateur licensee and members of his/her household," the amended rule says. "RF exposure of other nearby persons who are not members of the amateur licensee's household must be evaluated with respect to the general population/uncontrolled exposure limits. Appropriate methodologies and guidance for evaluating Amateur Radio Service operation is described in the Office of Engineering and Technology (OET) Bulletin 65, Supplement B," the revised rule concludes.

Type Acceptance and Certification

Amateur equipment must meet certain technical standards, though the requirements differ from commercial equipment. Part 97 allows amateurs considerable flexibility in equipment modification and construction, provided the resulting equipment complies with technical standards and spurious emission limits.

Operating Procedures and Third Party Traffic

Proper Operating Procedures

Each amateur station must be operated in accordance with good engineering and good amateur practice. No amateur operator shall willfully or maliciously interfere with or cause interference to any radio communication or signal. These fundamental requirements establish the foundation for all amateur radio operations. Good amateur practice encompasses technical competence, courteous operating procedures, and spectrum efficiency. Operators should use the minimum power necessary to maintain communication and select frequencies that minimize interference to ongoing operations.

Third Party Traffic Restrictions

An amateur station may transmit messages for a third party to: Any station within the jurisdiction of the United States. Any station within the jurisdiction of any foreign government when transmitting emergency or disaster relief communications and any station within the jurisdiction of any foreign government whose administration has made arrangements with the United States to allow amateur stations to be used for transmitting international communication Third party communications. A message from the control operator (first party) of an amateur station to another amateur station control operator (second party) on behalf of another person (third party). This definition clarifies what constitutes third party traffic and when special restrictions apply. At the end of an exchange of international
