My notes on the rules
Amateur radio lives in 47 CFR Part 97. The legal framework is broad because it covers everything from a handheld radio and a local repeater to HF, satellites, digital modes, and homebuilt equipment. This is the shorter list I use to remember the rules that follow me whenever I transmit.
The rule list and the courtesy list are not the same thing. The first comes from Part 97. The second is what I have picked up by listening and trying not to make the frequency harder for somebody else to use.
What the rules say
The individual license covers the named person
An individual amateur license belongs to the person named on the FCC license grant. It does not cover a spouse, children, other relatives, roommates, or everyone at the same address.
The station licensee remains responsible
For my individual station, I am the station licensee named on the FCC operator/primary station grant. A club station has its own station license and call sign. The station licensee is responsible for proper operation of the station, must designate the control operator, and must make the station and its records available if an FCC representative requests an inspection.
The FCC presumes that the station licensee is also the control operator unless the station records document someone else. Designating another amateur does not transfer all responsibility away: when the station licensee and control operator are different people, both are equally responsible for proper operation.
The control operator is responsible for each transmission
The control operator is a licensed amateur operator designated by the station licensee to be responsible for the station's transmissions and compliance with the FCC rules. The control operator must ensure the immediate proper operation of the station, regardless of whether the station is controlled locally, remotely, or automatically.
The control operator's license class sets the operating privileges available during that operation. Letting an Amateur Extra operator control my station may permit operation within that operator's Extra-class privileges; letting a Technician operator control it limits the operation to Technician privileges. Equipment ownership does not change that rule.
Every amateur station must have at least one control point. During local or remote control, the control operator must be at the control point. Only stations specifically authorized by Part 97 may operate under automatic control, and in those cases the control operator does not have to be present at a control point while the station transmits.
A family member or guest who is not licensed may speak as a third party only while a qualified control operator is present at the control point and continuously monitoring and supervising the participation. The guest does not become the control operator and does not gain permission to operate the station alone later.
Identify with the station call sign
Transmit the assigned call sign at the end of each communication and at least once every ten minutes during a communication. Identification must use a method authorized for the transmitting channel. On phone, say the call sign in English; a phonetic alphabet may be used to make it clear.
Portable, temporary-upgrade, special-event, and guest-control situations can have additional identification requirements. A self-assigned indicator cannot conflict with an indicator specified by the FCC or a prefix assigned to another country.
Stay inside the privileges of the control operator
The control operator's license class determines which amateur frequency segments the station may use. The band, frequency segment, and emission rules determine which modes are permitted there.
A frequency that appears inside an amateur band is not automatically available for every license class or every mode. Check the current rules before transmitting, especially near a band edge. Account for the full occupied bandwidth of the signal—not just the frequency shown on the radio display.
Use only the power you need
An amateur station must use the minimum transmitter power necessary to carry out the desired communication.
The general ceiling of 1.5 kW peak envelope power is not blanket permission to use that power everywhere. Lower limits apply to particular bands, frequency segments, license classes, locations, and emission types. Antenna gain and radiated-power limits also matter in rules that specify ERP or EIRP.
Keep the signal clean
Use no more bandwidth than necessary for the information rate and emission type. Keep modulation products inside the authorized band or segment, control splatter and key clicks, and reduce spurious emissions as far as practicable.
If a station causes harmful interference through spurious emissions, the licensee must take steps to eliminate it. Amateur radio allows experimentation and home construction, but that freedom leaves responsibility for the transmitted signal with the station licensee and control operator. Separate certification rules apply to some external RF power amplifiers.
Share the frequencies
No amateur frequency is assigned for the exclusive use of one station. Station licensees and control operators must cooperate in selecting frequencies and using the spectrum effectively. Willful or malicious interference is prohibited.
Emergency communications have priority. A scheduled net, long conversation, contest contact, or repeater user does not own a frequency.
What you may not transmit
The prohibited-transmission rule includes communications for hire or material compensation and communications in which the station licensee or control operator has a pecuniary interest, subject to specific exceptions in Part 97.
It also prohibits music by phone except where specifically allowed, communications that facilitate a criminal act, obscene or indecent language, false or deceptive messages or identification, and messages encoded for the purpose of obscuring their meaning except where the rules provide an exception.
Amateur radio is not a replacement for ordinary business, dispatch, broadcasting, or another radio service that could reasonably carry the traffic on a regular basis.
Amateur radio is not broadcasting
Part 97 defines broadcasting as transmissions intended for reception by the general public, whether received directly or relayed. An amateur station may not broadcast, produce or gather programming for broadcasters, or send one-way communications unless a specific Part 97 rule authorizes the transmission.
The intent and the rule authorization matter. Calling CQ is meant to establish two-way communication, so it is not the same as running a radio program for a public audience. Part 97 also permits certain one-way transmissions, including brief transmissions needed to adjust a station or establish two-way contact, telecommand, emergency communications, Morse-code practice, and information bulletins directed only to amateur operators.
There are narrow exceptions involving immediate safety-of-life or property information when no other reasonable means is available, and occasional retransmission of specified United States Government propagation, weather, or manned-spacecraft communications. Those exceptions do not create permission to operate a music station, podcast, news channel, general-audience livestream, or regular one-way show over amateur frequencies.
Third-party messages have limits
An unlicensed person may participate while the control operator is present and continuously supervising, but international third-party communication depends on whether the other country's administration has an arrangement with the United States. Emergency and disaster-relief provisions are addressed separately in the rule.
The licensed control operator is still responsible for the station, its identification, and the content being transmitted.
Repeaters may limit access
A repeater can be automatically controlled, and limiting its use to selected stations is permitted. An access tone or a frequency displayed in a directory is not a promise that everyone may use the system.
Follow the repeater operator's published access requirements and operating rules. Coordination helps resolve interference between repeaters, but it does not give anyone ownership of an amateur frequency.
Emergencies and distress
Part 97 does not prevent an amateur station from using any means of radiocommunication at its disposal to meet essential communication needs involving the immediate safety of human life or immediate protection of property when normal communication systems are unavailable.
A station in distress may use any means at its disposal to attract attention, report its condition and location, and obtain assistance. These are exceptional provisions for actual safety and distress needs—not a general shortcut around the operating rules.
What I learned by listening
- Listen before transmitting. A frequency can sound empty when a station I cannot hear is already talking to somebody I can.
- Ask whether a frequency is in use before starting a longer contact, especially on HF. A short pause is cheaper than landing on an existing conversation or net.
- Leave room around band edges. My transmitted signal is wider than the single carrier frequency shown on the display.
- Use the local band plan and repeater coordination information as operating guidance. They help people share spectrum, but they do not replace the FCC rules.
- Pause after keying a repeater. Links, tone decoders, and networked systems may need a moment before they pass audio.
- Keep transmissions reasonably short and leave gaps. Somebody with priority or emergency traffic needs a place to break in.
- Give a full call sign clearly. Phonetics help when the signal is weak, but speed and cleverness do not make an identification more legal.
- Use the least power that works. A better antenna, cleaner installation, or better operating time often helps more than another amplifier.
- Follow the repeater operator's access rules. Part 97 permits a repeater to limit which stations may use it.
- Calling frequencies, contest segments, nets, and local customs are operating conventions. They help organize activity, but none makes a frequency the permanent property of one group.
- If I am unsure about a frequency, mode, power level, or international contact, I stop and check before transmitting.
I am not an attorney or lawyer; these are my personal notes as a newcomer, not legal advice, and I may have something wrong. The FCC rules control — read 47 CFR Part 97 for the full rule text.
