This page is part of the N0NJY General Class self-study course for Technician operators upgrading to General.
The rules that govern amateur radio in the United States are found in Title 47 of the Code of Federal Regulations, Part 97. Every licensed amateur operator is expected to know and follow these rules. This module covers Part 97 in enough depth that you understand not only what the rules say, but why they exist, how to find them, and how to interpret them correctly when a situation arises that the exam never covered.
This is not a section to skim. The rules are the foundation on which everything else in amateur radio rests.
The Code of Federal Regulations (CFR) is the body of rules published by U.S. federal agencies. It is organized into Titles by subject area, then Parts within each Title, then Sections within each Part. Amateur radio lives at:
Title 47 — Telecommunication — Part 97 — Amateur Radio Service
When you see a reference written as 47 CFR §97.119, that means Title 47, Part 97, Section 119. You will see this notation throughout this course and in any serious amateur radio publication.
The full text of Part 97 is available free at two sources you should bookmark:
| Subpart | Title | Key Sections |
|---|---|---|
| A | General Provisions | 97.1–97.23 — Basis, purpose, definitions, station authorization, callsigns |
| B | Station Operation Standards | 97.101–97.133 — Control operator, ID, prohibited transmissions, emissions, power |
| C | Special Operations | 97.201–97.223 — Auxiliary, beacon, repeater, space, Earth stations |
| D | Technical Standards | 97.301–97.321 — Authorized frequencies, emission types, power limits, antenna structures |
| E | Emergency Communications | 97.401–97.407 — RACES, emergency, disaster communications |
| F | Qualifying Examination Systems | 97.501–97.527 — VE program, exam requirements, question pools |
Rules are written precisely, and the exact words matter. When you read a Part 97 rule, pay attention to these signal words:
When a rule says you "must" use the minimum power necessary to carry out the desired communication (§97.313(a)), that is not a suggestion — it is a legal requirement. When a rule says you "may" use automatic control for a repeater station, that means it is permitted but not required. Understanding this distinction matters when someone challenges your operating practices.
Section 97.1 states the five reasons amateur radio exists in the FCC's view. These are not just exam trivia — they define the entire philosophy of the Amateur Radio Service and are the foundation on which every other rule is built. The five purposes are:
Notice that emergency communications appears in the very first purpose. This is not an accident. The FCC has always viewed amateur radio's emergency communication capability as central to its reason for existing. When you understand this, many of the rules — including the prohibition on commercial use and the requirement to identify — make more sense as part of a coherent system.
Section 97.3 defines the terms used throughout Part 97. You should be familiar with several key definitions because the exam tests them and they affect your operating every day.
Amateur operator (§97.3(a)(1)): A person named in an amateur operator/primary station license grant. Not just someone who passed the exam — someone who holds a current grant.
Amateur service (§97.3(a)(4)): A radiocommunication service for the purpose of self-training, intercommunication, and technical investigations carried out by amateur operators. The word "self-training" is significant — the entire service is built around the idea of personal education and experimentation.
Amateur station (§97.3(a)(5)): A station in the amateur service consisting of the apparatus necessary for carrying on radiocommunications.
Control operator (§97.3(a)(13)): An amateur operator designated by the licensee of a station to be responsible for the transmissions from that station. This definition is the foundation of the control operator rules discussed later in this module.
Control point (§97.3(a)(14)): The location at which the control operator function is performed. On a remotely controlled station this may be miles from the transmitter.
RACES (§97.3(a)(38)): Radio Amateur Civil Emergency Service. A part of the amateur service for providing emergency communications to government entities.
Space station (§97.3(a)(40)): An amateur station located more than 50 km above Earth's surface.
Third party (§97.3(a)(44)): A person on whose behalf an amateur operator transmits a radiocommunication. A person who is not a licensed amateur speaking through your station is a third party.
No amateur station shall transmit without a station authorization, which for most operators is the operator/primary station license grant issued by the FCC. Your license grants you both operator and station privileges. You must have a current FRN (FCC Registration Number) on file with the FCC. The ULS (Universal Licensing System) database is where your license lives.
When transmitting, every amateur station must have a control operator. This is one of the most important rules in Part 97 and one of the most misunderstood by new operators. The control operator is the licensed amateur who is responsible for the station's transmissions at that moment.
Amateur operator licenses are granted in five classes: Technician, General, Amateur Extra (and the legacy Novice and Advanced classes, still valid if held). Each class authorizes different frequency privileges and operating capabilities.
New license applications must be filed electronically through the FCC ULS. After passing an exam, the applicant must obtain an FRN if they do not already have one, then file the application. The license does not take effect until it appears in the ULS database — not when you pass the exam, not when the VE team submits the paperwork.
Amateur licenses are valid for ten years and must be renewed through the ULS. Licenses in the grace period (up to two years after expiration) may be renewed but cannot be used for operating until renewed. Operating on an expired license is a violation.
Subpart B contains the day-to-day operating rules that every amateur operator must follow. These sections govern how you operate, not just what frequencies you use.
This section establishes that each amateur station must be operated in accordance with good engineering and good amateur practice. This phrase — "good engineering and good amateur practice" — appears throughout Part 97 and in exam questions. It is a catch-all standard that allows the FCC to address poor operating or technical practices even when no specific rule covers the exact situation.
Good engineering and good amateur practice means your station should not cause interference, your signal should be clean, your power should be appropriate, and your operating behavior should reflect the traditions of the amateur service. If you are doing something that a reasonable, experienced amateur operator would recognize as wrong, it probably violates this standard even if no specific rule addresses it.
The station licensee is responsible for the proper operation of the station at all times. This is true even when another licensed operator is acting as control operator. If you allow your station to be used and it causes problems, you share responsibility. Choose carefully who you allow to use your station.
The control operator is responsible for the station's transmissions at the time of operation. If the control operator and the station licensee are different people, they share responsibility for the station's compliance. The control operator may only operate within the privileges of whichever license class is lower — their own or the station licensee's. A General Class operator cannot operate a station on Extra-only frequencies just because the station licensee is an Extra.
A non-US citizen who holds an amateur license from a country with which the US has a reciprocal operating agreement may operate in the US under the privileges authorized by their home country license or the US equivalent, whichever is more restrictive. This is relevant when a foreign amateur visits your shack or operates from the US.
This section defines the three types of station control, all of which appear on the General Class exam:
Local control (§97.109(b)): The control operator is at the control point, which is at or within sight of the transmitter. The most common type of control for home stations.
Remote control (§97.109(c)): The control operator is at a control point that is not at the transmitter location. The control operator must be capable of terminating transmissions immediately. Remote control is common with internet-connected stations (RemoteHams, SDR platforms, etc.). All Part 97 rules apply as if the operator were physically at the station.
Automatic control (§97.109(d)): The station transmits without a control operator monitoring it. Repeaters and beacon stations operate under automatic control. Only specific station types may operate under automatic control. A simple HF transceiver running unattended is not authorized for automatic control.
An amateur station may transmit the following types of communications:
What is notably absent: commercial communications. Amateur radio may not be used for communications in which the operator or the station has a pecuniary (financial) interest. This is one of the most fundamental restrictions in the service.
This section lists what you may not transmit. The key prohibitions that appear on the General exam and matter in real operating:
Third-party communications means transmitting a message on behalf of a person who is not a licensed amateur. This is permitted domestically without restriction. Internationally, it is only permitted with countries that have a formal third-party agreement with the United States.
The ARRL maintains a current list of countries with which the US has third-party agreements. This list changes occasionally as new agreements are made or old ones lapse. Before passing international third-party traffic, verify the destination country is on the current list. Passing third-party traffic to a country not on the list is an FCC rule violation regardless of how innocent the message content.
A third party may speak directly over your microphone as long as you, the licensed control operator, are present and in control throughout the contact. You may not leave the room and let the third party operate unsupervised. The moment you are no longer in control, the transmission becomes unauthorized.
Every amateur station must transmit its assigned call sign on each frequency it uses at the end of each communication and at least every ten minutes during a communication. The call sign must be transmitted in one of the following ways:
You may optionally add the identifier "stroke" followed by any self-assigned indicator (such as /portable or /mobile) to your callsign for informational purposes. Tactical call signs used in emergency operations do not satisfy the identification requirement — you must still give your FCC-assigned callsign at the required intervals.
If your station causes harmful interference to another station, you must stop operating on the offending frequency and take corrective action before resuming. This section reinforces the general principle that amateur operators are responsible for managing interference caused by their stations.
An amateur station must use the minimum transmitter power necessary to carry out the desired communications. This is §97.313(a) and it is a legal requirement, not a suggestion. The maximum power limits set elsewhere in Part 97 are ceilings, not targets.
Maximum power limits by band and license class are specified in §97.313(b) through (j). The key limits for General Class:
An auxiliary station is an amateur station that retransmits, automatically and without human intervention, the signals of other amateur stations. Auxiliary stations operate above 222 MHz. Any amateur licensee may be the control operator of an auxiliary station, but operation must comply with the automatic control rules.
A beacon station transmits one-way communications for the purposes of observation of propagation or related experiments. Beacons operate under automatic control and must transmit their callsign at least every ten minutes. Beacons are useful propagation tools — if you can hear a beacon from a distant location, you know that path is open.
A repeater automatically retransmits the signals of other amateur stations. Repeaters operate under automatic control. The repeater licensee is responsible for its proper operation. Repeaters may be operated on any frequency where it is legal to operate the amateur station, subject to coordination with other repeater operators in the area.
A space station is located more than 50 km above Earth. Any amateur licensee may be the telecommand (control) operator of a space station. Earth stations communicating with the International Space Station use the ISS club callsign NA1SS or the individual astronaut's personal callsign.
An Earth station is one that communicates with a space station. Any licensed amateur may operate an Earth station using the frequencies and power authorized for their license class.
Section 97.301 and its tables define the frequency bands authorized for amateur use and which license classes may use which portions. This is the regulatory source for everything in the frequency tables below. When you want to verify exactly what you are authorized to use, §97.301 and its associated tables are where you look.
Amateur operators must not cause harmful interference to, and must accept interference from, stations operating in accordance with the ITU Radio Regulations. On certain bands, amateur radio is a secondary allocation — meaning other services have priority. On 30 meters, for example, amateur radio is secondary to fixed services. On 60 meters, amateur radio is secondary to federal government operations. Understanding primary vs. secondary allocations explains why power limits and operating restrictions exist on certain bands.
This section defines which emission types (CW, phone, image, data, etc.) are authorized on each frequency band for each license class. Not all modes are permitted everywhere. On 60 meters, only specific emission types are authorized. On 30 meters, no phone is permitted. These restrictions come directly from §97.305.
Your transmitted signal must not cause spurious emissions that exceed the limits in this section. Harmonics, intermodulation products, and other spurious emissions must be suppressed. The general standard is that spurious emissions must be at least 43 dB below the peak power of the fundamental. This is why you need a low-pass filter on your HF transmitter output.
Amateur stations may transmit RTTY and data using any digital code whose technical characteristics are publicly documented. This is the rule that permits FT8, PSK31, VARA, and other modern digital modes — all of them use publicly documented, openly available protocols. It also reinforces the prohibition on encryption: if the code is not publicly documented, it is not permitted.
(Covered in Subpart B section above.)
External RF power amplifiers capable of operation below 144 MHz must be FCC-certified for use in the amateur service. You cannot legally use an uncertified amplifier below 144 MHz. This rule exists because high-power amplifiers can be modified to operate on frequencies outside the amateur bands; FCC certification requires that the amplifier design prevent such modification.
Before constructing an antenna structure, you must notify the FAA if the structure exceeds 200 feet above ground, or if it is located within certain distances of an airport. Structures requiring FAA notification must also be registered with the FCC. The FCC antenna structure registration database (ASR) is public and searchable. Failure to register a structure that requires registration is a separate violation from the antenna structure itself.
When normal communications are disrupted by a disaster, amateur stations may use any means of radiocommunication at their disposal to assist with disaster relief work. This is one of the broadest authorizations in Part 97 — it suspends many of the normal restrictions when genuine disaster relief is being conducted. However, this authorization is limited to actual disaster situations. It does not apply to drills, exercises, or training events.
No provision of Part 97 prevents the use of amateur radio in connection with the immediate safety of human life and the protection of property when normal communication systems are not available. This is the rule that allows you to transmit on any frequency in a genuine life-threatening emergency, regardless of your license class or the band's allocations.
Any amateur station in distress may use any means at its disposal to attract attention, make known its condition and location, and obtain assistance. If you hear a station in distress, you are authorized to take whatever action is necessary to assist them, including transmitting on frequencies outside your normal privileges.
The Radio Amateur Civil Emergency Service (RACES) is specifically authorized for communicating with civil defense organizations during periods of local, regional, or national civil emergency. RACES operation is distinct from normal amateur operation — when RACES is activated by civil authorities, RACES stations operate under specific rules that may differ from normal Part 97 operation.
Amateur radio licenses in the United States are examined and processed through the Volunteer Examiner (VE) system rather than by FCC staff. This system, established in 1984, uses licensed amateur operators to administer exams under the oversight of Volunteer Examiner Coordinators (VECs).
Key points from this subpart that appear on the General exam:
Your Technician license gave you full privileges on the VHF and UHF bands. On HF, Technicians have limited access: CW on 80, 40, 15, and 10 meters in small Novice subband segments, plus phone privileges only on 10 meters above 28.300 MHz. General Class changes everything below 30 MHz.
When you upgrade to General, you gain access to substantial portions of every HF band. Extra Class operators retain exclusive privileges in specific small segments at the bottom of each phone and CW band. You must know where those Extra-only segments are so you do not accidentally transmit in them.
Green rows show General Class privileges. Red rows show Extra-only segments you must avoid. Yellow rows show bands where General and Extra share full access (the WARC bands).

| 60m | 5 specific channels | USB phone, CW, limited digital | General & Extra | 100W ERP max. Secondary allocation. See below. |
The 60-meter allocation is unlike any other amateur band. It is not a continuous frequency range — it consists of five specific USB phone channels established by the FCC. You must operate on these specific center frequencies, which means operating with your transceiver's carrier frequency set 1.5 kHz below the channel frequency to place the USB signal on the channel. The five channels and their carrier frequencies:
| Channel | Center Frequency | Carrier Frequency (USB) |
|---|---|---|
| 1 | 5.332 MHz | 5.330.5 MHz |
| 2 | 5.348 MHz | 5.346.5 MHz |
| 3 | 5.358.5 MHz | 5.357 MHz |
| 4 | 5.373 MHz | 5.371.5 MHz |
| 5 | 5.405 MHz | 5.403.5 MHz |
Maximum power on 60 meters is 100 watts PEP effective radiated power (ERP) when using a half-wave dipole reference antenna. Permitted modes: USB phone, CW, RTTY, PSK31, and PACTOR III. FM, AM, and most other digital modes are not permitted on 60 meters. Amateur radio is secondary to federal government operations on this band.
The 60-meter channels are shared with federal government users, particularly for emergency and defense communications. These channels exist specifically because they propagate well for NVIS (near vertical incidence skywave) regional emergency communication — the same propagation mode covered in G3.
The 30, 17, and 12-meter bands were added to the amateur service at the 1979 World Administrative Radio Conference (WARC), which is why they are called WARC bands. They have two important characteristics that distinguish them from other amateur HF bands:
The control operator concept is straightforward in its legal definition but causes real confusion in practice. Here is how it works in situations you are likely to encounter.
Your home station, you operating: You are both the station licensee and the control operator. You are responsible for everything.
A friend (also a General) uses your station while you are present: Your friend is the control operator and responsible for their transmissions. You are still the station licensee and share responsibility. Your friend may only use frequencies authorized for their license class — they cannot operate on Extra-only segments at your station even though you are an Extra (if you were).
You allow a non-licensed person to speak on your station: You remain the control operator at all times. You must be present, in control, and listening. The non-licensed person is a third party. You identify with your callsign. If you walk away, the non-licensed person cannot legally continue operating.
You operate a remote station via the internet: You are the control operator. The rules apply as if you were physically at the station. You must have operating privileges for the frequencies being used. You must be capable of terminating transmissions immediately. The fact that the transmitter is 500 miles away does not relieve you of responsibility.
A club station operates at a field day event: Each operator who uses the club station during their operating period is the control operator during that period. The club is the station licensee. Each control operator is responsible for their own transmissions and may only operate within their own license class privileges.
The G1 subelement is divided into five sub-elements, each with its own set of pool questions. Every pool question in G1 is covered below, organized by sub-element. The material in Part 1 provides the context; this section provides the concise exam answers.
