T1: Commission's Rules

Let's start with the big picture: why ham radio is allowed to exist at all, who makes the rules, and a handful of important words you will see over and over for the rest of your studying.

Why does amateur radio exist?

Here is something neat: the rulebook actually writes down the reasons amateur radio is allowed. Think of it like the mission statement at the top of a club's handbook, a short list of "this is what we are here for." In the rules, that list of reasons is called the "Basis and Purpose" of the Amateur Radio Service. ("Basis" means the foundation it stands on; "Purpose" means the point of it.)

The one reason the test wants you to know by heart is this: amateur radio exists for advancing skills in the technical and communication phases of the radio art. Let's unpack that fancy sentence into kid-words. "Advancing skills" means getting better. "Technical phase" means the nuts-and-bolts side, how radios actually work. "Communication phase" means the talking side, getting good at reaching people over the air. "The radio art" just means the craft of doing radio. So the whole thing simply means: ham radio exists partly so people can learn how radio works and get good at talking over the air. It is about building skill and knowledge.

The test will tempt you with wrong answers. It is not a service whose job is to give every single citizen a personal phone line, and it is not there just for organized contests. Those sound official, but they are wrong. When in doubt, pick the answer about "getting better at the art of radio."

Who's in charge?

Somebody has to be the referee for everything that travels through the air on radio waves, or it would be chaos. In the United States, that referee is a government agency whose nickname is the FCC. That stands for the Federal Communications Commission. ("Federal" means it is part of the national government; "Communications" means anything that sends messages; a "Commission" is just a group put in charge of something.) The FCC both makes the rules and enforces them, the same way a referee both knows the rulebook and blows the whistle. They oversee TV, cell phones, broadcast radio stations, and yes, your ham radio.

Watch out for sneaky wrong answers. You will see the ARRL offered as a choice. The ARRL (the American Radio Relay League) is a wonderful national club that helps hams and speaks up for them, but it is not the government and it does not make the rules. You might also see Homeland Security or others. The referee for ham radio in the U.S. is always the FCC.

Two ways to talk: phone and CW

These two little words show up constantly, so let's nail them now:

• Phone = talking with your voice. It feels backwards, but in ham radio "phone" simply means a voice signal. When you hear "phone emission," picture someone speaking into a microphone. ("Emission" is just the rulebook's word for "a type of signal you send out.")
• CW = Morse code, the pattern of short and long beeps (dots and dashes). CW officially stands for "continuous wave," but you can just think "Morse code" every time you read CW.

The phonetic alphabet

Picture trying to spell your name to someone across a noisy gym. "Was that a B or a P or a T?" Over a crackly radio, single letters like B, D, P, and T smear together and get lost. So hams agreed on a special clear word for each letter: Alpha for A, Bravo for B, Charlie for C, Delta for D, and so on. This set of stand-in words is called the phonetic alphabet. ("Phonetic" means "by sound.") So instead of "my call sign starts with K-B," you would say "Kilo-Bravo," which nobody can mishear.

What do the rules say about it? Using the phonetic alphabet is encouraged when using phone (voice). Pay attention to that word "encouraged." It means the FCC thinks it is a great idea and wants you to do it, but it is not a strict, must-do law. Think of it like a sign that says "please use your turn signal", strongly suggested for everyone's safety, but you will not get a special ticket just for that alone.

Getting your license, and proving you have one

After you pass the test, how do you find out it is official, and what actually counts as proof? Two separate questions, two separate answers.

• How you are notified: you get an email from the FCC with a link to download your license grant. ("License grant" is just the official word for the license the FCC hands, or "grants," to you.) The FCC does not automatically mail you a fancy paper certificate anymore. The news arrives by email. Surprising, but true, so keep your email address current.
• What truly proves you have a license: your license must appear in the FCC's online database. A "database" is just a big searchable list kept on a computer. The FCC's list of every licensed ham is called the ULS, short for the Universal Licensing System. If your name and call sign show up in the ULS, you are real and official. The list is the truth.

Memory trick: the proof is not the email, and it is not a printout you made, it is "you are in the database." If you are in the list, you are licensed.

One thing that is always forbidden: interference

The single rudest, most against-the-rules thing you can do is to deliberately ruin someone else's signal. The rulebook bans willful or malicious interference. Let's translate. "Interference" means messing up another station's signal so they cannot be heard. "Willful" means doing it on purpose. "Malicious" means doing it to be mean. So deliberately wrecking someone else's conversation, like keying up your radio just to talk over them, is flatly prohibited. Do not do it, ever. (Accidental, brief interference happens to everyone and is a different thing; what is banned is doing it on purpose.)

Beacons: little lighthouses on the air

Imagine a lighthouse on a foggy coast. If you can see its light, you know the air between you and it is clear enough to see through. Radio has its own version of a lighthouse. A beacon is a station that automatically sends out a steady, repeating signal that just says, in effect, "I am here." Other hams listen for it: if they can hear the beacon, they know their radio can reach that far in that direction right now.

The kind you study here is the propagation beacon. ("Propagation" is a key word that simply means how far, and in what direction, radio waves travel. We will use it a lot.) The rules set aside a home for automatically controlled propagation beacons on the shortwave bands: they live on the 10-meter band, between 28.200 MHz and 28.300 MHz. (MHz, said "megahertz," is the unit we use to label a radio frequency, like a house number on the radio dial.)

What counts as a "space station"?

You might think a "space station" has to mean a giant orbiting laboratory with astronauts inside. In the rulebook it is much simpler and is based on one thing only: height. A space station is defined as an amateur station located more than 50 km (about 31 miles) above the surface of the Earth. That is the entire definition. It does not matter whether a person is aboard or whether it is a tiny satellite. The single dividing line is altitude: above 50 km = a space station.

Frequency Coordinators: the traffic planners

Imagine a city with lots of repeaters (we will fully explain repeaters in groups T1E and T1F; for now just picture "signal-boosting relay stations sitting up on towers"). If two nearby repeaters tried to use the very same frequency, they would clash and garble each other. So the community uses a friendly volunteer to hand out frequencies, like a parking-lot attendant waving each car into an open, non-overlapping spot.

• That volunteer is called a Volunteer Frequency Coordinator, and they are recognized by the local amateurs. Their job is to recommend which transmit and receive channels repeater and auxiliary stations should use so they do not interfere with one another. (You will meet "auxiliary stations" in group T1D; think "linking helper stations.")
• Who chooses this coordinator? Not the FCC. It is the amateur operators in the local or regional area whose own stations are eligible to be repeater or auxiliary stations. In plain words, the community of repeater owners picks its own coordinator. The people affected choose their own organizer.

RACES: hams helping in emergencies

Hams are famously helpful during disasters, when normal phones and internet may be down. One organized way they help has the name RACES, which stands for the Radio Amateur Civil Emergency Service. ("Civil" here means civilian, ordinary, non-military life; "civil emergency" means a community disaster like a flood, a tornado, or a big power outage.) It is a program where licensed hams provide communications for the government when an emergency strikes.

To be the control operator of a RACES station (the control operator is the person responsible at the controls, which you will learn all about in group T1E), having your normal ham license is not quite enough. You also need certification of current enrollment by a civil defense organization. Translated: you must have official proof that you are signed up, right now, with an emergency-management or civil-defense group. That makes sense, you have to actually be a member of the emergency team before you can operate its station.

This group answers two questions: where on the radio are you allowed to talk, and how loud (how much power) are you allowed to be? Let's begin with the most important idea in all of ham radio: bands.

What is a "band"?

Radio waves come in many different sizes, and we sort them into neat groups. Each group is called a band. Think of the whole range of radio waves as one enormous ruler, and a band as a labeled stretch of that ruler, like the way a highway has separate lanes, each meant for a certain kind of traffic. Now, why are bands named with measurements like "2 meters" or "70 centimeters"? Because we name each band after the rough length of its radio wave. So "the 2-meter band" holds radio waves that are about 2 meters long, and "70 centimeters" holds shorter waves about 70 centimeters long.

Good news: you do not need to understand wave lengths deeply for T1. You mostly just need to recognize which frequency number belongs to which band. Here are the landmarks the test loves. (Remember, MHz, "megahertz," is just the unit for labeling a spot on the radio dial.)

Band name	Helpful landmark
10 meters (a shortwave / HF band)	Technician voice lives at 28.300 to 28.500 MHz
6 meters (a VHF band)	52.525 MHz lives here
2 meters (a VHF band)	146.52 MHz lives here (the whole band runs 144.0 to 148.0 MHz)
70 centimeters (a UHF band)	420 to 450 MHz

Two facts the test asks you directly, word for word:

• 52.525 MHz is in the 6-meter band.
• 146.52 MHz is in the 2-meter band.

Memory trick: the number 146.52 starts with "14," and the 2-meter band is the "144 to 148" band, so 14-anything points you to 2 meters. A number in the low 50s (like 52.525) points you to 6 meters.

A quick vocabulary pit-stop, because these three letter-groups appear everywhere. HF means "high frequency," and confusingly these are actually the lower shortwave bands; their special trick is that they can bounce off the sky and travel very far, even around the world. VHF means "very high frequency" and UHF means "ultra high frequency." VHF and UHF waves usually travel more in a straight line, like a flashlight beam, which makes them great for local, around-town chatting.

What Technicians are allowed to do

You will start out as a Technician, the entry-level license. Here is the shape of your privileges: Technicians get all of the amateur VHF and UHF privileges (a huge amount of room to play locally), but only a limited slice of the shortwave (HF) bands. Here is exactly what to remember:

• Voice (phone) on shortwave: a Technician may use voice on HF in only one place, the 10-meter band, from 28.300 MHz to 28.500 MHz. So if the test asks "on which HF band(s) does a Technician have phone privileges?", the answer is the 10-meter band only, and the exact range is 28.300 to 28.500 MHz.
• Digital modes like FT8: a "digital mode" means your computer sends little coded tones instead of your voice, and the computer on the other end decodes them. FT8 is a wildly popular digital mode that can make contacts over huge distances even when signals are extremely weak. Technicians may use digital modes on 10 meters, 6 meters, AND 2 meters. So when the test lists several of those bands together, the correct answer is "all these choices are correct."
• SSB voice above 50 MHz: SSB ("single sideband") is just an efficient flavor of voice signal; you will learn it in detail later. The rule to know now: SSB phone may be used in at least some segment of every amateur band above 50 MHz. ("Segment" means a portion or stretch of a band.) So pick the answer that says you can use SSB in some part of all of those bands.

CW-only slivers at the bottom of bands

The very lowest edge of a couple of bands is reserved for Morse code (CW) only, a quiet little zone where voice is not allowed. The two to memorize are 50.0 to 50.1 MHz (the very bottom of the 6-meter band) and 144.0 to 144.1 MHz (the very bottom of the 2-meter band). Picture a "Morse code only, no talking" lane painted right at the start of each of those two bands.

Talking to the Space Station

Here is one of the coolest facts in the whole hobby: the International Space Station (ISS) carries ham radio gear, and astronauts sometimes get on the air and chat with regular hams down on the ground. Who is allowed to try this? Any U.S. amateur with a Technician class license or higher. You do not need a fancier license, and you do not need special permission from NASA. As a brand-new Technician, you already have everything you need to call the Space Station. (This is one reason the ISS contact happens on the VHF bands, where Technicians have full privileges.)

Sharing the airwaves: primary and secondary users

Some bands are not used by hams alone. We share certain bands with other, non-ham services (like some government or commercial users). When a band is shared, one group is named the primary user and the other is named the secondary user. The primary user gets first dibs, and the secondary user has to work around them.

In the band segments where the Amateur Radio Service is secondary, the rule is clear: U.S. amateurs may find non-amateur stations using those segments, and we must avoid interfering with them. Picture being a polite guest in someone else's house, you are welcome to be there, but you stay out of the way of the people who live there.

Why you should never sit right on the band edge

Every band has a top edge and a bottom edge, and your whole signal must stay inside those edges. If you set your radio to transmit exactly on an edge, part of your signal could spill out past the line, which is against the rules. The test asks why this happens, and the answer is "all of these," because there are three separate reasons:

• Every signal naturally has little side-pieces called sidebands that stick out slightly above and below the exact frequency you set. Sitting on the edge means those sidebands cross the line.
• Your radio's frequency display might be a touch miscalibrated, meaning slightly inaccurate, so you might really be a hair outside where the screen claims you are.
• A radio's frequency can drift a little, wander, especially as the electronics warm up. You could start in-band and slide out.

Because all three can happen, the correct answer is "all these choices are correct." Memory trick: stay a comfortable distance inside the band, the same way you would not stand right on the very edge of a cliff. Give yourself room.

How much power you can use

Radio power, how strong your signal is, is measured in watts. The exact way we measure it is called PEP, short for Peak Envelope Power. Without getting technical, PEP is a fair way to measure the strongest moments of your transmitted signal. You really just need the two numbers:

• In a Technician's shortwave (HF) band segments: the maximum is 200 watts PEP.
• Above 30 MHz (with a few specific exceptions): the maximum is 1500 watts PEP.

Memory trick: low bands, low power (200 watts). High bands, high power (1500 watts).

This group is the "paperwork" part of ham radio: the different kinds of licenses, what your call sign looks like, how long your license stays good, what to do when it is time to renew, and a couple of rules about talking to other countries and operating from a boat.

The three license levels

Today the FCC issues three classes (kinds) of amateur license, arranged from beginner to expert. Each higher class unlocks more privileges:

• Technician — the entry level, where everyone starts.
• General — the middle level, which unlocks lots more shortwave operating.
• Amateur Extra — the top level, with every privilege available.

You may also bump into older names like "Novice," "Advanced," or "Technician Plus." Those older classes still belong to people who earned them long ago, but the FCC no longer issues new ones. So when the test asks which license classes are currently issued, the answer is exactly Technician, General, and Amateur Extra.

Your call sign

A call sign is your unique on-air name, a short string of letters and numbers like KF9ABC. It is how everyone on the air knows who is talking, the way a license plate identifies a car. The FCC hands you one automatically when you get licensed.

• Vanity call signs: a "vanity" call sign is a special one you request on purpose, maybe your initials, or a short snappy one. The rule to know: any licensed amateur may request a vanity call sign. You do not have to be an Extra, and you do not have to be any particular class. Any licensed ham can ask.
• Technician call sign format (the rules call it "Group D"): a valid example is KF1XXX. That is one or two letters, then a single number, then three letters. (So patterns like "two letters, a number, three letters," for example KF1XXX, are the Technician-style format.) The shortest, fanciest call signs, like a "1-by-2" such as W1XX, are reserved for higher license classes. On the test, pick the choice that looks like KF1XXX.

How long does a license last, and renewing it?

Question	Answer
How long is a license good for? (its "term")	Ten (10) years
How early may you ask to renew it?	Up to 90 days before it expires
If it expires, how long do you have to fix it? (the "grace period")	Two (2) years
May you transmit during that grace period?	No. Wait until it is actually renewed

Two of those words deserve a closer look. The "term" is simply how long the license is valid, which is ten years. The "grace period" is the safety net: even after your license expires, you still have two years in which you can renew it without having to take the exam all over again. BUT, and this is the trap the test absolutely loves, during that grace period you are NOT allowed to get on the air. The two-year grace period only protects your right to renew without re-testing; it does not let you transmit. You must wait until the renewal is officially processed before you key up again. The expired license is just being held open for you, it is not active.

Memory trick: 10 years to use it, 90 days to renew early, 2 years of grace, but stay silent until the renewal goes through.

When can you first get on the air?

The exact moment you may legally transmit on a brand-new first license is as soon as your operator/station license grant appears in the FCC's license database. (That is the ULS database from group T1A, the official online list.) It is not the moment you finish the exam, and it is not when you receive a paper. It is when you show up in the official list. So after testing, you watch the database, and the day your call sign appears, you are good to go.

Keep the FCC able to reach you

The FCC needs a working way to contact you, and these days that means email. The rule comes with teeth: if the FCC cannot reach you by email, the penalty can be revocation of your station license or suspension of your operator license. ("Revocation" means it is taken away; "suspension" means it is put on hold.) So keep your email address up to date in the FCC's records. It is like a library that needs your current contact info, ignore their notices and you can lose your card.

Where the FCC is in charge, talking to other countries, and operating from a boat

• International conversations are allowed, but they must stay incidental to the purposes of the Amateur Radio Service, plus remarks of a personal character. In kid-words: you may chat about the hobby itself and exchange friendly, personal small talk. What you may not do is conduct business or broadcast to the public. Hobby talk and personal hellos, yes; deals and announcements, no.
• Out at sea (in international waters): you may operate from a U.S.-documented (registered) vessel, as long as the master gives permission. ("Documented vessel" means a boat officially registered in the U.S.; the "master" is the captain, the boss of the ship.) So you need the captain's okay before you operate from their boat.

This group draws the line between what you are allowed to send and what is off-limits. Hold onto one big idea, because nearly every rule here flows straight out of it: ham radio is a hobby for two-way conversation and learning, not a TV station and not a business. Keep that sentence in mind and most of these answers will feel obvious.

Countries you may not talk to

You are allowed to talk with hams in almost every country on Earth. The one exception: you may not communicate with a country whose government has officially told the ITU that it objects to such communications. ("ITU" stands for the International Telecommunication Union, a worldwide organization that helps countries cooperate and stay out of each other's way on radio, basically the global referee that the national referees like the FCC all coordinate with.) So if a country formally says "no thanks," you respect that. This rule blocks only the rare countries that opt out.

No broadcasting

First, the definition, because it is the key. For ham radio, the FCC defines broadcasting as transmissions intended for reception by the general public. In plain words, broadcasting means sending out programming meant for the public at large to listen to, exactly what a TV station or a commercial radio station does. That is their job, not ours, so on ham radio broadcasting is prohibited.

Now an important subtlety. A "one-way transmission" means you transmit but do not expect anyone to talk back. Some one-way transmissions are perfectly fine on ham radio, like sending Morse code practice, sending automatic equipment readings (called "telemetry"), or sending control signals to a model boat. So one-way transmissions are not banned across the board. The kind of one-way transmission that is prohibited is the broadcasting kind, transmitting to the general public.

No bad language

Keep it clean. Indecent or obscene language is prohibited, any such language at all. There is no official list of "forbidden words"; the rule simply bans indecent or obscene language in general. Speak the way you would in front of a teacher or a grandparent.

Secret codes: almost never

Ham radio is meant to be open and understandable, so you normally may not send a message in a secret code designed to hide what you mean. (The rules call this "messages encoded to obscure their meaning.") There is one narrow exception: it is permitted only when you are transmitting control commands to a space station or to a model craft (like steering a remote-control airplane). Outside of that, keep your messages in the clear so anyone can understand them.

Music: almost never

You normally cannot play music over ham radio. The single allowed situation is an unusual one: music is permitted only when it is incidental to an authorized retransmission of communications from a crewed (manned) spacecraft. Translated: if a station is officially relaying communications from astronauts, and a bit of music happens to come along with that, that specific case is allowed. For everyday operating, the answer is simply "no music."

Selling equipment, and getting paid

• You may use the air to let other hams know about gear for sale or trade, but with two limits: it must be amateur radio equipment, and it must not be a regular business. Mentioning that you are selling your old radio now and then is fine; running a constant on-air store is not.
• Operators generally may not be paid to operate a station. The one exception the test wants you to know: a control operator may receive compensation when the communication is part of classroom instruction at an educational institution. Picture a teacher whose actual job includes running the school's ham station during a class, that paid situation is allowed.

Helping news or broadcasting, but only for safety

May hams ever assist a news crew or a broadcaster? Only in a true emergency. It is allowed only when the communications are directly related to the immediate safety of human life or the protection of property, and only when no other method is available. So during a genuine life-or-property emergency, yes; just to help produce a TV show or gather news for entertainment, no.

A new word: the auxiliary station

An auxiliary station is a helper station whose job is to link parts of a larger system together. ("Auxiliary" just means "extra helper.") The classic example, and the one the test uses, is a station that sends one-way transmissions between a remote repeater receiver and the main repeater transmitter, essentially a wireless relay wire connecting two pieces of a repeater system that sit in different places. Just remember: auxiliary station = a linking helper station.

When you may skip identifying, and when you may not

• Normally you must always send your call sign (the full rules for that are in group T1F). The single time you are not required to identify is when you are transmitting signals to control model craft (such as an RC plane or boat). It is a tiny, easy-to-remember exception.
• What about when you are just testing your radio on the air? You still must identify the transmitting station with your call sign. "I'm just testing" is never an excuse to be anonymous.

Every single thing your station sends out over the air is somebody's responsibility. That somebody has a name: the control operator. This whole group is about that person, what they do, who picks them, and where they sit while doing the job.

What is a control operator?

A control operator is the licensed amateur who has been designated by the licensee of a station to be responsible for the station's transmissions and for keeping it in compliance with the FCC rules. ("Designated" means officially chosen; "the licensee" is the person whose license the station belongs to; "compliance" means following the rules.) Think of the control operator as the designated driver of the radio: whoever holds that role is the one accountable for keeping everything legal while the station is on the air.

Who picks the control operator?

The station licensee is the one who designates (officially chooses) the control operator. The owner of the station decides who is "driving." (Often the owner and the control operator are the same person, but they do not have to be.)

You can never operate without one

How often may a station transmit with no control operator at all? Never. There must always be a responsible control operator, even for a station that runs by itself like an automatic repeater, someone is still the responsible control operator even though they are not sitting there every second.

Here is an important pairing the test asks about. When the control operator is a different person from the station's owner, who is responsible for the station operating properly? Both of them, the control operator AND the station licensee. Two names are on the hook, not one.

Your license decides what frequencies you can use

This is one of the most important ideas in the whole test. The frequencies a station is allowed to transmit on are set by the class of operator license held by the control operator at that moment. It does not matter who owns the radio, who built it, or who else happens to be in the room, what matters is the license class of whoever is the control operator right now.

• So a Technician may NOT be the control operator on an Amateur Extra-only part of a band, at any time (the only exception being a genuine emergency), even if an Extra-class friend invited them and is sitting right there. You only get to use the privileges that your own license grants you.
• For satellites and space stations, the control operator may be any amateur who is allowed to transmit on that satellite's uplink frequency. ("Uplink" is the frequency you transmit up to the satellite.) So if a satellite's uplink sits in a part of the band that Technicians may use, a Technician is allowed to be the control operator working that satellite.

The control point

The control point is simply the location at which the control operator performs the control operator function. In plain words, it is the spot where the operator sits to run the station. Notice it is about where the operator is, not where the antenna or the transmitter happens to be. If you are running your station from the desk in your bedroom, then your desk is the control point, even if the antenna is out on the roof.

Three ways to control a station

Type	What it means	Example the test uses
Local control	You are right there, hands on the radio	Sitting at your radio in your room
Remote control	You run the station from far away through some link	Operating the station over the internet
Automatic control	No operator works the controls every second; the station runs itself within the rules	Repeater operation

Two facts to lock in from that table: the test's example of remote control is "operating the station over the internet," and the test's example of automatic control is "repeater operation."

One more handy fact: which stations are allowed to be remotely controlled? The answer is simply any station. Remote control is not limited to repeaters or to special gear, any amateur station may be set up for remote control.

This final group of T1 covers how to identify yourself correctly, how repeaters work and who is responsible for them, passing messages on behalf of other people, getting a club license, and the FCC's right to inspect your station.

Saying your call sign (identifying)

"Identifying" just means announcing your call sign so everyone listening knows who is transmitting. Here are the rules:

• How often: you must transmit your assigned call sign at least every 10 minutes during a communication, and once again at the end of it. So during a long chat, drop your call sign about every ten minutes, and give it one final time when you sign off.
• This stays true even if you are using a tactical call sign like "Race Headquarters" during an event. (A "tactical call sign" is a temporary nickname for a role or location, very handy for coordinating a public event, but it does not replace your real FCC call sign.) Even while using a tactical name, you must still give your real assigned call sign at least every 10 minutes and at the end.
• What language: on voice (phone), you must identify in English.
• What method: a station sending phone signals may send its call sign for identification using either a CW (Morse code) or a phone (voice) emission. Those are the accepted ways, voice or Morse, not some other random code.
• Self-assigned add-ons: you may tack a little indicator onto your call sign, and several ways of saying the slash mark are all fine. Saying your call followed by "stroke W3," or "slant W3," or "slash W3" are all acceptable. The words "stroke," "slant," and "slash" all just mean the little "/" mark, so all of those choices are correct.

Memory trick for identifying: "Every 10, and at the end, in English." Say it a few times and it sticks.

Repeaters

A repeater is a station, usually mounted up high on a tower, hilltop, or tall building, that listens on one frequency and at the same time re-sends what it hears on a different frequency. This stretches your range dramatically: your little handheld radio only has to reach the tall, well-placed repeater, and then the repeater re-broadcasts your words far and wide. So the type of amateur station that simultaneously retransmits the signal of another station on a different channel is a repeater station.

Now a responsibility question. Suppose a repeater accidentally passes along something that breaks the rules, say, somebody said something indecent and the repeater dutifully relayed it. Who is accountable? The control operator of the originating station, the person who actually said the bad thing in the first place, not the repeater's owner. You are always responsible for your own words.

Third-party communications

Sometimes you pass along a message for someone who is not a licensed ham, maybe a non-ham friend wants to say hello to a distant station through your radio. This is called a third-party communication. (You and the operator of the other station are the first two parties; the non-ham person whose message is being relayed is the "third party.")

• Definition to know: third-party communication is a message from the control operator of one station to the control operator of another station, sent on behalf of another person.
• The foreign-country rule: when a non-licensed person speaks to a foreign amateur station through a station that an FCC-licensed ham is controlling, it is only allowed if the foreign station is in a country with which the U.S. has a third-party agreement. A "third-party agreement" is just a standing deal between two countries that says "we will permit our hams to relay messages for non-hams to each other." No agreement with that country means no relaying non-hams' messages there.

Club stations

A group of hams can obtain a club station license, a license for the club itself, complete with its own club call sign. The requirement the test wants: a club must have at least four (4) members for a club station license grant to be issued. Four is the magic number.

FCC inspections

The FCC has the right to look at your station and your station records. When? At any time, upon request by an FCC representative. They do not need a search warrant or advance written notice. Agreeing to this is simply part of the deal of holding a license. (In real life, an inspection is very rare, but the rule is the rule, so know it.)
