Ham radio, also known as amateur radio, has been around since the early days of communications, and it’s more common now than ever. According to the National Association for Amateur Radio (ARRL), there are 750,000 amateur radio users in the USA and 3 million worldwide. This number is growing by 1% on average per year.

As the trend picks up, more users are trying to make things easier and quicker by creating a Ham Lingo, also known as Ham Radio Slang. The number of words in the ham Radio jargon is growing by the day, but there are several main words that every ham radio enthusiast should master. It may seem like a daunting task, but it’s a piece of cake once you understand the basic terminology.

If you are new to this hobby and would like to better understand what is ham radio all about before getting into the ham radio lingo, feel free to check our other articles.

Q-Codes Used by Ham Radio Operators

Q-Codes or Q-Signals are a combination of three letters beginning with the letter “Q.” Hams use these instead of common sentences to make radio communications quick and efficient. There are dozens of Q codes, each with its meaning. A Q-code can take the form of a question when followed by a ‘question mark’ or a statement when it doesn’t have one.
We’ve compiled a list of the most common Q-codes you need to know to learn ham radio lingo basics and make things simple; here’s a quick rundown.


QRL is one of the most commonly used Q signals. You send a QRL before beginning a call to determine if a particular frequency is available for use. The amateur radio station wishing to use the frequency would send QRL, meaning “are you busy?” If the frequency is in use, the frequency station should send QRL, meaning “I am busy, please don’t interfere.”


Initially, a QSL was to acknowledge receipt of a formal message. Today, it denotes that you have received a transmission that can contain a formal or informal message. You can send a QSL in the form of a card, email, or even an audio recording. For example, QSL: I acknowledge receipt. QSL?: Can you acknowledge receipt?


If someone says, RIG HR IS QRP, they mean the transmitter’s power output is 5 W or less. Your transmitter output power must be 5 W or less to qualify for the QRP category. An example is: QRP (I will decrease power) or QRP? (Shall I reduce the transmitter power?).


This Q-signal was common among amateurs sending and receiving radiograms. They would use this Q-signal to notify the other operator that they had no messages or ask if they had any messages to pass. Today, you’ll sometimes hear stations say, I AM QRU, meaning that unless you have something further to say, they wish to end the radio communication. They probably also mean this if they send QRU. For instance, QRU: I have nothing for you, or QRU?: Do you have anything for me?


You can use this code to ask whether to send slower codes or as a statement to alert the other ham to send slower codes. When sending this code, it is only courteous to slow down.


Initially, this meant that a station was ready to copy a message. Nowadays, it shows that a station is ready to go on air or to ask if one is prepared to go on air. For example, QRV?: “Are you ready?” QRV: “I’m ready.


This code asks the other frequency whether it is okay to get off-air and states that you are about to get off the air. As a statement, it means “stop sending.” And as a question, “should I stop sending?”


QSO is used as a noun to mean a contact. For example, “I can communicate with QSO directly” or “can you communicate with QSO directly?”


QRZ is a Q code that a radio operator uses to ask “Who’s calling me?” or indicate that a particular person is calling. For instance, “QRZ [name]” means “You’re being called by [name].”


QTH stands for “My location is _____.” So, when you send QTH Florida, you tell the other operator that your location is in Florida. When followed by a question mark, the Q-signal turns into a question- QTH? Asks the question, “What is your location?”

Ham Radio Communication Terms

When checking into a repeater, amateur radio band, or listening to the ham radio band with a scanner, you will discover a lot of jargon. Here are some of them together with their meaning.


This term says “best regards” or “best wishes.” It’s a friendly way to end a conversation. You can use it when signing off or when you want to say goodbye.


This one is used to say “love and kisses.” It’s a bit more intimate than 73 and is common among close friends and family. While it’s not necessarily inappropriate to use it with strangers, it’s best to be cautious.


The “D” represents distance, and “X” means unknown. It means a far-away station that is hard to hear in a specific location and frequency. You can use it as a verb as DXing and say “I’m DX-ing today” or as an adjective and say, “that was a DX QSO.” A hobbyist who likes listening to far-away radio stations is called a DXer.


This Q-code is used to indicate that the communication is ending. Usually, one party will say “99,” and the other will respond with “73”. For example, you might say, “I have to go now, 99,” The other person would respond with “73”.


XYL is an abbreviation for ex-young lady, meaning a wife. For example, you can say, “I wanted to buy that new radio, but the XYL said it was too expensive.”


YL is an abbreviation for a young lady who is a licensed amateur radio operator. For instance, you can say, “The XL on 15 MHz was very kind and eloquent”.


Copy is a term that means “Understood.” It shows that one has understood the message sent to them. You can use it when you overhear and receive communications between two stations which is helpful for your station.

Ham Radio Operation Lingo For Beginners

Antenna impedance: This is the resistance in an electric current that flows off the alternating current of an antenna at its resonance. It fluctuates with the radiofrequency energy in operation, but most transceivers require it to be at 50 Ω.

Antenna matching: Ensuring that the antenna’s impedance at resonance is at optimum performance for your transmitter output circuit.

Bandwidth: It’s the width of an output frequency band; you obtain it by taking the highest frequency and subtracting the lowest frequency.

What Equipment Do You Need for a Ham Radio?


A transceiver is one of the most critical pieces of equipment on a ham radio since you can’t communicate without it. It’s a combination of a radio transmitter and a receiver. The types vary based on power and price, but the more watts the transceiver has, the better and the more expensive it is.


An antenna is another crucial element of your ham radio setup because it enables you to connect with other ham radio enthusiasts. Before purchasing one, check if your radio supports a single or dual-band antenna that operates on two separate bands or frequencies.

If your original antenna is not powerful enough, you can replace it with a better one. Ideally, your antenna should be a ¼ inch of the wavelength you plan to use. For example, a UHF 70 cm broadcast band will require a 7-inch antenna.

Power Source

It’s essential to have the right power source for your ham radio, such as generator, electricity, radio batteries, or solar panels. If you decide to use electricity, ensure that you have an alternative power source for emergencies.

Antenna Tuner

An antenna tuner or antenna tuning unit (ATU) is a gadget installed between an amateur radio transmitter and the antenna. When adjusted, it improves power transfer by matching the impedance of the radio to that of the antenna.


Repeaters are essential for some ham radios, such as the handheld ones, which only extend to a maximum of 2 miles. You can place the repeaters on a hill or a tall building with powerful antennas and equipment. They receive a nearby single and “repeat it” by broadcasting it to a more extensive network so the signal can travel further. With just one repeater, your signal can reach another 50 miles, and it could cross the country with more repeaters.

What Are the Available Types of Ham Radio Licenses?

Before understanding how to get the ham radio license, you need to decide which license is right for you. Check the short description of license types available.

Technician License

A technician license is an entry-level ham radio license and is the perfect option for beginners. To receive this license, you must pass a 35-question exam covering operating practices, regulations, and radio theory.

On passing the exam, you receive your license and gain access to amateur radio frequencies above 30 megahertz, which you can use to communicate locally and internationally on a small scale.

General License

A general license is an advanced technician license. You must pass the technician exam and take another 35-question exam to receive your general license.

This license will provide you with the same access as a technician’s license but gives you additional worldwide communications.

Amateur Extra License

The Amateur Extra license gives you all US amateur radio privileges on all amateur radio bands and modes. The licensing requirements are much more rigorous compared to technicians and general permits. After acquiring your General license, you must successfully pass an extra 50-question exam to get this license.

Ham Radio Compared to Other Personal Radio Services

In addition to the Amateur Radio Service, there are three other personal radio services that you can use for private communications. They are:

The Citizens Band Radio Service (CB)

CB is a two-way, short-distance voice communications service for personal and business. It operates on 40 channels between 26.965 MHz and 27.405 MHz, but transmitter power is limited to 4 W. You don’t need a license for this radio service; even so, your transmitters must be certified by the FCC.

The General Mobile Radio Service (GMRS)

GMRS is a short-distance, two-way voice communication service that operates on 30 channels on 462 and 467 MHz. You need a license to use this radio, and the output power can be up to 50 W.

The Family Radio Service (FRS)

Family radio service is a personal radio voice communication service that operates on 22 channels ranging between 462 and 467 MHz. No license is required to use this radio, but it’s limited to 2W output power.
