Ham Radio Q Signals

Q signals are a common framework of Ham radio communication abbreviations that quickly provide terminology for useful procedural airwaves activity.

QRG This is used to ask another operator “What is the exact frequency you are using?

QRL Asked to find out if a frequency is busy. You can remember this one because “R” is for Receive and “L” is for Listen. Just think, “Is it OK to receive and I’m listening for traffic.”

QRM This is generally used when either you or your contact are experiencing interference. I remember this signal by thinking “Real Mess”. After stating QRM you also provide a 1 through 5 number indicating the severity of the interference – 1 is less and 5 is extreme. “It’s QRM at 3”.

QRN Used to communicate a problem with static. I remember the RN as “Really bad Noise”. Once again it is a 1-5 scale.

QRO Release more output. Increase the power of the transmission.

QRP Reduce power. Dial it down.

QRQ This signal is for speeding up data and CW (Morse Code) transmissions. Speed it up. Q is for quick.

QRS Same as above but the S is for “Slow”. Reduce speed of transmission.

QRT Stop. Don’t send. Stop sending.

QRU The U is for “You”. I have nothing to communicate to you or for you at this time.

QRV I remember the V in this as “Vacation”. Like…are you Ready? Although it has nothing to do with vacation just think of something you would like to do and ask, “QRV? Are you Ready?”

QRX This is a scheduling code. When are you or I available at the next time and frequency for another communication?

QRZ Indication of someone calling me or I them. “Callsign” QRZ available at such and such a frequency.”

QSB “Signal fading”. Remember this one with Signal Barely audible.

QSK When two contacts are transmitting and someone else wants to break in this is used to communicate, “Yes I hear you. Break in.”

QSL This one acknowledges receipt of the transmission and information or whatever is sent. It communicates that I have received what you have sent and asks if you have received what I have sent.

QSO Open or direct communication is indicated or asked. “Can you reach directly or via relay with so and so (callsign)?”

QSP This is Relay only.

QST The main Q Signal used for a transmission to all amateur radio operators. Usually used before transmission on a Net. Used to convey group information.

QSX Easily remembered by the word “SeX”. It doesn’t mean that but you have to remember these however you can. It means, “I am listening to so and so (callsign) on such and such a frequency”.

QSY Switch frequencies or “Let’s meet on a different frequency at (specify)”.

QTC Defines a specific or number of messages that I have for you or you have for me that are waiting and ready to deliver.

QTH Location. “I am located (here, there, at this frequency) and where are you?”

QTR Time. “The current time is?” “What is the correct time?”
