Calling CQ is a general invitation: "Is anyone out there who would like to talk?" It is one of the most satisfying things to do on the air, and one of the easiest to do badly. The best CQs differ from mode to mode, but they share a few habits: listen first, keep it short, and leave room to hear the answer.
Why a good CQ matters
A poor CQ wastes your time and other people's band space. A long, rambling call on an occupied frequency annoys neighbours, and one that never pauses gives nobody the chance to reply. A short, clear CQ on a clean frequency is easier to hear and easier to answer. That is the whole secret, and no mode changes it.
Transmitting requires the correct licence for the band and mode you are using. Canada and the USA differ in privileges, band edges and rules, so check the regulations for your own licence class before you call.
Listen before you transmit
Spend a few minutes listening on the band you plan to use. Are stations coming through, or is it empty? An empty band may be closed, not free. The live HF propagation page gives a good idea of which bands are likely to be open before you touch the transmit button. Our guide to reading a propagation forecast explains the numbers.
If you are new to the sound of the bands, you can hear real stations on the live operators page.
Find a clear frequency and ask first
Stay inside the segments your licence allows for the mode you are using. Then tune to a spot with no signals nearby and ask whether it is in use. Weak stations can be hidden under a strong one, so ask even if it sounds empty. If someone answers that it is busy, thank them and move on. A frequency is not yours because you got there first, but common courtesy says you should not sit on top of an ongoing conversation.
Calling CQ on phone
On voice, clarity matters more than volume. Ask if the frequency is in use, wait, ask once more, then call.
- Say "CQ" a few times, then your call sign once or twice using standard phonetics, spoken slowly.
- Say something like "calling CQ and listening", then release the key and actually listen.
- Keep the whole call to around ten or fifteen seconds. Repeating the sequence a few times is better than one long transmission.
- Use the sideband customary for the band: lower sideband below 10 MHz and upper sideband above it, with the usual exception of upper sideband on 60 metres.
Repeating your call sign in phonetics is what lets a distant station copy it. If you need practice, see our article on practical phonetics. Avoid excessive audio processing and never run more power than you need, since both spread your signal and muddy it for the listener.
Calling CQ on CW
CW rewards economy. Before calling, send QRL? (is this frequency in use?) and listen for a reply. The conventional format is "CQ" repeated a few times, then DE, then your call sign a few times, then K to say you are listening for anyone.
- Send at a speed you can comfortably copy back. Someone who answers may reply at your speed.
- Repeat your call sign so it survives noise and fading.
- Stop and listen after each round. Tune a little either side of your frequency, since replies are often slightly off.
- If the other operator is slower, QRS is the polite request to send more slowly.
Calling CQ on digital modes
With FT8 and FT4, your software builds the CQ for you, usually including your call sign and grid locator. Your job is to choose a good spot and to get your computer clock right, because these modes depend on accurate timing. Our guide to syncing your PC clock covers this, and FT8 for beginners walks through a first contact.
- Pick a gap in the waterfall away from other signals, rather than the busiest part of the passband.
- Keep your audio drive low enough that no ALC action shows. Over-driving creates splatter that spoils other people's decodes.
- Calling stations transmit in the opposite time slot to you, so avoid a slot already crowded with signals.
- Do not call CQ endlessly. If no one answers after several cycles, change frequency or slot, or try another band.
Many digital programs can report your signal to public reception-map services, which shows where you are being heard without anyone answering. That is useful feedback for a quiet band. For keyboard modes such as RTTY and PSK31, keep your CQ macro short, in the same spirit as CW.
Directed and special CQs
Some CQs are aimed at particular stations. A CQ for distant stations tells people you want contacts far from home, so do not use it if you would rather talk to a neighbour. A CQ with a contest word is meant for contests, and outside one it only confuses listeners. Activators in outdoor programmes commonly use a CQ that names the programme, but only use it if you really are activating. Answering someone's CQ when they did not ask for you is bad manners; answering when you fit their request is exactly right.
Common mistakes
- Not listening first. This is the number one cause of interference.
- Calling on an occupied frequency because it seemed quiet at that moment.
- Calling too long. A five-minute CQ leaves no time to hear a reply.
- Rushing your call sign. It is the one thing the other station must get right.
- Too much power or audio. Wider, louder signals are not more readable.
- Ignoring the band. Calling a closed band produces silence, not replies.
Stay safe too: keep antennas away from people, and follow the RF exposure guidance in your country, especially with higher power or an antenna close to the house.
A quick checklist before you press the key
- Your licence covers this band, mode and power level.
- You have listened for a few minutes.
- You asked whether the frequency is in use, and nobody answered.
- Your power and audio levels are modest and clean.
- You know how you will send your call sign clearly.
- Your logbook is open and ready.

After the contact
When a station answers, exchange the basics, confirm each other's details and log the contact straight away while it is fresh. The free online logbook keeps your contacts organised and exports to ADIF, and you can turn any contact into a shareable QSO card afterwards. Our walkthrough on making your first HF contact covers the full exchange.
Wrap-up
Whether you use your voice, a key or a keyboard, the formula stays the same: check conditions, find a clear spot, ask, call briefly, and listen properly. Do that consistently and you will spend less time calling into the void and more time in conversation. No approach guarantees replies, since propagation and timing always play a part, but a courteous, well-formed CQ gives you the best chance.
