Fill in your own details and hear the contact you are about to have. Five transmissions, start to finish.

    A real contact alternates between two stations; what you see here is the whole shape with your own details in it. The wording is the same worldwide - CW is worked with English abbreviations whatever language you speak.

    Reading about a contact and hearing one are different things. The tool above builds the standard exchange from your own callsign, name and station - so what you practice is what you will actually send, not an example with someone else's data in it.

    Listen to it as a whole

    Play the entire contact once at a speed you can follow, and pay attention to the pauses: one and a half seconds between transmissions, because that is how long the other operator needs to switch from listening to sending. Without those gaps it sounds like one long announcement, which is exactly the mistake beginners make when they finally get on the air.

    Then play it again a little faster. The words stop being letters and start being shapes - and that is the moment Morse begins to work.

    What to change first

    • Your callsign. Put in your own if you have one, or leave the example. Listen to it until you recognize it instantly - your own call is the one thing you must never miss.
    • The speed. Start at a speed where you can follow the whole thing, not the speed you would like to reach.
    • The report. Try 339 instead of 599 and hear the difference; most beginners never send anything but 599 and never learn how the other digits sound.

    The share button puts everything into the link, after the hash. That part never reaches a server, so a club can pass a prepared contact around without anything being stored anywhere.

    Then do it for real

    When the shape sits, the remaining step is smaller than it looks. Listen on the air first - find a slow contact, follow it with the phrasebook next to you, and you will recognize every part of it. Then answer someone's CQ at a speed you can handle, send exactly what is here, and accept that the first one will feel like jumping into cold water.

    Everyone's first contact goes badly. That is not a reason to delay it; it is the reason to get it over with.
