Module 5 - Routine Calls

Basic Calling Format

What you will learn

Prepare and deliver a brief routine voice opening that lets the called station recognise the call, identify your vessel and decide what should happen next.

A routine call is a short request for contact, not the whole conversation. Listen first, name the station being called, identify your own vessel, give only the useful purpose and leave space for the reply.

MCA small-craft guidance reduces a good transmission to disciplined choices: listen before transmitting, think through the message, be brief, identify the station clearly, wait for a reply and use low power first except for distress. Those habits protect a shared channel and make the call easier to answer.

For a voice call, say the called station name, then 'this is' and your own vessel identity. Repetition can help when reception is weak or the station may not yet be listening, but it is not a licence to occupy the channel with an automatic three-by-three formula for every routine exchange. Use only the repetition needed for reliable recognition.

The first transmission normally stops after the identity and concise purpose, followed by OVER because a reply is expected. Detailed berth requirements, passage history or a long operational message belongs after contact, usually on the station's published or agreed working channel.

Worked example

Example teaching script for a routine call on the harbour's published channel; the names are fictional.

  1. 1'Westhaven Harbour, Westhaven Harbour, this is sailing vessel North Star, North Star. OVER.'
  2. 2Release PTT and wait. Do not add the full request until the station answers.
  3. 3After the reply, give the concise position and request, then follow any channel or reporting instruction.

Sense check: The wording may vary with local procedure, but the identities, brevity and reply interval should remain clear.

Make the first transmission answerable

You need to call harbour control from outside the entrance. The current harbour guide gives its working channel and asks arriving yachts to report before entering.

  1. 1. Prepare

    Write down the station name, your vessel name, position and one-line request before pressing PTT.

  2. 2. Listen and call

    Confirm the published channel is clear, use low power first, call the station and identify your vessel.

  3. 3. Release and wait

    End with OVER, release PTT and leave a real interval for the station to answer.

Sense check: A listener hearing only the opening should know who is being called, who is calling and that a reply is expected.

Common mistake or limitation

  • Starting with a long story before the called station has acknowledged the call.
  • Omitting your own vessel identity because you assume the station can see you.
  • Holding PTT while waiting, which prevents the other station from replying.

Recap

  • Prepare the station, identity and purpose before transmitting.
  • Listen first, identify both sides and keep the opening brief.
  • Use OVER only when a reply is expected, then release PTT and wait.
