En parlant via la radio, il faut tenir compte de ce qui suit:

  • Parlez clairement, de façon à ce qu’il n’y ait pas de confusion possible ;
  • Parlez d’une voix normale, ne parlez pas trop haut car ceci pourrait surcharger le microphone et causer une déformation du son;
  • La voix devrait être mise sur une tonalité plus haute que pour une conversation normale et il faut éviter de descendre de tonalité à la fin d’un mot;
  • Parlez lentement mais en phrases plutôt que mot par mot.
Tous les appels (à l’exception des appels initiaux de Détresse, Urgence et Sécurité expliqués dans les chapitres suivants) par VHF RT se passent selon un même modèle.

Pattern used after the contact is established

All identifications could be used at the same time in a call, but in most cases just one of them is used.

Identifications are spoken:
  • 3 times in case of Distress, Urgency or Safety working, in difficult radio conditions, sailing at international or another country's water (because of the language-pronunciation problem).
  • twice in case the called station is not expecting the call,
  • once in all other cases.
But after the contact is established, any identification need only be transmited once.

VHF radio voice procedure:
  • Press the PTT switch and call (using the pattern above) ending with the procedure word “OVER”
  • Release the PTT switch and listen for a reply
  • When communication is completed finish with the procedure word “OUT”


Push the button to listen to an example of the correct voice procedure, which is exchanged between the sailing boat Spinaker and the Marina Koper. Please note the ON/OFF position of the black PTT switch during the communication exchange.

An example of the correct voice procedure, which is exchanged between the sailing boat Spinaker and the Marina Koper. The communication started on VHF CH 16 and after first contact Marina Koper gave a dedicated VHF CH 15 as a working channel on which the communication proceeded.

Garbled calls

When a station receives a call without being certain that it is intended for it, it must not reply. When a station receives a call, which is intended for it, but is uncertain of the calling station's identity, it should reply as follows:

Station calling Spinaker Station calling Spinaker

THIS IS Spinaker

Say again
