Voice Calling

VHF Marine Radio Protocols

Voice calling

•

To call another vessel or a shore installation such as a lock or bridge tender:

■Make sure your radio is On.

■Select Channel 16 and listen to make sure it is not being used.

NOTE

Channel 9 may be used by recreational vessels for general-purpose calling. This frequency should be used whenever possible to relieve congestion on Channel 16.

■When the channel is quiet, press the Talk button and call the ship you wish to call. (Hold the microphone a few inches from your face and speak directly into it in a normal tone of voice — clearly and distinctly.) Say “[name of station being called] THIS IS [your vessel’s name or call sign].”

■Once contact is made on the calling channel, you must switch to

a proper working channel. See the channel listing on pages 14 through 15.

For Example

The vessel Corsair calling the vessel Vagabond:

Corsair: “Vagabond, this is Corsair.”

Vagabond: “Corsair, this is Vagabond. Reply 72 (or any proper working channel).”

Corsair: “72” or “Roger”

■After communications are completed, each vessel must sign off with its call sign or vessel name and switch to Channel 16.

NOTE

For best sound quality at the station you are calling, hold the microphone

on the front of the radio at least two (2) inches [five (5) cm] from your mouth and slightly off to one (1) side. Speak in a normal tone of voice.

Radiotelephone Calls

VHF Marine Radio Protocols

Radiotelephone calls

•

Boaters may make and receive radiotelephone calls to and from any number on the telephone network by using the services of public coast stations. Calls can be made

—for a fee — between your radio and telephones on land, sea, and in the air. See pages 14 through 23 for the public correspondence (marine operator) channels.

If you plan to use these services, consider registering with the operator of the public coast station that you plan to work through. Those services can provide you with detailed information and procedures to follow.

CAUTION

You may disclose privileged information during a radiotelephone call. Keep in mind that your transmission is NOT private, as it is on a regular telephone. Both sides of the conversation are being broadcast and can be heard by anyone who has a radio and tunes to the channel you are using.
