1.MAKING A CALL USING VOICE CALLING ON VHF

• Maintain your watch: Whenever your vessel is underway, the radio must be turned on and tuned to channel 16, except when being used for messages.
• Power: Try one watt first if the station being called is within a few miles. If there is no answer, you may switch to higher power.
• Calling Coast Stations: Call a coast station on its assigned channel. You may use channel 16 when you do not know the assigned channel.
• Calling Other Ships: Call other ships on channel 16. You may call on ship-to-ship channels when you know that the ship is listening on both a ship-to-ship channel and channel 16.

  NOTE: To do this, the ship must have two separate receivers.

• Limits on Calling: You must not call the same station for more than 30 seconds at a time. If you do not get a reply, wait at least two minutes before calling again. After three calling periods, wait at least 15 minutes before calling again.
• Change Channels: After contacting another station on channel 16, change immediately to a channel that is available for the type of message you want to send.
• Station Identification: Identify, in English, your station by your FCC call sign, ship name, state registration number, or official number at the beginning and end of each message.
