What are the marine channels?

The most important channels on your VHF radio are 13, 16, 19, 22, and 70. Channel 13 is used by commercial shipping to communicate their actions and confirm passage. Channel 16 (156.8 MHz) VHF-FM is designated by the FCC (Federal Communications Commission) as the national distress, safety and calling frequency.

What VHF channel can I use?

What channels should you use for regular conversations? Channels 68, 69, 71, 72, and 78A are considered non-commercial channels, and in most areas, 68 and 72 are commonly used by the recreational-boating community. But remember that the VHF is officially for “operational” purposes.

Public Safety Spectrum

How is Channel 70 used?

Channel 70 is used to send distress alerts, safety announcements and for calling purposes under the Global Maritime Distress and Safety System (GMDSS). Many vessels are now equipped with DSC capability and are using channel 70 for this purpose. It is essential that this channel be protected.

What channel is ship to ship?

Channel 06 – Ship-to-ship safety messages, and communication with search and rescue and Coast Guard vessels and aircraft. Channel 13 and Channel 67 – These are navigational channels. Channel 13 (all vessels) is for one watt of transmission power only.

What VHF channel should I use?

What MHz are TV channels?

470 MHz to
The TV frequency ranges for TV Channels The UK uses UHF channels 21-68 covering 470 MHz to 860 MHz. These TV channels are each 8Mhz wide. The formula to calculate the frequency is: Frequency (MHz) = 303.25 + ( 8 x Channel Number ).

What kind of radio does a ship use?

Marine VHF radio is one of the fundamental equipment for communication on commercial ships and watercraft. It is important and reliable for bidirectional voice communication both for ship-to-ship and ship-to-shore. To get stronger service, you should know the Marine VHF radio frequency range.

What kind of frequencies are used on ships?

A number of frequencies are duplex (split frequency) for ship to shore use, and where used for making telephone calls via shore stations. Although these duplex channels still exist for making telephone calls, today there are very few if any shore stations providing such a service.

Are there any shore stations that use HF simplex?

Although these duplex channels still exist for making telephone calls, today there are very few if any shore stations providing such a service. There are a number of HF simplex channels which can be used for either ship to shore or ship to ship communications.
