What kind of walkie-talkie is suitable for maritime communication? Sep 07, 2022

With the vigorous development of maritime industry, the importance of marine radio communication has also been paid more and more attention. Some people may have less exposure to this area, but to give you a few examples, such as the rescue of the Titanic, the rescue of the Jiang Yalun, etc., marine radio communication has played a crucial role. Today we are going to talk about this topic.

1. What is marine radio communication?

It is the main communication method between ship and ship, ship and shore, ship and aircraft, and inside the ship. Whether the radio communication order management is in place is directly related to the safety of life and property of sea personnel and maritime traffic safety. For example, the maritime distress and safety frequency VHF 16 is a dedicated frequency for maritime international distress and safety communications. It is used for distress calls and distress communications. It is an indispensable prerequisite for ship safety and distress rescue. It is called "Maritime 110".

2. Types of maritime communication, frequency division and scope of use

Marine radio, radio equipment installed on board a ship for communication purposes. Depending on the size of the vessel and its purpose, the functions and main properties of the radio vary. Small passenger ships sailing along the coast only need to be fitted with communication radios suitable for shorter distances, while smaller vessels used for recreational purposes, such as sailing, water sports etc., can carry portable handheld radios, while large passenger and cargo ships sailing on the high seas need to be equipped with long distance radios.

VHF communication radios: These include handheld radios and marine radios, with a frequency range of 30-300MHz, generally used for close range communication.

SSB communication radio: generally only available on board, frequency range 3-30MHz, generally used for long distance communication.

3. Common radio functions

Simplex handheld radio; duplex handheld-slipway intercom; distress group call; common communication channels; one-key alarm for help; channel scanning

4. Communication requirements for fishing vessels

Can not occupy CH16 communication resources for a long time; can not send Distress distress signal at will; must monitor the CH16 channel; must ensure the normal operation of the equipment; often contact the shore
