Marine Radio

From the communication service aspects, marine radio can be divided into public digital radio, the police radio, aviation radio, marine radio.

Marine radio, which is specially used for the communication on maritime navigation, is also called ship radio. Marine radio is particularly strong in profession, which can adapt to the harsh environment, wide range ship activity, large temperature vibration and the needs of global maritime safe navigation. The design of marine radio is very professional, and the working frequency is uniform. In accordance with the unified provisions of the international maritime communications, marine radio operating frequency TX ranges from 156.025MHz to 157.425MHz, RX ranging from 156.025MHz to 163.275MHz. Channel is divided into international channels, the United States channels, Canada channels, and 10 weather channels. The three kind of working channel is the standard of the three channels, each kind of marine radio is equipped with three standard versions. Users, according to the requirements of use, need to choose the different frequency while purchasing the marine radio. Some marine radio, in addition to the above frequency point, also kept 10 frequency points, which can be defined by the users themselves. It is easy for users to use within themselves. There are same frequency points different frequency points in marine radio. 

In order to meet the marine communication requirements, the structure design of marine radio should take the following factors fully into consideration, such as waterproof, anti salt fog, anti solar radiation and other factors. Excellent water resistance is the main indicator of marine radio. Some marine radio, also equipped with good and waterproof speaker, microphone battery. What’s more, good heat dissipation of marine radio is also a guarantee of long-term reliable work. In order to facilitate the operation, the marine radio panel control buttons and knob are not only with small number, but also have relatively large volume. The display is large, and the character display is clear, intuitive. Generally, marine radio’s function is relatively simple, practical, only to retain its original function. Excellent water resistance, salt fog resistance, strong and durable, high reliability, much working frequency are the characteristics of the machine radio. In accordance with the relevant provisions, the use right of marine radio on the ship must obtain the China Classification Society issued the "Certificate of Approval for Marine Products of China Classification Society". In addition, according to the provisions of the global maritime safety and security system standards (GMDSS). Ships sailing on the sea must be equipped with marine radio, which is based on the GMDSS standards, the quantity of marine radio according to the tonnage of the ship. The main purpose is to ensure the ship in emergency situations to be contacted. The marine radio, according to the GMDSS standards for the production, is orange, and the battery is lithium, which can support eight hours, to meet the requirements in the maritime distress for a long time work.
