Fishing boat radio communication plays a decisive role in the safety of fishery production. The following are some basic common sense of fishing boat radio communication.
▲ Communication requirements for fishing vessels operating at sea:
1, must contact the unit (or family) 1-2 times a day;
2. Frequent liaison must be maintained between fishing vessels operating in common;
3. The communication equipment must be guaranteed to be turned on 24 hours a day and work 24/7.
▲ The type and frequency of maritime communication and its scope of application:
1. Short-wave single-sideband communication with a frequency range of 3 to 30 MHz, which is generally used for long-distance communication;
2.Ultra-short wave communication (marine handheld walkie-talkie, marine radio), frequency range is 30 ~ 300MHz, generally used for short-range communication.
▲ The frequency of international calls for help:
1. Short-wave communication frequency: 2182KHz;
2. Ultra-short wave communication frequency: 156.800MHz, 156.450MHz.
▲ How to send a distress signal in distress at sea:
No matter which communication tool you use, you should repeat the call every 1 minute on the frequency of normal use and the frequency of international maritime distress. The contents include: time of the distress, place (longitude, latitude), name of the ship, name of the captain, number of people in distress, and other contents that must be reported.
▲ The use of commonly used marine radio:
1.Select a channel for a call;
2. Dial the other's ship number for a call;
3. Accept the other party's dial-up call to this station;
4. Distress call for group calls;
5. Automatically receive a distress signal;
6. Receive a fishery group call signal;
7 Receiving the selective call signal of each station;
8. Storing into the common channel;
9. Taking out the common channel for calling;
10. Performing scanning reception of the common channel;
11. Performing scanning reception of the whole channel.
