▲ 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.

6. Receive a fishery group call signal; 

7 Receiving the selective call signal of each station;
