The ship shortwave communication system refers to a system that uses the original fishery shortwave frequency points to notify the fishing boats in the jurisdiction of weather, tidal floods, typhoons and other information, and publishes fishery safety production notices and other broadcast information systems.

Overview of system functions

The ship shortwave communication system is mainly composed of the shore station radio station (WT-B150), the ship radio station (WT-6000 or WT-B150) and the control system.

The control system controls the shore station station through the network, so that it can send all kinds of information to the ship anytime and anywhere, thus realizing the efficiency and convenience of information transmission.

Functions of the system monitoring platform

Antenna tuning: If the tuning antenna is selected, it is allowed to control the tuner to complete the tuning, display the tuned standing wave ratio, and display the transmitted standing wave in real time

Control of channel gain: The signal gain can be controlled through the panel. There are three specific signals: direct (default), amplification, and attenuation

Volume adjustment: adjust the output volume of the speaker

Squelch: configure the squelch threshold and turn on/off the squelch function through the panel or other methods

Support external speakers

Transmitting power: select high, medium and low transmitting power on the panel

Received signal strength display: display the strength of received signal and transmit power in real time on the panel

Local information: display of radio model, firmware version, working voltage, current and other parameters

Scan function: support two scanning methods-1. Scan preset channels; 2. Frequency scan function: can scan frequency according to the set start frequency, stop frequency and frequency step

Real-time location information: Receive standard NMEA data provided by external GPS and display the real-time location information of the station

Alarm and rescue: Receiving and displaying highly sensitive DSC information in compliance with the international GMDSS standard; one-key panel sending of distress signals; 6 standard channel scanning duty

Preset channel method: preset all ITU channels by editing and storing 200 custom channels; channel parameters include transceiver frequency, working mode, transmission power, etc.; normal communication can be achieved by selecting the channel number on the panel

The brightness of the display is adjustable

Support automatic switching of internal and external GPS signals

Support remote software upgrade and information transmission

Support encrypted communication mode
