Shipborne MF & HF DSC Radio Device
Shipborne MF&HF DSC radio device enables distress alerting, ship-to-ship and ship-to-shore communications, and enhances safety at sea by providing automated, selective calling capabilities through MF or HF bands. This device supports a wide range of frequencies for reliable long-distance communication, ensuring ships can maintain contact in various conditions and over vast distances.
Overview
Technical description
Large screen,single-key single use,intuitive display and easy operation.
Built-in 25 domestic shore station channels, which can freely switch user channels, ITU international channels and fishery shore station modes.
Daily voice calls, compatible with other ordinary shortwave radio stations, providing SSB/AM/CW/FSK/AFSK operation modes.
Support selective call,group call,sea call,all call and other digital selective calls.
Send and receive distress alarms, and automatically print the received distress messages.
Rolling, manual, timing, ship position report, built-in GPS module.
Quickly, automatically and manually perform antenna tuning.
Audio recognition squelch control.
