The Samyung SRG-3150DN is a 150-Watt MF/HF radiotelephone system manufactured by Samyung ENC Co., Ltd. in South Korea. Designed for full compliance with IMO, ITU, and GMDSS carriage requirements on SOLAS merchant ships and commercial fishing vessels, the system provides long-range voice communications, Digital Selective Calling (DSC), and Narrow Band Direct Printing (NBDP/Telex) functionality.

The SRG-3150DN integrates a 10Hz step digital synthesizer for stable frequency control and reduced noise. Built with an integrated 6-channel DSC watchkeeping receiver, the transceiver continuously monitors all maritime distress/safety frequencies. Paired with the SN-100 terminal screen, keyboard, and printer, the system forms a complete GMDSS station for ocean-going vessels operating in Sea Areas A2, A3, and A4.

Key Features:
