The Samyung SRG-150DN is a high-performance 150W Class A MF/HF radio communication system engineered by Samyung ENC for commercial ships and fishing vessels operating in GMDSS sea areas A2, A3, and A4. Designed to provide long-range maritime voice communication, Digital Selective Calling (DSC), and NBDP (Narrow Band Direct Printing) capabilities, it offers clear signal reception and reliable transmission under harsh oceanic conditions.

Equipped with a high-contrast LCD display and an integrated 6-channel DSC watch-keeping receiver, the SRG-150DN complies fully with SOLAS and IMO GMDSS regulations. Its rugged, compact transceiver unit and outdoor automatic antenna tuner (ATU) deliver stable RF output, low maintenance requirements, and rapid frequency tuning across all marine MF/HF bands.

Key Features:
• Full GMDSS Compliance: Meets international IMO, ITU, and IEC standards for Class A MF/HF DSC radio stations.
• Integrated 6-Channel DSC Receiver: Continuously scans all maritime distress and safety frequencies for continuous watchkeeping.
• Clear Graphic LCD Display: Large backlit screen with customizable dimming controls for night-watch navigation.
• 150W Transmit Output Power: Delivers strong RF output and crisp audio clarity for long-distance oceanic communications.
• Automatic Antenna Tuner (ATU): Heavy-duty outdoor tuner rapidly matches antenna impedance for maximum transmit efficiency.
• One-Touch Distress Operation: Spring-loaded emergency distress button enables immediate alert activation while preventing accidental triggering.
