The Icom GM800 is a high-performance commercial GMDSS Class A MF/HF marine transceiver manufactured by Icom Inc. in Japan. Engineered to meet strict SOLAS safety mandates for international commercial shipping, the GM800 provides reliable long-range distress, urgency, safety, and routine voice/DSC communications across the 1.6 MHz to 27.5 MHz frequency bands.

Featuring a 4.3-inch high-visibility color TFT LCD, the transceiver offers clear text and graphical menus with an adjustable night mode for bridge watchkeeping. It includes a dedicated built-in DSC watchkeeping receiver that continuously scans distress frequencies (such as 2187.5 kHz) while allowing simultaneous voice operations on other channels. Built to withstand punishing marine conditions, the control unit holds an IPX7 water immersion rating, while the heavy-duty RF unit is designed for secure mounting in ship radio rooms.

Key Features:
• GMDSS Class A DSC Compliance: Fully meets ITU-R M.493-13 and MED 2014/90/EU (Wheelmark) standards required for SOLAS commercial vessels.
• Dedicated Watchkeeping Receiver: Continuously monitors distress and safety digital selective calling (DSC) frequencies without interrupting audio channels.
• 4.3-Inch Color TFT Display: Wide-viewing-angle screen with intuitive software-driven menus and high-contrast dark mode for night operations.
• 125W PEP High RF Output: Delivers powerful long-range signal transmission across MF and HF marine bands when paired with an automatic antenna tuner (such as the AT-141).
• Heavy-Duty Marine Construction: Robust IPX7 front panel and rugged metallic chassis designed to resist continuous shipboard vibration, humidity, and salt spray.
