The Icom IC-M803 is a long-range Class E DSC MF/HF Single Sideband (SSB) radiotelephone system manufactured by Icom Inc. in Japan. Engineered for long-distance communications on ocean cruisers, commercial fishing vessels, and workboats, the IC-M803 delivers up to 150 Watts of PEP RF output power across all maritime HF bands.

The system incorporates a high-resolution 4.3-inch color TFT display with a nearly 180-degree viewing angle and day/night screen modes. Built with an integrated multi-constellation GNSS receiver (GPS, GLONASS, SBAS), the radio automatically tracks position coordinates for immediate inclusion in digital selective calling (DSC) distress signals. Featuring an advanced RF direct sampling system for superior audio clarity, dedicated HF email channels, and an automatic two-minute instant audio replay function, the IC-M803 serves as a digital communications terminal for non-SOLAS long-range vessels.

Key Features:
• Class E DSC Certification: Includes a dedicated DSC watchkeeping receiver to monitor distress and safety frequencies continuously.
• Selectable 150W Output Power: Delivers 150W PEP RF output with selectable power levels (150W, 100W, 60W, 20W) for worldwide long-range propagation.
• High-Visibility Color TFT LCD: 4.3-inch color display with day/night modes and an intuitive interface designed as a companion to the IC-M605 VHF series.
• Integrated GNSS Receiver: Supplied with an external GPS antenna to acquire real-time position, speed, and time data for automated DSC calls.
• HF Email & Data Ready: Features 160 dedicated e-mail memory channels and terminal interfaces for direct connection to PC data modems.
• Two-Minute Instant Replay: Automatically records up to two minutes of incoming audio, allowing watchkeepers to re-hear missed voice broadcasts.
