IC-M803 MF/HF Marine Transceiver

Class E DSC MF/HF SSB Radio with Color TFT Display

Long Range Communications Beyond the Horizon

IC-M803

The IC-M803 is designed to be a companion to our VHF transceiver IC-M605. The front panel layout, color TFT display and user interface are similar to each other. Take advantages of the shared functionality to complete your communications needs.

  • 150 W (PEP) of powerful RF output
  • Optional AT-140 automatic antenna tuner
  • IPX7 waterproof remote controller
  • 0.5–29.999 MHz continuous receiver coverage
  • NMEA 0183 Version 4.10 data input/output (4800–38400 bps)

Built-in DSC Watch-Keeping Receiver with the Multiple Task Mode

The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. A total of 100 MMSI numbers (75 Individual and 25 Group) for DSC calls can be stored with a 10-character ID name. When you receive a DSC call, while you are in process with another DSC call, the IC-M803 can hold both DSC procedures to switch between the DSC calls with the Multiple Task Mode function.

Intuitive User Interface

A combination of the large main dial and software keys at the bottom of the display, provides simple operation and easy access to often used functions. You can smoothly enter channel numbers, MMSI numbers, vessel names with the alpha-numeric keypad. In addition, one of software key functions can be assigned to the microphone’s programmable button for quick access.

4.3 inch Wide Viewing Angle Color TFT Display

The 4.3 inch color TFT display provides an almost 180 degree very wide viewing angle and displays high resolution characters and function icons. You can clearly see the display information from various viewing angles. So the radio can be installed without choosing the installation place. The night mode display ensures good readability in low light conditions.

Integrated GPS Receiver

The GPS receiver which includes GPS, GLONASS and SBAS function, is integrated into the IC-M803. Your position data, course, speed and UTC data can be received with a simple connection to the supplied GPS antenna. The position data can be output from the NMEA 0183 port for use with other devices.

Two Minutes Instant Replay Memory

The Instant Replay function automatically saves the received audio. You can replay the received audio, and not miss any incoming calls.

Advanced RF Direct Sampling System

The latest digital signal processing system is employed to the IC-M803. The system totally improves receiver sensitivity, and audio clarity over conventional radio systems.

IC-M803Ready for HF E-mail Operation

The IC-M803 can be set to memorize your HF e-mail access frequency, mode and bandwidth setting into the e-mail channels. Up to 160 e-mail frequency channels, and connection terminals for a PC and e-mail modem are available.
