IC-M804 MF/HF Marine SSB Transceiver

SKU: ICO-0035

The IC-M804 is a long-range MF/HF Class E DSC radio for ocean-going sailors and commercial non GMDSS operators. Based on the MED approved Class A GMDSS radio GM800, the IC-M804 is packed with features to keep users safe including an intuitive user interface, and colour TFT LCD display, audio replay, GPS and more.

The IC-M804 Conforms to the latest European and International standards and is CE marked for the European Radio Equipment Directive (RED). It is currently the only CE-marked Class E DSC Marine MF/HF radio available in the market. (At time of publication (10/11/21).

Class E DSC MF/HF SSB Radio

The IC-M804 meets ITU-R M.493-15 Class E DSC regulations and is based on the MED approved GM800 Class A GMDSS radio. The IC-M804 will provide long-distance communications for non-GMDSS vessels with almost identical features and functions except for the different DSC class. In an emergency, by pressing the large independent Distress button you will be able to send an automated digital Distress signal. The digital Distress signal with GNSS coordinates calls for help from other ships or coastal stations.

Built-in DSC Watch-Keeping Receiver

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.

Intuitive User Interface

The combination of the directional keypad and soft keys provides a simple operation. The most common functions are assigned to soft keys (at the bottom of the display) for quick push function access. The large ten-key pad enables you to smoothly enter channel numbers, MMSI numbers with ID names and so on.

4.3 inch Wide Viewing Angle Colour TFT Display

A high-resolution colour LCD provides an almost 180 degree very wide viewing angle and displays characters and function icons clearly. The night mode display ensures good readability in the dark for further convenience.

NMEA 2000™, NMEA 0183/-HS Connectivity

Using NMEA 2000™ connectivity, the IC-M804 can exchange GNSS, DSC call information, radio information and PGN list data on the network. NMEA 0183/-HS GNSS position data can also be converted to NMEA 2000™ data for other equipment.

Two Minutes Voice Recorder Memory  

The Voice Recorder function automatically records the last 2 minutes of receiving audio.

Ready for HF E-mail Operation

The IC-M804 can be set to memorise your HF e-mail access frequency, mode and filter settings into the e-mail channels and be selected with a simple operation. Up to 160 e-mail frequency channels and connection terminals for a PC and e-mail modem are available.

*Please consult with an HF e-mail provider for details.

Meets Strict Environmental Requirements

The IC-M804 has passed rigorous environmental testing and quality assurance processes. It is designed to provide reliable operation and corrosion-resistant durability under harsh maritime environments. The controller has IPX7 protection (1 m depth of water for 30 minutes).

AT-141 Automatic Antenna Tuner

The AT-141 automatic antenna tuner matches all bands to your antenna. If due to a fault the automatic tuner cannot tune the antenna, the IC-M804 bypasses the tuner and will display an alert on the display.
