IC-M803 Transceptor Marítimo SSB ICOM

The M803 is the long range digital communication radio for any cruiser. Reach both marine and ham frequencies with the Class E DSC MF/HF certification. It is packed with features to keep users safe such as a distress call button, audio replay, GPS and more. The intuitive interface of the color TFT display and the similarity of the user interface of the M605 allows for easy operation between the two radios. The M803 also includes an advanced RF direct simple sampling system that improves higher receiver sensitivity and higher quality audio.


Output Power:



  0.5-29.99 MHz


  830 (160 programmable, 72 ITU SSN duplex, 249 ITU SSB simplex, 193 ITU FSK duplex, 160 email)


  IPX7 (controller only)



Large Color Display

Users will like the large 4.3" wide viewing angle color TFT display. Clearly see the high resolution display icons on the LCD screen from numerous positions with the nearly 180 degree wide viewing angle, which provides various installation placement possibilities. The night mode display offers readability in low-light conditions.

Intuitive User Interface

Smoothly operate and sail with the M803’s large main dial and keys to access functions such as accessing MMSI numbers, vessel numbers, and channels with the full alpha-numeric keypad. Assign one of the software key functions to the microphone’s programmable button for quick access. Additionally the head unit offers programmable keys for customizable access.

Emergency Distress Button

The M803’s big and easily identifiable emergency distress button is encased in a spring loaded cover. Once pressed a digital distress signal is sent with GPS coordinates and calls for help to other ships or coast stations. The GPS receiver offers GPS, GLONASS, SBAS, position data, speed and UTC data when using the supplied GPS antenna. Position data may be output from the NMEA 0183 port for use with other devices.

Dedicated DSC Scanning

The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. If you are in process with a DSC call and receive another call, the M803 can switch between calls with the Multiple Task Mode function. 100 MMSI numbers (75 individual/25 group) for DSC calls can be stored with a 10-character name.

Two Minute Memory Instant Replay Memory

The Instant Replay Function allows users to replay up to two minutes of previous conversations or calls. The function constantly loops and records over older audio.

Additional Features

  • NMEA 0183 Version 4.10 data input/output (4800-38400 bps)
  • HF email operation with frequency, mode and bandwidth memorization*
  • *Consult with an HF email provider for details
