Class E DSC MF/HF Radio wtih Wide Viewing Angle Color TFT LCD
Reliable Distant Communication Beyond the Horizon
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.

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. Even when the radio is installed on the instrumental panel, the operator can clearly see the display information from various viewing angles. The night mode display ensures good readability in low light conditions. Integrated speaker eliminates need to install a separate speaker.
Distress Button for Emergency
If in an emergency situation, the large independent Distress button enables you to immediately send
an automated digital Distress signal, with GPS coordinates, to call for help from other ships or coast stations.
Built-in DSC Watch-Keeping Receiver (Class-E DSC)
The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. A total of 100 MMSI num- bers (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.
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
Received RF signals are directly converted to digital signals and processed in the Field-Programmable Gate Array (FPGA), mak- ing it possible to simplify circuit construction. It also improves receiver sensitivity, and audio clarity over conventional radio systems.
Integrated GPS Receiver
The GPS receiver 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 output port for use with other devices.
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. The ten-key pad enables you to smoothly enter channel numbers, MMSI numbers with ID names and so on. In addition, one of software key functions can be as- signed to the microphone’s programmable button for quick access.
Ready 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.
