 Icom M803 Digital Marine Single Side Band Radio
 
 
	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: |  | 150W |  
	| Frequencies: |  | 0.5-29.99 MHz |  
	| Channels: |  | 830 (160 programmable, 72 ITU SSN duplex, 249 ITU SSB simplex, 193 ITU 
    FSK duplex, 160 email) |  
	| Waterproof: |  | IPX7 (controller only) |  
	| GPS: |  | Built-in |  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 M803s 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 
microphones programmable button for quick access. Additionally the head unit 
offers programmable keys for customizable access.
 Emergency Distress Button
	The M803s 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*
