MF/HF MARINE TRANSCEIVER
IC-M803
Long Range Communications
Beyond the Horizon
Recreational SSB
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’s 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.
