ICOM IC-M803 MF/HF Marine Transceiver
The Icom IC-M803 is a remarkable MF/HF marine transceiver designed for ocean-going sailors, particularly blue-water cruisers who require Single-Side Band (SSB) communication on board. Let’s explore its features:
- Long-Range Communication:
- The IC-M803 ensures reliable communication beyond the horizon.
- It operates in the MF/HF frequency range and supports Class E DSC (Digital Selective Calling).
- Integrated GPS Receiver:
- The IC-M803 includes a GPS receiver that combines GPS, GLONASS, and SBAS functions.
- It provides position data, course, speed, and UTC information.
- You can output position data via the NMEA 0183 port for use with other devices.
- Instant Replay Memory:
- The Instant Replay function automatically saves received audio.
- You won’t miss any incoming calls, as you can replay the audio.
- Advanced RF Direct Sampling System:
- The IC-M803 employs the latest digital signal processing system, enhancing receiver sensitivity and audio clarity compared to conventional radio systems.
- HF E-mail Operation:
- Set up to 160 e-mail frequency channels and connect terminals for a PC and e-mail modem.
- Ideal for HF e-mail communication.
- Companion to IC-M605:
- The IC-M803 complements the Icom VHF transceiver IC-M605.
- Similar front panel layout, color TFT display, and user interface make them a powerful combination for complete communication needs.
Whether you’re navigating the open seas or exploring remote waters, the IC-M803 ensures reliable and efficient communication for sailors. 🌊📻
