ICOM IC-M330G VHF Marine Transceivers
The Icom IC-M330G is a high-performance VHF marine transceiver designed for use on boats and ships. Here are some key features of the IC-M330G:
- Ultra Compact Body: The IC-M330G has a palm-sized compact body, measuring 156.5 mm (width) × 66.5 mm (height) × 88.2 mm (depth). This compact size allows for flexible installation even in limited spaces.
- Clear Audio: A new speaker design delivers dynamic and clear sound over a wide bass and treble range. Even at full volume, the IC-M330G provides distortion-free clear audio.
- Built-in Class D DSC: The radio continuously monitors Channel 70 (CH70) for distress calls, even while you are receiving another channel. DSC functions include distress, individual, group, all ships, urgency, safety, position request/report, polling request, and DSC test calls.
- Class Leading Receiver Performance: The IC-M330G ensures reliable communication in RF busy environments like marinas, with excellent selectivity and IMD performance.
- Intuitive Operation: The combination of the directional keypad and soft keys provides simple, smooth operation. Most used functions are assigned to soft keys for quick one-push access.
- GPS Receiver Built-in (IC-M330G): The IC-M330G variant comes with a built-in GPS receiver that provides your location, bearing, and speed using information from GPS, GLONASS, and SBAS. The acquired position information can be used for DSC calls.
- IPX7 Submersible: The radio is submersible up to 1 meter depth of water for 30 minutes. Additionally, AquaQuake™ prevents audio degradation from a water-logged speaker.
- Other Features:
- Common NMEA interface for external GPS/NAV connection
- MA-500TR Class B AIS transponder compatible
- Tag scan and favorite channel functions
- Dual/tri-watch function for monitoring CH16 and/or call channel
- Priority scan function
- External speaker connection
- Weather channel with weather alert
- Supplied hand microphone (HM-235B/W) with channel up/down keys and a CH16/Call channel key
Whether you’re navigating the high seas or exploring coastal waters, the Icom IC-M330G is a reliable companion for marine communication. 🌊⚓
