Icom IC-M330G Compact Fixed-Mount VHF Marine Radio with GPS (Black / White)

The IC-M330G is a compact fixed-mount marine radio with built-in GPS — 156.5×66.5×88.2mm, 730g — for vessels where both space and independent navigation are constraints. The palm-sized chassis installs in tight console positions where standard fixed-mounts cannot fit, while the built-in GPS/GLONASS/SBAS receiver operates independently of the chartplotter. The supplied puck antenna (5m cable) mounts on deck for a clear sky view; once installed, the radio has a continuous, independent position source for DSC distress calls that functions even if the MFD or chartplotter loses power.

RF output is 25W (Hi) / 1W (Lo) across USA, Canadian, and international VHF marine channels, including NOAA weather channels with weather alert. The dedicated CH70 receiver monitors Channel 70 for DSC calls continuously — even while the radio operates on a working channel. Class D DSC covers distress, individual, group, all ships, urgency, safety, position request/report, polling, and test calls. Receiver selectivity and intermodulation both exceed 70 dB on the main receiver.

AquaQuake™ vibrates the speaker grille to expel trapped water after wave wash or rain, preventing muffled audio after submersion. IPX7 protection covers 1 meter for 30 minutes. Audio output is 4.5W typical into 4Ω — sufficient for open helm stations without an external speaker.

NMEA 0183 input (RMC, GGA, GNS, GLL, VTG) also accepts position data from a chartplotter as an alternative or backup GPS source. NMEA output (DSC, DSE, RMC, GSA, GSV) sends DSC event data and position sentences to connected navigation equipment. The IC-M330G is compatible with the Icom MA-500TR Class B AIS transponder for integrated AIS display and DSC calling from AIS targets. FCC Part 80 certified for USA VHF marine operation.

The Icom IC-M330G is FCC Part 80 certified for USA VHF marine channels. For recreational vessels operating exclusively on domestic USA inland and coastal waters, no operator license is required. A Restricted Radiotelephone Operator Permit is required when operating on international waters or at foreign ports.

DSC distress calling requires an MMSI (Maritime Mobile Service Identity) number programmed into the radio before the distress function is active. For USA recreational vessels, MMSI registration is free through BoatUS (www.boatus.com/mmsi) or Sea Tow. Commercial vessels register MMSI through the FCC directly. The MMSI is a unique 9-digit number tied to your vessel.

The IC-M330G built-in GPS/GLONASS/SBAS receiver automatically embeds your vessel's position coordinates into every DSC distress call — including in scenarios where the chartplotter or MFD has lost power. The supplied puck antenna mounts on deck; once installed, the position source operates independently of all other electronics aboard. This makes the IC-M330G the recommended option for single-handed sailors, offshore passages, and any vessel where chartplotter reliability in an emergency cannot be assumed.
