Icom IC-M430 25W Fixed-Mount VHF Marine Radio with Class D DSC, Built-In GPS, Color Display & NMEA 2000 (M430 11 USA)

The Icom IC-M430 combines essential marine VHF communications with a slim helm-friendly design. This US-market black fixed-mount transceiver delivers selectable 25W or 1W RF output, a color TFT display, integrated GNSS positioning, built-in Class D Digital Selective Calling (DSC), and both NMEA 2000 and NMEA 0183-HS networking. Its shallow chassis and concealed-hardware mounting are designed for modern consoles and space-constrained installations.

Key Features

• 25W or 1W selectable VHF RF transmit power for routine marine communications and close-range operation.
• Integrated Class D DSC provides an independent distress control and DSC direct calling when properly configured with an MMSI.
• Built-in GNSS receiver and internal GPS antenna provide positioning for DSC; optional UX-241 external antenna supports installations with limited satellite reception.
• Bright color TFT LCD with Light, Dark and Night display modes and backlit operating keys.
• NMEA 2000 and NMEA 0183-HS connections support sharing compatible navigation and communication data.
• Slim 2.1-inch chassis depth and direct flush-mount method with concealed mounting hardware.
• HM-205RB speaker microphone can connect at the front or rear with appropriate optional extension hardware.
• Optional HM-195GB/GW CommandMic supports a second station and intercom operation using a compatible extension setup.
• Built-in hailer and foghorn functions, 25W typical hailer output, and active noise cancellation.
• NOAA weather channels with alert function, Dualwatch/Tri-watch, priority/normal scanning and four-digit channel support.
• IPX7 waterproof rating and AquaQuake water-draining function.
• Antenna VSWR detection provides an alert about antenna-system problems.

Compatibility

• For 12V nominal marine DC systems operating within the manufacturer-specified 11.7–15.9V input range.
• Works with a marine VHF antenna and 50-ohm antenna feedline; antenna and antenna cable are selected separately.
• Connects with compatible NMEA 2000 and NMEA 0183-HS equipment using properly installed network cabling.
• HM-205RB speaker microphone is included; optional HM-195GB/GW CommandMic, UX-241 external GNSS antenna and cable adapters can extend installation options.
• An AIS target can be selected for an individual DSC call when connected with compatible Icom MA-510TR data. The IC-M430 is not an AIS receiver or transponder.

Installation Notes

• Register/program the correct vessel MMSI to use DSC functionality.
• Install the radio using the supplied mounting bracket hardware or flush-mount gasket according to the installation instructions.
• Ensure access to the rear connections and adequate cable bend clearance; a VHF antenna is required for radio operation.
• Route and terminate NMEA network and DC/AF/DATA wiring according to the system installation guidelines.
• Configure the built-in GNSS receiver with a suitable view for satellite reception; install the optional external GNSS antenna if the helm location blocks reception.
