Enquire About this Product Icom M423 VHF/DSC Marine Transceiver

The ICOM IC-M423 is Icom's next generation VHF/DSC. A compact radio that will fit easily into any console, size does not mean a loss of performance.  Boasting and packing a proverbial punch with its audio of 10W from its loud speaker makes sure you will clearly hear calls. The IC-M423 also has a Public Address & Fog Horn function so when attached to a hailer horn will expand the usefulness of this new radio.

Active Noise Cancelling Technology

The built-in bidirectional active noise canceller reduces background noise to up to 90% and improves both  your transmitted voice and incoming calls. This could be really essential for you, making you heard when you  really need to, such as when the weather conditions are poor or if engines are running.

New Marine Family Common User Interface

The Icom IC-M423 has an easy to use interface that will be incorporated into future Icom radios.  The common  Marine Family User Interface provides simple operation for the boat owner.  A rotary selector, directional  keypad provides intuitive operation. The high definition dot matrix display allows all information to be  clearly viewed. 

10W Loud Audio, Public Address and Foghorn

The Icom IC-M423 has a built-in 10W amplifier that increases the audio output from an additional external  speaker. The public address function allows you to make an announcement from the microphone like a loud  speaker, and the foghorn can also be emitted from the additional external speaker.

Built-in Class D DSC

The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, 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.

Common GPS/NAV Interface

When connected to an external GPS receiver, current position and time are shown on the IC-M423's  display. When receiving position information from another vessel, the IC-M423 can transfer it to a  navigational device via NMEA 0183 connectivity.

Compatible with Icom MA-500TR Class B AIS Transponder

The Icom IC-M423 can be integrated with the Icom’s MA-500TR Class B AIS Transponder allowing you to  transmit DSC individual calls to a selected vessel instantly without manual MMSI entry; very handy if you are  waiting to contact vessels on the AIS screen, an essential safety feature in an emergency.

IPX7 Submersible Protection (1.0m depth for 30 minutes)

The Icom IC-M423 withstands submersion in up to 1.0m depth of water for 30 minutes. It is equivalent to the IPX7  standard.
