VHF MARINE TRANSCEIVER

IC-M424G

Active Noise Cancelling Technology and Built-in GPS for Simple Installation

Open

Intuitive User Interface and White Backlit LCD and Keypad

Incorporating Icom's common Marine Family User Interface designed for simple, intuitive operation. A rotary selector and directional keypad provide quick and easy access to the intended functions. The high contrast white backlit LCD and laser-cut keypad match well with modern boat designs.

Active Noise Cancelling

The built-in active noise cancelling provides superb performance. It reduces background noise up to 90% in the received signal and 30% in the transmits signal.

10 W Loud Audio, Public Address and Foghorn

The IC-M424G has a built-in 10 W amplifier that increases the audio output to an external PA speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, the foghorn can also be emitted from the external PA 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.

Built-in GPS Receiver

The built-in GPS receiver shows your current position, date/time and can be used for DSC calls. The GPS data source is selectable from internal and external GPS.

Optional White Backlit COMMANDMIC™ HM-195GB/GW

The optional white backlit COMMANDMIC makes it convenient for using the IC-M424G from a separate cabin or tower. All functions of the IC-M424G can be controlled from the COMMANDMIC and can be used as an intercom with the IC-M424G.

AIS Target Call with MA-510TR/MA-500TR

When connected to the optional MA-510TR/MA-500TR Class B AIS transponder, the AIS target call function allows you to make an individual DSC call without having to manually input an MMSI number.
