VHF MARINE TRANSCEIVER
IC-M424G
Active Noise Cancelling Technology and Built-in GPS for Simple Installation
Easy to use, hear and find with Active Noise Cancelling and built-in GPS
The M424G is an enhanced version of the M424 fixed mount VHF/DSC and includes an integrated GPS Receiver, which allows current position and time to be used for DSC calls. With its striking white backlight LCD that improves visibility, the M424G also comes with the HM-205B speaker-microphone with a large speaker. The optional HM-195G COMMANDMIC™ also incorporates a white backlight LCD and laser-cut keypad.
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 CommandMicâ„¢ 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.
