IC-M424 VHF Marine Transceiver

Active noise cancelling

The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. You will hear better, be heard better.

10W Loud Audio, Public Address and Foghorn

The IC-M424 has a built-in 10W amplifier that increases the audio output from 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.

New Optional COMMANDMICIVTM HM-195B/SW

The new optional COMMANDMICIV makes it convenient for using the IC-M424 from a separate cabin or tower. All functions of the IC-M424 can be controlled from the COMMANDMICIV.

Common GPS/NAV Interface

When connected to an external GPS receiver, current position and time are shown on the IC-M424's display. When receiving position information from another vessel, the IC-M424 can transfer it to a navigational device via NMEA 0183 connectivity.

MarineCommanderTM Compatible

When connected to the MarineCommander, the received DSC message pops up on the multi-function display.
