Icom M424G VHF Radio

The IC-M424G is a full-featured, compact, rugged VHF radio built for the harsh marine environment. Not only is the unit waterproof, it is submersible for up to 30 minutes at a depth of 1 meter.

Integrated GPS Receiver

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. In addition, the optional HM-195G COMMANDMIC™ also incorporates a white backlight LCD and laser-cut keypad.

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. Hear and be heard more clearly.

Intuitive User Interface

Incorporates Icom’s common Marine Family User Interface design 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.
