Muito Bom Fiquei plenamente satisfeito com a encomenda. Superou as minhas espectativas.

ICOM quality To listen well or call at sea. I will probably order the remote microphone kit to keep its functionality at the helm.

by Jean-Jacques M.

Top device for the price. Very good device, I use it on my commercial ship, I now have 2 that replaced the previous model. The language is very easy to understand and the volume is very high, so you can hear it even when the engine is making loud noises. The display is easy to read from any position. Installation is possible with a little skill and no problems.

by Torsten M.

Excellent quality-price ratio Operation, simple and reliable. Medium-high price but worth it.

Good device and competent review

Product details

Notes on programming:

This device has to be programmed with your personal data, such as: MMSI and/or ATIS numbers.

If you would like to use the ATIS function, this will have to be activated by us before shipping. Please let us know when placing your order.

You can programme the MMSI and then also the ATIS number yourself.

Alternatively, we can programme the device for you. For this we charge a programming fee.

If you would like us to programme the device, please let us know as you are making your order. Please add the above-mentioned programming accordingly and complete the form in full.

If additional channels (e.g. the Dutch channels) are to be activated, we charge our programming fee. The fee is only charged once per device.

The application for the allocation of the MMSI and ATIS number can be found in our Service/Downloads section.

The IC-M423GE from ICOM is equipped with an integrated GPS receiver, an easy to read display with white LCD background, a laser-cut keys and a handheld microphone. This model also includes the basic features such as active noise canceller, DSC function and the optional 2nd communication terminal via COMMANDMIC. Includes external GPS antenna.

Intuitive user interface, display and white illuminated buttons

ICOM's handy user interface is used in a lot of marine devices and offers very intuitive operation. A rotary knob and four navigational keys offer fast and easy access to the desired functions. The contrasting white background LC-display and precise keys match the design perfectly.

Active Noise-Canceller

The integrated noise-cancelling technology works while sending and receiving and can reduce background noise by up to 90%. This increases audibility - hear better and be heard better.

Built-in GPS receiver

The integrated GPS receiver shows the latest position as well as the time and can be used to make DSC calls.

Class D-DSC integrated

The integrated DSC surveillance function monitors the activity on channel 70 (DSC-channel), also during the reception on another channel. The DSC functions include: distress signal, individual and group calls, calls to other ships, request for position/calls for information, polling request and DSC test calls.

Optional COMMANDMIC™ HM195GB

With the optional COMMANDMIC™ HM-195GB you can operate the IC-M423GE remotely and use all its functions. Additionally, both devices are useable as an Intercom. Matching the IC-M423GE, the HM-195GB has the same white background lighting of the display and the keys.

10 W NF-performance, megaphone function and fog horn

The IC-M423GE has a 10-W-NF-amplifier that amplifies the NF-signals over additional external speakers. With the megafon function it is possible to make clear announcements to the deck personnel and other boats. The fog horn can also be used via external speakers.

Standard-NMEA-Interface

When an external GPS receiver is connected, the latest position and time are displayed on the IC-M423GE. Position data from other ships are being transmitted over the NMEA0183 connection of the IC-M423GE to external navigation devices.

Call AIS targets with MA-510TR

If an optional Class-B-AIS transponder MA-510TR is connected, individual DSC calls can be made to AIS targets, without having to enter the MMSI code before.

Further features

AquaQuake™-Draining-Function
Waterproof according to IPX7 (30 minutes in 1 m depth)
Two and three channel watch for simultaneously monitoring channel 16 and/or calling channel

Note

Function without distraction

I wanted a VHF with minimal functionality, and this is what I got. Simple operation, no frills (AIS, etc.), for emergency situations and easy communication. The built-in GPS is helpful. Super loud and clear.

Excellent radio station

This is the sixth unit I've installed on boats used intensively. It's very robust, with clear sound both when transmitting and receiving. Even after several years of use, the unit remains as functional as ever.
The infrasound drying, GPS, intercom, and megaphone functions are all appreciated.
It's highly durable, even when mounted externally on a RIB console.
