Why Buy From Us

IC-M510BB GW 21 Black Box VHF with White Command Mic & 3 Command Mic Ports

Icom’s IC-M510BB is perfect for boats that need AIS to receive functionality without taking up precious helm space. The supplied white CommandMic™ provides all the safety and communication functions for commercial and leisure boaters.

Clean Installation for Limited Helm Space

The IC-M510BB consists of a CommandMic™ and a black box RF unit. Use the CommandMic™ for all operations, including DSC. Install the RF unit out of sight, placing it up to 60 ft (18.3 m)* away from the CommandMic™.

*Two OPC-1541 cables are required for the 60 ft installation

CommandMic™ Stations

Add up to two additional CommandMic™ microphones for boats requiring two or three comms stations. Extend communication points around the boat, including the cockpit, flybridge, and tower. Access the intercom functions for one-to-all or one-to-one communications on the boat.

AIS Receive

The IC-M510BB includes an integrated AIS receiver, perfect for remote station information via the CommandMic™, or integrated into the NMEA 2000® bus to display radar and chart plotter information on an MFD (Multi-Function Display).

DSC Functionality and Remote Control

In addition to the conveniently located DSC button on the back of every CommandMic™, the IC-M510BB introduces a dedicated DSC Remote Control (EN 300 338-8 compatible) terminal, allowing a connection to an external device to centralize emergency communications control.

NMEA200® and NMEA 0183-HS®

The NMEA 2000® network provides plug-and-play data communication to interconnect other marine equipment, such as an MFD (Multi-Function Display). The radio can send AIS, GNSS (GPS) position, DSC call, and radio channels to other equipment.

Class D DSC Functionality

On the back of every CommandMic™ is a conveniently located DSC button. Once triggered, the IC-M510BB transmits a DSC alert signal to nearby vessels with the MMSI* and GPS location of your vessel. *MMSI number must be obtained and programmed for each vessel/radio.

Loud One-Way RX Hailer

The built-in 15W amplifier increases the audio output of an external hailer speaker. The one-way RX hailer function enables you to broadcast radio traffic through the hailer speaker to listen to radio traffic on the deck or tower. You can also hear foghorn patterns from the hailer speaker.

Active Noise Cancelling

The Active Noise cancellation function digitally removes background noise from transmitting and receiving audio to provide clear communications in noisy maritime environments.
