VHF hajó rádió fekete doboz 156–163 MHz 25W, DSC D osztály

A VHF black box is a modular system where the radio's main unit is installed out of sight, for example in a console or a locker. Full control of the VHF is handled via a remote microphone (CommandMic), saving valuable dashboard space.

No, the IC-M400BBE VHF is now a discontinued product from the manufacturer. It is advantageously replaced by the new-generation models IC-M410BB and IC-M510BB. However, it remains an excellent opportunity at a reduced price for standard replacement of an existing installation.

The central unit is very compact. It measures approximately 216 mm in width, 79 mm in height, and 125 mm in depth, which makes it much easier to integrate into the tight spaces on your boat.

Yes, the main unit of this VHF complies with IPX7 waterproofing standards. This means it is designed to withstand temporary immersion in water (up to 1 meter depth for 30 minutes).

This fixed VHF radio offers switchable transmit power. You can transmit at 25 Watts for long-distance communications, or reduce power to 1 Watt for local communications, which saves onboard energy.

The Digital Selective Calling (DSC) Class D is a critical safety function at sea. The radio includes an independent receiver dedicated exclusively to channel 70. This ensures continuous and automatic monitoring of distress calls, even when you are using another channel for regular voice communications.

Yes, it has a built-in audio amplifier delivering over 10 W of power. By connecting a compatible external speaker (PA - Public Address function), you can use it as a foghorn or a deck sound system.

The central unit is installed invisibly in a console, a locker, or behind a partition using its mounting bracket. Only the remote microphone and its connection port must be installed in an accessible location on the dashboard or at the chart table.

VHF radios require a nominal 13.8 V DC power supply (acceptable range: 12.0 to 13.8 V DC) with negative ground. Maximum current draw during full-power transmission (25 W) is 5.5 A.

Yes, it is entirely possible to connect an external speaker. The device provides an audio output power of more than 10 W (under 4 Ω) via the blue (+) and black (-) wires, ensuring excellent audibility even in a noisy environment.

Connection to the NMEA 0183 network is made via the dedicated wires in the loom: the yellow wire corresponds to the GPS input (Data-H) and the green wire to the GPS input (Data-L). This allows the VHF to receive position data required for proper AIS operation.

You need a standard marine VHF antenna with a nominal impedance of 50 Ω. The antenna is not supplied with the device and must be installed as high as possible and clear of any obstacles to optimize your communication range.

This black box is designed to be controlled exclusively by a remote microphone from the HM-195 series (such as the HM-195B or HM-195SW models). Note that, depending on the package, this microphone may be sold separately.

Yes, when correctly connected to a chartplotter or compatible navigation equipment via NMEA 0183, it can receive and transmit to the display the position data of other vessels obtained during ASN calls.

This model being at the end of its commercial life, ICOM now offers the next-generation black box VHFs IC-M410BB and IC-M510BB. These new models include modern features such as NMEA 2000 compatibility and the ability to connect multiple handsets simultaneously.

Yes, to use a fixed marine VHF radio with DSC (Digital Selective Calling) function at sea, you must hold at minimum the SRC (Short Range Certificate) or a valid recreational craft driving licence, depending on your navigation area and current regulations.
