ICOM IC-M804 jūrinis BLU paketas

The IC-M804 marine MF/HF radio pack is a medium/high-frequency (MF/HF) transceiver designed for long-range maritime communications. It enables voice communications (SSB) and digital distress calls (DSC Class E), essential for safety and navigation offshore.

The IC-M804 transceiver provides a high output power of 125 W (PEP), ensuring extended communication range for maritime applications.

The IC-M804 is equipped with a 4.3-inch TFT color LCD screen. This display provides excellent visibility and an intuitive user interface to facilitate access to functions and information.

The main communication features of the IC-M804 include:

Single sideband (SSB) voice communication for long-range use.The Digital Selective Calling (DSC Class E) system for distress and safety calls.An integrated GNSS receiver for position fixing and DSC functions.

Yes, the IC-M804 is equipped with an integrated GNSS (Global Navigation Satellite System) receiver. This allows it to determine its position accurately, which is essential for Digital Selective Calling (DSC) functions and for sending distress messages.

The IC-M804 is certified to international standards for marine communication equipment, including:

ITU-R M.493-15 for Digital Selective Calling (DSC). ETSI EN 300 338-4 Class E DSC, confirming compliance with European requirements for MF/HF DSC radios.

Yes, absolutely. As an MF/HF (medium/high frequency) transceiver, the IC-M804 is specifically designed for very long-range maritime communications far beyond VHF radio range, making it ideal for offshore navigation.

The IC-M804 user interface is designed to be intuitive and easy to use, even at sea. It features a 4.3-inch TFT color LCD screen and a multifunction dial that allows quick and easy selection of channels, menus, and settings.

The IC-M804 covers the following frequency bands:

Transmission (Tx): 1.6 MHz to 27.5 MHz (ITU maritime channels). Reception (Rx): 0.5 MHz to 29.999 MHz (general coverage).

Yes, to optimize the transmission and reception performance of the IC-M804 across the MF/HF frequency bands, it is strongly recommended to use an automatic antenna tuner. This device adjusts the antenna impedance to match that of the transceiver for maximum efficiency.

When wiring the IC-M804, several key points must be observed:

Use power cables with adequate cross-section to prevent voltage drops.Ensure a proper connection to the vessel’s ground for safety and performance.Protect all cables from interference and physical damage.Follow the installation manual instructions meticulously for all connections (power, antenna, accessories).

Yes, the IC-M804 is compatible with maritime data communication systems. It supports NMEA 0183 and NMEA 2000 interfaces, allowing it to exchange data (such as GNSS position data) with other navigation and communication equipment onboard.

Yes, the IC-M804 has an audio output that allows you to connect an external speaker. This can be useful for improving audio clarity in a noisy environment or for routing sound to another area of the vessel.

Yes, thanks to its wide reception coverage (0.5 MHz to 29.999 MHz) and its MF/HF capabilities, the IC-M804 is perfectly suited for receiving marine weather bulletins broadcast on the appropriate frequencies. It can also receive Maritime Safety Information (MSI) via the DSC system.

The IC-M804 is equipped with a Class E DSC (Digital Selective Calling) system. In an emergency, it allows for the rapid transmission of a digital distress call with position information (via the integrated GNSS) to other vessels and coastal stations. It can also receive and display distress calls from other units.
