Pachet BLU marin IC-M804

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

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

The IC-M804 is equipped with a 4.3-inch TFT color LCD screen. This screen 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 Side Band (SSB) voice communication for long-range use.Digital Selective Calling (DSC Class E) for distress and safety calls.An integrated GNSS receiver for location 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 the Digital Selective Calling (DSC) system. 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 the range of VHF radios, making it ideal for offshore sailing.

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 for quick and easy channel, menu, and setting selection.

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 transmission and reception performance of the IC-M804 across the different 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 an adequate cross-section to prevent voltage drops.Ensure a solid ground connection to the vessel for safety and performance.Protect all cables from interference and physical damage.Follow the installation manual instructions strictly 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 information (such as GNSS position data) with other navigation and communication equipment onboard the vessel.

Yes, the IC-M804 has an audio output that allows connection of 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 to receive 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 you to quickly send 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.
