ICOM IC-M804 — jūras MF/HF radiostacijas komplekts

The IC-M804 marine MF/HF pack is a medium/high-frequency (MF/HF) transceiver designed for long-distance maritime communications. It enables 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 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 IC-M804’s main communication features include:

Single Side Band (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 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 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 the range of VHF radios, making it ideal for offshore navigation.

The user interface of the IC-M804 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 respected:

Use power cables with adequate cross-section to avoid voltage drops.Ensure a proper ground connection to the vessel for safety and performance.Protect all cables from interference and physical damage.Follow the installation manual instructions precisely 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, enabling it to exchange data (such as GNSS position data) with other navigation and communication equipment aboard the vessel.

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 the 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 rapid transmission of a digital distress call with position data (via integrated GNSS) to other vessels and coastal stations. It can also receive and display distress calls from other units.
