BLU marine IC-M804

An SSB (Single Sideband) marine radio, also called MF/HF SSB, is a long-range transceiver used for offshore communication beyond VHF radio range. The Icom IC-M804 enables vessels to establish voice and data communications over very long distances, receive weather and safety information, and send distress calls thanks to its class E Digital Selective Calling (DSC) function.

The Icom IC-M804 is certified to several international standards for marine equipment. It complies with ITU-R M.493-15 regulations for the ASN system and ETSI EN 300 338-4 Class E DSC for Class E Digital Selective Calling (DSC), ensuring its reliability and compliance for distress and general communications at sea.

The Icom IC-M804 has an IPX7 waterproof rating. This certification means the unit is protected against temporary immersion in water. Specifically, it can be submerged up to 1 meter deep for a maximum of 30 minutes without sustaining damage.

Yes, the Icom IC-M804 integrates a GNSS (Global Navigation Satellite System) receiver that includes GPS compatibility. This built-in receiver allows the device to determine its position accurately, which is essential for ASN (Digital Selective Calling) functions and for displaying coordinates on the screen.

The Icom IC-M804 provides high transmit power for long-range communications. Its maximum output power is 125 W PEP (Peak Envelope Power), enabling it to reach other stations effectively on MF/HF bands.

The DSC (Digital Selective Calling) Class E system integrated into the IC-M804 is a safety feature that allows sending and receiving selective digital calls. It facilitates distress communication by automatically transmitting the vessel's position and the nature of the emergency to coastal stations and other DSC-equipped vessels. It also enables individual or group calls.

The Icom IC-M804 operates on MF/HF (Medium Frequency/High Frequency) bands. It can transmit from 1.6 MHz to 27.5 MHz and receive over a wider range from 0.5 MHz to 29.999 MHz, covering international marine frequencies and broadcast frequencies.

Yes, thanks to its built-in Class E ASN (Digital Selective Calling) system and compliance with ITU-R M.493-15 standards, the IC-M804 is fully compatible with international distress calls. In an emergency, it can send a digital distress message containing the vessel’s identification, position, and the nature of the emergency to coastal stations and nearby vessels.

The Icom IC-M804 is equipped with a 4.3-inch TFT color LCD display. This screen provides excellent visibility, even in bright sunlight, and clearly displays navigation data, frequencies, menus, and DSC messages.

Yes, the Icom IC-M804 is designed for voice communications in SSB (Single Sideband) mode on MF/HF bands. Additionally, it can be interfaced with external modems, such as PACTOR modems, to enable data communications, including sending and receiving emails or files via radio networks.

For the Icom IC-M804, a marine HF SSB antenna is required. This is typically a whip antenna or a long wire, designed to operate over a wide frequency range. The use of an automatic antenna tuner is highly recommended to match the antenna across the different frequencies used and optimize transmission and reception performance.

Yes, an automatic antenna coupler is highly recommended and often considered essential for using the IC-M804. Models such as the Icom AT-141 are designed to integrate seamlessly. The antenna coupler automatically matches the antenna impedance to that of the transceiver, ensuring maximum transmission efficiency and protecting the device from damage caused by impedance mismatch.

The Icom IC-M804 is designed to be powered by the boat's electrical system. There are versions for 12 V DC power supply and others for 24 V DC. It is crucial to check the specific version of your unit to ensure correct power supply and avoid any damage. Professional installation is recommended for the electrical wiring.

Yes, the Icom IC-M804 has a dedicated audio output for connecting an external speaker. This can be particularly useful in noisy environments or if you wish to route the sound to another area of the boat for improved listening of communications.

Yes, the Icom IC-M804 can be connected to a PC. This connection is primarily used for programming, software updates via Icom's specific tools, or interfacing with external data modems (such as PACTOR modems) that require a serial connection for data transfer.

The standard warranty for the Icom IC-M804 typically covers manufacturing and material defects under normal operating conditions. It ensures the device will function according to its specifications. For specific coverage details, consult the manufacturer's or retailer's documentation provided at the time of purchase.

The international validity of the warranty for the Icom IC-M804 depends on the manufacturer's specific policies and the region of purchase. Icom is a global brand, and its products often benefit from international support. It is advisable to check the warranty terms and conditions with the authorized Icom distributor in your region or the point of sale to obtain precise information on international coverage.
