Icom IC-M802 Transceiver Specification

The Icom IC-M802 is a high-performance, long-range MF/HF marine transceiver designed for professional maritime communication. It operates across all HF marine bands with coverage from 1.6 to 27.5 MHz, offering reliable communication over vast distances. The transceiver boasts a powerful 150W (PEP) output, ensuring clear signal transmission even in challenging conditions. Equipped with an intuitive and user-friendly interface, the IC-M802 features a large LCD display and simple menu-driven controls for seamless operation. The inclusion of a dedicated emergency button provides quick access to distress frequencies, enhancing safety at sea.

The transceiver supports Digital Selective Calling (DSC) for automated distress signaling and direct dial calling, conforming to ITU Class E standards. The advanced digital signal processor (DSP) enhances audio clarity and performance by minimizing interference and background noise. The IC-M802 includes a built-in AT-140 automatic antenna tuner, ensuring optimal transmission efficiency by matching the antenna impedance across various frequencies.

Connectivity options are robust, with the inclusion of NMEA 0183 interface compatibility, allowing for integration with GPS and other navigational systems. The IC-M802 is housed in a durable, weather-resistant casing, meeting the rigorous demands of marine environments. It operates on a 13.8V DC power supply, typical for marine applications. Additional features include a comprehensive scanning function, dual watch capability, and memory channels for storing frequently-used frequencies. The Icom IC-M802 is recognized for its reliability, ease of use, and advanced functionality, making it an ideal choice for professional mariners requiring dependable communication solutions on the open seas.

Icom IC-M802 Transceiver F.A.Q.

How do I perform a factory reset on the Icom IC-M802?

To perform a factory reset on the Icom IC-M802, turn off the transceiver. Press and hold the [ENT] and [CLR] buttons while turning the power back on. This will reset the unit to its default factory settings.

What are the steps to update the firmware on the Icom IC-M802?

Updating the firmware on the IC-M802 requires downloading the latest firmware from Icom's official website. Connect the transceiver to your computer using the appropriate data cable, and follow the instructions provided with the firmware update package.

How can I improve the transmission quality of my Icom IC-M802?

Ensure that your antenna is properly installed and tuned. Check all connections for corrosion or damage. Additionally, adjust the RF gain and microphone gain settings on the transceiver for optimal performance.

What should I do if my Icom IC-M802 is not powering on?

First, check the power cable connections and ensure that the power source is providing the proper voltage. Inspect the fuse in the power cable for any signs of damage. If the issue persists, consult an authorized Icom service center.

How do I troubleshoot poor reception on the IC-M802?

Start by checking the antenna and coaxial cable for any faults or damage. Ensure that the RF gain is set appropriately. Interference from other electronic devices can also impact reception, so try relocating the transceiver or minimizing nearby electronic interference.

How can I set up digital communications using the Icom IC-M802?

To set up digital communications, connect the transceiver to a computer using a compatible interface such as a PACTOR modem. Configure the transceiver and software settings according to the digital mode you wish to use, such as Winlink or SailMail.

What maintenance is required for the Icom IC-M802?

Regularly inspect and clean the transceiver and its connections to prevent dust and corrosion. Check the antenna system periodically for any signs of wear. Ensure that firmware and software updates are applied as needed.

How do I adjust the squelch setting on the Icom IC-M802?

Press the [SQL] button on the front panel and then rotate the main dial to adjust the squelch level. Set it just above the noise level to ensure clear reception without unwanted background noise.

How can I extend the lifespan of my Icom IC-M802?

To extend the lifespan of your IC-M802, keep it dry and clean, avoid exposure to extreme temperatures, and perform regular maintenance checks on the antenna and power connections. Store the unit in a safe, protected location when not in use.

What are common error codes on the IC-M802 and how can I resolve them?

Common error codes include "ERR" for general errors and "BUSY" when the channel is occupied. For "ERR" codes, restart the transceiver and check all connections. For "BUSY," wait for the channel to clear or switch to another frequency.
