Icom M801 Class A DSC GMDSS MF/HF Communication System
Class A DSC safety functionality combined with Icom's technology and value
Meets GMDSS requirements
The Icom M801 Class A GMDSS is designed for Class A DSC operation. Together with the standard AT-141 antenna tuner, it provides a complete GMDSS MF/HF communication system as required for Commercial Solas regulated vessels voyaging in the A2 sea area. The radio also meets MED 96/98/EC, "wheel mark" requirements for European merchant ships.
Built-in ITU Class A DSC
An independent DSC receiver on the Icom M801 Class A GMDSS constantly watches MF/HF DSC channels, while using another channel. The DSC allows you to call intended ship(s) or coast station(s) directly as well as all ships in the geographic area. A total of 100 MMSI IDs can be stored with a 10-character name. In addition, the self test function allows you to check the DSC functions.
Built-in DC-DC converter
The Icom M801 Class A GMDSS has a built-in DC-DC power converter, which provides stable 13.6V DC converted from a 24V DC power supply. A floating ground system is employed.
Optional automatic antenna tuner, AT-141
AT-141GMDSS Automatic Antenna Tuner
The A141, automatic antenna tuner, tunes all frequencies in all modes. It easily connects to the Icom M801 Class A GMDSS with the optional shielded cable. If the tuner cannot tune the antenna, the Icom M801 Class A GMDSS bypasses the tuner and displays an alert on the display.
Large LCD with full dot-matrix characters
The Icom M801 Class A GMDSS has a large full dot-matrix display which displays frequency or channel name. You can easily read the alphanumeric channel name, operating frequency, DSC setting, time, position, etc. In addition, dimmer and contrast level of the LCD are all adjustable to 10 different levels.
Powerful output power
A powerful 125W* (PEP) transmitter provides long distance communication you can rely on. A large aluminum chassis keeps the radio cool even during high duty cycle operation such as RTTY or E-mail operation.
*85W (PEP) between 1.6–3.999MHz
Simplified operation
All channels are grouped in 20 channel groups. Large independent group and channel knobs provide quick and easy channel selection. You can also directly enter a channel number from the 10-keypad.
General coverage receiver
Wide band, general coverage receive capability is available from 0.5 to 29.999MHz.
Numerous operating modes
The Icom M801 Class A GMDSS provides SSB, AM, CW, FSK and AFSK mode operation. The advanced DSP provides flexible filter settings and optional filters are no longer required for narrow band mode operation.
Versatile configuration
The controller and speaker are separated from the main (RF) unit. The supplied 5m separation cable or optional 10m separation cable (OPC-1575) can be used with the controller.
Rugged construction
The main unit is covered with a rugged aluminum casing, protecting internal parts from impact or salt corrosion. With the optional stainless steel one-action bracket, the main unit can be tightly installed or easily removed from a flat surface.
Voice squelch control
The VSC (Voice squelch control) function* only opens the squelch, when the radio detects voice componets contained in the signal, while ignoring noise or an unmodulated signal.
*J3E and H3E mode only.
Standard Accessories
Supplied accessories include the AT141GMDSS Automatic Antenna Tuner, seperation cable, HS98 Telephone Handset, SP24 External Speaker, mounting bracket kit, DC power cable, ACC plugs and spare fuses.
