MF/HF MARINE TRANSCEIVER

Meets GMDSS requirementsThe IC-M801GMDSS is designed forClass A DSC operation. With the op-tional AT-141 antenna tuner, it pro-vides a complete GMDSS MF/HFcommunication system as required forCommercial Solas regulated vesselsvoyaging in the A2 sea area. Theradio also meets MED 96/98/EC,“wheel mark” requirementsfor European merchantships.

Built-in ITU Class A DSCAn independent DSC receiver con-stantly watches MF/HF DSC chan-nels, while using another channel. TheDSC allows you to call intendedship(s) or coast station(s) directly aswell as all ships in the geographicarea. A total of 100 MMSI IDs can bestored with a 10-character name. Inaddition, the self test function allowsyou to check the DSC functions.

Built-in DC-DC converterThe IC-M801GMDSS has a built-inDC-DC power converter, which pro-vides stable 13.6V DC converted froma 24V DC power supply. A floatingground system is employed.

Optional automatic antenna tuner, AT-141The optional AT-141, automatic an-tenna tuner, tunes all frequencies in allmodes. It easily connects to the IC-M801GMDSS with the optionalshielded cable. If the tuner cannottune the antenna, the IC-M801GMDSS bypasses the tuner and dis-plays an alert on the display.

Large LCD with full dot-matrix charactersThe IC-M801GMDSS has a large fulldot-matrix display which displays fre-quency or channel name. You caneasily read the alphanumeric channelname, operating frequency, DSC set-ting, time, position, etc. In addition,dimmer and contrast level of the LCDare all adjustable to 10 different levels.

Powerful output powerA powerful 125W* (PEP) transmitterprovides long distance communicationyou can rely on. A large aluminumchassis keeps the radio cool even dur-ing high duty cycle operation such asRTTY or E-mail operation. * 85W (PEP) between 1.6–3.999MHz

Simplified operationAll channels are grouped in 20 chan-nel groups. Large independent groupand channel knobs provide quick andeasy channel selection. You can alsodirectly enter a channel number fromthe 10-keypad.

General coverage receiverWide band, general coverage receivecapability is available from 0.5 to29.999MHz.

Numerous operating modesThe IC-M801GMDSS provides SSB,AM, CW, FSK and AFSK mode opera-tion. The advanced DSP provides flex-ible filter settings and optional filtersare no longer required for narrowband mode operation.

Versatile configurationThe controller and speaker are sepa-rated from the main (RF) unit. Thesupplied 5m separation cable or op-tional 10m separation cable (OPC-1575) can be used with the controller.

Rugged constructionThe main unit is covered with arugged aluminum casing, protectinginternal parts from impact or salt cor-rosion. With the optional stainlesssteel one-action bracket, the main unitcan be tightly installed or easily re-moved from a flat surface.
