Class E DSC, a bright 4.3-inch color display, and a built-in GPS put ship-to-shore voice, digital distress, and HF email in one package. IPX7 waterproof remote head. Offshore communication done right.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Icom M803 is the long-range single side band radio for cruisers who plan to sail past the reach of VHF and cell coverage. It's an MF\/HF transceiver that pulls in both marine and ham frequencies, with continuous receive coverage from 500 kHz all the way to 29.9999 MHz. If you're heading offshore, across an ocean, or just far enough out that a handheld won't cut it, this is the radio that keeps you talking to other boats, coast stations, and shore-side nets.\u003c\/p\u003e\n\u003cp\u003eClass E DSC MF\/HF certification is the heart of it. Press the dedicated Distress button and the M803 sends an automated digital distress call with your GPS position, calling for help from any ship or coast station in range. The radio runs a separate DSC watch-keeping receiver that continuously scans the six distress channels in rotation, so it's always listening even while you're using the set for something else. You can store 100 MMSI numbers, 75 individual and 25 group, each with a 10-character name. And if a second DSC call comes in while you're already working one, the Multiple Task Mode lets you hold both and switch between them.\u003c\/p\u003e\n\u003cp\u003eThe 4.3-inch color TFT display is bright and easy to read, with a viewing angle close to 180 degrees. That matters at a nav station or a bulkhead mount where you're rarely looking at the screen head-on. A night mode keeps it readable in the dark without wrecking your night vision. Operation runs through a big main dial and a row of software keys along the bottom of the screen, plus an alphanumeric keypad for punching in channels, MMSI numbers, and vessel names. If you already run the Icom M605 VHF at your helm, you'll feel right at home. The two share a front-panel layout and user interface on purpose, so you're not learning two different radios.\u003c\/p\u003e\n\u003cp\u003ePosition data comes from a built-in GPS receiver that uses GPS, GLONASS, and SBAS, fed by the supplied GPS antenna on a 5-meter cable. Your position, course, speed, and UTC time show right on the radio, and that data can go out the NMEA 0183 port to a plotter or other instruments at 4800 to 38400 bps. On the receive side, an RF direct sampling system sharpens sensitivity and cleans up audio, and the Instant Replay function automatically records incoming audio so you can play back a call you missed.\u003c\/p\u003e\n\u003cp\u003eFor a lot of cruisers, HF email is half the reason to carry an SSB. The M803 stores up to 160 email frequency channels along with the mode and bandwidth for each, and it has connection terminals for a PC and an email modem. Wire in a data modem and you've got weather files and email from the middle of nowhere.\u003c\/p\u003e\n\u003cp\u003eA word on the install, because an SSB is only as good as the ground and antenna behind it. Plan on heavy DC wiring run straight to the battery, 4 to 6 AWG, to hold voltage under a 30-amp transmit load. You'll want an automatic antenna tuner mounted close to the antenna feedpoint, an insulated backstay or a dedicated whip for the antenna itself, and a real RF ground tied to the sea. Skimp on the ground and you'll chase RF noise through your autopilot and instruments. Keep the control cable and antenna coax away from your NMEA and data runs to keep digital noise out of the audio. It's more work than bolting up a VHF, but done right it's rock solid.\u003c\/p\u003e\n\u003cp\u003eThe M803 controller is IPX7 waterproof, good for a meter of water for 30 minutes, so a wet nav station or an open pilothouse won't bother it. This is a serious piece of offshore gear for blue-water sailors, long-range trawler owners, and anyone who wants dependable communication when land is a long way off. It's not what you need for a day on the bay, that's a VHF job, but for going over the horizon it's exactly right.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e150 W PEP maximum RF output, selectable down to 100, 60, or 20 W for long-range MF\/HF voice and data\u003c\/li\u003e\n  \u003cli\u003eClass E DSC MF\/HF certified with a dedicated distress button that sends your GPS position automatically\u003c\/li\u003e\n  \u003cli\u003eContinuous receive coverage from 500 kHz to 29.9999 MHz reaches marine and ham bands alike\u003c\/li\u003e\n  \u003cli\u003e4.3-inch color TFT display with a nearly 180-degree viewing angle and a night mode for low light\u003c\/li\u003e\n  \u003cli\u003eBuilt-in GPS, GLONASS, and SBAS receiver supplies position, course, speed, and UTC, with output over NMEA 0183\u003c\/li\u003e\n  \u003cli\u003eIPX7 waterproof remote controller handles 1 meter of water for 30 minutes\u003c\/li\u003e\n  \u003cli\u003eStores 100 MMSI numbers, 75 individual and 25 group, each with a 10-character name\u003c\/li\u003e\n  \u003cli\u003eUp to 160 HF email frequency channels with PC and modem connection terminals for offshore email and weather\u003c\/li\u003e\n  \u003cli\u003eRF direct sampling system improves receiver sensitivity and audio clarity\u003c\/li\u003e\n  \u003cli\u003eInstant Replay automatically records incoming audio so you never miss a call\u003c\/li\u003e\n  \u003cli\u003eNMEA 0183 Version 4.10 data input and output at 4800 to 38400 bps\u003c\/li\u003e\n  \u003cli\u003eMultiple Task Mode holds two DSC calls at once so you can switch between them\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Icom reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow much power does the Icom M803 put out?\u003c\/summary\u003e\n    \u003cp\u003eUp to 150 watts PEP, and you can dial it down to 100, 60, or 20 watts depending on conditions and how much current you want to draw.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes the M803 have built-in GPS?\u003c\/summary\u003e\n    \u003cp\u003eYes.
