  • NMEA 2000 plug-and-play links GPS data and DSC calls
  • RAM4 second-station mic gives full radio and intercom control
  • Redesigned menu system makes DSC setup faster
  • Ultra-compact 3.3-inch depth fits tight dash spaces
  • White finish matches standard marine console aesthetics

Fixed-Mount VHF Radio with NMEA 2000

The Standard Horizon GX1850 is a fixed-mount VHF radio designed for marine communication. It connects directly to an NMEA 2000 network for plug-and-play GPS data and DSC calling between compatible devices. The ultra-compact rear case measures only 3.3 inches deep, simplifying installation in tight dash spaces. A redesigned menu system makes DSC programming and daily operation more intuitive.

Second-Station Microphone Support

This unit supports the optional SSM-70 RAM4 second-station microphone, model number 70, allowing full radio control from a secondary location. All functions, including DSC features and intercom between the main radio and the second station, are accessible remotely. NMEA 2000 connectivity means a single cable carries data to the network, freeing up dash space otherwise needed for separate GPS wiring. The shallow 3.3-inch depth also leaves more room behind the panel for other equipment.

Boaters Needing Compact NMEA Integration

This radio suits vessel owners who want a compact fixed-mount VHF with straightforward NMEA 2000 integration and the option to add a second-station microphone later. It is not suited for buyers who require a handheld portable VHF or a unit with built-in AIS reception, as those features are not included. Installers needing a deeper chassis for specific bracket hardware should verify the 3.3-inch depth against their mounting constraints.

Questions about this item

How deep is the GX1850 rear case for flush-mount planning?

The rear case depth is 3.3 inches, which is half the depth of many comparable VHF radios and allows flexible flush or bracket mounting in tight dash spaces.

What is the power draw on the NMEA 2000 bus when the radio runs all day?

The radio draws power from the vessel's NMEA 2000 backbone; typical receive current is low and transmit peaks are handled by the boat's DC supply, so continuous operation does not overload a properly sized N2K network.

Which second-station microphone works with the GX1850 for full remote control?

The Standard Horizon RAM4 model SSM-70 is the compatible second-station microphone that provides complete radio, DSC and intercom control from a remote location.
