What are the key features of the Standard Horizon Quantum GX6000 VHF radio?

The Standard Horizon Quantum GX6000 offers a powerful 25W transmission, integrated AIS receiver, NMEA 2000 compatibility, and a built-in voice scrambler. It also features an integrated PA/loud hailer, wireless remote control, and collision avoidance alarms, making it ideal for commercial and recreational vessels.

How does the AIS receiver in the GX6000 enhance navigation safety?

The integrated AIS receiver displays real-time AIS target information such as MMSI, ship name, bearing, distance, speed, and course on the front panel, helping you identify nearby vessels, avoid collisions, and improve navigational awareness.

Can I control the Standard Horizon GX6000 remotely?

Yes, the GX6000 supports wireless control through the RAM4W wireless remote microphone, allowing you to operate all radio functions up to 65 feet away, including DSC calls, group calling, and intercom functions.

Is the GX6000 compatible with my existing marine electronics network?

Absolutely! The GX6000 features plug-and-play NMEA 2000 and NMEA 0183 compatibility, enabling seamless integration with your existing navigation systems, GPS, AIS, and DSC equipment.

What accessories and support are included with the purchase of the GX6000?

The package includes the GX6000 VHF radio, hand microphone, power cord, mounting bracket, USB cable, and the owner's manual. It also comes with a 3-year waterproof warranty for added peace of mind.

What are the key safety and communication features of the Standard Horizon Quantum GX6000?

The Standard Horizon Quantum GX6000 offers advanced safety and communication features, including a 25W loud hailer system with programmable foghorn signals, integrated AIS receiver for vessel tracking, dual-channel AIS connectivity, and NMEA 2000 integration for seamless network communication. It also includes programmable collision alarms and a voice recorder for enhanced situational awareness and secure conversations.

How should I set up antennas and GPS to ensure full functionality of the GX6000?

The GX6000 requires two antennas: a standard VHF antenna and a dedicated AIS antenna or splitter for optimal performance. It does not have an internal GPS, so you'll need to connect an external GPS source via NMEA 2000, 0183, or the optional SCU-31 external GPS antenna to enable DSC distress features and navigation functions.

Standard Horizon Quantum GX6000 25W Commercial Grade Fixed Mount VHF – NMEA 2000 & Integrated AIS Receiver

The Standard Horizon Quantum GX6000 is a professional-grade fixed-mount marine VHF radio engineered for demanding commercial and recreational applications that require advanced communication, safety awareness, and seamless network integration. With 25 W transmit power, an integrated dual channel AIS receiver, and NMEA 2000 connectivity, this robust radio brings powerful performance and marine intelligence to your helm station.

Designed for serious boaters and commercial operators, the Quantum GX6000 displays comprehensive AIS target information — including MMSI, call sign, ship name, bearing, distance, speed and course over ground — helping you track nearby vessels and enhance situational awareness on busy waterways. The plug-and-play NMEA 2000 interface seamlessly integrates with onboard navigation networks, feeding DSC, AIS, GPS, and channel data to compatible chartplotters and multifunction displays.

This radio goes beyond basic communication with a 25 W PA/loud hailer system complete with programmable foghorn and “bells and whistles” signals, plus a voice scrambler for secure conversations. An intuitive E2O Easy-to-Operate menu system, oversized rotary channel knob, and waterproof front panel make operation simple even in rough weather.

The Quantum GX6000 also supports optional wired or wireless remote microphones and includes advanced features like programmable CPA collision alarms and an integrated voice recorder that captures received audio. Built to withstand rugged marine environments with a robust IPX8-rated design, this radio is ideal for offshore cruising, commercial fleets, and professional vessels.

Key Performance Features

Integrated AIS Receiver: Displays AIS targets (Name, MMSI, BRG, DST, SOG, COG) directly on the screen with programmable CPA (Closest Point of Approach) collision alarms.
Continuous Duty AIS: Unlike combined units that share an antenna, the GX6000 features separate VHF and AIS antenna connectors, ensuring AIS data is never interrupted during VHF transmission.
NMEA 2000 & 0183 Connectivity: Fully supports all PGNs for Navigation, GPS, AIS, and DSC. It plugs directly into your NMEA 2000 backbone to share target data with your chartplotter.
Integrated Voice Recorder: Automatically records up to two minutes of received audio, so you can replay a missed transmission or coordinate instructions.
25W Loud Hailer / Fog Horn: Includes a powerful 25W PA system with pre-programmed fog signals (Bells, Whistles, Horns) and "Listen Back" capability.
Multi-Station Expandability: Supports up to two wired RAM4 (SSM-70H) microphones or up to four wireless RAM4W microphones (requires optional SCU-30 wireless access point).

Dual Antennas Required: For full functionality, the GX6000 requires two antennas: one standard VHF antenna and one dedicated AIS antenna (or a high-quality AIS splitter).
External GPS: The GX6000 does not have an internal GPS antenna. It must receive GPS data from your NMEA 2000 network or the optional SCU-31 external GPS antenna to enable DSC distress features

Are you setting this up with a second station?

If you want to control this radio from the flybridge or cockpit, you'll need the RAM4 Wired Mic or the RAM4W Wireless setup. I can help you list the specific parts (like the SCU-30 hub) required for a wireless installation.

The Standard Horizon Quantum GX6000 25W Commercial Grade Fixed Mount VHF is a top-tier marine communication solution — combining robust performance, networked connectivity, AIS awareness, and advanced safety features in one professional-grade unit.
