The GX1850 is a 25-watt fixed-mount VHF transceiver built for marine use, designed for reliability and “plug-and-play” integration with modern boat electronics. It supports Class D DSC (Digital Selective Calling) per ITU-R M.493-13, with a dedicated CH70 receiver — meaning it can continuously monitor distress and safety calls on channel 70 even while you’re talking on other channels.

It’s engineered for compactness: the rear case depth is just 3.3" (≈ 82 mm), making it much slimmer than many other fixed-mount VHFs — handy for flush-mounting on a crowded dash or fitting in tighter spaces.

On the connectivity front, it offers both NMEA 2000 and NMEA 0183 interfaces, facilitating integration with GPS/chartplotters and other navigational gear. If you connect a compatible GPS/chartplotter, the radio can display important navigation data (latitude/longitude, speed over ground, course over ground) as well as a compass and waypoint information.

Other user-friendly touches: the unit uses an “E2O” (Easy to Operate) icon-based menu system for simple control, lets you store up to 10 favorite channels for quick access, and supports features like programmable scanning, priority scan, NOAA weather channels with alerts, and even a night-mode display for low-light operation.

Overall — the GX1850 balances performance, connectivity, and ease of use in a compact, install-friendly package, making it a solid choice for small to mid-size boats that require a dependable fixed VHF with DSC and networked navigation compatibility.
