Description
The Simrad RS20S packs full Class D Digital Selective Calling into a compact, easy-to-fit fixed-mount VHF radio. A built-in GPS receiver and antenna mean your latitude, longitude and time are always available, and your position is automatically attached to DSC distress calls without relying on any other equipment. A separate built-in CH70 receiver keeps a constant watch on the digital distress channel while you use the radio normally.
Day-to-day operation is straightforward, with a four-key hand mic and built-in speaker, switchable 25 W or 1 W transmit power, dual and tri-watch scanning, weather channels and a dedicated distress key. NMEA 2000 and NMEA 0183 connectivity let the RS20S share GPS data with, and take position from, the rest of your onboard network, while submersible IPx7 construction makes it dependable in an open helm.
