Simrad RS20S Marine VHF Radio w/ DSC 000-14491-001

Simrad RS20S Marine VHF Radio w/ DSC

The Simrad RS20S (Part Number: 000-14491-001) is a high-visibility, fixed-mount Class D DSC (Digital Selective Calling) Marine VHF Transceiver. Engineered for versatility on powerboats, sportfishers, and commercial vessels, it combines clear radio communication with an integrated internal 4-channel GPS receiver (1575.42 MHz) to transmit precise distress coordinates without requiring external GPS input.

Featuring a high-contrast inverted dot-matrix display, intuitive rotary dial control, and a dedicated distress button, the RS20S seamlessly interfaces with vessel networks via NMEA 2000® (Micro-C) and NMEA 0183®. The "-S" updated variant incorporates built-in internal GPS antenna hardware while maintaining full compatibility with external GPS antennas (such as the Simrad GPS-500) for enclosed aluminum/steel helm installations.

Key Features

• Built-in Internal GPS Receiver: Four-position internal GPS antenna provides location data directly to DSC emergency distress functions out of the box.

• Class D DSC Compliance: Dedicated Channel 70 receiver continuously monitors for emergency distress calls while operating on active voice channels.

• Dual & Tri-Watch Functions: Allows simultaneous monitoring of working channels, Channel 16 (Emergency), and Channel 9/Call channel.

• NMEA 2000® & NMEA 0183® Integration: Easily shares GPS position, vessel data, and DSC distress calls across Simrad MFD networks.

• Sleek Low-Profile Design: Front-mount design matches the low-profile "glass bridge" dash styling of Simrad NSS, NSO, and GO displays.
