Signal 220 VHF Radio with Built-In AIS ReceiverBuilt-In AISStay aware of the water with built-in AIS receive capabilities. This feature shows you range, course, speed, and the crossing situation of other AIS-equipped vessels around you to help you navigate.Sleek DesignThe compact and modern design features edge-to-edge glass and takes up minimal space at the helm.Clear & Simple CommunicationEliminate unnecessary radio noise with automated squelch. If you miss a radio message, you can replay it with VHF audio playback. When you need to maintain watch on multiple channels, advanced watch modes make it easy.Stay ConnectedQuickly transmit a distress signal to nearby vessels with the distress button, which uses Class D DSC to automatically send crucial information that can help emergency responders. You can also use the intuitive DSC features to quickly initiate contact with other AIS-equipped vessels; simply select the vessel on the AIS plotter view, and call them with a tap of a button.Easy To UpdateConfigure the radio, program the MMSI number, and get over-the-air software updates with the ActiveCaptain smartphone app via built-in Wi-Fi connectivity.Installation Is A BreezeInstallation is simple since VHF/DSC/AIS features only require a single VHF antenna, and the GPS antenna/receiver is built into the unit.
