Feed GPS position information from the SeaTalk NG network to an older VHF radio with Digital Selective Calling (DSC). Many 1st generation DSC radios need vessel position fix data in NMEA 0183 format to support their distress, safety and calling features. This kit reads NMEA 2000 GPS/GNSS information from the SeaTalk NG network and outputs NMEA 0183 sentences to support older DSC VHF radios.
