Standard Horizon VHF's have DSC NMEA sentence output which will work
directly with their GPS plotters. You should be able to use the
Brookhouse multiplexer and make it work with any GPS plotter that
recognizes the WPL sentence.

Do you mean a device that listens for DSC and then transmits that data via
serial or USB? As in, a listener for your PC that would pickup any DSC data
it hears.

Do any of the existing VHF radios that have NMEA interfaces do this?
