      stream data from the GPS directly out the port (bypassing the
      microcontroller), and use a mux to interrupt it to inject the KISS/
      APRS data?

      yeah, more hardware.

      One can only hope! Of course, you d think that APRS applications would ignore non-text PIDs too, but oh well. Oh, another argument for the synthesized NMEA

        Oh, another argument for the synthesized NMEA approach is that you could generate it from ANOTHER station's data, and use a mapping program to track that station.

        Forgive me, but:

        haha. Yeah, right!
