[aprssig] Win APRS Mobile

Is the TNC board in the D700 the same as that in the DR-135?  Does anyone
know how the APRS functions integrate with the TNC?

I'm considering the possibility of building a version of my ARM-based TNC
that'd work as a drop-in replacement for at least the TNC in the DR-135.  If
the D700 is similar, I imagine it ought to be able to build an interface
layer that would correct some of the APRS behavior of the radio.  It could
be made to translate new message formats into those understood by the D700,
for example.

Just a thought...
