The usual scheme is that the GPS receiver feeds its data to the
TNC (in my case, a Kantronics KPC-3+), and the TNC interfaces with the
radio involved to move the data. APRS, as its name implies, is mainly
for position reporting.

But if I'm using a Palm Pilot, how does the Palm Pilot interface with the TNC?
Do you need a splitter so both can plug into the TNC? Can you recommend a GPS
unit that will do what I need? It's going to be a mobile setup, but doesn't
need to be the top of the line.
