I'd like an APRS setup for my ft-8800 spelled out in dummy terms. What do I need to make it work (TNC, cables, GPS, etc), and where do I find such items? For the GPS antenna I thought about using a GPS tracker that I could put under my dash (where I have my satellite radio antenna). Good idea or no? I understand limitations from the ft-8800, but I'd like to try. Something that isn't visible to the passer-by, but still broadcasts my location when I get in the car.
