Just musing about APRS and trackers.
A tracker needs a GPS, some kind of data>packet gizmo and a radio. You can use radios like the Kenwood TH-D7 which just needs data from the GPS and you’re in busniess. Or you could go all 21st century and buy an ICOM DSTAR handy and GPS mike for about £800. (Lotsa wonga to talk to nobody!) Or you could wire a GPS to a small encoder and connect that to your handy. It all seems a bit Heath Robinson to me with wires running between stuff and anyway my GPS isn’t waterproof if you plug in a cable and it’s USB only and then you can’t clip on your belt either.
So the question is…
…if you could buy a package that was a complete APRS tracker and it had the following specification:
- runs for at least 12hours on 4AA cells
- has a self contained GPS (SiRFstarIII based)
- plugs straight into a handy
- socket for optional external mike
- intelligent software that beacons according to ground speed.
how much would you pay for that £30, £50, £70, £100?
