When I first heard about APRS, I had hoped I could use it to replace tracking I already get from my SPOT device. I began my learning curve by testing several APRS apps.
Yesterday I put APRS-IS to the test in the mountains on the San Juan Trail, located a few miles way from Ortega Highway 74. In this area there are no digipeaters close enough for RF transmissions, so I tested the SPRINT cellular network to see if I could be tracked in real time (KM6ZPO).
