I have been interested in APRS for many years now, but have not made the leap yet. But now I think I might. I ordered a Mobilinkd TNC2.1 and am currently waiting for it to arrive. It looks to be a simple way to connect and use APRS. I am planning to connect it to an Android tablet and a handheld radio. I will put this in my truck and be APR ready if it works out. I will update when I get it and as I set it up and use it.
