Configuring the Anytone 878 and Pi-Star to pass and receive APRS traffic for either Digital APRS or Analogue APRS can be a bit challenging. There are youtube videos; some are good, some are not. I watched many :-). I decided to piece together the best of what I watched and read to help me remember what I learned. I am getting older and being able to retain configuration I do infrequently posses a challenge.
I hope this guide (see attached) provides you with the necessary information to configure your Digital APRS and Pi-Star successfully. Hope to see you on http://aprs.fi .
