-Raspberry Pi 3 and Mobilinkd TNC2 for APRS duty

  • Setup XASTIR on Raspbian to act as an Igate using Mobilinkd KISS TNC.

XASTIR doing RF -> inet gating.  Terminal highlights commands to activate Bluetooth serial link after paired to Mobilinkd.

Update 6/2020 - Have been running an APRS Igate KL3RR-2 for about 1.5 years. Initially had some issues with bluetooth stability on the Raspi3.  The BT link would fail after a few weeks. I found this was a known issue and solved in the Raspi3 B. Indeed it fixed the problem and now has run stable for many months without any intervention.

Current hardware for KL3RR-2 is a Baofeng UV3R, Mobilinkd TNC2, Raspi3 B running Raspbian and XASTIR.  Antenna is an Arrow J-Pole at approx 30' height.

I appreciate the GUI of XASTIR both for visualization (which is a key outcome of the data produced by APRS) as well as being able to interact and use the station for APRS functions such as messaging.  Coupled with connecting to the raspi via VNC this makes for a functional APRS Igate that is remotely accessible and controllable.
