[Xastir] Xastir on pi3 with kpc3 plus

[Lee Bengston]

APRX works well as an igate and/or digipeater, and it's very small thus
putting a very light load on the Pi. I have an old model B, though, so your
Pi3 may not care as much about that. I also run ldsped on the Pi so other
APRS clients can access the radio/TNC.

I have 2 prolific based usb to serial adapters. Both would eventually
freeze up after continuous use on a 7x24 igate. Switching to an FTDI based
adapter fixed that. Lastly I think the Pi3 has its own sound chip, so
DireWolf may be a good solution for a TNC, and it also supports igating.
