Setting up an APRS Digipeater with an Orange Pi Zero, Direwolf, and a Tait 8105

Several members of my local club M0HSL are experimenting with APRS and Packet Radio, so I thought I'd dip my toes in the water. The most common method is to use a Hardware TNC device and a radio aimed at amateur use, but I like doing things in software where I can ( and I'm a cheapskate )

I have used Direwolf in the past with an RTL-SDR dongle to receive APRS traffic, so I thought I'd give it a go with a physical radio, a Tait 8105. Unfortunately it's a UHF model, but the setup and programming is identical between the UHF and VHF version.

To control the handle the audio and PTT, I am using a modified CM108 USB sound fob.
