[aprssig] Thinking about YAAC

For mobile use I will be using an RPi 3B+ with a TNC-Pi, so I won't need
Direwolf in that application. The TNC-Pi will provide an adequate
interface between the radio and computer.
For the base, I have a Linux desktop computer running Mint currently
connected to an MFJ-1274 (MFJ-1270B with tuning indicator) to the radio.
If I were to use Direwolf on the base, I would need to add a soundcard
and homebrew some kind of interface for the PTT as well as fabricate new
cables. Right now, I have a very simple configuration with a single
serial cable going to the TNC and a single cable going from the TNC to
the radio and it all works very well. At least with Xastir. With YAAC,
however, I get nothing displaying on the map. In the configuration
window for the interface where it has the TEST PORT button, I see plenty
of data coming in from the TNC. Just nothing displays on the map or in
the RAW DATA window.
