[Xastir] Xastir with DRAWS

[David Ranch]

NW Digital's DRAWS HAT boards is just a dual-channel soundcard with some 
PTT circuitry and a GPS.  There isn't anything really magical there 
beyond  very nice integration on one PCB for people who don't want to 
cobble something together themselves.  It also offers a good set of 
documentation and potentially offers more than just community support to 
get you going.

Your question probably should be more like:

    Is anyone using a souncard TNC like Direwolf, Tom Sailer's 
Soundmodem, etc. with Xastir vs TNC-Pi


I'm using Direwolf on an Rpi with a Syba USB sound device and it works 
very well.  It's TNC is generally able to dig out packet decodes that 
most PIC-based TNCs (like the TNC-X, TNC-Pi, etc) cannot.  The new 
TNC-Pi9k6 could be a different animal as it has a lot more CPU power but 
I haven't heard of any real decode comparisons yet.

The older Direwolf documentation used to have a comprehensive comparison 
table against other TNCs in the "10.1 WA8LMF TNC Test CD" section but 
newer versions dropped it.  Here is an example of it from the Direwolf 
1.3 docs.  Overall, Direwolf's decode performance has only gotten BETTER 
since then:
