I fail to understand why it is so blasted hard to get an answer on
anything on ham radio related forums. Why do people feel necessary to
give information totally irrelevant to the question? Why can't people
simply accept my question as it is, not tell me what my question should be?
I am trying to make a decision on buying a DRAWS Hat for the
RaspberryPi. I want to run various digital modes/applications including
MT63/PSK31/etc. with fldigi and APRS with Xastir.
My question seeks user experiences with these apps and DRAWS. Please
attempt to limit responses to that question.
Thanks,
Michael WA7SKG

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:
