Beyond what others have mentioned like the TNC-Pi (nice kit), using a $7
USB soundcard and Direwolf will provide superior decodes. As for OS
images to run, that are packet centric, there are several available:
- Bernard's new Jessie based image for TNC-Pi -
http://f6bvp.org/AX25_BBS_Node_RaspBerry_Pi_install.html
- Mitch's Wheezy based image with setup GUI which supports TNC-X and
Direwolf -
https://sourceforge.net/projects/haldigital/
- I've been working on my own documentation for such a thing (v2 on
Jessie is close but incomplete, v1 for Wheezy is done) for Direwolf and
TNC-Pi -

- Brett's TNC-Pi centric image -

I'm sure there are others out there as well but these are the ones I'm
aware of at the moment.
