From?reading your post it seems it's the computer software that's letting you down NOT the hardware?? If so, the subject line sure is misleading - the subject line makes it sound as if it's the hardware.? Yet, later in your post you say the hardware is good.? Why not put "TinySA computer software" as the subject line as that seems to be the issue.
I'm looking for a Linux version of software for the TinySA to use - maybe I just need to look more.??
