Doesn't the Microtracker (mentioned in your sig) take coax s/pdif? If so, with the MT you wouldn't need the HOSA.
That's one config I'm going to try this afternoon. konnekt8 > hosa odl-276 > jb3 @ 48/16
I don't have a spare battery for the konnekt8 yet so it'll still be on the wallwart but that should test the settings recall.
