Congrats to the AO-85 team!

Trying to decode telemetry using the 9600 output of the sub data (while 
radio is in Sat mode) from my IC-910H.  Has anyone been able to do 
this?  High elevation passes only?

9600 output is connected directly to mic input.  No isolation 
transformers, etc.  Seems like those making progress have gone the SDR 
route with IQ data?

Sound card input - 2 channel (L-R channels connected on cable), 24 bit, 
48000 Hz

radio - cable to sub band data socket.  9600 bps transmission on. (Is 
this for TX only, does not change output and  can be left of?)

AO-85 software

Source - mic input, 4800

start --> no joy,

Suggestions welcome.

Thanks, es 73
