Hi Mike,
Strongest copy so far on Pehuensat-1.
Trying MixW for the decode.
What settings do you suggest, perhaps you could post them on the bb?

Hi John,
yes of course:
MixW Mode: Packet
Mode Settings: -> Modem -> VHF Custom AFSK
Baudrate 1200
Tone1,Hz: 1200 (or analyzed frequency)
Tone2,Hz: 2400 (or analyzed frequency)
The best way is to record the pass and analyze the wav file later.

Hi Mineo,
first of all you must analyze the two AFSK frequencies (Mark and Space).
I'm not sure but I think this was 1600Hz and 2800Hz in your wav file.
With these frequencies you shall decode your file.
There are no more other settings.
If you need further help, please feel free to ask me everytime :-)
73, Mike

Hi Mike,
Thanks for your Telemetry Analysis from my sound of PehuenSat-1.

But I could not decode my sound,

Are there more the other settings ?
I could decode finally my sound with MixW2 !
