An unknown satellites that is launched with Transporter 8 and active on 436.630 The data comes from the following observation: https://network.satnogs.org/observations/7748376/ After trying multiple FSK combination with gr-satellites I am unable to decode the signal. (I wish that in the meantime I was able to do a more indepth analyses, but I am stuck.) Listening and looking at the frames I get the impression it is AX100. In the directory are two files, one is the rawint16 of the observation and the other is a recording of the NFM demodulation of the rawint16 (replay with SDR#) IQ rawint16: iq_48000_7748376.wav Stereo AF demodulated: af_48000_7748376.wav
