I download audio via https://network.satnogs.org/observations and convert ogg to 16 bit pcm stéréo 48k wav file with audacity. Then I decode using multipsk, convert bmp to png and rename file data-[id_observations]-[date_heure_obersations]_[number_of_image].png. Upload files to satnogs station, give file right to satnogs user and move to /tmp/.satnogs/data.

Thank you for these instructions! I just used them for this observation:
