How to

  • Download the .ogg file from the observation. The downloaded file will have a filename that looks like this: satnogs_ObservationNumber_YYYY-MM-DD-SomeMoreStuff.ogg
  • Convert the captured .ogg audio file to .wav. On a Linux command line, the conversion looks like this:
$sox satnogs_ObservationNumber_YYYY-MM-DD-SomeMoreStuff.ogg ObservationAudio.wav
  • Launch Fldigi
  • Click on File, Audio, Playback. Then select the .wav file.
  • Set Op Mode to CW
  • Adjust the center frequency to where the CW signal appears on the waterfall display.
  • Configure modems, CW, General. Set the BW and WPM to match the signal you want to decode. Save, close.
