FAQ
===

  Q: Why is my decoded image slanted?
  A: Sample rate mismatch. Use 44100 Hz
     or let the app resample.

  Q: Can't detect my SSTV signal?
  A: VIS code must be at the start.
     Try "Force Decode" for partial
     recordings.

  Q: What's FSK ID?
  A: Transmits callsign as digital data,
     compatible with MMSSTV.
