      Hi Patrick,

      It does not make much sense to use SSNe from IonoProbe in HamCap.

      IonoProbe calculates the effective SSN by fitting the latest IRI-2001
      ionospheric model to the real time ionosonde measurements. In other words,
      the SSNe makes this particular model to agree with the actual state of the
      ionosphere. If you enter this SSNe in another model, such as the old model
      used in VOACAP, this may result in inaccurate predictions.

      Please note that iono map in DX Atlas is also based on IRI-2001, and the use
      of SSNe from IonoProbe greatly improves its accuracy.
