Ham Cap Question
- Alex and others,
As everyone knows, with Ham Cap the numbers from IonoProbe get plugged in
automatically. With the solar storm this past week it seemed to me that
propagation shown with Ham Cap did not reflect all the predictions during
So my question is this. Would Ham Cap better reflect propagation if it used
the 'Effective SSN' instead of the current SSN?
I only ask because I am not an expert in this area, I do find the Ham Cap
tool to be a valuable tool with my station when used with IonoProbe.
Thanks Alex for this interface,

Well, no & no. Ham Cap uses VOACAP as its calculation engine. VOACAP
is intended for making _statistical_ HF propagation predictions on the
monthly level. To be orthodox in this issue, this means that you
cannot use either the current SSN or Effective SSN. Why? Because
VOACAP has not been designed with these Sunspot Numbers in mind. For
