1803Re: [dxatlas] I miss some theory.
- Feb 27, 2010Hi Vytenis,
IonoProbe downloads the real time foF2 values measured by the network of
ionosonde stations, fits the mathematical model of the ionosphere to these
values, and computes SSNe, the effective SSN, that results in the best fit.
SSNe is then sent to DX Atlas and used to compute the real time map of
ionospheric parameters. However, this has nothing to do with propagation
prediction. Please note that the documentation that comes with the software
is more accurate than any third party reviews.

Probably I don't have some theory of radio waves propagation and miss some
point. About Ionoprobe. One of Radio waves propagation guru's Karl
Leutzelschwab K9LA in PVRC webinar
clearly stated that HF propagation has correlation to Smoothed Sunspot
Number (or smoothed SFI) and only to this number and any other number like
daily value has very little correlation to radio wave propagation. This was
illustrated with the graphs. Keeping that in mind, is it possible to apply
real time data to propagation prediction in HAMCap?
says DXAtlas shines in combination with Ionoprobe and taking Ionosonde data
and applying it to propagation calculations. That possibly would be good.
But although name implies, I do not see ionosonde data like foF2 or MUF
retrieved by Ionoprobe. Just SSN, SFI, Proton flux and Xray. Is
www.astrosurf.com stating wrong?
Please help me to understand
