I try to calculate a "DX Index" the DXI for JO33HG
A simple calculation to start with:
I take 100 WSPR spots of the last 12 hour period.
Ordered by DX ascending. calculated for my location.
Unique calls check can not be used with multyband.
The number count of DX >5000km is the "DXI" for my location:
26 December morning the DXI was 40 for bands 500/160/80
26 December evening DXI was 54 including 10/15/20/40
27 December morning 06UTC the DXI has dropped to 10!
It is a start and gives some indication.
But it can use improvement by weighing the doubles into the figure
Now the activity is a major factor.
That means it is not representative outside EU and USA since WSPR is rare in the rest of the world. Why some HAM's never try WSPR in a DX location like FK8 VP8 but just leave their expensive radio's unused?? it is a mystery to me.
and the one and only DX on 500kHz
