The file 21MHz.JPG shows how 21MHz will be open typical for the month of
May and with a sunspot figure of 50 at 1500 hrs.
It contains three views of the world, one as a globe, one great circle
view and another Mercator projection world map.
The file is 18KB (crunched from 1Mb!) and is sent as 5 parts, max size 5kb.
The cruncher used was Irfan View.
I've been using propagation prediction software for a little while now
and I've been putting them to the test.
Using the VOACAP/ICEPAC engine I've found these maps really do work
*superbly*.
It's quite educational to study these maps and their variation from band
to band and time to time, as such I thought I'd send this sample piccy
for those of you not familiar with propagation software (yet!).
Note in the piccy the first clearly defined skip zone is evident.
Have fun.
