[SADXA] Propagation

[D Dismachek]

 It appears that Long Path to Europe is outperforming Short Path at higher frequencies. I noticed this during the CQ WW SSB contest recently. See VOACAP Online for Ham Radio for Phoenix to Berlin propagation forecast. Greater ionization in the atmosphere may increase the height of the F2 layer allowing bigger hops off that layer at higher frequencies.

 You're not alone.  I had the same situation happen this morning.  
European stations disappeared when the Yagi was set to a short path 
heading, but they reappeared when the antenna was rotated 45 to 90 
degrees further south.  It's like the whole ionosphere got twisted.  
Strange propagation.
