[SADXA] Propagation

[Lawrence Godek]

I noticed that on 10M as well.  Couldn't figure where to point the 
antenna as stations all over the place were being worked with the beam 
pointed to the NE at about 30 deg.  Maybe there is more going on than 
what we understand or suspect?

I notice also that 40M goes dead (here anyway) for a while starting 
around 9 am.  I usually hear the Texas Traffic Net on 7290 LSB every day 
quite strong.  Lately they have been absent and they never miss a 
day/session.  They usually start around 8 or 9 am our time.

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.
