Luis,
I wish I had an answer for you. All I can say is you're the
victim of "ionospheric weather", very changeable.
Seriously, I am convinced there is a meteorological factor in
propagation, from the winds and atmospheric motions in the D-E
transition region. Since ions and electrons have high collision
rates with the atoms and molecules up there, they are carried
along = rising, falling, tilting - as the atmosphere moves about.
And the atmosphere does move, being seen from time to time in
meteor and rocket trails. But more convincing is the fact the
atmosphere's composition is thoroughly mixed up to the turbopause,
around 90 km. With all the turmoil below, I cannot believe the
atmosphere is in static equilibrium. Our problem is the lack of
observations up there. But maybe some sharp-eyed meteorologist
will spot a clue and start to untangle the problem.
In the meantime, hang in there and work all the DX you can.
73,
Bob, NM7M
