To what do you attribute the changes in tuning using the higher Q litz wire?
I mean when the wind blows

Is it movement in the antenna wire itself? Or
is it an effect of the air/moisture,temp. change passing over the coil?

Yes one factor, when the wind blows and causes antenna wire movement because the
Q is very hight for litz wire and the bandwidth therefore is quite narrow, the
antenna goes off resonance, and not good for the PA, you could easily Zap the
transistors. Because of over all losses using small antennas on LF the advantage
of using litz is only marginal over convential 2- 3 mil insulated wire.
