[Moon-net] one-way propagation

["Heinz Bordé"]

Hi all
Last weekend several skeds failed because one-way propagation. W-stn copied every sequence but European stn had nil. Most guys have only H-polarised antennas and have to live with that. 
But I have x-pol and can react on that. But I´m not sure about how to do.
WSJT tells us the polarisation angel(VIEW-ASTRONOMICAL DATAS-DPOL). As far as I know:  DPOL ~ 45° means = one-way propagation.
If DPOL is so during a QSO between Stn A and Stn B, one stn will get a H-signal and the other one will get a V signal. But who will get what?
And because DPOL can be - or + : what does it mean for me?
Perhaps someone can tell me the law so I can react with my antennas to the values, WSJT (an even other moon tracking programmes as well) tells me.
