Dear Paul, Wolfgang,
 
thank you very much for sharing your= results! This=20 is an excellent confirmation.
 
I'm still amazed at the day to day ph= ase=20 reproduciboility, which seems to be only a fraction of a cycle over a= 27 Mm,=20 mostly nighttime path.
 
The depth of the nulls indicates that= the two=20 components happen to have almost equal amplitude. It would be interesting to try the other wa= y round, ie. look at eg.=20 GBZ from down under! If the relative long path contribution was= =20 much less there, we could conclude that east-west=20 nonreciprocity does indeed play a role, and the "upwind" path doe= s suffer=20 more attenuation. 
 
Steve VK2ZTO, are you still reading= this=20 reflector?
 
Best wishes,
Markus
