Thanks Paul,

Terrible, it becomes worese again :-( Quite a struggle. But i (we) need 
to stay relaxed.
The 4th transmission is now running. Let's see what it brings.

It would be interesting to learn and predict the phase. Why do these 
changes happen? Just by chance?
The first two nights were quite stable but why is the second almost in 
opposite phase?
73, Stefan
