Five out of six transmissions were copied in Nuernberg:
 
 start   carr.  sym.
   UT    dB      dB
18:00   (garbage)
18:30   6.7   3.5 
19:00  10.3  8.2 
19:30   7.1   4.2 
20:00   8.3   4.8
20:30   5.3   2.6 
The 19:00 transmission happened to have a nearly perfect phase evolution (attached), whereas the other ones were mostly limited by ionospheric variations rather than SNR.
 
Best 73,
