Hi Markus, Stefan, and all,
It appears that you have things working reasonably well in JT9-1. Here
are the decodes Markus received from Stefan:

What happened between the transmissions at 1936 and 1940? The measured
clock offset DT changed from about +1.5 s to nearly zero. (Note that
+1.5 s is an unusually large offset, possibly indicating a problem. In
general, with good NTP synchronization at both ends, DT should be nearly
constant and in the range +/- 1 s.)
