   S-O-L-V-E-D !!!

Grabbed the scope and tried to find the signals. Got none. 
Found out: Data-out on the Xbee adapter PCB doesn't have a connection to the 
The connector has two rows of contacts, so I shifted the Xbee to the left row 
of the connector, leaving the right side (pins 11 to 20) unconnected. 
And - voila - the GCS populated and the messages window showed something. 

Well, after a few minutes, the Paparazzi software didn't react any more and had 
to be forced to quit. Restarted the software, the signal bars of the GPS are 
gone and the GPS is stuck at accuracy level of 12.4m. Get lots of 
"WAYPOINT_MOVED" messages in the paparazzi center. So, maybe, this is the duty 
cycle problem. 

But it looks a lot better than yesterday.
