Daniele,
 
the two carrier segments certainly look right! Only the frequency stepping at 11:20 and 11:30 has apparently been covered by noise.
 
73, Markus

Could a very faint trace of a signal be found even in my attached capture? (very noisy location and very simple rx set, so little change it is a true signal).
Regards
Daniele

Stefan has fixed the PA problem and is getting > 1A antenna current. Today this requires only about 400 W input, due to favourable wet ground conditions.
 
The DFCW keying is somehow not working, so Stefan has basically transmitted a long carrier since 10:50. He has manually shifted the frequency down by 0.05 Hz at 11:20, and back up at 11:30.
 
Best wishes,
Markus

yes. The rain has ceased, and the kite is going up well. Stefan had a problem in his "big" PA, so since 10:15 he is using about 300 W from the smaller one. Antenna current about 0.6 A. Frequency measured here is 2.3 mHz below 8970 Hz.
