Hi Stefan and VLF 'ers ,
Good copy of the signals of DK7FC, JN06HT>JN49CE = 627km
(see attached copy) the error of frequency is due to the correction
of the sample rate of SpecLab was not corrected on the used PC!
My setup :
- Single turn loop CU ( 3m² )
- homebrew "A" class amplifier 30dB ( push pull of MMIC )
- Soundcard of laptop PC + Speclab
73 qro Jean-Pierre f1afj JN06ht

Running again. Signal strong enough for QRSS10, or at least 30 here.
Cheers,
Wolf .

Latest update at 12:25: Kite still up. But at 11:38 the generator ran out of fuel, and Stefan's still struggling to start her
up again. 73, Markus

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.
