 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.
