Hello Stefan,
think i copied your transmission today. I received a
signal */- 6469.97 from around 16-17:30 local (CET) time.
I used a Miniwhip antenna with SpectrumLab Qrss120,
2.0mHz.
My locator JN49ax44, so QRB to you
53Km.
Not see anymore a signal and stop my RX
now.
thanks for your signal - very
amazing...

Dear LF/VLF group,
It took a long time to get a proper wind
forecast in a time sector where i can do a kite experiment. Also it took a long
time to get the special permission for the new kite antenna.
But now,
if the wind will be enough and if there is no rain on Sunday, the 1.
August, i will make a new kite experiment.
The first time i will try
to use a 200m vertical antenna and 600W TX power. The L of the loading
coil will not be reduced in this experiment and so i will transmit at arround
6,5 kHz, the 46 km or 47 km band! This is since i do not yet know the
actual antenna C (EZNEC says 972 pF). The ERP will be arround 16 mW
(first estimation). This is about 10 dB more than in the first and successful
2nd experiment on March, 15th. Also it is said that propagation on 6 kHz is even
better than on 9 kHz! The first time it could be realistic to reach the 1A
antenna current mark!
Since some weeks i have set up a grabber in
DFCW-120 mode (just to cover a broader frequency range) at http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html
If you want to catch my signal, you can look there where i am actually
transmitting. After some resonating tests i will transmit in good old
DFCW-600, so it is the best you use a 3...5 mHz FFT and about 1 minute per
pixel.
Starting time is 8 UTC, maybe some time later since it is
the first experiment with such an antenna! I still do not know if big problems
will occur but i am a DREAMER (remembering the 3rd experiment: http://abelian.org/vlf/ss100321/ ).
But don't be disappointed if it would be failed. Actually it cannot fail since
there will be found improvements for the next test!
TX QTH is as usual in
JN49IS, 49.77647N 8.699525.
The summer time and maybe day time may be not
the best but it is an important test for the winther period. Maybe we will see
some surprises depending propagation on arround 6 kHz. And it will be the first
time that an amateur reaches the far field and hopefully more than 1 Lambda on
such a low frequency :-)
Any RX reports and ideas/hints (before and after
the test) are very appreciated!
Best 73, Stefan/DK7FC
*excited*
