Onderwerp: VLF: DK7FC's 6t= h VLF kite=20 experiment

Dear LF/VLF group,

It took= a long time=20 to get a proper wind forecast in a time sector where i can do a ki= te=20 experiment. Also it took a long time to get the special permission= for the=20 new kite antenna.

But now, if the wind will be enough an= d if there=20 is no rain on Sunday, the 1. August, i will make a new= kite=20 experiment.

The first time i will try to use a 200m vert= ical=20 antenna and 600W TX power. The L of the loading coil will not= be reduced=20 in this experiment and so i will transmit at arround 6,5 kHz,= the 46 km=20 or 47 km band! This is since i do not yet know the actual ante= nna C=20 (EZNEC says 972 pF). The ERP will be arround 16 mW (first= =20 estimation). This is about 10 dB more than in the first and succes= sful 2nd=20 experiment on March, 15th. Also it is said that propagation on 6= kHz is even=20 better than on 9 kHz! The first time it could be realistic to reac= h the=20 1A antenna current mark!

Since some weeks i have set= up a=20 grabber in DFCW-120 mode (just to cover a broader frequency range)= at http://ww= w.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html= =20 If you want to catch my signal, you can look there where i am actu= ally=20 transmitting. After some resonating tests i will transmit in go= od old=20 DFCW-600, so it is the best you use a 3...5 mHz FFT and about= 1 minute=20 per pixel.

Starting time is 8 UTC, maybe some time= later since=20 it is the first experiment with such an antenna! I still do not kn= ow if big=20 problems will occur but i am a DREAMER (remembering the 3rd= =20 experiment: http://abelian.org/vlf/ss100321/=20 ). But don't be disappointed if it would be failed. Actually it ca= nnot fail=20 since there will be found improvements for the next test!
TX QT= H is as=20 usual in JN49IS, 49.77647N 8.699525.

The summer time and ma= ybe day=20 time may be not the best but it is an important test for the winth= er period.=20 Maybe we will see some surprises depending propagation on arround= 6 kHz. And=20 it will be the first time that an amateur reaches the far field an= d=20 hopefully more than 1 Lambda on such a low frequency :-)

An= y RX=20 reports and ideas/hints (before and after the test) are very=20 appreciated!
