Hello group,

Short information from Stefan, DK7FC.

Unfortunately their was some rain and big clouds over his QTH= , but now it looks better include the actual weather forecast in the internet.= This causing some delays, but Stefan is now in the middle to bring up the antenna. He estimated a start time around 10am CET =E2=80=93 so in about 30-= 40min.

Dear VLF group,

Now, the wind forecast shows excellent wind for tomorrow and unstable and po= or wind for sunday. So i will do the 11th experiment tomorrow, Saturday, 18.= June 2011.

Tnx in advance to Markus/DF6NM who will be available on the phone to mak= e QSP to the LF reflector.

Dear VLF group,

Since more than 4 months the wind and rain situation looks promising for the= weekend on my /p QTH in JN49IS36VH. So i plan to do my 11th VLF kite experiment this weekend, either on Sat 18th or Sun 19th June 2011= , will be announced on friday. I already announced it at the German air traffi= c control and just got a phone call were the permission was granted.

The plan is to come on air at about 6 UTC.

The antenna will be the 300m vertical kite antenna. I'll plan to serv= e the bands 33km and 46km, i.e. 8970 Hz and 6470 Hz. Since i made a new= tap on the TX coil i can now resonate the 300m antenna on 6470 Hz too. This should give a about 4 dB stronger signal on 46km.

Since the gap of low QRN is much smaller now, the experiment will not take m= any hours, maybe just 4 or 5.

Maybe i can get the 4 kVA generator and will produce a 6 dB stronger signal b= ut this is not clear so far. Otherwise i am limited to 550 W TX power. I will limit my antenna current to 2 A in order to prevent a HV breakdown on the co= il and due to thermal losses. At 2 A antenna current i should have up to 250 mW= ERP!

The program is to start a longer dash, about 40 minutes, GPS locked on 8970.00000 Hz, then a message in DFCW-600. Depending on the feedback of receiving stations i will try to send DFCW-60 or DFCW-10 or DFCW-3 and CW. Then i'll move to 6470 Hz, transmitting a 40 minutes dash and a "K" in DFCW-600 or so.

As usual the signals will be visible on my grabber in 40 km distance:
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.ht= ml for 8970 Hz and
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2= .html for 6470 Hz (spectrogram still not available)

but surely visible on many other grabbers too ( see https://sites.google.com/site/sub9khz/vlf-grabbers= for a list of available Dreamer Band grabbers).

Some new VLF receivers appeared since my last experiment. Two of them are: http://qsl.net/4x1rf/yo/vlfgrabber.htm&nbs= p; (1435 km)
http://www.ok2bvg.cz/vlfgrabber/    (598 km)
Leaving a trace on these and all other new and old VLF stations is the goal!= Despite high QRN and the longest days in the year (here in EU) i am optimist= ic.

Maybe Markus/DF6NM or Marco/DD7PC or someone else in DL wants to be availabl= e on the phone for QSP to the reflector?

Looking forward to the weekend and hope all works well and we'll have much a= ctivity.

Best 73, Stefan/DK7FC
