Hello LF,

Many thanks for reports from Victor, Henny,= Jim and Jean-Pierre so far.

I had Stefan on the phone 5min. ago and pas= sed to him this information.

Stefan told me the weather is perfect with= very stabile wind conditions. He has around 900mA antenna current and 550W Pout.<= /span>

 

Please note DK7FC will stop shortly the car= rier (which was on for abt. 1h) and switch to DFCW600. He will transmit 2 characters and afte= r this transmission he will change the QRG to 6470Hz.

Dear VLF,

This weekend i plan to do my next kite experiment. I have got the permissi= on for a kite ascent up to 300m above GND on my QTH in JN49IS36VH.

I will be QRV either on saturday or on sunday, depending on the wx. Attached you see the current wind forecast. For saturday the wind is not optimal, a little weak but it will be dry. On sunday the wind is quite str= ong and stable but there is probably some rain... I will have to see on friday evening if i can start on saturday or sunday and will announce that here.<= br>
If i will start on sunday, where the SAQ transmission takes place, this wi= ll be no problem since one can listen to SAQ and receive my transmission on an= other computer based RX (e.g. SpecLab), so both can be done to the same time :-)= .

The starting time should be as early as possible. I have the permission at 6...16 UTC!

The program is to...

- rise the 200m vertical and transmit a long carrier (30 min) on 8970 Hz,= after that a message in DFCW-600 and after that a message in DFCW-120, then a sh= ort CW test.
- transmit on 6470 Hz in DFCW-600 hoping to be copied at further stations (maybe M0BMU, SQ5BPF, OE3GHB, PA3FWM...?)
- if the wind will be optimal i will add another 100m and will try to tran= smit at 5170 Hz, 58 km band. This might be once again the lowest frequency an amateur has ever transmitted and reached the far field and above 1 Lambda,= so each reception will be a WR for amateurs ;-) BTW, my grabber in Heidelberg= is in < 1 Lambda ;-) The mode will be DFCW-600 as well.
- Then, coming back to 8970 Hz (maybe in the late afternoon) and transmit= a looong carrier for long time integrations, maybe for a new ODX.
- reach 1,4 A at 8970 Hz, 1 A at 6470 and 5170 Hz
- be detected at 3 new stations and a new ODX ;-)
- use a GPS disciplined transmitter (trying SpecLab as the VFO and DFCW generator the first time)
- measure the R, 'C' of this 300m vertical on 137 kHz, preparing a new tes= t there ;-) Since it is 55 % of a full size lambda/4 GP, 5 pF/m is not valid= i assume
- be fascinated by the view of such an antenna which easily finds place in= my car after the test ;-)

Until now i don't know who of the german LF group members would be possibl= y on the phone to make QSP to the reflector, just like Markus did it in the pas= t. If there is a german member who likes to do that job, please send me a person= al mail to exchange the phone numbers (Festnetz oder O2). Otherwise i have to= play my game there alone and will see what happend in the evening ;-)

BTW, the generator is running again. It started to run again just as i hav= e packed all my stuff in the car after the last experiment :-/ Never mind...=

Have i forgotten something?

Please tell me if you think it is no good idea to transmit during the SAQ transmission or what is your favorite day, if both is possible here. I wou= ld prefer sunday, if the rain forecast changes to sunny :-)

73 and looking forward to the weekend :-)

Stefan/DK7FC
