I will look for your signal on saturday and if yo= u will start on sunday the SAQ transmission wont last for hours. So it wil= l be possible to hear both - just with only one computer.
At the mome= nt I am testing my Mini Whip. I am not sure, if the S/N ratio is enough.= I will try to add a few meters to my four meters pole tomorrow. Possibly= the QRM will be to high here anyway.
Would it be a good idea that al= l RX-stations use the same setup (.usr) on SpecLab? I now have collected= 6 different files here in the reflector and I am a bit confused now which= will be the best to start with.

Betreff: VLF:= DK7FC's 8th VLF kite experiment

Dear VLF,

This weekend i plan to do my next kite experime= nt. I have got the permission 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 quit= e strong 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.

If i will start on sunday, where the SAQ transmiss= ion takes place, this will 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 shou= ld 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 short CW test.
- transmit= on 6470 Hz in DFCW-600 hoping to be copied at further stations (maybe M0B= MU, SQ5BPF, OE3GHB, PA3FWM...?)
- if the wind will be optimal i will= add another 100m and will try to transmit at 5170 Hz, 58 km band. This mi= ght 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 ;-) Th= e mode will be DFCW-600 as well.
- Then, coming back to 8970 Hz (may= be in the late afternoon) and transmit a looong carrier for long time inte= grations, 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 vertica= l on 137 kHz, preparing a new test there ;-) Since it is 55 % of a full si= ze 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 possibly on the phone to make QSP to the reflector, just like Ma= rkus did it in the past. If there is a german member who likes to do that= job, please send me a personal mail to exchange the phone numbers (Festne= tz oder O2). Otherwise i have to play my game there alone and will see wha= t happend in the evening ;-)

BTW, the generator is running aga= in. It started to run again just as i have 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 bot= h is possible here. I would prefer sunday, if the rain forecast changes to= sunny :-)

73 and looking forward to the weekend :-)
Stefan/DK7FC
