Hello,

DK7FC,=20 Stefan started to TX on 6.47KHz (you can check on http:/= /www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html)

Then=20 he will QSY to +/- 5170Hz. Stefan is not 100% sure about the frequency= .=20

Dear VLF,

Th= is weekend i=20 plan to do my next kite experiment. I have got the permission for a ki= te ascent=20 up to 300m above GND on my QTH in JN49IS36VH.

I will be QRV eit= her on=20 saturday or on sunday, depending on the wx. Attached you see th= e current=20 wind forecast. For saturday the wind is not optimal, a little weak but= it will=20 be dry. On sunday the wind is quite strong and stable but there is pro= bably some=20 rain... I will have to see on friday evening if i can start on saturda= y or=20 sunday and will announce that here.

If i will start on sunday,= where the=20 SAQ transmission takes place, this will be no problem since one can li= sten to=20 SAQ and receive my transmission on an other computer based RX (e.g. Sp= ecLab), so=20 both can be done to the same time :-).

The starting time should= be as=20 early as possible. I have the permission at 6...16 UTC!

The pro= gram is=20 to...

- rise the 200m vertical and transmit a long carrier (30= min) on=20 8970 Hz, after that a message in DFCW-600 and after that a message in= DFCW-120,=20 then a short CW test.
- transmit on 6470 Hz in DFCW-600 hoping to= be copied=20 at further stations (maybe M0BMU, SQ5BPF, OE3GHB, PA3FWM...?)
- if= the wind=20 will be optimal i will add another 100m and will try to transmit at 51= 70 Hz, 58=20 km band. This might be once again the lowest frequency an amateur has= ever=20 transmitted and reached the far field and above 1 Lambda, so each rece= ption will=20 be a WR for amateurs ;-) BTW, my grabber in Heidelberg is in < 1 La= mbda ;-)=20 The mode will be DFCW-600 as well.
- Then, coming back to 8970 Hz= (maybe in=20 the late afternoon) and transmit a looong carrier for long time integr= ations,=20 maybe for a new ODX.
- reach 1,4 A at 8970 Hz, 1 A at 6470 and 5170= Hz
-=20 be detected at 3 new stations and a new ODX ;-)
- use a GPS discipl= ined=20 transmitter (trying SpecLab as the VFO and DFCW generator the first ti= me)
-=20 measure the R, 'C' of this 300m vertical on 137 kHz, preparing a new= test there=20 ;-) Since it is 55 % of a full size lambda/4 GP, 5 pF/m is not valid= i=20 assume
- be fascinated by the view of such an antenna which easily= finds=20 place in my car after the test ;-)

Until now i don't know who= of the=20 german LF group members would be possibly on the phone to make QSP to= the=20 reflector, just like Markus did it in the past. If there is a german= member who=20 likes to do that job, please send me a personal mail to exchange the= phone=20 numbers (Festnetz oder O2). Otherwise i have to play my game there alo= ne and=20 will see what happend in the evening ;-)

BTW, the generator is= running=20 again. It started to run again just as i have packed all my stuff in= the car=20 after the last experiment :-/ Never mind...

Have i forgotten so= mething?=20

Please tell me if you think it is no good idea to transmit dur= ing the=20 SAQ transmission or what is your favorite day, if both is possible her= e. I would=20 prefer sunday, if the rain forecast changes to sunny :-)

73 an= d looking=20 forward to the weekend=20 :-)
