Hi Stefan.
Either day is fine for me, although Saturday is AC mains free for me
... and what a difference that made on Wednesday. I could see
stations I had never seen before including the "staircase" waveform
that others have reported as well as a frequency hopping
transmission.
I will just have to go /P and get away from power lines.
Good luck.
Tony, EI8JK.

Dear VLF,
This weekend i plan to do my next kite experiment. 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
quite 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 transmission 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 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 short 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
transmit 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
test 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
possibly on the phone to make QSP to the reflector, just like
Markus
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
(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
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 both is possible
here. I would prefer sunday, if the rain forecast changes to sunny
:-)
73 and looking forward to the weekend :-)
