Hello Stefan, VLF,
Good luck there! I'll be looking for any trace of signal from you.
Fine! Your grabber is my hardest but realistic goal in this experiment.
:-)
When looking to your grabber (http://qsl.net/4x1rf/vlf/vlfgrabber.htm)
i see when DHO38 or JXN has a good SNR arround 10...11 UTC and arround
my sunset. So i will try to transmit on 8970 Hz to that time. Maybe i
find someone for QSP to the reflector again (Markus or Marco?)...
Any LF activity planned?
Yes. I will take the LF coil and the PA there as well. At least i will
find where i have to make a tap on the coil to resonate the 200m and
maybe even the 300m antenna. If this can easily be done i will transmit
in CW and DFCW-4 and DFCW-90 or so. The 300m antenna has about 50%
efficiency, so i need 1W TX power for about 1W ERP! ;-) My PA driver at
12 Vpp would probably enough to reach UK in DFCW-60 or so ;-) Will be
an exciting test! But there is a lot that can happen on that way. The
snow is just one of my worries but it works with some optimism ;-)

Dear VLF/LF group,
The wind forecast is still promising and so i announced my next VLF/LF
kite experiment at the german air traffic control and will get the
permission for a 300m vertical antenna during daytime. The WX is
promising on saturday and on sunday. Thus i will decide the day
tomorrow since the forecast becomes most probably as estimated 24 hours
before. My favorite day is saturday.
So, i will inform you tomorrow more detailed about the planned program.
Will someone try an attempt to receive that signal? :-)
73, Stefan/DK7FC
