Dear group,

I is a long time ago that i have done the last experiment. *Tomorrow*, 
the WX could be suitable and i have time and motivation to try the next 
experiment on *8,97 kHz*. But the WX is a little risky 
(http://www.windfinder.com/forecast/frankfurt) and so i do not yet know, 
if i really can come up. So it is just a uncertain announcement. Maybe 
Markus/DF6NM, if he has time, will inform you about the actual state.

In the last weeks, the QRM less window becomes smaller and more early. 
It is *arround 5...8 UTC* 
(http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html).
So, i plan to start transmissions at arround 7 UTC on 8970,0 Hz. I want 
to check the new 600W PA and the new additional earth rod. Antenna 
length is still 100m. The amperemeter will also be tested the first 
time. Modes will be DFCW-600 (50mHz shift) and a transmission in DFCW-60 
(500mHz shift) if i can reach my grabber in the DFCW-60 window in 37km 
distance. If the wind is stable and i have enough time i will do first 
receiving tests using the TX antenna! This is to prepare the first VLF 
QSO above 100km ;-)

So, let's hope for good and stable wind and no rain, dreaming...

Will anybody listen to the experiment except my and Markus' grabber? ;-)

73, Stefan/DK7FC
