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
