Hi George,
You will find suitable settings on DF6NM's VLF grabber site:
http://www.mydarc.de/df6nm/vlf/vlfgrabber.htm
Scroll down to the bottom of the page, right-click the link, "save as",
and unzip. Then load the file from SL's "file" menu, or install it under
the 'quick settings' menu.
Cheers,
Wolf .

i will return back home about 5 pm
I TESTED SOME CONFIGURATION FILES FOR SPECTRUMLAB ...BUT I DONT THINK
I HAVE THE CORRECT FFT SETTINGS
CAN YOU PLEASE SEND ME A SETTINGS FILE SUITABLE FOR YOUR TRANSMISSION?????
PLEASE ANSWER!!!

*Subject:* VLF: DK7FCs 5th VLF experiment...
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
