5th VLF experiment...
hi stefan
iam thinking to setup the loop and receiver
tomorrow moring on the roof and leave it unattended to grab.... and
leave
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
