Paul, maybe you can see a small peak at 8270.0050 Hz when putting this 30 minutes into one bin?

Stefan,
 
very good! You're braving the QRN again ;-) Your wideband and ELF screens are showing stunning tweek-resonance cutoffs.
 
I'm looking forward to see your signal here!

Betreff: LF: TXing on VLF again

Hi VLF,

Since a few minutes i'm transmitting a test signal on 8270.00500 Hz. It is visible in my DFCW-600 window on my remote grabber in 3.5 km distance to the antenna, http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html
The first RF power radiation here since years.
So far i'm not on resonance. The resonance was found at 8.67 kHz. Thus my antenna current is just about 30 mA in the moment. I'm continuing to work...

73, Stefan
