Thread-topic: LF: To all VLF transmitters
Thank you Stefan

I'm QRV. But it's quite noise here during the weekend :(
Let's see if there is any trace in the spectrogram

>>I intend to run it for > 24 hours so tomorrow it is the time for you to watch your spectrogram(s).

I'll be watching every two hours :-)))

PS: AMAZING signal plots by Paul, as usual. Congratulations !

Hi Luis, Mike, VLF,

A carrier is now running since 21 UTC on 8270.005 Hz. I decided to use the large coil, so i can run more antenna current. The antenna current is now 600 mA, a 6 dB stronger signal than planned.

I intend to run it for > 24 hours so tomorrow it is the time for you to watch your spectrogram(s).

73, Stefan

PS: Luis, it would be a first detection of VLF in Spain!

Will be interesting to have a signal in the 36km band, Stefan
 
I'm also running my grabber at 8270.007 with SpectrumLab and 1pps sync
The 11904 Alpha is also monitored. Unfortunately still much noise in the VLF band
but let's try the 47uHz FFT
 
BTW. Signal stopped last night
