please disregard the graph description, this is from 3h periods with 92.6uHz bins, i'm running a better resolution plot now, but it will take a while to calculate (only 1.6GHz cpu)

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
