Hi Markus,

I see you're displaying a 7th Schumann resonance on the DL0AO grabber site.
Edgar pointed me to the idea to enable "show radio station list" in SpecLab, which is now done. I added just 6 markers, although a 7th trace is actually visible here as well, with poor SNR though. This leads me to the question if a noise blanker with high peak/average (blanking only strong local bursrs) threshold could be useful to improve the Schumann SNR. Do you have a NB enabled there?
73, Stefan
