Regarding Observation 129626 …
I’ve vetted this as bad, because in the original spectrogram I can’t see any signal.
Today I’ve opened the audio file to have a deeper look onto the spectrum.
And there I found a signal:
Nearly all bad vetted observations of XIWANG-1 of the last weeks I have checked are good in fact.
Is it possible to shrink the dynamic range of the spectrograms?
The noise level of station 47 is never under -85dB and
maybe this won 15dB make the weak cw signal it a little bit more visible?
