Hi Markus, Paul, Eddie, Marco, Jim, Renato,

thanks for the positive feedback.

Yes, i will do it again on another frequency. Hopefully the QRN stays low for some time longer. Or i have to add more power! Hmmm, critical, maybe.

2970 is the strongest line.  At least 3 sigma, maybe 4,
depending on how you treat the lumpy floor.  A physicist
would insist on 5 sigma but the fact that the peak is
at exactly the right frequency is significant in itself.

I was doubtful looking at the spectrogram but having
plotted the pixels I am convinced.

Best I can get in Todmorden is 2 and a bit sigma
using just the daytime signal in 3.9 uHz.  Not
significant at all.  Would need at least another 7
days of transmission.
How does that peak look so far, in a spectrum? What happens if you put day and night together, maybe with some phase correction?
