Hi Luis,

thanks for trying!

Eventually 42 uHz is to narrow. You could try a twice as high bandwidth, i.e. a half as long FFT window time and twice the scroll rate.

Hi Stefan, 17.47KHz

Sorry. Too much QRM during the summer here due to Air condition, etc  :(
Set and spectrogram which is not yet in the grabber. Updated every 15min

QRV again after long time out of QTH in vacations

Thanks Paul.

That would be good for the traditional QRSS-60 over our distance. Not bad at 
all for such a noisy summer!

Reports welcome :-)
A great signal in Todmorden, 881km.

About 22dB S/N in 278uHz, about -14dB in 1Hz.
