Hi Yas,
 
thanks for this grabber! In your split screen spectrogram, what is the difference between the upper and lower half?
 
Based on the visible Loran-C lines, your frequency calibration seems to be very accurate:
 GRI 9930: 137779.45619 Hz
 GRI 8930: 137777.15566 Hz
 GRI 9930: 137774.42095 Hz
 
Best 73,
Markus (DF6NM)

Hello Mike and all,

Thanks Mike for the info. 

Tonight, condx seems pretty good. DCF39 started to show up
about two hours before sunrise.

This is a temporal grabber and you need to manually refresh
every 5min. 

Sunrise here is around 20:00UTC.
