You are strong visible at OE3GHB and Paul Nicholson. The QRN is pretty low this morning, just like yesterday. There seems to be a trace slightly above 8970.04 Hz on my grabber but i still haven't identified the "K".

There were some changes in the latest SL Version (V2.76b16 and above) on the noise blanker. I tried to find better settings to bring out a signal of the noise, without further success.
