Thanks Stefan, glad to see that! Using EbNaut, 15 dB SNR in 0.63 mHz noise bandwidth should support about 12 characters per hour. But this will probably have to wait until you have finished your local self-test (unless I'd try to sneak into a gap between two CW dots ;-)

Useful traces appeared also in Todmorden and Breclav. With currently low QRN levels, Lubos' grabber might perhaps benefit from a little more brightness.

The carrier is off since 7:28.

Best 73,

Hi Markus,

I can see you very well in 424 uHz at up to 15 dB SNR.

Since 21:40 UT I am radiating a GPS-synchroneous carrier on 8270.0025 Hz, hoping for a trace on Stefan's grabber between the DJ8WX and local DK7FC lines. Antenna current is now 0.28 A with a bit of snow on the wire, should be around10 uW ERP. Hope to leave it on for a few hours.
