Since 11:46 UT I'm transmitting a carrier on 5170.0025 Hz, antenna current 0.21 A into approx. 8 m effective height. It looks like nice peaks are building up on the grabbers in Heidelberg and Amberg.

Markus, Maybe it is another effect that no one has observed until now: At night, the distance between Heidelberg and Nürnberg seems to be shorter, about 0.5 lambda on 5170 Hz. Genial! :-) 73, Stefan

...oh, indeed. I thought you already stopped transmitting but now i see on the DL0AO grabber that you are still on the air! Quite a difference between 12 and 16 UTC, 8...10 dB i estimate. I'm now sta

Yes the signal level change was quite drastic. During the early afternoon, some trace was just visible in your 3.8 mHz instance. Now there is even a small sharp peak in Cumiana. Unfortunately at DL0A

Yesterday the carrier was on until 20:30 UT, but completely invisible in Heidelberg during the evening. This morning I transmitted a couple of hours more (08:23 to 10:30, 0.19 A), leaving a a nice tr
