Schön ist, was gefällt.

Those are 3dB Lego bricks I hope.

I couldn't rx anything from 10:20 to 14:00, not a trace.

Is this a record distance for 5170 Hz? Probably is for
fixed antenna. I think Stefan's 8th kite experiment
(Oct 23rd 2010) did quite well. Jacek conveniently
summarises the results here

I don't think the 10th experiment went further at 5170.

Looks like the record was 904km, is now 1028.4km?

Has the frequency changed to 5170.0016 Hz? A new line
has appeared in a later spectrum.
