My timing is off a bit too. I expected a 0.1 - 0.2 for
the propagaion delay of CHU and about the same for my reaction time,
but a whole second seems like a lot. It's time to get GPS or a clock
from the DOXCO.
Thanks for an interesting day on the long waves Markus, Paul and
Domenico!

Yes it seems to be loosing a few seconds - 22:00 and 22:30 decoded alright but
had to shift the timing (though I don't trust my timestamps too much any more).
start Eb/N0 time offset
UT dB seconds
2100 10.3 1.1
2130 nil
2200 7.2 3.5
2230 8.8 4.5

The timing is off by a few seconds: the 2200 sequence ended at 22:20:19.
I think the old antenna is several dB down and that isn't helping things.
Oh well, at least the message arrived! It was very much a joint effort.

transmission, only a couple of bogus decodes with very high rank numbers. The
signal is competely invisible now, and to make thnigs worse DCF39 has gone
into another hyperactive period, splattering all over the band. Will keep
trying...
