...4 transmissions completed. Unfortunately last night the transmission was aborted at 03:40 UTC due to an incorrect setting of the safety limit. So this transmission is of limited use.

It would be interesting to know the Eb/N0 of the sum of these 4 days to get an up to date impression how far i am away from a decode.

... 3 transmissions are completed now. Is there a decode? Or how much is missing? Any infos about the daily phase and Eb/N0, Paul?
Fortunately the DL0AO grabber is back. Thanks to the crew!
On the 424 uHz RDF plot i observed a phase inversion or at least variation! Is this propagation or happening on my side? Paul, maybe you could check the daily phase on your RX? Sorry, quite some queries. I hope you don't mind :-)
