Sorry Uwe, nil here. All I can offer is "QR-" and "[email protected]=" at low SNR and high rank numbers.
 
I did see another carrier on 8270.000 this afternoon, presumably again from Roland DL3NDR.
 
Hey we need a band plan ;-) No we don't really. However I would suggest to move EbNaut activity away from the grabber waterhole by an integer multiple of the symbol rate (N*0.0333 Hz for 30 s, e.g. 8269.9667 Hz). Then any interference from carriers near 8270.000 will be suppressed by the sin(x)/x response of the EbNaut decoder's symbol integration filter.
 
73, Markus

Paul,
I counted on you!

Stefan, Markus,
did you decode something?

Uwe

That was enough, about 70% of the message was transmitted.

Copied an obvious correct decode with Eb/N0 = +2.4 dB.
