The path to JA is (was) not open today, see the DCF plot at 
http://icas.to/argo/eu.htm
Yesterday the QRN was way lower and the signal levels about the same, 
i.e. the SNR was much better. And i was active to that time of the 
highest DCF S/N. Anyway no trace at JA8SCD. It's more than twice the 
distance to JA, compared to UA0AET.

It's interesting that good decode levels, or clear spectrograms, can be 
seen at UA0SNV. As you say, that distance over land is quite a challenge.

But be sure, it is more likely to leave a trace to the right time and 
right frequency than making a OP32 decode. That applies for the path to 
DU1GM too, of course.
