Hi Paul,

Very nice, thanks for generating that decode at SQ5BPF. Almost half the 
distance to Alex. The 12th transmission is running now and i am happy to 
be able to see the PSK again on the grabber.
If you can get the data from all transmissions, i hope there is only one 
message shown (no additional false decodes) at rank 0.
73, Stefan
