Hi Domenico,

OK. Many things need to be improved on this idea. Your suggestions are welcome !
Some more ideas: You could further modify the data given out by the decoder.
For example, instead of

-----------------------------------------
2017-07-05_08:59:30   start time + 30 s  on 137.495 kHz
found rank 2905 ber 3.5786e-01 Eb/N0 -1.1 M -2.327269478e+02 [64+!.KLFH4J50&,] 
ps [ 83  -90  -60  -90  -60]
2017-07-05_08:59:30   start time + 30 s on 137.490 kHz
found rank 0 ber 9.9798e-02 Eb/N0 9.8 M -9.171875610e+02 [GM ALL IW4DXW K] ps [ 
 1  180  180  180  180]

i would write:

-----------------------------------------
2017-07-05_09:00 UTC on 137.495 kHz : Rank  2905 | BER 35.8 % | Eb/N0 -1.1 | 
message: 64+!.KLFH4J50&, | phase [-90  -60  -90  -60]
2017-07-05_09:00 UTC on 137.490 kHz : Rank     0 | BER 10.0 % | Eb/N0  9.8 | 
message: GM ALL IW4DXW K | phase [180  180  180  180]


...into a single line. This looks much more structured on the screen.

And what about running the decoder each 30 minutes? :-) If the transmission takes 16:32 mm:ss, then there is quite some time to complete the decode process.
