First, there could be better result (Eb/N0) in another phase pattern. Second, the signal in this file is very strong and without significant QSB. Things could be much harder when coming to the limit. Also, as explained by Markus, the 100% is for 15 deg steps. Usually 30 deg steps are fine.

But someone could write a script that automatically feeds the decoder with the latest file. So things could be automatized. This is not yet done. Maybe someone will do it in the future, if requests become more and more :-) 73, Stefan > > Anyway thanks Stefan for the instructions. > > 73, Tony, EI8JK > > > On 15/10/2016 19:57, Markus Vester wrote: >> Hi Stan, >> >> filesize is 2.1 MB, a bit large for email.

Yes. But someone could write a script that automatically feeds the decoder with the latest file. So things could be automatized. This is not yet done. Maybe someone will do it in the future, if requests become more and more :-)
