Hi,
Direwolf's FIX_BITS isn't really a good option to decode better. It can, and
does, corrupt data by the nature of its design/principle
It's actually not a good option to use at all and it's better to set
FIX_BITS to 0 and only enable FX.25.

Hallo,
Direwolfs FIX_BITS ist nicht wirklich eine gute Option, um besser zu
dekodieren. Es kann, und
Daten aufgrund der Natur ihres Designs/Prinzips korrumpieren.
Es ist eigentlich keine gute Option, die man verwenden sollte, und es
ist besser,
FIX_BITS auf 0 zu setzen und nur FX.25 zu aktivieren.
