2Tone diff. MMTTY

Vytenis LY2KZ
 

Hello
For RTTY I use AFSK with 2Tone keying.
everything works fine except that when I am tuned to the signal, there is a difference between MMTTY signal and 2Tone. About 56Hz. Please see a picture. What might be wrong in my settings?

Looks like in 2 tone you have allowed the frequency to move to accomodate an incoming signal to be decoded, whilst it is fixed in mmtty
