It will actually be significantly more than +/- 20 kHz. But the final  
spec is TBD.

The +/- 10 kHz limitation on dual watch is due to the DSP, not the  
QSD. (The new DSP in the KX3 has plenty of horsepower for all planned  
KX3 features, but it is not a fire-breathing monster. We have to keep  
receive current drain low.)
