It depends on how you prefer to operate.  If you want the received 
station's pitch to match your sidetone, then the answer is yes.  Some 
folks prefer the pitches to be different to make it easier to 
distinguish what's going on, especially when using QSK, in which case 
you would set the DSP filters to your preferred receive pitch.
