Unlike the K2, the sidetone pitch and filter center frequency are 
adjusted together, with one knob. There's nothing to realign.

You can press SPOT and hear the sidetone as in the K2, you can use the 
manual CW tuning feature in which you center a little dot on the 
display, or you can use the automatic CW tuning feature in which you 
press SPOT and it tunes the signal in for you!

The CW tuning indicator also works for RTTY and PSK -- I don't know if 
the automatic tuning does, and I'm not near my radio to try it; but 
someone else will chime in.
