This is the one feature that I really wish the K2 had.  My TS-940 and 
756-ProIII both have this, and I find it very helpful.  It's not only 
nice to be able to customize the sidetone pitch, but I like to tweak it 
easily via a front-panel knob every so often during long operating 
periods, like contests - adjusting the sidetone (and zero-beat point) up 
or down a little from time to time seems to help minimize ear (or is it 
brain?) fatigue.
