Ed, The short answer is YES.
You can change the sidetone pitch, but that is only the sidetone that you hear - and that setting also determines the transmit offset.
Assuming your CW filters are currently centered at your 580Hz pitch, you will need to move the center of the CW filters to whatever pitch you choose for the sidetone. That is done with the CAL FIL procedure. You will need the internal counter probe. It is easy if you use an audio spectrum analyzer like Spectrogram and feed the K2 ANT input with a broadband noise generator - you can see the peak of the filter passband.

I'm thinking of changing the CW pitch on my K2 from 580hz to 650hz, maybe 700hz........my question, do I really need to realign the filters? This is what I've read! I'm discovering I like a higher tone rather than lower CW tone. At 67-years-old, go figure
