[Elecraft] Changing CW pitch?

[Cameron Francey]

And if I'm not mistaken if you also have the audio filter add-on connected you need to adjust that to the new center frequency too.

I actually recently just done the same task on my K2.

Cameron,

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.
