I've just built K2 #5957 and installed the DSP unit. Radio and DSP are
both impressive as is. It seem "intuitive" to me that the DSP filter's
center frequencies should agree with the CW sidetone. That is, if I use
a 440cps side tone, then all the DSP center frequencies - on CW - should
be centered on 440cps, also. Am I think correctly on this point?
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.
