KDSP2 filter center frequencies

[RobertG]

Hello, all...

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.

Along these lines, is there a way to set the DSP back to factory
defaults? Pull the battery? I seem to remember reading in the manual
there was, but now that I want that info, I can't find it :|

You have to enter them.  There is a chart in the manual with the default
settings listed.
