[Elecraft] K3 receiver desensing on CW during contest

I'm at work and don't have time to check any of this ... But I was under
the impression that it was not this way.  Signals outside of the DSP
passband but inside the roofing filter passband would activate the DSP.
So, with a 2 KHz roofing filter and a 200 Hz DSP, you'd have very few
signals being heard by the OP but lots of signals affecting the AGC.

Is this correct?
If a cw signal falls within the DSP passband it should and will pump the
AGC. If a CW signal falls outside the DSP passband it should not pump
the DSP's AGC. Steve Ellington
