[Elecraft] K2 Filter Question

[Curt]

Thanks Don,

If the center frequencies were off, what would be the behavior tuning 
through a CW signal?  As I tune through a signal, the highest strength 
happens about halfway through the respective width, at an audible frequency 
that beats with the sidetone frequency in "spot".  I would think if the 
center were off, then the maximum would happen somewhere away from the 
center frequency.
