Yes, John, both the variable filters and the DSP filters may be
adjusted for center frequency. However, while we older folk may lose
our abilities to hear, say, above 4000 Hz, there is not likely to be
a significant loss differential in the range for typical side tones,
say 550-1000 Hz. This is, after all, roughly in the octave range of
C'-C'' on the piano, and isn't really all that high.

Hi,
I have an odd question for the group.
As hams age, we begin to notice that our hearing decreases in
sensitivity in the higher registers.
In a K2, one can easily change the Spot audio frequency downward to
accommodate this process.
Is it straightforward to adjust the filters so their center
frequencies are lower, too?
Or am I way off the charts on this one?
