Drew,
?HUH?
The "pitch" function that you say you want - change the pitch of a
received signal - already exists, just turn the VFO knob, it will change
the pitch of the signals which are being received. Normally one would
want to tune the desired signal to the pitch which matches the sidetone,
not the other way around. Just tap the SPOT button to zero-beat, in
fact the K3 can do that automatically (within a limited range).
Things that are changed by the PITCH control are the pitch of the
sidetone you listen to during transmission, the frequency offset used
for transmission and the CWT center frequency as well as the position of
the center of the CW passband - it does not change the pitch of signals
being received.
Can you be more specific about what you want.
