That's the method for aligning the K2 filters recommended by Don,
W3FPR. It works great for the K2, I don't see why it wouldn't work for
a K3 also. That's a cool pair of calls too!

Folks,
some K3 filters have an offset with respect to the IF central
frequency that the firmware on the rig can compensate. Sometimes the
"offset labels" are gone and poking a zero offset on the configuration
is the only option.
I guess that feeding noise into the antenna and using an audio
spectrum analyzer may help to visually see the filter response, and
check if that "bell" is centered or shifted.
Am I right? Or is there a better method?
Inquiring minds wanna know.
