There is something I remember from the old radios and some really "bad"
headsets that were peaky in their response, and that was a moderate rolloff
above and below that allowed one to hear up there and down there but did
not allow it to dominate. I've asked for a config menu adjustment on the
APF but that never had enough support from others to move it up on the K3
do list.

The audio shaping could do that, but I can't put in a menu selection of
favorite settings, there is only the one. It would need to be easily
accessible for switching in/out on a QSO by QSO basis.
