It is fundamentally essential to use very high isolation headphones to achieve K3NA's dynamic range goal (i.e., to hear the weakest and strongest signals with AGC OFF without kicking in the limiter).  It IS achievable.  It's not a matter of sensitivity.

There is no way, despite K3NA's excellent attempt

to set the K3's RF and AF gain controls to accommodate the
dynamic range of signals encountered on the bands, without riding
the RF and/or AF gain controls.  Maybe it is possible with
super-sensitive headphones, but not with any that I have tried.
