[Elecraft] K3 CW Rx Audio

[John Unger]

I'm still waiting for my K3, but...

I guess from the fact that you went through these gyrations means that one 
can't simply set the roofing filtering selection on "auto" and dial in a 
DSP width of 2700 Hz., e.g., or whatever with a K3 and have the 2700 Hz. 
SSB filter as the roofing filter; like I can with my Orion?

What am I missing?
