I believe I am running 4.33 (what shows in CONFIG).

What we want for WSJT modes is full bw, totally flat freq.
response.  If I could get 13-KHz it would be great for JT-65 but it
appears the K3 DSP limits audio out to about 4-KHz except in AM or FM
modes (which are useless for soundcard programs).
---------------------
BTW no one has answered my question how to set DATA-A modes when
using the K3 Memory Editor.  I seem to get random settings when I
chose DATA-A with the Editor.  I want it to default to DATA-A USB for
use of most soundcard sw.

I can manually change this with DATA MD key but the change is not
saved and it reverts to whatever Memory Editor chose if I change
frequency by selecting memory channels.
