[Elecraft] K3: CW Sidetone on line out

[Ed K1EP]

When recording through the Line Out, I find that the CW sidetone is 
not present.  As far as I know, this was on the list of features to 
be implemented.  But has it been implemented?  The other day, I tried 
recording.  As I looked at the audio waveforms, I noticed that indeed 
the sidetone was present.  But, today, I tried recording again, same 
audio setup, and no sidetone.  The only difference is in settings 
that I may have unknowingly changed on the K3.  Was I imagining the 
first situation and there still is no sidetone available on Line 
Out?  Or is there and I just changed something on the radio?
