[Elecraft] K3S line out and sidetones

[Frank O'Donnell]

If the K3S is placed in TEST mode for the purpose of CW practice without 
transmitting, is the CW audio available on the rear panel's Line Out 
jack? Or can it be sent there via a menu setting?

For the purpose of a Zoom meeting, I'd like to send CW practice audio to 
an external USB audio interface that expects a line input. If that's not 
feasible using the K3S's Line Out port, I suppose it might be pulled 
from the headphone jack? If so, is there anything I should be looking at 
doing to adapt it to the audio interface's line input?

Thanks much,
