[Elecraft] RTTY on the K3S

[KE1B]

Is there any way for the K3S to take its audio from the USB codec rather than the Line-in or Mic-in? I don’t see that choice in the menu.

Conversely, is there any way for N1MM+/MMTTY to send ASCII data to the K3S for FSK transmission. I don’t think they are set up to do that. What I am trying to get is a one-cable (USB) solution for all modes. (CW works fine with RTS/DTR over USB.)
