[Elecraft] Newbie question re digital modes

[Bob McGraw - K4TAX]

I suggest connecting the radio to the computer via the single USB 
cable.  It handles the audio and the radio commands for CAT control.  
The SignaLink USB is not needed nor preferred in this case.  Configure 
the FLDIGI application through the various menus in the software for the 
radio using the HAMLIB menu in the application.

Yep, assuredly he receiver audio was being heard by the mike in the 
computer.
