[Elecraft] AFSK on K3

[Ed K1EP]

Bob-
Make sure you have the latest firmware.  Up until the recent release 
there were problems with the Line In.  One problem was that although 
you had Line In selected, it really wasn't selected unless you went 
in to the menu and selected another input and the re-selected Line 
In.  I would try that to see if that is the problem.  I had that 
problem when using basic LSB or USB modes with Line In.
