[Elecraft] K3 Rtty Tx Setup Question

[David Wilburn]

I have K3 766 setup and trying to do RTTY AFSK.  Copied from a 
previous post;

1.  Connect speaker out from sound card to line in on the rear panel 
of K3.
2. Connect line in on sound card to line out on the rear panel of K3.
3.  Go to main menu, use vfo b to select mic select and vfo a to 
select Line In
4.   Turn on Vox by holding the Vox button.
5. Go to Main menu, select Vox using VFOB and pick a value for Vox 
gain. I have it set at 15 or so.
6. Use Mic to set line gain appropriately.  Mine is at 15 or so.
7. With mode Data, press DATA MD and select AFSK A

I have done all of these, but I cannot get the line in to go into 
transmit using VOX.  If I move the connection from the computer over 
to the mic in, and change the mic in config to rear panel, it 
transmits fin.  I am trying to understand why line out will not transmit?

My FP is in need of the mod, but I have not performed that yet.  I am 
doing all of this from the rear.
