This is close. As others have stated, two adapters are required. One is the 
Signalink (or other audio interface). The second is a serial adapter, 
preferably based on an FTDI chip. I believe it is the second you are really 
asking about. The serial adapter provides the actual control communications 
between the computer and the K3. It is the same interface you would have used 
for updating K3 firmware or otherwise controlling the K3 from the computer.

The Signalink should do a good job providing the sound interface needed for FT8 
with the K3. There are other less expensive solutions (and several that cost 
more as well), but since you already have the Signalink, use it!

WSJTX is relatively easy to get going, but you will want to read the manual to 
be able to understand and set the various details in the program. Just select 
the audio interface and the serial port in the WSJTX settings dialog and things 
should start working quickly. After you start playing, you will have more 
questions.
