The simplest solution, which may also be the best, it to connect the sound 
card in your computer to the K2, and use the KIO2 and the CAT command for 
PTT.  I have done this.  I connect the mike input of the K2 to the Line out 
of the sound card through an attenuator consisting of a 10K series resistor 
and a 1K resistor to ground from the K2 side of the 10 K resistor.  I use 
the phone jack for audio out of the K2, and use the same attenuator for the 
input to the computer sound card mike connection.  I also use an isolation 
transformer on both the input and output sides to reduce hum caused by 
ground loops.  You also need a PSK31 program.  Hamscope, MixW and Zakanaka 
all are good programs that have CAT capabilities.  The CAT interface will 
also allow for band selection, frequency control and readout, mode 
selection and filter selection in the K2 as well as some neat combinations 
of these.

You can also buy a commercial interface and use nearly any PSK31 program as 
you are not using the CAT interface.

I can give you more details off reflector.
