[Elecraft] K3 and data modes

[Ken Chandler]

Hi group
Question
Knowing that the k3 will tx data psk, afsk etc, I'm a bit puzzled and  
I know someone here knows the answer, but my apologies if this has  
already been covered.
Working. PSK es AFSK data modes I have always used isolation  
transformers between the radio es computer to prevent ground loops etc.
If I direct wire line in, line out to the K3 &  computer what is there  
to prevent RFI ground loops etc.
Previously, I have used Isoterm devices from Johnny Melvin, G3LIV
Which are very good.
So do I need a seperate device between the k3 and computer or am I  
barking up the wrong tree es the k3 as a stand alone unit will do all  
that I want to do!!!!
