[Elecraft] Digital mode advice

[Pawlak, Daniel L]

Hi,
                I have a K2 (ser no in the 3000s) and would like to set it up to operate with the digital modes. I followed the thread about getting started with JT65 software and will probably try that. My question: is there some guidance available to help me set up my K2 for digital modes. Many moons ago I hooked it up to my old PC and was able to receive digital transmissions, using one of the common programs at the time; but, I did not transmit. Is there an interface box I could buy or build (kit?) to get my on the air?
Thanks.
