[Elecraft] K2 and data modes

[Jerry]

OK,   I've been digging around in the archives trying to answer this question
and really haven't found the answer.

SO,   what is the best set-up for running digital with the K2.

I'm running Windows 7 64 bit on a new HP desktop with integrated RealTec 
soundcard.   Using HRD and DM780.........

I have not set-up an interface between the PC and the K2 just yet.

Just wondering what others are using and how you hooked that to the K2.

HRD handles rig control and PTT just fine but I have no output for Digital
modes.  When sending PSK, the rig will go into TX but no output power and 
no ALC defection.  

No surprise there since I'm not putting any audio back into the K2.

Anyway,  I assume the only way to feed audio into the K2 is via the mic jack???

OR  it there a mod I haven't heard about ??

thanks in advance for any info:
