[Elecraft] K4 sound card capability

[Terry Brown]

I have a KX3 which connects to a signalink that connects to my computer for digital modes. 

I have not owned a K3(S).  I assume the K4 has an internal sound card to take the place of the signalink but I don’t know how it interfaces to my computer and it’s programs. Is the only thing needed a usb connection between the K4 and computer?

Hoping to see my K4 by year’s end.   I’m near the end of Group 1 and have no idea how many are in Group 1. 

Thanks!
