[Elecraft] [KX3] USB sound card functionality in the future?

[Dave Hartzell]

Interesting...  Not knowing much about the architecture, isn't most of the
hardware already on board to send samples out the USB?

Looking at the KX3 block diagram [1], I'm curious why you couldn't move
digital I/Q samples from the DSP to the PIC, then in/out to the USB port.

While I'm sure the existing I/Q port would work for me, its always nice to
be lazy and use one cable.  :)
