No. I mean USB, as in digital output, as is found on the USRP (for example).

I see no attraction in yet another analog step that is only going to add
noise and interference, complicate PTT and control signaling,  and leave me
with a mess of more cables and boxes in order to interconnect it.  (What
netbook has stereo inputs? what netbook has inputs that aren't full of
spurious tones from the computer?)

Conceivably the KX3 could be trickle charged (500ma at 5v) via a USB client
connection, meaning a complete computer-enabled mobile station could be
[antenna]-[kx3]-[netbook]-[power] which would be clean indeed.

Exactly.
