==========
If I understand it correctly, the KX3 puts out I-Q audio that can go
directly into a sound card, and has an RS232 port that can go directly to a
CAT connection on a computer.
Some SDR hardware receivers or transceivers interface with SDR programs via
USB to control frequency. An example is the Softrock Ensemble, which uses a
Si570 chip to generate the local oscillator frequency. The Si570 is tuned
via a USB connection which in turn is linked to a program like Rocky by a
driver. The Softrock does not have CAT control, and Rocky will not send CAT
commands.
But for the KX3, none of this is relevant. No drivers are needed. It will
be exactly like hooking up LP-Pan, which just needs a sound card and a
serial connection.
