Don,

Not trying to be argumentative, but...

The SDR-IQ uses a USB-2.0 interface and not audio.  Some SDR actually 
provide A/D conversion inside the box with digital output 
streams.  The units you mentioned are audio-baseband.

The only issue would whether one needed a good soundcard or not.

I understand that many sw provide for radio control so need that 
access (whether via USB or RS232).  K3 being one of those that offer 
external control.  I wonder if the KX3 will have that ability, as well?

Very handy for the "click frequency" operations on sw like psk-31 
(variants).  The eme SDR sw (Linrad) that I am using has this ability 
(if proper drivers are available for the radio).

Ed,

The I/Q outputs are baseband audio - just as would be the case with the
output of LP-Pan, or a Sofrrock receiver, or most any SDR receiver.  The
serial (or USB) port is only used when rig control is introduced in
addition to the panadapter function.
