Ed, The SDR-IQ apparently uses the USB connection for both audio stream and rig control, but the KX3 does not. The I/Q output of the KX3 is baseband audio, which would need to be fed to a soundcard. The rig control is separate and will communicate with the KX3 through the RS-232 serial connection, so if you don't have a real serial port, you will need a USB to serial adapter to achieve that connection.
BTW - there seems to be nothing "universal" about the "Universal Serial Bus" - each device version seems to be different requiring its own driver. OTOH, the basic RS-232 port has always been "universal" - it just works because there are no "bells and whistles" (but that is getting a bit off-topic, thanks for listening to my rant). 73, Don W3FPR On 11/10/2011 5:28 PM, Edward R.
