In case you have wondered how to  connect Elecraft KX3  RXI/Q to PC audio card and configure PowerSDR  - here is a simple description with screenshots how to use KX3  as a software defined radio http://ag1le.blogspot.com/2012/12/simple-elecraft-kx3-and-powersdr.html.

I am running two instances of PowerSDR in parallel - one connected to Flex3000 and the other one to KX3.

I had few more hours to play with radios so I also found NaP3 software by Pete F5VNB.
It is based on earlier versions of PowerSDR/IF and PowerSDR* 2.1.4. 

NaP3 has integration with Elecraft KX3 CAT  - see instructions here:
  http://www.telepostinc.com/NaP3.html#Setup

Works well except I have some noise +/- 2.9 kHz around center frequency, probably coming from RX I/Q cable connected to PC soundcard.  Setting "Global IF Frequency Offset (Hz)" in  "IF Frequencies" tab  to 3500 Hz moves the noise so that I does not impact listening.   

If you have Elecraft KX3  and a Windows PC with audio card NaP3 is well worth trying out.  You get a free SDR   with 96 KHz wide panadapter / waterfall display  by investing 10 -20 minutes to configure it.
