Like many others on this list, I feed the IF output from that into an external SDR (I'm using LP-Pan, but I also have tried a Flex 1500 and a Softrock). Of course, that too requires a sound card after the down-conversion done by the SDR. Those of us who have been using this setup are excited about getting direct I-Q output from the receiver. There's zero to be gained by having an outboard SDR box that would duplicate the down-conversion circuits in the KX3. My bet is that Elecraft would do a better job with that circuitry than today's SDR makers. And the output of that goes to a sound card anyway, whether it's inside your SDR or in a separate box or in your computer. The sound-card circuitry inside today's commercially available SDRs is nothing special and in many cases is no better than what's already inside your computer.
