[Elecraft] K3S Quick Review

[Matt VK2RQ]

It is not just a matter of adding a soundcard for the I/Q feed, as unlike the KX3, the K3 doesn't produce I/Q signals outside the DSP. You'd need to add a quadrature mixer to the IF signal before the roofing filter to generate the I/Q signals for sampling by the soundcards. You could of course do this yourself outside the the radio by feeding the IF output of a KXV3A into a softrock/stereo soundcard, if you want. Or even more more simply, add a P3 :-)
