If you decide to use the KX3's I/Q output, be sure that the 2.5mm plug's 'shoulder' doesn't interfere with the top cover. There is a cutout for the RX I/Q jack but it's not designed for Radio Shack adapters (too wide). Some molded cables also have this problem.
HDSDR works fine with the KX3, using the I/Q output. You'll want to add some isolation though. The KX3 doesn't have its own isolation transformers because of mechanical design constraints. With the K3, isolation is built-in. FWIW, both radios are SDRs, their behavior being completely dictated by loadable software. Without software, both rigs are very robust hardware platforms, but a bit lacking in functionality.... 73, matt W6NIA KX3 #6 K3 #24 On Wed, 09 May 2012 08:01:05 -0500, you wrote: >Geoff; > >As far as I know, the K3 is NOT an SDR.
