[Elecraft] RX I/Q output planned or thought about for the K3/P3?

[Matt Zilmer]

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....
