I've used my KX3 with the Tiny Python Panadapter I
built per the April QST, using an iMic USB audio
card on the I/Q outputs, and it worked fine --
within the limits of the design and the Raspberry
Pi I used. Nowhere near as nice as the PX3 I'm
using now when I operate the KX3:-)

When I first got my LP-Pan and read the manual
(doesn't everyone do this?), I found it strange
that the audio outputs had the ability to lift
grounds (apparently to reduce noise/ground-loop
issues). I guess I must be doing something
right as I did not encounter any hum or noise
issues with audio shields grounded.
In the early years of building radio-computer
I/F boxes (HB) it became quickly evident that
isolation transformers solved a lot of these
"grounding issues".
I read your presentation, Jim, and gives me a
laundry list of things to check.
