The Behringer UMC202HD is available from stock from sources like Amazon, 
at least at this side of the pond. It has a low noise level, excellent 
dynamic range and can do 192kHz sampling.
It is supported by Win11 and MacOS.

It also has an "audio output" and headset output that can be used at the 
same time, independent with the two I/Q inputs.

Given that it is available (and the price has dropped, at least over 
here!) it would still be my prime choice. The disadvantage is that it 
has about the same size as the KX3 radio itself.

Some time ago, I got a Creative E-MU 0202 with the purchase of a LP-PAN 
box. The E-MU is not only out of production, it depends on a driver that 
I could not get working on Win11. For me it is a doorstop and I got an 
UMC202HD instead.

I would still recommend the Behringer today. It will not be available 
forever, but it is available today, it is supported by today's computers 
and works well. What is not to like?
