The ability to manipulate the signals via software is a plus, and if it
is done in software, one could also integrate the software via Win4K3 /
com0com for CAT integration.... multiple ways to skin the "cat". <smile>

Dave,
My opinion is that there is no need for the SDRPlay, and you can have
better integration with the K3/P3.

Aha, NOW the proposed add on module makes sense to me... assuming one
already has a P3 (as I do), adding this will make the P3 appear as a
USB device to SDR software on a PC (much like a SDRPlay or RTL SDR
dongle. Correct?
What will be the advantages of this versus connecting a SDRPlay, etc
to the P3 IF Out?

Nice explanation, Don.
However, when we do an I/Q add-on for the P3, it will be fully
digital (like a USB sound card), not analog (like the KX3’s RX I/Q
outputs).
These digital signals already exist in the P3; we just need to
repackage them for use with a computer.
