[Elecraft] Elecraft K3 with K2 as station panadapter setup?

[Sam Morgan]

I want to use both my K3 and my K2
at the same time, on the same frequency and antenna.
I wish to TX and RX on the K3.
I also wish to use my K2,
which has a softrock being use with PowerSDR/IF as a panadapter,
as just that, a panadapter on the same frequency using the same antenna.

I'm sure this is a relatively simple thing to do,
but my aging gray matter just switches to the
'you want to do wat?' mode
and I end up in an endless loop of
how to connect all this
and not hurt any of the equipment involved.

All physical connections are with serial cables to a desktop rig.
I have both HRD 5.0 and DXLabs, but prefer using HRD.
I use PowerSDR/IF for the panadapter display.

I have heard of some virtual serial ports or bridges,
but am clueless as to what, which, or how to involve it/them.

TIA
