Giving this "problem" some additional thought ...
WSJTX can not select "SPLIT" to transmit on VFO B in order to
automatically work a station heard on the Sub RX. However,
here is a starting point for the rest of the configuration ...
For the Main RX (VFO A):
Set Rig to Elecraft K3/K3S
Set Mode to Data/PKT (DATA_A)
Set Split Operation to either None or Fake It
(Fake it probably works best if you have a wide filter)
Use an interface that allows RTS or DTR on a dedicated
serial port for PTT
Audio (RX) USB Audio CODEC <LEFT>
Audio (TX) USB Audio CODEC <LEFT>
For the Sub RX (VFO B)
Set rig to *NONE*
Set Mode to *NONE*
Set Split Operation to *NONE*
Use a *Separate serial port* for PTT (DTR or RTS)
Audio (RX) USB Audio CODEC <RIGHT>
Audio (TX) USB Audio CODEC <LEFT>
Notes: Sub RX receive bandwidth will probably be limited
to 200-2600 Hz (depending on the widest filter
installed in the Sub Rx)
Since the VFO B transmit will be "fixed", TX
offsets will be limited to 300-2600 Hz. Try
to stay above 1,000 Hz.
You will need to manually activate "Split" (TX on
VFO B) to call a station copied on the second
instance of WSJTX.
*DISABLE* "Auto Seq" on *BOTH* instances. You do
not want one instance to "take off" on a new
QSO while working someone else.

Since WSJTX does not understand the concept of a second receiver there
is no way to provide CAT control for the Sub RX or transmit on VFO B
as if it were a separate rig.
However, you can start a second instance of WSJTX to receive on the
Sub RX - start WSJTX with the --rig command line argument (see the
WSJTX Users Manual sec. 16.5). You will probably also want to
specify a special configuration for the Sub RX that sets the RX
Soundcard to "USB Audio CODEC" <RIGHT> so it is listening to the
correct receiver. Specifying a start-up configuration is done with
the --config<configuration-name> command line switch (WSJTX Users Guide
sec 10.1.3)
As the developers of WSJTX are fond of saying - "Study the On-Line
Users Guide!"

Has anyone run two instances of WSJT on a single K3s with the SubRX so as
to be able to monitor both 50.323 and 50.313?
Of course I'll only be able to transmit on the instance that has the Main
RX but it would be handy to be able to see both.
Thanks
