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.
