[Elecraft] K4 Use Case Question - Support for multiple instances of WSJT-X

[Logan R Zintsmaster]

Here is a use case question.. 

The radio is connected to a single antenna.

VFO A is tuned to 14.074 MHz and VFO B is tuned to 14.080.  

An audio data stream from the VFO A frequency is "connected" to an instance
of WSJT-X decoding FT8. 

A second, independent audio stream from the VFO B frequency is concurrently
"connected" to a second instance of WSJT-X decoding FT4.  

Both instances of WSJT-X decode their respective audio streams,
concurrently.

Starting a QSO in either instance of WSJT-X switches the transmitter to the
appropriate VFO for the duration of the QSO.

The audio stream for the instance of WSJT-X not in the QSO is interrupted
while the transmitter is operating.

 

Can a K4 support this use case or is a K4D required?

Can this use case be supported if each instance of WSJT-X is in a different
band?
