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

[David Gilbert]

I'm no expert by any stretch of the imagination, but it doesn't sound to 
me like that would be effective with any single rig, K4 or otherwise.

First off, as best I can tell you need to assign different rigs to the 
multiple instances of WSJT-X if run on the same computer.  I don't 
believe you can assign the same rig to two different instances unless 
you use two separate computers, and then you have the nasty problem of 
feuding CAT signals.  Please correct me if you have found that statement 
to be erroneous.

Secondly, you can't simultaneously transmit on both frequencies (unless 
you use Fox/Hound mode, which is an entirely different matter) and you 
can't receive on one frequency while transmitting on the other so you 
end up staggering your QSOs with no gain in effectiveness ... other than 
maybe quicker band switching than doing it manually.

It seems to me that to gain any benefit without using Fox/Hound you need 
two separate transmitters, of course fed through a passive combiner if 
using the same antenna.

Or what am I misunderstanding?
