The trick involved in that switch is a very high isolation between the two IF's (RXA and RXB) currently very nicely highly isolated. If that is degraded, then one starts hearing in one receiver the contents of the other. Not at all a trivial modification, as high isolation switches are not cheap. So I suspect dynamically selecting display on one RX or the other has a big price tag to it. And perhaps has an internal space price to it.
I would think, however, that when installing a sub-RX, that perhaps it could be cabled and the K3 options set to use the sub-RX on the P3 all the time, WITHOUT opening the pandora's box of high-isolation switching of RX IF's. This would be in the same vein as choosing the RX paths when installing the sub-RX to start with. Without the time to think that through carefully, I'd currently chose that were it available. 73, Guy.
