Rich;

Since you are talking about the K3, I believe your conclusion to be correct, 
but I would not (yet) rule it out. I don’t believe that the K3 outputs the 
RxAnt status on the Auxbus. Interestingly, the K2 _does_ output the Rxant 
status, and the KRC2 can respond to that inout, although it may require a bit 
of extra work on my part.

I will do some additional research on the code (it has been quite a while…) and 
let you know if what you want is doable with the K3.
