[Elecraft] Receiving with Skimmer SDR on K-3 transmit antennas

I would like to be able to connect my SDR (an RP-16) to my transmitting 
antennas, and have it automatically muted when my K3/KPA-1500 goes to 
transmit.  The idea is to have the best possible antennas available for 
Skimming while active in contests.

It seems to me that I should be able to connect a splitter between the 
RX Out and RX In ports on the K3, and use that to feed the SDR by 
pressing the RX Ant button  (at a cost of ~3.5 dB loss, of course).  
Question is, what happens when I go to transmit - is the RX Out line 
muted so that my SDR won't try to spot me? Ideally, I'd think it would 
be, but I've groped around in the K3 manual and Fred Cady's book, and 
haven't found a concrete answer - can anyone help?
