Bret, You have to switch the sub-receiver from the main antenna to the aux antenna. To do that go to BSET and press the ANT button. That will show which antenna the sub is on. It should say MAIN. Press ANT again and it should say AUX. Press BSET again to return to the VFO A display.

I might switch the SubRx to the KAT3A some day, as both antennas are TX, but am trying to set up for Diversity Rx now and having problems. I have two TX antennas - a 102ft G5RV ~40ft up N-S and a 43ft Vertical ~75ft away, both with remote ATUs at base. With G5RV on ANT1 and 43Vert on ANT2, all works fine. For Diversity RX, since the SubRX connects the AUX RX-bnc, I've tried moving the 43Vert over to the AUX RF IN bnc jack. CONFIG KRX3 is set to Ant=bnc. I'm not quite sure which buttons to select to get Diversity mode working. With ANT set to ANT1, I select DIV (long-press SUB) and see SUB on display between VFOA & VFOB and decimal blinking, but hear only in my left ear. What might I be missing?
