Jer, It all depends on how you have your K3S physically configured.
If you do not have the subRX installed, that is not possible - although you can connect whatever antenna you now have on ANT2 to the RX ANT input and select the RX antenna.
If you do have the sub-receiver, then you can use the ANT2 for receive on the subRX by selecting the AUX input. Take a look at the antenna routing Figure 4 on page 45 of the K3S manual. As indicated, the subRX AUX antenna input can be connected to either the KAT3 (solid line) or to the BNC AUX RF jack (dotted line). Which one is actually connected to your subRX AUX input is a decision that is made at the time you built the K3S and added the KRX3. Factory built K3S are normally connected to the BNC jack, but you can add the cable to connect it to the KAT3.
If you connected the AUX input on the sub to the TMP jack on the KAT3, then when you select the AUX antenna, the sub will be connected to the non-transmit antenna. In other words, if the main is using ANT1, the sub will listen to ANT2. If you switch the main to ANT2, the sub will listen to ANT1.

Hi, I've read the owners manual and Fred Cady's K3 manual. Playing with the rig and still can't figure this out. Desired end result: When working split I want to receive on Ant2 and transmit on Ant1. I have the ATU option installed.
