Thanks Fred. So If I follow you, I have to pick one of those two options?
I ask as in the installation manual, it states if you do NOT want an AUX input to the KRX3, you can skip the steps. As presented, I did indeed skip those steps but when I arrived at the menu, I thought to myself, “Well, I selected neither option, so which one do I choose”. It sounds like maybe I wanted BNC as I really just want to let the subRX share the main antenna. Thanks, Tom Schaefer 727-437-2771 P.S. Drowning in email?
