[Elecraft] K3 Phones / Diversity Question

[Jim Bennett]

I just recently added the sub receiver to my K3. I've been using the Sub receiver (without diversity turned on) and all was fine. I have the Yamaha CM500 headset - one cable plugged into the Phones jack and the other going to the Mic jack. I also have an Icom SP-20 external speaker, and it's connected to the Spkrs jack. 

Well, I engaged Diversity mode and at first thought it was working properly. But, when I turned the AF to zero on the Main receiver, I realized that the audio on the Sub was almost nonexistent signals are there, but really, really weak. OK, so looking at the Config parameters, I noticed in the KRX3 manual that SPKRS should be set to 1. Mine was set to 2. I changed it to one and now have zero audio coming from the Sub receiver. Not exactly what I was hoping for.

What do I need to do to get my headphone audio in Diversity mode to act as it does with the Sub turned on, but Diversity off? 

Confused, I am.
