[Elecraft] K3 Audio routing question

Hi Don,

Imagine a system with good isolation between antennae such as you can 
achieve with long yagi's at VHF/UHF. In my left ear I have the main RX 
with stations from the UK, in my right ear I have the sub RX and 
stations from Europe. I have a QRM from another G in my left ear when I 
am called by a weak station from Europe which I hear in my right ear. As 
the antennae have nice patterns I can barley hear the QRM from the G on 
the antenna pointing at Europe. Now I want to mute or attenuate the 
audio from the main RX and listen to the audio from the sub RX in both 
ears. I know this will not be diversity any more but I'd quite like the 
filter controls to continue to affect both receivers without having to 
press BSET. After I have worked the station I need to return to 
diversity mode listening to both receivers again.

Diversity mode almost does what I want with both receivers locked 
together, I just need to be able to select which audio I listen to at a 
given time. I can easily make up a box to switch the audio but I would 
have thought that what I want to do is not that uncommon.

Hope this makes more sense.
