I really wonder about ab ab audio in diversity. That is both rx audio
in both ears. The "diversity" comes from the antenna. What does the
brain do worse in "diversity" with this ab ab mode of receiving?
Since you can't do it with the current K3 software, where is the A/B
testing shows the superiority of listening to separate signals in each
ear. I suppose there are papers out there on this.
Unlike many, in split mode I listen to both RX in both ears. No
problem. Adjustment of audio gain optimizes this situation on a per
station basis.

Respectfully,
This is not an issue of definition. I'm sure everyone agrees that
on-purpose listening to A-A is not diversity. What they are talking about
is a situational coping mechanism when using diversity as the main
listening mode in a contest.
This occurs in diversity mode when one ear has a very weak desired signal
and the other a very loud undesired signal. My current coping mechanism for
this is to push one headphone bell forward off my ear. It would be better
to temporarily switch to both ears on desired signal, but this is *very*
clumsy using the front panel.
A discussion on how to deal with it would be helpful. Using diversity in
contesting is a newly emerging skill that is only really emerging with
common usage of two receiver K3's.
There needs to be a non-dismissive serious response to these concerns. If
there are hard technical reasons why this should be done external to the K3
it would be good to known these and move on to an external solution. It
does seem though like the straightforward treatment is somewhere inside the
K3 digital number soup.

Arie,
The K3 may be in diversity, but you will only hear in diversity mode when
the audio is A-b.
The diversity effect is 'in your head' as your ears naturally pick up the
differences between the two receivers and your brain figures out which is
the best to hear.
When you have the audio set to A-A or b-b, you are hearing the audio from
only one receiver, and by definition, that is not diversity reception.

Don,
to set things up, I use a macro programmed in the F12-key in N1MM to copy
the freq/mode/BW From A to B, switch on the SubRx, set audio to A-b
listening and Link the VFO's. Switching of the audio is done in F9-F10-11
to A-b, A-A, or b-b respectively.
Of course I would like that I could switch the audio when the K3 is in
diversity mode, but That cannot be done in current Firmware. In diversity
the audio is fixed to A-b.
