Peter,

Let me try - If one listens to only one receiver in both ears, there is
no diversity reception (one receiver cannot do diversity).
If both receivers are mixed in any one headphone, the result will be
cancellations in that headphone due to the varying effects from both
receivers.   The best way to use diversity reception is to hear one
receiver in one ear and the other in the second ear, and let the brain
do the "deciphering".

Lyle has provided a means to allow the mixing requested.  Whether it
will be beneficial to the person(s) requesting it or not remains to be
seen.  You may use Lyle's mixing parameters and see for yourself if you
want.

The K3 receivers are the same, but they each use their own synthesizer -
that means they are not fully phased locked.  The diversity comes from
having two antennas that are physically separated, and perhaps have
different polarizations.
