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.

73,
