never had a rig that would do this before, so I am not familiar with
the concept.
I admit to not keeping up with the K3 feature list and manual. Go
ahead and flog me now.

Stan,
Diversity reception has been around for quite a while.
It involves having 2 receivers connected to different antennas at
different locations. Best at HF if one is horizontally polarized and
the other vertical, but will work if the two antennas are separated by
a wavelength or so even if the polarization is the same.
The idea is that the different antennas will not suffer from QSB and
other sources of fading at the same time. If you have only one antenna
for each band, diversity will buy you nothing.

www.ei6iz.com has three stereo sound clips of diversity reception - one
receiver in each ear.
Scroll down to the section on the KRX3, click to open a sound clip and
listen with stereo headphones.
