But not a second antenna for diversity reception.

Bruce also asked, "short of having a second subreceiver in the K3 (which 
I do not have) - When operating Split, I know you can quickly switch 
between DX and calling stations by holding the "REV" button. The problem 
of course is you can only hear one or the other. Is it within reach of a 
simple software enhancement from our heroes at Elecraft to route these 
two audio signals to the left and right headphone channels from VFO A 
and B?"

Answer:

This is possible using SDR software with an I/Q feed from the K3 IF. 
Check out the LP Pan unit and NaP3 SDR software. You will also need a 
suitable sound card with stereo inputs and outputs. This software 
creates two SDR receivers within the computer, which can then be fed to 
the computer's sound card for playback. You plug your headphones into 
the computer's sound card output.

The better the sound card, the better this will work. The wider the 
bandwidth of the sound card, the greater the width of the spectrum you 
can display. The software is free.  LP-PAN costs $250.  The recommended 
ASUS USB sound card costs $65.
