In the Flex series, a second RX is a matter of more software and the memory

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.
