"The LP-Pan works well with a decent soundcard, but suffers from the 
use of PowerSDR software, which is simply awful in my opinion, and 
lots of cabling."

Spectravue runs with the LP-Pan just fine.  I am using the 
recommended emu-0202 soundcard with a single LP-Pan.  The emu 
connects with a USB and requires two audio cables to the LP-Pan.  The 
LP-Pan uses a BNC coax cable to the K3 IF.  One one more connector 
for 12v.  That is more than the coax plus USB cable for the SDR-IQ, 
but I do not see what the big deal is.  But then if you saw the 
wiring in my shack you would understand that comment.

For dual-receive I use the M-Audio Delta-44 soundcard which has four 
audio cables and a sub-D15 cable to the computer.  But this is not a 
standard application.
