[Linrad] Question about 1 stereo audio and Diversity Map65 packet transmission

I'm currently running Linrad with a Delta-44 and using to feed packets 
to MAP65.  But I only have one downconverter and one polarization.  So 
far, I've configured it to put the same audio into both IQ inputs, and 
linrad displays 45 degrees. 

But I want to go the June VHF contest with a smaller PC an a USB sound 
card.  Can I use a single USB sound card and still configure linrad for 
2 x 2 IQ channels?  What happens with the undefined inputs?  It seems to 
_start_ to work on my desktop PC because Map65 reports the right Rx 
audio level and 0% error.  But after a minute, it reports "No Rx Data".

I'm currently testing with Linrad 2.56 and Map65 r1257 both running on 
my Linux box.

any ideas?
