Hello,
The set-up that I think I did a pretty bad job describing earlier goes 
USRP ---> tx antenna ~~~~~~ AIR GAP ~~~~~~~ RX antenna ----> some 
components from an old microphone -----> PC sound card.  I believe your 
theory about non-linearities creating a sort of envelope detection is 
accurate, but I think it might be the non-linearities of the 
microphone's amplifier that are the component that are doing the 
envelope detection.  I've begun reading more about Nyquist rates.  
Thanks for all your responses, they've been very educational.

Evan
