My issues tend to fall in both categories.  Other folks claim to get 
sensitivities around the 1uV range and the specs say something more like 
3uV.  My initial tests were looking like I was getting much less than spec, 
but without knowing if I was testing it correctly, I wasn't sure if 
something was wrong with the radio or my tests.  Still not quite sure, but 
I think it was the later.
