Thanks Ed, yes, I hadn't looked closely enough at the pictures. The "higher sensitivity" I mentioned came from the second line of the "Features" section near the bottom of: http://www.semiconductorstore.com/cart/pc/viewPrd.asp?idproduct=41599
"Enables indoor use -173 dBW acquisition and -185 dBW tracking" although admittedly right underneath that in the "Specifications" section is does say: "Track Sensitivity: -155 dBm" A cased of "specmanship"?
