The brute-force method to answering your question is probably to look at the
operating temperature ranges in the datasheets for the major cmoponents. A
few things come to mind: the SD card (one of the cheaper components, I
suspect), the ethernet cable, and the resistors. These all might start
misbehaving at those temperatures. Could you keep the USRP in something like
a styroam cooler with ice on the bottom?
