If you can stand the temperature, your usrp should be fine.

Matt

The only additional remark I'll make is that higher temperatures do a couple of things in the analog section of any receiver:

     o The LNA gain will be somewhat lower (perhaps as much as 0.2dB or so)
o The LNA noise temperature will be higher, perhaps by as much as 15K or so

Crystal oscillators generally wander all over the place with temperature, but the USRP2 uses, as I recall, a TCXO, so it should be no
  worse than at room temperature.
