The only additional remark I'll make is that higher temperatures do a couple of things in the analog section of any receiver:If you can stand the temperature, your usrp should be fine. Matt
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. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
