All I can say is these devices are not built to be radiation tolerant to say nothing of radiation hardened. Keep in mind the laptops (not used for safety critical things) on the ISS have to rebooted daily because of Single Event Upset (SEU)s that lock them up.

Interesting time to talk about Software Defined Radios.

NASA's SCaN Testbed with 3 Software Defined Radios is launching onboard the Japanese HTV-3 Unmanned cargo vehicle in 15 days. (July 21st)

It's an experimental payload that will be bolted to the exterior of the International Space Station and perform communications experiments with the 3 SDR's contained in the payload.
