Even simpler math ...
1 out of 20 failing is likely worse than 1 out of 20,000 ...

G0MRF is correct of course ... SuitSat-2 will test the SDX ...

I'm not sure where anyone thinks this "debate" is going - it IS going 
to be an SDX and not analog ... this has already been decided on as 
far as I can see ... and I sat through a lot of talks at the DCC 
about this stuff. Because that is: a) what the guys doing all of the 
work want to do, and b) what is required to provide the services 
desired for the power budget available.

However, we might be able to put a spark-gap up there if we need 
something "rad-hardened" ...
