Re: [Discuss-gnuradio] Any friend working on Hydra from UT austin? How about the performance.

I only have one USRP, and I believe only like 2% of people here have
more than one for that kind of testing, so there's not many here with

the answer. Although I believe the answer could be derived from the
available bandwidth and noise.
