You are right, unless your device is pre-approved by the FCC you can't
legally transmit in unlicensed bands.

I was under the impression that the USRPs status as 'test equipment'
allowed transmission in unlicensed bands (like the ISM) without
needing the part 15 approval as long as it was below a certain
effective radiated power level, as if a user were developing a new
product prior to part15 certification.  That may not be true.
