The gain is the same on the USRP2 at all decimation rates.

And are the half-band filters used at all decimations, or only some of them?

Just trying to rationalize some observed behaviour.

One is used when doing even rates, and both are used when doing multiples of 4. Odd rates don't have a halfband, and so are not suggested.
