Thanks for the response.
I am using a USRP2 N210 with the shortwave receiver daughterboard. When
was playing around, I was getting an error when I set the sample rate on
the USRP source to 30MHz, and was told it had something to do with
100 by 30 and not getting an integer (you get 3.33333), so it was
recommended I use 25 or 50, with 25 giving more resolution on the
If I am setting the rate to 50MHz on the source and 30MHz on the FFT
and I am actually seeing (and ultimately recording with a file sink) the
whole shortwave spectrum, I will be satisfied.

Hello, first I think you meant sample rate, not size. Who said you cant
30Mhz, what kind of hardware are you using? Lastly the FFT algorithms do
not deal with frequency in that way, you are still seeing 0-50Mhz
just the label now says 50Mhz.
