[Discuss-gnuradio] Problem in uhd_fft

Hi,
      I am using a basic tx and basic rx daughterboard for transmission and reception. The spec says basic tx and basic rx run from 0 to 250 MHz. But when i run transmitter and check the uhd_fft at receiver, after 32 Mhz, there is no signal. If i set the transmitter frequency in my flowgraph as 33 MHz, I don't get a signal at 33 Mhz, But when i enter frequency as -31Mhz in the uhd_fft i get a received signal on my fft. why does this happen? If it's in the range of daughter board it should be receiving it at that particular frequency right.
