[Discuss-gnuradio] daughterboard performance

I used XCVR2450 daughterboard for TX and RX on USRP2 and everything is fine.
Recently I began to use RFX2400 and DBSRX-LF, which I found out the performance are much worse than XCVR2450.
Observed from FFT plot, I found out there are some weird spectrum response using RFX2400 and DBSRX-LF respectively.
Furthermore, I am not able to decode some OFDM example anymore! (I compensated the correct carrier frequency already)

I am wondering if I need to update something like firmware, in order to use those two new daughterboards.
