I'd suggest trying lowering your transmit power, as the amplitude you are using is driving the RFX into non-linearity, and with the raised cosine filter you are using, the modulation is no longer constant envelope, so you are generating unnecessary distortion. The RFX boards typically remain linear up to an output amplitude of about 2000. Similarly, on receive, it looks like you are using the default mid-point gain of the RFX, which likely too high for a path loss of only 40dB. I'd suggest experimenting with lower receive gains to see if things improve.
