You need to control the gain

Has anyone achieved a good received signal with RFX2400? When I worked without it , I had signals that went form 4000 to -4000. Now I'm using the deinterleave and the received signal is really noisy when I see it with the scope, and can't achieve up to -40 to 40 amplitude in the scope. How's that?
