You haven't mentioned which daugtercard(s) you're using on the TX and RX
sides.
Also, your tones are going to be offset from the center frequency by
less than 1KHz, so they'll
be hard to see in the DC-offset removal process.
Try tuning your receiver up or down a couple of KHz and see if your
tones show up in
the FFT.
