[Discuss-gnuradio] Problem DPSK Mod/ Demod - UHD USRP1 Blocks

Good morning,
I am working in digital communications specifically with dpsk modulation in gnu radio. I made a very simple dpsk modulation and demodulation testing flow graph
. this is the flow graph that I made for the transmitting part:
I hope to see any spectrum there! Also I hope to see a kind of
cosine signal in the scope at the final of the flow graph but I see
nothing!
I dont know what I am doing wrong. I am transmitting 16
samples/symbol with a symbol rate of 125 ksymbols/seg which is equal to
a sample rate of 2
Msamples/s at the TX and RX UHD - USRP block.The center frequency of
the UHD-USRP1 block was set at 2.4 GHz because the daughter board is a
RFX 2400.
Also when I run this program, I can see in the terminal :
UOUOOUOUOUOUOUOUOUOUOUOUOUOUOUOUOUOUOUOUO
Please, I hope anyone can help me. I have working on this for a long time and I dont know what else to do. Thanks!!
