Forum: GNU Radio Basic USRP transmission

I'm trying the USRP using GNU Radio but I cannot receive successfully. 
I'm
using the following flowgraphs in GRC:

TX:
Vector Source => Packet Encoder => DPSK Mod => UHD Sink

RX:
UHD Source => DPSK Demod => Packet Decoder => File Sink

I tried using benchmark_tx and benchmark_rx and the packages got through
without errors. However, in my GRC example, nothing gets written to the
file. Why is that? How can I send a simple binary file through the UHD?

Are you looping
back to the same USRP, or different ones?

What type of daughtercards?


If looping back, are you using an attenuator?
