Problem receiving data packages with benchmark_rx.py

Hi,

I’ve trying to transmit data packages using the benchmark examples
(narrowband psk mod) we have been able to see the spectrum at the
receiver using the FFT but no package it’s seen in the terminal.

These are the parameters entered at the receiver computer.

./benchmark_rx.py --rx-gain=30 -f 435.215M -v -r 500000

This the equipment I am using:
USRP1
Daughtherboard: RFX400
OS:Ubuntu 10.04

If you need more info let me know

Thanx
