    changing the center frequency to 900M
    changing the DAC rate to 100
    changing the address from 212 to 213

a script to receive aligned samples of a tone

    We use this program to measure the channel gain
    of a single input multiple output channel.

    Idea is to make one code with tx and rx usrps. Till now I have successfully
    generated samples of a given frequency using the liquid's nco_crcf object
modified simo_tone.cc to run Tx and Rx concurrently

    added rx_streamer and code to save the captured samples to a file.
