Hi all, I am zia. I successfully installed softwares Uhd_003.006.002/GNU Radio 3.6.5.1/Boost 1.43.1 and gmr on Ubuntu 12.04,but when i run signal capturing command I receive no file at output:

//*********************************************************************//
zia:~/osmo-gmr/utils/gmr_multi_rx$ sudo ./gmr_multi_rx --gmr1-dl 943 -a RX1 -S A:0 -T 10 --add=usrp2

linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.006.002-rc2

    Given gmr1-dl ARFCNs:     943 = 1554.468750 MHz
    Required bandwidth is: 31.250000 kHz
   
    Creating the UHD device...

zia~/osmo-gmr/utils/gmr_multi_rx$

//*****************************************************************************//

(I am running USRP NI 2930)

Any help will be highly appreciated.

Thanxs
Zia
