Receiving 900MHz signal on USRP1

Hi
I am new to gnuradio. I have done installation of uhd and
gnuradio form buildgnuradio script successfully. Now I want to receive
900MHz signal from USRP1. when i run uhd_fft… it does not give any
significant result. and when i run usrp_wfm_rcv_pll.py it does not
receive any signal

Its terminal output is:

[email protected]:/$ cd usr/local/share/gnuradio/examples/uhd
[email protected]:/usr/local/share/gnuradio/examples/uhd$ sudo
python usrp_wfm_rcv_pll.py -f 900M

Hi usama,

The USRP1 is the platform. You use it with an RF front end, the
so-called daughterboard.

Radio does not support required frequency range.
Tells us that the daughterboard you use does not support the center
frequency of 900MHz.

Greetings,
Marcus
