[Discuss-gnuradio] spectrum_sense.py for usrp2

[adnan aftab]

Hey! 
I am using USRP2 with XCVR2450 daughter board. when i execute the usrp2_rx_cfile.py it appends the data into a file but the size of file is way too big. in fraction of seconds it generates a file of 1 to 2GBs. I dont know whats going on in it. I am using the default decimation of 16. 
Secondly, I got the  modified spectrum sense code for usrp2 from this forum i added fft mag_square part in it from usrp_spectrum_sense.py. whenever i run this code i get the error Failed to set center frequency. 
please help me out. I just want to collect the real time data for 2.4GHz ISM band.
