Hello guys,
I have already installed the gnuradio on Ubuntu 8.10 (interpid) and the
dial_tone.py is working fine. Then, I was trying to test the
usrp_wfm_rcv.py with my USRP which takes input from 10.7M scanner but I
came to the following error:
ubuntuvm@ubuntuvm:~/Desktop/gnuradio-3.1.3/gnuradio-examples/python/usrp$
./usrp_wfm_rcv.py -f 10.7M
Traceback (most recent call last):

Any help is appreciated!
