Re: [Discuss-gnuradio] usrp_spectrum_sense.py raw iq samples

[Julian Arnold]

Hi Mallesham,

the easiest way would probably be to create your own simple flowgraph
using GRC like so:

|---------------------|                  |-----------------|
| USRP Source   | ----------> | File Sink       |
|---------------------|                  |-----------------|

However, remember that writing to a file can be slow. You might want to
consider using a ramdisk.
Also, what whole Wifi band are you talking about? Depending on your
hardware configuration you might run into additional problems.

Cheers,
Julian
