Re: [Discuss-gnuradio] spectrum chunk

[Martin Braun]

On a USRP1, you can get 8 MHz across the wire (16 MHz if you go to 8 bit 
samples). This is a matter of USB2.0 not being able to transport more data.

Once you have a chunk, channelization is the way to go, and GRC is 
generally a good tool to use.
