Re: [Discuss-gnuradio] How to change center frequency automatically in rx usrp?

Hey Sinta,

Exactly!
You can find the example Sumit mentioned under
gnuradio/gr-uhd/examples/python/.
Either use this directly or copy over the required functionality to your
flowgraph.
However, it should be mentioned that this functionality could also be
achieved using messages
which makes it much easier to setup from within GRC.

Cheers,
