Re: [Discuss-gnuradio] RX Channel Out Of Range

[Ben Hilburn]

Hi Azza -

We have noticed that problem if you have copied UHD source / sinks from another flowgraph into the one you are using. Try deleting the UHD blocks and re-creating them in your flowgraph and see if that fixes the problem.

There is some bug in copying those blocks between flowgraphs in GRC, I think.

Cheers,

Ben

Hi All,

I am using GNU Radio Companion version 3.6.2.

When I execute a simple flowgraph (containing two blocks: USRP Source and WX GUI FFT Sink), it generates the following error:

RuntimeError: LookupError: IndexError: multi_usrp: RX channel 214957620880 out of range for configured RX frontends

Note that when I execute a flowgraph that does not deploy USRP, it works fine.

Does anyone have an idea how to fix this error?

Any help is appreciated. Thank you.

Regards,

Azza
