You can tell the "USRP source" block to tune to a specific frequency on
a specific time with a "GNU Radio message passing" message. That would
be how I'd recommend to implement a scanner.
They're also used for pushing other kinds of data around, yes :)

Hi Marcus,
I was reading your reply. I had implemented a similar system but on a
different band (TV).
I did not understand this section of your reply.
If you actually want to retune (e.g. because your device bandwidth is

Hi Anderson,
Yes, that is possible.
Detection purely based on power should be pretty simple; now, you're
using "uhd_fft.py", which indicates you're using an Ettus USRP; these
devices often are capable of capturing *all* of the GSM downlink in a
specific Band (e.g. EGSM900) at once (that only being
Good afternoon everyone.
I'm starting in radio frequency. Making analysis of spectra using
uhd_fft.py in search of a channel (ARFCN) not used by the operator (GSM),
one doubts arose: is it possible to automate this process? A script,
library, etc. running a scan on a GSM frequencies of range and fi
