It works here with the QT Frequency Sink. You have to double click.
Here's the test flow graph.

I am working on a receiver panadapter application. I would like to use the QT GUI Sink Clicked freq variable parameter to control the receiver local oscillator to recenter the spectrum. I tried a simple test flow graph using GNU Radio version 3.7.13. When I click on the GUI Sink spectrum, the
Hi Sarandis,
you can change the center frequency of the osmocom source by calling
the appropriate setter function. In GRC, that is automatically done
when you change the variable that you used there, for example with a
slider.
Now, you seem to want to do that automatically: just write a bit of
One way you could do this is with a signal generator - proabably a slowly
increasing ramp signal - which you sample with a probe block, and then the
value of the probe block is used to retune the hardware. Not at my GR
machine right now otherwise I'd attach a flowgraph to show how to do this.
I'm
Hi. Is there a way to change the center frequency of osmocom source, having
the video bandwidth steady, automatically at a given rate istead of a range
variable?

It looks like you used numpy and matplotlib to generate tcp.sink.PNG
and filesink.PNG. A possible issue might be that the
