I'm trying to make an FM radio that would search for radio stations automatically and then let the user choose a station using an rtl-sdr. I wanted to use a QT GUI Chooser block to show the found channels, however now I don't think this would work, I did a few tests and then noticed the parameters for list values and labels are not underlined (which I understand means run-time adjustable). Is there a way to make this work or anything else I could use?
I'm using gnuradio 3.8.1 .
