Here is how the FM Receiver I made using the GNU Radio Companion.
(Basically, I was following this tutorial by VYE6Y on youtube.)
- Problem: Unfortunately for me, the GNU Radio gives no output. It opens a window as you can show below but no matter what I click or change, there is nothing to be heard. I think, the signal is being processed as the Bandpass spectrum can be seen(as shown in the 2nd image below, which shows the characteristic peak at the center-frequency of the channel).
I am using GNU Radio Companion 188.8.131.52, which is fairly new, on Windows 8.1.
What cannot be a problem:
- The RTL-SDR Dongle works. I can run it, for example, without any problems on CubicSDR, where it produces crisp clear sound.
- Also, I can run a different FM Receiver also made on GNU Radio Companion (though the parameters and scheme of the receiver are different and not quite tuned.)
- Any ideas why there is no sound?
