bladeRF FM Receiver

Post by ratz »

Hi nuand team, hi forum members,

i am new to SDR and wanted to recreate a basic first SDR application using GNURadio - a FM Receiver. I was following tutorials on the internet, but i do not seem to get it working probably. I can not generate any audio output.
I attached my .grc file: bladeRF_rx_my_fm_receiver.grc

Here, you can find screenshots of the GUI and the GRC File in GNURadio-Companion:

I would be really glad, if you could tell me if you see a mistake and how to fix it.

Greetings!

Do you need additional information that i can provide?
Hint: I updated my bladeRF v1 already to the latest Firmware available.

I know this is a year later, but I'm new to the bladeRF.

I tried your script, and it works fine on my bladeRF v2. I get audio output.

The only change I had to make was the option on the QT-GUI control. I think its operation changed a bit between versions of GNuRadio, and the default value needed to be an integer index and not a frequency in MHz.

So if you weren't getting audio output, there was something wrong with the way audio was configured on your box.
