Increase in transmit power on WFM Demodulator with a HackRF #1930

I'm not 100% sure if I'm just doing something wrong but while transmitting some WFM modulated audio using SDRangel and my HackRF the I guess amplitude off the lower signals just randomly increases. When listening to the signal using an RTL SDR there is suddenly a lot off noise in the audio signal. Moving the AFBW slider of the modulator fixes the problem but then it just appears again. I attached a screenshot of when this happened. I dont think this is intended behavior and I would also be surprised if it was a hardware problem but I dont really know seing as I'm kind of a noob when it comes to RF. Screenshot 2023-12-14 224137

Are you sure your audio file is correct? Does it happen randomly or always at the same point in the file?

EmilEmilchen commented 9 months ago

It happens on completely random occasions.

Edit: Yes, the audio file doesn't just play fine in VLC for example but I also tried other files as well. Sometimes the file also plays just fine. I'ts really annoying!
