I am having trouble getting clear sounding audio out of my HackRF One receiver in NBFM mode. The audio sounds raspy. I am using an external 10Mhz GPS disciplined TCXO clock. I ran all the gains down and up but the raspy sounding audio persists. RF=0, IF=16, BB=16 as default gains. Here is a link to my grc setup. http://hamsoftware.org/SDR/NBFM_quad.grc.png
I am got WBFM working pretty well. Even have RDS on it. I am running this on Ubuntu 16.04. I used the Ubuntu binaries for GnuRadio. I am sure I am making some sort of mistake. Oh, I also tried this on both a USB-2 and USB-3 port. No difference. I am new to SDR. Trying to find a good source for grc examples also. Heck of a learning curve.
