FM Stereo Reception on rPi 3

[dononeil]

I just picked up an rtl-sdr dongle, and quickly got it to work on tuning in FM, but I was un-aware that the rtl-sdr tools in linux are only mono.

I've read that there is a patch to add stereo, has this been incorporated into the mainline code yet? If not, where can I get the patch for the latest code base and re-build the tools?

My goal is to get a simple command line FM wideband stereo receiver going on the rPi 3 so I can set it up to launch on startup.

Thanks!

What tools are you using? GQRX supports stereo

I'm using the rtl_sdr/rtl_fm command line.

Does GQRX support non-gui command line playback like rtl_fm does?

Thanks!

Was just playing around with GQRX, cool app, but I need a command line option with low-overhead. Any suggestions on how to get FM-Stereo playback from the CLI?

Thanks!

Try and see if you can get SoftFM to run, this should support stereo

Thanks, that was pretty straightforward of a build and seems to work good!
