RE: Beaglebone Black Radio challenge - First step(setting up SDR)

Nice post, Bhaskar!

Last night I followed your steps to setup rtl_test, with the Adafruit radio antenna attached.

I am super new to rtl and eventually found the rtl_fm command. I tried different combinations of rtl_fm piped to sox and aplay, but was only successful in hearing radio static from the speakers.

Can you provide some guidance on how to issue an rtl command to play FM frequency 104.5, and output the sound to speakers?

Thanks,

Roberto

Hi Nitin,

Great stuff! And glad you're documenting it step-by-step. Looking forward to trying this out too.

I've only tried the SDR dongle on Windows so far.

(by the way a carriage-return is missing before "rtl_test -t", so you might want to edit that).

I think the USB audio should work just fine as soon as you plug in the USB soundcard and then direct the audio to USB soundcard instead of HDMI, depending on the software application (default may still be HDMI, not sure). See here for some old notes on this, to know what the name of the USB soundcard device may be.
