if you want to listen to local Dallas police chatter I've set up an #sdr server using openwebrx and a radxa zero along with an rtl-sdr dongle hooked up to a dipole antenna. just click on the bookmarks at the top to listen to various signals depending on waterfall chatter https://sdr.minnix.dev/#freq=460076485,mod=nfm,sql=-39
@GoatsLive yeah i can see it as a great use for an unused pi.
@minnix That's pretty cool! Had not heard of that software before, but downloading to Pi image as it would be a good use for an unused Pi I have laying around.
