I’m using an RTL-SDR dongle on a Raspberrypi for Acars. If I were to connect an audio cable to the jack on the Rpi, would I be able to get audio and then pipe that to another app? I’ve already tried it, even went to the Rpi configurations and enabled the audio thru the HDMI / jack, but it doesn’t seem to work?
ACARS is text messaging for aircraft .... you want to listen to telex? in-depth answer is yes .. you could pipe the output from SDR device tuner to ALSA or something and shoot it out the audio jack .... but it's not going to be useful for anything unless you have a Telex machine sitting around If you just want to decode ACARS then https://github.com/TLeconte/acarsdec
Yes, I’m using the Leconte program. What I like to accomplish is use this audio in my PC so that the Acars decoder in Plane Plotter, could use it as well. As it stands right now, I’m piping audio from a scanner into a USB audio card plugged to my PC. But that’s limited to one Acars freq whereas the Leconte application, has the capacity to use more than one frequency.
