Acarsdeco2 is a command-line utility developed by the creators of modesdeco. Unlike older, clunky decoders, Acarsdeco2 is designed to run efficiently while monitoring multiple frequencies simultaneously. It processes signals directly from inexpensive USB RTL-SDR dongles and outputs the decoded messages in a clean format. Key features include:
Acarsdeco2 can send its data directly to PlanePlotter over your local network. In the command line, you would add something like --outConnectUdp pp:192.168.0.100:9742 , where 192.168.0.100 is the IP address of the computer running PlanePlotter.
If you see no messages after a few minutes, try adjusting the --gain or double‑check your frequency correction. Acarsdeco2 Windows Download

Save and close your text editor. Double-click your start_acars.bat file. A Command Prompt window will launch, initializing your RTL-SDR dongle and listening to the programmed frequencies. Accessing the Web Interface
--freq : Specifies an ACARS frequency in MHz. You can repeat this flag up to three times to monitor multiple channels simultaneously, provided they fit within the SDR's operational bandwidth window (usually within 1-2 MHz of each other). To see the full list of options, run:
The Aircraft Communications Addressing and Reporting System (ACARS) is a digital datalink system. Airliners use it to transmit text-based messages to ground stations. These transmissions include real-time telemetry, flight plans, weather updates, and pilot-to-dispatcher communications.
