Verified Setup Report: AcarsDeco2 on Windows AcarsDeco2 is a high-performance, multi-channel ACARS decoder console program designed for use with RTL-SDR dongles. It is widely considered a top-tier decoding tool because it directly interfaces with hardware to decode up to three channels simultaneously and provides a built-in web interface for real-time monitoring. System Requirements & Prerequisites Hardware: A compatible RTL-SDR dongle is required.
--freq: Specify your local ACARS frequencies (e.g., 131.550 MHz). --gain: Set your previously recorded optimal gain value. --freq-correction: Enter your dongle’s PPM offset.
Because AcarsDeco2 is a console program, it is best run via a batch file (.bat) rather than launching the .exe directly. Open Notepad and create a file named start_acars.bat in your program folder with the following structure:
