Windows Download - Acarsdeco2

If you are involved in aviation monitoring or Software Defined Radio (SDR), you have likely heard of Acarsdeco2. It is widely considered one of the most robust and efficient tools for decoding ACARS (Aircraft Communications Addressing and Reporting System) messages.

While Linux is the native environment for most SDR tools, running Acarsdeco2 on Windows is entirely possible and stable. This guide covers where to download it and how to get it running.

Since the raw Acarsdeco2 runs in a command prompt, some developers have wrapped it in a GUI. The most popular distribution for the Acarsdeco2 Windows download with a GUI is maintained by xmarco or via the RTL-ACARS bundles. However, the standalone CLI version is more stable.

Many ACARS decoding tools were originally developed for Linux. However, Acarsdeco2 has a native Windows port, making it accessible to the vast majority of hobbyists who run Windows 10 or Windows 11. The Windows version retains all core functionality while integrating seamlessly with popular SDR software like SDR# (SDRSharp) or standalone with an RTL-SDR dongle. Acarsdeco2 Windows Download

By completing an Acarsdeco2 Windows download, you gain the ability to:

Decoding ACARS messages is legal in most countries for hobbyist purposes, as these transmissions are unencrypted and broadcast over public airwaves. However, it is important to:

Once you have downloaded the .zip file, follow these steps: If you are involved in aviation monitoring or

ACARSDeco2 is a Windows application that decodes ACARS (Aircraft Communications Addressing and Reporting System) messages from VHF SDR audio or from prerecorded audio files, then displays/logs the decoded messages (airline position reports, weather, clearances, etc.). It’s typically used with RTL-SDR or other SDR receivers and integrated into hobbyist flight-monitoring setups.

Acarsdeco2 is a console application. It does not have a graphical user interface (GUI) by default. After extracting, here is how to start decoding:

Common command-line arguments:

Example for a typical setup:

acarsdeco2.exe -f 131.550 -f 131.725 -f 131.825 -p 1 -o messages.txt

This decodes three simultaneous VHF ACARS channels, applies a 1 PPM correction, and logs messages to messages.txt.
