Acarsdeco2 Windows Download: Ultimate Setup & Troubleshooting Guide
Acarsdeco2 is a multi-channel ACARS (Aircraft Communications Addressing and Reporting System) decoder designed specifically for RTL-SDR dongles. Unlike other decoders that require audio piping from separate SDR software, Acarsdeco2 interfaces directly with your hardware to decode up to three channels simultaneously and serves the data through a built-in web interface. How to Download Acarsdeco2 for Windows
While the software is widely discussed in the aviation community, it is not open-source and is primarily distributed through the developer's official site.
Official Source: The latest versions are hosted at xdeco.org.
Version Selection: For modern Windows systems, look for the standard .zip archive. A legacy version (acarsdeco2_xp.exe) is also available for compatibility with Windows XP.
Dependencies: You must have the Microsoft Visual C++ 2013 Redistributable (x86) installed. Even on 64-bit systems, the 32-bit version (vcredist_x86.exe) is required for the software to run. Initial Setup and Configuration
Acarsdeco2 is a console-based program. It does not have a standard installer; instead, it is configured using command-line arguments, typically executed via a .bat (batch) file.
Find Your PPM Offset: Use a tool like SDR# (SDRSharp) to determine your dongle’s frequency correction (PPM) and optimal gain.
Edit the Batch File: Open the included ad2.bat file in Notepad and customize the following flags:
--freq: Set your local ACARS frequencies (e.g., 131.550, 131.725). --gain: Set the RF gain value found during testing. --freq-correction: Enter your dongle's PPM offset.
--http-port: The port for the web interface (default is 8080).
Run the Software: Double-click your modified .bat file to start decoding. Key Features and Enhancements
Multi-Channel Decoding: Monitor multiple ACARS frequencies at once without needing multiple SDR dongles.
Built-in Web Server: Access decoded messages in real-time by visiting http://127.0.0.1:8080 in your browser.
Database Integration: By linking a basestation.sqb file using the --db flag, you can replace raw aircraft IDs with actual registration and flight details.
Photo Support: Display aircraft images in the web interface by pointing the software to your photo directory with the --pictures flag. Troubleshooting Common Issues up to 3-channels ACARS SDR receiver for RTL2832 dongle

Monitoring the Skies: A Guide to AcarsDeco2 for Windows AcarsDeco2 is a specialized, multi-channel ACARS (Aircraft Communications Addressing and Reporting System) decoder designed for use with RTL-SDR dongles. It stands out in the hobbyist aviation community for its ability to decode up to three ACARS channels simultaneously and its streamlined web interface for browsing received messages. Key Features and Performance
For Windows users, AcarsDeco2 offers a robust command-line based solution for monitoring short text-based wireless communications between aircraft and ground stations. Unlike many basic decoders, it:
Decodes Multiple Frequencies: It can handle up to three different ACARS frequencies at once, provided they fall within the roughly 2.35 MHz bandwidth of a standard RTL-SDR dongle.
Integrated Interface: It directly interfaces with RTL-SDR hardware, eliminating the need for complex audio piping from other SDR software. Installation and Setup on Windows Downloading and Installing Acarsdeco2 on Windows To download
The Windows version of AcarsDeco2 is typically distributed as a compressed archive.
Download: Obtain the latest Windows version from official sources like xdeco.org.
Extraction: Unzip the archive into a dedicated folder on your PC.
Configuration: Users generally run the program via a batch file (e.g., ad2.bat). This file can be edited with Notepad to include specific parameters such as your dongle's PPM frequency offset, gain settings, and the desired ACARS frequencies.
Execution: Launch the batch file to begin decoding. Once running, open your web browser to the local address specified in the documentation to view incoming data. Use Cases and Data Types
By using AcarsDeco2, hobbyists can intercept a variety of interesting aviation data, including:
D-ATIS/Weather Reports: Real-time meteorological updates for specific airports.
Operational Messages: Pre-departure clearances, loadsheets, and OOOI (Out of gate, Off ground, On ground, Into gate) data.
Telemetry: Aircraft performance data and oceanic clearances.
AcarsDeco2 remains a premier choice for Windows users seeking a high-performance, lightweight tool for serious aviation monitoring. RTL-SDR Tutorial: Receiving Airplane Data with ACARS
Acarsdeco2 communicates directly with the RTL-SDR via the RTLSDR library. For Windows to recognize your SDR dongle as a generic radio device, you must replace the default Windows driver using Zadig.
Procedure:
Once completed, your SDR is ready for use with any native decoding software, including Acarsdeco2.
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.
This is where Acarsdeco2 shines. Even though it runs in a text window, it includes a built-in web server.
While the command is running, open your web browser (Chrome, Edge, Firefox) and go to:
http://localhost:8080
You should now see a live table of incoming ACARS messages, showing the flight number, registration, and message content.
