AcarsDeco2 is a highly efficient, multi-channel command-line decoder for ACARS (Aircraft Communications Addressing and Reporting System) data
, compatible with Windows and several other platforms. It is widely recognized in the radio monitoring community for its ability to directly interface with RTL-SDR dongles and decode up to three channels simultaneously. Core Functionality and Setup on Windows
AcarsDeco2 functions as a "console program," meaning it is typically executed via a batch file rather than a standard graphical interface. Users generally download the Windows version from and unzip it into a dedicated folder. FlightAware Discussions To run the program effectively on Windows: Driver Configuration : You must use a tool like
to install the correct WinUSB drivers for your RTL-SDR dongle; otherwise, Windows may default to generic DVB-T drivers that prevent the software from accessing the hardware. Batch File Execution : A sample batch file (often named
) is included in the download. Users modify this file using a text editor to include specific parameters such as their dongle's PPM frequency correction, gain settings, and the frequencies they wish to monitor (e.g., 131.550 MHz 131.725 MHz Web Interface
: While it runs in a command window, AcarsDeco2 provides a built-in web server. Once running, you can view real-time messages and aircraft data by navigating to
AcarsDeco2 is a specialized console-based SDR (Software Defined Radio) multi-channel decoder designed for aircraft ACARS (Aircraft Communications Addressing and Reporting System) signals. It is widely recognized in the aviation enthusiast community for its ability to decode multiple frequencies simultaneously using a standard RTL-SDR dongle. Key Technical Content & Setup RTL-SDR Tutorial: Receiving Airplane Data with ACARS
AcarSDeco2 is a multi-channel ACARS (Aircraft Communications Addressing and Reporting System) decoder for Windows that directly interfaces with RTL-SDR dongles. It is known for its high decoding performance and ability to monitor multiple frequencies without needing separate audio piping software like Virtual Audio Cable.
While there is no single feature officially named "acarsdeco2 windows verified," the term likely refers to the software's ability to run reliably on Windows systems (including Windows 10 and older versions like XP) when configured with the necessary Visual C++ Redistributable 2013 components. Key Features of AcarSDeco2 on Windows
Multi-Channel Decoding: Decodes up to three ACARS channels simultaneously using a single RTL-SDR dongle. acarsdeco2 windows verified
Built-in Web Interface: Features a native web server that displays received messages, aircraft photos, and flight information in a readable format through a browser.
Direct Hardware Interface: Communicates directly with the RTL-SDR, eliminating the need for external SDR software (like SDR#) or complex audio routing during active decoding.
ADS-B Integration: Can extract supplemental data and live positions if integrated with a Virtual Radar Server (VRS) URL, displaying aircraft images and routes alongside ACARS text.
Data Output Options: Supports piping decoded data to other applications like PlanePlotter or BaseStation via UDP or TCP server outputs.
Customization via Batch Files: Runs as a console program configured through .bat files, allowing users to specify gain, frequency correction (PPM), and folders for silhouettes or aircraft photos. Requirements for "Verified" Operation
To ensure the software runs correctly on Windows, users typically need:
Visual C++ Redistributable 2013: Specifically the x86 (32-bit) version, even on 64-bit operating systems, to avoid "missing .dll" errors.
Zadig Drivers: The standard RTL-SDR USB driver must be installed for the hardware to be recognized by the console application.
Frequency Calibration: Determining the dongle's PPM offset in another program (like SDR#) beforehand is essential for accurate decoding. AI responses may include mistakes. Learn more RTL-SDR Tutorial: Receiving Airplane Data with ACARS 📡 Alternative verified Windows tool (if you need
If you prefer a verified GUI tool, use ACARSDeco2 GUI (community‑made wrapper) or simply use SDR# + ACARS plugin – but the core acarsdeco2 remains the most efficient on Windows.

Verified Guide: Using ACARSDeco2 on Windows ACARSDeco2 is a highly efficient, multi-channel software decoder designed to receive and process Aircraft Communications Addressing and Reporting System (ACARS) messages directly through RTL-SDR dongles. Unlike older decoders that require audio piping from external software, ACARSDeco2 interfaces directly with your hardware to decode up to three frequencies simultaneously. Key Features and Performance
Multi-Channel Decoding: Monitor up to three ACARS channels at once using a single RTL2832-based dongle.
Integrated Web Interface: Browse received messages in real-time through a built-in web server.
Direct Hardware Interface: Eliminates the need for virtual audio cables or complex audio routing.
Data Integration: Can feed data to external software like PlanePlotter or Virtual Radar Server (VRS) via UDP. Let me know if you need:
XP Compatibility: Includes a specific version (acarsdeco2_xp.exe) for older Windows XP systems. Verified Installation for Windows
ACARSDeco2 is a "portable" console program, meaning it does not have a traditional installer and should be run via a command prompt or batch file.
Driver Setup: Ensure your RTL-SDR is correctly set up using Zadig to install the necessary WinUSB drivers.
Calibration: Use software like SDR# to find your dongle's PPM frequency offset and optimal gain settings. Record these values before closing SDR#.
Download and Extract: Download the Windows version from xdeco.org and unzip it into a dedicated folder (e.g., C:\ACARS\).
Create a Batch File: Create a .bat file in the same folder to launch the program with your specific parameters. A typical command looks like:acarsdeco2.exe --gain 38 --freq-correction 65 --freq 131550000 --freq 131725000 --http-port 8080
Run and Monitor: Launch the batch file. Open your web browser and navigate to http://127.0.0.1:8080 to view the live message feed. Critical Configuration Flags DUMPVDL2 and ACARSDECO2 on the same PI3
Often due to driver conflicts. Re-run Zadig and ensure your RTL-SDR is set to WinUSB (not libusb0). Then restart your PC.
