ACARSDeco2 is a Windows utility that decodes ACARS (Aircraft Communications Addressing and Reporting System) messages from received radio signals and converts them into human‑readable text and useful logs.
As of the latest release (e.g., acarsdeco2 1.0.1):

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.
To run AcarsDeco2 on Windows, you must use a command-line interface or a batch file to execute it, as it does not have a standard graphical user interface (GUI). Instead, it generates a web-based dashboard that you view in your browser. 1. Prerequisites & Installation
Driver Setup: Use the Zadig tool to install the generic WinUSB driver for your RTL-SDR dongle. This is essential for the software to "talk" to your hardware.
Download: Get the latest Windows version (typically acarsdeco2_windows_xxxx.zip) from xdeco.org or authorized mirrors like Google Drive.
Extract: Unzip all files into a dedicated folder (e.g., C:\AcarsDeco2). 2. Configuration (Editing the Batch File)
You should not run acarsdeco2.exe directly. Instead, edit the included ad2.bat file using Notepad. Standard Batch File Template:
@echo off acarsdeco2.exe --gain 38.6 --freq-correction 0 --freq 131550000 --freq 131725000 --http-port 8080 pause Use code with caution. Copied to clipboard
--gain: Set your RF gain. Start with a value like 38.6 or 49.6.
--freq-correction: Enter your SDR's PPM offset (often 0 for TCXO models). acarsdeco2 windows verified
--freq: Specify the ACARS frequencies for your region in Hz (e.g., 131550000 for 131.550 MHz).
--http-port: Sets the port for the web interface (default is 8080). 3. Running and Viewing Data
Launch: Double-click your modified ad2.bat file. A command prompt window will open showing the decoder status.
Web Interface: Open your web browser and navigate to http://127.0.0.1:8080.
Troubleshooting: If you see a libusb_open error -12 or "Device or resource busy," ensure no other SDR software (like SDR#) is currently using the dongle. 4. Verification Tips
Signal Level: Use SDR# first to find the strongest local ACARS frequencies and verify your antenna reception before launching the decoder.
Data Feeding: If you use Virtual Radar Server, you can feed decoded data to it using the --outServer ad2:30008 flag. acarsdeco2 on Win 10 - Radar Spotting
Acarsdeco2 is a highly efficient command-line multi-channel ACARS decoder for Windows that directly interfaces with RTL-SDR dongles. It is often preferred over other decoders because it can monitor up to three channels simultaneously and features a modern web interface for browsing messages. Verified Setup Guide for Windows 1. Prerequisites & Hardware Prep An RTL-SDR dongle (like the RTL-SDR v3 NooElec NESDR ) and an appropriate VHF airband antenna. to install the WinUSB driver for your

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.

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.
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. If you prefer a verified GUI tool, use
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
