To determine your dongle’s frequency error:
So, how do you tune in and read these messages from your computer? This is where acarsdeco2 comes in. Developed by a user known as "sergsero," this program is a multi-channel console-based ACARS decoder.
: You must install the 32-bit architecture version ( vcredist_x86.exe ), even if your version of Windows is 64-bit. This is necessary because the Windows binary of AcarsDeco2 is compiled as a 32-bit application. Step 3: Unzip and Organize Files
is a highly efficient, command-line multi-channel ACARS (Aircraft Communications Addressing and Reporting System) decoder designed to interface directly with low-cost hardware like an RTL-SDR dongle. Developed by sergsero, it stands out because it decodes up to three channels simultaneously without needing external audio-piping software. This article provides a comprehensive, verified guide to setting up and running AcarsDeco2 seamlessly on modern Microsoft Windows operating systems. Why Choose AcarsDeco2? acarsdeco2 windows verified
Download the verified archive package (such as acarsdeco2_windows_20181201.zip ).
While the application is highly stable, setting up requires precision. This verified, step-by-step guide covers how to bypass common driver conflicts, configure your frequencies, and establish a reliable runtime environment on modern Windows operating systems. Why Choose Acarsdeco2 for Windows?
One of the most powerful features of acarsdeco2 is its ability to decode up to as long as they fit within the dongle's bandwidth (typically within a ~1.3 MHz range). This is a massive upgrade from old-school methods that required an expensive scanner and could only monitor one frequency at a time. To determine your dongle’s frequency error: So, how
: Necessary to replace default Windows USB storage or TV tuner drivers with generic WinUSB drivers.
The official and most up‑to‑date Windows version is hosted on the developer’s website xdeco.org . As of the latest available version, the most stable release is acarsdeco2_windows_20181201.zip .
Double-click start.bat . If the command window remains open and displays message data, your installation is active. Open a browser to http://localhost:8080 to see the map and live message logs. Troubleshooting Tips : You must install the 32-bit architecture version
designed for Software Defined Radios (SDR) like the RTL-SDR . When correctly configured on Windows 10 and Windows 11 , it provides a stable console environment capable of decoding up to three radio channels simultaneously. This article provides a comprehensive walkthrough to get AcarsDeco2 verified, functional, and fully integrated with secondary data streams on your Windows system. Why Choose AcarsDeco2 for Windows?
The standard RTL-SDR Zadig driver must be installed; if errors like "Bad file descriptor" occur on Windows 10, reinstalling the Zadig driver often resolves them.
Windows frequently overwrites custom SDR drivers during system updates. You must verify your device is utilizing the generic WinUSB layer. Plug your RTL-SDR dongle into a USB port. Download and launch (Run as Administrator). Navigate to Options -> Check List All Devices .
| Feature | Parameter | What It Does | | :--- | :--- | :--- | | | --gain | Adjusts the sensitivity of the SDR dongle. You can set a fixed value (e.g., 49.6 ) or use --agc for automatic control. | | Frequency Correction | --freq-correction | Corrects for the dongle's internal oscillator drift (in parts per million, PPM). This is absolutely critical ; without proper correction, you won't decode anything. | | Set Frequencies | --freq | Specifies which ACARS frequencies to listen to. You can use this flag multiple times (up to 3) to monitor different channels (e.g., --freq 131550000 --freq 131725000 ). | | Web Interface | --http-port | Launches a built-in web server, letting you view decoded messages in a clean interface in any browser (default port is 8080). It's much easier to read than the command line scroll. | | Databases for Airlines | --frdb , --db | Points to .sqb database files containing airline and flight route info. This allows the web interface to display airline names and logos alongside the raw messages. | | Logging | --logfile | Saves all the decoded messages to a text file for later review or analysis. |
