To run Acarsdeco2 reliably with custom settings, you must execute it via a Windows Batch script ( .bat ).

Can feed data to external software like PlanePlotter or Virtual Radar Server (VRS) via UDP.

ACARSdeco2 is highly capable. Below are verified advanced command-line arguments:

| 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. |

: It can output data to other aviation tools like COAA PlanePlotter or Virtual Radar Server (VRS) for mapping and enhanced aircraft tracking. Installation & Verification Steps For verified operation on Windows systems: acarsdeco2 on Win 10 - Radar Spotting

– acarsdeco2 is a lightweight, console-based software-defined radio (SDR) decoder specifically designed to receive and decode ACARS (Aircraft Communications Addressing and Reporting System) messages using an RTL-SDR (RTL2832U) dongle on Windows. Developed by Sergsero, it directly controls the RTL-SDR hardware and processes ACARS transmissions from VHF aviation bands, displaying decoded messages in real time, hosting a local web interface, and outputting data to other software via UDP/TCP networking.

@echo off cmd /c acarsdeco2.exe --device-index 0 --gain 38.0 --freq 131.550 --freq 131.725 --freq 131.825 --http-port 8080 pause Use code with caution.
