Acarsdeco2 Windows [best] Download Official
Check that you have the installed. Also, verify that your command line does not contain spaces where they should not be — for example, --no-uplink off is correct, but --no uplink off (with a space) will cause an error.
Before running Acarsdeco2, ensure your hardware and drivers are correctly configured. Hardware Needed:
If you want to decode these text-based operational messages directly on your PC using a RTL-SDR dongle, is one of the most efficient, lightweight, and powerful command-line decoders available.
: Look for a .zip archive labeled for Windows (usually acarsdeco2_windows_YYYYMMDD.zip ). Acarsdeco2 Windows Download
is a highly efficient, multi-channel command-line ACARS (Aircraft Communications Addressing and Reporting System) decoder designed specifically for RTL-SDR dongles and other software-defined radios . Unlike traditional software that requires audio piping via virtual cables, Acarsdeco2 interfaces directly with your hardware, decoding up to three separate ACARS frequencies simultaneously within a 1.4 MHz bandwidth. This guide covers the complete workflow for downloading, configuring, and running Acarsdeco2 on Windows. Technical Prerequisites
Because Acarsdeco2 is freeware developed by an independent hobbyist, it does not have a centralized commercial website. Finding a clean download link requires knowing where the hobbyist community mirrors the files. 1. Trusted Community Portals
: Reads RTL dongles directly, bypassing the need for "virtual audio cables". Check that you have the installed
| Option | Description | Example | | :--- | :--- | :--- | | --gain | Receiver gain in dB (determine optimal value using SDRSharp) | --gain 38.0 | | --freq-correction | Dongle oscillator correction in parts per million (PPM)—critical for accuracy | --freq-correction 65 | | --freq | ACARS frequency in Hertz (up to 3 channels, max range difference 1.3MHz) | --freq 131550000 | | --http-port | Port for built-in web server (default: 8080) | --http-port 8080 | | --agc | Enables automatic gain control（optional） | --agc | | --logfile | Saves all decoded messages to a file | --logfile C:\Logs\acars.txt |
Decoding ACARS messages is legal in most countries for hobbyist purposes, as these transmissions are unencrypted and broadcast over public airwaves. However, it is important to:
Because it bypasses graphical user interfaces (GUIs) and virtual audio routing, it runs smoothly on older hardware and background servers. Hardware Needed: If you want to decode these
– Optimized for the air band (118–138 MHz). An air band bandpass filter can help reduce interference.
Displays real-time data, aircraft maps, message logs, and reception statistics without needing third-party software.
