is a high-performance command-line software application designed to decode Aircraft Communication Addressing and Reporting System ( ACARS ) signals directly from a raw radio signal (using an SDR dongle) or a baseband audio input . It is recognized by aviation enthusiasts and radio listeners as a powerful, multi-channel tool capable of simultaneously monitoring multiple frequencies.
Open any web browser and go to http://localhost:8080 . You should see a simple but functional page that displays the latest ACARS messages, aircraft information, and, if integrated with VRS, aircraft photos.
Traditional setups require tuning an SDR application (like SDR#) to a single frequency, routing the AM audio output to a program like PlanePlotter or MultiPSK via virtual audio cables. .
From the drop-down menu, select your device (typically labeled ). acarsdeco2 windows verified
Right-click inside your Acarsdeco2 folder and select -> Text Document .

: Edit the batch file to include your specific settings. A typical basic setup looks like this: You should see a simple but functional page
--gain 42.0 : Adjusts the internal RF gain of your RTL-SDR dongle. Modify this value based on your local signal environment.
When a system or software is "windows verified," it means that it has been tested and validated to ensure compatibility and performance on the Windows operating system. For ACARSDEC02, having a windows verified status guarantees:
| Option | Meaning | Example Value | |--------|---------|----------------| | --gain | Sets the receiver gain in decibels. | 38.0 (typical value; can range from 0 to 49.6) | | --freq-correction | Compensates for your dongle’s crystal inaccuracy, in parts per million (ppm). Find this value using rtl_test or SDR#. | 65 | | --freq | Specifies one ACARS frequency (in Hz). You may repeat this up to three times. | 131550000 (131.550 MHz) | | --http-port | Defines the port for the built‑in web server. | 8080 | | --outConnectUdp | Sends decoded data over UDP. The format pp:127.0.0.1:9742 sends data to PlanePlotter. | pp:127.0.0.1:9742 | | --logfile | Saves all decoded messages to a text file. | messages.log | From the drop-down menu, select your device (typically
Because AcarsDeco2 is a console binary, launching the .exe directly by double-clicking will cause the command prompt window to flash briefly and close. It must be executed via a customized Windows Batch File ( .bat ).
: 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
