Installation and Setup for Windows (Verified Method)

Once you have your verified acarsdeco2.exe, follow this battle-tested setup process:

Quick summary (verified)

• ACARSDeco2 runs on Windows 10/11 (x64 recommended).
• Requires an SDR (Software Defined Radio) device (commonly an RTL-SDR) or a WAV input from a receiver.
• Decodes VHF ACARS (typically 131.725 MHz, 131.125 MHz, or nearby frequencies depending on your region).
• Outputs decoded messages to a GUI, text logs, and can forward to network services (e.g., ACARS servers or local parsers).

Basic configuration

1. Launch ACARSDeco2.exe.
2. Input source:
   • SDR: choose the RTL-SDR (or other) device from the device menu, set sample rate to recommended value (e.g., 2.4 MSPS for RTL-SDR).
   • Audio/WAV: choose the correct audio input (line-in) or load a WAV file containing recorded demodulated audio.
3. Frequency: set to the ACARS VHF frequency used in your area (common center: 131.725 MHz; many regions use ±0.025–0.1 MHz offsets).
4. Mode: set to AFSK/ACARS decoder mode (if there’s a modulation choice).
5. Audio and gain: use moderate RTL gain (e.g., 30–40 dB) and adjust to avoid clipping; enable AGC if available.
6. Decoding options: enable automatic message saving/logging and timestamping.
