| 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. | Includes a specific version ( acarsdeco2_xp
