Error 1: "rtlsdr.dll not found" Problem: Windows cannot find the RTL-SDR library. Solution: You need to install the RTL-SDR binaries. Download rtlsdr.dll and libusb-1.0.dll from the rtl-sdr-release package (or copy them from a HDSDR installation) into the same folder as acarsdeco2.exe . Error 2: "Failed to open device" Problem: Zadig driver not installed correctly or another SDR program (SDR#, HDSDR) is still running. Solution: Close all other SDR software. Re-run Zadig and ensure WinUSB is installed for Interface 0 and Interface 1 of the RTL-SDR. Error 3: No messages decoded (Only static) Problem: Frequency is off, or gain is too low. Solution: ACARS signals are narrow-band FM. Set gain between 30 and 45. Ensure your antenna is indoors near a window; ACARS is generally strong, but basement setups won't work.
