While this guide focuses on VHF ACARS, it's worth noting that HF ACARS (HFDL) also exists for long-distance communications. Decoding HF ACARS requires different hardware and software approaches, typically using a more capable receiver rather than a basic RTL-SDR dongle.
Acarsdeco2 is an multi-channel ACARS decoder created by programmer Serg Serg. Unlike older software that requires audio routing via Virtual Audio Cable from an external SDR program, Acarsdeco2 connects directly to your RTL-SDR dongle. Key Features: Acarsdeco2 Windows Download
Many third-party sites bundle malware with SDR tools. The only safe and official source for the Acarsdeco2 Windows download is the project’s GitHub repository. While this guide focuses on VHF ACARS, it's

Note: ACARS frequencies vary by region. Common frequencies in North America include 131.550 MHz, 131.725 MHz, and 130.025 MHz. In Europe, 131.725 MHz and 131.825 MHz are widely used. 4. Launching the Decoder
One of the most practical advanced uses is to run Acarsdeco2 on a low-power computer like a Raspberry Pi. It can decode the messages and then send them over the network to PlanePlotter running on a more powerful Windows PC. This approach is efficient and offloads the processing from your main machine.
