Black Cat ACARS

A full featured program that decodes and displays VHF ACARS transmissions, available for macOS and Windows.

Tune your VHF radio / scanner to an ACARS frequency and feed the audio into your computer's sound card input, and start receiving and displaying ACARS transmissions in minutes.

Works great with SDR software and virtual audio cables! Run up to 16 ACARS decoders in parallel at the same time, each tuned to a different frequency.

In addition to a pane for each decoder, decodes are also sorted and organized by message type and plane ID, making it easier to find the messages you want without wading through lots of uninteresting messages.

You can change the color scheme and font type/size to your preferences.

Black Cat ACARS is available for download and trial prior to purchase, so you can make sure it works correctly with your setup. It's available for Windows 8 and 10 (Windows 7 is not supported) as well as macOS.

"Have compared your new ACARS decoder to Multipsk and a very expensive commercial decoder. The commercial one would show 4 received and decoded, Multipsk (has never been a great ACARS decoder) did one where your new decoder had 15 received and decoded in the same time frame. Very impressive. Also discovered your Plane list, and Message list windows which are very handy."
- Jerry Schmidt
