Decoding HFDL ACARS with a WebSDR and PC-HFDL

This video demonstrates how to decode ACARS messages transmitted via HFDL (High Frequency Data Link) using PC-HFDL. You do not need your own Software Defined Radio or HF antenna to perform the decodes. There are hundreds of people who make their SDRs available via the web at no cost to you. To see my video on using Web SDRs check out To see my video on decoding HFDL with your own SDR and HF antenna, visit In this video I used the WebSDR hosted by the university of Twente in the Netherlands - I also used Vincent Burrell’s free VB Audio Cable to route the audio to PC-HFDL.
