I am very surprised that AIRNAV has not made an ACARS Decoder/feeder for the Raspberry pi since their legacy program was the ACARS decoder, to begin with. I have been actually thinking of shutting down my Radarbox feed from my Piaware and setting up a second Pi3B+ feeding Radarbox with 1090 data and setting up the VHF airband feed too. But.... in my mind what would really compliment the 1090 feed would be an ACARS or VDL2 decoder/feed.
