Thanks for this! I've been doing quite a bit with the ADS-B and want to add
ACARS and see what I get.

So far mainly using the modes_rx stuff, although dump1090 is way more
efficient and has error correction, modes_rx has kml output and I've been
modding the kml. I think on modes_rx I could pull out all the other output
formats and reduce CPU load. Would be nice to add error correction there
but alas I'm off topic.
