ACARS

I found https://github.com/antoinet/gr-acars2 and wondered if it could be made to pull in on setup de k9wkj

okay it seems the ADSB block does decode the packets but parsing is ahhh shall we say odd

and of course no output in the telemetry window

Some notes on the situation:

• All of the text you have quoted comes from gr-air-modes and isn't under ShinySDR's control — that is, I can't improve the decoding if there's a problem. (Also, there is some junk, depending on how low you set the Decode threshold control.)
• There's a lot of information that is available but not displayed by ShinySDR, because I don't know enough about the details of these protocols to get the information out of gr-air-modes's returned data structures and label it correctly. Contributions would be appreciated (the relevant code is in https://github.com/kpreid/shinysdr/blob/master/shinysdr/plugins/mode_s/__init__.py, class Aircraft).

I haven't had a chance to look at gr-acars2 yet but I am interested in the idea.

ohh yes I know thats coming from gr-air-modes but i thought it was interesting that it was decoding the packets but couldnt parse things very well i know that ACARS is not the same protocol as ADSB and i didnt see anything in the docs of gr-air-modes that would suggest it could handle ACARS
