    Hi everyone,

    I'm new to ADS-B. Just got started a few days back as a feeder.
    So far i'm liking the Beta5 as is has an overall lower CPU utilization (~10%) compared to RTL1090 with fr24feed (~20%) on my low CPU spec that i run 24/7.
    I will try it on the RPi too in the next few days.

    Cheers!

    i know its early but are there plans for this in the future to take input from other devices, like GNS5890? I believe it gives its output as a raw serial stream.

    It will support pretty much all receivers except for airnav's radarbox.

    @piopawlu: Gain setting seems little bit inconsistent. We need to use '--gain 340' in order to set 34.0

    EDIT:

    Could you also backport this fix? https://github.com/MalcolmRobb/dump1...95a138273fb15d

    The decoder works good on my PI here, but i can still see a high CPU load. Dump1090 uses around 35%, the new FR24 Feeder (Version 20140528-0558) uses nearly 100%.
    I see 2 threads of high load, one is round 94, the other is around 87%. Dump1090 was seen only as one thread, maybe there is some difference.

    But thank you very much for this nice work - good to see that the "low level" T-Feeders are still welcome.

    It depends which version are you referring to. MalcolmRobb's fork have many changes to improve performance. Current FR24 Feeder performance should be similar to antirez's verions, because lib is based on the original dump1090. Unless feeder itself have big overhead.

    Ahh thanks for that hint ... i used the MalcolmRobb fork before. Now i tried it with antirez's version and i expect the same load.
    It seems, that the option --aggressive makes the difference.

    giving this a shot since my rtl1090/fr24 combo keeps stripping callsigns off a/c in my area.

    what happens when it can't find the server? there was a brief outage on the fr24 side and now the feed is offline. i can't restart it remotely (feed is at work), does it keep sending data or self shutdown?

    @kasper93: I'll have a look at this, but it may need to wait a while
    @Filldo: It should keep reconnecting until it succeeds
