ADSB.im

FlightAware ADS-B Flight Tracking
1

Morning All,

I am using the suggested method of feeding multiple aggregators and using ADSB.im which was very easy to get up and running but I am getting a lot of issues and cannot find support to assist me in troubleshooting. I have comprehensive logging of all the aggregators through Dozzle but I don’t really know how to proceed.

This is how things are looking currently but it constantly changes:

Feeders
Feeders928×645 39.9 KB

Is anyone able to help or point me in the right direction to ask for help? I have lots of log data but unsure how to interpret it to be honest with you.

Thanks in advance

David

Hi David,

Maybe @dirkhh or @wiedehopf are able to assist you with that, Dirk is the creator of the software and Wiedehopf is very knowledgeable about it as well.

Thats handy to know, thanks for that Tom

for FA MLAT issues you can go read the thread “MLAT red” next to this.
Bad MLAT is discussed here regularly.

plane.watch showing bad status is likely on their side (assuming the share key is correct, no extra spaces or something maybe?)

In other words: adsb.im is working fine :slight_smile:

Good Morning,

Looking at the logs in Dozzle I have noticed these constant errors:

What’s the log for ultrafeeder then?

you cut off the startup (or rather last crash) … probably constantly restarting …
filtering for readsb helps.

Probably it’s just a bad SDR.

Sorry not sure how to filer the log but this is the most recent mention of READSB

It’s not hard, there is something like a search box in dozzle.

If you can’t find the error, can only guess.

You could disable all the aggregators you see there … the log becomes simpler then.

It’s an Rpi 3 and the FlightAware dongle is connected directly to it and not through a USB extension

Many thanks for your assistance I will get a new dongle ordered
