Hello
my station : https://www.radarbox.com/stations/EXTRPI139763
Rbfeeder is on a cubieboard but the flightaware Usb stick pro is on a other machine (ubuntu2004).
Mlat seem's running (you can see below)
pierre@cubieboard2:~$ apt-cache policy mlat-client

But no synchro. Perhaps, my lat an long are wrong , but I can't see where I can check ?
My address is good in my settings.

Did you reboot the computer after installation, if not try rebooting
Please post output of following commands
Note: replace your feeder keys, latitude and longitude by xxxxx when posting in forum.
Code: [Select]
cat /etc/rbfeeder.ini

2 weeks ago, FR24 information by mail :
Important! If you are sharing to other networks alongside Flightradar24, please disable MLAT.
When the installation is complete, please make the change in either the Raspberry Pi’s Web UI or edit the fr24feed.ini config file, please.

No MLAT on FA either?
Are you running my readsb by chance? https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb
It can show when data on the USB bus gets lost, this is usually the cause of MLAT issues.
(check the log as described in the readme on the link above)
Does adsbexchange MLAT work? :)
-
The MLAT client seems to be ok however, try changing as follows
[network]
mode=beast
external_port=30005
external_host=127.0.0.1
Also I dont see any mention of your lat/lon/altitude have you entered them correctly
Due to a bug in the MLAT client restarting by "sudo systemctl restart rbfeeder" does NOT solve make mlat to work. Only Rebooting RPi makes mlat to work

Well is adsbexchange MLAT synced?

What's the station name?
Change the decoder to readsb, it gives better logging for problematic SDRs.
(https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb)
I'll probably also give you a small improvement in reception compared to dump1090-mutability.
It has the same ports open as dump1090.
Again the most common issue is not enough voltage getting to the SDR, for example due to USB extensions or insufficient RPi power supplies.

In rdfeeder.ini ? but no usb dongle on cubie. connection to dump1090 running on ubuntu-server (ip =192.168.0.101)
Also I dont see any mention of your lat/lon/altitude have you entered them correctly
where enter my lat/long ? nowhere in my account/profile . I must write my Lat/Long in rbfeeder.ini ?

ok. I understand

ok my error on network, I thought you were using it solely for RB I wasnt aware the feed was from FA/server
I will leave the suggestions to people who know Linux
Alan

On your station page https://www.radarbox.com/stations/EXTRPI139763 see the grid top left, click on Edit your location and enter your exact lat/lon
Alan

Just to make it clear, the following is not about the rbfeeder MLAT but rather about generally improving the station.
The range is nice but the message rate is suboptimal.
Again, using a more current decoder like dump1090-fa or readsb can help with that.
You could also consider a filter or a uputronics filtered preamp.
Generally for MLAT it's good to give the position as precise as possible (5 decimal digits).
Might not hurt to check FA / adsbexchange: https://www.freemaptools.com/elevation-finder.htm
FA has it on the statistics page i believe, for adsbexchange it's easiest to just rerun the feeder install to put in a precise position.

Sorry Alan but.....I can't click on "edit" ;)

Are you logged in to your account. It may be that the receiver is not linked to your account, it usually linked in a short period of time automatically so contact support with your station number and the email address of your account and ask them to link them
Once done you should be able to amend your lat/lon and should have MLAT

.
I am Hamradio, and I use https://www.egloff.eu/googlemap_v3/carto.php (6 decimal digits) using direwolf (APRS)
Thanks you for this information . I 'll try to replace dump1090 with readsb after read your github website
Perhaps I'll drop cubieboard and try to install docker (version github for rbfeeder for amd64: Linux x86-64) on my ubuntu-server20.04
Have a good afternoon.

Yes I am logged into my account but I don't see my receiver. I'll contact support tomorrow .
Many thanks.

In progress
sudo nano /etc/rbfeeder.ini
add line :
lat=my lat
lon=my lon
alt= my alt
save
sudo systemctl restart mlat-client
sudo systemctl restart rbfeeder
It's running but.....see screenshot.
I'll contact support

I believe it is due to your account not being linked. As a feeder if you click Account/Profile you should have a Business Plan, is that the case
Alan
-
In progress ... ;)
So I'll contact support to link my profile and my feeder.
See you later

@F4HUX
Although your mlat problem is solved, I am curious to know which dump1090 you are running. From your output below it is clear it is NOT dump1090-fa.
huawei@ubuntu-server:~$ sudo systemctl status dump1090-fa
[sudo] Mot de passe de huawei :
Unit dump1090-fa.service could not be found.
I first thought you are running dump1090-mutability, but the top command screenshot of Ubuntu Server says only "dump1090", does not say "dump1090-mutability.

You'll see significantly improved reception switching to dump1090-fa or readsb.
Deactivate the crontab, reboot and install:
https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb
It's simple and the feed clients will keep working as they are as the same ports are provided.

Thanks for the detailed info. I did not expect you are using the very original, the very first dump1090 - the Antirez version.
Hats off to Antirez who created the original dump1090. Now it's various branches & versions dominate the adsb decoder world.
