    This topic has been discussed more times than I can remember (and I joined this forum at the very beginning).

    The radar "label" has absolutely no relevance to the data that's being received and used to track a flight.

    As long as flights are being shown on FR24 (unless they're blocked for a reason) and your feed is recognised with a free Business subscription, I wouldn't lose any sleep over this.

    I have been observing the feeding system for a long time now and I think that KCHS1 is absolutely right.
    In my case I have a T-XXXX radar with a max range of 290-330nm (very good diy antenna indeed) and my daily rate of positions sent to FR24 is in the range 55K-65K.
    If the T-XXXX and F-XXXX radars would have the same probability to be shown, then when you click on a plane and you do it tens of times, in 50% of the cases you should see the plane followed by T-XXXX and in the other 50% by a F-XXXX.

    It almost never happens to me to see that my radar is tracking one of the planes approaching my local airport, nor planes flying around the island where I live.
    The advantage here is that in our small island there are just three F-XXXX radars and two T-XXXX ones.
    So itīs easy to see which one is doing the job.
    So, yes, I think despite all the efforts to set-up the radar and a 24/7 activity F-XXXX radars are highly prioritized.

    Also to add to what Jarod has said, we still need T-XXXX Feeders even if they don't show.

    A good example of why, is several days ago four F-XXXX Feeders went offline for a few hours each, two of them where Dublin Feeders, two of them where North West England and if it had not been T-XXXX Feeders the coverage would have been very poor.
    So T-XXXX Feeders are very important to Flightradar24.

    1: it's never a waste, you can also watch your own traffic via virtual radar server and feeding is only 1 extra program.
    2: if you have greater range, those aircraft flying at that range should be picked up then.
    3: i have tested a new fr24 receiver and a rtlsdr mini+adsb# at the same time. Both were picking up different signals, but there is no "faster" receiver, especially with ADSB#.
    4: extra benefit with T- feeders is that you get ground signals. Like cars driving on the roads on their way to and from the airport. Airport vehicles that is.

    And you get premium of course!

    This is how database looks like

    The data includes one (or more) Date + Time fields, is that the UTC time the data burst was transmitted from the aircraft and / or the time when the data was added to the database.

    it also says

    Aircraft shown on map

    I have tried to explain this several times, and I really don't know how to explain this. I will make
    another try. Lets assume we have 5 feeders in London. L1 L2 L3 L4 L5.

    All 5 feeders sees BAW123 and uploads the aircraft to the server

    L1 uploads at 12:34:50 and database is updated with L1 data + L1 radar code.
    L2 uploads at 12:34:51 and database is updated with L2 data + L2 radar code.
    L3 uploads at 12:34:52 and database is updated with L3 data + L3 radar code.
    L4 uploads at 12:34:53 and database is updated with L4 data + L4 radar code.
    L5 uploads at 12:34:54 and database is updated with L5 data + L5 radar code.


    Does that mean it's the slowest feeder that's shown, not the fastest?

    The Radar is only listed as Filter when it's actually receiving anything. And shows up on the fr24 website.
    A page refresh when you are sure your radar is used will make it show up.

    F- feeders are VERY fast, and the data often timestamped better via GPS than NTP lookup. The server will use this data as it will appear to be earlier than your own in some cases. THe filter is dynamic, it will only show the current active data being seen at that time.
