    I must be dumb or something ? When I click Your Account it just tells me I'm online and the last upload time along with links to radar view and a list of all apps available. Where is "More Info"

    ahh, but you need to be running linux feeder 241 or later ... not sure what the windows feeder requirement is for stats (maybe the new feeder)

    Hi guys,

    my Pi was running really a long time without problems,yesterday i had to turn off the power in the room were it is installed......when turning the power on again ... it was dead

    Today i installed the complete PI again...but when i try to run dump1090 i only get the line:

    Hex Mode Sqwk Flight Alt Spd Hdg Lat Long Sig Msgs Ti|

    repeating again and again and again ...

    i started it with this command:


    root@raspberrypi:~/dump1090# ./dump1090 --interactive --net
    Found 1 device(s):
    0: Realtek, RTL2838UHIDIR, SN: 00000001 (currently selected)
    Found Rafael Micro R820T tuner
    Max available gain is: 49.60
    Setting gain to: 49.60
    Exact sample rate is: 2000000.052982 Hz
    Gain reported by device: 49.60
    Hex Mode Sqwk Flight Alt Spd Hdg Lat Long Sig Msgs Ti|

    Im a bit confused about the Sample Rate, not sure, but shouldnt it be 1090 Mhz for ADS-B and where can i change it ??

    Thanks in Advance !

    Hi Guys,

    my RaspPi was running really good, but on Saturday i had to turn the power off in that room.
    Im afraid that something really went wrong when,because my Pi was offline after that.

    On the SD-Card i only had the 'normal' NOOBS Stuff ... no FR-Stuff anymore ??

    Well, yesterday i tried to install it all again, was ok so far .. but when i type rtl_test -t


    rtl_test -t
    Found 1 device(s):
    0: Realtek, RTL2838UHIDIR, SN: 00000001

    Using device 0: Generic RTL2832U OEM
    Found Rafael Micro R820T tuner
    Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6
    Sampling at 2048000 S/s.
    No E4000 tuner found, aborting.



    and when i try to start dump1090 i get the "Hex Mode Sqwk Flight Alt Spd Hdg Lat Long Sig Msgs Ti-" lines ... repeating again and again ...

    ./dump1090 --interactive --net
    0: Realtek, RTL2838UHIDIR, SN: 00000001 (currently selected)

    No 'planes nearby, Antenna is in the cellar and can't get any signals - put it outside the window.

    My RPi always gives me grief if the power is cut off without properly shutting down first. I always find a complete format of the SD card with SDFormatter and then burn the img file you took as a backup (you did take one didn't you ?) normally makes everything work ok. Maybe you are unlucky and the dongle is U/S but it seems to be giving the correct responses.

    Mine always works fine even after it's been unplugged without ceremony so the lawn can be mowed.

    Do you write anything to the file system while it's running?

    Recording stuff in /tmp apparently writes it to memory, but writing it elsewhere writes it to the SD card and there could be inconsistent disc areas where updates are pending.

    (just wondering if such files could be written to a USB memory stick)
