    Basic DVBT stick setup:

    DVB-T sticks must have a RTL2832U chipset and 802T/802T2 tuner.
    Those supplied with FC0013 or similar are not suitable

    Note
    - Don't populate HOST field
    - Don't populate COM/DEV/PATH field

    PiAware / Alternate Dump1090 version or AVR capable output running:

    Note
    - Requires IP/Port populated
    - Don't populate COM/DEV/PATH field*
    * - Only populate COM/DEV/PATH to dump1090 version installed if FR24FEED required to force start it on loading (not already running as service)
    - Disable other data outputs fields as controlled by external Dump1090 configuration

    MicroADSB Stick:

    Note
    - (linux/Pi) Run sudo lsusb and dmesg | grep tty to confirm device port to populate - CASE SENSITIVE!
    - (Windows) Populate COM/DEV/PATH with COMx assigned to MicroADSB

    Windows Feeder Specifics

    When using DVBT stick with windows feeder (mr-dump1090.exe) startup messages may not be passed to the uploader app during launch so errors are not as easily seen.

    When USB not detected or configured wrong you may see:
    [main][i]FR24 Feeder/Decoder
    [main][i]Version: 1.0.18-9/generic
    [main][i]Built on Apr 21 2017 14:51:08 (???/Windows/i386)

    [reader][i]Connecting to DVBT receiver via (exe://mr-dump1090.exe --raw)
    [reader][i]Connected to the receiver, configuring
    [reader][i]Configured, processing messages
    [reader][i]Connection terminated
    [reader][i]Connecting to DVBT receiver via (exe://mr-dump1090.exe --raw)
    [reader][i]Connected to the receiver, configuring
    [reader][i]Configured, processing messages
    [reader][i]Connection terminated
    [reader][i]Connecting to DVBT receiver via (exe://mr-dump1090.exe --raw)
    [reader][i]Connected to the receiver, configuring
    Despite it saying connected to the receiver, it is not.

    To confirm the USB is detected with correct tuner present, you can run mr-dump1090.exe from installation folder:
    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
    Any messages relating to Tuner like below, indicate no Rafael Micro tuner is not present and will likely not be able to receive ADSB signals or be poor at doing so

    [FC0012] no valid PLL combination found for 1090000000 Hz!
    Exact sample rate is: 2000000.052982 Hz
    This is a fitpower FC0012 tuner, only capable of 22 – 948.6 MHz when ADSB is 1090 MHz

    Newer Windows 10/USB installations may detect more than 1 device. Dump1090 can pick the wrong device

    Found 2 device(s):
    0: ■, ┤■, SN: (currently selected)
    1: Realtek, RTL2838UHIDIR, SN: 00000001:
    usb_open error -12
    Error opening the RTLSDR device: No error
    This may require additional commands to be added to the FR24feed config page
    For example above:
    --device-index 1

    It can also be tested at a CMD prompt with dump1090-mr --device-index 1
