    As you already have Pi Zero, use Pi zero's 5v adapter with Pi B for trial.
    Tried and my verdict is my sdr dongle is the fault even found an app for Android and tested it on there it gets scorching very quick 1-2 mins then stops sending data, dismantled it and back of pcb is discoloured under both of the main chips.

    This was a cheap and cheerful one from China and has lasted about 18 months any recommendations on another or do they all eventually burnout as I know they all run warm

    This one is very nice: https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/

    You could even get their LNA if you want really good reception (rtl-sdr.com/new-product-rtl-sdr-blog-1090-mhz-ads-b-lna/)

    There are some dongles with integrated filter and LNA, those are an option as well. (external LNA is way better though)
    (airnav flightstick / flightaware pro stick plus)

    Hi,

    After windows ban trying setup Raspberry PI3 with Jetvision DVB-T stick. I have system running with 1090 Dump and FR24 feeder.
    But this system is deaf, I can have only 2-5 flights decoded one time max distance around 50nm. Same antenna with AirNav Radarbox will give 40-50 flights > 150nm.

    So maybe I have deaf DVB-T dongle?

    tested dongle:

    pi@raspberrypi:~ $ 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
    [R82XX] PLL not locked!
    Sampling at 2048000 S/s.
    No E4000 tuner found, aborting.

    Any thoughts?

    Xavier


    EDIT: Well, replaced Jetvision with Flight Aware ProStick plus and now getting ten time more flights, max distance >200NM
