  • RTL1090 works, but not any other program after adding LNA

    The two first pictures are rtl1090 running and the coverage i get with VRS+RTL1090

    With dump1090, mrdump1090, modesdeco2 i get nothing.

    I might get a few packets if a plane is right over me, but other then that i get zilch...

    Remove LNA, and i get back to my previous covarge that was MAX 190nm (~350km), and dump1090 etc work just fine.

    With the LNA in and with rtl1090 feeding VRS i get 215nm (~400km) all the time...

    Any ideas why rtl1090 would work like a charm and why the others just wont play at all?!?

    Right now my feeder is down due to this and i cant figure it out.

    My guess would be gain settings.

      Tested auto and manual gain and no difference...

        Gain settings are only variable. I would suggest trying ADSB#, it gives better feedback on frame rates vs. gain, determine with that what gain you want then enter that number into dump1090 or modesdeco2.

            Looks like your LNA overloaded your receiver.

            Happened to me, when LNA is on, I see less planes.
