Hello everyone. 

I'm quite new to Skydemon - first year of  use, as well as very new to Stratux - just finished building a Europe Flarm version. 

I have a couple of questions, as I wanted to be sure that my Stratux is correctly built and setup. Some questions might seem dumb... but after a couple days of surfing on internet, I was unable to find a clear answer.

Would anyone be able to perhaps clarify the following for me? I am currently using the lastest version of Stratux - 1.6r1-eu026.

1) I got nooelec v3 radios - One seems pre-programmed to 1090 Mhz and the second one to 978 Mhz. Do I need to somehow re-program the 978 Mhz unit to 868 Mhz with some SDR software? Or is this somehow done automatically by the Stratux software?

2) Is there any particular order in which the radios need to be connected to the USB ports of the Raspberry Pi? Or any radio can be plugged into any of the two ports, and the Stratux will somehow detect which radio receives on which frequency?

Thank you @b3nn0 for your great support on this Stratux EU project. I saw on your Github page that the Stratux Flarm should be connected to Skydemon via the FLARM-NMEA protocol;

3) But is there any difference between "Air Avionics AT-1" and "FLARM via Airconnect"? 

4) Should GDL90 protocol be only avoided due to stability issues? Or does it have any eventual advantage over FLARM-NMEA?

Also, what power banks are you guys using, and what autonomy do you get? I still didn't buy one, and I read that some may cause interference with the Stratux unit.

Thank you very much in advance.
