This clearly shows it’s using the USB stick.
So no, there is no other configuration, as i said the sticks look the “same” to the machine.
As i said, my guess would be that you have strong interference that is overloading the ProStick+ but not the Nooelec due to their different design.
Oh btw, the paperclip should be a better antenna for the Nooelec than those Nooelec antennas (they are not for 1090 MHz, i don’t know why they are labeled as such).
If you’re planning to buy a proper antenna and coax, i’d recommend one of the 1090 MHz filters as well.
You can always run a spectrum scan … would probably be interesting to see on both sticks you have: Do I Need A Filter?
