Good morning everyone!
I just recently started up my own piaware station a couple of weeks ago. My setup was a raspberry pi zero w, the blue flightaware stick and, 15 feet of RG-6 and a homemade antenna I placed on the peak of my house where an old satellite used to be. My reception was okay-ish, but rarely picked up anything over 150 miles away and picked up all kinds of signals up to 100 miles.
My wife gave me a raspberry pi 4 for fathers day, so I swapped out the pi zero w for the pi 4 and have seen a massive improvement in the number of signals I’ve received, the number of aircraft seen and my range has improved. I’m picking up way more traffic 150-200 miles away and even seeing a little 200-250 miles.
I am pretty new to all of this and a lot of the radio lingo goes over my head, but I’m curious why did swapping out computers improve my reception? My guess is it’s because the Pi 4 has more processing power and can handle more?
