Greg,
You realize you opened a can of worms when you said you stuck a Rasp Pi on the USB port to monitor the box...
I assume it is running some sort of monitor program and you can then go to the Rasp Pi to see it, or that the Rasp Pi publishes the info that you can read from within your LAN?
Do tell.
WeatherHost, Even though I'm directly below a major feeder arrival path for traffic into Mpls, St Paul International, about 90 miles out, I ended up getting a small Rasp 2, loading the program on from the FlightRadar 24 site, and powering it up with a little blue USB port plug in programmable receiver, which hams and lots of others have developed software for. It makes a great FM radio receiver, too by the way. Anyway, $60 later and a sacrificed disposable pie pan with a 6" piece of wire sticking out of a F type barrel connector, I was hearing planes about 60 miles out. I built a colinear but for reasons that escape me, and lots of looking for shorts, it didn't work any better. My wife demanded the dining room table back again and I never got an outside install done, so maybe with fresh weather and a spot with internet secured in an out building, I'll be ready to rock again. When you do it that way you can be on the air in minutes, literally, but it took nearly a hundred bucks in parts (all of which can be repurposed) to do so. I'd rather have had them give me the box, but that didn't happen even despite my enviable position near the airport.
