My application for a Flightradar24 ADS-B kit was turned down but I would still like to contribute. I have some basic electronic knowledge and I'm a good kit builder. What complete kit would you suggest in order for me to start the process of being a contributor. Any suggestions greatly appreciated. Thanks.
Are you asking how to contribute to FR24? (if you are asking that, maybe ask on the FR24 forum) This is a rundown of what you need: https://github.com/wiedehopf/adsb-wiki/wiki/adsb-receiver-shopping-list Kits are usually overpriced or not very good.
I asked to be considered for a kit but was turned down. I'm a short distance from KRDU and am in the final flight path. I wanted to build a receiver and be a contributor so I was looking for a decent complete kit I could buy.
Why don't you just by what's on that list? Kits that are sold as bundles are overpriced and usually not very good. The components in that list will work together.
For feeding pi3 vs pi4 doesn't matter much. The pi4 is newer and better, at the moment it also seems to be the cheaper option. The adsbexchange image won't work for the Pi4 yet as it hasn't been update. But you don't really need the adsbexchange image. If you want to feed adsbexchange, you can do so on the RPi4 doing the following: Write Raspbian Buster Lite to the sd-card: https://www.raspberrypi.org/documentation/installation/installing-images/README.md Ethernet/LAN is easier, but you can also enable WiFi before ever powering up the RPi: https://www.raspberrypi.org/documentation/configuration/wireless/headless.md Make sure you have ssh access.
