And if anyone wants to help contribute data, there are a few ways to get started.

1. The minimal: Raspberry Pi and an RTL-SDR dongle. You can even use the small stock antenna that often comes with a dongle, if you put it near a window.

2. A real 1090 MHz antenna, plus filter + amp will greatly increase your performance, and cost less than $100.

Weidehopf has a shopping list: https://github.com/wiedehopf/adsb-wiki/wiki/adsb-receiver-sh...

As does flightaware: https://flightaware.com/adsb/piaware/build

Software-wise, you have a couple nearly-turnkey solutions. The easiest thing is just to follow the guide at https://www.adsbexchange.com/how-to-feed/ You can even use their custom Raspberry Pi image, and instantly have dashboards and maps and all the cool stuff.

Any “one click buy” resources where I can simply pay for a device to be shipped and put it on my network to ship data back? I have several locations in the US I could colocate such devices.

There are a number of places, ADS-B Exchange sells a preconfigured kit on their website. If the location is one with weak coverage they may even send one to you for free, definitely worth reaching out to them if nothing more then to ask about a bulk discount.

AFAIK they don't allow you to pay for it. They'd pay if they need your location. Otherwise they won't send you anything.

What's the difference between the dongles on the Wiedehopf buyig guide and a "generic" RTL-SDR dongle?

Both dongles he lists have integrated 1090 MHz filters and amplifiers, to improve reception of Mode S/ADS-B signals.
