Finally UAT support!

How's the software side though?

Last time I looked dump1090 worked well, but there was no way to decode UAT packets.

Something on my to-do list, that's now become more plausible with Claude assisting the research.

On the SDR side, dump978 is what most people use, but SDRs are generally not well suited to embedded applications in terms of power / form factor / cost.

Our firmware is fully open source, and our UAT decoder was introduced last year and has been working well (I think we've shaken all the bugs out at this point). We implemented everything from scratch so that it would run efficiently on our embedded RF MCU (TI CC1314). We support both UAT ADSB and UAT uplink (weather / traffic data).

Our firwmare repo is here: https://github.com/PantsForBirds/adsbee. It's always open for bug reports or PRs!

Yeah I had looked into dump978 in the past, but it was broken. I see it had updates back in 2023, maybe it compiles again.

Thanks!
