I am an enthusiastic Pi user for various projects, Linux is my main OS. Love aircraft but purely as an observer or traveller.
As for feeding ADSB sites I am curious as to reasons we choose some and not others.
I personally started and have stayed with the PiAware system. Main reason for preferring them over FR24 was I found the forum more welcoming and friendly, appreciate many post in both but I tend to ask any questions here.
Also feed FR24 as their web page is brilliant, happy to support, feed and benefit from the extra functions on the site.
ADSB-Exchange I’ve seen some criticism, negative opinions on the fact it is unfiltered. Personally I am unsure about this, is it a security issue? I have no real idea, guessing if it was a security issue it would have been stopped somehow.
ADSB-Hub I don’t fully understand if this is similar to ADSB-Exchange or not, the former offers an image for viewing collected data, the latter does not appear to.
Smart speakers have apps that will verbally announce certain close by aircraft data, a novelty indeed but not sure how useful this is.
I’m sure there are numerous other ADSB Data sites and would be interested to know as to why you maybe choose to feed some over others.
