In December 2018, I started participating in
FlightAware's network of radio receivers that track aircraft.
I have an antenna on a rock in my back yard
connected to a Rasbperry Pi with a USB radio receiver.
See FlightAware's ADS-B page
for more information on their tracking network.

I'm happy to compare notes with others operating FlightAware
receiver sites; my email address is on my
I am using:
Flightaware offers USB receivers with and without 1090MHz bandpass
filters. The filter is definitely recommended in urban areas;
in rural settings the choice depends on how strong various other RF signals
are in your area. I tried both and got better results with the filter.
The Ethernet switch I'm using
gives the option of either 10 or 100 Mbps on its PoE ports.
I chose 10Mbps because that's already more bandwidth
than this application needs and 10Base-T is more reliable
over long cable runs (in this case, about 70 meters).
The PoE switch draws about 3 watts without the Raspberry Pi connected
and about 8 watts with it connected and running.
I'm located between two mountain ranges.
Terrain limits reception in most directions,

been unfazed by outdoor temperatures from 15°F to 100°F.
