In December 2018, I started participating in
FlightAware's network of radio receivers that
facilitate tracking of 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:
The switch 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, over 200 feet).
The PoE switch draws about 3 watts without the Raspberry Pi connected
and about 8 watts with it connected and running.
The switch's input current waveform is the lower
trace in the image to the right (not that I think
anyone has a burning need to see it). The upper
trace is the 120V line voltage waveform for reference.
I'm located between two mountain ranges.
Terrain limits my receiver's ability to receive signals in most directions,
