Today I setup the original hexacopter I built with the uAvianix PingRX ADS-B receiver. (ADS-B In)
I will have more detailed videos in the near future. Look for the red light on the device to blink when ADS-B data is being received. This worked indoors surrounded by a steel building. An airport was nearby about 1 mile from this location.
