I was looking at some traffic this morning and randomly checking the signal strengths of nearby and distant aircraft. It seemed on my setup that right around -32.2 dBFS is where a/c would reliably stop being received, regardless of distance. The distance where this actually happens varies from day to day as atmospherics change and plane direction of travel varies, etc.
I’m curious as to how weak a signal folks are able to receive and theoretically how sensitive the Flightaware hardware ( blue FA Pro stick ) is in practical terms. (I know the stated capability is “over 300 nm” but I think I read where that is also subject to some software audit/rejection in terms of Flightaware )
