I keep wondering about ADS-B coverage--or in my case, the lack of it. This morning, for example, I flew 1.5 hours, but FlightAware "saw" me for only about 3 minutes of that time. That was GOOD--it didn't see me at all in the previous three flights. But the interesting thing is that for this flight I had the 740's Ghost Traffic filter turned off, and the only time I saw a ghost was during the same period that FlightAware tracked me.

I'm turning that filter back on, though. It's too spooky, seeing traffic displayed so close.

Do you see any other traffic on FA/FR24 in that area? Is it flat or hilly/mountainous? It initially looks like there might just be a guy down there who has an ADS/B receiver paired into his computer to track airplanes in his area - that's how pretty much all of those websites work.

Flatland. The hills start 100 miles west. You might be right about the guy with the receiver.  Hah. I knew about that and had even applied to one of those apps to do it myself--but had somehow conflated that with the ADS-B system capability. I'm so grumpy about ADS-B's inadequacies that I probably overlook how well it does work.

It can be very spotty, I spotted this just now as an example of holes in ADS/B exchange data streaming
