Debug telemetry signal from logs

Ground Control Software Mission Planner
1

Hi, I just got back from a test flight, the flight plan executed correctly, but I lost telemetry for quite a large period. I’m not sure what happened, but I think it might have been the signal getting blocked by my car (the laptop was inside the open hatch area).

So the tlogs are not much good, as they are missing large parts of the flight. I’ve got the log files downloaded off the APM.

What parameter do I graph to see signal strength of the telemetry? Can I make a KML of it?

Thanks for any help.

the telemetry radio rssi values are not recorded in the onboard dataflash log.
you can have a look at the tlog, as that will give you some clue as to the distance from base and rssi.
