Will PM you the CSV file from yesterday afternoon, but in the meantime here are some screenshots from Companion's graphing tool which show the random nature of the logging. As each flying session is made up of at least several launches, I always re-set both 'Flight' and 'Telemetry' after each landing. Interrogating the various 'Flights' (shown as 'sessions') in this file, sometimes all relevant data shows correctly (Alt, RSSI, Ele, Ail), usually at the start of a flying session after which things deteriorate, at other times it is all nonsense, BUT sometimes RSSI, Ele and Ail are correct and it is just Alt that is nonsense. On the TX front, in addition to having switched over to the spare mint 2018 Taranis with its SD card, I also replaced the pill battery for its internal clock - but if you look at the screenshots below you'll see that the time of day recorded is still also a bit random. On the RX front, I haven't removed the foam pad over the vario chip (didn't know about that) but the previous Rx used a separate vario and produced the same problems. I wonder if there's some corruption in the data I transferred from the old SD card to the new one?
