Sometimes the RAD parameters are not available as a DataFlash chart parameter

It appears that the RAD parameters aren’t always available in the DataFlash logs:

Can someone please explain what the dependency might be - so these values can be displayed?

Thank you.

The radios need to be set for mavlink protocol, not raw.


Thank you @amilcarlucas - I have used RFD900 SiK radios and MavLink from my early copters - but maybe the old BIN file I dug up was from before that. My very first ArduPilot copters only had FrSky receivers. Then TBS Crossfire using CRSF. But by then I had the SiK radios installed.
