I set:
EK2_RNG_USE_HGT = 70
EK2_ALT_SOURCE =0
RNGFND1_MAX_CM = 320
I thought,the rangefinder would be used as primary ALT Source below 224cm, but that doesn’t happen: Rangefinder isn’t used at all.
Here is a log:

btw: when i read this, my feeling is, that even firmware developers are not 100% sure about EK2_RNG_USE_HGT
