Flight testing conducted this morning. Receiver is a 3 channel EP plane, mounted vertically in the fuselage, stabilisation is not active.
Altitude is not zeroed on power up, but routine to do so is no biggie.
Plane was set into a gentle climb, altitude call outs increased numerically as the plane rose and decreased during descent, but numerical values seemed off; the more I climbed, the more off they seemed, the plane never appeared to be as high as the call outs stated, although that could very likely be uncalibrated old eyes.
Landed the plane, with transmitter about 3' above it, call outs were from -13' to -18'
Back to the stand and with the transmitter and plane at the same level, call outs varied from -3- to -5'.
Powered everything back up, zeroed altitude, repeated test with similar results.
Perhaps span calibration is needed.
Both times when altitude was initially zeroed, call outs were from -.3' to -.8'.
Have you used your vario Lemon DSMP in a plane? If so, did you get believable numbers from it?
I reduced RSSI warn from 20 to 5 as I started getting "receiver low" alarms with the plane barely 30' away. No problems with control at any point, however.
Does raise the question: Does constantly transmitted telemetry "absorb" significant amounts of signal strength?
Vspd tones changed with climb, or descent but I need to get into the audio/haptics to assign monotones at a reduced frequency instead of the nearly continuous warbles given.
Font on your screenshot does look better.
Did you notice on my photo of the Telemetry screen that the Alt Zero values in ft are superimposed over the metric values there when the window is initially opened?
