Eeprom to Tx causes recalibration?

[flashbang]

When I write my ER9X Eeprom to the Tx in companion9x V0.56 R812 I have to recalibrate my sticks. Is this normal?
Thanks

Yes

I'm curious if there is more explanation. I've been having quirky issues with calibration lately.

Hmm never had a problem, I calibrated once after flashing the first time and never redid it, even across firmwares...
Of course I save and restore my EEPROM each time I flash.

If you do not download your eeprom from the TX, all calibration data are reset to default and this happens using either eepe or companion.
A new eeprom cannot contain you radio calibration unless you copy general settings from an already calibrated one...

In all fairness -- it might not be the TX - -because I'm dipping my toe into the craziness which is quadcopters -- and the flight controller or ESC's could be the cause -- or most likely it's the loose nut holding the transmitter.

Just have a look at the main screen that shows the stick positions:


If they behave correctly there, then it's you
With the default calibration they are completely off (half of the stick travel does nothing).

I must try this. Which option does one use.
Read Eeprom from TX
or
Read Eprom memory to file
or does it matter?
Thanks

Read from TX reads and shows you the document in C9X. Then you can edit it and save it to a file manually if you want.
Read to file just directly saves to a file, which you can of course later open to edit.

Just a slight practical difference

Thanks, that's what I thought.

The calibration data is part of the EEPROM file. If you are flashing a "new" file then the calibration data is new as well.

If you want a new file without the hassle of recalibrating, just copy the "General Settings" (at least in eePe, not sure about companion)

The same apply, as already stated, also to companion.. just copy general settings (or drag it from a calibrated eeprom to a fresh one).
