Choke=little inductor that 'eats' spikes (mounted in series with load) is equivalent to capacitor in parallel with cable in your case.
If fact I suggested a simple approach for your case to reduce high frequency interference that bothers you in short cable situation.
We can debate hours, but if you put just some small inductors in series or capacitors in parallel you will be good.

Ok, now I understand, thanks for clarifying
"Fluctuates between 463% and 464%"? How is that a problem?
Did you ever used an analog PC joystick? On the calibration screen, the spot jumped quite a lot on both axis.
yes, I put 463% and 464% as an example, because I did not calibrate the joystick in that test, it actually moves 1% or so, but on a ray that goes from 350% to 440%, so the movement it is very accentuated.
It will seem little, but with the naked eye you can see the axes vibrate! and it is not a fixed movement but sometimes it is less or more accentuated.
(I have had many joysticks per pc and I've never had a joystick where the axes danced like this)
Leo Bodnar is a member here, you may want to PM him from here, except be aware he is not liable on your modification and he maybe busy. ymmv.
Great ! Yes, I do not pretend to waste time for myself, I understand that they have other things to think about. But I bought their electronics, and I have mounted according to their instructions, if it does not work properly, it is right that they solve the problem.
If you were not there, you kindly helped me, I would send it all back.
I'd disconnect the cable shields from signal ground. Cable shields should be attached to the chassis of the device instead.
I think you are right !!
here's what happened:
This morning we took all the electronics apart and reassembled it, and we checked the various connections.
The joystick worked well, so we checked one of the pins that connects the collective to the main body, and we realized that the GND was accidentally in contact with the metal structure of the joystick.
We have noticed that all joystick potentiometers work well when the GND is in contact with the metal structure of the joystick.
Now I have connected the GND of the card to the metal structure, and it also passes through the GND of the potentiometers and to the cable shielding.
Actually it works great, it does not vibrate anymore!
Do you advise me to connect only the cable shield to the structure and leave the GNDs of the potentiometers connected to the board?
I wrote to LEoBodnar what happened and they also confirmed to connect the GND to the structure.
But they talk about connecting the GND card to the structure, (but actually there are no connections on the board to do this)
Then I do not understand, if the joystick had been built the plastic ?? where did I connect the GND?
Should I build a faraday cage for the card?
