FSUIPC and a Noisy CH Throttle Quad

[jdriskell]

Apparently my CH Throttle Quad has become noisy.  Inputs from the first two levers, QX and QY, jump around when the levers are in the full closed position.  The other four levers seem to provide smooth inputs.  I've tried recalibrating both levers in FSUIPC but they remain noisy.  I finally recalibrated all the levers using the detent position as fully closed which seems to eliminate the noise.  I'm wondering if anyone on this list has had a similar problem.  Could this problem stem from a voltage issue at the USB port and if so, how could l verify this?  Should I try another USB port and if I did, would I have to recreate all my A/C specific profiles because of changing letters/numbers sensed by FSUIPC.

 

Maybe it's time for a new throttle quad since I have had this one 6-8 years.

 

Thanks in advance for any information.

I'm not really an expert of the actual physics and electrical characteristics of these things, but, yes, trying other cables (if replaceable) and USB ports is worthwhile. As long as you are using the joystick letters FSUIPC won't lose track.

 

I don't know whether the CH quad uses optical encoders or potentiometers, but in the latter case I've used electrical switch cleaner to good effect.

 

I assume you've already checked that you haven't got dual assignments to those two axes, in FS and in FSUIPC? Check that controllers are disabled in FS if assigning in FSUIPC.

Hi Pete,

 

Thanks for the input.  No dual assignments and FS is disabled.  I'm going to try a powered USB hub and if that doesn't work, I'll try cleaning the pots.  Otherwise, I guess I've gotten my money's worth out of the old ones and I'll replace them.
