Periodic errors in the RA drive ....
Do you have capability to tune the drive for this - called PEC ?
I'm pretty vague on the LX200 , but I thought PEC was offered with this .
(Checked by Google - it is a standard feature on the LX200 see
http://www.astronomyforum.net/meade-...-question.html).
Also found this

Not a Meade LX200 user so that's all I can offer , hope it helps.
