AZ EQ6 GT - RA Guide rate is 1/3 the DEC rate???

[Astronome]

Hello all,

I have had a real problem with my AZ EQ6 GT:

I have found that the MOUNT guide rate in RA is 1/3 the guide rate in DEC.  EQMOD is set to 0.9 in both axis??  This seems to have happened when I tried guiding with AA& instead of the normal PHD2?

Is there a mount direct command to alter the RA guide rate.  Bit like the mount commands to dim the polar scope and set park position.

You know one of these serial commands the no one ever uses??

All the best

John
