I'd like to ask Andrew what the firmware updates need to be.
I've redone the progs recently and it's running with Ascom 6 - and the 497 HB is running with 5EC2 I think is the number off the top of my head.
I haven't had a chance to do an AP run since I updated except a short one onenight that was inconclusive - my Polar alignment is pretty close to spot on and it doesn't really drift at all in Dec. but the RA seems to shimmy back and forth even if the fork is biased one way ( a little excess weight to one side or the other).
If I turn off the GHD Dec axis, would that stop the surge being injected into the RA?
It's all a bit stab in the dark for me and I'd love some intelligent insight into what is happening.

Thanks
