Relocked with no problems, sitting at LOWNOISE_ASC. I turned on all the ITMX damping since patrick said that it was good, as well as ITMY mode 3,6,7 and ETMX mode 7. Much of the last few hours has been playing with ETMY modes 4 & 5. I will try something and it will look like it works for tens of minutes, then it will just start to slowly ring up, then a bit faster. I've tried a few different settings and all with varying, but similar, results with a time delay of ringing it up.
