Thanks for the logs.
The rotator log only shows a connect at 21:28:34 to 37 and nothing else. Is there a later log? I can see mention of reading and syncing the rotator a lot later in the SGP log, up to 9:46:07 PM.
The communication errors seem to be to do with the telescope, not the rotator.
I'll try to have a look and see if I can see what may be causing the strange position reports. It may take a while, I haven't needed to look at this code for ages and Ron is pushing for a new driver for his new focuser/rotator unit.
