Motor Issues with OpenSpa images

Could any one else check to see if they have any issues with driving their motor using usals on openspa images 7.0.02 and 7.0.03. I have set up using usals using my long and lats. Ok on 28.2e but try moving the dish to 0.8w and the motor is out of line. I have tested on version 7.0.02 and .03 and 19.2e ok but the further west I go the more the signal are out. I know the motor is bang on as using the same settings in any other image and I have no issues bring in any signals, including very hard to get channels on 7w. I was wondering if anyone else has noticed this issue.
