| In the summer of 2020 we start to overhaul our rotator of the 12M/17M beam. We found out that all of the four rotator need the same overhaul. Some make a bad noice when turning, some has bad potentiometer to read out the direction. The rotator it self is about 20kg and its heavy. | ||
|  | All parts are take out, cleaned and refurbisched if needed. 
 | |
|  | New end switches, interference suppression filter and a new read out with current loop is added in side the rotator. | |
| At last the rotator is sandblasted, two layer of primer and an nice green finishing layer. A photo album for this project is on-line |
