Hi to the list, I own an Azimuth Elevation rotator Yaesu G-5400B. Since a while I am having a problem: When I turn the azimuth Rotator I can see that the needle when it moves it does not move straight but often it makes a little flick backwards of the turning way. Sometime it seems that the needle stops for a moment. I've been with a friend on a roof and while turning the rotator I did not see any obstructions on the turning way of the rotator. This problem shows whichever way I turn the rotator CW or CCW. Anyone can tell me what could it happen and how to solve it? Any help will be rally appreciated. Thanks' in advance for any help

Some rotors use a potentiometer in the housing to send position information to the control box. Be sure the rotor cable is intact (my puppy dogs really like rotor cable) and if so, next look at cleaning / replacing the pot in the rotor housing...sb

Gents: I experienced a FAILURE of azimuth position. Ordered a new pot, and it turned out that the failure was that the lead going to the wiper had broken. It is very fine wire and broke due to flexing. Poor design, in my opinion. I reinforced it with some tape backed by a tiewrap in the appropriate place to take the stress off that connection.
Good luck! 73, Jim wb4gcs@amsat.org

Enzo and group, I had the same problem two different times over the years with the wire broken of the potentiometer. After the second time, I put a new heavier and more flexible stranded wire on it and it has been fine for the last year. 73, Tom-N9RPQ.
