Sadly, in my experience, only Yaesu will service them. YMMV.

On the other hand, my experience with having Yaesu service a G-1000SDX 
rotator was positive, so I'm not knocking them per se, just saying I 
have not found anyone else who will touch them. I had used some mounting 
screws that were too long, and when fully inserted, they broke off some 
bits of metal from inside of the housing casting, which found their way 
into the gears, and cause them to self-destruct pretty badly. Got it 
back from Yaesu service and it has worked fine ever since.

When I got it home and hooked it up in the shop, the Azmiuth rotor was stuck, but some manual help, broke whatever was stuck loose and it started to operate, even abit noisy. The Elevation rotor is nice and quiet and works fine. I notice now, after being used for afew weeks, that the noise is getting more pronounced and also the meter indicator flickers, so I suspect water probably got into the unit.
