[TowerTalk] Repairing CDE/HyGain/MFJ antenna rotators

[Clint Talmadge]

I read this post with some interest as I too have a HAM type rotor that I would like to go through. I recently placed a post on TT asking for a repair procedure and was given one in PDF format by a ham who used to repair rotors. He sold a repair kit and the instructions were part of the package.

I must greatly disagree with one step of your instruction though.  Please never use Gasoline as a degreasing agent.  Gasoline is a motor fuel and is VERY dangerous whether or not it is used inside or outside (as suggested on your web site).  There are many commercially available cleaners and degreasers which are not any where near as dangerous as Gasoline and actually do a much better job at cleaning, degreasing and not leaving any residue when done.  Of course with any cleaning chemical follow the directions and heed the warnings of the  manufacturer.

  After repaired my HAMII rotator the other night, I 
  wrote up some details, partly to jog my own memory 
  later and partly to share with others, on doing the 
  repairs.  I put it on my web page Saturday night.  
  See:

  I thought there would be quite a few, if not many, 
  articles out on the web on the same subject but I 
  was surprised to see this was not true.  A long 
  Google search only found one other somewhat 
  similar article on this topic.  I'm sorry now that I didn't 
  take more pictures while I had it apart but perhaps 
  what is there will help someone.

  If this helps anyone to repair their CDE/HyGain/MFJ 
  rotator, then I'm happy.
