Re: [amsat-bb] Homebrew Rotator Question

["George Henry" <ka3hsw@xxxxxxxxxxxxx>]

Check whether your local library has "The Satellite Experimenter's 
Handbook"...  if not, they can probably get it for you thru interlibrary 
loan.  There was an article in there detailing a couple of techniques for 
adding position pots to that type of rotor.  The simplest is the bracket and 
weighted arm that you mentioned.  Another possibility would be belt-driven, 
off the crossboom.  Adding something to the gear train internally would be 
much more complex...
