Re: Homebrew Rotator Question

Hi Paul,
 Here is page I chanced upon whern researching homebrew rotor systems awhile 
back. This is a mod for the newer radio shack 3 wire type rotors but it may 
give you some ideas. www.dougbraun.com/rotor_mod.html  I don't know if you 
actually already have the alliance rotator but if you're looking for an 
alternative you can go to www.summitsource.com and look at part # G5-WRMO 
which are replacement rotator units for the Gemini orbit 360 rotator system. 
This was a 5 wire unit with pot already built in that was discontinued a few 
years ago.
