Hi, Bob
I am currently using the Rotator Pal (Build the Rotator Pal, by
Tony Brock-Fisher, K1KP, QST, February 1996). It works very
well. It's circuit is contained within the original control box.
Before a lightning strike took it out, I previously used a
controller I built from a 73 Magazine article (June 1984), called
Elegant Rotating, by W4RNL, L.B. Cebik (hmmm...name sounds
familiar). It worked for many years. The added control
circuitry was in a small box which made it very convenient to
locate strategically around the desktop without taking up a lot
of space.
I think there may have been one or two other designs that came
out recently, but since Rotator Pal works, I didn't pay that
close attention.
