I just bought a used (originally purchased in 1996) G5400 az/el rotor combo for
my local radio club. The rotors are in great shape. In fact the az rotor is
still in its original wrapping!
Years ago and at another club, I got used to their G5600 rotors, which had
limit switches in both the elevation and azimuth rotors. These limit switches
provided great protection from us neophyte sat ops accidentally jamming the
rotors against their stops.

I know I'd have to install the motor start cap in the controller. Just
wondering about the limit switches.
Thanks,
