[TowerTalk] ProSisTel 2051d failure.

[William J. Nicosia]

                     I am soliciting comments and actual experience with 
the PST 2051d.

                     My unit was installed a year ago to turn a Mosley 
Pro67C3, which is a heavy antenna. Its 24' 3 inch boom sports 3 elements 
on 40. Its dead weight is about 130 pounds.
                     Recently, the 2051d became erratic and seemed to 
have turned through the South stop point. BTW I'm controlling the 2051d 
with a Green Heron RT-21. Anyway the rotor became less and less 
responsive until it no longer turned at all and just parked itself 
approximately at North. It does not windmill so the worm gear must be 
holding it in place. But it does not turn either and the RT-21 indicates 
an out of calibration condition. BTW the RT-21 will not turn the rotor 
in DEBUG either.
                     Anybody have this experience with a PST and did it 
turn out to be a mechanical failure or something electrical?
